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 rising part from a flat roof such as a parapet of a flat roof or a rooftop building.

[0002]

2. Description of the Related Art A waterproof structure of a flat roof has, for example, a concrete layer 32 of a flat roof 31 as shown in FIG.
A waterproof layer 33a such as asphalt is formed thereon, and a waterproof layer 33b is also provided on the inner surface of a parapet (rise wall) 34 following the waterproof layer 33a, and concrete 37 is cast on the upper surface of the waterproof layer 33a of the floor 32. In addition to forming the pressing material layer, a water-resistant panel 37 is provided on the front surface of the waterproof layer 33b, and this panel 37 blocks sunlight and the like to prevent the waterproof layer 33b from aging. JP-A-58-89516, JP-A-62-1
87121, JP-A-63-27655, etc.).

[0003]

In the above waterproof structure, the upper and lower ends of the waterproof panel 37 are supported by the rising portions 34.
The upper and lower holders 36 and 38 are used. The upper and lower ends of the panel 37 are fitted into one of the holders, and the other is screwed (Japanese Patent Laid-Open No. 63-27655).
Panel 3 with rubber stopper (Japanese Utility Model Laid-Open No. 58-89516) or mortar (FIG. 6, Japanese Utility Model Laid-Open No. 62-187121)
7 is supported.

[0004] The work of screwing and mortaring is troublesome and poor in workability. Also, rubber stoppers lack stability.

[0005] Under such circumstances, an object of the present invention is to make it easy to mount a water-resistant panel and to make the mounting state stable.

[0006]

In order to achieve the above object, according to the present invention, a waterproof layer is formed on the rising portion from the floor following the above-mentioned waterproof layer on the floor of the flat roof. A presser material layer is formed on the waterproof layer, and the surface of the rising waterproof layer is covered with a waterproof panel, and the panel holders and base holders above and below the rising section are raised from the flat roof floor supporting the upper and lower ends of the panel. The panel holder has a downward groove in which the upper end of the panel fits from below, and the base holder has an upward groove in which the lower end of the panel fits from above. The panel is supported by both holders by fitting the upper and lower ends of the panel into the groove, and the distance between the upper end of the front wall or rear wall of the upward groove and the inner upper surface of the downward groove is the vertical length of the panel. Ri is was a configuration that is longer.

In this waterproof structure, it is preferable that the lower end of the rear wall of the downward groove protrudes downward from the lower end of the front wall, and a joint is interposed between the lower part of the rising waterproof layer and the pressing material layer. Preferably, the base holder is provided.

[0008]

In the waterproof structure according to the present invention, the upper end of the waterproof panel is fitted deeply into the downward groove of the panel holder. Since the distance from the inner upper surface is longer than the vertical length of the panel, the lower edge of the panel crosses the groove front or rear wall of the base holder and reaches the groove. Is fitted into the grooves of the panel holder and the base holder and supported.

At this time, if the lower end of the rear wall of the panel holder protrudes downward from the lower end of the front wall, the upper end of the durable panel can be placed on the front surface of the protruding end and fitted into the groove.

[0010] Further, since the pressing material layer expands and contracts due to the temperature, the base holder is also moved by the expansion and contraction when the base holder is directly fixed to the pressing material layer. Therefore, before the water-resistant panel is fitted, there is a possibility that the fitting of the waterproof panel becomes difficult due to the movement of the base holder. On the other hand, after the fitting, a large load is applied to the water-resistant panel due to the movement, and the panel may be damaged. However, if the base holder is provided at the joint, the movement of the base holder in cold weather is based on the expansion and contraction of the joint, and is far less than the movement based on the amount of expansion and contraction of the presser material layer. For this reason, the above-mentioned difficulty in fitting and the possibility of panel breakage are improved.

[0011]

FIG. 1 is a partially cutaway perspective view of an example of a waterproofing portion of a parapet portion as an embodiment of a waterproof structure for a rising portion from a flat roof according to the present invention, and FIG. 1 is a flat roof, 2 is a floor made of slab concrete, 3a is a waterproof layer such as a waterproof sheet formed on the floor 2, 3b is a waterproof layer 3a on the floor 2, and It is a waterproof layer formed on the inner surface, and a panel 17 made of a water-resistant slate or the like is provided on the front surface thereof.

