Recyclable rebar anchor pull ring and mounting support thereof

Abstract

The invention relates to the technical field of outer engineering construction, in particular to a rebar anchor pull ring of an overhang frame fixing steel beam and a matched device. The recyclable rebar anchor pull ring comprises a U-shaped ring, an upper bearing steel sheet, nuts, an embedded tube and a lower bearing steel sheet, wherein end portions of the U-shaped ring are provided with threads, the upper bearing steel sheet is connected onto the end portions of the U-shaped ring in a sleeved manner, the nuts are used for fixing the upper bearing steel sheet, the embedded tube is arranged in a floor slab and allows the U-shaped ring to penetrate, and the lower bearing steel sheet is connected onto the bottom of the U-shaped ring in a sleeved manner; the mounting support comprises a base, an extension rod and a normal-clamping clamp which are arranged from bottom to top, and a switching device is connected onto the clamp. The rebar anchor pull ring in the technical scheme is simple in structure, convenient to mount and dismount and can be recycled without damaging concrete.

Description

technical field [0001] The invention relates to the technical field of external frame engineering construction; in particular, it relates to a steel bar anchor pull ring and a supporting device for fixing a steel beam of a cantilever frame. Background technique [0002] In the construction of high-rise buildings, temporary cantilevered structures such as steel suspended scaffolding and tool unloading platforms are widely used. In order to fix the steel beams of these temporary cantilevered structures, it is usually necessary to pre-embed a one-time inverted U-shaped steel pull ring in the floor. , Extend the steel beam into the pull ring, and plug it tightly with a wooden wedge or steel wedge to fix the steel beam. Some construction companies also adopt the method of pre-embedding U-shaped steel bars, and then closing the opening with bolts and steel plates to form a pull ring.

AI Technical Summary

Problems solved by technology

[0003] The above two types of steel anchor pull rings are thick steel bars fixed in the concrete. During the use, the thick steel bars will be stressed for a long time, especially the dynamic load will cause extrusion damage to the concrete in direct contact. After the construction is completed, due to these The thick steel bar cannot be taken out, so it must be cut off by high-energy gas cutting, so that the subsequent floor treatment can be carried out normally. In this construction method, because the anchor ring of the steel bar can only be used once, a lot of steel is wasted. In addition It also increases the workload of construction and the difficulty of operation
