[Technical Field]

[0001] The present disclosure relates to a structure in which a first layered structure and a third layered structure formed by stacking cement-based materials are arranged adjacent to each other in a direction intersecting the stacking direction, and to a building comprising this structure. [Background technology]

[0002] It has been known in the past to form structures such as walls, columns, beams, floors, or ceilings by layering cement-based materials using, for example, an additive manufacturing machine. For example, Patent Document 1 discloses the formation of multiple self-supporting walls formed by using a cement-based mixed fluid injected by a 3D printer (additive manufacturing machine).

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2024-25359 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the technology described in Patent Document 1, adjacent walls are arranged so that the protruding portions of one wall and the protruding portions of the other wall are staggered on the inside and outside when viewed from the room side. This means that the other wall can only be arranged linearly with respect to the first wall, which limits the types of shapes that can be used for the shaped object.

[0005] The present disclosure has been made in consideration of the above-mentioned problems, and aims to provide a structure formed by layering cement-based materials, which structure can have an increased variety of shapes. [Means for solving the problem]

[0009] Hereinafter, a structure according to an embodiment of the present disclosure will be described with reference to the drawings. The embodiment shows one aspect of the present disclosure, but does not limit the present disclosure and can be modified as desired within the scope of the technical concept of the present disclosure.

[0010] The object according to the present disclosure is a first layered object and a third layered object formed by layering a cement-based material using a layered manufacturing machine, and the first layered object and the third layered object are arranged adjacent to each other in a cross direction that intersects with the layering direction. First, an example of the configuration of the layered manufacturing machine 100 will be described with reference to FIG.

[0011] <Additive manufacturing machine> FIG. 1 is a diagram schematically illustrating an example of the configuration of an additive manufacturing machine 100. As shown in FIG. 1, the additive manufacturing machine 100 includes a nozzle 102, a movement mechanism 104, a supply pump 106, and a control device 108. The cementitious material M is, for example, mortar or concrete, and is produced by mixing water, cement, aggregate, and the like. The cementitious material M may be made from limestone, which is primarily composed of calcium carbonate, or may be made from gypsum, fly ash, blast furnace slag, molten slag, siliceous admixture, sewage incineration sludge, kaolin, incineration ash, or the like.

[0012] The nozzle 102 has an opening at its tip, and discharges the cement material M from this opening 102a. The movement mechanism 104 moves the nozzle 102 in any direction. Specifically, the movement mechanism 104 is an arm that supports the nozzle 102, and is electrically connected to a control device 108. When the arm moves in any direction in accordance with instructions from the control device 108, the nozzle 102 moves in both the vertical and horizontal directions.

[0013] The supply pump 106 supplies the cementitious material M to the nozzle 102. The supply pump 106 is electrically connected to the control device 108, and supplies the amount of cementitious material M to the nozzle 102 in accordance with instructions from the control device 108.

[0014] The control device 108 is a device for controlling the amount of cement-based material M discharged from the nozzle 102 and the movement of the nozzle 102 in order to form an additive manufacturing object having a desired shape. The control device 108 is a computer such as an electronic control device, and includes a processor such as a CPU or GPU (not shown), memories such as ROM and RAM, and an I / O interface. The processor of the control device 108 operates (performs calculations, etc.) according to instructions of a program loaded into the memory, and the control device 108 transmits instructions to each device (the arm and supply pump 106 described above) included in the additive manufacturing machine 100. In some embodiments, the control device 108 is configured to be able to receive signals for understanding the status of each device. In some embodiments, the control device 108 is a cloud server provided in a cloud environment.

[0015] In this disclosure, the additive manufacturing machine 100 will be described as manufacturing an additively manufactured object by layering cementitious material M in the vertical direction D1. In other words, the layering direction is the vertical direction D1. Each layer of the additively manufactured object is formed by continuously discharging the cementitious material M while moving the nozzle 102 (in a so-called single stroke). Each layer of the additively manufactured object may include a non-layered portion (such as a notch 18 described below) where the cementitious material M is not layered. The method for forming the non-layered portion is not particularly limited. The non-layered portion is formed, for example, by interrupting the discharge of the cementitious material M from the nozzle 102, moving the nozzle 102 to a predetermined position, and then continuously discharging the cementitious material M while moving the nozzle 102 again.

