Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, in particular to a highway bridge support structure with a pressure relief function. Background Art

[0002] In highway bridge projects, bearings, as key components connecting the bridge superstructure and substructure, not only bear the important task of transferring loads, but also need to have the ability to adapt to the deformation of the bridge under various working conditions to ensure the overall stability and safety of the bridge.

[0003] Some existing bridge bearings are not equipped with a pressure release mechanism when in use, and are unable to disperse and relieve the stress generated when the bridge bearings are subjected to huge pressure.

[0004] For example, the announcement number CN217758322U discloses a bridge bearing that is easy to adjust the height. The bridge bearing of this patent forms an automatic lifting mechanism through the designed electric push rod, connecting plate, connecting rod, fixed cylinder, and roller, which is convenient for precise adjustment of the height between the base under the bridge and the bearing on the bridge, and can make the application range of the bridge bearing wider. Through the sliding plate, sliding block and slide groove, the lifting mechanism can operate more stably during height adjustment.

[0005] While these bridge bearings offer advantages in height adjustment and ease of assembly and disassembly, they still have some shortcomings in terms of pressure bearing and pressure release. These bearings primarily rely on rubber discs No. 1 and No. 2 to provide a certain degree of elasticity and cushioning. However, the elasticity of the rubber discs alone may not be sufficient to fully disperse and relieve the stress generated by the bridge bearings under immense pressure. Over the long-term operation of a bridge, the bearings are subject to continuous pressure. Without an effective pressure release mechanism, this accumulated pressure could adversely affect the bearings and the bridge structure.

[0006] Therefore, it is necessary to invent a highway bridge bearing structure with a pressure relief function to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to provide a highway bridge support structure with a pressure relief function to solve the problems in the above technology.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highway bridge support structure with a pressure relief function, comprising a support base plate, a support top plate and a pressure relief mechanism, wherein the support top plate is arranged directly above the support base plate, and the pressure relief mechanism is arranged between the support top plate and the support base plate, and the pressure relief mechanism comprises a conduction rod, the top of the conduction rod is fixedly connected to a No. 1 fixing plate, the No. 1 fixing plate is installed on the bottom of the support top plate by screws, the bottom of the conduction rod is fixedly connected to a connecting plate, a No. 1 damper is installed at the bottom of the connecting plate, the bottom of the No. 1 damper is fixedly connected to the top of the support base plate, and a No. 2 damper is hingedly provided at both ends of the connecting plate, the two No. 2 dampers are both inclined, and the bottoms of the two No. 2 dampers are both hinged to the top of the support base plate.

[0009] By setting a pressure relief mechanism between the supporting bottom plate and the supporting top plate, the pressure relief mechanism is used to effectively disperse and dissipate the impact force generated by the load, thereby improving the stability and safety of the bridge structure.

[0010] Preferably, the number of the pressure relief mechanisms is set to four, and the four pressure relief mechanisms are evenly distributed between the support top plate and the support bottom plate.

[0011] The number of pressure relief mechanisms is set to four and is evenly distributed, which can share the load more evenly and enhance the stability and bearing capacity of the overall structure.

[0013] The No. 1 limiting sleeve and the No. 2 limiting sleeve arranged between the supporting bottom plate and the supporting top plate provide a stable installation position for the rubber shock-absorbing core, thereby enhancing the integrity and positioning accuracy of the structure.

[0014] Preferably, a rubber shock-absorbing core is provided between the supporting top plate and the supporting bottom plate, the bottom of the rubber shock-absorbing core is sleeved inside the No. 1 limiting sleeve, and the top of the rubber shock-absorbing core is sleeved inside the No. 2 limiting sleeve.

[0015] The setting of the rubber shock-absorbing core enhances the shock-absorbing effect of the support structure, effectively absorbs and disperses impact energy, and protects the bridge structure from damage.

[0016] Preferably, a telescopic guide column is fixedly connected to the top of the support base plate, and the number of the telescopic guide columns is set to four, and the four telescopic guide columns are respectively arranged at the four corners of the top of the support base plate.

[0017] Preferably, a No. 2 fixing plate is fixedly connected to the top of the telescopic guide column, and the No. 2 fixing plate is installed on the bottom of the supporting top plate by screws.

[0018] The setting of the telescopic guide column not only plays a guiding and supporting role, but also limits the displacement range of the supporting top plate, preventing it from being damaged due to excessive deformation, thereby improving the stability and durability of the structure.

[0019] Preferably, the bottom of the supporting base plate and the top of the supporting top plate are both fixedly connected with rubber anti-skid pads, and the surface of the rubber anti-skid pads is provided with anti-skid patterns.

