The invention provides a gymnasium roof steel structure installation method. The gymnasium roof steel structure installation method comprises the steps that S1, a steel structure is transported to a site; s2, steel column installation is conducted, and secondary grouting is conducted on steel column bottom feet; s3, pre-deformation values are reserved during machining and lofting of all splicing units of the truss, and trial hoisting is carried out after splicing is completed; s4, the main truss on one side of the opening and closing opening of the gymnasium is installed firstly, then the main truss on the other side of the opening and closing opening of the gymnasium is installed, and S5, prestressed inhaul cable construction is conducted after roof steel structure construction is completed. Steel columns used for supporting the main trusses are adjusted through nuts, secondary pouring is conducted after adjustment, so that the assembling accuracy and stability of the main trusses are guaranteed, a hoisting
