Description

Technical Field

[0001] The present invention relates to the technical field of bridge supports, and in particular to a support for a bridge. Background Art

[0002] A bridge generally refers to a structure built over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. A bridge is generally composed of a superstructure, a substructure, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; supports are force-transmitting devices installed at the supporting locations between the span structure and the piers or abutments. Bridge supports are important structural components connecting the superstructure and substructure of a bridge. They can reliably transmit the reaction force and deformation (displacement and rotation) of the superstructure to the substructure. They are devices installed on piers and support the superstructure from the top surface. Their function is to fix the superstructure to the piers, withstand various forces acting on the superstructure, and reliably transmit them to the piers.

[0003] Bridge bearings are divided into many types according to different usage requirements. Plate rubber bearings are one of them. Rubber bearings are ordinary rubber bearing products made of multiple layers of steel plates and multiple layers of rubber sheets vulcanized and bonded. This product has sufficient vertical stiffness and can reliably transmit the reaction force of the upper structure of the bearing to the pier. The bearing has good elasticity to cope with the rotation of the beam end of the bridge. However, this type of rubber bearing still has certain shortcomings in actual use. Since it is made of steel plates and multiple layers of rubber sheets vulcanized and bonded, the connection between the steel plates and multiple layers of rubber sheets is very firm. When the rubber sheet needs to be replaced due to aging or other reasons, the rubber column and steel plate are usually replaced as a whole. This will be inconvenient to replace the rubber column and will increase the replacement cost. Therefore, a bridge bearing is needed to solve the above problems. Summary of the Invention

[0036] In an embodiment of the present invention, a bridge bearing 100 includes a base plate assembly 110 and a replacement assembly 130, which are spatially symmetrically distributed. Base plate assembly 110 includes a first fixing steel plate 111 and a second fixing steel plate 112, one of which is used to connect to a bridge pier and the other to connect to the bridge. Replacement assembly 130 is slidably connected to first and second fixing steel plates 111, 112, and multiple lifting and limiting mechanisms 134 are used to limit the position of first assembly plate 132 and first fixing plate 111, and second assembly plate 133 and second fixing plate 112.

[0037] In an embodiment of the present invention, bridge bearing 100 includes a positioning assembly 120, which includes a plurality of positioning posts 121. Positioning posts 121 are spatially symmetrically distributed on a side of first and second fixing steel plates 111, 112 that is away from spacer mounting locations 113. Positioning posts 121 are used to position first and second fixing steel plates 111, 112 when they are connected to a pier or bridge, thereby improving installation efficiency and reliability.

[0038] The present invention provides a bridge support 100 including a base plate assembly 110, a positioning assembly 120 and a replacement assembly 130. The base plate assembly 110 includes a first fixed steel plate 111 and a second fixed steel plate 112. The first fixed steel plate 111 and the second fixed steel plate 112 are spaced apart to form a spacing installation position 113. One of the first fixed steel plate 111 and the second fixed steel plate 112 is used to connect to the bridge pier, and the other is used to connect to the bridge; the positioning assembly 120 includes a plurality of positioning columns 121, and the plurality of positioning columns 121 are respectively arranged on the side of the first fixed steel plate 111 and the second fixed steel plate 112 away from the spacing installation position 113; the replacement assembly 130 can be slidably arranged on The spaced mounting position 113, the replacement component 130 includes a rubber column 131, a first assembly plate 132, a second assembly plate 133 and a plurality of lifting and limiting mechanisms 134, the first assembly plate 132 and the second assembly plate 133 are relatively arranged at the two ends of the rubber column 131, the first assembly plate 132 abuts against the first fixed steel plate 111, the second assembly plate 133 abuts against the second fixed steel plate 112, and a plurality of lifting and limiting mechanisms 134 are relatively fixed on the first assembly plate 132 and the second assembly plate 133 in pairs, and the plurality of lifting and limiting mechanisms 134 are used to limit the first assembly plate 132 and the first fixed steel plate 111 and the second assembly plate 133 and the second fixed steel plate 112. This application uses the coordination setting between the positioning component 120, the base plate component 110 and the replacement component 130. When the rubber column 131 needs to be replaced, it is first necessary to use several jacks to support the first fixed steel plate 111 and the second fixed steel plate 112, and then release the limit between the first assembly plate 132 and the first fixed steel plate 111 and the second assembly plate 133 and the second fixed steel plate 112 through the action of the lifting limit mechanism 134. Then, the rubber column 131 is pulled to drive the first assembly plate 132 and the second assembly plate 133 to slide relative to the first fixed steel plate 111 and the second fixed steel plate 112. In this way, the rubber column 131 can be pulled out and then replaced. The base plate component 110 does not need to be disassembled during replacement, which realizes the convenience of local replacement of the rubber support while reducing the maintenance cost of the rubber support.

