A kind of energy-reducing shock-isolation bearing with limit position

Abstract

The invention discloses an improved limiting and energy-consuming seismic reduction and isolation support. The support comprises an upper flange plate and a lower flange plate, wherein fixing devices are arranged on the periphery of each of the upper flange plate and the lower flange plate, and the upper flange plate and the lower flange plate are fixed with a rubber support; each fixing device comprises a pair of right-angle bent plates, and the horizontal ends of the right-angle bent plates are fixed on the upper flange plate or the lower flange plate; the vertical ends of the right-angle bent plates correspond to each other, and a stress concentration preventing steel plate is arranged between every two vertical ends; each high-strength steel ring is fixed between the vertical ends of each group of upper and lower fixing devices. The support has the advantages as follows: 1) larger deformation can be limited; 2) the cost is saved: all that is required is to replace the high-strength steel rings under the condition that the steel rings are damaged and the support is not damaged, and due to the fact that the high-strength steel rings are relatively cheap, the cost can be saved; 3) the designability is high.

Description

technical field [0001] The invention relates to the field of anti-seismic technology of civil engineering structures, in particular to a shock-absorbing and isolating support with a buffer limit device Background technique [0002] The current shock-isolation bearing is one of the key technologies in civil engineering anti-seismic, and has been highly valued and concerned by the academic and engineering circles at home and abroad. In order to make the structure have a strong ability to resist external force damage such as earthquakes, it is often necessary to extend the period of the shock-absorbing support to reduce the upper horizontal inertial force, and to reduce the displacement response of the earthquake through its energy consumption while keeping the structure in an elastic state. The shock-absorbing and isolating bearings are usually equipped with energy-dissipating components. Common energy-dissipating components include viscous dampers, magneto-rheological dampers...

Problems solved by technology

[0003] At present, the shock-absorbing and isolating bearings used in engineering often have disadvantages such as oversized, complex structures, local maintenance is not easy after the earthquake, the entire bearing needs to be replaced, and tedious and lengthy reset work is required.
