The base board and the scaffolding board are integrated by bringing the lower end edge of the wooden body into close proximity or contact with the upper surface of the scaffolding board. Next, the skirting board main body is turned to the pedestal side of the building frame with these locking brackets as a fulcrum, and tilted until the upper edge of the skirting board approaches or comes into contact with the pedestal, and then the upper end of the skirting board main body. The installation of the skirting is completed by fixing the fixing brackets prepared for to the pedestal of the building frame.

  In this way, because the lower end of the baseboard is locked to the locking clamp of the scaffolding plate and is erected on the side edge of the scaffolding plate, there is no gap in the side edge of the scaffolding plate as in the past, Also, even if the scaffolding plate moves to the left or right due to any beat, the scaffolding and skirting board move together, so there is no gap, and work safety is ensured. In addition, since the locking bracket is secured with the retaining bracket, there is no risk that the locking bracket will come off due to any moment during work, etc., ensuring work safety more reliably. it can.

  Further, according to the scaffolding skirting board according to claim 2, as the fixing bracket, the upper end portion of both ends of the baseboard body is provided with a substantially J-shaped hook bracket that is hooked and fixed to the pedestal of the building frame, The hook metal fitting is pivotally mounted with its base end shaft parallel to the longitudinal direction of the skirting board body, and it can be moved back and forth in the longitudinal direction of the skirting board body so that it can be moved back and forth inward of the skirting board body I try to energize it.

  When fixing the skirting board to the pedestal of the building frame, the substantially J-shaped hook fittings provided at the upper ends of the both ends of the skirting board body are moved to the side of the skirting board body against the urging force of the spring body. After pulling and rotating and adjusting the hook portion to be substantially horizontal, the hook fitting is released and the hook portion is hooked on the pedestal of the building frame by the restoring force of the spring body to complete the fixing.

  In this way, the skirting board can be fixed in an upright state by a very simple operation, which is suitable for high-altitude work.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 and 2 show that a plurality of building frames A are erected at a predetermined interval at a construction site or the like, a scaffolding plate B is provided between the horizontal members Aa of the adjacent building frames A, and between the pillars Ab of the building frame A 1 shows a temporary scaffold formed by hooking a brace C, and a scaffolding skirting board 1 of the present invention is attached around the scaffold plate B. FIG. 3 to FIG. 5 are enlarged views of the main part, and the skirting board 1 is mainly composed of a skirting board main body 2 made of a lightweight channel steel member having substantially the same length as the scaffolding board B. The lower end of each side face 2a is provided with a locking fitting 3 for locking to the locking clamp Ba of the scaffolding plate B, and a retaining fitting 4 for preventing the locking fitting 3 from coming off. A hook metal fitting 5 which is a fixing metal fitting fixed to the pedestal pillar Ab of the building frame A is provided at the upper ends of both side surfaces 2a.

  The locking metal fitting 3 is a substantially inverted U-shaped plate-like metal fitting having a slit 6 of a predetermined width, and is arranged in parallel with both side surfaces 2 a of the baseboard body 2, and the upper end of the metal fitting 3 is widened by the shaft body 7. The wood main body 2 is pivotally attached to the lower end portions of both side surfaces 2a. Here, the slit 6 is formed to be slightly wider than the thickness of the locking clamp Ba of the scaffold plate B, and as shown in FIGS. 5 and 6, the slit 6 is located at the base end portion position of the locking clamp Ba. It can be inserted and locked from above.

  The retainer bracket 4 is a bracket formed in a substantially letter shape, and a claw portion 4a is formed on the lower end portion thereof so as to be hooked and latched on the lower end edge of the locking clamp Ba of the scaffold plate B. Yes. Similarly to the locking metal fitting 3, the retaining metal fitting 4 is also arranged in parallel with both side surfaces 2a of the skirting board body 2, and the upper end thereof is rotated by a shaft body 7 on which the locking metal fitting 3 is attached. It is pivotally attached. Therefore, as shown in the drawing, the locking metal fitting 3 and the retaining metal fitting 4 are coaxially attached to one shaft body 7 in a state of being close to each other in parallel.

  Further, the retaining bracket 4 is biased to a latching position, that is, a position indicated by a solid line in FIG. Is inserted into the base end portion of the locking clamp Ba from above and locked, the lower end portion of the retaining metal fitting 4 is once expanded against the urging force of the spring body 8 as shown in FIG. After avoiding interference with the locking clamp Ba, when the base end of the locking clamp Ba reaches a position where it can be accommodated in the slit 6, the lower end of the retaining metal fitting 4 is returned to its original position by the restoring force of the spring body 8. At this time, the claw portion 4a formed on the lower end portion of the retaining metal fitting 4 is hooked on the lower end edge of the locking clamp Ba and latched. In addition, when releasing the latch to the locking clamp Ba by the claw portion 4a of the retaining bracket 4, the upper end piece of the retaining bracket 4 is pinched with a finger against the urging force of the spring body 8. It can be easily released by turning it a little.

