Steel scaffolding performance test sliding fastener doing, when applied in the horizontal pipe (fasteners on both sides) to increase the vertical constant load P reaches the specified value, the measured displacement  1 and  2.

P is contained in the pre-loading 1.0kN, it will be adjusted to zero displacement measuring instrument. When P increased to 7.0kN, write down the value of  1; when P increased to 10.0kN, write down the value of  2. Fastening two a circular surface should be tested.

Experimental anti-sabotage: skid resistance tests, no damage to the damaged fastener can be used as performance tests against. At this point the lower fastener support attached a non-slip pad. When P is 25.0kN, the fastener must not damage the parts. test only a circular surface.

Slip Test: Test methods shall comply with the provisions of 5.2.1 of this guide book, preloading P should be 0.2kN. When P increased to 7.0kN, write down the value of  1; when P increased to 10.0kN, write down  2 values.

Fastener tensile performance tests on the sector: the increase in fastener under constant axial tension, measured displacement   upge0tp. When preloading P is 1.0kN, it will be adjusted to zero displacement measuring instrument, and then continue loading.

When P increased to 4.0kN, write down the value of . Base compression performance test: to 1.0kN / s speed of uniform loading. When P is 50.0kN, the base may damage. Test against damage: the skid resistance After the test, performance test for anti-sabotage. When P is 17.0kN, the fastener must not damage the parts.
