Description

La présente invention concerne un dispositif permettant de rendre étancheThe present invention relates to a device for sealing

une couverture existante en plaques ondulées métalliques ou en  an existing roof in metallic corrugated sheets or

fibre ciment et sans effectuer de percement dans celles-ci.  fiber cement and without drilling into them.

Traditionnellement la mise en place d'une protection étanche de 5 type surtoiture isolante sur les couvertures de cette nature nécessite soit de dévisser les écrous des fixations existantes (4) ce qui est impossible ou très difficile à cause de l'état de corrosion de celles-ci, soit de percer les plaques formant la couverture pour se fixer sur elles ou pour atteindre la charpente du bâtiment.  Traditionally the installation of a waterproof protection of the type 5 insulating over-roofing on roofs of this nature requires either to unscrew the nuts of the existing fasteners (4) which is impossible or very difficult because of the state of corrosion of those -this, either to drill the plates forming the cover to fix on them or to reach the frame of the building.

Les plaques en fibre ciment sont composées de fibres d'amiante, ce qui, en cas de percement, oblige la prise de nombreuses précautions conformément à la réglementation en vigueur.  The fiber cement sheets are composed of asbestos fibers, which, in the event of piercing, requires that many precautions be taken in accordance with the regulations in force.

Cela implique entre autre l'enlèvement ou la protection de tous les objets entreposés dans le bâtiment et l'interdiction à toute personne de 1 5 pénétrer dans les locaux traités, sans équipements spéciaux.  This implies, among other things, the removal or protection of all objects stored in the building and the prohibition of any person from entering the treated premises, without special equipment.

Cette évacuation cause un préjudice important à l'utilisateur de l'immeuble qui devra dans la plupart des cas effectuer une décontamination générale après travaux.  This evacuation causes significant damage to the user of the building, who in most cases will have to carry out general decontamination after work.

Cette sur-toiture remédie à cet inconvénient. Elle permet 20 d'effectuer les travaux d'étanchéité sans percement des plaques support contenant des particules d'amiante et donc de maintenir l'activité à l'intérieur du bâtiment.  This roofing overcomes this drawback. It makes it possible to carry out the sealing work without piercing the support plates containing asbestos particles and therefore to maintain the activity inside the building.

Elle comprend l'apport d'une isolation généralement en panneau rigide et d'une étanchéité.  It includes the contribution of insulation generally in rigid panel and sealing.

Le dispositif selon l'invention est caractérisé par l'accrochage du nouveau complexe sur les fixations existantes des plaques ondulées ou nervurées, sans qu'il soit nécessaire de les dévisser.  The device according to the invention is characterized by the attachment of the new complex to the existing fixings of the corrugated or ribbed plates, without the need to unscrew them.

Le dispositif est caractérisé par la réalisation de l'accrochage au moyen de soudure.  The device is characterized by the attachment by means of welding.

Un dispositif connu de ce type permet de prendre ancrage en soudant des prolongateurs sur les fixations existantes des plaques 5 ondulées mais la pose de ces prolongateurs s'avère difficile à réaliser sur un toit. En effet, ce système nécessite de tronçonner au préalable les tiges filetées formant les fixations des plaques. Cette opération est coteuse car elle implique la mise en place d'un platelage pour que le déplacement de l'opérateur puisse se faire en toute sécurité sur les plaques ondulées en 10 fibre-ciment qui sont très fragiles. Les prolongateurs qui sont introduits sur les tiges filétées existantes mise à bonne longueur puis soudés. Pour maintenir le prolongateur dans l'axe de la tige filetée, un dispositif de calage est installé mais sa pose est minutieuse et consommatrice de temps.  A known device of this type makes it possible to take anchorage by welding extensions on the existing fixings of the corrugated plates 5 but the installation of these extensions proves difficult to carry out on a roof. Indeed, this system requires to cut beforehand the threaded rods forming the fastenings of the plates. This operation is expensive because it involves the installation of a deck so that the movement of the operator can be done in complete safety on the corrugated fiber cement sheets which are very fragile. The extensions which are introduced on the existing threaded rods put to good length then welded. To keep the extension in the axis of the threaded rod, a wedging device is installed but its installation is meticulous and time consuming.

Entre les lignes formées par ces prolongateurs, des panneaux isolants sont 15 disposés sur la toiture. Des profils métalliques en forme d'équerre sont posés sur les arêtes des panneaux isolants. Des vis traversant ces équerres doivent être introduites dans les prolongateurs pour y être vissées. Les prolongateurs n'étant pas visibles car noyés dans les panneaux isolant, il est indispensable de repérer leurs emplacements. Malgré cette précaution, 20 l'introduction de la vis dans l'extrémité du prolongateur non visible ne peut s'effectuer qu'à tâtons. Sachant que ces opérations doivent être reproduites deux fois par m2 de toiture soit des milliers de fois pour une toiture, la mise en oeuvre s'avère économiquement impossible.  Between the lines formed by these extenders, insulating panels are placed on the roof. Square-shaped metal profiles are placed on the edges of the insulating panels. Screws passing through these brackets must be inserted into the extensions to be screwed into them. The extenders are not visible because embedded in the insulating panels, it is essential to identify their locations. Despite this precaution, the insertion of the screw into the end of the non-visible extension can only be done by touch. Knowing that these operations must be repeated twice per m2 of roof, ie thousands of times for a roof, the implementation is economically impossible.

