Seismic isolation limit support

Abstract

The invention discloses a shock-isolation limit bearing, which comprises a base, on which a baffle plate is arranged to enclose its boundary, and a slideway is also arranged on the base; In the slideway on the bottom plate, and the support main body slider is located in the area enclosed by the baffle plate; and an elastic limiting part, one end of which is connected with the support main body slider, and the other end It is connected with the baffle plate on the base; wherein, when an earthquake occurs, the vibration displacement of the shock-isolation body arranged on the slider of the main body of the support occurs, and the vibration displacement is transmitted to the elastic limit part, and the elastic limit part is opposite The movement of the slider on the main body of the bearing and its deformation to reduce the displacement response of the earthquake. The invention has the advantages of simple structure, low cost, clear division of functions of each component, guaranteed quality, convenient replacement and good shock isolation effect.

Description

technical field [0001] The invention relates to the technical field of anti-seismic structures in construction engineering. More specifically, the present invention relates to a shock-isolation limit support for buildings. Background technique [0002] At present, the types and characteristics of traditional seismic isolation bearings are as follows: The isolation measures adopted at home and abroad can be divided into two types of rubber bearing isolation and sliding bearing isolation. The former is generally a thin steel plate sandwiched between layers of rubber. Add lead core in the center. This structure can lengthen the natural vibration period of the house, keep it away from the characteristic period of the seismic wave, reduce the earthquake effect, and has the function of automatic reset. However, its shortcomings are also very obvious. Because the main functions of the support of this system, that is, vertical bearing, horizontal shear force and reset, are all rea...

Problems solved by technology

[0003] In the latter, the traditional sliding isolation technology is to set low-friction sliding elements and limiters on the foundation or between floors, etc., to effectively limit the transmission of seismic energy to the upper part and to the lower part through relative sliding motion and frictional energy consumption. Feedback, but the technology only relies on frictional energy consumption and has no other energy consumption methods. The earthquake time displacement is too large. If no flexible material is added between the main body of the support and the limiter, it will directly collide with the limiter, causing The limit part is damaged; if flexible materials are added, some problems in setting and design will affect the sliding of the main body of the support, which is not conducive to shock isolation
