Abstract

The invention provides a tension resisting and twisting resisting combined shock isolation device with the self-restoring function, and belongs to the technical field of shock absorbing and isolating technique of structural engineering. The device mainly comprises a high-flexibility device (1), a rigid supporting pedestal (2), a transverse limiting sliding block (3), a transverse shock isolation linear guide rail (4), a transverse shock absorbing tension spring (5), a transverse shock absorbing tension spring support (6), a layering separating plate (7), a longitudinal limiting sliding block (8), a longitudinal shock isolation linear guide rail (9), a longitudinal shock absorbing tension spring support (10) and a longitudinal shock absorbing tension spring (11). The combined shock isolation device has the advantages that the material performance of each part can be fully utilized; in addition, the shortcoming of poor tension resisting capacity and vertical bearing capacity of a rubber support seat is overcome; the advantages of high tension resisting capacity and twisting resisting capacity, and outstanding effect on shock isolation for bases of the high-flexibility device and a high-flexibility structure are brought.

Description

technical field

[0001] The invention belongs to the technical field of shock absorption and isolation in structural engineering, and relates to a roller-type linear guide rail with a small friction coefficient, and two layers of vertical guide rails are arranged on the upper and lower layers, so as to meet the requirements of shock isolation in multiple directions. A shock-absorbing extension spring that can provide structural rigidity and self-reset the upper structure forms a perfect combined shock-isolation device. The invention is low in cost, has strong resistance to tension, torsion, and overturning, and has self-resetting function, outstanding shock isolation effect, and convenient construction. Prospects. Background technique
