Abstract

The invention discloses a combined type overhanging supporting structure which comprises a plurality of reinforced concrete columns and two reinforced concrete beams and further comprises a flower basket type overhanging I-shaped steel supporting mechanism and an overhanging I-shaped steel supporting mechanism. The flower basket type cantilever I-shaped steel supporting mechanism comprises a plurality of first embedded steel plates fixedly connected to the side wall of the reinforced concrete beam located on the upper portion. A first overhanging I-shaped steel, a second overhanging I-shaped steel, a third overhanging I-shaped steel, a fourth overhanging I-shaped steel, a fifth overhanging I-shaped steel, a sixth overhanging I-shaped steel and a seventh overhanging I-shaped steel are respectively welded on the side walls of the plurality of first embedded steel plates positioned at the reinforced concrete beam; the invention further discloses a construction method of the combined type overhanging supporting structure. The construction method comprises the following steps that S1, the basket type overhanging I-shaped steel supporting mechanism is hoisted to the installation position through hoisting equipment. According to the invention, the defects and problems of a floor type full-framing formwork are solved.
