Description

The present disclosure relates to a method of manufacturing a structural member, a structural member and a building.

Patent Document 1 below discloses a step 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 relatively movable with respect to the support structure to form the reinforcement. An additive manufacturing process is described, comprising:

In this additive manufacturing process, a wire mesh shaped reinforcement is placed inside the support structure forming the mold space prior to injection of the matrix material.

Japanese Patent Publication No. 2018-535861

In the additive manufacturing process of Patent Literature 1, it is difficult to ensure the accuracy of reinforcing bar arrangement because it is necessary to arrange the reinforcing material in the form of a wire mesh before injecting the matrix material.

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 bar arrangement.

The method for manufacturing a structural member according to the first aspect includes a step of laminating wet-processed materials, and forming an outer frame member by providing a plurality of guide bars protruding outward from the wet-processed materials for each predetermined number of layers of the wet-processed materials. a step of fixing and arranging reinforcing bars along the outer frame member to the guide bars; a step of arranging the outer frame members to face each other before or after arranging the reinforcing bars; and filling a filling material between the outer frame members.

In the method for manufacturing a structural member according to the first aspect, a plurality of guide bars are provided for each predetermined number of layers on the outer frame member formed by laminating wet-process materials. That is, a guide bar is installed at each predetermined height.

As a result, the reinforcing bars fixed to the guide bars can also be arranged at predetermined heights. Therefore, it is possible to improve the bar arrangement accuracy of the structural member.

In addition, since the reinforcing bars are fixed to the guide bars, it is possible to form a surrogate formwork member in which the wet material, the guide bars and the reinforcing bars are integrated. A structural member can be manufactured by producing the discarded form members in a factory or on-site, arranging them facing each other at the installation site and filling them with a filler material, so that the manufacturing work at the installation site can be reduced.

A method for manufacturing a structural member according to a second aspect is the method for manufacturing a structural member according to the first aspect, in which the outer frame members are arranged so as to face each other after the reinforcing bars are arranged.

In the method for manufacturing a structural member according to the second aspect, the outer frame members are arranged to face each other after the reinforcing bars are arranged. Therefore, the reinforcement can be arranged even if the space between the outer frame members is narrow. As a result, even when a wall is formed as a structural member, it is easy to arrange reinforcing bars as wall reinforcement.

A method for manufacturing a structural member according to a third aspect is the method for manufacturing a structural member according to the first aspect, in which the reinforcing bars are arranged after the outer frame members are arranged to face each other.

In the method of manufacturing a structural member according to the third aspect, the reinforcing bars are arranged after the outer frame members are arranged to face each other. Therefore, it is possible to arrange reinforcing bars across the outer frame members arranged opposite to each other. As a result, for example, even when beams and columns are formed as structural members, the stirrups of beams straddling between outer frame members and the hoop reinforcements of columns can be arranged.

The structural member of the fourth aspect includes a wet-process material laminated over a plurality of layers, and a plurality of guide lines provided for each predetermined number of layers of the wet-process material and protruding outward from the wet-process material. A frame member, reinforcing bars fixed to the guide bars and arranged along the outer frame member, and a filler filled between the outer frame members arranged to face each other are provided.

In the structural member of 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, a guide bar is installed at each predetermined height. As a result, the reinforcing bars fixed to the guide bars are also arranged at predetermined heights. Therefore, the reinforcing bar arrangement accuracy of the structural member is high.

In addition, since the reinforcing bars are fixed to the guide bars, it is possible to form a surrogate mold member in which the wet material, the guide bars and the reinforcing bars are integrated. A structural member can be manufactured by producing the discarded form members in a factory or on-site, arranging them facing each other at the installation site and filling them with a filler material, so that the manufacturing work at the installation site can be reduced.

The building of the fifth aspect includes a floor slab, a wet-process material fixed to the floor slab and laminated over a plurality of layers, and a predetermined number of layers of the wet-process material provided to the outside of the wet-process material. a room unit having an outer frame member with protruding guide bars; reinforcing bars fixed to the guide bars and arranged along the outer frame members; and a filling material filled between the outer frame members.

