Description

Objet de l'inventionObject of the invention

La présente invention concerne le domaine de la construction d'un édifice, et se rapporte à un ensemble d'armatures comprenant une armature de liaison de parois d'un mur à coffrage intégré, et à un mur à coffrage intégré comprenant un tel ensemble d'armatures, une méthode de réalisation d'un tel mur à coffrage intégré, et à un mur de construction comprenant un tel mur à coffrage intégré.The present invention relates to the field of the construction of a building, and relates to a set of frames comprising a wall connecting frame of a wall with integrated formwork, and to a wall with integrated formwork comprising such a set of reinforcements, a method of producing such a wall with integrated formwork, and to a construction wall comprising such a wall with integrated formwork.

Etat de la techniqueState of the art

Les treillis métalliques sont utilisés dans de nombreux domaines techniques.Metal meshes are used in many technical fields.

Par exemple, dans le domaine des écrans de protection, un domaine éloigné de celui de la présente invention, le document GB1524824 décrit un treillis ondulé, présentant des crêtes et des creux, et comprenant des fils longitudinaux, parallèles les uns aux autres, et reliés entre eux par des fils transversaux parallèles les uns aux autres, tous fixés sur un seul coté des fils longitudinaux.For example, in the field of protective screens, a field remote from that of the present invention, the document GB1524824 describes a corrugated mesh, having crests and hollows, and comprising longitudinal wires, parallel to each other, and interconnected by transverse wires parallel to each other, all fixed on a single side of the longitudinal wires.

Dans le domaine de la construction, en particulier de la construction de bâtiments, il est courant d'utiliser des murs en béton renforcés par au moins une armature métallique.In the field of construction, in particular the construction of buildings, it is common to use concrete walls reinforced by at least one metal reinforcement.

Par exemple, le document FR 466 945 décrit des pièces de charpente, formées d'une armature formant un grillage, ayant un profil ondulé, à prismes saillants ou augets rentrants, et supportant un écran en treillis, obturant les grandes mailles de l'armature, et permettant de retenir le béton sur les pièces de charpente, le treillis passant alternativement en dessous et au-dessus des éléments formant l'armature.For example, the document FR 466 945 describes structural parts, formed of a reinforcement forming a mesh, having an undulating profile, with salient prisms or re-entrant troughs, and supporting a latticework screen, closing the large meshes of the reinforcement, and making it possible to retain the concrete on the structural members, the trellis passing alternately below and above the elements forming the reinforcement.

Le document BE1012524 décrit une structure tridimensionnelle de renfort interne d'un panneau en béton, comprenant des fils métalliques, pliés en sinusoïde, de forme trapézoïdale, et reliés par des fils rectilignes, notamment soudés dans les bases des trapzoïdes.The document BE1012524 describes a three-dimensional structure for internal reinforcement of a concrete panel, comprising metallic wires, bent in a sinusoid, of trapezoidal shape, and connected by straight wires, in particular welded in the bases of the trapzoids.

Le document CA1145228 décrit une structure de renfort d'une paroi en béton, fait d'un treillis tridimensionnel interne, en forme de créneaux, soudé de part et d'autre à deux treillis plats, les fils de chaine des trois treillis, se superposant. Les fils de trame de chaque treillis plat sont positionnés soit vers l'extérieur ou l'intérieur de la structure de renfort, et positionnés au centre, et sur, chaque portion horizontale des créneaux, le treillis tridimensionnel interne pouvant comprendre également un seul fil de trame, disposé au centre, et sur, chaque portion horizontale des créneaux.The document CA1145228 describes a reinforcement structure for a concrete wall, made of an internal three-dimensional mesh, in the form of crenellations, welded on either side to two flat meshes, the warp threads of the three meshes being superimposed. The weft threads of each flat trellis are positioned either towards the outside or the inside of the reinforcement structure, and positioned in the center, and on, each horizontal portion of the slots, the internal three-dimensional trellis which may also comprise a single weft thread, placed in the center and on each horizontal portion of the slots.

