Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to a stable and seismic-resistant bearing for bridge engineering. Background Technology

[0002] Seismic bearings are structural elements used to resist seismic forces and deformations. Located at the bearing positions of bridges, they play a vital role in bridge engineering, helping to protect the stability and safety of the bridge structure. The working principle of seismic bearings is based on elastic and damping characteristics. They are typically composed of springs or rubber pads, along with additional dampers or friction materials. Under earthquakes or loads, seismic bearings will displace and deform, reducing the impact of seismic forces on the bridge by providing flexible support.

[0003] Utility model patent CN 219364304 U discloses a bridge seismic bearing, including a device base, a bearing body at the top of the device base, a bottom limiting groove inside the bearing body, a buffer rubber pad installed in the middle of the bottom limiting groove, a top fixing groove at the top of the buffer rubber pad, a bottom connecting column at the top of the top fixing groove, an upper connecting column at the top of the bottom connecting column, an upper body at the top of the upper connecting column, a top mounting seat at the top of the upper body, and a spring tension shaft inside the bearing body. This utility model's bridge seismic bearing, by utilizing the interlocking limiting groove in conjunction with the bottom and upper connecting columns, provides offset space for the device components when the device shifts due to bridge vibration. The spring tension shaft, in conjunction with the connecting piece, connects the bearing body and the upper body while simultaneously limiting their position through tension.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that the buffer rubber pad of the device lacks a protective device. The rubber buffer pad will fade, harden and crack when exposed to sunlight for a long time, reducing the buffering effect of the rubber buffer pad. Extreme weather such as heavy rain and freezing will also damage the rubber material, reduce the service life of the rubber buffer pad and require frequent replacement, which is time-consuming and laborious.

[0005] Therefore, it is necessary to invent a bridge engineering stability and seismic-resistant bearing to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to address the problem that existing seismic bearings lack protective devices for the buffer rubber pads, which can damage the rubber material in extreme weather conditions such as heavy rain and freezing, reducing the service life of the rubber buffer pads and requiring frequent, time-consuming, and labor-intensive replacements. The invention provides a stable seismic bearing for bridge engineering.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: it includes a support assembly and a protective mechanism. The protective mechanism is disposed on the support assembly. The support assembly includes a lower steel base, a buffer rubber pad, and an upper steel base. The buffer rubber pad is disposed between the lower steel base and the upper steel base, and the three are connected and fixed by screws. The protective mechanism includes a sliding buffer groove, a sliding groove, a protective steel plate, and a side plate. Four sliding buffer grooves are provided, and the four sliding buffer grooves are respectively provided at the edges of the bottom surface of the upper steel base. Four sliding grooves are provided, and the four sliding grooves are provided at the edges of the top surface of the lower steel plate. The protective steel plate is slidably disposed between the sliding buffer grooves and the sliding grooves. The side plate is fixedly connected to one side of the protective steel plate.

[0008] As a further description of the above technical solution, the sliding buffer groove and the protective steel plate are matched in size and position with the sliding groove, and a certain buffer space is left between the top of the protective steel plate and the sliding buffer groove.

[0009] As a further description of the above technical solution, the protective mechanism also includes a magnetic block and a handle. The magnetic block is fixedly disposed on the surface of the side plate near the protective plate, and the handle is fixedly connected to the side plate away from the protective plate.

[0010] As a further description of the above technical solution, the support assembly also includes a lower limiting steel ring and an upper limiting steel ring. The lower limiting steel ring is fixedly connected above the lower steel base and fits and surrounds the bottom of the buffer rubber pad. The upper limiting steel ring is fixedly connected below the upper steel base and fits and surrounds the top of the buffer rubber pad.

[0011] As a further description of the above technical solution, the support assembly also includes a connecting seat and a connecting bolt. The connecting seat is located above the upper steel seat and is connected to the upper steel seat by a screw. The connecting bolt is fixedly connected to the upper part of the connecting seat.

