Test Methods for Fastening Systems of High-Speed Railway – Part 7: Vertical Load Test for Cast-In Fastening Components1 ScopeThis Part specifies the indoor test method for the pull-out resistance for pre-embedded parts of fastener. This Part applies to fastening systems for high-speed railway.2 PrincipleA vertical load is applied to the pre-embedded parts of the fastener pre-embedded in the concrete; and the pull-out resistance of the pre-embedded part is determined by the load retention capacity during the test and the state of the joint between the pre-embedded part and the concrete after the test.3 Test Equipment3.1 Loading equipment The equipment with loading rate of 40kN/min~60kN/min, static loading capacity reaching 150kN, which applies the vertical load. 3.2 Load sensor The instrument that applies load to the pre-embedded part, with accuracy of Class-1.4 Test PieceSleeper with pre-embedded part of fastener, 1/2 sleeper or track slab (all described as sleeper in this test method).5 Test ProceduresFor the pre-embedded casing where the embedded parts are screwed in by bolts, the load shall ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