Par ailleurs, il est également connu d'avoir recours à des éléments de construction préfabriqués en usine, qui sont ensuite acheminés sur le lieu de construction. De tels éléments peuvent être des murs à coffrage intégré, ou MCI, encore appelés des « prémurs », ou bien encore des dalles, appelées « prédalles ».Moreover, it is also known to have recourse to prefabricated building elements in the factory, which are then transported to the place of construction. Such elements can be walls with integrated formwork, or MCI, also called “double walls”, or even slabs, called “pre-slabs”.

Les murs à coffrage intégré font office de coffrage pour la réalisation du mur final, et font partie intégrante du mur final. Ils comprennent habituellement deux parois, encore appelée « peaux », généralement faites en béton, et renforcées par un treillis métallique soudé plat. Les parois se font face, de façon sensiblement parallèle l'une par rapport à l'autre, et sont maintenues à distance, l'une de l'autre, par au moins une armature de liaison, de préférence métallique, faite ou comprenant des éléments de renfort, des poutrelles ou des raidisseurs métalliques, l'espace entre les deux parois étant destiné à recevoir un matériau pouvant être coulé, comme par exemple du béton ou un matériau isolant, afin de former un mur définitif.The walls with integrated formwork act as formwork for the realization of the final wall, and are an integral part of the final wall. They usually include two walls, also called "skins", generally made of concrete, and reinforced with a flat welded metal mesh. The walls face each other, substantially parallel to each other, and are held at a distance from each other by at least one connection reinforcement, preferably metallic, made or comprising reinforcing elements, beams or metal stiffeners, the space between the two walls being intended to receive a material which can be cast, such as for example concrete or an insulating material, in order to form a final wall.

Pour la réalisation d'un mur comprenant une réservation, à savoir un mur dont la paroi n'est pas pleine, mais comprenant une cavité en prévision du passage d'un conduit ou la pose d'une porte ou d'une fenêtre, il est nécessaire que l'armature de liaison soit interrompue pour former une ouverture adaptée à ladite réservation.For the realization of a wall comprising a reservation, namely a wall whose wall is not solid, but comprising a cavity in anticipation of the passage of a conduit or the installation of a door or a window, it is necessary that the connecting frame is interrupted to form an opening adapted to said reservation.

Généralement, un mur à coffrage intégré est réalisé par la mise en œuvre d'une étape de confection d'une première paroi du mur, en coulant du béton sur une armature de renfort, généralement un premier treillis métallique plat, et une première portion de plusieurs éléments raidisseurs faisant office d'armatures de liaison, puis en durcissant le béton, habituellement en étuve. Ensuite, la seconde paroi est réalisée en coulant du béton sur un second treillis métallique plat. Après avoir disposé la première paroi en regard et au-dessus de la seconde paroi, une autre portion des éléments raidisseurs est noyée dans le béton frais de la seconde paroi, puis le béton est durci.Generally, a wall with integrated formwork is produced by the implementation of a step of making a first wall of the wall, by pouring concrete on a reinforcement frame, generally a first flat metal mesh, and a first portion of several stiffening elements acting as connection reinforcements, then by hardening the concrete, usually in an oven. Then, the second wall is made by pouring concrete on a second flat wire mesh. After placing the first wall opposite and above the second wall, another portion of the stiffening elements is embedded in the fresh concrete of the second wall, then the concrete is hardened.

L'emploi d'une multitude d'éléments raidisseurs, de poutrelles, en plus d'être chronophage, augmente le risque d'une mauvaise mise en place des éléments raidisseurs au niveau des parois, ou, tout du moins, augmente le risque d'une pose hors des tolérances acceptables.The use of a multitude of stiffening elements, of beams, in addition to being time-consuming, increases the risk of improper installation of the stiffening elements at the level of the walls, or, at the very least, increases the risk of installation outside of acceptable tolerances.

