Embodiment for Carrying out the Invention
[0020] Hereinafter, a wooden house as a room, an apartment house as a building, and a method for constructing a wooden house as a method for constructing a room according to the present invention will be exemplified and described with reference to the drawings. In each drawing, common members and parts are denoted by the same reference numerals.
[0021] A wooden house 1 as a room according to an embodiment of the present invention is configured by connecting three divided units 1A, 1B, and 1C in the axial direction and stacking them vertically. As shown in FIG. 2, a plurality of wooden houses 1 can be combined with their axial directions parallel to each other to construct an apartment house 100 as a building having a plurality of dwelling units.
[0022] As shown in FIGS. 1, 3, and 4, the wooden house 1 includes a floor portion 10, a ceiling portion 11, and a pair of wall portions 12 and 13. In the present embodiment, the floor portion 10 is constituted by the ceiling portion 11 of the lower floor. That is, the ceiling portion 11 of the wooden house 1 on the lower floor is shared with the floor portion 10 of the wooden house 1 on the upper floor.
[0023] The floor portion 10, the ceiling portion 11, and the pair of wall portions 12 and 13 are each formed of laminated wooden boards. In the present embodiment, the laminated wooden boards are CLT (Cross Laminated Timber) having a structure in which a plurality of wooden boards are laminated and adhered so that the fiber directions are orthogonal to each other, but laminated wooden boards having other structures may also be used.
[0024] The floor section 10 and the ceiling section 11 are each flat, rectangular plates and are arranged parallel to each other. The pair of wall sections 12 and 13 are each flat, rectangular plates and are arranged perpendicular to the floor section 10 and the ceiling section 11, and parallel to each other, at the edges of the floor section 10 and the ceiling section 11. Note that the pair of wall sections 12 and 13 are not necessarily parallel to each other; one wall section may be inclined relative to the other so that the distance between them widens (opens outwards) from one side to the other in the axial direction.
[0025] The floor section 10, the ceiling section 11, and the pair of wall sections 12 and 13 separate the dwelling units of this wooden house 1 from other dwelling units, and do not have passageways or openings such as windows that residents can pass through. However, the floor section 10, the ceiling section 11, and the pair of wall sections 12 and 13 may have holes for passing through water and sewage pipes, gas pipes, electrical wiring, etc., and openings for ventilation.
[0026] End walls 14 and 15 are provided at both ends of the wooden house 1. The end walls 14 and 15 are flat, rectangular plates and are positioned perpendicular to the floor 10, ceiling 11, and the edges of the pair of wall sections 12 and 13, and parallel to each other. The wooden house 1 is isolated from the outside at both ends of its interior space by these end walls 14 and 15. If the pair of wall sections 12 and 13 are arranged to open outwards from one side to the other in the axial direction, the end walls 14 and 15 are connected to the edges of the pair of wall sections 12 and 13 at an appropriate angle. Furthermore, the pair of wall sections 12 and 13 are not necessarily parallel to each other; one may be inclined relative to the other.
[0027] One end wall 14 can be configured with windows 20 and sliding doors. The type, size, and number of windows 20 provided on the end wall 14 can be varied. The other end wall 15 can be configured with an entrance door (not shown) that serves as an exit to the dwelling unit. The other end wall 15 can also be configured with storage space for equipment such as water heaters and electric meters.
[0028] The floor plan of the dwelling unit in wooden house 1 can be set as appropriate, for example, by providing a living room, corridor, kitchen, bathroom, toilet, shelves, storage space, etc. The wall members provided inside the dwelling unit to constitute the above floor plan can all be made of laminated wood (CLT).
[0029] As shown in Figures 1 and 3, in this embodiment, the wooden house 1 is constructed by connecting multiple divided units 1A, 1B, and 1C in the direction of length L and stacking them in the direction of height H, where the width of the end walls 14 and 15 (the width between the outer surface of one wall section 12 and the outer surface of the other wall section 13) is the frontage width W, the height of the wall sections 12 and 13 is the height H, and the length from the outer surface of one end wall 14 to the outer surface of the other end wall 15 (the width of the wall sections 12 and 13) is the length L.
