[Seismic] ball bearing steel design corner: 0.02rad. [Seismic] ball bearing steel can withstand a horizontal force: GD fixed bearing each direction, the direction of DX-way limit to the movable support for the bearing design vertical bearing capacity of 10%. Multi-seat each to the activity (DX), designed horizontal force DX unidirectional movable bearing activity direction is 5% bearing vertical design bearing capacity. [Seismic] ball bearing steel design displacement: the displacement of the main two-way movable bearing design displacement SX and DX unidirectional movable bearing structure along the direction of the lateral displacement of the ± 100mm and ± 150mm, SX-way movable bearing is ± 40mm KZQZ seismic steel ball bearing quality reach, DX-way movable bearing lateral displacement limit of ± 3mm. When the desired amount of displacement is not the same, special design; [seismic] activity bearing steel ball bearing design friction coefficient: room temperature (-25 ℃ ~ 60 ℃) low temperature (-40 ℃ ~ -25 ℃) μ≤0.03 μ ≤0.05 temperature range: -40 ℃ ~ + 60 ℃ 7, bearing Environment: Supports according to the environment can be divided into common type (for atmospheric environment) and corrosion resistant (suitable for the marine environment and severe atmospheric pollution Atmospheric Environment) seismic steel ball bearings, corrosion resistant bearings require filling in the model LQZ (NS) in order to make identification. [Seismic] ball bearing steel sloping requirements for beam KQGZ seismic steel ball bearing industry leading precast beam axle set way wedge plate bearing attendance topside to accommodate the slope of the requirements of the beam; situ beam the slope of the bridge by a concrete beam at the end adjustments, bearing the body does not slope. Seismic ball bearing steel has the following characteristics: the vertical stiffness, bearing good performance, stability supported bridge superstructure load; horizontal stiffness always, to meet the large displacement needs of earthquake; by adjusting the lead core area, you can change Damping the LRB's excellent than GQZ type seismic steel ball bearing technology, can effectively absorb seismic energy; in order to meet these performance requirements, the main performance parameters of lead rubber as follows: (1) a first shape factor of the first shape factor refers to the ratio of single-seat plane area and the lateral area of ??the rubber sheet is consistent with the general laminated rubber bearing shape factor, he decided the LRB compressive modulus of elasticity, usually the LRB's The first shape factor ≥15. (2) The second factor is the shape factor of the second shape refers side bearing area ratio of rubber bearing rubber planar area and the total thickness of calculation, the second shape factor is generally used to determine the stability of the holder The second factor is ≥5. (3) the allowable stress bearing allowable pressure depends di9er form factor and the maximum seismic displacement, should allow pressure is usually ≥8Mpa.
