Description: SPACE JOINT Technical Field This invention relates to a joint for construction elements in mechanical engineering, shipbuilding, civil engineering, as well as in building generally. More specifically, this invention relates to a space joint for rods joining primarily in grid structure's nodes. Technical Background In cases of space joining of crossover joint elements (rods) in three-dimensional nodes, the problem of quick, sustainable, cheap, synchronous, central joint tightening or yielding has been toticed, so that, if necessary, the following could be done in addition: a) whole joint protected from slipping by dynamic forces; b) joint separately insured from slipping of one or more then one rod which is very high forced; c) separate rods protected from dangers while joining and yielding of space joint; d) joint protected from decay while in aggressive environmental condition; e) very high carrying capacity enabled, if necessary; f) joint "warmth" and suitable design for chosen application field insured; g) usage of joint and rods from almost all metals (steel, procron, aluminum, brass, etc.), and nonmetals (wood, plastics, armored concrete, rubber, polyurethane, etc.) enabled; h) joint maintenance reduced to minimum, or quite excluded; I) on already existing construction to enable, with minimum exertion, easy way of extension, and/or additional partitioning, and/or adaptation; j) education to be enabled through space joint usage in play by toys and furniture assembling, etc.; k) if necessary, space joint usage for joining sheeting, panels, or similar, could be enabled; 1) so, if necessary, axes of one or more than one hole or bearing surfaces is not a straight line, or axes do not exist at all; ) with relatively small number of standard space joint body dimensions, coverage of a wide field of rod dimensions and rod shapes is enabled; n) joint body to be used and as a bearing surface for rods, and so makeing tightening and looseing of space joints easier; o) length of space joint body side holes, or bearing surfaces on space joint body and tightening bodies represent bearings with sufficient carrying capacity for compressive loads, and herewith enlarge buckling stiffness. The above mentioned technical problem has been noticed in numerous technical fields, where joining of more rods or other joining elements in nodes, is realized, as for instance: - Maritime (surface and sub-sea) grid structures, as for instance: bridges, pontoons, gates, tourist platforms, foundations, etc.; - Grid structures on land, as for instance: bridges, prefabricated shops, prefabricated houses, prefabricated roofs, partitioning systems, eaves, snow protective structures, power line grid structures, etc.; Partitioning systems, as for instance: in stores and cargo stores (holds) on land, in air, water and on space vehicles, and similar; - Furniture, as for instance: diving room furniture, wardrobes, chairs, beds, shelves, and similar; - Toys, as for instance: folding toys, toys in function of education and furniture, etc.; - Equipment of theaters and circuses, as for instance: stages, scenarios, bearable grid structures, etc.; Equipment of children's recreation places, as for instance: toboggans, swings, bridges, ladders, etc.; Space grid structures, as for instance: space modules, foundations, grid carriers, etc.; - Ornamental (decorative) objects, as for instance: appendages on small chains, appendages for keys, etc. Technical Background Patent application P 950575 A, partially solves some of mentioned problems, but rods have to be singly tightened and loosed. Although this gives the possibility of additional rebuilding, partitioning, or adopting of existing construction, separate intervention on every node is necessary. JP, 05248420 A does not satisfy the following requirements b), e), g), i), k), m), n), and o), and only partially satisfies requirements d), j), 1), while requirements a), c), f), and o) are mainly satisfied. JP, 031 13106 A solves the joining of rods whose axeses are bisected at one point, but a crossover node joint is not dealt with. A wide variety of space joints are known. However, they are not predicted for joining of crossover rods, or joining of crossover rods is solved by minimum of two space joints, or solutions are much wersa than in JP 05248420 A. Description The present invention aims to solve the mentioned technical problem with space joints, by achieving the following: a) enabling the solution of the technical problem through usage of "multipurpose" space joint types ansuring as much as possible wider range of application; b) enabling the solutions of the technical problem by quick, sustainable, cheap, synchronous, central tightening or loosing of rods; c) enabling the solution of the technical problem by synchronous, central tightening of rods from internal of space joint, in such mode to retreat rods into corresponding space joint body holes; d) enabling the solution of the technical problem by synchronous, central tightening of rods from external of space joint, in such mode to retreat rods into corresponding space joints body holes, while rods' tightening or looseing is executed through tightening bodies (covers); e) enabling the solution of the technical problem by synchronous, central tightening of rods from "heart" external of space joint, in such mode as space joint represent the joint upon which the rods are lean against from the external side, and rode tightening is solved through external tightening bodies ("grips"); f) enabling the solution of the technical problem by synchronous, central tightening of rods in such mode that rods' tightening is performed by tightening body "separated part" of space joint; g) enabling the solution of the technical problem in such mode as the space joint if necessary become nondisconnected, of more difficult type to disconnect, as to assure higher joint load capacity, and in that way of whole construction, as to avoid the need for additional problem solving of dynamic loads of constructions, as well as space joints; h) enabling the solution of the technical problem in such mode as the space joint if necessary become non-disconnected, of easier type to disconnect, as to assure higher joint load capacity, and in that way of whole construction, as to avoid the need for additional problem solving of dynamic loads of constructions, as well as space joints, so that the joint could be easy disconnected, if necessary, and so without bigger joint parts destruction; and i) enabling the solution of the technical problem in such mode that space joint internal become isolated of surrounding fluid, if necessary, so to prevent joint parts deterioration due to surrounding fluid aggressive influence. Innovation Preview Summary The technical problem of synchronous, central tightening or loosening of rods by space joints is enabled by usage of space joint type solutions based upon following principals: friction, blocking; final hard joint (easier or harder to disconnect). Basic space joint type solutions are pointed out, as follows: A) SOLUTIONS ON FRICTION PRINCIPLE TYPE I Tightening of rods 1 in a space joint body 2 is performed from the internal side (from inner side) of space joint body through tightening bodies (inserts) 3 placed in space diagonal hole of space joint body and by system for tightening of tightening bodies (inserts), so that the rods must be drawn into corresponding space joint body holes before final rods tightening. Friction force among tightening bodies, rods and space joint bodies is realized by axial moving of tightening bodies along space diagonal hole of space joint body. TYPE II Tightening of rods 1 in a space joint body 2 is performed from the external side (from outer side) of space joint body through tightening bodies (covers) 3 placed outside of space joint body 2 and system for tightening of tightening bodies, so that the rods must be drawn into corresponding space joint body 2 holes before final rods tightening. Friction force among tightening bodies, rods and space joint bodies is realised by axial moving of tightening bodies along space diagonal hole of space joint body. Tightening is enabled by moving of tightening bodies towards space joint body, from space joint body, or combined. TYPE III Tightening of rods 1 in a space joint body 2 is performed from the external side (from outer side) of space joint body through tightening bodies (grips) 3 placed outside of space joint body and system for tightening of tightening bodies, in such way that the rods lean against at corresponding grooves or plane surfaces of bearing part of space joint body "heart" 2, before final tightening. Friction force among tightening bodies, rods and space joint body is realised by axial moving of tightening bodies along space diagonal hole of space joint body, in such way that friction force is realized: a) among rods, tightening bodies and space joint body, b) among rods and tightening bodies only. TYPE IV Tightening of rods 1 in a space joint body is performed from the external side (from outer side) of space joint body through