公共建筑物的楼盖板与屋面板基本采用现浇钢筋混凝土的结构形式。由于混凝土施工工艺运用不当等原因,楼盖板面往往会产生裂缝,较严重时会影响结构的承载力、耐久性和安全性。如果缝隙从混凝土表面延伸至混凝土内部,将直接影响构件主要受力
Floor and roof panels of public buildings are basically constructed of cast-in-place reinforced concrete. Due to improper use of concrete construction technology and other reasons, the floor slab tends to crack, more serious will affect the structure of bearing capacity, durability and safety. If the gap extends from the concrete surface to the concrete interior, it will directly affect the main force components
