       FIELD OF THE INVENTION 
       [0012]    The invention is related to the design of an innovative module to generate surfaces and their parts, that can be used in diverse areas of the construction sector, both in edifices and engineer works, including not only the use of concrete poured into the mold, but also shooting concrete on laminar or solid support shot on mountings and using alternative materials to concrete or cement mortar in some of its parts. Additionally it aims to develop a method to apply said module in the generation of surfaces in the field of building construction and engineer works in different conventional structures. 
       BACKGROUND OF THE INVENTION 
       [0013]    Use of concrete with steel bars goes back to the end of the XIX century to obtain a composite material having the characteristics of concrete as to its resistance to compression and those of steel, most of all regarding its tensile strength. 
         [0014]    The structural concrete elements are fabricated preparing an enclosure by means of a mold known as formwork with the shape of the desired structural element. Steel armatures are placed in the inside of said mold in the areas and direction supporting traction when said element is overloaded, filling afterwards the enclosure with poured concrete and consolidating it by means of bar chopping or vibration. Once concrete sets in and hardens the mold is removed in the procedure known as stripping. 
         [0015]    The different structural elements can also be prefabricated in shop so that once the concrete hardens they can be transported to the construction site. These prefabricated parts might be lightened boring holes inside them as is the case of hollow slabs. Before pouring of concrete previous tension can be applied to armatures as is the case of pre-stressed concrete parts, or said structural elements may have hollow ducts so that once they are placed in the construction site, cables or steel tendons can be introduced through them to tense them afterwards; an operation known as post-tensing. 
         [0016]    However the need of well designed constructive elements built in situ or prefabricated in shop, thus simplifying work in diverse applications in the field of construction and also saving materials and labor with a resulting relevant economic effect, is increasingly evident. 
         [0017]    Patent GB 2023215 of Jun. 15, 1979 to Luddington Enterprises Ltd. discloses a constructive two-walled reinforced concrete element, built by projecting bars overlapping with the armature grills of the walls on a two-sheet support, separated by steel bars either horizontal or in a lattice pattern. However, the connection between the two walls is limited by its relatively weak mechanical resistance; it can only be used in surfaces submitted to low stress as in buildings&#39; closures or small bearing walls. 
         [0018]    Document U.S. Pat. No. 3,982,368 of Dec. 18, 1974 to American Volkscastel International claims a two-walled shot concrete constructive element wherein the cavity between walls is achieved with a wavy carton support sheet. The claimed element has two connectors between walls made up of steel bars overlapping in the armatures of walls. There is another alternative wherein walls are braced by means of concrete partitions provided at a certain distance. The alternative in which bracing between walls is achieved by means of concrete partitions is the one presenting more rigidity, mostly in the direction of partitions while it is scarcely rigid if perpendicularly. The U.S. Pat. No. 3,982,368 invention is designed for prefabricated panels that are assembled in the metallic frames through bolts to the forging borders. It is designed to build only flat surfaces submitted to low stress as in buildings&#39; closures. 
         [0019]    Document DE 19520082 of Jun. 1, 19955 to Bitttscheidt, Norbert, Datteln, discloses a double-walled prefabricated concrete double-walled lost formwork to build vertical packed concrete walls a posteriori. Formwork is not recuperated as in traditional procedures. The proposed system aims to build solid concrete walls instead of hollow ones. It is useful only in vertical surfaces, needing a significant amount of concrete. 
         [0020]    Thus the need of an innovative solution having adequate rigidity in all directions, able to be used in the construction of any surface, even those requiring high resistance requirements as to stress. It should equally be versatile enough so it can be used in the construction of prefabricated panels as Perrin&#39;s, but also to build in situ any surface or edifice; building any surface even with curvature as in vaults, domes or any warped surface, allowing for variable separation between walls allowing adaptation in each spot according to required stress level of said spot. 
       DESCRIPTION OF THE INVENTION 
       [0021]    Features of the Present Surface Generating Module 
         [0022]    The surface generating module of the invention used in a given construction has some features previously mentioned providing at the same time state of the art inventive, novel features. By means of repetition, the surface generating module of the invention generates the full structure. 
         [0023]    In the first place, contrary to normally used art in structure design wherein said structures are made up of linear elements, the ones built according to the invention are made up of elements of a mainly superficial character. Superficial dimensions of surfaces built using the surface generating module of the invention are clearly superior as to their thickness. 
