Square steel positioning table for fabricated steel structure building

The invention discloses an assembly type steel structure building square steel positioning table, and belongs to the technical field of steel structure buildings, the assembly type steel structure building square steel positioning table comprises a base assembly, a bottom plate is arranged below the base assembly, a square steel plate is arranged above the base assembly, and clamping assemblies are installed above the base assembly and located on the two sides of the square steel plate; the base assembly and the bottom plate are connected through a limiting buffer device, and a supporting and fixing device is installed on the outer side of the bottom plate. By arranging the limiting buffer device, the positioning table can prevent a square steel plate from shaking up and down through cooperation of a limiting frame and other structures when needed, normal operation of work is guaranteed, the positioning table can buffer vibration to a certain degree through cooperation of a damper and an elastic rubber frame,
