Description
La présente invention a pour objet un nouveau procédé de fixation de feuilles d'étanchéité à base de bitume, ainsi que les nouvelles feuilles d'étanchéité mises en oeuvre dans ce procédé.The present invention relates to a new process for fixing bitumen-based waterproofing sheets, as well as the new waterproofing sheets used in this process.
Parmi les systèmes connus à ce jour pour réaliser l'étanchéité des toitures, l'un des plus couramment utilisés consiste à mettre en oeuvre un revêtement bitumineux fixé mécaniquement sur le support à protéger au moyen de vis ou de rivets régulièrement espacés le long de son galon de recouvrement.Among the systems known to date for sealing roofs, one of the most commonly used consists in using a bituminous coating mechanically fixed on the support to be protected by means of screws or rivets regularly spaced along its covering braid.
Un tel système n'est cependant pas sans inconvénient, la fixation mécanique du revêtement entraînant des risques de perforation par les vis ou les rivets mis en oeuvre, par suite du tassement du support et/ou des mouvements de la structure du bâtiment.However, such a system is not without drawbacks, the mechanical fixing of the covering giving rise to risks of perforation by the screws or the rivets used, as a result of the compaction of the support and / or of the movements of the structure of the building.
Afin de remédier à cet inconvénient on a proposé de disposer sur la feuille de bitume en cours de pose, aux emplacements des vis ou rivets servant à sa fixation, des auxiliaires de fixation tels que des rondelles ou plaquettes métalliques. Toutefois ce procédé présente le désavantage de créer une hétérogénéité entre la feuille de bitume souple et les moyens de fixation rigides, entraînant la possibilité de formation de plis entre deux fixations consécutives, avec à la clé des risques de déchirure de la feuille.In order to remedy this drawback, it has been proposed to have fixing aids on the bitumen sheet during installation, at the locations of the screws or rivets used for fixing it, such as metal washers or plates. However, this method has the disadvantage of creating heterogeneity between the flexible bitumen sheet and the rigid fixing means, resulting in the possibility of folds forming between two consecutive fastenings, with the risk of tearing the sheet.
En outre, l'utilisation de rondelles ou de plaquettes métalliques entraîne la formation de protubérances locales et augmente le temps nécessaire à la fixation de la feuille d'étanchéité sur le support à recouvrir du fait de la mise en oeuvre d'un grand nombre d'auxiliaires de fixation indépendants.In addition, the use of washers or metal plates leads to the formation of local protuberances and increases the time necessary for fixing the sealing sheet to the support to be covered due to the use of a large number of independent fixing aids.
Par le document US-A-2 305 008, on connaît déjà un revêtement pour toitures constitué de feuilles à base de bitume comportant des bords de jointure renforcés et rigidifiés par des bandes métalliques perforées, pouvant être recourbées en U.From document US-A-2 305 008, a covering for roofs is already known which consists of bitumen-based sheets having reinforced joint edges and stiffened by perforated metal strips, which can be bent in a U shape.
Ces feuilles de revêtement sont, par conséquent, accrochées entre elles par repliements interpénétrants de leurs bords de jointure et sont fixées sur le support à recouvrir au moyen de clous.These covering sheets are therefore hooked together by interpenetrating folds of their joint edges and are fixed to the support to be covered by means of nails.
Néanmoins, ces bandes métalliques et le mode d'accrochage des feuilles entre elles, créent des surépaisseurs importantes au niveau des jointures.However, these metal strips and the way in which the sheets are attached to each other, create significant thicknesses at the joints.
En outre, ces bandes métalliques planes ne peuvent épouser les déformations des feuilles de revêtement auxquelles elles sont solidarisées, et n'autorisent pas l'enroulement de ces dernières.In addition, these flat metal strips cannot match the deformations of the covering sheets to which they are attached, and do not allow the latter to be wound.
De plus, la mise en oeuvre de ces feuilles de revêtement, au moment de leur pose, est complexe et fastidieuse, surtout pour les feuilles de grandes dimensions, et la réalisation de plis multiples au niveau des jointures entraîne des pertes importantes de surface utile de revêtement au niveau de chaque feuille d'étanchéité.In addition, the implementation of these covering sheets, at the time of their installation, is complex and tedious, especially for sheets of large dimensions, and the production of multiple folds at the joints results in significant losses of useful surface area. coating at each sealing sheet.
