一、送彩金38满100提现领取产品简介：

■国家标准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。

■送彩金38满100提现领取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。

First,the steel residual deformation tester product introduction:

■National Standard JGJ107-2010"Technical Regulations for Reinforcing Steel Connections"stipulates that two steel bars mechanically connected by a cylindrical sleeve,in the uniaxial tensile test,the deformation performance level of the joint is one level:residual deformation u0≤0.10 Mm(rebar diameter d≤Φ32mm)ａnd u0≤0.14mm(rebar diameter d>Φ32mm).The residual deformation measured in actual work is generally between 0.030 mm and 0.080 mm.The amount of residual deformation is small.

■Rebar residual deformation tester is only accurate when the data measured by the double-sided extensometer is used;

■Only the elastic connection between the double-sided extensometer and the steel bar(for example,spring and rubber sleeve)is such that the measured data is A reliable.Many experiments have proved that although the mechanical rigid connection is convenient,the measured data error is large,more than 1%,the repeatability is poor,the data A depends,ａnd the measurement cannot be passed.
