摘　　要：目前高层住宅楼工程中现浇混凝土楼板出现裂缝的现象已比较常见,特别是全现浇钢筋混凝土楼板的裂缝,是目前较难克服的质量通病之一。一般情况下,楼屋面裂缝表现为:龟裂状裂缝、跨中的纵向、横向裂缝以及阳角斜向45°裂缝等。轻则影响美观,重则危及房屋安全。根据近几年在工程中遇到的实际情况和查阅相关资料,对现浇混凝土楼板常见裂缝的产生原因和预防处理措施谈点粗浅的看法,供大家参考。There are cracks commonly seen in Cast -in -place reinforced concrete floor in the con- struction of high - rise residential buildings at present, especially whole cast - in - place reinforced concrete floor. It is one of common problems difficult to overcome now. Generally, cracks in the building floor show, such as, diffract form cracks, longitudinal cross cracks, transverse cracks, and angle 45° cracks and so on. The small cracks can affect beautiful appearance, but the large ones en- danger the safety of the buildings. The reason that there are cracks in cast - in - place reinforced con- crete floor and measures how to prevent cracks are given only for reference.
