The embodiment of the invention provides a connecting structure and manufacturing method of a tower drum section. The connecting structure comprises two or more tower drum divided pieces. Each tower drum divided piece comprises two first side end faces, each first side end face is provided with a plurality of connecting pieces, and the multiple connecting pieces are arranged at intervals in the length extending direction of the first side end faces. In every two adjacent first side end faces of the two corresponding adjacent tower drum divided pieces, one or more of the connecting pieces of one of the first side end faces are fixedly connected with the corresponding connecting pieces on the other first side end face correspondingly. According to the connecting structure of the tower drum section, hole channels do not need to be reserved in the top faces of the tower drum divided pieces, the manufacturing process of the tower drum divided pieces is simplified, and the structural strength of the tower drum divided piece is also ensured; meanwhile, extra components such as circular pipes, steel wire ropes and basket threaded are also saved in the connecting mechanism, so that the mounting and connecting processes of the components are simplified, and the material cost can also be reduced; and the fixedly connection mode of every two connecting pieces is firmer, and thus the position precision of the tower drum divided pieces is ensured.
Description
technical field [0001] The present application relates to the technical field of wind turbine towers, and in particular to a connection structure of tower sections and a method for making tower sections. Background technique [0002] The tower is an important supporting structure in the construction field, for example, the tower can be used as a support for a wind turbine. The size of the tower is generally large and it is difficult to transport as a whole. In order to solve the transportation problem, the tower is generally divided into multiple tower sections along the axial direction, and each tower section is divided into multiple tower sections along the radial direction , After pouring out the tower tube pieces, transport the tower tube pieces to the site, and then splicing them into a complete tower tube. [0003] According to a prior art known to the inventor, such as in the accompanying drawings figure 1 As shown, when multiple tower sections need to be rejoined i...
