The post-expansion anchor is also a kind of mechanical anchor. Usually, during use, the durability and fatigue resistance of the post-expansion anchor are greatly improved due to the joint participation of the mechanical locking key and the structural adhesive. The role of planting glue in the adhesive mold reaming bolt system is very important, because qualified planting glue can help the reaming bolt to be completely safe and functional. The steel bars are embedded in the concrete and there is a reliable connection between them. Concrete has an effective bonding force for reinforcement, and the two form an overall common force.
The post-anchoring phase has simple structure and flexible operation, and is suitable for traditional pre-embedded anchoring. Initially, post-installation equipment was limited to the reinforcement of the original building. With the continuous promotion, use and development of construction technology, the performance of post-anchoring technology in new structures is not satisfactory. With the rapid development of the construction industry, there are more and more types of new projects, reinforcement and renovation projects. The traditional embedded steel reinforcement method can no longer meet people's needs. The emergence of post-anchoring technology is particularly important.
