混凝土结构后浇带的设置与施工

The Setting and Construction of the Ferroconcrete Structures' Late Moulding

为了解决钢筋混凝土收缩变形和温度应力的影响,通常是需要设置变形缝,但从建筑的艺术效果出发不希望设置缝.实践证明,通过设置施工后浇带(后浇施工缝),既可以解决大体积混凝土浇筑、超长建筑和高低相连建筑的中的施工问题,同时又可以解决高低或刚度极不均匀的两部分结构沉降变形的协调问题,从而有效的解决了这一矛盾.合理设置、精心施工、措施得当,确保后浇带的施工质量,才能真正实现其工程作用.

To solve the problems of the contraction distortion and the temperature stress, we usually set strain commissure, which is not expected when considering the art effect. Practice proved that setting the late moulding could efficiently solve the problems including constructing the large ferroconcrete moulding, the over--long architectures and the different--height--joined ones, the equilibrium of the sedimentation and distortion resulting from the different height and density. Only to make sure the construction quality by the reasonable setting, well constructing and proper measures can perform the function.
