Description

This disclosure relates to a method for manufacturing a structural member, a structural member, and a building.

The following patent document 1 describes an additive manufacturing process that includes the steps of placing a reinforcing material adjacent to a support structure and gradually injecting a matrix material into the support structure from a nozzle that is movable relative to the support structure to cover the reinforcing material.

In this additive manufacturing process, a reinforcement material in the form of a wire mesh is placed inside a support structure that forms the mold space before the matrix material is injected.

Special table 2018-535861 publication

In the additive manufacturing process of Patent Document 1, it is necessary to arrange the wire mesh-shaped reinforcing material before injecting the matrix material, making it difficult to ensure the accuracy of the reinforcing bar arrangement.

Taking the above facts into consideration, the present disclosure provides a manufacturing method for structural members, structural members, and buildings that make it easy to ensure reinforcement accuracy.

The manufacturing method of the first aspect of the structural member includes the steps of stacking wet materials and forming an outer frame member by installing a plurality of guide bars that protrude outward from the wet materials for every predetermined number of layers of the wet materials, fixing reinforcing bars along the outer frame member to the guide bars, arranging the outer frame members facing each other before or after arranging the reinforcing bars, and filling the space between the outer frame members that are arranged facing each other with a filler material.

In the first embodiment of the method for manufacturing a structural member, multiple guide bars are installed at every predetermined number of layers in the outer frame member formed by stacking wet materials. In other words, guide bars are installed at every predetermined height.

This allows the reinforcing bars fixed to the guide bars to be arranged at a specified height, thus improving the accuracy of reinforcing bars in structural members.

In addition, because the reinforcing bars are fixed to the guide bars, it is possible to form a throw-away formwork component in which the wet material, guide bars, and reinforcing bars are integrated. This throw-away formwork component can be produced in a factory or on-site, and then placed opposite each other at the installation site and filled with filler to manufacture the structural component, reducing the manufacturing work at the installation site.

The second aspect of the method for manufacturing a structural member is the method for manufacturing a structural member described in the first aspect, in which the reinforcing bars are arranged and then the outer frame members are placed opposite each other.

In the second embodiment of the manufacturing method for structural members, the reinforcing bars are placed in place, and then the outer frame members are placed facing each other. This allows for reinforcing bars to be placed even if the spacing between the outer frame members is narrow. This makes it easy to place reinforcing bars as wall reinforcement, even when forming a wall body as a structural member.

The third aspect of the method for manufacturing a structural member is the method for manufacturing a structural member described in the first aspect, in which the reinforcing bars are arranged after the outer frame members are placed opposite each other.

In the third embodiment of the manufacturing method for structural members, reinforcing bars are placed after the outer frame members are placed opposite each other. This allows reinforcing bars to be placed between the outer frame members placed opposite each other. This allows, for example, when beams and columns are formed as structural members, to place stirrups for beams that straddle the outer frame members, and hoop bars for columns.

The structural member of the fourth aspect comprises an outer frame member having a wet material laminated in multiple layers, a plurality of guide bars provided at intervals of a predetermined number of layers of the wet material and protruding outward from the wet material, reinforcing bars fixed to the guide bars and arranged along the outer frame member, and a filler material filled between the outer frame members arranged opposite each other.

In the fourth embodiment of the structural member, multiple guide bars are arranged for every predetermined number of layers of the outer frame member formed by stacking wet materials. In other words, the guide bars are installed at every predetermined height. As a result, the reinforcing bars fixed to the guide bars are also arranged at every predetermined height. This results in high reinforcement accuracy for the structural member.

In addition, because the reinforcing bars are fixed to the guide bars, it is possible to form a throw-away formwork component in which the wet material, guide bars, and reinforcing bars are integrated. This throw-away formwork component can be produced in a factory or on-site, and structural components can be manufactured by arranging them opposite each other at the installation site and filling them with filler, thereby reducing the manufacturing work at the installation site.

