Finished seismic unidirectional sliding support

Main performance of sliding bearing of finished space truss: 1
Vertical bearing pressure: 500 ~ 800000kn 2
Vertical pulling force: 500 ~ 800000kn 3
Horizontal shear force: 500 ~ 800000kn
The above three types of forces can be freely combined and selected according to the needs of the owner and the project
4
If necessary, the designed angle of support is 440
5 radian, which is equivalent to 0
06smn ~ 0
5 radian; if necessary, it can be designed as per the support angle
6
Friction control coefficient: & mu= 0
03 (normal temperature - 250 ~ 400) &mu= 0
005 (normal temperature － 600 ~ － 250) 7
Earthquake resistance: 7 ~ 11 degrees (designed according to regional and user requirements)
Price of damping sliding bearing - sliding spherical joint bearing of space truss - Hebei Compared with other bearings (such as plate rubber bearing, basin rubber bearing, etc
), qkgz spherical seismic bearing has large static stiffness
Under the action of huge self weight and inertial force, the bearing produces only minimal deformation, which can reliably ensure the force transmission of the building through the spherical surface, with large stress area, and the optimal combination of several materials
Therefore, compared with other hinged structure bearings (swing bearing and roller bearing), its volume and height are greatly reduced, It is light in weight, easy to install, and connects multiple towers compared with steel bearings with the same bearing capacity
Maintenance of finished grid sliding support: 1
Check and maintain the support regularly during its use
2
Check whether the support and the upper and lower connectors are damaged, whether the bolts are cut or loose, and whether the welds are cracked
3
Check the dust accumulation in the dust cover and remove the dust
4
Check the rubber sealing ring for cracking and aging
5
Rotate the fixing nut, clean it and then oil it again to avoid rust
6
Check the height change of the support itself, which reflects the wear condition of polytetrafluoroethylene plate
When the height change exceeds 4mm, it shall be overhauled
