Once the changes in the new situation should be promptly cleaned or repair outside and check the degree of change and the circumstances surrounding its causes slip bearing steel truss early to make a judgment whether to repair and strengthen the steel truss bearing type is very important daily the work. Bearing steel truss bridge caused damage is multifaceted, generally considered the force acting on the bearing often exceeds the design requirements and design requirements exceed the deformation is the main reason, but imperfect construction and quality management is also one of the reasons, Therefore, the design should take full account 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 truss factory shipments slip bearing, bearing itself is flawed. Bolts, nuts deformation and shedding not tightened construction, corrosion, deformation, vibration considered inadequate. Sliding surface or rolling surface corrosion. When the constituent members of the bolts, the protective plate and other steel truss bearing when damaged, generally only the damaged portion of the member to be replaced, called partial replacement. Part of the normal practice is to replace, press the processing requirements of a good substitution pieces, the steel truss bearing member has broken the eradication and complete replacement of the letter members in a short time, before the update, if the operation When the parts of the face is not enough security situation, respond temporary loss of function of parts reinforcement measures taken to ensure safety during use slip bearing truss, steel truss bearing replacement operation step method. Steel truss bearing repair and widening the base. When the steel truss bearing repair a wide variety of repair unidirectional sliding bearing grid, there are individual repair and welding parts repair, etc., while the seat base mortar to repair the damaged part of the main beam may be temporary top, the damaged part of the excavation, re-arrangement of the reinforcing steel pouring mortar, if there is less than the width of the base, you can simultaneously broaden the base construction. When welding steel truss bearing repair, you should use good weldability welding materials, and should pay attention to the impact of welding temperature on bearing steel grid itself and the other constituent members, burns and other issues should not occur. If the welding conditions are relatively poor, should be determined by testing its construction methods, soldiers should comply with the relevant provisions of welding. Steel truss bearing repair and widen the base of the construction program. One-way grid Sliding Bearings | grid Sliding Bearings | Hao-Hao Rubber pass by Hengshui Rubber Company.
