Kbqz spherical steel bearing manufacture

Technical parameters of steel structure grid support: the vertical bearing capacity of the support is divided into 14 levels: 300KN, 500kN, 1000KN, 1500KN, 2000kN, 2500kN, 3000kN, 4000kn, 5000kN, 6000kn, 7000kN, 8000kN, 9000kN and 10000kN
The horizontal resistance of the bearing is 20% of the vertical bearing capacity
Bearing resistance to vertical tension: gkqz and gjqz resistance to vertical tension is 20% of the vertical bearing capacity; The vertical tension resistance of gkgz and gjgz is 30% of the vertical bearing capacity
The design angle is 0
08 rad (it can be designed separately according to the user's requirements)
The radial displacement of the support & plusmn; 20mm-± 50mm, circumferential displacement & plusmn; 60mm-± 100mm； Features of fixed hinge support:
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

3
The fixed seismic hinge bearing shall bear the tensile, compressive and shear (transverse) forces
Under the action of huge random seismic force, as long as the upper and lower structures are not damaged, there will be no disastrous consequences such as falling beam and frame (generally speaking, the bearing is a weak link, and it is very easy to fall beam and frame under the action of strong seismic force, and the strength and ductility of this bearing are higher than that of the structure itself), Therefore, it is especially suitable for fortification in high-intensity seismic areas and has the ability to resist earthquake intensity of grade 9

The corridor support is mainly composed of upper base plate, lower base plate, spherical steel lining plate, displacement box, elastic damping parts, stainless steel plate and PTFE plate
It uses less steel, has small volume, and has relatively low finished products
It has the incomparable advantages of universal rotation, universal bearing and other types of bearings
Moreover, it adopts the special structure of tensile and shear resistance, and has the ability to resist the seismic intensity of 9 degrees
