Description

Technical Field

[0001] This application relates to the technical field of building base isolation, and particularly to a damping isolation rubber bearing. Background Art

[0002] Currently, most building base isolation systems apply a combination of ordinary laminated rubber bearings and lead - core rubber bearings. The lead - core bearing is a damping - type bearing formed by adding a lead core with an appropriate diameter to the middle of an ordinary laminated rubber bearing (as shown in Figure 5 ), which uses the elastoplastic properties of the lead core during ground motion to dissipate seismic energy. However, since lead is a heavy metal, it is easy to pollute the environment during the manufacturing and use of lead - core rubber bearings. Therefore, the present invention proposes a damping isolation rubber bearing. Summary of the Invention

[0003] The embodiments of this application provide a damping isolation rubber bearing, which can replace the lead core to supply damping for the ordinary laminated rubber bearing for shock absorption, achieving the purpose of environmental protection.

[0004] In view of this, this application provides a damping isolation rubber bearing, including: a laminated rubber bearing body and a tooth core;

[0005] The tooth core includes a bottom cover, a housing, and a soft elastic material filled in the housing;

[0006] The housing is fixed on the bottom cover, and a ring - tooth structure is formed around the housing;

[0007] An installation hole matching the shape of the tooth core is opened at the center of the laminated rubber bearing body;

[0008] The tooth core is arranged in the installation hole, and one end of the tooth core is fixedly connected to the laminated rubber bearing body through the bottom cover.

[0009] Optionally, multiple columns of the ring - tooth structure are formed along the circumferential direction on the outer surface of the housing.

[0010] Optionally, every two adjacent columns of the ring - tooth structure are stagger - arranged.

[0011] Optionally, the cross - section of the housing is U - shaped;

[0012] The bottom of the housing is embedded in the bottom cover and fixedly connected to the bottom cover.

[0013] Optionally, the laminated rubber bearing body includes an upper sealing plate, a lower sealing plate, and a rubber layer arranged between the upper sealing plate and the lower sealing plate.

[0014] Optionally, the tooth core is fixedly connected to the lower sealing plate through the bottom cover.

[0015] Optionally, a reinforcing plate for enhancing the compressive capacity of the rubber layer is provided in the middle of the rubber layer.

[0016] Optionally, the reinforcing plate is made of steel.

[0017] Optionally, the housing is made of mild steel or copper.

[0018] Optionally, the soft elastic material is rubber.

[0019] As can be seen from the above technical solutions, the embodiments of the present application have the following advantages: including a laminated rubber bearing body and a tooth core. The tooth core includes a bottom cover, a housing, and a soft elastic material filled in the housing. The housing is fixed on the bottom cover, and a ring tooth structure is formed around the housing. An installation hole matching the shape of the tooth core is provided in the center of the laminated rubber bearing body. The tooth core is arranged in the installation hole, and one end of the tooth core is fixedly connected to the laminated rubber bearing body through the bottom cover. Since the tooth core is only fixed at one end of the laminated rubber bearing body, relative movement is formed between the laminated rubber bearing body and the tooth core during the horizontal shear deformation process, and it is necessary to overcome the interfacial friction force and the elastic resistance of the ring tooth structure of the tooth core to slide, thereby dissipating seismic energy. This damping and seismic isolation rubber bearing is more environmentally friendly by using a tooth core instead of a lead core, and at the same time has a low manufacturing cost.

[0030] This application provides an embodiment of a damping isolation rubber bearing. For details, please refer to Figures 1 to 4 。

[0031] The damping isolation rubber bearing in this embodiment includes: a laminated rubber bearing body and a tooth core 1. The tooth core 1 includes a bottom cover 11, a shell 12, and a soft elastic material 13 filled in the shell 12. The shell 12 is fixed on the bottom cover 11, and a ring tooth structure 121 is formed around the shell 12; an installation hole matching the shape of the tooth core 1 is opened in the center of the laminated rubber bearing body. The tooth core 1 is arranged in the installation hole, and one end of the tooth core 1 is fixedly connected to the laminated rubber bearing body through the bottom cover 11.

[0032] It should be noted that: since the tooth core 1 is only fixed at one end of the laminated rubber bearing body, relative movement is formed between the laminated rubber bearing body and the tooth core 1 during the horizontal shear deformation process, and it is necessary to overcome the interfacial friction force and the elastic resistance of the ring tooth structure 121 of the tooth core 1 to slide, thereby dissipating seismic energy. This damping isolation rubber bearing is more environmentally friendly by using the tooth core 1 instead of the lead core, and at the same time has a low manufacturing cost.

[0033] The above is the first embodiment of a damping isolation rubber bearing provided by the present application. The following is the second embodiment of a damping isolation rubber bearing provided by the present application. For details, please refer to Figures 1 to 4 .

[0034] The damping isolation rubber bearing in this embodiment includes: a laminated rubber bearing body and a tooth core 1. The tooth core 1 includes a bottom cover 11, a housing 12, and a soft elastic material 13 filled in the housing 12. The housing 12 can provide rigidity for the tooth core 1 in tension and compression. The soft elastic material 13 filled in the housing 12 can provide elasticity for shear deformation and compression deformation ability for the tooth core 1. The bottom cover 11 is used to fix the tooth core 1 and is the tensile node of the tooth core 1. The housing 12 is fixed on the bottom cover 11, and a ring tooth structure 121 is formed around the housing 12. An installation hole matching the shape of the tooth core 1 is opened in the center of the laminated rubber bearing body. The tooth core 1 is arranged in the installation hole, and one end of the tooth core 1 is fixedly connected to the laminated rubber bearing body through the bottom cover 11.

[0035] Specifically, multiple rows of ring tooth structures 121 are formed along the circumferential direction on the outer surface of the housing 12, making it have manufacturability and assemblability with the installation hole on the laminated rubber bearing body.

[0036] Every two adjacent rows of ring tooth structures 121 are arranged staggeredly. Through the staggering design, the impact force during the sliding process can be avoided.

[0037] The cross-section of the housing 12 can be U-shaped. The bottom of the housing 12 is embedded in the bottom cover 11 and fixedly connected to the bottom cover 11.

[0038] The laminated rubber bearing body includes an upper sealing plate 2, a lower sealing plate 3, and a rubber layer 4 arranged between the upper sealing plate 2 and the lower sealing plate 3. A reinforcing plate 5 for enhancing the compressive capacity of the rubber layer 4 is arranged in the middle of the rubber layer 4. The upper sealing plate 2, the lower sealing plate 3, the reinforcing plate 5, and the rubber layer 4 are vulcanized together. It can be understood that the rubber layer 4 can be damping rubber or natural rubber.

[0039] Specifically, the tooth core 1 is fixedly connected to the lower sealing plate 3 through the bottom cover 11. The material of the reinforcing plate 5 can be steel. The material of the housing 12 can be mild steel or copper. It can be understood that the housing 12 has a certain soft elastic deformation ability, and because the housing 12 has a certain rigidity in the vertical direction, it can withstand the corresponding tensile force. The housing 12 and the soft elastic material 13 filled in the housing 12 cooperate to dissipate energy, making the bearing have a certain damping. The soft elastic material 13 can be rubber. Because rubber has a certain soft elasticity, it can be compressed and deformed and shear deformed in the horizontal direction.

[0040] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
