[0014] Hereinafter, embodiments of the present invention will be illustrated with reference to the drawings.

[0015] As shown in Figs. 1 to 2, in one embodiment of the present invention, in the method for manufacturing the structure 1, when manufacturing the structure 1 by arranging the dam material 3 and spraying the material 1a of the structure 1 onto the dam material 3, the dam material 3 is moved by the first power 4 in accordance with the spraying of the material 1a.

[0016] According to the above configuration, the dam material 3 is automatically moved to a position where it can receive the material 1a in accordance with the spraying of a material 1a such as cement-based materials like concrete and mortar (e.g., high-strength mortar containing steel fibers) by the first power 4 such as a robot, and is made to function as a movable formwork, thereby enabling the easy manufacture of a structure 1 such as a wall by spraying the dam material 3. Further, since the dam material 3 functions as a trowel, the finishing of the dam side surface 1b on the side opposite to the spraying side in the structure 1 can also be achieved simultaneously. In the illustrated example, the first power 4 is a robot having an arm 4a whose tip holds the dam material 3 and moves, but it is not limited to this, and for example, a self-propelled robot having a holding portion that holds the dam material 3 may also be used. The material 1a may be configured to have a cured material such as cement and a mixed material mixed with the cured material. The mixed material is, for example, inorganic fibers, organic fibers, aggregates (sand, gravel, etc.), foams, hardening accelerators, and the like. The structure 1 can be reinforced by inorganic fibers, organic fibers, and aggregates. The heat insulation property of the structure 1 can be improved by the foam. The hardening speed of the structure 1 can be improved by the hardening accelerator. In the manufacturing method of the structure 1 of the present embodiment in which the structure 1 is formed without using a formwork, it is preferable that the mixed material contains a hardening accelerator.

[0017] The manufacturing method of the structure 1 performs the spraying of the material 1a by a second power 5 such as a robot different from the first power 4. According to the above configuration, the spraying of the material 1a can be automated by the second power 5. In the illustrated example, the second power 5 is a robot having a nozzle 5a that blows out the material 1a, but it is not limited to this, and for example, a robot having a gripping portion that grips the nozzle 5a may also be used.

[0018] The manufacturing method of the structure 1 may be configured to finish the spraying side surface 1c on the spraying side in the structure 1.

[0019] The manufacturing method of the structure 1 may be configured such that the finishing of the spraying side surface 1c is performed by a third power (not shown), such as a robot, which is different from both the first power 4 and the second power 5. According to the above configuration, the finishing of the spraying side surface 1c can be automated by the third power. Before finishing the spraying side surface 1c, the functions of spraying and the movement of the dam material 3 may be interchanged between the first power 4 and the second power 5, and then the finishing of the spraying side surface 1c may be performed by the movement of the dam material 3 by the second power 5. According to the above configuration, the finishing of the spraying side surface 1c can be realized without separately preparing the third power.

[0020] The manufacturing method of the structure 1 may be configured such that the spraying of the material 1a and the finishing of the spraying side surface 1c on the spraying side are performed by a fourth power (not shown), such as a robot, which is different from any of the first power 4, the second power 5, and the third power. According to the above configuration, the spraying of the material 1a and the finishing of the spraying side surface 1c can be automated by the fourth power.

[0021] The manufacturing method of the structure 1 may utilize a plurality of combinations of the first power 4 for moving the dam material 3 and the second power 5 for spraying the material 1a, and the finishing of the spraying side surface 1c formed by the second power 5 of the first combination is performed by using the dam material 3 as a trowel by the first power 4 of the second combination (in this case, the first power 4 functions as the third power for the first combination), and the finishing of the spraying side surface 1c formed by the second power 5 of the second combination is performed by using the dam material 3 as a trowel by the first power 4 of the first combination (in this case, the first power 4 functions as the third power for the second combination).

[0022] Each of the first power 4, the second power 5, the third power, and the fourth power may be a self-propelled robot that moves by its own power, or a fixed robot that is moved by an external power. The structure 1 may be, for example, an outer wall, an inner wall, or a fence of a building. The structure 1 may also be a ceiling, a floor, a beam, etc. Appropriate shaping and patterning by processing such as cutting and painting may be performed on the surface (finishing surface) of the structure 1 with or without using the first power 4, the second power 5, the third power, and the fourth power.

[0023] The manufacturing method of the structure 1 is to arrange the reinforcing material 2, arrange the dam material 3 on the back side of the reinforcing material 2, and spray the material 1a. The reinforcing material 2 can be appropriately selected according to the specifications of the desired structure 1. For example, it can be composed of reinforcing bars such as steel bars and FRP (Fiber Reinforced Plastics) bars, reinforcing plates with or without an opening group, or reinforcing members composed of pipes in a lattice shape or other shapes. According to the above configuration, the dam material 3 arranged on the back side of the reinforcing material 2 is automatically moved to a position where it can receive the material 1a in accordance with the spraying of the material 1a by the first power 4 such as a robot, and functions as a movable formwork, so that the high-strength structure 1 in which the reinforcing material 2 is embedded can be easily manufactured. When manufacturing the structure 1 without arranging the reinforcing material 2, for example, by using a high-strength mortar containing steel fibers as the cement-based material 1a, the high-strength structure 1 can be easily manufactured.

[0024] The manufacturing method of the structure 1 may also be configured to manufacture the structure 1 by the coordinated control of the first power 4 and the second power 5. The coordinated control can be performed by a control device composed of a computer or the like (not shown). According to the above configuration, the manufacturing method of the structure 1 of the present embodiment using the first power 4 and the second power 5 can be automatically performed by coordinated control.

[0025] The structure 1 may be configured as a flat body or a curved body. The structure 1 may be configured as a curved body that extends in a curved shape in a horizontal cross-section, or may be configured as a curved body that extends in a curved shape in a vertical cross-section. The structure 1 may be configured such that a thick portion and a thin portion are continuously formed. In this case, the thick portion and the thin portion may be formed in a row so as to form a step, or may be formed smoothly in a row. The structure 1 may be configured such that a walled portion and an opening are continuously formed. In this case, the opening constitutes a window, for example.

[0026] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and the above-described embodiments can be variously modified without departing from the gist of the present invention.
