Combined three-dimensional formwork for main body structure construction

The invention discloses a combined three-dimensional formwork for main body structure construction, which comprises a formwork main body for supporting a building template and supporting devices symmetrically arranged outside the formwork main body, and a driving assembly for driving the supporting devices and a transmission mechanism are arranged in the formwork main body; two vertical holes are symmetrically formed in the mold frame body, and the top of the mold frame body is in threaded connection with a pressing plate. The supporting device comprises first supporting plates, the two first supporting plates are symmetrically hinged to the outer portion of the formwork body, second supporting plates are hinged to the bottom ends of the first supporting plates, and inclined struts are hinged to one sides of the second supporting plates. The inclination angle of the second supporting plate is adjusted according to the inclined plane angle of a building body, concrete pouring work can be conducted after the fi
