Description

Installation structure of work scaffolding {Structure For Setting Scaffold}

The present invention relates to a scaffold for work, and more specifically, to provide a passage to move between upper and lower layers, but relates to an installation structure of a scaffold for work, provided with an opening and closing foot opening and closing in a slide manner.

A scaffold for work, also known as scaffolding, is installed for the building's new construction or remodeling site to work on the exterior walls of the building. In the past, panels made of plywood were widely used, but recently, steel scaffolds with excellent rigidity, safety and durability are widely used.

These work scaffolds are supposed to be installed with pipes in the form of pipes called ashibas outside the building. Working scaffolds are installed at predetermined intervals in the vertical direction. In actual work, there is a need for the worker to move up and down on the work platform. Every time the floor is moved up and down, it is very cumbersome to go into the building and use the stairs of the building, so in the past, a passage for up and down has been created for the work platform.

6, the passage for vertical movement may be made by opening and closing some of the multiple unit scaffolds 100, 100 ′ and 110 as illustrated in FIG. 6. The passageway of the conventional working scaffold (100,100 ', 110) was provided by allowing the specific working scaffold (110) to be hinged and lifted up (see Republic of Korea Utility Model Registration No. 20-2006-0017601). However, in this case, since the work footrest 110 is flipped and left open, it has often become a very dangerous factor not only for the parties but also for other workers. It was also inconvenient to open and close the scaffold 110 for this operation.
