[Universal rotation bearing vibration grid], [universal rotation elastic vibration grid holder] is the quality of the finished product company specializing in the design, vibration grid bearings are manufactured with superior first-class raw materials price concessions, welcomed the call vibration snapped a grid bearing, vibration rotation [universal] grid bearing design and manufacture of uniform principles of regular shape, both in plane or facade structure layout, have sought to make geometry, ductility regular uniform stiffness, improve the strength and ductility of the structure and components. Multi-channel vibration defense. Prevent brittle and unstable failure. Prevent material aging. High-quality manufacturing and installation. Second, the [universal] rotational vibration grid bearing material bearing structure, see detail. Stainless steel, Teflon slide, according JT391-1999 standard rubber seals and other regulations. Cast by GB / T11352-1989, GB / T14408-1993 standards. Third, the [universal] rotating seat vibration grid using anti-aging advantages of rubber bearings transmit force, not only play a role in damping, while meeting from the resulting corner bend. Be universal bearing can withstand the pressure, shear forces and pull in any direction. Can be universal rotation, to release the bending moment in any direction. Bearing force is mostly steel parts. Rubber mats are also produced by national standards with the rubber seal and air isolation, it is important bearing outer surface ocean-atmosphere-resistant, anti-ultraviolet embalmed, thus ensuring the seat in 60 years will not affect use. PTEF products bearing used, the friction coefficient is small, aging resistance, low temperature up to -150 ℃, ensuring the flexibility and slip bearing application in cold regions. Supporting Force focused, clear and not change with the angle. The role of the lower bearing structure (column, pier) by force. Seat height is low, favorable structural design of the building. Vertical bearing capacity of four indicators of performance parameters, rotational vibration [universal] grid bearing of: 500-80000KN vertical pullout: 500-80000KN horizontal shear: 500-80000KN above three types of force can be used to select the appropriate combination However, in special circumstances to be subject to review designs. Design Corner: 0.01-0.02rad friction coefficient: μ = 0.03 (normal temperature -25 ° ~ 40 °) μ = 0.05 (low temperature -60 ° ~ 25) [universal] rotational vibration grid holder is suitable for large-span spatial structure and large-span bridges, especially for wide bridge, curved bridge, the bridge of, especially for highly seismic areas of engineering structures. [Universal] rotating seat vibration grid is divided into four types: GKQZ seismic steel ball bearing type, GJQZ type damping steel ball bearings, GKGZ steel structure seismic steel ball bearings, GJGZ damping steel structure steel ball bearings, each type of bearing activities are divided into two-way, one-way activity, and three types of fixed type. Second, the [universal] rotational vibration parameters of a grid bearing, bearing vertical bearing capacity into 300KN, 500KN, 1000KN, 1500KN, 2000KN, 2500KN, 3000KN, 4000KN, 5000KN, 6000KN, 7000KN, 8000KN, 9000KN, 10000KN fourteen levels; 2, anti-bearing horizontal force of 20% vertical bearing capacity; 3, bearing anti-vertical tension: GKQZ type, GJQZ anti Vertical Rally for the vertical bearing capacity of 20%; GKGZ type, GJGZ anti vertical pull the vertical bearing capacity of 30%; 4, the design angle is 0.08rad (can be designed according to user requirements) 5, the radial displacement of the bearing ± 20mm- ± 50mm, hoop Bit Supply [universal] rotational vibration grid bearing manufacturing plant, steel truss supports, universal rotation bearing seismic grid, grid universal rotation damping bearings, bearing steel truss uplift
