Abstract

The wall has inner and outer skins (2, 3) respectively oriented inwards and outwards of a building. The skins are positioned opposite to each other so as to be parallel and at a certain distance from each other to define a gap packed by concrete that flows between the skins. The skins (2, 3) are constituted by concrete and facing plates (6, 7), respectively. The plate (7) has a plate made of an insulating material. An independent claim is also included for a method of fabricating a wall with an integrated formwork.

Description

La présente invention a trait à un procédé de fabrication de mur à coffrage intégré pour la réalisation d'un mur d'un bâtiment, notamment un mur extérieur. Cette invention a, encore, trait à un mur à coffrage intégré, notamment obtenu par la mise en oeuvre d'un tel procédé.The present invention relates to a method of manufacturing wall formwork integrated for the realization of a wall of a building, including an outer wall. This invention, again, relates to a formwork wall integrated, in particular obtained by the implementation of such a method.

L'invention concerne le domaine de l'industrie du bâtiment et, plus particulièrement, celui de la fabrication des murs à coffrage intégré utilisés dans le cadre de la construction d'un bâtiment pour la réalisation des murs d'un tel bâtiment. De tels murs à coffrage intégré sont, usuellement, connus sous la dénomination de pré-murs.The invention relates to the field of the building industry and, more particularly, that of the manufacture of integrated formwork walls used in the context of the construction of a building for the realization of the walls of such a building. Such formwork walls are usually known as pre-walls.

En fait, ces murs adoptent la forme d'une double peau et comportent, d'une part, une peau interne destinée à être orientée vers l'intérieur du bâtiment et, d'autre part, une peau externe destinée à être orientée en direction de l'extérieur du bâtiment.In fact, these walls take the form of a double skin and comprise, on the one hand, an inner skin intended to be oriented towards the interior of the building and, on the other hand, an outer skin intended to be oriented in the direction from outside the building.

Ces deux peaux sont constituées, chacune, par une plaque de béton et sont reliées entre elles par le biais de moyens de raccordement, usuellement constitués par des raidisseurs métalliques ou analogue, permettant de rendre ces deux peaux solidaires l'une de l'autre et d'en assurer l'immobilisation l'une par rapport à l'autre.These two skins are each constituted by a concrete slab and are interconnected by means of connecting means, usually constituted by metal stiffeners or the like, making it possible to make these two skins integral with one another and to ensure the immobilization one compared to the other.

On observera que ces deux peaux sont positionnées, au sein du mur à coffrage intégré, en regard l'une de l'autre, de manière sensiblement parallèle et à une certaine distance l'une de l'autre en sorte de définir entre elles un espacement destiné à être comblé par un béton coulé entre ces peaux lors de l'implantation de ce mur à coffrage intégré sur site.It will be observed that these two skins are positioned, within the integrated form wall, facing one another, substantially parallel and at a distance from one another so as to define between them a spacing intended to be filled by a concrete poured between these skins during the implantation of this formwork wall integrated on site.

Un tel mur présente un certain nombre d'inconvénients liés, d'une part, au processus de fabrication d'un tel mur et, d'autre part, aux éléments qui constituent ce dernier.Such a wall has a number of drawbacks related, on the one hand, to the process of manufacturing such a wall and, on the other hand, to the elements that constitute the latter.

Ainsi, lors de la fabrication d'un tel mur, l'on dispose des moyens de raccordement dans un moule et l'on coule, dans ce moule, du béton en vue de réaliser une première plaque de béton destinée à constituer l'une des peaux. Après séchage de cette première plaque de béton, l'on retourne celle-ci et on dispose les moyens de raccordement qui l'équipent dans un moule contenant du béton pour la réalisation d'une seconde plaque de béton destinée à constituer la seconde peau du mur. Après séchage de cette seconde peau, on démoule le mur pour en assurer le stockage et un séchage plus poussé.Thus, during the manufacture of such a wall, the connection means are available in a mold and concrete is poured into this mold in order to produce a first concrete plate intended to constitute one of the skins. After drying of the first concrete plate, the latter is turned over and the connecting means which equip it are placed in a mold containing concrete for the production of a second concrete plate intended to constitute the second skin of the concrete. Wall. After drying of this second skin, the wall is unmolded for storage and further drying.

Une telle fabrication impose, par conséquent, une durée de séchage particulièrement longue, notamment afin d'assurer le séchage, de manière successive et à coeur, de chacune des deux peaux. A ce propos, on observera qu'un tel séchage engendre, de plus, une consommation d'énergie importante pour le chauffage des moules dans lesquels est coulé le béton.Such a manufacture imposes, therefore, a particularly long drying time, in particular to ensure the drying, successively and at heart, of each of the two skins. In this connection, it will be observed that such drying generates, in addition, a significant energy consumption for heating the molds in which the concrete is poured.

En outre, il convient de faire appel à un outil spécialement conçu pour assurer le retournement de la première peau (usuellement contenue dans son moule au moins jusqu'à la fin de l'opération de retournement) en vue de la réalisation de la seconde peau. Un tel outil doit pouvoir soulever et retourner une plaque de béton de grande dimension et d'un poids conséquent (plusieurs tonnes), ceci sans risquer de dégrader cette plaque de béton.In addition, it is necessary to use a tool specifically designed to ensure the reversal of the first skin (usually contained in its mold at least until the end of the reversal operation) for the realization of the second skin . Such a tool must be able to lift and turn a large concrete plate and a large weight (several tons), without the risk of degrading the concrete plate.

Il convient, ensuite, d'assurer la manutention du mur de coffrage intégré en vue de son stockage et de son acheminement sur site. Pour ce faire, il est indispensable de faire appel à un engin de levage approprié et dimensionné en sorte de pouvoir charger/décharger et déplacer une charge importante, plus particulièrement sur un chantier où l'espace pour manoeuvrer un tel engin de levage et sa charge peut être particulièrement restreint.It is then necessary to ensure the handling of the integrated formwork wall for storage and on-site routing. To do this, it is essential to use a suitable lifting gear and sized to load / unload and move a large load, plus especially on a construction site where the space to maneuver such a lifting gear and its load can be particularly restricted.

De plus, après implantation sur site d'un tel mur, il convient d'équiper ce dernier à l'aide d'un isolant qui adopte, usuellement, la forme d'une plaque, notamment de polystyrène, qu'il convient de coller sur la paroi externe de la peau externe, ceci au cours d'une opération longue, fastidieuse et parfois risquée, notamment pour un collage en hauteur.In addition, after implantation on site of such a wall, it is necessary to equip the latter with the aid of an insulator which adopts, usually, the shape of a plate, especially polystyrene, which should be glued. on the external wall of the outer skin, this during a long operation, tedious and sometimes risky, especially for a collage in height.