The building of the fifth aspect comprises a floor slab, a room unit having an outer frame member that is fixed to the floor slab and has wet materials stacked in multiple layers and guide bars that are provided for every predetermined number of layers of the wet materials and protrude outside the wet materials, reinforcing bars that are fixed to the guide bars and arranged along the outer frame member, and a filler material filled between the outer frame members of the room units that are adjacent to each other.

In the fifth aspect of the building, multiple guide bars are arranged for each predetermined number of layers of the outer frame member formed by stacking wet materials. In other words, 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. This results in high accuracy in the arrangement of reinforcement for the structural members.

In addition, because the reinforcing bars are fixed to the guide bars, it is possible to form a throw-away formwork member in which the wet material, guide bars, and reinforcement are integrated. In addition, because the outer frame members are fixed to the floor slab, it is possible to form a room unit in which the floor slab and the throw-away formwork member are integrated. These room units can be produced in a factory or on-site, and a building can be constructed by simply arranging them opposite each other at the installation site of the room units and filling them with filler, thereby reducing construction work at the installation site.

This disclosure makes it easier to ensure reinforcement accuracy.

<Outline of structural member configuration>
As an example, the structural member according to the embodiment of the present disclosure is a wall 10 shown in Fig. 1A and a beam 12 shown in Fig. 1B. The wall 10 is formed using an outer frame member 20, reinforcing bars 30 (see, for example, Fig. 4A), and a filler material 40. Similarly, the beam 12 is formed using an outer frame member 50, reinforcing bars 60 (see, for example, Fig. 7A), and a filler material 40. Note that the structural member according to the present disclosure includes, in addition to the wall 10 and the beam 12, a column, a complex of a wall and a column, and a complex of a column and a beam, etc., as described below.

In this specification, we first explain the "manufacturing method" of these structural members along with the configuration of the structural members, and then we explain the construction method of the "building" formed using these structural members.

<Method of manufacturing structural member (wall body)>
2A to 5B show a method for manufacturing a wall 10 as a structural member.

(Formation of outer frame member)
2A and 2B is formed. The outer frame member 20 is a member that serves as a throw-away formwork for the filling material 40 described later, and is configured to include a wet material 22 and guide bars 24.

The wet material 22 is, for example, mortar, and is discharged in a paste form from the nozzle 100 of a modeling device (e.g., a 3D printer, etc.), and is formed into long layers as the nozzle 100 is moved laterally. By stacking these layers vertically, a plate-shaped throwaway formwork is formed from the wet material 22.

The guide bars 24 are provided for every predetermined number of layers of the wet material 22, and are reinforcing bars that protrude to the outside of the wet material 22. Here, "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 top surface of the layered wet material 22 every time a predetermined number of layers (N layers) of the wet material 22 are stacked. Furthermore, multiple guide bars 24 are arranged at predetermined intervals (interval M) along the longitudinal direction (X direction) of the wet material 22.

As a result, the guide bars 24 are arranged in the vertical direction (Z direction) at every "thickness of N layers of wet material 22". The guide bars 24 are also arranged in the horizontal direction (X direction) at every "interval M". Note that the vertical and horizontal directions are directions along the in-plane direction of the wall body 10. Through the above process, the outer frame member 20 is formed.

(Reinforcing bar arrangement)
3A and 3B, the horizontal reinforcement bars 32 along the outer frame member 20 are fixed to the guide reinforcement bars 24. Specifically, the horizontal reinforcement bars 32 are placed on and fixed to a plurality of guide reinforcement bars 24 arranged at the same height. As a result, the horizontal reinforcement bars 32 are arranged in the vertical direction (Z direction) for each "thickness of the wet material 22 of the Nth layer (see FIG. 2C)".

In addition, a gap may or may not be formed between the horizontal reinforcement 32 and the outer frame member 20.
When gaps are formed, the covering thickness can be ensured even if there are defects in the wet material 22 of the outer frame member 20. On the other hand, when the wet material 22 can be applied densely without defects, the covering thickness can be ensured by the thickness of the wet material 22 even if gaps are not formed.

