Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffolding board for suspension scaffolding or a scaffolding board for frame scaffolding used for construction work such as plant construction, bridge construction and special construction.

[0002]

2. Description of the Related Art In general, a suspension scaffold used for plant construction, bridge construction, or painting work of these, suspends a horizontal member from above, and hooks on the horizontal member through a scaffold plate through a hook. It is usual to construct a scaffold and carry out construction work and painting work on this scaffold board.

On the other hand, a frame scaffold used for exterior construction of a building comprises a frame body composed of a horizontal bridge material erected between the erect standing on the ground, and a scaffold via a hook on the horizontal bridge material. It is common to erection a board and perform the necessary work on this scaffolding board.

In the above-mentioned suspension scaffolding or frame scaffolding, there is also used one in which a scaffold plate is simply erected on a horizontal member via a hook, but in order to prevent the hook from coming off from the horizontal member due to vibration or the like. It has become common to provide a stopper mechanism facing the hook, and hold the horizontal member between the hook and the stopper mechanism to prevent the hook from coming off during use.

The above-mentioned conventional suspension scaffolding or frame scaffolding utilizing the scaffolding plate has the following problems.

First, since the scaffolding plate is usually formed in an elongated shape in order to reduce the weight, even if a plurality of scaffolding plates, for example, two scaffolding plates are arranged side by side on a horizontal member, the scaffolding plates are arranged between the scaffolding plates. There is definitely a gap.

For this reason, there is a danger that nails, bolts, tools, small building materials, etc. on the scaffolding plate will drop downward through this gap.

Secondly, the scaffolding plates are arranged continuously also in the longitudinal direction, but in this case, each scaffolding plate is formed by hooking the hooks extending from the front and rear ends on the horizontal member. , A gap corresponding to the width of the two hooks is formed between the scaffold plates adjacent to each other in the front and rear, and there is a danger that the tool or the like on the scaffold plate will drop downward from this gap in the same manner as described above.

For this reason, the present applicant has recently developed a scaffolding board in which a gap is not generated between the scaffolding boards when a large number of scaffolding boards are arranged in the horizontal and vertical directions.

In this scaffolding board, skirting boards are erected at both left and right ends of the board body, and a plurality of notches are provided at both front and rear ends of the board body, so that gaps are generated on both sides of the board body by the skirting board. In addition, the notches of two scaffolding plates adjacent to each other in the vertical direction are fitted to each other so as to eliminate a gap at the joint portion of the scaffolding plates.

[0011]

However, if there is no gap between the scaffold plates as described above, the safety of dropping tools and tripping of workers can be achieved, but there are the following problems. .

That is, at the time of assembling and disassembling the suspension scaffold, the frame scaffold, it is necessary to attach and detach the hook of the scaffold plate to the horizontal member, but in this case, the stopper mechanism is retracted or released in advance to make the hook the horizontal member. It must be ready for plugging in and out.

However, the releasing operation of the stopper mechanism needs to be performed from above the suspension scaffolding plate, and can be performed from below the scaffolding plate on the frame scaffolding, but it must also be performed from above for work efficiency.

The releasing operation of such a stopper mechanism is as follows.
In the above-mentioned conventional scaffold with a gap, it was possible to perform from above the scaffold board using this gap, but in the newly developed scaffolding without suspension using suspension scaffolding and frame scaffolding This operation is difficult to perform when the vehicle is on the scaffolding plate, especially on the scaffolding plate, and the work of assembling and disassembling the scaffolding may be significantly reduced.

Therefore, an object of the present invention is to provide a scaffolding board which can be easily locked or unlocked by a stopper mechanism below the scaffolding board or from above the scaffolding board and lifted up from the cross member. Is.

[0016]

In order to achieve the above object, a scaffolding plate according to the invention of claim 1 is a horizontal plate main body and is detachably attached to a horizontal member provided at both front and rear ends of the plate main body. A plurality of hooks engaged with the hook, and an arc-shaped stopper member movably provided at the lower part of the hook by its own weight so as to sandwich the horizontal member between the hooks,
One end of the hook pinching release member is locked to the stopper member, and the other end is made to face the upper opening of the plate body so as to be able to move up and down.

Further, the scaffolding plate according to the invention of claim 2 is

And a hook pinch releasing member which is partially locked to the upper end of the stopper member so that the stopper member can be moved and is horizontally operable from the upper opening of the plate body. Is urged by the elastic member in the hook pinch release preventing direction so that the hanging through hole provided in the hook pinch release member faces the upper opening when the pinch pinch is released.

In the scaffolding plate according to the invention of claim 3, a part of the scaffolding plate is engaged with the stopper member so that the stopper member can be moved, and the hook is provided so as to be vertically rotatable from the upper opening of the plate body. A holding release member is provided, and a hanging notch is provided in the hook holding release member.
