AREA OF APPLICATION OF THE INVENTION  
       [0001]     The present invention involves the construction field, more specifically it involves structural wood elements and a corresponding construction system, enabling the construction of buildings, especially walls, partitions, floors, ceilings, etc.  
       DESCRIPTION OF THE PRIOR ART  
       [0002]     Traditionally, the construction of wooden buildings, especially the construction of second homes or vacation villages in the form of cottages, requires the use of costly species, in which the wooden elements are timbered from large tree trunks. The produce of the forests has been considerably diminished and there is a genuine need for better utilization of forest resources, a genuine need to exploit raw material which up to now has been scarcely utilized (little added value). The use of products coming from smaller and/or curved trunks and low-grade wood species, especially those having a tendency to warp, is very limited; they are used essentially as heating wood or as raw material for paper pulp and for the production of wooden panels. Development in the construction of wooden houses, as well as the growth of this economic activity, is ongoing. In fact, wood is experiencing a kind of fad, this material is sought after by the current generation and there is an increasingly large demand for it, which means that the market for wooden construction is steadily growing. On the other hand, the awareness of environmental issues by the population, especially the young people, is leading to new lifestyles, especially in the area of housing, which translates into an increasingly large demand for constructions oriented toward elegant and natural materials. Wood is the especially preferred material for this vibrant market. Wooden construction offers comfort and well being, thermal and acoustical properties, as well as aesthetic qualities appreciated by all.  
         [0003]     Traditionally, wooden construction is made from round wooden timbers, massive planks, or wood core plywood planks, which are stacked on each other and rabbeted at the corners of the construction. More recently and more economically, the construction uses panels to make walls and partitions, constructed from a skeleton, of uprights and stringers, between which are attached stiffening laths, consisting on the outside of wooden panels, an air cavity, and a cladding, and on the inside of wooden lining (wainscot), or some other material. The prefabrication of these panels at the plant is common, and they are assembled afterwards at the work site. More recently, wooden construction has developed toward so-called “kit” systems, structural elements made of wood. This is the particular purpose of the present invention.  
       DESCRIPTION OF THE INVENTION  
       [0004]     The invention consists in an original concept for a construction system (“kit” system), made from structural wooden elements, of simple fabrication, easy to implement and quick to set up, regardless of the location and the circumstances.  
         [0005]     The concept of the wooden construction basically involves the use of structural wood construction elements for the building of structures, especially walls, wall sections, partitions, floors, ceilings, etc. This structural construction element consists of a central block having a parallelepiped structure, on which the base is formed by a groove and the upper part by a tongue (the profile of which is identical to that of the groove), which enables a perfect assembly of central blocks when placed vertically one on the other, on one surface of this central block, on which is secured (by gluing, nailing, screwing, or otherwise) a lateral element of thickness less than the thickness of the central block, of length greater than the length of the central block, and with a height greater than the height of the central block, on which the base consists of a groove and the upper portion of a tongue (the profile thereof is identical to that of the groove), on the surface of this lateral element opposite the surface attached to the central block is assembled another element (by gluing, nailing, screwing or otherwise) of identical useful height of variable thickness, and of greater length, for which the base consists of a groove and the upper part of a tongue (the profile of which is identical to that of the groove), so as make possible means of assembly for other structural construction elements.  
         [0006]     According to the basic provisions of the invention, this structural construction element formed by a central block assembled with two elements, such that the base (formed by a groove) of the central block is perfectly aligned with the base of the two elements attached to one of the surfaces of the central block, allows another structural element with a central block similar to the preceding one, on which and on the surface opposite that of the preceding central block are attached two elements similar to those applied to the first central block, so that these are aligned with the second central block by their upper useful parts, a vertical assembly of structural elements such that, by placing the second structural element mentioned above on top of the first one, the upper part of the central block of the latter (tongue) is fitted perfectly in the base (groove) of the central block of the second structural element, the lateral element which is attached to the central block of the first structural element is still placed by its inner surface (at the block side) against the central block of the second structural element, and vice versa, that is, the inner surface (block side) of the lateral element of the second structural element is still placed against the surface of the central block of the first structural element. These structural elements have assembly bodies arranged on their upper and lower lengthwise edges to enable a vertical assembly of elements one on top of the other, and this without the use of uprights and/or other supplemental connection elements as are traditionally used.  
