Anti-seismic spherical steel bearings for grid frames
Leading sales in the country The anti-seismic spherical steel bearings for the grid recommended by high-quality manufacturers are certified by our company through a national third party.
1. The anti-seismic spherical steel bearings of the grid frame can withstand vertical loads, resist vertical tension and horizontal forces, and can adapt to radial and circumferential displacement requirements, and the bearings do not use rubber board, there is no problem of rubber board aging. The grid shock-absorbing steel ball bearing can withstand vertical loads, has resistance to vertical tension and horizontal force, can adapt to radial and circumferential displacement requirements, and has good shock-absorbing performance, and the bearing does not use rubber plates. There is no problem of rubber sheet aging.
2. Advantages of grid anti-seismic spherical steel bearings
This kind of bearing adopts surface contact, with large contact surface, low pressure and uniform force transmission, so it is small in size and requires less steel. Small. , 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. , 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 bearings will produce pull-out forces. Other types of supports cannot withstand excessive pull-out forces and shear forces. , Can be rotated in all directions. , the interior is a spherical dumpling, so it can rotate in all directions. The size of the corner can be designed according to engineering requirements, and the rotation of the support can generally be ((radian)). This function is most suitable for wide bridges, ramp bridges (inclined bridges) and spatial structures

4. Main technical performance of grid earthquake-resistant spherical steel bearing
, can withstand vertical load
, It has the performance of resisting vertical tensile force, ensuring that the upper and lower structures will not be disconnected during vertical earthquakes
, It has the performance of resisting horizontal force, ensuring that the beam will not fall during horizontal earthquakes
, It can be adapted to radial and circumferential directions Displacement requirements
, can adapt to angle requirements in any direction
, the bearing has good shock absorption performance
, the overall performance of the bearing is good
, the bearing transmits force through the spherical surface , there is no force necking phenomenon, and the reaction force acting on the upper and lower structures is relatively uniform
