いた。(Prior art and its problems) After exposed waterproofing construction, even if the moisture in the base evaporates to the surface due to thermal expansion caused by sunlight, the waterproof layer swells because there is no vent to let it escape. It turns out. Conventionally, appropriate locations in the waterproof layer are hollowed out to provide deaeration ports to allow water vapor to escape, and deaeration panels are installed here to block rainwater from entering. The deaerator referred to here refers to Utility Application No. 55-31656 (Utility Application No. 31656) filed by the same person as the applicant.
56-133031), it is made of a porous material that allows water vapor to pass through when a pressure above a certain level is applied, but completely blocks water from entering under normal pressure. However, the gap created at the joint between the deaeration port of the waterproof layer and the deaeration plate is likely to cause additional rainwater to enter. Regarding this point, according to the prior art, for example, in the case of sheet waterproofing, a deaeration plate is placed over the edge of a deaeration port cut out of the waterproof sheet,
The deaeration plate is directly fixed to the substrate using rivets or other means,
Furthermore, a caulking agent was applied to the joint between the deaerator and the waterproof sheet to fill the gap. Another method is to place a deaeration plate on top of the edge of the deaeration port cut out of the tarpaulin sheet, and then prepare another small piece of tarpaulin sheet (approximately 50 cm 2 to 70 cm 2 ). The central part is hollowed out to approximately the same size as the deaeration port of the above-mentioned tarpaulin sheet, and a deaeration port is also provided therein, and this small piece of waterproof sheet is superimposed on the deaeration board so that the deaeration board is visible in the deaeration port, Next, apply caulking agent to the joint between the deaeration port edge of this small piece of waterproof sheet and the deaeration panel, and the joint between the outer edge of the small piece of waterproof sheet and the waterproof sheet stretched on the surface of the base. Fixing small pieces of tarpaulin was also practiced.

題もあつた。 However, in any of the above conventional methods, since the joint between the deaerator and the waterproof sheet is a surface joint, it is unavoidable that the pressure is weakened, and the caulking agent applied to the gap between the two is unavoidable. Since it is directly exposed to the surface, there is a risk that the coating film will be abraded by shoes or the like walking over the caulking agent-coated surface, and the edges of the tarpaulin sheet may be turned up. Furthermore, when retightening butyl-based sheets, which are commonly used as waterproof sheets, it is customary to leave an overlapping area of about 10 cm to prevent rainwater from entering. is welded, so it is customary to have a width of about 5 cm at the overlapping part of the extension, although it is said that a narrow width is sufficient. From the viewpoint of preventing rainwater from entering, it is also required that the joints with the waterproof sheet have the same width.
However, in order to obtain such a wide overlapping area, the degassing disk itself had to be increased in size, which caused various problems. In other words, because the material of the deaerator is porous and needs to be formed into a thin plate, it is technically difficult to make it larger, and the material costs and transportation costs associated with larger sizes are also higher. There were also economic problems.

としての機能は全く損われることがない。 First, as described above, the waterproof sheet 4, caulking agent 7, deaeration plate 2, small pieces of waterproof sheet 8, and seat rubber 10 are placed on top of the base 3, and then the presser metal fitting 1 is placed.
The center hole 12 and the center hole of the deaeration plate 2 are aligned, and the screw 16 is inserted into the center hole 12 of the holding fitting 1.
Pass through the hole in the center of the seat rubber 10 and the hole in the center of the deaeration plate 2 and screw into the claw plug 6 embedded in the base surface, tighten all of the above-mentioned members together, and place the screw on the base surface. Fix it. Since the cover part 13 of the presser metal fitting 1 is supported by the warping of the peripheral edge part 11 and is in a state of floating above the exposed surface of the deaeration plate 2, it prevents water vapor in the base 3 and the lower surface of the waterproof sheet 4, that is, the waterproof layer. The water vapor inside can pass through the deaeration plate 2 and rise to the upper surface, and can evaporate through the opening 14 formed in the cover part 13, so the function as a deaeration plate is not impaired at all. .

つ、経済的にも低廉になるという効果がある。(Effects of the present invention) Since this invention consists of the above-mentioned configuration, it has the effect that the deaeration plate can be fixed to the substrate surface much more reliably than in the conventional state without a holding metal fitting. First of all, there is. In other words, without the presser fitting of the present invention, the edge of the deaeration port of the tarpaulin was simply held down by the periphery of the deaeration plate by the screw screwed into the claw plug. The joining mode of the boards is surface joining, and
Since the deaeration plate was held down only at one central point, the pressing force was dispersed and weak, and strong tightening of the screws could damage the center hole of the deaeration plate. However, in the presser metal fitting of the present invention, the curved peripheral edge comes into contact with the small piece of waterproof sheet placed on the top surface of the deaeration plate, and the deaeration plate is held down by the interaction of the claw plug and the screw. If the deaeration plate is not used, the deaeration plate is held directly at the peripheral edge, so in any case, the joining mode is a line joint, and the holding of the deaeration plate is distributed only from the center point to the line joint. The pressing force is significantly stronger than when it is distributed from the surface to the surface joint, and on the other hand, the force is reliably distributed, so even if the screws are strongly tightened, there is no risk of damaging the center hole of the degassing disk. Furthermore, since the joint is a line joint, the deaeration plate can be significantly downsized, and as a result, the technical difficulties in manufacturing the deaeration plate described above can be easily eliminated, and it is also economically inexpensive. There is an effect.
