板式阳台、雨蓬以及悬臂长度达1.2～1.5m的大挑檐等悬臂板结构,根部裂缝甚至产生断塌事故时有发生。引起悬臂板结构断裂塌落的根源是板面受力钢筋错位下移所致。因此,克服悬臂板受力钢筋错位下移,确保其埋设部位的准确性,是消除悬臂板结构断裂塌落隐患的关键。 一、原因分析 Plate decks, awnings, and cantilever plate structures with cantilever lengths ranging from 1.2 to 1.5 m in length, and even cracks in the roots sometimes occur. The cause of the failure of the cantilever plate structure to collapse is due to the dislocation of the plate surface stressed steel. Therefore, it is the key to eliminate the hidden dangers of the cantilever plate structure fracture and collapse by overcoming the positional displacement of the cantilever plate reinforced by the reinforcing steel. First, the reason analysis
