Inter-column connection type self-resetting variable friction damper
The invention discloses an inter-column connection type self-resetting variable friction damper which comprises an upper T-shaped inner plate, a lower T-shaped inner plate, an outer plate, a disc spring, a nut, a web connecting bolt, an upper connecting bolt and a lower connecting bolt. The T-shaped inner plate and the outer plates on the two sides are connected and fixed through bolts, slope surfaces capable of being attached are machined on the T-shaped inner plate and the outer plates, and when the T-shaped inner plate and the outer plates relatively move in the horizontal direction, the outer plates on the two sides move outwards, and the disc spring is pressed and deformed. Pressure generated by deformation of the disc springs causes normal force between the slope surfaces, then friction force is generated, meanwhile, the pressure generated by deformation of the disc springs changes along with changes of deformation, and a variable friction mechanism is achieved. Longitudinal slopes are machined on the inner side of the outer plate and the two sides of the web plate of the T-shaped inner plate, structural interlayer displacement caused by an earthquake enables the T-shaped inner plate and the outer plate to horizontally and relatively move, the disc spring is pressed and deformed, meanwhile, the pressure generated by deformation of the disc spring changes along with changes of deformation, and a variable friction mechanism is achieved.
本发明公开了一种柱间连接型自复位变摩擦阻尼器，包括上T形内板、下T形内板、外板、碟簧、螺母、腹板连接螺栓、上连接螺栓和下连接螺栓。T形内板和两侧外板通过螺栓连接固定，T形内板和外板上均加工有可贴合的坡面，当T形内板与外板发生水平方向相对移动时，两侧外板向外移动，碟簧受压变形。碟簧变形产生的压力引起坡面之间的法向力，进而产生摩擦力，同时碟簧变形产生的压力大小随变形量的变化而变化，实现了变摩擦机制。本发明外板的内侧和T形内板的腹板两侧均加工有纵向坡面，地震引起的结构层间位移使T形内板和外板发生水平相对移动，碟簧受压变形，同时碟簧变形产生的压力大小随变形量的变化而变化，实现了变摩擦机制。
