Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a waterproof structure of a rising portion from a flat roof floor such as a parapet or a rooftop tower, its panel holder, its bracket, its cover plate, and its base holder. It is a thing.

[Conventional technology]

As shown in FIG. 6, the conventional waterproof structure for a flat roof is such that a waterproof layer 43a such as asphalt is formed on the floor concrete layer 42 of the flat roof 41 and the waterproof layer 43a is formed.
Following a, a waterproof layer 43b is also formed on the inner side surface of the parapet 44, the upper end of which is stopped by a presser member 46, and concrete 47 is placed on the upper surface of the waterproof layer 43a.
On the front side (front surface) of 3b, bricks 49 are piled up while mortar 48 is piled up, and a light shielding protective layer of both waterproof layers 43a and 43b is formed by the stacking and the concrete 47, and the weather resistance of the waterproof layers 43a and 43b. To prevent the decline of.

Although not shown, a waterproof layer is also formed on the outer surface of the rising wall of the rooftop tower.

[Problems to be solved by the device]

However, the brick-laying method for forming the light-shielding protective layer is a troublesome work, and since it is a wet method, there is a problem that it takes time and labor to extend the construction period.

Therefore, the present invention has devised a waterproof structure shown in FIG.
That is, similarly to the above, on the inner surface of the parapet 51,
Waterproof layer 53a on slab concrete 52 on flat roof floor
Then, a waterproof layer 53b which rises up is formed, and the upper end of the waterproof layer 53b is fixed by a presser piece 54.

On the outer surface side of the waterproof layer 53b, in order to prevent the weather resistance of the waterproof layer 53b from being deteriorated, a panel 55 such as a water resistant straight line or a metal plate covering the waterproof layer 53b has its upper end placed on the presser foot 54. The panel 55 is supported by an integral panel holder 56, and the lower end of the panel 55 is supported by a base holder 57.

There is a possibility that unevenness may appear in the length direction without following the. If there are irregularities, the panel 55 cannot be fitted smoothly.

Further, even in the case of the heat insulating method in which the heat insulating material is interposed inside the water resistant panel 55, the heat insulating material is limited by the width of the panel holder 56 and only a certain thickness can be used.

On the other hand, the upper holding portion of the panel 55 of the panel holder 56 makes the groove extremely deep and holds the panel by repulsive elasticity, but the holding portion of the lower end of the panel 55 of the base holder 56 has a shallow groove portion to prevent water resistance. While the upper end of the panel 55 is tilted forward, the panel 55 is inserted deeply into the panel holding portion of the panel holder 56, and then the panel 55 is returned vertically to be attached to the panel holding portion of the base holder 56. The panel holding portion of the holder 56 needs to have a groove width corresponding to the thickness of the panel 55 to be used so that the lower side of the supported panel 55 does not rattle, and a plurality of types of base holders having different groove widths are provided. Must be in stock.

Further, when the base holder 56 is fixed to the joints of the entering corners with the tapping screws, if the joints are made of an elastic material such as foamed polyethylene, the tapping screws may be slanted, which is not preferable.

This device is intended to solve the above problems,
One of its purposes is a waterproof structure that can support a water-resistant panel in conformity with the unevenness of the rising portion from the floor, and that allows a heat insulating material of various thickness to be interposed between the rising waterproof layer and the water-resistant panel. Another purpose of the panel lower end is to allow the lower end holding portion of the panel to hold the lower end of the panel without rattling, regardless of the thickness of the waterproof panel used.
