Description

Technical Field

[0001] The utility model relates to the technical field of bridge supports, and more specifically, to a basin-type bridge rubber support. Background Art

[0002] The pot-type bridge rubber bearing is a new type of bridge bearing composed of steel components and rubber. Compared with other similar pot-type bearings and cast steel roller bearings, it has the advantages of large bearing capacity, large horizontal displacement and flexible rotation.

[0003] At present, the existing basin-type rubber steel bearings on the market use the deformation of the rubber block in the steel basin to achieve rotation; and use the plane sliding between the polytetrafluoroethylene plate and the stainless steel plate to adapt to the requirements of beam deformation and displacement. The steel basin wall not only bears the horizontal force generated by the load, but also the rubber plate will generate lateral pressure under the vertical pressure, and the steel basin wall and the steel basin plate jointly bear the vertical pressure.

[0004] Therefore, for pot-type bridge rubber bearings, the sizes of stainless steel plates and rubber plates are particularly important. The right size can evenly share the pressure, which not only brings good bearing capacity and rotational force to the device, but also further improves the service life of the device due to the uniform pressure distribution. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a pot-type bridge rubber bearing with a vertical bearing capacity of up to 6000KN, a horizontal force of up to 15% of the vertical bearing capacity, a rotation angle of 0.02rad, high bearing capacity and stable support.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A basin-type bridge rubber bearing comprises a fixing component, a pressure-bearing component is installed on the top of the fixing component, and a supporting component is arranged at one end of the pressure-bearing component away from the fixing component; the supporting component comprises a top plate, and the width of the top plate in the transverse direction of the bridge is set to b, and the value of b is 770MM; the length of the top plate in the longitudinal direction of the bridge is set to d, and the value of d is 860MM.

[0008] The utility model is further configured as follows: the pressure-bearing component includes a stainless steel plate, a polytetrafluoroethylene plate is arranged at one end of the stainless steel plate away from the supporting component, an intermediate steel plate is installed at the bottom of the polytetrafluoroethylene plate, the transverse dimension of the polytetrafluoroethylene plate is smaller than that of the stainless steel plate, and a rubber plate is installed at one end of the intermediate steel plate close to the fixing component.

[0009] By adopting the above technical solution, the rubber plate has the properties of a fluid under three stress states, which is used to realize the rotation of its upper structure. At the same time, the horizontal displacement of the upper structure is realized by relying on the low friction coefficient between the polytetrafluoroethylene plate on the middle steel plate and the stainless steel plate on the upper seat plate. The bearing capacity of the device is improved by the overall structure of the pressure-bearing component, so that the device is a product that can meet the requirements of large supporting force, large horizontal displacement, and large rotation angle. The design of the pressure-bearing component enables the vertical bearing capacity of the device to reach 6000KN, the horizontal force can reach 15% of the vertical bearing capacity, and the rotation angle can reach 0.02rad.

[0010] The utility model is further configured as follows: a group of support rods are respectively arranged at the four corners of the top plate; the support rods are arranged along the direction of the bridge. The distance between the two groups of support rods in the transverse direction of the bridge is set to c, and the value of c is 600MM; the distance between the two groups of support rods in the direction of the bridge is set to e, and the value of e is 770MM.

[0011] The utility model is further configured as follows: the fixing assembly includes a steel basin, which is arranged at the bottom of the rubber plate; a group of anchor rods are arranged at each of the four corners of the steel basin; wherein the distance between the steel basin and the top plate is set to a, and the value of a is 155MM; the transverse length between the two groups of steel basins is set to i, and the value of i is 680MM; the longitudinal width between the two groups of steel basins is set to g, and the value of g is 680MM.

[0012] The utility model is further configured as follows: a group of anchor rods are respectively arranged at the four corners of the steel basin; the diameter of the anchor rods is set to j, and the value of j is 70MM; the transverse distance between the two groups of anchor rods is set to h, and the value of h is 510MM; the longitudinal distance between the two groups of anchor rods is set to f, and the value of f is 510MM.

[0013] By adopting the above technical solution, a pressure-bearing component is arranged in the recess of the steel basin, and the steel basin provides a stable installation environment for the pressure-bearing component, so that the pressure-bearing effect of the pressure-bearing component is good, thereby improving the pressure-bearing capacity of the device.

[0014] The utility model is further configured as follows: the anchor rod needs to be installed inside a hole filled with epoxy mortar; wherein the length of the anchor rod placed at the bottom of the bridge plate is set to k, and the value of k is 200MM; the inner diameter of the anchor rod installation hole is set to m, and the value of m is 130MM; the depth of the anchor rod installation hole is set to l, and the value of l is 260MM.

[0015] By adopting the above technical solution, the anchor rod is installed in the hole filled with epoxy mortar, so that the device can be stably fixed, avoiding displacement caused by vehicles passing on the bridge, and improving the stability of the device.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. The basin-type bridge rubber bearing has a simple structure and flexible disassembly, which can be flexibly disassembled by disassembling the anchor rod. The pressure-bearing structure of the device includes a stainless steel plate, a polytetrafluoroethylene plate, an intermediate steel plate and a rubber plate, wherein the rubber plate has the properties of a fluid under three stress states, and is used to realize the rotation of its upper structure, and the rotation angle can reach 0.02rad, so that the upper structure can rotate flexibly.

[0018] 2. At the same time, the device relies on the low friction coefficient between the polytetrafluoroethylene plate on the middle steel plate and the stainless steel plate on the upper seat plate to achieve the horizontal displacement of the upper structure, so that the vertical bearing capacity of the device can reach 6000KN, the vertical bearing capacity is high, the horizontal force can reach 15% of the vertical bearing capacity, and the displacement along the bridge is ±150MM.

[0019] 3. Since the vertical bearing capacity of this device can reach 6000KN and the horizontal force can reach 15% of the vertical bearing capacity, compared with the pot-type bridge rubber bearing of the same size, it has a higher bearing capacity and can be applied to larger bridges.
