Description

Building and building construction method

[0001] The disclosed embodiments relate to a building and a building construction method.

[0002] Conventionally, the construction of factories has required a lot of time and labor. Especially in the construction of large-scale factories, multiple processes such as design, foundation work, assembly of structures, and interior work proceed sequentially, so the overall construction period generally becomes longer. Also, in the design of factories, flexible design according to the purpose of use and the layout of production lines is often required, and in order to respond to this, detailed planning from the design stage is necessary.

[0003] Japanese Patent Application Laid-Open No. 2008-261102

[0004] However, in the conventional technology, there is a risk that the construction period of buildings may be prolonged, and there is room for improvement in terms of shortening the construction period and improving construction efficiency.

[0005] One aspect of the embodiment has been made in view of the above, and an object is to provide a building and a building construction method that can shorten the construction period and can be constructed efficiently.

[0006] A building according to one aspect of the embodiment includes a frame unit, a roof portion, a wall portion, and a floor portion. The frame unit is configured by connecting a plurality of rectangular parallelepiped frames formed by a plurality of column portions and beam portions spanned between adjacent column portions. The roof portion is provided at a portion corresponding to the roof in the frame unit. The wall portion is provided at a portion corresponding to the wall in the frame unit. The floor portion is provided at a portion corresponding to the floor in the frame unit.

[0007] According to one aspect of the embodiment, the construction period in the construction of a building can be shortened, and the building can be constructed efficiently.

[0009] The present invention will be described below through embodiments, but these embodiments are not intended to limit the invention as claimed. Furthermore, not all combinations of features described in the embodiments are necessarily essential to the solution of the invention.

[0010] (Embodiment) The building 100 according to the embodiment will be described with reference to Figure 1. Figure 1 is a perspective view showing the building 100 according to the embodiment. In Figure 1, for the sake of explanation, a three-dimensional Cartesian coordinate system is shown, defined by mutually orthogonal X-axis, Y-axis, and Z-axis directions. Such a Cartesian coordinate system may also be shown in other drawings used in the explanation below. Furthermore, the Cartesian coordinate system is the X-axis, Y-axis, and Z-axis directions when the building 100 is in the illustrated state, and does not limit the orientation of the building 100. Also, Figure 1 and Figures 2 and onward described later are all schematic diagrams.

[0011] The building 100 and the construction method for the building 100 according to this embodiment allow for a shorter construction period and more efficient construction. The building 100 is a large-scale building such as a factory or warehouse, and such a large building 100 can be constructed quickly and efficiently. In the above, the use of the building 100 is described as a factory or warehouse, but this is merely an example and not limited to it; it may also be used for other purposes such as a logistics center, office, hospital, residence, or various other facilities.

[0012] To explain in more detail, as shown in Figure 1, the building 100 comprises a frame unit 1 formed by connecting multiple frame bodies 10 (not visible in Figure 1), a roof section 20, a wall section 30, and a floor section 40 (not visible in Figure 1).

[0013] Here, the frame 10, roof section 20, wall section 30, and floor section 40 will be explained with reference to Figures 2 and 3. Figure 2 is a perspective view showing the frame 10, etc. Figure 3 is an exploded perspective view showing the frame 10, etc.

[0014] As shown in Figures 2 and 3, the frame 10 is formed, for example, in the shape of a rectangular parallelepiped, or more precisely, in the shape of a cube. The frame 10 comprises column portions 11 and beam portions 12.

[0015] The column section 11 is formed to extend along the vertical direction (vertical direction; Z-axis direction). There are multiple column sections 11 (for example, four). The four column sections 11 are erected at positions corresponding to the four corners of the cubic frame 10.

[0016] The beam section 12 is formed to extend horizontally (in the X-axis or Y-axis direction). The beam section 12 is spanned between adjacent column sections 11. More specifically, the beam section 12 includes an upper beam section 12a and a lower beam section 12b (see Figure 3). The upper beam section 12a is formed at the top of the frame 10. More specifically, the upper beam section 12a is spanned (provided) between the upper ends 11a of adjacent column sections 11 and is formed to connect (link) the upper ends 11a of the column sections 11. The lower beam section 12b is formed at the bottom of the frame 10. More specifically, the lower beam section 12b is spanned (provided) between the lower ends 11b of adjacent column sections 11 and is formed to connect (link) the lower ends 11b of the column sections 11.

[0017] Thus, the frame 10 is a rectangular parallelepiped (more specifically, cubic) member formed by multiple (in this case, four) column sections 11 and beam sections 12 that span between adjacent column sections 11.

[0018] In the frame 10, the length in the X-axis direction is set to, for example, 15 m. Also, in the frame 10, the length in the Y-axis direction is set to, for example, 15 m, and the length (height) in the Z-axis direction is set to, for example, 15 m. In other words, the column section 11 and the beam section 12 are each set to a length of 15 m. That is, the frame 10 is formed in the shape of a cube with sides of 15 m. Although the dimensions of the frame 10 have been specifically shown above, these are examples and not limiting, and the dimensions of the frame 10 can be set to any value.

[0019] The frame 10 is made of metal, such as steel, but is not limited to this; it may also be made of other materials, such as wood or concrete. Hereinafter, such a frame 10 may be referred to as a "1-unit cubic."

[0020] The frame unit 1 (see Figure 1) is constructed by connecting multiple frame bodies 10 as described above. Multiple sizes of the frame unit 1 are available. For example, in the frame unit 1 according to this embodiment, four sizes are available: S size, M size, L size, and LL size.

[0021] Each of the frame units 1 of the sizes described above will be explained with reference to Figures 4 to 7. Figure 4 is a perspective view showing the S-sized frame unit 1. Figure 5 is a perspective view showing the M-sized frame unit 1. Figure 6 is a perspective view showing the L-sized frame unit 1, and Figure 7 is a perspective view showing the LL-sized frame unit 1. Note that in Figures 5 to 7, and in Figure 8 which will be described later, the frame body 10 that constitutes the frame unit 1 is shown in a simplified manner.

