[0002] Steel structure can be used as a rigid structure to bear structural loads and construction loads. It does not need to support or remove formwork during construction. It has the advantages of low cost and fast construction speed. Steel structure is widely used in high-rise building construction. With the continuous development of high-rise buildings, the requirements for high-rise steel structure construction are getting higher and higher, especially for high-rise buildings in high-intensity areas. Construction personnel need to face the design and construction optimization of complex steel structure nodes. Under the premise of ensuring the progress, quality and safety of the project, the construction rate of high-rise steel structure can be improved and the construction cost can be reduced. During the construction of high-rise steel structure, the formwork of the stairs is set up after the steel columns and beams of the steel structure are installed.
