Abstract

An object of the present invention is to provide a steel fabric board lateral slip prevention fitting for a scaffold using a wire rope that can improve work efficiency and reduce costs by repeated use.
When an external force is not applied, a shape memory coating wire rope having a circular shape wound around a horizontal member 10 of a building frame is attached to a wire rope portion 2 of the shape memory coating wire rope, all screw bolts 5 and a nut. 4 is connected by a joint metal fitting 7, the wire rope portion 2 of the shape memory coating wire rope and the cotter bolt 6 are connected by the joint metal fitting 7 to the other end, and a flat portion in which the central portion is a circular shape of the horizontal frame 10 of the building frame. In the steel plate 3, both ends are horizontal and there is a hole through which the entire screw bolt 5 is inserted on one flat steel plate surface. The nut 4 is tightened from the side through which the full screw bolt 5 is passed and the flat steel plate 3 is removed. The notch through which the bolt of the cotter bolt 6 passes is bent from the long side toward the center of the flat steel plate 3 and cut into an L shape.

Description

The present invention relates to a steel cloth board lateral slip prevention fitting for a scaffold.

The gap between floor materials on the work floor of a conventional temporary scaffold is determined by the occupational safety and health regulations to be 3 cm or less, but the gap between the first two steel cloth boards on the work floor of the building frame is 3 cm or less. Even if it was laid on the floor, when working on the work floor, a large number of people moved around the work floor, and the steel cloth board gradually shifted to the side and the gap became more than 3 cm.

Nitto Rail Co., Ltd. Annealing wire, processing wire

Conventionally, there are the following drawbacks.
To prevent the steel cloth board from slipping, the claw fittings of adjacent steel cloth boards were tied and fixed with a wire to prevent the lateral displacement of the steel cloth board. Although it was necessary to tighten the wire through the gap between the claws on the fabric board, it was a manual operation and the work efficiency was poor, and the wire was also disposable.
In view of the above-described conventional drawbacks, the present invention is intended to provide a steel cloth board lateral slip prevention bracket for a scaffold using a wire rope to improve work efficiency and reduce costs by being able to be used repeatedly.

    To achieve the above object, the present invention provides a wire rope of a shape memory coated wire rope at one end of a circular shape memory coated wire rope wound around a horizontal frame of a building frame when no external force is applied. All screw bolts and nuts are connected with a joint bracket, and the other end is connected with a wire rope of a shape memory coating wire rope and a cotter bolt with a joint bracket. Both ends are horizontal and there is a hole through which all screw bolts pass on one flat steel plate surface. The nut is tightened from the end of the flat steel plate that passes through all screw bolts, and the other flat steel plate surface has a cotter bolt bolt. The cut that passes is bent from the long side toward the center of the flat steel plate, and is cut into an L shape. For this reason, a steel cloth board lateral slip prevention bracket using a wire rope is installed beside the steel cloth board claw bracket, and the cotter bolt is inserted from the side of the flat steel plate and moved so that the cotter portion of the cotter bolt does not come off. Then, by tightening the nut of the other full screw bolt, the shape memory coating wire rope and the flat steel material tighten the horizontal frame of the building frame, and the claws of the steel cloth board hit the steel cloth board lateral slip prevention fitting, and the steel cloth The steel cloth board side slip prevention metal fitting of the scaffold using the wire rope which has a function which prevents a board from shifting is constituted.

As is clear from the above description, the present invention has the following effects.
(1) By adopting a shape memory coated wire rope and a steel plate as the fastening member, the weight of the metal fitting is reduced.
(2) The manual work by a skilled worker who cuts the wire and tightens the wire through the gap between the metal fittings on the steel cloth board is eliminated. Even if an inexperienced worker increases the work efficiency, the nut is tightened with an electric tool to prevent the lateral displacement of the steel cloth board.
(3) Since the steel cloth board side slip prevention fitting of the scaffold using a wire rope with a nut can be attached and detached, it is not necessary to perform on-site processing like a wire and can be used repeatedly without being disposable.
