Stacked arc-shaped damping device
The invention relates to a stacked arc-shaped damping device, which belongs to the technical field of earthquake resistance of engineering structures, and mainly comprises a hinged connecting piece, a triangular plate type truss, an arc-shaped damping unit, a sliding block assembly and a guide rail assembly, the hinge connecting pieces are welded to the triangular plate type trusses, pin shaft holes are formed in the hinge connecting pieces and the sliding block assemblies, the arc-shaped damping units serve as energy dissipation main bodies, and the multiple arc-shaped damping units are stacked and overlapped together to be combined into a damping unit set. The two ends of each damping unit set are connected with the hinge connecting piece and a hinge pin hole in the sliding block assembly through series-connection hinge pins respectively, and the two sides of the hinge connecting piece and the two sides of the sliding block assembly are symmetrically connected with the damping unit sets. The guide rail assembly is in sliding connection with the sliding block assembly. Compared with the prior art, overall energy consumption is achieved through bending deformation of the arc-shaped damping units, and the requirement of a bridge in a high-intensity area for large displacement in the transverse bridge direction of the seismic mitigation and isolation device can be met. And the device has the advantages of small installation space, convenience in later maintenance, light weight, low cost and the like.
本发明涉及堆叠式弧形减震装置，属于工程结构抗震技术领域，主要包括铰接连接件、三角板式桁架、弧形阻尼单元、滑块组件和导轨组件；铰接连接件焊接在三角板式桁架上，铰接连接件与滑块组件上设置有销轴孔，弧形阻尼单元作为耗能主体，若干片弧形阻尼单元堆叠重合在一起合并为阻尼单元组，阻尼单元组的两端分别通过串接销轴与铰接连接件以及滑块组件上的销轴孔连接，述铰接连接件与滑块组件的两侧均对称连接阻尼单元组；导轨组件与滑块组件实现滑动连接。与现有技术相比，本发明通过弧形阻尼单元弯曲变形实现整体耗能，可适应高烈度地区桥梁对减隔震装置提出的横桥向大位移的要求。且具有安装空间小，后期维护方便，重量轻成本低等优点。
