Description

Technical Field

[0001] The utility model relates to the technical field of damping rubber bearings, and specifically relates to a hybrid high damping rubber bearing. Background Art

[0002] A hybrid high damping rubber bearing is a structural support element used in building structures, bridges or mechanical equipment. It is usually composed of an inner connecting steel plate, a rubber layer and an outer connecting steel plate, and can have good shock absorption effect, flexibility and stability. It can effectively reduce the vibration amplitude of the structure under earthquake, wind load or other external impacts, and protect the safety and stability of the building structure or equipment.

[0003] At present, the inner connecting steel plate of the hybrid high damping rubber bearing is usually of a planar structure, and the planar inner connecting steel plate is prone to stress concentration. When subjected to external loads or vibrations caused by earthquakes, relatively large stresses may be concentrated in some parts of the connecting steel plate, increasing the vulnerability of the structure, reducing the durability, and having relatively limited vertical, horizontal and lateral displacement ranges for the structure. This may limit the displacement ability of the structure under the action of vibrations or other impact forces, reduce the shock absorption effect, and increase the risk of structural damage. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages existing in the prior art, and to propose a hybrid high damping rubber bearing.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A hybrid high damping rubber bearing includes two relatively arranged outer connecting steel plates, a rubber layer is arranged between the two outer connecting steel plates, and multiple layers of inner steel plate groups are arranged in the rubber layer from top to bottom, and rubber filling layers are filled between adjacent upper and lower inner steel plate groups;

[0007] The inner steel plate group includes an inner connecting steel plate, and the inner steel plate group is composed of two symmetrically arranged upper and lower inner connecting steel plates fixedly connected to each other, and the inner connecting steel plate is composed of continuously alternating horizontal plates and arched plates;

[0008] The horizontal plate and the arched plate are integrally formed, and cavities are formed between two relatively arranged upper and lower arched plates in each inner steel plate group;

[0009] As a further description of the above technical solution: the cavities are also filled with rubber filling layers, and the distances between two adjacent arched plates on the left and right are the same.

The inner connecting steel plate is designed into a non-planar structure through continuously alternating horizontal plates and arched plates, which can increase the support area, enabling the bearing to more evenly disperse the pressure when bearing external forces, reducing the risk of excessive local stress on the bearing, and improving the stability and seismic resistance of the bearing.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-3, a hybrid high-damping rubber bearing, includes two oppositely arranged outer connecting steel plates 1, and a plurality of mounting holes 6 are formed on the surfaces of the outer connecting steel plates 1. A rubber layer 2 is provided between the two outer connecting steel plates 1, and multiple inner steel plate groups 3 are arranged in the rubber layer 2 from top to bottom. The inner steel plate group 3 includes inner connecting steel plates 31. The inner steel plate group 3 is composed of two symmetrically arranged upper and lower inner connecting steel plates 31 fixedly connected to each other. The inner connecting steel plate 31 is composed of continuously alternating horizontal plates 311 and arched plates 312, and the distances between two adjacent arched plates 312 on the left and right are the same. The horizontal plate 311 and the arched plate 312 are integrally formed, and cavities 32 are formed between two oppositely arranged upper and lower arched plates 312 in each inner steel plate group 3.

[0023] In this embodiment, the inner connection structure of the hybrid high-damping rubber bearing is improved. The inner connecting steel plate 31 is designed into a non-planar structure through continuously alternating horizontal plates 311 and arched plates 312, which can increase the support area, enable the bearing to disperse pressure more evenly when bearing external forces, reduce the risk of excessive local stress on the bearing, and improve the stability and seismic resistance of the bearing. And it provides multi-directional shock absorption effect. By cooperating with each other in the horizontal, vertical and transverse directions, it can effectively reduce the structural displacement and deformation caused by earthquakes or other vibrations.

[0024] The inner steel plate group 3 composed of the inner connecting steel plates 31 is further improved in the overall structural performance. The design of the cavity 32 can increase the deformation ability of the rubber bearing, enable it to better absorb the displacement caused by earthquakes or other external impact forces, provide a larger extrusion space, enable the bearing to give full play to its shock absorption and buffering functions, and reduce the risk of structural stress and damage.

[0025] Among them, the cross-section of the arched plate 312 is semi-circular, triangular or trapezoidal. The design of these shapes can optimize the stress characteristics, shock absorption effect, energy absorption performance and stability of the bearing, thereby improving the overall performance and safety of the bearing.

[0026] Embodiment 2

[0027] Based on the above embodiment, this embodiment is a further improvement on the basis of Embodiment 1. Compared with Embodiment 1, a rubber filling layer 4 is filled between the upper and lower adjacent inner steel plate groups 3, and the cavity 32 is also filled with the rubber filling layer 4.

[0028] The rubber filling layer 4 can form a buffer layer between the inner steel plate groups 3, enabling the bearing to have better shock absorption and buffering effects. Rubber has good elasticity and energy absorption performance, and can effectively absorb the energy caused by earthquakes or other external impacts, reducing the vibration amplitude of the structure.

[0029] In addition, the rubber filling layer 4 can reduce the direct contact between the inner steel plate groups 3, reduce the transmission of vibration and impact, avoid excessive stress concentration on the bearing, and increase the durability and safety of the structure.

[0030] In addition, a number of uniformly distributed protrusions 5 are provided on the outer surface of the inner connecting steel plate 31. The contact area between the inner connecting steel plate 31 and the rubber filling layer 4 is increased to achieve better bonding and connection effects.

[0031] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