[0022] As shown in Figure 4, the frame unit 1 is formed by arranging multiple frame bodies 10 in a grid pattern. Specifically, if the X-axis direction is defined as "rows" and the Y-axis direction as "columns," the S-sized frame unit 1 is set to 3 rows x 6 columns. That is, the S-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in 3 rows x 6 columns. Specifically, in the S-sized frame unit 1, 3 frame bodies 10 are arranged and connected in a grid pattern in the X-axis direction and 6 in the Y-axis direction. Therefore, the S-sized frame unit 1 is composed of 18 frame bodies 10, with a length of 45 m in the X-axis direction and a length of 90 m in the Y-axis direction. In this way, the S-sized frame unit 1 is a combination of 3 cubic units arranged in 6 rows x 6 columns. The frame bodies 10 are connected (joined) to each other, for example, by standardized fittings or bolts and nuts. This allows the frame bodies 10 to be connected to each other quickly and reliably.

[0023] As shown in Figure 5, the M-sized frame unit 1 is configured in a 6x6 grid. That is, the M-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x6 grid. Specifically, in the M-sized frame unit 1, six frame bodies 10 are arranged and connected in a grid pattern in the X-axis direction and six in the Y-axis direction. Therefore, the M-sized frame unit 1 is composed of 36 frame bodies 10, with a length of 90m in the X-axis direction and a length of 90m in the Y-axis direction. Thus, the M-sized frame unit 1 is made up of 6x6 cubic units combined together.

[0024] As shown in Figure 6, the L-sized frame unit 1 is configured in a 6x12 grid. That is, the L-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x12 grid. Specifically, in the L-sized frame unit 1, 6 frame bodies 10 are arranged and connected in a grid pattern in the X-axis direction and 12 frame bodies 10 in the Y-axis direction. Therefore, the L-sized frame unit 1 is composed of 72 frame bodies 10, with a length of 90m in the X-axis direction and a length of 180m in the Y-axis direction. Thus, the L-sized frame unit 1 is a combination of 6 cubic units arranged in a 12x6 grid.

[0025] As shown in Figure 7, the LL-sized frame unit 1 is configured in a 6x33 grid. That is, the LL-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x33 grid. Specifically, in the LL-sized frame unit 1, 6 frame bodies 10 are arranged and connected in a grid pattern in the X-axis direction and 33 frame bodies 10 in the Y-axis direction. Therefore, the LL-sized frame unit 1 is composed of 198 frame bodies 10, with a length of 90m in the X-axis direction and a length of 495m in the Y-axis direction. Thus, the LL-sized frame unit 1 is composed of 6x33 cubic units combined together.

[0026] In this embodiment, one or more of the four sizes of frame units 1 described above are selected according to the specifications of the building 100. If more than one frame unit 1 is selected, it may be a frame unit 1 of the same size or a frame unit 1 of different sizes. The selected frame units 1 are then installed at the construction site. If there are multiple selected frame units 1, the multiple frame units 1 are combined and installed at the construction site. Here, the joints that connect the frame units 1 are also made to a common specification, thereby enabling the frame units 1 to be connected to each other quickly and reliably.

[0027] Furthermore, the frame unit 1 may be stacked in multiple layers. Figure 8 is a perspective view showing the stacked frame unit 1. As shown in Figure 8, the frame unit 1 may be stacked in multiple layers (two layers in this case) according to the specifications of the building 100. In Figure 8, an example is shown in which two layers of S-sized frame unit 1 are stacked, i.e., a two-story building, but the size of the stacked frame unit 1 and the number of layers (floors) can be set arbitrarily.

[0028] Thus, in this embodiment, as shown in Figure 4, for example, the frame unit 1 with a skeleton structure is installed at the construction site before the wall section 30 and the like are attached.

[0029] Returning to the explanation of Figures 2 and 3, the roof portion 20 is provided on the part of the frame unit 1 that corresponds to the roof. Specifically, the roof portion 20 is provided on the part of the frame body 10 that corresponds to the roof. In other words, the roof portion 20 is formed on the upper surface of the frame body 10 of the frame unit 1. Note that in Figures 2 and 3, one of the multiple frame bodies 10 that make up the frame unit 1 is shown, and the roof portion 20 is provided on the part of this frame body 10 that corresponds to the roof.

[0030] The roof section 20 is formed by bonding together multiple roof panels 21. The roof panels 21 are panels of predetermined sizes. For example, the roof panels 21 are formed in a rectangular shape in plan view, with the length of the short side set to 3 m and the length of the long side set to 15 m. Therefore, in this embodiment, five roof panels 21 are laid out and bonded together on the portion of the frame 10 corresponding to the roof. Specifically, the five roof panels 21 are laid out and bonded together on the upper beam section 12a of the frame 10, which has a rectangular shape (more specifically, a square shape) in top view.

[0031] Figure 3 shows an example where the roof section 20 is formed by five roofing panels 21, but it is not limited to this. For example, the roof section 20 may be formed by one roofing panel 21 with a length and width of 15 m each, or by two to four, or six or more roofing panels 21. Note that the roofing panels 21 are just one example of a panel material.

[0032] The wall portion 30 is provided in the frame unit 1 in the portion corresponding to the wall. Specifically, the wall portion 30 is provided in the portion of the frame body 10 that corresponds to the wall. In other words, the wall portion 30 is formed in the portion of the frame body 10 of the frame unit 1 that becomes the side surface.

[0033] The wall section 30 is formed by bonding together multiple wall panels 31. The wall panels 31 are panels of predetermined sizes. For example, the wall panels 31 are formed in a rectangular shape when viewed from the side, with the length of the short side set to 3 m and the length of the long side set to 15 m. Therefore, in this embodiment, five wall panels 31 are laid out and bonded to the portion of the frame 10 corresponding to the wall. Specifically, the five wall panels 31 are laid out and bonded to the column section 11 and beam section 12 of the frame 10, which have a rectangular shape (more specifically, a square shape) when viewed from the side.

