Abstract

The self-supporting wooden structure is in the shape of complete roof or wall panels. The panels comprise rafters (1) and purlins (2) forming a beam trellis. The upper and lower parts of the beam are connected by the purlins in order to take up shearing of the beam. The girders of the beam are composed of draw plates fixed perpendicularly to the rafters.

Description

1. -- La présente invention est du domaine de la construction et concerne plus particulièrement les toitures, dalles et murs en ossature bois .1. - The present invention is in the field of construction and concerns more particularly wooden frame roofs, slabs and walls.

L'assemblage de toitures et dalles en bois se fait principalement sur le chantier. Dans certains cas, pour autant que la disposition des pièces s'y prêtent, des panneaux complets de toiture sont réalisés dans le sens des chevrons. Cette façon de procéder pose des problèmes de raccords divers tels que, étanchéité de la barrière vapeur et de la sous couverture. De plus, ce sytème nécessite la pose, au préalable, de pannes et de sablières.The assembly of wooden roofs and tiles is mainly done on the construction site. In some cases, provided that the layout of the documents lend, complete roof panels are made in the direction of rafters. This procedure poses connection problems various such as, sealing of the vapor barrier and the undercover. In addition, this system requires the installation, beforehand, of purlins and sand pits.

L'invention a pour but de permettre la réalisation de toitures préfabriquées et modulaires comprenant le lattage, le contrelattage, la sous couverture, la structure-planches autoportante, l'isolation, la barrière vapeur et le revêtement intérieur ainsi que la ferblanterie.The invention aims to allow the production of prefabricated roofs and modular including battening, counter-battling, undercovering, the self-supporting plank structure, insulation, vapor barrier and interior lining as well as tinsmithing.

La structure bois autoportante se présente sous forme de panneaux pouvant prendre appui sur chacun de ses côtés. Ses applications sont les toitures, dalles et murs. Ces panneaux sont caractérisés par des chevrons(solives) et de pannes composées(I beam) qui se situent dans la même épaisseur que les chevrons, cet enchevêtrement forme un treillis de poutres. Les pannes composées en « I » sont caractérisées par leur âme formée par les étraisillons. The self-supporting wooden structure is in the form of panels that can be supported on each of its sides. Its applications are roofs, slabs and walls. These panels are characterized by rafters (joists) and composite purlins (I beam) which are located in the same thickness as the rafters, this entanglement forms a lattice of beams. The I-shaped purlins are characterized by their core formed by the struts.

Les parties supérieures et inférieures (longerons) de cette poutre composée sont caractérisées par leur liaison aux étraisillons afin de reprendre le cisaillement de la poutre .
Les longerons de cette poutre composée, qui travaillent en traction et compression, sont composés par des filières, fixées perpendiculairement aux chevrons et reliées aux étraisillons. Ces longerons peuvent être en bois massif, composées par des panneaux partiellement ou sur toute la surface, des feuillards métalliques ou autre.The upper and lower parts (spars) of this composite beam are characterized by their connection to the braces in order to resume the shearing of the beam.
The beams of this composite beam, which work in tension and compression, are composed by longlines, fixed perpendicular to the rafters and connected to the braces. These beams can be solid wood, composed by panels partially or over the entire surface, metal strips or other.

La structure utilise 50% moins de bois qu'une réalisation traditionnelle.The structure uses 50% less wood than a traditional production.

La fabrication en halle optimalise la gestion et la rationnalisation de la production.Hall manufacturing optimizes management and rationalization of production.

La diminution du travail sur le chantier favorise l'extension du rayon d'action de l'entreprise.The reduction of work on the site favors the extension of the radius action.

La structure auto portante permet de faire des raccords de toiture horizontauxThe self-supporting structure makes it possible to make roof connections horizontal

L'invention est décrite ci-après à l'aide d'un exemple et de références aux dessin ci-joint, pour le cas de toitures nécessitant une ventillation entre la couverture et le lattage, dans lesquels:The invention is described below using an example and references to attached drawing, in the case of roofs requiring ventilation between the cover and battening, in which:

La figure 1 qui est une partie de toiture en perspective, nous montre une structure bois auto portante ventillée, dont l'étraisillon 2 sur sa partie supérieure n'est pas relié au longeron, le longeron supérieur étant remplacé, dans cet exemple, par le lattage à tuiles 5. le contrelattage 4, de chaque côté du chevron 1 ,permet de renforcer la surface du noeud d'assemblage (chevron 1 / lattage 5).Figure 1 which is a perspective part of the roof, shows us a self-supporting ventilated wooden structure, the strut 2 on its upper part is not connected to the spar, the upper spar being replaced, in this example, by the tile batten 5 . the counterattack 4 , on each side of the rafter 1 , makes it possible to reinforce the surface of the assembly knot (rafter 1 / batten 5 ).

La particularité de cette structure est que le lattage et le contrelattage font partie intégrante du système statique, ils répondent à des contraintes de compression et de flambage. Les longerons 6 sont dans l'épaisseur de la toiture et peuvent être répartis selon la position des appuis souhaités. La fabrication normalisée des éléments facilite l'utilisation de plaques d'isolation standard.The particularity of this structure is that battening and counter-battening are an integral part of the static system, they respond to compression and buckling constraints. The longitudinal members 6 are in the thickness of the roof and can be distributed according to the position of the desired supports. The standardized manufacturing of the elements facilitates the use of standard insulation plates.