         [0024]    At the same time the concept of formwork to configure an enclosure in which concrete is poured disappears, using in this case a mounting to shoot concrete or mortar on both faces of same. The mounting is not necessarily removed but left inlayed in the surface. Thus it results in a very light element for surface building wherein concrete or mortar is placed only in areas of compression stress originated by structure loading and to cover steel bars supporting tensile stresses. 
         [0025]    The surface generating module of the invention enables construction of all types of structural elements and shapes, either superficial ones as slabs, floor slabs, floors, brackets, vaults, water deposits, contention reinforced walls, bearing walls, closures, partitions, bridge boards, as well as linear structural elements as pillars, bridge piers, beams, girders; also volumetric structural forms as gravity dams o vault dams for water reservoirs. 
         [0026]    The present surface generation module comprises at least two concrete or mortar walls, although they can also be made of reinforced cement mortar, coupled by connectors at a certain distance, which are generally of the same material, or of polymeric material; metallic, wooden; carbon fibers reinforced resin, glass fibers reinforced resin; or any other type of material with sufficient mechanical strength according to requirements of the constructive object to be built. 
         [0027]    As main innovative feature of the surfaces&#39; generating module of the invention is the fact that it increases the inertia momentum of a surface regarding its medium plane, separating walls inwardly without increasing construction material requirements, as is the case of formwork concrete elements, wherein to increase momentum of inertia, thickness of surface has to be increased generating more material consumption, labor and time. Thus, the present element provides very resistant structures with a much lower use of resources. Structures built applying this invention are much more resistant to seismic movement strains. All of this results in an important saving of resources, rendering a significant applicability and an important economic effect. 
         [0028]    Building Procedure 
         [0029]    The following method can be applied to build a surface for any construction using the present surface generating module when using a solid mounting.
       a) Preparation of support as to dimensions and location of surface to be built. The support should be made up of light material, easily moldable, cut and drilled.   b) Drills are bored in said support with the dimensions and shapes of connectors used to join the walls. Drill section coincides with that of the future connector and its depth with connector&#39;s length.   c) Armatures are introduced through drills of future connectors. Armatures carry pins to overlap with wall armatures.   d) Armatures are attached and fixed to each face of support of each future wall.   e) Pins of connectors&#39; armatures are folded and overlapped or welded with armatures of walls.   f) Once all armatures are placed and overlapped on the support and said support is correctly placed according to the shape of the surface, concrete or mortar is shot beginning by filling drills and thus forming connectors, then   g) Concrete or mortar is shot against one of the support faces covering armature and providing required thickness, thus forming one of the walls.   h) Concrete or mortar is shot on the other face of the support covering the corresponding armature, forming the second wall.       
 
         [0038]    If the surface generating module is three-walled, operations previously described are repeated except folding of connector armature&#39;s pins in the face wherein third wall is to be built. Next a second support is attached to the wall already built with drills facing salient pins of connectors so that pins, once the second support is placed, protrude through its drills. Next armatures of second wall are placed. Protruding armatures of connectors are folded and overlapped with those of the third wall and concrete or mortar is shot beginning by filling drills of second support, and next on seen face of second support, covering armatures and thus forming the third wall. If said generating module of the invention has more walls the operation is repeated until completion of all walls. 
         [0039]    Alternatively, connectors can be prefabricated in shop instead of in situ as previously described. In this case, these are cylinders or prisms of reinforced concrete or mortar with two or four parallel drills close to both bases of said elements. Once in the construction site they are introduced in the support drills. Wall armatures are placed at both faces of support and tied bars overlapping armatures of future walls are introduced through connectors&#39; drills. Tied bars introduced in connectors should be impregnated with resin so that they adhere to said concrete or mortar of connector&#39;s drill along contact surface. Once all prefabricated connectors and armatures of both walls have been placed, concrete or mortar is shot on one face of the support, thus forming the first wall and afterwards concrete or mortar is shot on the other face of the support thus forming the second wall. 
         [0040]    Instead of solid as previously described, support can also be made up of two sheets of selected material, separated at a certain distance and hollow inside. Both sheets have facing drills and cylinders or hollow prisms going from a sheet drill to the opposite one. Once double-sheet support is made with specified dimensions of the surface to be built, armatures of future connectors are introduced through the cylinders or hollow prisms. Future walls&#39; armatures are placed in each external face of the support, folding armature pins of connectors, overlapping them with armatures of both walls, casting concrete or mortar beginning by filling cylinders or prisms and next casting concrete or mortar in turns on one face of the support and then on the other. 