In the building of the fifth aspect, a plurality of guide bars are arranged for each predetermined number of layers of the outer frame member formed by laminating wet-type materials. That is, a guide bar is installed at each predetermined height. As a result, the reinforcing bars fixed to the guide bars are also arranged at predetermined heights. Therefore, the reinforcing bar arrangement accuracy of the structural member is high.

In addition, since the reinforcing bars are fixed to the guide bars, it is possible to form a temporary formwork member in which the wet material, the guide bars and the bar arrangement are integrated. In addition, since the outer frame members are fixed to the floor slabs, a room unit can be formed in which the floor slabs and the discarded form members are integrated. A building can be constructed by producing the room units in a factory or on-site, arranging them facing each other at the place where the room units are installed, and filling them with a filler material, so that construction work at the place of installation can be reduced.

According to the present disclosure, it is easy to ensure the bar arrangement accuracy.

Components shown using 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 components may exist.

In addition, descriptions of configurations and reference numerals that are duplicated in each drawing may be omitted. It should be noted that the present disclosure is not limited to the following embodiments, and can be implemented with appropriate modifications such as omitting configurations or replacing with different configurations within the scope of the purpose of the present disclosure.

Also, the direction indicated by the arrow Z is the direction along the vertical direction (vertical direction). It is assumed that the directions indicated by arrows X, Y, and Z in each figure match each other.

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

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 these structural members will be described.

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

(Formation of outer frame member)
In order to manufacture the wall 10, first, the outer frame member 20 shown in FIGS. 2A and 2B is formed. The outer frame member 20 is a member that becomes a discarding form for the filling material 40 to be described later, and includes a wet-process material 22 and guide bars 24 .

The wet material 22 is, for example, mortar, and is discharged in a paste form from a nozzle 100 of a modeling device (eg, a 3D printer, etc.), and formed into a long layer as the nozzle 100 is moved in the lateral direction. By stacking these layers in the vertical direction, a plate-like discarding mold made of the wet material 22 is formed.

The guide bars 24 are reinforcing bars that are provided for each predetermined number of layers of the wet-processed material 22 and protrude outward from the wet-processed material 22 . The “outside” here is a direction intersecting with the longitudinal direction of the wet material 22 . As shown in FIG. 2C, the guide line 24 is installed on the top surface of the wet-processed material 22 each time a predetermined number of layers (N layers) of the wet-processed material 22 are laminated. A plurality of guide streaks 24 are arranged at predetermined intervals (interval M) along the longitudinal direction (X direction) of the wet material 22 .

Thus, the guide streaks 24 are arranged for every "thickness of N layers of the wet material 22" in the vertical direction (Z direction). Further, the guide bars 24 are arranged at intervals of "M" in the horizontal direction (X direction). The vertical direction and the horizontal direction are directions along the in-plane direction of the wall body 10 . The outer frame member 20 is formed by the above steps.

(Arrangement of reinforcing bars)
Next, as shown in FIGS. 3A and 3B, the horizontal reinforcements 32 along the outer frame member 20 are fixed to the guide reinforcements 24 and arranged. Specifically, the lateral reinforcement 32 is placed on and fixed to a plurality of guide reinforcements 24 arranged at the same height. As a result, the horizontal streaks 32 are arranged in the up-down direction (Z direction) for each "thickness of the wet material 22 of N layers (see FIG. 2(C))".

A gap may or may not be formed between the lateral reinforcement 32 and the outer frame member 20 .
When the gap is formed, even if the wet material 22 of the outer frame member 20 has a defective portion, the covering thickness can be secured. On the other hand, if the wet-process material 22 can be applied without defects, the covering thickness can be secured by the thickness of the wet-process material 22 without forming a gap.

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

Note that the vertical reinforcement 34 may be fixed to the horizontal reinforcement 32 . Moreover, the construction order of the vertical reinforcement 34 and the horizontal reinforcement 32 may be changed. In this specification, the horizontal reinforcements 32 and the vertical reinforcements 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 temporary form member S1 is formed.

(Formation of wall)
Next, as shown in FIG. 5A, the temporary frame member S1 to which the reinforcing bars 30 are fixed is arranged to face the outer frame member 20. As shown in FIG. The term “opposed arrangement” means that the sides of the outer frame member 20 to which the reinforcing bars 30 are fixed face each other.