  Thus, if the hook 4a of the retaining metal fitting 4 is hooked on the lower end edge of the locking clamp Ba, the upward movement of the locking metal fitting 3 can be prevented, and the locking metal fitting 3 is surely prevented from coming off. be able to. Thus, if the locking metal fitting 3 is locked and fixed to the locking clamp Ba of the scaffold plate B, as shown in FIG. 5, the skirting board main body 2 can turn to the pedestal Ab side with the shaft body 7 as a fulcrum. Become.

  On the other hand, the hook metal fitting 5 is a rod-like metal fitting bent into a substantially J shape so that it can be hooked and fixed on the leg pillar Ab of the building frame A, and is provided at both ends of the baseboard body 2 and has an arc shape. The hook portion 9 is protruded laterally in the longitudinal direction of the skirting board main body 2, and the straight base shaft portion 10 is arranged in parallel with the longitudinal direction of the skirting board main body 2 so that the arrows in FIGS. The base end shaft portion 10 is externally provided with a spring body 11 and is urged inward of the skirting board main body 2. And if only the said hook part 9 is hooked on the leg pillar Ab, the baseboard main body 2 will be firmly fixed by the restoring force of the spring body 11. FIG. In this way, while being a simple operation suitable for high-altitude work, it can be securely fixed, and it does not require an installation tool or the like, and is excellent in installation workability.

  Further, the hook metal fitting 5 has a base end shaft portion 10 pivotally attached to the skirting board body 2 so that the inclination angle of the skirting board body 2 changes as shown in FIG. The hook metal fitting 5 can always be positioned horizontally so that it can be securely hooked and fixed to the pedestal Ab of the building frame A. As shown in FIG. 3, the hook metal fitting 5 is slightly curved in the upside down direction depending on the left and right sides of the baseboard body 2, and when the baseboard 1 is attached continuously to the temporary scaffolding, The hook metal fittings 5 of the baseboards 1 are designed not to interfere with each other.

  Thus, when the scaffolding skirting board 1 is attached, the slits 6 of the respective locking metal fittings 3 at both ends of the baseboard 1 are inserted into the base end portions of the respective locking clamps Ba at both ends of the scaffolding board B from above to be locked. . At this time, the claw portion 4a at the lower end portion of the retaining metal fitting 4 is hooked on the lower end edge of the base end portion of the locking clamp Ba so that the scaffolding skirting board 1 and the locking clamp Ba of the scaffolding plate B are firmly connected. Fixed to. Next, the skirting board main body 2 is turned to the side of the pedestal Ab with the shaft body 7 of the locking metal fitting 3 as a fulcrum, and is tilted until the upper end edge of the skirting board main body 2 approaches or contacts the side surface of the pedestal Ab. Subsequently, after pulling the hook metal fitting 5 against the urging force of the spring body 11 to the side of the skirting board body 2, the hook part 9 is rotated until the hook part 9 is in a substantially horizontal position to open the opening of the hook part 9. It is made to oppose the pedestal Ab. Then, when the hook metal fitting 5 is released from the state, the hook metal fitting 5 is shortened inward of the skirting board main body 2 by the restoring force of the spring body 11, and the hook portion 9 is hooked on the pedestal Ab and fixed.

  In this way, the skirting board 1 has its lower end engaged with the locking clamp Ba of the scaffolding plate B and is erected on the side edge of the scaffolding plate B, so that there is a gap at the side edge of the scaffolding plate B. It does not occur, and the scaffold board B and the baseboard 1 are integrated, so the scaffold board B is not easily shifted to the left and right, and even if it moves to the left or right at any time, it is integrated with the scaffold board B. Thus, the skirting board 1 also moves and no gap is formed in the side edge of the scaffold board B, so that safety is ensured. Further, the base metal 1 and the locking clamp Ba of the scaffolding board B are firmly fixed by the retaining metal fittings 4, and even if a strong impact is applied to the base board 1 during work, there is a risk that it will come off and fall off. Absent. Furthermore, since the operation of installing the skirting board 1 is simple as described above, it is suitable for work at a high place and the structure of the apparatus is very simple, so that the manufacturing cost can be reduced and maintenance can be performed. This is also advantageous.