[0016] <Sculpture> The object 1 is assembled by combining multiple additively-modeled objects created by the additive manufacturing machine 100 described above. The object 1 is, for example, a wall, a pillar, a floor, a ceiling, or the like, and is a component that makes up a building. In this disclosure, the object 1 is described as a wall 1A(1) of a building, and the length direction of the wall is simply referred to as the "length direction D2," and the width direction (thickness direction) of the wall is simply referred to as the "width direction D3." The up-down direction D1, the length direction D2, and the width direction D3 are all perpendicular to one another.

[0017] FIG. 2 is a perspective view schematically showing the configuration of a portion of a wall 1A according to one embodiment. FIG. 3 is a perspective view schematically showing the configuration of a first layered object 2 according to one embodiment. FIG. 4 is a view of the first layered object 2 according to one embodiment as viewed from above. FIG. 5 is a perspective view schematically showing the configuration of a second layered object 4 according to one embodiment. FIG. 6 is a view of the second layered object 4 according to one embodiment as viewed from above. FIG. 7 is a perspective view schematically showing the configuration of a third layered object 6 according to one embodiment. FIG. 8 is a view of the third layered object 6 according to one embodiment as viewed from above.

[0018] As shown in Fig. 2, wall 1A includes a first layered object 2, a third layered object 6, and a rod member 90, all of which are formed by the above-described layered object manufacturing machine 100. The first layered object 2 and the third layered object 6 are arranged adjacent to each other along the longitudinal direction D2. In the example shown in Fig. 2, wall 1A further includes a second layered object 4, a fourth layered object 8, a fifth layered object 10, and a sixth layered object 11, all of which are formed by the above-described layered object manufacturing machine 100. The first layered object 2 to the sixth layered object 11 are layered objects formed independently of each other, and when combined, they form part of wall 1A (see Fig. 1).

[0019] The first layered object 2 will now be described. As shown in Figures 3 and 4, the first layered object 2 includes a plate-shaped first plate portion 12 and a first joint portion 20 integrally formed at one end portion 13 on one side in the longitudinal direction D2 of the first plate portion 12. This first joint portion 20 has a first space 21 extending in the up-down direction D1.

[0020] In one embodiment, as illustrated in FIG. 4 , the first plate portion 12 has a zigzag shape in which first one-side protrusions 14 protruding to the right and first other-side protrusions 16 protruding to the left are alternately arranged when viewed from above in the vertical direction D1. Each of the first one-side protrusions 14 and the first other-side protrusions 16 has a curved shape such that the outer shape changes smoothly over the entire length direction D2 when viewed from above. A first imaginary line L1 is a straight line passing through one end 12c and the other end 12d of the first plate portion 12. The first one-side protrusion 14 is a portion of the first plate portion 12 to the right of the first imaginary line L1 in the width direction D3. The first one-side protrusion 14 includes one end 12c of the first plate portion 12 and moves away from the first imaginary line L1 as it moves from the one end 12c of the first plate portion 12 toward the other side in the longitudinal direction D2, before returning to the first imaginary line L1. The first other-side protrusion 16 is a portion of the first plate portion 12 on the left side of the first imaginary line L1 in the width direction D3. The first other-side protrusion 16 includes the other end 12d of the first plate portion 12, and as it moves from the other end 12d of the first plate portion 12 toward one side in the longitudinal direction D2, it moves away from the first imaginary line L1 and then returns to the first imaginary line L1. The first one-side protrusion 14 is located on one side of the first other-side protrusion 16 in the longitudinal direction D2.

[0021] In one embodiment, a downwardly recessed notch 18 is formed in the upper surface 12a of the first plate portion 12. The lower end of the second plate portion 24, which will be described later, is fitted into this notch 18. The notch 18 is located in the center of the first plate portion 12 so as to be located at the boundary between the first one-side protrusion 14 and the first other-side protrusion 16. The depth of the notch 18 is not particularly limited.

