Description

[Detailed description of the invention] This invention relates to a rain control device for the end of the waterproof layer used for exposing exposed waterproofing of flat roofs, and is particularly suitable for use as a rain control device for the eaves without a rising part, which has a draining function and a holding function for the end of the waterproof layer. The present invention relates to a waterproof layer end rain closure device having the following features.

Waterproofing methods for flat roofs include the protective layer waterproofing method, in which a protective layer is provided by placing a concrete holding layer on top of the waterproofing layer, or by spraying gravel, and the exposed waterproofing method, in which the waterproofing layer is exposed. There is a construction method.

Among the exposed waterproofing method and the waterproofing method with a protective layer, flat roofs waterproofed using the so-called gravel penetration method, in which gravel is spread to form a protective layer, may not have a parapet installed.

The ends of the waterproof layer on a flat roof without a parapet are usually accommodated in the manner shown in FIGS. 4 and 5 A, B, and C.

This invention is an improvement and development of the rain cover device of the type shown in FIG. 5 among these devices.

As is clear from Fig. 5A, in this type of rain protection device conventionally used, roof ink a is pasted on the base, and then the waterproof layer fixing member shown in Fig. B is placed on top of it, and the waterproof layer fixing member shown in Fig. A is shown in Fig. Fix it to the base with screws C as shown, and then apply finishing roof ink to the top e of the swash plate d of the waterproof layer fixing member b=! , and then covered with a covering material k shown in Figure 0 and fixed with screws f.

However, the following drawbacks can be pointed out to such conventionally used devices.

That is, (1) The brim g of the waterproof layer fixing member is too short to hold down the waterproof layer around the edge of the frame.

As a result, the end i of the waterproof layer may peel off from the base.

(2) Waterproof layer a attached to swash plate d of waterproof layer fixing member
is fixed with screw f7.

It would be undesirable for the screws f to penetrate through the waterproof layer a, and if the screws f became loose or corroded, rainwater would enter through the screw attachment portions.

This rainwater will leak into the room from the peeled part of the waterproof layer end i that cannot be fixed by the brim g mentioned above.

The purpose of this invention is to solve the problems of the conventionally used waterproof layer end rain closure device for flat roofs without parapets. ,(
2) It is an object of the present invention to provide a waterproof layer end rain closure device that can fix the waterproof layer end portion without using screws f.

The structure of this invention is as follows: (a) a waterproof layer end fixing member 1 that fixes the main waterproof layer 16 and supports the finish waterproof layer 14 at the edge of the flat roof;
(b) The finish waterproof layer 14 is fixed at the end portion of the flat roof in cooperation with the waterproof layer end fixing member 1, and the finish waterproof layer 14 is fixed.
The waterproof layer end fixing member 1 is sufficient to fix the main waterproof layer at the end portion of the flat roof where the tip edge 7 is bent downward.