separated tightening body 3 which in principle represent part of the space joint body 2, and system for tightening of tightening body, placed around the space diagonal hole axes of space joint, in such way that the rods must be drawn into corresponding holes of bearing part of space joint, before final rods tightening. Friction force among tightening bodies, rods and space joint body is realized by axial moving of tightening body along space diagonal hole of space joint body. B) Solutions on Blocking principle TYPE V Rods blocking is obtained from a space joint body 2 internal (inner) side (in principle based on TYPE I) by means of blocking bodies 3 situated in space diagonal hole of space joint body. Blocking is obtained by mutual adaptation of the geometry of blocking bodies and rods in ways of blocking, such as: a) by adaptation of rods geometry, only, b) by adaptation of both rods and blocking bodies geometry. TYPE VI Rods blocking 1 is obtained from a space joint body 2 external (outer) side (in principle based on TYPE II to IV) by means of tightening bodies 3 situated outside the space joint body. Blocking is obtained by mutual adaptation of the geometry of tightening bodies and the rods in ways of blocking. C) Solutions on Principle of Easier or Harder Separating Joint TYPE VII Easier or harder separable joint (in principle based on TYPE I to VI) is obtained by rods 1 sticking with: a) space joint body 2, b) space joint body 2 and tightening (blocking) body 3, c) tightening (blocking) body 3. TYPE VIII Easier or harder separable joint (in principle based on TYPE I to VI) is obtained by rods 1 welding with: a) space joint body 2, b) space joint body 2 and tightening (blocking) body 3, c) tightening (blocking) body 3. TYPE IX Easier or harder separable joint (in principle based on TYPE I to VI) is obtained by rods 1 soldering with: a) space joint body 2, b) space joint body 2 and tightening (blocking) body 3, c) tightening (blocking) body 3. TYPE X Easier or harder separable joint (in principle based on TYPE I to VI) is obtained by one of mutual combination of rods 1 : sticking, welding, soldering with: a) space joint body 2, b) space joint body 2 and tightening (blocking) body 3, c) tightening (blocking) body 3. TIGHTENING SYSTEM OVERVIEW In all cases where rods tightening is obtained through tightening bodies (inserts-covers-grips), tightening of bodies themselves is realized in some of following ways: - by screwing joint; - by keying; - by hydraulics; - by pneumatics; - by electromagnetic, or combined. BLOCKING BODIES ASSURANCE SYSTEMS OVERVIEW In all cases of blocking, blocking bodies are assured from falling out by using of some of well-known engineering solutions: split pin; cotter; wedge; nut; elastic full bodied inserts, etc. DRAWING SHORT DESCRIPTION Embodiments of the invention will now be described solely by way of wxample and with referenceto the accompanying drawings in which: Fig. 1.1 Space joint - Space joint body with circular cylindrical space diagonal hole which intersects side holes: a) Right handedness; b) Left handedness; Fig. 1.2 Space joint - Space joint body with circular conical space diagonal hole that intersects side holes: a) Right handedness; b) Left handedness; Fig. 1.3 Space joint - Space joint body with circular cylindrical space diagonal hole which does not intersect side holes: a) Right handedness; b) Left handedness; Fig. 1.4 Space joint - Space joint body with partially circular cylindrical space diagonal hole: a) Right handedness; b) Left handedness; Fig. 1.5 Space joint - Space joint body with stepped circular cylindrical space diagonal hole: a) Right handedness; b) Left handedness; Fig. 1.6 Space joint - Space joint body with space circular cylindrical diagonal hole with six side holes: Right and Left handedness; Fig. 1.7 Space joint - Space joint body with partially circular cylindrical space diagonal hole and with nine side holes: Right and Left handedness; Fig. 1.8 Space joint - Space joint body consisting from outer part and filling - fastening from inside; Fig. 1.9 Space joint - Space joint body consisting from outer part and filling - fastening from outside; Fig. 2.1 Space joint with inner rods tightening, with one tightening body (insert) and with hole in tightening body - TYPE Ia; Fig. 2.2 Space joint with inner rods tightening, with at least two tightening bodies and with hole through tightening body - TYPE lb; Fig. 2.3 Space joint with inner rods tightening, with one tightening body (insert), without hole in tightening body - TYPE Ic; Fig. 2.4 Space joint with inner rods tightening, with at least two tightening bodies (inserts), without hole in tightening body - TYPE Id; Fig. 3.1 Space joint with outer rods tightening towards or off space diagonal with one or two tightening bodies - TYPE Ha; Fig. 3.2 Space joint with outer rods tightening off space diagonal with one or two tightening bodies - TYPE lib; Fig. 4.1 Space joint with outer rods tightening on space joint body "space body heart" (rods are not passing through space joint body) by means of one or two tightening bodies: basic space joint body shape is regular trilateral prism - TYPE Ilia; Fig. 4.2 Space joint with outer rods tightening on space joint body "space body heart" (rods are not passing through space joint body) by means of one or two tightening bodies: basic space joint body shape is circular cylinder - TYPE IHb; Fig. 5.1 Space joint with tightening body as part of space joint body - small tightening surfaces - TYPE IVa; Fig. 5.2 Space joint with tightening body as part of space joint body - enlarged tightening surfaces, without tightening subsystem presentation - TYPE IVb; Fig. 6.1 Space joint with central internal blocking body for three rods synchronous blocking - TYPE Va; Fig. 6.2 Space joint with central internal blocking body for six rods synchronous blocking - TYPE Vb; Fig. 6.3 Space joint with central internal blocking body for three non-circular rods synchronous blocking - TYPE Vc; Fig. 7.1 Space joint with adapted bodies for rods of circular and non-circular transversal section - TYPE VI; Fig. 8.1 Application example of space joint with subsystem for tightening or blocking of tightening or blocking body from inside; Fig. 8.2 Application example of space joint with subsystem for tightening or blocking of tightening or blocking body from inside, with marks for sticking, welding and soldering.; and Fig. 8.3 shows an example of a space joint with a subsystem for tightening or blocking of tightening or blocking body from outside; Preview of drawing reference numbers: Name of space joint element Reference No. Rods 1 Space joint body 2 Tightening body 3 Tightening system for tightening body 4 Securing system for blocking body 5 Stick 6 Weld 7 Sold 8 Adaptable bearing insert 9 Sheathing (panels) 10 For easy of description and understanding, on all drawings, the same reference numbers for the same type of joint element are used.

DESCRIPTION Description of space joint body (Fig. 1.1 to 1.9) For ease of following particular types of space joints in Fig. 1.1 to 1.9, space joint bodies with side holes as well as space diagonal hole are shown. Basic geometric body shape is a cube. By reshaping, space joint functionality and design are obtained. As can be seen from Fig. 1.1 to 1.9 all joint bodies are solid, excluded holes, while joint bodies shown in Fig. 1.8 and 1.9 are of a composite type. Fig 1.1 shows a space joint body 2 (2a - right handedness and 2b left handedness) of cubical shape with three side holes of circular cross section, with a space diagonal hole which is also of circular cross section and which intersects side holes, and two mutually perpendicular cross sections Pl (Pla and Plb) and P2 (P2a and P2b) by which the space joint body is divided (if holes are excluded) in two geometrically mutually identical body parts. The joint body 2 is only partly of modified cubical shape, which is obtained by intersection of body 2 with planes perpendicular to space diagonal. Rods 1 ( 1.1 - 1.3) are shown which are fastened by a space joint. Fig. 1.2 shows space joint body 2 (2a - right handedness and 2b - left handedness) of cubical shape with three side holes of circular cross section, with conical space diagonal hole of circular cross section which intersects side holes, and cross section Pl (Pla and Plb). Fig 1.3 shows a space joint body 2 (2a - right handedness and 2b left handedness) of cubical shape with three side holes of circular cross section, with a space diagonal hole also of circular cross section which does not intersect side holes, and with cross sections P 1 (Pa and Pub) which are obtained by intersection of the joint body with a plane peφendicular to one side hole, and parallel with other side holes. The joint body 2 is only partly of modified cubical shape, which is obtained by the intersection of the body 2 with planes perpendicular to a space diagonal. Rods 1 (1.1 to 1.3) are shown, which are fastened by a space joint. Fig 1.4 shows a space joint body 2 (2a - right handedness and 2b left handedness) of cubical shape with three side holes of circular cross