[Seismic steel ball bearing hinge] install a basic requirement, cast beams [seismic] ball bearing hinge installation: 1. [seismic] ball joint bearing pad stone cleaning and adjustment: the first pier before receiving seat or the top surface of the stone bridge bearing pad to remove floating sand table, holding pad stone top surface clean and free of oil. If the elevation deviation stone piers support cushion is too large, use a dry hard cement mortar to be adjusted to ensure the accuracy and flatness pad stone elevation. [2.] The seismic ball bearing hinge mounted in place: on the support cushion design drawings marked by stone bearing centerline position, while the rubber bearings also marked cross the centerline. Stone pad design position on the line overlap placed on the rubber bearing pad stone, so bearing centerline and pier seismic sliding ball joint bearing products, bearing in place to ensure that accurate. . [Seismic] ball bearing hinge basic requirements 1. [seismic] ball joint bearing material, quality and must meet the design requirements and the relevant specifications, after passing before installation. 2. [seismic] ball bearing hinge plate leveling mortar performance should meet the design requirements, perfusion dense, may be left empty. 3. [seismic] ball bearing hinge down the longitudinal axis of each component must be positive. When installing the temperature and the design requirements are not at the same time, should stand along the bridge is set by calculating the amount of the pre-biased. 4. [seismic] ball bearing hinge not happen skew, uneven forces and void phenomenon. PTFE slide and stainless steel sliding surface may not have scratches, bumps and other seismic rolling ball bearing hinge professional system to do, the correct position, you must land on the grease oil before installation. [Seismic] ball bearing hinge construction unit qualification examination review site assembly, lifting and construction organization design and installation, focusing on the review of construction lifting equipment lifting capacity of construction technology measures the degree of control methods and vertical truss shape control measures, special lifting method should detailed process plan. Welding procedure qualification report examines the construction unit, welder certification, staff qualifications, including welding procedure qualification report form welded joints, welding methods and materials of coverage, welder certification of welding method, location, and other aspects of the validity content, must comply with the construction specifications, is strictly prohibited without certificate. Particular attention should be all-position welding welder must have a certificate, rather than a general horizontal position welding certificate. [Seismic] ball bearing hinge structure design drawings on the lower ball joint seismic slip bearing price, not only have abutments, pier itself, aside hole pattern, but also to draw a reference line around the bridge (or reference point) , so use him to determine the abutments, measuring baseline ball bearing hinge on the pier, but also the upper part of the construction of the main issues should be constructed, such as the length of the bridge, span long, diagonal size, [seismic ball hinged Block] centerline, seated position (center spacing), each bearing mounting direction, [seismic] underside ball bearing hinge design height and lower structure (support cushion stone) Top design height indicated on the design drawings. [Seismic] ball bearing hinge construction should pay attention to the problem 1) set aside the hole and bridge construction, when the lower part of the structure by different construction unit construction, lower structure construction unit, must fully consider the work of the next upper structure construction unit, When construction aside hole, certified in accordance with design drawings confirm the location, height, size, anchor bolt aperture, depth and verticality. Seismic slip the ball joint bearing price, ball bearing hinges, rubber-Run-Run Company is provided by Hengshui Rubber Co. project. Hengshui Guangrun Engineering Rubber Co.