[0030] In this embodiment, the three divided units 1A, 1B, and 1C are connected in the direction of length L, but the number of divided units connected in the direction of length L can be varied. Also, in this embodiment, the three divided units 1A, 1B, and 1C are stacked three times each in the direction of height H to construct a three-story apartment building (structure) 100, but the number of divided units stacked in the direction of height H can be varied.
[0031] The divided unit 1A constitutes one end of the wooden house 1, including the end wall 14; the divided unit 1B constitutes the middle section of the wooden house 1; and the divided unit 1C constitutes the other end of the wooden house 1, including the end wall 15.
[0032] The lengths LA, LB, and LC of the three divided units 1A, 1B, and 1C are all the same, and are one-third the length L of the wooden house 1. That is, the three divided units 1A, 1B, and 1C have the same width, length, and height. However, the lengths of the three divided units 1A, 1B, and 1C may differ from one another.
[0033] The divided unit 1A comprises a divided ceiling section 11A, which is a divided horizontal wall section that constitutes the ceiling section 11, and a pair of divided wall sections 12A and 13A that constitute a pair of wall sections 12 and 13. The divided ceiling section 11A is connected to the upper ends of the pair of divided wall sections 12A and 13A, so that the divided unit 1A has an inverted U-shaped section (C-shaped section) 2A consisting of the divided ceiling section 11A and the pair of divided wall sections 12A and 13A. An end wall 14 is provided at one end of the U-shaped section 2A in the axial direction, and a window 20 or sliding door is pre-installed on the end wall 14. The divided unit 1A can be, for example, a section that constitutes a living room on the inside, and can be configured with interior finishes, electrical wiring, etc., pre-installed.
[0034] The divided unit 1B comprises a divided ceiling section 11B, which is a divided horizontal wall section that constitutes the ceiling section 11, and a pair of divided wall sections 12B and 13B that constitute a pair of wall sections 12 and 13. The divided ceiling section 11B is connected to the upper ends of the pair of divided wall sections 12B and 13B, so that the divided unit 1B has an inverted U-shaped section (C-shaped section) 2B consisting of the divided ceiling section 11B and the pair of divided wall sections 12B and 13B. The U-shaped section 2B can be, for example, a section on the inside where a kitchen or bathroom is installed, and can be configured with electrical wiring and various pipes already installed.
[0035] The divided unit 1C comprises a divided ceiling section 11C, which is a divided horizontal wall section that constitutes the ceiling section 11, and a pair of divided wall sections 12C and 13C that constitute a pair of wall sections 12 and 13. The divided ceiling section 11C is connected to the upper ends of the pair of divided wall sections 12C and 13C, so that the divided unit 1C has an inverted U-shaped section (U-shaped section) 2C consisting of the divided ceiling section 11C and the pair of divided wall sections 12C and 13C. An end wall 15 is provided at one end of the U-shaped section 2C in the axial direction, and an entrance door (not shown) is pre-attached to the end wall 15. The divided unit 1C can be, for example, a section in which a toilet and storage space are provided on the inside, and can be configured with pre-installed electrical wiring and various pipes.
[0036] The wooden house 1 is constructed by connecting the three divided units 1A, 1B, and 1C described above in the axial direction of the inverted U-shaped sections 2A, 2B, and 2C, respectively, and stacking them vertically. Various configurations can be used to connect the divided units 1A, 1B, and 1C to each other, such as a configuration using metal fittings such as plates and fastening means such as screws, a configuration using large-diameter wooden dowels, or a configuration using wooden dowels and metal fittings.
[0037] The axial direction of the U-shaped section 2A is along a straight line parallel to any of the divided floor section 10A, divided ceiling section 11A, and the pair of divided wall sections 12A and 13A that constitute the U-shaped section 2A. Similarly, the axial direction of the U-shaped section 2B is along a straight line parallel to any of the divided floor section 10B, divided ceiling section 11B, and the pair of divided wall sections 12B and 13B that constitute the U-shaped section 2B, and the axial direction of the U-shaped section 2C is along a straight line parallel to any of the divided floor section 10C, divided ceiling section 11C, and the pair of divided wall sections 12C and 13C that constitute the U-shaped section 2B. Furthermore, the axial directions of these U-shaped sections 2A, 2B, and 2C are in the same direction as the direction of the length L of the wooden house 1.
