Cette invention a, également, trait à un mur isolant à coffrage intégré comportant une pluralité de ces poutrelles ainsi qu'à un procédé de fabrication d'un tel mur isolant.The present invention relates to an insulated wall beam with integrated formwork. This invention also relates to an insulating wall with integrated formwork comprising a plurality of these beams and a method of manufacturing such an insulating wall.

Cette invention concerne le domaine du bâtiment et, plus particulièrement, celui de la fabrication, en usine, des murs isolants à coffrage intégré.This invention relates to the field of building and, more particularly, that of the manufacture, at the factory, of insulating walls with integrated formwork.

Par le document FR-2.424.378 , on connaît un mur à coffrage intégré comportant une paroi réalisée en béton ainsi qu'une paroi isolante, réalisée en un matériau isolant, et s'étendant parallèlement à la paroi en béton, ceci à une distance déterminée de cette paroi en béton en sorte de définir un espacement destiné à recevoir un matériau de remplissage.By the document FR-2424378 there is known an integrated form wall comprising a wall made of concrete and an insulating wall, made of an insulating material, and extending parallel to the concrete wall, this at a determined distance from this concrete wall so defining a spacing for receiving a filling material.

Un tel mur à coffrage intégré comporte, également, une pluralité de poutrelles comportant, chacune, d'une part, une embase, constituée par un fil métallique, et destinée à recevoir la paroi isolante et, d'autre part, des pieds, s'étendant à partir de l'embase, et présentant des extrémités libres, s'étendant dans un plan, et destinées à être noyées dans le béton de la paroi en béton. En fait un tel pied comporte, d'une part, un premier fil métallique, constituant l'extrémité libre d'un tel pied, s'étendant parallèlement au fil métallique de l'embase et, d'autre part, un deuxième fil métallique, conformé en zigzag, interposé entre le fil métallique de l'embase et le premier fil métallique d'un tel pied, et raccordant ces deux fils métalliques.Such integrated form wall also comprises a plurality of beams each comprising, on the one hand, a base constituted by a metal wire, and intended to receive the insulating wall and, on the other hand, feet, s extending from the base, and having free ends, extending in a plane, and intended to be embedded in the concrete of the concrete wall. In fact, such a foot comprises, on the one hand, a first wire constituting the free end of such a foot, extending parallel to the wire of the base and, on the other hand, a second wire , shaped in zigzag, interposed between the wire of the base and the first wire of such a foot, and connecting these two metal son.

Un inconvénient de ces poutrelles consiste en ce que, lors de leur manipulation, de leur stockage, et/ou de leur transport, ces poutrelles ont tendance à subir une déformation. Aussi, lorsque la paroi isolante est fixée sur une telle poutrelle déformée, la déformation de cette poutrelle entraîne, également, une déformation de la paroi isolante dont la surface, orientée en direction de l'extérieur du mur isolant, présente, alors, un défaut de planéité.A disadvantage of these beams is that, during their handling, storage, and / or transport, these beams tend to undergo deformation. Also, when the insulating wall is fixed on such a deformed beam, the deformation of this beam also results in a deformation of the insulating wall whose surface, oriented in the direction of the outside of the insulating wall, then presents a lack of flatness.

Pour la réalisation du mur à coffrage intégré comportant de telles poutrelles, on a recours à des liteaux en bois qui sont disposés à intervalles réguliers sur une telle poutrelle et attachés à une telle poutrelle. Entre les rangées de liteaux on enfonce des plaques de matériau isolant pour constituer la paroi isolante. On cloue, ensuite, des voliges sur les liteaux et, finalement, on fixe, sur ces voliges, soit des plaques de plâtre cartonné ou un grillage sur lequel on coule du plâtre. Ce procédé de fabrication comporte, alors, de nombreuses étapes et nécessite l'emploi de nombreux matériaux différents ce qui, d'une part, rend ce procédé long et fastidieux et, d'autre part, renchérit le coût du mur isolant obtenu par la mise en oeuvre de ce procédé. De plus, la surface externe de la paroi isolante comporte du plâtre (notamment cartonné) ce qui impose d'orienter cette paroi isolante vers l'intérieur du bâtiment.For the production of the integrated form wall comprising such beams, wooden battens are used which are arranged at regular intervals on such a beam and attached to such a beam. Between the rows of battens are pressed plates of insulating material to form the insulating wall. Nails are then nailed to the battens and, finally, fixed gypsum boards or a grid on which plaster is poured are fixed on these flights. This manufacturing process then involves many steps and requires the use of many different materials which, on the one hand, makes this process long and tedious and, on the other hand, increases the cost of the insulating wall obtained by the implementation of this method. In addition, the outer surface of the insulating wall comprises plaster (including cardboard) which requires to direct this insulating wall towards the interior of the building.

