STRENGTHENING REINFORCED CONCRETE PLATE BY EXTERNAL PRESTRESSING TECHNOLOGY
-
摘要: 由于功能改变、荷载增加,需对钢筋混凝土楼板进行加固。采用无粘结钢绞线体外预应力技术对楼板进行加固处理,实践证明,该方法能提高承载能力、加固效果好、施工方便。Abstract: Because of function change and increasing load, the reinforced concrete plates must be strengthened. The externalprestreeing strengthening technology of the plates by unbond steel strand is adopted, practice proved that this technology canimprove the bearing capacity, strengthening effect is good, and the construction is convenient.
