摘　　要：为解决钢筋套筒灌浆技术应用中出现的安装精度不高、难以大面积推广等问题,从现有规范中的安装允许偏差、套筒尺寸、预留钢筋直径及长度等设置方面着手,分析安装精度不足的原因,并建议通过加大钢筋套筒尺寸、提高规范中安装精度要求、调整垂直度偏差方向、使用定位模具等方式来提高预制构件安装精度,以供参考。To solve the problems in the application of reinforcement sleeve grouting technology,such as low installation accuracy and difficulty in large-scale promotion,the causes of insufficient installation accuracy are analyzed from the aspects of allowable installation deviation,sleeve size,diameter and length of reserved steel bar in existing specifications.It is suggested that the installation accuracy of prefabricated members can be improved by increasing the size of reinforcement sleeve,improving the installation accuracy requirements in the specification,adjusting the verticality deviation direction,and using positioning die.