Next, as shown in Figures 4A and 4B, the vertical reinforcement 34 along the outer frame member 20 is fixed to the guide reinforcement 24. Specifically, the vertical reinforcement 34 is fixed along a plurality of guide reinforcement 24 arranged at the same position in the horizontal direction. As a result, the vertical reinforcement 34 is arranged at intervals M (see Figure 2C) in the horizontal direction (X direction).

The vertical bars 34 may be fixed to the horizontal bars 32. The construction order of the vertical bars 34 and the horizontal bars 32 may also be reversed. In this specification, the horizontal bars 32 and the vertical bars 34 may be collectively referred to as reinforcing bars 30. Through the above steps, the reinforcing bars 30 are fixed to the outer frame member 20, and the throw-away formwork member S1 is formed.

(Wall formation)
5A, the temporary formwork members S1 to which the reinforcing bars 30 are fixed are disposed facing the outer frame members 20. "Facing disposition" means that the sides of the outer frame members 20 to which the reinforcing bars 30 are fixed face each other.

Then, as shown in FIG. 5B, filler material 40 is filled between the opposing outer frame members 20. The filler material 40 is, for example, concrete. If necessary, formwork is installed in the portions where the outer frame members 20 are not placed, i.e., the ends of the outer frame members 20 in the longitudinal direction (X direction), to prevent leakage of the filler material 40.

Through the above steps, a wall 10 is formed using the outer frame member 20 as a throwaway formwork. As shown in FIG. 5A, the wall 10 includes an outer frame member 20 that includes multiple layers of laminated wet materials 22 and multiple guide bars 24 that are provided for each predetermined number of layers of the wet materials 22 (N layers: see FIG. 2C) and protrude outward from the wet materials 22.

The wall body 10 also includes reinforcing bars 30 (horizontal bars 32 and vertical bars 34) fixed to the guide bars 24 and arranged along the outer frame members 20. Furthermore, as shown in FIG. 5B, the wall body 10 includes a filler material 40 filled between the opposing outer frame members 20.

(Construction location)
When forming the wall body 10, as an example, the above-mentioned "forming of the outer frame members" and "arrangement of the reinforcing bars" are carried out in a factory. That is, the temporary formwork members S1 shown in Figures 4A and 4B are manufactured in a factory. The temporary formwork members S1 manufactured in the factory are then carried into a construction site such as a building, and the above-mentioned "forming of the wall body" is carried out.

As another example, the above-mentioned "forming of the outer frame member" is carried out in a factory. Then, the outer frame member 20 shown in Figures 2A and 2B manufactured in the factory is transported to a construction site such as a building, and the above-mentioned "reinforcing bar arrangement" is carried out to form the form member S1. The form member S1 may be formed not only at the location where the wall body 10 is constructed, but also in a work yard at the construction site. After that, the above-mentioned "forming of the wall body" is carried out.

<Manufacturing method of structural member (beam)>
6A to 7C show a method for manufacturing a beam 12 as a structural member.

(Formation of outer frame member)
6A and 6B is formed. The outer frame member 50 is a member that serves as a throw-away formwork for the filler material 40, similar to the outer frame member 20 described above, and is configured to include a wet material 52 and guide bars 54.

The wet material 52 is, for example, mortar, similar to the wet material 22 described above, and is discharged in a paste form from the nozzle of the molding device. Then, as the nozzle 100 is moved laterally, it is formed into an "L-shape" in plan view, as shown in FIG. 6B. It is also formed in layers, as shown in FIG. 6A. By stacking these layers vertically, a throwaway formwork that is "L-shaped" in plan view is formed from the wet material 52.

Note that an "L-shape" is a shape formed by one side of a rectangle and another side that is adjacent to the first side. In this 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 the long side 52A and the short side 52B.

