When developing inspection plans, the spread in rates should be determined and content according to the importance of bearing steel grid of roads and bridges, the bridge forms as well as the environment conditions, the structure and function of the bearings have a more comprehensive understanding rack mount design basis of the Internet, from a steel grid bearing changes and inspection structure, steel truss bearing re-review, at the same time, due to the steel truss bearing dust and debris around the Fall became the main reason for reduced bearing function every year, so often associated with cleaning and other maintenance work simultaneously checking is also very necessary. Steel truss bearing checker checks bearing basic process grid bearing, steel truss bearing checking instruments, appliances bridge bearing inspection is usually used, according to the purpose of the examination, steel truss bearing The inspection procedures for various checks, the definitions and requirements in respect of all checks are outlined below, regular checks, so-called regular checks abilities highway bridge maintenance work daily basis, to keep the steel truss bearing and its changes, while the daily inspection of the letter bearing or abnormal situations. Should be in the form of a special inspection, emergency treatment carried out. Once the changes in the new situation should be promptly cleaned or repair outside and check the degree of change and its causes from the surrounding circumstances, whether the repair and strengthening of early to make judgments bearing steel grid style is very important daily work. Bearing steel truss bridge caused damage is multifaceted grid bearing pads, generally considered the force acting on the bearing often exceeds the design requirements and design requirements exceed the deformation is the main reason, while the construction and quality management is not Perfection is one of the reasons, therefore, should be fully considered in the design of steel truss bearing force, displacement and use of the environment, but also the need to ensure construction quality. Steel truss bearing types and causes damage to the main aspects can be summarized as follows: steel truss bearing itself deformed bearing itself mainly due to structural deformation force curved bridge or ramp bridge complex, steel mesh rack mount stress generated at the uneven concentration. Not dense or mortar base plate corrosion, processing quality control is lax, bearing in itself flawed. Bolts, nuts deformation and shedding not tightened construction, corrosion, deformation, vibration considered inadequate. Sliding surface or rolling surface corrosion. pkpm grid bearings | grid bearing | manufacturers 13,833,855,982 provided by Hao Tong Engineering Rubber Co., Ltd. Hengshui.
