［摘要］長沙市巨星創(chuàng)業(yè)基地多層大跨度輕型工業(yè)廠房樓蓋采用裝配整體式鋼-混凝土組合空腹樓蓋結(jié)構(gòu)體系,該樓蓋主要由上層鋼筋混凝土肋板、下層T形鋼肋以及方形鋼管剪力鍵組成，上層帶肋板與下層鋼肋均在工廠預(yù)制。通過分析結(jié)構(gòu)的實際受力狀態(tài)，擬定了結(jié)構(gòu)在設(shè)計時需要采取的技術(shù)措施、設(shè)計要求以及施工工藝，并對關(guān)鍵構(gòu)件和節(jié)點的計算與構(gòu)造進(jìn)行了介紹。采用此種方法進(jìn)行設(shè)計能夠保證結(jié)構(gòu)的安全可靠，對相關(guān)工程設(shè)計有一定的借鑒作用。

Abstract: Prefabricated integral steel-concrete composite hollow slab structural system was adopted in the large-span multistory light industrial factory for Great Star entrepreneurship base in Changsha City. The system was made up of upper layer reinforced concrete rib-floor, lower layer T-shaped steel ribs and square steel tube shear key. The top prefabricated ribbed plates and bottom steel ribs were prefabricated in factories. Through the analysis of the structure under actual stress state, the technical measures, design requirements and construction techniques were studied. The calculation and structural details of key components and nodes were introduced. The structure is safe and reliable using this design method, which can provide some reference for engineering design.
Keywords: prefabricated integral; steel-concrete composite hollow slab; large-span multistory factory; structural design
