Description of the Related Art As a waterproofing mechanism for a flat roof of a concrete building, an insulating sheet for heat insulation is laid on the flat roof, and a large number of waterproof sheets are laid side by side, and the edges of two adjacent waterproof sheets are laid. A method of double-covering a flat roof with an insulating sheet and a waterproof sheet by overlapping and bonding is known.However, in order to prevent the displacement by fixing the above-mentioned waterproof sheet to the flat roof, conventionally, the above-described insulating sheet is used. A band-shaped holding plate was previously placed on the sheet at a predetermined interval and fixed to a flat roof with screws or bolts, and the edge of the waterproof sheet was bonded to the band-shaped holding plate. Further, a large number of iron disks are arranged side by side at predetermined intervals on a waterproof sheet, and screws or bolts are inserted from above the disks and fixed to a flat roof.

When a strong wind such as a typhoon blows and a negative pressure acts on the waterproof sheet, the parts other than the adhesive part of the waterproof sheet float up, and especially at places near the parapet, the negative pressure increases and the adhesive fixing part may peel off. there were. In addition, when driving screws from an iron disk arranged on the waterproof sheet, the screw driving interval can be set arbitrarily, but if the driving interval is widened, the waterproof sheet may rise due to strong wind and peel off as described above. When the driving interval is reduced, there is a problem that the construction becomes troublesome and the number of steps increases.

For example, a basis weight of 200 to 1000 g / m made of synthetic fiber
A felt-like nonwoven fabric of 2 is preferred. This basis weight is 200
no effect to equalize the pressure of the upper and lower surfaces of the waterproof sheet is less than g / m 2, workability exceeds 1000 g / m 2 is considerably deteriorated opposite. On the other hand, the waterproof sheet is the same as the conventional one, and includes a resin sheet made of polyvinyl chloride or other synthetic resin, a rubber sheet made of rubber such as natural rubber and synthetic rubber, and a fiber sheet made of woven or knitted fabric. And the like.

For example, after laying an insulating sheet, arranging strip-shaped holding plates on it at a pitch equal to the width of the waterproof sheet,
Fix it with screws, overlap the edges of the two waterproof sheets on this band-shaped holding plate, fix the lower waterproof sheet to the band-shaped holding plate with adhesive or welding, and glue the waterproof sheets together at the edges. Join. In addition, the waterproof sheet is arranged directly on the insulating sheet, and the two edges are joined by bonding, and the band-shaped pressing plate or the disc placed on an arbitrary position is fixed on the flat roof with screws. You can also. If you are repairing a flat roof that has been waterproofed with an asphalt layer impregnated with felt,
The above-mentioned insulating sheet can be laid directly after or without peeling the asphalt layer.

This ventilation pipe fills the space below the waterproof sheet, that is, the internal space of the insulating sheet. The waterproof sheet is made to communicate with the outside air so that the inside and outside air pressures of the waterproof sheet are always equalized, and can be erected in any form as long as the lower end of the ventilation tube communicates with the internal space of the insulating sheet. For example, a flange may be provided at the lower end of the ventilation tube, the flange may be placed on an insulating sheet, and fixed to the concrete layer of the flat roof with a plurality of screws or anchor bolts. Then, the back surface of the edge of the ventilation window opened in the waterproof sheet is fixed on the flange by bonding, and the edge of the ventilation window is sealed with the ventilation tube. Further, as the floating roof attached to the upper end of the ventilation tube, any floating roof can be used as long as it prevents wind and rain from being blown into the ventilation tube. The ventilation tube is preferably a cylinder having an inner diameter of about 30 to 300 mm. If the diameter is less than 30 mm, there is no effect. On the other hand, if it exceeds 300 mm, it is too large to be transported or mounted. In addition, the height is preferably 50 to 500 mm, and if it is lower than 50 mm, there is a danger that rainwater will enter the inside from the edge of the ventilation tube,
Conversely, if it is higher than 500 mm, it tends to be an obstacle.

能が低下することがない。In the above waterproof mechanism, since the space above the waterproof sheet and the air layer in the lower insulating sheet communicate with each other through the ventilation tube, the air pressures of both become equal. That is, when a strong wind such as a typhoon blows and the space above the waterproof sheet becomes a negative pressure, the air in the lower insulating sheet is sucked out to the outside through the ventilation tube, and the lower side of the waterproof sheet is also reduced in pressure. Therefore, the waterproof sheet does not rise. Also,
Since the ventilation window of the waterproof sheet is sealed with the ventilation tube and the floating roof is attached to the ventilation tube, the waterproof performance of the waterproof sheet does not decrease.
