摘要： PURPOSE: A system and method for evaluating a contraction stress of concrete through measuring a deformation amount of the steel reinforcement are provided to accurately predict and evaluate with respect to cracks of concrete and to figure out a changing progress of a contraction stress at each material age. CONSTITUTION: A system for evaluating a contraction stress of concrete through measuring a deformation amount of the steel reinforcement comprises a concrete specimen(10), a tubular deformed bar(20), a deformation measuring gauge, and a deformation recording system(40). The tubular deformed bar is inserted in a longitudinal direction of the central part of a concrete test piece. The deformation measuring gauge is joined to the inner circumference of the tubular deformed bar. The deformation measuring gauge is connected to the deformation measuring gauge by a wire(35). A plurality of the deformation measuring gauges is joined to the inner circumference of the tubular deformed bar.

摘要： PURPOSE: Corner spacer and inside-spacer for vertical rebar, and a vertical-rebar installing structure for a concrete fire-resisting test are provided to prevent heat from entering through the lower part of vertical rebar and a sensor from exceeding a critical temperature, in a concrete fire-resisting test. CONSTITUTION: A corner spacer(100) for a vertical rebar comprises an inserting pipe(110) and a support(120). The vertical rebar is inserted into the inserting pipe. The support longitudinally fixes the inserting pipe. The support is extended by the coated thickness of the vertical rebar in the direction of an X axis and in the direction of a Y axis around the inserting pipe on a plane.