section, with a partial space diagonal hole also of circular cross section which does not inersect side holes, and with cross sections Pl (Pla and Plb) which are obtained by intersection of the joint body with a plane which pases through space diagonal and through two plane diagonals of the joint body. The joint body 2 is only partly of modified cubical shape, which is obtained by the intersection of the body 2 with planes perpendicular to a space diagonal. Rods 1 (1.1 to 1.3) are shown, which are fastened by a space joint. Fig 1.5 shows space joint body 2 (2a - right handedness and 2b left handedness) of cubical shape with three side holes of circular cross section, with a discontinued space diagonal hole also of circular cross section which does not inersect side holes, and with cross sections Pl (Pla and Plb) and P2 (P2a and P2b) which are obtained by intersection of a joint body with a plane which pases through a space diagonal and through two plane diagonals of the joint body, and by a plane peφendicular on that plane and space diagonal respectively. The joint body 2 is only partly of modified cubical shape, which is obtained by intersection of the body 2 with planes peφendicular to the space diagonal. Rods 1 (1.1 to 1.3) are shown, which are fastened by a space joint. Fig 1.6 shows a space joint body 2 of cubical shape with six side holes of circular cross section, with a space diagonal hole which is also of circular cross section and which does not intersect side holes, and with cross sections Pl and P2 which are obtained by intersection of the joint body with a plane which passes through the space diagonal and through two plane diagonals of the joint body, and by a plane peφendicular on that plane and space diagonal. The joint body 2 is only partly of modified cubical shape, which is obtained by the intersection of body 2 with planes peφendicular to the space diagonal. Fig 1.7 shows a space joint body 2 of cubical shape with nine side holes of circular cross section, with a space diagonal hole which is also of circular cross section and which does not intersect side holes, and with cross sections Pl and P2 which are obtained by intersection of the joint body with a plane which passes through the space diagonal and through two plane diagonals of thye joint body, and by a plane peφendicular on that plane and space diagonal. The joint body 2 is only partly of modified cubical shape, which is obtained by the intersection of the body 2 with planes peφendicular to the space diagonal. Fig. 1.8 shows a space joint body 2 of cubical shape with three side holes of circular cross section, and a space diagonal hole which is also of circular cross section and which intersects the side holes. The joint body 2 consists of an outer part (shell) (2.1 a and 2.1 b respectively) and an inner part (fulfillment) (2.2a and 2.2b respectively). The outer shape is only partly of modified cubical shape that is obtained by intersection of the body 2 with planes perpendicular to the space diagonal. The outer body space joint part consists of plane parts and tubular parts which join together to represent a shell casing of the space joint body. Tubular parts of the shell casing are shaped so that the space joint fastening is performed from inside (tightening or blocking or etc.). Fulfillment shape is such as to fulfill space inside the shell casing. Fig. 1.9 shows a space joint body 2 of cubical shape with three side holes of circular cross section, and a space diagonal hole which is also of circular cross section and which intersects the side holes. The joint body 2 consists of an outer part (shell) (2.1 a and 2.1 b respectively) and an inner part (fulfillment) (2.2a and 2.2b respectively). The outer shape is only partly of modified cubical shape that is obtained by cuting of the body 2 with planes peφendicular to the space diagonal. The outer body space joint part consists of plane parts and tubular parts which join together to represent a shell casing of the space joint body. On tubular parts of the joint body there is no special geometrical preparation because, rod fastening by the joint is performed from outside or separately in a side hole. Fulfillment shape is such as to fulfill space inside the shell casing. DESCRIPTION OF SPACE JOINT TYPES SOLUTIONS ON FRICTION PRINCIPLE (TYPE I TO IV) TYPE Ia SPACE JOINT WITH INNER RODS TIGHTENING, WITH ONE TIGHTENING BODY, WITH HOLE IN BODY Referring to Fig. 2.1 , a space joint with central inner rods tightening 1 (1.1 - 1.3) comprises a body 2a or 2b, a tightening body 3.1 a or 3.1 b respectively; or 3.2; or 3.3 ; or similar, a screw 4.1 , a washer 4.4.1.1 , an additional body 4.3.1 , a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1 , a securing 4.2.1 and a nut 4.5. General geometry of the joint body 2 is described in P 950575 A, so that the joint body 2 (Pos. 2a, or Pos. 2b) is cut with two planes that are peφendicular to a space diagonal of the joint body 2 (Pos. 2a or Pos. 2b) that passes through two joint body top points that are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body, so that the surface of the space diagonal hole partly intersects surfaces of the side holes. A tightening insert 3 is used for the rods 1 (1.1 -1.3) tightening to joint body 2 (Pos. 2a or 2b) from inside, so that a tightening force of tightening bush 3 is obtained: a) In use of tightening body 3 (Pos. 3.1a and 3.1b respectively; or Pos. 3.2, or 3.3 or similar) by using a screw 4.1 , a washer 4.4.1.1, an additional body 4.3.1, washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1, a securing 4.2.1 and a nut 4.5, so that on one side of the tightening system has to be secured free entering of all elements in the joint body hole, while from the other side a corresponding washer 4.4 (4.4.1.1 ; 4.4.1.2; 4.4.2.1 or 4.4.2.2) ensures supporting of the joint body. b) Same as in a), so that the space diagonal hole is towards one of diagonal top point of smaller cross section, and in principle adopted to the screw 4.1 dimension. c) Same as in b), so that in the diagonal hole of smaller cross section thread is performed in which the screw 4.1 is screwed, so that for tightening the screw 4.1 , the securing 4.2.1 , the washer 4.4.1.1, the additional body 4.3.2 and the washer 4.4.2.2 can be used. In use of the tightening bush 3 (3.1a or 3.1b) the tightening body must be positioned in the diagonal hole before the rods 1 (1.1 - 1.3) are drawn in. In this case, surface performance against the rods 1 ( 1.1 - 1.3) geometry is enabled so that an unmachined tightening insert is inserted in space hole, tightened with tightening systems from both sides of the diagonal hole, normally while the rods are not drawn in. Machining of the tightening bush surface is now performed through side holes of the joint body 2 (2a or 2b). It is also possible to simultaneously drill holes in the joint body and so, at the same time to get side holes and adapt tightening bush geometry. In case of use of the tightening bush 3 (3.2; or 3.3; or similar), the tightening bushes are performed from more soft elastic material (rubber or similar), the tightening bushes need not be additionally shaped because they are drawn in into the diagonal hole under the relevant load before they are drawn in or after the rods are drawn into the side holes. If a non-ununiform tightening force is requested or friction force on rods respectively, this is obtained by corresponding shaping of the tightening bush 3 and the washers (4.4.1.2 and /or 4.4.2.2). To ensure tightening with rods 1 ( 1.1 - 1.3) of smaller diameter than the diameter of side holes in the body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles and similar), the space between rods circular side hole surfaces is filled with relevant inserts. TYPE lb SPACE JOINT WITH INNER RODS TIGHTENING, WITH TWO TIGHTENING BODIES, WITH HOLE IN BODIES Referring to Fig. 2.2, a space joint with central inner rods tightening 1 (1.1 - 1.3), comprises a body 2a or 2b, a tightening body 3.1a or 3.2a; or 3.1b and 3.2b; or 3.2; or 3.3 respectively, or similar, a screw 4.1 , a washer 4.4.1.1 , an additional body 4.3.1 , a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1, a securing 4.2.1 and a nut 4.5. General geometry of the joint body 2 is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are peφendicular to a space diagonal of the joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body, so that the surface of the space diagonal hole partly intersects surfaces of the side holes. The tightening body 3 is used for the rods 1 (1.1 -1.3) tightening to joint body 2 (2a or 2b) from inside, so that a tightening force of the tightening bush 3 is obtained: a) In use of the tightening body 3 (3.1a and 3.1b respectively; or Pos. 3.2, or 3.3 or similar) by using a screw 4.1, a washer 4.4.1.1, an additional body 4.3.1, a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1, a securing 4.2.1 and a nut 4.5, so that on both sides of the tightening system have to be secured free entering of all elements in the joint body hole. b) Same as in a), so that the space diagonal hole is towards one of