KQGZ seismic steel ball bearing installation 1, the installation program of ball bearings, the connection should be in the form of personnel and structural design specifically agreed slip steel ball bearings to ensure a reliable connection and functional substructure and bearing play. 2, the lower grade of not less than reinforced concrete column 0. 3, the column reinforcement should refer to the results of research and analysis of the bearing design, that is within the height range of steering column capitals since the foot in the direction of the axis of the column of 0.25b to 0.6b (b is the width of the column section), increasing Configuration section of the horizontal stirrups, which increases the amount determined in accordance with the bearing capacity analysis. 4, according to the design bearing activities need to set the offset value between bearing plate and slide. 5, when connecting embedded steel bearings and the use of a welding, cooling measures should be taken, or on the side intermittent welding method to prevent overheating and damage to the bearing steel Teflon plates, rubber seals and grease 5201 . 6, should make elevation and the lower level of the structure to meet the design requirements before installation. Seat height is not more 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 plate welded to meet the design requirements. After construction pending beam bi-slip Liuzhou steel ball bearings, temporary connections should be removed immediately. 9 must be on the bearing plate and connector plates installed under the seat bearing is installed, bearing in place until after the completion of removal, and immediately install the dust cover (dust cover for rubber sheet, with on-site construction unit responsible for the installation). Seismic steel ball bearings particularly suitable for large-span spatial structure, large-span bridge, wide bridge, curved bridge, cable-stayed bridge, Wuhan-way slip ramp steel ball bearings, especially in the high intensity seismic zone is more applicable, while other types of bearings it is difficult to meet the requirements. Steel ball bearing slide on the pier layout principles bearing assembly in the whole process, the response of each component to be assembled in time to clean up, remove parts of the surface debris, grease, dust, etc., in order to ensure bearing assembly precision and quality. Simply supported box girder when the transverse beam bottom two rows of bearing center distance is less than 4m, can be located on two fixed bearing a pier, located two longitudinal activity on another pier supports. Simply supported box girder when the transverse beam bottom two rows of bearing center distance is greater than 4m, engraved on a pier set up a portrait of activities and a multi-directional bearing activities. Steel ball bearings should slide bearing and horizontal activities along the bridge as close as possible to the level of rigidity, so that the two bearings withstand the horizontal forces, or they may have fixed the main bearings to withstand the horizontal forces. Therefore, some foreign scholars have suggested that no transverse bearing activities, the level of force has to bear a fixed support. Simply slide the ball bearing steel support beam T in cross-section under the bridge near the center of the two pieces of T-beam, one end fixed bearing design, and the other end located longitudinally movable carriage, and the rest of various T beams, near the end of the fixed support Haikou bi-slip steel ball bearings, bearing horizontal activities located near the longitudinal end bearing activities, to set up multi-bearing activities. In the high-rise steel frame circular steel columns using concrete columns, beams and slabs of steel - concrete composite structure, total steel than ordinary steel has drastically reduced the amount of steel, can effectively reduce the project cost. Steel construction has the advantage of its decision will certainly have a strong vitality. Steel structure, manufacturing plant based, dry construction work, short duration, high degree of industrialization, pollution, no construction waste, in line with the development trend of the construction market. With the further development of the visible steel, steel structure worthy of use in multi-storey civil.
