混凝土浇筑应连续不间断地进行,以免出现减弱结构受力性能及变形特征的施工缝。本文对惯用的“剪力较小”且“便于施工”的八字施工缝位置的留置原则提出商榷意见,并提出“便于施工”且“受力较小”的留缝原则。指出施工缝界面的技术处理方法和处理质量是保证施工缝能够安全可靠的关键及决定因素,并提出水平构件的施工缝不应一律做成竖直缝。 Concrete pouring should be continuous uninterrupted, so as not to weaken the structure of the performance and deformation characteristics of the construction joints. In this paper, we discuss the principle of indwelling the traditional “small shear force” and “easy construction” position and propose “easy construction” and “less force” Seam principle. It is pointed out that the technical treatment method and quality of the construction joint are the key and decisive factors to ensure the construction joint to be safe and reliable. It is also suggested that the construction joints of horizontal members should not be made into vertical joints.