[0039] Reference Figures 1 to 5The first fixed steel plate 111 is provided with a plurality of positioning holes 111a, and the first assembly plate 132 is provided with a lifting opening 132a on the side facing the rubber column 131. The lifting and limiting mechanism 134 includes a lifting plate 134a, a threaded column 134d and a support frame 134e. The support frame 134e is provided with a threaded through hole 134f, and the threaded column 134d passes through the threaded through hole 134f and is connected to the lifting plate 134a. The threaded column 134d is used to drive the lifting plate to rise and fall along the depth direction of the lifting opening 132a. The bottom of the lifting plate 134a is provided with a plurality of positioning protrusions 134b, and the plurality of positioning protrusions 134b are movably matched with the positioning holes 111a to fix and limit the first fixed steel plate 111 and the first assembly plate 132. It is understood that when the rubber column 131 needs to be replaced, it is first necessary to use several jacks to support the first fixed steel plate 111 and the second fixed steel plate 112. Then, the threaded column 134d is rotated, and the lifting plate 134a is driven upward by the threaded transmission until the positioning protrusion 134b moves out of the positioning hole 111a. In this way, the positioning protrusion 134b can prevent the replacement assembly 130 from sliding with the base assembly 110. At the same time, it can also facilitate the rapid replacement of the replacement assembly 130 with the base assembly 110.

[0040] Reference Figure 2 and Figure 5 The lifting and limiting mechanism 134 also includes a limiting bearing 134i. A bearing hole 134c is defined on the side of the lifting plate 134a near the support frame 134e. The limiting bearing 134i is embedded in the bearing hole 134c. One end of a threaded column 134d is connected to the limiting bearing 134i. In this way, the threaded column 134d, through threaded engagement, drives the lifting plate 134a to move up and down along the depth direction of the lifting opening 132a.

[0041] Reference Figure 2 and Figure 5 The lifting and limiting mechanism 134 also includes a plurality of limiting posts 134j. Limiting holes 134h are provided on both ends of the support frame 134e, parallel to the threaded through-holes 134f. The limiting posts 134j pass through the limiting holes 134h and connect to the lifting plate 134a. In this embodiment, the limiting posts 134j cooperate with the limiting holes 134h to limit and guide the lifting direction of the lifting plate 134a, thereby improving the reliability of the movement of the lifting and limiting mechanism 134.

[0042] Of course, in other embodiments, the first fixed steel plate 111 may be provided with a plurality of positioning holes 111a, the lifting and limiting mechanism 134 may include a lifting plate 134a and a threaded post 134d, the lifting plate 134a having a threaded through-hole, the first assembly plate 132 having a lifting groove on the side facing the rubber post 131, the lifting plate 134a being liftable within the lifting groove through the threaded engagement between the threaded post 134d and the threaded through-hole, the lifting plate 134a being provided with a plurality of positioning protrusions 134b on the side facing the bottom of the lifting groove that engage with the positioning holes 111a, and the bottom of the lifting groove having a plurality of through-holes for the positioning protrusions 134b to pass through and engage with the positioning holes 111a for fixation. In this way, the positioning protrusions 134b only pass through the through-holes to engage with the positioning holes 111a, while the support frame 134e is reduced in size, and the threaded post 134d engages with the groove bottom to enable the threaded post 134d to drive the lifting plate 134a to move upward and downward. Improve the cooperation of the lifting and limiting mechanism 134.

[0043] Reference Figure 1 and Figure 4 The bridge support 100 further includes a clamping plate assembly 140, which includes a first clamping plate 141 and a second clamping plate 142. The first clamping plate 141 and the second clamping plate 142 are spaced apart and arranged on the first fixed steel plate 111 or the second fixed steel plate 112, and the arrangement direction of the first clamping plate 141 and the second clamping plate 142 is perpendicular to the arrangement direction of the positioning holes 111a. A sliding groove 143 is formed between the first clamping plate 141 and the second clamping plate 142. The sliding groove 143 cooperates with the outer periphery of the first assembly plate 132 or the second assembly plate 133 to limit the sliding direction of the first assembly plate 132. It can be understood that the present application limits the replacement assembly 130 in a direction perpendicular to the arrangement direction of the positioning holes 111a by providing the clamping plate assembly 140, thereby improving the multi-degree-of-freedom limiting capability between the first assembly plate 132 and the first fixed steel plate 111 and the second assembly plate 133 and the second fixed steel plate 112. In the present application, the first clamping plate 141 and the second clamping plate 142 are roughly arranged in an "L" shape or a "T" shape, etc. The first clamping plate 141 and the second clamping plate 142 are symmetrically arranged on one side of the first fixed steel plate 111 or the second fixed steel plate 112 close to the gap mounting position to form a sliding clamping groove 143, so that the first assembly plate 132 and the second assembly plate 133 can be slidably engaged in the sliding clamping groove 143, wherein the first clamping plate 141 and the second clamping plate 142 cooperate with the outer periphery of the first assembly plate 132 or the second assembly plate 133 to limit the sliding direction of the first assembly plate 132.

