关于混凝土施工缝位置的商讨

Discussion on the Construction Joints Position of Concrete

混凝土浇筑宜连续不间断进行,以避免出现削弱结构受力性能及变形特征的施工缝。传统的施工缝位置一般留于"剪力较小且便于施工"之部位,此法存在一些缺陷和不足。针对这种情况,提出了"受力较小且便于施工"的施工缝位置留置原则。

Pouring concrete should be carried out without intermittence,so as to prevent the construction joints which may weaken the structure bearing performances and have deformation characteristic.The traditional construction joints are usually marked on the position with ＂smaller shearing and convenient for construction＂,however,this method has a few defects and shortcoming.Aiming at this situation,the setting principle of the construction joints position with ＂smaller loading and convenient for construction＂ is proposed.
