Large-span space structure temperature deformation self-adaptive combined seismic isolation device
The invention relates to a large-span space structure temperature deformation self-adaptive combined seismic isolation device, which is mounted between an upper heavy roof and a lower structure, and comprises a rubber seismic isolation support, and a top plate and a bottom plate are respectively arranged above and below the support; the four novel self-adaptive passive viscous dampers are arranged along the periphery of the shock insulation support in a central symmetry mode, one ends of the dampers are connected with a top plate of the shock insulation support, and the other ends of the dampers are connected with a roof; the two-way sliding support is arranged above the shock insulation support and used for connecting the upper roof and the rubber shock insulation support, and free displacement of the roof in the horizontal direction under the working conditions of temperature rising and decreasing is achieved. Compared with the prior art, by innovating the self-adaptive piston structure of the passive viscous damper, the characteristics of zero rigidity and zero resistance of the device in a temperature rising and falling scene can be achieved, meanwhile, the characteristics of limited rigidity and limited resistance of the device in an earthquake action scene are guaranteed, and economical efficiency is achieved.
本发明涉及一种大跨度空间结构温度变形自适应组合隔震装置，安装在上部重型屋盖与下部结构之间，包括：橡胶隔震支座，支座上、下方分别设置顶板和底板；四个新型自适应被动式黏滞阻尼器，沿隔震支座四周呈中心对称布置，阻尼器一端与隔震支座顶板相连，另一端与屋盖连接；双向滑动支座，设置于隔震支座上方，用于连接上部屋盖与橡胶隔震支座，实现升降温工况下屋盖沿水平方向的自由位移。与现有技术相比，本发明通过创新被动式黏滞阻尼器的自适应活塞构造，可实现装置在升降温场景下的“零刚度、零抗力”特征，同时保障其在地震作用场景下的“有限刚度、有限抗力”特征，且具有经济性。
