Description

[0001] Clamp assembly for scaffolding pipe [0002]

The present invention relates to a clamp assembly for a scaffold pipe, and more particularly, to a clamp structure for fixing a scaffold pipe installed in an intersecting direction and a clamp assembly for a scaffold pipe which is improved so as to facilitate the fastening.

In the construction of civil engineering and building structures such as buildings and bridges, it is necessary to support the formwork for constructing the structure, or to install a safety net to prevent foreign objects or work tools from falling during the work for external construction and work. And a clamp assembly is used for clamping and fixing the scaffold pipes to each other.

A conventional clamp assembly includes a pair of main bodies installed on both sides so as to be opposite to each other, a curved inner portion, and a first hinge and a second hinge at both ends; A cover hingedly coupled to the first hinge of each of the main bodies so that one end thereof is rotatable, the inside of the main hinge is formed in a curved shape and the other end thereof has a fastening groove; And a bolt rotatably fastened at one end to a second hinge of each of the main bodies and screwed to a nut at the other end and inserted into the fastening groove of the lid. That is, the pair of clamps are opposed to each other so as to rotate.