[0022] In one embodiment, the first joint portion 20 has a cylindrical shape, as illustrated in Fig. 3. That is, the first joint portion 20 has an endless shape when viewed from above, as illustrated in Fig. 4. More specifically, the first joint portion 20 includes an arc portion 29 having a circular ring shape when viewed from above.

[0023] 3 and 4, the first layered object 2 includes an other-end-side first joint portion 22 that is integrally formed at the other end portion 15 on the other side in the longitudinal direction D2 of the first plate portion 12. The other-end-side first joint portion 22 includes an other-end-side arc portion 31 that has a circular ring shape when viewed from above, and has an other-end-side first space 23 that extends in the up-down direction D1.

[0024] As illustrated in FIG. 3, the first joint 20 is located between the upper surface 12a and the lower surface 12b of the first plate portion 12 in the vertical direction D1. The first joint 20 and the other-end first joint 22 are offset from each other in the vertical direction D1, and the other-end first joint 22 is located lower than the first joint 20. The lower surface 22b of the other-end first joint 22 is continuous with the lower surface 12b of the first plate portion 12. The lower surface 20b of the first joint 20 and the upper surface 22a of the other-end first joint 22 are positioned at the same or nearly the same level in the vertical direction D1. The upper surface 20a of the first joint 20 and the concave surface 18a of the notch 18 are positioned at the same or nearly the same level in the vertical direction D1.

[0025] The second layered object 4 will now be described. As shown in Figures 5 and 6, the second layered object 4 includes a plate-shaped second plate portion 24 and a second joint portion 32 integrally formed at one end portion 25 on one side in the longitudinal direction D2 of the second plate portion 24. This second joint portion 32 has a second space 33 extending in the up-down direction D1.

[0026] In one embodiment, as illustrated in FIG. 6 , the second plate portion 24 has a zigzag shape in which second one-side protrusions 26 protruding to the right and second other-side protrusions 28 protruding to the left are alternately arranged when viewed from the up-down direction D1. Each of the second one-side protrusions 26 and the second other-side protrusions 28 has a curved shape such that the outer shape changes smoothly over the entire length direction D2 when viewed from above. A straight line passing through one end 24c and the other end 24d of the second plate portion 24 is defined as a second imaginary line L2. The second one-side protrusion 26 is a portion of the second plate portion 24 to the right of the second imaginary line L2 in the width direction D3. The second one-side protrusion 26 includes the other end 24d of the second plate portion 24 and moves away from the second imaginary line L2 and then returns to the second imaginary line L2 as it moves from the other end 24d of the second plate portion 24 toward one side in the length direction D2. The second other-side protrusion 28 is a portion of the second plate portion 24 on the left side of the second imaginary line L2 in the width direction D3. The second other-side protrusion 28 includes one end 24c of the second plate portion 24, and as it moves from the one end 24c of the second plate portion 24 toward the other side in the longitudinal direction D2, it moves away from the second imaginary line L2 and then returns to the second imaginary line L2. The second one-side protrusion 26 is located on the other side of the second other-side protrusion 28 in the longitudinal direction D2.

[0027] In one embodiment, a downwardly recessed notch 30 is formed in the upper surface 24a of the second plate portion 24. The wall 1A includes an additive manufacturing object (not shown) that is disposed above the second additive manufacturing object 4, and the lower end of this additive manufacturing object is fitted into the notch 30. The notch 30 is located in the center of the second plate portion 24 so as to be positioned at the boundary between the second one-side protrusion 26 and the second other-side protrusion 28. The depth of the notch 30 is not particularly limited. Note that if the second additive manufacturing object 4 includes the upper surface of the wall 1A, the notch 30 may not be formed.

[0029] 5 and 6, the second layered object 4 includes an other-end-side second joint portion 34 that is integrally formed with the other end portion 27 on the other side in the longitudinal direction D2 of the second plate portion 24. The other-end-side second joint portion 34 includes a second other-end-side arc portion 37 that has a circular ring shape when viewed from above, and has an other-end-side second space 35 that extends in the up-down direction D1.

