在建筑工程施工中,往往会因为混凝土沉降不均或者自身收缩而发生变形,从而威胁到整个建筑的质量安全。为了防止这种现象的发生,一般会设置后浇带,按照设计或者施工的规范要求,在基础底板、墙以及梁等适宜的部位设置临时的施工缝,将整个结构划分为若干个部分,在一定的时间后再浇筑混凝土,从而降低变形或者裂缝的产生,提高建筑工程的施工质量。
In the construction of the construction, often due to uneven settlement of the concrete or its own deformation and deformation, thus threatening the quality and safety of the entire building. In order to prevent the occurrence of this phenomenon, the post-pouring belt is usually provided. According to the design or construction specifications, temporary construction joints are to be provided on the appropriate parts of the foundation floor, the wall and the beam, and the whole structure is divided into several parts. After a certain period of time pouring concrete, thereby reducing the deformation or cracks, improve the construction quality of construction.
