Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower casting structure technology, specifically to an assembly structure for casting the bottom platform on a wind turbine tower. Background Technology

[0002] When constructing wind turbine towers using an enlarged slab foundation structure, after pouring the base portion below the reference plane, it is also necessary to pour the foundation structure located above the base. Since electrical equipment to be installed inside the wind turbine tower needs to be placed on the foundation, sufficient area needs to be reserved on the poured foundation for installation. To avoid interference with these areas during pouring, it is necessary to pre-set molds and corresponding embedded parts at the corresponding locations. Currently, the placement of these devices is mostly handled simultaneously when tying the concrete reinforcement, which makes it difficult to ensure the positional accuracy of the molds and embedded parts during installation and is also prone to interference with the reinforcement. This is the main problem that needs to be solved at present. Utility Model Content
