Description

1 La présente invention concerne un élément de paroi en bois destiné à former un mur d'un bâtiment à ossature bois, un plancher ou une charpente. Les ossatures en bois comportent une structure porteuse sur laquelle sont fixés des panneaux de contreventement. La structure porteuse est généralement constituée de poutres en bois massif de part et d'autre de chacune desquelles sont fixés respectivement un panneau de contreventement et un panneau de fermeture du caisson ou une membrane. Le bois massif est de plus en plus coûteux et son poids rend les manipulations difficiles sur chantier. En outre, l'utilisation de bois massif s'avère contraignante sur le plan technique. En effet, il est demandé aux constructeurs de fournir des bâtiments présentant des performances énergétiques de plus en plus élevées, c'est-à-dire que les bâtiments doivent être isolés thermiquement de manière que leur chauffage et leur climatisation soient peu gourmands en énergie. Une telle isolation nécessite des murs épais pour disposer d'une masse d'air importante jouant le rôle d'isolant ou pour disposer d'un espace suffisant dans le mur pour y loger une couche d'isolant. Or, les poutres en bois massif ayant une épaisseur suffisante pour la réalisation de tels murs sont coûteuses et lourdes, et leur utilisation dans cette application entraîne une surconsommation inutile de matière. En outre, de telles poutres en bois massif vont constituer des ponts thermiques qui dégradent les performances énergétiques du bâtiment. The present invention relates to a wooden wall element for forming a wall of a timber frame building, a floor or a framework. The wooden frames have a supporting structure on which bracing panels are fixed. The supporting structure is generally made of solid wood beams on either side of each of which are respectively fixed a bracing panel and a closure panel of the box or a membrane. Solid wood is increasingly expensive and its weight makes handling difficult on site. In addition, the use of solid wood is technically binding. Manufacturers are asked to supply buildings with increasingly high energy performance, ie buildings must be thermally insulated so that their heating and air conditioning are energy efficient. Such insulation requires thick walls to have a large air mass acting as insulation or to have sufficient space in the wall to accommodate a layer of insulation. However, the solid wood beams having a thickness sufficient for the realization of such walls are expensive and heavy, and their use in this application leads to an unnecessary overconsumption of material. In addition, such solid wood beams will constitute thermal bridges that degrade the energy performance of the building.

Il est connu des poutres comportant deux longerons ayant des faces en regard dans lesquelles sont ménagés des logements pour des extrémités d'entretoises maintenant les deux longerons à une distance prédéterminée. Ces poutres permettent la réalisation de murs épais en limitant la création de ponts thermiques 2 mais sont toutefois coûteuses à fabriquer et nécessitent un process industriel et des équipements spécifiques. Un but de l'invention est de fournir un moyen permettant d'obtenir de manière simple et peu onéreuse des parois susceptibles de présenter de bonnes performances thermiques réalisables sur les équipements courants de la filière bois. A cet effet, on prévoit, selon l'invention, un élément de paroi comportant une structure porteuse et un panneau de contreventement fixé sur la structure porteuse, caractérisé en ce que la structure porteuse comprend au moins une poutre comportant un longeron porteur fixé au panneau de contreventement et un longeron additionnel parallèle au longeron porteur et relié à celui-ci par un panneau écarteur qui s'étend perpendiculairement au panneau de contreventement et qui possède deux portions longitudinales opposées fixées à plat respectivement contre une face longitudinale du longeron porteur et une face longitudinale du longeron additionnel. Ainsi, les poutres ont une structure simple qui peut être fabriquée pour un coût raisonnable. En outre, les deux longerons sont réunis par un voile écarteur présentant par définition une épaisseur relativement faible qui limite les transferts de chaleur. Selon un mode de réalisation particulier, la structure porteuse comprend plusieurs poutres reliées entre elles par au moins une traverse et, de préférence, au moins deux traverses reliant les poutres entre elles à chaque extrémité de celles-ci. La structure porteuse présente ainsi une bonne résistance mécanique. Avantageusement, le panneau écarteur est fixé aux longerons par agrafage ou clouage. It is known beams having two longitudinal members having facing faces in which are formed housing for ends of spacers maintaining the two longitudinal members at a predetermined distance. These beams allow the production of thick walls by limiting the creation of thermal bridges 2 but are however expensive to manufacture and require an industrial process and specific equipment. An object of the invention is to provide a means for obtaining in a simple and inexpensive way walls likely to have good thermal performance achievable on current equipment of the wood industry. For this purpose, there is provided, according to the invention, a wall element comprising a supporting structure and a bracing panel fixed to the supporting structure, characterized in that the supporting structure comprises at least one beam comprising a support beam fixed to the panel bracing and an additional spar parallel to the carrier spar and connected thereto by a spacer panel which extends perpendicularly to the bracing panel and which has two opposite longitudinal portions fixed flat respectively against a longitudinal side of the carrier spar and a face longitudinal of the additional spar. Thus, the beams have a simple structure that can be manufactured for a reasonable cost. In addition, the two longitudinal members are joined by a spacer sail having by definition a relatively small thickness which limits the heat transfer. According to a particular embodiment, the support structure comprises several beams interconnected by at least one cross member and, preferably, at least two cross members connecting the beams together at each end thereof. The supporting structure thus has good mechanical strength. Advantageously, the spacer panel is fixed to the longitudinal members by stapling or nailing.