Par ailleurs, les éléments de fixation utilisés ne sont par recouverts et ne bénéficient d'aucune protection contre les agents corrosifs extérieurs.Furthermore, the fastening elements used are not covered and do not benefit from any protection against external corrosive agents.
La présente invention a pour but de remédier à ces divers inconvénients des systèmes de fixation connus des feuilles d'étanchéité en proposant un procédé de fixation d'une feuille d'étanchéité à base de bitume qui permet d'éviter tout risque de perforation ou de déchirure de ladite feuille, ce tout en réalisant une fixation homogène de cette dernière et en ne mettant en oeuvre aucun auxiliaire de fixation supplémentaire.The object of the present invention is to remedy these various drawbacks of known fixing systems for sealing sheets by proposing a method for fixing a bitumen-based sealing sheet which makes it possible to avoid any risk of perforation or tearing of said sheet, while achieving a homogeneous fixing of the latter and not using no additional fixing aid.
En outre, la fixation réalisée devra pouvoir épouser les déformations de la feuille, ne pas créer de surépaisseurs et limiter au maximum la perte de surface utile de revêtement de chaque feuille, notamment pour une économie au niveau du recouvrement des feuilles adjacentes.In addition, the fixing carried out must be able to conform to the deformations of the sheet, not to create excess thicknesses and to limit as much as possible the loss of useful surface area for coating each sheet, in particular for an economy in terms of covering the adjacent sheets.
La présente invention a ainsi pour premier objet un procédé de fixation d'une feuille d'étanchéité à base de bitume, ce procédé consistant, soit lors de la pose de la feuille d'étanchéité sur le support à recouvrir, soit lors de la fabrication de ladite feuille, à mettre en place sur le galon de recouvrement de la feuille d'étanchéité, à courte distance de sa bordure, une bande métallique de faible épaisseur comportant des cannelures transversales et des perçages disposés à intervalles réguliers sur toute sa longueur, puis à fixer ladite feuille d'étanchéité sur le support à recouvrir par l'intermédaire de ladite bande métallique au moyen de vis ou de rivets correspondants.The present invention thus has for first object a method of fixing a bitumen-based waterproofing sheet, this process consisting, either during the laying of the waterproofing sheet on the support to be covered, or during the manufacturing of said sheet, to be placed on the covering strip of the sealing sheet, a short distance from its edge, a thin metal strip comprising transverse grooves and bores arranged at regular intervals over its entire length, then fixing said sealing sheet to the support to be covered by means of said metal strip by means of screws or corresponding rivets.
La mise en oeuvre d'une telle bande métallique permet de créer une homogénéité entre la feuille d'étanchéité et ses moyens de fixation, les efforts qui sollicitent habituellement les revêtements d'étanchéité étant transmis par ladite bande métallique d'une fixation à l'autre.The use of such a metal strip makes it possible to create a homogeneity between the sealing sheet and its fixing means, the forces which usually stress the sealing coatings being transmitted by said metal strip from a fixing to the other.
Le procédé selon l'invention permet ainsi, non seulement d'écarter les risques de perforation de la feuille au voisinage de ses points de fixation mécanique, mais encore les risques de déchirure par suite de formation de plis entre les fixations, la bande métallique assurant une solution de continuité entre les fixations et ses cannelures transversales lui permettant d'épouser les déformations de la feuille d'étanchéité, que ces déformations soient dues à des sollicitations mécaniques ou à des phénomènes thermiques.The method according to the invention thus makes it possible not only to avoid the risks of perforation of the sheet in the vicinity of its mechanical fixing points, but also the risks of tearing as a result of the formation of folds between the fasteners, the strip metal ensuring a solution of continuity between the fasteners and its transverse grooves allowing it to match the deformations of the sealing sheet, whether these deformations are due to mechanical stresses or to thermal phenomena.
Conformément à l'invention, la bande métallique mise en oeuvre dans le procédé qui en fait l'objet est solidarisée à la feuille d'étanchéité par autocollage à chaud au cours de sa fabrication.According to the invention, the metal strip used in the process which is the subject of it is secured to the sealing sheet by hot-stamping during its manufacture.
