Description

Technical Field

[0001] This utility model relates to the field of bridge bearing technology, specifically to a novel tensile-resistant, high-durability, seismic isolation intelligent rubber bearing. Background Technology

[0002] Bridge bearings are crucial components connecting the superstructure and substructure of a bridge. Their primary function is to provide support, while also accommodating deformations (displacement and rotation) of the bridge superstructure. Bridge bearings are mainly classified into ordinary bearings (plate rubber bearings, pot bearings, and spherical bearings, etc.) and seismic isolation bearings (seismic isolation rubber bearings, friction pendulum seismic isolation bearings, hyperboloid spherical seismic isolation bearings, wire rope seismic isolation bearings, etc.).

[0003] In recent years, the construction and use conditions of bridge bearings have become increasingly stringent, with more and more bearings needing to withstand the dual challenges of bridge construction and environmental conditions. Some bridges, during operation, bear both horizontal and vertical loads while also dealing with vertical tensile forces, which can lead to bridge swaying, and in severe cases, even overturning or damage. Meanwhile, bearings for some bridges built in saltwater lakes or areas with strong winds and sandstorms also require high corrosion resistance.

[0004] While existing rubber bearings possess a certain tensile strength, for bridges requiring high tensile strength, not only must the bearings themselves possess this capability, but their embedded components must also have corresponding capabilities; otherwise, the bearings will not be stable. Furthermore, existing rubber bearings are also unable to withstand highly corrosive environments. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a novel tensile-resistant, high-durability, seismic isolation intelligent rubber bearing.

[0006] The specific technical solution is as follows:

[0007] A novel tensile-resistant, high-durability, seismic isolation intelligent rubber bearing includes a rubber bearing, an upper pad, an upper seat plate, a lower pad, a lower seat plate, an upper anchor rod, and a lower anchor rod. The upper pad and the upper seat plate are sequentially installed on the top of the rubber bearing, and the lower pad and the lower seat plate are sequentially installed on the bottom of the rubber bearing. The upper seat plate is connected to the upper anchor rod of its upper structure, and the lower seat plate is connected to the lower anchor rod of its lower structure.

[0008] Multiple upper tensile rings are fixedly installed on the upper anchor rod, and multiple lower tensile rings are fixedly installed on the lower anchor rod. These measures increase the contact area between the upper and lower anchor rods and the concrete to improve bond strength, thereby enhancing the overall tensile performance of the support.

[0009] The upper seat plate is equipped with sensors for measuring the displacement and pressure of the upper pad plate.

[0010] Optionally, the sensor wires are routed through an opening on the side of the upper pad.

[0011] Optionally, the sensor transmits data to the external monitoring device via wireless communication.

[0012] Optionally, four or eight sensors are arranged around the circumference of the support to monitor the deformation and stress of the rubber support.

[0013] Optionally, a sealing device is provided at the opening location to prevent external substances from entering the pad and affecting the sensor performance.

[0014] Optionally, the surfaces of the upper and lower seat plates are provided with anti-slip textures.

[0015] Optionally, the sensor adopts a detachable connection method, which facilitates replacement when the sensor fails.

[0016] Optionally, the upper and lower seat plates are provided with reinforcing ribs at the points where they connect with the anchor rod.

[0017] Optionally, the edges of the upper and lower pads are provided with protective rounded corners to prevent damage to the edges of the pads due to collisions during installation or use.

[0018] Optionally, the rubber support is configured as a multi-layer rubber structure, with a reinforcing fiber layer between adjacent rubber layers to improve the overall strength and durability of the rubber support.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention increases the contact area between the anchor rods and concrete by setting tensile rings on the upper and lower anchor rods, thereby improving the bond strength and significantly enhancing the overall tensile performance of the bearing. This characteristic allows the seismic isolation rubber bearing to maintain structural stability under large tensile forces, such as strong earthquakes, reducing the risk of damage due to insufficient tensile strength. Sensors for measuring displacement and pressure are installed on the upper pad, enabling real-time monitoring of the bearing's deformation and stress. The sensors transmit data wirelessly, making monitoring more convenient and efficient. This real-time monitoring capability helps to detect potential problems early and improve structural safety.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0026] This utility model provides a novel tensile-resistant, high-durability, seismic-isolation intelligent rubber bearing, referring to... Figure 1 The system includes a rubber bearing 1, an upper pad 2, an upper seat plate 4, a lower pad 3, a lower seat plate 5, an upper anchor rod 6, and a lower anchor rod 8. Among them, the upper pad 2, the upper seat plate 4, the lower pad 3, the lower seat plate 5, the upper anchor rod 6, and the lower anchor rod 8 are all made of special steel and designed, such as weathering steel. This material has excellent corrosion resistance and can be used directly without painting, which improves the durability of the bearing and reduces maintenance costs.

[0027] An upper pad 2 and an upper seat plate 4 are installed sequentially on top of the rubber bearing 1. These two work together to ensure a stable connection between the upper structure and the rubber bearing 1. Similarly, a lower pad 3 and a lower seat plate 5 are installed sequentially on the bottom of the rubber bearing 1 to ensure a firm connection between the lower structure and the rubber bearing 1. The upper seat plate 4 is connected to the upper anchor rod 6 of its upper structure, while the lower seat plate 5 is connected to the lower anchor rod 8 of its lower structure, thereby ensuring a tight connection between the entire bearing system and the building structure.

[0028] To further enhance the tensile strength of the support, multiple upper tensile rings 7 are fixedly installed on the upper anchor rod 6, and multiple lower tensile rings 9 are fixedly installed on the lower anchor rod 8. These tensile rings are designed to increase the contact area between the upper and lower anchor rods 6 and the concrete, thereby improving the bond strength between them. In this way, the overall tensile strength of the support is significantly improved, making it more stable and reliable when facing tensile forces.

