现浇钢筋混凝土楼板裂缝产生原因与防治

The Cause and Prevention of Cast-in-Place Reinforced Concrete Floor Crack

近几年来,为了提高建筑的整体性和结构安全性,现浇钢筋混凝土楼板的应用越来越普遍,但同时也出现了个别楼板产生裂缝的现象.这些裂缝的出现不仅会影响楼板的抗渗效果,同时也极易侵蚀楼板内的钢筋,降低其耐久性.所以在建筑设计、材料选择、施工方法几大方面提出一些改进和防治措施,以改善施工方法为主、同时兼顾建筑设计和材料选择来控制和防止现浇钢筋混凝土楼板裂缝的产生.

In recent years,in order to improve the integrity and security of structure in the building construction,the application of cast-in-place reinforced concrete floor became more and more universal.But some individual cracks emerged in the meantime.These cracks not only affect impervious degree but also easily erode the steel bars inside the floors,and lessen the durability.Therefore,some improvements and prevention measures have to be proposed in building designs,material options,construction methods,among which the construction methods should be taken as the principal thing,and consideration should be given to building designs and material options in the same time.
