Prefabricated bent cap and pier stud quick dry type connecting joint of multiple resistance system
The invention discloses a quick dry type connection node for a prefabricated cover beam and a pier stud of a multi-resistance system, which comprises the prefabricated cover beam and a prefabricated stand column, a vertical framework is pre-buried in a connection area of the prefabricated cover beam, and a groove is formed in the top of the connection area of the prefabricated cover beam; the groove is used for embedding an anchor head and paving and filling waterproof asphalt; a pier top steel plate is pre-buried in the top end face of the prefabricated pier column, and finish rolling deformed steel bars are vertically pre-buried in a top section connecting area of the prefabricated pier column according to the set buried depth. The lower end, embedded in the prefabricated pier column, of the finish rolling deformed steel bar is provided with a bolt pier head, and the protruding upper section of the finish rolling deformed steel bar penetrates through the vertical framework and is connected with an anchor head in an anchoring mode according to set pre-tightening force. The method is high in assembly rate, free of on-site wet connection workload and high in construction speed; a multi-resistance system of the connecting structure is achieved, the safety degree and redundancy of the structure are improved, waterproof asphalt is adopted for covering, airtight waterproof is conducted on the connecting structure, implementation is easy, and cost is low.
本发明公开一种多重抗力体系的预制盖梁与墩柱快速干式连接节点，包括预制盖梁和预制立柱，所述预制盖梁的连接区域中预埋竖向骨架，所述预制盖梁的连接区域顶部设凹槽；所述凹槽用于埋设锚头并铺填防水沥青；所述预制墩柱的顶部端面预埋墩顶钢板，所述预制墩柱的顶段连接区域中按设定埋深呈竖向预埋精轧螺纹钢；所述精轧螺纹钢埋入在预制墩柱中的下端设有螺栓墩头，精轧螺纹钢凸伸的上段贯穿竖向骨架与锚头按设定预紧力锚固连接。本发明的装配化率高，现场无湿接作业量，施工速度快；实现连接构造的多重抗力体系，提升结构的安全度与冗余度，采用防水沥青覆盖，对连接构造进行密闭防水，实施简单且成本低。