[0034] Although Figure 3 shows an example where there are two wall sections 30, the design is not limited to this. Depending on the position of the frame body 10 in the frame unit 1 and the specifications of the building 100, there may be one wall section 30, three or more, or there may be no wall section 30 at all. Also, although Figure 3 shows an example where the wall section 30 is formed by five wall panels 31, the design is not limited to this. For example, the wall section 30 may be formed by one wall panel 31 with a length and width of 15 m each, or by two to four, or six or more wall panels 31. Note that the wall panel 31 is just one example of a panel material.

[0035] The floor portion 40 is provided in the part of the frame unit 1 that corresponds to the floor. Specifically, the floor portion 40 is provided in the part of the frame body 10 that corresponds to the floor. In other words, the floor portion 40 is formed in the part of the frame body 10 of the frame unit 1 that becomes the lower surface (bottom surface).

[0036] The floor section 40 is formed by bonding together multiple floorboards 41. The floorboards 41 are boards of predetermined sizes. For example, the floorboards 41 are formed in a rectangular shape in plan view, with the length of the short side set to 3 m and the length of the long side set to 15 m. Therefore, in this embodiment, five floorboards 41 are laid out and bonded together in the portion of the frame 10 corresponding to the floor. Specifically, the five floorboards 41 are laid out and bonded together in the lower beam section 12b of the frame 10, which has a rectangular shape (more specifically, a square shape) in a bottom view.

[0037] In Figure 3, an example is shown in which the floor section 40 is formed by five floorboards 41, but it is not limited to this. That is, for example, the floor section 40 may be formed by one floorboard 41 with a length and width of 15 m each, or by two to four, or six or more floorboards 41. Note that the floorboards 41 are just one example of board material.

[0038] In the above example, the roof section 20, wall section 30, and floor section 40 are all formed by bonding multiple sheets of material to the frame unit 1, but the invention is not limited to this. For example, a portion of the roof section 20, wall section 30, and floor section 40 may be formed by bonding multiple sheets of material to the frame unit 1. In other words, in this embodiment, at least one of the roof section 20, wall section 30, and floor section 40 may be formed by bonding multiple sheets of material to the frame unit 1.

[0039] The roof panels 21, wall panels 31, and floor panels 41 are each formed to have various functions such as fire resistance, earthquake resistance, heat insulation, and waterproofing, according to the specifications of the building 100. Furthermore, the roof section 20, wall section 30, and floor section 40 may each be treated with waterproofing, heat insulation, etc., according to the specifications of the building 100. Additionally, the roof section 20 and wall section 30 may each be fitted with features such as doors and windows, according to the specifications of the building 100.

[0040] In Figure 3, an example is shown in which the roof panels 21, wall panels 31, and floor panels 41 are attached from the outside of the frame unit 1 (frame body 10), but this is not the only option. That is, at least one of the roof panels 21, wall panels 31, and floor panels 41 may be attached from the inside of the frame unit 1 (frame body 10).

[0041] In this way, the building 100 is completed by providing the roof section 20, wall section 30, and floor section 40 on the frame body 10 of the frame unit 1 (see Figure 1).

[0042] Next, the construction method of building 100 will be explained with reference to Figure 9. Figure 9 is a flowchart showing the flow of the construction method of building 100 according to this embodiment.

[0043] As shown in FIG. 9, the frame body 10 is manufactured (step S10). Specifically, the frame body 10 including the column part 11 and the beam part 12 is manufactured by an operator, a working robot, or the like. A plurality of such frame bodies 10 are manufactured according to the size of the frame unit 1. For example, when the frame unit 1 is of size S, 18 frame bodies 10 are manufactured. Note that the frame body 10 is manufactured, for example, at a factory or the like, but is not limited thereto, and may be manufactured at other locations such as the installation location of the building 100.

[0044] Next, the plurality of frame bodies 10 are transported to the installation location of the building 100. It is assumed that at the installation location of the building 100, necessary construction work such as groundwork and foundation work has been completed. At the installation location, the plurality of frame bodies 10 are arranged at a predetermined position set in advance by a heavy machine such as a crane. Then, the plurality of frame bodies 10 are connected (joined) by standardized metal fittings and bolts / nuts to manufacture the frame unit 1, and thereby the frame unit 1 is installed at the installation location of the building 100 (step S11).

[0045] Next, the roof part 20, the wall part 30, and the floor part 40 are installed (step S12). Specifically, with respect to the frame unit 1 having a skeleton structure as shown in FIG. 4, the roof part 20, the wall part 30, and the floor part 40 are attached by a heavy machine such as a crane. For example, the roof part 20 is completed by attaching the roof board material 21 to the portion corresponding to the roof of the frame unit 1. Also, the wall part 30 is completed by attaching the wall board material 31 to the portion corresponding to the wall of the frame unit 1. Further, the floor part 40 is completed by attaching the floor board material 41 to the portion corresponding to the floor of the frame unit 1. Here, the board materials constituting the roof part 20, the wall part 30, and the floor part 40 are fixed to the frame body 10 using, for example, bolts or adhesives, but are not limited thereto. Note that the floor part 40 may be attached when the frame unit 1 is installed at the installation location, or may be attached from the inside of the frame unit 1 after the installation of the frame unit 1.

[0046] Next, interior and exterior construction work is carried out on the frame unit 1 to which the roof portion 20, the wall portion 30, and the floor portion 40 are attached (step S13), whereby the building 100 is completed. The above-described interior and exterior construction work includes, for example, work for installing various facilities such as crane rails, electrical equipment, air conditioning equipment, and sanitary equipment inside the frame unit 1, plumbing and wiring work, and work for attaching doors and windows, but is not limited thereto.

