Detailed Product Description: | Hengshui supply seismic spherical bearings, ball joints fixed seismic bearings, resilient steel ball bearings. Can also be processed according to your drawings made. Seismic spherical bearings, ball joints fixed seismic bearing Description: a seismic spherical bearing technical parameters: 1, bearing vertical bearing capacity into 300KN, 500KN, 1000KN, 1500KN, 2000KN, 2500KN, 3000KN, 4000KN, 5000KN , 6000KN, 7000KN, 8000KN, 9000KN, 10000KN fourteen levels; 2, bearing anti horizontal force of 20% vertical bearing capacity; 3, bearing anti vertical tension to 30% vertical bearing capacity; 4 Design Corner for 0.08rad (can be designed according to user requirements) 5, the radial displacement of the bearing ± 20mm- ± 50mm, ring to the amount of displacement ± 60mm- ± 100mm; 6, bearing sliding friction coefficient μ≤0.03 ( -25 ℃ - + 60 ℃); 7, bearing rotational friction coefficient of μ = 0.05-0.1 two seismic spherical bearing of the main technical performance: 1, can withstand the vertical load; 2, with anti vertical pull performance, ensure that the upper and lower vertical seismic structure is not out of line; 3, with anti horizontal force performance to ensure the horizontal seismic structure does not fall off; 4, can be adapted to the radial and circumferential displacement requirements; 5, can be adapted to the requirements of the corner in any direction; 6, the bearing has good shock damping properties; 7, the spherical bearing through the transmission of forces does not occur necking force acting on the lower structure of the reaction force is more evenly; 8, bearing no rubber bearing the impact of aging on rubber bearings does not exist, life long three ball bearing selection earthquake precautions to be taken: 1, should pay attention to the size of the bearing capacity of bearing selection, vertical tension size, horizontal size of the force and pay attention to the amount of displacement and rotation, should also pay attention to the level of damping bearing elastic stiffness. 2, should be chosen bearing note bearing types, namely two-way activity type, one-way activity, stationary. 3, constrained damping bearing gave direction to the displacement and stiffness, damping the need for the project. Four, seismic spherical bearing installation: 1, bearing installation program, connect the form and structure should be designed specifically agreed personnel to ensure the reliable connectivity and functionality substructure and bearing play. 2, the lower part of the reinforced concrete column label shall not be less than 40. 3, the column reinforcement should refer to the results of research and analysis of the bearing design, that is within the height range from the top of the column direction of the column foot in the direction of the column axis 0.25b to 0.6b in (b is the width of the column section), increasing Configuration section of the horizontal stirrups, which increases the amount determined in accordance with the results of capacity analysis. 4, bearing activities need to be set according to the design value between the upper bearing partial plate and skateboard. 5, when connecting embedded steel bearings and the use of a welding cooling measures to be taken, or on the side intermittent welding methods to prevent overheating and damage to the bearing steel Teflon plates, rubber seals and grease 5201 . 6, should make the elevation and the lower level of the structure to meet the design requirements before installation. Seat height is not greater than 1 mm corners. 7, bearing centerline should coincide with the center line of the main beam and substructure installation lines. 8, bearing installation in place, with embedded steel base plate welded to meet the design requirements. After beam construction to be completed, the temporary connections should be removed immediately. 9, must be on board with the connector bracket bearing plate installed under the seat is installed, bearing in place until after the completion of demolition, and immediately install the dust cover (dust cover for the rubber sheet, the same scene construction unit responsible for the installation). Five, seismic spherical bearing conservation: 1, Supports use on a regular basis during each check once, maintenance time. 2, check the bearing and the upper and lower connections if there is damage, check whether cut or loose bolts, welds are cracking. 3, check the dust cover dust inside the case and remove dust. 4, check the rubber seals with or without cracking and aging. 5, rotating the fixing nut, re-clean the oil to avoid rust. 6, check the bearing itself is highly variable, changes in reaction to this situation teflon wear plate, when the height changes more than 4 mm should be overhauled. 7, check the rust soundness and, if the application emery grind off the steel body and after showing a re-painted metallic luster. After eight special circumstances (such as an earthquake, damaging winds, etc.), should be checked above.
