Such a width timber is made of a long plate material having a length substantially equal to the length of the scaffolding plate, and is fixedly attached to a column or a horizontal column to prevent the plate from falling off.

Then, in order to eliminate the gap generated between the skirting board and the scaffolding material, there has been proposed a skirting board in which an auxiliary board material for eliminating the gap is provided in the skirting board (see Patent Document 1, etc.). ). Thus, in order to improve the safety of the scaffolding plate of the temporary scaffolding, the installation of the width wood is widely spread.

In recent years, in order to secure the safety of the temporary scaffolding near the scaffolding, the number of members such as width wood and handrails has increased, which causes a problem such as an increase in labor and time for assembling the temporary scaffolding. Therefore, there has been a demand for a width timber of a temporary scaffold that is easy to install while improving the safety around the scaffold plate of the temporary scaffold.

The other end 12 in the longitudinal direction of the skirting board main body 20 has a movable engaging portion 31 that engages with the second support S2, and has a rotating member 30 that rotates in the plate surface direction of the skirting board 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 body 20. Since one end 11 and the other end 12 of the skirting board body 20 are in contact with the columns S1 and S2, and are easily deformed by stress such as impact from the scaffolding side, the reinforcing board member 80 prevents the skirting board body 20 from being deformed. be able to.

The rotating member 30 is pivotally attached to the skirting board main body 20 by a bolt member 70, and is rotatably attached in the plate surface direction of the skirting board main body 20, that is, parallel to the plate surface. Since the width of the skirting board main body 20 in the thickness direction does not become larger than that of rotating at right angles to the plate surface because it rotates parallel to the plate surface, it is space-saving and is advantageous during transportation. As shown in FIG. 2, a movable engaging portion 31 is formed at the tip of the rotating member 30. The movable engaging portion 31 engages with the second supporting column S2 at an engaging position 35 and its engaging position. Is moved to and from the engagement release position 36 in which is released. Since the movable engaging portion 31 can be attached to the second support column S2 only by moving the rotating member 30, the width wood 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. When the movable fastening portion 31 is arranged at the fastening position 35, the movable fastening portion 31 and the fixed fastening portion 21 are symmetric to each other in the skirting board body 20 as shown in FIG. It will be tied up with. As a result, the width wood 10 is stably installed. Then, the engagement release position 36 of the movable engagement portion 31 for releasing the engagement with the second support is a parallel position pp which is erected 90 degrees upward with respect to the second support. The engagement of the movable engagement portion 31 with the second support column S2 can be easily released with a small amount of movement.

Further, as shown in FIGS. 2 and 3, the rotating member 30 may be attached to the skirting board body 20 via the covering member 50. The covering member 50 can regulate the rotating direction by covering a part of the rotating member 30, particularly the vicinity of the rotating shaft, and can further stabilize the movement of the movable engaging portion 31. In addition, for example, when the width wood 10 is subjected to a strong impact or the like, it is possible to prevent the rotation member 30 from being bent and the engagement with the second support S2 being released. In addition, the covering member 50 is provided with stopper portions 51 and 52 for positioning the engagement position 35 and the engagement release position 36. Both stopper portions 51, 52 are arranged in an L shape. Accordingly, the rotating member 30 abuts on the stopper portions 51 and 52 and stops at the engagement position 35 or the engagement release position 36, so that the movable engagement portion 31 and the second support column S2 can be more firmly engaged. Even when the engagement is released, the engagement release position 36 is easy to understand and the handling is easy. Although not shown, when the rotating member 30 moves, a concave portion, a convex portion, or a linear portion is formed on the rotating member 30 or the covering member 50 so that a click feeling can be obtained at the engagement position 35 and the engagement release position 36. You may form a part etc. When the covering member 50 is not provided, these are formed in the skirting board body 20.

Then, as shown in FIG. 3, the movable engaging portion 31 is provided with a joining member 60 having a curved surface 61 joined to the circumferential surface Sf of the second support column S2. The joining member 60 is made of a metal plate having substantially the same thickness as the movable engaging portion 31. When the movable engaging portion 31 is arranged at the engaging position 35, the joint member 60 fills the gap between the circumferential surface Sf of the second support column S2 and the movable engaging portion 31. As a result, the lateral displacement of the width wood 10 is prevented, and the possibility that it will fall out due to the disengagement from the columns S1 and S2. Further, rattling of the movable engaging portion 31 is suppressed, and the generation of noise and the like can be prevented.

When the movable engaging portion 31 is provided with the joining member 60, the notch 38 is formed in the movable engaging portion 31, as shown in FIGS. When the movable engaging portion 31 overlaps the width wooden pieces 10 at the engagement release position 36, as shown in FIG. 4, a part of the joining member 60 of the other width wooden pieces 10 is attached to the movable side cutout portion 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 limited when the width boards 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 engaging portion 21 also has a fixed-side cutout portion 28. In addition, the reinforcing plate member 80 is formed in a substantially U-shape in a side view, so that when the width woods 10 are overlapped with each other, the reinforcing plate member 80 of the other width woods 10 is fitted in the fixed side cutout portion 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, since the notches 28 and 38 are formed in both the fixed engaging portion 21 and the movable engaging portion 31, when the skirting boards 10 are overlapped with each other, at both ends 11 and 12 of the skirting board body 20. The upper arm 81 and the joining member 60 are housed in the notches 28 and 38, respectively. Since the widthwise wooden pieces 10 are stably overlapped with each other, unexpected dropping and rattling are suppressed, which is safe and easy to carry.

The ends of the skirting board body 20 and the reinforcing plate member 80 are formed by bending. The bending strength of the plate material improves the bending strength, and the skirting board body 20 and the reinforcing plate member 80 are less likely to be deformed. Further, by bending the tip end of the edge plate member 40 downward, the jumping up of the tip end of the edge plate member 40 is suppressed, the step with the scaffold plate P is reduced, and a trip of 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 engaging portion 25 of the fixed engaging portion 21 is obliquely attached to the first support column S1 from the scaffolding plate P side (inner side), and the width wood using the first support column S1 as an axis. 10 is moved and the skirting board main body 20 is arranged between the columns S1 and S2. At this time, as shown in FIG. 6B, the movable engagement portion 31 of the rotating member 30 is in the engagement release position 36. Then, as shown in FIG. 6C, the movable engaging portion 31 of the rotating member 30 is rotated from the engagement releasing position 36 to the engaging position 35, and is movable relative to the second support column S2. Is laid down. Thus, the width wood 10 of the present invention is attached to the columns S1 and S2 by a simple method. In addition, the installation is easy because no tools are required for the installation. Further, since the width wood 10 can be detached from the columns S1 and S2 in the reverse order, the detachment is easy.

Although both fastening portions 21 and 31 of the width wood 10 according to the embodiment of the present invention are plate-shaped members, they may be formed by bending a rod-shaped member to form both fastening portions. In the case of a rod-shaped member, the ends of the engaging portions 25 and 35 can be stably attached by forming the tips to have two or more forks.
