Seismic steel ball bearing is a bearing bridge bearing the earliest form. It consists of flat steel plates, steel plates in order to reduce friction on the contact surface, so as not to hinder the longitudinal sliding contact surface can be planed steel and coated with a graphite lubricant on the planer. The stereotype of thin steel plate sandwiched inspection, although helpful, but the stereotype is often squeezed out. If we can remove the dirt, dust, then inlaid with bronze self-lubricating graphite compound tablet will be able to work well. The amount of displacement of the single plate bearing is limited, and the support end of the beam can not be completely free to rotate. We determine the bearing disposal options based on the structural characteristics of the first bridge, around the web for the separation of structure, left and right, respectively, to operate the replacement pieces. Taking into account the structure of the bridge structure for the overall quality cast steel ball bearing damping find Guangrun, respectively, from the top to avoid shear failure on the deck should be used at the same time from the top way. From the top of the equipment used should be considered unfavorable influence of various factors, access to more than 1.2 times the weight of the lifting calculation as the basis for selecting device. Second calculated bearing compressive modulus of elasticity permissible value (actual compressive elastic modulus have been unable to test measured), calculate the value of a constant external load bearing upper bear bearing according to the shape factor. Preparation for construction (1) according to the determined construction program, good working platform construction site erection Guangrun damping steel ball bearings quality is good, the requirements of each seat to replace a set of two brackets erection, such as the replacement of the bridge abutment bearing requirements abutments and a pier locations of erection of a working platform to facilitate the construction and monitoring of the operator to use, the work platform to be solid and reliable, to ensure the safety of personnel. (2) carry out the jack, pump supporting calibration. This bridge calibrated total of 16 sets of flat jacks, including 14 from the top sets used for the other two to spare. (3) selection of the original holder of the same model new stand, and make a new test for detection of bearing work, supporting bearing dust cover. [Seismic] spherical steel ball bearing steel bearing installation rules for the operation of steel ball bearings [seismic] continuous beam steel spherical bearings, bearing before installation, you should check the connection status is normal bearings, accessories are complete, but not on any loose bolts under the seat. Continuous Beams gravity grouting method, the installation procedure is as follows: [seismic] ball bearing steel bearing pad before installation chisel stone wool surface mount parts in place, remove the debris aside and anchor holes water, grout installation template spherical bearing steel and bearing pad stone with water surface wetting. [Seismic] ball bearing steel wedge with a wedge bearing corners, placement and leveling seat and adjust the seat to the underside design elevation between the bottom surface of the support bearing pad stone should be left 20 ~ 30mm gap, grout installation template. 3. Carefully check bearing a central location and elevation with high-strength non-shrink grout material perfusion. 4. Using gravity grouting methods, perfusion and the lower bearing bolt hole gap, infusion process should be the central part of the supply of low qz bearing type ball bearing steel prices grouting around the factory until the periphery from steel and bearing plate gap filling material was observed all filled up. Steel ball bearings [seismic] perfusion before, should preliminary calculations required slurry volume, perfusion practical and calculated the number of slurry should not have too much error, should prevent midway lack pulp. [Seismic steel ball bearing] after filling is complete, the erection of greenhouses were required to heat conservation, and hang the thermometer, good temperature records, the curing temperature of not less than 5 ℃. Cattle subject to removal technicians and laboratory testimony before proceeding. Steel ball bearing steel ball bearings _ quote _ supply Guangrun Rubber Company provided by Hengshui Rubber Co.
