Replaceable self-resetting energy dissipation assembly type vertical connection joint
The invention relates to a replaceable self-resetting energy dissipation assembly type vertical connecting joint which comprises a precast concrete column, an embedded connecting plate, an energy dissipation connecting plate and SMA self-resetting bolts. The two prefabricated concrete columns are connected in the vertical direction, the ends of the two prefabricated concrete columns are attached, an embedded connecting plate is arranged on the side surface of the connecting position of the two prefabricated concrete columns, a notch is inwards formed in the embedded connecting plate, and a box-shaped connecting piece is arranged in the notch. The SMA self-resetting bolts penetrate through the two adjacent box type connecting pieces; the embedded connecting plate is covered with the energy consumption connecting plate, and two C-shaped energy consumption grooves are formed in the energy consumption connecting plate. The energy dissipation connecting plate and the reset bolt are combined, when a small earthquake occurs, the energy dissipation connecting plate dissipates energy through friction and deformation, but deformation of all parts in the connecting joint is within the elastic range of the self-reset bolt, and self-recovery can be achieved through the SMA self-reset bolt. And when a large earthquake occurs, the damage of the component only occurs on the energy-consuming connecting plate, so that the occurrence and development of cracks on the precast concrete column are avoided.
本发明涉及一种可更换的自复位耗能装配式竖向连接节点，包括：预制混凝土柱、预埋连接板、耗能连接板和SMA自复位螺栓；两根预制混凝土柱沿竖向连接，端部相贴合，在两根预制混凝土柱的连接位置的侧表面设置有预埋连接板，预埋连接板向内设置有槽口，槽口内设置有盒型连接件；SMA自复位螺栓穿过相邻的两个盒型连接件；耗能连接板覆盖于预埋连接板上，其上设置有两个C型耗能槽。本发明采用耗能连接板与复位螺栓相结合，发生小震时，耗能连接板通过摩擦和形变耗能，但连接节点内所有部位的形变均处于自复位螺栓的弹性范围内，可以通过SMA自复位螺栓实现自行恢复。发生大震时，构件的破坏仅发生在耗能连接板上，避免了预制混凝土柱上裂纹的出现和发展。
