Description

The invention relates to the general field of building materials and associated building methods of walls, for the purpose of erecting a building, such as a residential building, or a pool. pool, temporarily or permanently.

The invention relates more specifically to a system for constructing a wall, in particular for a building, the building system comprising: at least one first wall panel having a first edge defining a length of the first wall panel; at least one second wall panel having a second edge defining a length of the second wall panel, the first wall panel and the second wall panel being intended to be arranged in a wall construction arrangement, in which they are placed opposite one of the another to define between them a filling space in which a filling material is intended to be introduced to form said wall with said first wall panel and said second wall panel, - at least one spacer designed to hold the first wall panel and the second wall panel in their building arrangement, the spacer comprising: o a first end of mounting the spacer on the first edge of the first wall panel, and o a second mounting end of the spacer on the second edge of the second wall panel. The invention also relates to a wall construction spacer, in particular for a building, the spacer being adapted to hold a first wall panel, having a first edge defining a length of the first wall panel, and a second wall panel having a second edge defining a length of the second wall panel, in a building arrangement of said wall in which the first wall panel and the second wall panel are placed opposite one another to delimit between them a filling space in wherein a filler material is to be introduced to form said wall with said first wall panel and said second wall panel, said spacer comprising: - a first mounting end of the spacer on the first edge of the first wall panel, and - a second mounting end of the spacer on the second edge of the second wall panel. The invention further relates to a wall, preferably a building. The invention finally relates to a method of constructing a wall, in particular for a building, comprising the following steps: at least one first wall panel having a first edge defining a length of the first wall panel is provided, and on the other hand at least one second wall panel having a second edge defining a length of the second wall panel, according to a wall construction arrangement in which the first wall panel and the second wall panel are placed opposite one of the other to define a filling space between them, - said first wall panel and said second wall panel are maintained in their construction arrangement by means of at least one spacer, by mounting a first mounting end of the spacer on the first edge of the first wall panel, and a second end mounting the spacer on the second edge of the second wall panel, - it is introduced a filling material in the filling space thus delimited to form said wall with said first wall panel and said second wall panel. We know a system of construction of buildings, such as houses, especially to erect the walls of said buildings. The building system comprises in particular expanded polystyrene wall panels, generally rectangular in shape, and each delimited by four sides forming the edge of the panel. During the construction of a portion of the wall, a first panel is placed in front of a second panel, so that said panels are arranged vertically opposite one another in a substantially parallel manner, and rest on one of their respective sides, to provide a substantially parallelepiped space between them, in which is poured concrete to form the core of the wall. The panels of the building system thus accumulate the role of formwork formwork concrete and means of thermal insulation and / or sound of the wall. This known construction system makes it possible to provide good insulation to the building constructed, good strength, and easy assembly, especially since it is not necessary to provide a temporary binder to form the concrete.

In this known construction system, before pouring concrete in the space between the panels, it is necessary to keep them in place. The known construction system thus includes spacers holding the panels facing each other, the spacers being adapted to be attached to said panels through the upper side thereof.

The respective upper sides of each panel have a longitudinal groove in which a longitudinal rail of the spacers is provided to be inserted to attach the spacer to said sides. In addition, the respective upper sides of each panel also have a plurality of transverse slots distributed over the entire length of the side, and spaced for example 5 cm (centimeters) each, to accommodate transverse crosspieces spacers that connect the two longitudinal rails of these last ones between them. Generally, each pair of panels can thus accommodate along the upper side of each panel a group of three spacers designed to hold them in position. Although this construction system is generally satisfactory, it nevertheless has some characteristics that could be improved. In particular, the positioning of the spacers on the side of said panels is limited, because of the spacing of the slots, to a number of distinct locations, for example every 5 cm. Therefore, it may be difficult, if not impossible, to meet certain dimensional constraints of construction, especially when the dimensions planned for the construction are not multiples of 5 cm. It is then most often necessary to make a manual cut of spacers and / or panels, which is a waste of time, and it is not always easy to perform precisely given the materials used. Indeed, it is most often necessary to use for example a wire cutting instrument to cut the expanded polystyrene panels, a simple saw usually does not offer the necessary accuracy. The expanded polystyrene forming the panels is generally chosen graphite, so that it presents a good compromise between mechanical strength and property of thermal insulation of the building. However, in some cases, graphite polystyrene has a relatively high deformability, especially under the influence of factors such as humidity, temperature, and solar radiation (especially since the presence of graphite gives an anthracite color or black to the material), so compliance with construction ratings may be affected in some cases. In particular, the slots of a given panel may be deformed, or offset, with respect to the slots of a second panel, so that it may no longer be possible to set up the support spacers on the sides of the panels. two panels at a time, without making a manual retouch of the shape of the panels or spacers, which is an additional operation and a waste of time. In addition, the influence of sunlight can sometimes have a detrimental impact on the bonding properties of expanded polystyrene, so that its ability to receive an external coating can be affected. If the use of a light-colored, for example white, polystyrene, can mitigate the influence of solar rays, this material nevertheless offers poorer thermal insulation properties of the building.

