Summary of the Invention

Problems to be Solved by the Invention

[0005] In the additive manufacturing process of Patent Document 1 above, since it is necessary to arrange a wire mesh-shaped reinforcing material before injecting the matrix material, it is difficult to ensure the accuracy of the reinforcement arrangement.

[0006] In consideration of the above facts, the present disclosure provides a method for manufacturing a structural member, a structural member, and a building that can easily ensure the accuracy of the reinforcement arrangement.

Means for Solving the Problems

[0007] The manufacturing method of the structural member of the first aspect includes a step of laminating wet materials and installing a plurality of guide ribs protruding to the outside of the wet materials for each predetermined number of layers of the wet materials to form an outer frame member, a step of fixing reinforcing bars along the outer frame member to the guide ribs for steel bar placement, a step of oppositely arranging the outer frame members before or after placing the reinforcing bars, and a step of filling a filler between the oppositely arranged outer frame members.

[0008] In the manufacturing method of the structural member of the first aspect, a plurality of guide ribs are installed for each predetermined number of layers in the outer frame member formed by laminating wet materials. That is, the guide ribs are installed for each predetermined height.

[0009] Thereby, the reinforcing bars fixed to the guide ribs can also be placed for each predetermined height. Therefore, the accuracy of steel bar placement of the structural member can be increased.

[0010] In addition, since the reinforcing bars are fixed to the guide ribs, a disposable formwork member in which the wet materials, the guide ribs, and the reinforcing bars are integrated can be formed. By producing this disposable formwork member at a factory or on-site, oppositely arranging it at the installation location, and filling the filler, the structural member can be manufactured, so that the manufacturing work at the installation location can be reduced.

[0011] The manufacturing method of the structural member of the second aspect is the manufacturing method of the structural member described in the first aspect, in which the outer frame members are oppositely arranged after placing the reinforcing bars.

[0012] In the manufacturing method of the structural member of the second aspect, the outer frame members are oppositely arranged after placing the reinforcing bars. Therefore, even if the interval between the outer frame members is narrow, steel bar placement can be performed. Thereby, even when forming a wall body as the structural member, it is easy to place the reinforcing bars as wall reinforcement.

[0013] The manufacturing method of the structural member of the third aspect is the manufacturing method of the structural member described in the first aspect, in which the reinforcing bars are placed after oppositely arranging the outer frame members.

[0014] In the manufacturing method of the structural member according to the third aspect, after arranging the outer frame members opposite to each other, reinforcing bars are arranged. Therefore, it is possible to arrange the reinforcing bars straddling between the oppositely arranged outer frame members. As a result, for example, even when forming a beam or a column as a structural member, it is possible to arrange the web bars of the beam straddling between the outer frame members and the hoop bars of the column.

[0015] The structural member according to the fourth aspect includes an outer frame member including wet materials laminated over a plurality of layers and a plurality of guide bars provided for each predetermined number of layers of the wet materials and protruding to the outside of the wet materials, reinforcing bars fixed to the guide bars and arranged along the outer frame member, and a filler filled between the oppositely arranged outer frame members.

[0016] In the structural member according to the fourth aspect, a plurality of guide bars are arranged for each predetermined number of layers of the outer frame member formed by laminating wet materials. That is, the guide bars are installed at each predetermined height. As a result, the reinforcing bars fixed to the guide bars are also arranged at each predetermined height. Therefore, the accuracy of arranging the reinforcing bars of the structural member is high.

[0017] Further, since the reinforcing bars are fixed to the guide bars, it is possible to form a disposable formwork member in which the wet materials, the guide bars, and the reinforcing bars are integrated. By producing this disposable formwork member at a factory or on-site, arranging them opposite to each other at the installation location, and filling them with a filler, a structural member can be manufactured, so that the manufacturing work at the installation location can be reduced.

[0018] The building according to the fifth aspect has a floor slab, a room unit having an outer frame member fixed to the floor slab and including wet materials laminated over a plurality of layers and guide bars provided for each predetermined number of layers of the wet materials and protruding to the outside of the wet materials, reinforcing bars fixed to the guide bars and arranged along the outer frame member, and a filler filled between the respective outer frame members in the adjacent room units.

[0019] In the building of the fifth aspect, a plurality of guide bars are arranged for each predetermined number of layers of the outer frame members formed by laminating wet materials. That is, the guide bars are installed at each predetermined height. As a result, the reinforcing bars fixed to the guide bars are also arranged at each predetermined height. Therefore, the accuracy of arranging the reinforcing bars of the structural members is high.