[0047] In FIG. 9, an example in which interior and exterior construction work is performed after the roof portion 20 and the like are installed is shown, but the present invention is not limited to this. The installation of the roof portion 20 and the like and the interior and exterior construction work may be performed in parallel, or the installation of the roof portion 20 and the like may be performed after the interior and exterior construction work. As described above, by performing the installation of the roof portion 20 and the like and the interior and exterior construction work in parallel, the construction period can be further shortened.

[0048] As described above, in the building structure 100 according to the embodiment, the frame unit 1, the roof portion 20, the wall portion 30, and the floor portion 40 are provided. The frame unit 1 is configured by connecting a plurality of rectangular parallelepiped frames 10 formed by a plurality of column portions 11 and beam portions 12 spanned between adjacent column portions 11. The roof portion 20 is provided at a portion corresponding to the roof in the frame unit 1. The wall portion 30 is provided at a portion corresponding to the wall in the frame unit 1. The floor portion 40 is provided at a portion corresponding to the floor in the frame unit 1.

[0049] As described above, in the present embodiment, by using the frame unit 1 configured by connecting a plurality of frames 10 formed by the column portions 11 and the beam portions 12, the construction period in the construction of the building 100 can be shortened, and the building 100 can be efficiently constructed. That is, by simply connecting and assembling the unitized and standardized skeleton structure frame 10 on site, a frame unit 1 having a large space can be formed. Therefore, the construction period can be significantly shortened compared to the conventional construction method, and the building 100 can be efficiently constructed.

[0050] Furthermore, in this embodiment, by standardizing and mass-producing materials such as the skeleton frame 10, the roof section 20, the wall section 30, and the floor section 40 (roof boards 21, wall boards 31, and floor boards 41), it becomes possible to ensure a stable supply of materials and uniform quality. In addition, in this embodiment, the unit cost can be reduced due to the benefits of mass production, and labor costs and construction delay costs can be reduced by reducing on-site processing.

[0051] Furthermore, the frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 3x6 grid. Specifically, the S-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 3x6 grid. This allows for a reduction in construction time and efficient construction of buildings 100, such as small factories and warehouses.

[0052] Furthermore, the frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x6 grid. Specifically, the M-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x6 grid. This allows for a reduction in construction time and more efficient construction of buildings 100, such as medium-sized factories and warehouses.

[0053] Furthermore, the frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x12 grid. Specifically, the L-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x12 grid. This allows for a reduction in construction time and more efficient construction of buildings 100, such as large factories and warehouses.

[0054] Furthermore, the frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x33 grid. Specifically, the LL-sized frame unit 1 is constructed by arranging and connecting frame bodies 10 in a 6x33 grid. This allows for a reduction in construction time and efficient construction of buildings 100, such as very large factories and warehouses.

[0055] Furthermore, as described above, by providing multiple sizes for the frame unit 1, if it becomes necessary to expand the production line or storage space in the future, for example, the building 100 can be expanded simply by installing additional frame units 1 adjacent to each other. Also, as described above, by providing multiple sizes for the frame unit 1, flexible selection and combination are possible according to the shape and purpose of the construction site. In addition, it is easy to define new combinations of frame units 1 as needed, making it possible to respond to a variety of construction needs.

[0056] Furthermore, multiple layers of frame units 1 are stacked. This allows for a reduction in construction time and more efficient construction of buildings 100, such as two- or three-story factories and warehouses. Additionally, since stacking multiple layers of frame units 1 is relatively easy, it becomes possible to flexibly respond to changes in the design of the building 100, for example.

[0057] Furthermore, at least one of the roof section 20, wall section 30, and floor section 40 is formed by bonding multiple sheets of predetermined-size board material (roof board material 21, wall board material 31, and floor board material 41) to the frame unit 1. By standardizing the board material in this way, the roof section 20, wall section 30, and floor section 40 can be efficiently attached to the frame unit 1, resulting in a shorter construction period for the building 100 and enabling more efficient construction of the building 100. In addition, for example, the board material for the roof section 20, wall section 30, and floor section 40 can be standardized and mass-produced, resulting in a stable supply of board material and uniform quality.

[0058] Furthermore, the construction method for the building 100 according to this embodiment includes the steps of: manufacturing a rectangular parallelepiped frame 10 formed by a plurality of column sections 11 and beam sections 12 spanning between adjacent column sections 11; manufacturing and installing a frame unit 1 by connecting a plurality of the manufactured frame sections 10; and providing a roof section 20 in the portion corresponding to the roof, a wall section 30 in the portion corresponding to the wall, and a floor section 40 in the portion corresponding to the floor in the installed frame unit 1. This makes it possible to shorten the construction period for the building 100 and to construct the building 100 efficiently.

[0059] The building 100 according to this embodiment is applicable to buildings that require relatively short construction periods, such as factories. Furthermore, the building 100 according to this embodiment is applicable to facilities where future expansion or renovation is anticipated (such as changes to production lines or warehouse expansion). In addition, the building 100 according to this embodiment is applicable to temporary or permanent buildings that require flexible and rapid construction, such as emergency response facilities during disasters or event venues.

[0060] (First Modified Example) Next, the building 100 according to the first modified example will be described with reference to Figure 10. Figure 10 is an exploded perspective view showing the frame 10, etc., of the building 100 according to the first modified example.

[0061] As shown in Figure 10, the frame body 10 of the frame unit 1 of the building 100 according to the first modified example further comprises a column connecting portion 13 and a beam connecting portion 14. For example, the column connecting portion 13 and the beam connecting portion 14 are formed in the parts of the frame body 10 to which board materials (roof board material 21, wall board material 31, and floor board material 41) are attached. The parts of the frame body 10 to which board materials are attached are formed in a grid pattern by the column connecting portion 13 and the beam connecting portion 14.

[0062] Furthermore, the boards (roof boards 21, wall boards 31, and floor boards 41) in the first modified example are each set to have a long side length of 7.5 m and a short side length of 2.5 m. Two boards are placed side by side in the long direction, and six sets of these two boards are placed side by side in the short direction to form the roof section 20, the wall section 30, and the floor section 40.