diagonal top point of smaller cross section, and in principle adapted to the screw 4.1 dimension. c) Same as in b), so that in the diagonal hole of smaller cross section thread is made in which the screw 4.1 is screwed, so that for tightening the screw 4.1, the securing 4.2.1 , the washer 4.4.1.1, the additional body 4.3.2 and the washer 4.4.2.2 can be used, so that then just one tightening body is used. In use of the tightening body 3 (3.1a and 3.1 b or 3.1b and 3.2b respectively), the tightening bodies need not be positioned in diagonal hole before the rods 1 (1.1 - 1.3) are drawn in. In this case, surface performance against the rods 1 (1.1 - 1.3) geometry is enabled so that an unmachined tightening body is inserted in the space hole, tightened with tightening systems from both sides of the diagonal hole, normally while the rods are not drawn in. Machining of the tightening bush surface is now performed through side holes of the joint body 2 (2a or 2b). It is also possible to simultaneously drill holes in the joint body and so at the same time to get side holes and adapt tightening bush geometry. After tightening the body is drawn out of the hole in the space joint body and the same is transversally cut by such cut thickness that enables sufficient clearance while mutually rods fastening. The tightening bodies can be made in a range of ways, by for example casting, injection, milling, and cuting and similar. In case of use of tightening bush 3 (3.2; or 3.3; or similar), the tightening bushes are made from more soft elastic material (rubber or similar). The tightening bushes need not be additionally shaped because they are drawn into the diagonal hole under the relevant load before they are drawn in or after the rods are drawn into the side holes. If a non-ununiform tightening force is requested or friction force on rods respectively, it is obtained by corresponding shaping of the tightening bush 3 and the washers (4.4.1.2 and /or 4.4.2.2). To ensure tightening with rods 1 (1.1 - 1.3) of smaller diameter than the diameter of side holes in the body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles and similar), the space between rods circular side hole surfaces are filled with relevant inserts. TYPE Ic SPACE JOINT WITH INNER RODS TIGHTENING, WITH ONE TIGHTENING BODY, WITHOUT HOLE IN BODY Referring to Fig. 2.3, a space joint with central inner rods tightening 1 (1.1 - 1.3), comprises body 2a or 2b, a tightening body 3.1a or 3.1b; or 3.2; or 3.3, or similar, a securing 4.2.1, an additional element 4.3.1, a washer 4.4.1, a washer 4.4.2, an additional element 4.3.2, a washer 4.2.2, and a screw 4.1.2. General geometry of the joint body 2 is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are peφendicular to the space diagonal of the joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body, so that the surface of the space diagonal hole partly intersects surfaces of side holes, so that in the space diagonal hole the thread is threaded from the side of new formed diagonal surfaces (thread can be extended and across whole surface of space diagonal hole). The tightening body 3 is used for the rods 1 ( 1.1 -1.3) tightening to joint body 2 (2a or 2b) from inside, so that a tightening force of tightening bush 3 is obtained. a) In use of tightening body 3 (3.1a or 3.1b) by using a screw 4.1.1 , a securing 4.2.1, an additional element 4.3.1 , and a washer 4.4.1 , or by a screw 4.1.2, a securing 4.2.2, an additional element 4.3.2, and a washer 4.4.2, so that one of two corresponding tightening systems of the tightening bush must be released before. One of two tightening systems does not need to exist at all. b) When using tightening body 3 (3.2 or 3.3 or similar) by using a screw 4.1.1 , a securing 4.2.1 , an additional element 4.3.1 and a washer 4.4.1 and /or by a screw 4.1.2, a securing 4.2.2, an additional element 4.3.2 and a washer 4.4.2. c) Same as in a), so that the space diagonal hole does not pass entirely through joint body 2 (2a or 2b). d) Same as in b), so that the space diagonal hole does not pass entirely through joint body 2 (2a or 2b). e) Same as in c) and d), so that in continuation of the space diagonal hole in the non-holed joint body part, a passage is drilled and the passage serves for to drive out the tightening body, compensation passage for the case when the space joint is used in unpressurised fluid, or similar. f) Same as in e), so that in a continuation of space diagonal hole in the non-holed joint body part, a passage is drilled and a thread is threaded in it, and the passage with thread serve for to drive out of the tightening body, compensation passage for the case when space joint is used sunken in unpressurised fluid, or similar. In use of the tightening body 3 (3.1a or 3.1b), the tightening bodies must be positioned in the diagonal hole before the rods 1 (1.1 - 1.3) are drawn in. In this case, surface performance against the rods 1 (1.1 - 1.3) geometry is enabled so that an unmachined tightening body is inserted in the space hole, tightened with tightening systems from both sides of the diagonal hole, normally while the rods are not drawn in. Machining of the tightening bush surface is now performed through side holes of the joint body 2 (2a or 2b). It is also possible to simultaneously drill holes in the joint body and so at the same time to get side holes and adapt tightening bush geometry. In case of use of the tightening bush 3 (3.2; or 3.3; or similar), tightening bushes are performed from more soft elastic material (rubber or similar), the tightening bushes need not be additionally shaped because they are drawn in into the diagonal hole under the relevant load before they are drawn in or after the rods are drawn into the side holes. If a non-ununiform tightening force is requested or friction force on rods respectively, this is obtained by corresponding shaping of the tightening bush 3 and the washers (4.4.1 and /or 4.4.2). To ensure tightening with rods 1 ( 1.1 - 1.3) of smaller diameter than the diameter of side holes in the body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles and similar), the space between rods circular side hole surfaces are filled with relevant inserts. TYPE Id SPACE JOINT WITH INNER RODS TIGHTENING, WITH TWO TIGHTENING BODIES, WITHOUT HOLE IN BODY Referring to Fig. 2.4, a space joint with central inner rods tightening 1 (1.1 - 1.3) comprises a body 2a or 2b, a tightening body 3.1.1a or 3.1.2a; or 3.1.1b and 3.1.2b; or 3.2; or 3.3 respectively, or similar, a securing 4.2.1, an additional element 4.3.1, a washer 4.4.1, a washer 4.4.2, an additional element 4.3.2, a washer 4.2.2, and a screw 4.1.2. General geometry of the joint body 2 is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are peφendicular to space diagonal of joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body, so that the surface of the space diagonal hole partly intersects surfaces of the side holes, so that in space diagonal hole, the thread is threaded from the side of the new formed diagonal surfaces (thread can be extended and across the whole surface of the space diagonal hole). The tightening inserts 3 (3.1a and 3.2a or 3.1b and 3.2b respectively) are used for the rods 1 (1.1 -1.3) tightening to the joint body 2 (2a or 2b) from inside, so that a tightening force of the tightening bush 3 is obtained: a) In using of the tightening body 3 (3.1a or 3.2a or 3.1b and 3.2b respectively) by using a screw 4.1.1, 4.2.1 , an additional element 4.3.1, and a washer 4.4.1 , or by a screw 4.1.2, a securing 4.2.2, an additional element 4.3.2, and a washer 4.4.2. One of two tightening systems, such as neither one of tightening bodies need not be used if high tightening forces are not required. For smaller requested tightening forces, it is sufficient to equip the space joint only with one-sided tightening system, with tightening body included. b) When using the tightening body 3 (3.2 or 3.3 or similar) by using a screw 4.1.1, a securing 4.2.1, an additional element 4.3.1 and a washer 4.4.1 and /or by a screw 4.1.2, an securing 4.2.2, an additional element 4.3.2 and a washer 4.4.2. In this case, the space joint must be equipped with both tightening systems, so that one of them need not to be tightened for smaller requested tightening forces. c) Same as in a), so that the space diagonal hole does not pass entirely through the joint body 2 (2a or 2b), so that in this case the space joint is equipped only with one tightening system and with one tightening element. d) Same as in b), so that the space diagonal hole does not pass entirely through the joint body 2 (2a or 2b). e) Same as in c) and d), so that in continuation of the space diagonal hole in the non-holed joint body part, the passage is drilled and the passage serves to drive out tightening body, compensation passage for the case when the space joint is used sunken in unpressurised fluid, or similar. f) Same as in e), so that in continuation of the space diagonal hole in the non-holed joint body part, the passage is drilled and the thread is threaded in it, and the passage with thread serves to drive out