【摘要】 针对由变形变化引起的屋面梁板裂缝,采用增强结构的抗裂能力及减少材料收缩、允许梁板在一定范围内自由变位以减少约束、做好保温隔热等措施,即“抗”、“放”、“防”三种措施并用,设计与施工紧密配合,可以有效的控制有害裂缝。更多还原

【Abstract】 Aimed at controlling roofing beam slab crack due to deformation,this article puts forward the method of resisting,sla ckening and preventing.Here resisting means reducing shrinkage of material and strengthening crack-resisting ability of structure;slackening means reducing restric-tion and allowing deformation in certain area;preventing means taking s uck measures as heat preservation and thermal insulatio n.Through these methods and the comb ination of design and construction,harmful cracking can be controlled effectively.更多还原