         [0007]     This invention and this structural construction element offer numerous benefits, among which: 
    its cost, since it can be made from wood of low commercial value as regards the central block, with total utilization of the wood, since the lengths are very short. Furthermore, an industrial mass production is very easy and quick.     its transport and maintenance, thanks to the weight and dimensions and the possibility of interpenetration of the elements.     its ease and speed of assembly, since it is easy to manipulate and it is sufficient unto itself since the alignment, horizontality, and plumbness are produced automatically by the fitting of the tongues in the grooves.     its reutilization, since the construction can be disassembled.    
 
         [0012]     According to one embodiment of the invention, it is also possible to make intersecting structures, which enable the creation of L-shaped structures, as well as T-shaped structures, intersecting or with another angle. The central block of the structural elements which allows one to make this type of intersecting structure has a recess at its lower lengthwise edge and situated perpendicular to the latter, with the same profile as that of the groove situated in the base of the block, which is likewise identical to that of the upper tongue of the central block; the location of the recess perpendicular to the base of the central block, as well as the length and the location of the lateral elements, vary according to the type of structure being made. The perpendicular recess at the base of the central block enables assembly with another central block placed underneath, so that the upper part (tongue) of the latter fits perfectly into the perpendicular recess of the base of the other block, placed at 90°. For the making of intersecting structures with an angle other than 90°, it is sufficient to make the recess at the base of the block with the desired angle.  
         [0013]     Another characteristic of the invention is the fact that the central block of the structural elements is vertically perforated, which allows for the passage of the connection and fixation element of the various structural elements placed vertically, for example, a screw spindle with its accessories, washers, bolts, connectors, etc.  
         [0014]     According to a particularly favorable characteristic of the invention, the species of wood used for the fabrication of the central block, the lateral elements and the lining elements can be different; it is possible to use less elegant and thus cheaper types of wood, depending on the desired technical and aesthetic criteria. For example, it is preferable to use tough and impervious wood for the lining elements placed on the outside, since it will be exposed to the weather; an aesthetic wood more in demand for decorative purposes for the lining elements placed inside; and a hard wood for the central block and the lateral elements, since it will secure the structure of the finished construction.  
         [0015]     Even though the main aspects of the invention that are considered to be innovative have already been stated, more ample details regarding the embodiment of constructions made from the structural elements of wood construction, using the fundamental notions of the invention, will be better understood by consulting the following description and the accompanying drawings, illustrating these embodiments.

     DESCRIPTION OF THE EMBODIMENTS  
       [0024]     As illustrated in the drawing of  FIG. 1 , the structural wood construction element, designated overall as  100 , consists of two central blocks  01  and  04 , inserted between two lateral elements  02  and  05 , which in turn are inserted between two lining elements  03  and  06 . The element  02  is attached to the central block  01 , and on the assembly resulting from these two elements is placed the element  03 , which is attached to the element  02 , these three elements form the structural element  100   a,  the element  05  is attached to the central block  04 , on the assembly produced from these two elements is placed the element  06 , which is attached to the element  05 , these three elements form the structural element  100   b.  The element designated as  100  in  FIG. 1  corresponds to the placement of element  100   a  on top of element  100   b.    
         [0025]     According to the fundamental concept of the invention, the lateral elements  02  and  05  are attached to the central blocks  01  and  04 , the central block  01  is secured to the inner surface of the element  02  at its upper half and the central block  04  is secured to the inner surface of the element  05  at its lower half. The fixation elements (nails, screws, glue, etc.) are placed so as to never be visible after the construction is produced, they are placed in the direction: element  02 —block  01  and element  05 —block  04 . The lining element  03  is attached by its inner surface to the outer surface of the element  02  such that these two elements are aligned at the bottom and top. The lining element  06  is secured by its inner surface to the outer surface of the element  05  such that these two elements remain aligned at the bottom and top. The fixation elements  08  are placed in the direction: element  02 —element  03  and element  05 —element  06 .  