Par ailleurs, les éléments raidisseur assurent la résistance structurelle du mur final, en particulier lors de sa réalisation sur le site de construction. Toutefois, lors de coulées trop rapide du béton entre les deux parois du coffrage, les éléments raidisseurs subissent des contraintes importantes, qui entrainent l'arrachement de la partie de l'armature de liaison noyée dans les parois, et conduisent à l'arrachement de portions de béton des parois de coffrage, et donc à des ruptures de l'intégrité de ces dernières.In addition, the stiffening elements ensure the structural resistance of the final wall, in particular during its construction on the construction site. However, when too rapid pouring of the concrete between the two walls of the formwork, the stiffening elements undergo significant stresses, which cause the tearing of the part of the connecting reinforcement embedded in the walls, and lead to the tearing of portions of concrete from the formwork walls, and therefore to breaks in the integrity of the latter.

Elle est apte à assurer, et en place dans l'élément de construction, elle assure la liaison, la jonction physique, mécanique, entre les deux parois formant un mur à coffrage intégré, en s'étendant dans l'espace séparant les deux parois du mur.The connecting reinforcement 1 according to the invention comprises, or is, a structure in relief, three-dimensional, namely a structure which extends substantially in the three dimensions of space, along the axes X'-X, Y' -Y and Z'-Z of the XYZ frame ( figure 1 ). It is able to ensure, and in place in the construction element, it ensures the connection, the physical, mechanical junction, between the two walls forming a wall with integrated formwork, by extending into the space separating the two walls from the wall.

L'armature de liaison 1 selon l'invention présente l'avantage de conférer à l'élément de construction qui la comprend, une qualité de réalisation améliorée, que ne peut être procurée par l'emploi d'une multitude d'éléments raidisseurs indépendants.The connecting reinforcement 1 according to the invention has the advantage of giving the construction element which comprises it an improved quality of construction, which cannot be provided by the use of a multitude of independent stiffening elements. .

L'armature de liaison 1 selon l'invention a une forme générale, dans le plan X-Z, et des dimensions, qui sont adaptées à, en tout état de cause fonction de, la forme et des dimensions du mur à coffrage intégré qui l'intègre et celles du mur final. Néanmoins, dans la suite de la description, l'armature de liaison 1 est décrite en référence aux figures 1, 2 et 6, dans lesquelles elle a une forme générale, dans le plan X-Z, qui est polygonale, de préférence la forme d'un quadrilatère, avantageusement d'un parallélogramme, encore plus avantageusement d'un parallélogramme rectangle.The connecting reinforcement 1 according to the invention has a general shape, in the XZ plane, and dimensions, which are adapted to, in any event depending on, the shape and dimensions of the wall with integrated formwork which integrity and those of the final wall. Nevertheless, in the rest of the description, the connecting reinforcement 1 is described with reference to the figures 1, 2 and 6 , in which it has a general shape, in the XZ plane, which is polygonal, preferably the shape of a quadrilateral, advantageously of a parallelogram, even more advantageously of a rectangular parallelogram.

L'armature de liaison 1 a une forme générale, dans le plan X-Y, en forme de créneaux. Elle a une section longitudinale, selon l'axe X'-X, faite de, ou comprenant, une succession de portions sigmoïdes ascendantes et descendantes, de « U » et « U » inversé, la lettre « oméga » sous sa forme majuscule (Ω), ou sensiblement en forme de la lettre « oméga » sous sa forme majuscule.The connecting armature 1 has a general shape, in the X-Y plane, in the form of slots. It has a longitudinal section, along the X'-X axis, made of, or comprising, a succession of ascending and descending sigmoid portions, of "U" and inverted "U", the letter "omega" in its capital form ( Ω), or substantially in the shape of the letter "omega" in its capital form.

De préférence, l'armature de liaison 1 présente une symétrie par rapport au plan Y-Z, ou au plan X-Y, ou au plan X-Z, ou une combinaison quelconque de ces plans.Preferably, the connection reinforcement 1 has a symmetry with respect to the Y-Z plane, or to the X-Y plane, or to the X-Z plane, or any combination of these planes.

