Description

  [Technical Field] The present invention relates to a scaffolding baseboard that is attached to the periphery of a scaffolding plate of a temporary scaffolding to ensure work safety.

Conventionally, scaffolding skirting boards are attached around a scaffolding board of a temporary scaffolding constructed by assembling a building frame and a scaffolding board in order to ensure work safety such as prevention of a worker from falling. As the skirting board, for example, as shown in Japanese Utility Model Publication No. 5-28278, both ends of the skirting board body are provided with substantially U-shaped locking brackets, and the locking brackets are used as pedestals of the building frame. There is something that is fixed and locked.
No. 5-28278

  However, the conventional skirting board disclosed in Japanese Utility Model Publication No. 5-28278 has a configuration in which the skirting board main body is attached only to the pedestal of the building frame. If the scaffolding plate is shifted to the side by some time and is biased to one side of the building frame, there is a possibility that the gap becomes large and the work safety cannot be sufficiently secured.

  This invention makes it a subject to provide the baseboard for scaffolding which does not produce a clearance gap in the side edge of a scaffold board, and has high work safety in view of said point.

  In order to solve the above-mentioned problems, the scaffolding skirting board according to claim 1 according to the present invention is a scaffolding skirting board that is attached to the periphery of the scaffolding board of the temporary scaffolding constructed by assembling the building frame and the scaffolding board. And a substantially U-shaped locking bracket that is engaged with a locking clamp of the scaffolding plate is pivotally attached to the lower ends of both side surfaces of the baseboard body, and the upper ends of both ends of the baseboard body Has a hook-shaped bracket that is hooked onto the pedestal of the building frame and fixed. The hook bracket is pivotally mounted with its base end shaft parallel to the longitudinal direction of the baseboard body. In addition, it is characterized in that it is urged inward of the skirting board body by a spring body so that it can advance and retreat in the longitudinal direction of the skirting board body.

  Further, in the scaffolding skirting board according to claim 2, the hook metal fitting is formed so as to be within the thickness width of the skirting board main body when rotated at a predetermined angle around the base end shaft portion. It is a feature.

  According to the scaffolding skirting board of claim 1 according to the present invention, it is a scaffolding skirting board that is attached around the scaffolding board of the temporary scaffolding formed by assembling the building frame and the scaffolding board, and both side surfaces of the baseboard body A substantially U-shaped locking bracket to be locked to the locking clamp of the scaffolding plate is pivotally attached to the lower end of the base plate, and the upper end of both ends of the skirting board body is hooked on the pedestal of the building frame. A substantially J-shaped hook metal fitting is provided, and the hook metal fitting is pivotally mounted with its proximal end shaft portion arranged in parallel with the longitudinal direction of the baseboard body, and in the longitudinal direction of the baseboard body. Since the spring body is urged inward and backward to be freely movable, if this skirting board is attached to the scaffolding board, there is no gap between the scaffolding board and the skirting board, and it is possible to always ensure high work safety.

  According to the scaffolding skirting board of claim 2, since the hook metal fitting is formed so as to fit within the thickness width of the skirting board main body when rotated at a predetermined angle around the base end shaft portion, Can be stably stacked without being bulky, and is suitable for transport and storage.

  According to the baseboard for scaffolding according to claim 1 of the present invention, the baseboard and the scaffolding board are integrated by locking the lower end of the baseboard to the locking clamp of the scaffolding board, A substantially U-shaped locking fitting that is locked to the locking clamp of the scaffolding plate is pivotally attached to the lower ends of the side surfaces of both ends. Then, when attaching the baseboard, the locking metal fitting is inserted into the locking clamp of the scaffold plate from above and locked, and placed so that the lower end edge of the baseboard body is close to or in contact with the upper surface of the scaffold plate. We are trying to integrate wood and scaffolding boards.

  In addition, the upper ends of both ends of the skirting board main body are provided with a substantially J-shaped hook metal fitting that is hooked and fixed to the pedestal of the building frame, and the hook metal fitting has a base end shaft portion parallel to the longitudinal direction of the base board main body. It is arranged so as to be pivotally mounted, and is urged inward of the skirting board body by a spring body so as to be movable forward and backward in the longitudinal direction of the skirting board body. Then, when fixing the skirting board to the pedestal of the building frame, the skirting board main body is rotated to the pedestal side of the building frame with the fixed locking bracket as a fulcrum, and the upper edge of the skirting board main body is close to the pedestal Or tilt until it touches. Next, pull the hook metal fittings of approximately J shape provided at the upper ends of both ends of the skirting board body to the side of the skirting board body against the urging force of the spring body, and turn the hook part so that it is substantially horizontal. After moving and adjusting, the hook metal 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, 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, Even if the scaffolding plate is shifted to the left or right due to any time signature, the scaffolding and the baseboard move together, so that no gap is generated, and the safety of the work is ensured. Further, the baseboard can be erected by a simple operation, which is suitable for work at a high place.

