High-bearing-capacity tensile energy dissipation shock insulation device

Abstract

The invention discloses a high-bearing-capacity tensile energy dissipation shock insulation device, and belongs to the technical field of building engineering structure shock insulation. The shock insulation device comprises an upper connecting plate, a plurality of U-shaped supports, a spherical sliding block, a lower sliding groove, a lower connecting plate, and tensile and shear resistance connectors. The tensile and shear resistance connectors are arranged on one face of the upper connecting plate, and the spherical sliding block is arranged on the other face of the upper connecting plate.According to the movement energy dissipation radius of the spherical sliding block, the lower sliding groove is determined, the lower sliding groove is in rigid connection with the lower connecting plate, the multiple U-shaped supports are arranged, the U-shaped supports are then evenly distributed on the front, back, left and right parts of the spherical sliding block, wherein upper legs of theU-shaped supports are arranged on the upper connecting plate, lower legs of the U-shaped supports are arranged on the lower connecting plate, and the tensile and shear resistance connectors are arranged on the lower connecting plate. The high-bearing-capacity tensile energy dissipation shock insulation device has the characteristics of high bearing capacity, good horizontal shock isolation and tensile energy dissipation, being economical and practical, and environmental protection.

Description

technical field [0001] The invention belongs to the field of seismic isolation of building engineering structures, and more specifically relates to a high-bearing-capacity tensile energy-dissipating seismic isolation device. Background technique [0002] Seismic isolation technology mainly isolates the ground motion from the upper structure through the isolation device, so as to achieve the effect of reducing the seismic response of the structure. [0003] The existing types of isolation devices mainly include natural rubber isolation bearings (LNR), lead rubber isolation bearings (LRB), and high damping rubber isolation bearings (HDR). These isolation bearings are widely used in many civil structures, especially those sensitive to earthquake action, wind load, blast impact load, etc. However, with the development of contemporary civil structures towards large-span, super-high-rise, and large-scale complexes, traditional seismic isolation bearings may have insufficient bear...
