Floor construction rapid support method capable of being reused

The invention belongs to the design technology of a building structure, and particularly relates to a floor construction rapid support method capable of being reused. The floor construction rapid support method comprises the steps that temporarily supported steel columns are arranged near walls of the periphery of a workshop room to be constructed, joint plates are preinstalled on the end portionsof the steel columns, steel beams are connected between the steel beams through the joint plates, and a steel frame system is integrally formed; and templates are laid on the steel beams of the steelframe, and a concrete floor is poured. The steel frame system formed by the steel beams and the steel columns can effectively support the load of upper floor construction, thus replacing the functionof a traditional scaffold. The steel columns of the steel frame are arranged by the side of the walls, and the steel beams are arranged by the floor bottom, so that the main space in the room is notaffected, and equipment can
