Steel bearing design manufacturers, steel truss supports, Fuyang steel bearings provided by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, ball bearing steel such as steel grid bearing structure is flexible, the amount of displacement is normal, is regularly checked the contents, the need for observation and measurement of their work process, so grid of steel supports, stressed the need to periodically check the parts close to the situation carefully Checker defect , which is subject to prior periodic inspection of the components necessary to create the conditions close to, such as the use of bridge inspection vehicle and the erection of temporary support measures light steel bearings, bearing parts only as close as possible to carry out a detailed examination. Regular inspection phase, the main emphasis of the steel truss bearing checking the following aspects; steel truss bearing assembly is intact, clean, with or without fracture, dislocation, void. Bearing steel grid is flexible, the actual amount of displacement is normal, fixed bearing anchor pin is intact. Steel truss support cushion stone style whether cracks. Simple stand is aging, cracking or failure. Bearing steel grid is aging, cracking, or without excessive shear deformation or compression rubber layer between each sandwich plate is uniform. No dirty when PTFE slide bearing, aging, tetrafluoroethylene board is intact, rubber block is drawn steel. Basin, steel truss bearing bolts are loose sliding steel bearings, cylinder pots exposed parts are rust, dust cover type No intact. It must not only requires seat location and extent of damage to figure out in advance, and after a full analysis study for the surrounding environment and traffic conditions bring, duration, spatial construction, bridge structures, construction methods and construction equipment to do a reasonable choice, block diagram shown in repair work research matters. Bearing steel grid location and extent of damage. Location and extent of damage to the bearing steel grid will directly affect the repair method is selected, so the first thing is to grasp the reasons for bearing damage is important. Different reasons damage repair methods are different, such as bearing steel grid itself due to constraints damage and deformation structure, should be added for its ability to ensure that the provisions of the displacement of the bridge design. If you are due to irrational use of bearing steel grid forms, such as bridges longitudinal slope greater than specification, and direct use of shelving, steel truss supports, beam bottom damage usually be adjusted, replace the steel mesh frame must be at the bottom of the beam bearing leveling process, then put on the rational design of bearing only, and can not simply be put on a do wrong, bearing damage caused by factors must be eliminated from the root. If the reason for the lower tectonic deformation caused, it must be taken into consideration to determine their future deformation Xu repair methods. That damping steel bearings, repair methods for type should have a clear and can not be stereotyped, otherwise fail to achieve the purpose and effect.
