Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hanging scaffolding fitting, and particularly to a hanging fitting for a scaffolding pipe.

[Prior Art] Conventionally, as shown in FIG. 4, a suspended scaffold has been constructed by winding a scaffold chain 2 around a scaffold pipe 1, and suspending the scaffold chain 2 through between scaffold boards 3 and 4.

[Problems to be solved by the invention] However, in the above suspension structure, since the spacing H ₁ between the scaffolding chains 2 is large, the scaffolding chains 2 cover the gap H ₂ between the scaffolding boards 3 and 4. It must be large enough to be inserted. For this reason, there is a risk that parts of the hanging fitting may fall through the gap _H2 , so it is necessary to close the gap _H2 to prevent falling objects for safety reasons. Therefore,
It took a lot of man-hours to close the gap. Furthermore, the work of winding the scaffolding chain 2 around the scaffolding pipe 1 was time-consuming and dangerous because the work was carried out at high places.

The purpose of the present invention was made in view of the above-mentioned drawbacks, and it is possible to reduce the gap between the scaffolding boards and prevent parts of the hanging fittings from falling through the gap without having to close the gap. Moreover, to provide a scaffolding pipe hanging fixture which allows the work of attaching a scaffolding chain to a scaffolding pipe to be carried out easily and quickly.

[Means for Solving the Problems] The scaffolding pipe hanging fitting according to the present invention includes a yoke having a pair of members formed so as to be able to open and close left and right around a fulcrum provided at the lower end. , the yoke has a scaffolding pipe clamp section at its lower part, a ring member to which a hanging chain is hooked at its upper part, and an intermediate aperture in which a scaffolding plate is arranged at a part connecting the upper and lower parts. The upper part of the yoke and the ring member are connected by a pin having a retaining means.

[Function] In the scaffolding pipe hanging fitting according to the present invention, the part of the yoke where the scaffolding boards are arranged is an intermediate narrowing part, so the gap between the scaffolding boards can be set smaller than the spacing between the hanging chains. Therefore, parts of the hanging fitting can be prevented from falling through the gap without having to close the gap. Furthermore, since a pin with easy-to-install locking means is used, chain hanging work at high places can be done easily and quickly. Therefore, safety is also improved. Furthermore, since the scaffolding chain is hooked through the ring so as not to damage the scaffolding chain, damage to the scaffolding chain can be prevented.

[Example] Hereinafter, details of the present invention will be explained using examples shown in the drawings.