A ce propos, on observera, encore, qu'une telle plaque d'isolant présente, usuellement, une surface externe irrégulière de sorte qu'il convient d'en assurer le ponçage et/ou le lissage au cours d'une opération qui produit des déchets (notamment des billes de polystyrène) qu'il est particulièrement difficile de recueillir et qui génèrent une pollution considérable et durable.In this regard, it will be observed, again, that such an insulating plate usually has an irregular external surface so that it should be sanding and / or smoothing during an operation which produces waste (especially polystyrene beads) which are particularly difficult to collect and which generate considerable and lasting pollution.

La présente invention se veut à même de remédier aux inconvénients des murs à coffrage intégré de l'état de la technique.The present invention is intended to overcome the disadvantages of integrated formwork walls of the state of the art.

A cet effet l'invention concerne un mur à coffrage intégré pour la réalisation d'un mur d'un bâtiment, plus particulièrement un mur extérieur, ce mur comportant, d'une part, une peau interne destinée à être orientée vers l'intérieur du bâtiment, d'autre part, une peau externe destinée à être orientée en direction de l'extérieur du bâtiment, et, d'autre part encore, des moyens pour raccorder lesdites peaux interne et externe entre elles, ces peaux étant positionnées en regard l'une de l'autre, de manière sensiblement parallèle et à une certaine distance l'une de l'autre en sorte de définir entre elles un espacement destiné à être comblé par un béton coulé entre ces peaux. Ce mur est caractérisé par le fait que, d'une part, la peau interne est constituée par une plaque de béton et, d'autre part, la peau externe est constituée par une plaque d'un parement d'habillage et/ou d'isolation préalablement équipée à l'aide desdits moyens de raccordement.To this end, the invention relates to a wall with integrated formwork for producing a wall of a building, more particularly an exterior wall, this wall comprising, on the one hand, an inner skin intended to be oriented inwards. the building, on the other hand, an outer skin to be oriented towards the outside of the building, and, secondly, means for connecting said inner and outer skins together, these skins being positioned opposite one of the other, substantially parallel and at a distance from one another so as to define between them a spacing to be filled by a concrete poured between these skins. This wall is characterized by the fact that, on the one hand, the inner skin is constituted by a concrete plate and, on the other hand, the outer skin is constituted by a plate of a cladding facing. and / or insulation previously equipped with said connecting means.

En fait, une telle plaque d'un parement d'habillage et/ou d'isolation est, au moins en partie, constituée par :

  • une plaque d'un matériau isolant, voire par une juxtaposition de plaques d'un matériau isolant ou ;
  • un élément support sur lequel est étalé une mince couche de béton ou ;
  • un élément en plâtre imputrescible ou encore ;
  • un élément réalisé à partir de bois ou analogue.
In fact, such a plate of a covering cladding and / or insulation is, at least in part, constituted by:
  • a plate of an insulating material, or even by a juxtaposition of plates of an insulating material or;
  • a support element on which is spread a thin layer of concrete or;
  • a piece of rotten plaster or else;
  • an element made from wood or the like.

La présente invention concerne, encore, un procédé pour la fabrication d'un tel mur à coffrage intégré.The present invention further relates to a method for manufacturing such an integrated form wall.

Selon une première variante d'un tel procédé :

  • l'on équipe au moins une partie de la peau externe, constituée par une plaque de parement d'habillage et/ou d'isolation, avec des moyens de raccordement ;
  • dans un moule, l'on coule du béton destiné, après séchage, à constituer une plaque de béton définissant la peau interne du mur à coffrage intégré ;
  • l'on noie dans ce béton une extrémité des moyens de raccordement équipant la peau externe ;
  • l'on assure le séchage du béton pour la formation d'une plaque de béton ;
  • l'on procède au démoulage du mur à coffrage intégré.
According to a first variant of such a method:
  • at least a portion of the outer skin, consisting of a cladding and / or insulation facing plate, is equipped with connection means;
  • in a mold, concrete is poured for drying, to form a concrete plate defining the inner skin of the integrated formwork wall;
  • embedding in this concrete one end of the connecting means equipping the outer skin;
  • the drying of the concrete is ensured for the formation of a concrete slab;
  • the molded integral wall is demolded.

Selon une seconde variante d'un tel procédé :

  • l'on équipe la peau externe, constituée par une plaque de parement d'habillage et/ou d'isolation, avec des moyens de raccordement solidaires d'un élément support ;
  • dans un moule contenant cette peau externe, l'on coule, par-dessus ledit élément support, au moins une couche de béton destinée, après séchage, à constituer une plaque de béton définissant la peau interne du mur à coffrage intégré ;
  • l'on assure le séchage du béton pour la formation d'une plaque de béton ;
  • l'on procède au démoulage du mur à coffrage intégré.
According to a second variant of such a method:
  • the external skin, consisting of a cladding and / or insulation facing plate, is equipped with connection means secured to a support element;
  • in a mold containing this outer skin, is poured over said support member, at least a concrete layer intended, after drying, to form a concrete plate defining the inner skin of the integrated formwork wall;
  • the drying of the concrete is ensured for the formation of a concrete slab;
  • the molded integral wall is demolded.

Les avantages de la présente invention consistent en ce qu'un tel mur à coffrage intégré comporte une seule et unique peau (interne) en béton alors que l'autre peau (externe) est constituée par une plaque de parement.The advantages of the present invention consist in that such an integrated formwork wall comprises a single and unique skin (inner) of concrete while the other (outer) skin is constituted by a facing plate.

Il en résulte que le temps de fabrication du mur est considérablement raccourci, notamment du fait de l'absence d'une deuxième peau en béton (temps de séchage du mur divisé par deux). L'absence d'une deuxième peau de béton permet, encore, d'éviter l'emploi d'un outil de retournement particulièrement onéreux et dont l'utilisation présente des risques pour le mur à coffrage intégré.As a result, the time of manufacture of the wall is considerably shortened, especially because of the absence of a second concrete skin (drying time of the wall divided by two). The absence of a second concrete skin makes it possible, again, to avoid the use of a particularly expensive turning tool whose use presents risks for the integrated formwork wall.

Le fait de réaliser un tel mur avec une seule peau de béton permet, également, de réduire la consommation d'énergie nécessaire pour la maturation du béton.The fact of making such a wall with a single concrete skin also makes it possible to reduce the energy consumption necessary for the maturation of the concrete.

