Description

[0001]
BACKGROUND OF THE INVENTION
[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.
[0002]
[Prior art]
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.
[0003]
[Problems to be solved by the invention]
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.
[0004]
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.
[0005]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the scaffolding skirting board of the present invention, an inverted U-shaped locking bracket that is locked to the locking clamps of the scaffolding plate at the lower ends of both side surfaces of the baseboard body is provided. It is characterized in that it is pivotally attached to the upper end of both side surfaces of the skirting board main body, and clamps for clamping the pedestal of the building frame are attached.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
According to the baseboard for scaffolding according to the present invention, the lower end of the baseboard is engaged with the anchoring clamp of the scaffolding board to integrate the baseboard and the scaffolding board. First, an inverted U-shaped locking bracket pivotally attached to the lower ends of both side surfaces of the skirting board body is inserted into the locking clamp of the scaffolding board from above and locked, and the lower edge of the skirting board body is the upper surface of the scaffolding board. It is placed so as to be close to or in contact with. Next, rotate the skirting board body toward the pedestal side of the building frame with the fixed locking bracket as a fulcrum, and tilt it until the upper edge of the skirting board comes close to or abuts the pedestal. The pedestal is clamped by the clamp fittings attached to the upper end of the bracket, and the attachment is completed.
[0007]
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.

【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0009]
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 2 shows a temporary scaffolding in which a brace C is hooked on the scaffolding board B. A scaffolding baseboard 1 of the present invention is attached around the scaffolding 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. A locking bracket 3 for locking onto the clamp Ba is provided, and a clamping bracket 4 for clamping the pedestal Ab of the building frame A is provided at the upper ends of both side surfaces 2a of the skirting board main body 2, respectively.
[0010]
3 and 4 are enlarged views of the main part, and the locking metal fitting 3 is an inverted U-shaped metal fitting having a slit 5 having a predetermined width, and is parallel to both side surfaces 2a of the baseboard body 2. FIG. The upper end portion is pivotally attached to both side surfaces 2 a 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. 4, the slit 5 can be inserted into the base end portion of the locking clamp Ba from above and locked. I am doing so. And if the latching metal fitting 3 is latched and fixed, as shown in FIG. 4, the baseboard main body 2 will be able to turn to the pedestal Ab side with the shaft body 6 as a fulcrum.
[0011]
Further, the holding metal fitting 4 comprises a substantially U-shaped holding body 7 for holding the leg pillar Ab of the building frame A, and a holding piece 8 pivotally supported at one end of the holding body 7. The other end portion of the sandwiching body 7 is provided with a spring pin (not shown) and is provided with a locking pin 9 that is urged downward, and an inclined surface 10 is provided at the tip of the locking pin 9. On the other hand, a through hole 11 having a size capable of inserting the locking pin 9 is formed in the free end portion of the clamping piece 8. Then, when the holding piece 8 is rotated to the holding position in a state where the leg column Ab is fitted in the U-shaped groove portion of the holding body 7, first, the free end portion of the holding piece 8 contacts the inclined surface 10 of the locking pin 9. When the abutment piece 8 is further abutted and the clamping piece 8 is further rotated, the locking pin 9 is retracted upward against the urging force of the spring body. Then, if the clamping piece 8 is further rotated from there to a position where the locking pin 9 faces the through hole 11 of the clamping piece 8, the locking pin 9 is brought into the through hole 11 of the clamping piece 8 by the restoring force of the spring body. It is configured to penetrate and maintain the clamping state. In this way, it is possible to securely hold it while being a simple operation suitable for high-altitude work, and does not require an installation tool or the like, and is excellent in installation workability.
[0012]
And this clamping metal fitting 4 is fixed to one end part of the support material 12 which is a plate material, while the other end part of the support material 12 can be freely rotated by the shaft body 13 at the upper end parts of the both side surfaces 2a of the skirting board body 2. As shown in FIG. 4, the pedestal Ab of the building frame A can be securely clamped by the clamping bracket 4 even if the inclination angle of the skirting board main body 2 changes. In addition, the mounting direction of the support material 12 is changed on the left and right sides of the baseboard body 2, and one of them is attached so that one side is upward and the other side is downward. When the skirting boards 1 are continuously attached, the height positions of the sandwiching metal fittings 4 of the respective baseboards 1 are shifted vertically so that the sandwiching metal fittings 4 do not interfere with each other.
[0013]
When the clamping metal fitting 4 is clamped to the pedestal Ab of the building frame A, as will be described with reference to FIGS. 5 to 7, first, the support material 12 with the clamping metal fitting 4 is attached to the pedestal Ab. The pedestal Ab is fitted into the U-shaped groove portion of the sandwiching body 7 until it becomes substantially parallel (a). Next, when the clamping piece 8 is rotated in the clamping direction, the free end portion of the clamping piece 8 comes into contact with the inclined surface 10 of the locking pin 9 so that the locking pin 9 resists the biasing force of the spring body. The holding piece 8 can be rotated to the holding position (b). When the holding piece 8 is further rotated to hold the pedestal Ab, the locking pin 9 faces the through hole 11 of the holding piece 8, and the locking pin 9 is moved by the restoring force of the spring body. It penetrates and is fixed to the through-hole 11 (c). When releasing the clamping, the upper end of the locking pin 9 is held by hand and pulled upward against the urging force of the spring body, and then the clamping piece 8 is rotated to the release position (a). If so, it can be released.
[0014]
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, the support member 12 with the holding metal fitting 4 is rotated to fit the U-shaped groove portion of the holding body 7 of the holding metal fitting 4 into the leg pillar Ab. In this state, when the holding piece 8 of the holding metal piece 4 is rotated to the holding position, the locking pin 9 automatically moves in and out to penetrate the through-hole 11 of the holding piece 8 and maintain the holding state.
[0015]
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 scaffolding board B and the skirting board 1 are integrated with each other, so that the scaffolding board B is not easily shifted to the left and right, and even if it is shifted to the left or right at any time, it is integrated with the scaffolding 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.
[0016]
In the above embodiment, the holding metal fitting 4 has been shown to be clamped by a simple operation. However, the present invention is not limited to this structure, and other clamps that can securely clamp the pedestal Ab of the building frame A are provided. Means can also be employed.
[0017]
【The invention's effect】
