1. A structure construction apparatus comprising:
a frame unit provided on a ground on which a structure is to be constructed;
a formwork unit mounted on the frame unit and configured to maintain a structural material in a form to be constructed; and
a compacting unit provided to be adjacent to the formwork unit and configured to compact the structural material provided in the formwork unit,
wherein the formwork unit and the compacting unit are configured to move through the frame unit and to automatically construct the structure,
wherein the formwork unit comprises:
a formwork base movably mounted on the frame unit;
at least two formwork plates spaced apart to face each other at one end of the formwork base, wherein the formwork base is configured to move the at least two formwork plates to a construction position along the frame unit, and the structural material is provided between the at least two formwork plates; and
a formwork plate adjuster configured to adjust a separation distance between the at least two formwork plates,
wherein the formwork plate adjuster is configured to adjust and maintain the separation distance between the at least two formwork plates to match a thickness of the structure, and the formwork plate adjuster is configured to remove the at least two formwork plates from the structure when construction of the structure is completed,
wherein the formwork plate adjuster comprises:
a first ball screw horizontally provided at one end of each of the at least two formwork plates;
a second ball screw provided to be parallel to the first ball screw at another end of each of the at least two formwork plates; and
a bevel gear shaft provided to be orthogonal to the first ball screw and the second ball screw,
wherein both ends of the bevel gear shaft are geared at one end of the first ball screw and one end of the second ball screw, respectively, and the separation distance between the at least two formwork plates is adjusted by rotational driving of the first ball screw.
