[0004] [Patent Document 1] JP 2011-427 A [Patent Document 2] JP 2020-110722 A Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, there has been a demand for buildings such as houses to have large flexible spaces that can be used for a variety of purposes, allowing for more appropriate use of the space in accordance with changes in the building's users, such as the residents, and to allow residents to be connected to each other at a reasonable distance.

[0006] Therefore, the present invention aims to provide a building with a large column-free space that can be used for various purposes while maintaining the connection of the column-free space as a single large space. [Means for solving the problem]

[0007] The building of the present invention is a building comprising a column-free space partitioned by a wall structure, and two walls disposed in the column-free space and not in contact with the wall structure, The wall body is formed of a lower runner material whose lower end is fixed to the floor decorative surface with screws, a column material erected on the lower runner material, a column base fixing hardware formed in an L-shape in side view for fixing the column material to the lower runner material, an upper runner material installed between the upper ends of the column materials, a column head fixing hardware for fixing the column material to the upper runner material, a wall material attached across multiple column materials, a capping base fixed onto the upper runner material with screws, and a capping base fixed to the capping base, A building characterized in that the two wall bodies are arranged facing each other, and the two wall bodies have sleeve wall portions formed on both side ends thereof that extend toward the opposing wall body, forming a rectangular space in a plan view between the two wall bodies, the upper ends of each of the walls are lower than the ceiling surface and the lower ends are fixed to the floor decorative surface, the wall structure defines the column-free space in an approximately rectangular shape, the two wall bodies and the sleeve wall portions are arranged so as not to contact the wall structure, and the walls are each arranged so as to face a corner of the column-free space.

[0009] The building of the present invention is characterized in that the sleeve wall portion formed on both ends of at least one of the two walls is formed so that one end extends toward the other wall and the other end extends in a direction away from the other wall.

[0010] The building of the present invention is characterized in that the wall structure defines the column-free space in a substantially rectangular shape, and the two wall bodies are arranged parallel to one side of the wall structure.

[0012] The building of the present invention is characterized in that the two wall bodies have a connecting portion that connects the upper portions of the sleeve walls to each other.

[0013] The building of the present invention is characterized in that the two walls are curved and both ends are close to each other.

[0014] The building of the present invention is characterized in that a shelf portion is fixed to at least one of the two walls, the shelf portion protruding toward the other wall and reinforcing the one wall.

[0015] The building of the present invention is characterized in that the ceiling surface is a surface formed by ceiling material stretched across a plurality of ceiling rafters, and a base plywood is fixed between the plurality of ceiling rafters.

[0016] The building of the present invention is characterized in that a walk-through storage space is formed between the two walls.

[0017] The building of the present invention is characterized in that the two walls have a desk top protruding from at least one wall toward the other wall, and a storage shelf protruding from the other wall toward the one wall. Effect of the Invention

[0018] According to the building of the present invention, the two walls arranged in the column-free space are arranged facing each other without contacting the column structure that divides the column-free space, so that a flow line that allows people to move around is formed around the two walls. In addition, a rectangular space that can be used for a desired purpose is formed between the two walls. And, since the upper ends of the walls are formed lower than the ceiling surface, the entire column-free space above the walls is one space without any separation. By providing such two walls, the column-free space can be gently divided into multiple spaces without completely dividing it, and the column-free space can be used for multiple purposes while maintaining the connection as one large space. In addition, since the lower ends of the walls are fixed to the decorative floor surface, when the walls are removed or moved due to a change in lifestyle, the decorative floor material remains after the walls are removed, so the walls can be easily removed and moved without peeling off the decorative floor material.

[0019] According to the building of the present invention, the two walls have sleeve walls formed on both sides, and these sleeve walls are formed to extend toward the walls facing each other, so that even if the upper end of the wall is formed lower than the ceiling surface, it can be formed to be stronger against horizontal load. Furthermore, by forming the sleeve walls, a rectangular space is formed between the two walls when viewed from above, and this space can be used for various purposes such as storage, a study, and a workspace.