En outre, le poids d'un mur à coffrage intégré selon l'invention est substantiellement réduit par rapport à celui des murs de l'état de la technique ce qui permet d'augmenter (notamment de doubler) les capacités de chargement d'un engin de transport (et ainsi de réduire le prix du transport) mais également de recourir à des engins de levage dont les capacités de levage et les dimensions sont plus modestes par rapport à ceux indispensables pour les murs de l'état de la technique.In addition, the weight of a wall with integrated formwork according to the invention is substantially reduced compared to that of the walls of the state of the art which makes it possible to increase (in particular doubling) the loading capacity of a transport unit (and thus reducing the cost of transport) but also the use of lifting gear with lifting capacities and dimensions that are smaller than those required for walls of the state of the art.

Dans le cas particulier d'une peau externe constituée en un matériau isolant, l'utilisation d'un mur conforme à l'invention permet un gain de temps substantiel et une réduction notable des coûts de l'isolation, ceci de par l'absence d'une opération de collage d'un isolant sur site que nécessitent les murs de l'état de la technique.In the particular case of an outer skin made of an insulating material, the use of a wall according to the invention allows a substantial saving of time and a significant reduction of the costs of the insulation, this by the absence an operation of bonding an insulator on site that requires the walls of the state of the art.

Finalement, le fait de recourir à un mur à coffrage intégré comportant une seule peau en béton permet, avantageusement, de réduire la quantité de matériau (béton) employé pour la fabrication d'un mur donc de réduire l'épaisseur de ce mur (de 12 à 16 cm contre 18 à 21 cm pour les murs de l'état de la technique) ce qui, pour une surface déterminée du bâtiment au sol, permet une augmentation de la surface intérieure utilisable (habitable) par rapport aux murs de l'état de la technique.Finally, the fact of using a formwork wall integrated with a single concrete skin advantageously allows to reduce the amount of material (concrete) used for the manufacture of a wall thus reducing the thickness of this wall (from 12 to 16 cm against 18 to 21 cm for the walls of the state of the art) which, for a given surface of the building on the ground, allows an increase of the usable interior surface (habitable) compared to the walls of the state of the art.

La présente invention concerne le domaine de l'industrie du bâtiment et, plus particulièrement, celui de la fabrication des mur à coffrage intégré utilisés dans le cadre de la construction d'un bâtiment pour la réalisation des murs d'un tel bâtiment.The present invention relates to the field of the building industry and, more particularly, that of the manufacture of integrated formwork walls used in the context of the construction of a building for the realization of the walls of such a building.

En fait, cette invention concerne, d'une part, un procédé de fabrication d'un tel mur à coffrage intégré 1 et, d'autre part, un mur à coffrage intégré 1 plus particulièrement obtenu par la mise en oeuvre de ce procédé. In fact, this invention relates, on the one hand, to a method of manufacturing such an integrated shuttering wall 1 and, on the other hand, to an integrated shuttering wall 1 more particularly obtained by the implementation of this method.

Si, dans la suite de la description, il sera, plus particulièrement, fait référence à un mur à coffrage intégré 1 pour la réalisation d'un mur extérieur d'un bâtiment correspondant au mode de réalisation le plus approprié de la présente invention, celle dernière n'y est cependant aucunement liée et peut, également, trouver une application dans la réalisation d'un mur intérieur.If, in the remainder of the description, reference will be made more particularly to an integrated form wall 1 for producing an exterior wall of a building corresponding to the most appropriate embodiment of the present invention, that the latter, however, is in no way connected and can also find an application in the realization of an interior wall.

De manière connue, un tel mur à coffrage intégré 1 comporte, d'une part, une peau interne 2 destinée à être orientée vers l'intérieur du bâtiment, d'autre part, une peau externe 3 destinée à être orientée en direction de l'extérieur du bâtiment et, d'autre part encore, des moyens 4 pour raccorder lesdites peaux interne 2 et externe 3 entre elles.In known manner, such integrated wall form 1 comprises, on the one hand, an inner skin 2 intended to be oriented towards the interior of the building, on the other hand, an outer skin 3 intended to be oriented towards the inside of the building. exterior of the building and, on the other hand, means 4 for connecting said inner skins 2 and outer 3 to each other.

A ce propos, on observera que lesdites peaux interne 2 et externe 3 sont positionnées en regard l'une 2 de l'autre 3, de manière sensiblement parallèle et à une certaine distance l'une 2 de l'autre 3 en sorte de définir entre elles un espacement 5. Cet espacement 5 est destiné à être comblé par un béton coulé entre ces peaux 2, 3 et à l'intérieur de cet espacement 5, ceci après que le mur à coffrage intégré 1 ait été mis en place sur site.In this respect, it will be observed that said inner skins 2 and outer skins 3 are positioned opposite one another 2, in a substantially parallel manner and at a certain distance one 2 of the other 3 so as to define between them a spacing 5. This spacing 5 is intended to be filled by a concrete poured between these skins 2, 3 and within this spacing 5, this after the integral form wall 1 has been set up on site .

Selon l'invention, la peau interne 2 est constituée par une plaque 6 de béton tandis que la peau externe 3 est constituée par une plaque 7 d'un parement d'habillage et/ou d'isolation.According to the invention, the inner skin 2 is constituted by a concrete plate 6 while the outer skin 3 is constituted by a plate 7 of a cladding and / or insulation facing.

A ce propos, on observera que ladite plaque de parement 7 est conçue en sorte d'assurer une fonction esthétique (fonction d'habillage) et/ou isolante (phonique et/ou thermique) mais aucunement une fonction de structure (comme une fonction de résistance) qui est assurée par la plaque de béton 6 de la peau interne 2 et, également et après durcissement, par la couche de béton coulée dans l'espacement 5 susmentionné.In this regard, it will be observed that said facing plate 7 is designed so as to ensure an aesthetic function (dressing function) and / or insulating (phonic and / or thermal) but not a function of structure (as a function of resistance) which is provided by the concrete plate 6 of the inner skin 2 and, also after curing, by the concrete layer cast in the above-mentioned spacing 5.

Selon un premier mode de réalisation visible figures 1 et 2, ladite plaque de parement 7 est, au moins en partie, constituée par une plaque d'un matériau isolant 8, voire par une juxtaposition de plaques d'un matériau isolant, notamment en polystyrène, plus particulièrement de type expansé ou extrudé.According to a first embodiment visible in FIGS. 1 and 2, said facing plate 7 is, at least in part, constituted by a plate of an insulating material 8, or even by a juxtaposition of plates of an insulating material, in particular made of polystyrene. more particularly of expanded or extruded type.

