Description
技术领域technical field
本发明涉及一种阻尼机构，尤其涉及一种高耗能密封型双板式粘滞阻尼墙。The invention relates to a damping mechanism, in particular to a high-energy-consuming sealed double-plate viscous damping wall.
背景技术Background technique
建筑物在大地震作用下，主要依靠结构件吸收地震能量，建筑物之间的刚性连接使得在吸收能量过程中容易导致坍塌，抗震效果差，因而需要在建筑物中增加减震机构来增强减震效果，传统的减震方式为增加弹性结构件，但弹性件的弹性受时间影响较大，且弹性件仅在弹性方向上具有较好的回复力，虽现有技术中有将粘滞阻尼技术应用于减震效果，但减震效果不佳。Under the action of a large earthquake, buildings mainly rely on structural parts to absorb seismic energy. The rigid connection between buildings makes it easy to collapse during the energy absorption process, and the seismic effect is poor. The traditional shock absorption method is to add elastic structural parts, but the elasticity of the elastic parts is greatly affected by time, and the elastic parts only have a good restoring force in the elastic direction. The technology is applied to the shock absorption effect, but the shock absorption effect is not good.

进一步的，所述上连接板与下连接板均为钢板。Further, the upper connecting plate and the lower connecting plate are both steel plates.
进一步的，所述粘滞阻尼液的上端面小于所述外钢箱上端面。Further, the upper end surface of the viscous damping fluid is smaller than the upper end surface of the outer steel box.
进一步的，所述阻尼钢板与所述槽孔宽边之间的间隙大于楼层弹塑性位移的限值。防止在地震作用下，阻尼钢板纵向运动与密封板发生撞击。Further, the gap between the damping steel plate and the broad side of the slot hole is larger than the limit of the elastic-plastic displacement of the floor.

The inner slot moves in the length direction, and through the friction between the steel plate and the viscous damping material, it can effectively consume the seismic energy and reduce the response of the structure. The double damping steel plate further increases the seismic dissipation capacity of the viscous damping wall. In the invention, an end cover is arranged at the opening of the outer steel box to realize the sealing of the outer steel box, so as to prevent the viscous damping liquid from shaking during the earthquake process, causing the liquid to overflow and the damping force of the viscous damping wall to decrease. The distance between the edge of the damping steel plate and the slot hole of the end cover is greater than the limit of the elastic-plastic displacement of the floor under the rare earthquake, so as to ensure the stable seismic performance of the viscous damping wall.
