The front and rear wall surfaces of the manhole 1 are open at the tip of the pipe 2, and The cable 3 drawn from 2 is gently curved and offset in the manhole 1. Reference numeral 4 denotes an elevator door for construction and inspection, which connects the ceiling of the manhole 1 and the road surface 5.

On the wall surfaces on both sides of the manhole 1, a metal plate 6
Are arranged and fixed at appropriate intervals. A plurality of bolt holes 7 are provided through these uprights 6 at appropriate intervals in the vertical direction, and a receiving object 8 is attached by bolts and nuts inserted through these bolt holes 7. . The cable 3 is supported on the receiving object 8 at an appropriate position according to the offset shape via the insulator 9 or the like. The upright 6 is made of a section steel having an L-shaped cross section, and normally, as shown in FIG. 6, the foundation bolt 11 driven into the wall surface 10 is inserted into the bolt hole of the upright fixing surface 6a, and the nut 1
It is fixed to the wall surface 10 by tightening with 2. However, in an old-fashioned manhole in which the wall surface 10 is made of brick, the strength is insufficient to drive and fix the foundation bolt 11. In this case, it is possible to reinforce the foundation bolt driving surface with mortar cement,
The work is complicated and impractical.

In such a case, as shown in FIGS. 7 to 9, a support metal fitting 13 for mounting the upright object is used. The support fitting 13 includes a base plate portion 14, an upright metal fitting portion 15 planted in the base metal portion 14, and reinforcing portions 16 connected to both sides of the upright metal fitting portion 15, and is used for slabs on the ceiling and floor. The driven foundation bolt 11 is fixed to the ceiling and floor of the manhole 1 by inserting it into the foundation bolt insertion hole 14 a provided through the board portion 14 and tightening it with the nut 12. In this way, the uprights 17 are attached between the upper and lower support fittings 13 fixed to the manhole 1. In this case, some upper and lower bolt holes 17a (three in the illustrated example) of the upright 17 are used, and the bolts inserted between the bolt holes 17a and the bolt holes transparently provided in the upright mounting portion 15. It is attached by tightening 18 with a nut 19.

[0006]

Generally, manhole 1
Since the inside is narrow, and the mounting position of the receiving object 8 needs to be changed depending on the number of laying cables and the size of the offset, it is desirable that the mounting position is not restricted as much as possible. However, as mentioned above,
In the conventional support member 15 for mounting the upright object, when the upright object 17 is attached, several bolt holes 17 above and below the upright object 17 are attached.
Since a is used, the receiving object 8 cannot be attached to those bolt holes. As a result, there is a problem in that dead spaces occur in the manhole 1 near the top and bottom, and the space in the manhole cannot be effectively used.