Un tel mode de réalisation consiste à réaliser un mur à coffrage intégré 1 dans lequel la peau externe 3 est, au moins en partie, constituée par au moins une plaque 8 définie en un matériau isolant. Ce mode de réalisation permet, avantageusement, de fabriquer le mur à coffrage intégré 1 directement en atelier avec les caractéristiques d'isolation et d'état de surface requis pour un mur externe d'un bâtiment, et permet, avantageusement, d'éviter le collage d'une plaque d'isolant sur une plaque de béton constituant la peau externe d'un mur de coffrage de l'état de la technique et, éventuellement, le traitement de surface d'un tel isolant après collage sur une telle plaque de béton.Such an embodiment consists in producing an integrated form wall 1 in which the outer skin 3 is, at least in part, constituted by at least one plate 8 defined in an insulating material. This embodiment advantageously makes it possible to manufacture the integrated formwork wall 1 directly in the workshop with the insulation and surface condition characteristics required for an external wall of a building, and advantageously makes it possible to avoid the bonding of an insulating plate on a concrete slab constituting the outer skin of a shuttering wall of the state of the art and, optionally, the surface treatment of such an insulator after bonding on such a slab of concrete.

Selon un autre mode de réalisation illustré figure 3, la plaque de parement 7 est, au moins en partie, constituée par un élément support 9 sur lequel est étalé, notamment par talochage ou analogue, une mince couche de béton 10.According to another embodiment illustrated in FIG. 3, the facing plate 7 is, at least in part, constituted by a support element 9 on which is spread, in particular by float or the like, a thin layer of concrete 10.

A ce propos, on observera que cet élément support 9 peut être constitué par au moins une plaque ajourée (notamment une plaque de tôle ou analogue), au moins une grille ou au moins un treillis, plus particulièrement un treillis fin (notamment dont les mailles mesurent de 2 à 6 mm). Un mode particulier de réalisation consiste en une juxtaposition de plusieurs plaques, grilles ou treillis pour former un tel élément support 9.In this regard, it will be observed that this support element 9 may be constituted by at least one perforated plate (in particular a sheet metal plate or the like), at least one grid or at least one lattice, more particularly a fine lattice (in particular with meshes measure from 2 to 6 mm). A particular embodiment consists of a juxtaposition of several plates, grids or lattices to form such a support element 9.

Une telle plaque ajourée, une telle grille ou un tel treillis sont, de préférence, réalisées en un matériau métallique.Such a perforated plate, such a grid or such a lattice are preferably made of a metallic material.

On remarquera que, dans ce cas, les moyens de raccordement 4 sont, de préférence, définis en un matériau métallique et sont rendus solidaires dudit élément support 9, de préférence, par soudure ou analogue.It will be noted that, in this case, the connecting means 4 are preferably defined in a metallic material and are secured to said support member 9, preferably by welding or the like.

En fait et selon un mode de réalisation particulier, une telle plaque de parement 7, comportant un élément support 9 sur lequel est étalé une mince couche de béton 10, peut, encore, comporter un élément d'isolation 11 recouvrant, extérieurement à la peau externe 3, cette mince couche de béton 10.In fact and according to a particular embodiment, such a facing plate 7, comprising a support element 9 on which is spread a thin layer of concrete 10, may further comprise an insulation element 11 covering, outside the outer skin 3, this thin layer of concrete 10.

Un tel élément d'isolation 11 peut, notamment, être constitué par au moins une plaque d'un matériau isolant ou analogue (notamment par une juxtaposition de telles plaques), plus particulièrement une plaque de polystyrène, par exemple de type expansé ou extrudé.Such an insulation element 11 may, in particular, be constituted by at least one plate of an insulating material or the like (in particular by a juxtaposition of such plates), more particularly a polystyrene plate, for example of expanded or extruded type.

Encore un autre mode de réalisation illustré figure 4 concerne une plaque de parement 7 constituée, au moins en partie, par un élément en plâtre imputrescible 12, notamment défini par au moins une plaque ou une juxtaposition de plaques en plâtre imputrescible.Yet another embodiment illustrated in Figure 4 relates to a facing plate 7 constituted, at least in part, by a rotproof plaster element 12, in particular defined by at least one plate or a juxtaposition of plaster rotproof plates.

Là encore, une telle plaque de parement 7 peut comporter, de manière additionnelle, un élément d'isolation 11 du type susmentionné et recouvrant, extérieurement à la peau externe 3, un tel élément en plâtre imputrescible 12.Again, such a facing plate 7 may additionally comprise an insulation element 11 of the aforementioned type and covering, externally to the outer skin 3, such rotproof plaster element 12.

Une telle plaque de parement 7 peut, également, comporter un élément d'habillage 13 (notamment constitué par une plaque ou une juxtaposition de plaques réalisées à partir de bois ou analogue) et recouvrant, là encore extérieurement à la peau externe 3, ledit élément en plâtre imputrescible 12.Such a facing plate 7 may also comprise a covering element 13 (in particular constituted by a plate or a juxtaposition of plates made from wood or the like) and covering, again externally to the outer skin 3, said element rotproof plaster 12.

Finalement et selon un mode de réalisation additionnel illustré figure 5, la plaque de parement 7 est, au moins en partie, constituée par un élément 14 réalisé à partir de bois ou analogue. Un tel élément 14 est, notamment, défini par au moins une plaque ou une juxtaposition de plaques réalisées à partir de bois ou analogue, une telle plaque étant, plus particulièrement, constituée par une plaque de bois ou par un panneau de particules de bois (plaque en CTBH par exemple).Finally and according to an additional embodiment illustrated in Figure 5, the facing plate 7 is at least partly constituted by an element 14 made from wood or the like. Such an element 14 is, in particular, defined by at least one plate or a juxtaposition of plates made from wood or the like, such a plate being, more particularly, constituted by a wooden plate or a wood particle board ( CTBH plate for example).

A ce propos, on observera qu'une telle plaque de parement 7 peut, là encore, comporter de manière additionnelle un élément d'isolation 11 et/ou un élément d'habillage 13 du type susmentionné, un tel élément (11 ; 13) recouvrant, là encore extérieurement à la peau externe 3, un élément 14 réalisé à partir de bois ou analogue.In this regard, it will be observed that such a facing plate 7 may, again, additionally comprise an insulation element 11 and / or a covering element 13 of the aforementioned type, such an element (11; 13). again covering, externally to the outer skin 3, an element 14 made from wood or the like.

En ce qui concerne les moyens 4 de raccordement, ceux-ci présentent, quel que soit le mode de réalisation de la peau externe 3 susmentionné, une première extrémité 15 rendue solidaire de la peau interne 2 en béton du mur 1.Regarding the connecting means 4, they have, regardless of the embodiment of the outer skin 3 mentioned above, a first end 15 secured to the inner skin 2 concrete wall 1.

