Description

Binding apparatus for scaffold operation pedal

Technical Field

The present invention relates to a binding apparatus for scaffold operation steps, which is required to secure a scaffold tube or a scaffold to a work space on a construction site or to secure a scaffold to a scaffold tube or a scaffold.

Background

In various construction sites such as construction and ship building, where there is a risk of falling or falling, it is common to provide a work foot board (foot board) for safe passage and construction of workers and the like.

In the conventional operation pedal, an operation pedal made of a quadrangular plate is transversely arranged on a horizontally fixed bracket for construction.

However, the conventional work foot plate is not practical because it is constructed by binding the front and rear ends of the foot plate to the scaffolding pipe or the scaffold with a binding tool such as a wire, and the binding tool is bound one by an operator for the construction of the binding tool, so that the dismantling work is complicated, and the connecting tool used once cannot be used again.

And the front and rear ends are arranged between the front and rear operation pedals through the annular clamping device, so that a space is generated and potential safety hazards exist.

According to korean patent office laid-open publication No. 10-2005-0120607, there is disclosed a technique of fixing a safety pedal by inserting U-bolts into binding holes formed at both sides of the pedal at a predetermined interval and fixing the safety pedal to a scaffold tube or a bracket.

However, in the conventional technology, in order to fix the safety step, the U-bolt is tied to the scaffold tube or the bracket at the lower part side and then fixed by the nut at the upper part after being hooked, so that there is a problem that the construction and the disassembly work are complicated and the time required is long.