[0020] According to the building of the present invention, one end of the sleeve wall formed on both ends of at least one wall extends toward the other wall, and the other end extends in a direction away from the other wall, so that when viewed from above, both ends of the one wall extend in an H-shape, making the one wall stronger against horizontal load. Also, by extending the sleeve wall in a direction away from the other wall, a recessed space surrounded by the sleeve wall is formed on the opposite side of the one wall to the other wall, and this space can be used for various purposes such as storage, a bench, or a desk top.

[0021] According to the building of the present invention, the wall structure divides the column-free space into a substantially rectangular shape, and the two walls are arranged parallel to one side of the wall structure, so that a rectangular space in plan view is formed between the wall and the wall structure dividing the column-free space, and the column-free space can be gently divided into several rectangular spaces, and each space can be used for a different purpose. In the future, by placing partitions such as partition walls between the wall and the wall structure and dividing the space into several rooms with the walls and partitions, it is possible to create a floor plan that responds to changes in lifestyle due to the growth of children, etc.

[0022] According to the building of the present invention, the wall body is arranged so as to face the corner of the wall structure in the rectangular column-free space, so that a gently divided triangular space can be formed between the wall body and the wall body. The rectangular space between the two walls is arranged in the center in plan view, and four triangular spaces are formed around it, so that each space can be used for a different purpose. In the future, a partition wall or other partition body can be arranged between the wall body and the wall structure, and the space can be divided into several rooms by the wall body and the partition body, so that the floor plan can be adapted to changes in lifestyle due to the growth of children, etc.

[0023] According to the building of the present invention, the two walls have a connecting part that connects the upper parts of the sleeve walls to each other, making the two walls stronger against horizontal loads. Also, since a connecting part is formed that connects the upper parts of the sleeve walls that form an entrance to the space between the two walls, the space between the two walls can be made into an openable and closable space by attaching an opening / closing body such as a curtain or screen that can open and close the entrance to the connecting part.

[0024] According to the building of the present invention, the two walls are curved and formed with both ends close to each other, so that a highly safe wall without corners can be arranged in a column-free space.

[0025] In the building of the present invention, a shelf portion is fixed to at least one of the two walls, protruding toward the other wall and reinforcing that one wall. This means that the shelf portion can be used as a shelf portion on which items can be placed and stored, and can also be used to reinforce the wall, making one of the walls stronger.

[0026] In the building of the present invention, the ceiling surface is a surface formed by ceiling material stretched across multiple ceiling joists, and a base plywood is fixed between the multiple ceiling joists, so that opening and closing bodies such as curtain rails and roller blinds can be attached at any location in the pillar-free space, allowing the pillar-free space to be gently divided.

[0027] According to the building of the present invention, a walk-through storage space is formed between two walls, which creates a circulation line around the two walls and a circulation line through the storage space, shortening the distance required to move between locations within the column-free space. Also, by creating a walk-through storage space, items within the column-free space can be put away, allowing the column-free space to be kept clean.

[0028] According to the building of the present invention, the two walls have a desk top protruding from at least one wall toward the other wall, and a storage shelf protruding from the other wall toward the one wall, so the space between the two walls can be used as a study, workspace, or study corner. Since the space is surrounded by two walls, it is possible to prevent private items from being reflected in the background, for example, during a remote meeting. [Brief description of the drawings]

[0030] First Embodiment Hereinafter, a first embodiment of a building 1a according to the present invention will be described with reference to FIG. 1 to FIG. 5. The building 1a in this embodiment is a two-story detached house. The building 1a is not limited to a detached house, but may be an apartment building, and may be a building 1a other than a house, such as a nursing home, a childcare facility, or an educational facility. In this embodiment, the building 1a is characterized by its second floor, and the first floor of the building 1a may be configured in any layout. On the first floor of the building 1a, for example, although not shown, the entrance and water-related equipment are arranged in a row along the outer wall on the west side, and a large pillar-free space including a living room, dining room, and kitchen without pillars is formed on the east side. In the large space on the first floor of the building 1a, a staircase 5 leading to the second floor, a storage unit under the staircase formed under the staircase, and a home workspace formed by partitioning the large space are also arranged.