Quelque soit sa forme et ses dimensions, l'armature de liaison 1 comprend une multitude de fils de chaîne 2 et une multitude de fils de trame 3, 4 et 5, qui sont liés aux fils de chaine 2 par tous moyens adéquats, de préférence, par soudure.Whatever its shape and dimensions, the connecting reinforcement 1 comprises a multitude of warp threads 2 and a multitude of weft threads 3, 4 and 5, which are linked to the warp threads 2 by any suitable means, preferably , by welding.

L'armature de liaison 1 comprend un seul type de fils de chaîne 2, qui sont en relief ou forment des reliefs. L'armature de liaison 1 ne comprend pas des fils de chaines supplémentaires qui seraient entièrement rectilignes, ou entièrement plan.The connecting reinforcement 1 comprises a single type of warp threads 2, which are in relief or form reliefs. The connecting frame 1 does not include additional warp threads which would be entirely straight, or entirely flat.

Comme cela est représenté, par exemple, aux figures 1 à 6, tous les fils de chaîne 2 de l'armature de liaison s'étendent longitudinalement, selon l'axe X'-X, dans le plan X-Y, selon une succession de portions sigmoïdes ascendantes et descendantes, une succession de « U » et « U » inversé, de la lettre « oméga » sous sa forme majuscule (Ω), ou sensiblement en forme de la lettre « oméga » sous sa forme majuscule.As shown, for example, in figures 1 to 6 , all the warp threads 2 of the connecting reinforcement extend longitudinally, along the axis X′-X, in the XY plane, according to a succession of ascending and descending sigmoid portions, a succession of "U" and inverted "U", of the letter "omega" in its capital form (Ω), or substantially in the form of the letter "omega" in its uppercase form.

Chaque fils de chaîne 2 comprend des portions 6, dites « inférieures », de préférence planes, auxquelles succèdent d'autres portions 7, dites « supérieures», de préférence planes, qui s'étendent toutes avantageusement dans un plan sensiblement horizontal, parallèle ou sensiblement parallèle au plan X-Z, et de part et d'autre d'un plan médian P, qui est parallèle ou sensiblement parallèle au plan X-Z, de façon symétrique ou bien asymétrique, par rapport au plan médian P (Figure 3).Each warp yarn 2 comprises portions 6, called "lower", preferably planar, followed by other portions 7, called "upper", preferably planar, which all advantageously extend in a substantially horizontal plane, parallel or substantially parallel to the XZ plane, and on either side of a median plane P, which is parallel or substantially parallel to the XZ plane, symmetrically or asymmetrically, with respect to the median plane P ( Figure 3 ).

De préférence, les portions inférieures 6 et les portions supérieures 7 sont sensiblement planes, ou rectilignes, s'étendant sensiblement horizontalement, dans un plan sensiblement parallèle au plan X-Z.Preferably, the lower portions 6 and the upper portions 7 are substantially planar, or rectilinear, extending substantially horizontally, in a plane substantially parallel to the X-Z plane.

Chaque portion supérieure 7 est séparée de chaque portion inférieure 6 par deux segments latéraux 8 et 9, s'étendant sensiblement verticalement, perpendiculairement ou de façon oblique, par rapport aux portions 6 et 7, et forment avec ces dernières respectivement, des coudes supérieurs 10 et des coudes inférieurs 11.Each upper portion 7 is separated from each lower portion 6 by two lateral segments 8 and 9, extending substantially vertically, perpendicularly or obliquely, with respect to the portions 6 and 7, and form with the latter respectively, upper elbows 10 and lower elbows 11.

Au sein de l'armature 1, pour chaque fils de chaine 2, deux portions inférieures 6 consécutives sont séparées par un espace E1, et deux portions supérieures 7 sont séparées par un espace E2.Within the reinforcement 1, for each warp yarn 2, two consecutive lower portions 6 are separated by a space E1, and two upper portions 7 are separated by a space E2.