Ce mode de fixation est simple, économique et fiable. De préférence, les longerons ont des sections rectangulaires et, avantageusement, le longeron porteur a une section double de celle du longeron additionnel. This method of attachment is simple, economical and reliable. Preferably, the longitudinal members have rectangular sections and, advantageously, the carrier spar has a double section of that of the additional spar.

Les longerons sont alors aisément réalisables par des moyens d'usinage traditionnels. En outre, à partir d'un élément en bois unique, il est possible de réaliser un longeron porteur en utilisant l'élément de bois tel quel ou deux longerons additionnels en sciant l'élément de bois dans le sens de la longueur. D'autres caractéristiques et avantages de l'invention ressortiront à la lecture de la description qui suit de modes de réalisation particuliers, non limitatifs de l'invention. The rails are then easily achievable by conventional machining means. In addition, from a single wooden element, it is possible to realize a carrier spar using the wooden element as such or two additional longitudinal members by sawing the wood element in the lengthwise direction. Other characteristics and advantages of the invention will emerge on reading the following description of particular, non-limiting embodiments of the invention.

Il sera fait référence aux dessins annexés, parmi lesquels : - la figure 1 est une vue en coupe transversale d'une poutre conforme à l'invention, - la figure 2 est une vue de face, avec écorché, d'un mur constitué d'éléments de parois conforme à l'invention, - la figure 3 est une vue en coupe selon la ligne III-III de ce mur, - la figure 4 est une vue en coupe transversale d'un plancher constitué d'éléments de paroi conformes à l'invention, - la figure 5 est une vue en coupe transversale d'une portion de toiture constituée d'éléments de paroi conformes à l'invention, - la figure 6 est un schéma illustrant la fabrication des poutres conformes à l'invention. En référence aux figures, l'invention concerne un élément de paroi, généralement désigné en 1, comportant une structure porteuse 2 et un panneau de contreventement 3 fixé sur la structure porteuse 2. 3 4 La structure porteuse 2 comprend des poutres généralement désignées en 4 et deux traverses 5 reliant les poutres 4 entre elles à chaque extrémité de celles-ci. Reference is made to the accompanying drawings, in which: FIG. 1 is a cross-sectional view of a beam according to the invention, FIG. 2 is a front view, with cutaway, of a wall consisting of 3 is a sectional view along the line III-III of this wall; FIG. 4 is a cross-sectional view of a floor consisting of conformal wall elements; FIG. 5 is a cross-sectional view of a roof portion consisting of wall elements according to the invention; FIG. 6 is a diagram illustrating the manufacture of the beams according to the invention; . Referring to the figures, the invention relates to a wall element, generally designated 1, comprising a supporting structure 2 and a bracing panel 3 fixed on the supporting structure 2. 3 4 The carrier structure 2 comprises beams generally designated 4 and two cross members 5 connecting the beams 4 to each other at each end thereof.

