Description

The present invention relates to a device for fixing a covering profile on a wall ridge, and more particularly on a wall ridge coated with an insulation complex.

It also relates to a system for covering a wall ridge comprising at least one covering profile mounted on such fixing devices, as well as to assembling such a roofing system on a ridge of wall and to a method of mounting such a cover system.

To effectively cover the ridge of a wall, corresponding to the top, parapet or upper edge of the wall, and thus protect it from the weather and infiltrations, it is known to fix on this ridge covering profiles, sometimes called screen. protection, covering, cover, crown or chaperone, which are generally made of "U" -shaped sheets and whose lateral parts are sufficiently long to protrude down the edge of the wall.

For walls of great length, and in particular the acroterium walls which border the entire perimeter of a roof or terrace, it is customary to mount on the ridge of the wall several P profiles of overlap placed end to end, as visible in figure 1 .

It is customary to fix the covering profiles, or the slats for holding the covering profiles, on intermediate parts which are screwed directly to the ridge of the wall by means of several screws.

However, the use of these intermediate parts has many disadvantages in the case where the wall ridge is coated with an insulation complex, conventionally made of an insulation layer covered with a waterproofing membrane, for thermal insulation of the wall from the outside.

Indeed, the fixing operations of these intermediate parts on the wall ridge are strongly impacted by the presence of the insulation complex, because it is then the obligation to cross the insulation complex, and in particular to make cuts multiples of the insulation complex to be able to put the intermediate pieces on the ridge of wall. Such cuts induce thermal bridges detrimental to the thermal insulation of the wall, and further contribute to increase the time and thus the costs of implementation of the covering profiles.

It is also known from the document US 2,554,779 A , to ensure the fixing of a covering profile on a wall ridge by employing a ramp-shaped rail fixed to the ridge by means of a screw, the covering profile being itself fixed on the rail by two screw. However, such a rail has a particularly narrow bearing surface, the risk of damaging a possible complex insulation placed on the wall ridge under the constraint of the screws during assembly.

The object of the present invention is to overcome these drawbacks by proposing a device for fixing a covering profile on a wall ridge coated with an insulation complex, which has a reduced impact on the insulation complex, thus limiting the thermal bridges, and which provides stability and increased mechanical strength.

• une cale présentant une face d'appui sur ledit complexe d'isolation et un orifice traversant, et comportant des moyens de montage du profilé de recouvrement sur ladite cale constitués d'au moins deux orifices filetés débouchant sur une face supérieure de la cale, à l'opposé de la face d'appui, ladite face supérieure présentant deux zones d'appui pour le profilé de recouvrement ou pour une coulisse de maintien du profilé ; et
• une vis unique de fixation de la cale sur le faîte de mur, ladite vis traversant ledit orifice traversant de la cale et étant conformée pour traverser ledit complexe d'isolation pour une fixation sur le faîte de mur ;

ce dispositif étant remarquable en ce que la cale présente deux bossages faisant saillie d'une embase plate définissant ladite face d'appui, avec un premier bossage définissant une première zone d'appui dans laquelle est ménagé un premier orifice fileté et un second bossage définissant une seconde zone d'appui dans laquelle est ménagé un second orifice fileté, le second bossage présentant une hauteur supérieure à celle du premier bossage afin d'assurer une pente du profilé de recouvrement et/ou de la coulisse par rapport à l'horizontale.For this purpose, it proposes a device for fixing a covering profile on a wall ridge coated with an insulation complex, comprising:

• a wedge having a bearing surface on said insulation complex and a through orifice, and comprising means for mounting the cover profile on said wedge constituted by at least two threaded holes opening on an upper face of the wedge, the opposite of the bearing face, said upper face having two support zones for the cover profile or for a profile holding slide; and
• a single screw for fixing the wedge on the wall ridge, said screw passing through said through orifice of the wedge and being shaped to pass through said insulation complex for attachment to the wall ridge;

this device being remarkable in that the wedge has two bosses projecting from a flat base defining said bearing face, with a first boss defining a first bearing zone in which is formed a first threaded orifice and a second boss defining a second bearing zone in which is formed a second threaded orifice, the second boss having a height greater than that of the first boss to ensure a slope of the cover profile and / or the slide relative to the horizontal.

Thus, thanks to such a fixing device, it is no longer necessary to make a too large cut of the insulation complex, because only a hole is necessary for the passage of the fixing screw. The wedge forms a stable base for the covering profile, coming to bear on the complex insulation and being fixed to the wall ridge via the through screw, thus limiting the thermal bridges.

The cover profile is fixed on the wedge by means of screws cooperating with these threaded orifices, either directly or via a profile holding slide. The shim also makes it possible to create a slope, for example of approximately 2 ° with respect to the horizontal, between the sealing complex on the one hand and the profile and / or the slide on the other hand.

According to one characteristic, the bearing face has an area of between about 50 and 350 cm ² , preferably between about 100 and 200 cm ² .

Such areas are well suited for substantially rigid insulation complexes, such as insulation complexes comprising an insulation layer, polyurethane foam or polystyrene, covered with a waterproofing membrane.

According to another characteristic, the flat base, preferably of small thickness, has a substantially circular shape to ensure an increased area, guaranteeing good stability.

Indeed, for a good balance of the seat formed by the wedge, it is advantageous that the bearing face is substantially circular in shape with a particular diameter of between 8 and 22 cm, preferably between about 11 and 16 cm.

To stiffen the shim, it is advantageous that the wedge has reinforcing ribs projecting from the flat base.

According to a possibility of the invention, the through orifice is formed substantially in the center of the wedge, so that the wedge achieves a well balanced seat for the profile.

According to another possibility of the invention, the wedge is made in one piece, in particular steel.

The invention also relates to a system for covering a wall ridge covered with an insulation complex, said system comprising at least one covering profile mounted on the shims of at least two fastening devices according to the invention. said fixing devices being spaced apart from one another along the profile.