Même s'il est concevable que les différents fils de chaîne 2 soient disposés, au sein de l'armature de liaison 1, d'une façon quelconque, décalée les uns par rapport aux autres, ou une façon partiellement décalée, selon un motif répétitif ou non répétitif, ils sont, de préférence, disposés les uns par rapport aux autres, de manière à ce que les portions inférieures 6 et les portions supérieures 7 d'un fil de chaine 2, soient en rapport avec, c'est-à-dire disposé en face de, respectivement celles des fils de chaîne 2 adjacents, le long de l'axe Z-Z', les espaces E1 et E2 se trouvant alors alignés selon l'axe Z-Z'.Even if it is conceivable that the different warp threads 2 are arranged, within the connecting reinforcement 1, in any way, offset from each other, or partially offset, according to a repetitive pattern or non-repetitive, they are preferably arranged relative to each other, so that the lower portions 6 and the upper portions 7 of a warp yarn 2 are related to, that is to say that is to say disposed opposite, respectively, those of the adjacent warp threads 2, along the axis Z-Z', the spaces E1 and E2 then being aligned along the axis Z-Z'.

Les successions des portions inférieures 6 et deux portions supérieures 7 de chaque fils de chaine 2 adjacents forment alors, par rapport au plan formé par les portions inférieures 6, des canaux transversaux en saillies 12, formés par une succession d'espaces intérieurs E1, ou, par rapport au plan médian P, une série de canaux transversaux en saillies 12, et une série de canaux transversaux en creux 13, formés par une succession d'espaces intérieurs E2, des canaux transversaux 12 et 13 qui s'étendent, de préférence de façon symétrique deux à deux, de part et d'autre du plan médian P, le long de l'axe Z-Z', mais avantageusement également deux à deux, de façon symétrique de part et d'autre d'un plan sensiblement parallèle au plan Y-Z.The successions of the lower portions 6 and two upper portions 7 of each adjacent warp yarn 2 then form, relative to the plane formed by the lower portions 6, projecting transverse channels 12, formed by a succession of interior spaces E1, or , with respect to the median plane P, a series of projecting transverse channels 12, and a series of recessed transverse channels 13, formed by a succession of interior spaces E2, transverse channels 12 and 13 which extend, preferably symmetrically two by two, on either side 'other of the median plane P, along the axis Z-Z', but also advantageously two by two, symmetrically on either side of a plane substantially parallel to the plane YZ.

L'armature de liaison 1 en place dans le mur à coffrage intégré, les canaux 12, 13 facilitent la coulée du matériau, ou assemblage de matériaux, destiné à remplir l'espace entre les deux parois du mur à coffrage intégré, réduisant ainsi les forces et contraintes liées à cette coulée, qui s'exercent sur l'armature de liaison 1.The connecting reinforcement 1 in place in the wall with integrated formwork, the channels 12, 13 facilitate the casting of the material, or assembly of materials, intended to fill the space between the two walls of the wall with integrated formwork, thus reducing the forces and stresses related to this casting, which are exerted on the connecting reinforcement 1.

Les fils de chaîne 2 de l'armature de liaison 1 sont reliés entre eux par au moins une première série de deux fils de trame 3, sensiblement rectilignes, fixés au niveau des portions supérieures 7, et s'étendant de préférence dans l'espace E1 des canaux en saillie 12, et avantageusement également par une seconde série de fils deux de trame 4 sensiblement rectilignes, fixés au niveau des portions inférieures 6, et s'étendant de préférence dans l'espace E2 des canaux en creux 13.The warp threads 2 of the connecting reinforcement 1 are interconnected by at least a first series of two substantially straight weft threads 3, fixed at the level of the upper portions 7, and preferably extending in space E1 of the projecting channels 12, and advantageously also by a second series of two substantially straight weft threads 4, fixed at the level of the lower portions 6, and preferably extending into the space E2 of the hollow channels 13.

