At the other end 12 of the siding board main body 20 in the longitudinal direction, there is a movable engaging portion 31 that is hung on the second support column S2, and a rotating member 30 that rotates in the plate surface direction of the stile board main body 20. As shown in FIGS. 1 to 3, in the present embodiment, the rotating member 30 is formed by bending and deforming a plate-shaped member into an L-shaped combination, and a movable engaging portion 31 is formed at the tip thereof. .. In this embodiment, the reinforcing plate members 80 are attached to both ends 11 and 12 of the skirting board main body 20. Since one end 11 and the other end 12 of the siding board main body 20 are in contact with the columns S1 and S2 and are easily deformed by stress such as an impact from the scaffolding side, the reinforcing board member 80 prevents the sill board main body 20 from being deformed. be able to.

The rotating member 30 is pivotally attached to the width wood board main body 20 by a bolt member 70, and is rotatably attached to the width wood board main body 20 in the plate surface direction, that is, in parallel with the plate surface. Since it rotates in parallel with the plate surface, the width in the thickness direction of the skirting board main body 20 does not become larger than that in rotation at right angles to the plate surface, which saves space and is advantageous for transportation and the like. As shown in FIG. 2, a movable engagement portion 31 is formed at the tip of the rotating member 30, and the movable engagement portion 31 has an engagement position 35 and its engagement with the second support column S2. Moves between the engagement release position 36 and the engagement release position 36. Since the movable engaging portion 31 can be engaged with the second support column S2 only by moving the rotating member 30, the width timber 10 can be easily attached and the work efficiency can be improved.

Further, the engagement position 35 of the movable engagement portion 31 is an orthogonal position rp with respect to the second support column. When the movable engagement portion 31 is arranged at the engagement position 35, the movable engagement portion 31 and the fixed engagement portion 21 have the columns S1 and S2 at symmetrical positions on the timber board main body 20, as shown in FIG. Will be attached. As a result, the width timber 10 is stably installed.

The joining member 60 is made of a metal plate having substantially the same thickness as the movable engaging portion 31. When the movable engagement portion 31 is arranged at the engagement position 35, the gap between the circumferential surface Sf of the second support column S2 and the movable engagement portion 31 is filled with the joining member 60. As a result, the possibility that the width timber 10 is prevented from laterally displaced and the support columns S1 and S2 are disengaged and fall off is reduced. Then, the rattling of the movable engaging portion 31 can be suppressed and the generation of noise and the like can be prevented.

When the joint member 60 is provided in the movable engagement portion 31, a notch 38 is formed in the movable engagement portion 31 as shown in FIGS. 2 and 4. When the movable engaging portion 31 overlaps the width timbers 10 with each other at the engagement release position 36, as shown in FIG. 4, a part of the joining member 60 of the other width timber 10 to the movable side notch 38. Is inserted. As a result, interference with other width timber is avoided, space is saved, and transportation and storage costs are suppressed. Further, since the movement of the rotating member 30 is restricted when the width timbers 10 are overlapped with each other, the rotating member 30 does not move during transportation, which is safer.

Then, as shown in FIG. 5, it is preferable that the fixed side notch 28 is also formed in the fixed engaging portion 21. At the same time, the reinforcing plate member 80 is formed in a substantially U-shape in the side view, so that when the width woods 10 are overlapped with each other, the reinforcing plate member 80 of the other width wood 10 is formed in the fixed side notch 28. The upper arm portion 81 is partially inserted. As a result, interference with other width timber is avoided, space is saved, and transportation and storage costs are suppressed. In particular, by forming the notches 28 and 38 in both the fixed engagement portion 21 and the movable engagement portion 31, when the width timbers 10 are overlapped with each other, the both ends 11 and 12 of the width wood board main body 20 The upper arm portion 81 and the joining member 60 are accommodated in both the notch portions 28 and 38, respectively. Since the width timbers 10 are stably stacked with each other, unexpected dropping and rattling are suppressed, and it is safe and easy to carry.

The end positions of the skirting board main body 20 and the reinforcing board member 80 are formed by bending. The bending force of the plate material is improved by bending the plate material, and the skirting board main body 20 and the reinforcing plate member 80 are less likely to be deformed. Further, by bending the tip of the edge plate material 40 downward, the tip of the edge plate material 40 is suppressed from jumping up, the step with the scaffolding plate P is reduced, and tripping by an operator or the like can be prevented.

Next, a method of attaching the width wood 10 of the present invention to the columns S1 and S2 will be described with reference to FIG. As shown in FIG. 6A, the fastening portion 25 of the fixing fastening portion 21 is diagonally fastened to the first support column S1 from the scaffolding plate P side (inside), and the width timber is centered on the first support column S1. The width wood board main body 20 is arranged between the columns S1 and S2 by moving the ten. At this time, as shown in FIG. 6B, the movable engagement portion 31 of the rotating member 30 is the engagement release position 36. Then, as shown in FIG. 6 (c), the movable engagement portion 31 of the rotating member 30 is rotated from the engagement release position 36 to the engagement position 35, and the movable engagement portion 31 with respect to the second support column S2. Is hung up. As described above, the width timber 10 of the present invention is attached to the columns S1 and S2 by a simple method. In addition, installation is easy because no tools are required for installation. Further, since the width wood 10 can be removed from the columns S1 and S2 in the reverse procedure, it is easy to attach and detach.
