Fastener type tensile limiting and damping bearing
The invention discloses a fastener type tensile limiting and damping bearing. The fastener type tensile limiting and damping bearing comprises a damping rubber pad, an upper steel plate and a lower steel plate, the upper steel plate is anchored to an upper structure, and the lower steel plate is anchored to a lower structure. The fastener type tensile limiting and damping bearing is characterized in that tensile limiting mechanisms are symmetrically arranged on the bottom of the upper steel plate and each composed of a locking groove, a pull rod with a fastener at one end and a sleeve, the pull rods are sleeved with the sleeves with supports and connected to the sleeves in a sliding mode, the fasteners are inserted into the locking grooves in a sliding connection mode, the supports are anchored to the lower structure, and the hook-shaped locking grooves are fixedly connected to the upper steel plate. Compared with the prior art, the fastener type tensile limiting and damping bearing has the advantages that the structure is simple, the horizontal shear resistance and the vertical tensile deformation resistance are high, the stability is greatly improved, and the problems that high-rise buildings may topple in the earthquake damping process and the damping bearing is overstressed are well solved. Thus, laminated rubber damping bearings for high-rise buildings in severe earthquake regions can be widely applied and popularized.
