现浇砼板设置"假缝"防止裂缝的可行性探讨

Discussion of Feasibility for Cracks Prevention through Making"Fake Crack" in Cast-in-place Concrete Roof

针对砖混结构住宅工程普遍存在的现浇楼板裂缝问题,分析了裂缝产生的原因,并引入砼道路工程设置"缩缝"(习惯称假缝)的做法到建筑结构中,探讨了"假缝"的设置对防止现浇砼板裂缝的可行性。

In view of cracks existed generally in floors and walls of cast - in - place dwelling house engineering, the author analyzes the reasons which caused cracks and put forward a method,just as done in road engineering, which can control cracks through making ＂fake crack＂ in cast- in- place concrete roof. Construction practice shows that it is effective an can give a reference to the design an d research of this kind of structure.
