钢-混凝土组合结构在室内改造工程中的应用

Application of SRC Composite Structure in Indoor Renovation Engineering

甘肃兰州某商厦由于使用功能的改变,需要将天井封堵,增加楼板,从而增加商厦营业面积。采用钢-混凝土组合结构进行改造,介绍了钢-混凝土组合结构在改造工程中的节点设计和构造处理。实践证明,型钢组合结构由于强度高,结构自重相对较轻,湿作业量小,施工周期短,在加固改造工程中有广泛的应用前景。

Because of modification of using function in some building in Lanzhou city, Gansu province, SRC composite structure are used to seal patio and add floors to enlarge using area of the building. The author shows design and construction of joints in SRC composite structure in indoor renovation engineering. The practice verifies that SRC composite structure has good application prospect in renovation engineering because of its high strength, light self-weight, fewer wet working amounts and short construction periods.
