摘要
着重介绍了一项专利技术——钢筋电子平均值引伸计,它的主要特点是标距可以在较大范围内作连续变化,能满足带肋钢筋机械连接试验的要求;另外还讨论了电子平均值引伸计的电桥的并联接法和串联接法的特点,以期对引伸计的研究、生产和选用提供参考。
A patented technology--electronic average extensometer for the rebar-reinforced was introduced. Its main characteristic is the gauge could be changed in larger range continuously. This characteristic can meet the requirement of mechanical connection test for ribbed steel bar. The parallel connection and series connection of electronic extensometer bridge were also discussed, it had reference value for the research, production and selection of extensometers.
