Abstract

The plank is formed of a core (2) made of insulating material to which are glued two longitudinal timber pieces (1) forming the lateral faces of the plank. At the ends, the lateral pieces (1) protrude beyond the insulating core (2), thus creating a free space (3) which is occupied by a timber block (4) whose grain is crossed with respect to that of the longitudinal pieces (1). Thus the heads of the plank, that is to say the parts of the latter which protrude when the planks are fitted into each other, in a crossed manner, are made of solid timber and are connected to the remainder of the plank by the pieces (1) which are integral with the latter.

Description

Madrier composite pour la construction de chalets.Composite plank for the construction of chalets.

La présente invention a pour objet un madrier compo; site pour la construction de chalets, constitué par une âme en matière isolante interposée et collée entre deux pièces longitudinales de bois formant les faces latérales du madrier. The present invention relates to a composite log; site for the construction of chalets, constituted by a core of insulating material interposed and glued between two longitudinal pieces of wood forming the lateral faces of the plank.

De tels madriers composites sont connus en soi. Ils ont l'avantage de présenter de hautes qualités isolantes tant du point de vue thermique que phonique. Such composite planks are known per se. They have the advantage of having high insulating qualities both from a thermal and a sound point of view.

La construction de chalets au moyen de madriers s'effectue en engageant les madriers, préalablement encochés à leurs extrémités, les uns dans les autres. L'inconvénient: des madriers composites réside dans le fait que les têtes des madriers, c'est-à-dire leurs parties terminales situées au-delà de leurs points de croisement, lorsqu'ils sont assemblés, sont elles-mêmes composites, ce qui est inesthétique. I1 est de surcroît défavorable que la matière isolante soit directement exposée aux intempéries. The construction of chalets using planks is carried out by engaging the planks, previously notched at their ends, one inside the other. The disadvantage: composite planks resides in the fact that the planks heads, that is to say their end parts located beyond their crossing points, when they are assembled, are themselves composite, this which is unsightly. It is moreover unfavorable for the insulating material to be directly exposed to the weather.

On a tenté de résoudre ce problème en munissant de tels madriers composites de têtes en bois plein rapportées sur le corps principal du madrier. Une telle solution présente toutefois l'inconvénient que les têtes ne sont pas fixées de façon sûre puisqu'elles ne font pas corps avec le madrier, de sorte que la solidité de l'assemblage même des madriers est ainsi compromise. An attempt has been made to resolve this problem by providing such composite planks with solid wooden heads attached to the main plank body. However, such a solution has the disadvantage that the heads are not securely fixed since they do not form a body with the plank, so that the solidity of the very assembly of the planks is thus compromised.

Le but de la présente invention est de fournir une solution à ce problème. Ce but est atteint grâce aux moyens revendiqués. The object of the present invention is to provide a solution to this problem. This goal is achieved by the means claimed.

Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention. The drawing represents, by way of example, an embodiment of the subject of the invention.

La fig. 1 est une vue en perspective d'une partie d'un madrier composite pour la construction de chalets. Fig. 1 is a perspective view of part of a composite plank for the construction of chalets.

La fig. 2 en est une coupe longitudinale suivant son plan médian.  Fig. 2 is a longitudinal section along its median plane.

La fig-. 3 en est une vue en bout prise de la droite de la fig. 2, et
La fig. 4 est une vue en perspective d'une partie du madrier en cours de fabrication.The fig-. 3 is an end view taken from the right of FIG. 2, and
Fig. 4 is a perspective view of part of the log during manufacture.

