Description

L'invention se rapporte à un mur porteur isolant thermique pour construction préfabriquée par rapport à son épaisseur, conçu notamment pour le chauffage électrique. The invention relates to a thermal insulating load-bearing wall for prefabricated construction with respect to its thickness, designed in particular for electric heating.

L'utilisation du chauffage électrique implique, pour des raisons d'économie, un degré d'isolation élevé. The use of electric heating implies, for reasons of economy, a high degree of insulation.

Ces normes d'isolation imposées par la loi dans le cas du chauffage électrique sont conseillées et fréquemment adoptées par les constructeurs dans les constructions d'habitations, notamment les maisons individuelles, quels que soient le mode et l'énergie de chauffage. These insulation standards imposed by law in the case of electric heating are advised and frequently adopted by manufacturers in the construction of dwellings, in particular individual houses, whatever the mode and energy of heating.

Dans les maisons traditionnelles, il arrive encore que les entrepreneurs adoptent l'isolation intérieure par interposition de plaques isolantes prises entre les murs extérieurs et des contre-cloisons. In traditional houses, it still happens that contractors adopt interior insulation by interposing insulating plates taken between the exterior walls and counter-partitions.

Cette solution, fort coûteuse en main-d'œuvre et en matériaux, est complètement dépassée aujourd'hui et, de ce fait, assez rarement employée. On lui préfère des panneaux isolants comportant une surface finie côté intérieur. Dans la maison préfabriquée, il n'est pas possible de concevoir ou de prévoir des interventions de gros œuvre en dehors de l'assemblage de base. La couche isolante doit être intégrée au mur ou pan de mur dès la fabrication. This solution, which is very costly in terms of labor and materials, is completely out of date today and, therefore, quite rarely used. We prefer insulating panels with a finished surface on the inside. In the prefabricated house, it is not possible to design or plan structural work outside of the basic assembly. The insulating layer must be integrated into the wall or section of wall at the time of manufacture.

En préfabrication, on a déjà proposé des planchers rendus ther-miquement isolants par collage d'une couche de matière isolante en sous-face. In prefabrication, floors have already been made thermally insulating by gluing a layer of insulating material on the underside.

Des murs isolants préfabriqués existent également. Ces murs sont formés de matière isolante rapportés sur les faces intérieures. Prefabricated insulating walls also exist. These walls are formed of insulating material attached to the interior faces.

L'intégration de l'isolation aux murs n'est pas du tout résolue correctement, ce qui ne permet pas de garantir le maintien de l'isolation dans le temps. The integration of the insulation into the walls is not at all resolved correctly, which does not guarantee the maintenance of the insulation over time.

Par ailleurs, le problème de la continuité de l'isolation au droit des jonctions et des moyens d'assemblage est mal réglé. In addition, the problem of the continuity of the insulation at the right of the junctions and the means of assembly is badly regulated.

Il subsiste en effet des ponts thermiques indésirables, en général d'étendue importante. There are indeed undesirable thermal bridges, generally of large extent.

La rupture d'isolation ainsi créée entraîne des désagréments de confort et d'esthétique, car elle engendre la formation de zones froides, mais aussi de points de faiblesse et de fissuration dans la construction. The insulation breakage thus created leads to inconvenience in terms of comfort and aesthetics, because it causes the formation of cold zones, but also points of weakness and cracking in the construction.

Le mur préfabriqué selon l'invention, défini à la revendication 1, apporte des améliorations sensibles à l'isolation des maisons individuelles et à leur construction. The prefabricated wall according to the invention, defined in claim 1, provides appreciable improvements in the insulation of individual houses and in their construction.

La description qui suit fait ressortir toutes les caractéristiques techniques de l'invention. Celle-ci est effectuée à titre d'exemple non limitatif en référence au dessin annexé dans lequel: The description which follows highlights all the technical characteristics of the invention.

la fig. 10 est une vue en coupe verticale sur plafond. fig. 10 is a view in vertical section on the ceiling.

Un mur préfabriqué selon l'invention présente la configuration générale telle qu'illustrée par la fig. 1. A prefabricated wall according to the invention has the general configuration as illustrated in FIG. 1.

