楼面结构出现裂缝原因复杂,有材料、温度变化等原因,也有设计、施工、使用等方面的问题,而楼面沿板内预埋管线出现的裂缝尚未引起工程人员足够重视。本人结合多年的工作实践,从设计及施工等多个方面对砖混结构的楼面裂缝产生的原因与防治措施进行了分析。 Cracks in the structure of the floor are complex and include material, temperature changes and other reasons. There are also problems in design, construction and use. Cracks in the floor along the embedded pipelines have not drawn enough attention from the engineering staff. I combine many years of practice, from the design and construction, and other aspects of the cracks in the brick structure of the causes and prevention measures were analyzed.
