ることがあり、この破損で商品価値を著るしく低下させ
ることがあった。Conventionally, concrete utility poles are made by placing a tubular formwork horizontally, and then rotating the concrete while applying centrifugal force.
It is formed by creating a dense pipe. In order to fix the embedding nuts for attaching the scaffolding bolts in the concrete at the predetermined positions, they are fixed to the formwork via a jig as shown in FIG. 1. That is, the fixing jig 6 shown in the same figure connects the threaded part 9 of the shaft rod 8 protruding from one end side of the mounting body 7 to be fitted into the mounting hole 14 for the formwork into the threaded hole 2 of the embedded nut 1. The screw portion ν provided on the other end side of the mounting body 7 is screwed into the threaded support 15 attached to the outer peripheral surface of the formwork 13 (see FIG. 10).
However, in general, the length of the shaft rod 8 is set to approximately match the depth of the screw hole 2 in order to securely fix the embedded nut 1, and Threaded part 9 provided in
It has been around for a long time. For this reason, when the fixing jig 6 is removed using a tool such as an impact wrench as shown in FIG.
The wobbling may damage the threads or the opening edge of the opening side corner of the screw hole 2 of the embedded nut 1 that protrudes from the utility pole surface side, and this damage may significantly reduce the product value. there were.

ようにしたものである。The present invention has been made to provide an improved fixing jig that does not cause such problems. By forming the threaded portion shorter than the length of 2, when removing the fixing jig after forming the telephone pole, the threaded portion 12 can be screwed until the threaded portion 9 is completely removed from the screw hole 2 of the embedded nut 1. It is screwed onto a supporting tool 15 so that the shaft rod 8 can be held without wobbling due to rattling of the fixing jig 6.
以下に本発明の実施例を図面と共に説明する。Embodiments of the present invention will be described below with reference to the drawings.

固定させる。FIG. 3 shows the state in which the fixing jig of the present invention formed in this way is used. In the figure, 13 is a formwork whose overall shape is tubular, and 14 is a formwork that penetrates this frame 13. The mounting holes 15 for the fixing jig 6 opened at predetermined locations are represented by threaded supports mounted around the mounting holes 14 on the outer peripheral surface of the formwork. First, as shown in Fig. 3 B), attach the embedded nut 1 to the threaded part 9 of the shaft rod 8 on the fixing jig 6 by tightening it in advance and screwing it into the threaded support. The body part 7 is fitted into the mounting hole 14 and fixed to the formwork 13.

As shown in FIG. 3(B), the threaded part 9 formed under the condition of 1>12 is completely separated from the screw hole 2, and the threaded part ν is screwed into the threaded support 15V. Since the fixing jig 6 can be removed without shaking the fixing jig 6 and causing the shaft rod 8 to wobble, the threaded portion 9 will not damage the opening side corner of the screw hole 2.

Since it is sufficient to satisfy the condition l>12, Fig.
The threaded portions 9 and 12 may be made longer, respectively, as shown in the figure. If the threaded portions 9 and 12 are made longer in this way, they can be sufficiently tightened to the formwork 13 and the embedded nuts 1, so they can be fixed by rotation during the pole forming. The jig 6 can be securely fixed to the embedded nut 1 without becoming loose.

である。As described above, the fixing jig for the embedded nut of the present invention has the length of the threaded part provided on the mounting body to be screwed into the threaded support part attached to the formwork. By making the length of the threaded part longer than the length of the threaded part on the shaft rod so that it can be screwed into the threaded hole of the pole, when removing the fixing jig after forming the utility pole, the threaded part of the shaft H can be removed completely from the threaded hole. The threaded part of the screw part is screwed into the J-knled support to hold the fixing jig without rattling, and the corner of the screw hole opening of the embedded nut can be screwed to prevent damage. The scaffolding bolt is securely screwed into the embedded nut embedded in the pole, completely eliminating the danger of climbing the pole and working at the corner, which can bring great benefits to the pole forming process.
