Slide rail type anti-overturning shock insulation bearing

Abstract

The invention discloses a slide rail type anti-overturning shock insulation bearing which comprises a slide block, slide rails, and slide cavities arranged at the left sides and the right sides of the slide rails respectively, wherein the slide block is clamped on the slide rails and slides transversely along the slide rails; end plates are mounted at the left and right end parts of the slide rails respectively; a spring is connected between each end plate and the slide block; the end plates are arranged in the slide cavities corresponding to the end plates; the end plates drive the slide rails to slide longitudinally on the slide cavities; closing plates are arranged at the front ends and the rear ends of the slide cavities; and a spring is connected between each end plate and each closing plate corresponding to the end plate. The bearing can vertically provide higher resistance to tension, allow connected upper and lower building structures to slide in any directions in a horizontal plane, bear higher horizontal displacement and provide horizontal resilience.

Description

technical field [0001] The invention relates to the technical fields of civil engineering and bridge engineering, in particular to a slide rail type anti-overturning shock-isolation bearing used for civil engineering structures and bridge structures. Background technique [0002] Earthquakes are the main disasters that threaten the safety of people's lives and properties. There are many destructive earthquakes every year around the world. The Wenchuan earthquake in 2008 and the Yushu earthquake in 2010 caused heavy losses to people's lives and properties. Practice has proved that in the design of building structures, setting up seismic isolation bearings is the most effective way to reduce earthquake disasters. [0003] According to the requirements of the national standard GB50011-2010 "Code for Seismic Design of Buildings", rubber seismic isolation bearings are usually used as seismic isolation devices, but rubber seismic isolation bearings can only withstand the pressure ...

AI Technical Summary

Problems solved by technology

[0003] According to the requirements of the national standard GB50011-2010 "Code for Seismic Design of Buildings", rubber isolation bearings are usually used as isolation devices, but rubber isolation bearings can only withstand the pressure transmitted from above, and the ability to withstand tension is limited

Under the action of strong earthquakes, the seismic isolation bearings of medium and high-rise buildings may bear large tensile forces, but the tensile capacity of rubber seismic isolation bearings is insufficient, and the application range is restricted

At the same time, the building may undergo a large horizontal displacement under strong earthquakes, while the horizontal displacement allowed by the rubber bearing is small, which cannot meet the requirements of high-intensity earthquake resistance for buildings and bridges in engineering practice.