[0038] The wooden house 1 having the above configuration is constructed by connecting multiple divided units 1A, 1B, 1C, each having a U-shaped section 2A, 2B, 2C which consists of divided ceiling sections 11A, 11B, 11C that constitute the ceiling section 11 and a pair of divided wall sections 12A, 12B, 12C, 13A, 13B, 13C that constitute the wall sections 12, 13 respectively, in the axial direction of the U-shaped sections 2A, 2B, 2C and stacking them vertically. As a result, the floor section 10 of the upper floor is formed by the ceiling section 11 of the lower floor.
[0039] Furthermore, the floor section 10 of the lowest level may be constructed using a separate plate-like member 21, rather than relying on the divided units 1A, 1B, and 1C.
[0040] Here, it is conceivable that each of the divided units 1A, 1B, and 1C be configured to have a rectangular tubular section comprising divided ceiling sections 11A, 11B, and 11C that constitute the ceiling section 11, a pair of divided wall sections 12A, 12B, 12C, 13A, 13B, and 13C that constitute the wall sections 12 and 13, and a divided floor section that constitutes the floor section 10. However, in such a configuration, if the divided units having rectangular tubular sections are stacked vertically to form a building with multiple floors, the floor section 10 of the rectangular tubular section on the upper floor and the ceiling section 11 of the rectangular tubular section on the lower floor will be stacked on top of each other, resulting in a problem in that the amount of plate-like material used to constitute the floor section 10 or ceiling section 11 will increase. In particular, if the divided units are made of laminated wood, the amount of wood used will increase.
[0041] In contrast, in the wooden house 1 of this embodiment, each of the divided units 1A, 1B, and 1C comprises divided ceiling sections 11A, 11B, and 11C that constitute the ceiling section 11, and a pair of divided wall sections 12A, 12B, 12C, 13A, 13B, and 13C that constitute the wall sections 12 and 13, respectively, but does not have divided floor sections that constitute the floor section 10. Instead, it has a configuration with U-shaped sections 2A, 2B, and 2C. Therefore, even if the multiple divided units 1A, 1B, and 1C are connected in the axial direction of the U-shaped sections 2A, 2B, and 2C and arranged in a stacked configuration, the floor section 10 of the upper floor will be formed by the ceiling section 11 of the lower floor, and two plate-like members will not be stacked in the floor section 10 or the ceiling section 11. Consequently, according to the wooden house 1 of this embodiment, the amount of plate-like members used can be reduced compared to the case where the divided units have rectangular tubular sections. In particular, when the divided units 1A, 1B, and 1C are formed from laminated wood panels, the amount of wood used can be reduced.
[0042] In this embodiment of the wooden house 1, the multiple divided units 1A, 1B, and 1C are configured to have U-shaped sections 2A, 2B, and 2C, making it easy to increase the ceiling height of the wooden house 1. Specifically, as shown in Figure 5, by placing a main beam 30 between the pair of divided wall sections 12A, 12B, 12C, 13A, 13B, and 13C of one of the vertically overlapping divided units 1A, 1B, and 1C (the upper one in Figure 5) and the ceiling section (divided horizontal wall section) 11 of the other vertically overlapping divided unit 1A, 1B, and 1C (the lower one in Figure 5), the height of the pair of divided wall sections 12A, 12B, 12C, 13A, 13B, and 13C can be raised by the main beam 30, thereby increasing the ceiling height of the wooden house 1.
[0043] As the main beam 30, a laminated wooden board of the same thickness as the divided wall sections 12A, 12B, 12C, 13A, 13B, and 13C can be used, cut to the same length L as the length of the wooden house 1 and to a predetermined height. In this case, after connecting and integrating the three divided units 1A, 1B, and 1C, a pair of main beams 30 can be placed on both sides of the ceiling section 11 formed by these divided units 1A, 1B, and 1C, and then the three divided units 1A, 1B, and 1C can be placed on top of them.
[0044] With this configuration, the ceiling height of the wooden house 1 of this embodiment can be easily set to any desired height.
[0045] A wooden house 1 having the above configuration can be constructed by a wooden house construction method as a room construction method according to one embodiment of the present invention.