Il est appelé à constituer les murs extérieurs d'une maison individuelle, à hauteur d'étage. It is called upon to constitute the external walls of an individual house, at the height of the floor.

Son profil transversal se compose d'une succession d'arches rectangulaires ouvertes telles que 1, s'étendant sur toute la hauteur du mur. Its transverse profile consists of a succession of open rectangular arches such as 1, extending over the entire height of the wall.

Elle se termine sur le chant du mur par une rainure 2 à fond plat de profil en V formant coffrage pour le joint de scellement 3 en béton. It ends on the edge of the wall with a groove 2 with a flat V-shaped bottom forming formwork for the sealing joint 3 in concrete.

Chaque chant comporte sur toute la hauteur du mur, au droit des rainures 2, côté extérieur, un évidement rectangulaire 4 pourvu d'une platine de raccordement 5. Each edge has over the entire height of the wall, at the grooves 2, on the outside, a rectangular recess 4 provided with a connection plate 5.

Les arches 1 délimitent avec une plaque de fermeture 6 côté extérieur des alvéoles 7 remplies de matière isolante 8 telle que du polystyrène expansé ou un vide. The arches 1 delimit with a closure plate 6 on the outside of the cells 7 filled with insulating material 8 such as expanded polystyrene or a vacuum.

Le mur comporte une armature dense formée de tiges métalliques 9 verticales au niveau des pieds 10 des arches 1 raccordées entre elles par des traverses horizontales disposées à intervalles réguliers sur toute la hauteur du mur. Ces traverses sont reliées entre elles par des tiges verticales extérieures noyées dans une plaque de béton 12 formant la face extérieure. Cette plaque est renforcée intérieurement par un treillis métallique 12. Un treillis analogue 14 arme la face avant. The wall has a dense reinforcement formed of vertical metal rods 9 at the level of the feet 10 of the arches 1 connected to one another by horizontal crosspieces arranged at regular intervals over the entire height of the wall. These crosspieces are connected together by vertical external rods embedded in a concrete plate 12 forming the external face. This plate is internally reinforced by a metal mesh 12. An analogous mesh 14 arms the front face.

Un couple de tiges horizontales tel que 15, en acier, connu sous la dénomination TOR, par exemple de diamètre 8 mm, renforce le mur selon l'invention en partie haute et basse. A pair of horizontal rods such as 15, made of steel, known under the name TOR, for example 8 mm in diameter, strengthens the wall according to the invention in the upper and lower parts.

Ce mur présente, au niveau de l'extrémité de chaque pied d'arche ou chaque arche de rang pair, une boucle de levage telle que 16 solidarisée à l'armature intérieure pour la manutention et la mise en place sur le chantier. This wall has, at the end of each arch foot or each arch of even rank, a lifting loop such as 16 secured to the interior frame for handling and installation on the site.

Il possède une paroi intérieure lisse prête à recevoir les revêtements muraux et une face extérieure uniforme pour la projection d'un revêtement extérieur. It has a smooth interior wall ready to receive wall coverings and a uniform exterior face for the projection of an exterior covering.

Le mur préfabriqué isolant ainsi constitué possède une épaisseur totale de 25 cm. The insulating prefabricated wall thus formed has a total thickness of 25 cm.

Cette épaisseur est la plus petite que l'on connaisse pour des murs porteurs de maisons individuelles. This thickness is the smallest that we know for load-bearing walls of individual houses.

Après avoir décrit la structure générale du mur objet de la présente invention, on examinera ses raccordements avec l'élément de plancher, avec les fondations, avec le mur supérieur et son ancrage sur la charpente. After having described the general structure of the wall which is the subject of the present invention, we will examine its connections with the floor element, with the foundations, with the upper wall and its anchoring on the frame.

Ces caractéristiques sont représentées en fig. 4 et 5. These characteristics are shown in fig. 4 and 5.

Dans un deuxième temps, on décrira les assemblages horizontaux. In a second step, we will describe the horizontal assemblies.