De préférence, les fils de trame 3, 4 sont pourvus respectivement de part et d'autre des fils de chaque fil de chaine 2. Avantageusement les fils de trame 3 de la première série sont pourvus en dessous de chaque fils de chaine 2, dans le canal transversal 12, dans l'espace E1, les fils de trame 4 de la seconde série sont pourvus au dessus de chaque fils de chaine 2, dans le canal transversal 13, dans l'espace E2 (Figures 3 à 5).Preferably, the weft threads 3, 4 are provided respectively on either side of the threads of each warp thread 2. Advantageously the weft threads 3 of the first series are provided below each warp thread 2, in the transverse channel 12, in the space E1, the weft yarns 4 of the second series are provided above each warp yarn 2, in the transverse channel 13, in the space E2 ( Figures 3 to 5 ).

De préférence, les fils de trame 3 sont pourvus à proximité des coudes supérieurs 10, avantageusement dans les coudes supérieurs 10. Les fils de trame 4 sont pourvus, à proximité, de préférence dans les coudes inférieurs 11.Preferably, the weft threads 3 are provided close to the upper bends 10, advantageously in the upper bends 10. The weft threads 4 are provided close to, preferably in the lower bends 11.

Cela présente l'avantage d'améliorer la résistance de l'armature de liaison 1 à l'arrachement, et donc de la paroi du mur à coffrage intégré, durant le processus de bétonnage, à savoir à la coulée de béton dans le mur à coffrage intégré. En effet, les contraintes liées à la coulée de béton qui s'exercent sur les segments latéraux 8 et 9 sont réparties sur au moins deux points d'appui de l'armature de liaison 1 fournis par les fils de trame 3, avantageusement également sur deux point s d'appui supplémentaires par les fils de trame 4. Cela permet de réduire les risques d'arrachement du béton de la surface interne des parois du mur à coffrage intégré.This has the advantage of improving the resistance of the connecting reinforcement 1 to tearing, and therefore of the wall of the wall with integrated formwork, during the concreting process, namely the pouring of concrete into the wall at integrated formwork. Indeed, the stresses related to the pouring of concrete which are exerted on the lateral segments 8 and 9 are distributed over at least two points of support of the connecting reinforcement 1 provided by the weft threads 3, advantageously also on two additional points of support by the weft threads 4. This makes it possible to reduce the risk of tearing of the concrete from the internal surface of the walls of the wall with integrated formwork.

De préférence, les fils de chaîne 2 sont également reliés entre eux par une troisième série de fils de trame 5, avantageusement d'une troisième série de deux fils de trame 5, fixés également au niveau des portions inférieures 6, mais avantageusement éloignés des coudes inférieurs 11, et donc des fils de trame 4. Cela permet d'améliorer la stabilité structurelle de l'armature de liaisons 1 et d'améliorer encore plus sa résistance à l'arrachement lors de la coulée de matériaux de maçonnerie ou d'isolation, par exemple de béton, dans l'espace séparant les deux parois du mur à coffrage intégré.Preferably, the warp threads 2 are also interconnected by a third series of weft threads 5, advantageously a third series of two weft threads 5, also fixed at the level of the lower portions 6, but advantageously distant from the elbows lower 11, and therefore of the weft threads 4. This makes it possible to improve the structural stability of the link reinforcement 1 and to further improve its resistance to tearing during the casting of masonry or insulation materials , for example of concrete, in the space separating the two walls of the wall with integrated formwork.

De préférence, ces fils de trame 5 sont pourvus entre les fils de trame 4 de deux portions inférieures 6 consécutives.Preferably, these weft threads 5 are provided between the weft threads 4 with two consecutive lower portions 6.

De préférence, les fils de trame 3, 4 et 5 ne sont pas en relief. Ils sont sensiblement rectilignes sur toute leur longueur au sein de l'armature de liaison 1.Preferably, the weft threads 3, 4 and 5 are not in relief. They are substantially straight over their entire length within the connecting frame 1.