On connaît, également, des murs isolants à coffrage intégré comportant une paroi en béton, une paroi isolante espacée de cette paroi en béton, et une pluralité de poutrelles telles que décrites ci-dessus.There are also known insulating walls with integrated formwork comprising a concrete wall, an insulating wall spaced from this concrete wall, and a plurality of beams as described above.

En fait, dans un tel mur isolant, le fil métallique de l'embase d'une poutrelle est noyé dans la paroi en béton tandis qu'au moins le premier fil métallique de chaque pied de cette poutrelle est noyé dans un insert de béton coulé dans une rainure ménagée dans la paroi isolante d'un tel mur isolant.In fact, in such an insulating wall, the wire of the base of a beam is embedded in the concrete wall while at least the first wire of each foot of this beam is embedded in a poured concrete insert in a groove in the insulating wall of such an insulating wall.

Le procédé de fabrication d'un tel mur isolant nécessite, alors, une étape au cours de laquelle on usine des rainures dans la paroi isolante. Outre le fait qu'un tel usinage constitue une étape supplémentaire dans le procédé de fabrication d'un tel mur isolant, ce procédé nécessite aussi de couler du béton dans les rainures de la plaque isolante mais, également, d'assurer le durcissement de ce béton avant de procéder au retournement de cette plaque isolante pour incorporer les poutrelles dans un béton qui constituera la paroi en béton. Aussi, ce procédé nécessite d'assurer le durcissement du béton que comporte, d'une part, la paroi isolante et, d'autre part, la paroi en béton, ceci de manière successive ce qui allonge la durée de fabrication du mur isolant, notamment en doublant la durée de durcissement du béton par rapport à un mur isolant comportant uniquement une paroi en béton. Finalement, ce procédé nécessite l'utilisation de deux tables pour la fabrication du mur isolant et/ou d'un dispositif spécifique pour le retournement de la plaque isolante.The method of manufacturing such an insulating wall then requires a step during which grooves are machined in the insulating wall. In addition to the fact that such machining is an additional step in the manufacturing process of such an insulating wall, this method also requires pouring concrete into the grooves of the insulating plate but also to ensure the hardening of this material. concrete before reversing this insulating plate to incorporate the beams into a concrete that will constitute the concrete wall. Also, this process requires to ensure the hardening of the concrete that includes, a the insulating wall and, on the other hand, the concrete wall, this in a successive manner which lengthens the manufacturing time of the insulating wall, in particular by doubling the hardening time of the concrete with respect to an insulating wall comprising only one concrete wall. Finally, this process requires the use of two tables for the manufacture of the insulating wall and / or a specific device for the reversal of the insulating plate.

La présente invention se veut de remédier aux inconvénients des poutrelles de l'état de la technique.The present invention is intended to overcome the disadvantages of the beams of the prior art.