Furthermore, the known panels have a relatively complex shape, especially given the need to provide both regularly spaced slots and grooves at the sides, which requires means of manufacturing panels adapted and relatively complex . As a result, the cost price of the panels can be relatively high.

Finally, the mutual shape of the crenels and spacers allows to arrange the latter only so that they are spaced apart from each other along the side. In particular, each spacer will be separated from an inter-slot gap of at least 5 cm. In certain situations, it is necessary to install elements screwed into the panels. To ensure the safety of screwing, it is generally desirable to make it through the panel, and into the rail of the spacer inserted in the groove, so that the threads of the screw find a sufficiently strong support. The spacers being spaced longitudinally, it is necessary to ensure that the screwing is not performed in this inter-spacer space, which can be a constraint for implementation in terms of dimensions. In addition, it can sometimes be difficult to estimate the position of inter-spacing spaces when they are for example covered with concrete, or hidden by a panel used for the erection of the wall. The objects assigned to the invention therefore aim to remedy the various drawbacks enumerated above and to propose a new system and a new method of constructing a wall that allow a quick, easy and practical construction of said wall, with human resources. and relatively small equipment.

Another object of the invention is to propose a new system and a new method of building a wall, imparting particularly high thermal and acoustic insulation properties to said wall.

The objects assigned to the invention are also achieved by means of a wall construction spacer, in particular for a building, the spacer being designed to hold a first wall panel, having a first edge defining a length of the first wall panel, and a second wall panel having a second edge defining a length of the second wall panel, in a building arrangement of said wall in which the first wall panel and the second wall panel are placed opposite one of the another for defining between them a filling space in which a filling material is intended to be introduced to form said wall with said first wall panel and said second wall panel, said spacer comprising: - a first mounting end of the spacer on the first edge of the first wall panel, and - a second mounting end of the spacer on the second edge of the uxth wall panel, said spacer being characterized in that the first mounting end is shaped to form a mounting link, with the first edge, so that said mounting link, while allowing the maintenance of the first wall panel and the second wall panel in their construction arrangement, allows a travel stroke of the spacer in the direction of the length of the first wall panel along said first edge, so that the position of the spacer along said first edge is adjustable according to an infinity of distinct positions of the spacer along said first song. The objects assigned to the invention are furthermore achieved by means of a wall, preferably a building, characterized in that it is constructed using the construction system of the invention, said wall comprising at least the first wall panel and the second wall panel of the building system, which are held in the building arrangement by the spacer, so that the filling space is provided between said first wall panel and said second panel wall, said wall also comprising a filling material, such cement or concrete, introduced into the filling space.

Other advantages and objects of the invention will appear in more detail on reading the description which follows, and with the aid of the accompanying drawings provided for purely explanatory and non-limiting purposes in which: FIG. perspective view, a construction system according to the invention. FIG. 2 illustrates, in a cross-sectional view, the construction system of FIG. 1. FIG. 3 illustrates, in a perspective view, a first preferred variant of a spacer belonging to the construction system of FIG. 1. - Figure 4 shows, in a perspective view, a second preferred embodiment of a spacer according to the invention. - Figure 5 illustrates, in a perspective view, a third preferred embodiment of a spacer according to the invention. FIGS. 6 and 7 show, respectively in a perspective view and in a front sectional view, a corner piece preferably belonging to the construction system of FIGS. 1 and 2. FIG. 8 illustrates, in a view in partial cross-section, an embodiment detail of the construction system of FIGS. 1 and 2. The invention relates, as such, to a system for constructing a wall, a preferred embodiment of which is illustrated in FIGS. 2. The construction system of the invention makes it possible in particular to construct a wall, that is to say a solid wall, in particular for a building of the type house, cabin, shelter, garage or building, or alternatively for any another structure built with walls, for example a swimming pool, a pond, a cellar, an enclosure, etc. The wall constructed using the construction system of the invention is preferably intended to be placed outside, but may alternatively form a partition wall inside a structure. The wall built is preferably a load-bearing wall, but nothing prevents it from being used as a simple wall. The constructed wall is preferably a permanent construction, but can however be used as a temporary construction.