The guide bars 54, like the guide bars 24 described above, are installed on top of the wet material 52 each time a predetermined number of layers of the wet material 52 are stacked. In addition, multiple guide bars 54 are arranged along the extension directions (X direction and Y direction) of the wet material 52.

The spacing and number of guide bars 54 in the extension direction of the wet material 52 are not particularly limited, but from the viewpoint of making it easier to position the stirrup bars 62 (see Figures 7A and 7B) described later, it is preferable to provide two or more guide bars on the long side 52A and one or more guide bars on the short side 52B.

In addition, from the viewpoint of making it easier to position the beam main reinforcement 64 described below, it is even more preferable to provide the guide reinforcement 54 at the location where the beam main reinforcement 64 will be installed.

Next, as shown in FIG. 6C, the outer frame members 50 are arranged facing each other. "Facing arrangement" means that the sides of the outer frame members 50 from which the guide grooves 54 protrude face each other. In this embodiment, the two outer frame members 50 are arranged with the end faces of their respective short sides 52B butted together. This results in the two outer frame members 50 being arranged so that their cross-sectional shape is "U-shaped."

(Reinforcing bar arrangement)
Next, as shown in Figures 7A and 7B, the stirrups 62 along the outer frame member 50 are fixed to the guide bars 54 for reinforcement. In these figures, the outer frame member 50 is displaced from the state shown in Figure 6 so that the lamination direction of the wet materials 52 is along the horizontal direction. That is, the outer frame member 50 is placed in a posture to be used as a throw-away formwork for the beam 12 shown in Figure 1B.

The stirrups 62 are fixed to multiple guide bars 54 arranged at the same position in the horizontal direction (X direction). As shown in FIG. 7B, the stirrups 62 are formed into a rectangular frame shape and are arranged across the outer frame members 50 arranged opposite each other. The stirrups 62 are also fixed to the guide bars 54 in each outer frame member 50.

As a result, the stirrups 62 are arranged at a predetermined interval in the horizontal direction (X direction). As with the horizontal bars 32 described above, a gap may or may not be formed between the stirrups 62 and the outer frame member 50.

Next, the beam main reinforcement bars 64 are fixed to the corners of the stirrup bars 62. The beam main reinforcement bars 64 are arranged along the stacking direction of the wet material 52, that is, along the extension direction of the beam 12 (see Figure 1B). The beam main reinforcement bars 64 are arranged on the inside of the stirrup bars 62. The beam main reinforcement bars 64 may also be fixed to the guide bars 54. Furthermore, the beam main reinforcement bars 64 are installed at least at the four corners of the stirrup bars 62, but the number and positions can be increased or decreased as appropriate.

In this specification, the stirrup bars 62 and the main beam bars 64 may be collectively referred to as reinforcing bars 60. Through the above steps, a temporary formwork member S2 is formed in which the reinforcing bars 60 are fixed to the outer frame member 50.

(Beam formation)
7C , the filler 40 is filled between the opposing outer frame members 50. In the portions where the outer frame members 50 are not disposed, i.e., the ends of the outer frame members 50 in the longitudinal direction (X direction), a formwork is installed as necessary to prevent leakage of the filler 40.

Through the above steps, a beam 12 is formed using the outer frame member 50 as a throwaway formwork. As shown in FIG. 7A, the beam 12 includes an outer frame member 50 that includes multiple layers of laminated wet material 52 and multiple guide bars 54 that are provided at intervals of a predetermined number of layers of the wet material 52 and protrude outward from the wet material 52.

The beam 12 is provided with reinforcing bars 60 (stirrups 62 and beam main reinforcements 64) fixed to the guide bars 54 and arranged along the outer frame members 50. Furthermore, as shown in FIG. 7C, the beam 12 is provided with filler material 40 filled between the opposing outer frame members 50.

(Construction location)
When forming the beam 12, as an example, the above-mentioned "forming the outer frame member" and "arrangement of the reinforcing bars" are performed in a factory. That is, the temporary formwork member S2 shown in Fig. 7B is manufactured in the factory. Then, the temporary formwork member S2 manufactured in the factory is carried into a construction site of a building or the like, and the above-mentioned "forming of the beam" is performed.