of tightening body, compensation passage for the case when the space joint is used sunken in unpressurised fluid, or similar. In use of the tightening body 3 (3.1.1 a and 3.1.2a or 3.1.1 b and 3.1.2b), the tightening bodies need not be positioned in diagonal hole before the rods 1 (1.1 - 1.3) are drawn in. In this case, surface performance against the rods 1 (1.1 - 1.3) geometry is enabled so that an unmachined tightening insert (cylindrical piece) is inserted in the space hole, tightened with tightening systems from both sides of the diagonal hole. Normally while in the body the rods are not drawn in. Machining of the tightening body surface is now performed through the side holes of the joint body 2 (2a or 2b). It is possible to simultaneously drill holes in the joint body and so at the same time to get side holes and adapt the tightening body geometry. After the machined bush is drawn out from the joint body, the same is transversally cut by such cuting thickness that enable sufficient clearance while tightening the rods from both sides. Normally tightening bodies can be made in a range, for example by casting, injection, milling and cuting, and similar. In use of the tightening body 3 (3.2; or 3.3; or similar), the tightening bushes are made from more soft elastic material (rubber or similar). The tightening bushes need not be additionally shaped because they are drawn into the diagonal hole under the relevant load before they are drawn in or after the rods are drawn into the side holes. If a non-ununiform tightening force is requested or friction force on rods respectively, this is obtained by corresponding shaping of the tightening body 3 and washers (4.4.1 and /or 4.4.2). To ensure tightening with the rods 1 ( 1.1 - 1.3) of smaller diameter than the diameter of side holes in the body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles and similar), the space between rods circular side hole surfaces are filled with relevant inserts. TYPE Ila SPACE JOINT WITH OUTER RODS TIGHTENING, FROM OR TOWARDS THE SPACE DIAGONAL WITH ONE OR TWO TIGHTENING BODIES Referring to Fig. 3.1, a space joint -with central inner rods tightening 1 (1.1 - 1.3), comprises a body 2a or 2b, a tightening body 3.1a and 3.2a; respectively 3.1b and 3.2b, a screw 4.1, a washer 4.4.1.1 , an additional body 4.3.1 , a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1, a securing 4.2 and a nut 4.5. General geometry of the joint body 2 is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are peφendicular to the space diagonal of the joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body. In axes of symmetry of joint bodies, there is a hole for passing through parts of tightening systems. The tightening body can be made in several ways, for example by casting, injection, welding, by combined procedures, or in some other manner. Hole beginning on the tightening body can be made with a spherical recess, for easier use of the joint. For joint body construction, different materials can be used, for example metals (steel, procron, brass, aluminum, duraluminum, bronze, etc.), and nonmetals (GRP, acrylic, wood, polyurethane, etc.), armored concrete, etc. Additional body is described separately for all types of space joints. The washers 4.4.1.1 and 4.4.1.2 are after need for adaptable joint made in a rounded version because of adaptation. The tightening body 3 (3.1a and 3.2a respectively 3.1b and 3.2b) is used for the rods 1 (1.1 -1.3) tightening to the joint body 2 (2a or 2b) from outside of joint body geometry, so that tightening force of the tightening body 3 is obtained: a) By a screw 4.1 , a washer 4.4.1.1 , an additional body 4.3.1 , a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1 , a securing 4.2, and a nut 4.5, the screw 4.1 is used simultaneously for tightening both the tightening bodies 3 (3.1a and 3.2a respectively 3.1 b and 3.2b). b) In case that in space diagonal hole of tightening body of joint body 2 (2a respectively 2b) left or right thread is threaded along whole length of hole, Fig. 4.3 in general case of tightening , by using a screw 4.1 , a securing 4.2.1 , a washer 4.4.1.1 , an additional body 4.3.1 , a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1 , a securing 4.2.2 and a screw 4.1.2. c) Same as in b), except that screws with heads are not used, and studs and nuts are used instead. d) Same as in a), b) and c), except that only one tightening body is used. It is applied for cases when smaller tightening forces are required. e) Same as in a), b),c) and d), except that particular elements of the tightening system are not used: additional bodies (4.3.1 and (or) 4.3.2), some washers. To ensure tightening also when the rods 1 (1.1 - 1.3) are of smaller radius than the radius of side holes on body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles, and similar), hollow space betwen the rods and side circular hole surfaces is filled with corresponding inserts (for example Fig. 7.1). An advantage of this tightening node is that in the side holes of the tightening bodies corresponding bushes are easily inserted, and also those holes can be made with changeable cross section so to enable adaptation of holes themselves to rods, respectively to bushes. A disadvantage of tightening bodies is in that, those bodies can not be positioned afterwards, that is after the rods are pulled through the side holes. TYPE lib SPACE JOINT WITH OUTER RODS TIGHTENING, FROM THE SPACE DIAGONAL, WITH ONE OR TWO TIGHTENING BODIES This type of space joint differs in relation to space joint TYPE Ilia, only in tightening body 3 (3.1a and 3.2a respectively 3.1b and 3.2b). As can be seen from Fig. 3.2 the tightening body 3 is made so that rods 1 (1.1 - 1.3) can be tightened only from the diagonal axes of the joint body. The advantage of this method of tightening is that tightening bodies can be positioned after the rods are pulled through the side holes in the joint space body. This is advantageous in that tightening is achieved only from space diagonal axes. TYPE Ilia and IHb SPACE JOINT WITH OUTER RODS TIGHTENING, TO OPEN JOINT BODY "HEART" WITH ONE OR TWO TIGHTENING BODIES Referring to Fig. 4.1-4.3, a space joint with outer rods tightening 1 (1.1 - 1.3) to joint body "heart", comprises a joint body 2, tightening bodies 3 (3. la and 3.2a respectively 3.1b and 3.2b), a screw 4.1, a washer 4.4.1.1 , an additional body 4.3.1 , a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1 , a securing 4.2 and a nut 4.5. General geometry of the body 2 (2a or 2b) is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are perpendicular to the space diagonal of the joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body, so that the surface of space diagonal hole does not intersect the side hole surfaces. Thus a final joint body 2 (2a or 2b) geometry, as per Fig. 3.1 is obtained in such a manner that from body 2 (2a or 2b) particular outer parts are cut by planes perpendicular to orthogonal joint body 2 (2a or 2b) surfaces. Those surfaces are peφendicular to corresponding diagonals of orthogonal surfaces or respectively parallel to space diagonal. The cut body 2 (2a or 2b) parts, intersect corresponding side holes through the middle or slightly over hole axes, respectively as per Fig. 3.2 and the same as per Fig. 3.1. From joint body 2 (2a or 2b) "heart" additionally joint body parts are removed yet from outside of cylindrical surface whose axes represent space diagonal of joint body, and radius is such that cylindrical surface is tanging planes by whom in precedence the joint body had been cut. General inside geometry of the tightening bodies follows the geometry of the joint body 2 (2a or 2b) "heart", and represents basically the form of regular trilateral prism, Fig. 3.1 or the form of circular cylinder, Fig. 3.2, so to ensure corresponding clearance between tightening bodies 3.1a and 3.2a respectively 3.1b and 3.2.b and joint body 2a respectively 2b, and due to necessity of rods 1 (1.1 - 1.3) tightening to the joint body 2 (2a or 2b). In axes of symmetry of the tightening bodies there is a hole for passing of tightening system parts. The tightening body can be made in, for example by casting, injection, welding, etc. The beginning of the hole on the tightening body can be made with a spherical recess, because of easier joint adaptation. To produce joint body, different materials can be used, for example metals (steel, procron, brass, aluminum, duraluminum, bronze, etc.), and nonmetals (GRP, acrylic, wood, polyurethane, etc.), armored concrete, etc. Additional body is described separately for all types of space joints. Washers 4.4.1.1 and 4.4.1.2 are after need for adaptable joint made in rounded version because of adaptation. The tightening bodies 3 (3.1a and/or 3.2a respectively 3.1b and/or 3.2b) are used for the rods 1 (1.1 -1.3) tightening to the joint body 2 (2a or 2b) from outside, so that tightening force of the tightening bodies 3 is obtained: a) In using of one or both the tightening bodies 3 (3.1 a and/or 3.2a respectively 3.1b and or 3.2b) in general case of tightening, by using a screw 4.1 , a washer 4.4.1.1 , an additional body 4.3.1 , a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1, a securing 4.2.1 and a nut 4.5. b) If in space diagonal hole of joint body 2 (2a respectively 2b) left or right thread is threaded along whole hole length, in general case of tightening, by a screw 4.1.1, a securing 4.2.1, a washer 4.4.1.1, an additional body 4.3.1, a washer 4.4.1.2, a washer 4.4.2.2, an additional body 4.3.2, a washer 4.4.2.1 , a securing 4.2.1 and a screw 4.1.2. c) Same as in b), so that as the tightening body is used the tightening body 3 (3.1a and 3.2a respectively 3.1b and 3.2b) as per Fig. 4.2, and the tightening is obtained by re-screwing of the screws 4.1.1 and 4.1.2, Fig. 3.3. d) Same as in b), except that screws with heads are not used and studs and nuts are used instead. e) Same as in a), b) and c), except that only one tightening body is used. It is applied in cases when smaller tightening forces are requested. f) Same as in a), b) c), and d), except that particular element of tightening system are not used: additional bodies (4.3.1 and/or 4.3.2), some washers. To ensure tightening and in case when the rods 1 (1.1 - 1.3) of smaller diameter from diameter of side holes on body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles, and similar), hollows space between the rods and circular side hole surfaces is filled with corresponding inserts. On Fig. 4.3 joint TYPE Ilia with two screws for tightening 4.1 (4.1.1 and 4.1.2) is shown. TYPE IVa SPACE JOINT WITH TIGHTENING BODY AS PART OF JOINT BODY, WITH SMALL BEARING TIGHTENING SURFACES Space joint TYPE la with (with smaller bearing tightening surfaces) Fig. 5.1 which serves for rods 1.1, 1.2 and 1.3 tightening, comprises a body 2 (2a or 2b), a tightening body 3 (3a or 3a) and system for tightening of the tightening body which in general case can be formed of following parts: a screw 4.1 , a washer 4.2, an insert 4.3, a washer 4.4, a washer 4.5, an insert 4.6, a washer 4.7, a securing 4.8, a nut 4.9. General geometry of the joint body 2 (2a or 2b) is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are peφendicular to the space diagonal of the joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exists the hole which passes diagonally through the whole joint body, so that surface of the space diagonal hole does not intersect the side hole surfaces. From such obtained joint body by suitable intersection of the body 2 with three planes, of which each one is peφendicular to one surface of body 2 which is neighbouring to surface where there is a diagonal hole and passes through diagonal of that surface so that the body part amoung those three planes towards one cut top point of body 2 where there a diagonal hole, the body 3 is obtained, and the remaining part of the body 2 represents the tightening body 3. The tightening body 3 serves for tightening the rods 1 (1.1 - 1.3), so that a tightening force is obtained by tightenings system 4. To ensure tightening also when the rods 1 (1.1 -1.3) are of smaller diameter then diameter of side holes of body 2, or rods are not of circular cross section (elipse, angled profiles, and similar), the hollow space between the rods and the surfaces of the circular side holes are filled with corresponding inserts and also hollow space between rods and tightening surfaces on tightening element. The body of such joint can be easy produced from metals and nonmetals, for example steel, procron, aluminum, brass, duraluminum, wood, GRP, polyurethane, acrylic, etc. The joint body can be obtained in different ways, for example by cuting from quadrilateral rods, by casting, by forging, or by injection. The body holes can be produced during casting, injection, or afterwards, which depending upon material, series, dimensions, technology on disposition, requested quality of performance, and similar. The tightening body can be produced in similar way to the joint body, even and from joint body itself, if it is performed in geometry which includes also tightening body geometry. The threads in the bodies can be made in performed in various ways, for example by casting, injection, subsequent threading, etc. The rods can be rods of shapes such for example as circular, elliptical, angled profiles, bulb profiles, Holland profiles, etc. They can be tubes, of such cross section that can be pulled through the side holes, so that eventual bigger clearances are solved with additional inserts. The rods 1 (1.1 - 1.3) tightening system by means of the tightening body 3 to joint body 2 enables following options of tightening: a) If the space diagonal holes in the joint body 2 and the tightening body are smooth (without threads), than tightening of the tightening body 3 is obtained by the screw 4.1, the washers 4.2 and 4.7, the securing 4.8 and the nut 4.9. b) If in the space diagonal hole of the joint body 2 right or left thread is threaded, it is also used as a nut, than tightening of the tightening body 3 is obtained by the screw 4.1, the securing 4.8 and the washer 4.2. c) If in the space diagonal hole of the tightening body 3 right or left thread is threaded, it is also used as a nut, than the tightening of the tightening body 3 is obtained by the screw 4.1, the securing 4.8 and the washer 4.2. d) If in the space diagonal hole of the joint body 2 and/or in the space diagonal hole of the tightening body right or left thread is threaded, but it is not used, but already only is used free passage inside threaded thread(s), than the tightening of the tightening body 3 is obtained by the screw 4.1, the washers 4.2 and 4.7, the securing 4.8 and the nut 4.9. e) Same as in b), except that the hole in the space diagonal of the joint body 2 is not transitory along the whole length of the joint body. f) Same as in c), except that the hole in the space diagonal of the tightening body 3 is not transitory along the whole length of tightening body. The washers 4.4 or respectively 4.5 are rounded towards the tightening body or respectively the joint body because of adaptation to eventual inaccuracies of the joint, to ensure equal tightening of the joint. It can be combined also with mutual rounding of bodies and washers. TYPE IVb SPACE JOINT WITH TIGHTENING BODY AS PART OF JOINT BODY, WITH ENLARGED BEARING TIGHTENING SURFACES Space joint TYPE IVb (with bigger bearing tightening surfaces) Fig. 5.2 differs from space joint TYPE IVa substantially only in joint body 2 geometry and tightening body 3 geometry, so that tightening body 3 geometry is obtained in such a way that the joint body 2 is cut partially with three planes which are peφendicular to planes in which there are neighboaring surfaces of one diagonal top point and which pass through diagonals of those surfaces up to the middle of the joint body 2, and partially cut with three planes peφendicular to surfaces before mentioned which are also peφendicular to the side holes, so they reach up to the middle of the side holes and reach up to the middle joint body. Advantage of joint Type IVb in relation to joint Type IVa is in enlarged bearing surfaces of the tightening body to the rods 1 (1.1 - 1.3), which can be very useful on some separable joints where bigger tightening forces are required, and by that also bigger friction forces respectively specific loads of tightening surfaces and also is requested that for frequent joint adaptations are minimally damaging smooth rods surfaces. SOLUTIONS ON JOINT BLOCKING PRINCIPLE (TYPE V and VI) TYPE Va SPACE JOINT WITH CENTRAL INNER BLOCKING BODY FOR SIMULTANEOUS BLOCKING OF THREE RODS Referring to Fig. 6.1 , a space joint with central inner rods tightening 1 (1.1 - 1.3), comprises a body 2a or 2b and a blocking body 3. General geometry of the joint body 2 is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are peφendicular to the space diagonal of the joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exists the hole that passes 26 diagonally through the whole joint body, so that the space diagonal hole surface partially cuts side hole surfaces. Rods preparation because of blocking body appliance: a) Rods are drawn in relevant side holes in the joint body and temporarily prevent moving and twisting. Then through the space diagonal hole, machining of rods is performed so that after the machining of rods space diagonal hole geometry for blocking body passing is ensured. b) Preparation (machining) of rods is performed outside joint body on an automatic machine or similar machine by which machining of recess and cuting is enabled. Preparation of the blocking body is extremely simple as such body has a cylindrical cross section. Preventing the blocking body from moving along space diagonal axes of the joint body is enabled by series of common known ways: a) by special head on blocking body; b) cotters; c) split pins; d) by a recess in the space diagonal hole and a thread on part of the blocking body; e) by producing shorter blocking body and applying screw; f) by incorporating a cylindrical seal to recess at the blocking body, and in other ways. The blocking body 3 serves for contemporary blocking of all the rods 1 (1.1 - 1.3) in the joint