Description

Technical Field

[0001] The utility model belongs to the technical field of shock absorption of building facilities, and particularly relates to a cone-shaped buckled shock-absorbing support. Background Art

[0002] The cone-shaped buckle-connected shock-absorbing bearing refers to a shock-absorbing device with a buckle-connected structure and a cone shape, which is installed between the building and the foundation. The early shock-absorbing devices were mainly laminated rubber shock-absorbing bearings composed of rubber and thin steel plates alternately stacked. Later, lead rods were added to them to form lead-core laminated rubber shock-absorbing bearings. Its working principle is that after the shock-absorbing device is installed, the natural vibration period of the structure is greatly extended, so that the natural vibration period of the upper structure is far away from the superior period of the input ground vibration, thereby reducing the vibration of the upper structure. Compared with traditional shock-absorbing devices, the cone-shaped buckle-connected shock-absorbing bearing is composed of an upper cover plate buckled with a lower cover plate through an elastic cushion layer in the middle layer. It has a simple structure, simple installation and operation, low cost, and good shock-absorbing effect. It is more suitable for application and promotion in rural areas where low construction costs are generally required.

[0003] However, the existing technology still has the following problems when it is actually used:

[0004] 1. When the elastic cushion between the upper and lower cover plates is used for a long time, friction will be generated between the upper and lower cover plates and the elastic cushion layer, causing wear of the friction surface material, thereby reducing the stability of the cone-shaped buckled shock-absorbing support, and further reducing the shock-absorbing effect of the entire building.

[0005] 2. It is rather troublesome to manually add oil between the upper and lower cover plates. It is not only time-consuming and labor-intensive, but also impossible to accurately grasp the timing of adding oil. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that the stability of the cone-shaped buckled shock-absorbing support is reduced due to wear caused by friction between the upper and lower cover plates and the elastic cushion layer during long-term use, and to propose a cone-shaped buckled shock-absorbing support with improved long-term stability.

[0032] The functional principle of the utility model can be explained through the following operation modes:

[0033] First, install the cone-shaped buckle-connected shock-absorbing support 8 on the lower connecting plate 9.