L'invention a également pour objet une feuille d'étanchéité à base de bitume, destinée à être mise en oeuvre notamment dans le procédé précité et comportant, au niveau de sa bordure, une bande métallique pourvue de perçages pour sa fixation sur le support à recouvrir, caractérisé en ce que ladite bande métallique, de faible épaisseur, est, d'une part, fixée sur le galon de recouvrement de ladite feuille d'étanchéité à courte distance de sa bordure, de manière à laisser une bande de soudure, et comporte, d'autre part, des cannelures transversales disposées, de même que les perçages, à intervalles réguliers sur toute sa longueur.The subject of the invention is also a bitumen-based sealing sheet, intended to be used in particular in the aforementioned process and comprising, at its edge, a metal strip provided with holes for its fixing on the support to cover, characterized in that said thin metal strip is, on the one hand, fixed to the covering strip of said sealing sheet a short distance from its edge, so as to leave a weld strip, and comprises, on the other hand, transverse grooves arranged, as well as the holes, at regular intervals over its entire length.
La bande métallique précitée doit présenter une résistance mécanique suffisante ainsi qu'une résistance élevée à la flexion, devant répondre à l'exigence d'être robuste en faible épaisseur de manière à permettre l'enroulement des feuilles d'étanchéité.The aforementioned metal strip must have sufficient mechanical strength as well as high flexural strength, which must meet the requirement of being robust in thin thickness so as to allow the winding of the sealing sheets.
Pour l'ensemble de ces raisons, elle est avantageusement constituée d'une bande d'acier inoxydable ou inox dont l'épaisseur est comprise entre 5/100 mm et 16/100 mm et la largeur entre 2 et 3 cm, comportant sur toute sa longueur des cannelures transversales distantes de 1 à 1,5 cm, dont la largeur est comprise entre 2 et 3 cm et la profondeur entre 0,5 et 1 mm, et comportant en outre des perçages disposés à intervalles réguliers, par exemple tous les 5 cms.For all of these reasons, it advantageously consists of a strip of stainless steel or stainless steel whose thickness is between 5/100 mm and 16/100 mm and the width between 2 and 3 cm, comprising on any its length of the
Cette bande métallique est disposée sur le galon de recouvrement de la feuille d'étanchéité, de préférence à environ 2 cm de sa bordure.This metal strip is placed on the strip covering the sealing sheet, preferably about 2 cm from its edge.
Le procédé et la feuille d'étanchéité selon l'invention offrent l'avantage d'être d'une grande facilité de mise en oeuvre, en raison des perçages dont la bande métallique est munie, et de ne pouvoir donner lieu à des erreurs de pose du fait que ladite bande métallique fait partie intégrante de la feuille d'étanchéité.The method and the sealing sheet according to the invention offer the advantage of being very easy to implement, because of the holes with which the metal strip is provided, and of being unable to give rise to errors of poses the fact that said metal strip is an integral part of the sealing sheet.
Ils offrent également l'avantage de permettre une économie de recouvrement par rapport aux procédés traditionnels, la bande métallique de fixation autorisant la mise en oeuvre d'un galon de recouvrement plus étroit (de l'ordre 6 cm), les rondelles ou plaquettes mises en oeuvre dans les procédés traditionnels entrainant la nécessité d'un recouvrement qui les déborde assez. largement et dont la largeur est généralement de l'ordre de 7 cm.They also offer the advantage of allowing an economy of recovery compared to traditional methods, the metal fixing strip allowing the implementation of a covering strip. narrower (of the order of 6 cm), the washers or plates used in the traditional processes causing the need for a covering which overflows them enough. widely and whose width is generally of the order of 7 cm.
Le procédé de l'invention est applicable à toutes les feuilles d'étanchéité à base de bitume, et il est particulièrement approprié aux recouvrements en monocouche, en raison de l'économie de recouvrement qu'il autorise.The process of the invention is applicable to all bitumen-based waterproofing sheets, and it is particularly suitable for monolayer coverings, because of the economy of recovery which it allows.
La présente invention sera mieux comprise à la lecture de la description qui suit, faite en regard du dessin schématique annexé, lequel en représente un mode de réalisation non limitatif.The present invention will be better understood on reading the description which follows, given with reference to the appended schematic drawing, which represents a non-limiting embodiment thereof.
