Abstract

The center layer of the composite laminated plate is made of copper, aluminum or non-rusting high-quality steel. Decorative veneers made of high quality wood may be glued to this metal layer to give the appearance of a wooden panel. A single layer of metal (5) is used with one layer of wood (3,4) on either side. Alternatively there may be two layers of wood on either side of the central metal layer.

Description

<U>STRUCTURE DE CONTREPLAQUE STRATIFIE</U> ARRIERE-PLAN <U>DE L'INVENTION</U> La figure 1 montre une structure de contreplaqué classique comprenant une couche extérieure 11 une couche inférieure 12, les deux couches 11, 12 ayant une orientation des fibres de bois dans une direction similaire. Une couche médiane 13 est placée entre les deux couches 11, 12 et a une orientation des fibres de bois verticale. Les couches 11, 12, 13 sont collées ensemble pour former un produit stratifié synthétique. Comme la couche médiane 13 est entourée par les deux couches 11, 12, ce peut être un panneau d'un matériau de qualité inférieure. En outre, l'orientation des fibres de bois est différente de celle des deux couches 11, 12 de manière à réduire la déformation de la structure de contreplaqué stratifié. Cependant, une section transversale en dents de scie va se former si le produit stratifié est coupé, et il ne va pas pouvoir être fraisé pour améliorer la section transversale en dents de scie. Ainsi, cette structure de contreplaqué stratifié est uniquement employée dans la fabrication de produit faible coût. BACKGROUND OF THE INVENTION FIG. 1 shows a conventional plywood structure comprising an outer layer 11 a lower layer 12, the two layers 11, 12 having a wood fiber orientation in a similar direction. A middle layer 13 is placed between the two layers 11, 12 and has a vertical wood fiber orientation. The layers 11, 12, 13 are glued together to form a synthetic laminate product. Since the middle layer 13 is surrounded by the two layers 11, 12, it may be a panel of a lower quality material. In addition, the orientation of the wood fibers is different from that of the two layers 11, 12 so as to reduce the deformation of the laminated plywood structure. However, a sawtooth cross section will form if the laminate product is cut, and it will not be able to be milled to improve the sawtooth cross section. Thus, this laminated plywood structure is only used in the manufacture of low cost product.

La demande de brevet ROC No. 87204102, intitulée "Improved structure of plywood", déposée par le même demandeur décrit une structure de contreplaqué 2, comme représenté sur la figure 2. La structure de contreplaqué 2 comprend une pluralité de couches extérieures 21, 22, et une couche 'diane 23. Les orientations des fibres de bois des couches individuelles sont similaires mais l'orientation des fibres de bois de la section transversale verticale 231 et celle de la section transversale horizontale 232 de la couche médiane 23 ne sont pas reliées entre elles. En raison de la discontinuité des orientations des fibres de bois, la tension des fibres de bois est supprimée et la déformation de la structure de contreplaqué peut être évitée. En raison de la direction similaire d'orientation des fibres de bois des couches extérieures 21, 22 et de la couche médiane 23, la surface de section est une surface plate qui peut être fraisée pour un procédé de fabrication ultérieur. ROC patent application No. 87204102, entitled "Improved structure of plywood", filed by the same applicant describes a plywood structure 2, as shown in FIG. 2. The plywood structure 2 comprises a plurality of outer layers 21, 22 , and a diane layer 23. The orientations of the wood fibers of the individual layers are similar but the orientation of the wood fibers of the vertical cross-section 231 and that of the horizontal cross-section 232 of the middle layer 23 are not related. between them. Due to the discontinuity of the orientations of the wood fibers, the tension of the wood fibers is eliminated and the deformation of the plywood structure can be avoided. Due to the similar direction of orientation of the wood fibers of the outer layers 21, 22 and the middle layer 23, the sectional area is a flat surface that can be milled for a subsequent manufacturing process.

Cependant, quand le bois est contact avec de l'humidité ou est à une température élevée, en raison de la propriété physique du matériau, les fibres du bois de la couche extérieure vont gonfler et une force de poussée se forme en une autre partie de la structure de contreplaqué de telle sorte que tout le contreplaqué ou une partie du contreplaqué peut être déformé. Une structure ayant subi une telle déformation ne peut être ramenée à sa forme originale même quand la température ou l'humidité est revenue à la normale. However, when the wood is in contact with moisture or is at a high temperature, due to the physical property of the material, the wood fibers of the outer layer will swell and a pushing force will form in another part of the wood. the plywood structure so that all the plywood or part of the plywood can be deformed. A structure that has undergone such deformation can not be returned to its original form even when the temperature or humidity has returned to normal.

DESCRIPTION DETAILLEE <U>DE LA</U> PRESENTE <U>INVENTION</U> La présente invention réalise une nouvelle structure de contreplaqué qui a une application plus large que celle du bois naturel. La présente invention réduit également la consommation de bois naturel associée et évite des détériorations excessives de l'environnement biologique. DETAILED DESCRIPTION OF THE PRESENT <U> INVENTION </ U> The present invention provides a new plywood structure that has a wider application than natural wood. The present invention also reduces the associated natural wood consumption and avoids excessive deterioration of the biological environment.

En se référant aux figures 3 et 4, la présente structure comprend deux couches extérieures 3, 4 avec couche médiane 5 collée entre elles. La présente structure peut également comprendre une pluralité de couches extérieures 3, 4 avec une couche médiane 5 collée entre elles. Selon la présente invention, les couches extérieures 3, 4 sont faites de bois, comme d'une planche, d'un simple panneau, de contreplaqué stratifié ou d'un panneau de fibres et les orientations des fibres de bois des couches ont une direction similaire. La couche médiane 5 est une plaque métallique, comme une plaque d'aluminium, une plaque de cuivre, une plaque d'acier inoxydable, etc., qui est un matériau métallique résistant à la rouille et a une épaisseur d'environ 0,05 mm, de préférence. Une colle résistant à l'eau est employée pour coller la couche médiane 5 entre les deux couches extérieures 3, 4 afin de former un bloc de contreplaqué. La structure de contreplaqué stratifié selon la présente invention, en raison de la résistance, de l'élasticité de la dureté de la plaque métallique comme couche médiane, peut être utilisée comme mur de support ou mur isolant. De plus, comme la conductibilité de chaleur et la dissipation de chaleur sont meilleures que celles du bois, on peut l'utiliser comme panneau conducteur de la chaleur. Referring to Figures 3 and 4, the present structure comprises two outer layers 3, 4 with medial layer 5 bonded together. The present structure may also comprise a plurality of outer layers 3, 4 with a medial layer 5 bonded together. According to the present invention, the outer layers 3, 4 are made of wood, such as a board, a single panel, laminated plywood or a fiber board and the orientations of the wood fibers of the layers have a direction similar. The middle layer 5 is a metal plate, such as an aluminum plate, a copper plate, a stainless steel plate, etc., which is a rust-resistant metal material and has a thickness of about 0.05 mm, preferably. A water-resistant adhesive is used to bond the middle layer 5 between the two outer layers 3, 4 to form a plywood block. The laminated plywood structure according to the present invention, because of the strength, resilience of the hardness of the metal plate as the middle layer, can be used as a support wall or insulating wall. In addition, since heat conductivity and heat dissipation are better than those of wood, it can be used as a heat conducting panel.
