The pin 4 has a positional relationship between the connecting portion 15 (more specifically, the lateral projecting members 16 and 16) of the vertical rod member 1 (or 2) and the fitting end portion 32 of the horizontal rod member 3 shown in FIG. The pin holes 161, 321, 322, and 162 are sequentially penetrated from above, and can abut on the rear edge 161b of the pin hole 161, the front edge 322a of the pin hole 322, and the rear edge 162b of the pin hole 162.

FIG. 5 is a side view of another horizontal bar member 30 according to the present invention. The rod member 30 is for erection of the scaffold plate 6, and includes a rod pipe 31a having the same inner and outer diameter as the rod pipe 31 of the horizontal rod member 3 but shorter than that, and one end of which is the horizontal pipe. It is a fitting end 32 having the same configuration as the rod member 3, and has pin holes 321, 322 of the same size and arrangement. An oblique support member 34 extending toward the vertical bar member 1 (or 2) and descending is fixedly provided at the other end portion 33, and the vertical bar member 1 ( Alternatively, it is provided with a half-cylindrical member 341 that comes into contact with the surface of the rod tube 11 (or 21) of 2).

The vertical bar members 1 and 2 and the horizontal bar members 3 and 30 described above are components of a scaffolding assembly tool, and the scaffolding is assembled as follows, for example. As shown in FIGS. 6A and 6B, for example, the vertical bar member 1 to be a scaffolding pillar is installed on the scaffolding assembly ground L near the site where the general house H is constructed. First, the base plate 7 is arranged, and the jack 8 serving as a base is arranged thereon. Then, as shown in FIGS. 6 (A) and 6 (B), each jack 8 is connected to the vertical connecting portion 14 below the vertical bar member 1, and the member 1 is erected on the jack. In the jack 8, a screw rod 72 is erected on the base body 81, a female screw ring 83 is screwed onto the screw rod 82, and an operation arm 84 is projectingly provided on the ring. The screw rod 82 has an outer diameter that fits into the lower connecting portion 14 of the vertical rod member 1 with as little clearance as possible. Accordingly, the lower rod 14 of the vertical rod member 1 is fitted onto the screw rod 82, and is vertically supported by the female screw ring 83.

The height of each vertical bar member 1 thus erected on the jack 8 is adjusted by rotating the female screw ring 83. A height-adjusted horizontal bar member 3 of the type shown in FIG. 3, of suitable length, is arranged between adjacent vertical bar members 1, 1 with the fitting end 32 at the same height. The vertical rod members 1 and 1 are inserted deeply into the pair of upper and lower horizontal protruding members (16, 16) and (16, 16) in the horizontal connecting portions 15 and 15.

In this state, the connecting pin 4 is driven into the pin holes 161, 321, 322, 162 in each connecting portion 15 as shown in FIG. At this time, the pin 4 contacts the trailing edge 161b of the pin hole 161 and the leading edge 322a of the pin hole 322 and the trailing edge 162b of the pin hole 162, relatively moves the leading edge 322a of the pin hole 322, and connects them. Push it to the back of section 15. As a result, the fitting end portion 32 of the horizontal bar member 3 is strongly pressed against the vertical member 17 connecting the horizontal projecting portions 16 and 16 of the connecting portion 15, and is stabilized there.

Further, the lower connecting portion 23 of the vertical rod member 2 shown in FIG. 2 is inserted and erected on the solid rod 12 of the upper connecting portion 13 of each vertical rod member 1, and the vertical rod members 2 and 2 are also connected to each other. In the same manner as the installation of the horizontal bar member 3 in the case of the vertical bar member 1, the required number of the horizontal bar members 3 are firmly assembled and installed. A scaffolding plate 6 can be installed on the horizontal bar member 3 if necessary. Thus, the scaffolding can be easily and firmly assembled in sequence.

If necessary, the horizontal bar member 30 shown in FIG. 5 is connected to the vertical bar member 1 or 2 on which the scaffolding plate is hung. This connection is also supported by inserting the fitting end portion 32 of the horizontal bar member 30 into the horizontal connecting portion 15 of the vertical bar member and driving the connecting pin 4 into the pin hole in the same manner as in FIG. Since the half-cylindrical member 341 at the lower end of the member 34 is brought into contact with the surface of the rod tube 11 (or 21) of the vertical rod member, it can be assembled robustly, and the scaffolding plate 7 is attached to the adjacent horizontal rod member 30. Can be erected.

The scaffold thus assembled can be disassembled by removing the scaffold plate 7 at each part and tapping the connecting pin 4 from below to disassemble the scaffold. Each of the vertical bar members 1 and 2 and the horizontal bar members 3 and 30 described above has a simple structure and can be manufactured at low cost. It is also easy to transport. The present invention is not limited to the above embodiment, but can be implemented in various modes.

For example, in each vertical bar member 1 and 2, its height (length), the number of connecting portions 15, the position, the number of pairs of upper and lower horizontal projecting members 16 in each connecting portion 15, and the like are The present invention is not limited to the above-mentioned embodiment, but is arbitrary. In addition, the scaffolding assembly bar member and the scaffolding assembly tool of the present invention can be widely used not only in the construction of a general house as in the above-described embodiment but also in various fields.