Dans le dessin annexé :
- - la figure 1 représente une vue en perspective du galon de recouvrement d'une feuille d'étanchéité selon l'invention ;
- la figure 2 représente une vue en coupe de la même feuille, selon la ligne XX' de la figure 1.
- - Figure 1 shows a perspective view of the cover strip of a sealing sheet according to the invention;
- 2 shows a sectional view of the same sheet, along the line XX 'of Figure 1.
Si on se réfère d'abord à la figure 1, on voit que le galon de recouvrement 1 d'une feuille d'étanchéité selon l'invention comporte, à 2 cm de sa bordure, une bande métallique 2 large de 2 cm munie de cannelures 3, régulièrement réparties sur toute sa longueur, distantes d'environ 1,5 cm les unes des autres, et de perçages 4 ménagés sur toute sa longueur, à intervalles réguliers.If we refer first to Figure 1, we see that the
Si on se réfère ensuite à la figure 2, on voit que les cannelures 3 ménagées dans la bande métallique 2 pénètrent dans le galon de recouvrement 1, auquel la bande métallique 2 a été solidarisée par autosoudage à chaud au cours de la fabrication de la feuille d'étanchéité.If we then refer to Figure 2, we see that the
Les cannelures 3 de la bande métallique 2 favorisent sa solidarisation au galon de recouvrement 1 de la feuille d'étanchéité en augmentant la surface de contact entre les deux, et d'autre part, elles permettent à la bande 2 d'épouser les déformations de la feuille, écartant de ce fait les risques de déchirure de cette dernière.The
Ainsi, lesdites cannelures 3, avantageusement réalisées sous forme de déformations locales de la bande métallique 2, notamment sous forme de déformations en V, absorbent les différentes tensions auxquelles est soumise la bande métallique 2, tant en dilatation qu'en contraction.Thus, said
La bande métallique 2 peut être mise en place sur le galon de recouvrement 1 de la feuille d'étanchéité, soit lors de la fabrication de cette dernière, soit lors de sa pose et de sa fixation sur le support à recouvrir et à protéger.The
Néanmoins, selon un mode de réalisation préféré de l'invention, la bande métallique 2, munie des cannelures 3 et des perçages 4, est solidarisée par autocollage ou autosoudage à chaud au galon de recouvrement 1 de la feuille d'étanchéité lors de la fabrication de cette dernière.However, according to a preferred embodiment of the invention, the
Elle pourra, par exemple, être noyée dans la masse bitumineuse du galon de recouvrement 1, lorsque celle-ci est encore visqueuse, de telle manière qu'elle soit affleurante par rapport à la surface dudit galon de recouvrement 1.It could, for example, be embedded in the bituminous mass of the
Ainsi, la bande métallique 2 permet également d'éviter les amorces de déchirures le long des bords de la feuille d'étanchéité, au cours du transport, de la manipulation et de la pose de cette dernière, et peut, en outre, servir de repère de pose et de fixation de ladite feuille d'étanchéité. De plus, les cannelures 3, constituant des zones de pliage préférentielles, autorisent un enroulement aisé de ladite bande métallique 2 ensemble avec la feuille d'étanchéité. Par ailleurs, du fait de la très faible épaisseur de la bande métallique 2 et de son mode de solidarisation qui l'intègre au galon de recouvrement 1, ladite bande métallique 2 est affleurante au niveau dudit galon de recouvrement 1 et ne donne lieu à aucune protubérance ou surépaisseur.Thus, the
Grâce à l'invention, il est, par conséquent, possible de concevoir un procédé de fixation d'une feuille d'étanchéité bitumineuse, ainsi qu'une feuille d'étanchéité correspondante, permettant d'éviter tout risque de perforation ou de déchirure de ladite feuille, et ce tout en réalisant une fixation homogène de cette dernière et en ne mettant en oeuvre aucun auxiliaire de fixation supplémentaire.Thanks to the invention, it is therefore possible to design a method for fixing a bituminous waterproofing sheet, as well as a corresponding waterproofing sheet, making it possible to avoid any risk of perforation or tearing of said sheet, and this while achieving a homogeneous fixing of the latter and not using any additional fixing aid.
