Embodiment 1

[0058] A sliding ball multi-stage shock-absorbing support,

[0059] It includes a shock absorbing ball 100, a lead pillar 200, a first connecting plate 300 and a second connecting plate 400;

[0060] The first connecting plate 300 and the second connecting plate 400 are spaced apart from top to bottom, and an installation space is formed between them;

[0061] The lead pillar 200 is arranged in the installation space, and the two ends are used to support the first connecting plate 300 and the second connecting plate 400;

[0062] The shock-absorbing ball 100 is disposed in the installation space, and is used for rolling and supporting the first connecting plate 300 when the support of the lead pillar 200 fails.

[0063] Such as figure 1 The schematic diagram of the overall structure of the sliding ball multi-stage shock-absorbing bearing provided by the embodiment of the present invention is shown as follows:

[0064] During use, when an earthquake occurs, the lead core pilla...

Abstract

The invention relates to the technical field of damping supports, in particular to a sliding ball multi-stage damping support. The problems that in the prior art, according to a lead core damping support, deformation recovery is hard when a lead core is thick and large, internal damping distribution is not uniform, and the damping effect cannot continue to be brought into play when an aftershock happens are solved. The sliding ball multi-stage damping support comprises damping balls, a lead core supporting column, and a first connecting plate and a second connecting plate which are arranged from bottom to top in a spaced mode, and an installing space is formed between the first connecting plate and the second connecting plate, the lead core supporting column supports the first connecting plate and the second connecting plate, and the damping balls are arranged inside the installing space for supporting the first connecting plate in a rolling mode when supporting of the lead core supporting column loses efficacy. When the support is in use, the lead core supporting column absorbs energy generated by an earthquake at first for primary damping and energy dissipation, when the lead core supporting column loses efficacy, the damping balls drive the first connecting plate and the second connecting plate to slide horizontally in a staggered mode, energy generated by aftershocks is absorbed, and secondary damping energy dissipation can be performed.

Description

technical field [0001] The invention relates to the technical field of shock-absorbing bearings, in particular to a sliding ball multi-stage shock-absorbing bearing. Background technique [0002] Because earthquakes are difficult to predict, when earthquake disasters occur, they often cause heavy economic losses and casualties, so the development of shock absorbing devices is particularly important. Therefore, shock-absorbing bearings are often used for shock-absorbing and shock-absorbing during construction. [0003] The most widely used in the prior art is the shock-absorbing support of a single lead core laminated rubber steel plate represented by a lead core, which absorbs earthquake energy by deformation of the lead core, and then relies on the shearing force of the rubber and the recrystallization process of the lead core Recover deformation, but it is difficult to recover deformation when the lead core is relatively thick, and a single lead core will also cause uneve...
