Description

Clamp assembly for scaffold tube

Technical Field

The present invention relates to a scaffold tube clamp assembly, and more particularly, to a scaffold tube clamp assembly which is capable of easily improving the structure and connection of clamps for fixing scaffold tubes arranged in a crossing manner.

Background

The scaffold is a scaffold in which scaffold tubes made of a metal material are attached to each other with a constant interval in the vertical and horizontal directions in order to provide a safety net to prevent a support mold for constructing a structure, an external construction work tunnel, foreign matter or a work tool from dropping during work, and the scaffold tubes are bound and fixed to each other by using a clamp assembly.

The structure of the existing clip assembly includes: a pair of main bodies which are oppositely arranged at two sides, the inner parts of the main bodies are curved, and a first hinge and a second hinge are respectively arranged at two ends of the main bodies; a first hinge with one end rotatably connected with each main body, the inner part of the first hinge is curved, and the other end of the first hinge is provided with a cover of a twisting groove; and a second hinge having one end rotatably coupled to each of the bodies, and a nut threadedly engaged with the other end to be inserted into the screw engaged in the engaging groove of the cap. That is, a pair of clamps are rotatably coupled to face each other.

According to the technology of the clamp assembly disclosed in korean patent office laid-open publication No. 10-2014-0020584 (prior document 1) "anti-slip clamp for scaffold tubes", when a scaffold as a temporary installation object is constructed, a plurality of tubes are bound in a cross form by using a clamp, and in order to solve a phenomenon that the tubes slide on the clamp due to a shearing force transmitted to the plurality of tubes cross-connected when an external force or a scaffold is excessively stressed during construction, insertion holes are formed in the tubes, insertion projections are formed on a base of the clamp on which the tubes are bound, and are inserted into the insertion holes of the tubes to resist the shearing force applied to the plurality of tubes cross-connected, thereby preventing the tubes from sliding, further preventing structural deformation of the scaffold, and ensuring safety of the scaffold.

Korean patent office registration No. 10-1582617, "scaffold tube jig" (prior document 2) has disclosed a technique of increasing a safety function to prevent a phenomenon that the jig slips or is inclined to one side due to a load or an impact, etc., thereby preventing a risk of a safety accident and securing safety.

However, the clip assemblies of prior art documents 1 and 2 are constructed by the covers hinged to the main body facing each other, and the other sides of the main body and the covers are screwed by bolts, respectively, to the scaffold tube, which is cumbersome and inconvenient to construct.

Further, in the conventional clip assembly, since the main body is rotatably pressed by the rotary support shaft, the strength of the hinge portion for coupling the main body and the cover is weak, and thus, the load applied thereto is limited to about 1.5 tons, and when the load is not applied thereto, a large accident such as breakage of the hinge portion occurs.
