建筑物钢筋混凝土结构的普遍应用,伴随着商品混凝土的推广,建筑楼面出现裂缝的机率在增加,日益受到社会人士关注;专家认为控制裂缝是个系统工程。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,寻找其成因,利于有目的进行裂缝控制。 With the widespread application of reinforced concrete structures in buildings, along with the promotion of commercial concrete, the probability of cracks in building floors has increased, and it has attracted increasing attention from the public. Experts believe that controlling cracks is a systematic project. The reasons for the cracks in the floor structure are complex, including materials, temperature changes, etc., as well as problems in design, construction, and use. The cracks in the floor along the pre-embedded pipelines in the floor have not attracted enough attention from the engineering staff to find the cause. Purposeful crack control.