[0029] In addition, in order to monitor and evaluate the working status of the rubber bearing 1 in real time, a sensor 10 is specially installed on the upper bearing plate 4. The sensor 10 is used to measure the displacement and pressure of the upper pad plate 2, thereby providing real-time data support for the structural safety of the building. In this way, potential problems can be detected in time and corresponding maintenance measures can be taken to ensure the safety and durability of the building in various environments.

[0030] In summary, the tensile-resistant high-durability seismic isolation rubber bearing 1 of this utility model, through its unique design and component configuration, not only improves the safety performance of buildings under extreme conditions, but also realizes real-time monitoring of the bearing status through sensor 10 technology, providing a strong guarantee for the long-term stable operation of buildings.

[0031] Reference Figure 1 The sensor 10 leads out its sensor wire through an opening on the side of the upper pad 2. During the opening process, the size and position of the opening must be precisely controlled to ensure the sensor wire can be successfully led out without affecting the structural performance of the upper pad 2. A sealing device is provided at the opening, using high-performance sealing materials such as rubber sealing rings, which fit tightly against the opening to prevent external substances (such as dust and moisture) from entering the pad and affecting the performance of the sensor 10.

[0032] In addition to the data transmission methods described above, sensor 10 can also transmit data wirelessly with external monitoring equipment. This communication method avoids complex wiring, reduces the risks associated with messy wiring, and facilitates the placement and adjustment of sensor 10. Sensor 10 uses a detachable connection method, allowing for easy replacement when it malfunctions. Standardized interfaces and operating procedures are used during the disassembly and installation of sensor 10 to ensure no damage to other components and to quickly complete the sensor 10 replacement operation, enabling the monitoring system to resume normal operation as soon as possible.

[0033] Four or eight sensors 10 are arranged around the circumference of the support. This layout can comprehensively and accurately monitor the deformation and stress of the rubber support 1.

[0034] The surfaces of the upper seat plate 4 and the lower seat plate 5 are provided with anti-slip textures. These textures are manufactured using special processing techniques, such as die pressing or machining, to create textures of a certain depth and shape on the surfaces of the upper seat plate 4 and the lower seat plate 5. The anti-slip textures enhance the friction between the upper seat plate 4 and the lower seat plate 5 and other connecting structures, preventing relative sliding between the upper seat plate 4 and the upper structure, and between the lower seat plate 5 and the lower structure, under load, thus further improving the overall integrity and stability of the support.

[0035] Specifically, the upper seat plate 4 and the lower seat plate 5 are equipped with reinforcing ribs at the connection points with the anchor rods. The structure and dimensions of the reinforcing ribs are designed according to the load-bearing capacity of the support. During manufacturing, the reinforcing ribs are connected to the upper seat plate 4 or the lower seat plate 5 as a single unit through casting or welding. The reinforcing ribs enhance the strength of the connection points, making the connection between the upper seat plate 4 and the upper anchor rod 6, and between the lower seat plate 5 and the lower anchor rod 8, more stable and reliable, and capable of withstanding greater tensile and compressive forces.

[0036] The upper pad 2 and lower pad 3 have protective rounded edges to prevent damage to the edges of the pads due to impact during installation or use. During the manufacturing of the upper pad 2 and lower pad 3, the edges are machined into rounded shapes using mechanical processing methods (such as milling and grinding). These protective rounded edges prevent damage to the pad edges due to impact during installation or use. Even in the event of a minor collision or contact during installation, the protective rounded edges can disperse stress, preventing stress concentration at the pad edges that could lead to cracking or damage, thus ensuring the integrity and service life of the upper pad 2 and lower pad 3.

[0037] The rubber bearing 1 is designed with a multi-layered rubber structure, achieved by embedding reinforcing fiber layers between adjacent rubber layers. The main function of these reinforcing fiber layers is to significantly improve the overall strength and durability of the rubber bearing 1. In this way, the rubber bearing 1 can maintain stable performance during heavy loads and long-term use, thereby extending its service life and ensuring structural safety.

[0038] Implementation Principle: Under normal use, this novel tensile-resistant, high-durability, seismic-isolation intelligent rubber bearing 1 primarily functions as a support and seismic isolation unit. The multi-layered rubber structure and reinforcing fiber layer of the rubber bearing 1 effectively isolate vibrations transmitted from the superstructure, reducing the impact of external forces such as earthquakes on the substructure. The upper bearing plate 4, lower bearing plate 5, upper pad 2, and lower pad 3 work together to evenly transfer the load from the superstructure to the rubber bearing 1, which then transfers it to the substructure.

[0039] When a structure is subjected to tensile forces, such as in extreme situations like earthquakes, vertical members may experience significant tensile stress. In this case, the upper tensile ring 7 and lower tensile ring 9 on the upper anchor rod 6 and lower anchor rod 8 come into play. Because the tensile rings increase the contact area between the anchor rod and the concrete, they improve the bond strength, enabling the support to effectively resist tensile forces and preventing failure due to insufficient tensile strength.

[0040] Sensor 10 monitors the displacement and pressure of the upper pad 2 in real time. By arranging sensors 10 circumferentially on the support, the deformation and stress of the rubber support 1 at different locations can be comprehensively monitored. The sensors 10 transmit the collected data to external monitoring equipment via wireless communication. The external monitoring equipment analyzes and processes the data; if any anomalies are detected, such as displacement exceeding a preset threshold or abnormal pressure changes, it can promptly identify potential problems with the support and take appropriate maintenance measures. This helps to detect potential problems early, ensure the safe and reliable operation of the support, and improve the overall structural safety.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
