Description

Technical Field

[0001] The utility model belongs to the technical field of bridge pier supports, in particular to a bridge pier support. Background Art

[0002] Pier supports are important force-transmitting structures of bridges. Their function is to transfer various loads of the superstructure and adapt to the displacements caused by factors such as temperature, shrinkage and creep. There are many types, such as curved steel supports, plate rubber supports, etc.

[0003] The rubber bearings in the existing plate-type rubber bearings are exposed to the outside and unprotected, and are easily eroded by external dust, worn, aged, and easily damaged by direct impacts from foreign objects. They have a short service life and need to be replaced frequently, which is very inconvenient. Summary of the invention

[0004] The utility model aims to solve the above-mentioned technical problems existing in the prior art and to provide a bridge pier support which has novel structure, is stable and reliable, has dustproof and protective functions, and is durable.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A bridge pier support, comprising: a support body, the support body is arranged between a T-beam and a bridge abutment cap beam, the support body is connected to the T-beam through vertical steel bars, and is characterized in that: the support body comprises an upper steel plate, a lower steel plate and a rubber support, the upper steel plate is arranged on the top of the rubber support, the lower steel plate is arranged on the bottom of the rubber support, a dust cover is arranged between the upper steel plate and the lower steel plate, and the dust cover covers the rubber support. The bridge pier support has a novel structure, is stable and reliable, has dustproof and protective functions, and is durable.

[0007] Furthermore, an embedded steel plate is provided between the support body and the T-beam, and the embedded steel plate connects the upper steel plate and the vertical steel bars. The embedded steel plate and the upper steel plate are conveniently connected, thereby improving the installation reliability of the support body.

[0008] Furthermore, transverse steel bars are provided between the vertical steel bars, and the transverse steel bars are connected to the embedded steel plates. The two adjacent vertical steel bars are connected as one and restrain each other, and the structure has high stability. The provision of the transverse steel bars increases the contact area between the vertical steel bars and the embedded steel plates, thereby improving the connection strength between the vertical steel bars and the embedded steel plates.

[0009] Furthermore, the embedded steel plate is provided with positioning grooves corresponding to the transverse reinforcement, so that the transverse reinforcement can be quickly installed on the embedded steel plate, which reduces the difficulty of positioning and improves the installation efficiency.

[0010] Furthermore, the vertical steel bars, the transverse steel bars and the embedded steel plates are fixed by welding, so the connection is reliable and difficult to separate freely.

[0011] Furthermore, the embedded steel plate exceeds the bottom surface of the T-beam by 10-20 mm, which, on the one hand, facilitates the construction of the embedded steel plate, and on the other hand, can eliminate the slope of the bottom of the T-beam, which is conducive to the horizontal setting of the support body.

[0012] Furthermore, the width of the embedded steel plate is greater than the width of the support body, which ensures that there is sufficient contact area between the embedded steel plate and the support body and the T-beam, thereby improving the supporting effect of the support body on the T-beam.

[0013] Furthermore, a pad is provided between the support body and the abutment cap beam, and the lower steel plate is connected to the pad. The setting of the pad can eliminate the height difference between the support body and the abutment cap beam on the one hand, and on the other hand, enable the support body to adapt to the slope of the bottom of the T-beam, which is conducive to the horizontal setting of the support body.

[0014] Furthermore, the width of the pad is greater than the width of the support body, ensuring sufficient contact area between the pad and the support body and the abutment cap beam, thereby improving the supporting effect of the pad on the support body.

[0015] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0016] 1. The dust cover can not only prevent dust from corroding the rubber bearing, but also play a protective role to prevent foreign objects from directly hitting the rubber bearing. The rubber bearing is not easy to wear and crack, which extends the service life of the rubber bearing. The dust cover has a simple structure and strong practicality.

[0017] 2. An embedded steel plate is provided between the support body and the T-beam. The embedded steel plate is conveniently connected to the upper steel plate, which improves the installation reliability of the support body. The embedded steel plate can also eliminate the slope of the bottom of the T-beam, which is conducive to the horizontal setting of the support body.

[0018] 3. Horizontal steel bars are arranged between the vertical steel bars. The horizontal steel bars are connected to the embedded steel plates. The two adjacent vertical steel bars are connected as one and restrain each other. The structural stability is high. The arrangement of the horizontal steel bars increases the contact area between the vertical steel bars and the embedded steel plates, thereby improving the connection strength between the vertical steel bars and the embedded steel plates.

[0019] 4. A pad is provided between the support body and the abutment cap beam. The setting of the pad can eliminate the height difference between the support body and the abutment cap beam on the one hand, and enable the support body to adapt to the slope of the bottom of the T-beam on the other hand, which is conducive to the horizontal setting of the support body.
