Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure for a parapet roof (a protective wall top surface) such as a roof of a building or a balcony.

[0002]

2. Description of the Related Art Parapets such as roofs of concrete buildings and balconies are directly exposed to rainwater, and are therefore waterproofed. This waterproof structure is formed by extending a waterproof material laid on the floor surface to the parapet roof, and the roof is covered with a head tree or an angle cover.

That is, as shown in FIGS. 3 and 4, a waterproof layer 4 is laid extending from the floor surface 1 of a rooftop or a balcony to the ceiling 3 through the inner surface of a parapet (protection wall) 2.
Further, in order to prevent rainwater from penetrating from the end of the waterproof layer 4, a caulking material 5 may be applied between the top part 3 and the end of the waterproof layer 4, and a casket 6 or an angle cover 7 may cover it. .

In FIG. 3 (A), a headboard 6 is fixed to the ceiling 3 of the parapet 2 at a predetermined interval in the longitudinal direction by fixing mounting brackets 8 with anchor bolts 9, and an aluminum plate or the like is mounted on the mounting bracket 8. A cap tree 6 having a substantially U-shaped cross-section is crowned, and both end portions 6a thereof are bent inward and locked to the force plate portion 8a of the mounting member 8 so as to be fixed.

As shown in FIG. 3 (B), a corner cover 10 for covering the corner of the roof 3 is used as the corner of the head cover 6, and the corner cover 10 is welded beforehand in a factory. It is manufactured and is connected on the site with the joint 11 having a U-shaped cross section and the mounting member 8 between the end of the headboard 6 and the end.

Further, in FIG. 4A, the angle cover 7 has an L-shaped cross section having a width of about half of the head tree 6, and the angle cover 7 is provided on the ceiling 3 in the longitudinal direction in a waterproof layer. 4, the skirt portion 7a is hung from the ceiling 3 and placed, and the anchor bolt 12 is directly driven and fixed onto the parapet 2 from above the ceiling cover portion 7b. A caulking material 13 is filled and sealed between the head of the anchor bolt 12 and the angle cover 7, and between the end of the top cover 7b and the waterproof layer 4.

Further, as shown in FIG. 4B, the corner portion of the angle cover 7 in this example is obtained by cutting the end portion of the angle cover 7 at 45 degrees and abutting it, and applying the caulking material 13a. There is.

[0008]

However, in the above-mentioned conventional headboard 6, the headboard 6 needs various types according to the width W of the top 3 and the width W of the top 3 is higher than those of the various types. If it is too large, it becomes a custom-made product, which has the drawback of increasing the cost.

Further, in the conventional angle cover 7,
Due to the difference in thermal expansion and contraction rates between the waterproof layer 4 and the angle cover 7, the angle cover 7 and the waterproof layer 4 made of aluminum material.
Since the caulking material 13 is cut off as a result of a foreign substance competing with the above, the utility of the seal is lost.

Further, since the angle covers 7 at the corners are not welded, the caulking material 13a is made up of the same aluminum material, which causes a problem.
Since the utility of the seal is lost, there is a drawback that it lacks durability.

[0011] Therefore, an object of the present invention is to provide a waterproof structure for a parapet roof that is simple, quick, easy and inexpensive to construct and has high durability.

[0012]

According to the waterproof structure for parapet heaven of the present invention, a waterproof layer laid on the roof of a building or on a floor of a veranda or the like is extended to the parapet heaven, and an end portion of the waterproof layer is provided. In a waterproof structure for parapet heaven covered with a cover, the cover has a top cover whose cross-sectional shape is smaller than the width of the parapet heaven, and a skirt hanging on the outer surface of the parapet heaven. A substantially L-shaped angle member having a mounting member for fixing the cover to the parapet ceiling at predetermined intervals, and an inner end side of the mounting member for covering the top surface of the cover. Fixing a corner joint with a packing interposed between the waterproof layer and a fitting part for mounting the cover on the corner part of the parapet top, which is substantially L-shaped in plan view. , Butt cutting the cover to 45 degrees on the corner joint, and wherein the forming a stop cutting.

[0013]

[Function] Since the cover and the mounting bracket need only have a width smaller than the width of the parapet roof, the construction can be performed inexpensively regardless of the width of the parapet roof. Also, since the corner joint is used, the cover can be cut off.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1 (A), mounting brackets 14 are anchored to the anchor bolts 15 at predetermined intervals in the longitudinal direction on the waterproof layer 4 extending and laid on the ceiling 3 of the parapet 2 and provided with the caulking material 5. Then, an angle cover 16 having an L-shaped cross section is attached to these mounting brackets 14.

The mounting bracket 14 is formed by bending a plate body having a predetermined width. The force plate portion 17 on one end side hangs down on the outer surface of the parapet 2, and the force plate portion 18 on the other end side. The waterproof layer 4 is inclined upward in the vicinity of the middle in the width direction. Therefore, the mounting bracket 14 is smaller in shape than the conventional mounting bracket 8.

The angle cover 16 is formed by bending a plate body into an L-shaped cross section, and is provided on the top 3 of the parapet 2.
An angle member having an L-shaped cross section having a top surface covering portion 16a having a width w smaller than the width W and a skirt portion 16b hanging on the outer surface of the parapet 2. The lower end of the skirt portion 16b is bent and locked to the force plate portion 17 of the mounting member 14, and the locking piece 19 fixed to the top cover portion 16a by welding or the like is engaged with the force plate portion 18 of the mounting member 14. It has stopped. A packing 20 is interposed between the waterproof layer 4 and the end portion of the top cover 16a of the cover 16. The packing 20 is a long member having a rectangular cross section, but may have a circular cross section.

Further, as shown in FIG. 1B, the corner portion of the angle cover 16 has a corner joint 22 fixed to the top 3 of the parapet 2 with anchor bolts 21.
Placed on. A joint 23 is used to connect the angle covers 16 to each other, like the joint 11 of the conventional example.

As shown in FIG. 2, the corner joint 22 has substantially the same shape as that of the fitting 14 and has a force plate portion 2 for locking the lower end portion of the skirt portion 16b of the angle cover 16.
Between the mounting bracket portion 25 having the reference numeral 4 and the substantially triangular flat plate portion 26 which is integrally connected to the mounting bracket portion 25 and placed on the waterproof layer 4, and between the flat plate portion 26 and the mounting bracket portion 25. End formed by cutting the flat plate portion 26 at 45 degrees, which is a pair of a partition plate 27 fixed to the flat plate portion 26 and a skirt portion 28 formed on the flat plate portion 26 continuously with the force plate portion 24. The parts 29 are butted and welded together.

The mounting bracket 25 has an anchor bolt 21
Is formed with a through hole 30, and a force plate portion 31 for locking the top cover portion 16a of the cover 16 is formed.
The flat plate portions 26, 26 are inclined toward the sides facing each other and end portions 2
9 may be butt-welded, or the flat portion 2
The end portions 29 may be welded so that 6, 26 are flush with each other.

[0020]

According to the present invention described above, since the end portion of the waterproof layer laid on the parapet top is covered with the cover through the mounting metal fitting, the width of the cover can be small. Also, since the mounting bracket can be downsized, it can be constructed at low cost regardless of the width of the parapet roof.

Further, the cover at the corner portion of the parapet roof can be fixed by abutting the ends cut at 45 degrees to the corner joints, stopping without welding, and without needing to apply caulking material. The work of closing corners is simple, quick and easy.
