Main technical performance of steel structure supports:
1. Can bear vertical loads.
2. Features resistance to vertical tensile force, ensuring the upper and lower structures do not disconnect during vertical seismic events.
3. Features resistance to horizontal forces, ensuring the structure does not disengage during horizontal earthquakes.
4. Adaptable to radial and hoop displacement requirements.
5. Adaptable to corner requirements in any direction.
6. The shock-absorbing bracket has excellent shock-absorbing properties.
7. The bracket transmits force through a spherical connection, eliminating the phenomenon of force constriction, and the reactive forces acting on the upper and lower structures are relatively uniform.
8. The bracket does not use rubber to bear pressure, eliminating the impact of rubber aging on the bracket, resulting in a longer service life.
Steel Structure Support, Mesh Support, Seismic Ball Type Steel Support
Steel structure supports (also known as grid structure supports) are divided into four types: GKQZ type seismic steel ball supports, GJQZ type damping steel ball supports, GKGZ type seismic spherical steel supports, and GJGZ type damping spherical steel supports. Each type of support is further divided into three configurations: bidirectional movement, unidirectional movement, and fixed.
I. Main Technical Performance of Steel Structure Supports:
1. Can bear vertical loads.
2. Features resistance to vertical tensile forces, ensuring the upper and lower structures do not disconnect during vertical seismic events.
3. Features anti-lateral force performance, ensuring the structure does not detach during horizontal earthquakes.
4. Suitable for radial and circumferential displacement requirements.
5. Adaptable to corner requirements in any direction.
6. The shock-absorbing bracket features excellent vibration-damping properties.
7. The support transmits force through a spherical surface, eliminating the phenomenon of force constriction, resulting in relatively even reactive forces on both the upper and lower structures.
8. The bracket does not use rubber to bear pressure, eliminating the impact of rubber aging on the bracket, resulting in a long service life.
Section 2: Support Technical Parameters
1. The vertical bearing capacity of the supports is divided into 14 levels: 300KN, 500KN, 1000KN, 1500KN, 2000KN, 2500KN, 3000KN, 4000KN, 5000KN, 6000KN, 7000KN, 8000KN, 9000KN, and 10000KN.
2. The anti-lateral force of the support is 20% of the vertical bearing capacity.
3. Vertical tensile resistance of bracket
The GKQZ and GJQZ models have a vertical tensile resistance of 20% of their vertical bearing capacity.
The GKGZ and GJGZ models have a vertical tensile resistance of 30% of their vertical bearing capacity.
4. The design corner is 0.08 rad (can be designed separately according to customer requirements)
5. Radial displacement of the support ±20mm to ±50mm, circumferential displacement ±60mm to ±100mm.
6. Support sliding friction coefficient μ ≤ 0.03 (-25℃ to +60℃)
7. Support pivot friction coefficient μ = 0.05-0.1 (GKQZ type, GJQZ type)
μ ≤ 0.03 (GKGZ model, GJGZ model)
Section 3: Points to Consider When Selecting Steel Structural Supports:
1. When selecting a support, pay attention to the bearing capacity, the magnitude of vertical tensile force, the magnitude of horizontal force, and note the displacement and angular deflection. For vibration-damping supports, also pay attention to the horizontal elastic stiffness.
2. When selecting a bracket, pay attention to the type of the bracket, i.e., bidirectional sliding type, unidirectional sliding type, or fixed type.
3. The constraint directions of the shock-absorbing supports are both provided with displacement and stiffness, in accordance with the need for engineering shock absorption.
