Description

Technical Field

[0001] The invention belongs to the technical field of mixed tower construction moulds, and in particular relates to a prefabricated mould for a wind power generation mixed tower. Background Art

[0002] With the gradual consumption of global energy, wind power as a renewable energy generation technology has achieved unprecedented rapid development. As the most common construction structure of wind power generation equipment, the mixed tower is mainly a reinforced concrete structure or a steel tower structure. Both the reinforced concrete structure and the steel tower structure need to be prefabricated in the factory before the mixed tower is transported to the installation site to assemble multiple sections of the tower. Usually, the wall thickness and diameter of the wind turbine tower are designed to be very large, the diameter is usually more than 4 meters, and the height is generally more than 100 meters. The maximum diameter at the bottom is 11 meters, the minimum diameter at the top is 4 meters, and the height of each section varies from 3 to 4 meters. The wall thickness is more than 60 mm, and the height of each mixed tower section is 3 to 4 meters. With the increase in the height of the tower, the production cost and transportation cost are increased in disguise, and it is even limited by transportation conditions and cannot be transported on the road. For this reason, the mixed tower structure needs to consider the convenience of transportation when predicting, thereby increasing the transportation cost in disguise. In order to meet market demand, manufacturers currently have launched prefabricated assembled mixed tower molds, and the production of mixed tower molds has become an important factor in the development of wind turbine towers. The wind power tower cast using prefabricated assembled molds usually requires multiple pieces of steel formwork for assembly. The steel formwork assembly process is relatively complicated. The disadvantages of this method in the actual construction process are that the steel formwork is heavy, has a large radius and a large arc span, the prefabricated formwork is difficult to install, the mold assembly efficiency is not high, and it is difficult to assemble and adjust. When casting the tower structure, it is easy to open the outside of the mold, which will affect the demoulding efficiency of the tower mold. It is also difficult to disassemble the mold after casting.
