Anti-seismic spherical steel bearing
Yes Our company specializes in creating high-quality products of first-class quality. The anti-seismic spherical steel bearing
is made of high-quality materials by our company. Manufacturer's anti-seismic spherical steel bearing
Pricing promotion.
Seismic spherical steel bearing
Mainly composed of upper seat plate, lower seat plate, spherical steel lining plate, displacement box, elastic shock absorber, stainless steel plate and polytetrafluoroethylene plate. It uses less steel and is small in size. The finished product is relatively low. It has advantages that other types of bearings such as universal rotation and load-bearing cannot match. It also adopts a special structure that is resistant to tension and shear, and has the ability to withstand earthquake intensity. ability. The advent of this product has created extremely favorable conditions for reducing project costs, improving overall project quality and earthquake prevention and disaster reduction capabilities. It has great promotion and application value in the field of large-span space structure construction that is booming at home and abroad today.
Seismic spherical steel bearings
According to the structural form, it can be divided into longitudinal movable bearings, multi-directional movable bearings and fixed bearings.

Features
The material of the bearing, stainless steel plate, polytetrafluoroethylene slide plate, rubber sealing ring, etc. are all implemented in accordance with the standards. The elastic shock absorbing parts are based on automobile leaf springs. Technical conditions are implemented. Cast steel is implemented according to standards. , The anti-seismic spherical steel bearing can rotate in all directions and load in all directions, and can well meet the transmission, rotation and movement of the reaction force generated by various loads on the superstructure (such as dead load, live load, wind, earthquake force, etc.) requirements to ensure that the combined reaction force is concentrated, clear, safe and reliable.
, Anti-seismic spherical steel bearings must 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 damaged, such bearings will not occur Disastrous consequences such as falling beams and falling frames (generally speaking, the support is a weak link. Under the action of strong earthquake forces, falling beams and falling frames are very easy to occur, and the strength and ductility of such supports are higher than those of the structure itself. It is especially suitable for fortification in high-intensity earthquake areas and has the ability to withstand earthquake intensity levels.
Compared with other bearings (such as plate rubber bearings, pot-type rubber bearings, etc.), seismic-resistant spherical steel bearings The static stiffness of the anti-seismic bearing is large. Under the action of huge self-weight and inertial force, the bearing only produces minimal deformation, which can reliably guarantee the building.

, The anti-seismic spherical steel bearing passes through the spherical surface Force transmission, large force-bearing area, and an optimized combination of several materials are used. Therefore, compared with other hinge structure supports (swing supports and roller supports, their volume and height are greatly reduced, light weight, easy to install, and Compared with steel bearings with the same bearing capacity, the cost is lower.
, Anti-seismic spherical steel bearings have a wide applicable temperature range (~+℃) and good durability. Rubber is not used for pressure bearing, and there is no impact of rubber aging on the rotation performance of the bearings. Impact.
, Anti-seismic spherical steel bearings are especially suitable for large-span space structures, long-span bridges, wide bridges, curved bridges, cable-stayed bridges, ramp bridges, especially in areas with high earthquake intensity, and other It is difficult for other types of bearings to meet the requirements.
, Anti-seismic spherical steel bearings have a tensile structure, which can reduce the weight of the bridge end.
, Parametric and serialization of anti-seismic spherical steel bearings have been developed The product can meet various technical requirements of different users, and can be designed and processed according to user requirements.
