Detailed Product Description: | LYQZ tension and compression ball bearing is based QZ Universal series ball bearing, and in its creation of a new type of bearing tension device. It addition to Universal series ball bearing pressure, rotation, displacement and other functions, as well as to reduce the weight and resistance of the beam end due to centrifugal force, lateral sway force, horizontal wind, earthquakes and other produce vertical load bias tension and transverse shear force and so on, but also a reliable solution to earthquakes, typhoons, load bias and so off the beam and other issues, such as reducing the overturning like Harbin Bridge tragedy, can make use of the support beam load transfer process more stable , and the beam deflection recovery more reliable, thus ensuring the safe use of the bridge performance, improve bridge life. Mainly applied to curved bridge, steel bridge, and other serious load bias, bridges carrying high center of gravity position of the bridge design use; equally applicable to earthquake intensity does not exceed 80 degrees seismic regions using ordinary bridge. My company's technology developers through repeated calculations and finite element analysis, design and development of this product has gravity light, high and low, use of effective, and easy installation and maintenance. Technical performance of vertical bearing capacity of 24: 1500,2000,2500,3000,3500,4000,4500,5000,6000,7000,8000,9000,10000,12500,15000,17500,20000,22500,25000, 27500,30000,4000,5000,6000; bearing angle is 0.02rad (can be customized to allow large corner more products). Bearings can withstand the pulling force, the standard design is 30%, you can customize a variety of special products on the pulling force. Bearings can withstand the horizontal forces GD fixed bearing isotropic, DX-way movable bearing fixed to the horizontal bearing capacity of vertical bearing capacity of 20%; bearing displacement DX-way bearing activities, SX-way active support Block main bearing capacity according to the size of the displacement divided into ± 100, ± 150mm; DX-way bearing activities transverse displacement of ± 3mm; SX-way bearing activities transverse displacement of ± 40mm; (may need additional design ) DX-way bearing activities according to the needs of the beam, both for the activities of the transverse direction along the bridge to fix, but also for the transverse direction activities along the bridge to the fixed beam. Design of bearing friction coefficient values: room temperature (-25 ℃ ~ +60 ℃): u ≤ 0.03 low temperature (-40 ℃ ~ -25 ℃): u ≤ 0.05 Scope ball bearing grade steel bearing itself has to adapt to large span, steep curve bridge features. Standoffs can be adaptive within 6 ‰ slope requirements; beyond 6 ‰ slope can be embedded steel beam bottom set, or by the upper bearing plate according to the actual processing required to achieve the slope. The best option is through the use of specially designed to achieve a large slope, but need to be provided in advance using the installation location map designed to facilitate the design and manufacture. |