[0030] The third layered object 6 will now be described. As shown in Figures 7 and 8, the third layered object 6 includes a plate-shaped third plate portion 61 and a third joint portion 62 integrally formed at the other end portion 83 on the other side in the longitudinal direction D2 of the third plate portion 61. The third joint portion 62 has a third space 71 extending in the up-down direction D1.

[0031] In one embodiment, as illustrated in FIG. 8 , the third plate portion 61 has a zigzag shape in which third one-side protrusions 80 protruding to the right and third other-side protrusions 82 protruding to the left are alternately arranged when viewed from the up-down direction D1. Each of the third one-side protrusions 80 and the third other-side protrusions 82 has a curved shape such that the outer shape changes smoothly throughout the entire length direction D2 when viewed from above. A third imaginary line L3 is a straight line passing through one end 61c and the other end 61d of the third plate portion 61. The third one-side protrusion 80 is a portion of the third plate portion 61 to the right of the third imaginary line L3 in the width direction D3. The third one-side protrusion 80 includes one end 61c of the third plate portion 61 and extends from the one end 61c of the third plate portion 61 toward the other side in the length direction D2, then moves away from the third imaginary line L3 and returns to the third imaginary line L3. The third other-side protrusion 82 is a portion of the third plate portion 61 on the left side of the third imaginary line L3 in the width direction D3. The third other-side protrusion 82 includes the other end 61 d of the third plate portion 61, and as it moves from the other end 61 d of the third plate portion 61 toward one side in the longitudinal direction D2, it moves away from the third imaginary line L3 and then returns to the third imaginary line L3. The third one-side protrusion 80 is located on one side of the third other-side protrusion 82 in the longitudinal direction D2.

[0032] In one embodiment, a downwardly recessed notch 84 is formed in the upper surface 61a of the third plate portion 61. A lower end portion of a fourth plate portion 66 of a fourth layered object 8, which will be described later, is fitted into this notch 84. The notch 84 is located in the center of the third plate portion 61 so as to be located at the boundary between the third one-side protruding portion 80 and the third other-side protruding portion 82. The depth of the notch 84 is not particularly limited.

[0033] In one embodiment, as illustrated in Fig. 7, the third joint portion 62 has a cylindrical shape. That is, as illustrated in Fig. 8, the third joint portion 62 includes a third arc portion 85 that has a circular ring shape when viewed from above.

[0034] 7 and 8, the third layered object 6 includes an opposite-side third joint portion 63 that is integrally formed at one end portion 81 on one side in the longitudinal direction D2 of the third plate portion 61. The opposite-side third joint portion 63 includes an opposite-side arc portion 86 that has a circular ring shape when viewed from above, and has an opposite-side third space 87 that extends in the up-down direction D1.

[0035] As illustrated in FIG. 7 , the opposite-side third joint 63 is located between the upper surface 61a and the lower surface 61b of the third plate portion 61 in the vertical direction D1. The third joint 62 and the opposite-side third joint 63 are offset from each other in the vertical direction D1, and the opposite-side third joint 63 is located higher than the third joint 62. The lower surface 62b of the third joint 62 is continuous with the lower surface 61b of the third plate portion 61. The upper surface 62a of the third joint 62 and the lower surface 63b of the opposite-side third joint 63 are positioned at the same or nearly the same level in the vertical direction D1. The upper surface 63a of the opposite-side third joint 63 and the concave surface 84a of the notch 84 are positioned at the same or nearly the same level in the vertical direction D1.

