[0002] At present, most prefabricated towers of mixed towers are in the form of full-straight, segmented and piece-by-piece types. The so-called piece-by-piece means that the cylinder section of the mixed tower frame is made up of multiple pieces and is fixed by grouting connection. However, the existing grouting-free dry-type prefabricated assembled mixed towers mostly adopt a combination connection method of embedded parts and bolts. This method has the problem of bonding slippage between the studs and concrete and partial detachment of concrete under repeated loads, thereby affecting the bearing capacity, and then causing large deformation in the later stage. It cannot be used for main load-bearing components with high seismic requirements and the problem that the internal and external segments are severely unevenly stressed and local plate damage is easy to occur.

[0003] To solve the above problems, the prior art patent (CN215566378U) discloses a wind turbine hybrid tower prefabricated tower section connection structure. Through embedded plates and pressing plates, the area of ​​the load-bearing part can be expanded, thereby avoiding the problem of bonding slippage between the bolts of the segmented anchoring part and the concrete and partial falling off of the concrete caused by the traditional fixing method, which in turn affects the overall bearing capacity and stability.