[0063] To elaborate on the first modified example, the column connecting portion 13 connects a part of the portion (for example, the intermediate portion 11c) formed between the upper end 11a and the lower end 11b of two adjacent column portions 11. Specifically, the column connecting portion 13 is formed to extend along the horizontal direction (X-axis direction or Y-axis direction) and connects the intermediate portions 11c of the column portions 11. For example, if the height of the column portion 11 is 15m, the intermediate portion 11c will be at a height of 7.5m, and the column connecting portion 13 connects these intermediate portions 11c. The column connecting portion 13 is formed at a position corresponding to the boundary between two vertically adjacent wall panels 31. The column connecting portion 13 can also be called a rim.

[0064] The beam connecting portion 14 connects parts of the area formed between the longitudinal ends of two adjacent beam portions 12. For example, in the area where a wall portion 30 is formed in the frame 10, the beam connecting portion 14 is formed to extend along the vertical direction (vertical direction; Z-axis direction). The beam connecting portion 14 connects parts of the area formed between the longitudinal ends of the upper beam portion 12a and the lower beam portion 12b. The beam connecting portion 14 is formed at a position corresponding to the boundary between two horizontally adjacent wall panel materials 31.

[0065] In the frame 10, in the area where the roof section 20 is formed, the beam connecting section 14 is formed to extend horizontally and is also formed in a grid pattern. The beam connecting section 14 connects parts of the sections formed between the longitudinal ends of two adjacent upper beam sections 12a. The beam connecting section 14 is formed at a position corresponding to the boundary between two horizontally adjacent roof boards 21.

[0066] In the frame 10, in the area where the floor portion 40 is formed, the beam connecting portion 14 is formed to extend horizontally and is also formed in a grid pattern. The beam connecting portion 14 connects parts of the portions formed between the longitudinal ends of two adjacent lower beam portions 12b. The beam connecting portion 14 is formed at a position corresponding to the boundary between two horizontally adjacent floor boards 41.

[0067] In this first modification, twelve wall panels 31 are arranged and glued together in a row to the portion of the frame 10 corresponding to the wall. Specifically, twelve wall panels 31 are arranged and glued together to the column portion 11 and beam portion 12 of the frame 10, which have a rectangular shape when viewed from the side. Here, a portion of the wall panels 31 is attached and fixed to a column connecting portion 13 or a beam connecting portion 14 formed at a position corresponding to the boundary with an adjacent wall panel 31.

[0068] In the first modified example, twelve roof panels 21 are arranged and glued together on the portion of the frame 10 corresponding to the roof. Specifically, twelve roof panels 21 are arranged and glued together on the upper beam portion 12a of the frame 10, which has a rectangular shape when viewed from above. Here, a portion of the roof panels 21 is attached and fixed to a beam connecting portion 14 formed at a position corresponding to the boundary with an adjacent roof panel 21.

[0069] In the first modified example, twelve floorboards 41 are laid side by side and glued to the portion of the frame 10 corresponding to the floor. Specifically, twelve floorboards 41 are laid side by side and glued to the lower beam portion 12b of the frame 10, which has a rectangular shape when viewed from below. Here, a portion of the floorboards 41 is attached to and fixed to a beam connecting portion 14 formed at a position corresponding to the boundary with an adjacent floorboard 41.

[0070] As described above, in the building 100 according to the first modified example, the frame body 10 of the frame unit 1 is equipped with column connection parts 13 and beam connection parts 14, so in addition to the effects obtained in the embodiment, the structural strength of the frame body 10 can be improved. Furthermore, the size of the plate material (roof plate material 21, wall plate material 31 and floor plate material 41) can be made more compact to match the positions where the column connection parts 13 and beam connection parts 14 are formed. This compactness can improve the strength of the plate material (roof plate material 21, wall plate material 31 and floor plate material 41). Also, since the column connection parts 13 and beam connection parts 14 are formed at positions corresponding to the boundaries of adjacent plate material, the plate material can be easily and securely attached to the column connection parts 13 and beam connection parts 14 by bolting or the like.

[0071] In the above example, column connection parts 13 and beam connection parts 14 are formed in all parts of the frame 10 where the plate material is attached, but the example is not limited to this, and column connection parts 13 and beam connection parts 14 may be formed in only a part of the parts where the plate material is attached.

[0072] (Second Modification) Next, the building 100 according to the second modification will be described. In the second modification, the dimensions of the frame 10 and the boards in the first modification are changed. Note that the building 100 according to the second modification has the same configuration as the building 100 according to the first modification except for the dimensions, so the following explanation will refer to Figure 10.

[0073] Specifically, in the frame 10 according to the second modified example, the length in the X-axis direction is set to, for example, 14 m. Also, in the frame 10, the length in the Y-axis direction is set to, for example, 14 m, and the length (height) in the Z-axis direction is set to, for example, 14 m. In other words, the column section 11 and the beam section 12 are each set to a length of 14 m. That is, the frame 10 is formed in the shape of a cube with sides of 14 m.

[0074] Furthermore, since the length (height) of the column section 11 is 14 m, the intermediate section 11c is located at a height of 7 m, and the column connecting section 13 connects these intermediate sections 11c together. In addition, to match the dimensions of the frame 10, the board materials (roof board material 21, wall board material 31, and floor board material 41) in the second modified example are set to have a long side length of 7 m and a short side length of 2.34 m, respectively.

[0075] Thus, in the building 100 relating to the second modified example, the same effect as the first modified example can be obtained by setting the dimensions of the frame 10 and the board material as described above.