Ce dispositif de surtoiture selon l'invention remédie à ces 25 inconvénients de par son concept décrit ci-dessous: Le dispositif prévoit la pose de profils métalliques de section oméga percés sur leur axe longitudinal de trous oblongs. Ces dits profils métalliques sont alignés au dessus des pannes de la charpente du bâtiment de sorte que chaque fixation des plaques ondulées, généralement constituées de tiges filetées et d'écrous, traverse un trou oblong. Des rondelles métalliques percées à un diamètre supérieur à celui des tiges 5 filetées sont introduites dans chacune d'elles puis soudées sur ces dernières. Ces rondelles soudées peuvent être remplacées par des écrous vissés directement sur les tiges filetées si celles-ci sont en bon état. Sinon, il est possible de fileter les fixations existantes des plaques de fibre ciment. La pose de rondelles n'est pas obligatoire, les profils oméga 10 peuvent être soudés directement sur les fixations des plaques fibre ciment.  This over-roofing device according to the invention overcomes these drawbacks by its concept described below: The device provides for the installation of metal profiles of omega section pierced on their longitudinal axis with oblong holes. These so-called metal profiles are aligned above the purlins of the building frame so that each fixing of the corrugated plates, generally made up of threaded rods and nuts, passes through an oblong hole. Metal washers drilled to a diameter greater than that of the threaded rods are introduced into each of them and then welded to the latter. These welded washers can be replaced by nuts screwed directly onto the threaded rods if they are in good condition. Otherwise, it is possible to thread the existing fasteners of the fiber cement sheets. The installation of washers is not compulsory, the omega 10 profiles can be welded directly to the fastenings of the fiber cement sheets.

La forme des profils, leur nature ainsi que le mode d'ancrage peuvent faire l'objet d'autres variantes qui devront par leur nature, offrir une résistance mécanique suffisante pour maintenir la surtoiture en place sous les effets du vent.  The shape of the profiles, their nature and the method of anchoring may be subject to other variants which, by their nature, must offer sufficient mechanical strength to keep the over-roof in place under the effects of the wind.

l 5 Dans ce dispositif, entre les lignes formées par les profils oméga, des panneaux isolants (2) sont posés librement. Un profil métallique en forme d'équerre (3) est placé sur les arêtes des panneaux isolants à l'aplomb des oméga (6). Cette équerre vient serrer les panneaux isolants par l'intermédiaire de vis autotaraudeuses qui la relient à l'oméga. Ainsi, 20 les panneaux isolants et les divers profils métalliques sont devenus solidaires de la toiture. Les équerres qui permettent d'exercer un effort réparti sur le panneau isolant peuvent être remplacées par des points d'ancrage ponctuels réalisés par vis autoforeuses avec rondelles de répartition. Cette variante économique s'avère toutefois satisfaisante 25 quant aux résistances mécaniques qu'elle offre. De nombreuses autres variantes sont possibles.  l 5 In this device, between the lines formed by the omega profiles, insulating panels (2) are placed freely. A metal profile in the form of a square (3) is placed on the edges of the insulating panels directly above the omega (6). This square clamps the insulating panels by means of self-tapping screws which connect it to the omega. Thus, the insulating panels and the various metal profiles have become integral with the roof. The brackets which make it possible to exert a distributed force on the insulating panel can be replaced by punctual anchoring points produced by self-drilling screws with distribution washers. This economic variant is however satisfactory as regards the mechanical strengths which it offers. Many other variations are possible.

T ' 2851275 La surface plane obtenue par la pose des panneaux isolants constitue un support dit admissible selon les règles professionnelles de l'étanchéité pour appliquer un système d'étanchéité en rouleau. Si l'amélioration de l'isolation thermique de la toiture n'est pas souhaitée, les panneaux isolants peuvent être remplacés par tout type de panneaux support offrant la possibilité d'appliquer un système d'étanchéité.  T '2851275 The flat surface obtained by the installation of the insulating panels constitutes a support said to be admissible according to the professional rules of sealing to apply a sealing system in rolls. If the improvement of the thermal insulation of the roof is not desired, the insulating panels can be replaced by any type of support panels offering the possibility of applying a waterproofing system.

Le support ainsi constitué, la pose de la membrane d'étanchéité se fera soit en semi-indépendance par fixations mécaniques, soit en 10 adhérence totale avec des colles.  The support thus formed, the installation of the waterproofing membrane will be done either in semi-independence by mechanical fixings, or in total adhesion with adhesives.

Dans la solution d'une pose en semi-indépendance, les vis autoforeuses qui maintiennent le système d'étanchéité seront vissées dans les équerres primaires (3). Les vis peuvent être remplacées par des rivets.  In the solution of a semi-independent installation, the self-drilling screws which maintain the sealing system will be screwed into the primary brackets (3). The screws can be replaced with rivets.

Dans la solution d'une pose en adhérence, le système d'étanchéité I 5 sera encollé sur toute la surface des panneaux supports (2) afin d'offrir une résistance mécanique maximale aux efforts d'arrachement dus au vent.  In the solution of an adhesion installation, the sealing system I 5 will be glued over the entire surface of the support panels (2) in order to offer maximum mechanical resistance to the tearing forces due to the wind.
