Fabricated self-resetting rotation constraint type concrete beam-column joint connecting structure and assembling method
The invention provides a fabricated self-resetting rotation constraint type concrete beam-column joint connecting structure and an assembling method. Transverse anchoring steel plate keys of the connecting structure are installed on the upper side and the lower side of the end of a prefabricated concrete beam, longitudinal anchoring steel plate keys are installed on the upper portion and the lower portion of a pre-embedded steel plate in a column, the longitudinal anchoring steel plate keys and the transverse anchoring steel plate keys are connected through rotating shaft bolts at the junction of beam-column joints, fan-shaped constraint steel plates and constraint rotating shafts between the longitudinal anchoring steel plate keys and the transverse anchoring steel plate keys are connected through constraint bolts, pre-tightening force applied to the rotating shaft bolts and the constraint bolts can effectively guarantee the flexural rigidity of the joints, and the joints are kept in an elastic state when the earthquake action is small. The problems that a dry type connection joint is poor in energy consumption and difficult to replace and repair after being damaged are effectively solved, connection between the prefabricated concrete beam and the prefabricated concrete column is achieved, and the requirements in actual design and construction are met.
本发明提出一种装配式自复位转动约束型混凝土梁柱节点连接结构及拼装方法，该连接结构的横向锚固钢板键安装在预制混凝土梁的端头上下侧，所述纵向锚固钢板键安装在柱内预埋钢板的上下部，纵向锚固钢板键与横向锚固钢板键在梁柱节点交界处通过转轴螺栓相连，二者间的扇形约束钢板和约束转轴间通过约束螺栓相连，对转轴螺栓和约束螺栓施加的预紧力能够有效保证节点的抗弯刚度，使节点在地震作用较小时保持弹性状态。解决了如何有效解决干式连接节点耗能不佳，且受损后更换和修复困难的问题，本发明实现预制混凝土梁和预制混凝土柱间的连接，以满足实际设计与施工中的需要。