Then, as shown in FIG. 5B, a filling material 40 is filled between the outer frame members 20 arranged to face each other. The filler 40 is concrete, for example. A formwork is installed as necessary at the portion where the outer frame member 20 is not arranged, that is, the end portion in the longitudinal direction (X direction) of the outer frame member 20 to prevent the filling material 40 from leaking.

Through the above steps, the wall 10 is formed using the outer frame member 20 as a temporary mold. As shown in FIG. 5A, the wall body 10 includes wet materials 22 laminated over a plurality of layers, and wet materials 22 provided for each predetermined number of layers (N layers: see FIG. 2C). An outer frame member 20 having a plurality of guide bars 24 projecting outward is provided.

Further, the wall 10 is provided with reinforcing bars 30 (horizontal bars 32 and vertical bars 34 ) that are fixed to the guide bars 24 and arranged along the outer frame member 20 . Furthermore, as shown in FIG. 5B, the wall 10 has a filler 40 filled between the outer frame members 20 arranged opposite to each other.

(Construction location)
When forming the wall 10, as an example, the above-described "formation of the outer frame member" and "arrangement of reinforcing bars" are carried out at the factory. That is, the discarding mold member S1 shown in FIGS. 4A and 4B is manufactured in a factory. Then, the discarded form member S1 manufactured at the factory is carried to a construction site such as a building, and the above-mentioned "wall formation" is carried out.

As another example, the above "formation of the outer frame member" is carried out at the factory. 2A and 2B manufactured at a factory are carried to a construction site such as a building, and the above-described "reinforcing bar arrangement" is carried out to form a formwork member S1. The formwork member S1 may be formed at a work yard at a construction site, in addition to the place where the wall body 10 is constructed. After that, the above "formation of the wall" is performed.

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

(Formation of outer frame member)
In order to manufacture the beam 12, first, the outer frame member 50 shown in FIGS. 6A and 6B is formed. The outer frame member 50, like the outer frame member 20 described above, is a member that serves as a discarding form for the filling material 40, and includes a wet-process material 52 and guide bars 54. As shown in FIG.

Like the wet material 22 described above, the wet material 52 is, for example, mortar, and is discharged in the form of paste from the nozzle of the modeling apparatus. Then, as the nozzle 100 is moved in the horizontal direction, it is formed into an "L shape" in plan view, as shown in FIG. 6B. Moreover, as shown in FIG. 6A, it is formed in layers. By laminating these layers in the vertical direction, an “L-shaped” discarding form in plan view is formed by the wet material 52 .

The “L shape” is a shape formed by one side of a quadrangle and another side in contact with this 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 long sides 52A and short sides 52B.

As with the guide bars 24 described above, the guide bars 54 are installed on top of the laminated wet materials 52 each time a predetermined number of layers of the wet materials 52 are laminated. In addition, a plurality of guide lines 54 are arranged along the extension direction (X direction and Y direction) of the wet material 52 .

The interval and number of the guide bars 54 in the extending direction of the wet material 52 are not particularly limited, but from the viewpoint of facilitating the positioning of the stirrups 62 (see FIGS. 7A and 7B), which will be described later, It is preferable to provide two or more on the long side 52A and one or more on the short side 52B.

Further, from the viewpoint of facilitating the positioning of the beam main reinforcement 64, which will be described later, it is more preferable to provide the guide reinforcement 54 at a location where the beam main reinforcement 64 is installed.

Next, as shown in FIG. 6C, the outer frame members 50 are arranged to face each other. The term “opposed arrangement” means that the sides of the outer frame member 50 from which the guide bars 54 protrude face each other. In addition, in the present embodiment, the two outer frame members 50 are arranged so that the end surfaces of the short sides 52B of each of them are pressed against each other. As a result, the two outer frame members 50 are arranged to have a "U-shaped" cross section.

(Arrangement of reinforcing bars)
Next, as shown in FIGS. 7A and 7B, the stirrups 62 along the outer frame member 50 are fixed to the guide bars 54 and arranged. In this figure, the outer frame member 50 is replaced from the state shown in FIG. 6 so that the lamination direction of the wet materials 52 is along the horizontal direction. That is, the outer frame member 50 is arranged in a posture used as a temporary formwork for the beam 12 shown in FIG. 1B.

