Description

Technical Field

[0001] The utility model belongs to a bridge support, in particular to a waterproof and durable rubber support body structure. Background Art

[0002] Bridge bearings are crucial components connecting the superstructure and substructure of a bridge. They reliably transmit the reaction forces and deformations of the superstructure to the substructure, and their performance directly impacts the safety and lifespan of the bridge. Compared to steel bearings, rubber bearings offer a number of advantages, including simpler structure, easier fabrication, lower cost, and easier installation. They also provide vibration damping and isolation, making them widely used in bridge engineering. During use, rubber bearings are exposed to the elements, including ozone, ultraviolet rays, hot air, and corrosion from acids, alkalis, and oils. Furthermore, some water-crossing routes are prone to water immersion, which can lead to rubber aging and a decrease in its physical and mechanical properties. This can cause fine cracks to form on the bearing surface, shortening its service life and impacting its durability. In severe cases, the bearings may need to be replaced. Bearing replacement requires significant manpower and resources, sometimes even requiring traffic disruptions. This wastes significant resources and inconveniences people face.

[0003] For the above reasons, those skilled in the art urgently need to develop a bridge bearing with waterproofing capabilities that effectively extends the service life of the bridge bearing through structural optimization to address the short service life of existing bridge bearings. The applicant has not found any patent literature reports identical or similar to the present utility model in the domestic patent database. Summary of the Invention

[0004] The utility model provides a waterproof and durable rubber bearing body structure, which can effectively solve the problem of short service life of existing bridge bearings caused by external factors during use.

[0005] The overall technical concept of the utility model is:

[0006] The waterproof and durable rubber bearing body structure includes a rubber layer and stiffening steel plates arranged horizontally and spaced longitudinally within the rubber layer; a waterproof and durable rubber sleeve is vulcanized and fixed to the exposed surface of the body structure, and the exposed surface includes the side surface of the body structure; or the side surface, top surface and / or bottom surface of the body structure.

[0007] The specific technical structure of the utility model is:

[0008] In order to facilitate the relative sliding function of the present invention after being applied to the bridge support, the preferred technical implementation method is that a slide plate is provided on the outer surface of the waterproof and durable rubber sleeve on the outside of the exposed top or bottom surface of the main body structure, and a waterproof and durable rubber sleeve is vulcanized and fixed on the exposed side surface of the main body structure and the outside of the top or bottom surface where the slide plate is not provided.

[0009] In order to facilitate the relative sliding of the adjacent surfaces of the bridge support superstructure and the main body structure, meet the functional requirements of the sliding rubber bearing, avoid the erosion of the sliding steel plate and the slide plate by the external environment, and enhance the external protection of the waterproof and durable rubber sleeve, a more preferred technical implementation method is that the slide plate is set on the outer surface of the waterproof and durable rubber sleeve outside the exposed top surface of the main body structure, the stainless steel plate is set on the surface of the slide plate and the adjacent surfaces of the two constitute a friction pair, a sliding steel plate is set on the outside of the stainless steel plate, and a protective cover is fixed to the outside of the sliding steel plate. In order to facilitate the assembly of the protective cover, a more preferred technical implementation method is that the top of the protective cover is fixed to the outside of the sliding steel plate by bolts. The material of the protective cover is preferably stainless steel.

[0010] In order to facilitate the application of the present invention to high-damping rubber bearings, the preferred technical implementation method is that the main body structure also includes an upper sealing steel plate and a lower sealing steel plate respectively provided on its top and bottom surfaces. The upper steel plate is fixed to the outer surface of the upper sealing steel plate, and the lower steel plate is fixed to the outer surface of the lower sealing steel plate. A through hole for accommodating a positioning rod is provided longitudinally within the main body structure; and a waterproof and durable rubber sleeve is fixed to the exposed side of the main body structure by vulcanization. Because high-damping bearings have relatively high damping force requirements and strict requirements on the distribution of the stiffening steel plate and rubber layer, a positioning rod needs to be provided in the through hole of the main body structure during vulcanization. After vulcanization positioning, the positioning rod is removed from the through hole. The rubber rod can eventually be inserted into the through hole for aesthetics and sealing.

[0011] To facilitate the application of the present invention in lead-rubber bearings, the preferred technical implementation method is that the main structure also includes an upper sealing steel plate and a lower sealing steel plate on its top and bottom surfaces, respectively. The upper steel plate is fixed to the outer surface of the upper sealing steel plate, and the lower steel plate is fixed to the outer surface of the lower sealing steel plate. The lead core is longitudinally disposed within the main structure; the exposed side of the main structure is vulcanized and fixed with a waterproof and durable rubber sleeve. During vulcanization of the lead core bearing, a positioning rod is inserted through the lead core hole. After vulcanization is complete, the positioning rod is removed and the lead core is inserted during bearing installation.

[0012] To facilitate the manufacture and assembly of parts, the preferred technical implementation means is that the upper steel plate is fixed to the outer surface of the upper sealing layer steel plate by bolts, and the lower steel plate is fixed to the outer surface of the lower sealing layer steel plate by bolts.

[0013] To ensure that the waterproof and durable rubber sleeve better meets the requirements of aging resistance and ease of manufacture, the preferred technical implementation method is to use chlorosulfonated polyethylene rubber as the material for the waterproof and durable rubber sleeve. Chlorosulfonated polyethylene is made from low-density polyethylene or high-density polyethylene through chlorination and chlorosulfonation reactions. It is a white or yellow elastomer that is soluble in aromatic hydrocarbons and chlorinated hydrocarbons but insoluble in fats and alcohols. It can only swell but not dissolve in ketones and ethers. It has excellent ozone resistance, atmospheric aging resistance, chemical corrosion resistance, etc., and good physical and mechanical properties, aging resistance, heat and low temperature resistance, oil resistance, flame resistance, wear resistance, and electrical insulation resistance. Because this material is an existing material, the applicant will not elaborate on it.

[0014] In the description of the present invention, the terms "side", "top", "bottom", "horizontal", "longitudinal", "outer side", "bottom", "outer surface", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of simplifying the description of the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0015] The technical advancements achieved by this utility model are:

[0016] 1. The utility model adopts a structural design in which a waterproof and durable rubber sleeve is vulcanized on the exposed surface of the main body structure. Firstly, it slows down the aging speed of the rubber layer due to factors such as ozone, ultraviolet rays, hot air, rain, acid, alkali and oil erosion, thereby extending the service life of the support; secondly, it makes the rubber layer more tightly combined with the main body structure and not easy to fall off, while having a better protective effect.

[0017] 2. The utility model adopts a structural design in which a slide plate is provided on the outer surface of the waterproof and durable rubber sleeve outside the exposed top or bottom surface of the main body structure, which can better meet the realization of the relative sliding function of the utility model after being applied to the bridge support.

[0018] 3. The utility model adopts a structural design in which a protective cover is fixed on the outside of the sliding steel plate. Firstly, it effectively prevents the external environment from corroding the sliding steel plate and the sliding plate; secondly, it enhances the external protection of the waterproof and durable rubber sleeve.
