[0021] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0022] As shown in Fig. 1, in one embodiment of the present invention, a structure 1 is formed of an expandable structural material 4 that is formed by expanding structural wires 2 into a predetermined space 3 through bending. With the above configuration, a structure 1 in which the structural wires 2 can be easily arranged can be realized. A configuration in which structural wires 2 made of steel or FRP (Fiber Reinforced Plastics) are used and bending is performed by plastic processing may be used. The operation of forming the expandable structural material 4 by expanding the structural wires 2 into the predetermined space 3 while bending it can be performed by an automatic device 5.

[0023] The structure 1 is formed of concrete and the deployable structural material 4 embedded in the concrete. According to the above configuration, it is possible to realize a concrete structure in which the structural wires 2 can be easily installed. In this case, the deployable structural material 4 is, for example, a reinforcing bar, an FRP bar, or the like.

[0024] The predetermined space 3 may be configured to follow a plane as shown in FIG. 1, or may be configured to follow a curved surface as shown in FIG. 2 in accordance with the shape of the desired structure 1.

[0025] The structural wire 2 may be configured to form a fractal curve (for example, a Hilbert curve as exemplified in FIG. 3). With the above configuration, an expandable structural material 4 having excellent strength can be efficiently formed. The fractal curve may be configured to expand in two dimensions or in three dimensions. In addition, the degree of the fractal curve is not limited to the first, second, and third degrees as exemplified in FIG. 4.

[0026] As shown in Figs. 5 and 6, the deployable structural material 4 may be configured to form a plurality of strips 6 (see Fig. 5) extending intermittently or continuously on paths 6a that are parallel to each other when viewed from a predetermined direction, and the interval X between adjacent strips 6 may be set according to the required strength. With the above configuration, the required strength of the deployable structural material 4 can be easily achieved by setting the interval X between the strips 6. The paths 6a of the plurality of strips 6 may be configured to be parallel to each other in a straight line as shown in Fig. 5, or may be configured to be parallel to each other in a curved line as shown in Figs. 7 and 8. In the example shown in Fig. 5, the strips 6 extend intermittently on the paths 6a. In the example shown in Figs. 7 and 8, the strips 6 extend continuously on the paths 6a from one end of the deployable structural material 4 to the other end.

[0027] As shown in Fig. 8, the deployable structural material 4 may be configured to form one or more layers of multiple strips 6. In order to form multiple strips 6 that will be an upper layer on top of the existing multiple strips 6, as shown in Figs. 9 and 10, the automatic device 5 may be configured to have a moving mechanism 7 that can move over the strips 6 in the lower layer. The moving mechanism 7 shown in Fig. 9 has a rotatable rotating part 7a, and the rotating part 7a has multiple legs 7b. The moving mechanism 7 shown in Fig. 10 has multiple legs 7b that can operate independently of each other.

[0028] As shown in Fig. 11, the structural wire 2 may be configured so that its diameter is adjusted by extrusion processing according to the required strength. With this configuration, when the structural wire 2 is bent and expanded into a predetermined space 3 to form the expandable structural material 4, the required strength of the expandable structural material 4 can be easily achieved by adjusting the diameter.

[0029] The deployable structural material 4 may be configured to form a single layer lattice pattern such as a rectangle (see FIG. 5), a triangle (see FIG. 12), or a hexagon (see FIG. 13) in one stroke if possible, or may be configured to form a hierarchical lattice pattern (see FIG. 14) in one stroke if possible. With the above configuration, the deployable structural material 4 having excellent strength can be efficiently formed. Note that a single layer lattice pattern or a hierarchical lattice pattern can be formed in one stroke if the lattice pattern corresponds to an Eulerian graph (all vertices of the connected graph have even degrees) or a quasi-Eulerian graph (two vertices of the connected graph have odd degrees). The deployable structural material 4 may be configured to form one or more layers of lattice patterns corresponding to an Eulerian graph or a quasi-Eulerian graph in one stroke.

