一、钢筋残余变形测定仪产品简介:

■**标准JGJ107-2010《钢筋机械连接技术规程》规定,通过圆柱套筒机械连接的两根钢筋,在单向拉伸试验中,接头的变形性能等级是一级时要求:残余变形u0≤0.10mm(钢筋直径d≤Φ32mm)和u0≤0.14mm(钢筋直径d>Φ32mm)。实际工作中测量到的残余变形一般在0.030mm至0.080mm之间。残余变形量很小。

■钢筋残余变形测试仪只有采用双侧引伸计测量得到的数据才是A准确的;

■双侧引伸计和钢筋之间只有采用弹性连接(例如:弹簧和皮筋套),这样测量得到的数据才是A可靠的。多次实验证明:采用机械式刚性连接虽然连接方便,但是测量的数据误差大,大于1%,重复性差,数据A靠,不能通过计量检定。

Product introduction:

■ ** The standard JGJ107-2010 "Technical Specifications for the Mechanical Connection of Steel Bars" stipulates that in a unidirectional tensile test, the deformation performance level of the joint is required when the two steel bars are mechanically connected through a cylindrical sleeve: residual deformation u0≤ 0.10mm (rebar diameter d≤Φ32mm) and u0≤0.14mm (rebar diameter d> Φ32mm). The residual deformation measured in actual work is generally between 0.030mm and 0.080mm. The amount of residual deformation is small.

■ The data of the steel bar residual deformation tester is accurate only when it is measured by a double-sided extensometer;

■ Only elastic connection between extensometer and rebar (for example: spring and rubber band), the data obtained by this measurement is reliable. Many experiments have proved that although the mechanical rigid connection is convenient for connection, the measured data has a large error, greater than 1%, poor repeatability, data A is reliable, and cannot pass the measurement verification.