The wall obtained using the construction system is preferably composed of several layers, as described below. As illustrated in FIGS. 1 and 2, the construction system of the invention comprises at least a first wall panel 11, which is preferably of generally rectangular or parallelepipedal general shape, with a thickness E1, a length Li (for example between approximately 50 cm and 200 cm, preferably 120 cm), and a height H1 (for example between about 15 cm and 100 cm, preferably 30 cm). The first wall panel 11 is advantageously intended to form one of the layers of the wall, the thickness E1 being parallel to the thickness of the wall. Thus, preferably, the first wall panel 11 is intended to be disposed substantially vertically: for example so that its length L1 is substantially vertical and its height H1 is substantially horizontal, or for example so that that its height H1 is substantially vertical and its length Li is substantially horizontal. Thus, the first wall panel 11 preferably has, on each side of the thickness E1, an outer face 111 intended to be oriented towards the outside of the wall, and an inner face 112 opposite intended to be oriented towards the inside of the wall. . Preferably, the first wall panel 11 is intended to form an insulation layer of the wall, for example thermal or acoustic. For this, all or part of the first wall panel 11 is advantageously made of extruded polystyrene, which is relatively insensitive to the influence of climatic elements such as solar rays, moisture and temperature variations, while ensuring good insulation of the wall, and possibly of the construction that the wall delimits. Preferably, the first wall panel 11 comprises an extruded polystyrene core, advantageously extending over the majority of the thickness E1 of said first wall panel 11, that is to say between the outer face 111 and the inner face 112 of said first wall panel 11. Preferably, the first wall panel 11 also comprises an outer coating extending over a portion of the thickness E1 between the core and the outer face 111, preferably made of a material different from that of the core, for example polyurethane, in particular to improve the insulating effect and protect the soul of the above-mentioned climatic conditions. The first wall panel 11 also preferably comprises an inner coating which extends over a portion of the thickness E1 between the core and the inner face 112, and which is advantageously made of a material different from that of the core, for example polyurethane, or aspenite (also called "Oriented Chipboard" or "OSB"). Of course, other materials may be envisaged to form the first wall panel 11. In particular its core, or even the entire first wall panel 11, may be made of expanded polystyrene, polystyrene graphite, or polyurethane. Nevertheless, particularly preferably, the inner lining of the first wall panel 11 is made of aspenite, its core is made of extruded polystyrene, and the filling material is formed by concrete, which in particular gives the wall insulation properties. particularly high temperatures.

According to the invention, the first wall panel 11 has a first edge 113, which defines the length L1 of the first wall panel 11, that is to say which is substantially oriented in the same direction as said length L1. Thus, the first edge 113 preferably has a width equal to the thickness E1, and is advantageously of length Li, the length Li being greater than the thickness E1. The first edge 113 advantageously forms the edge of the first wall panel 11, c preferably one side connecting the outer face 111 to the inner face 112 in the direction of the thickness E1. The first wall panel 11 advantageously has three other edges to form the parallelepipedal general shape of said first wall panel 11 with the outer face 111 and the inner face 112, including a recess edge 114, preferably opposite the first edge 113, the first wall panel 11 being intended to rest on the edge recess 114 when the wall is built. Of course, the first wall panel 11 may also rest on the first edge 113 when the wall is built.

