Description

Technical Field

[0001] This utility model relates to the field of rubber bearing technology, and in particular to a waterproof rubber bearing. Background Technology

[0002] Most existing rubber bearings have seismic isolation functions. Their installation method involves fixing the lower part of the steel plate component to the foundation, while the upper part is connected to the superstructure. During an earthquake, the lead-core column located between the upper and lower layers of the steel plate effectively absorbs the energy generated by the earthquake through plastic deformation, thereby reducing the impact of the earthquake on the superstructure and achieving excellent seismic isolation. Furthermore, the lead-core column is tightly wrapped with rubber protective units, providing it with additional protection.

[0003] However, the aforementioned rubber bearings have shortcomings in terms of waterproof protection. For example, in rainy weather or in environments with high humidity, the outer surface of the rubber protective unit is prone to absorbing rainwater and water molecules from the air. Over time, water droplets may condense on its surface. These water droplets may contain substances that are harmful to the rubber protective unit, thereby increasing the risk of corrosion and potentially affecting the overall service life of the rubber bearing.

[0048] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] Example 1

[0050] As attached Figure 1-4 As shown, this embodiment discloses a waterproof rubber support to reduce the risk of corrosion of a rubber protective unit (not shown in the figure). It mainly includes a protective component 2, a lead core column 5, and a steel plate component 1. In use, external water molecules first come into contact with the hydrophobic unit 24 in the protective component 2; then, several water molecules converge into visible water droplets; subsequently, the water droplets slide down the outer wall of the hydrophobic unit 24 onto the steel plate component 1. During this process, external water molecules do not come into contact with the rubber protective unit, reducing the risk of corrosion. When a large number of water droplets accumulate on the steel plate component 1, some of the droplets flow along the slope 15 on the steel plate component 1, gradually moving away from the present invention. This design further reduces the risk of corrosion of the rubber protective unit.

[0051] The specific structure of the waterproof rubber bearing is as follows: it includes a protective component 2, with a rubber protective unit surrounding the interior of the protective component 2, and a hydrophobic unit 24 surrounding the outer periphery of the rubber protective unit. Steel plate components 1 are symmetrically arranged on both sides of the protective component 2. A lead core column 5 is provided on the steel plate component 1, and the rubber protective unit is surrounded by the lead core column 5. A slope 15 is formed on the steel plate component 1, meaning that the thickness of a portion of the edge structure of the steel plate component 1 gradually increases to the thickness of its main structure. A certain distance exists between the slope 15 and the protective component 2. Compared with the prior art, this utility model reduces the risk of corrosion of the rubber protective unit and extends the overall service life of the rubber bearing to a certain extent, thus possessing high practicality.

[0052] In a specific application scenario, as shown in the appendix Figure 1 and appendix Figure 2 As shown, the ramp 15 is triangular in shape; furthermore, the thickness of the edge of the ramp 15 gradually increases to the thickness of the main structure of the steel plate component 1. In use, the triangular ramp 15 can quickly drain water accumulated on the steel plate component 1 to the outside of this embodiment, thereby reducing the probability of corrosion of the rubber protective unit to a certain extent.

[0053] Furthermore, the slope of ramp 15 is provided with a hydrophobic layer (not shown in the figure), which improves the efficiency of the aforementioned water discharge.

[0054] In a specific application scenario, as shown in the appendix Figure 3 As shown, the protective component 2 is provided with a protective lead core unit 21; wherein, the protective lead core unit 21 is directly or indirectly arranged around the periphery of the lead core column 5, the outer wall of the protective lead core unit 21 is directly or indirectly connected to the inner wall of the aforementioned rubber protective unit, and the side of the protective lead core unit 21 near the lead core column 5 is connected to the steel plate component 1. This design reduces the probability of the lead core column 5 being damaged by external foreign objects.