[0076] (Other Embodiments) The following describes other examples of buildings and construction methods (construction methods) according to the embodiment. Another construction method according to the embodiment is a method for quickly and efficiently constructing large-scale buildings such as factories and warehouses. In this construction method, a cube with sides of 15 meters is defined as a "1-unit cubic," and by standardizing a skeleton structure that combines multiple such units, a construction method that enables a short construction period and flexible design changes is provided. A 1-unit cubic is a shape in which a square beam frame is assembled vertically and horizontally, and is a skeleton composed only of beams. In the construction method according to the embodiment, standard size units of S, M, L, and LL are manufactured in advance, and the construction period can be significantly shortened by simply combining these units at the planned factory construction site. The S size has a skeleton structure of 3 rows x 6 columns, the M size has 6 rows x 6 columns, the L size has 6 rows x 12 columns, and the LL size has 6 rows x 33 columns. In the construction method according to the embodiment, these units are based on 1 cubic (15m) in height, but it is also possible to make them multi-layered depending on the application. The completed skeleton structure is designed so that each cubic unit has a surface area of ​​3m x 15m, and the factory is completed by quickly installing standardized wall panels accordingly. This allows for shorter construction periods, easier expansion and renovation, stable quality, cost reduction, and adaptation to variations. As a result, the construction method according to this embodiment allows for the rapid and efficient construction of large-scale buildings such as factories and warehouses.

[0077] The construction method according to the embodiment includes a generation step, a construction step, and an attachment step. The generation step generates a group of cubic units forming a skeleton structure by combining multiple cubic units, which are rectangular parallelepipeds formed by beam frames. The generation step can combine, for example, an appropriate number of cubic units according to the design of the factory. The generation step can also generate groups of cubic units of, for example, S, M, L, and LL sizes. The generation step can also stack the groups of cubic units in the height direction, for example, according to the use of the factory. The construction step constructs a skeleton structure by combining the generated groups of cubic units. The construction step can also appropriately arrange and combine the groups of cubic units according to the design of the factory. The construction step can also lift the groups of cubic units using a crane and place them in a predetermined position, for example. The construction step can also fix the groups of cubic units with bolts or welds, for example. The attachment step attaches wall members to one surface of the cubic units in the structure. The attachment step can quickly install walls using, for example, standardized wall panels. The attachment process can also involve, for example, lifting the wall panels with a crane and attaching them to the cubic surface. Alternatively, the attachment process can involve fixing the wall panels with bolts or adhesive. This allows for efficient construction of the factory using the construction method according to this embodiment.

[0078] The manufacturing process generates a skeletal structure of cubic units by combining multiple cubic units, which are rectangular parallelepipeds formed by beam frames. In this process, each cubic unit is first manufactured precisely according to the factory's design drawings. Each cubic unit is made of appropriate materials to ensure strength and durability, and reinforcements are used as needed. Depending on the design, different sized cubic units can be combined during the manufacturing process. For example, small-sized cubic units are suitable for small spaces, while medium and large-sized cubic units are suitable for medium to large spaces. Large-sized cubic units are used when particularly large spaces are required. These cubic units can be arranged horizontally as well as stacked vertically, depending on the factory's use and design. This allows for flexible design of the factory's height and hierarchical structure. During the manufacturing process, the joints of each cubic unit are precisely designed to ensure smooth connection during assembly. This improves work efficiency in subsequent construction processes and shortens the overall construction period.

[0079] The construction process involves assembling the generated cubic units to construct a skeletal structure. First, the placement of the cubic units is determined based on the design drawings. Each cubic unit is transported to its designated location using heavy machinery such as cranes and forklifts and precisely positioned. The positioned cubic units are then securely fixed using bolts and welds to ensure the overall stability of the structure. Safety measures are thoroughly implemented during the construction process, especially when working at heights, to ensure the safety of workers. Furthermore, the combination of cubic units is designed to efficiently utilize the internal space of the factory, and the internal layout can be changed as needed. Because the joints of each cubic unit are precisely designed, they can be connected smoothly during assembly, shortening the overall construction period. Additionally, environmentally friendly materials and construction methods are employed, enabling sustainable construction.

[0080] The application process involves attaching wall members to one surface of a single cubic unit in the building. In this process, standardized wall panels are first selected and then customized as needed. The wall panels are designed with thermal insulation and soundproofing in mind, possessing performance characteristics suited to the factory's intended use. During the application process, a crane is used to lift the wall panels and precisely align them with the surface of the cubic unit. During installation, bolts and adhesives are used to securely fasten the panels, ensuring the stability of the wall. The wall panels are installed quickly, contributing to a shorter construction period. Furthermore, the application process involves painting or finishing the surface of the wall panels, enhancing the factory's appearance. This improves the factory's design and harmonizes it with the surrounding environment. The application process ensures precise adjustment of the wall panel's mounting position and angle, maintaining a sense of unity throughout the entire building. As a result, the construction method according to this embodiment achieves efficient and high-quality construction, balancing the functionality and aesthetic appeal of the factory.

[0081] A cubic group is a skeleton structure formed by combining cubic units in a 3x6 grid. A cubic group can form, for example, an S-sized skeleton structure. A cubic group is suitable for the construction of small factories and warehouses, for example. A cubic group can accommodate construction in limited spaces, thus providing a structure suitable for small-scale factory construction.

[0082] A cubic group is a skeleton structure formed by combining 6 cubic units in a 6x6 grid. A cubic group can form, for example, an M-sized skeleton structure. A cubic group is suitable for the construction of medium-sized factories and warehouses. It can accommodate, for example, the design of a standard factory. This provides a structure suitable for the construction of medium-sized factories.

[0083] A cubic group is a skeleton structure formed by combining 6 cubic units in a 12x6 grid. A cubic group can form, for example, an L-sized skeleton structure. Cubic groups are suitable for the construction of large-scale factories and warehouses. They can accommodate the design of factories requiring large spaces, thus providing a structure suitable for large-scale factory construction.

[0084] A cubic group is a skeleton structure formed by combining 6 cubic units in a 33-column arrangement. A cubic group can, for example, form an LL-sized skeleton structure. Cubic groups are suitable for the construction of very large factories and warehouses. They can accommodate the design of factories requiring vast spaces, thus providing a structure suitable for the construction of very large factories.