Preferably, the first edge 113 is substantially straight, that is to say rectilinear. It may nevertheless have curvatures along the length Li, especially in the case where the first wall panel 11, and / or the wall to be constructed have a non-planar shape. According to the invention, the construction system also comprises a second wall panel 12, which is advantageously separate from the first wall panel 11. The second wall panel 12 is preferably identical to the first wall panel 11, or at least similar to the extent that it comprises for example elements with the same function, or identical to those of the first wall panel 11. The geometry of the second wall panel 12 is preferably similar or identical to that of the first wall panel 11. However, in particular to respect the constraints geometric final wall, the second wall panel 12 may be of different dimensions than those of the first wall panel 11. Given this, the second wall panel 12 is preferably substantially rectangular or parallelepiped general shape, with a thickness E2, 30 a length L2 (for example between about 50 cm and 200 cm, preferably 120 cm), and a height H2 (for example between about 15 cm and 100 cm, preferably 30 cm). The second wall panel 12 is advantageously intended to form one of the layers of the wall, the thickness E2 being parallel to the thickness of the wall. Preferably, either the height H1 is equal to the height H2, or the length L1 is equal to the length L2. Preferably, the heights H1, H2 and the lengths L1, L2 are two by two. Thus, preferably, the second wall panel 12 is intended to be arranged substantially vertically: for example so that its length L2 is substantially vertical and its height H2 is substantially horizontal, or for example so that that its height H2 is substantially vertical and its length L2 is substantially horizontal. Thus, the second wall panel 12 preferably has, on each side of the thickness E2, an outer face 121 intended to be oriented towards the outside of the wall, and an opposite inner face 122 intended to be oriented towards the first wall panel 11 when the wall is built. Preferably, the second wall panel 12 is intended to form an insulation layer of the wall, for example thermal or sound. For this, all or part of the second wall panel 12 is advantageously made of extruded polystyrene. Preferably, the second wall panel 12 comprises an extruded polystyrene core, preferably extending over most of the thickness E2 of said second wall panel 12, i.e., between the outer face 121 and the inner face 122 of said second wall panel 12. Preferably, the second wall panel 12 also comprises an outer coating extending over a portion of the thickness E2 between the core and the outer face 121, preferably made of a material different from that of the core, for example polyurethane, in particular to improve the insulating effect and protect the soul of the above-mentioned climatic conditions. The second wall panel 12 also preferably comprises an inner coating which extends over a portion of the thickness E2 between the core and the inner face 122, and which is advantageously made of a material different from that of the core, for example polyurethane, or aspenite. Of course, other materials may be considered to form the second wall panel 12. In particular its core, or even the entire second wall panel 12, may be made of expanded polystyrene, polystyrene graphite, or polyurethane. Nevertheless, particularly preferably, the inner lining of the second wall panel 12 is made of aspenite, its core being made of extruded polystyrene. Thus, the thermal insulation properties of the wall are further improved, in particular in combination with the inner lining of the first wall panel 11 which is made of aspenite, its core being made of extruded polystyrene, and the filling material being formed by concrete . The second wall panel 12 of the invention has a second edge 123, which defines the length L2 of the second wall panel 12, that is to say which is substantially oriented in the same direction as said length L2. Thus, the second edge 123 preferably has a width equal to the thickness E2, and is advantageously of length L2, the length L2 being greater than the thickness E2. The second edge 123 advantageously forms the edge of the second wall panel 12, that is to say preferably a side connecting the outer face 121 to the inner face 122 in the direction of the thickness E2. The second wall panel 12 advantageously has three other edges to form the parallelepipedal general shape of said second wall panel 12 with the outer face 121 and the inner face 122, including a rest edge 124, preferably opposite the first edge 113, the second panel wall 12 being intended to rest on its own song of rest 124 when the wall is built. Of course, the second wall panel 12 may also rest on the second song 123 when the wall is built. Preferably, the second edge 123 is substantially straight, that is to say rectilinear. It may nevertheless have curvatures along the length L2, particularly in the case where the second wall panel 12, and / or the wall to be constructed have a non-planar shape.

The first wall panel 11 and the second wall panel 12 are thus preferably of generally rectangular shape, the first edge 113 forming one of the sides of the rectangular shape of the first wall panel 11, and the second edge 123 advantageously forming one of the the sides of the rectangular shape of the second wall panel 12. In the following, the first edge 113 and the second edge 123 advantageously form (as illustrated in FIGS. 1 and 2), the respective upper edge of the first wall panel 11 and the second wall panel 12. However, the first song 113 and the second song 123 may designate the respective lower edge of the first wall panel 11 and the second wall panel 12, or one of the respective side edges of the latter. According to the invention, as illustrated in Figure 2, the first wall panel 11 and the second wall panel 12 are intended to be arranged in a wall construction arrangement, in which they are placed opposite one of the 'other. The first wall panel 11 and the second wall panel 12 are thus advantageously intended to be placed at a distance from each other, opposite, and for example substantially parallel to each other, and preferably so substantially vertical. Of course, the building arrangement may alternatively correspond to a provision according to which the first wall panel 11 and the second wall panel 12 are not parallel, but instead form an angle, so as to form a wall of non-constant thickness on the wall. length of the latter. The first wall panel 11 and the second wall panel 12 are thus preferably intended to be arranged on the edge to form the wall, and for example on the basis of foundations, a slab preferably made of concrete, or excavations. Alternatively, the first wall panel 11 and the second wall panel 12 may be arranged on the basis of a pair of similar, similar wall panels, to form a wall by stacking pairs of similar wall panels, as described below. In their arrangement of construction, the first wall panel 11 and the second wall panel 12 of the invention delimit between them a filling space 20 in which a filling material 21 is intended to be introduced to form said wall with said first wall panel 11 and said second wall panel 12. Thus, the first wall panel 11 and the second wall panel 12 are arranged to form a formwork for the filling material 21, which is preferably designed to come into contact with each of said wall panels 11 , 12, and optionally. The first wall panel 11 and the second wall panel 12 thus preferably combine the role of thermal and / or sound insulation for the wall, and the role of molding means for the core of the wall formed by the filling material 21. The latter advantageously confers mechanical strength and longevity to the wall. The filling material 21 may advantageously form a cement, or preferably a concrete, advantageously ironed. The filling material 21 is advantageously intended to be poured into the filling space 20, for example in order to partially or even substantially fill said filling space 20. Of course, depending on the constraints imposed by the construction, another material filling 21 may be implemented, for example plaster. The filling space 20 may for example measure a thickness of between 10 and 50 cm, depending on the type of construction to be made, and preferably about 16 cm. The filling space 20 thus preferably forms a parallelepipedal volume, closed on its two longitudinal sides by the first wall panel 11 and the second wall panel 12. The construction system may also comprise at least one side panel (not shown), designed to be attached and fixed, for example by screwing, so as to connect the first wall panel 11 to the second wall panel 12, to close said filling space 20 on a transverse face thereof. The side panel advantageously comprises an aspenite layer intended to be oriented towards the outside of the wall, and a layer of insulation, for example thermal and / or phonic, in contact with the aspenite layer, and preferably intended for be turned towards the filling space 20, for example to be in contact with the filling material 21. The side panel may thus preferably form an end of the wall, or a framing member of an opening of the wall of the kind window or door, preferably a lintel, a support, or a side table of said opening of the wall.