[0046] A method for constructing a wooden house according to one embodiment of the present invention includes a manufacturing step of manufacturing the divided units 1A, 1B, and 1C having the above configuration in a factory located in a place different from the construction site where the wooden house 1 to the apartment building 100 will be constructed; a transport step of transporting the divided units 1A, 1B, and 1C manufactured in the factory in the manufacturing step to the construction site individually; and an assembly step of connecting the multiple divided units 1A, 1B, and 1C transported to the construction site in the axial direction of the U-shaped portions 2A, 2B, and 2C and arranging them stacked on top of each other.
[0047] In the above manufacturing process, for example, the divided unit 1A is manufactured by connecting a divided ceiling section 11A, also made of laminated timber (CLT), to the upper ends of a pair of divided wall sections 12A and 13A, each made of laminated timber (CLT), to form a U-shaped section 2A, and then connecting an end wall 14 to the end of the U-shaped section 2A. In addition, during the manufacturing process, interior finishing work, installation of windows or sliding doors, electrical wiring work, etc., can be carried out inside the divided unit 1A to complete the interior.
[0048] Similarly, in the above manufacturing process, the divided unit 1B is manufactured in a form having a U-shaped section 2B by connecting a divided ceiling section 11B, also made of laminated timber (CLT), to the upper ends of a pair of divided wall sections 12B and 13B, each made of laminated timber (CLT). Furthermore, in the manufacturing process, interior finishing work, installation of storage spaces, electrical wiring, plumbing work for water and sewage can be carried out inside the divided unit 1B to complete the interior.
[0049] Similarly, in the above manufacturing process, the divided unit 1C is manufactured by connecting a divided ceiling section 11C, also made of laminated timber (CLT), to the upper ends of a pair of divided wall sections 12C and 13C, each made of laminated timber (CLT), to form a U-shaped section 2C, and then connecting an end wall 15 to the end of the U-shaped section C. Furthermore, in the manufacturing process, interior finishing work, such as the installation of an entrance door, storage space, electrical wiring, and water and sewage piping, can be carried out inside the divided unit 1C to complete the interior.
[0050] In the above-described transport process, the divided units 1A, 1B, and 1C manufactured in the manufacturing process can be transported individually to the construction site, for example, using a truck. When transporting by truck, it is preferable to protect the interior and exterior of the divided units 1A, 1B, and 1C, as well as any installed equipment, as necessary.
[0051] In the assembly process described above, the multiple divided units 1A, 1B, and 1C, which were transported to the construction site in the transport process, are connected in the axial direction of the U-shaped sections 2A, 2B, and 2C, and are stacked vertically. As described above, various configurations can be used for this connection, such as a configuration using metal fittings such as plates and fastening means such as screws, a configuration using large-diameter wooden dowels, or a configuration using wooden dowels and metal fittings. By connecting the multiple divided units 1A, 1B, and 1C and stacking them vertically in the assembly process, the wooden house 1 with the above configuration can be constructed at the construction site.
[0052] In this configuration, each of the divided units 1A, 1B, and 1C has an inverted U-shaped section 2A, 2B, and 2C that does not have a divided floor section that constitutes the floor section 10. Therefore, by simply stacking the divided units 1A, 1B, and 1C of the upper floor on top of the ceiling section 11 made up of the divided units 1A, 1B, and 1C of the lower floor, a wooden house 1 can be constructed in which the floor section 10 of the upper floor and the ceiling section 11 of the lower floor are shared.
[0053] Furthermore, by combining and connecting multiple wooden houses 1 constructed in the above assembly process, with their U-shaped sections 2A, 2B, and 2C parallel to each other, in an orderly fashion both vertically and horizontally, a multi-unit dwelling 100 with multiple dwelling units can be constructed.
[0054] As described above, in the wooden house 1, apartment building 100, and method for constructing the wooden house of this embodiment, the wooden house 1 is constructed by connecting multiple divided units 1A, 1B, and 1C in the axial direction of the U-shaped sections 2A, 2B, and 2C and stacking them vertically. Therefore, before constructing the wooden house 1 at the construction site, the divided units 1A, 1B, and 1C, which have been manufactured in the factory in advance, can be connected and stacked at the construction site in a simple operation, making it possible to easily construct a wooden house 1 in which the floor section 10 of the upper floor and the ceiling section 11 of the lower floor are shared.