         [0026]     When a structural element  100   a  is placed vertically on top of a structural element  100   b,  they form a structural assembly  100 , the base of the central block  01  enables the insertion of the upper part of the central block  04 , which on the one hand allows the upper and lower lengthwise edges of the structural elements  100   a  and  100   b  to be aligned and leveled, and on the other hand the central block  01  to be placed against the inner surface of the element  05  on its upper half and the central block  04  to be placed against the inner surface of the element  02  on its lower half. When structural assemblies  100  are placed vertically one above the other to produce the construction, supplemental columns or rows, etc., the upper lengthwise edges of the structural assembly  100  fit into the lower lengthwise edges of the next structural assembly  100 , with the tongues of one fitting into the grooves of the other, so as to define the vertical alignment, horizontality, and plumbness.  
         [0027]     According to the invention, the central blocks  01  and  04  are perforated in the vertical direction  07 , to allow for passage of the connection and fixation element, for example, a screw spindle with its supplemental accessories.  
         [0028]     The purpose of the structural construction assembly  110  represented in the drawing of  FIG. 2  is to show a variant of the structural assembly  100 , made from a structural element  110   a,    FIG. 2   a,  and a structural element  110   b,    FIG. 2   b.  These construction elements are more simple than the elements  100   a  and  100   b,  inasmuch as the lateral element has been eliminated from the composition.  
         [0029]     The central blocks, which previously had a flat and clean cross section at their farthermost ends, now have an L-shaped cross section, the lateral element attached to the central block has been eliminated. As illustrated in the drawing of  FIG. 2 , the wood construction element designated as  110  is formed in its entirety by two central blocks  12  and  15 , inserted between two lateral lining elements  11  and  14 , the central block  12  is attached by its largest surface to the inner surface of the element  11  on its upper half and the central block  15  is attached by its largest surface to the inner surface of the element  14  on its lower half. The fixation elements  16  are placed in the ends of the blocks, at the base with L-shaped cross section, so that they are not visible after the construction is produced.  
         [0030]     When one construction element  110   a  is placed vertically on top of a construction element  110   b,  the result is a structural construction element  110  in which the base of the central block  12  enables the insertion of the upper part of the central block  15 , which on the one hand allows the upper and lower lengthwise edges of the structural elements  110   a  and  110   b  to be aligned, and on the other hand the central block  12  to be placed against the inner surface of the element  14  on its upper half and the central block  15  to be placed against the inner surface of the element  11  on its lower half. When structural assemblies  110  are placed vertically on top of each other to produce the construction, primarily of partitions, the lower lengthwise edges of the element  110  will always enable the insertion of the upper lengthwise edges of the preceding structural element  110 , with the tongues of the one fitting into the grooves of the other, so as to define the vertical alignment, horizontality, and plumbness.  
         [0031]     According to the invention, the central blocks  12  and  15  are vertically perforated  13 , to allow the passage of the connection and fixation element, for example, a screw spindle.  
         [0032]     The purpose of the drawing of  FIG. 3  is to show a structural assembly  120  formed by the structural construction elements  120   a,    120   b,    120   c  and  120   d,  representing an angle structure. According to the invention, the structural element  120   a  consists of a central block  31 , which is attached to the inner surface of the lateral element  29  on its upper half, and this assembly is secured to the inner surface of the lining element  27 . The structural element  120   b  consists of a central block  32  of length greater than that of the central block  31 , which is secured to the inner surface of the lateral element  30  on its lower half, and this assembly is secured to the inner surface of the lining element  28 . The structural element  120   c  consists of a central block  26  similar to the block  32 , which is secured to the inner surface of the lateral element  24  on its upper half, and this assembly is secured to the inner surface of the lining element  22 . The structural element  120   d  consists of a central block  25  similar to the block  31 , which is secured to the inner surface of the lateral element  23  on its lower half, and this assembly is secured to the inner surface of the lining element  21 . The central blocks  26  and  32  have, in one of their ends and situated in their base, a recess perpendicular to the respective block  35 , with a profile identical to the groove and to the tongue which are located in the lower and upper edges of the blocks; these recesses allow one to produce an intersecting structure for the structural elements when assembled. The component parts of the structural elements  120   a,    120   b,    120   c  and  120   d  that form the structural assembly  120  are placed so that, when this structural assembly  120  is produced, the central block  26  placed on the block  32  by means of the recess  35  situated at the base of the block  26  and in which the upper tongue of the block  32  fits are positioned perpendicularly, the block  31  and the element  29  are placed against the central block  26 , the block  25  and the elements  21 ,  23  and  24  are placed against the central block  32 , the elements  28  and  30  are placed against the outer surface of the element  21 , and one end of the element  27  is placed against the inner surface of the element  22 . The making of the structural assembly  120  enables upper and lower lengthwise alignments between its elements which, in turn, permit vertical alignment, horizontality, and plumbness when two structural elements  120  are placed one on top of the other,  FIG. 3   a.    
