The Construction Technology of Column Replacement Integral Accumulation Sliding at Uneven Elevation for Steel Structures

Abstract

Steel structures have been widely used in large public venues and super-high-rise buildings due to their strong spatial flexibility, good seismic performance, and beautiful appearance. For buildings with high lighting requirements, such as shopping malls, stadiums, and exhibition halls, a super-large day-lighting roof with light-transmitting steel structures is to be designed on top. However, it is impossible to directly hoist large steel structures with cranes in buildings, and the installation of steel structures at uneven roof elevations usually requires full hall scaffolding, which is inefficient and time-consuming. Based on the existing construction methods, this paper proposes a construction technology for column replacement integral accumulation sliding at uneven elevations for steel structures. This technology can improve the construction efficiency and reduce the construction cost of steel structures at uneven elevations.
