楼地面出现裂缝对建筑物的美观和耐久性影响很大。建筑工程质量检验评定标准(ＧＢＪ301-88)规定:楼地面合格等级要求面层无明显裂缝,优良等级要求面层无裂缝,但是楼地面裂缝这一质量通病却在工程中比较常见,其形式一般可分为沿预制楼板板侧拼缝处产生纵向裂缝、沿预制楼板板端
Cracks in the floor of the building have a great influence on the beauty and durability of the building. The quality inspection and assessment standard (GBJ301-88) for construction projects stipulates that there must be no obvious cracks in the surface layer of the building, and the fine grade requires no cracks in the surface layer. However, the common problem of floor cracks is common in the project. It can be divided into longitudinal cracks along the side seams of prefabricated floor slabs, along the side of prefabricated floor slabs.
