Further, a nut 42 is fixed to a through hole portion formed on the lower surface of the outer tube member 17 on the free end side, a bolt 43 is screwed into the nut 42 to penetrate the through hole, and a tip portion of the nut 42 is inserted into the inner tube member. The inner pipe member 18 is fixed by pressing it against the inner pipe member 18.

Next, a method of using the bracket having the above structure will be described with reference to FIGS.

First, as shown in FIG. 8A, the bracket 10 is attached to the scaffolding frame A of the temporary scaffolding via the clamps 12, and the outer pipe member 17 for accommodating the inner pipe member 18 is integrated with the rotating member 15 by its own weight. When the bolt 16 that is the shaft attachment portion is rotated downward, the rotation member 15 having a substantially U-shaped cross section abuts the support member 11 to hold the outer pipe member 17 in a horizontal state. At this time, the unconstrained free end of the reinforcing member 21 axially attached to the outer pipe member 17 is guided by the connecting member 23 and is locked by the locking body 27 arranged on the column member 11. The free end of the reinforcing member 21 is restricted by the connecting member 23 and acts as a reinforcing diagonal member that supports the outer pipe member 17 from below without displacement. Next, the inner pipe member 18 is pulled out from the outer pipe member 17, adjusted to an appropriate length, and fixed with bolts 43. Then, a scaffolding board B is placed between the adjacent brackets 10 attached to the scaffolding frame A of the temporary scaffolding to form a working scaffolding.

Further, since scaffolding boards B supported by the brackets 10 are an obstacle when performing construction such as painting of outer walls of buildings or tiles, the scaffolding boards B are mounted as shown in FIG. 8 (b). The outer pipe member 17 and the inner pipe member 18 are flipped upward while keeping the same. As a result, the outer pipe member 17 rotates about the bolt 16 of the shaft-attached portion of the rotating member 15 that is integrally fixed. Along with this, as shown in FIG. 9A, the lever body 28 also rotates, and the engaging pin 30 biased toward the center of rotation by the tension spring 32 also moves along the upper edge of the support tool 4. To move. When the outer pipe member 17 reaches the upright position as shown in FIG. 8C, the engagement pin 30 faces the locking groove 33 of the support fitting 14 as shown in FIG. 9B, and the pulling force of the tension spring 32 is pulled. Is locked in the locking groove 33 by being locked by the scaffold plate B being flipped up.

Further, in order to release the lock and return the scaffolding plate B to the original horizontal state, the lever body 28 is pulled to pull out the engaging pin 30 from the locking groove 33 as shown in FIG. 9C. It is rotated in the direction of the arrow and temporarily hooked in the concave portion 34 of the rotating member 15 to release the restraint of the rotating member 15. As a result, the outer pipe member 17 can be rotated and the original horizontal state can be obtained. Then, when the outer pipe member 17 becomes horizontal, the lever body 28 28 is fitted into the original guide groove 31.

The means for locking the scaffolding plate B in the flipped-up state is not limited to the above-mentioned embodiment, and it goes without saying that it can be appropriately modified.

[0023]

[Effect of device]

 As described above, according to the present invention, the outer pipe member 17, which is a horizontal member on which the scaffold plate of the bracket is placed, is rotatably attached to the support column 11, and the outer pipe member 17 is placed in a horizontal state from below. Since the reinforcement member 21 serving as a diagonal member that is supported by the link mechanism is configured so that the outer pipe member 17 can be flipped up, the scaffolding board B is interposed between the brackets 10 mounted on the scaffolding frame A adjacent to the temporary scaffolding. If the table is placed, the reinforcing member 21 composed of a link mechanism acts as a reinforcing diagonal member to support the scaffolding plate B, and it is possible to achieve sufficient strength performance as a working scaffolding, and at the same time, to protect the outer wall of the building. When carrying out construction such as painting or tiling, scaffolding board B can be flipped up so that it does not get in the way, and work can be performed efficiently.

Further, if a locking means for locking and fixing the outer pipe member 17 in a state where the outer pipe member 17 is flipped upward is provided at the shaft attachment portion between the pillar member 11 and the outer pipe member 17, the scaffolding plate B can be moved upward. It can be locked in the condition that it is flipped up to the side, and it is safe without falling.
