在施工过程中,常由于砌体的基础未能同步沉降,导致墙体的相关部位出现裂纹。我们施工过的两栋厂房就相继发生了类似情况。一个工程是压铸厂主厂房,单层钢筋混凝土排架结构,柱顶标高8.4米,纵向3跨,跨距各15米。每跨都设有1台吊车。厂房端部为两层砖混辅助间,虽然辅助间与主厂房两侧的围护墙之间留有伸缩缝,

In the construction process, often due to the foundation of the masonry can not be synchronized settlement, resulting in cracks in the relevant parts of the wall. Similar cases occurred in the two factories that we constructed. A project is die-casting factory buildings, single-story reinforced concrete rack structure, the top elevation of 8.4 meters, 3 vertical, span of 15 meters. Each cross has a crane. The end of the plant is a two-story brick and concrete auxiliary room, although there are expansion joints between the auxiliary rooms and the retaining walls on both sides of the main building,