A cet effet, l'invention concerne une poutrelle de mur isolant à coffrage intégré, cette poutrelle comportant, d'une part, une embase destinée à recevoir une paroi isolante que comporte le mur isolant et qui est réalisée en un matériau isolant et, d'autre part, des pieds, s'étendant à partir de l'embase, et présentant des extrémités libres, s'étendant dans un plan, et destinées à être noyées dans une autre paroi du mur isolant réalisée en béton. Cette poutrelle est caractérisée par le fait que l'embase comporte une plaque rigide présentant une surface plane, destinée à recevoir la paroi isolante, et s'étendant selon un plan parallèle au plan dans lequel s'étendent les extrémités libres des pieds et que la poutrelle comporte des moyens pour maintenir ces plans à une distance déterminée l'un de l'autre.For this purpose, the invention relates to an insulated wall beam with integrated formwork, this beam comprising, on the one hand, a base intended to receive an insulating wall that comprises the insulating wall and which is made of an insulating material and, d on the other hand, feet extending from the base and having free ends extending in a plane and intended to be embedded in another wall of the insulating wall made of concrete. This beam is characterized in that the base comprises a rigid plate having a flat surface, intended to receive the insulating wall, and extending in a plane parallel to the plane in which the free ends of the feet extend and that the beam comprises means for maintaining these planes at a determined distance from one another.

L'invention concerne, également, un mur isolant à coffrage intégré comportant, d'une part, une paroi réalisée en béton, d'autre part, une paroi isolante, réalisée en un matériau isolant, s'étendant parallèlement à la paroi en béton et à une distance déterminée de cette paroi en béton en sorte de définir un espacement destiné à recevoir un matériau de remplissage, et, d'autre part encore, une pluralité de poutrelles, interposées entre les parois, et raccordant ces parois entre elles. Ce mur isolant est caractérisé par le fait que les poutrelles présentent les caractéristiques mentionnées ci-dessus.The invention also relates to an insulating wall with integrated formwork comprising, on the one hand, a wall made of concrete, on the other hand, an insulating wall, made of an insulating material, extending parallel to the concrete wall. and at a determined distance from this concrete wall so as to define a spacing for receiving a filler material, and, secondly, a plurality of beams, interposed between the walls, and connecting these walls together. This insulating wall is characterized in that the beams have the characteristics mentioned above.

Finalement, l'invention concerne un procédé de fabrication d'un tel mur isolant à coffrage intégré. Ce procédé est caractérisé par le fait que :

  • on applique un adhésif sur la surface plane de la plaque rigide de l'embase d'au moins une poutrelle présentant les caractéristiques décrites ci-dessus;
  • on positionne la surface plane de la plaque rigide de l'embase d'au moins une telle poutrelle par-dessus une paroi isolante ou on positionne une telle paroi isolante par-dessus une telle surface plane;
  • on fixe la surface plane de la plaque rigide de l'embase d'au moins une telle poutrelle sur la paroi isolante ou on fixe une telle paroi isolante sur une telle surface plane, au moins par l'intermédiaire de l'adhésif ;
  • on positionne les pieds d'au moins une telle poutrelle à l'intérieur d'un moule dans lequel on coule un béton pour la réalisation d'une paroi en béton.
Finally, the invention relates to a method of manufacturing such an insulating wall with integrated formwork. This process is characterized by the fact that:
  • an adhesive is applied to the flat surface of the rigid plate of the base of at least one beam having the characteristics described above;
  • positioning the flat surface of the rigid plate of the base of at least one such beam over an insulating wall or is positioned such an insulating wall over such a flat surface;
  • the flat surface of the rigid plate of the base of at least one such beam is fixed on the insulating wall or such an insulating wall is fixed on such a flat surface, at least by means of the adhesive;
  • positioning the feet of at least one such beam inside a mold in which a concrete is poured for the realization of a concrete wall.

Ainsi, la poutrelle comporte une embase comportant une plaque rigide présentant une surface plane destinée à recevoir la paroi isolante. Cette plaque rigide constitue, avantageusement, un support indéformable pour la réception de la paroi isolante qui est fixée sur cette plaque rigide, plus particulièrement par collage. En fixant cette paroi isolante sur la surface plane de cette plaque rigide indéformable, cette paroi isolante devient, elle-même, indéformable et présente, elle-même, une surface plane, plus particulièrement au niveau de sa face externe.Thus, the beam comprises a base comprising a rigid plate having a flat surface for receiving the insulating wall. This rigid plate is, advantageously, an indeformable support for the reception of the insulating wall which is fixed on this rigid plate, more particularly by gluing. By fixing this insulating wall on the flat surface of this rigid non-deformable plate, this insulating wall itself becomes indeformable and itself has a flat surface, more particularly at its external face.

