When the ball joints on vertical seismic bearing capacity test universal ball joints rotate steel bearings, pot bearings Vertical Seismic Capacity Test hinged steel ball bearings, the general test load shall be 1.5 times the vertical load who test pot bearings should be placed in the tester load board central location in the test seat four symmetrically placed around the dial indicator to measure the deformation of the test apparatus vertical Yasu Austria, and with four pots ring indicator measuring radial deformation, When the test should first be pre-press, ball joint bearing preload is generally spherical hinge load bearing vertical design load, preload 3 times appropriate, conduct real load after preloading, the test loads from zero to test load evenly divided into 10, when tested to the design load of 0.5% or 1% as the initial pressure, and then progressively loaded ball bearing hinge read dial and dial gauge load data after each stage double entry elegant 2min Seismic sliding bearing steel ball joints until after the test load, unload and regulators 3min measuring residual deformation, the loading process by contacting three times, the ball bearing hinge vertical compressive deformation dial indicator readings were taken four arithmetic mean fixed Seismic ball bearing steel hinges, draw vertical pressure ring radial load deformation curve, the typical load-deformation curve. Vertical compression ball bearing hinge design load shall not be greater than 2% of the total height of seat, basin ring radial deformation is not greater than 0.05% pots ring radial diameter. The number of theoretical studies also wired, can learn from the data page is not so complete and perfect, however, in the country has been the emergence of practical engineering experience are constantly accumulating, especially the use of computer-controlled hydraulic construction process Synchronous Lift also in the development and continuous improvement, the ball bearing hinge the future of the aspects of the technology is expected to achieve rapid development of some ball bearing hinge bearing Synchronous Lifting replacement program is selected, the replacement bearing money, first under the bridge The structural features, with the change can be made when implemented do not operate equality. Ball bearing hinges should generally synchronous jacking construction is reasonable and reliable manner. Order of the equipment used, according to statistics, the ball bearing hinge various unfavorable factors should be taken into account to calculate the weight lifting more than twice as lifting equipment selected fundamental basis, that is, safe lifting equipment should absorb greater than 1.2.