         [0041]    In the void between walls diverse conduits as water pipes or electrical tubing can be installed. Also if this space is vertical the surface can be filled with soil and used to plant flowers. If horizontal, the void between walls might be filled with gravel to increase load which could be appropriate in floor slabs or other types of structural elements. Separation between walls of the present generating module of the invention may be variable. Said walls can present any curvature. Before hardening of concrete or mortar begins, if necessary, it can be trimmed, trowelled or given corresponding superficial finish to each wall. 
         [0042]    It is also possible to make up a surface according to the invention when there is no access to one of the surfaces to be built, by preparing a first support without drill with the shape of the future surface; this first support can even be the embankment of an excavation and if so, a first wall armature and connectors&#39; armatures are placed in this support. Next concrete or mortar is shot thus forming the first wall; afterwards a second support is attached to this first wall, being said support solid or of double-sheet. Drills of this second support are arranged so that when attaching same to the already built wall, connectors&#39; armatures are introduced through the drills protruding from them. Next armatures of second wall are placed, folding and overlapping pins of connectors&#39; armatures of second wall casting concrete or mortar, filling drills and covering armatures of second wall, thus finishing same. 
         [0043]    When the generating module of the second wall of concrete or mortar of the invention is to be used as reinforcement of an existing structure, instead of demolishing said wall and building a new one whether it is damaged or deteriorated, or a change of use is desired to increase for example, its loading capacity; the reinforcement method is as follows:
       a) First the structure is tubbed so that work can be carried out safely since the edification proper acts as support for casting of concrete or mortar.   b) According to reinforcement design, a series of drills are bored in all the surfaces to be reinforced.   c) Connectors&#39; armatures are introduced through these drills   d) Next, armatures corresponding to each wall of designed armature are fixed in each face of surface to be reinforced.   e) Connectors&#39; armature pins are folded in each face of the surface, overlapping them with corresponding armatures placed in each wall.   f) Concrete or mortar is shot beginning by filling drills thus forming connectors, next concrete or mortar is shot on one face of the surface, covering existing armature thus forming first wall   g) Next, concrete or mortar is shot on second wall of the surface thus finishing second wall.       
 
         [0051]    Alternatively, connectors can be prefabricated in situ for this reinforcement application. In this case, the work method is similar, but introduction of connectors&#39; armatures and pins folding is substituted by introduction of prefabricated connectors and tied bars impregnated with adherent resin through drills having prefabricated connectors in both bases, overlapping these tied bars with armatures of respective wall. Finally concrete or mortar is shot on both faces. 
         [0052]    Thus former construction is embedded in the double wall formed by said reinforcement. 
         [0053]    Applications of the Generating Module of the Invention. 
         [0054]    Industrial application of the surface generating module for double or multiple concrete or mortar walls focuses mostly on building construction and in engineer works. All types of structural elements, surfaces and architectural forms used in constructions and engineer works can be built with same. 
         [0055]    The surface generating module of the invention enables construction of: foundation slabs, basement walls, load walls, closure walls, separating walls of spaces, pillars, beams, girders, drop forgings, and all types of covers, brackets, vaults, domes, etc. 
         [0056]    Besides the ones previously mentioned, applications of the surface generating module of the invention in engineer works include: construction of water storage deposits, soil containment walls, enclosures for maritime port barriers, abutments, stacks and aqueduct and viaduct bridge boards, gravity dams o vault dams as water reservoirs, revetment of tunnels and galleries and in general, forming of any structure or part of same. 
         [0057]    With the present generating module of the invention any type of conventional elements can be built in the areas of in shop prefabricated reinforced concrete parts to be carried and placed in engineer works, including self carrying panels, floors, pillars and stacks, girders, slabs, etc. These parts can have any required form or dimension. 
         [0058]    The present element is quite useful as a reinforcement system of damaged structures whether in buildings or in different engineer works.

