A formwork F with a steel shell structure divided into multiple compartments B... is manufactured on land, and after being towed to the water at the construction site, each compartment is filled with water and sunk to the bottom of the water at the construction site. ,
Next, a new construction method was developed, in which water is drained from each section one by one and concrete is poured one by one instead, and plans are being made to implement it. In addition, the figure shows a formwork for constructing a vertical shaft of an immersed tunnel, and in the figure, reference numerals F2, . . . indicate partition walls for reinforcing the formwork, and F3 indicates a bottom plate.

・is arranged to penetrate through the partition wall F1, and the sixth
As shown in the figure, each threaded reinforcing bar S is connected to the partition wall F1 by the grooves N and N screwed onto the threaded reinforcing bar S.
It is fixed to the partition wall F1 by sandwiching it from the front and back.

Section B, which was drained because the water was not sufficiently stopped between
In addition, water may enter from the adjacent undrained section B, which may affect the hardening time of the poured concrete, the strength after hardening, or the threaded reinforcing steel S.

前記ネジ節鉄筋Ｓに対して、シール部材を十分に追従さ
せることができず、隔壁とネジ節鉄筋との間を確実に止
水することができないという問題がある。Therefore, it is conceivable to interpose an annular sealing member such as an O-ring between the nut N and the partition wall F1. However, the inside of section B of formwork F is narrow, and it is difficult to tighten the nut N using a large wrench that can be tightened with high torque, so it is difficult to tighten the seal member. has a torque limit (usually around 4000 kg-cm)
. For this reason, as shown in FIG. 6, the surface has complicated irregularities and is likely to be eccentric with respect to the through hole of the partition wall F1.
There is a problem in that the sealing member cannot sufficiently follow the threaded reinforcing bars S, and water cannot be reliably sealed between the partition wall and the threaded reinforcing bars.
この発明は、以上の事情に鑑みてなされたものであって

を目的としている。The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a water-stop packing that can reliably stop water between a partition wall and a threaded reinforcing bar even when tightened with relatively low torque. It is an object.

る。<Function> In the water stopper/socket of the present invention having the above configuration, the threaded reinforcing bar is inserted into the insertion hole with the packing member facing the partition wall, and then the threaded reinforcing bar is inserted from behind the washer. When tightening the screws, the thick part of the center side of the packing member that protrudes toward the partition wall will dig into the complicated irregularities on the surface of the threaded reinforcing bar.
It gets between the threaded reinforcing bars and the bulkhead to stop water between the two. Furthermore, during the tightening process, the circumferential wall formed on the washer prevents the packing member from escaping outward.

If it is less than 30@, it will not be able to sufficiently follow the complicated irregularities of the threaded reinforcing bar, and on the other hand, if it is less than 30@, it will be easy to deform when water pressure etc. is applied, although it will have excellent followability. However, there is a possibility that a sufficient water-stopping effect may not be obtained.

とが好ましい。In addition, to fix the sealing member 1 and the washer 2, a non-seizable adhesive is used, and the sealing member is heated when vulcanizing the rubber material constituting the sealing member 1. 1 and the washer 2, so-called vulcanization adhesion (baking), is preferred.Also, adhesion using a normal adhesive can also be performed. Further, the packing member 1 and the washer 2 may be fixed by simply press-fitting or fitting, but if this fitting comes off during construction, the separated image parts are placed on the threaded reinforcing bar. must be moved with
Since the work becomes complicated, the packing member 1 and washer 2 are
As mentioned above, it is preferable to bond and fix by baking.

ジ節鉄筋との間の止水に適したものとなる。<Effects of the Invention> The water-stop gasket of the present invention is constructed as described above, and with the gasket member facing the partition wall, the threaded reinforcing bar is inserted into the insertion hole, and then the threaded reinforcing bar is inserted from behind the washer. When the nut screwed onto the threaded reinforcing bar is tightened, the circumferential wall formed on the washer prevents the packing member from escaping outward, causing the packing member to protrude toward the partition wall. The thicker part on the center side bites into the complicated irregularities on the surface of the threaded reinforcing bars, gets in between the threaded reinforcing bars and the partition wall, and can shut off water between the two. Therefore, the water-stop gasket of the present invention can reliably stop water between the bulkhead and the threaded reinforcing bars by force when tightened with a relatively low torque, and a large wrench that can be used for tightening with a high torque. This method is suitable for stopping water between the bulkhead and the threaded reinforcing bars in the new construction method described above, in which it is difficult to use the above-mentioned method.