         [0033]     According to the invention, the central blocks  26  and  32  are perforated in the vertical direction  33  and  34 , the perforations  33  are located at the center of the recesses  35  which are located at the base of the blocks, which allows for the connection and fixation of the structural element  120   b  to the structural element  120   c,  these elements make an intersection, while on the other hand the perforations  34  enable the connection and fixation of the structural element  120   c  to the structural element  120   d,  which form one of the sides of the resulting structure  120 , and the connection and fixation of the structural element  120   a  to the structural element  120   b,  which form the other side of the resulting structure  120 .  
         [0034]     The drawing of  FIG. 4  shows a structural assembly  130  formed by the structural elements  130   a,    130   b,    130   c  and  130   d,  representing a T-shaped structure. According to the invention, the structural element  130   a  consists of two similar central blocks  54  and  56 , which are secured respectively to the inner surfaces of the lateral elements  53  and  55  on their upper halves, and these two resulting assemblies are secured to the inner surface of the lining element  52 , leaving a separation between them equal to the thickness of the central block  46 . The structural element  130   b  consists of a central block  49 , which has a length greater than the preceding blocks, which is secured to the inner surfaces of the lateral elements  48  and  51  on their lower halves, and this resulting element is secured to the inner surfaces of the lining elements  47  and  50 , such that the separation between the elements  50 / 51  and the elements  47 / 48  is at most equal to the thickness of the elements  41 / 42 / 43 / 44  added to that of the block  46 . The structural element  130   c  consists of the central block  46 , which has a length less than that of the block  49  but greater than that of the block  54 , it is secured to the inner surface of the lateral element  44  on its upper half and this assembly is secured to the inner surface of the lining element  42 . The structural element  130   d  consists of the central block  45 , which has a length less than that of the block  46 , it is secured to the inner surface of the lateral element  43  on its lower half and this assembly is secured to the inner surface of the lining element  41 . The central block  46  has, at one of its ends and situated in its base, a recess  57  perpendicular to the block, likewise the central block  49  has a similar recess situated at the center and in its base, with a profile identical to the groove and tongue located in the lower and upper edge of the blocks; these recesses enable one to make an intersecting structure for the structural elements when assembled. The component parts of the structural elements  130   a,    130   b,    130   c  and  130   d,  which form the structural assembly  130 , are placed such that, when this structural assembly  130  is produced, the block  46  placed on the block  49  by means of the recess  57  situated at the base of the block  46  and into which the upper tongue of the block  49  fits are in perpendicular position; the central block  46  is placed against the inner surface of the element  52 ; the elements  41 ,  42 ,  43 ,  44  and the block  45  are placed against the block  49 ; the elements  47  and  48  are placed against the outer surface of the element  42 , the elements  50  and  51  are placed against the outer surface of the element  41 . The making of the structural assembly  130  enables upper and lower lengthwise alignments between its elements, which in turn, when two structural elements  130  are placed one on top of the other, enable a fitting between the lower lengthwise edges of the one and the upper lengthwise edges of the other,  FIG. 4   a.  The placing of these elements one on top of the other enables vertical alignment, horizontality, and plumbness.  