       Embodiment No. 7. General Method 
       [0085]    General building method is as follows: placing support, either of double-sheet  4  or solid  5  with shape and dimensions of the whole surface of the construction to be built or part of it. Armatures  8  of each wall are attached to each face of the mounting, armatures of connectors  7  are introduced through prisms or hollow cylinders  3  of mounting if same is of double-sheet  4  or through drills  6  if solid; pins of longitudinal armatures of connectors are folded and overlapped to armatures  8  corresponding to each wall  1 . Concrete or mortar  9  is shot packing prisms or hollow cylinders  3  if mounting is double-sheet  4  or drills  6  if it is solid  5 , thus forming connectors  2 . The casting of concrete or mortar  9  on one face of the mounting and then on the other continues until achieving required thickness in each wall  1 . If generating module of the invention to be used is three-walled  1  the same method is followed as previously explained except folding pins of armatures  7  of connectors  2  in the face of mounting  4  or  5  where third wall is to be formed. Once concrete or mortar  9  of second wall  1  is shot then second mounting is attached to same so that unfolded pins of connectors pass through hollow prisms or cylinders  3  of second mounting if this is of double-sheet  4  or through drills  6  if it is solid  5 , placing then armatures  8  of third wall  1 . Pins of connectors  2  are folded overlapping them with armatures  8  of third wall  1  filling prisms  9  or hollow cylinders  3  of second mounting with concrete or mortar if said mounting is double-sheet  4  or drills  6  of second mounting  5  if solid, then shooting concrete or mortar  9  on seen face of said second mounting  4  or  5 , completing third wall  1 . If generating module of surfaces has more walls the method is repeated until completion of all of them. Before concrete or mortar sets in, it can be trimmed or trowelled if certain smoothness is needed in the seen face of any wall  1 . 
       Embodiment No. 8. Method without Access to One of the Surface Faces 
       [0086]    Construction method if there is no access to one of the faces of the surface is as follows: a common mounting, not of the invention, is placed with no drills, with shape and dimensions of the surface to be built. Armatures of first wall  8  and armatures of connectors  7  are placed casting concrete or mortar  9  forming first wall  1 ; a second mounting, of double-sheet  4  or solid  5  is attached with prisms or hollow cylinders  3  in the first case or with drills  6  in the second case so that longitudinal armatures  7  of connectors  2  pass through said hollow prisms or cylinders or drills; armatures of second wall are attached to this second mounting, folding and overlapping pins of longitudinal armatures of connectors  7  to armatures of second wall  8 , filling with concrete or mortar  9  hollow prisms or cylinders  3  in the first case or drills  6  in the second case thus forming connectors  2 , casting of concrete or mortar  9  continues on seen face of mounting thus forming second wall  1 . 
       Embodiment No. 9. Construction Method of Surface Attached to an Excavation Embankment or to an Existing Surface

       [0090]    Method to reinforce an existing surface  13  vertical, horizontal or slanted and with curvature is as follows: if necessary it is tubbed in the first place so that following operations are sufficiently safe. Drills  6   a  are bored in said surface  13  according to reinforcement design; armatures of walls  8  are attached to each face of said surface  13  and prefabricated connectors  10  are introduced through said drills  6   a;  tied bars  11  impregnated with resin  12  in their central area are introduced through drills  14  having prefabricated connectors in both bases, placing if the case, second armature grills  8  of walls  1 . Concrete or mortar  9  is cast on both faces of surface to be reinforced  13  until completion of desired thickness of each wall  1 . Once concrete or mortar  9  is cured and sufficiently aged to achieve necessary resistance tubbing of the structure is removed. 
       Embodiment No. 13. Other Prefabricated Elements—Prefabricated Panels and Floating Crates for Port Docks 
       [0091]    Prefabricated panels and construction of floating crates are among other applications of the surface generating method of the invention. 
         [0092]    Prefabricated panels are prepared in shop as follows: joining of panels  15  in situ is carried out through assembly parts  16  and according to  FIG. 13 , said assembly parts  16  are introduced between panels thus rigidly joining said panels  15  after screwing said assembly parts  16 . Width of said assembly parts  16  is somewhat smaller than desired separation between walls of panel  15 . 
         [0093]    Construction of floating crates for port docks is as follows: floating crates have a sill  17  according to  FIG. 14  wherein surrounding walls  18  and separation walls  19  are embedded so that both said walls  18  and  19  are embedded among them. The sill can be concrete double-walled or solid of same material. All said walls  18  and  19  are double-walled of shot concrete or mortar. 
       SUMMARY 
       [0094]    Thus the present invention provides inventive, novel features as to state of the art. The invention develops the present generating module having rigidity in all directions enabling its use in the construction of any surface no matter the stress it may be subject to. The generating module of the invention is much more versatile than any preceding one as to state of the art since it can be used to make prefabricated panels as Perrin&#39;s but also can be directly used in construction works to build any of their parts. Surfaces might have curvatures as is the case of vaults, cupules or any other paddled surface, wherein separation between walls as well as their thickness can be variable allowing adaptation in any spot to required stress level of same. A low caloric conductivity material may be selected to construct the mounting, thus bestowing heat isolation features on the surface constructed according to the invention. Furthermore, structures built applying this invention are much more resistant to strains provoked by seismic movement than conventional ones.