Selon une première variante de réalisation illustrée figures 1 à 7b, cette première extrémité 15 est rendue solidaire de la peau interne 2 en étant noyée dans le béton de la plaque de béton 6 constituant cette peau interne 2. A ce propos, on observera que ces moyens de raccordement 4 comportent, alors, au niveau d'une portion 16 noyée dans le béton 6 de la peau interne 2 (notamment à proximité et/ou au niveau de ladite extrémité 15 susmentionnée), des moyens 17 assurant un ancrage dans ce béton.According to a first variant embodiment illustrated in FIGS. 1 to 7b, this first end 15 is made integral with the inner skin 2 by being embedded in the concrete of the concrete plate 6 constituting this inner skin 2. In this respect, it will be observed that these connection means 4 comprise, then, at a portion 16 embedded in the concrete 6 of the inner skin 2 (in particular near and / or at said end 15), means 17 ensuring anchoring in this concrete .

Cependant et selon une seconde variante de réalisation illustrée figures 8 à 8a, cette première extrémité 15 est rendue solidaire de la peau interne 2 en étant rendue solidaire (notamment par soudure) d'un élément support 9A recevant au moins une couche de béton 10A constituant, en combinaison avec cet élément support 9A, ladite peau interne 2.However, and according to a second variant embodiment illustrated in FIGS. 8 to 8a, this first end 15 is made integral with the inner skin 2 by being made integral (in particular by welding) with a support element 9A receiving at least one concrete layer 10A constituting , in combination with this support element 9A, said inner skin 2.

A ce propos, on observera que cet élément support 9A peut, là encore, être constitué par au moins une plaque ajourée, au moins une grille ou au moins un treillis du type susmentionné.In this regard, it will be observed that this support element 9A may, again, be constituted by at least one perforated plate, at least one grid or at least one lattice of the aforementioned type.

De plus et selon un mode préféré de réalisation, cet élément support 9A reçoit une première couche de béton de type traditionnel (de préférence d'épaisseur 5cm environ) ainsi que, par-dessus cette première couche de béton, une seconde couche de béton constituée par une chape autonivelante (de préférence en ciment d'épaisseur 0,5 cm) permettant d'assurer une finition lisse de la face externe (orientée vers l'intérieur du bâtiment) de la peau interne (2).In addition and according to a preferred embodiment, this support element 9A receives a first layer of traditional type of concrete (preferably about 5 cm thick) and, on top of this first layer of concrete, a second layer of concrete consisting of a self-leveling screed (preferably 0.5 cm thick cement) to ensure a smooth finish of the outer face (facing the interior of the building) of the inner skin (2).

Dans les modes de réalisation illustrés figures 1, 2 et 5 et correspondant à une peau externe 3 constituée, au moins en partie, par une plaque d'un matériau isolant 8 ou par un élément 14 réalisé à partir de bois ou analogue, ces moyens 4 de raccordement comportent une portion 20 traversant intégralement la plaque de parement 7 constituant la peau externe 3. Un tel mode de réalisation peut, également, être envisagé dans le cadre d'une plaque de parement 7 constituée, au moins en partie, par un élément en plâtre imputrescible 12 (solution non représentée).In the embodiments illustrated in FIGS. 1, 2 and 5 and corresponding to an outer skin 3 constituted, at least in part, by a plate of an insulating material 8 or by an element 14 made from wood or the like, these means 4 of connection comprise a portion 20 integrally through the facing plate 7 constituting the outer skin 3. Such an embodiment may also be considered in the context of a facing plate 7 constituted, at least in part, by a rotproof plaster element 12 (solution not shown).

Dans le mode de réalisation illustré figure 3 et correspondant à une peau externe 3 comportant un élément support 9 recevant une mince couche de béton 10, ces moyens 4 de raccordement comportent une seconde extrémité 18 rendue solidaire (notamment par soudure) de la face 19 d'une plaque du parement 7 (plus particulièrement de l'élément support 9 susmentionné) orientée en direction de la peau interne 2 et constituant la peau externe 3.In the embodiment illustrated in FIG. 3 and corresponding to an outer skin 3 comprising a support element 9 receiving a thin layer of concrete 10, these connecting means 4 comprise a second end 18 made integral (in particular by welding) with the face 19 of a plate of the facing 7 (more particularly of the above-mentioned support element 9) oriented in the direction of the inner skin 2 and constituting the outer skin 3.

Selon un autre mode de réalisation, ces moyens de raccordement 4 comportent une seconde extrémité 18 noyée dans un matériau constituant, au moins en partie, la plaque de parement 7 constituant la peau externe 3.According to another embodiment, these connecting means 4 comprise a second end 18 embedded in a material constituting, at least in part, the facing plate 7 constituting the outer skin 3.

Ainsi et tel qu'illustré figure 4 correspondant à une peau externe 3 constituée, au moins en partie, par un élément en plâtre imputrescible 12, ces moyens 4 de raccordement comportent une seconde extrémité 18 noyée dans le matériau (plâtre imputrescible) de la plaque de parement 7 constituant la peau externe 3.Thus, and as illustrated in FIG. 4 corresponding to an outer skin 3 constituted, at least in part, by a rotproof plaster element 12, these connecting means 4 comprise a second end 18 embedded in the material (rotten plaster) of the plate. facing 7 constituting the outer skin 3.

Cependant et selon un autre mode de réalisation de l'invention, la plaque de parement 7 (définissant la peau externe 3) présente au moins un réceptacle 23, défini au niveau d'une telle plaque 7 (plus particulièrement au niveau de la face 19 de la peau externe 3 orientée en direction de la peau interne 2), et contenant un matériau 24 à l'intérieur duquel est noyée la seconde extrémité 18 des moyens de raccordement 4, ceci pour une liaison par clavetage de cette plaque de parement 7 et des moyens de raccordement 4.However, according to another embodiment of the invention, the facing plate 7 (defining the outer skin 3) has at least one receptacle 23 defined at such a plate 7 (more particularly at the face 19 the outer skin 3 oriented towards the inner skin 2), and containing a material 24 inside which is embedded the second end 18 of the connecting means 4, this for a keyed connection of the facing plate 7 and connecting means 4.

On observera que le matériau 24 à l'intérieur duquel est noyée la seconde extrémité 18 des moyens de raccordement 4 est constitué par un liant durci, plus particulièrement du béton.It will be observed that the material 24 inside which is embedded the second end 18 of the connecting means 4 is constituted by a cured binder, more particularly concrete.