La coupe verticale 4 laisse apparaître en partie haute un piton d'ancrage 17 fixant la charpente 18 solidarisé à une platine haute 19 prévue dans la partie supérieure du mur, ou scellé dans la paroi intérieure de l'élément. The vertical section 4 reveals in the upper part an anchor bolt 17 fixing the frame 18 secured to a high plate 19 provided in the upper part of the wall, or sealed in the inner wall of the element.

La liaison entre deux éléments verticaux est assurée par un joint de compression autocollant 20. L'immobilisation verticale est réalisée par une platine élément 21 ancrée dans la partie basse du mur et par une platine de chaînage 22 ou de fondation 23 métalliques solidarisées entre elles par soudage. Les platines de chaînage ou de fondations sont immobilisées par un crochet 24 pris dans la masse. The connection between two vertical elements is ensured by a self-adhesive compression joint 20. The vertical immobilization is carried out by an element plate 21 anchored in the lower part of the wall and by a metal chain 22 or foundation plate 23 secured to each other by welding. The chain plates or foundations are immobilized by a hook 24 taken in the mass.

La jonction entre le mur porteur et le plancher de premier étage est réalisée par le coulage d'un périmètre sous la forme d'une pou-, trelle de béton 25 formant chaînage. The junction between the load-bearing wall and the first floor is made by pouring a perimeter in the form of a concrete trellis 25 forming a chain.

L'immobilisation résulte de l'imbrication des armatures en tige d'acier. Au moins une armature longitudinale de chaînage 26 passe dans les boucles de levage 16 des murs porteurs et les boucles de levage analogues 27 des éléments de plancher 28. Immobilization results from the interweaving of steel rod reinforcements. At least one longitudinal chaining frame 26 passes through the lifting loops 16 of the load-bearing walls and the similar lifting loops 27 of the floor elements 28.

Les assemblages horizontaux sont du type à boulonnage par boulons tels que 29 et joint de scellement en béton 3. The horizontal connections are of the bolt-on type such as 29 and concrete sealing joint 3.

L'assemblage est complété côté intérieur par la solidarisation des platines verticales 5. Celles-ci possèdent, au droit des cloisons, un rappel métallique 30 sous forme de platine complémentaire 31 fortement ancrée sur les parois de cloison. The assembly is completed on the interior side by securing the vertical plates 5. These have, to the right of the partitions, a metallic return 30 in the form of an additional plate 31 strongly anchored on the partition walls.

L'assemblage aux angles 32 s'effectue d'une façon analogue, par boulonnage et formation d'un joint de scellement en béton. The assembly at the angles 32 is carried out in a similar manner, by bolting and forming a concrete sealing joint.

La conformation technique en extrémité de mur est telle que représentée dans la fig. 8. La solidarisation par platine s'effectue dans l'angle de la partie en retrait 33. The technical configuration at the end of the wall is as shown in fig. 8. The connection by plate takes place in the corner of the recessed part 33.

La coupe sur fenêtre représentée en fig. 9 montre la structure 5 particulière du mur selon l'invention au niveau d'une ouverture à l'extérieur. Elle comporte, en partie inférieure, des conformations en profilés du type jet d'eau 34 et 35 et, en partie supérieure, une lisse 36 et une structure supérieure 37 comportant une armature spéciale 38 formant linteau. The section on window shown in fig. 9 shows the particular structure 5 of the wall according to the invention at an opening to the outside. It comprises, in the lower part, shaped conformations of the water jet type 34 and 35 and, in the upper part, a heald 36 and an upper structure 37 comprising a special frame 38 forming a lintel.

10 La dernière figure représente la jonction d'un élément de mur avec le plafond. Un profilé annexe 39 supporte, par son périmètre, une couche de plâtre en toilé 40. 10 The last figure represents the junction of a wall element with the ceiling. An annex profile 39 supports, by its perimeter, a layer of plaster in canvas 40.

La partie supérieure est fortement isolée par l'intermédiaire de 15 plusieurs couches 41 de matière isolante. The upper part is highly insulated by means of several layers 41 of insulating material.