The stirrups 62 are fixed to a plurality of guide bars 54 arranged at the same position in the lateral direction (X direction). As shown in FIG. 7B, the stirrups 62 are formed in the shape of a rectangular frame, and arranged across the outer frame members 50 arranged to face each other. Also, the stirrups 62 are fixed to the guide bars 54 of the respective outer frame members 50 .

As a result, the stirrups 62 are arranged at predetermined intervals in the lateral direction (X direction). It should be noted that a gap may or may not be formed between the stirrups 62 and the outer frame member 50 in the same manner as the horizontal reinforcements 32 described above.

Next, the beam main reinforcing bars 64 are fixed to the corners of the stirrups 62 . The beam main reinforcement 64 is arranged along the lamination direction of the wet materials 52, that is, along the extending direction of the beam 12 (see FIG. 1B). Further, the beam main reinforcement 64 is arranged inside the stirrups 62 . Note that the beam main reinforcement 64 may be fixed to the guide reinforcement 54 . Further, the beam main reinforcements 64 are installed at least at the four corners of the stirrups 62, but the number and positions thereof can be increased or decreased as appropriate.

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

(Formation of beams)
Next, as shown in FIG. 7C, the space between the outer frame members 50 arranged to face each other is filled with the filler 40 . A formwork is installed as necessary at the portion where the outer frame member 50 is not arranged, that is, at the end of the outer frame member 50 in the longitudinal direction (X direction) to prevent the filling material 40 from leaking.

Through the above steps, the beam 12 is formed using the outer frame member 50 as a temporary formwork. As shown in FIG. 7A, the beams 12 are composed of a plurality of wet materials 52 laminated over a plurality of layers, and a plurality of guide bars 54 provided for each predetermined number of layers of the wet materials 52 and protruding outward from the wet materials 52. and an outer frame member 50 provided with.

The beam 12 also includes reinforcing bars 60 (stirrups 62 and beam main bars 64) that are fixed to the guide bars 54 and arranged along the outer frame member 50. As shown in FIG. Furthermore, the beam 12 has a filling material 40 filled between the outer frame members 50 arranged to face each other, as shown in FIG. 7C.

(Construction location)
When forming the beams 12, as an example, the above-described "formation of the outer frame member" and "arrangement of reinforcing bars" are carried out at the factory. That is, the discarding mold member S2 shown in FIG. 7B is manufactured at the factory. Then, the discarded form member S2 manufactured at the factory is carried to a construction site such as a building, and the above-mentioned "beam formation" is carried out.

As another example, the above "formation of the outer frame member" is carried out at the factory. Then, the outer frame members 50 manufactured in a factory and shown in FIG. 6B are brought into a construction site such as a building and arranged opposite to each other, and the above-mentioned "reinforcing bar arrangement" is carried out to form the form member S2 shown in FIG. 7B. Form. The formwork member S2 may be formed in a work yard or the like at a construction site in addition to the place where the beam 12 is constructed. After that, the above "formation of the wall" is performed.

<Manufacturing method of structural member (column)>
A pillar can also be manufactured using the outer frame member 50, the reinforcing bars 60, and the filler 40 described above. In order to manufacture the pillar, reinforcing bars 60 shown in FIGS. 7A and 7B are arranged on the outer frame member 50 in the posture shown in FIGS. 6A and 6B. At this time, the stirrups 62 are arranged as hoop reinforcements, and the beam main reinforcements 64 are arranged as column main reinforcements.

When filling the filling material 40, a formwork is installed at the end of the long side 52A of the wet material 52. As shown in FIG. Then, the inside of the outer frame member 50 is closed using the outer frame member 50 and the formwork. A pillar can be manufactured by filling the filler 40 in this state.

In the case of manufacturing a pillar, the wet-process material may be formed in a "U-shape" (angle shape) in a plan view, and the outer frame members may be arranged in a rectangular shape in a state of facing each other.

<Building construction method>
Structural members according to embodiments of the present disclosure may be used in constructing building 90 . As an example, the building 90 can be constructed by manufacturing the room units 70 shown in FIGS. 8A and 8B in a factory and assembling the room units 70 on site.

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

The outer frame member 20 is constructed by laminating the wet-processed material 22 while arranging the guide streaks 24 on the upper portion and outer peripheral portion of the floor slab 72 .