[0044] Furthermore, first and second mating portions 132b, 132c are provided on the outer peripheries of opposite ends of the first and second assembly plates 132, 133. The first and second mating portions 132b, 132c are provided in the form of bosses, and the first and second mating portions 132b, 132c are slidably engaged with the sliding slots 143. Thus, by providing bosses on the first and second mating portions 132b, 132c at opposite ends of the first and second assembly plates 132, 133, and by utilizing the bosses to engage with the sliding slots 143, the sliding directions of the first and second assembly plates 132, 133 are limited.

[0045] Reference Figure 1 and Figure 4 In some embodiments, the card assembly 140 further includes a fastener 144. The first mating portion 132b and the second mating portion 132c are provided with a plurality of fixing holes 132d in a linear array. The first card 141 and the second card 142 are provided with a plurality of holes 141a corresponding to the fixing holes 132d. The fastener 144 passes through the mating holes 141a and the fixing holes 132d to secure the first mating portion 132b to the first card 141 or the second mating portion 132c and the second card 142. In this manner, when the replacement assembly 130 slides to a predetermined position, the fastener 144 can be inserted through the mating holes 141a and the fixing holes 132d to lock the first assembly plate 132 and the second assembly plate 133 in the sliding direction. During disassembly, use tools to remove the fastener 144, and then pull the rubber column 131 to drive the first assembly plate 132 and the second assembly plate 133 to slide relative to the first fixed steel plate 111 and the second fixed steel plate 112. The rubber column 131 can be pulled out and then replaced. The steel plate does not need to be disassembled during replacement, which is not only convenient and quick to replace, but also reduces the cost of replacement.

[0046] Reference Figure 1 and Figure 4In one embodiment, a plurality of mounting holes 111b are provided on the outer peripheries of the opposite ends of the first fixing steel plate 111 and the second fixing steel plate 112. The plurality of mounting holes 111b are arranged in a linear array, and the array direction of the mounting holes 111b is perpendicular to the array direction of the positioning holes 111a. It can be understood that the present application provides mounting holes 111b on the first fixing steel plate 111 and the second fixing steel plate 112 for assembling the first fixing steel plate 111 and the second fixing steel plate 112 with the piers and the bridge. Specifically, when the bridge support 100 needs to be used, the first fixing steel plate 111 and the second fixing steel plate 112 first need to be placed in the use position, and assembled with the piers and the bridge deck through the positioning columns 121. Then, anchor bolts are used to pass through the mounting holes 111b to fix them to the bridge or piers to complete the installation of the bridge support 100.

[0047] In one embodiment, the support frame 134e is integrally formed with the first assembly plate 132 or the second assembly plate 133. In this way, the support plate is integrally formed with the first assembly plate 132 or the second assembly plate 133, thereby reducing stress concentration on the support plate and improving the support capacity of the support plate.

[0048] The working principle of the bridge bearing 100 is as follows:

[0049] 1. When the bridge support 100 is to be used, the first fixing steel plate 111 and the second fixing steel plate 112 are first placed in the use position and assembled with the bridge pier and the bridge deck through the positioning column 121. Then, anchor bolts are passed through the mounting holes 111b to fix them to the bridge or the bridge pier to complete the installation of the bridge support 100.

[0050] 2. When the rubber column 131 needs to be replaced, first use several jacks to support the first fixed steel plate 111 and the second fixed steel plate 112. Then rotate the threaded column 134d, and the lifting plate 134a can be driven upward by the threaded transmission until the positioning protrusion 134b moves out of the positioning hole 111a.

[0051] 3. Then use tools to remove the fastener 144, and then pull the rubber column 131 to drive the first assembly plate 132 and the second assembly plate 133 to slide relative to the first fixed steel plate 111 and the second fixed steel plate 112 to pull out the rubber column 131, and then the rubber column 131 can be replaced.
