【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments. As shown in FIG. 2 (a), the scaffolding support metal 1 has a substantially T-shaped cross section in which a support piece 3 is vertically joined to the front end of a fixed piece 2 formed of a metal plate or the like. A cylindrical arm receiving portion 5 opening upward is provided on the outer surfaces of the fixed piece 2 and the support piece 3, and a male screw 4 is vertically projected from the inner surface of the fixed piece 2 and the fixed piece. A locking pin 13 is vertically provided on the rear portion of the inner surface of 2.

As shown in FIG. 2 (b), the scaffolding plate receiving arm 8 is provided with a locking piece 8 b projecting downward at one end of a main body 8 a and a guide piece 8 c projecting upward at the other end of the body 8 a. Etc. FIG. 1A shows an example in which an H-shaped steel 14 is used as the pillar 7, and a pair of scaffolding support hardware 1 is attached to the H-shaped steel 14. The H-shaped steel 14 is provided with a screw hole in the front part of the flange 15 and a pin hole in the rear part of the flange 15, and the male screw 4 of one scaffolding support 1 is screwed from the outer surface of the flange 15 to the screw hole. The scaffolding support 1 is attached to the H-shaped steel 14 by inserting and penetrating it, inserting the locking pin 13 of the scaffolding support 1 into the pin hole, and screwing the female screw 6 into the male screw 4 from the inner surface of the flange 15. It is fixed. The locking pin 13 prevents the scaffolding support 1 from rotating with the male screw 4 at the center, and the number of steps for tightening the nut is less than that of forming the locking pin 13 with a screw similar to the male screw 4. It is possible. The other scaffolding support member 1 facing the scaffolding support member 1 is also fixed to the other flange 15 of the H-shaped steel 14 in the same manner. Then, the locking piece 8b of the scaffolding plate receiving arm 8 is inserted and locked into the arm receiving portion 5 of the scaffolding support hardware 1, and the main body 8a of the scaffolding plate receiving arm 8 and the guide piece 8c are projected from the H-shaped steel 14, By mounting the scaffolding plate 9 on the main body 8a of the scaffolding plate receiving arm 8, the scaffolding as shown in FIG. 1 (b) is formed. The guide piece 8c prevents the scaffolding plate 9 from falling forward.

As described above, since the male screw 4 is integrally projectingly provided on the front portion of the inner surface of the fixing piece 2 in the scaffolding support member 1, it can be attached and fixed without separately using a long bolt or the like. It is also less bulky and lighter than the conventional U-shaped scaffolding support hardware 1 shown in FIG. Further, since the scaffolding support hardware 1 can be fixed to the outer surface of the pillar 7 without sandwiching the pillar 7, by mounting a pair of the scaffolding support hardware 1 on the pillar 7, the conventional U-shaped scaffolding support hardware 1 can be obtained. You can build a scaffolding similar to the one used.
