Steel damping support with space universality

Abstract

The invention relates to a steel damping support with space universality. The support comprises a support module and an earthquake limiting module; the support module comprises a bottom plate, a top plate and a spherical crown assembly, the bottom plate and the spherical crown assembly are in movable contact and have a longitudinal degree of freedom, and the spherical crown assembly and the top plate are in movable contact and have a transverse degree of freedom; the earthquake limiting module comprises a first transmission rib plate, a second transmission rib plate, a first rod-shaped damping unit and a second rod-shaped damping unit, the first transmission rib plate and the second transmission rib plate are arranged in the longitudinal direction and the transverse direction respectively, and the two ends of the first transmission rib plate are connected with the spherical crown assembly and the middle of the first rod-shaped damping unit respectively. Compared with the prior art, the steel damping support can adapt to various installation space scenes in a bridge engineering supporting system, and large-tonnage damping force can be selectively provided according to vibration control requirements (the vibration control direction and whether a limiting function is provided in the vertical direction or not).

Description

technical field [0001] The invention belongs to the technical field of damping structures, and relates to a steel damping support with spatial universality. Background technique [0002] Bridge seismic isolation technology can effectively prevent the main structure of the bridge from being seriously damaged in the earthquake. Among them, the controllable seismic behavior is the basic technical requirement for a series of seismic isolation devices. For engineering applications, strong space adaptability and good engineering practicability are another basic requirement for shock-absorbing and isolating devices. [0003] Chinese patents CN202954294U and CN201485785U have successively disclosed a bidirectional damping energy-dissipating pot bearing and an elastic-plastic anti-drop beam spherical steel bearing. The former occupies a large plane space because the damping unit is ε-shaped, and the latter occupies a large plane space because the damping unit is The elastic-plastic...

Problems solved by technology

[0003] Chinese patents CN202954294U and CN201485785U have successively disclosed a bidirectional damping energy-dissipating pot bearing and an elastic-plastic anti-drop beam spherical steel bearing. The former occupies a large plane space because the damping unit is ε-shaped, and the latter occupies a large plane space because the damping unit is The elastic-plastic column occupies a large vertical space, and it is difficult to anchor the root of the damping unit. The higher the elastic-plastic column, the more prominent the aforementioned problems

In addition, for the situation where higher tonnage damping force and larger stroke displacement are required, the problem of space occupation becomes more prominent

Therefore, the above two devices are subject to different degrees of restrictions when applied in different engineering scenarios
