Sleeve type full-bolt assembly RC frame node structure and assembly method
The invention discloses a sleeve type full-bolt assembly RC frame joint structure and an assembly method, and particularly relates to the technical field of civil water conservancy, the sleeve type full-bolt assembly RC frame joint structure comprises a prefabricated column and a prefabricated beam, and a sleeve type connecting structure is arranged between the prefabricated column and the prefabricated beam; the column end steel sleeve of the sleeve type connecting structure is welded to the prefabricated column steel reinforcement framework, and the beam end steel sleeve of the sleeve type connecting structure is welded to the prefabricated beam steel reinforcement framework, so that a joint plastic area is moved outwards to the prefabricated beam end. The sleeve type connecting structure comprises a column end steel sleeve with a reinforcing lug plate and a beam end steel sleeve with a reinforcing lug plate, and the reinforcing lug plate is arranged on one side of the column end steel sleeve. The fabricated joint is good in mechanical property, compared with a cast-in-place joint, the yield load is increased by 89%, the peak load is increased by 43%, and the initial rigidity is improved by about 70%. The connecting area steel structure can improve the overall deformation capacity of the joint, the ductility coefficient is improved by 50%, the equivalent viscous damping coefficient is improved by about 2 times, and good anti-seismic performance is shown.
本发明公开了套筒式全螺栓装配RC框架节点结构以及装配方法，具体涉及土木水利技术领域，该套筒式全螺栓装配RC框架节点结构包括预制柱和预制梁，所述预制柱与预制梁之间设置有套筒式连接结构，所述套筒式连接结构的柱端钢制套筒与预制柱钢筋骨架焊接，所述套筒式连接结构的梁端钢制套筒与预制梁钢筋骨架焊接，使节点塑性区外移到预制梁端。所述套筒式连接结构包括带加强耳板的柱端钢制套筒和梁端钢制套筒，所述加强耳板设置于柱端钢制套筒的一侧。本发明设计的装配式节点力学性能良好，相较于现浇节点屈服荷载提升89％，峰值荷载增大43％，初始刚度提高70％左右。连接区钢结构可提升节点整体变形能力，延性系数提高了50％，等效粘滞阻尼系数提高2倍左右，表现出较好的抗震性能。