body 2 (2a or 2b) from inside, so that blocking is obtained by: a) Inserting of the blocking body to space diagonal hole after the rods are drawn into the joint body at right positions and correspondingly twist, the blocking body is secured in hole from axial movement by some of before mentioned ways. b) Same as in a), so at least one rod is not drawn in. An advantage of this space joint is in that it is an extremely simple blocking system, and contemporary is securing the joint from axial movement and from rotation. An additional advantage is that the joint blocking system practically does not need maintenance. An especial advantage is that the joint strength is constant and with extremely easy separating. A disadvantage of this system is in that on rods smaller but permanent recesses have to be milled. To ensure blocking also in case when rods 1 (1.1 - 1.3) of smaller diameter then diameter of side holes on joint body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles, and similar), hollow space between rods and circular side hole surfaces is filled with relevant inserts, so that on those inserts there are appendages of profiles the same as that on rods, by which double blocking is ensured, of insert with rod and of blocking body with inserts. One of possible ways of usage of blocking system is when the rods in the form of angled profiles as shown in Fig. 6.3. The tightening body can be made in several manners, for example by casting, by injection, by welding, by combined procedures and in other ways. Hole beginning on tightening body can be performed with spherical recess, due to easier adaptation of joint. For joint body construction different materials can be used, for example metals (steel, procron, brass, aluminum, duraluminum, bronze, etc.), nonmetals (GRP, acrylic, wood, polyurethane, etc.), armored concrete, etc. Additional body is described separately for all types of space joints. Washers 4.4.1.1 and 4.4.1.2 are after need for adaptable joint performed in rounded version because of adaptation. The tightening body 3 (3.1a and 3.2a respectively 3.1b and 3.2b) is used for the rods 1 (1.1 -1.3) tightening to joint body 2 (2a or 2b) from outside of joint body geometry, so that tightening force of tightening body 3 is obtained: a) By the screw 4.1 , the washer 4.4.1.1 , the additional body 4.3.1, the washer 4.4.1.2, the washer 4.4.2.2, the additional body 4.3.2, the washer 4.4.2.1, the securing 4.2, and the nut 4.5, so that screw 4.1 is used simultaneously for tightening both tightening bodies 3 (3.1a and 3.2a respectively 3.1b and 3.2b). b) If in space diagonal hole of tightening body of joint body 2 (2a respectively 2b) left or right thread is threaded along whole length of hole, Fig. 4.3 in general case of tightening , by using screw 4.1, securing 4.2.1 , washer 4.4.1.1, additional body 4.3.1 , washer 4.4.1.2, washer 4.4.2.2, additional body 4.3.2, washer 4.4.2.1 , securing 4.2.2 and screw 4.1.2. c) Same as in b), except that screws with heads are not used, and studs and nuts are used instead. d) Same as in a), b) and c), except that only one tightening body is used. It is applied for cases when smaller tightening forces are requested. e) Same as in a), b),c) and d), except that particular elements of tightening system are not used: additional bodies (4.3.1 and (or) 4.3.2), some washers. To ensure tightening also in case when the rods 1 (1.1 - 1.3) are of smaller radius then the radius of the side holes on the body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles, and similar), the hollow space between rods and the side circular hole surfaces is filled with corresponding inserts, sea for example Fig. 7.1. An advantage of this tightening mode is the possibility that, in side holes of tightening bodies, corresponding bushes are easy inserted, and also those holes can be made with changeable cross section so to enable adaptation of holes themselves to rods, respectively to bushes. A disadvantage of the tightening bodies is that those bodies can not be positioned afterwards, that is after the rods are pulled through the side holes. TYPE Vb SPACE JOINT WITH CENTRAL INNER BLOCKING BODY FOR SIMULTANEOUS BLOCKING OF SIX RODS Referring now to Fig. 6.2, a space joint with central inner rods tightening 1 (1.1 - 1.6), comprises a body 2a or 2b and blocking body 3. General geometry of joint body 2 is described in P 950575 A, so that the joint body 2 (2a, or 2b) is cut with two planes which are peφendicular to the space diagonal of the joint body 2 (2a or 2b) which passes through two joint body top points which are equidistant from them, so that around the space diagonal exist the hole which passes diagonally through the whole joint body, so that the space diagonal the hole surface partially cuts side hole surfaces. The rods preparation because of blocking body appliance on all six rods simultaneously need something more complex procedure from that of joint TYPE Va. Machining of the rods is performed outside of the joint body by an automatic machine or similar machine by which machining of recesses and inclined cuting of rods is enabled. Inclined cuting of rods is predicted only because of space rationalization in the joint body. The preparation of blocking body is something more complex than with joint TYPE Va. The basic form of the blocking body is a cylindrical rod from which by corresponding machining geometry suitable to rods recesses is obtained. Prevention against moving of the blocking body along space diagonal axes of the joint body is enabled by several known ways: a) by transversal holes and split pins; by special head on the blocking body; b) cotters; c) by thread in space diagonal hole and thread on part of the blocking body; d) by producing shorter blocking body and using screw; e) by incoφorating cylindrical seal in recess on the blocking body, and in other ways. The blocking body 3 serves for simultaneous blocking of all the rods 1 (1.1 - 1.3) in the joint body 2 (2a or 2b) from inside so that blocking is obtained as follows: a) By inserting the blocking body in the space diagonal hole after the rods are drawn in the joint body on right positions and correspondingly twist, the blocking body is secured in the hole from axial movement by some of before mentioned ways. b) Same as in a), except that at least one rod is not drawn in. An advantage of this space joint in relation to that described in joint TYPE Va is in that it is extremely simple system for blocking of more than three rods, by which with system of such joints is enabled easy enlargement of space system configuration relating to width, high and length. A disadvantage of this blocking system in relation to preceding TYPE Va is in that the preparation of rods is slightly more complex. To ensure blocking also in case when all rods 1 (1.1 - 1.3) of smaller diameter from diameter of side holes of joint body 2 (2a or 2b) or rods are not of circular cross section (ellipse, angled profiles, and similar), the hollow space between the rods and the circular side hole surfaces is filled with relevant inserts, so that on this inserts there are profile appendages same as that on the rods by which double blocking is ensured: of insert with the rod and of the blocking body with the inserts. Additional options of rods 1 (1.1 - 1.3) fastenings exist as follows: a) Tightening (fixing) of the rods 6.1 - 6.3, after they are temporarily tightening, is performed by sticking through the space diagonal hole. Separation of the joint is enabled by the action of increased forces on the rods, and in case of a more strengthened joint by corresponding chemical. b) Tightening (fixing) of the rods 6.1 - 6.3, after they have been temporarily tightened, is performed by welding through the space diagonal hole. Separation of the joint is enabled by partial drilling of a weld through the space diagonal hole, so that the rods and the body 2 are partially damaged. TYPE VI SPACE JOINT WITH CENTRAL OUTER BLOCKING BODY FOR SIMULTANEOUS BLOCKING OF AT LEAST THREE RODS There are no substantial differences from joint TYPE V, where the rods blocking in the space joint is obtained from inside. For this type of joint same option of rods and/or tightening bodies adaptation are relevant. C) SOLUTIONS BASED ON EASIER OR HARDER SEPARABLE JOINT PRINCIPLE (TYPE VII, VIII, IX AND X) TYPE VII SPACE JOINT WITH STICKED RODS - EASIER OR HARDER SEPARABLE JOINT By rods sticking bigger joint rigidity is achieved, and so bigger reliability, especially under dynamic loads. The necessary force for producing a quality stuck joint is achieved by using of the tightening bodies, respectively by their tightening. The same or a similar result is obtained by the blocking bodies if those are performed in option with possibility of additional tightening. In appliance of some materials for joint parts and rods, and by using corresponding adhesion additionally, can be ensured also easy separating of a priviously stuck joint by applying of some chemicals, or other. In the case of rods only stuck to tightening bodies and/or blocking bodies, repeated separating of joint is obtained by