Preferably, the side panel is designed to be attached to the filling material 21, for example by screwing. Alternatively, the side panel can be fixed, for example by screwing, to the first wall panel 11 and / or the second wall panel 12.

The building system of the invention also includes at least one spacer 30 designed to hold the first wall panel 11 and the second wall panel 12 in their building arrangement, the spacer 30 of the invention also being subject to protection as such. Three examples of spacers 30 according to the invention are illustrated separately from the construction system of the invention in FIGS. 3 to 5. The spacer 30 allows, according to the invention, to fasten, or at least to stall, the first wall panel 11 and the second wall panel 12, so that they retain their construction layout. In particular, the spacer 30 makes it possible to prevent said wall panels 11, 12 from tipping, for example under their own weight, and also makes it possible to preferably retain said wall panels 11, 12 in their construction arrangement when these are subjected to possible pressures caused by the filling material 21, for example where the latter would be introduced into the filling space 20 in the liquid state. As illustrated for example in Figures 1 to 5 and 8, the spacer 30 of the invention comprises a first mounting end 31 of the spacer 30 on the first edge 113 of the first wall panel 11, and a second end of assembly 32 of the spacer 30 on the second edge 123 of the second wall panel 12. The spacer 30 is thus designed to be attached firstly to the first edge 113 and secondly to the second edge 123, by the intermediate respectively the first mounting end 31 and the second mounting end 32 to connect the first wall panel 11 and the second wall panel 12 and keep them in their building arrangement. In the manner of a template, the spacer 30 also preferably ensures that the spacing between the first wall panel 11 and the second wall panel 12 is correct, and that the positioning of the latter, in general, corresponds well to the construction layout described above. The spacer 30 advantageously forms a bridge connecting the first wall panel 11 and the second wall panel 12 between them, via one of their respective edge, preferably the first edge 113 and the second edge 123, which are placed opposite each other. The spacer 30 thus preferably allows to put, and maintain, in their mounting arrangement, the first wall panel 11 and the second wall panel 12, which allows in particular to limit the number of measurement operations for the construction of the wall . Preferably, the spacer 30 is intended to be permanently installed in the wall, in particular to the extent that the filling material 21 is capable of covering said spacer 30 once inserted into the filling space 20. The spacer 30 may of course nevertheless be used as a temporary positioning element of the first wall panel 11 and the second wall panel 12. According to the invention, the first mounting end 31 and the first edge 113 are shaped to form a mounting link which, while allowing the maintenance of the first wall panel 11 and the second wall panel 12 in their construction arrangement, allows a travel stroke of the spacer 30 in the direction of the length L1 of the first wall panel 11 along said first edge 113, so that the position of the spacer 30 along said first edge 113 is adjustable in an infinity of distinct positions of the spacer 30 along said first edge 113. The mounting connection formed by the first edge 113 and the first mounting end 31 thus advantageously makes it possible to secure the first wall panel 11 and the spacer 30 in order to block their movement in the transverse directions to said edge, so that the spacer 30 can retain any tilting, or displacement, of the first wall panel 11 to the inside or outside of the wall, while nevertheless allowing preferably the relative movement of the spacer 30 relative to the first wall panel 11 along the first edge 113. Preferably, the spacer can be moved along the first edge 113, which forms the travel stroke of the spacer 30. Advantageously, the spacer 30 may be designed to slide along the first edge 113. However, preferably, the spacer 30 is designed to require to be first disconnected from u first edge 113 to then be repositioned to any desired coordinate along the first edge 113, the formed mounting link is not slidable along the first edge 113. The spacer 30 of the invention can therefore be fixed to the first wall panel 11 so as to be positioned indifferently along the first edge 113, in a continuous range of possible distinct positions along the edge. The wall construction system and its spacer 30 targeted by the invention are particularly versatile, and allow in particular to build a wall of all dimensions, with relatively limited human and material resources. Indeed, the spacer 30 can be placed at any desired location along the wall, which makes the building system quite adaptable to any situation, and the constraints inherent to the erection of a wall, they are expected or unexpected. In particular, thanks to such a design, it is most often not necessary to retouch the spacers 30 and the first and second wall panels 11, 12 on the construction site of the wall, to the extent that their relative placement can be Customized according to the situation. Preferably, likewise, the second mounting end 32 and the second edge 123 are shaped to form a mounting link which, while allowing the first wall panel 11 and the second wall panel 12 to be held in their building arrangement, allows a travel stroke of the spacer 30 in the longitudinal direction L2 of the second wall panel 12 along said second edge 123, so that the position of the spacer 30 along said second edge 123 is adjustable in an infinity of separate positions of the spacer 30 along said second edge 123. Thus, it is preferably possible to freely position the spacer 30 at any desired position in the direction of the length of the wall, insofar as both the first panel wall 11 and the second wall panel 12 allow that any position of the spacer along their first and second singing 113, 123 is adopted. Any planned dimension for the wall can thus advantageously be achieved using the construction system.

