Description

[0001] APPARATUS OF FIXING FOOTING SCAFFOLDING [0002]

The present invention relates to a scaffolding fixture for scaffolding, and more particularly, to a scaffolding scaffold for high-altitude work, which can securely and quickly clamp the scaffolding installed to secure a work space and a walkway, To a pedestrian fixing device for a scaffold.

Generally, as a means for transporting various equipments and materials to work in an industrial field such as construction, construction, shipbuilding, etc., a steel pipe for temporary construction, which is a temporary structure, is installed, A method of putting a footstep in a work platform is becoming common.

The work scaffold installed on the steel pipe scaffold is a structure that directly affects the productivity of work. It is made of various standard steel materials passed the performance test. Especially, the scaffold used in the shipbuilding field and the high- We are innovating safety culture through standardization of safety standards.

The work foot scaffold constituting the scaffold is fixedly installed on a plurality of steel pipes. At this time, the work scaffold is tied with a wire to fix the scaffold to the steel pipe, but the workability is poor, .

Conventional patent No. 10-1016274 discloses a chief footrest which allows a pair of plates to be assembled together when necessary in a state where they are in contact with each other. The footrest is formed in a shape that can be engaged with the space of the tanned portion of the plate And a clamping member for clamping the pipe through the coupling hole of the bracket, wherein a threaded rod is formed on the upper end of the clamp, and a cylindrical fixing pin having a threaded hole is coupled laterally And the clamp handle is operated through the operation hole by engaging the clamp handle with the eccentric hole provided in the fixing pin so that the pipe wrapping the clamp is pulled by the eccentric hole so that each plate can be fixed firmly. A jig has been proposed.

However, in the conventional technique, since the clamp for wrapping the pipe is a hook, when the pipe is pulled by operating the clamp handle, the force is applied only to the portion where the hook is contacted, There is a problem in that the robustness and safety are poor.

Particularly, when the clamp handle is operated and the clamp surrounding the pipe is pulled upward from the fixed pin coupled to the eccentric hole, an eccentric stress is applied to the clamp having one hook structure, It is not easy to remove the clamp from the steel pipe due to the deformation or damage of the clamp.