[0055] Furthermore, a polyurethane coating unit 22 is provided between the aforementioned protective lead core unit 21 and the hydrophobic unit 24; specifically, the polyurethane coating unit 22 is arranged around the periphery of the protective lead core unit 21, and the outer wall of the polyurethane coating unit 22 is directly or indirectly connected to the inner wall of the rubber protective unit; wherein, the polyurethane coating unit 22 has the ability to buffer and be elastic. When the earthquake intensity is large, the lead core column 5 may sway inside the protective component 2; in this process, the polyurethane coating unit 22 can effectively absorb the force generated by the swaying of the lead core column 5. This design reduces the impact of this force on the superstructure and, to a certain extent, enhances the seismic isolation effect of this embodiment.

[0056] Furthermore, a waterproof unit 23 is provided between the polyurethane coating unit 22 and the rubber protective unit; specifically, the waterproof unit 23 is arranged around the periphery of the polyurethane coating unit 22, and the outer wall of the waterproof unit 23 is connected to the inner wall of the rubber protective unit. This design can reduce the probability of the lead core column 5 coming into contact with external water molecules, thereby reducing the risk of corrosion of the lead core column 5 and extending the service life of this embodiment.

[0057] It should be noted that: Figure 3 The upper structure of the protective component 2 is only the upper structure; the lower structure of the protective component 2 is symmetrically arranged with the upper structure, that is, the upper structure of the protective component 2 is the same as its lower structure; in addition, there are two lead core columns 5 in this embodiment, one is arranged on the upper structure of the protective component 2 and the other is arranged on the lower structure of the protective component 2. This design makes it convenient for the protective component 2 to be connected to both the upper steel plate component 1 and the lower steel plate component 1 at the same time.

[0058] In a specific application scenario, as shown in the appendix Figure 1 and appendix Figure 2As shown, the steel plate component 1 mainly includes a connecting steel plate 11 and connecting bolts 12; wherein, the connecting steel plate 11 is directly or indirectly connected to the side of the waterproof unit 23 on the side near the protective component 2; a number of connecting bolts 12 are provided on the connecting steel plate 11. This design facilitates the connection of this embodiment with the superstructure or foundation, and enhances the overall structural stability of this embodiment.

[0059] Example 2

[0060] As attached Figure 2 and appendix Figure 4 As shown, this embodiment discloses a waterproof rubber support for improving the sealing performance of Embodiment 1. In addition to the components in Embodiment 1, it also includes: a sealing slot 13, a sealing plate 14, and a sealing frame 25. The sealing slot 13 and the sealing frame 25 cooperate to allow the protective member 2 to be more tightly connected to the steel plate member 1, thereby improving the sealing performance between the protective member 2 and the steel plate member 1. The sealing plate 14 can further improve the sealing performance of the connection between the protective member 2 and the steel plate member 1.

[0061] In a specific application scenario, the sealing slot 13 is located on the side of the connecting steel plate 11 opposite to the protective member 2; a sealing plate 14 is provided on the side of the sealing slot 13 near the protective member 2, and the side of the sealing plate 14 near the protective member 2 is connected to the end of the lead core column 5; of course, workers can make openings as shown in the appendix on the side of the connecting steel plate 11 near the protective member 2. Figure 2 The sealing slot 13 shown can be used as long as it meets one's own needs; in addition, the aforementioned waterproof unit 23 is provided with a sealing frame 25 on the side near the connecting steel plate 11, and the sealing frame 25 is adapted to the sealing slot 13.

[0062] Example 3

[0063] As attached Figure 4 As shown, this embodiment discloses a waterproof rubber support to improve the stability of the overall structure of Embodiment 2. In addition to the components in Embodiment 2, it also includes an internal filling plate 3, which is disposed on the inner wall of the protective lead core unit 21. This design can stabilize the positional relationship between the lead core column 5 and the protective lead core unit 21.

[0064] In a specific application scenario, the inner filling plate 3 has an installation hole 4 on the side near the steel plate component 1, and the inner wall of the installation hole 4 is connected to the outer wall of the lead core column 5.

[0065] Furthermore, the lead core column 5 is threadedly connected to the internal filling plate 3. This design facilitates the disassembly of the lead core column 5, which to some extent reduces the workload of the staff and improves work efficiency.
