Abstract

La présente invention consiste à coller sur chaque face d'un panneau de fibre de bois longue liée avec du ciment et de la colle un treillis résistant, par exemple en fibre de verre, afin de rendre structurel le nouveau panneau obtenu. Le treillis et le ciment colle déposés sur chaque face forment ainsi les deux peaux du panneau de type sandwich et contrôle la dilatation d'origine hygrométrique ou thermique de la surface globale mise en œuvre.The present invention consists in sticking on each side of a long wood fiber board bonded with cement and glue a resistant mesh, for example fiberglass, in order to make structural the new panel obtained. The mesh and cement glue deposited on each face thus form the two skins of the sandwich-type panel and controls the hygrometric or thermal origin expansion of the overall surface implemented.

PANNEAU STRUCTUREL EN FIBRE DE BOIS LONGUE LIEE AU CIMENT, REVETU SUR CHAQUE FACE D’UN TREILLIS RESISTANTSTRUCTURAL PANEL IN LONG-CEMENT WOODEN FIBER, COATED ON EVERY SIDE OF A RESISTANT TREILLIS

DOMAINE TECHNIQUETECHNICAL AREA

Le domaine concerné par la présente invention est celui des produits pour le bâtiment, plus particulièrement celui des panneaux en fibre de bois longue enrobée d’un liant à base de ciment et de colle.The field concerned by the present invention is that of products for the building, more particularly that of long wood fiber panels coated with a binder based on cement and glue.

TECHNIQUE ANTERIEUREPRIOR ART

Les panneaux de fibre de bois longue enrobée d’un liant à base de ciment et de colle sont répandus dans le bâtiment en raison principalement de leur qualité d’isolation phonique et acoustique d’une part, et de leur bonne résistance au feu d’autre part. Leur propriété d’isolation thermique reste faible par rapport à des isolants plus spécifiques comme les polystyrènes expansés ou les mousses de polyuréthane. Ces panneaux de fibre longue de bois présentent l’inconvénient d’une variation dimensionnelle relativement importante en fonction de l’hygrométrie ambiante et leurs faibles caractéristiques mécaniques ne permet pas de les utiliser comme produits structurels par exemple en dalles porteuses ou élément de façade susceptibles de participer au contreventement d’un bâtiment.Long-fiber wood panels coated with a cement-based binder and glue are widespread in the building mainly because of their sound and acoustic insulation quality on the one hand, and their good fire resistance. somewhere else. Their thermal insulation property remains low compared to more specific insulators such as expanded polystyrenes or polyurethane foams. These long wood fiber panels have the disadvantage of a relatively large dimensional variation depending on the ambient humidity and their low mechanical characteristics do not allow them to be used as structural products for example slabs carriers or facade element likely to participate in the bracing of a building.

EXPOSE DE L’INVENTION L’invention consiste à revêtir un panneau de fibre longue de bois enrobée d’un liant à base de ciment et de colle d’un treillis résistant, par exemple en fibre de verre, ledit treillis étant collé sur chaque face par un enduit également à base de ciment et de colle. Le panneau ainsi obtenu est un panneau de type « sandwich » dont chaque « peau » est capable de supporter des efforts, principalement de traction, la fibre de bois enrobée de ciment et colle supportant l’essentiel des efforts de compression et de cisaillement.DESCRIPTION OF THE INVENTION The invention consists in coating a long fiberboard coated with a binder based on cement and glue of a resistant mesh, for example fiberglass, said lattice being bonded to each face by a coating also based on cement and glue. The panel thus obtained is a sandwich-type panel of which each "skin" is able to withstand efforts, mainly traction, wood fiber coated with cement and glue supporting most of the compressive forces and shear.

Le treillis incorporé dans chaque « peau » étant constitué d’une matière à faible coefficient de dilatation par rapport aux variations d’hygrométrie ou aux variations thermiques, la variation dimensionnelle du panneau dans son plan est quasiment celle du treillis compte tenu du caractère caverneux de la fibre de bois longue enrobée de ciment, ledit caractère caverneux du matériau n’entrainant pas de forte contrainte sur le treillis résistant.Since the mesh incorporated in each "skin" is made of a material with a low coefficient of expansion relative to variations in hygrometry or thermal variations, the dimensional variation of the panel in its plane is almost that of the lattice, given the cavernous nature of the long wood fiber coated with cement, said cavernous nature of the material does not cause strong stress on the resistant mesh.

La présence du treillis sur chaque face confère au panneau obtenu une bonne stabilité de planéité propre aux panneaux de type sandwich en général.The presence of the lattice on each face gives the panel obtained good flatness stability specific to sandwich-type panels in general.

La mise en œuvre complète peut être réalisée de deux manières différentes : - soit la fabrication en usine de panneaux revêtus d’un treillis sur une seule face, le treillis de la deuxième face étant collé de façon continue, avec recouvrement des lés de treillis, sur l’ensemble des panneaux après leur mise en œuvre, - soit la fabrication en usine de panneaux revêtus d’un treillis sur chaque face, la liaison des différents panneaux mis en œuvre étant assurée par des bandes de treillis collées avec du ciment-colle, suivant une procédure connue.The complete implementation can be carried out in two different ways: either the factory manufacture of panels coated with a lattice on one side, the lattice of the second face being stuck continuously, with covering lattice strips, on all the panels after their implementation, - either the manufacture in factory of panels covered with a lattice on each face, the connection of the various panels implemented being ensured by strips of lattice glued with cement-glue following a known procedure.

Ces deux sortes de mise en œuvre sont avantageusement améliorées par le collage des panneaux entre eux sur les champs adjacents pendant la pose Ces panneaux de type sandwich peuvent être utilisés en dalles de plancher sur poutres en bois ou métalliques, en coffrage porteur sur lignes d’étais pour la mise en œuvre de dalles en béton armé ou en panneaux de façades posés sur ossature bois ou métallique, par exemple en support d’enduit de mortier.These two kinds of implementation are advantageously improved by gluing the panels together on the adjacent fields during the laying. These sandwich-type panels can be used as floor slabs on wooden or metal beams, as load-bearing formwork on steel lines. support for the installation of slabs of reinforced concrete or facade panels laid on wood or metal substructure, for example mortar plaster support.

Les différentes dalles constituant une surface horizontale ou verticale sont assemblées en joints alternés comme la grande majorité des panneaux utilisés dans le bâtiment.The various slabs constituting a horizontal or vertical surface are assembled in alternate joints as the vast majority of panels used in the building.

Dans le cas d’une utilisation en plancher, l’utilisation d’une bande souple entre les dalles de fibre de bois et les poutres porteuses permet d’améliorer l’isolation phonique aux bruits d’impact sur la dalle.In the case of floor use, the use of a flexible strip between the wood fiber slabs and the load-bearing beams makes it possible to improve the sound insulation with the impact noises on the slab.

Le plancher obtenu avec ces dalles de type sandwich peut recevoir à volonté du carrelage collé, un parquet bois ou un revêtement textile ou plastique.The floor obtained with these sandwich-type slabs can receive, at will, glued tiling, wood flooring or a textile or plastic covering.
