The invention also relates to the complex material used to carry out the said method. <IMAGE>

Description

La présente invention concerne un procédé pour l'entretien, la réparation et le renforcement des toitures sèches ; elle concerne également un produit pour la mise en oeuvre dudit procédé.The present invention relates to a method for the maintenance, repair and reinforcement of dry roofs; it also relates to a product for the implementation of said method.

On appelle toitures sèches, les toitures de bâtiment réalisées soit en "tôle ondulée" (ou équivalent) soit en profilés nervurés ou structurellement renforcés généralement réalisés en métal. La tôle ondulée ou les profilés structurellement renforcés sont déposés de façon . que les ondulations ou les renforcements structurels (ou nervurés) soient disposés selon la ligne de pente du toit.Dry roofs are called building roofs made either of "corrugated iron" (or equivalent) or of ribbed or structurally reinforced profiles generally made of metal. Corrugated sheet or structurally reinforced profiles are deposited in such a way. that the corrugations or the structural reinforcements (or ribbed) are arranged along the slope line of the roof.

On sait que ces toitures vieillissent ; on sait qu'il est possible de protéger les matériaux utilisés contre le vieillissement par des procédés connus comme par exemple les peintures. On a récemment proposé de réaliser cette protection en utilisant un complexe formé d'une feuille d'aluminium comportant des ondulations dans deux directions perpendiculaires doublée d'une couche qui adhère sur les éléments métalliques formant la toiture sèche. Le fait que la feuille d'aluminium comporte des ondulations dans deux directions perpendiculaires vient de ce que les techniciens tenaient à disposer d'un matériau faisant preuve d'une grande souplesse dans au moins deux directions. La couche adhésive est généralement constituée de bitume ou d'une composition à base de bitume.We know that these roofs age; it is known that it is possible to protect the materials used against aging by known methods such as, for example, paints. It has recently been proposed to achieve this protection by using a complex formed of an aluminum sheet having corrugations in two perpendicular directions doubled with a layer which adheres to the metallic elements forming the dry roof. The fact that the aluminum sheet has corrugations in two perpendicular directions comes from the fact that the technicians wanted to have a material showing great flexibility in at least two directions. The adhesive layer generally consists of bitumen or a composition based on bitumen.

Or, il a été trouvé et cela constitue la présente invention, qu'il pouvait être souhaitable de réaliser la réparation et éventuellement le renforcement des toitures sèches en utilisant un matériau composite constitué d'une feuille d'aluminium ondulée sur une face de laquelle on a déposé au moins une couche constituée de bitume ou d'un composé à base de bitume.However, it has been found and this constitutes the present invention, that it could be desirable to carry out the repair and possibly the reinforcement of dry roofs by using a composite material consisting of a corrugated aluminum sheet on one side of which has deposited at least one layer consisting of bitumen or a bitumen-based compound.

Par rapport à l'art antérieur décrit ci-dessus le matériau complexe utilisé selon l'invention est caractérisé en ce qu'il comporte une feuille d'aluminium ondulée dans un seul sens ; c'est dire que le matériau complexe utilisé,s'il peut s'enrouler sur lui-même pour donner naissance à un cylindre dont les génératrices sont parallèles aux ondulations de l'aluminium, présente dans les sens des ondulations une rigidité certaine. On choisira l'épaisseur de la feuille d'aluminium et la forme des ondulations de cette feuille pour avoir une rigidité longitudinale suffisante de matériau.Compared to the prior art described above, the complex material used according to the invention is characterized in that that it has a corrugated aluminum sheet in one direction only; that is to say that the complex material used, if it can be wound on itself to give birth to a cylinder whose generatrices are parallel to the corrugations of aluminum, presents in the directions of the corrugations a certain rigidity. We will choose the thickness of the aluminum sheet and the shape of the corrugations of this sheet to have sufficient longitudinal stiffness of material.

La feuille d'aluminium ondulée pourra être revêtue de bitume sur une de ses faces ou sur ses deux faces ; il sera également possible, soit directement sur la face de la feuille d'aluminium non revêtue de bitume, soit sur la surface du bitume, de disposer un matériau décoratif (tel que granulés minéraux colorés, paillettes d'ardoises sur la surface de bitume ou couleur, ou revêtement décoratif sur la surface de l'aluminium).The corrugated aluminum sheet may be coated with bitumen on one of its faces or on both of its faces; it will also be possible, either directly on the face of the aluminum sheet not coated with bitumen, or on the surface of the bitumen, to have a decorative material (such as colored mineral granules, flakes of slate on the surface of bitumen or color, or decorative coating on the aluminum surface).

La couche de bitume pourra être adhésive en elle-même ou être rendue adhésive par tout moyen (chauffage par exemple) lors de sa mise en place ; mais il est également possible de fixer le matériau composite sur la toiture en utilisant une colle compatible avec le bitume.The bitumen layer may be adhesive in itself or be made adhesive by any means (heating for example) during its installation; but it is also possible to fix the composite material on the roof using an adhesive compatible with bitumen.

La ou les couches de bitume ou de composé à base de bitume utilisées pourront comporter des fibres ou une toile qui, comme connu, sont souvent employées comme élément-de renforcement.The layer or layers of bitumen or bitumen-based compound used may include fibers or a fabric which, as known, are often used as a reinforcing element.

Le procédé selon l'invention est caractérisé en ce que l'on dépose et l'on colle par une face revêtue debitume sur la to- ture sèche, le matériau composite selon l'invention en prenant soin que les lignes d'ondulation de la feuille d'aluminium soient perpendiculaires à la pente du toit (donc sont horizontales).The method according to the invention is characterized in that the composite material according to the invention is deposited and bonded by a surface coated with bitumen to the dry structure, taking care that the corrugation lines of the aluminum foil are perpendicular to the slope of the roof (so are horizontal).

On obtient ainsi à la fois d'une part une réparation de la toiture sèche et d'autre part un renforcement de ladite toiture.This gives both a repair of the dry roof on the one hand and a reinforcement of the said roof on the other.

Dans l'exemple non limitatif ci-après on décrit un mode de mise en oeuvre de l'invention. Cet exemple se réfère à la figure unique.In the nonlimiting example below, an embodiment of the invention is described. This example refers to the single figure.

Sur cette figure unique on a représenté un rouleau de matériau utilisable pour la mise en oeuvre du procédé selon l'invention. Ce matériau comporte en 1 sur une feuille d'aluminium ondulée et en 2 une couche de bitume (ou d'un mélange de bitume avec au moins un additif présentant un certain pouvoir collant). Sur cette figure on a également fait figurer en 3 la toiture sèche sur laquelle le matériau doit être collé. On voit que le matériau est déroulé de façon que les ondulations de la feuille d'aluminium 2 soient perpendiculaires (ou sensiblement perpendiculaires) à la direction des ondulations de la toiture sèche 3.This single figure shows a roll of material usable for implementing the method according to the invention. This material comprises in 1 on a corrugated aluminum sheet and in 2 a layer of bitumen (or a mixture of bitumen with at least one additive having a certain tackiness). This figure also shows in 3 the dry roof on which the material is to be glued. It can be seen that the material is unwound so that the corrugations of the aluminum sheet 2 are perpendicular (or substantially perpendicular) to the direction of the corrugations of the dry roof 3.
