Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a flat roof of a building, and particularly to a structure for treating the ends of a waterproof sheet at the rising portion of a parapet.

[Conventional technology and its problems]

When attaching a waterproof sheet to a flat roof, if you use the floating method, which allows the sheet to be applied even when the base is wet, without waiting for the base to dry, it will allow water vapor and thermally expanded air generated from the base to escape. , a complicated process such as providing an exhaust pipe is required.

Therefore, the technical problem of this invention is to provide a flat roof structure that has a simple structure, allows water vapor and air to escape along the parapet, and prevents rainwater from entering.

[Means to solve the problem]

In order to solve the above-mentioned problems, this invention was developed by floating a waterproof sheet on the flat end of a flat roof with a parapet, and attaching the end of the waterproof sheet along the inside surface of the parapet. The end treatment tool of the waterproof sheet attached to the upper corner of the inner surface is made of a vertical plate part along the inner surface of the parapet, an inclined plate part that bends inward from the vertical plate part and slopes downward, and the inclined plate part. It has a rising part that bends upward from the tip of the plate part and contacts the lower surface of the eaves edge of the parapet,
A deaeration hole was provided in the inclined plate part, the vertical plate part of the terminal treatment tool was nailed to the inner surface of the parapet, and the end of the waterproof sheet was affixed to the surface of the vertical plate part. It is something.

[Effect]

Water vapor and thermally expanded air generated from the base of the floating waterproof sheet pass through the inner surface of the waterproof sheet along the parapet, pass through the inside of the vertical plate of the nailed end treatment tool, and reach the eave edge at the upper end of the parapet. It escapes below and is discharged to the outside through the degassing hole in the inclined plate part.

Even if rainwater blows in through the deaeration hole of the inclined plate part, the rainwater moves to the lower slope of the inclined plate part and is prevented from going around to the back side of the vertical plate part.

〔Example〕

In the figure, 1 is the flat part of the flat roof of the building, 2
are the parapets erected around it. The parapet 2 has an eave edge 4 formed at the upper end of its inner surface.

A waterproof sheet 3 is pasted on the flat area 1 of the flat roof using the floating pasting method, and its terminal is attached to the parapet 2.
It rises along the inner surface of the

The end treatment tool A of the waterproof sheet 3 is long and has a vertical plate part 5 that runs along the inner surface of the parapet 2, and an inclined plate part 6 that is bent inward and inclined downward at the upper end thereof. is formed, and a standing plate part 7, an inwardly bent plate part 8, and a small standing plate part 9 are bent at the tip of the inclined plate part 6, and a deaeration hole 10 is provided in the inclined plate part 6. It is being

The terminal processing tool A described above has the small upright plate part 9 applied to the lower surface of the eaves edge 4, and the vertical plate part 5 attached to the nail 11.
It is fixed to the inner surface of the parapet 2. Caulking material 1 is applied to the corner parts of the small upright plate part 9 and the plate part 8.
2 is filled to ensure watertightness. Since the vertical plate part 5 is simply fixed to the inner surface of the parapet 2 with nails 11, there is a gap between the vertical plate part 5 and the inner surface of the parapet 2 through which air can circulate.

The end of the waterproof sheet 3 is attached to the inner surface of the vertical plate portion 5.

In the flat roof of the above structure, water vapor and thermally expanded air generated on the lower surface of the waterproof sheet 3 pass through the gap between the parapet 2 and the waterproof sheet 3, and further through the gap between the inner surface of the vertical plate portion 5 and the parapet 2. It passes through to the corner of the eaves edge 4, and is discharged to the outside through the degassing hole 10 of the inclined plate part 6.

Moreover, when rainwater blows in from the deaeration hole 10, the rainwater moves downward along the slope of the inclined plate part 6, so that it can be prevented from going around to the back side of the vertical plate part 5.

[Effect of idea]

As described above, this invention is based on the fact that the ends of the tarpaulin sheet are attached to the end treatment tool nailed to the inner surface of the parapet, and by providing deaeration holes in the inclined plate part of the end treatment tool, the lower part of the waterproof sheet It is possible to remove water vapor and thermally expanded air. In addition, since the above-mentioned inclined plate part is inclined so that the inside becomes lower (that is, it becomes lower as it moves away from the parapet), even if rainwater blows in from the ventilation hole, the rainwater will flow downward along the slope. Therefore, it is possible to avoid going around to the back side of the vertical plate part and entering the inside of the waterproof sheet.
