Abstract

The invention relates to the technical field of damping supports, and particularly relates to a bidirectional rolling shaft multi-stage damping support. The problems that in the prior art, a lead coredamping support has difficulty in recovering deformation when a lead core is thick, internal damping distribution is nonuniform, and the damping effect cannot continue to be played in aftershock aresolved. The bidirectional rolling shaft multi-stage damping support comprises a first damping rolling shaft, a second damping rolling shaft, a lead core supporting column, a first connecting plate, asecond connecting plate and a third connecting plate, the lead core supporting column, the first damping rolling shaft and the second damping rolling shaft are arranged in a mounting space formed by the first connecting plate, the second connecting plate and the third connecting plate separately, when the lead core supporting column support fails, the first damping rolling shaft and the second damping rolling shaft roll to support the first connecting plate and the second connecting plate, when the support is used, the lead core supporting column absorbs energy generated by an earthquake firstto perform first-stage damping energy consumption, and in the aftershock, the first damping rolling shaft and the second damping rolling shaft perform second-stage damping energy consumption.

Description

Technical field [0001] The invention relates to the technical field of shock-absorbing bearings, and in particular to a bidirectional roller multi-stage shock-absorbing bearing. Background technique [0002] Since earthquakes are difficult to predict, when earthquake disasters occur, they often cause heavy economic losses and casualties, so the development of shock absorption devices is particularly important. Therefore, shock-absorbing bearings are often used for shock absorption and shock absorption during construction. [0003] The most widely used in the prior art is a single lead-core laminated rubber steel damping bearing represented by a lead core, which relies on the deformation of the lead core to absorb seismic energy, and then relies on the shearing force of the rubber and the recrystallization process of the lead core Deformation is restored, but it is difficult to restore deformation when the lead core is relatively thick, and a single lead core will cause uneven damp...
