Grid frame anti-seismic spherical steel bearings
Advantages:
This kind of bearing adopts surface contact, with large contact surface, low pressure and uniform force transmission, so it is small in size and uses a small amount of steel.
, small in size and low in height, its mechanical calculation diagram is consistent with the overall calculation diagram, and will not cause or reduce the error between the mechanical calculation model and the actual structure.
3. It can be universally loaded, that is, it can withstand pressure, pullout force, and shear force in any direction. The size of the force can be designed according to requirements. The general series products are ~. (In continuous beam bridges, curved bridges, the corners of large grids, and temporary loads generated during construction, the supports will produce pull-out forces. Other types of supports cannot withstand excessive pull-out forces and shear forces.
, It can rotate in all directions. The inside is a spherical dumpling, so it can rotate in all directions. The size of the rotation angle can be designed according to the engineering requirements. The rotation of the support can generally be (.~.) (radian). This function is most suitable for wide bridges and ramps. Bridge (inclined bridge) and space structure.

Grid frame anti-seismic spherical steel bearings
Features
, Anti-seismic spherical steel bearings can be universal Rotation and universal bearing can well meet the transmission, rotation and movement requirements of the reaction force generated by various loads on the superstructure (such as dead load, live load, wind, earthquake force, etc.) and ensure that the reaction force is concentrated. Clear and reliable.
The seismic spherical steel bearing 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 damaged, due to the existence of this kind of bearing There will be no catastrophic consequences such as falling beams or falling frames (generally speaking, the support is a weak link. Under the action of strong earthquake forces, falling beams or falling frames are very easy to occur, and this type of support has high strength and ductility. (to the structure itself), so it is particularly suitable for fortification in high-intensity earthquake areas and has the ability to withstand earthquake intensity.
3. Compared with other bearings (such as plate rubber bearings, basin-type rubber bearings, etc.) rubber bearings, etc.), with high static stiffness. Under the action of the huge weight and inertial force of trains and large automobiles, the bearings only produce minimal deformation, which can reliably ensure the smooth operation of automobiles, trains, especially high-speed vehicles.< br/>, The anti-seismic spherical steel bearing transmits force through a spherical surface, has a large force-bearing area, and adopts an optimized combination of machine materials. Therefore, compared with other hinge structure bearings (such as swing bearings, roller bearings, etc.), Its volume and height are greatly reduced, it is light in weight, easy to install, and its cost is lower than steel bearings with the same bearing capacity.
The applicable temperature range of earthquake-resistant spherical steel bearings is wide (-℃ ~ ℃). It has good durability and does not use rubber to bear pressure. There is no impact of rubber aging on the rotation performance of the bearing.
The anti-seismic spherical steel bearing is especially suitable for wide bridges, curved bridges, cable-stayed bridges, ramp bridges, and large-span spaces. Structural and other projects, especially in areas with high seismic intensity, are more suitable.
,Seismic-resistant spherical steel bearings have a tensile structure, which can reduce the weight of the bridge end.
,Seismic-resistant spherical steel bearings have been developed Parameterized and serialized products can meet various technical requirements of different users and can be designed according to user requirements
