Abstract

Composite building panels are constructed as hollow structures of timber, pretreated to confer fire resistance, filled with expanded polyurethane resin either as a prefabricated panel or by resin injection in situ. Combines fire resistance with good thermal and acoustic insulation properties. Lighter than doors with metal panels or frames, and free from thermally conductive bridges at the frame joints. The edges of the panel are deep enough to form effective seals against smoke or flame penetration past a suitable supporting frame. Opt. the panels incorporate local stiffening battens, also of timber. The outermost components of the panels are connected using stepped lap joints.

Description

"Panneaux M.S."
La présente invention concerne des éléments d'ossature et de remplissage du type panneau-caisson permettant la construction de bâtiments parfaitement isolés."MS panels"
The present invention relates to framework and filling elements of the box-panel type allowing the construction of perfectly insulated buildings.

Les panneaux connus de ce genre sont tous de dimensions déterminées. The known panels of this kind are all of determined dimensions.

Les uns sont monoblocs, compacts ou alvéolés, constitués de particules bois, à liant urée-formol ou urée-mélamine. Leur emploi est limité à la confection de cloisons intérieures ayant d'assez faibles qualités isolantes tant phoniques que calorifiques.Some are monobloc, compact or honeycombed, made of wood particles, with a urea-formaldehyde or urea-melamine bond. Their use is limited to the manufacture of interior partitions having rather weak insulating qualities both phonic and calorific.

On connait aussi les panneaux-caissons constitués de deux parois en particules bois séparées par un remplissage en laine minérale ou en polystirène expansé : ces isolants ne donnant aucune garantie d'efficacité durable; en outre, le polystirène présente des dangers dans le cas d'incendie. We also know the box panels made up of two wooden particle walls separated by a filling of mineral wool or expanded polystirene: these insulators give no guarantee of lasting effectiveness; in addition, polystirene poses dangers in the event of fire.

On trouve sur le marché des panneaux-caissons en tôle d'acier (ou d'aluminium) nervurées avec interposition de mousse de polyuréthane. Leur emploi, limité aux bardages industriels, exige une ossature de soutien. Leur largeur étant assez étroite, les joints sont rapprochés et provoquent des ponts thermiques. There are ribbed steel sheet (or aluminum) box panels on the market with interposition of polyurethane foam. Their use, limited to industrial cladding, requires a support frame. Their width being quite narrow, the joints are close together and cause thermal bridges.

Le procédé de la présente invention permet d'éviter ces inconvénients. The process of the present invention makes it possible to avoid these drawbacks.

Il consiste à fabriquer et à poser des panneaux-caissons aux dimensions imposées par la construction de l'ensemble et constitués de deux parements en bois igni fugés, avec interposition d'une âme en polyuréthane.It consists of manufacturing and installing box panels to the dimensions imposed by the construction of the assembly and made up of two fire-retardant wood siding, with the interposition of a polyurethane core.

Le dessin en fait comprendre la constitution. The drawing makes it understand the constitution.

Les parois de bois peuvent être soit, comme le dessin le représente, en planches assemblées (1) et raidies par tasseaux (2), soit par des lamelles collées. Leur surface n'est pas limitée aux dimensions du commerce et peut être déterminée suivant la demande. Leur épaisseur, ainsi que le mode de raidissement sont variables selon les sujétions imposées par les besoins auxquels ils sont destinés dans la construction : résistance mécanique, conductivité thermique et phonique. The wooden walls can be either, as the drawing shows, in assembled planks (1) and stiffened by battens (2), or by glued strips. Their surface is not limited to the dimensions of the trade and can be determined according to demand. Their thickness, as well as the stiffening mode are variable according to the constraints imposed by the needs for which they are intended in construction: mechanical resistance, thermal and sound conductivity.

La mousse de polyuréthane est injectée sous pression entre les deux parements (3). Cette opération peut être faite pour un seul panneau en atelier, ou in situ pour un ensemble de panneaux constituant une paroi de bâtiment par exemple. On contrôle la diffusion uniforme de la mousse qui, se cristallisant en surface, adhère au bois et procure une parfaite étanchéité. The polyurethane foam is injected under pressure between the two facings (3). This operation can be done for a single panel in the workshop, or in situ for a set of panels constituting a building wall for example. We control the uniform diffusion of the foam which, crystallizing on the surface, adheres to the wood and provides a perfect seal.

D'autre part, par la qualité ininflammable de ce matériau (classé MX par le P.V. du C.S.T.B. n079.15376), cette âme de polyuréthane assure une garantie évidente aux risques d'incendie.  On the other hand, by the non-flammable quality of this material (classified MX by the P.V. of the C.S.T.B. n079.15376), this polyurethane core provides an obvious guarantee against fire risks.

Le principe de cette invention peut etre utilisé dans la construction de maisons à usage principalement d'habitation, mais aussi, en partie, de bâtiments industriels et commerciaux. Car il offre à la fois les avantages d'un isolant phonique, d'un isolant thermique sans discontinuité aux joints, présentant les garanties demandées par la législation et les compagnies d'assurances, en matière de sécurité. Il peut servir d'ossature principale, mais également de bardage, plancher, cloison, support de couverture. Sa mise en oeuvre, en usine comme à la pose, est d'un emploi facile et peu coûteux au regard des exigences qui lui sont demandées.  The principle of this invention can be used in the construction of houses mainly for residential use, but also, in part, industrial and commercial buildings. Because it offers both the advantages of a sound insulator, of a thermal insulation with no discontinuity in the joints, presenting the guarantees requested by the legislation and the insurance companies, as regards safety. It can be used as main frame, but also as cladding, floor, partition, roof support. Its implementation, both in the factory and at installation, is easy to use and inexpensive with regard to the requirements that are required of it.