Le madrier représenté comprend deux pièces longitudinales de bois 1, s'étendant sur toute sa longueur, formées chacune de deux planches collées la et lb, et qui constituent les faces latérales du madrier. Une âme 2 de matière plastique isolante, formée par exemple de mousse de polyuré- thane expansée à pores fermés, est interposée entre les deux pièces latérales 1 auxquelles elle est collée. Comme le montrent les figs. 2 et 4, cette âme 2 de matière isolante ne s'étend pas jusqu'aux extrémités des pièces latérales 1, ces dernières la dépassant légèrement. L'espace libre ainsi ménagé entre les extrémi-tés des deux pièces 1, visible à la fig. 4 où il est désigné par 3, est occupé par un plot de bois 4 formé de trois planches 4a, 4b et 4c, collées les unes aux autres, et qui est collé lui-même aux pièces latérales 1. The plank shown comprises two longitudinal pieces of wood 1, extending over its entire length, each formed from two glued boards 1a and 1b, and which constitute the lateral faces of the plank. A core 2 of insulating plastic, formed for example of expanded polyurethane foam with closed pores, is interposed between the two side pieces 1 to which it is bonded. As shown in figs. 2 and 4, this core 2 of insulating material does not extend to the ends of the side pieces 1, the latter slightly exceeding it. The free space thus provided between the extremi-ties of the two parts 1, visible in FIG. 4 where it is designated by 3, is occupied by a wooden stud 4 formed by three boards 4a, 4b and 4c, glued to each other, and which is itself glued to the side pieces 1.

La hauteur des pièces latérales 1 est supérieure à celle de l'âme 2 de sorte qu'il y a encore place, au-dessus et au-dessous de celle-ci, pour deux pièces longitudinales de bois 5, collées à l'âme 2 et aux pièces 1, qui forment les faces supérieure et inférieure du madrier. Ces pièces 5 ont la longueur de l'âme 2, les plots 4 d'extrémité du madrier ayant la hauteur des pièces 1. The height of the side pieces 1 is greater than that of the core 2 so that there is still room, above and below the latter, for two longitudinal pieces of wood 5, glued to the core 2 and parts 1, which form the upper and lower faces of the plank. These pieces 5 have the length of the core 2, the studs 4 at the end of the plank having the height of the pieces 1.

Comme le montrent les traits mixtes de la fig. 2, qui représentent les deux encoches 6 qui sont ménagées ultérieurement au voisinage des extrémités du madrier pour permettre l'assemblage croisé de plusieurs d'entre eux, ces encoches sont pratiquées au droit des -extrémités de l'âme 2 du madrier et sont adjacentes aux plots 4. I1 est à remarquer que, le plus généralement, les encoches 6 seront réalisées par le charpentier sur le chantier de construction et non pas par le fabricant du madrier. As shown by the dashed lines in fig. 2, which represent the two notches 6 which are formed later in the vicinity of the ends of the plank to allow the cross assembly of several of them, these notches are made at the level of the ends of the core 2 of the plank and are adjacent studs 4. It should be noted that, more generally, the notches 6 will be made by the carpenter on the construction site and not by the manufacturer of the plank.

I1 résulte de cet agencement que les têtes des madriers c'est-à-dire la partie située au-delà des encoches., sont parfaitement reliées au corps de celui-ci puisque les pièces latérales 1 s'étendent de bout en bout du madrier, assurant la liaison avec lesdites têtes. Ces dernières sont en bois plein, mais l'isolation s'étend jusqu'au droit des croisements des madriers, de sorte qu'il n"y a pas de ponts thermiques ou phoniques auxdits croisements. It results from this arrangement that the heads of the planks, that is to say the part located beyond the notches, are perfectly connected to the body thereof since the side pieces 1 extend from end to end of the plank , ensuring the connection with said heads. The latter are made of solid wood, but the insulation extends to the right of the crosses of the planks, so that there are no thermal or phonic bridges at the said crossings.

Il est à remarquer que, le plus généralement, ce seront les deux extrémités du madrier qui seront munies de têtes en bois plein. On pourra cependant prévoir le cas où seule une des extrémités du madrier comportera une telle tête. Ce sera, par exemple, le cas lorsque le madrier ne doit pas s'étendre sur toute la longueur de la façade du chalet, mais seulement sur une partie de cèlle-ci, comme c'est le cas lorsque le madrier est situé au droit d'une porte ou d'une fenêtre, notamment. It should be noted that, more generally, it will be the two ends of the plank which will be provided with solid wooden heads. We can however foresee the case where only one of the ends of the plank will include such a head. This will be, for example, the case when the log should not extend over the entire length of the facade of the chalet, but only over part of it, as is the case when the log is located at right a door or a window, in particular.
