摘要
分析了收缩变形、温度变形在板内产生的约束拉应力是现浇板裂缝的主要原因,从施工图设计、混凝土原材料、配合比、养护等方面介绍了对楼板裂缝的影响因素,并提出了控制措施。
In this text the analysis show the retrained tensile stress in the floor slab is the mostly reason generating cast-in-situ concrete crack. The influencing factors of those cracks are introduced from construction documents design, the primary material of concrete, adaptation ratio, maintenance etc and the control measures are carried out.
