现浇混凝土结构工程因构造要求,经常设计一些待主要构件施工完成后再施工的现浇构件,如一些构造柱等。因为上部结构已经完成了混凝土的浇筑,造成后施工的构件施工难度增大,特别是与上部构件连接的后浇筑柱,很难保证顶部混凝土的密实度。在实际施工中为满足施工要求,采用以下办法。
Cast-in-place concrete structures due to structural requirements, often designed to be some major components to be completed after the construction of the cast-in-place components, such as some structural columns. Because the superstructure has been completed pouring of concrete, resulting in the construction of components after the construction of increased difficulty, especially with the upper member of the post-pouring column, it is difficult to ensure the density of the top of the concrete. In the actual construction to meet the construction requirements, the following methods.
