近年来,许多高层商住楼、商办楼的结构设计,往往底下几层框剪内筒筋混凝土结构,以满足商场大空间的需要,通过四层或五层的结构转换层作为承标准层(剪力墙)隔墙的技术转换措施。此种类型结构主要特点为钢筋密集,混凝土一次灌入量大,施工缝留置难度大,模板、排架支承体系要求高,所以认真、周密、合理的采用施工措施,对保证结构转换层的质量及整个高层主体工程质量有着极其重要的作用。
In recent years, many high-rise commercial and residential buildings, commercial buildings in the structural design, often under the frame of shear reinforced concrete structures to meet the needs of shopping malls large space through the four or five-story structure of the conversion layer as a standard layer (Shear wall) wall technology conversion measures. The main features of this type of structure for the intensive steel, concrete pouring a large amount of construction joints stay difficult, template, rack support system demanding, so serious, careful and reasonable use of construction measures to ensure the quality of the structure of the conversion layer And the quality of the main high-level project has an extremely important role.