As shown in FIG. 8A, the outer frame member 20 in this example is shaped to have a bent portion along the outer peripheral portion of the floor slab 72 . In this way, the outer frame member 20 (the outer frame member forming the wall 10) according to the embodiment of the present disclosure may have bent portions. Moreover, it may be formed in a curved shape in plan view.

A part of the outer frame member 20 constitutes a wall and the other part constitutes a pillar. In this way, the outer frame member 20 according to the embodiment of the present disclosure does not necessarily constitute only the wall, and may constitute a composite of the wall and the pillar.

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

In addition to the reinforcing bars 30, the rough wall 80, the entrance door 82, and the sweep window 84 are fixed to the room unit 70 at the time of shipment from the factory. In addition, to the room unit 70, various members such as partition walls, equipment such as kitchens and toilets, and floor finishing materials can be fixed as appropriate. Moreover, the rough wall 80, the entrance door 82, and the sweep-out window 84 do not need to be fixed to the room unit 70. - 特許庁

(Building construction method)
In order to construct the building 90 with the room units 70, a plurality of the room units 70 are arranged side by side as indicated by the dashed lines in FIG. 8A. As a result, the outer frame members 20 of the respective room units 70 are arranged to face each other. At this time, although illustration is omitted, the reinforcing bar 30 is also fixed to the outer frame member 20 of the room unit 70 indicated by the dashed line in FIG. 8A.

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

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

<Action 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, an outer frame member 20 formed by laminating wet materials 22 is provided with a plurality of guide lines for each predetermined number of layers. 24 is installed. That is, the guide line 24 is installed at each predetermined height (thickness of one layer of wet material×number of layers N).

As a result, as shown in FIGS. 3A and 3B, the horizontal reinforcements 32 fixed to the guide reinforcements 24 can also be arranged at predetermined heights. Therefore, it is possible to increase the bar arrangement accuracy of the wall 10 (see FIG. 1A) as a structural member.

Further, as shown in FIGS. 4A and 4B, since the reinforcing bars 30 (horizontal reinforcing bars 32 and vertical reinforcing bars 34) are fixed to the guide bars 24, the wet material 22, the guide bars 24 and the reinforcing bars 30 are integrated into a surrogate mold member. S1 can be formed. This discarded formwork member S1 is produced at a factory or on site, and as shown in FIGS. 5A and 5B, by arranging them facing each other at the installation site and filling them with the filler 40, the wall body 10 as a structural member can be manufactured. , the manufacturing work at the installation site can be reduced.

In addition, in the method of manufacturing the wall 10 as a structural member according to the embodiment of the present disclosure, as shown in FIGS. 4A, 4B, and 5A, the outer frame members 20 are arranged to face each other after the reinforcing bars 30 are arranged. 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. This facilitates the reinforcement arrangement of the reinforcing bars 30 as the wall reinforcement arrangement.

Even when the wall 10 is constructed as a structural member, if the thickness of the wall 10 is large, the reinforcing bars 30 may be fixed to the outer frame member 20 after the outer frame member 20 is arranged to face the outer frame member 20 .

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

Note that, even when constructing the beams 12 and columns as structural members, the reinforcing bars 60 may be fixed to the outer frame members 50 before the outer frame members 50 are arranged to face each other.

These effects can also be obtained in the building 90 constructed using the wall 10. FIG. In the building 90, as shown in FIGS. 8A and 8B, the outer frame member 20 is fixed to the floor slab 72, so that the room unit 70 is formed by integrating the floor slab 72 and the discarded frame member S1. can.

The room unit 70 is produced at a factory or on site, the reinforcing bars 30 are arranged, and the building 90 is constructed by arranging the room units 70 facing each other at the installation location of the room unit 70 and filling the filling material 40 (see FIG. 1A, etc.). Therefore, the construction work at the installation site can be reduced.

In addition, in the building 90, the outer frame member 20 constitutes 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 composite of columns and beams, such as the outer frame member 92 shown in FIG. Note that the guide bars in the outer frame member 92 are omitted from the drawing.

In order to manufacture the outer frame member 92, as an example, the column portions 92A are laminated using wet materials 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 a support work are installed under the beam, and the wet materials are laminated.