[0031] As shown in Figure 1, on the second floor of building 1a, a private room 2 is formed on the south side along the western exterior wall, and a week-in closet 3 is formed on the north side adjacent to the private room 2. A large pillar-free space 4 is formed to the east of the private room 2 and the week-in closet 3. A staircase 5 and an atrium 6 leading from the first floor are provided on the north side of the pillar-free space 4. In addition, a toilet room 7 is provided between the week-in closet 3 and the pillar-free space 4, with an entrance formed on the pillar-free space 4 side.

[0032] The column-free space 4 is a space whose periphery is partitioned by a wall structure 8. In this embodiment, the column-free space 4 is formed as a square of 6m x 6m in plan view, and is a space without columns or partition walls inside. The wall structure 8 is a wall structure 8 provided on the periphery of the column-free space 4 to partition the column-free space 4. In this embodiment, the wall structure 8 includes partition walls 8a formed at the boundary between the column-free space 4 and the private room 2, the boundary between the column-free space 4 and the toilet room 7, and the boundary between the column-free space 4 and the week-in closet 3, partition walls 8b formed at the boundary between the column-free space 4 and the staircase 5, waist-high walls 8c formed at the boundary between the column-free space 4 and the atrium 6, an outer wall 8d on the south side, and an outer wall 8e on the east side. Note that the column-free space 4 in the present invention is not limited to being completely partitioned by the wall structure 8, and may be, for example, a space in which a part of the periphery is connected to another space. In addition, the column-free space 4 is not limited to being a square in plan view, and the planar shape of the column-free space 4 is changed depending on the outer wall and layout of the building 1a.

[0033] Inside the column-free space 4, two walls 9a, 9b are arranged that are not in contact with the wall structure 8 such as the exterior wall or partition wall. The walls 9a, 9b have a main body 10 arranged parallel to each other and sleeve walls 11 formed at both ends of the main body 10. The two walls 9a, 9b are formed in a generally rectangular shape in plan view with the main body 10 being parallel to each other and the sleeve walls 11 being parallel to each other. The upper ends of the walls 9a, 9b are formed lower than the ceiling surface 12. As shown in FIG. 3, the ceiling surface 12 is formed by a ceiling material 14 stretched across a plurality of ceiling girders 13. A base plywood 15 is fixed between the plurality of ceiling girders 13. By providing the base plywood 15 in this way, an opening and closing body such as a curtain rail or a roll screen can be attached to any position on the ceiling surface 12, and the column-free space 4 can be gently divided according to the arrangement of the walls 9a, 9b.

[0034] The walls 9a and 9b are formed with their lower ends fixed to the decorative floor surface 16. As shown in Figs. 4 and 5, the walls 9a and 9b have a steel lower runner 17 fixed to the decorative floor surface 16 with screws (not shown), a column 18 erected on the lower runner 17, a column base fixing hardware 19 formed in an L-shape in side view to fix the column 18 to the lower runner 17, an upper runner 20 installed between the upper ends of the column 18, a column head fixing hardware 21 to fix the column 18 to the upper runner 20, a plasterboard wall material 22 attached across the multiple column materials 18, a capping base 39 fixed to the upper runner 20 with screws (not shown), and a capping 40 fixed to the capping base 39. The walls 9a and 9b may have decorative cloth attached to the surface of the wall material 22.

[0035] The wall bodies 9a, 9b can be removed without peeling off the floor decorative surface 16 by removing the wall material 22, disassembling it by removing the screws joining the various parts, and removing the lower runner material 17 from the floor decorative surface 16.The wall bodies 9a, 9b can be placed in the desired position on the floor decorative surface 16 and fastened with screws, and then the various parts are reassembled, making it possible to easily accommodate future needs for changes to the floor plan.

[0036] 2 and 3, the walls 9a and 9b of this embodiment are two walls 9a and 9b facing each other, and one wall 9a is provided with a horizontal flat desk top 23 made of, for example, plywood. The desk top 23 is formed so as to protrude from one wall 9a toward the other wall 9b, and is fixed to the main body 10 of one wall 9a and the sleeve walls 11 on both sides with screws (not shown). The desk top 23 may have, for example, a drawer, and the one wall 9a may be provided with, for example, an outlet capable of supplying power to a desk lamp or a personal computer.