         [0035]     The drawing of  FIG. 5  shows a structural assembly  140  consisting of structural elements  140   a,    140   b,    140   c,    140   d,    140   e  and  140   f,  representing a structure in the shape of a cross. According to the invention, the structural element  140   a  consists of a central block  62 , similar to the blocks  63 / 68  and  69 , which is secured to the inner surface of the lateral element  61  on its upper half, and this assembly is secured to the inner surface of the lining element  60 . The structural element  140   b  consists of a central block  77 , having a length greater than that of the block  62 , which is secured to the inner surfaces of the lateral elements  78  and  81  on their lower halves, and this assembly is secured to the inner surfaces of the lining elements  79  and  80 , such that the separation between the elements  80 / 81  and the elements  78 / 79  is at most equal to the thickness of the elements  70 / 71 / 73 / 74  added to that of the block  72 . The structural element  140   c  consists of a central block  63 , which is secured to the inner surface of the lateral element  64  on its lower half and this assembly is secured to the inner surface of the lining element  65 . The structural element  140   d  consists of a central block  68 , which is secured to the inner surface of the lateral element  67  on its upper half and this assembly is secured to the inner surface of the lining element  66 . The element  140   e  consists of a central block  72 , similar to the block  77 , it is secured to the inner surfaces of the lateral elements  73  and  76  on their upper halves and this assembly is secured to the inner surfaces of the lining elements  74  and  75 , such that the separation between the elements  75 / 76  and  73 / 74  is at most equal to the thickness of the elements  66 / 67 / 78 / 79  added to that of the block  68 . The element  140   f  consists of a central block  69 , which is secured to the inner surface of the lateral element  71  on its lower half and this assembly is secured to the inner surface of the lining element  70 . The central blocks  72  and  77  have at the center and located in their bases a recess perpendicular to the respective blocks, with the same profile as the groove and the tongue located at the lower and upper edges of the blocks; these recesses, when assembled, allow one to make an intersecting structure for the structural elements. The component parts of the structural elements  140   a,    140   b,    140   c,    140   d,    140   e  and  140   f,  making up the structural assembly  140 , are placed such that when this structural assembly  140  is produced, the block  72  placed on the block  77  by means of the recess located in the base of the block  72  and mating with the upper tongue of the block  77  are in perpendicular position; the elements  60 / 61 / 66 / 67  and the blocks  62 / 68  are placed against the block  72 ; the block  63  is placed against the block  77 ; the elements  64  and  65  are placed against the outer surface of the element  66 ; the elements  75  and  76  are placed against the outer surface of the element  60 ; the elements  70 / 71 / 73 / 74  and the block  69  are placed against the block  77 ; the elements  78  and  79  are placed against the outer surface of the element  70 ; the elements  80  and  81  are placed against the outer surface of the element  74 . The making of the structural assembly  140  enables upper and lower lengthwise alignments between the elements, which in turn, when two structural assemblies  140  are placed one on top of the other, enables a nesting between the lower lengthwise edges of the one and the upper lengthwise edges of the other,  FIG. 5   a.  The placing of these elements on top of each other enables vertical alignment, horizontality and plumbness.  
         [0036]     The drawing of  FIG. 6  shows, in horizontal top view, the realization of a structure formed overall by several walls and partitions, representing the various construction elements according to the invention.  
         [0037]      FIGS. 6   d,    6   f,    6   c,    6   e  and  6   g  show horizontal top views of the previously described structural construction elements in  FIGS. 1, 2 ,  3   a,    4   a  and  5   a,  respectively.  FIG. 6   b  shows a horizontal top view of:  
         [0038]     two structural assemblies  100  in which the lining element  96  is common to the two assemblies and the lining elements  94  and  95  each belong to one structural assembly  100 , connected together by the profile  97 ,  FIG. 6   a.  The ability to stagger the lining elements, in the case of  FIG. 6   b  the staggering is horizontal, provides more sturdiness to the construction.  
         [0039]     a filler element  90 , which represents for example, a sheet of thermal insulation, which is secured by simple nesting in the cavities  91  located in the lateral ends of the structural assemblies  100 , these cavities  91  are the result of the difference between the lengths of the lateral elements and the lengths of the central blocks, the structural assemblies  110  also have cavities in their lateral ends, which can have the same function.  
         [0040]     two voids  92  and  93 , the void  92  being situated on the exterior side of the construction, enabling a vertical ventilation of the structural elements; this ventilation is also horizontal, by means of the grooves situated in the inner surfaces of the lateral elements and the lining elements  09 ,  FIG. 1 . The void  93  is located at the inner side of the construction, making possible the passage of electricity, water, or other distribution network conduits.  