Chaque poutre 4 comporte un longeron porteur 6 auquel est agrafé le panneau de contreventement 3 et un longeron additionnel 7 parallèle au longeron porteur 6 et relié au longeron porteur 6 par un panneau (ou voile) écarteur 8. Le panneau écarteur 8 s'étend perpendiculairement au panneau de contreventement 3 et possède deux portions longitudinales opposées fixées à plat respectivement contre une face longitudinale 6.a du longeron porteur 6 et une face longitudinale 7.a du longeron additionnel 7. Le panneau écarteur 8 est fixé au longeron porteur 6 et au longeron additionnel 7 par agrafage. Le panneau écarteur 8 a une largeur comprise entre 200 et 420 mm par exemple. Un panneau de fermeture de caisson ou une membrane 11 est fixé en utilisation aux longerons additionnels 7 parallèlement au panneau de contreventement 3. Les longerons 6, 7 et les traverses 5 sont en bois massif. Les panneaux 3, 11 sont ici des panneaux de bois à lamelles minces orientées dits OSB (pour oriented strand board ) ou tout autre panneau utilisé pour une construction à ossature bois. Les longerons 6, 7 ont des sections rectangulaires. Le longeron porteur 6 a ici une section double de celle du longeron additionnel 7. La fabrication des poutres 4 est illustrée sur la figure 6. Des longerons A,B, de section égale à celle des longerons porteurs 6 sont disposés sur une table 100 (étape 1) de manière à avoir deux longerons A accolés puis un longeron B écarté du longeron A le plus proche d'une distance correspondant à la distance devant séparer un longeron porteur 6 d'un longeron additionnel 7, puis à la même distance, à nouveau deux longerons A accolés et ainsi de suite (l'écartement est par exemple maintenu au 5 moyen de gabarits). Les longerons A, B sont ensuite recouverts d'un panneau C (étape 2) qui est agrafé sur chaque longeron A, B. Le panneau C est agrafé au longeron B au moyen de deux lignes d'agrafes parallèles. Le panneau C a de préférence des dimensions standards, par exemple 2500 x 1196 mm ou 2800 x 1250 mm. Le panneau C est ensuite découpé (étape 3) à intervalles réguliers parallèlement aux longerons de telle manière qu'un trait de coupe passe entre les longerons A de chaque paires de longerons A et un trait de coupe sépare chaque longeron B en deux longerons identiques. En référence plus particulièrement aux figures 2 et 3, l'élément de paroi est disposé verticalement pour constituer un mur. Les poutres 4 sont verticales et les traverses 5 sont horizontales. Le panneau de contreventement 3 est tourné vers l'extérieur ou l'intérieur. De préférence, les poutres 4 sont espacées d'une distance comprise entre 400 et 600 mm par exemple. Les éléments de paroi 1, sans le panneau de fermeture du caisson 11, sont disposés les uns à côté des autres. De préférence, le panneau de contreventement 3 de chaque élément de paroi 1 a un bord longitudinal en saillie du longeron porteur 6 auquel il est fixé et un bord longitudinal en retrait du longeron porteur 6 auquel il est fixé. Ainsi, lorsque deux éléments de parois 1 sont accolés, le bord en saillie du panneau de contreventement 3 d'un des éléments de paroi 1 peut être fixé sur la partie de longeron porteur 6 laissée 6 découverte par le bord longitudinal en retrait du panneau de contreventement 3 de l'autre élément de paroi 1. Un matériau isolant thermiquement 9 est disposé dans les cavités délimitées par la structure porteuse 2 et les panneaux de contreventement 3 et les panneaux de fermeture du caisson 11 sont fixés sur les longerons additionnels 7. Le panneau de contreventement 6 a une épaisseur de 9 à 18 mm et le panneau de fermeture du caisson 11 a une épaisseur de 9 à 60 mm. Les panneaux 6 et 11 peuvent avoir un bord rainuré et un bord bouveté pour faciliter la mise en place des éléments de paroi 1 côte-à-côte. L'élément de paroi peut également être utilisé pour la réalisation d'une cloison. En référence à la figure 4, l'élément de paroi 1 est utilisé en tant que plancher. Le longeron porteur 6 est alors dimensionné comme une solive classique et l'espacement des poutres 4 est calculé de la même manière que pour des solives classiques. Le longeron porteur 6 a des extrémités en saillie du longeron additionnel 7 pour prendre appui sur des murs porteurs, des poutres ou des corbeaux. Le panneau