After assembly the appearance of flatness requirements, the bearing assembly exposed surface smooth, beautiful, uniform welds, attendance sheet and lower seat should be parallel to the ground plate, parallelism should be no greater than the diameter or the long side of 2%, with the lower attendance plate centerline sitting board centerline should coincide. Transport and storage, the seat assembly should be fixed, and transport, storage steel sliding hinge support, and installation shall be arbitrarily removed after assembly height deviation requirements. Corrosion, due to the hardness can not resist the acidic environment of the chloride ions and negative ions, and could easily be atmospheric ion erosion, especially in the supply environment, so to special protection, the installation should be preceded by cleaning surfaces, especially surfaces should be lubricated square value pollution. The basic provisions of the spherical bearing design, according to the national standard, bearing with PTFE sheet, high quality grease lubrication conditions in contact with the spherical steel and stainless steel friction coefficient reduction in the average stress is 30mpa, the design of friction coefficient should meet requirements under the concrete strength grade spherical bearings should generally not less than 40, must be arranged within a highly reinforced multilayer distribution range in the local branch bearing area under the seat type to withstand tensile stress of concrete splitting . Spherical bearing design principles, ball bearing design, the design of bridges and culverts not requested your prescription, do good introduction based on foreign experience and practical application. Water-cement ratio; grout mortar consistency is generally about 100mm more suitable. Single project due to different circumstances, should be determined before the construction of mortar consistency based on the design and construction requirements of the specific project, and from the measured strength of mortar mortar water consumption, water consumption should be strictly controlled. Mixing, stirring finished pouring cement mortar alternative construction in winter when low temperatures bidirectional slide hinge support, time, and conservation measures to be taken shall be determined in accordance with mild time taken humidification steam or other conservation measures, the curing temperature should not exceed 60 Other, other requirements unified board cement mortar, pouring cement mortar unidirectional sliding hinge support, construction of concrete considerations in engineering applications, Lovers and other prefabricated program, the most outstanding manufacturers recommended supply sales, to repair and make up Slide the hinge bearing repair works should repair, transmission repair part of the proposed clean. If the crack, crack depth fulfilled the seam kick net, removing slag debris, rinse with water, and keep it fully wet, when the seams, seam surface cleaned, washed with water and allowed to fully wet the surface of the need, if necessary fight hair until stones exposed position, when filled to the concrete pouring cement filling or coating or watering, pouring concrete, to be cast in concrete grout on the line together, be filled until after the initial setting of filling, coating or watering.
