一般砖砌女儿墙与屋面交接处容易出现水平裂缝,尤其是在平面阴阳角的部位产生得更早更严重。上海市第八建筑工程公司二分公司近年通过对十几个大小工程进行观察和施工实践,认为:①在软土地基上,建筑物不均匀沉降是女儿墙产生裂缝主要原因之一,它不仅使局部结构下沉拉裂出现水平裂缝,而且还造成垂直裂缝。所以在上海地区建造房屋,不仅需注重基础的整体刚度,还要认真做好基坑开挖、排水
Generally, horizontal cracks are likely to occur at the interface between the brick parapet wall and the roof, especially in the plane of the yin and yang corners. The second branch company of Shanghai No. 8 Construction Engineering Co., Ltd. has observed and practiced over a dozen of large and small projects in recent years. It is believed that: 1 The uneven settlement of buildings on soft foundations is one of the main causes of cracks in parasol walls. It not only makes The partial structure sinks and cracks horizontal cracks, but also causes vertical cracks. Therefore, building houses in the Shanghai area requires not only the overall rigidity of the foundation, but also the excavation and drainage of foundation pits.
