Haichen supplies four hole shock-absorbing rubber bearings, four hole rubber bearings, seismic grid ball joint bearings, connecting gallery four hole spherical bearings quotation

Description :

　　The main technical performance of grid support:

　　1. Capable of bearing vertical loads;

　　2. Has the ability to resist vertical tension, ensuring that the upper and lower structures do not detach during vertical earthquakes;

　　3. Has the ability to resist horizontal forces, ensuring that the structure does not detach during horizontal earthquakes;

　　4. Can adapt to radial and circumferential displacement requirements;

　　5. Can adapt to any direction of turning requirements;

　　6. The shock absorber support has good shock absorption performance;

　　7. The support transmits force through the spherical surface without force necking, and the reaction force acting on the upper and lower structures is relatively uniform;

　　8. The bearing does not require rubber pressure, and there is no impact of rubber aging on the bearing, resulting in a long service life.

　　Technical parameters of rubber bearings for grid structures

　　1. The vertical bearing capacity of the support is divided into fourteen levels: 300KN10000KN;

　　2. The horizontal resistance of the support is 20% of the vertical bearing capacity;

　　3. The planned turning angle is 0.08rad (can be separately planned according to user requirements)

　　4. The radial displacement of the grid support, grid rubber pad, and isolation rubber pad is ± 20mm - ± 50mm, and the circumferential displacement is ± 60mm - ± 100mm;

　　The above skill requirements can be planned and produced according to customer requirements.

　　Precautions to be taken when selecting grid supports:

　　1. When selecting bearings, attention should be paid to the size of the bearing capacity, vertical tension, horizontal force, as well as displacement and rotation angle. For shock absorber bearings, attention should also be paid to the horizontal elastic stiffness.

　　2. When selecting bearings, attention should be paid to the type of bearings, namely bidirectional movable type, unidirectional movable type, and fixed type.

　　3. The restraint direction of the shock absorber support is given displacement and stiffness to meet the requirements of engineering shock absorption.
