Abstract

System for thermal insulation and leakproofing of roofing according to Claim 1 of the main patent. The first leakproofing layer which is self-adhesive when cold is produced by application of leakproofing sheets comprising a bottom face which is self-adhesive over their whole surface with the exception of a heat-weldable strip situated at the edge, unilaterally, and forming part of the selvage for overlapping the said sheets, the other part of which is self-adhesive, this strip being heat-welded once the self-adhesive sheets have been laid. This system finds its application in the leakproofing of roofing.

Description

La présente invention a pour objet un perfectionnement au système d'isolation et d'étanchéisation des toitures qui fait l'objet du brevet principal. The present invention relates to an improvement to the roof insulation and sealing system which is the subject of the main patent.

Le système décrit dans le brevet principal consiste à fixer sur le support à protéger des plaques de polystyrène expansé au moyen d'une colle à froid, puis à appliquer sur ces plaques, également à froid, une première couche d'étanchéité auto-adhésive et enfin à recouvrir cette première couche par une seconde couche d'étanchéité soudée au chalumeau. The system described in the main patent consists in fixing on the support to be protected expanded polystyrene sheets by means of a cold glue, then in applying on these sheets, also cold, a first layer of self-adhesive sealing and finally to cover this first layer with a second sealing layer welded with a torch.

Si ce système représente un progrès appréciable par rapport à ceux précédemment existants, sa mise en oeuvre comporte toutefois le risque que l'autocollage de la première couche d'étanchéité ne se fasse pas immédiatement en raison en particulier de conditions atmosphériques défavorables, ou pour toute autre raison. Il s'ensuit que la première couche d'étanchéité peut ne pas être complétement étanche, notamment aux jonctions des feuilles, ce qui nuit à la qualité de protection du système. If this system represents an appreciable progress compared to those previously existing, its implementation however involves the risk that the bonding of the first sealing layer will not take place immediately due in particular to unfavorable atmospheric conditions, or for any another reason. It follows that the first sealing layer may not be completely waterproof, in particular at the junctions of the sheets, which affects the quality of protection of the system.

Le perfectionnement qui fait l'objet du présent certificat d'addition vise à remédier à cet inconvénient en proposant un moyen qui garantit l'étanchéité de la première couche d'étanchéité du système décrit au brevet principal. The improvement which is the subject of this addition certificate aims to remedy this drawback by proposing a means which guarantees the tightness of the first sealing layer of the system described in the main patent.

Le présent perfectionnement consiste à mettre en oeuvre, en vue de constituer la première couche d'étanchéité, des feuilles d'étanchéité comportant en bordure, unilatéralement, un espace soudable à chaud, en sorte que la lisière de recouvrement de chaque feuille soit constituée de deux parties dont l'une, en retrait par rapport à la bordure, est autoadhésive à froid et l'autre, en bordure, est thermosoudable. The present improvement consists in using, in order to constitute the first sealing layer, sealing sheets comprising at the edge, unilaterally, a heat-weldable space, so that the covering edge of each sheet is made up of two parts, one of which, set back from the edge, is self-adhesive cold and the other, at the edge, is heat sealable.

L'avantage inhérent au présent perfectionnement réside dans le fait que la partie auto-adhésive de la lisière de recouvrement assure une étanchéité suffisante de la première couche d'étanchéité jusqu'au soudage à chaud de l'autre partie, lequel garantit la parfaite étanchéité de ladite couche. The advantage inherent in the present improvement resides in the fact that the self-adhesive part of the covering edge provides sufficient sealing of the first sealing layer until the heat sealing of the other part, which guarantees perfect sealing. of said layer.

La présente invention va être maihtenant décrite en référence au dessin annexé, qui représente une coupe d'un système d'isolation et d'étanchéité selon l'invention, étant bien entendu que cette description ne présente aucun caractère limitatif. The present invention will now be described with reference to the accompanying drawing, which shows a section through an insulation and sealing system according to the invention, it being understood that this description has no limiting character.

Sur le dessin annexé, on voit le support 1 à protéger recouvert d'un isolant thermique 2 sur lequel est appliquée une première couche d'étanchéité formée de feuilles 3 et 4 comportant une sous-face adhésive 5. La lisière de recouvrement des feuilles 3 et 4 est formée d'une partie 5' auto-adhésive et d'une partie 6 soudée à chaud. La première couche d'étanchéité 3-4 est recouverte par une seconde couche d'étanchéité 7 soudée à chaud. In the appended drawing, the support 1 to be protected is seen covered with a thermal insulator 2 to which a first sealing layer formed of sheets 3 and 4 is applied comprising an adhesive underside 5. The edge covering sheets 3 and 4 is formed by a self-adhesive part 5 ′ and by a hot-welded part 6. The first sealing layer 3-4 is covered by a second sealing layer 7 heat welded.

La présente invention a également pour objet les feuilles d'étanchéité mises en oeuvre pour constituer la première couche d'étanchéité du système d'étanchéisation perfectionné qui en constitue le premier objet. The present invention also relates to the sealing sheets used to constitute the first sealing layer of the improved sealing system which constitutes its first object.

Les feuilles d'étanchéité selon l'invention présentent la caractéristique de comporter une face inférieure auto-adhésive sur toute sa surface, à l'exception d'un galon thermosoudable situé en bordure, unilatéralement, et constituant partie de la lisière de recouvrement desdites feuilles, l'autre partie étant autoadhésive. The sealing sheets according to the invention have the characteristic of having a self-adhesive lower face over its entire surface, with the exception of a heat-sealable strip located at the edge, unilaterally, and constituting part of the edge of overlap of said sheets. , the other part being self-adhesive.

La face auto-adhésive des feuilles selon l'invention est protégée par une feuille de protection détachable au moment de l'emploi, telle qu'une feuille de papier siliconé ou une feuille de polypropylène siliconé. The self-adhesive face of the sheets according to the invention is protected by a protective sheet which can be removed at the time of use, such as a sheet of silicone paper or a sheet of silicone polypropylene.

Les feuilles d'étanchéité selon l'invention sont de préférence réalisées en un matériau à base de bitume oxydé ou de bitume modifié par des polymères, renforcé par une armature en fibres organiques telles que des fibres de polyester non tissées. The sealing sheets according to the invention are preferably made of a material based on oxidized bitumen or on bitumen modified by polymers, reinforced by a reinforcement of organic fibers such as nonwoven polyester fibers.

Le galon ménagé en bordure des feuilles d'étanchéité selon l'invention a de préférence une largeur de l'ordre de 5 cm, approximativement égale à la moitié de la largeur de la lisière de recouvrement, laquelle est généralement large de 8 à 12 cm. Il peut être avantageusement recouvert d'un film d'une matière synthétique thermo-fusible, telle que le polypropylène ou le polyéthylène, destiné à en faciliter le soudage.  The braid formed at the edge of the sealing sheets according to the invention preferably has a width of the order of 5 cm, approximately equal to half the width of the covering edge, which is generally 8 to 12 cm wide. . It can advantageously be covered with a film of a heat-fusible synthetic material, such as polypropylene or polyethylene, intended to facilitate welding.
