Graded energy dissipation assembly type beam hinge joint
The invention discloses a graded energy dissipation assembly type beam hinge joint which comprises at least one pair of first embedded parts and at least one pair of second embedded parts, and the first embedded parts and the second embedded parts are distributed in the connecting direction of two precast beams. Each pair of first embedded parts and each pair of second embedded parts are arranged at intervals, and the ends of the two sides are used for being connected with precast beams correspondingly; the first embedded parts and the second embedded parts which are adjacent on the same side are connected through energy dissipation parts, the second embedded parts are provided with limiting holes and reserved stranded wire holes, and each pair of second embedded parts are connected through limiting bolt pins penetrating into the limiting holes and prestressed stranded wires penetrating into the reserved stranded wire holes. After being combined, the grading energy dissipation structures are matched with one another, and in the normal use state, the prestress stranded wires bear the main stress effect; when an accidental load such as an earthquake or an external load is increased, a relative rotation angle is generated between the second embedded part and the precast beam, so that the energy dissipation part is driven to move, and at the moment, the energy dissipation part generates shear deformation to dissipate earthquake energy.
本发明公开了一种分级耗能装配式梁铰节点，包括至少一对第一预埋件和至少一对第二预埋件，且分别沿两个预制梁连接方向分布；每对第一预埋件与每对第二预埋件间隔布置，且两侧端部分别用于连接预制梁；同侧相邻的第一预埋件与第二预埋件之间通过耗能件相连接，第二预埋件设置有限位孔和绞线预留孔，每对第二预埋件之间通过穿入限位孔内的限位销栓及穿入绞线预留孔内的预应力绞线相连接；上述分级耗能结构组合后，相互配合，在正常使用状态下，预应力绞线承担主要受力作用；在遭遇例如地震等偶然荷载或外部荷载增大时，第二预埋件将会与预制梁之间产生相对转角，从而带动耗能件运动，此时，耗能件产生剪切变形耗散地震能量。
