Abstract

(57) [Summary] [Purpose] To provide a handrail exclusive tool for reducing the labor and cost of installing the handrail of a scaffold for construction. [Structure] Attaching a slide part for expanding and contracting to the core pipe, attaching a mounting part consisting of U-shaped parts and bolts, and a hinge for freely opening and closing the mounting part Is characterized by.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This utility model is a handrail tool that is used at the end of building frame scaffolds and bends.

[0002]

[Prior art and drawbacks]

 In the past, when a handrail was attached to the curved part of the scaffold, a steel pipe was fixed by a clamp or a fastener such as a capra, so work efficiency was extremely poor. When attaching a handrail to the end of the frame scaffold, there is a dedicated handrail part for the 900mm width and 1200mm width building frames, but there is a dedicated handrail part for the 600mm width building frame. There was no such thing, and timbers were tied together with a numbered wire, so the work efficiency was still poor.

[0003]

[Problems to be solved by the device]

 When assembling the scaffolding, the labor required to attach the handrails to the ends of the scaffold and the bending part is reduced, the storage space is reduced, and the transportation cost is reduced.

[0004]

[Means for Solving the Problems]

 The slides on both sides of the core pipe shown in Fig. 1 are provided for expansion and contraction so that the length can be reduced to 600 mm at the shortest and the maximum length can be extended and contracted to 1200 mm. I decided to do it. The present invention is a handrail tool having the above configuration.

[0005]

[Action]

 The handrails will be fixed to the building frame or the building made of steel pipes with the bolts. With the above-mentioned usage, it can be used for both frame scaffolding with a construction frame of 600 mm width to 1200 mm width, and with the function of the hinge, it can be mounted at various angles.

[0006]

[Effect of device]

 From the above, the present invention makes it possible to easily attach a handrail to a 600 mm-wide building frame, and also to use it as a handrail for the curved part of the scaffold. Due to the above effects, steel pipes, fixtures such as clamps, square bars, wire rods, etc. were used for handrails in the past, but the handrail tool of the present invention simplifies the work process. And, you can achieve cost reduction.
