First level classification
According to the structure of the project and the service performance of the bearings, the steel structure bearings are divided into four types: GKGZ, namely, steel structure seismic steel ball bearings, GJGZ steel structure seismic steel ball bearings, GKQZ steel structure seismic ball bearings, GJQZ steel structure seismic ball bearings
Secondary classification
Each type of bearing is divided into three types: two-way movable, one-way movable and fixed
Technical performance
Product Detail
Main technical performance of steel structure bearing:
1. It can bear vertical load;
2. It has the performance of resisting vertical tension to ensure that the upper and lower structures are not disconnected during vertical earthquake;
3. It has the performance of resisting horizontal force to ensure that the structure will not be disconnected during horizontal earthquake;
4. It can adapt to radial and circumferential displacement requirements;
5. It can adapt to the requirements of angle in any direction;
6. The shock absorption bearing has good shock absorption performance;
7. The support transmits the force through the spherical surface, without the necking phenomenon of the force, and the reaction force acting on the upper and lower structures is relatively uniform;
8. The bearing does not need rubber to bear pressure, and there is no impact of rubber aging on the bearing, so the service life is long.
Technical parameter
1. The vertical bearing capacity of the bearing is divided into
300KN、500KN、1000KN、1500KN、2000KN、2500KN、3000KN、4000KN、5000KN、6000KN、7000KN、8000KN、9000KN、10000KN
Fourteen levels
2. The horizontal resistance of the bearing is 20% of the vertical bearing capacity
3. Bearing vertical tension resistance: GKQZ and GJQZ vertical tension resistance is 20% of the vertical bearing capacity; The vertical tension resistance of GKGZ and GJGZ is 30% of the vertical bearing capacity
4. The design angle is 0.08rad (can be designed separately according to user requirements)
5 The radial displacement of the bearing is ± 20mm - ± 50mm, and the circumferential displacement is ± 60mm - ± 100mm;
6. Bearing sliding friction coefficient μ ≤0.03（-25℃-+60℃）；
7. Bearing rotation friction coefficient μ= 0.05-0.1 (GKQZ type, GJQZ type) μ ≤ 0.03 (GKGZ type, GJGZ type)
