Abstract

A structure construction apparatus including a frame unit, a formwork unit and a compacting unit is provided. The frame unit is provided on a ground on which a structure is to be constructed. The formwork unit is mounted on the frame unit, and maintains structural materials in a form to be constructed. The compacting unit is disposed to be adjacent to the formwork unit so as to compact the structural materials provided in the formwork unit. The formwork unit and the compacting unit are configured to move through the frame unit so as to automatically construct the structure.

First claim

What is claimed is:

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.

2. The structure construction apparatus of claim 1 , wherein the frame unit comprises:
vertical frames configured to erect at positions spaced apart at both sides, respectively, based on a construction position;
a horizontal frame provided horizontally relative to the ground between the vertical frames; and
a pair of movable frames each being configured to be movable in a vertical direction along the vertical frames, and
the formwork unit and the compacting unit are mounted to the movable frame.

3. The structure construction apparatus of claim 2 , wherein the frame unit further comprises:
a first rail installed between the vertical frames; and
a second rail installed between the pair of movable frames,
each of the pair of movable frames is configured to be movable in the vertical direction along the first rail,
the formwork unit and the compacting unit are configured to be movable in a horizonal direction along the second rail, and
the formwork unit and the compacting unit are configured to move to the construction position along the first rail or the second rail and to consecutively construct the structure.

4. The structure construction apparatus of claim 2 , wherein the frame unit further comprises a frame wheel mounted at a lower end of the vertical frame, and
the frame wheel is detachably mounted to one of the vertical frames and a height of the vertical frame is adjusted.

5. The structure construction apparatus of claim 1 , wherein the compacting unit comprises:
a guide portion connected to the formwork unit or the frame unit;
a compaction base configured to move along the guide portion; and
a compacting portion provided at one end of the compaction base,
the compacting portion is configured to perform a repetitive movement in a vertical direction within the formwork unit and to compact the structure material provided to the formwork unit, and
the compaction base is configured to move a position of the compacting portion in the formwork unit while moving along the guide portion.

6. The structure construction apparatus of claim 1 , further comprising:
a rotator positioned above the formwork unit and the compacting unit,
wherein the rotator is configured to change a construction direction by rotating the formwork unit and the compacting unit.

7. The structure construction apparatus of claim 1 , wherein the formwork unit comprises:
at least two formwork sub-plates spaced apart to face each other at both ends of the at least two formwork plates; and
a formwork sub-plate adjuster configured to move the formwork sub-plates in a vertical direction, and
each of the at least two formwork sub-plates is controlled in the vertical direction by the formwork sub-plate adjuster to open and close one of the both ends of the at least two formwork plates.
