Anti-torsion combined shock isolation device with self-resetting function

Abstract

The invention discloses an anti-torsion combined shock isolation device with a self-resetting function. The anti-torsion combined shock isolation device comprises a lower embedded plate and a lower support, a rubber column is fixedly connected to the upper surface of the lower support, a steel plate is fixedly connected to the interior of the rubber column, and an annular limiting chute is formedin the position, on the side of the rubber column, of the surface of the lower support; a sliding block is arranged in the annular limiting sliding groove, a damping mechanism is fixedly connected tothe upper surface of the sliding block, and an upper embedded plate is fixedly connected to the top of the upper support. Larger tension resistance and anti-torsion capacity is provided for the devicethrough the damping mechanism, the rubber column and the steel plate play a role in consuming pressure borne during vibration, a remarkable shock insulation effect can be achieved, meanwhile, when the steel plate is extruded, part of vertical pressure can be converted into horizontal pressure, the horizontal pressure is evenly distributed along the surface of the steel plate, and therefore the horizontal pressure is counteracted, the compressive strength of the rubber column is improved, and the shock insulation strength is enhanced.

Description

technical field [0001] The invention relates to the technical field of engineering shock absorption, in particular to a combined shock isolation device with self-resetting function and anti-torsion. Background technique [0002] Earthquakes, also known as ground motions and ground vibrations, are a natural phenomenon in which vibrations are generated during the rapid release of energy from the earth's crust, during which seismic waves are generated. Earthquakes bring too much disaster and pain to humans, but earthquakes themselves are not very important to humans. Earthquake disasters are mainly manifested in the secondary damage caused by the collapse of buildings in the disaster-stricken area, which has brought great losses to people's lives and property. Seismic isolation technology has become the most widely used technology because of its simple concept, obvious effect and stable performance. One of the extensive shock absorption methods, with the development of shock is...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a combined shock-isolating device with self-resetting function and anti-torsion, which has greater tensile and torsion resistance, reduces wear on the device during vibration, and offsets horizontal pressure , improve the compressive strength, enhance the strength of the shock isolation, etc., and solve the problem that the shock isolation effect is not ideal, and the tension of the shock isolation support causes the deformation of the shock isolation support to exceed the limit.
