Description

Scaffolding pipe clamp assembly

technical field

The present invention relates to a clip assembly for scaffolding pipes, and more particularly, to a clipping assembly for scaffolding pipes, which improves the structure and connection of a clip for fixing the scaffolding pipes arranged in a crosswise manner.

Background technique

The so-called scaffolding refers to the construction of buildings, bridges and other civil engineering and architectural structures, in order to set up a safety net to prevent the support molds used to construct the structure or the external construction work passages, as well as foreign objects or work tools. Scaffolding tubes made of metal materials that are installed at a certain interval from the vertical direction and the horizontal direction are called scaffolding, and the scaffold tubes are tied and fixed to each other using clip components.

The structure of the existing clip assembly includes: a pair of main bodies and a pair of main bodies arranged opposite to each other on both sides, the interior is curved, and the two ends are respectively provided with a first hinge and a second hinge; one end is rotatably connected to the main bodies; The first hinge is curved inside, and the other end is provided with a cover and a twisting groove; one end is rotatably connected to the second hinge of each main body, and the nut is screwed on the other end by thread, and then inserted into the screw of the cover. Knot grooves are twisted bolts. That is, a pair of clamps rotatably face the combined structure.

According to the technique disclosed in Korean Patent Office Laid-Open Patent Publication No. 10-2014-0020584 (Prior Document 1) "Anti-slip jig for scaffolding pipe" of this type of clip assembly, when constructing a temporary installation, that is, a scaffold, many jigs are used. The pipes are bound in the form of crossing each other, and in order to solve the phenomenon that the pipe slips on the fixture due to the shear force transmitted to the multiple pipes that are cross-connected when the external force or the scaffolding is overstressed during construction, the pipe is provided with an insert. There are insertion bumps on the base of the fixture where the pipes are bound, which are inserted into the insertion holes of the pipes to resist the shearing force acting on the multiple pipes that are cross-connected to each other, thereby preventing the pipes from slipping and further preventing the structure of the scaffolding. Deformation to ensure the safety of the scaffolding.

Korean Patent Office Registered Patent Gazette No. 10-1582617 "Clamp for Scaffolding Pipe" (Prior Document 2) once disclosed a technology that adds a safety function to prevent the clamp from sliding down or deflecting to one side due to load or impact. phenomenon, thereby preventing the risk of safety accidents and ensuring safety.

However, the clip assemblies of the prior documents 1 and 2 are composed of lids hinged and rotated with the existing main bodies facing each other, and the structure formed by screwing the other side of the main body and the lid with bolts needs to be screwed on the scaffolding pipes respectively. Therefore, the construction is cumbersome and inconvenient.

In addition, the existing clip assembly is installed to press and rotate the main body with a rotating support shaft, and the strength of the hinge part connecting the main body and the cover is weak, so the load it can bear is limited to about 1.5 tons, and when it cannot bear the load above it, Large-scale accidents such as hinge breakage may occur.
