< Advantages of 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 a small amount of steel.
It is small in size and low in height, and its mechanical calculation diagram is consistent with the overall calculation diagram, which will not cause or reduce the error between the mechanical calculation model and the actual structure.
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.)
, can rotate in all directions, and has a spherical hinge inside, 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 (.~.) (radians). This feature is best suited for wide bridges, ramp bridges (inclined bridges) and spatial structures.
Overall performance indicators
, Vertical pressure bearing: ~
, Vertical pull-out force: ~
Horizontal shear force: ~
The above three types of forces can be freely combined and selected according to the needs of the owner and the project.
, Design angle: .~. (radians, equivalent to .~3.)
, Displacement amount of movable spherical support: (~), if there are special needs, it can be designed as needed.
, Friction control coefficient.3 (normal temperature -~)
Installation and maintenance.
When using this series of , the concrete grade of the bridge beam and pier support parts shall not be less than 3. In special circumstances, the consent of the design unit is required.
. Before the < anti-seismic spherical steel bearing
leaves the factory, our Jingtong Engineering Rubber Co., Ltd. has leveled the bearing and tightened the connecting screw to prevent the bearing from rotating and tilting during the installation process. complex.
, Before installation, you can unpack and check the packing list, including a copy of the raw material inspection report, the series spherical bearing product certificate and the bearing installation and maintenance details. After unpacking, the construction unit shall not loosen the connecting bolts at will, and shall not disassemble the supports at will.
, It is connected with the beam body and pier by embedded bolts. If necessary, it can also be welded with embedded steel plate. However, when the series spherical bearing is welded with embedded steel plate , to prevent the steel body of the support from overheating to avoid burning the silicone grease and PTFE plate and causing the support itself to deform.
