is that the rubber block is placed in a sealed steel basin. When the force is applied in three directions, the reaction force generated can bear the vertical load of the bridge. At the same time, the use of rubber It is elastic and meets the rotation of the beam end. Through the free sliding of the stainless steel plate and the PTFE plate welded to the upper seat plate, the horizontal displacement of the bridge superstructure is realized. This series of products has reasonable structure, large load-bearing capacity, small deformation, large horizontal displacement, sensitive rolling, and good buffering function. It is the best bearing for building continuous bridges. The basin-type rubber bearing has the advantages of light weight, compact structure, simple structure, low construction height, convenient processing and manufacturing, saving steel, and reducing the cost. It is an ideal bearing suitable for use in large collapsed bridges.
>1. Pot-type rubber bearings
Classification
> Pot-type rubber bearings
Based on the scale of use, they can be divided into three major categories: highway bridge pot-type rubber bearings
, Railway bridge pot-type rubber bearings
and derivatives of pot-type rubber bearings
. Commonly used road pot-type rubber bearings
models include pot-type rubber rubber bearings and (II) pot-type rubber rubber bearings (based on), pot-type rubber bearings
and other series. Commonly used railway basin rubber bearings
include railway basin rubber bearings
, standard railway basin rubber bearings
, and special railway bridge bearings. There are many derivatives of pot-type rubber bearings
, such as pot-type rubber rubber bearings, series of pot-type rubber bearings
, elastic shock-absorbing spherical steel bearings, and self-adjusting pot-type rubber bearings

>Each type can be divided into three types: fixed, one-way movement and two-way movement according to the displacement mode.
> 2. Basin-type rubber bearing
Installation
> Install the anchor posts at the four corners of the base plate of the bearing.
>. Pour the support pier, leaving a certain height at the top, which is larger than the anchor column of the support
>. Lift the support above the padding stone, and check the plane orientation and height.
>, pour the pad stone concrete
>, install an anchor column on the upper part of the support
>, install the cast-in-place beam formwork, and tie the cast-in-place beam steel bars
>, pour the beam body Concrete
>Remove the temporary connection on both sides of the support.

Use a total station to release the center line of the cover beam and the center line of the bridge, and then draw the support edge line, beam end and beam side edge line on the pad, as well as the center position of the support of the girder, and review the horizontal flatness of the support. There are two types of rubber bearings: ordinary rubber bearings and PTFE sliding plate bearings. When installed, the rubber bearings must be in close contact with the upper and lower structures without any gaps.
