This invention discloses a construction method for rapid positioning and installation of steel structure column caps, relating to the field of prefabricated building construction. The method utilizes a positioning assembly, pilot hole components, and a rebar connection assembly. The positioning assembly includes a positioning nut, a washer, and a strip steel plate. The strip steel plate has a hollow center for installing the pilot hole components, and the distance and extension height between different pilot hole components are adjustable. Four strip steel plates are arranged in pairs, with two plates overlapping the other two. Positioning nuts and washers are installed above and below the strip steel plates to securely connect the pilot hole components. A rebar connection assembly is installed at the lower end of each pilot hole component. Using this invention significantly saves manpower, material resources, and time costs, and offers advantages such as simple and quick installation and disassembly, standardized factory production, on-site assembly, good versatility, and strong construction adaptability.
