根据结构安全性检测鉴定结果,对带裂缝预应力混凝土空心楼板进行了加固方案设计,提出了加固结构计算模型。对采用粘贴玄武岩纤维布加固预应力混凝土空心楼板进行了全过程计算分析。结果表明:玄武岩纤维布加固预应力混凝土板可以达到提高结构承载能力的目的。
According to the results of structural safety inspection and identification, the reinforced plan of hollow prestressed concrete slab with cracks is designed and the calculation model of reinforced structure is put forward. The whole process of reinforced concrete hollow slab reinforced with basalt fiber cloth was analyzed. The results show that the basalt fiber reinforced plastic prestressed concrete slab can achieve the purpose of increasing the structural carrying capacity.
