Abstract

The invention discloses a tower drum and a reinforcement cage thereof. The reinforcement cage comprises first transverse reinforcing steel bars, first longitudinal reinforcing steel bars, second longitudinal reinforcing steel bars and second transverse reinforcing steel bars; the first transverse reinforcing steel bars extend in the transverse direction and are in an arc shape; the multiple first longitudinal reinforcing steel bars extend in the longitudinal direction and are arranged at intervals in the length direction of the first transverse reinforcing steel bars; the multiple second longitudinal reinforcing steel bars extend in the longitudinal direction, are in one-to-one correspondence to the multiple first longitudinal reinforcing steel bars and are located on the radial outer sides of the first longitudinal reinforcing steel bars; the multiple second transverse reinforcing steel bars are arranged at intervals in the longitudinal direction, and are in an arc shape; HRB500 level reinforcing steel bars are adopted in the reinforcement cage, the stress range of the reinforcing steel bars is within 150 MPa to 300 MPa, the stress amplitude is 150 MPa, and the cycle number is two million times. The reinforcement cage is stable in structure, large in strength and capable of improving the structural strength and anti-deformation capacity of the tower drum; in addition, the anti-fatigue strength can be improved, and the structural quality is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a reinforcement cage for a tower and a tower with the reinforcement cage. Background technique [0002] As the power generation efficiency of wind turbines increases, the length of the blades becomes longer and longer, and the height and cross-sectional size of the matching wind turbine towers are also increasing. Due to high cost and difficult transportation, steel structure towers are difficult to meet the construction requirements of large cross-section and high towers. Prefabricated concrete towers are gaining attention because they enable the economical construction of large wind turbines. [0003] In the related art, due to the structural limitation of the concrete tower, the structural strength of the concrete tower is small, and the deformation resistance is weak, so it needs to be improved. Contents of the invention [0004] The present invention aims t...
