变形变化引起屋面梁板裂缝的控制
|
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。
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.