[0055] Furthermore, by combining multiple such wooden houses 1 with their axes parallel to each other, a multi-unit dwelling 100 can be easily constructed at the construction site.
[0056] Furthermore, since the wooden house 1 can be configured such that the floor section 10 of the upper floor and the ceiling section 11 of the lower floor are shared, the amount of plate-like members (in this embodiment, laminated wood panels) used can be reduced, thereby lowering the manufacturing cost of the wooden house 1 or apartment building 100.
[0057] Furthermore, in the wooden house 1, apartment building 100, and construction method of the wooden house of this embodiment, the wooden house 1 is constructed by connecting multiple divided units 1A, 1B, and 1C in the axial direction of the U-shaped sections 2A, 2B, and 2C. Therefore, before constructing the wooden house 1 at the construction site, the divided units 1A, 1B, and 1C can be finished in advance at the factory by performing interior work, installation of storage spaces, electrical wiring, plumbing, etc. Consequently, the amount of finishing work that needs to be done as a subsequent process after connecting the multiple divided units 1A, 1B, and 1C at the construction site can be reduced.
[0058] As described above, according to the wooden house 1, apartment building 100, and method for constructing the wooden house of this embodiment, the amount of work required at the construction site when constructing the wooden house 1 to apartment building 100 can be reduced, thereby shortening the construction period. Furthermore, by shortening the construction period, the cost of constructing the wooden house 1 to apartment building 100 can be reduced.
[0059] Furthermore, in the wooden house 1, apartment building 100, and construction method of the wooden house of this embodiment, the construction and finishing work of the divided units 1A, 1B, and 1C can be carried out in the factory, so that the construction and finishing work can be carried out with greater precision and ease than when it is carried out at the construction site.
[0060] Furthermore, in the wooden house 1, apartment building 100, and method for constructing the wooden house of this embodiment, the wooden house 1 is constructed by connecting and stacking multiple prefabricated units 1A, 1B, and 1C manufactured in a factory at the construction site. Therefore, the prefabricated units 1A, 1B, and 1C manufactured in the factory can be transported individually to the construction site using trucks without connecting them to each other. This reduces the size of the cargo loaded onto the trucks compared to transporting the wooden house 1 as is, making the transportation work easier.
[0061] In order to facilitate the transportation of the segmented units 1A, 1B, and 1C from the factory to the construction site, it is preferable that the external dimensions of the segmented units 1A, 1B, and 1C be within the limits of the maximum size (width 2.2m, height 2.8m, length approximately 12m) that can be transported by truck on Japanese roads without obtaining an overloading permit under the Road Traffic Act.
[0062] For example, each of the divided units 1A, 1B, and 1C can have an external size such that the frontage width W is 2.8m or less, the axial length L is 2.2m or less, and the height H is 12m or less.
[0063] Furthermore, each of the divided units 1A, 1B, and 1C can have external dimensions such that the frontage width W is 2.2m or less, the axial length L is 2.8m or less, and the height H is 12m or less.
[0064] Furthermore, each of the divided units 1A, 1B, and 1C can have external dimensions such that the frontage width W is 12m or less, the axial length L is 2.2m or less, and the height H is 2.8m or less.
[0065] In the case of a wooden house with a single, integrated structure that cannot be divided into multiple separate units, if the frontage width is 2.2m or less, the height is 2.8m or less, and the length is 12m or less, the external dimensions will be below the limit size and can be transported by truck without an overload permit. However, if the frontage width exceeds 2.2m or the height exceeds 2.8m, the external dimensions will exceed the limit size and cannot be transported by truck without an overload permit. Therefore, in a single, integrated wooden house, the frontage width is limited to 2.2m or less and the height is limited to 2.8m or less, making it impossible to have a multi-story structure such as a loft or maisonette, and thus the internal space or floor area of the dwelling unit is limited in these respects.