[0020] In addition, since the reinforcing bars are fixed to the guide bars, a disposable formwork member in which the wet material, the guide bars, and the arranged reinforcing bars are integrated can be formed. Further, since the outer frame member is fixed to the floor slab, a room unit in which the floor slab and the disposable formwork member are integrated can be formed. Since the building can be constructed by producing this room unit at a factory or on-site, arranging the room units opposite to each other at the installation location of the room unit and filling with a filler, the construction work at the installation location can be reduced.

Advantages of the Invention

[0021] According to the present disclosure, it is easy to ensure the accuracy of arranging the reinforcing bars.

Embodiments for Carrying Out the Invention

[0023] Hereinafter, a method for manufacturing a structural member, the structural member, and a building according to an embodiment of the present disclosure will be described with reference to the drawings. Components denoted by the same reference numerals in each drawing mean the same components. However, unless otherwise specified in the specification, each component is not limited to one, and a plurality of them may exist.

[0024] In addition, descriptions of overlapping configurations and reference numerals in each drawing may be omitted. Note that the present disclosure is not limited to the following embodiments, and appropriate changes such as omitting configurations or replacing them with different configurations can be made within the scope of the object of the present disclosure and implemented.

[0025] In each figure, the directions indicated by arrows X and Y are along the horizontal plane and are perpendicular to each other. Also, the direction indicated by arrow Z is along the vertical direction (up and down direction). In each figure, the directions indicated by arrows X, Y, and Z are assumed to coincide with each other.

[0026] <Schematic Configuration of Structural Member> The structural members according to the embodiments of the present disclosure are, as an example, the wall body 10 shown in FIG. 1A and the beam 12 shown in FIG. 1B. The wall body 10 is formed using an outer frame member 20, reinforcing bars 30 (see, for example, FIG. 4A), and a filler 40. Similarly, the beam 12 is formed using an outer frame member 50, reinforcing bars 60 (see, for example, FIG. 7A), and the filler 40. Note that the structural members of the present disclosure include, in addition to the wall body 10 and the beam 12, columns, walls, composites of columns and walls, composites of columns and beams, and the like, as will be described later.

[0027] In this specification, first, the "manufacturing method" of these structural members will be described together with the configuration of the structural members, and then the construction method of the "building" formed using this structural member will be described.

[0028] <Manufacturing Method of Structural Member (Wall Body)> FIGS. 2A to 5B show the manufacturing method of the wall body 10 as a structural member.

[0029] (Formation of Outer Frame Member) To manufacture the wall body 10, first, the outer frame member 20 shown in FIGS. 2A and 2B is formed. The outer frame member 20 is a member that serves as a disposable mold for the filler 40 described later and is configured to include a wet material 22 and guide bars 24.

[0030] The wet material 22 is, for example, mortar, which is discharged in a paste form from the nozzle 100 of a shaping device (such as a 3D printer, etc.), and is formed into a long-layered shape as the nozzle 100 is moved in the lateral direction. By laminating these layers in the vertical direction, a plate-shaped disposable mold made of the wet material 22 is formed.

[0031] The guide bars 24 are reinforcing bars provided for each predetermined number of layers of the wet material 22 and protruding to the outside of the wet material 22. Here, the "outside" refers to the direction intersecting with the longitudinal direction of the wet material 22. As shown in FIG. 2C, the guide bars 24 are installed on the upper surface of the stacked wet materials 22 every time the wet materials 22 are stacked in a predetermined number of layers (N layers). Further, a plurality of guide bars 24 are arranged at a predetermined interval (interval M) along the longitudinal direction (X direction) of the wet material 22.

[0032] Thereby, the guide bars 24 are arranged every "thickness of the N layers of the wet material 22" in the vertical direction (Z direction). Also, the guide bars 24 are arranged every "interval M" in the lateral direction (X direction). Note that the vertical direction and the lateral direction are directions along the in-plane direction of the wall member 10. Through the above steps, the outer frame member 20 is formed.

[0033] (Reinforcement arrangement) Next, as shown in FIGS. 3A and 3B, horizontal bars 32 along the outer frame member 20 are fixed to the guide bars 24 for reinforcement arrangement. Specifically, the horizontal bars 32 are placed on and fixed to a plurality of guide bars 24 arranged at the same height. Thereby, the horizontal bars 32 are arranged every "thickness of the N layers (see FIG. 2(C)) of the wet material 22" in the vertical direction (Z direction).