Selon une autre caractéristique, le réceptacle 23 est constitué par une rainure ou analogue, par exemple adoptant la forme d'une queue d'aronde ou analogue. Une telle rainure s'étend de manière longitudinale ou de manière transversale au niveau de la plaque de parement 7.According to another characteristic, the receptacle 23 is constituted by a groove or the like, for example adopting the shape of a dovetail or the like. Such a groove extends longitudinally or transversely at the level of the facing plate 7.

Selon un mode de réalisation particulier, une telle plaque de parement 7 présente pluralité de réceptacles 23, 23', 23" adoptant la forme de rainures s'étendant longitudinalement et/ou transversalement par rapport à une telle plaque 7. Un tel mode de réalisation permet de quadriller la plaque de parement 7 avec de telles rainures.According to a particular embodiment, such a facing plate 7 has a plurality of receptacles 23, 23 ', 23 "adopting the shape of grooves extending longitudinally and / or transversely with respect to such a plate 7. Such an embodiment allows to square the facing plate 7 with such grooves.

Il convient d'observer que la plaque de parement 7 comportant de tels réceptacles 23 peut être constituée, au moins en partie, par au moins un élément en plâtre imputrescible 12 ou, encore, par au moins un élément réalisé à partir de bois 14 ou analogue.It should be observed that the facing plate 7 comprising such receptacles 23 may be constituted, at least in part, by at least one rotproof plaster element 12 or, again, by at least one element made from wood 14 or similar.

Cependant et selon un mode préféré de réalisation de l'invention illustré figures 6, 6a et 8 à 8b, une telle plaque de parement 7 est constituée, au moins en partie, par au moins une plaque d'un matériau isolant 8. C'est, plus particulièrement, cette ou ces plaques d'un matériau isolant 8 qui présentent au moins un réceptacle 23, défini au niveau d'une telle plaque 8, et contenant un matériau 24 (du type susmentionné) à l'intérieur duquel est noyée la seconde extrémité 18 des moyens de raccordement 4.However, and according to a preferred embodiment of the invention illustrated in FIGS. 6, 6a and 8 to 8b, such a facing plate 7 is constituted, at least in part, by at least one plate of a 8. It is, more particularly, this or these plates of an insulating material 8 which have at least one receptacle 23, defined at such a plate 8, and containing a material 24 (of the aforementioned type) to inside which is embedded the second end 18 of the connecting means 4.

Un mode particulier de réalisation consiste en ce que cette ou ces plaques d'un matériau isolant 8 présentent une pluralité de réceptacles 23, 23', 23" adoptant la forme de rainures s'étendant longitudinalement et/ou transversalement par rapport à une telle plaque 8.A particular embodiment consists in that this or these plates of an insulating material 8 have a plurality of receptacles 23, 23 ', 23 "adopting the shape of grooves extending longitudinally and / or transversely with respect to such a plate 8.

Selon une autre caractéristique de l'invention, le mur 1 comporte, encore, au niveau d'une extrémité 18 des moyens de raccordement 4 coopérant avec la peau externe 3, des moyens 21 pour assurer une fixation de cette peau externe 3 sur ces moyens de raccordement 4 et, par conséquent, sur la peau interne 2.According to another characteristic of the invention, the wall 1 further comprises, at one end 18 of the connecting means 4 cooperating with the outer skin 3, means 21 for securing this outer skin 3 to these means. 4 and, therefore, on the inner skin 2.

De tels moyens de fixation 21 permettent, avantageusement, de maintenir la peau externe 3 à une distance déterminée de la peau interne 2, plus particulièrement lors de la coulée du béton dans l'espacement 5 entre ces deux peaux 2 ; 3 au cours de laquelle le béton coulé a tendance à prendre appui sur les peaux 2 ; 3 et à en provoquer l'éloignement.Such fastening means 21 advantageously allow the outer skin 3 to be maintained at a determined distance from the inner skin 2, more particularly during the pouring of the concrete in the spacing 5 between these two skins 2; 3 during which the cast concrete tends to bear on the skins 2; 3 and to provoke their removal.

A ce propos, on observera que, selon le mode de réalisation illustré figure 4 et correspondant à une peau externe 3 constituée par un élément en plâtre imputrescible 12, les moyens de fixation 21 sont constitués par des moyens d'ancrage des moyens de raccordement 4 dans le matériau de la peau externe 3.In this respect, it will be observed that, according to the embodiment illustrated in FIG. 4 and corresponding to an outer skin 3 constituted by a rotproof plaster element 12, the fastening means 21 are constituted by anchoring means of the connecting means 4. in the material of the outer skin 3.

Selon le mode de réalisation illustré figure 3 et correspondant à une peau externe 3 comportant un élément support 9 recevant une mince couche de béton 10, ces moyens de fixation 21 sont constitués par une soudure desdits moyens de raccordement 4 sur la face 19 de l'élément support 9.According to the embodiment illustrated in FIG. 3 and corresponding to an outer skin 3 comprising a support element 9 receiving a thin layer of concrete 10, these fixing means 21 are constituted by a welding of said connecting means 4 on the face 19 of the support element 9.

Selon les modes de réalisation illustrés figures 1, 2 et 5 et correspondant à une peau externe 3 constituée, au moins en partie, par une plaque d'un matériau isolant 8 ou par un élément 14 réalisé à partir de bois ou analogue, les moyens de fixation 21 sont constitués par des moyens d'accrochage des moyens de raccordement 4 à la face 22 de la peau externe 3 opposée à la face 19 orientée en direction de la peau interne 2.According to the embodiments illustrated in FIGS. 1, 2 and 5 and corresponding to an external skin 3 constituted, at least in part, by a plate of an insulating material 8 or by an element 14 made from wood or the like, the means fastening means 21 are constituted by means for fastening the connection means 4 to the face 22 of the outer skin 3 opposite the face 19 oriented in the direction of the inner skin 2.

Finalement et selon les modes de réalisation illustrés figures 6, 6a et 8 à 8b, de tels moyens de fixation 21 peuvent, encore, être constitués par des moyens de clavetage de l'extrémité 18 de ces moyens de raccordement 4 (réceptacle 23 contenant un matériau 24 à l'intérieur duquel est noyée l'extrémité 18 d'un moyen de raccordement 4).Finally, and according to the embodiments illustrated in FIGS. 6, 6a and 8 to 8b, such fastening means 21 may, again, be constituted by means for locking the end 18 of these connecting means 4 (receptacle 23 containing a material 24 inside which is embedded the end 18 of a connecting means 4).

Selon une caractéristique additionnelle, lesdits moyens de raccordement 4 sont constitués par des tiges métalliques, en fibre de verre ou en matière synthétique adoptant, notamment, la forme d'un clou, d'un tirant, d'un ancrage ou analogue.According to an additional feature, said connecting means 4 consist of metal rods, fiberglass or synthetic material adopting, in particular, the form of a nail, a tie rod, an anchor or the like.

