Self-detaching anchor at resting end of cantilever bottom beam for construction

Abstract

The invention relates to the technical field of self-detaching anchors, in particular to a self-detaching anchor at a resting end of a cantilevered bottom beam for construction. The self-detaching anchor comprises a built-in fixed block, two symmetrical outer surfaces of the built-in fixed block are fixedly connected with two fixed connecting tubes respectively, fixed connecting plates are arranged at ends of the fixed connecting tubes, screw penetrating slots are formed in the outer surface of each fixed connecting plate, the screw penetrating slots correspond to the position of the fixed connecting tubes, a first connecting bolt is inserted into each of the screw penetrating slots, the first connecting bolts are connected inside the fixed connecting tubes through screws, the fixed connecting plates are in the shape of a Z, and mounting slots are formed in one end of each fixed connecting plate. According to the invention, connection firmness of the whole is improved by the two oppositely arranged fixed connecting plates, and the anchor is endowed with an expansion function by expansion springs, so that the problem of offset of a resting point caused by bolt loosening after long-term use is avoided.

Description

technical field [0001] The invention relates to the technical field of self-detachment anchors, in particular to a self-detachment anchor at the resting end of a cantilevered bottom beam for construction. Background technique [0002] In the construction of contemporary high-rise buildings, external scaffolding is often erected in a cantilevered manner. Every 6 to 8 floors are a cantilevered floor. The cantilever beams connected to the floor are installed to disperse the load, and the safety of the scaffolding must be guaranteed. . Usually, during the construction of scaffolding, it is necessary to embed steel bars in the concrete layer, and then use the steel bars extending to the outside as support points. In this way, it is necessary to cut the external steel bars when dismantling the scaffolding, which is cumbersome, so the application of anchors is effective. Solved the problem of cutting external steel bars. [0003] The existing anchors only fixedly connect the conn...

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-detachable anchorage at the resting end of a cantilevered bottom beam for construction, which aims to solve the problem that the existing anchorage only performs fixed connection of the connectors on the upper layer of the concrete pouring layer, and the connection firmness needs to be improved. At the same time, the function is single and there is no function of expansion and tightening. During the long-term support process, it is easy to cause the problem of loosening of bolts and shifting of the resting point.
