An anti-seismic spherical bearing
Features
An anti-seismic spherical bearing
It can withstand tension, compression and shear (lateral) forces under the action of huge random earthquake forces, as long as the upper and lower structures themselves are not destroyed due to With the existence of this kind of bearing, there will be no catastrophic consequences such as falling beams or falling frames (generally speaking, the bearing is a weak link, and it is easy for beams or falling frames to fall under the action of strong earthquake forces. However, this kind of bearing has high strength and ductility. Because of the structure itself, it is especially suitable for fortification in high-intensity seismic areas and has the ability to withstand seismic intensity
.
Seismic spherical bearing
It can rotate in all directions and can carry load in all directions. It meets the requirements for rapid transmission, rotation and movement of the reaction force generated by various loads on the superstructure (such as dead load, live load, wind and earthquake force, etc.) and ensures that the reaction resultant force is concentrated clearly and reliably.
Seismic spherical bearing
With Compared with other bearings (such as plate rubber bearings and basin-type rubber bearings), the isostatic stiffness is large. Under the action of the huge self-weight and inertial force of trains and large automobiles, the bearing only produces minimal deformation, which can reliably ensure the operation of automobiles, trains, especially high-speed vehicles. The smoothness.
Anti-seismic spherical bearings
The force-bearing area is large through the spherical surface and the optimized combination of machine materials is used. Therefore, compared with other hinge structure supports (such as swing bearings and roller bearings) The volume and height of the seats are greatly reduced, the weight is light, easy to install, and the cost is lower than steel bearings with the same bearing capacity.

Good durability. No rubber is used to bear pressure. There is no impact of rubber aging on the rotation performance of the bearing.
Sliding anti-seismic spherical bearings are particularly suitable. It is more suitable for projects such as wide bridges, curved bridges, cable-stayed bridges, ramp bridges, and large-span spatial structures, especially in areas with high seismic intensity.
The sliding anti-seismic spherical bearing has a tensile structure that can reduce the number of bridge ends. Ballast weight block.
Seismic-resistant spherical steel bearings have developed a series of parametric products that can meet various technical requirements of different users and can be designed according to user requirements

Things that should be paid attention to when selecting
When selecting a support, you should pay attention to the size of the bearing capacity, the size of the vertical pulling force, the size of the horizontal force, and pay attention to the displacement, rotation angle and horizontal elastic stiffness.
When selecting the support, you should pay attention to Pay attention to the type of the support, which is two-way movable type and one-way movable type fixed type.
Displacement and stiffness are given in the constraining directions of the shock-absorbing bearing for the needs of engineering shock absorption.

Installation
The connection form of the installation plan of the support should be specifically negotiated with the structural designer to ensure reliable connection and function of the upper and lower structures and the support.
The number of the lower reinforced concrete column must not be Below grade.
The internal reinforcement of the column should refer to the research and analysis results during the design of this support, that is, within the height range from the top of the column along the column axis to the column foot (the horizontal stirrup section increases as the column section width increases The increase in configuration is determined based on the bearing capacity analysis results.
The movable support sets an offset value between the upper support plate and the sliding plate according to design needs.
If welding is used to connect the support and the embedded steel plate, cooling measures or intermittent welding of opposite sides should be taken to prevent the steel parts of the support from overheating and damaging the PTFE plate rubber sealing ring and silicone grease.
Before installation, the elevation and levelness of the substructure should meet the design requirements. The height difference between the four corners of the support shall not be greater than mm.
The center line of the support should coincide with the center line of the main beam and the installation line of the lower structure.
After the support is installed in place, the base plate and the embedded steel plate are welded to meet the design requirements. The temporary connections should be removed immediately after the beam construction is completed.
When installing the support, the connection between the upper support plate and the lower support plate must be installed. After the support is installed, remove it and install the dust cover immediately (the dust cover is a rubber plate and is constructed on site. The unit is responsible for installation).