Cependant et selon un autre mode de réalisation, de tels moyens de raccordement 4 peuvent, encore, adopter la forme d'une poutrelle connue en soi et comportant au moins deux tiges métalliques parallèles entre elles et reliées par une ossature de fils métalliques, plus particulièrement adoptant une forme en zig-zag. Un mode particulier de réalisation consiste en ce qu'une telle poutrelle comporte trois tiges métalliques disposées de manière à adopter la forme d'un triangle dont la base est rendue solidaire de la peau interne 2 (notamment en étant noyée dans le béton la constituant) tandis que le sommet de ce triangle est rendu solidaire de la peau externe 3 (figures 7 à 7b).However, according to another embodiment, such connecting means 4 can, again, take the form of a beam known per se and comprising at least two metal rods parallel to each other and connected by a frame of metal son, more particularly adopting a zig-zag shape. A particular embodiment consists in that such a beam comprises three metal rods arranged so as to adopt the shape of a triangle whose base is made integral with the inner skin 2 (in particular by being embedded in the concrete constituting it) while the top of this triangle is secured to the outer skin 3 (Figures 7 to 7b).

L'invention concerne, également, un procédé pour la fabrication d'un mur à coffrage intégré 1 pour la réalisation d'un mur d'un bâtiment (plus particulièrement un mur extérieur), ce mur 1 présentant les caractéristiques susmentionnées.The invention also relates to a method for manufacturing an integrated formwork wall 1 for producing a wall of a building (more particularly an exterior wall), this wall 1 having the above-mentioned characteristics.

En fait, selon une première variante, ce procédé consiste en ce que :

  • l'on équipe au moins une partie de la peau externe 3, constituée par une plaque de parement 7 d'habillage et/ou d'isolation, avec des moyens de raccordement 4 ;
  • dans un moule 25, l'on coule du béton destiné, après séchage, à constituer une plaque de béton 6 définissant la peau interne 2 du mur à coffrage intégré 1 ;
  • l'on noie dans ce béton une extrémité 15 des moyens de raccordement 4 équipant la peau externe 3 ;
  • l'on assure le séchage du béton pour la formation d'une plaque de béton 6 ;
  • l'on procède au démoulage du mur à coffrage intégré 1.
In fact, according to a first variant, this method consists in that:
  • at least a portion of the outer skin 3, consisting of a cladding plate 7 covering and / or insulation, is equipped with connection means 4;
  • in a mold 25, concrete is poured for, after drying, to form a concrete plate 6 defining the inner skin 2 of the integral form wall 1;
  • the concrete is embedded in one end 15 connecting means 4 fitted to the outer skin 3;
  • the drying of the concrete is ensured for the formation of a concrete slab 6;
  • the molded integral wall 1 is demolded.

En fait, lorsque l'on noie l'extrémité 15 des moyens de raccordement 4 dans le béton, l'on dispose ces moyens de raccordement 4 dans le moule 25, ceci avant ou, et de préférence, après avoir coulé ce béton dans le moule 25.In fact, when the end 15 of the connecting means 4 is embedded in the concrete, these connection means 4 are placed in the mold 25, before or, preferably, after pouring this concrete into the concrete. mold 25.

Selon une autre étape de ce procédé, avant de noyer l'extrémité 15 des moyens de raccordement 4 dans le béton, l'on équipe la plaque de parement 7 constituant la peau externe 3 (celle comportant un élément support 9 recevant une mince couche de béton 10) avec ces moyens de raccordement 4 en assurant la solidarisation (plus particulièrement par soudure) de ces derniers 4 (plus particulièrement de leurs extrémités 18) à la face 19 (plus particulièrement constituée par un élément support 9) de la plaque du parement 7 destinée à être orientée en direction de la peau interne 2.According to another step of this process, before drowning the end 15 of the connecting means 4 in the concrete, we equip the facing plate 7 constituting the outer skin 3 (that comprising a support member 9 receiving a thin layer of concrete 10) with these connecting means 4 ensuring the joining (more particularly by welding) of the latter 4 (more particularly of their ends 18) to the face 19 (more particularly constituted by a support member 9) of the facing plate 7 intended to be oriented in the direction of the inner skin 2.

Un tel mode de réalisation a été illustré figures 7 à 7c et consiste à noyer, dans le béton contenu dans un moule 25, l'extrémité 15 des moyens de raccordement 4 préalablement solidarisés à un élément support 9 (figure 7a). Le procédé consiste, ensuite, à étaler une mince couche de béton 10 sur cet élément support 9 (figure 7a) pour réaliser la plaque de parement 7.Such an embodiment has been illustrated in FIGS. 7 to 7c and consists in embedding, in the concrete contained in a mold 25, the end 15 of the connection means 4 previously secured to a support member 9 (FIG. 7a). The method then consists in spreading a thin layer of concrete 10 on this support element 9 (FIG. 7a) to produce the facing plate 7.

Tel que visible sur la figure 7b, ce procédé peut, de manière optionnelle, être poursuivi en disposant, par-dessus cette mince couche de béton 10, au moins une plaque d'un matériau isolant 8 (ou un élément réalisé à partir de bois ou encore un élément en plâtre imputrescible) pourvue de réceptacles 23 à l'intérieur desquels s'engouffre le béton de la couche mince 10, notamment par reflux, ceci pour une solidarisation de cette plaque 8 (ou d'un élément du type susmentionné) à la plaque de parement 7 (élément support 9 + couche de béton 10).As can be seen in FIG. 7b, this method may, optionally, be continued by placing, on top of this thin layer of concrete 10, at least one plate of an insulating material 8 (or an element made from wood or else a rotproof plaster element) provided with receptacles 23 inside which the concrete of the thin layer 10 engulfs, in particular by reflux, for the purpose of securing this plate 8 (or of an element of the aforementioned type) to the facing plate 7 (supporting element 9 + concrete layer 10).

Un autre mode de réalisation de ce procédé est applicable à une peau externe 3 au moins en partie constituée par un élément en plâtre imputrescible 12, par un élément en bois 14 ou par une plaque ou une juxtaposition de plaques d'un matériau isolant 8.Another embodiment of this method is applicable to an outer skin 3 at least partly constituted by a rotproof plaster element 12, a wooden element 14 or a plate or a juxtaposition of plates of an insulating material 8.

