Compressive deformation on vertical displacement sensor reading taken four arithmetic mean of the typical load-deformation curve of the test machine shown 5000KN if Fig hinge bearing large initial deformation, which is generally due to the original intent of the bearing after assembly Part gap is compacted, but also because of the use of their hands Fiao vinyl sheet quality standards, its test large initial deformation caused by other factors, but ultimately the test load-deformation curve showing a linear relationship should be to meet the requirements. Spherical bearing horizontal load tests. Spherical bearings which use horizontal loads, load tests should be designed generally horizontal load of 1.2 chanting, test type spherical bearings should be placed in a central location test machine QZ spherical bearing plate bearing and self-balance sheet reaction frame and After the test device placed in place a horizontal force, the first pre-press, and then formally loaded. To ensure safety when loading, now added to the design of vertical bearing capacity of 50%, then to 0.5% as the initial design of the horizontal force thrust, then gradually loaded. Each record is loaded after a regulator dial indicator readings 2min design load of 90% of spherical bearings, and then added to the design of vertical bearing capacity capacity, then the level of force applied to the test load and unload the regulator after 3min QZ ( 09T) spherical bearing, the loading process three times in a row, horizontal load bearing deformation takes two dial indicator averages, as shown in the typical load-deformation curve 5000kn testing machine test, the test load bearing horizontal force deformation curve should linearly Guangxi. Spherical bearing friction coefficient test. After the completion of the new bearing replacement, in accordance with the same command to operate the jack so that the bottom surface is slightly higher than the temporary support beam pad, castings will be both temporary contact pads or titles, but then slow down the beam in place QZ (2009) spherical stand, when to relax jack to main cross relax, can not relax at the same time, to prevent damage to the bridge or individual jacks are crushed. Inspection and acceptance, clean up the site and replace the results of the task, removal of temporary working platform construction site or Fixture, comprehensive clean up the site, contact bearings worse tasks. In response to these construction steps, synchronous lifting bearing replacement work program are summarized in the role of load bearing on the construction, and there is a great difference in the role of a bridge built after the completion of the load bearing function in the study must consider the role of in the construction of external influence.
