The invention provides a prefabricated concrete beam dry-type connecting joint and a connecting method thereof, and belongs to the field of prefabricated buildings. An upper high-strength bolt is arranged above the top face of a prefabricated concrete beam (within the height of a floor), so that the connecting force arm of the upper high-strength bolt is increased; therefore, equal-strength joint connection with the reinforcing steel bars in the beam is achieved through the single large-diameter high-strength bolt, and installation convenience is greatly improved. The upper high-strength bolt and the lower high-strength bolt are combined for clamping, so that tensile and compression-resistant bidirectional force transmission is realized (in a normal state, the upper high-strength bolt is tensile, and the lower high-strength bolt is compression-resistant; ), so as to cope with the bending moment change of the precast concrete beam under the action of the reciprocating load.
本发明提供一种预制混凝土梁干式连接节点及其连接方法，属于装配式建筑领域，将上高强度螺栓设置在预制混凝土梁的顶面以上(楼板高度内)，以增加上高强度螺栓连接力臂，从而利用单颗大直径高强度螺栓实现了与梁内钢筋等强的节点连接，安装便利性极大提升；并设置支托座抗剪，结合上、下高强度螺栓夹紧实现了抗拉抗压双向传力(常态时上高强螺栓抗拉、下高强螺栓抗压；地震时可能会相反)，以应对预制混凝土梁在往复荷载作用下的弯矩变号。
