Thick meat rubber-lead core rubber combined support with vertical limiting function
The invention relates to a thick rubber-lead rubber combined support with a vertical limiting function, which comprises a thick rubber support, a lead rubber support, a sleeve and a vertical guide rod, the sleeve is embedded in a hole formed in the middle of the thick rubber support, the vertical guide rod is inserted in the sleeve, the sleeve comprises a wide part and a narrow part, and the vertical guide rod comprises a wide part and a narrow part. Under the normal load, the overall vertical rigidity of the combined support is the series rigidity of a pure thick rubber support and a lead core rubber support, and under the horizontal earthquake effect, horizontal force between an upper flange plate and a lower flange plate of the thick rubber support is mainly transmitted through contact between a vertical guide rod and a steel pipe sleeve; when the large earthquake effect causes large vertical compressive deformation and large tensile deformation of the thick rubber support, the vertical guide rod and the sleeve provide contact rigidity. Compared with the prior art, the device has the advantages of vibration isolation, simple support connecting structure, convenience in production and installation, capability of preventing the device from being damaged by tension and rigidly swinging and the like.
本发明涉及一种带竖向限位功能的厚肉橡胶‑铅芯橡胶组合支座，其包括厚肉橡胶支座、铅芯橡胶支座、套筒、竖向导杆，套筒内嵌于厚肉橡胶支座中间开的孔洞中，竖向导杆插于套筒内，套筒包括宽部和窄部，竖向导杆包括宽部和窄部。正常荷载下，组合支座整体竖向刚度为纯厚肉橡胶支座与铅芯橡胶支座的串联刚度，水平地震作用下，厚肉橡胶支座上下法兰板之间的水平力主要由竖向导杆与钢管套筒之间接触传递，当地震作用较大导致厚肉橡胶支座竖向受压变形较大和受拉变形较大时，竖向导杆和套筒提供接触刚度。与现有技术相比，本发明具有隔振/震、支座连接构造简单便于生产安装、防止装置受拉破坏和刚性摇摆等优点。
