Buckling restrained brace with locking device
The invention discloses a buckling restrained brace with a locking device, and relates to the technical field of buckling restrained braces.The buckling restrained brace is characterized in that a restraining component of the buckling restrained brace is arranged on the outer side of an energy consumption core in a sleeving mode, end plates comprise the bottom end plate and the top end plate, and the restraining component and the energy consumption core are welded to the bottom end plate; the energy consumption core and the end sleeve are welded to the top end plate. The locking device is fixed on the inner side of the end sleeve; the two limiting pieces are fixed to the outer side of the restraining component, and the locking device is located between the two limiting pieces. When the locking device moves along with the end sleeve and makes contact with any limiting piece on the two sides, the locking device returns to the initial zero position under the reciprocating earthquake effect, the locking device plays a locking role, and the relative movement of the end sleeve and the restraining component is limited. A reciprocating action mechanism of an earthquake load is combined with a locking device to realize self-resetting. After the locking device is triggered, the supporting rigidity and the bearing capacity are remarkably improved.
本发明公开了一种带有锁定装置的屈曲约束支撑，涉及屈曲约束支撑技术领域，屈曲约束支撑的约束构件套设于耗能核心的外侧，端板包括底部端板和顶部端板，约束构件与耗能核心焊接于底部端板上；耗能核心与端部套管均焊接于顶部端板上；锁定装置固定于端部套管的内侧；两个限位件均固定于约束构件的外侧，锁定装置位于两个限位件之间；当锁定装置跟随端部套管运动与两侧任一限位件接触后，且在往复地震作用下回复至初始零位，锁定装置发挥锁定作用，限制端部套管与约束构件的相对运动。利用地震荷载的往复作用机制，联合锁定装置实现自复位。锁定装置触发后，支撑的刚度和承载能力显著提升。
