Friction pendulum multistage seismic isolation support seat based on shear thickening fluid
The invention relates to a friction pendulum multistage seismic isolation support seat based on shear thickening fluid. The friction pendulum multistage seismic isolation support seat comprises an upper support seat plate and a lower support seat plate, wherein the upper support seat plate is fixedly connected with an upper structure, and the lower support seat plate is fixedly connected with a foundation; a hinged sliding block is welded to the lower part of the upper support seat plate and is in sliding fit connection with the sliding surface of the lower support seat plate; a lateral displacement energy consumption device is welded on the lower support seat plate; the lateral displacement energy consumption device is mainly composed of a cylinder body, a piston, a piston rod, the shear thickening fluid, a ring-shaped baffle and an upper cover; the lower support seat plate is fixedly connected with the cylinder body in a welding sealing mode, the annular piston is arranged in the cylinder body, and the space between the cylinder body and the piston is filled with the shear thickening fluid; the ring-shaped baffle sleeves the periphery of the hinged sliding block, and a moving space is reserved between the ring-shaped baffle and the cylinder body; one end of the piston rod penetrates through the cylinder body and is welded with the piston, and the other end of the piston rod is fixedly riveted with the ring-shaped baffle; a sealing ring is arranged between the piston rod and the cylinder body; and the upper cover is welded to the top of the cylinder body so as to form a sealing cavity. The friction pendulum multistage seismic isolation support seat can rotate freely in all directions and has the advantages of high vertical bearing capacity and good durability.
本发明一种基于剪切增稠液的摩擦摆多级隔震支座，包括与上部结构固接的上支座板，与基础固接的下支座板；所述上支座下部焊接有铰接滑块，铰接滑块与下支座的滑移面滑动配合连接；下支座上焊接有侧移耗能装置；所述侧移耗能装置主要由缸体、活塞、活塞杆、剪切增稠流体、圈型挡板及上盖构成；下支座与缸体采用焊接密封固定连接，缸体内设有环形活塞，在缸体与活塞之间填充有剪切增稠流体；圈型挡板套设在铰接滑块外围，圈型挡板与缸体之间留有活动空间；活塞杆一端贯穿缸体与活塞焊接，活塞杆另一端与圈型挡板铆接固定；活塞杆与缸体之间设有密封圈；在缸体顶部焊接有上盖形成密封腔。本发明可以在各个方向上自由转动、竖向承载力大，耐久性好。
