Self-resetting energy dissipation haunch support with friction damper

The self-resetting energy dissipation haunch support comprises a first connecting base and a second connecting base which are connected to a frame beam and a frame column respectively, the first connecting base and the second connecting base are connected through the friction damper, and a bidirectional resetting mechanism is further arranged on the outer side of the friction damper in parallel. The haunch support device is additionally arranged at the key joint position of the steel frame, the friction damper and the two-way reset mechanism are installed in the middle of the haunch support, the two-way reset mechanism is formed by combining belleville spring anti-compression reset and tension reset rib anti-tension reset, damage to a main body structure is reduced, and in addition, the assembly technology is combined, so that the construction cost is reduced. The damage repair progress is accelerated. 本发明公开了一种带摩擦阻尼器的自复位耗能腋撑，包括分别连接至框架梁和框架柱的第一连接座和第二连接座，第一连接座和第二连接座通过摩擦阻尼器连接，摩擦阻尼器外侧还平行设有双向复位机构。本发明在钢框架关键节点位置增设腋撑装