The spacer 30 is preferably made of polymer, for example polypropylene, which gives it rigidity and lightness. Alternatively, the spacer 30 may for example be made of metal. Preferably, in order to obtain such a mounting connection of the spacer 30 on the first wall panel 11, the first edge 113 of the first wall panel 11 comprises a first groove 115, which is arranged so as to extend into the direction of the length L1 of said first edge 113. The first groove 115 preferably forms a rectilinear groove, which extends parallel to the edges of the first edge 113, preferably all along said first edge 113. The spacer 30 comprises as it preferably a first blade 33 which forms the first mounting end 31, and which is intended to be inserted into the first groove 115 of the first wall panel 11 in order to attach the spacer 30 to said first wall panel 11. The first blade 33 is therefore preferably geometrically corresponding with the first groove 115, so as to form between them an interlocking, or at least a hook, of the spacer 30 on the first 113. The first groove 115 thus preferably forms a rail for the first blade 33. The shape of the first groove 115 and the first blade 33 advantageously make it possible: - either for example to said first blade 33 to be able to slide in said first groove 115 along the first edge 113 so that the spacer 30 can be positioned, and possibly repositioned, at the desired location along the first edge 113, possibly without having to be out of the first groove 115, or for example to said spacer 30 can be mounted indifferently to any desired location along the first edge 113 in the first groove 115, the mounting being for example sufficiently tight, rubbing or adherent to substantially limit any movement of the first blade 33 along of the first edge 113 when said first blade 33 is inserted into the first groove 115.

The first crosspiece 35 preferably forms an elongated and substantially rigid element, of the rod, beam or batten type , making it possible to keep at a distance, or at least to help maintain, at a distance, the first wall panel 11 and the second wall panel 12, and more particularly in their wall construction arrangement. The first crossbar can be of any shape. However, over at least a portion of its length, at least at its ends, the first crosspiece 35 is preferably of flat shape, or even has a flat profile, for example an "I" section. The first crosspiece 35 preferably comprises a reinforcing rib 38, in particular to improve the buckling resistance of said crossmember 35, and so as to present, on an intermediate portion of the length of said crossmember, a cross-section for example in "T" shape. Or in "". Preferably, the first blade 33 extends in a longitudinal direction of the spacer 30, and forms an extension surface from which said first crosspiece 35 projects. The longitudinal and transverse directions of the spacer 30 thus defined are preferably orthogonal, so in particular that the first crosspiece 35 is preferably orthogonal to the first blade 33 and its yaws extension. The first blade 33 preferably comprises a first longitudinal edge 39 and a second longitudinal edge 40, extending substantially in the longitudinal direction and delimiting the extension surface of the first blade 33. The first longitudinal edge 39 is preferably rectilinear on at least the majority of its length, indeed over its entire length, and is preferably parallel to the second longitudinal edge 40, which is advantageously itself rectilinear. Consequently, the first blade 33 preferably forms a solid of generally elongate and for example substantially rectangular shape, the rectangular extension surface thus formed being preferably substantially full, if not completely full. The shape of the first blade 33 allows it in particular to accommodate any screws 42, which could be fixed through both the first wall panel 11 and the first blade 33, for example to fix elements to the wall, such as brackets, preferably temporary, for adjusting the inclination of the first wall panel 11. The solid and continuous nature of the first blade 33 advantageously allows when a screw is inserted in the first wall panel 11 to near the first edge 113, to fall surely on the first blade 33, which forms a reliable and solid element for screwing the screw 42. Preferably, the spacer 30 is designed to bear on the first song 113: for example by means of the first blade 33, regardless of the entire length of the first groove 115, said first blade 33 then being for example supported on the bottom of the first groove 115, and / or - for example via the first crosspiece 35, regardless of the entire length of the first groove 115, the first crosspiece 35 then preferably bearing on the first song 113. Preferably, the first song 113 comprises a first edge surface 116 extending along at least a majority of the length of the first groove 115. The first edge surface 116 advantageously connects the first groove 115 to the edge of the first edge 113, on the the filling space 20, that is to say preferably up to the inner face 112 of the first wall panel 11. The first crosspiece 35 preferably comprises a substantially plane end portion 41 of the crosspiece extending from the first blade 33, and which is oriented so that, when the first blade 33 is inserted into said first groove 115, the spacer 30 bears on the first edge surface 116 d u first wall panel 11: - preferably, through the first blade 33, said end portion of crosspiece 41 extending substantially parallel to the first edge surface 116, and / or - for example by the intermediate of said end portion of cross member 41, the latter lying flat on said first edge surface 116. Thus, the end portion of cross member 41 preferably extends in a longitudinal plane of the spacer 30. Preferably, the first crosspiece 35 extends in a plane oriented in the longitudinal direction and in the transverse direction of the spacer 30, this plane being advantageously parallel to the first edge 113 when the spacer 30 is mounted on the latter.