[0036] In one embodiment, the third layered object 6 is manufactured by the layered manufacturing machine 100 using the same method as the first layered object 2, and has the same shape as the first layered object 2. In one embodiment, the fifth layered object 10 is manufactured by the layered manufacturing machine 100 using the same method as the first layered object 2, and has the same shape as the first layered object 2. Therefore, a description of the configuration of the fifth layered object 10 will be omitted. Hereinafter, the portion of the fifth layered object 10 corresponding to the first plate portion 12 will be referred to as a fifth plate portion 79, the portion of the fifth layered object 10 corresponding to the first joint portion 20 will be referred to as a fifth joint portion 65, and the space of the fifth layered object 10 corresponding to the first space 21 will be referred to as a fifth space 88 (not shown). In other words, the fifth plate portion 79 has the same shape as the first plate portion 12, and has a zigzag shape when viewed from the up-down direction D1. The fifth joint portion 65 is integrally formed at one end portion 87 on one side in the longitudinal direction D2 of the fifth plate portion 79. The fifth joint portion 65 has the same shape as the first joint portion 22, and has a circular ring shape when viewed from above.

[0037] Incidentally, when the third layered object 6 includes one end face of the wall 1A in the length direction D2, the opposite-side third joint 63 may extend downward to the height position of the lower surface of the third joint 62, or may not be formed. Similarly, when the fifth layered object 10 includes the other end face of the wall 1A in the length direction D2, the portion 64 of the fifth layered object 10 corresponding to the other-end-side first joint 22 may extend upward to the height position of the upper surface of the fifth joint 65, or may not be formed.

[0038] The fourth layered object 8 and the sixth layered object 11 will now be described. The fourth layered object 8 and the sixth layered object 11 are each formed by the layered object building machine 100 using the same method as the second layered object 4, and have the same shape as the second layered object 4. Therefore, a description of the configuration of the fourth layered object 8 and the sixth layered object 11 will be omitted. Hereinafter, the portion of the fourth layered object 8 corresponding to the second plate portion 24 will be referred to as the fourth plate portion 66, the portion of the fourth layered object 8 corresponding to the other-end-side second joint portion 34 will be referred to as the fourth joint portion 67, the portion of the fourth layered object 8 corresponding to the second joint portion 32 will be referred to as the opposite-side fourth joint portion 68, and the space of the fourth joint portion 67 corresponding to the second space 33 will be referred to as the fourth space 72. The portion of the sixth layered object 11 corresponding to the second plate portion 24 is referred to as a sixth plate portion 89, and the space of the sixth layered object 11 corresponding to the second space 33 is referred to as a sixth space 91 (not shown).

[0039] Incidentally, when the fourth layered object 8 includes one end face of the wall 1A on one side in the longitudinal direction D2, the opposite-side fourth joint 68 may extend upward to the height position of the upper surface of the fourth joint 67, or may not be formed. Similarly, when the sixth layered object 11 includes the other end face of the wall 1A on the other side in the longitudinal direction D2, a portion 69 of the sixth layered object 11 corresponding to the other-end-side second joint 34 may extend downward to the height position of the lower surface of the portion of the sixth layered object 11 (sixth joint 70) corresponding to the second joint 32, or may not be formed.

[0040] 2, the third layered object 6 are arranged adjacent to each other on one side of the first layered object 2 in the length direction D2. The first joint 20 is arranged on the third joint 62. The fourth layered object 8 are arranged adjacent to each other on one side of the second layered object 4 in the length direction D2. Furthermore, the fourth layered object 8 is arranged on the third layered object 6. The third joint 62, the first joint 20, the second joint 32, and the fourth joint 67 are arranged in this order from bottom to top in the up-down direction D1.

[0041] The rod member 90 has a rod shape and is, for example, a rebar. As shown in Fig. 2, the rod member 90 passes through both the first space 21 of the first joint 20 and the third space 71 of the third joint 62. The rod member 90 also passes through the second space 33 of the second joint 32 and the fourth space 72 of the fourth joint 67. In one embodiment, the third layered object 6 and the fourth layered object 8 are arranged at an angle with respect to the longitudinal direction D2 by rotating the third plate portion 61 and the fourth plate portion 66 around the rod member 90 as a central axis.