de contreventement 3 formera la surface supérieure du plancher ainsi constitué. Des entretoises 10 peuvent être montées en cas de besoin entre le longeron porteur 6 et le longeron additionnel 7 pour rigidifier la poutre 4 en flexion. Each beam 4 comprises a carrier spar 6 to which is stapled the bracing panel 3 and an additional spar 7 parallel to the carrier spar 6 and connected to the carrier spar 6 by a panel (or sail) retractor 8. The spacer panel 8 extends perpendicularly to the bracing panel 3 and has two opposite longitudinal portions fixed flat respectively against a longitudinal face 6.a of the carrier spar 6 and a longitudinal face 7.a of the additional spar 7. The spacer panel 8 is fixed to the carrier spar 6 and to the additional spar 7 by stapling. The spacer panel 8 has a width of between 200 and 420 mm for example. A box closure panel or a membrane 11 is attached in use to the additional rails 7 parallel to the bracing panel 3. The rails 6, 7 and the cross members 5 are solid wood. The panels 3, 11 are here thin oriented wood panels called OSB (oriented oriented strip) or any other panel used for a timber frame construction. The longitudinal members 6, 7 have rectangular sections. The carrier spar 6 here has a double section of that of the additional spar 7. The manufacture of the beams 4 is illustrated in FIG. 6. Spacers A, B, of section equal to that of the carrying spars 6 are arranged on a table 100 ( step 1) so as to have two side members A contiguous and a side member B separated from the side member A closest to a distance corresponding to the distance to separate a carrier spar 6 from an additional spar 7, then at the same distance, to again two beams A contiguous and so on (the spacing is for example maintained by means of jigs). The longitudinal members A, B are then covered with a panel C (step 2) which is stapled on each beam A, B. The panel C is stapled to the beam B by means of two parallel lines of staples. The panel C preferably has standard dimensions, for example 2500 x 1196 mm or 2800 x 1250 mm. The panel C is then cut (step 3) at regular intervals parallel to the longitudinal members so that a cut line passes between the longitudinal members A of each pair of longitudinal members A and a cut line separates each beam B into two identical longitudinal members. Referring more particularly to Figures 2 and 3, the wall element is arranged vertically to form a wall. The beams 4 are vertical and the cross members 5 are horizontal. The bracing panel 3 is turned outward or inward. Preferably, the beams 4 are spaced apart by a distance of between 400 and 600 mm, for example. The wall elements 1, without the closure panel of the box 11, are arranged next to each other. Preferably, the bracing panel 3 of each wall member 1 has a longitudinal edge protruding from the support beam 6 to which it is attached and a longitudinal edge recessed from the support beam 6 to which it is attached. Thus, when two wall elements 1 are contiguous, the projecting edge of the bracing panel 3 of one of the wall elements 1 can be fixed on the part of the supporting spar 6 left uncovered by the longitudinal edge set back from the wall panel. bracing 3 of the other wall element 1. A thermally insulating material 9 is disposed in the cavities delimited by the supporting structure 2 and the bracing panels 3 and the closure panels of the box 11 are fixed on the additional longitudinal members 7. The bracing panel 6 has a thickness of 9 to 18 mm and the closing panel of the box 11 has a thickness of 9 to 60 mm. The panels 6 and 11 may have a grooved edge and a fluted edge to facilitate placement of the wall elements 1 side-by-side. The wall element can also be used for the realization of a partition. With reference to FIG. 4, the wall element 1 is used as a floor. The carrier spar 6 is then sized as a conventional joist and the spacing of the beams 4 is calculated in the same way as for conventional joists. The carrier spar 6 has projecting ends of the additional spar 7 to bear on bearing walls, beams or crows. The bracing panel 3 will form the upper surface of the floor thus formed. Spacers 10 may be mounted if necessary between the carrier spar 6 and the additional spar 7 to stiffen the beam 4 in bending.

