Sliding type multi-dimensional seismic isolation device for civil engineering

Abstract

The invention discloses a sliding type multi-dimensional seismic isolation device for civil engineering. The sliding type multi-dimensional seismic isolation device comprises a seismic isolation bearing lower plate, low friction coefficient material coating layers, an energy-dissipating steel sheet, a setup spring, a round steel sliding block, a circular ring sliding plate, a seismic isolation bearing upper plate, an upper plate round steel connecting block, anchor bars, a pre-tensioning spring and welding seams. The energy-dissipating steel sheet is arranged between the seismic isolation bearing upper plate and the seismic isolation bearing lower plate. One end of the energy-dissipating steel sheet is connected to the outer side surface of the round steel sliding block, and the other endof the energy-dissipating steel sheet is connected to the inner side surface of the seismic isolation bearing lower plate. The round steel sliding block is connected with the seismic isolation bearingupper plate in a threaded mode through the upper plate round steel connecting block, and the pre-tensioning spring is hinged to the seismic isolation bearing upper plate and the seismic isolation bearing lower plate. Buffer devices are separately arranged in the seismic isolation bearing lower plate and the seismic isolation bearing upper plate, and the buffer devices each comprise buffer holes,support plates and a cushion. The sliding type multi-dimensional seismic isolation device has the advantages of simple structure, convenient material selection, low cost, good durability, good seismicisolation and energy dissipation effects and easy construction, and can be widely applied to buildings and structures.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a sliding multi-dimensional vibration isolation device for civil engineering. Background technique [0002] At present, there are two types of seismic isolation devices for building anti-seismic, one is the seismic isolation device represented by lateral flexible deformation, such as rubber seismic isolation device, lead rubber vibration isolation pad, which has better energy dissipation capacity and certain Limiting capacity, but there are problems such as insufficient durability, limited deformation capacity, and relatively high cost. The other type is a shock-isolating device in the form of sliding, such as a shock-isolating device using balls, rollers, and gravel as sliding materials. Compared with the former, this type of device usually has high bearing capacity, low cost, and durability. Good and easy to make, but there are some problems: either there is no horiz...

[0002] At present, there are two types of seismic isolation devices for building anti-seismic, one is the seismic isolation device represented by lateral flexible deformation, such as rubber seismic isolation device, lead rubber vibration isolation pad, which has better energy dissipation capacity and certain Limiting capacity, but there are problems such as insufficient durability, limited deformation capacity, and relatively high cost

The other type is a shock-isolating device in the form of sliding, such as a shock-isolating device using balls, rollers, and gravel as sliding materials. Compared with the former, this type of device usually has high bearing capacity, low cost, and durability. Good and easy to make, but there are some problems: either there is no horizontal energy consumption limit and automatic reset function; or it does not have horizontal isotropy, and the performance in non-design directions is not ideal; The lifting of the building under the vertical seismic load is not effectively controlled, and it does not have the vertical seismic isolation capability
