Vertical grooves 5, 4'' are provided on the left and right side walls 3, 3' of the cylindrical body 1 at intervals to support reinforcement reinforcing bars placed in the concrete. 5'.

た。[Problems to be solved by the invention] In the conventional ground wire lead-in outlet A' formed in this way, a recess 6 is formed between the flange piece 2 and the vertical ridge 4 near the flange piece 2, making it difficult to manufacture utility poles. Sometimes, when trying to hold the reinforcing bar B placed in the molding frame between the left and right vertical grooves 5, 5, for example, even if it is correctly held in the vertical groove 5 on one side wall 3, it will not work on the other side wall 3'. The reinforcing bar B may slip over the vertical ridge 4 and into the recess 6. It is extremely difficult to determine that this condition is abnormal, so if the molding frame is attached as is and concrete is poured and molded, both end surfaces of the cylinder 1 will face both the inner and outer surfaces of the concrete C as shown in Figure 8. Otherwise, the entire ground wire lead-in outlet A' was buried in the concrete C, which not only made it impossible to connect and pull out the ground wire, but also caused a serious defect that caused the pole to be rejected.

が存在することとなる。[Embodiment] In Fig. 1, reference numeral 1 denotes a cylindrical body to be installed embedded in a utility pole, and the cylindrical body 1 is formed into a vertically elongated ellipse with a length approximately equal to the concrete wall thickness of the utility pole. The cylindrical body 1 is provided with a collar piece 2 around the outer periphery at one end in the longitudinal direction, and vertical ridges 4, 4', 4'' having a required thickness at regular intervals on both left and right side walls 3, 3'. By protruding from each other, vertical grooves 5, 5' are formed between the vertical ridges 4, 4', 4' and 4'' to hold reinforcing bars buried in the utility pole. In this way, the cylindrical body 1 with the vertical ridges 4, 4', 4'' provided on the left and right side walls 3, 3' has an area between the flange piece 2 and the vertical ridge 4 adjacent to the flange piece 2.

に面一をなす高さに設けられている。 The purpose of the present invention is to close the recess 6 by protruding the baffle plate 7 into the recess 6 to prevent the reinforcing steel from slipping into it. Baffle plates 7, 7 reaching the flange piece 2 are horizontally positioned and protruded from both upper and lower ends of the vertical ridge 4 adjacent to the ridge 2. Note that each of these baffle plates 7 is provided at a height flush with a line connecting the peripheral edge of the collar piece 2 and the top of the vertical ridge 4.

As shown in the figure, in order to be able to correctly fit and hold the reinforcing bars B, B installed in the concrete in the vertical grooves 5, 5 without having to slide them into the recesses 6, 6, grounding is installed at the upper and lower positions of the utility pole D. It is possible to reliably form the insertion hole F through which the wire E is drawn in and the ground wire E which has been drawn in is drawn out.

である。[Effects of the invention] As described above, the ground wire outlet for concrete utility poles of the present invention has a baffle plate in the recess that exists between the flange piece and the vertical ridges adjacent to the flange piece on both left and right side walls of the cylindrical body. By providing this, the reinforcing bars can be prevented from slipping into the recesses during use, and the reinforcing bars can be properly fitted and clamped into the vertical grooves on both left and right walls. It is possible to reliably form an insertion hole for pulling out, and also to eliminate the occurrence of defective utility poles.
