现浇板裂缝的原因及控制措施

Causes and Control Measures of Cracks in Cast-in-place Slab

现浇板有整体性好,安全性高等诸多优点,但由于混凝土抗拉性差,易开裂。目前现浇板开裂已成为一种常见的现象,其不仅影响美观,还会产生渗漏等问题,影响建筑物的正常使用。严重的还会引起钢筋锈蚀,进一步影响结构安全性和耐久性。须对现浇板裂缝引起足够的重视。结合近年的工程实例,就现浇板裂缝的形成原因和裂缝的控制分析控制措施。

The cast-in-place slab has many advantages such as good integrity and high safety, but it is easy to crack because of its poor tensile properties.At present, casting cracks has become a common phenomenon, it not only affect the appearance, but also produce leakage and other issues, affecting the normal use of the building. Serious corrosion will also cause corrosion, further affecting the structural safety and durability. It is necessary to pay enough attention to the cracks in the cast-in-place slab. Combined with the engineering examples in recent years, the formation of cracks in the cast-in-place cracks and cracks control analysis and control measures.
