Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a suspended scaffold, and particularly to a chain-suspended type of suspended scaffold used for high-altitude work near the ceiling.

[Background of the idea]

A conventional chain-suspended scaffolding includes a plurality of chains that are suspended from locking portions that are fixed in advance to a ceiling or the like, and a work floor that is attached to the chains.

However, in the conventional suspended scaffolding, the corner of the work floor is locked to a chain, and the locking part protrudes outward from the work floor. interfered with the connection and I was unable to connect. For this reason, conventional suspended scaffolding cannot expand the working floor area, and when work areas are scattered, it is necessary to suspend a suspended scaffold at each work area, resulting in problems such as poor work efficiency. It was hot.

Furthermore, in Japanese Patent Publication No. 57-53504, a notch 63 is formed on the side edge of the work floor 6, and the chain 5 is inserted into the notch 63, and the chain 5 is locked to the work bed 6 by a locking member 62. However, the chain 5 and the locking member 62 are prevented from protruding from the front and rear edges of the work floor 6. However, when these scaffolds are arranged vertically and horizontally, the chains 5, 5, etc. are dispersed, increasing the number of chains, and this has the disadvantage that it is very inconvenient to use as a work floor.

[Purpose of invention]

The present invention was developed in view of these circumstances, and aims to provide a suspended scaffold that can connect adjacent work floors vertically and horizontally, and that is easy to use as a floor by reducing the number of chains. The purpose is

[Summary of the idea]
