植筋加固技术是一项针对混凝土结构较简捷、有效的连接与锚固技术;可以直接植入普通钢筋,也可以植入螺栓式锚栓;现在已管饭应用于已有建筑的加固改造工程中。如:施工中漏埋钢筋或钢筋偏离设计位置的不就,构件加大截面加固的补筋,上部结构扩跨、顶升对梁、柱的接长、房屋加层接柱和高层建筑增设剪力墙的植筋等等。

植筋后进行非破坏性拉拔实验,用来检测工作状态下的植筋质量,检测的数量是植筋总数的10%。检测中,测力计施加的力要小于钢筋的屈服强度、大于由设计部门提供的钢筋设计锚固力值。公式为:FM<FC<FYK(FC:测力计施加的力,N/平方毫米;FYK:钢筋的屈服强度,N/平方毫米;FM:植筋设计锚固力,N/平方毫米)检测实验合格后就可进行下道工序。
