建筑工程最普遍的质量通病之一是建筑物楼面、墙体的开裂、缝隙统称裂缝。在众多混凝土裂缝中,有的超出设计与规范允许范围,影响到建筑结构的安全性、适用性,需要作整改处理。而大部分裂缝未超出其允许范围,对建筑结构不构成危害,可不作处理,但影响到建筑物的美学功能和使用功能。因此,有必要分析混凝土裂缝产生的原因,研究防止混凝土裂缝对策,防止此类质量通病的发生。一、房屋建筑工程混凝土裂缝主要出现在下列部 One of the most common quality problems in building engineering is the cracking of building floors, walls and cracks. In many concrete cracks, some beyond the scope of design and specifications allow, affect the safety of the building structure, the applicability of the need for rectification and treatment. However, most of the cracks do not exceed their allowable range, which does not pose any hazard to the building structure and can not be handled but affects the aesthetic and functional functions of the building. Therefore, it is necessary to analyze the causes of concrete cracks, to prevent cracks in concrete measures to prevent the occurrence of such quality problems. First, the housing construction works Concrete cracks mainly appear in the following department