forced realizing of tightening and/or blocking bodies. Additional fastening of the space joint by sticking can be realized only on those rods for which additional joint safety is required, or for which is not predicted more frequent need for joint adaptation. Sticking can be realized in several phases, for example firstly rods parts are stuck in panel constructions in body or at joint body (force is obtained by means of tightening and/or blocking subsystems), and after temporarily complex space modules, sticking among tightening and/or blocking bodies and rods is performed. TYPE VIII SPACE JOINT WITH WELDED RODS - EASIER OR HARDER SEPARABLE JOINT Within the welded option of creating additional joint strength, several different combinations of welding are possible, for example welding only one single rod, welding of the rods to the joint from outside, welding within inside of the joint body, welding of tightening and/or blocking bodies, etc. A disadvantage of such way of additional fastening of the space joint is in harder separable joint, causes bigger damage of joint parts with forced separating. If it deals only with welding in space diagonal hole, damage appears at the very hole and rod parts in way of weld. An advantage of such possibility of additional fastening of space joint is in that it is firstly a separable joint, and than if necessary is inseparable, and finally a "quasi" - separable joint. This advantage of the joint can be multiple - used when performing various assembling activities on spot, where lots of things have to be adapted before final joint fixing. TYPE IX SPACE JOINT WITH SOLDERED RODS - EASIER OR HARDER SEPARABLE JOINT This situation is similar like the welding one, except that instead of welding procedures, soldering procedures are used. This type of space joint is very interesting for the use of technologically different materials. TYPE X SPACE JOINT WITH COMBINED ADDITIONALLY FASTENED RODS - EASIER OR HARDER SEPARABLE JOINT For joints where combined procedure of additional fastening of space joint is used, it is primarily used for parts usage and additional elements of joints and rods from various materials. DESCRIPTION OF ADAPTIVE BEARING BUSHES (Fig. 7.1) Adaptive bearing bushes are intended for fitting hollow spaces in side holes in space joint body and rods which are fastened in one of predicted ways. Fig. 7.1 shows some options of adaptation for circular and uncircular rods forms. By using bearing bushes, it is possible to join (fasten, block, stick, weld, sold, or similar) rods of various geometrical forms, independently of standardized holes in the joint body. A special advantage is that the rods can be chosen regarding load (form, dimensions, material). Furthermore, by using a bush, fastening of the bush to the joint body can be solved differently from the fastening of a bush and a rod. EXAMPLES OF APPLICATION OF SPACE JOINTS (Fig. 8.1 to 8.3) Fig. 8.1 shows the application of space joints with complete side holes in the joint body. Fig. 8.2 shows the application of space joints in the construction of, for example furniture, where besides joints, rods and panels are used. The panels 10 can be from various materials, for example paper, cardboard, aluminum, plastics, steel, etc., depending of application, load, environment, and similar. Sometimes rods can be used instead of panels. Fig. 8.3 shows me application of a space joint without side holes (rods are reposed on adapted bearing places of joint body before tightening). In particular there is mentioned the possibility of joint applications of specially adapted body and hole form, and after special technical requirements, such as: a) At least one of the holes (side, space diagonal) is not of circular cross section; b) At least one of the holes has geometrical form of rotational body; c) At least one of the holes does not have own symmetry axes; d) At least one of the holes does not pass through whole joint body; e) At least one of the holes is not of constant cross section; f) That exists at least one additional side hole; g) That at least two side holes are inclined under angle different from 90 degrees; h) There exists in at least one of the holes a thread and: * that thread extends along the entire hole length, * that thread extends along only part of hole length; i) That at least one joint body surface is not parallel relating to surface which is on opposite side of joint body skirt; j) That at least one joint body surface is rounded, and in special cases the joint body becomes of cylinder form, sphere, ellipsoid, or similar; k) That at least one of joint top point is rounded, or skewed, or skewed and rounded. MULTILAYERS (HYBRID) SPACE JOINTS As shown in Fig. 1.8 and 1.9, the joint body consists of outer shell and inner part - fulfillment 2.2. Various materials can be used depending upon requirenments such for example isest load, environment, temperature, pressure, and similar. The joint bodies can be used as bodies for all mentioned space joints types, while some of them due to specifically geometry and price are seldom used in practice. OTHER GEOMETRICAL FORMS OF SPACE JOINT BODIES Space joint body for three or more rods can be made, upon special request in various known standard or non - standard geometrical forms: a) regular trilateral prism; b) regular trilateral pyramid; c) regular trilateral truncated pyramid; d) regular quadrilateral pyramid; e) regular quadrilateral truncated pyramid; f) some other application suitable form. APPLICATION OF SPACE JOINT IN COMPLEX AND STRONGLY LOADED GRID CONSTRUCTIONS Because of modularized construction possibilities of such objects, the assembling speed of module themselves and module reciprocally, possibilities of geometry adaptation to field conditions and possibility of easy transformation of separable space joints in entirely or partly in separable joints, same can very successfully be used on length (carrying grid constructions of various applications: bridges, crossings, supports, etc.), at and in sea (pontoons, bridges, platforms, brake - waters, etc.). Space joint can be used and for rods connecting by which are additionally stiffened plane and space grids, so that special additions for the joint body are used, and also space diagonal hole is used for separable and/or inseparable fastening. APPLICATION OF SPACE JOINTS IN LIGHT GRID CONSTRUCTIONS Space joints in different performance options can be used also in space where it is necessary in short term to assemble new construction or already existing one to partition or adapt to new needs. SOME OTHER APPLICATION POSSIBILITIES Due to joint separability and the possibility of simultaneous application of materials with various characteristics which are reciprocally connected, the space joint can very successfully be used in various application conditions and with joints also to ensure an ecological component. The space joint can be also successfully used for various children toys, including toys that are educational. The space joint can also be a useful element of furniture, and similar. The space joint has application in the formation of decorative objects from various materials (wood, various metals, nonmetals,etc), also including precious materials like gold, platinum, etc. Also within welded option of creating additional joint strength, several different combinations of welding are possible, from welding only single rod, welding of rods to joint from outside, welding within inside of joint body, welding of tightening and/or blocking bodies, etc. A disadvantage of such way of additional fastening of space joint is in harder separable joint, resulting in bigger damages of joint parts under forced separation. If it deals only with welding in space diagonal hole, damages appear at the hole and rod parts in the way of the weld. An advantage of the possibility of additional fastening of the space joint is in that it is firstly a separable joint, and than if necessary an inseparable, and finally a "quasi" - separable joint. This advantage of the joint can be multiple - used when performing various assembling activities on spot, where lots of things have to be adapted before final joint fixing. Also within welded option of creating additional joint strength, several different combinations of welding are possible, from welding only single rod, welding of rods to joint from outside, welding within inside of joint body, welding of tightening and/or blocking bodies, etc. A disadvantage of such way of additional fastening of space joint is in harder separable joint, respectively in bigger damages of joint parts while forced separating. If it deals only with welding in space diagonal hole, damages appear at the hole and rod parts in the way of the weld. An advantage of the possibility of additional fastening of space joint is in that it is firstly a separable joint, and than if necessary an inseparable, and finally a "quasi" - separable joint. This advantage of the joint can be multiple - used when performing various assembling activities on spot, where lot of things have to be adapted before final joint fixing.
