0.引言现浇空心楼盖是一种按一定规则放置内模后经浇筑混凝土而形成内有空腔的楼盖,这种埋入式内模有空心、实心筒体和空心箱体多种形式。现浇混凝土空心楼盖结构具有减轻自重、降低地震作用、提高隔热隔声性能等优点、可较明显地降低总体造价,并改善使用功能。近年来,这种结构已广泛地应用于商场、办公楼、图书馆、教学楼、停车库、住宅等建筑中,尤其适用于具有大跨度柱网、大荷载结构,对层高、总高有限制要求的公共建筑、住宅建筑和工业建筑。
0. Introduction Cast-in-situ hollow floor is a kind of floor that has been filled with concrete after being placed in the inner mold according to certain rules to form the cavity inside. This kind of buried inner mold has hollow, solid barrel and hollow box. form. The cast-in-situ concrete hollow floor structure has the advantages of reducing the weight, reducing the earthquake effect, improving the insulation and sound insulation performance, etc., and can obviously reduce the overall cost and improve the use function. In recent years, this structure has been widely used in shopping malls, office buildings, libraries, teaching buildings, parking garages, and residential buildings. It is especially suitable for large-span column nets and large load structures. Restricted requirements for public buildings, residential buildings and industrial buildings.