[0034] Note that a gap may or may not be formed between the horizontal bars 32 and the outer frame member 20. When forming a gap, even if there is a missing portion in the wet material 22 of the outer frame member 20, the covering thickness can be ensured. On the other hand, when the wet material 22 can be constructed densely without defects, the covering thickness can be ensured by the thickness of the wet material 22 even without forming a gap.

[0035] Next, as shown in FIGS. 4A and 4B, vertical bars 34 along the outer frame member 20 are fixed to the guide bars 24 for reinforcement arrangement. Specifically, the vertical bars 34 are fixed along a plurality of guide bars 24 arranged at the same position in the lateral direction. Thereby, the vertical bars 34 are arranged every interval M (see FIG. 2C) in the lateral direction (X direction).

[0036] Note that the vertical bars 34 may be fixed to the horizontal bars 32. Also, the construction order of the vertical bars 34 and the horizontal bars 32 may be swapped. In this specification, the horizontal bars 32 and the vertical bars 34 may be collectively referred to as the reinforcing bars 30. Through the above steps, the reinforcing bars 30 are fixed to the outer frame member 20, and the disposable formwork member S1 is formed.

[0037] (Formation of the wall) Next, as shown in FIG. 5A, the disposable formwork members S1 with the reinforcing bars 30 fixed to the outer frame member 20 are arranged opposite to each other. "Arranged opposite to each other" means arranging them facing each other on the side of the outer frame member 20 where the reinforcing bars 30 are fixed.

[0038] Then, as shown in FIG. 5B, a filler 40 is filled between the oppositely arranged outer frame members 20. The filler 40 is, for example, concrete. For the portions where the outer frame members 20 are not arranged, that is, at the ends in the longitudinal direction (X direction) of the outer frame members 20, a formwork is installed as necessary to prevent the leakage of the filler 40.

[0039] Through the above steps, the wall 10 using the outer frame member 20 as a disposable formwork is formed. As shown in FIG. 5A, this wall 10 includes a wet material 22 laminated over a plurality of layers, and a plurality of guide bars 24 provided for each predetermined number of layers (N layers: see FIG. 2C) of the wet material 22 and protruding to the outside of the wet material 22, and an outer frame member 20.

[0040] Also, the wall 10 is reinforced by being fixed to the guide bars 24 and includes reinforcing bars 30 (horizontal bars 32 and vertical bars 34) along the outer frame member 20. Further, as shown in FIG. 5B, the wall 10 includes a filler 40 filled between the oppositely arranged outer frame members 20.

[0041] (Construction site) When forming the wall 10, as an example, the above "formation of the outer frame member" and "reinforcement arrangement" are carried out at the factory. That is, the disposable formwork member S1 shown in FIGS. 4A and 4B is manufactured at the factory. Then, the disposable formwork member S1 manufactured at the factory is transported to the construction site of a building or the like, and the above "formation of the wall" is carried out.

[0042] Also, as another example, the above-described "formation of the outer frame member" is carried out in a factory. Then, the outer frame member 20 shown in FIGS. 2A and 2B manufactured in the factory is carried into a construction site such as a building, and the above-described "reinforcement bar arrangement" is carried out to form the formwork member S1. The formwork member S1 may be formed not only at the location where the wall body 10 is constructed but also at a work yard or the like at the construction site. Thereafter, the above-described "formation of the wall body" is carried out.

[0043] <Manufacturing method of a structural member (beam)> In FIGS. 6A to 7C, a manufacturing method of a beam 12 as a structural member is shown.

[0044] (Formation of the outer frame member) To manufacture the beam 12, first, an outer frame member 50 shown in FIGS. 6A and 6B is formed. The outer frame member 50 is a member that serves as a disposable mold for the filler 40, and is configured to include a wet material 52 and guide bars 54, similar to the above-described outer frame member 20.

[0045] The wet material 52 is, for example, mortar, similar to the above-described wet material 22, and is discharged in a paste form from the nozzle of a shaping device. Then, as the nozzle 100 is moved in the lateral direction, as shown in FIG. 6B, it is formed in an "L shape" in plan view. Also, as shown in FIG. 6A, it is formed in layers. By laminating these layers in the vertical direction, a disposable mold in an "L shape" in plan view made of the wet material 52 is formed.

