Steel truss bearing raw data collation and preservation, master design conditions bearing steel grid construction and installation conditions, changes and repair records and other information on the full bridge occurred in the past, to understand the function of the status quo bearing steel grid and the degree of change, repair time and the selected method, although it is a very complicated, complex and its important maintenance work, but this is a guiding significance for the future management of valuable information on vertical bearing slidably hinged seat, so I hope the information bridge full bridge design conditions and when completed will be collected and collated and reflected in future maintenance and management, save the file and resume information in a relatively long period of time off is very important. These records should include the following: bridge name, including bridges form area, line names, including schematic diagram of the bridge structure. Bearing steel grid form, dunks bearing type, bearing materials and steel grid layout and so on. Design conditions, including the steel truss bearing type 4000KN slidably hinge bearings, bearing materials and layout, and other design conditions, including the design of steel truss bearing reaction force, designed to slidably hinged bearing horizontal force, displacement, , bearing the features and use of the upper and lower steel grid standards, the amount of clearance center bearing and measuring temperature conditions. Bolt deformation or fracture of the main reasons, lack of strength bolts or bad material. Screws into the anchor not long enough or bad. Reaction force to bear insufficient stiffness of anchor bolts fatigue. Long-term repeated action live load fatigue. Although the appearance of the holder changes difficult to find a single bearing sliding parts to wear or aging, the material is sometimes the cause of performance degradation mount, in this case, bearing steel grid should also work to do it through the an appropriate judgment, the general criteria below. Steel truss mount quite fast extent investigation. As the administration or management of the bridge must pass bearing the extent of damage to the steel grid survey, and according to the survey results, considering the characteristics of the bridge connection configuration, after the use and size, the need for its repair can be single slide hinge bearings, repair or strengthening method is necessary to make the right judgments, steel truss bearing damage to determine the work program to check the process flow. Steel truss bearing damage assessment procedures, assessment procedures concerning the destruction of the bridge abutment, the current specification of highway bridges and culverts conservation bearing function has a relatively clear assessment criteria. In China's railway sector has assessed the standard railroad bridge and tunnel building.