  Further, according to the scaffolding skirting board according to claim 2, when the hook metal fitting is rotated so as to be substantially parallel to the baseboard main body, the hook metal fitting is formed so as to be within the thickness width of the baseboard main body. . Then, when transporting or storing a plurality of skirting boards, rotate the hook metal fittings of each base plate so that the hook metal fittings do not protrude from the upper and lower surfaces of the base board. Will be stacked.

  Thus, it is preferable that a plurality of skirting boards can be stably stacked without being bulky by a simple operation, and there is no fear of collapse during transportation or storage.

  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. 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, and the scaffolding board B is engaged with lower ends of both side surfaces 2a of the skirting board body 2 respectively. In addition to the locking metal fittings 3 for locking onto the clamp Ba, hook metal fittings 4 are provided at the upper ends of both side surfaces 2a of the skirting board main body 2 so as to be hooked and fixed to the leg posts Ab of the building frame A, respectively. .

  3 to 5 are enlarged views of the main part, and the locking metal fitting 3 is a substantially U-shaped plate-like metal fitting having a slit 5 having a predetermined width, and is parallel to both side surfaces 2a of the base board 2. The upper end portion is pivotally attached to both side surfaces 2a of the skirting board main body 2 by the shaft body 6 so as to be rotatable. Further, the slit 5 has a width to be fitted into the locking clamp Ba of the scaffold plate B, and as shown in FIG. 5, the slit 5 can be locked by being inserted into the base end portion of the locking clamp Ba from above. I am doing so. And if the latching metal fitting 3 is latched and fixed, as shown in FIG. 5, the baseboard main body 2 will be able to turn to the pedestal Ab side with the shaft body 6 as a fulcrum.

  The hook metal fitting 4 is a rod-like metal fitting bent into a substantially J shape so that it can be hooked and fixed to the pedestal Ab of the building frame A. 7 protrudes laterally in the longitudinal direction of the skirting board main body 2, and a straight base shaft 8 is arranged in parallel with the longitudinal direction of the skirting board main body 2 in the direction of the arrow in FIGS. 3 and 4. The base end shaft portion 8 is externally provided with a spring body 9 and is urged inward of the skirting board body 2. Reference numeral 10 denotes an operation piece for operating the hook metal fitting 4. And if only the said hook part 7 is hooked on the leg pillar Ab, the baseboard main body 2 will be firmly fixed by the restoring force of the spring body 9. 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.

  In addition, the hook metal fitting 4 has a proximal end shaft portion 8 pivotally attached to the skirting board main body 2 so that the inclination angle of the skirting board main body 2 changes as shown in FIG. The hook metal fitting 4 can always be positioned horizontally so that the leg pillar Ab of the building frame A can be securely hooked and fixed. It should be noted that the mounting position of the hook metal fitting 4 is slightly shifted up and down on the left and right sides of the baseboard body 2, and when the baseboard 1 is attached continuously to the temporary scaffolding as shown in FIG. 1 hook metal fittings 4 are designed not to interfere with each other.

  Further, as shown in FIG. 6, the hook metal fitting 4 is formed so as to fit within the thickness width L of the skirting board main body 2 when rotated to a position substantially parallel to the skirting board main body 2. For example, when the skirting board 1 is transported and stored, the hook metal fitting 4 is designed so that it can be stably stacked without obstructing.

  Thus, when the scaffolding skirting board 1 is attached, the slits 5 of the respective locking metal fittings 3 at both ends of the baseboard 1 are inserted and locked onto the respective locking clamps Ba at both ends of the scaffolding board B. Next, the skirting board main body 2 is turned to the side of the pedestal Ab with the shaft body 6 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 of the pedestal Ab. Subsequently, after the hook metal fitting 4 is pulled to the side of the skirting board body 2 against the urging force of the spring body 9, the hook part 7 is rotated until the hook part 7 is in a substantially horizontal position to open the opening of the hook part 7. It is made to oppose the pedestal Ab. Then, when the hook metal fitting 4 is released from this state, the hook metal fitting 4 is shortened inward of the skirting board main body 2 by the restoring force of the spring body 9, and the hook portion 7 is caught by the leg pillar 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. 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.

  On the other hand, when the skirting board 1 is transported or stored, the hook metal fittings 4 at both ends of the skirting board main body 2 are rotated and positioned so as to be substantially parallel to the skirting board main body 2. At this time, the hook metal fitting 4 is formed so as to be within the thickness width L of the baseboard body 2, and the hook metal fitting 4 can be stacked stably without being bulky without being in the way. It is preferable that there is no fear of collapse during transportation and storage.