[0066] In contrast, the wooden house 1 of this embodiment uses one of the above external dimensions for each of the three divided units 1A, 1B, and 1C that constitute the wooden house 1. This allows each divided unit 1A, 1B, and 1C to be transportable on the cargo bed 41 of a truck 40, as shown in Figure 6, while the wooden house 1 formed by connecting and stacking the divided units 1A, 1B, and 1C can have an external size that exceeds the transport limit of the truck 40.
[0067] Thus, in this embodiment of the wooden house 1, by setting the three divided units 1A, 1B, and 1C that constitute it to any of the above external dimensions, they can be transported from the factory to the construction site by truck 40 without an overload permit. Therefore, the transport of the divided units 1A, 1B, and 1C by truck 40 can be made even easier.
[0068] As shown in Figure 7 as a modified example, the wooden house 1 can also be configured such that each divided unit 1A, 1B, 1C has a dividing partition wall 16A, 16B, 16C parallel to the dividing wall sections 12A, 12B, 12C, 13A, 13B, 13C between one dividing wall section 12A, 12B, 12C and the other dividing wall section 13A, 13B, 13C, thereby providing a configuration with multiple dwelling units divided by partition walls 22 between a pair of wall sections 12, 13.
[0069] With this configuration, by connecting the three divided units 1A, 1B, and 1C in the axial direction and stacking them vertically, a wooden house 1 with multiple dwelling units can be easily constructed, further reducing the amount of work at the construction site and shortening the construction period.
[0070] In the modified wooden house 1 shown in Figure 7, it is preferable that the three divided units 4A, 4B, and 4C that constitute it have dimensions such that the frontage width W is 12m or less, the axial length L is 2.2m or less, and the height is 2.8m or less. This makes it possible to have multiple dwelling units with sufficient frontage width, while allowing each divided unit 1A, 1B, and 1C to be loaded onto the cargo bed 41 of the truck 40 within the limits of its size.
[0071] Furthermore, the wooden house 4 can be configured in such a way that it has two or more partition walls 22 between a pair of wall sections 12 and 13, resulting in three or more dwelling units divided by these partition walls 22. The number of partition walls 22 or dwelling units can be varied in various ways.
[0072] As shown in Figure 8 as a modified example, the wooden house 1 can also be configured in a multi-story structure partitioned by partition walls 23, with each divided unit 1A, 1B, and 1C having a partition wall 17A, 17B, and 17C parallel to the divided ceiling section (divided horizontal wall section) 11A, 11B, and 11C between one divided wall section 12A, 12B, and 12C and the other divided wall section 13A, 13B, and 13C. In the case shown in Figure 8, the wooden house 1 has a maisonette-style floor plan. That is, the interior space of the wooden house 1 is divided into two levels, upper and lower, by partition walls 23, and partition walls 23 constitute the floor of the second floor.
[0073] With this configuration, the three divided units 1A, 1B, and 1C can be connected axially and stacked vertically, allowing for the easy construction of a multi-story wooden house 1. This further reduces the amount of work required at the construction site and shortens the construction period.
[0074] In the modified wooden house 1 shown in Figure 8, it is preferable that the three divided units 4A, 4B, and 4C that make up the house have dimensions such that the frontage width W is 2.2m or less, the axial lengths LA and LB are 2.8m or less, and the height is 12m or less. This makes it possible to ensure sufficient ceiling height on each floor while allowing each divided unit 1A, 1B, and 1C to be loaded onto the cargo bed 41 of the truck 40 within the limits of its size.
[0075] As shown in Figure 9 as a modified example, the wooden house 1 is configured such that each divided unit 1A, 1B, 1C comprises divided floor sections 10A, 10B, 10C as divided horizontal wall sections constituting the floor section 10, and a pair of divided wall sections 12A, 12B, 12C, 13A, 13B, 13C, and the divided floor sections 10A, 10B, 10C are connected to the lower ends of the pair of divided wall sections 12A, 12B, 12C, 13A, 13B, 13C to form U-shaped sections 3A, 3B, 3C. It is also possible to form a configuration in which divided units 1A, 1B, 1C of this configuration are connected in the axial direction of the U-shaped sections 3A, 3B, 3C and stacked vertically.
[0076] Furthermore, the ceiling section 11 of the uppermost floor can be constructed by placing a separate plate-like member 24 on top of the divided units 1A, 1B, and 1C.