L'élément de paroi 1 a une épaisseur comprise par exemple entre 200 et 500 mm. Le panneau de contreventement 6 a une épaisseur de 22 mm et le panneau de fermeture du caisson 11 a une épaisseur de 16 à 22 mm. The wall element 1 has a thickness of, for example, between 200 and 500 mm. The bracing panel 6 has a thickness of 22 mm and the closing panel of the box 11 has a thickness of 16 to 22 mm.

Les panneaux de contreventement 6 sont rainurés- 7 bouvetés. En référence à la figure 5, l'élément de paroi 1 est utilisé en partie de toiture. L'élément de paroi 1 a des extrémités inférieure et supérieure qui sont biseautées pour prendre appui respectivement sur un mur porteur ou une panne sablière et sur une autre partie de toiture ou une panne faitière. Le panneau de contreventement 3 est orienté vers l'extérieur. The bracing panels 6 are grooved-bent. With reference to FIG. 5, the wall element 1 is used partly in the roof. The wall element 1 has lower and upper ends which are bevelled to bear respectively on a bearing wall or a sandbox failure and on another part of the roof or a failure. The bracing panel 3 is facing outwards.

Des entretoises 10 peuvent être montées en cas de besoin entre le longeron porteur 6 et le longeron additionnel 7 pour rigidifier la poutre 4 en flexion. L'élément de paroi 1 a une épaisseur comprise par exemple entre 200 et 500 mm. Spacers 10 may be mounted if necessary between the carrier spar 6 and the additional spar 7 to stiffen the beam 4 in bending. The wall element 1 has a thickness of, for example, between 200 and 500 mm.

Le panneau de contreventement 6 a une épaisseur de 9 à 22 mm et le panneau de fermeture du caisson 11 a une épaisseur de 9 à 60 mm. Bien entendu, l'invention n'est pas limitée aux modes de réalisation décrits mais englobe toute variante entrant dans le champ de l'invention telle que définie par les revendications. L'agrafage peut être remplacé par tout autre mode de fixation adapté comme le clouage ou le collage. Les panneaux de bois à lamelles minces orientées dits OSB peuvent être remplacés par des panneaux bois-ciment (comme ceux de marque DURIPANEL produit par la société ETERNIT), des panneaux en fibres de bois et résine (comme ceux de marque AGEPAN DWD produits par la société ISOROY) ou, pour les panneaux de parement, des panneaux mixtes gypse et cellulose (comme ceux produits sous la marque FERMACELL par la société XELLA). Les cavités peuvent être laissées vides ou contenir un matériau d'isolation acoustique ou autre. Par panneau de fermeture, on entend tout élément 35 susceptible de fermer les cavités, que cet élément soit The bracing panel 6 has a thickness of 9 to 22 mm and the closing panel of the box 11 has a thickness of 9 to 60 mm.
