れるようになっている。A bolt (6) is screwed into the female screw hole of the cylindrical main piece (3a) of the ventilation pipe (3) from the lower end of the main piece (3a), and the bolt (6) connects the ventilation pipe (3). It is designed to be opened and closed.
而してコンクリートの養生不足が予想される防水工事等
においては、前記通気管（３）をしばらく開放しておき
、ふくれの惧れがなくなってから通気管（３）を閉鎖す
ればよい。Therefore, in waterproofing work where insufficient curing of concrete is expected, it is sufficient to leave the ventilation pipe (3) open for a while and close the ventilation pipe (3) after there is no risk of blistering.

乾燥させ防水層のふくれを防止することができる。Since the illustrated embodiment is configured as described above, even if an air pocket (7) occurs under the waterproof layer (+), the air pressure and vapor pressure are not released upward, and the slab (
2) through a small-diameter ventilation pipe (3) that runs vertically through it, as shown by the arrow (8) in Figure 1, to prevent the waterproof layer (1) from blistering. In addition, if there is a swollen area or water leakage, the inside can be dried by forced air intake and exhaust through the ventilation pipe (3) to prevent the waterproof layer from blistering.

所とは可成り離隔しているため、前記欠損部分が判定で
きないことが往々にしであるが、この場合、雨天の日等
に通気管を開口せしめてみることによって、欠陥部が近
いか否か判定し易く、漏水の処理が容易になる。-S, the defective part of the waterproof layer and the part where water leaks and causes bearing are quite far apart, so it is often impossible to determine the defective part, but in this case, on a rainy day etc. By opening the vent pipe at the same time, it is easier to determine whether the defective part is nearby, and it becomes easier to treat the leakage.
更に前記スラブに配設された通気管は、スラブコンクリ
ート打設時における天端の定規となり、施工が容易にな
る。Furthermore, the ventilation pipe provided in the slab serves as a ruler at the top when concrete is poured into the slab, making construction easier.

し、漏水を生起するようなことがなく、また専用品を使
用しないで済むので、コストが低減される。Furthermore, according to the present invention, a ventilation pipe is provided that runs vertically through the slab without using a dedicated part for deaeration holes that protrudes above the waterproof layer as in the past. There is no risk of damage to the waterproof layer caused by collisions with roads or objects, and no water leakage occurs, and there is no need to use specialized products, so costs are reduced.

ふくれを防止しうるちのである。The invention as claimed in claim 2 is characterized in that the ventilation pipe provided in the slab can be opened and closed freely, and in waterproofing work where insufficient curing of concrete is expected, the ventilation pipe is left open for a while to avoid the risk of blistering of the waterproof layer. It closes after the water is gone and prevents the waterproof layer from blistering.