         [0041]     Another advantage of the invention is the possibility of being able to employ different profiles, as is technically and/or aesthetically necessary, as one can see from  FIGS. 7   a,    7   b,    7   c,    7   d,    7   e  and  7   f.  This possibility of using different profiles in any given element, namely, central block, lateral element, and lining element, provides infinite construction alternatives. It is also possible according to the invention to use lining elements other than wood, as presented in  FIG. 7   d,  where one of the linings consists of a sheet which can be derived from wood or another material.  
         [0042]     The drawing of  FIG. 8  shows a wall section constructed from structural construction assemblies of the invention. In order to achieve the esthetics and rigidity of traditional constructions with staggered courses of brick, it is possible to produce structural construction assemblies  101  having half the length of the structural construction assemblies  102 . These structural assemblies have several advantages, for example:  
         [0043]     they allow the use of several kinds of wood  
         [0044]     they allow the use of small-dimension wood  
         [0045]     they enable, for greater sturdiness of construction, an assembly staggered simultaneously in the vertical plane,  FIG. 8 , and the horizontal plane,  FIG. 6   b,  of these structural construction elements.  
         [0046]     On the other hand, for technical and/or aesthetic reasons, it is also possible to produce structural assemblies of larger dimension, for example having the total length of the wall to be constructed  103 ; this variant has the advantage of eliminating the joints between the lining elements  105 .  
         [0047]     The construction of a wall from structural construction assemblies is easy to implement, simple and within the capability of any amateur. In fact, the phases of construction of the wall section are: 
        arranging the first course of structural construction elements, with the grooves situated in the lower lengthwise edges facing downward, so that the grooves in the lower bases of the central blocks fit together with the upper tongues of the support beams  104 , and the lining elements are joined laterally by the grooves  97 ,  FIG. 6 .     arranging the grooves of the lower lengthwise edges of the structural elements of each upper course so that they fit together with the tongues of the upper lengthwise edges of the structural elements of the next lower course, and the lining elements are joined laterally by the grooves  97 ,  FIG. 6 .        
 
         [0050]     The inserting of the tongues into the grooves enables not just a nesting and stability of the structural elements placed vertically one on top of the other, but also ensures the alignment, the horizontality, and the plumbness of the construction during and after the construction.  
         [0051]     Of course, in order to achieve the junction and the anchoring of the walls to each other, especially in the different directions, as for example those illustrated by  FIG. 6 , where the walls make right angles with each other, one will employ structural construction elements of the invention as previously described. These structural elements will be selected according to the type of construction desired, a L connection, a T connection, a cross connection, a connection with a different angle, etc.  
         [0052]      FIG. 6   h  shows a T-connection of a wall made from structural construction assemblies  100  with another wall of partition type, made from assemblies of structural construction elements  110 . This connection uses a lath  98 , having the same width as the thickness of the central block of the elements  110 , which is secured vertically on the outer surface of the wall made with the assemblies of elements  100 , after putting in place of this lath  98 , the other wall is attached by fitting the lining elements of the structural assemblies  110  to the lath; the sides of the lath rest against the inner surfaces of the lining elements of the structural assemblies  110 .  
         [0053]     The connection and fixation of the structures made from the construction elements of the invention are assured by elements placed in the vertical openings located in the central blocks of the construction elements, for example, screw spindles with supplemental accessories such as washers, bolts, connectors, etc.  
         [0054]     It is understood that the structural construction elements described and represented above have been done so by way of a disclosure, rather than a limitation. Obviously, improvements, adjustments and modifications could be made to the preceding examples, without thereby leaving the scope of the invention, taken in its broadest spirit and aspects. Thus, for example, the dimensions of the component parts of the structural elements which have been described above, namely, the central block having half the useful height of the lateral element, and the latter having the same useful height as the lining element, certainly can be modified without leaving the original and innovative concept of the invention; on the other hand, the structures which have been described as being those of walls or partitions certainly can be implemented to produce ceilings, floors, etc.

Summary:
A system of structural wood elements has blocks that have grooves on bases and tongues on tops for superimposing the blocks. A lateral element fixed to one side of the blocks is thinner and longer than the blocks. Opposite ends of the lateral element are fixed to the topmost top and bottommost base of the blocks