[0020] The surfaces of the supporting bottom plate and the supporting top plate are both equipped with rubber anti-slip pads and have anti-slip textures, which increase the friction between the support structure and the bridge superstructure and foundation structure, improve the anti-slip ability of the support structure, and ensure the stability of the structure under load.

[0021] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0022] By setting up a pressure relief mechanism between the supporting top plate and the supporting bottom plate, four evenly distributed pressure relief mechanisms jointly share the load of the support, so that the support structure is more evenly stressed when bearing the load, thereby improving the stability and bearing capacity of the overall structure. By using the No. 1 damper and No. 2 damper on the pressure relief mechanism to consume energy, the vibration amplitude and frequency of the support structure when impacted can be significantly reduced, thereby protecting the bridge structure from damage.

[0030] The utility model provides Figure 1-4 The highway bridge bearing structure with a pressure relief function shown in the figure includes a supporting base plate 1, a supporting top plate 2 and a pressure relief mechanism 3. The supporting top plate 2 is arranged directly above the supporting base plate 1, and the pressure relief mechanism 3 is arranged between the supporting top plate 2 and the supporting base plate 1. The pressure relief mechanism 3 includes a conduction rod 4, and the top of the conduction rod 4 is fixedly connected to a No. 1 fixing plate 5, and the No. 1 fixing plate 5 is installed on the bottom of the supporting top plate 2 by screws. The bottom of the conduction rod 4 is fixedly connected to a connecting plate 6, and a No. 1 damper 7 is installed at the bottom of the connecting plate 6. The bottom of the No. 1 damper 7 is fixedly connected to the top of the supporting base plate 1, and a No. 2 damper 8 is hingedly provided at both ends of the connecting plate 6. The two No. 2 dampers 8 are both inclined, and the bottoms of the two No. 2 dampers 8 are both hinged to the top of the supporting base plate 1.

[0031] In one aspect of this embodiment, the number of pressure relief mechanisms 3 is set to four, and the four pressure relief mechanisms 3 are evenly distributed between the support top plate 2 and the support bottom plate 1. A No. 1 limiting sleeve 9 is fixedly connected to the middle of the top of the support bottom plate 1, and a No. 2 limiting sleeve 10 is fixedly connected to the middle of the bottom of the support top plate 2. The No. 2 limiting sleeve 10 is arranged just above the No. 1 limiting sleeve 9. A rubber shock-absorbing core 11 is provided between the support top plate 2 and the support bottom plate 1. The bottom of the rubber shock-absorbing core 11 is sleeved inside the No. 1 limiting sleeve 9. The rubber shock-absorbing The top of the core body 11 is sleeved inside the No. 2 limiting sleeve 10, and a telescopic guide column 12 is fixedly connected to the top of the support base plate 1. The number of telescopic guide columns 12 is set to four, and the four telescopic guide columns 12 are respectively arranged at the four corners of the top of the support base plate 1. The top of the telescopic guide column 12 is fixedly connected to the No. 2 fixing plate 13, and the No. 2 fixing plate 13 is installed on the bottom of the support top plate 2 by screws.

[0032] Working principle of this utility model:

[0033] Refer to the instruction manual Figure 1-4 When using the present invention, first, when the highway bridge superstructure is subjected to load, the load is transmitted to the pressure relief mechanism 3 through the support top plate 2. At this time, the rubber shock-absorbing core 11 first plays a preliminary shock-absorbing and buffering role, absorbing part of the impact energy and reducing the impact force directly transmitted to the support bottom plate 1. At the same time, since the four pressure relief mechanisms 3 are evenly distributed between the support top plate 2 and the support bottom plate 1, they can share the load together, thereby improving the stability and bearing capacity of the overall structure.

[0034] As the load further acts, the transmission rod 4 transmits the force to the connecting plate 6, and then dissipates the energy through the No. 1 damper 7 and the No. 2 damper 8. The No. 1 damper 7 is arranged vertically and mainly bears the vertical shock absorption function, consuming energy through the flow or deformation of the damping medium (such as oil or elastomer) inside it. The two inclined No. 2 dampers 8 can share the horizontal force to a certain extent, increase the overall stability of the support structure, and prevent structural instability caused by excessive horizontal force.

[0035] In addition, the provision of the telescopic guide column 12 not only provides additional support and guidance for the support structure, but also can limit the displacement range of the support top plate 2 to a certain extent, preventing it from being damaged due to excessive deformation, while the rubber anti-slip pad 14 increases the friction between the support bottom plate 1 and the foundation structure and between the support top plate 2 and the bridge superstructure, thereby improving the anti-slip ability of the support structure.