[0042] In one embodiment, as illustrated in FIG. 2 , the fifth layered object 10 is disposed adjacent to the other side of the first layered object 2 in the length direction D2. The fifth joint 65 is joined to the other end side first joint 22 while being displaced in the up-down direction D1. Specifically, the fifth joint 65 is disposed on the other end side first joint 22. The sixth layered object 11 is disposed adjacent to the other side of the second layered object 4 in the length direction D2. Furthermore, the sixth layered object 11 is disposed on the fifth layered object 10. The other end side first joint 22, the fifth joint 65, the sixth joint 70, and the other end side second joint 34 are disposed in this order from bottom to top in the up-down direction D1.

[0043] 2 , the wall 1A further includes a second rod member 92 that passes through the other-end-side first space 23 of the other-end-side first joint 22, the fifth space 88 of the fifth joint 65, the sixth space 91 of the sixth layered object 11 corresponding to the second space 33, and the other-end-side second space 35 of the other-end-side second joint 34. The second rod member 92 has a rod shape and is, for example, a rebar. The fifth layered object 10 and the sixth layered object 11 are arranged in a straight line with the first layered object 2 and the second layered object 4 so as to be parallel to the longitudinal direction D2.

[0044] 2, the wall 1A further includes a filling portion 96 formed by filling the first space 21, the second space 33, the third space 71, and the fourth space 72 with the filler X. Similarly, the wall 1A further includes a second filling portion 98 formed by filling the other-end-side first space 23, the fifth space 88, the sixth space 91, and the other-end-side second space 35 with the filler X.

[0045] In one embodiment, as illustrated in FIG. 2 , the second layered object 4 is disposed on the first layered object 2 such that the second other-side protrusion 28 overlaps with the first one-side protrusion 14 in the length direction D2, and the second one-side protrusion 26 overlaps with the first other-side protrusion 16 in the length direction D2. With this arrangement, the first one-side protrusion 14 and the second other-side protrusion 28 are adjacent to each other in the up-down direction D1. When viewed from the up-down direction D1, the first one-side protrusion 14 and the second other-side protrusion 28 surround each other, thereby forming a first gap 40. Similarly, the first other-side protrusion 16 and the second one-side protrusion 26 are adjacent to each other in the up-down direction D1. A second gap 42 is formed by the first other-side protrusion 16 and the second one-side protrusion 26 surrounding each other.

[0046] In some embodiments, the second layered object 4 has the same shape as the first layered object 2. In this case, the second layered object 4 included in the wall 1A is the first layered object 2 turned upside down. In other words, a plurality of first layered objects 2 are alternately stacked upside down. This configuration can reduce the manufacturing cost of the wall 1A.

[0047] (Actions and Effects) The following describes the functions and effects of the wall 1A according to one embodiment. According to this embodiment, the third plate portion 61 and the fourth plate portion 66 can be rotated around the rod member 90 as a central axis. This allows the third layered object 6 and the fourth layered object 8 to be arranged at an angle or in a straight line relative to the first layered object 2 and the second layered object 4, thereby increasing the variety of shapes of the wall 1A. Furthermore, because the rod member 90 passes through the first space 21 to the fourth space 72, the first layered object 2 to the fourth layered object 8 can be integrated.

[0048] According to one embodiment, the wall 1A includes the filling portion 96, which allows the first layered object 2 to the fourth layered object 8 to be more firmly integrated, thereby improving the strength of the wall 1A.

[0049] When using the additive manufacturing machine 100 to manufacture an additively manufactured object that includes a bent portion (e.g., a portion bent at a right angle), the amount of material discharged toward the bent portion increases when the direction of movement of the nozzle 102 is changed, which may result in manufacturing an additively manufactured object with a shape that differs significantly from the intended shape. According to one embodiment, the arc portion 29, the other-end-side arc portion 31, the second arc portion 36, the second other-end-side arc portion 37, the third arc portion 85, and the opposite-side arc portion 86 each have an arc shape, allowing the additive manufacturing machine 100 to smoothly layer the cementitious material M. This makes it possible to manufacture an additively manufactured object with a shape that is close to the intended shape.