Dans ces cas de figure, le procédé consiste, avant de noyer une extrémité 15 des moyens de raccordement 4 dans le béton, à équiper la plaque de parement 7 constituant cette peau externe 3 avec ces moyens de raccordement 4 en noyant l'autre extrémité 18 de ces moyens de raccordement 4 dans un matériau 24 constituant, au moins en partie, cette peau externe 3 et constitué, notamment, par du plâtre imputrescible ou un liant durcissable (du type susmentionné).In these cases, the method consists, before drowning an end 15 of the connection means 4 in the concrete, to equip the facing plate 7 constituting the outer skin 3 with these connecting means 4 by drowning the other end 18 of these connection means 4 in a material 24 constituting, at least in part, this outer skin 3 and consisting, in particular, of rot-proof plaster or curable binder (of the aforementioned type).

Un tel mode de réalisation a été illustré figures 6 et 6a, à titre d'exemple pour une plaque de parement 7 au moins en partie constituée par une plaque en un matériau isolant 8 présentant au moins un réceptacle 23. Ce mode de réalisation nécessite, après avoir noyé l'extrémité 18 des moyens de raccordement 4 dans au moins un réceptacle 23 (notamment constitué par une rainure ou analogue, par exemple adoptant la forme d'une queue d'aronde ou analogue) contenant ledit matériau 24 (notamment constitué par un liant durcissable, plus particulièrement du béton) et après durcissement de ce dernier (figure 6), à retourner cette plaque de parement 7 (figure 6a) avant de noyer l'extrémité 15 de ces moyens de raccordement 4 dans le béton.Such an embodiment has been illustrated in FIGS. 6 and 6a, by way of example for a facing plate 7 at least partly constituted by a plate made of an insulating material 8 having at least one receptacle 23. This embodiment requires, after embedding the end 18 of the connection means 4 in at least one receptacle 23 (in particular constituted by a groove or the like, for example adopting the shape of a dovetail or the like) containing said material 24 (in particular constituted by a curable binder, more particularly concrete) and after hardening of the latter (Figure 6), to return the facing plate 7 (Figure 6a) before drowning the end 15 of these connection means 4 in the concrete.

Pour une peau externe 3 constituée, au moins en partie, par une plaque d'un matériau isolant 8 (ou une juxtaposition de plaques d'un matériau isolant) ou par un élément 14 réalisé à partir de bois ou analogue, voire encore par un élément en plâtre (12) imputrescible, le procédé peut, encore, consister en ce que, avant de noyer l'extrémité 15 des moyens de raccordement 4 dans le béton, l'on équipe la plaque de parement 7 constituant la peau externe 3 avec ces moyens de raccordement 4 en transperçant cette peau externe 3 à l'aide de ces moyens de raccordement 4.For an outer skin 3 formed, at least in part, by a plate of an insulating material 8 (or a juxtaposition of plates of an insulating material) or by an element 14 made from wood or the like, or even by a plaster element (12) imputrescible, the method can, again, be that, before drowning the end 15 of the connection means 4 in the concrete, we equip the facing plate 7 constituting the outer skin 3 with these connecting means 4 by piercing this outer skin 3 with the aid of these connecting means 4.

Selon une autre variante du procédé conforme à l'invention, ce procédé peut, encore, consister en ce que :

  • l'on équipe la peau externe 3, constituée par une plaque de parement 7 d'habillage et/ou d'isolation, avec des moyens de raccordement 4 solidaires (notamment par soudure) d'un élément support 9A;
  • dans un moule contenant cette peau externe 3, l'on coule, par-dessus ledit élément support 9A, au moins une couche de béton 10A destinée, après séchage, à constituer une plaque 6 de béton définissant la peau interne 2 du mur 1 à coffrage intégré ;
  • l'on assure le séchage du béton pour la formation d'une plaque de béton 6 ;
  • l'on procède au démoulage du mur 1 à coffrage intégré.
According to another variant of the process according to the invention, this process can, again, consist in that:
  • the outer skin 3, constituted by a cladding plate 7 for covering and / or insulating, is equipped with connection means 4 integral (in particular by welding) with a support member 9A;
  • in a mold containing this outer skin 3, over said support element 9A, at least one concrete layer 10A is poured, after drying, to form a concrete plate 6 defining the inner skin 2 of the wall 1 to integrated formwork;
  • the drying of the concrete is ensured for the formation of a concrete slab 6;
  • the molded wall 1 is demolded.

Cette variante a été illustrée figures 8 à 8b pour une paroi externe 3 constituée par une plaque de parement 7 définie par au moins une plaque d'un matériau isolant 8 sachant que cette variante n'y est nullement limitée et peut aussi s'appliquer pour tout autre type de plaque de parement 7 décrit ci-dessus.This variant has been illustrated in FIGS. 8 to 8b for an external wall 3 constituted by a facing plate 7 defined by at least one plate of an insulating material 8, knowing that this variant is in no way limited thereto and can also be applied for any other type of facing plate 7 described above.

De plus, cette variante a été illustrée pour une plaque de parement 7 comportant des réceptacles 23 destinés à contenir un matériau 24 dans lequel sont noyées les extrémités 18 des moyens de raccordement 4, sachant que cette variante n'est aucunement limitée à ce mode de réalisation mais peut, également, s'appliquer à tout autre mode de solidarisation des moyens de raccordement 4 à la peau externe 3 décrit ci-dessus.In addition, this variant has been illustrated for a facing plate 7 having receptacles 23 intended to contain a material 24 in which are embedded the ends 18 of the connection means 4, knowing that this variant is not limited to this mode of embodiment but may also apply to any other method of securing the connecting means 4 to the outer skin 3 described above.

Finalement, dans le cas où la plaque de parement 7 comporte de manière additionnelle un élément d'isolation 11 et/ou un élément d'habillage 13, ce procédé peut, encore, consister à mettre en place un tel élément (11, 13), soit avant de noyer l'extrémité 15 des moyens de raccordement dans le béton, soit pendant ou après séchage du béton de la peau interne 2, soit encore sur site.Finally, in the case where the facing plate 7 additionally comprises an insulating element 11 and / or a covering element 13, this method may also consist in setting up such an element (11, 13). or before drowning the end 15 of the connection means in the concrete, either during or after drying of the concrete of the inner skin 2, or still on site.

Bien que l'invention ait été décrite à propos d'une forme de réalisation particulière, il est bien entendu qu'elle n'y est nullement limitée et qu'on peut y apporter diverses modifications de formes, de matériaux et de combinaisons de ces divers éléments sans pour cela s'éloigner du cadre et de l'esprit de l'invention.Although the invention has been described with respect to a particular embodiment, it is understood that it is in no way limited and that various modifications of shapes, materials and combinations thereof can be made. various elements without departing from the scope and spirit of the invention.