[0046] Note that the "L shape" is a shape formed by one side of a quadrilateral and another side adjacent to this side. In the present embodiment, one side is long and the other side is short. In the following description, these sides of the wet material 52 are referred to as a long side 52A and a short side 52B.

[0047] The guide bars 54 are installed on the upper part of the laminated wet material 52 every time a predetermined number of layers of the wet material 52 are laminated, similar to the above-described guide bars 24. Also, a plurality of guide bars 54 are arranged along the extending directions (X direction and Y direction) of the wet material 52.

[0048] Note that the intervals and number of the guide bars 54 in the extending direction of the wet material 52 are not particularly limited. However, from the viewpoint of facilitating the positioning of the web bars 62 (see FIGS. 7A and 7B) described later, it is preferable to provide two or more on the long side 52A and one or more on the short side 52B.

[0049] Further, from the viewpoint of facilitating the positioning of the beam main bars 64 described later, it is more preferable that the guide bars 54 are provided at the locations where the beam main bars 64 are installed.

[0050] Next, as shown in FIG. 6C, the outer frame members 50 are arranged opposite to each other. "Arranged opposite to each other" means arranging the outer frame members 50 with the sides where the guide bars 54 protrude facing each other. Also, in the present embodiment, the two outer frame members 50 are arranged with the end faces of their respective short sides 52B abutting against each other. Thereby, the two outer frame members 50 are arranged in a "U-shaped" cross-sectional shape.

[0051] (Reinforcement bar arrangement) Next, as shown in FIGS. 7A and 7B, the web bars 62 along the outer frame members 50 are fixed to the guide bars 54 for bar arrangement. In this figure, the outer frame members 50 are replaced from the state shown in FIG. 6 so that the stacking direction of the wet material 52 is along the horizontal direction. That is, the outer frame members 50 are arranged in the posture of being used as the disposable formwork of the beam 12 shown in FIG. 1B.

[0052] The web bars 62 are fixed to a plurality of guide bars 54 arranged at the same position in the horizontal direction (X direction). The web bars 62 are formed in a rectangular frame shape as shown in FIG. 7B and are arranged across the oppositely arranged outer frame members 50. Also, the web bars 62 are fixed to the guide bars 54 in each of the outer frame members 50.

[0053] Thereby, the web bars 62 are arranged at predetermined intervals in the horizontal direction (X direction). Note that, similar to the horizontal bars 32 described above, a gap may or may not be formed between the web bars 62 and the outer frame members 50.

[0054] Next, the main beam reinforcement 64 is fixed to the corner of the stirrup 62. The main beam reinforcement 64 is arranged along the lamination direction of the wet material 52, that is, the extending direction of the beam 12 (see FIG. 1B). Further, the main beam reinforcement 64 is arranged inside the stirrup 62. Note that the main beam reinforcement 64 may be fixed to the guide reinforcement 54. Furthermore, the main beam reinforcement 64 is installed at least at the four corners of the stirrup 62, but the number and position can be appropriately increased or decreased.

[0055] In this specification, the stirrup 62 and the main beam reinforcement 64 may be collectively referred to as the reinforcement 60. Through the above steps, the disposable formwork member S2 with the reinforcement 60 fixed to the outer frame member 50 is formed.

[0056] (Formation of the beam) Next, as shown in FIG. 7C, the filling material 40 is filled between the oppositely arranged outer frame members 50. For the portions where the outer frame members 50 are not arranged, that is, the ends in the longitudinal direction (X direction) of the outer frame members 50, a formwork is installed as necessary to prevent the leakage of the filling material 40.

[0057] Through the above steps, the beam 12 using the outer frame member 50 as a disposable formwork is formed. As shown in FIG. 7A, this beam 12 includes the wet material 52 laminated in multiple layers and the outer frame member 50 provided with a plurality of guide reinforcements 54 that are provided for each predetermined number of layers of the wet material 52 and protrude to the outside of the wet material 52.

[0058] Further, the beam 12 is arranged with reinforcement fixed to the guide reinforcement 54 and includes the reinforcement 60 (stirrup 62 and main beam reinforcement 64) along the outer frame member 50. Furthermore, as shown in FIG. 7C, the beam 12 includes the filling material 40 filled between the oppositely arranged outer frame members 50.

