After assembling the appearance of flatness requirements, after the exposed surface smooth sliding bearing assembly universal bearing activities (seismic) type, beautiful, weld uniform, attendance plate should be parallel to the ground with the lower seat board, parallelism should be no larger than the diameter or the long side of 2%, attendance plate centerline and the centerline of the next sitting board should coincide. Transport and storage, after sliding bearing assembly should be fixed, and transport, storage, 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, sliding bearing installation should be preceded by a clean surface, especially after lubrication should be squared value surface contamination. The basic provisions of sliding bearing design, according to the national standard, unidirectional sliding bearings with PTFE plate bearing activities (DX) type, in high quality grease lubrication conditions in contact with the spherical steel and stainless steel friction coefficient reduction In the mean stress 30mpa, the design should meet the provisions of the friction coefficient, concrete strength grade spherical bearings under generally not less than 40, are arranged within a multilayer sliding support local bearing area under the seat cushion type certain height range distribution of steel to withstand the splitting tensile stress of concrete. Spherical bearing design principles, ball bearing design, bridge design in our country do not have your prescription request, do a very good presentation based on foreign experience and practical application. Such as the three-hinged arch of the hinge can be eliminated by an elastic arch compression stress sliding bearing temperature changes and displacement caused by foundation settlement, meanwhile, reinforced concrete hinge design factors in addition to a good two-way bearing activities (SX) type, hinge function bad depends largely on the structure of detail treatment. Sliding bearing structure due to unreasonable treatment hinges, is not ideal, but cause structural damage examples are often present. Because concrete hinge sliding bearing has its unique advantages, so there are a lot of domestic and international engineering and technical personnel conducted a study to compare and analyze long-term. Made a lot of good advice and design. RC hinge bearing activities according to its structural form, there are multiple types of hinges, sliding bearings are used on various occasions in the case of a lot, but according to the requirements of its rotation is also unidirectional rotation and bi-directional rotation of the points. According to the information on some common reinforced concrete generally can be summarized as Metz resistant cell hinge is designed to pass through the hinge in reinforced neck pads, steel protected with cement mortar or concrete to prevent corrosion, sliding Supports single does not consider strengthening the role of reinforcement on hinge.