[0012] As a further description of the above technical solution, the support assembly also includes a fixing bolt, which is threadedly connected to and passes through the lower steel seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a protective mechanism that allows operators to push the protective steel plate into the sliding groove and sliding buffer groove during seismic bearing installation. The magnetic block is attracted to the lower and upper steel bases. The surrounding protective plates protect the buffer rubber pad, preventing prolonged exposure to direct sunlight or rain, thus avoiding corrosion and damage and extending its lifespan. Furthermore, when the bridge is subjected to lateral tension, the sliding groove and sliding buffer groove provide lateral support to the seismic bearing by limiting the steel plate, ensuring bridge stability and seismic performance. When the buffer rubber pad needs replacement, the operator pulls the handle to disengage the magnetic block from the lower and upper steel plates and pulls the protective plate out of the sliding groove for replacement. This design is highly convenient and practical. Attached Figure Description

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0024] like Figure 1 — Figure 5 As shown, the bridge engineering stable seismic bearing includes a bearing assembly 1 and a protective mechanism 2, with the protective mechanism 2 installed on the bearing assembly 1.

[0025] like Figure 2-3 As shown in this disclosure, the support assembly 1 includes a lower steel base 11, a buffer rubber pad 13, an upper steel base 15, a lower limiting steel ring 12, an upper limiting steel ring 14, a connecting seat 16, a connecting bolt 17, and a fixing bolt 18. The buffer rubber pad 13 is disposed between the lower steel base 11 and the upper steel base 15, and the three are connected and fixed by a screw. The lower limiting steel ring 12 is fixedly connected above the lower steel base 11 and fits and surrounds the bottom of the buffer rubber pad 13. The upper limiting steel ring 14 is fixedly connected below the upper steel base 15 and fits and surrounds the top of the buffer rubber pad 13. The connecting seat 16 is located above the upper steel base 15 and is connected to the upper steel base 15 by a screw. The connecting bolt 17 is fixedly connected above the connecting seat 16. The fixing bolt 18 is threadedly connected to the lower steel base 11 and passes through the lower steel base 11.

[0026] Therefore, operators can connect and fix the support to the pier using fixing bolt 18, connect and fix the straight support to the bridge body using connecting bolt 17, and use rubber buffer pads to buffer and resist earthquakes on the bridge.

[0027] like Figure 4-5 As shown, in a preferred embodiment, the protective mechanism 2 includes a sliding buffer groove 21, a sliding groove 22, a protective steel plate 23, a side plate 24, a magnetic block 25, and a handle 26. Four sliding buffer grooves 21 are provided, each located at the edge of the bottom surface of the upper steel base 15. Four sliding grooves 22 are provided, each located at the edge of the top surface of the lower steel plate. The protective steel plate 23 is slidably disposed between the sliding buffer grooves 21 and 22. The side plate 24 is fixedly connected to one side of the protective steel plate 23. The sliding buffer grooves 21, 23, and 22 are matched in size and position, and a certain buffer space is left between the top of the protective steel plate 23 and the sliding buffer groove 21. The magnetic block 25 is fixedly disposed on the surface of the side plate 24 near the protective plate. The handle 26 is fixedly connected to the side plate 24 away from the protective plate.

[0028] Therefore, when installing the seismic bearing, the operator pushes the handle 26 to push the protective steel plate 23 into the sliding groove 22 and the sliding buffer groove 21 until the magnetic block 25 is attracted to the lower steel seat 11 and the upper steel seat 15. The buffer rubber pad 13 is protected by the surrounding protective plates. When the bridge is subjected to lateral tension, the sliding groove 22 and the sliding buffer groove 21 can limit the steel plate to provide lateral support for the seismic bearing. When the buffer rubber pad 13 needs to be replaced, the operator pulls the handle 26 to disengage the magnetic block 25 from the lower and upper steel plates and pulls the protective plate out of the sliding groove 22 to carry out the subsequent replacement operation.

[0029] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
