Manufacturer of seismic spherical hinge steel bearing

Features of fixed hinge bearing:
1
The material of the support, such as stainless steel plate, Teflon sliding plate and rubber sealing ring, shall be in accordance with the provisions of jt391-1999 standard,
Cast steel shall comply with GB / t11352-1989 and GB / t14408-1993

2
It can rotate and carry in all directions, and can well meet the transmission, rotation and movement requirements of reaction force generated by various loads of superstructure (such as dead load, live load, wind, seismic force, etc
), so as to ensure that the reaction force is concentrated, clear, safe and reliable

In recent years, due to the deformation, cracking and other component damage of some bridge structures, as well as the occurrence of natural disasters such as earthquakes, many bridge collapses have occurred in China, which has seriously affected people's personal safety and property safety
Because there are still a large number of steel structure bearings used on most buildings, the safety must be guaranteed
The seismic spherical steel bearings transmit force through the spherical surface, The bearing area is large, and the optimized combination of machine materials is adopted
Therefore, compared with other hinged structure bearings (such as swing bearing, roller bearing, etc
), its volume and height are greatly reduced, light weight, easy to install, and the cost is lower compared with the steel bearing with the same bearing capacity

Manufacturer of fixed seismic spherical steel bearing
Fixed seismic spherical steel bearing is a new type of bearing suitable for long-span and super long-span spatial structures
The bearing can bear large pressure and tension, and can realize freedom
Sliding and a certain degree of rotation can effectively release the temperature stress generated by the structure and meet the large deformation of the structure that may occur in the earthquake
The structure is compact and easy to install
It can work well with the upper support structure
