Abstract
Pièce structurelle en bois au treillis orthogonal entrant dans la composition de murs ou planchers d'une construction. L'invention concerne un assemblage rapide et efficace d'éléments en bois formant une pièce légère, résistante et pouvant autoriser le passage des réseaux. Elle est constituée de deux membrures (2) solidarisées par des lattes (4) grâce à des connecteurs métalliques (3) caractérisés par des plaques hérissées de pointes. Ces connecteurs bloquent la rotation des éléments occasionnée par la charge. Le chant extérieur des membrures peut être raboté pour recevoir un matériau de parement ou un revêtement. Le vide occasionné par la constitution de la pièce au treillis orthogonal autorise le passage de tous les réseaux installés dans une construction, les éléments la composant servent même de support lors de la pose. Cette invention est destinée à rentrer dans la composition d'éléments structurels en bois tels que les murs et planchers d'une construction.Structural wooden piece with orthogonal lattice used in the composition of walls or floors of a building. The invention relates to a fast and efficient assembly of wooden elements forming a light, resistant and able to allow the passage of networks. It consists of two ribs (2) secured by slats (4) thanks to metal connectors (3) characterized by spiky plates. These connectors block the rotation of the elements caused by the load. The outer edge of the chords can be planed to receive facing material or cladding. The vacuum caused by the constitution of the orthogonal lattice part allows the passage of all the networks installed in a construction, the components of the component even serve as support during installation. This invention is intended to enter the composition of structural elements of wood such as the walls and floors of a building.
Description
-1- L'invention sujette de ce dépôt de brevet concerne la composition d'une pièce structurelle en bois, à treillis orthogonal assemblé par connecteurs métalliques. Les pièces à treillis employées habituellement sont triangulées. Les lattes constituant l'âme sont collées, encastrées de biais dans les membrures inférieures et supérieures de la pièce. Ce procédé implique des mesures d'angles, des coupes biaises, un usinage des membrures pour l'intégration des lattes et des moyens employés pour le collage, temps de prise dans un milieu au taux d'humidité régulé, contrôle de l'humidité du bois. Le principe de fabrication de la pièce au treillis orthogonal facilite l'assemblage des éléments, entrainant un gain de temps et limitant les défauts de conception. En effet les éléments aboutés sont assemblés par connecteurs métalliques, type plaques à griffes, sur table d'assemblage ou les lattes constituant l'âme sont positionnées avant d'être solidarisées par presse avec les membrures. En plus de cette facilité de fabrication, les vides entre lattes permettent le passage des réseaux (électricité, fluides, air conditionné) intégrant donc à la structure le faux plafond prévu normalement à cet effet. Cette disposition diminue la hauteur de la construction et donc favorise les économies de matériaux. Les dessins joints présentent l'invention : La figure 1 est une coupe transversale laissant apparaître les pièces formant un plancher bois d'habitat avec réseaux intégrés. La figure 2 est une vue en élévation d'une pièce, en gros plan, une travée de lattes assure le 20 transfert de charge d'une membrure à l'autre. Ces dessins illustrent la composition et un emploi de la pièce à treillis orthogonal (1). Elle est composée de deux membrures (2), à section carrée ou rectangulaire, la rectangulaire étant la plus adaptée à la reprise des efforts. Ces deux éléments sont en bois, d'une classe structurelle élevée, éliminant un maximum les défauts du matériau pour reprendre 25 efficacement les charges. Le chant extérieur des membrures (2) peut être raboté pour former un support plan de matériau (6). Des lattes verticales (4), de préférence rectangulaires, sont positionnées à intervalles réguliers entre ces membrures (2) pour les lier l'une à l'autre et ainsi former une pièce solidaire (1). Elles transfèrent les forces d'une membrure (2) à l'autre. Ces éléments 30 verticaux (4) sont assemblés par des connecteurs métalliques (3) employés pour les assemblages structurelles reprenant des efforts élevés. -2- Ils s'agit d'une plaque de métal hérissée de pointes (3) pénétrant dans le bois par pressage. Ces plaques (3) sont fixées à chaque jonction de membrures (2) et de lattes (4), soit 2 plaques (3) par lattes (4). L'emploi de l'invention est adapté à former la structure porteuse d'un plancher (1) ou 5 d'un mur, permettant l'intégration des réseaux (5) de la construction et aussi la fixation de matériaux (6), sur ses chants supérieurs comme inférieurs. Cette invention est destinée à la fabrication répétitive de la pièce, permise par sa légèreté, un assemblage rapide et simple d'éléments peu usinés. Elle est réalisable par de nombreuses machines outils utilisées dans le secteur du bois construction.The subject invention of this patent application relates to the composition of a wooden structural part, orthogonal mesh assembled by metal connectors. The lattice workpieces usually used are triangulated. The slats constituting the core are glued, recessed at an angle in the lower and upper chords of the piece. This process involves measurements of angles, slanting cuts, machining of the frames for the integration of slats and the means used for bonding, setting time in a medium at controlled humidity, control of the humidity of the slats. wood. The manufacturing principle of the orthogonal lattice part facilitates the assembly of elements, saving time and limiting design defects. Indeed, the abutting elements are assembled by metal connectors, type claw plates, on assembly table or slats constituting the core are positioned before being secured by press with the frames. In addition to this ease of manufacture, the gaps between slats allow the passage of networks (electricity, fluids, air conditioning) thus integrating the structure the false ceiling normally provided for this purpose. This arrangement decreases the height of the building and therefore promotes material savings. The accompanying drawings show the invention: FIG. 1 is a transverse section showing the parts forming a wooden floor of habitat with integrated networks. Figure 2 is an elevational view of a workpiece, in close-up view, a lath span provides load transfer from one chord to the other. These drawings illustrate the composition and use of the orthogonal lattice piece (1). It is composed of two chords (2), with square or rectangular section, the rectangular being the most adapted to the recovery of efforts. These two elements are made of wood, of high structural class, eliminating a maximum of the defects of the material to take up the loads effectively. The outer edge of the chords (2) can be planed to form a flat material support (6). Vertical slats (4), preferably rectangular, are positioned at regular intervals between these ribs (2) to bind one to the other and thus form an integral part (1). They transfer the forces from one chord (2) to the other. These vertical elements (4) are assembled by metal connectors (3) used for structural assemblies with high forces. -2- This is a metal plate spiked with points (3) penetrating into the wood by pressing. These plates (3) are attached to each junction of frames (2) and slats (4), or 2 plates (3) per slats (4). The use of the invention is adapted to form the supporting structure of a floor (1) or a wall, allowing the integration of networks (5) of the construction and also the fixing of materials (6), on his upper and lower songs. This invention is intended for the repetitive manufacture of the piece, permitted by its lightness, a quick and simple assembly of low-machined elements. It is achievable by many machine tools used in the timber industry.
