Construction Technology of Concrete Filled Steel Tubular in Shenyang Wanxin Building

Abstract:

Concrete filled steel tube is widely used in super high-rise steel structure, but there are many problem in the construction of concrete filled steel tube. With the construction of Wanxin building as an example, this paper described the selection of the construction program, and analyzed the disadvantages in construction such as the difficulties of concrete pumping and the problems of pipe blockage, pipe explosion and concrete curing during the process of construction. Based on structural characteristics and construction difficulties, the key technique of steel tube concrete construction are introduced in detail. It can provide significant reference and guide for super high-rise building construction.