[0050] Note that the present disclosure does not limit the shapes of the first joint 20, the other-end-side first joint 22, the second joint 32, the other-end-side second joint 34, the third joint 62, and the opposite-side third joint 63 to annular shapes. FIG. 9 is a diagram showing the configuration of a first joint 20 according to another embodiment, viewed from above. In the example shown in FIG. 9, the first joint 20 has a square ring shape to define the first space 21 when viewed from above, and the four corners are rounded. FIG. 10 is a diagram showing the configuration of a first joint 20 according to yet another embodiment, viewed from above. In the example shown in FIG. 10, the first joint 20 has an arc shape, specifically a C-shape, to define the first space 21 when viewed from above. Similarly, each of the other end side first joint 22, the second joint 32, the other end side second joint 34, the third joint 62, and the opposite side third joint 63 may have a square ring shape or a C shape.

[0051] According to one embodiment, the first plate portion 12, the second plate portion 24, the third plate portion 61, the fourth plate portion 66, the fifth plate portion 79, and the sixth plate portion 89 each have a zigzag shape, so that the wall 1A is configured to be wide in the width direction D3. Therefore, compared to a flat wall, the wall 1A has a higher resistance to a load in the width direction D3, and can be prevented from collapsing toward the ground or floor.

[0052] It should be noted that the present disclosure is not limited to each of the first plate portion 12 to the sixth plate portion 89 having a zigzag shape. At least one of the first plate portion 12 to the sixth plate portion 89 may have a zigzag shape. Each of the first plate portion 12 to the sixth plate portion 89 may be flat.

[0053] According to one embodiment, the fifth plate portion 79 and the sixth plate portion 89 can be rotated around the second rod member 92 as a central axis. Therefore, similar to the third layered object 6 and the fourth layered object 8, the fifth layered object 10 and the sixth layered object 11 can be arranged at an angle or in a straight line relative to the first layered object 2 and the second layered object 4, thereby increasing the variety of shapes of the wall 1A. Furthermore, because the second rod member 92 passes through all of the other-end-side first space 23, the fifth space 88, the sixth space 91, and the other-end-side second space 35, the first layered object 2, the second layered object 4, the fifth layered object 10, and the sixth layered object 11 can be integrated.

[0054] According to one embodiment, the first joint of the first layered object and the first joint on the other end side are offset from each other in the vertical direction, so that the two first layered objects 2 can be arranged next to each other along the longitudinal direction D2. In other words, the third layered object 6 and the fifth layered object 10 have the same or similar shape as the first layered object 2. This reduces the number of steps required to form the wall 1A.

[0055] The present disclosure does not limit the shape of the layered object included in the wall 1A to the shape of the first layered object 2 or the shape of the second layered object 4. Fig. 11 is a perspective view schematically showing the configuration of the second layered object 4 according to a first modified example. Fig. 12 is a perspective view schematically showing the configuration of the second layered object 4 according to a second modified example. Fig. 13 is a perspective view schematically showing the configuration of the second layered object 4 according to a third modified example. The first layered object 2 may have the shape shown in Figs. 11 to 13.

[0056] 11, the second joint portion 32 is located higher than the other-end-side second joint portion 34. The other-end-side second joint portion 34 has a lower surface 34b that is continuous with the lower surface 24b of the second plate portion 24. The lower surface 32b of the second joint portion 32 and the upper surface 34a of the other-end-side second joint portion 34 are at the same or almost the same position in the up-down direction D1.

[0057] 12, the lower surface 32b of the second joint 32 is continuous with the lower surface 24b of the second plate portion 24. The lower surface 34b of the other-end-side second joint 34 is continuous with the lower surface 24b of the second plate portion 24. The upper surface 32a of the second joint 32 and the upper surface 34a of the other-end-side second joint 34 are positioned at the same or almost the same level in the up-down direction D1.

[0058] 13, the second joint portion 32 and the other-end-side second joint portion 34 are positioned so as to overlap each other in the vertical direction D1 between the upper surface 24a and the lower surface 24b of the second plate portion 24. The lower surface 32b of the second joint portion 32 and the lower surface 34b of the other-end-side second joint portion 34 are positioned at the same or almost the same position as each other in the vertical direction D1.
