[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shed mounting member used for waterproofing a parapet portion of a flat roof and a waterproof structure of the parapet portion.

[0002]

2. Description of the Related Art As a waterproof structure of the above parapet, the present applicant has disclosed Japanese Patent Application No. 63-73636 (Japanese Patent Application Laid-Open No. 1-2105).
No. 62) proposed one technique. The technical content is
As shown in FIG. 6, a water-resistant board 2 is provided along the inner side surface of the parapet 1 with a flat roof, and a capping member 7 is screwed on the upper surface of the parapet 1, and the holder 3 is screwed to the capping member 7. Then, the upper end of the water-resistant board 2 is supported by the holder 3, and the lower end is supported by the lower holder 5 fixed to the holding concrete 4, so that the coping 8 is mounted on the coping mounting member 7. In the figure, 9 is a waterproof sheet, and 10 is a sealing material at the edge.

[0003]

[Problems to be solved by the invention] In the above technology,
Since the attachment member 7 is attached to the parapet 1 with one screw 6, the attachment is unstable, and when a large force is applied to the attachment member 7 when attaching the water-resistant board 2, the attachment member 7 moves. And inconveniences such as floating.

In order to increase the mounting strength, mounting with a plurality of screws may be considered.
In order to arrange a plurality of screws in the width direction of the parapet 1, the screw holes are small, and if the screw positions are too close, the parapet 1 may be cracked. For this reason, despite the above-mentioned inconvenience, the screw has been attached by tightening one screw 6.

[0005] It is an object of the present invention to increase the mounting strength of a capping member without deteriorating workability.

[0006]

In order to solve the above-mentioned problem, according to one aspect of the present invention, a mounting member 17 screwed to the parapet 1 is used to mount the coping 8 on the upper surface of the parapet 1 on a flat roof. Therefore, the following points are adopted.

The attachment member 17 includes an upper surface cover 17a that covers the upper surface of the parapet 1, and an outer end bent portion 17b and an inner end bent portion 17b ′ in which the outer and inner ends of the upper cover 17a are bent downward. .

[0010] A mounting recess 18 is provided in the upper surface cover 17a.

Two mounting holes 19 a and 19 b which are long in the width direction of the parapet 1 are formed in the mounting recess 18 sequentially in the width direction, and one mounting hole 19 a is longer than the other mounting hole 19 b.

In a second aspect of the present invention, the waterproof structure of the parapet portion of the above-mentioned flat roof has the following configuration.

[0011] Mounting holes 19a and 19b which are long in the width direction of the parapet 1 are formed in the cap mounting member 17, and one of the mounting holes 19a and 19b is formed.
The attachment hole 19a is made longer than the other attachment hole 19b.

The mounting member 17 is attached to the mounting hole 1.
A plurality of screws 20a, 20b inserted through 9a, 19b are screwed to the upper surface of the parapet 1.

The holder 13 is attached to the mounting hole 19 a
The screw 14 is screwed to the coping attachment member 17 by another screw 14 that has been inserted.

[0014]

In each of the first and second inventions, the mounting holes 19a and 19b which are long in the width direction of the parapet 1 are provided.
A plurality of screws 20a and 20b are inserted into the capping member 17 to fix the capping member 17 to the upper surface of the parapet 1, and the screwing position is freely selected within the range of the mounting holes 19a and 19b.

In the case of the second invention, screwing of the water-resistant board upper holder 13 is also performed using the mounting hole 19b, and the screwing position can be freely set within the range of the mounting hole 19b as described above. Select.

[0016]

[Effect] The present invention has the following effects because of the above-described configuration.

[0017] The capping member 17 is provided by a plurality of screws.
Can be fixed to the parapet 1, so that its mounting stability is good.

The screw fixing positions are the mounting holes 19a, 1
Since it is free within the range of 9b, even if the width of the upper surface of the parapet is not uniform, it is possible to sufficiently secure the screwing position inside the required length from the edge thereof, and there is no possibility that the edge of the parapet 1 is chipped.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a waterproof sheet 9 is laid from the slab concrete C on the flat roof on the inner surface of the parapet 1 to the upper surface of the parapet 1, and the edge of the waterproof sheet 9 is placed on the outer side of the upper surface of the parapet 1. It is sealed by the sealing material 10 along the edge.

3 and 4 are screwed to the upper surface of the parapet 1 at required intervals. The mounting member 17 is a molded product of plastics, metal, etc.
The parapet 1 includes an upper surface cover portion 17a covering the entire width, and bent portions 17b and 17b 'having both ends bent downward.

The upper cover 17a is provided with recesses 18 and 18, and the recesses 18 and 18 have elongated holes (mounting holes) 19, respectively.
a, 19b are formed, and the inner edge of the recess 18 in FIG. 3 is a gap 18a, 18b.

The slots 19a and 19b are provided in the parapet 1
The inside 19a of the upper surface is longer than the outside 19b. By extending the length in this manner, as shown in FIG. 2, the mounting positions of the mounting screws 20 a of the capping member 17 to the parapet 1 and the mounting screws (bolts) 14 of the water-resistant board holder 13 to be described later are moved. Becomes large, and the mounting position of the screw 20a is too close to the end of the parapet 1, so that the parapet 1 does not crack.

The long holes 19a of the screws 20a and 14 are used.
May be divided into two. That is, long holes for inserting both screws 20a and 14 may be formed.

The attachment member 17 shown in FIG. 3 is installed at the seam of the coping 8 and the one shown in FIG. 4 is installed at an intermediate portion of the coping 8 (see FIG. 1).
Are formed, and the water from the joint flows between the ribs 21 to obtain a complete waterproof effect.

The upper holder 13 of the water-resistant board 2 is screwed to the inner surface of the inner end of each mounting member 17. The upper holder 13 having a required length of the cross-sectional shape shown in FIG. 5 is provided continuously over the entire length of the parapet 1, and the screw 14 is inserted into the groove 13a to be moved, whereby the mounting member 17 is moved.
Corresponding to the long hole 19a. A cushion material 15a is fitted and adhered to the inner surface of the outer wall of the upper holder 13.

The lower end of the water-resistant board 2 is supported on the holding concrete 4 by a lower holder 16 with screws. As shown in FIG. 2, the lower holder 16 is composed of a pair of divided parts 16a and 16b, one of which is screwed to the holding concrete layer 4 and one of which is fixed to the other one 16a.
6b is fitted in the horizontal direction, and the upright U-shaped section 16c is formed by the upright walls of both. One split part 16
A cushion 15b is fitted to the vertical wall of the area "a".

The upper end of the water-resistant board 2 is placed on the upper holder 1 with the other divided part 16b of the lower holder 16 removed.
3 and the lower end thereof is applied to one of the divided parts 16a of the lower holder 16, and then the other divided part 16b is fitted to the one of the divided parts 16a to be attached.
