Abstract

A rigid composite roofing matl. comprises a layer of rot proof non-woven matting coated on the underside with a layer of waterproof mtl. and on the upper surface with a layer of rigid resin dressed with mineral aggregates. Suitable for covering horizontal, sloping or vertical surfaces, opt. are moulded to resemble conventional roofing materials, e.g. Roman-style tiles. Pref. the matting is made from polyester filaments. The waterproof layer may be a coating of bitumen or a layer of PVC sheet, opt. used as an interlayer bonding together two layers of matting. The composite may incorporate continuous cords or tapes pre-extended to maintain the sheet in a stressed condition. Opt. the underside of the composite is lined with a (thick) layer of thermal insulation, specifically or phenolic foam or cellular plaster; the layer of insulation may incorporate ancillary supporting rafters. Pref. the composite board can be shaped by pressing at less than 100, pref. 60-80 deg.C.

Description

L'invention concerne un nouvel élément de couverture. The invention relates to a new cover element.

I1 est connu d'utiliser le bitume pour réaliser des éléments de couverture non porteurs et plats, c'est-a-dire à deux dimensions, par exemple du carton bituminé, du feutre bitumineux, des plaques de couverture. I1 is known to use bitumen to make non-load-bearing and flat covering elements, that is to say two-dimensional, for example bituminous cardboard, bituminous felt, covering plates.

La présente invention vise également à utiliser le bitume pour réaliser des éléments de couverture, mais des éléments porteurs et tridimensionnels. The present invention also aims to use bitumen to produce roofing elements, but load-bearing and three-dimensional elements.

L'élément de l'invention comprend une nappe d'un non-tissé à la sous-face de laquelle adhere une couche de bitume et à la surface de laquelle a été polymérisée une résine thermodurcissable dans laquelle sont ancrés des agrégats minéraux. The element of the invention comprises a sheet of a nonwoven fabric on the underside of which a layer of bitumen adheres and on the surface of which has been polymerized a thermosetting resin in which mineral aggregates are anchored.

L'invention s'applique à tous les types de bitume et notamment à ceux qui contiennent des agents de stabilisation et d'amélioration des qualités mécaniques. The invention applies to all types of bitumen and in particular to those which contain agents for stabilizing and improving mechanical qualities.

Le non-tissé est par exemple un non-tisse en fil imputrescible de polyester (produit $'Bidim" de la société
RHONE POULENC TEXTILE).The nonwoven is, for example, a nonwoven of rot-proof polyester yarn (product $ 'Bidim "from the company
RHONE POULENC TEXTILE).

La résine est choisie à volonté dans les résines thermodurcissables les moins couteuses. The resin is chosen as desired from the least expensive thermosetting resins.

La figure unique du dessin joint est une coupe verticale d'un élément selon l'invention. The single figure of the accompanying drawing is a vertical section of an element according to the invention.

Cet élément comprend des zones convexes 1 imitant l'aspect de tuiles creuses et des zones plates 2 entre les zones convexes. This element comprises convex zones 1 imitating the appearance of hollow tiles and flat zones 2 between the convex zones.

Le non-tissé comprend une partie de base 3a à laquelle est appliqué le bitume 4 et une partie superficielle 3b imprégnée d'une résine dans laquelle sont ancrés des agrégats minéraux 5, par exemple des particules de terre cuite. The nonwoven comprises a base part 3a to which the bitumen 4 is applied and a surface part 3b impregnated with a resin in which mineral aggregates 5 are anchored, for example earthenware particles.

Un procédé industriel ou artisanal pour fabriquer cet élément comprend l'application d'une feuille de bitume, dans des conditions assurant l'adhérence, sur une face d'une nappe d'un non-tissé ; le thermo-emboutissage du complexe obtenu pour lui conférer la forme tridimensionnelle désirée l'application sur l'autre face du non-tissé d'une résine thermodurcissable, ainsi que de ses compléments de polymérisation et des agrégats minéraux, et le durcissement de la résine pour ancrer les agrégats dans la résine. An industrial or artisanal process for manufacturing this element comprises the application of a bitumen sheet, under conditions ensuring adhesion, on one face of a sheet of a nonwoven; the thermo-stamping of the complex obtained to give it the desired three-dimensional shape the application on the other side of the nonwoven of a thermosetting resin, as well as its polymerization supplements and mineral aggregates, and the hardening of the resin to anchor the aggregates in the resin.

De préférence, la feuille de bitume est appliquée au non-tissé alors qu'elle provient directement du calendrage et qu'elle est donc encore chaude, ce qui assure son adhérence. Preferably, the bitumen sheet is applied to the nonwoven while it comes directly from the calendaring and is therefore still hot, which ensures its adhesion.

Si on le désire, on réactive la feuille refroidie-ou on utilise des agents d'adhérence.If desired, the cooled sheet is reactivated or adhesives are used.

L'invention s'applique à toutes formes et à toutes dimensions d'éléments de couverture.  The invention applies to all shapes and all dimensions of cover elements.
