Outer wrapped concrete-double corrugated steel plate concrete combined tower drum and construction method
The invention discloses an externally-wrapped concrete-double corrugated steel plate concrete combined tower drum and a construction method, the externally-wrapped concrete-double corrugated steel plate concrete combined tower drum comprises drum sections, the drum sections are formed by connecting a plurality of externally-wrapped concrete-double corrugated steel plate concrete combined tower drum units through prestressed bent bolts in the circumferential direction, and the adjacent drum sections are connected and fastened through L-shaped flange plates and high-strength bolts. Each combined tower drum unit comprises a corrugated inner steel plate, a corrugated outer steel plate, prestressed steel bars, encased concrete, interlayer concrete, an upper end plate and a lower end plate. The tower drum can be flexibly designed from bottom to top according to requirements, the upper tower drum section can be not filled with interlayer concrete, the dead weight of the tower drum structure can be reduced, and hoisting is convenient. The bearing capacity is improved, meanwhile, the section size of the component is reduced, good ductility and energy dissipation capacity are achieved, meanwhile, the bending resistance and crack resistance of the tower drum are improved, and the rigidity and stability of the tower drum are guaranteed. The combined tower drum is prefabricated in a fragmented mode, transported in a fragmented mode and assembled on site, and construction is efficient. The height of a fan tower can be greatly increased, and the development requirement of a low-wind-speed area is met.
一种外包混凝土‑双波纹钢板混凝土组合塔筒及施工方法，包括筒段，筒段沿环向由多个外包混凝土‑双波纹钢板混凝土组合塔筒单元通过预应力弯螺栓进行连接，相邻的筒段通过L形法兰盘及高强度螺栓连接紧固。组合塔筒单元包括波纹内钢板、波纹外钢板、预应力钢筋、外包混凝土、夹层混凝土、上端板、下端板。塔筒可根据需求自下而上灵活设计，上部塔筒段可以选择不填充夹层混凝土，可减轻塔筒结构自重，方便吊装。本发明承载能力提高同时减小构件截面尺寸，具有良好延性与耗能能力，同时提升了塔筒的抗弯和抗裂性能，保证了塔筒的刚度和稳定性。组合塔筒分片预制、分片运输、现场装配，施工高效。可大幅提高风机塔筒高度，适应低风速区发展要求。
