1、2013年第7期(总第285期)混凝土实用技术Number7in2013(Tota1No.285)ConcretePRACTICALTECHNOL0GYdoi:10.3969/j.issn.1002-3550.2013.07.040水泥复合砂浆钢筋网应用于抗剪加固钢筋混凝土梁技术罗利波(长沙市规划设计院有限责任公司,湖南长沙410007)摘要:用水泥复合砂浆钢筋网加固钢筋混凝土构件,是一种新的加固方法,该方法施工简单,施工便捷,施工工效高,湿作业少,不需大型施工机具,施工占用场地少,施工质量容易保证,经济效益好,价格便宜
2、,具有极佳的耐腐蚀性能、耐久性能和耐火性能,适用面广,可以广泛地适用于各种类型、各种形状、各种结构部位的加固修补,其本身可以起到对内部混凝土结构的保护作用,达到双重加固修补的目的,节省了大笔维修费用,而且解决了碳纤维加固中因使用有机界环氧化物而产生的问题。试验表明水泥复合砂浆钢筋网能改善梁的抗剪性能,加固效果良好。总结和讨论了水泥复合砂浆钢筋网抗剪加固钢筋混凝土梁的施工工艺及质量控制。关键词:水泥复合砂浆钢筋网;抗剪加固;施工工艺;质量控制中图分类号:TU528.O1文献标志码:A文章编号:1002—3550(2013)