For example, the first edge surface 116 is substantially flat. In particular, the first edge 113 preferably allows free translation along the first edge 113 of the first crosspiece 35.

Preferably, the spacer 30 comprises several crosspieces 35, 36, 37 identical to the first crossmember 35, or at least of construction and similar geometry, which each connect the first blade 33 to the second mounting end 32, in order to maintain at a distance the first wall panel 11 and the second wall panel 12, and more particularly in their wall construction arrangement. As illustrated in the figures, the spacer 30 comprises for example the first crossmember 35, a second crossmember 36 and a third crossmember 37, which are preferably substantially identical and parallel to each other. Preferably, the crosspieces 35, 36, 37, whatever their number, project from the first blade 33 along a common imaginary line, intended to be parallel, or merged, with the first edge 113 of the first wall panel 11 The number of crosspieces 35, 36, 37 can of course be adapted according to the mechanical stresses to be applied to the spacer 30, and in order to generate the best possible compromise between mechanical strength, mass of the spacer and cost of the latter. .

Preferably, the second edge 123 of the second wall panel 12 comprises a second groove 125, which is arranged so as to extend in the direction of the length L2 of said second edge 123. The second groove 125 preferably forms a rectilinear groove , which extends parallel to the edges of the second edge 123, preferably all along said second edge 123. The spacer 30 advantageously comprises a second blade 34 which forms the second mounting end 32, and which is intended to to be inserted in the second groove 125 of the second wall panel 12 in order to attach the spacer 30 to said second wall panel 12. The second blade 34 is therefore preferably geometrically corresponding with the second groove 125, so as to form between them a nesting, or at least one hook, of the spacer 30 on the second edge 123. The second groove 125 thus preferably forms a rail for r the second blade 34. The shape of the second groove 125 and the second blade 34 advantageously allow: either for example to said second blade 34 to be able to slide in said second groove 125 along the second edge 123 so that the spacer 30 can be positioned, and possibly repositioned, at the desired location along the second edge 123, possibly without having to be out of the second groove 125, for example to said spacer 30 to be mounted indifferently to any desired location along the second edge 123 in the second groove 125, the assembly being for example sufficiently tight, rubbing or adherent to substantially limit any movement of the second blade 34 along the second edge 123 when said second blade 34 is inserted into the second groove 125.

Preferably, the second blade 34 is of identical length to the first blade 33 and has characteristics and a similar geometry, or even identical to the latter. Preferably, the first wall panel 11 and the second wall panel 12 are identical, and are mirrored from each other in their wall construction arrangement. Preferably, the first crosspiece 35 projects from the first blade 33, and more particularly from the extension surface thereof, from the second longitudinal edge 40 of the extension surface, so that the first end of assembly 31 has an "L" configuration (as shown in FIG. 4). In this preferred configuration, the first cross member 35 and the first blade 33 advantageously form a bend, or a fold, so that the first blade 33 preferably projects only on one side of the first cross member 35. In this configuration, the section of the spacer 30, in a plane orthogonal to the longitudinal direction of the spacer 30, has locally an "L" shape at the connection between the first blade 33 and the first cross member 35. The second longitudinal edge 40 thus preferably forms the physical connection between the first cross-member 35 and the first blade 33. Thus, when the first blade 33 is inserted into the first groove 115, it is almost entirely included in said first groove 115, so as not to , or slightly exceed the first song 113. The spacer 30 being inserted into the first edge 113, in this preferred configuration, the first crosspiece 35 and the The edge 113 preferably forms a substantially planar surface on which the first wall panel 11 may for example rest, or on which an element may be attached, such as, for example, a roof, a floor, a lintel or a window sill.

