AN IMPROVED JIG ADAPTABLE TO A TENSILE TESTING MACHINE FOR CONDUCTING TENSILE TESTING OF WELDED REBARS

摘要

The invention relates to an improved JIG adaptable to a tensile testing machine for conducting tensile test of a plurality sized welded rebars, comprising: a base block (1) having a threaded through hole (6), an upper face, and two side faces; a holder (3) comprising a first end and a second end, the first end having a threaded portion matching with the threaded hole (6) of the base block (1) so as to releasably fix the holder (3) on the base block (1), the second end of the holder (3) being attached to the jaws (5) of the testing machine; a slide plate (2) having a first side and a second side, the first side comprises at least three holes (7) enabling the side plate (2) to be fixed to the base block (1) through correspondingly sized identical number of holes configured thereon (1), the second side of the side plate (2) having a single hole (9) with a size corresponding to that of a combined welded rebar (10) under testing; wherein the center of the single hole (9) is configured with an eccentricity corresponding to that of the combined welded rebar (10).
