钢筋混凝土结构中收缩裂缝浅探

Probe into the Shrinkage Cracks of the Reinforced Concrete Structure

钢筋混凝土结构中的裂缝主要出现在现浇钢筋混凝土楼板、走道板和女儿墙等部位,混凝土的收缩是钢筋混凝土结构产生裂缝或使裂缝扩大的重要因素之一,为防止收缩裂缝的产生或减少其发展,一般宜减少混凝土的收缩,并采取施工与构造上的处理措施。

The cracks of the reinforced concrete structure mainly occur in th e positions such as the cast-in-situ reinforced concrete floor plates, Walkway p lates, and the parapets, etc., and the shrinkage is one of the main factors maki ng the cracks occur in the reinforced concrete structure and making the cracks e nlarge. In order to prevent the occuring of the cracks and reduce the developmen t of the cracks, people should manage to reduce the shrinkage of and control the ir development, and adopt some countermeasures in the construction and the struc ture.