[0077] Even in this modified configuration, the ceiling portion 11 of the lower floor is formed by the floor portion 10 of the upper floor, so, as in the case shown in Figure 4, two plate-like members are not stacked on top of each other in the floor portion 10 or the ceiling portion 11. Therefore, even with the modified configuration shown in Figure 9, the amount of plate-like members used can be reduced compared to the case in which the divided unit has a rectangular tube-shaped portion. In particular, in the case in which the divided units 1A, 1B, and 1C are formed from laminated wood, the amount of wood used can be reduced.
[0078] As shown in Figure 9, even when the wooden house 1 is constructed by connecting U-shaped sections 3A, 3B, 3C of divided units 1A, 1B, 1C in the axial direction and stacking them vertically, as shown in Figure 10 as a further modification, by placing a main beam 30 between the pair of divided wall sections 12A, 12B, 12C, 13A, 13B, 13C of the lower floor divided units 1A, 1B, 1C and the divided floor sections 10A, 10B, 10C of the upper floor divided units 1A, 1B, 1C, the height of the pair of divided wall sections 12A, 12B, 12C, 13A, 13B, 13C can be raised by the main beam 30, thereby increasing the ceiling height of the wooden house 1.
[0079] Furthermore, as shown in Figure 9, even when the wooden house 1 is formed by connecting U-shaped sections 3A, 3B, 3C in the axial direction and stacking them vertically, as shown in Figure 11 as a further modification, each of the divided units 1A, 1B, 1C is provided with a dividing partition wall 16A, 16B, 16C parallel to the dividing wall sections 12A, 12B, 12C, 13A, 13B, 13C between one dividing wall section 12A, 12B, 12C and the other dividing wall section 13A, 13B, 13C, thereby providing a configuration with multiple dwelling units divided by a partition wall 22 between a pair of wall sections 12, 13.
[0080] Furthermore, as shown in Figure 9, even when the wooden house 1 is formed by connecting U-shaped sections 3A, 3B, 3C in the axial direction and stacking them vertically, as shown in Figure 12 as a further modification, each of the divided units 1A, 1B, 1C is provided with divided partition walls 17A, 17B, 17C parallel to the divided ceiling sections (divided horizontal wall sections) 11A, 11B, 11C between one divided wall section 12A, 12B, 12C and the other divided wall section 13A, 13B, 13C, thereby forming a multi-layered structure partitioned by partition walls 23.
[0081] The present invention is not limited to the embodiments described above, and it goes without saying that various modifications are possible without departing from the spirit of the invention.
[0082] For example, in the above embodiment, the wooden house was constructed by connecting two or three divided units, but it is not limited to this, and the number of divided units can be changed in various ways as long as it is constructed by connecting multiple divided units.
[0083] Furthermore, the size of the modular units that make up a wooden house is not limited to the above and can be changed in various ways. In particular, if the configuration is such that it can be transported from the factory to the construction site by truck without an overload permit, then one of the width, length, and height should be 2.2m or less, one of the other should be 2.8m or less, and the remaining one should be 12m or less. However, if the prescribed procedures such as obtaining an overload permit are followed, the height dimension of the modular unit when loaded on a truck can be up to 3.55m.
[0084] Furthermore, although the above embodiment shows a case where laminated wood panels are used for the floor 10, ceiling 11, and wall 12 that form the room, the floor 10, ceiling 11, and wall 12 are not limited to laminated wood panels. Various materials such as PC panels (precast concrete panels), tent materials, gypsum boards, plastic sheets, and metal sheets can be used. In this case, different types of materials can be used for the floor 10, ceiling 11, and wall 12.
[0085] Furthermore, the floor plan of a wooden house, which is essentially a room, can be modified in various ways, not limited to those mentioned above.
[0086] Furthermore, although the above embodiment shows a case where the room or building is an apartment building 100, the building is not limited to an apartment building 100, but may be, for example, a detached house, a hospital, a hotel, a lodging facility, a nursing home for the elderly, a dormitory, etc. Also, the building is not limited to a permanent structure permanently installed in a predetermined location, but may be a temporary structure such as a temporary housing unit erected in the event of a disaster.
