固定構造に関する。[Detailed Description of the Invention] [Industrial Application Field] When a waterproof sheet is placed on the surface of the tunnel's ground or primary lining concrete, the required location is applied to the tunnel's ground or primary lining concrete. In addition to fixing it in concrete,
The present invention relates to a structure for fixing a waterproof sheet and hanging reinforcing bars that are used at the same time to place secondary lining concrete at the fixed location.

この方法は単に防水シートを固定し得るだけで、吊鉄筋
を同時に固定支持できない。For this reason, a method of fixing the tarpaulin sheet that does not require fixing members such as concrete nails or anchor bolts to be driven into the tarpaulin sheet is desired. A fitting member is cast into the primary lining concrete inner circumferential wall with its head protruding from the inner circumferential wall surface of the primary lining concrete, and a fitting member that fits into the fitting portion. A fixing structure for a waterproof sheet has been proposed in which a predetermined part of the waterproof sheet is inserted and fitted (Japanese Utility Model Publication No. 58-146697).
This method can only fix the waterproof sheet, but cannot fix and support the hanging reinforcing bars at the same time.
本発明は上記事情に鑑みなされたもので、防水シートを

防水シートを挾持固定するようにしたものである。In order to achieve the above object, the present invention has a first structure in which both ends of a fixing device main body having an inverted concave cross section are bent inward to form bending locking portions, and these locking portions are formed. A fixing device having an insertion hole formed between the stop parts is fixed to the ground of the tunnel or the primary lining concrete 1, and the required part of the waterproof sheet is inserted into the fixing device through the insertion hole and suspended. Insert a holding body wider than the insertion opening fixed to the tip of the reinforcing bar into the fixing device from the insertion opening, and insert a presser body with a diameter equal to or wider than the spacing of the insertion opening into the male thread formed on the outer circumferential surface of the tip of the hanging reinforcing bar. A nut body having a larger outer diameter is screwed on, the nut body closes the insertion opening, and the waterproof sheet is clamped and fixed between the nut body and the bent locking part. be.

ものである。In addition, as a second structure, both ends of the fixing device main body having an inverted concave cross section are bent inward to form bent locking portions, and an insertion opening is formed between these locking portions. Fix the fixing device to the ground of the tunnel or the primary lining concrete 1-, and insert the required part of the waterproof sheet into the fixing device from the above insertion opening, which is wider than the above insertion opening fixed to the tip of the hanging reinforcing bar. A presser body is inserted into the fixture from the insertion opening, a washer body whose dimensions are larger than the interval between the insertion openings is attached to the suspension reinforcement, and this washer body is formed on the outer circumferential surface of the tip of the suspension reinforcement. The nut body screwed onto the folding locking part is tightened to the bending locking part, the washer body closes the insertion opening, and the washer body and the bending locking part clamp and fix the waterproof sheet. It is.

が確実になされるものである。In addition, to fix the tarpaulin, insert the required part of the tarpaulin into the fixing device, and insert the presser body into the fixing device.
It is easy because all you have to do is operate the nut body, and the insertion part of the waterproof sheet into the fixing device is wider than the insertion opening, so it is regulated by a presser body that prevents it from being pulled out from the insertion opening unnecessarily. At the same time, the waterproof sheet can be securely fixed because it is strongly clamped between the oak 1 integrally (first structure) or the washer body (second structure) and the bending locking part of the fixture. It is.
