Description

Safety rope fixing mechanism for coupling a clamp}

The present invention relates to a technology for fixing a safety rope, and more particularly, a clamp for fastening a safety rope using a clamp for a beam or a pipe installed on a vertical member for supporting a structure to securely and quickly bind the safety rope. It relates to a rope fixing mechanism.

In general, in a construction site, a scaffold is installed so that a worker can move and work at a height above a certain height, and a scaffold is installed here to help the transport of building materials or the safe movement of the worker, wherein the scaffold is in vertical and horizontal directions After forming a frame by crossing pipes with It is installed vertically, and the horizontal structure is coupled to the post pipe by using a connecting clamp. 0111220, etc. are introduced.

In addition, when constructing structures such as bridges or high-rise buildings, or in the process of building or building large structures such as ships, it is necessary to mount components up to a considerable height from the ground or perform various tasks such as processing and painting. Steel plate or H-beam is used, and a safety net to prevent damage from falling objects during work is also required. It is to be, the beam and the beam clamp is used on one side of the two beams spaced apart in order to fix the parapet for fall prevention built between the beam, and such a beam clamp is introduced in Patent Publication No. 10-2015-0022502.

On the other hand, a safety rope may be installed to prevent a fall of a worker who moves while maintaining a certain height separately from the scaffold installed between neighboring pipes through the clamp for the pipe or beam. In this case, both ends of the safety rope are As in Utility Model Registration No. 20-0119386 or Patent Registration No. 10-0726445, a coupling hole is machined on the coupling surface of the beam or a knot is made by using a separate tightening mechanism and wound around the pipe to bind it. .

However, as described above, when both ends of the safety rope are wound on the pipe or a coupling hole is machined on one side of the beam and bound here by a knot method, it takes a lot of time to install, as well as a coupling hole in a part of the structural material. There has been a problem in that the durability of the structural material is lowered due to the processing of the material, and when the coupling part is not sufficiently tightened, the knot is loosened or loosened, which causes a serious problem in that the safety rope does not function properly.

Furthermore, if the safety rope bound between adjacent pipes is loosened due to seasonal influences or due to on-site circumstances such as inclination of a specific structure, it is troublesome to dismantle and re-bond the safety rope bound to the pipe while stopping the work However, this re-bonding work was something that could not be neglected because it was a problem directly related to the life of the worker.