[0030] 15(a) to (f), the deployable structural member 4 may be configured to have a lattice pattern that is alternately arranged to compensate for weak points, and if possible, formed in a single stroke. With this configuration, the deployable structural member 4 having excellent strength can be efficiently formed.

[0031] 1, in this embodiment, the construction method involves constructing a structure 1 formed of expandable structural materials 4 by an automated device 5 that forms expandable structural materials 4 by bending and expanding structural wires 2 into a predetermined space 3. According to the above configuration, a construction method that makes it easy to install the structural wires 2 can be realized.

[0032] As shown in Fig. 1, the automatic device 5 may be configured to bend and extrude the coiled structural wire 2, and then unfold it. According to the above configuration, the structural wire 2 can be efficiently stored in the automatic device 5, and therefore efficient construction can be achieved.

[0033] 1, the automatic device 5 may be configured to move and bend, extrude, and expand the structural wire 2. According to the above configuration, the expandable structural material 4 can be efficiently formed.

[0034] The automatic device 5 may be configured to bend and extrude the structural wire 2 so as to form a lattice pattern (preferably one or more layers) in one stroke, and then expand it. With the above configuration, an expandable structural material 4 with excellent strength can be efficiently formed. The automatic device 5 may be configured to bend and extrude the structural wire 2 so as to form a spiral shape in one stroke, and then expand it. For example, when constructing a structure 1 as a reinforced concrete pillar, the automatic device 5 may form the expandable structural material 4 as the main reinforcement in one stroke, or may form the expandable structural material 4 as the hoop reinforcement in one stroke, or may form the expandable structural material 4 serving as both the main reinforcement and the hoop reinforcement in one stroke.

[0035] 16, the construction method may be configured to form a first deployable structural member 4 in a first predetermined area 8 by a first automated device 5 arranged in the first predetermined area 8, and to form a second deployable structural member 4 adjacent to the first deployable structural member 4 in the second predetermined area 8 by a second automated device 5 arranged in a second predetermined area 8 adjacent to the first predetermined area 8, thereby constructing a structure 1 formed of the first deployable structural member 4 and the second deployable structural member 4. With the above configuration, rapid construction can be achieved by multiple automated devices 5.

[0036] 17, the construction method may be configured to use an automatic device 5 to unfold a first portion 4a of an unfoldable structural material 4 into a predetermined space 3, and then unfold the second portion 4b so as to cross the first portion 4a, thereby constructing a structure 1 formed from the unfoldable structural material 4. With the above configuration, a structure 1 having excellent strength can be efficiently formed.

[0037] 18, the construction method may be configured to deploy a first deployable structural member 4 in a predetermined space 3 by a third automatic device 5, and deploy a second deployable structural member 4 in the predetermined space 3 intersecting the first deployable structural member 4 by a fourth automatic device 5, and construct a structure 1 formed of the first deployable structural member 4 and the second deployable structural member 4. According to the above configuration, a structure 1 with excellent strength can be constructed efficiently by multiple automatic devices 5.

[0038] As shown in Fig. 19, the automatic device 5 may have an arm 9a provided on an erection device 9 (a device provided above the floor), and the structure 1 may be an erection structure (a structure provided above the floor, such as a wall, a pillar, a beam, a staircase, or a ceiling). With the above configuration, a construction method for an erection structure that allows easy installation of the structural wires 2 can be realized. The pillar can be formed, for example, from an expandable structural material 4 having a shape as shown in Fig. 20.

[0039] 21, the construction method may involve bending the second deployable structural member 4, which is deployed in a specified space 3 without intersecting with the first deployable structural member 4, by an automatic device 5 (which may be the same as or different from the automatic device 5 which deployed the first deployable structural member 4) so ​​that it does not slip out of the first deployable structural member 4, and constructing a structure 1 formed by the first deployable structural member 4 and the second deployable structural member 4. With the above-mentioned configuration, a structure 1 with excellent strength can be constructed efficiently.