[0059] (Construction site) When forming the beam 12, as an example, the above-mentioned "formation of the outer frame member" and "arrangement of the reinforcement" are carried out at the factory. That is, the disposable formwork member S2 shown in FIG. 7B is manufactured at the factory. Then, the disposable formwork member S2 manufactured at the factory is transported to the construction site of a building or the like, and the above-mentioned "formation of the beam" is carried out.

[0060] Also, as another example, the above-mentioned "formation of the outer frame member" is carried out in a factory. Then, the outer frame member 50 shown in Fig. 6B manufactured in the factory is carried into a construction site such as a building and arranged opposite to each other, and the above-mentioned "reinforcement arrangement of steel bars" is carried out to form the formwork member S2 shown in Fig. 7B. The formwork member S2 may be formed not only at the location where the beam 12 is constructed but also at a work yard or the like at the construction site. Then, the above-mentioned "formation of the wall body" is carried out.

[0061] <Manufacturing method of structural member (column)> Using the above-mentioned outer frame member 50, steel bars 60 and filling material 40, a column can also be manufactured. To manufacture a column, the steel bars 60 shown in Figs. 7A and 7B are arranged with respect to the outer frame member 50 in the postures shown in Figs. 6A and 6B. At this time, the web bars 62 are arranged as hoop bars, and the main beam bars 64 are arranged as main column bars.

[0062] When filling the filling material 40, a formwork is installed at the end of the long side 52A of the wet material 52. Then, using the outer frame member 50 and the formwork, the inside of the outer frame member 50 is closed. By filling the filling material 40 in this state, a column can be manufactured.

[0063] Also, when manufacturing a column, the wet material may be formed in a "U shape (angle shape)" in plan view, and the outer frame members may be arranged opposite to each other so as to form a rectangular shape.

[0064] <Building construction method> The structural member according to the embodiment of the present disclosure can be used when constructing a building 90. The building 90 can be constructed, for example, by manufacturing the room unit 70 shown in Figs. 8A and 8B in a factory and assembling this room unit 70 on site.

[0065] (Manufacturing method of room unit) The room unit 70 includes a floor slab 72 and the above-mentioned outer frame member 20. The floor slab 72 is manufactured using concrete or the like in a factory. As shown in Fig. 8B, steel bars 72A to be embedded in the filling material 40 protrude from the end face of the floor slab 72.

[0066] The outer frame member 20 is constructed by laminating the wet material 22 while arranging the guide bars 24 at the upper part and the outer peripheral part of the floor slab 72.

[0067] As shown in FIG. 8A, the outer frame member 20 in this example is shaped with a bent portion along the outer peripheral part of the floor slab 72. Thus, the outer frame member 20 (the outer frame member forming the wall body 10) according to the embodiment of the present disclosure may be provided with a bent portion. Also, it may be formed in a curved shape in plan view.

[0068] Further, a part of the outer frame member 20 constitutes a wall body, and another part constitutes a column. Thus, the outer frame member 20 according to the embodiment of the present disclosure does not necessarily have to constitute only the wall body, and may be configured as a composite of the wall body and the column.

[0069] In this embodiment, at the factory, reinforcing bars 30 (horizontal bars 32 and vertical bars 34) are fixed to the outer frame member 20, and the disposable formwork member S1 is formed. These reinforcing bars 30 may be fixed to the outer frame member 20 at the construction site of the building.

[0070] In the room unit 70, at the time of factory shipment, in addition to the reinforcing bars 30, the miscellaneous wall 80, the entrance door 82, and the sweep-out window 84 are fixed. In the room unit 70, various other members such as partition walls, equipment such as kitchens and toilets, and floor finishing materials can be fixed as appropriate. Also, it is not necessary to fix the miscellaneous wall 80, the entrance door 82, and the sweep-out window 84 to the room unit 70.

[0071] (Method of constructing a building) In order to construct the building 90 with the room units 70, as shown by the dashed line in FIG. 8A, a plurality of room units 70 are arranged side by side. Thereby, the outer frame members 20 in each room unit 70 are arranged opposite to each other. At this time, although not shown in the drawing, the reinforcing bars 30 are also fixed to the outer frame members 20 of the room units 70 shown by the dashed line in FIG. 8A.

[0072] When arranging the room units 70 side by side, formwork 86 is arranged after arranging wall reinforcing bars and column reinforcing bars in the portions where the outer frame members 20 do not face each other.