Par exemple, et comme cela est représenté à la figure 3, deux fils de trame 3 sont fixés, de préférence soudés, au niveau des portions supérieures 7 de chaque fil de chaîne 2, de préférence sous les fils de chaine 2, à proximité des coudes supérieurs 10. Deux fils de trame 4 sont fixés, de préférence soudés, un fil 4 à la base de chaque segment latéral 8 et 9, de préférence au-dessus des fils de chaine 2, à proximité ou dans les coudes inférieurs 11. De préférence, au moins deux, de préférence une multitude de fils de trame 5 sont fixés, de préférence soudés, au-dessus des fils de chaine 2 entre les coudes inférieurs 11, de préférence espacés d'une distance constante.For example, and as shown in picture 3 , two weft threads 3 are fixed, preferably welded, at the level of the upper portions 7 of each warp thread 2, preferably under the warp threads 2, close to the upper bends 10. Two weft threads 4 are fixed, preferably welded, a wire 4 at the base of each side segment 8 and 9, preferably above the warp wires 2, near or in the lower bends 11. Preferably, at least two, preferably a multitude of weft threads 5 are fixed, preferably welded, above the warp threads 2 between the lower bends 11, preferably spaced apart by a constant distance.

La forme et les dimensions de la section longitudinale, selon l'axe X'-X, des portions sigmoïdes, en U ou en oméga majuscule, de même que la longueur et le diamètre des fils de chaîne 2 et des fils de trame 3, 4 et 5 sont fonction de la forme et des dimensions de l'armature de liaison 1, du mur à coffrage intégré, de la grandeur de l'espace entre les deux paroi du mur à coffrage intégré, et du mur final à construire.The shape and dimensions of the longitudinal section, along the X'-X axis, of the sigmoid, U-shaped or capital omega portions, as well as the length and diameter of the warp threads 2 and the weft threads 3, 4 and 5 depend on the shape and dimensions of the connecting frame 1, the wall with integrated formwork, the size of the space between the two walls of the wall with integrated formwork, and the final wall to be built.

The different lengths L1 also constitute the widths of the bottom of the different recessed channels 13 ( Figure 4 ).

Les segments latéraux 8 et 9 des fils de chaines 2 s'étendent depuis, ou vers, les portions inférieure 6 ou respectivement les portions supérieures 7, selon une distance H, qui représente l'épaisseur de l'armature de liaison 1, selon l'axe Y-Y'. Cette distance est fonction adaptée et fonction de l'épaisseur des parois du mur à coffrage intégré et fonction de la grandeur de l'espace séparant les deux parois du mur à coffrage intégré, ainsi que du ou des matériaux qui vont être coulés entre les parois du mur à coffrage intégré.The lateral segments 8 and 9 of the warp threads 2 extend from or towards the lower portions 6 or respectively the upper portions 7, according to a distance H, which represents the thickness of the connecting reinforcement 1, according to l 'Y-Y axis'. This distance is a suitable function and a function of the thickness of the walls of the wall with integrated formwork and a function of the size of the space separating the two walls of the wall with integrated formwork, as well as the material or materials which will be poured between the walls of the wall with integrated formwork.

Les segments latéraux 8 et 9 des fils de chaines 2 forment un angle α avec les portions inférieures 6 des fils de chaine 2 qui peut être différent, mais est de préférence identique, entre chaque portion inférieure 6 du ou des fils de chaine 2, tout du long du ou des fils de chaîne 2.The lateral segments 8 and 9 of the warp yarns 2 form an angle α with the lower portions 6 of the warp yarns 2 which may be different, but is preferably identical, between each lower portion 6 of the warp yarn(s) 2, while along the warp thread(s) 2.

Les différentes longueurs L3 constituent également les largeurs du fond des différents canaux en saillie 12.Preferably, the sigmoid portions, in the shape of a "U", or of a capital omega, comprise a length at the base L2, along the X-X' axis, identical or different for the same warp yarn 2, which is equal , or preferably greater than their length at the top L3, and which is equal to, or preferably less than the length L1. The different lengths L3 also constitute the bottom widths of the different projecting channels 12.

De préférence, les portions inférieures 6 et les portions supérieures 7 d'un fil de chaîne 2 se succèdent, le long du fil de chaine 2 et du plan médian P, à une fréquence constante.