Une autre caractéristique consiste en ce que la surface plane de la plaque rigide s'étend selon un plan parallèle au plan dans lequel s'étendent les extrémités libres des pieds. Ceci permet, avantageusement, lors de la fabrication du mur isolant et en positionnant les pieds dans le fond d'un moule (ou à une distance déterminée de ce fond), de positionner la surface plane de la plaque rigide de manière parallèle au fond du moule. En coulant le béton dans le moule pour réaliser la paroi en béton et en fixant la paroi isolante sur cette plaque rigide, ceci permet, avantageusement, d'assurer le parallélisme entre la face externe de la paroi en béton et la face externe de la paroi isolante.Another feature is that the flat surface of the rigid plate extends in a plane parallel to the plane in which the free ends of the feet extend. This allows, advantageously, during the manufacture of the insulating wall and positioning the feet in the bottom of a mold (or at a determined distance from this bottom), to position the flat surface of the rigid plate parallel to the bottom of the mold. Pouring the concrete into the mold to make the concrete wall and fixing the insulating wall on this rigid plate, this allows, advantageously, to ensure the parallelism between the outer face of the concrete wall and the outer face of the insulating wall.

Une caractéristique additionnelle consiste en ce que la poutrelle comporte des moyens pour maintenir les plans (selon lequel s'étend la surface plane de la plaque rigide de la poutrelle et dans lequel s'étendent les extrémités libres des pieds de la poutrelle) à une distance déterminée l'un de l'autre. La présence de ces moyens pour maintenir permet, avantageusement, de conserver la distance et le parallélisme entre les faces externes des parois en béton et isolante du mur isolant.An additional feature is that the beam comprises means for maintaining the planes (in which extends the flat surface of the rigid plate of the beam and in which the free ends of the legs of the beam extend) at a distance determined from each other. The presence of these means to maintain advantageously allows to maintain the distance and parallelism between the outer faces of the concrete walls and insulating wall insulation.

En choisissant la longueur appropriée des pieds de la poutrelle et/ou en positionnant de manière appropriée ces pieds par rapport à l'embase de la poutrelle et/ou en positionnant ces pieds à une distance déterminée du fond du moule (donc en ajustant la position de cette poutrelle en hauteur par rapport au fond du moule), et éventuellement en découpant la paroi isolante pour définir la face externe de cette paroi isolante, on confère au mur isolant une épaisseur calibrée.By choosing the appropriate length of the legs of the beam and / or by appropriately positioning these feet with respect to the base of the beam and / or positioning these feet at a determined distance from the bottom of the mold (thus adjusting the position of this beam height with respect to the bottom of the mold), and possibly by cutting the insulating wall to define the outer face of this insulating wall, the insulating wall is given a calibrated thickness.

De plus, en fabriquant un mur isolant incorporant du béton uniquement dans sa paroi en béton, on raccourcit substantiellement la durée de fabrication du mur isolant, ceci par rapport à un procédé de fabrication d'un mur isolant de l'état de la technique dont la paroi isolante comporte des inserts en béton.Moreover, by manufacturing an insulating wall incorporating concrete only into its concrete wall, the duration of manufacture of the insulating wall is substantially shortened, this compared to a method of manufacturing a insulating wall of the state of the art of which the insulating wall has concrete inserts.

De manière additionnelle et en fabriquant un mur isolant incorporant du béton uniquement dans sa paroi en béton, il est possible d'utiliser des outils existants (plus particulièrement conçus pour fabriquer des pré-dalles ou autres éléments préfabriqués) et, ainsi, de s'affranchir d'un équipement de fabrication coûteux (plus particulièrement comme celui pour retourner des murs à coffrage intégré).Additionally and by making an insulating wall incorporating concrete only into its concrete wall, it is possible to use existing tools (more particularly designed to manufacture pre-slabs or other prefabricated elements) and thus to free from costly manufacturing equipment (particularly the one used to return walls with integrated formwork).