[0037] The other wall 9b is provided with three horizontal shelves 24 protruding toward the one wall 9a. The shelves 24 are flat plywood plates, and are fixed to the main body 10 and the sleeve wall 11 of the other wall 9b, for example, with screws, so that articles can be placed on and stored thereon, and the shelves 24 reinforce the other wall 9b against horizontal external forces. The other wall 9b is provided with a bench 25 on the opposite side to the one wall 9a. The bench 25 may be fixed integrally to the other wall 9b, or may be placed on the decorative floor surface 16 adjacent to the other wall 9b.

[0038] As shown in FIG. 1, the two walls 9a and 9b are arranged such that the main body 10 faces a corner of the column-free space 4. The corner refers to a corner of the column-free space 4 formed in a rectangular shape in a plan view. Specifically, the main body 10 of one wall 9a faces the southwest corner of the column-free space 4, and the main body 10 of the other wall 9b faces the northeast corner of the column-free space 4. Here, the walls 9a and 9b facing the corner means that the wall structure 8 that divides the column-free space 4 into a substantially rectangular shape and the main body 10 of the walls 9a and 9b form an angle that is not parallel, and means that one diagonal of the column-free space 4 intersects with the main body 10 of the two walls 9a and 9b.

[0039] In this embodiment, the wall structure 8 and the main body parts 10 of the walls 9a, 9b form an angle of 45 degrees, and are arranged so that the diagonal of the column-free space 4 and the main body parts 10 of the walls 9a, 9b are perpendicular to each other. Note that the angle formed by the wall structure 8 and the main body parts 10 of the walls 9a, 9b is not limited to 45 degrees, and is preferably, for example, an angle of about 30 degrees to 60 degrees.

[0040] The main bodies 10 of the two wall bodies 9a, 9b are disposed so as to face the corners of the column-free space 4, and the column-free space 4 is gently divided by a substantially rectangular structure formed by the main bodies 10 of the two wall bodies 9a, 9b and the sleeve wall portions 11. Specifically, the column-free space 4 is gently divided into five spaces: four spaces on the southeast, southwest, northeast, and northwest sides of the two wall bodies 9a, 9b, and the space between the two wall bodies 9a, 9b.

[0041] In this embodiment, the space between the two walls 9a and 9b can be used as a study or workspace. That is, a desk top 23 is formed on one wall 9a, and a shelf 24 is formed on the other wall 9b, so that a person can read, work, hold a web conference, or the like by placing documents on the shelf 24 and sitting on a chair placed on the desk top 23. By using the space between the two walls 9a and 9b as a study or workspace, the space is appropriately separated from other spaces and the outdoors, making it easy to concentrate on reading or work, and also preventing a private space from being reflected in the background during a web conference.

[0042] The northwest space of the two walls 9a and 9b, i.e., the space at the northwest corner of the column-free space 4, is connected to the staircase 5, and two one-seater sofas 26 are arranged there, forming the entrance to the column-free space 4. The southwest space of the two walls 9a and 9b, i.e., the space at the southwest corner of the column-free space 4, is a space where residents can relax, with a sofa 27 and a low table 28 arranged therein. The northeast space of the two walls 9a and 9b, i.e., the space at the northeast corner of the column-free space 4, is a space where residents can relax, with a bench 25 formed in contact with the other wall 9b, an easel 29, and a chair 30 arranged therein, forming a hobby space for residents who enjoy painting, for example. Furthermore, the southeast space of the two walls 9a and 9b, i.e., the space at the southeast corner of the column-free space 4, is a space for children, with a bed 31 arranged therein and a desk 32 arranged next to the bed 31.

[0043] As described above, in the first embodiment, the building 1a has one column-free space 4 divided into five gently separated spaces, making it easy to use each space for a different purpose, and by flexibly changing the purpose of each space in response to changes in lifestyle, the building 1a can be made to suit a person's lifestyle over the long term without requiring large-scale renovations.