The upper end of the waterproof layer 3b is pressed by a panel holder 6 also serving as a presser for preventing the waterproof layer 3b from peeling off, and is fixed by an anchor bolt 7. Reference numeral 8 denotes a plug mounted on the anchor bolt 7 and having its front side expanded in concrete in all directions.

The front end of the panel holder 6 is a panel upper end holding portion 10 of a deep downward groove 9, and a rear wall 9 b protrudes downward from a front wall 9 a of the panel holder 6. The panel 17 can be smoothly inserted into the groove 9 by abutting the upper end of the panel 17 on the protruding end.

At the lower corner of the parapet 4 and at the corner of the boundary between the holding concrete 11 of the floor 2, a base holder 12 having a shallow upward groove 18 is provided with a horizontal plate portion 13 coupled from the lower side of the holder 12. The tapping screw 15 inserted into the hole 14 is screwed and fixed.

When the base holder 12 and the panel holder 6 are fixed to the parapet 4 and the floor 2, the downward grooves 9
The distance between the lower ends of the front and rear walls 9a, 9b and the inner lower surface of the upward groove 18 is shorter than the length of the panel 17 in the vertical direction, and as a result, as shown in FIG.
When the panel 17 fits into the second grooves 9 and 18, the upper end of the panel 17 is in the groove 9 and cannot be easily removed. In addition, the distance between the upper end of the front wall 18a or the rear wall 18b of the upward groove 18 and the inner upper surface of the downward groove 9 is longer than the length of the panel 17 in the vertical direction. When the panel 17 is inserted, the lower end of the panel 17 can get over the front wall 18a or the rear wall 18b of the groove 18, and when the panel 17 gets over, the panel 17 is dropped and the holders 6, 12 are lowered.
To fit.

Numeral 16 denotes a joint made of foamed polyethylene disposed at a corner, and a tapping screw 15 is screwed into the joint 16. If the concrete 11 is screwed into the joint 16 in this manner, it is not necessary to embed a plug for the screw 15 into the concrete 11 at the time of casting, and the workability is good, and the concrete 11 partitioned by the joint 16 is There is a possibility that the position of the plug 29 (FIG. 5) described later is greatly shifted due to the temperature and the temperature, and the mounting position of the base holder 12 is greatly shifted, but the position shift of the screw 15 is absorbed as much as possible by the expansion and contraction of the joint 16. Therefore, there are few such things.

Reference numerals 19 and 20 denote sealing materials provided on the upper surface of the upper end presser 21 of the rising waterproof layer 3b at the rear end of the panel holder 6 and the concave portion on the back surface.

FIGS. 3 and 4 show another example of a parapet that rises from the flat roof floor. The parapet 4a has no jaw, and a cap 22 is attached to the top.

In the case of the parapet 4a, the upper end of the rising waterproof layer 3c reaches the top of the parapet 4a, and a sealing material 23 is placed on the end. In this state, the hedder 22 and the intermediate base holder 24 and It is supported on the parapet 4a via the joint holder 27. The holder 6a that fits and supports the upper end of the water-resistant panel 17a is attached to both holders 24 and 27 with bolts 25. The joint holder 27 is provided at the joint a of the coping 22, and the required number of intermediate base holders 24 are provided at required intervals therebetween. Other components such as the base holder 12 for fitting and supporting the lower end of the water-resistant panel 17a are the same as those in FIG. In the drawing, reference numeral 26 denotes an anchor bolt for fixing the holders 24, 27.

As shown in FIG. 5, the base holder 12 can be attached to the concrete 11 via anchor bolts 28 and embedded plugs 29.

[0021]

According to the present invention, as described above, the rising portion from the flat roof can be waterproofed with a smooth operation, and the mounting stability of the waterproof panel is good.

If the rear wall of the groove of the upper end holder of the waterproof panel is made longer than the front wall, the upper end of the panel can be easily fitted into the groove. Also, if you provide a base holder at the joint,
The displacement of the holder due to the expansion and contraction of the holding material layer can be reduced as much as possible, and the risk of the panel coming off the holder is also reduced.
