摘要
很多校舍为预制板砖砌体结构房屋。预制楼板整体性较差,易引起楼板脱落,造成人员伤亡。通过对预制楼板房屋的破坏特点分析,对比板底粘碳布、楼板上加叠合层、板底粘钢板网、板底加钢绞线网等加固方法,得出预制楼板的板底粘钢板网既能增强整体效果,又能提高承载能力,同时解决了支撑长度不足的问题,是首选的加固方案。
Many school houses are of precast slab integral stability and where floor slab may collapse characteristics of house built of precast floor slab and and brick masonry structure which has relatively poor easily and cause casualty. After analysis on damage comparison among such strengthening methods as binding carbon cloth on slab bottom, attaching overlapped layer on floor slab, sticking steel sheet web or steel strand web on slab bottom, it is found that the method sticking steel sheet web on precast floor slab bottom is a preferred strengthening method, because it could not only increase integrity and improve bearing capacity, but also solve the problem of insufficient supporting length.
