Supports vertical compressive deformation displacement sensor reading taken four arithmetic mean displacement activity rubber bearing basin, the typical load-deformation curve on 5000KN testing machine shown if Figure, the initial deformation of the hinge bearing large, its original intent of the general To assemble the parts due to the bearing clearance is compacted, but also because of the use of their hands Fiao vinyl sheet quality standards, its larger and other factors caused the initial deformation during the test, but the final test load-deformation curve should exhibit a linear relationship 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 the center of the bearing plate tester position and balance sheet since the reaction frame and horizontal force test device After placed in place, the first pre-press and then subjected to formal loaded. To ensure safety when loading, vertical bearing capacity of universal design activities now rubber bearing basin added to 50%, then to 0.5% as the initial design of the horizontal force thrust, then gradually loaded. 2min after each record is loaded once regulator dial indicator readings 90% of the design load, and then the vertical bearing capacity is added to the design capacity, then the level of force applied to the test load and unload 3min after the regulator, the loading process of continuous three times the level of load bearing deformation takes two dial indicator on average, the typical load-deformation on 5000kn testing machine test curve shown in two-way activity pot rubber bearing, bearing horizontal force test should exhibit linear load-deformation curve in Guangxi . Spherical bearing friction coefficient test. The purpose of reliable delivery, the load of the lower structure having a sufficient strength, but also on the prepared hole can be filled sufficiently dense, they would not shrink from a gap brew phenomenon works agent harm to the repair material concerned The technical performance of their basic requirements. The main issues before the project construction materials should be noted that, for the technical performance grout proud full play to ensure the quality of repair works in the construction process focus special attention on the following aspects. Grass or discharge surface treatment carefully to ensure that the joint surface clean or nap. The surface layer of the concrete base to transport until early fall and hit the concrete surface to expose fresh hair and rinse pot rubber bearing activities, or re-use cross-sectional methods roughed treatment agent. Rotational displacement for the upper structure of the resulting deflection. Produce a corresponding bump in the free side of the rubber bearing. Laminated rubber bearings to withstand external force shown below, at any point within the carrier, by the design load Effect pot rubber bearing factory direct two-way activity _ rubber bearing basin _ activities rubber bearing basin by Hao Tong Rubber available.
