Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof sheet formed of a flexible synthetic resin material on a roof surface. A snow stopper that has a locking surface portion that can be locked against snow on the surface and that prevents the snow from falling from the roof is fixed by a fixture that can penetrate and fix the structure below the roof surface. And a sheet-covered roof having a snow stopper formed thereon.

[0002]

2. Description of the Related Art In the above-mentioned conventional sheet-covered roof,
For example, as shown in FIG. 9, a fixing portion 6 of a snow stopper 4 for forming a snow stopper 3 is provided on a waterproof sheet 2 laid on a roof surface 1 of the structure 10. Is fixed to the structure 10 with a fixture 7 which can penetrate freely.
Generally, a fixing anchor 8 is used as the fixing tool 7. This sheet-covered roof is formed, for example, as follows. As shown in FIG. 10, a waterproof sheet 2 is spread over a structure 10 of a concrete roof that forms a concrete field, and a roof surface 1 is formed. On the roof surface 1, the snow stopper 4 is placed in alignment with an anchor hole drilled in the structure 10, and the anchor bush 8 of the fixing anchor 8 is passed through the screw hole 6a.
a is inserted into the anchor hole by passing through the anchor hole 2b formed in the waterproof sheet 2 and aligned with the anchor hole. Then, the anchor pin 8b is driven into the anchor bush 8a, and the anchor bush 8a is driven.
And is fixed to the structure 10. Thereafter, for waterproofing, the head of the anchor pin 8b, the anchor bush 8a, the screw hole 6a of the snow stopper 4 and its surroundings are
Sealing is performed using a caulking material S.
Similarly, the peripheral portion of the snow stopper 4 may be similarly sealed with the waterproof sheet 2 with a caulking material S as necessary.

[0003]

In the case of a sheet-covered roof in which the snow stopper 4 is attached from above the waterproof sheet 2 as in the prior art, if there is snow, slippage from the waterproof sheet 2 occurs. Due to the weight of the falling snow, an external force that pulls down the waterproof sheet 2 toward the eaves acts on the waterproof sheet 2. Due to the action of this external force, a part of the waterproof sheet 2 may try to move to the eaves side along the roof surface. However, since the fixing anchor 8 for fixing the snow stopper 4 penetrates and is fixed to the structure 10 below the waterproof sheet 2, the waterproof sheet 2 is fixed.
When the snow stopper member 4 is stopped from above, the anchor holes 2b for the anchors 8 are relatively pulled up toward the ridge side by the anchors 8 and the holes 2b of the anchors 2b are removed. The periphery may crack and break the waterproof sheet 2 to induce water leakage. When the waterproof sheet 2 attempts to move relatively to the eaves side with respect to the fixed snow stopper member 4 and the relative movement between the waterproof sheet 2 and the snow stopper member 4 occurs, the snow stopper Even if the peripheral portion of the member 4 is sealed with the caulking material S, the caulking material S peels off. If the caulking material S peels off, the peripheral portion of the snow stopper 4 is not sealed. There is a possibility that the water will be sufficient, and the thaw water will enter the lower side of the snow stopper 4, causing water leakage from the anchor hole 2 b of the waterproof sheet 2. Further, since the caulking material S is not a permanent sealing material, it requires regular maintenance. As described above, the sheet-covered roof to which the snow stopper 4 is attached from above the waterproof sheet 2 as in the related art has a problem in waterproof performance.

Therefore, the sheet-covered roof according to the present invention is:
An object of the present invention is to make it possible to easily form a snow stopper and not to deteriorate its waterproof performance.

[0005]

[First aspect of the present invention] The first aspect of the sheet-covered roof according to the present invention is as follows.

It is arranged so as to cover the peripheral portion of the member, and the peripheral portion of the waterproof covering material is water-tightly bonded to the waterproof sheet at least on the ridge side from the eaves end of the area. In addition, as described in claim 2, the waterproof covering material in the first characteristic configuration is covered over the entire snow stopper, and the peripheral edge of the waterproof covering material is thermally fused to the waterproof sheet over the entire circumference. (The second characteristic configuration).

According to the first feature of the sheet-covered roof according to the present invention, water leakage from the roof surface can be reliably prevented while the snow stopper is mounted on the waterproof sheet. it can. In other words, while the snow stopper is mounted on the waterproof sheet, at least a region from the locking surface of the snow stopper which can be locked to the snow cover to the fixing portion by the fixture covers the peripheral edge of the snow stopper. As described above, covering with a waterproof covering material, from the area to the ridge side end of the waterproof covering material, the waterproof covering material is bonded to the waterproof sheet in a water-tight manner, so that the slope of the roof surface is used, It becomes possible to prevent snow melt water from reaching the snow stopper. Therefore, even if the underside of the waterproof covering material is wet, it is possible to prevent snowmelt from reaching the fixing portion and prevent water from leaking to the back side of the waterproof sheet. In addition, according to the said 2nd characteristic structure, since the said snow stopper does not contact snowmelt, water leakage can be prevented reliably.