[0040] 22, the construction method may involve bending the deployable structural material 4 deployed in a specified space 3 by an automatic device 5 (which may be the same as or different from the automatic device 5 that deployed the deployable structural material 4), and constructing a structure 1 formed from the deployable structural material 4. With the above-described construction, a structure 1 with excellent strength can be constructed efficiently.

[0041] As shown in Figs. 23 and 24, the automatic device 5 may have a material delivery mechanism 10 that delivers the structural wire 2 toward the predetermined space 3, and a bending section 11 that bends the structural wire 2 delivered by the material delivery mechanism 10 toward the predetermined space 3. With the above-mentioned configuration, the structural wire 2 can be efficiently bent and deployed into the predetermined space 3 by the material delivery mechanism 10 and the bending section 11. The material delivery mechanism 10 is, for example, composed of a pair of drive rollers that grip the structural wire 2 as shown in the figure. The bending section 11 may be configured to be capable of performing a shaping operation on the structural wire 2 from a curved shape to a straight shape, in addition to a bending operation and a bending operation of bending the structural wire 2 from a straight shape to a curved shape.

[0042] 23 to 24, the automatic device 5 may be configured to have a cutting section 12 that cuts the structural wire 2. According to the above configuration, the same automatic device 5 can be used to sequentially form a plurality of expandable structural materials 4 while cutting the structural wire 2 with the cutting section 12.

[0043] As shown in Figs. 23 and 24, the automatic device 5 may have a cross-sectional shape manipulation unit 13 for changing the cross-sectional shape of the structural wire 2. According to the above configuration, when the structural wire 2 is bent and unfolded into a predetermined space 3 to form an unfolded structural material 4, the required strength of the unfolded structural material 4 can be easily achieved by manipulating the cross-sectional shape, such as adjusting the diameter, with the cross-sectional shape manipulation unit 13. The cross-sectional shape manipulation unit 13 may be, for example, a drawing unit for adjusting the diameter of the structural wire 2 by drawing. The drawing unit may be configured to adjust the diameter of the structural wire 2 by gripping and pulling the structural wire 2 gripped by the material delivery mechanism 10. The drawing unit may be, for example, a pair of drive rollers for gripping the structural wire 2 as shown in the figure.

[0044] As shown in Fig. 23, the automatic device 5 may have a moving mechanism 7 for moving the bending section 11. According to the above-mentioned configuration, the structural wire 2 can be extruded and unfolded while being bent by moving the bending section 11 with the moving mechanism 7. In this case, the moving mechanism 7 may be configured to move the automatic device 5 itself as shown in Fig. 23. The moving mechanism 7 is not limited to a configuration having wheels as shown in Fig. 23, and may be configured to have, for example, two or more legs.

[0045] The automatic device 5 may have a material mounting section 14 on which the structural wire 2, such as a coil, is mounted. According to the above-mentioned configuration, the structural wire 2 mounted on the material mounting section 14 can be sequentially bent, extruded, and expanded.

[0046] 23, the automatic device 5 may be configured to form an FRP deployable structural material 4. In this case, the automatic device 5 may be configured to have at least one of a resin application unit that applies a room temperature curing resin or the like to the wire made of fibers, a curing unit that cures the resin impregnated in the wire made of fibers (for example, curing a thermosetting resin with heat or curing a photocurable resin with light), and a heat melting unit that melts the thermoplastic or other resin impregnated in the wire made of fibers with heat (for example, having a resin application unit and a curing unit).

[0047] The automatic device 5 may be configured to form an expandable steel structural material 4 (reinforcing bar, etc.). In this case, the automatic device 5 may be configured to have a material feeding mechanism 10 and a bending unit 11 that bends, by plastic processing, the structural wire 2 fed by the material feeding mechanism 10 toward the predetermined space 3. The automatic device 5 may also be configured to have a cutting unit 12, a cross-sectional shape operating unit 13, a moving mechanism 7, or a material mounting unit 14, or any combination of these.

[0048] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and the above-described embodiment can be modified in various ways without departing from the gist of the present invention.
