Problems solved by technology

However, when the height-width ratio of the structure is large, the vertical seismic action is large, or the horizontal shear deformation of the laminated rubber bearing is large, tensile stress will be generated in the whole or part of the bearing section, while the ordinary rubber isolation bearing The tensile bearing capacity is very poor, and damage may occur under a small tensile stress, which may lead to the destruction of the entire isolation layer

Abstract

The invention belongs to the field of buildings and relates to a laminated rubber support seat. The laminated rubber support seat comprises an upper connecting member (1) and a lower connecting plate (2), wherein the upper connecting member (1) is positioned above the lower connecting plate (2); a stressed rubber gasket layer (4) is arranged in the upper connecting member (1); a shear press rubber gasket layer (5) is arranged between the upper connecting member (1) and the lower connecting plate (2); and the stressed rubber gasket layer (4) is fixedly connected with the shear press rubber gasket layer (5) through pulling and tying a steel stranded wire (7). When earthquake occurs, the shear press rubber gasket layer can generate vertical and horizontal deformation to bear an upper structure load and a vertical earthquake pressure; and the stressed rubber gasket layer bears the vertical earthquake tensile force generated at the support seat, so that the seismic isolation effect of a seismic isolation support seat can be achieved and the rubber support seat is prevented from being damaged when the support seat generates the tensile force.

Description

technical field [0001] The invention belongs to the technical field of vibration isolation and shock absorption of building structures, and relates to a laminated rubber bearing. technical background [0002] The so-called base isolation structure is to install a seismic isolation device between the structure and the foundation to prolong the natural vibration period of the structure, increase the structural damping, and prevent the transmission of seismic energy to the upper structure in order to reduce the seismic impact of the structure. resulting in a structural system. The lead core laminated rubber bearing is a widely used seismic isolation device. It is installed between the structure and the foundation during use, so that it can not only bear the vertical load of the upper structure, but also block the upward vibration of seismic energy due to its lateral flexibility. Transmission, but also can consume and absorb seismic energy to protect the safety of the superstru...