[0044] In addition, the two walls 9a, 9b in the first embodiment may have a connecting portion 33 that connects the upper portions of the sleeve wall portions 11 to each other, as shown in Fig. 6. When such a connecting portion 33 is provided, the two walls 9a, 9b support each other, and the walls 9a, 9b can be made stronger against horizontal external forces applied to the two walls 9a, 9b. Since the connecting portion 33 that connects the upper portions of the sleeve wall portions 11 that form an entrance for entering the space between the two walls 9a, 9b is formed, the space between the two walls 9a, 9b can be made into an openable / closable space by attaching an opening / closing body (not shown), such as a curtain or a screen, that can open and close the entrance to the connecting portion 33.

[0045] Second Embodiment Next, a second embodiment of the building 1b of the present invention will be described. The same components as those in the first embodiment will be given the same reference numerals and will not be described. The building 1b of the second embodiment has a different floor plan from the building 1a of the first embodiment except for the column-free space 4. However, since this is a general change in floor plan, the same reference numerals will be given to rooms and the like having the same purpose and will not be described. The column-free space 4 of the building 1b of the second embodiment is formed in a rectangular shape elongated in the north-south direction as shown in FIG. 7. The column-free space 4 is arranged so that the main body parts 10 of the two walls 9c and 9d face the corners of the column-free space 4. Specifically, the main body part 10 of one wall 9c faces the southeast corner of the column-free space 4, and the main body part 10 of the other wall 9d faces the northwest corner of the column-free space 4. In the building 1b of this embodiment, like the building 1a of the first embodiment, the main body portions 10 of the two walls 9c, 9d are arranged so as to face each corner of the column-free space 4, and the column-free space 4 is gently divided into five spaces, namely, four spaces to the southeast, southwest, northeast, and northwest, and the space between the two walls 9c, 9d, by the approximately rectangular structure formed by the main body portions 10 and the sleeve wall portions 11 of the two walls 9c, 9d.

[0046] In the second embodiment, the sleeve wall 11 formed at both ends of at least one of the two walls 9c, 9d, is formed so that one end extends toward the other wall 9d and the other end extends in a direction away from the other wall 9d, and the one wall 9c is H-shaped when viewed from above. The sleeve wall 11 of the one wall 9c extends not only in a direction approaching the other wall 9d but also in a direction away from the other wall 9d, so that the one wall 9c is strong against a horizontal external force applied to the one wall 9c. In addition, the sleeve wall 11 extends in a direction away from the other wall 9d, so that a recessed space surrounded by the sleeve wall 11 is formed on the surface of the one wall 9c opposite the other wall 9d, and this space can be used for various purposes such as storage, benches, and desk tops. In the second embodiment, it is used as a storage shelf.

[0047] In addition, in the building 1b of this embodiment, a hanger pipe 34 is installed between the sleeve wall portions 11 of the two walls 9c, 9d, so that clothes can be stored, and a walk-through storage space 35 is formed between the two walls 9c, 9d. By forming such a walk-through storage space 35, a circulation line around the two walls 9c, 9d and a line of movement through the storage space 35 are formed, so that the distance required for moving between locations within the column-free space 4 can be shortened, and by forming the walk-through storage space 35, items used in other spaces within the column-free space 4 can be put away in the storage space 35, so that the column-free space 4 can be kept clean.

[0048] In the second embodiment, a bed 31 is arranged in the space northwest of the two walls 9c, 9d and in the space southwest of the two walls 9c, 9d, a desk 32 is provided in the northeast space, and a four-seater table 36 is arranged in the southeast space. With this floor plan, as shown by the two-dot chain line, it is possible to form two children's rooms by, for example, arranging a partition wall between the western exterior wall and the other wall 9d and across the north and south of the column-free space 4 in the future. Even if two children's rooms are formed like this, one entrance of the walk-through storage space 35 opens into one child's room and the other entrance opens into the other child's room, so that the storage space 35 can be used from both of the two children's rooms.