[0085] Cubic units can be stacked vertically according to their intended use. Cubic units can form multi-story structures, for example, depending on the purpose of a factory. Cubic units can accommodate flexible design changes in the vertical direction. Cubic units can accommodate future expansions or renovations, for example. This allows for flexible design changes in the vertical direction.

[0086] The application process involves attaching standardized wall panels to one side of a single cubic unit. This process allows for rapid wall installation. For example, the application process allows for lifting wall panels with a crane and aligning them with the cubic surface. The application process allows for securing wall panels with bolts or adhesive. This enables rapid wall installation.

[0087] The construction method according to the embodiment is not limited to the example described above, and various modifications are possible, for example, as follows.

[0088] The construction method according to this embodiment may further include an environmental sensor unit. The environmental sensor unit can acquire environmental data such as temperature, humidity, and wind speed at the factory construction site in real time and provide it to the construction unit. This allows the construction unit to formulate an optimal construction schedule according to the environmental conditions. For example, if strong winds are expected, the assembly work of the skeleton structure can be temporarily suspended to ensure safety. Also, if the humidity is high, the unit can instruct the wall attachment section to select an appropriate adhesive to maintain the quality of the wall attachment work. Furthermore, the environmental sensor unit can continuously monitor environmental data even after the factory is completed and provide information to improve the operational efficiency of the factory. For example, it can be used to adjust the air conditioning system to optimize the temperature and humidity inside the factory.

[0089] The construction method according to this embodiment may further include an automated assembly unit. The automated assembly unit can efficiently assemble the skeleton structure using robotic arms and cranes to automate the assembly process. This allows the construction unit to reduce the burden on workers and improve the accuracy of the assembly work. For example, the robotic arm can accurately position one cubic unit and automatically fix the connecting parts. The crane can also quickly lift and position large skeleton structures. Furthermore, the automated assembly unit can monitor the progress of the assembly work in real time and respond immediately if any abnormalities occur. This improves the safety and efficiency of factory construction.

[0090] The construction method according to this embodiment may further include an energy management unit. The energy management unit can provide a system for optimizing energy consumption during the construction and operation of the factory. For example, it can monitor power consumption during construction in real time and issue alerts to reduce unnecessary energy consumption. Furthermore, the energy management unit can provide data to improve energy efficiency even after the factory is completed. For example, it can analyze the usage of lighting and air conditioning systems within the factory and propose an optimal operating schedule. In addition, the energy management unit can support the introduction of renewable energy and propose measures to reduce the environmental impact of the factory.

[0091] The construction method according to this embodiment may further include a safety monitoring unit. The safety monitoring unit can provide a monitoring system to ensure safety at the factory construction site. For example, it can use cameras and sensors to monitor the movements of workers and the status of equipment in real time and issue alerts if dangerous situations occur. The safety monitoring unit can also provide information for safety training to workers, thereby preventing accidents. Furthermore, even after the completion of the factory, the safety monitoring unit can monitor safety during operation and propose improvement measures as needed. This can enhance the safety of the factory and improve the sense of security among workers.

[0092] The construction method according to this embodiment may further include a materials management unit. The materials management unit can manage the inventory of materials necessary for factory construction in real time and realize efficient material supply. For example, it can monitor the usage status of materials and automatically place orders before necessary materials run out. The materials management unit can also manage the storage location and expiration date of materials, thereby reducing material waste. Furthermore, the materials management unit can monitor the quality of materials and respond immediately if there are any quality problems. This can improve the efficiency and quality of factory construction.

[0093] In the construction method according to the embodiment, more flexible construction becomes possible by further diversifying the combination of units. For example, the shape of the units can be changed from cubes to hexagonal prisms. This makes it possible to construct buildings with more complex shapes by combining hexagonal units. Since hexagonal prism units can be arranged closely together without gaps, space efficiency is improved and the strength of the building is increased. Furthermore, hexagonal prism units can be fitted with windows to let in natural light, contributing to improved energy efficiency. Next, by making the unit material lighter, the efficiency of transportation and installation can be improved. For example, by using carbon fiber reinforced plastic (CFRP), the weight of the units can be significantly reduced, making it easier to lift them with cranes. This shortens working time at the construction site and leads to cost reduction. Furthermore, by introducing magnetic coupling technology to the joints of the units, the units can be firmly joined together without using bolts or welding. Magnetic coupling enables rapid assembly and disassembly, making it easy to rearrange and recycle the building. In this way, the standardized construction method can be made to have greater value as an environmentally friendly and sustainable construction method.

[0094] In the construction method according to this embodiment, the functionality of the building can be improved by improving the internal structure of the unit. For example, piping and wiring can be pre-installed inside the unit. This eliminates the need for on-site piping and wiring work, shortening the construction period. Since the piping and wiring are embedded in the walls and floors of the unit and designed to be invisible from the outside, the aesthetics of the building are not compromised. Furthermore, the comfort of the building can be improved by incorporating insulation and soundproofing materials inside the unit. Insulation materials block external temperature changes and maintain a constant indoor temperature. Soundproofing materials block external noise and provide a quiet environment. As a result, the standardized construction method enables the rapid construction of highly habitable buildings. In addition, by incorporating smart sensors inside the unit, the building's condition can be monitored in real time. The smart sensors collect data such as temperature, humidity, and vibration and transmit it to the building's management system. This allows for efficient building maintenance and provides a safe and comfortable environment over a long period of time.

[0095] In the construction method according to this embodiment, the exterior design of the units can be diversified to give the building's appearance individuality. For example, customizable panels can be attached to the exterior walls of the units. This makes it possible to freely change the building's design and realize an appearance that suits the surrounding environment and purpose. Since the customizable panels allow for free selection of colors and patterns, designs that reflect the company's brand image can be applied. Furthermore, by incorporating solar panels into the exterior walls, the building's energy self-sufficiency can be improved. Solar panels not only supplement the building's electricity demand but also generate economic benefits by selling surplus electricity. Next, by attaching greening panels to the exterior walls, the building's environmental impact can be reduced. Greening panels are equipped with soil and irrigation systems for growing plants, allowing the building's exterior walls to be covered with greenery. This is expected to improve the building's insulation and mitigate the urban heat island effect. Through this diversification of exterior designs, the standardized construction method can provide buildings that combine functionality and aesthetics.