In the example of FIG. 2, the first wall panel 11 rests on its rest edge 114, which is in accordance with the description that was made above of the first edge 113, and comprises a rest groove 117 preferably similar to the first groove 115, wherein the first blade 33 of a spacer 30 is inserted, the first mounting end 31 of said spacer 30 having an "L" configuration as defined above. In this example, the first wall panel 11 thus rests on the substantially flat surface formed by its edge recess 114, and the spacer 30 which is mounted on said recline 114. The first wall panel 11 preferably rests on a slab concrete, or on excavations, through said reclining edge 114, the spacer 30 being secured, for example by screwing, with said excavation or with said concrete slab. Alternatively, the first cross member 35 projects from the first blade 33, and more particularly from the extension surface thereof, between the first longitudinal edge 39 and the second longitudinal edge 40 of the extension surface, preferably mid-way, so that the first mounting end 31 has a "T" configuration (as shown in Figure 3). In this preferred configuration, the first blade 33 protrudes on either side of the first crosspiece 35, and in particular the first longitudinal edge 39 and the second longitudinal edge 40 protrude on either side of the first crosspiece 35. In this configuration, the section of the spacer 30, in a plane orthogonal to the longitudinal direction of the spacer 30, locally has a "T" shape at the connection between the first blade 33 and the first cross member 35. .

The first mounting end 31 having a "T" configuration, as described above, the building system preferably comprises a third wall panel 13 comprising a third edge 133 defining a length L3 of the third wall panel 13 and comprising a third groove 135 which is formed along the length L3 of the third wall panel 13.

Preferably, the wall panels 11, 12, 13 are similar, or even identical, and each conform to the description of the first wall panel 11 above. Similarly, the spacers 30 are preferably similar, or even identical, and each conforms to the foregoing description. Preferably, the construction system comprises several spacers 30 substantially identical, the length of the first edge 113 of the first wall panel 11, in the lengthwise direction L1, being equal to a multiple of the length of the first blade 33 of said spacers According to this advantageous configuration, the spacers 30 can be mounted along the first edge 113 so that their first blades 33 are in contact with each other, edge to edge, at their ends. The addition of the length of the first blades 33 is advantageously equal to the length L1 of the first wall panel 11, and preferably equal to the length of the first groove 115. Thus, the entire length of the first groove 115 is advantageously filled by one of the first blades 33, so that screws 42 may for example be screwed into the first wall panel 11, in the vicinity of the first groove 115, through said first blades 33, along the entire length L1 of the first wall panel 11.

In order to obtain a similar effect, it is possible to envisage that the length of the first blade 33 of the spacer 30 is equal to, or greater than, the length L L, and preferably that of the first groove 115. For example, the length L1 is 125 cm, and the length of the first blade 33 is 75 cm. The second mounting end 32 advantageously has itself a "T" configuration or an "L" configuration, so that it is possible to obtain three different variants of struts 30: a first variant, in which the first mounting end 31 and the second mounting end 32 both have a "T" configuration (as shown for example in FIG. 3), a second variant in which the first mounting end 31 and the second mounting end 32 both have a "L" configuration (as illustrated, for example, in FIG. 4), a third variant, in which the first mounting end 31 and the second mounting end 32 present a configuration different from each other, one presenting in this case an "L" configuration, and the other presenting in this case a "T" configuration (as illustrated, for example in Figure 5). Preferably, the first mounting end 31 of the spacer having a "T" configuration, as illustrated in FIGS. 1 and 8, the third wall panel 13 is intended to be stacked on the first wall panel 11 by the intermediate of their respective first song 113 and third song 133 to help build said wall.

In this configuration, the third wall panel 13 rests on the first wall panel 11 via their respective first edge 113 and third edge 133, which are preferably in direct contact with one another, or for example via a gasket or a gasket. glue. The filling material 21 can thus fill the filling space 20 formed by the combination of the first, second, third and fourth wall panels 11, 12, 13. The combination of the first wall panel 11 and the third wall panel 13 preferably forms a layer of insulation, for example heat, of the wall, the combination of the second wall panel 12 with the fourth wall panel also forming a layer of insulation, for example thermal, of the wall.

In this preferred configuration of stacking the third wall panel 13 on the first wall panel 11, the first blade 33 is consequently inserted firstly into the first groove 115 via its first longitudinal edge 39, and on the other hand in the third groove 135 via its second longitudinal edge 40. The spacer 30 thus advantageously makes it possible to keep the first wall panel 11 and the third wall panel 13 in the building arrangement. preferably protruding from the insulation layer formed by the combination of the first wall panel 11 and the third wall panel 13. As can be seen for example in Figures 1, 2 and 8, advantageously, the first edge surface 116 is recessed to form with the third song 133 a clearance groove 43 of the first cross member 35 (and preferably any second and third transverse members 36, 37) along the first edge 113, preferably along the entire length thereof.
