FR2625760A1 - Waterproofing plate device (damp proofing tray) for roofing forming a chimney support - Google Patents

Abstract

It consists in the combination of firstly a plate 1 forming the support, parallelepipedal in shape and flat, with lateral walls with their edges turned down 4, 5, and then transverse walls 6 onto which joist fillers 7, 9 or flexible metal plates are fixed dressed over the shape of the bearing surfaces by lapping or insertion without edge joints. It is designed to allow rapid fixing and sealed assembly of all types of tiles or roofs.

Description

 Sealing plate device for roof forming chimney support.

 It is intended to allow rapid installation with watertight assembly on all types of tiles or roofs.

 Until now to allow the installation of a chimney support on a tiled or other roof, it was necessary to make a flange using a sealing plate or the like which was placed under the tiles and on this base the pipe was fixed, you never got a perfect seal and moving the tiles over very large areas required a lot of work.

 The device according to the invention eliminates these drawbacks and makes it possible to produce a universal support adapting to all types of roofs or tiles and ensuring during its installation a perfect joint with the tiles both on the anterior as well as on the posterior and lateral faces. , this flashing takes the form of a flexible metal strip such as lead, filling the intermediate space between the plate and the slope of the roof, connecting the surfaces and preventing infiltration, all using preposition elements born and with so-called universal adaptation.

 It is constituted by the combination first of a plate forming a support of parallelepipedal and planar shape with side walls with drooping edges, then by transverse walls on which are fixed flashings or flexible metal plates adapting to the profiles of the bearing surfaces by covering or penetration without contiguous overflows.

In the accompanying drawings given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figures 1 and 2 show perspective views of the waterproof cover plates forming chimney supports.

 Figure 3 is a schematic view showing one of the possible positions of these plates.

 The support, FIGS. 1, 2, 3, is formed by a plate or flat surface 1 comprising at its central part an orifice 2 on which the chimney 3 is fixed.

 The side faces have parallel drooping edges 4, 5, corresponding to the hollow parts separating the rows of protruding tiles.

 The front face 6 has a falling edge on which a lead flashing 7 or similar is fixed with cutout 8 adapted to the profile of the tiles and covers them.

 The rear face also receives a flashing 9 covering with profiled end 10 to pass under the tiles.

 The assembly can be just as well prefabricated as adapted on site.

 The connections 11, 12 can be made both by welding and by pinching in grooves or crimping.

Plate 1 is placed on the tile whatever its shape, flat, round, corrugated cement surface or even corrugated sheet
The front and rear flashings are made of flexible plates which conform to the shape of the tile by simple forming.

 This plate 13, shown in Figure 3, has its lateral drooping edges, 16, 17, plunging into the channels 14, 15, formed by the lower tiles.

 Its front face covers by the flashing 18 the tiles 19, 20, 21 thus ensuring the sealing of the covering.

 On the other hand, the rear flashing 22 penetrates under the tiles 23, 24, 25 which cover it and thus eliminates any possibility of infiltration.

This plate 1 can be entirely prefabricated, the flashings 9 and 6 assembled and the chimney 3 mounted so that the operator only has to remove the tiles for the passage of the pipe and place the flashings on the tiles before 19, 20, 21 and under the rear tiles 23, 24, .25,
The falling edges 16, 17 penetrating at the bottom of the channels 14, 15 ensure a connection without solution of continuity of covering, joining and falling contacts, which gives this universal plate, that is to say adaptable to all roofs, a absolute watertightness without cementing or making masonry footings or interposing cover plates.

This assembly can also be performed on site
and the connections 11, 12 obtained either by welding or by crimping
wise or any other known means.

 The device can be used for equivalent applications or an assembly with the roof is necessary, such as roof windows.

 However, the shapes, dimensions and arrangements of the various elements may vary as well as the materials used for their manufacture without changing for this, the general design of the invention which has just been described.

Claims (1)

 10 Sealing plate device for the roof forming a chimney support, the purpose of which is to allow rapid and tight assembly without masonry or other work on all types of roofs or tiles by direct laying, characterized by the combination of a plate parallelepiped (1) with central orifice receiving a chimney (3) laterally provided with falling edges (4, 5) having on the transverse walls either falling edges (6) or connection profiles (11, 12) connecting them to plates in malleable metal or flashing (7, 9) preferably in lead with on-site forming (8) covering at the front and placed under the tiles at the rear according to the slope of the roof.  29 Device according to Claim 1, characterized in that the lateral drooping edges (16, 17) of the plate (13) plunge into the channels (14, 15) while the front flashing (18) covers the tiles (19, 20, 21) and that the rear flashing (22) has passed under the opening tiles (23, 24, 25).
