摘要
锚塞回缩是预应力钢筋混凝土施工中存在的普遍性问题,也是影响预应力值精度的主要原因之一。本文重点介绍预应力筋规范性张拉方法、锚塞回缩产生的原因、锚塞回缩对预应力值的影响程度以及对预应力值过大损失的处理方法和措施。
The anchor plug nerving is an universal problem existing in construction of prestressed reinforced concrete, is also one of main reasons having effect on accuracy of prestressed value. The paper＇s introduction centres on the methods for in specification stretching of prestressed reinforcements, the reasons for anchor plug nerving, the influence of anchor plug nerving on prestressed value as well as the treatments for serious losses in prestressed value caused by it.
