因钢筋在加工弯曲时有弹性,钢筋不会按照工程设计的意愿准确成型,这就需要研究并确定钢筋的反弹率,并将其应用在实际操作中,达到弯曲的钢筋按照工程设计的意愿准确成型。笔者通过本工程的实际经验总结出反弹曲率结论:钢筋直径越大,曲率越大;钢筋需成型的半径越大,曲率越大。 Due to the flexibility of the steel during bending, the steel will not be accurately shaped according to the engineering design’s intention. This requires studying and determining the rebound rate of the steel and applying it in practical operation to achieve accurate bending of the steel according to the design intention forming. The author summed up the rebound curvature through the practical experience of this project. Conclusions: The larger the diameter of the steel bar, the greater the curvature; the larger the radius of the steel bar to be formed, the larger the curvature.