[0073] Finally, the wall body 10 (see FIG. 1A, etc.) is constructed by filling a filler 40 (see FIG. 1A, etc.) between the opposing outer frame members 20 or between the outer frame member 20 and the formwork 86, and a building 90 in which the room units 70 are connected to each other is constructed. The room units 70 are connected in the horizontal direction, but they may be further stacked in the vertical direction.

[0074] <Operation and Effect> In the method for manufacturing a structural member according to the embodiment of the present disclosure, as shown in FIGS. 2A and 2B, a plurality of guide bars 24 are installed in the outer frame member 20 formed by laminating wet materials 22 at every predetermined number of layers. That is, the guide bars 24 are installed at every predetermined height (thickness of one layer of wet material × number of layers N).

[0075] Thereby, as shown in FIGS. 3A and 3B, the horizontal bars 32 fixed to the guide bars 24 can also be arranged at every predetermined height. Therefore, the reinforcement accuracy of the wall body 10 (see FIG. 1A) as a structural member can be increased.

[0076] Further, as shown in FIGS. 4A and 4B, since the reinforcing bars 30 (horizontal bars 32 and vertical bars 34) are fixed to the guide bars 24, a disposable formwork member S1 in which the wet material 22, the guide bars 24, and the reinforcing bars 30 are integrated can be formed. If this disposable formwork member S1 is produced at a factory or on-site and arranged opposite to each other at the installation location and filled with the filler 40 as shown in FIGS. 5A and 5B, the wall body 10 as a structural member can be manufactured, and thus the manufacturing work at the installation location can be reduced.

[0077] Also, in the method for manufacturing the wall body 10 as a structural member according to the embodiment of the present disclosure, as shown in FIGS. 4A, 4B, and 5A, after arranging the reinforcing bars 30, the outer frame members 20 are arranged opposite to each other. Therefore, even if the interval between the outer frame members 20 is narrow, in other words, regardless of the size of the interval between the outer frame members 20, the reinforcing bars 30 can be arranged. Thereby, the arrangement of the reinforcing bars 30 as wall reinforcement is easy.

[0078] In addition, even when constructing the wall body 10 as a structural member, if the thickness of the wall body 10 is large, the reinforcing bars 30 may be fixed to the outer frame members 20 after the outer frame members 20 are arranged opposite to each other.

[0079] On the other hand, in the manufacturing method of the beam 12 as a structural member, as shown in FIGS. 6C, 7A, and 7B, after arranging the outer frame members 50 opposite to each other, the reinforcing bars 60 (web bars 62 and main beam bars 64) are arranged. Therefore, the web bars 62, which are the reinforcing bars straddling between the oppositely arranged outer frame members 50, can be arranged.

[0080] In addition, even when constructing the beam 12 or columns as structural members, the reinforcing bars 60 may be fixed to the outer frame members 50 before arranging the outer frame members 50 opposite to each other.

[0081] These effects can also be obtained in the building 90 constructed using the wall body 10. Further, in the building 90, as shown in FIGS. 8A and 8B, since the outer frame member 20 is fixed to the floor slab 72, a room unit 70 in which the floor slab 72 and the disposable form member S1 are integrated can be formed.

[0082] If this room unit 70 is produced at a factory or on-site, after arranging the reinforcing bars 30, and then arranged opposite to each other at the installation location of the room unit 70 and filled with the filling material 40 (see FIG. 1A, etc.), the building 90 can be constructed, so that the construction work at the installation location can be reduced.

[0083] In addition, in the building 90, although the outer frame member 20 is configured as a composite of the wall body and columns, the embodiments of the present disclosure are not limited thereto. The outer frame member of the present disclosure may be configured to form a composite of columns and beams, such as the outer frame member 92 shown in FIG. 9. Note that the guide bars in the outer frame member 92 are not shown.

[0084] To manufacture the outer frame member 92, as an example, the column portion 92A is laminated using a wet material in the same manner as the outer frame member 50 shown in FIGS. 6A and 6B. When forming the beam portion 92B, a backing plate and shoring are installed under the beam, and the wet material is laminated. After the wet material has hardened, the backing plate and shoring are removed.

[0085] By using such an outer frame member 92, the building 90 can be constructed as a column-beam structure (ramen structure).

[0086] As described above, the structural members of the present disclosure can be in various forms, such as the wall body 10, the beam 12, the column, the composite of the wall body and the column, the composite of the column and the beam, etc. Also, in the building 90 constructed using the structural members of the present disclosure, these various structural members can be used.