[0049] Third Embodiment Next, a third embodiment of the building 1c of the present invention will be described. The same components as those in the first and second embodiments are given the same reference numerals and will not be described. The building 1c of the third embodiment has a different floor plan from the building 1a of the first embodiment except for the column-free space 4. However, since this is a general change in floor plan, the same reference numerals will be given to rooms and the like having the same purpose and will not be described. In the column-free space 4 of the building 1c of the third embodiment, as shown in FIG. 8, the main body 10 of the two walls 9e and 9f is arranged parallel to one side of the wall structure 8. Specifically, the main body 10 of one wall 9e faces the outer wall 8f on the south side as the wall structure 8 forming the column-free space 4 in parallel, and the main body 10 of the other wall 9f faces the partition wall 8g formed on the north side of the column-free space 4 as the wall structure 8 forming the column-free space 4 in parallel.

[0050] With this configuration, the column-free space 4 can be gently divided into several rectangular spaces by the two walls 9e, 9f. By dividing the column-free space 4 into a plurality of rectangular spaces, each space can be used for a different purpose. Unlike the buildings 1a, 1b of the first and second embodiments, the column-free space 4 of the building 1c of the third embodiment can be divided into spaces with good spatial efficiency because the space divided by the two walls 9e, 9f is rectangular.

[0051] The two walls 9e, 9f are each formed with a sleeve wall portion 11, one end of which extends toward the main body portion 10 of the opposing wall body 9e, 9f, and the other end of which extends in a direction away from the main body portion 10 of the opposing wall body 9e, 9f, and the two walls 9e, 9f are each formed in an H shape when viewed from above. A walk-through storage space 35 is formed between the two walls 9e, 9f. A hanger pipe 34 is installed between the sleeve wall portions 11 on the opposing sides of the main body portions 10 of the two walls 9e, 9f, so that clothes can be stored. In addition, a shelf portion 24 is formed on the non-opposing sides of the two walls 9e, 9f, so that documents and the like can be stored.

[0052] Beds 31 are placed at the northwest corner of the column-free space 4 and at the southwest corner of the column-free space 4, and two study desks 32 are placed between the north and south beds 31. A working desk 37 is placed on the south side of one wall 9e, and this working desk 37 and the shelf part 24 formed on the south side of one wall 9e form a workspace. A piano 38 is placed on the north side of the other wall 9f, which serves as a hobby space for the resident. In the column-free space 4 of the building 1c of this embodiment, in the future, a partition wall or other partition body will be placed between the walls 9e, 9f and the wall structure 8, and the space will be divided into several rooms by the walls 9e, 9f and the partition body, allowing the floor plan to be adapted to changes in lifestyle due to the growth of children, etc. Specifically, as shown by the two-dot chain line, by installing a partition wall facing east between two study desks, two children's rooms with beds 31 and study desks 32 can be created. Also, by placing partition walls on both sides of the working space, a home work space where you can concentrate appropriately can be created.

[0053] In the buildings 1a, 1b, 1c in the first, second, and third embodiments, the column-free space 4 and the two walls 9e, 9f are located on the second floor, but the building of the present invention is not limited to this and may be located on the first floor or on the third floor or higher.

[0054] In the first, second and third embodiments, the main body 10 and the sleeve wall 11 of the wall 9a to 9f are all flat plates, and the main body 10 and the sleeve wall 11 are formed so as to be perpendicular to each other, but the wall of the building of the present invention is not limited to this. As shown in FIG. 9, the two wall 9g may be formed in a circular or elliptical arc shape when viewed from above. If the two wall 9g are formed with a shelf 24 protruding in a direction toward the center of the circular or elliptical arc, they can be used as a storage shelf and can be reinforced against horizontal load on the wall. Also, as shown in FIG. 10, the two wall 9h may be formed so that the ends are curved in a circular arc shape when viewed from above, and the ends are close to each other. In this way, if the wall 9g, 9h is formed in a circular arc shape, an elliptical arc shape, or a curved end, no corners are formed on the wall placed in the column-free space 4, so that it is safe, and the column-free space 4 can be a space with a distinctive interior design.
