(7) is a single tube, and (8) is a scaffold plate.

Next, the operation will be described. After the pillar (2) is built, for example, through holes (22) are drilled at appropriate places in the upper, middle and lower parts of the pillar (2) as shown in FIG.
Insert the bolt (20) into the bolt (20) in 2) and screw the nut (21) into the tip screw. Then, just above the bolts (20) and nuts (21), the receiving band (a)
After opening and closing, the receiving band (a) is fitted to the pillar (2) as shown in FIG. 5, and then the split bodies (12) and (12) are connected to their cut grooves (14), The bolt (17) and nut (16) inserted in (14) can be tightened and fixed, and the receiving band (a) can be placed on the bolt (20) and the nut (21) to fix the pillar (2). The receiving band (a) is fitted to the upper part, the middle part and the lower part.

Then, as shown in FIG. 1, the hooks (3) of the scaffold bracket (b) are respectively attached to the three-way latches (1) of the upper receiving band (a) and the four-way latches (1) of the intermediate receiving band (a). When the leg (34) of the scaffold bracket (b) is erected as shown by the solid line in FIG. 7 and the contact plate (37) with the elastic plate (36) is applied to the column (2), the column ( Any number of scaffold brackets (b) are attached to 2).

Then, as shown in FIG. 3, after hooking the hooks (40) on both sides of the triangular bracket (e) to the latches (26) on the opposite sides of the adjacent scaffold brackets (b) and (b) respectively,
Scaffold brackets (b), stop pieces (27) on the opposite side of (b)
Is rotated outward with the bolt (28) as a fulcrum, thereby preventing the triangular bracket (e) from rising and installing the triangular bracket (e) between the scaffold brackets (b) and (b).

Then, in each scaffold bracket (b), the lower end of the pillar (41) of the handrail (f) is fitted into the locking piece (31) as shown by the chain line in FIG. Place and clamp (3
After tightening with (0), the through holes (44) at both ends of the handrail rod (43) are fitted into the stop rods (42) of the adjacent support columns (41), respectively, and the space between the adjacent support columns (41). When the handrail rod (43) is erected, as shown in FIG. 1, several scaffold brackets (b), triangular brackets (e), columns (41), and handrail rods ( 43) forms a scaffold with a handrail (f) surrounding the pillar (2).

In addition, as shown in FIG. 1, the hook (4) of the ladder (c) is hooked on the latch (1) inside the upper receiving band (a), and the latch (47) of the ladder (c) is used as a pillar. By fitting and abutting against (2), the ladder (c) is attached to the pillar (2).

On the other hand, as shown in FIG. 2, when the hook (3) of the scaffold bracket (b) is hooked on the outer latch (1) of the lower receiving band (a) of the pillar (2) and the same operation as above is performed, A scaffolding bracket (b) is attached to the pillar (2).

Also, the latch (1) inside the lower receiving band (a)
Hook the hook (5) of the scaffolding clamp hardware (d) to
If the metal fitting (49) of the scaffolding clamp metal fitting (d) is fitted and applied to the pillar (2), the scaffolding clamp metal fitting (d) is attached to the pillar (2). Then, the single pipe (7) is clamped by the clamps (6), and the scaffold plate (8) is placed on the single pipes (7) on both sides to place the scaffold on the lower part of the pillar (2). .

Thus, if the scaffold is configured as described above, the worker can use the scaffold plate (8), the middle scaffold of the pillar (2), or the ladder (c) to use the upper scaffold of the pillar (2). Climb up and use those scaffolds as a working floor for joining columns (2) and beams (9).

The scaffolding plate (8) can also be used as a scaffolding similar to the conventional one.

Further, when the scaffold bracket (b) is transported or stored, the legs (34) of the scaffold bracket (b) are indicated by chain lines in FIG.
The leg (34) is folded when it is rotated toward the frame (23) with the 5) as a fulcrum.

The method of attaching the scaffolding bracket (b), the ladder (c), and the scaffolding clamp hardware (d) to the receiving band (a) is not limited to the above-mentioned attaching method, and the receiving band (a)
The desired scaffold can be constructed by arbitrarily attaching any of the latches (1) on the four sides.

Even when the pillar (2) is H-section steel, it can be used in the same manner as above.

(Effect of the Invention) The temporary scaffolding device of the present invention has the following remarkable effects.

(1) A steel band is used as a pillar of a scaffold, a receiving band is fitted to the pillar, and a scaffold bracket is hung on the receiving band, and a triangular bracket for scaffolding is hung between the scaffold brackets. The scaffolding is constructed by attaching the handrails that extend around the outer periphery of the scaffolding bracket and the triangular scaffolding bracket. Therefore, (a) the support for scaffolding is not required, which saves materials and is convenient in handling.

(B) Since it is possible to provide a required scaffold at a position of a required height at one place or a plurality of places of the pillar, it is useful in the work.

(2) As for the receiving band, the other end of the two shape-divided bodies provided with latches on both pieces is screwed and the one end is tightened with bolts and nuts to fit on the pillar, so that the receiving band is integrated. It is easy to handle because the receiving band is easily attached to and detached from the pillar.

(3) Scaffolding brackets and triangular brackets for scaffolding are
Attach by hooking each hook. Therefore, (a) the scaffold bracket and the triangular bracket for the scaffold can be freely and easily attached and detached, which is convenient in terms of work.

(B) All scaffold brackets and triangular scaffold brackets are located on the same plane to form a flat scaffold.

(C) The scaffold bracket and the scaffold triangle bracket are attached securely.

(4) The scaffolding bracket and the scaffolding triangular bracket form a scaffold in the shape of a column, and it is easy to work on the scaffolding in conjunction with mounting the handrails on the outer periphery of the scaffolding, and it is beneficial for safety.

(5) When a ladder or scaffolding clamp hardware is hooked and attached to one latch of the receiving band, the ladder, scaffolding clamp hardware, etc. can be used. When the ladder is attached, the ladder is attached. It can be used to climb and descend to each floor.

(6) It has a simple structure and can be manufactured easily and inexpensively.