[0096] In the construction method according to this embodiment, the efficiency of construction can be further improved by automating the unit assembly process. For example, units can be assembled using a robotic arm. The robotic arm is capable of precise movements and can accurately join and position units. This reduces human error and improves work safety. Furthermore, the robotic arm can operate 24 hours a day, which can significantly shorten the construction period. Next, the placement of units can be monitored using a drone. The drone can check the placement of units in real time from an aerial perspective and make adjustments as needed. This ensures that units are placed accurately and improves the quality of the building. Furthermore, the entire construction process can be optimized using AI. The AI ​​can analyze past data and propose the optimal assembly procedure and material usage. This reduces resource waste and lowers costs. By introducing these automation technologies, the standardized construction method can achieve more efficient and high-quality construction.

[0097] In the construction method according to this embodiment, sustainable construction can be achieved by increasing the reusability of the units. For example, modularizing the units makes it easier to change the use or relocate the building. Modularized units can be easily disassembled and reassembled, extending the lifecycle of the building. This contributes to reducing construction waste and mitigating the environmental burden. Furthermore, by changing the materials of the units to recyclable materials, the circular use of resources can be promoted. For example, by using recycled steel for the structural materials of the units, it becomes possible to recycle the units after use. Next, by incorporating renewable energy systems into the units, the energy self-sufficiency rate of the building can be improved. For example, by installing wind turbines in the units, it becomes possible to supply electricity using wind power. This reduces the energy costs of the building and realizes environmentally friendly construction. Through these improvements in reusability, the standardized construction method can be enhanced in value as a construction method that contributes to a sustainable society.

[0098] The construction method according to this embodiment may further include an environmental sensor unit. The environmental sensor unit can acquire environmental data such as temperature, humidity, and wind speed at the construction site in real time, and optimize the construction process based on this data. For example, if strong winds are expected, crane operations can be temporarily suspended to ensure safety. Also, if humidity is high, the drying time of the adhesive can be adjusted to efficiently proceed with the wall panel attachment process. Furthermore, the environmental sensor unit can transmit the acquired data to the cloud and share information with other construction sites, enabling wide-area weather forecasting and revision of construction plans. As a result, the standardized construction method system can respond flexibly to environmental conditions, achieving shorter construction periods and improved safety.

[0099] The construction method according to this embodiment may further include an energy management unit. The energy management unit can monitor the consumption of electricity and fuel used at the construction site in real time and promote efficient energy use. For example, when electricity consumption reaches its peak, it can automatically turn off the power to unnecessary equipment to save energy. In addition, by monitoring fuel consumption, it is possible to optimize the operating time of heavy machinery and reduce fuel costs. Furthermore, the energy management unit can promote the use of renewable energy and improve the energy self-sufficiency rate of the construction site by installing solar panels and wind turbines. As a result, the standardized construction method system can realize sustainable construction and contribute to reducing the environmental impact.

[0100] The construction method according to this embodiment may further include a quality inspection unit. The quality inspection unit can automatically inspect the joints and mounting condition of wall panels in the assembled cubic group to ensure quality. For example, it can measure the strength of joints with an ultrasonic sensor and issue a warning if it falls below a standard value. It can also measure the mounting angle of wall panels with a laser sensor and prompt correction if it does not match the design drawings. Furthermore, the quality inspection unit can record the inspection results in a database, which can be used for future maintenance and renovation work. As a result, the standardized construction method system can achieve high-quality construction and ensure long-term reliability.

[0101] The construction method according to this embodiment may further include a safety management unit. The safety management unit can monitor the movements of workers at the construction site and improve safety. For example, if a worker enters a dangerous area, it can issue an alarm to warn them. It can also attach sensors to workers' helmets and immediately request rescue if a fall or impact is detected. Furthermore, the safety management unit can monitor the health status of workers and take measures to reduce the risk of overwork and heatstroke. As a result, the standardized construction system can provide a safe and comfortable working environment and contribute to the prevention of occupational accidents.

[0102] The construction method according to this embodiment may further include a communication support unit. The communication support unit facilitates information sharing among workers at the construction site and improves work efficiency. For example, design drawings and work instructions can be shared in real time via tablet devices carried by workers. In addition, voice recognition technology can be used to allow workers to confirm instructions and make reports without using their hands. Furthermore, the communication support unit can provide a translation function between workers who speak different languages, enabling smooth work in multinational teams. As a result, the standardized construction method system can achieve efficient communication and contribute to improved teamwork.

[0103] The construction method according to this embodiment may further include a materials management unit. The materials management unit can grasp the inventory status of materials used at the construction site in real time and realize efficient materials management. For example, it can automatically record the amount of materials used and immediately place orders if inventory is insufficient. It can also optimize the storage location of materials and enable quick retrieval of necessary materials. Furthermore, the materials management unit can analyze the usage history of materials and propose improvement measures to reduce waste. As a result, the standardized construction method system can promote the efficient use of materials and contribute to cost reduction.

[0104] The construction method according to this embodiment may further include a construction simulation unit.

For example, it can use a 3D model to visually confirm the assembly procedure of a group of cubic structures and create an efficient work plan. Furthermore, based on the simulation results, it can optimize the placement of workers and the usage plan of heavy machinery. In addition, the construction simulation unit can consider countermeasures in advance in the event of unexpected troubles and support rapid problem solving. As a result, the standardized construction method system can achieve increased construction efficiency and risk management, contributing to a reduction in construction time.

[0105] The construction method according to this embodiment may further include a waste management unit. The waste management unit can grasp the type and amount of waste generated at the construction site in real time and promote appropriate disposal.
