一、当前钢筋混凝土施工质量低劣主要表现在以下几个方面 :1.模板 :(1)底层支撑的地基夯实不够 ,立底模的垂直支撑常在混凝土浇筑时 ,水淋湿基土软化 ,使受力的支撑随之沉降 ,造成梁、板弯曲变形或裂纹等缺陷。 (2 )支撑系统失稳 ,使钢筋混凝土出现塌落。 (3)不进行模板设计 , First, the current poor quality of reinforced concrete construction mainly in the following areas: 1. Formwork: (1) The foundation of the bottom support compaction is not enough, the vertical support of the vertical formwork often pouring concrete, water wet soil softening, so that Subjected to the support of the settlement, resulting in beam, plate bending deformation or cracks and other defects. (2) instability of the support system, so that the concrete slump. (3) do not carry out the template design,
