Connecting joint of prefabricated hollow column and frame beam and construction method of connecting joint
The connecting joint comprises an upper connecting steel cylinder, a lower connecting steel cylinder, the prefabricated hollow columns and the frame beam, the upper connecting steel cylinder and the lower connecting steel cylinder are fixed to the tail ends of the prefabricated hollow columns on the upper side and the lower side of a beam column core area respectively, and a steel hoop is arranged at the bottom of the lower connecting steel cylinder; the bottom end of the steel hoop is correspondingly arranged at the top end of the beam column core area. Openings of the upper connecting steel cylinder and the lower connecting steel cylinder are opposite and are welded and sealed at a seam. Grouting holes are formed in the sealing plates of the upper connecting steel cylinder and the lower connecting steel cylinder, and concrete is fully poured into a cavity in the prefabricated hollow column, an abdominal cavity between the upper connecting steel cylinder and the lower connecting steel cylinder and the inner space of the steel hoop and the beam column core area. The column longitudinal bars can be connected in a staggered mode in the beam column core area, one-by-one connection of the column longitudinal bars in the beam column core area with the narrow construction space is avoided, through arrangement of the column longitudinal bars in the beam column core area can be guaranteed, construction is convenient and efficient, and the connection quality is reliable.
本发明公开了一种预制空心柱与框架梁的连接节点及其施工方法，连接节点包括上连接钢筒、下连接钢筒、预制空心柱和框架梁，上连接钢筒和下连接钢筒分别固定于梁柱核心区上下两侧预制空心柱末端，下连接钢筒底部设有一钢环箍，钢环箍的底端对应设置于梁柱核心区顶端，上连接钢筒和下连接钢筒开口相对并于接缝处焊接封闭；上连接钢筒和下连接钢筒的封板上均开设有灌浆孔，预制空心柱内部空腔、上连接钢筒和下连接钢筒之间的腹腔、以及钢环箍和梁柱核心区内部空间满灌混凝土。本发明既能够使柱纵筋的连接错开梁柱核心区，避免在施工空间狭小的梁柱核心区内进行柱纵筋的逐根连接，又可以保证梁柱核心区柱纵筋的贯通设置，施工方便高效，连接质量可靠。
