Description

Precast beam reinforcing bar anchor structure Technical Field The utility model relates to the technical field of constructional engineering, in particular to a precast beam steel bar anchoring structure. Background The reinforced bars in the reinforced concrete structure can bear force, and the anchoring of the reinforced bars mainly depends on the bonding anchoring effect between the reinforced bars and the concrete, so that the anchoring of the reinforced bars is a foundation of the stress of the concrete structure, if the anchoring fails, the structure loses bearing capacity and the structure is damaged, and the anchoring of the reinforced bars refers to the fact that the stressed reinforced bars of members such as beams, plates and columns extend into a support or the foundation; However, most of the existing precast beam steel bar anchoring structures are connected with steel bars at the top ends of the upright columns in a straight anchoring mode, the anchoring reliability of the structure is insufficient, the anti-seismic performance is weak, the existing precast beam steel bar anchoring structures are dependent on pure bonding anchoring, and the technical scheme provided by the utility model with the application number of CN201980652D is found after searching, so that the problems are solved. Disclosure of utility model The utility model aims to provide a precast beam steel bar anchoring structure, which solves the problems that in the prior art, the precast beam steel bar anchoring structure is connected with steel bars at the top ends of upright posts in a direct anchoring mode, the anchoring reliability of the structure is insufficient, the anti-seismic performance is weak, and the structure depends on pure bonding anchoring. In order to achieve the purpose, the precast beam steel bar anchoring structure comprises a precast beam, wherein the left end and the right end of the precast beam are fixedly connected with a first high-strength steel bar, the first high-strength steel bar adopts a twice 90-degree bent anchor, the left end and the right end of the precast beam are fixedly connected with a second high-strength steel bar, and the second high-strength steel bar adopts a once 90-degree bent anchor. According to the precast beam steel bar anchoring structure, a high-strength steel bar III is fixedly connected between the high-strength steel bar I and the high-strength steel bar II. According to the precast beam steel bar anchoring structure, the lower end of the high-strength steel bar III is fixedly connected with the upright post I. According to the precast beam steel bar anchoring structure, the right end of the precast beam is fixedly connected with the second upright post. The scheme has the beneficial effects that the anchoring reliability can be remarkably improved and the dependence on pure bonding anchoring can be reduced by arranging the first high-strength reinforcing steel bar which can be bent for one time by 90 degrees and the second high-strength reinforcing steel bar which can be bent for two times by 90 degrees at the left end and the right end of the precast beam. Additional aspects and advantages of the utility model will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model.
