[Slide] ball bearing steel process tanks mortar infusion set on the pier, to be seated on the rear seat and adjust the level, use epoxy mortar (by weight epoxy resin 6101 was 100, two small fat 17, ethylenediamine 8, sand 250) or high-grade cement mortar anchor bolt holes for perfusion and seat bottom cushion to be removed after hardening mortar used to adjust the level of the pad and pad with epoxy mortar to fill the position . Epoxy mortar requires infusion dense, may be left empty. [Slide] If the ball bearing steel welded connection, it should set a higher flatness embedded steel on pier and beam bearing pad stone, should set a certain number of two-way KZGZ seismic anchor bars on the embedded steel spherical steel bearing quotes, in order to ensure the compactness of concrete under the embedded steel, should be reserved for the vent on the right amount of embedded steel. Embedded steel edge length should be greater than the corresponding bearing, bearing plate side at least 50mm. The embedded steel and bearings, lower bearing plate segmented discontinuous welding, in order to avoid high temperature burn Teflon skateboards and grease. It should rust paint treatment after welding. [Slide] ball bearing steel installation should note the following: ① holder should be parallel with the centerline of the main beam centerline. ② bearing activities on the centerline lower bearing plate along the bridge direction should coincide, their crossing angle shall not exceed 5 '. ③ after the beam is installed, or in-situ concrete beam to form a plurality of seismic KZGZ spherical steel bearing manufacturers before tensioning prestressed beams after scrolling overall and reached the design seismic intensity KZGZ spherical steel bearing wholesale demolition on and lower abutment webs to prevent constraint beam normal rotation. ④ When installing local temperature and mean annual temperature is not the same, shall be determined by computing the holder along the bridge after the pre-offset value. 1.9.8, for bearing against dust, water after treatment, and then the construction of the upper structure. [Slide ball bearing steel] installation, pier and beam underside of the top surface should be clean, dry and free of oil, the installation process may not be affected bearing mechanical damage, burning, pollution and other unfavorable factors, the construction should be maintaining a uniform bearing force. [Slide] ball bearing steel used during regular inspections and maintenance every two years ① Check whether the shear bolt bearings, bearing displacement is normal. ② Check bearing rotating condition, whether abnormal angle. ③ Check the PTFE skateboard wear. ④ clear the debris and dust around the stand KZGZ seismic steel ball bearings and stainless steel surfaces with a cotton wipe the dust. ⑤ Remove the stand foot nut, clean oil, and then installed, in order to avoid nuts rust. ⑥ bearing conduct regular paint protection treatment (except stainless steel sliding surface). [Slide ball bearing steel] Overview With the increasing development efforts in western China, the construction of a bridge in the western region gradually increased, many large corner lot to build large slope bridge, a need for a more flexible rotation, can accommodate large steep slope Bridge curve bridge abutment. [Slide ball bearing steel] is based on common QZ series ball bearings, and bearing structure by setting a wedge-shaped structure, the spherical ball plate coated stainless steel plate to increase the flexibility of the rotation bearing itself, to meet the new bearing different slope, turn bridges needed. Vertical and horizontal bearing capacity of the bearing, the rotational torque, the key technical parameters of friction coefficient, PTFE slide bearing stress and mean stress edge, vertical compressive deformation are to meet the national standard GB / T17955-2000 "Ball Supports technical conditions "and the relevant provisions of the British Standard BS5400.
