& Rubber Bearing Bearing refers to a supporting component used to support the weight of a container or equipment and fix it in a certain position. It also withstands vibration and seismic loads during operation. Rubber bearings are closely combined with rubber and thin steel plates to support the weight of the bridge.
Rubber bearing type classification Plate rubber bearing is a bridge bearing product made of multiple layers of natural rubber and at least two layers of thin steel plates of the same thickness inlaid, bonded and vulcanized. This type of rubber bearing has sufficient vertical stiffness to withstand vertical loads and can reliably transmit the pressure of the upper structure to the pier. It has good elasticity to adapt to the rotation of the beam end and large shear deformation to satisfy the upper structure. Horizontal displacement of structure
Plate bearings are divided according to shape: rectangular and circular products.
According to whether it can provide horizontal displacement, it is divided into: polytetrafluoroethylene slide bearing and ordinary rubber bearing.
Rectangular (circular) plate
Performance: This product is made of multi-layer rubber sheets and thin steel plates inlaid and bonded, vulcanized and pressed under a certain pressure, a certain temperature and a certain period of time. It has sufficient vertical stiffness to bear vertical loads, can reliably transmit the reaction force of the upper structure of the beam plate to the pier, has good elasticity to adapt to the rotation of the beam end, and has large shear deformation to satisfy the upper beam. Horizontal displacement of the body structure. Features: This product has been widely used in bridge construction, hydropower projects, and house earthquake-resistant facilities. Compared with the original steel bearings, it has the advantages of simple structure, convenient installation, saving steel, low price, simple maintenance, and easy replacement. The product has a low building height, which is beneficial to bridge design and cost reduction. It has a good seismic isolation effect and can reduce the impact of live loads and seismic forces on the building.
PTFE skateboard type
Referred to as PTFE skateboard type bridge bearing, this product is made by bonding a thick layer of PTFE plate to an ordinary plate rubber bearing. In addition to the vertical stiffness and elastic deformation of ordinary plate rubber bearings, which can withstand vertical loads and adapt to beam end rotation, the low friction coefficient (&&.) between PTFE and the stainless steel plate at the bottom of the beam can make the upper structure of the bridge more stable. Horizontal displacement is not limited. Long-span bridges with a span of &meter, simply supported beam continuous plate bridges and multi-span continuous beam bridges can be used as movable supports. Continuous beam push, profile beam lateral movement and large equipment sliding can be used as sliders. use. Rubber bearing material classification:: Neoprene: Applicable temperature +℃∽℃b: Natural rubber: Applicable temperature +℃∽℃
The structural principle of the basin-type rubber bearing is a rubber block placed in a sealed steel basin , in the case of three-way stress, the reaction force generated bears the vertical load of the bridge. At the same time, the elasticity of the rubber is used to meet the rotation of the beam end, and the free movement of the stainless steel plate and polytetrafluoroethylene welded to the upper seat plate is Slip, completing the horizontal displacement of the bridge superstructure. This series of products has reasonable structure, large load-bearing capacity, small deformation, large horizontal displacement, flexible rotation, and good buffering performance. It is the best bearing for building continuous bridges.
Basin-type rubber bearing< br/> It also has the advantages of light weight, compact structure, simple structure, low building height, convenient processing and manufacturing, saving steel, and reducing cost. It is an ideal bearing suitable for use in large collapsed bridges. Commonly used are, (Ⅱ), three categories. The current bearing capacity of this series of bearings is level 1, bearing capacity., which can meet the needs of large-scale bridge construction.
In the standard series, the horizontal bearing capacity of the fixed bearing in all directions and the non-slip direction of the one-way movable bearing is not less than % of the vertical bearing capacity of the bearing. The horizontal bearing capacity of the earthquake-resistant bearing shall not be less than % of the vertical bearing capacity of the bearing. The rotation angle of the bearing is not less than .r.
After adding silicone grease lubrication, the design friction coefficient of the normal temperature movable bearing shall be the minimum. After adding silicone grease lubrication, the design friction coefficient of the cold-resistant movable bearing shall be the minimum. .
Rubber bearing bearing classification
Pot-type rubber bearings can be divided into three categories according to their application scope: highway bridge pot-type rubber bearings, railway bridge pot-type rubber bearings and pot-type rubber bearings derivatives. Commonly used highway pot-type rubber bearing 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 pot rubber bearings include railway pot rubber bearings, standard railway pot rubber bearings, and special railway bridge bearings. There are many types of derivatives of pot-type rubber bearings, such as pot-type rubber bearings, series of pot-type rubber bearings, elastic shock-absorbing spherical steel bearings, self-adjusting pot-type rubber bearings, etc.
Each type can be divided into three types according to the displacement form: fixed, one-way movement and two-way movement.
, Installation, install the anchor posts at the four corners of the base plate of the support. . Pour the support pier, leaving a height at the top that is larger than the anchor column of the support. Lift the support above the padding stone, correct the plane position and height, pour padding concrete, and install the upper part of the bearing. anchor columns, install the cast-in-place beam formwork, tie the cast-in-place beam steel bars, pour the beam body concrete, and remove the temporary connections on both sides of the support.
Ball-type bearings are characterized by reliable force transmission and flexible rotation. They not only have the characteristics of large load-bearing capacity and large seat movement of basin-type rubber bearings, but also can better adapt to the needs of large turning angles, unlike ordinary rubber bearings. The basin-type bearing has the following advantages:
The spherical rubber bearing transmits force through the spherical surface, and there will be no force necking phenomenon. The reaction force acting on the concrete is relatively uniform. The spherical rubber bearing is concentrated through the spherical surface. The sliding process of the fluoroethylene plate realizes the rotation process of the support. The power torque is small, and the rotation torque is only related to the spherical radius of the support and the friction coefficient of the PTFE plate, and has nothing to do with the size of the support angle. It is especially suitable for large rotation angles. requirements, the design angle can reach .r., the spherical bearing has consistent rotation performance in all directions, and is suitable for wide bridges and curved bridges. This bearing product does not require rubber to bear pressure, and there is no impact of rubber aging on the rotation performance of the bearing. Especially suitable for low temperature areas.