Finalement, le collage de la paroi isolante sur une poutrelle permet, avantageusement, de ménager la face externe de cette paroi isolante, d'effectuer sur cette paroi isolante (plus particulièrement sur la face externe de cette paroi isolante) toutes les finitions nécessaires de façon simple, et/ou d'équiper cette paroi isolante avec une sous-couche, un entoilage, des tasseaux ou autres dispositifs destinés à recevoir un habillage extérieur.Finally, the bonding of the insulating wall on a beam makes it possible, advantageously, to protect the outer face of this insulating wall, to perform on this insulating wall (more particularly on the outer face of this insulating wall) all the necessary finishes in a simple manner, and / or to equip this insulating wall with an underlayer, a stabilizer, cleats or other devices intended to receive an outer covering.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre se rapportant à des modes de réalisation qui ne sont donnés qu'à titre d'exemples indicatifs et non limitatifs.Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

La présente invention concerne le domaine du bâtiment et, plus particulièrement, celui de la fabrication, en usine, des murs isolants à coffrage intégré.The present invention relates to the field of the building and, more particularly, that of the manufacture, at the factory, of insulating walls with integrated formwork.

Un tel mur isolant à coffrage intégré 1 comporte une paroi 2 réalisée en béton et destinée, usuellement, à être orientée en direction de l'intérieur du bâtiment comportant ce mur 1.Such an insulating wall integrated formwork 1 comprises a wall 2 made of concrete and usually intended to be oriented towards the interior of the building comprising the wall 1.

Ce mur isolant 1 comporte, également, une paroi 3 qui est au moins en partie réalisée en un matériau isolant (plus particulièrement en polystyrène, en polyuréthane, en fibres de bois ou analogue) et qui sera dénommée paroi isolante 3, ceci dans la suite de la description et pour des raisons de simplification. Cette paroi isolante 3 est destinée, usuellement, à être orientée en direction de l'extérieur du bâtiment comportant ce mur 1. Cette paroi isolante 3 s'étend parallèlement à la paroi en béton 2, ceci à une distance déterminée de cette paroi en béton 2 en sorte de définir un espacement 4 destiné à recevoir un matériau de remplissage, notamment un béton isolant ou analogue.This insulating wall 1 also comprises a wall 3 which is at least partly made of an insulating material (more particularly polystyrene, polyurethane, wood fiber or the like) and which will be called insulating wall 3, this in the following of the description and for reasons of simplification. This insulating wall 3 is usually intended to be oriented towards the outside of the building comprising the wall 1. This insulating wall 3 extends parallel to the concrete wall 2, this at a determined distance from this concrete wall. 2 so as to define a spacing 4 for receiving a filling material, in particular an insulating concrete or the like.

Un tel mur à coffrage intégré 1 comporte, également, une pluralité de poutrelles 5, s'étendant parallèlement les unes par rapport aux autres, interposées entre la paroi en béton 2 et la paroi isolante 3 de ce mur isolant 1, et raccordant entre elles ces parois (2 ; 3).Such integrated formwork wall 1 also comprises a plurality of beams 5, extending parallel to one another, interposed between the concrete wall 2 and the insulating wall 3 of this insulating wall 1, and connecting together. these walls (2; 3).

En fait, une telle poutrelle 5 comporte, d'une part, une embase 6 destinée à recevoir la paroi isolante 3 et, d'autre part, des pieds 7, s'étendant à partir de l'embase 6, et présentant, chacun, une extrémité libre 70. Les extrémités libres 70 de ces pieds 7 s'étendent dans un plan et sont destinées à être noyées dans le béton de la paroi en béton 2.In fact, such a beam 5 comprises, on the one hand, a base 6 intended to receive the insulating wall 3 and, on the other hand, feet 7, extending from the base 6, and having each , a free end 70. The free ends 70 of these feet 7 extend in a plane and are intended to be embedded in the concrete of the concrete wall 2.

