Space frame steel bearing processing
That is, the supports used in steel structure engineering.
According to the structure of the project and the performance of the bearing, the steel structure bearing is divided into four types, GKGZ is the steel structure anti-seismic steel ball bearing, GJGZ type steel structure shock-absorbing steel ball bearing, GKQZ type steel structure anti-seismic steel ball bearing , GJQZ steel structure shock-absorbing spherical steel bearing
Each type of support is divided into three types: two-way movement, one-way movement and fixed type
The main technical performance of steel structure bearing:
1. Can carry vertical load;
2. It has the performance of resisting vertical tension, ensuring that the upper and lower structures are not disconnected during vertical earthquakes;
3. It has the performance of resisting horizontal force to ensure that the structure is not disconnected during horizontal earthquakes;
4. It can adapt to radial and circumferential displacement requirements;
5. It can adapt to the requirements of corners in any direction;
6. The shock-absorbing bearing has good shock-absorbing performance;
7. The bearing transmits the force through the spherical surface, and there is no force necking phenomenon, and the reaction force acting on the upper and lower structures is relatively uniform;
8. The bearing does not need rubber to bear pressure, there is no influence of rubber aging on the bearing, and the service life is long.
1 The vertical bearing capacity of the bearing is divided into
2 The horizontal resistance of the support is 20% of the vertical bearing capacity
3 The vertical tensile force of the bearing: the vertical tensile force of the GKQZ and GJQZ types is 20% of the vertical bearing capacity; the vertical tensile force of the GKGZ and GJGZ types is 30% of the vertical bearing capacity.
4 The design corner is 0.08rad (can be designed separately according to user requirements)
