キャップに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid leakage prevention cap, and in particular, a plurality of prestressed concrete bridge girders are arranged on a pier in the width direction of a bridge, and a PC is inserted in a sheath penetrating in the width direction of each bridge girder. Place the cable under tension,
When fixing both ends of the C cable to the side surface of the bridge girder positioned at both ends of the bridge girder with fixing fittings, and then press-fitting the grout into the sheath to integrate the plurality of bridge girders,
The present invention relates to a liquid leakage prevention cap that covers end portions of a fixture and a PC cable and prevents grout that is press-fitted in a sheath from leaking to the outside.

している。In such a case, each bridge girder is provided with a through hole in its width direction, and a tubular sheath is fitted in this through hole. In order to connect and integrate these bridge girders, insert a piano wire (PC cable) into each sheath of each bridge girder that is lined up to communicate, and connect one end of this PC cable to one of the arranged bridge girders. Fix with the fixing metal fittings, tension the other end of the PC cable with the dedicated jack, and fix the other end of the PC cable with the fixing metal fittings to the bridge girder arranged at the other end of the bridge girders while keeping the PC cable tensioned. I am trying.

The chuck member is formed into a cylindrical grip member, and an anchor plate is arranged between the grip member and the side surface of the bridge girder.

Is pressed into the gap between the sheath and the PC cable so that the PC cable is embedded in the grout. This grout is press-fitted by a dedicated pump from an injection pipe attached to a grout injection hole formed in anchor plates provided at both ends of the cable.

ようにしていた。At this time, since the grout may leak from the gap between the chuck members, in order to prevent the grout from leaking, the mortar kneaded with cement, sand and water is made into a dumpling shape and the tip of the fixing member is fixed. I was trying to harden it.

った。However, since the number of PC cables is 40 to 60 on one ordinary bridge and the fixing fittings at both ends are about 80 to 120, the mortar at the end of the fixing fitting is hardened. It takes a lot of time and labor, and it takes time to remove this stain because the surroundings are soiled with mortar.Besides, it is necessary to wait for the mortar to harden before carrying out the grout injection. It started after the hardening of the mortar and was delayed, and there was a problem that the mortar could not be hardened when it was raining.
【０００８】そこで本発明の発明者は、これらの不具合

As shown in FIG. 9, by using a cylindrical mounting jig 105 and a hammer 106, it is fitted into the PC cable 2 and the fixing bracket 5 to be mounted. Then, as shown in FIG. 8, the gap between the chuck member 3 and the tip of the PC cable 2 which is the liquid leakage place is covered with the liquid leakage prevention cap 100, and the inner peripheral surface 102 of the liquid leakage prevention cap 100 is covered.
The a is tightly fitted to the outer peripheral surface of the grip member 4, and the vicinity of the end of the PC cable is in a hermetically sealed state so that the grout does not leak.

外れてグラウトが漏れ出てしまうおそれがある。By the way, in recent years, the standard specification for concrete has been revised and the specifications for grout have been changed, so that the injection pressure of grout into the sheath has been increased to about 8 kg / cm 2 , for example. However,
In the above-described conventional liquid leakage prevention cap 100, since the cap 100 is simply attached to the grip member 4 by the elasticity of the synthetic resin which is the material thereof, the liquid leakage prevention cap 100 is attached to the grip member 4 by the injection pressure of the grout. It may come off and grout may leak out.