Selon l'invention, l'embase 6 d'une telle poutrelle 5 comporte une plaque rigide 60 présentant une surface plane 61, destinée à recevoir la paroi isolante 3 du mur isolant 1, et s'étendant selon un plan parallèle au plan dans lequel s'étendent les extrémités libres 70 des pieds 7 de cette poutrelle 5. De manière additionnelle, une telle poutrelle 5 comporte des moyens pour maintenir ces plans à une distance déterminée l'un de l'autre.According to the invention, the base 6 of such a beam 5 comprises a rigid plate 60 having a flat surface 61, intended to receive the insulating wall 3 of the insulating wall 1, and extending in a plane parallel to the plane in which extend the free ends 70 of the feet 7 of this beam 5. Additionally, such a beam 5 comprises means for maintaining these planes at a determined distance from one another.

Selon un premier type de réalisation illustré figure 1 et 2, la plaque rigide 60 de l'embase 6 est réalisée en béton, notamment armé, tandis que les pieds 7 présentent, chacun, une extrémité 71, opposée à son extrémité libre 70, et qui, selon ce premier type de réalisation, est noyée dans le béton de la plaque rigide 60 de l'embase 6.According to a first type of embodiment illustrated figure 1 and 2 , the rigid plate 60 of the base 6 is made of concrete, including reinforced, while the feet 7 each have an end 71, opposite its free end 70, and which, according to this first embodiment, is embedded in the concrete of the rigid plate 60 of the base 6.

Une caractéristique additionnelle consiste en ce que les pieds 7 comportent, à proximité de leur extrémité 71 noyée dans le béton de la plaque rigide 60 de l'embase 6, des moyens 72 pour ancrer un tel pied 7 dans le béton de la plaque rigide 60 de l'embase 6. Ces moyens 72 pour ancrer peuvent adopter la forme d'au moins une aspérité, d'au moins une excroissance, d'au moins un aileron, notamment latéral.An additional feature is that the feet 7 have, near their end 71 embedded in the concrete of the rigid plate 60 of the base 6, means 72 for anchoring such a foot 7 in the concrete of the rigid plate 60 of the base 6. These means 72 for anchoring may adopt the shape of at least one asperity, at least one protrusion, at least one fin, in particular lateral.

Encore une autre caractéristique consiste en ce que l'extrémité 71 des pieds 7, noyée dans le béton de la plaque rigide 60 de l'embase 6, comporte des moyens (non représentés) pour positionner un tel pied 7 dans le béton de la plaque rigide 60 et/ou dans un moule (plus particulièrement dans le fond du moule) destiné à recevoir le béton pour la réalisation de cette plaque rigide 60. De tels moyens pour positionner peuvent adopter la forme d'une semelle ou analogue.Yet another feature is that the end 71 of the feet 7, embedded in the concrete of the rigid plate 60 of the base 6, comprises means (not shown) for positioning such a foot 7 in the concrete of the plate rigid 60 and / or in a mold (more particularly in the bottom of the mold) for receiving the concrete for the realization of this rigid plate 60. Such means for positioning may take the form of a sole or the like.