As another example, the above-mentioned "forming 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 transported to a construction site such as a building and arranged opposite each other, and the above-mentioned "reinforcing bar arrangement" is carried out to form the form member S2 shown in FIG. 7B. The form member S2 may be formed in the place where the beam 12 is constructed, or in a work yard at the construction site. After that, the above-mentioned "forming of the wall body" is carried out.

<Manufacturing method of structural members (pillars)>
A column can also be manufactured using the above-mentioned outer frame member 50, reinforcing bars 60, and filler material 40. To manufacture a column, reinforcing bars 60 shown in Figures 7A and 7B are arranged on the outer frame member 50 in the position shown in Figures 6A and 6B. At this time, stirrup reinforcements 62 are arranged as hoop reinforcements, and beam main reinforcements 64 are arranged as column main reinforcements.

When filling the filler 40, a formwork is placed at the end of the long side 52A of the wet material 52. Then, the outer frame member 50 and the formwork are used to close the inside of the outer frame member 50. By filling the filler 40 in this state, a column can be manufactured.

When manufacturing columns, the wet material can be formed into a U-shape (angle shape) in plan view, and the outer frame members can be arranged opposite each other to form a rectangular shape.

<How to build a building>
The structural member according to the embodiment of the present disclosure can be used in constructing a building 90. As an example, the building 90 can be constructed by manufacturing the room units 70 shown in Figures 8A and 8B in a factory and assembling the room units 70 on site.

(Room unit manufacturing method)
The room unit 70 includes a floor slab 72 and the above-mentioned outer frame member 20. The floor slab 72 is manufactured in a factory using concrete or the like. As shown in FIG. 8B , reinforcing bars 72A embedded in the filler material 40 protrude from the end face of the floor slab 72.

The outer frame member 20 is constructed by stacking wet materials 22 while placing guide bars 24 on the upper and outer periphery of the deck slab 72.

As shown in FIG. 8A, the outer frame member 20 in this example has a shape with a bent portion along the outer periphery of the deck 72. In this manner, the outer frame member 20 (the outer frame member that forms the wall body 10) according to the embodiment of the present disclosure may have a bent portion. It may also be formed in a curved shape in a plan view.

In addition, a portion of the outer frame member 20 constitutes a wall body, and another portion constitutes a pillar. In this way, the outer frame member 20 according to the embodiment of the present disclosure does not necessarily have to constitute only a wall body, but may also constitute a composite body of a wall body and a pillar.

In this embodiment, reinforcing bars 30 (horizontal bars 32 and vertical bars 34) are fixed to the outer frame member 20 in a factory to form the temporary formwork member S1. The reinforcing bars 30 may also be fixed to the outer frame member 20 at the construction site of the building.

When shipped from the factory, the room unit 70 is fitted with reinforcing bars 30, as well as miscellaneous walls 80, a front door 82, and a bay window 84. Various other components, such as partition walls, equipment for the kitchen and toilet, and floor finishing materials, can be fixed to the room unit 70 as appropriate. In addition, the miscellaneous walls 80, the front door 82, and the bay window 84 do not have to be fixed to the room unit 70.

(How the building is constructed)
In order to construct a building 90 using room units 70, a plurality of room units 70 are arranged side by side as shown by the dashed lines in Fig. 8A. This causes the outer frame members 20 of each room unit 70 to face each other. Although not shown in the drawings, reinforcing bars 30 are also fixed to the outer frame members 20 of the room units 70 shown by the dashed lines in Fig. 8A.

In addition, when the room units 70 are arranged side by side, in the areas where the outer frame members 20 do not face each other, wall reinforcing bars and column reinforcing bars are arranged and then the formwork 86 is placed.

