Description

Technical Field

[0001] This utility model relates to the field of bridge engineering technology, specifically to a bridge bearing used in bridge engineering. Background Technology

[0002] Bridge bearings are important structural components that connect the superstructure and substructure of a bridge. Located between the bridge and the bearing pad, they reliably transfer the loads and deformations (displacement and rotation) borne by the superstructure to the substructure. They are important force transmission devices for bridges. Bridges generally refer to structures built over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly.

[0003] Existing bridge bearings have limited load-bearing capacity and deformation range due to the limited internal rubber bearings, resulting in poor performance and reduced safety of bridges. This diminishes the practicality of bridge bearings. Therefore, we propose a new type of bridge bearing for bridge engineering. Utility Model Content

[0004] The purpose of this invention is to provide a bridge bearing for bridge engineering to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge bearing for bridge engineering, comprising a support assembly, a top frame, a buffer assembly, and a connecting assembly. The top frame is provided at the top of the support assembly, and connecting assemblies are provided at the middle of both sides of the top frame. Buffer assemblies are provided on both sides inside the support assembly. The connecting assembly includes a frame plate, a first fastener, a sliding plate, a second fastener, and a sliding groove. The first fastener is provided at both ends of the frame plate, a sliding plate is provided on the end side of the frame plate, a second fastener is provided on one side of the bottom end of the sliding plate, and a sliding groove is provided on the other side of the bottom end of the sliding plate.

[0006] Furthermore, the frame plate is arc-shaped, and the frame plate is connected to the top frame in a threaded structure by a first fastener.

[0007] Furthermore, the frame plate and the slide plate are connected by threads, and the slide plate and the groove are connected by sliding.

[0008] Furthermore, the buffer assembly includes a support cylinder, a connecting rod, and a buffer spring, with the connecting rod provided at the top of the support cylinder and the buffer spring provided on the side of the connecting rod.

[0009] Furthermore, the support cylinder and the connecting rod are sleeve-shaped, and the connecting rod is connected to the buffer spring.

[0010] Furthermore, the support assembly includes a first bearing seat, a first side ring, a limiting block, and a buffer seat, wherein the first bearing seat is provided with a first side ring on its side, the first bearing seat is provided with a limiting block at its top, and the limiting block is provided with a buffer seat on its side.

[0011] Furthermore, the top frame includes a second support seat and a second side ring, and the second support seat is provided with a second side ring on its side.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the support cylinder is set on both sides inside the support, and the top is fitted by a buffer spring, so that the buffer seat in the middle of the bridge support reduces the force on the buffer seat when it is under force. The side frame plate is arc-shaped and is installed on the side ring of the bridge support by the first fastener and the second fastener to protect the gap part of the support. When the support is under force, the second side ring will slide along the track of the slide groove through the frame plate and the slide plate. At the same time, there is a certain gap between the bottom of the slide groove and the slide plate to avoid excessive internal force and deformation due to constraint, which would lead to structural damage.

[0013] The support cylinders are installed on both sides inside the bearing, and the support cylinders are sleeved with the connecting rods. At the same time, the top is fitted by a buffer spring, so that when the buffer seat in the middle of the bridge bearing is under force, the stress on the buffer seat is reduced and the service life of the bearing is extended.

[0014] The first and second fasteners are installed on the side rings of the bridge bearing. The gap between the upper and lower side rings is covered by the frame plate, which protects the bearing from external dust, insects and birds, thus effectively protecting the bridge bearing.

[0019] like Figure 1-2 As shown, a bridge bearing for bridge engineering includes a support assembly 1, a top frame 2, a buffer assembly 3, and a connecting assembly 4. The top frame 2 is provided at the top of the support assembly 1, and the connecting assembly 4 is provided at the middle of both sides of the top frame 2. The buffer assembly 3 is provided on both sides inside the support assembly 1. The buffer assembly 3 includes a support cylinder 301, a connecting rod 302, and a buffer spring 303. The connecting rod 302 is provided at the top of the support cylinder 301, and the buffer spring 303 is provided on the side of the connecting rod 302. The support cylinder 301 and the connecting rod 302 are sleeve-shaped, and the connecting rod 302 and the buffer spring 303 are connected. The support cylinder 301 is provided on both sides inside the bearing, while the support... The cylinder 301 and the connecting rod 302 are sleeved together, and the top is fitted by a buffer spring 303, so that when the buffer seat 104 in the middle of the bridge support is subjected to force, the force on the buffer seat 104 is reduced and the service life of the support is extended. The support component 1 includes a first bearing seat 101, a first side ring 102, a limiting block 103, and a buffer seat 104. The first bearing seat 101 is provided with a first side ring 102 on its side, and a limiting block 103 is provided at the top of the first bearing seat 101. The buffer seat 104 is provided on the side of the limiting block 103. The top frame 2 includes a second bearing seat 201 and a second side ring 202. The second bearing seat 201 is provided with a second side ring 202 on its side.

[0020] like Figure 3 As shown, a bridge bearing for bridge engineering includes a connecting component 4 comprising a frame plate 401, a first fastener 402, a sliding plate 403, a second fastener 404, and a groove 405. The frame plate 401 has first fasteners 402 at both ends, a sliding plate 403 at one end of the frame plate 401, a second fastener 404 at one bottom end of the sliding plate 403, and a groove 405 at the other bottom end of the sliding plate 403. The frame plate 401 is arc-shaped and forms a threaded structure with the top frame 2 via the first fasteners 402. The arc-shaped frame plate 401 is installed on the side ring of the bridge bearing via the first fasteners 402 and the second fasteners 404, thus covering the gap between the upper and lower side rings. The second side ring 202 acts as a shield, protecting the support from external dust, insects, and birds, thus effectively protecting the bridge support. The frame plate 401 and the sliding plate 403 are threadedly connected, and the sliding plate 403 and the sliding groove 405 are slidably connected. The sliding plate 403 is used to cooperate with the sliding groove 405, which is located on the side of the first side ring 102. When the bottom end of the frame plate 401 is threadedly connected to the sliding plate 403, the second side ring 202 will slide along the track of the sliding groove 405 through the frame plate 401 and the sliding plate 403 when the support is under force. At the same time, there is a certain gap between the bottom of the sliding groove 405 and the sliding plate 403, so as to avoid excessive internal force and deformation due to constraint, which could lead to structural damage.

[0021] Working principle: First, the support cylinder 301 is set on both sides inside the support, and the support cylinder 301 and the connecting rod 302 are sleeved together. At the same time, the top is fitted by the buffer spring 303, so that the buffer seat 104 in the middle of the bridge support reduces the force on the buffer seat 104 when it is under force.

[0022] The two work together to increase the seismic resistance of bridge bearings;

[0023] The frame plate 401 is arc-shaped and is installed on the side ring of the bridge bearing by the first fastener 402 and the second fastener 404. The frame plate 401 covers the gap between the upper and lower side rings and protects the bearing.

[0024] The baffle 401 is fixed at both ends with fasteners, which makes it convenient for staff to disassemble and replace the baffle 401 in the future.

[0025] Since the bottom end of the frame plate 401 is threadedly connected to the slide plate 403, when the support is under force, the second side ring 202 will slide along the track of the slide groove 405 through the frame plate 401 and the slide plate 403. At the same time, there is a certain gap between the bottom of the slide groove 405 and the slide plate 403 to avoid excessive internal force and deformation due to constraint, which could lead to structural damage.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
