Double steel plate-concrete composite wall cylinder structure and manufacturing method
The invention discloses a double-steel-plate-concrete composite wall cylinder structure and a manufacturing method. The double-steel-plate-concrete composite wall cylinder structure comprises a cylinder body, and the cylinder body is formed by welding a plurality of arc-shaped double-steel-plate-concrete composite wall subunits in the circumferential direction; the cylinder body is assembled in a segmented mode in the height direction, and adjacent segments in the vertical direction are fastened through connecting flanges. The high-strength bolts are adopted for reinforcing cooperative work of the steel plates and the interlayer concrete, local buckling of the steel plates is prevented, the self-compacting concrete has good flowability, the pouring quality is improved, the anti-cracking performance of the combined cylinder is improved by applying prestress, and the structural rigidity is improved. The advantages of a combined structure are fully exerted, the advantages of being high in overall strength, good in stability performance, good in economical efficiency and the like are achieved, all components are prefabricated in a factory and assembled on site, the construction efficiency can be remarkably improved, and wide engineering application prospects are achieved.
本发明公开了一种双钢板‑混凝土组合墙圆筒结构及制造方法，包括筒身，所述筒身沿环向由多个弧形双钢板‑混凝土组合墙子单元焊接而成；筒身沿高度方向分段组装，竖向相邻各段通过连接法兰紧固。本发明采用高强度螺栓加强钢板与夹层混凝土的协同工作，防止钢板局部屈曲，自密实混凝土具有良好的流动性，提高浇筑质量，施加预应力提高组合筒的抗裂性能，增加结构刚度。本发明充分发挥组合结构的优势，具有整体强度高，稳定性能好，经济性好等优势，所有构件均在工厂预制，现场装配，能显著提高施工效率，具有广阔的工程应用前景。