Finally, the wall 10 (see FIG. 1A) is constructed by filling the space between the opposing outer frame members 20 or between the outer frame members 20 and the formwork 86 with filler 40 (see FIG. 1A, etc.), and the building 90 is constructed with the room units 70 connected to each other. The room units 70 are connected horizontally, but they may also be stacked vertically.

<Action and Effects>
In the manufacturing method of a structural member according to an embodiment of the present disclosure, as shown in Figures 2A and 2B, a plurality of guide bars 24 are provided for every predetermined number of layers in an outer frame member 20 formed by stacking wet materials 22. That is, the guide bars 24 are provided for every predetermined height (thickness of one layer of wet material x number of layers N).

As a result, as shown in Figures 3A and 3B, the horizontal reinforcement bars 32 fixed to the guide bars 24 can also be arranged at a predetermined height. This allows for increased reinforcement accuracy in the wall 10 (see Figure 1A) as a structural member.

As shown in Figures 4A and 4B, the reinforcing bars 30 (horizontal bars 32 and vertical bars 34) are fixed to the guide bars 24, so that a throwaway formwork member S1 can be formed in which the wet material 22, guide bars 24, and reinforcing bars 30 are integrated. This throwaway formwork member S1 can be produced in a factory or on-site, and then, as shown in Figures 5A and 5B, arranged opposite each other at the installation site and filled with filler material 40 to produce a wall body 10 as a structural member, thereby reducing the manufacturing work at the installation site.

In addition, in the manufacturing method of the wall 10 as a structural member according to the embodiment of the present disclosure, as shown in Figs. 4A, 4B, and 5A, the reinforcing bars 30 are arranged and then the outer frame members 20 are arranged opposite each other. Therefore, even if the spacing between the outer frame members 20 is narrow, in other words, regardless of the size of the spacing between the outer frame members 20, the reinforcing bars 30 can be arranged. This makes it easy to arrange the reinforcing bars 30 as wall reinforcement.

Even when constructing a wall body 10 as a structural member, if the wall body 10 is thick, the reinforcing bars 30 may be fixed to the outer frame members 20 after the outer frame members 20 are placed opposite each other.

On the other hand, in the manufacturing method of the beam 12 as a structural member, as shown in Figures 6C, 7A, and 7B, the outer frame members 50 are arranged opposite each other, and then the reinforcing bars 60 (stirrups 62 and beam main reinforcement bars 64) are arranged. Therefore, the stirrups 62, which are reinforcing bars that span between the outer frame members 50 arranged opposite each other, can be arranged.

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

These effects can also be obtained in a building 90 constructed using the wall body 10. In addition, in the building 90, as shown in Figures 8A and 8B, the outer frame member 20 is fixed to the floor slab 72, so that a room unit 70 can be formed in which the floor slab 72 and the temporary formwork member S1 are integrated.

The room units 70 are produced in a factory or on-site, and after the reinforcing bars 30 have been arranged, the room units 70 are placed opposite each other at the installation site and filled with the filler material 40 (see FIG. 1A, etc.), allowing the building 90 to be constructed, thereby reducing the construction work at the installation site.

In the building 90, the outer frame member 20 forms a complex of walls and columns, but the embodiment of the present disclosure is not limited to this. The outer frame member of the present disclosure may form a complex of columns and beams, such as the outer frame member 92 shown in FIG. 9. The guide bars in the outer frame member 92 are not shown.

To manufacture the outer frame member 92, as an example, the column portion 92A is layered using wet materials, similar to the outer frame member 50 shown in Figures 6A and 6B. When forming the beam portion 92B, a backing plate and shoring are placed under the beam, and the wet materials are layered. Once the wet materials have hardened, the backing plate and shoring are removed.

By using such an outer frame member 92, the building 90 can be constructed as a pillar and beam structure (rigid frame structure).

As described above, the structural members of the present disclosure can be in various forms, such as walls 10, beams 12, columns, wall and column complexes, and column and beam complexes. Furthermore, these various structural members can be used in the building 90 constructed using the structural members of the present disclosure.
