Description

Reinforcing bar anchor that concrete construction used

Technical Field

The utility model relates to the technical field of civil engineering, in particular to a steel bar anchoring device for concrete construction.

Background

The steel bar in the reinforced concrete structure can be stressed, and the steel bar is mainly based on the bonding and anchoring effect between the steel bar and the concrete, so that the anchoring of the steel bar is the stressed foundation of the concrete structure. If the anchoring fails, the structure will lose its load-bearing capacity and thus cause structural failure. The anchorage of the reinforcing steel bars refers to the fact that the stressed reinforcing steel bars of the components such as beams, plates, columns and the like extend into the support or the foundation.

The commonly used steel bar anchoring device is a circular anchoring plate with internal threads, and the steel bar is in threaded connection with the circular cap hoop plate by processing external threads matched with the steel bar on the steel bar. The method not only requires the steel bar to be preprocessed, increases the prefabrication cost of steel parts, but also has higher requirement on the matching degree of the prefabricated thread specifications of the steel bar and the anchoring plate, namely, the steel bar and the anchoring plate are required to be highly matched in production and processing, so that the production and management work becomes complicated. Therefore, in order to solve such problems, we propose a reinforcing bar anchoring device for concrete construction.
