、持ち運びや施工に便利である。As described above, the ventilation louver 3 can be reliably and easily placed at a predetermined position in the ventilation hole 2 because its peripheral piece is buried in the concrete foundation 1 and fixedly placed in the ventilation hole 2 when concrete is poured. Moreover, it will not come off inadvertently from the ventilation hole 2. Furthermore, since the finishing mortar 30 is not applied higher than the lower surface 6 of the ventilation hole 2 on the indoor side,
The finishing mortar 30 does not dam up rainwater etc. that have entered the indoor side of the ventilation louver 3. Furthermore, since the formworks 10a and 10b for both ventilation holes forming the foundation ventilation hole are the same, mass production is possible and costs can be reduced. There is no need to distinguish between outdoor use and indoor use, making it convenient to carry and install.

に起因する換気ガラリの腐食等を防ぐことができる。(Effects of the Invention) As described above, according to the method for attaching a ventilation louver in a foundation ventilation hole according to the present invention, in the clamping portion of the formwork for both ventilation holes that clamps the lower edge piece of the ventilation louver, the The clamping part of the formwork for the outside ventilation hole is stepped so that it protrudes lower than the gripping part of the formwork for the indoor ventilation hole, so the foundation ventilation hole formed by this is placed under the ventilation louver. On the lower surface where the edge piece is embedded and fixed, a step is created where the lower surface on the outdoor side is lower than the lower surface on the indoor side. Therefore, even if finish mortar is applied to the lower surface of the outdoor side, if the thickness of the finished mortar is made smaller than the step difference, the finished mortar will not be higher than the lower surface of the indoor side. Therefore, rainwater, etc. that has entered the indoor side of the foundation ventilation hole flows out to the outdoor side without being blocked by the finishing mortar. Therefore, rainwater or the like does not accumulate on the indoor side of the ventilation hole, and corrosion of the ventilation louver caused by this can be prevented.
