全现浇钢筋混凝土楼面板的裂缝是较难克服的质量通病,应从材料、设计、施工三大方面分析原因,提出楼面裂缝的综合性防治方法及具体措施。一、施工中重点加强部位(一)、最常见的裂缝发生部位。从现浇楼板裂缝发生部位分析,最普遍的是房屋四周阳角处的房间在离开阳角1米左右,即在楼板的分离式配筋的负弯矩筋以及角部放射筋末端或外侧发生45度左右的楼地面斜角裂缝,此通病在现浇楼板的任何一种类型的建筑中都普遍存在。(二)、原因分析及措施从设计角度看,现行设计规范侧重 All the cracks in the cast-in-place reinforced concrete floor is difficult to overcome the quality of the common problems should be analyzed from the material, design, construction three major reasons for the proposed comprehensive prevention and control of floor cracks and specific measures. First, the construction focus to strengthen the site (A), the most common site of cracks. From the cast-in floor cracks occur parts of the analysis, the most common is around the house around the corner of the room at a distance of about 1 m from the sun, that is, in the floor of the reinforced negative bending of the tendon and the corner of the radiating tendon occurred at the end or outside 45 degrees of floor bevel cracks on the ground, the common problem in any type of building cast-in-floor floor. (B), the cause of the analysis and measures From the design point of view, the current design specifications focus
