Self-resetting metal damper with built-in disc spring
The invention discloses a self-resetting metal damper with a built-in disc spring. The self-resetting metal damper comprises an external steel pipe, an internal steel pipe, a disc spring device, laminated rubber, a stiffening steel plate and an anchoring part. The lower end of the external steel pipe is connected with the damper lower connecting steel plate; upper and lower ends of the internal steel pipe are respectively connected with the damper bottom steel plate and the upper connecting steel plate; disc spring devices are arranged between the top steel plate and the first stiffening steel plate and between the second stiffening steel plate and the bottom steel plate in a sleeving manner; laminated rubber is arranged between the two stiffening steel plates; the anchoring part is formed by connecting an embedded steel plate and a damper connecting steel plate through high-strength bolts, and all the parts are independently machined and formed. Through reasonable connection design of all structural elements, the internal steel pipe and the external steel pipe of the damper bear external loads together, the disc spring device is always in a pressed state to provide restoring force, all the parts provide additional energy consumption in the elastoplastic deformation process, residual deformation and damage of structural components after an earthquake can be effectively reduced, and the service life of the damper is prolonged. Therefore, the recoverability of the function after the earthquake is improved.
本发明公开了一种内置碟簧可自复位金属阻尼器，包括外部钢管、内部钢管、碟簧装置、叠层橡胶、加劲钢板和锚固部件。外部钢管下端与阻尼器下连接钢板相连；内部钢管上下两端分别与阻尼器底部钢板和上连接钢板相连；顶部钢板与第一块加劲钢板之间，以及第二块加劲钢板与底部钢板之间套设有碟簧装置；两块加劲钢板之间设有叠层橡胶；锚固部件为预埋钢板与阻尼器连接钢板通过高强度螺栓连接，各部件独立加工成型。通过各构造元件的合理连接设计，使得阻尼器内部钢管与外部钢管共同承担外荷载，碟簧装置始终处于受压状态提供恢复力，各部件在弹塑性变形过程中提供附加耗能，能有效减小结构构件的震后残余变形和损伤，从而提高其震后功能的可恢复性。