Tel que visible sur la figure 1, la poutrelle 5 conforme à l'invention peut encore avantageusement comporter un raidisseur 12. Un tel raidisseur 12 s'étend longitudinalement par rapport à l'embase 6 de la poutrelle 5 et comporte, d'une part, une base 120, s'étendant sensiblement parallèlement à cette embase 6, positionnée en retrait par rapport à l'extrémité libre 70 des pieds 7 de cette poutrelle 5, constituée par un fil métallique, et destinée à être noyée dans le béton de la paroi en béton 2 (à l'instar des extrémités libres 70 des pieds 7 de la poutrelle 5). D'autre part, un tel raidisseur 12 comporte des jambes 121, s'étendant à partir de la base 120 en divergeant, et présentant, chacune, une extrémité (notamment libre et/ou opposée à une extrémité associée à ladite base 120) noyée dans le béton de la plaque rigide 60 de l'embase 6 de la poutrelle 5. En fait une telle jambe 121 comporte, d'une part, un premier fil métallique, constituant l'extrémité (notamment libre) d'une telle jambe 121, s'étendant parallèlement au fil métallique de la base 120 et, d'autre part, un deuxième fil métallique, conformé en zigzag, interposé entre le fil métallique de la base 120 et le premier fil métallique d'une telle jambe 121, et raccordant ces deux fils métalliques. Ce deuxième fil métallique est soudé, d'une part, au fil métallique de la base 120 et, d'autre part, au premier fil métallique de la jambe 121, constituant l'extrémité (notamment libre) de cette la jambe 121.As visible on the figure 1 , the beam 5 according to the invention may also advantageously comprise a stiffener 12. Such a stiffener 12 extends longitudinally with respect to the base 6 of the beam 5 and comprises, on the one hand, a base 120, s' extending substantially parallel to this base 6, positioned recessed with respect to the free end 70 of the feet 7 of this beam 5, constituted by a wire, and intended to be embedded in the concrete of the concrete wall 2 (at 1 like the free ends 70 of the feet 7 of the beam 5). On the other hand, such a stiffener 12 has legs 121, extending from the base 120 diverging, and each having an end (including free and / or opposed to an end associated with said base 120) embedded in the concrete of the rigid plate 60 of the base 6 of the beam 5. In fact such a leg 121 comprises, on the one hand, a first wire constituting the end (especially free) of such a leg 121 , extending parallel to the wire of the base 120 and, secondly, a second metal wire, shaped zigzag, interposed between the wire of the base 120 and the first wire of such a leg 121, and connecting these two wires. This second wire is welded, on the one hand, to the wire of the base 120 and, on the other hand, to the first metal wire of the leg 121, constituting the end (especially free) of the leg 121.

Selon un deuxième type de réalisation, notamment illustré figures 3 et 4, l'embase 6 comporte une pièce 62, présentant une section en forme de « U », et comportant une paroi plane 63 ainsi que deux ailes 64, s'étendant à partir de cette paroi plane 63, et desquelles sont rendus solidaires les pieds 7 de la poutrelle 5, plus particulièrement l'extrémité 71 d'un tel pied 7 opposée à son extrémité libre 70.According to a second type of embodiment, illustrated in particular Figures 3 and 4 , the base 6 comprises a part 62, having a U-shaped section, and having a flat wall 63 and two wings 64, extending from this flat wall 63, and which are secured to the feet 7 of the beam 5, more particularly the end 71 of such a foot 7 opposite its free end 70.

En fait, les ailes 64 de la pièce 62 en « U », se situent dans le prolongement de la paroi plane 63, et s'étendent, chacune 64, à partir d'une extrémité longitudinale de cette paroi plane 63.In fact, the wings 64 of the "U" -shaped piece 62 lie in the extension of the plane wall 63, and each extend 64 from a longitudinal end of this plane wall 63.

Tel que visible sur les figures en annexe, les ailes 64 de la pièce 62 en « U » s'étendent de manière sensiblement perpendiculaire par rapport à la paroi plane 63.As can be seen in the appended figures, the wings 64 of the U-shaped piece 62 extend substantially perpendicular to the plane wall 63.

On observera que cette pièce 62 en « U » peut être réalisée en un matériau métallique tandis que les pieds 7, également réalisés en un matériau métallique, sont rendues solidaires de la pièce 62 en « U » (plus particulièrement des ailes 64 de cette pièce 62 en « U ») par soudure.It will be observed that this piece 62 in "U" may be made of a metallic material while the feet 7, also made of a metallic material, are made integral with the piece 62 in "U" (more particularly wings 64 of this piece 62 in "U") by welding.

An alternative method is that:
  • positioning at least one beam 5 having the characteristics described above, this inside a mold;
