[0002] Precast concrete connection structure is a technology commonly used in construction projects. It mainly refers to concrete components pre-manufactured in the factory, which are transported to the site and then combined into an overall structure through a certain connection method.

[0003] During the construction process, the tower is set into a ring shape, and each ring is divided into four prefabricated pieces, which are then assembled and connected on site using prestressed bent bolts and epoxy structural adhesive. However, during the assembly process, it is difficult to align it in one go. During multiple movements and alignments, the epoxy structural adhesive at the connection is easily stained and falls off, resulting in uneven coating of the epoxy structural adhesive, affecting the fixing effect. In the process of assembling the upper and lower rings, only positioning pins and epoxy structural adhesive are used for connection, and the connection is not stable enough. Utility Model Content
