Below, we will explain by example the wooden house as a room, the apartment building as a building, and the method of constructing a wooden house as a room construction method according to the present invention, with reference to the drawings. In each drawing, the same reference numerals are used to denote common members and parts.

The wooden house 1 as a room, which is one embodiment of the present invention as shown in Figure 1, is configured as a housing unit that forms one dwelling unit. The wooden house 1 is configured as one housing unit by connecting three separate units 1A, 1B, and 1C, and has a rectangular parallelepiped outer shape. As shown in Figure 2, multiple wooden houses 1 can be combined to construct an apartment building 100 with multiple dwelling units.

The structure of wooden house 1 is explained in more detail below.

As shown in Figures 1, 3 and 4, the wooden house 1 has a floor 10, a ceiling 11 and a pair of walls 12, 13. The floor 10, the ceiling 11 and the pair of walls 12, 13 are each formed from a wooden laminated board material. In this embodiment, the wooden laminated board material is CLT (Cross Laminated Timber), which is made by stacking and gluing multiple wooden board materials so that the grain directions are perpendicular to each other, but it may also be a wooden laminated board material of another structure.

The floor 10 and the ceiling 11 are each flat, rectangular plates arranged parallel to each other. The pair of walls 12, 13 are each flat, rectangular plates fixed to the edges of the floor 10 and the ceiling 11 perpendicular to the floor 10 and the ceiling 11 and parallel to each other. In other words, the floor 10, the ceiling 11 and the pair of walls 12, 13 are combined and connected in a rectangular tubular shape.

Various configurations can be used to fasten the pair of walls 12, 13 to the floor 10 and ceiling 11, including, for example, a configuration using metal parts such as plates and fastening means such as screws, a configuration using large-diameter wooden dowels, and a configuration using wooden dowels and metal parts.

The floor 10, ceiling 11, and pair of walls 12, 13 separate the dwelling unit that constitutes this wooden house 1 from other dwelling units, and do not have any openings such as passageways or windows through which residents can pass. The floor 10, ceiling 11, and pair of walls 12, 13 may also have holes for passing water and sewerage pipes, gas pipes, electrical wiring, etc., and ventilation openings.

End walls 14, 15 are provided at both ends of the wooden house 1. The end walls 14, 15 are each flat, rectangular plates that are fixed to the edge portions of the floor 10, ceiling 11, and pair of wall portions 12, 13 perpendicularly to these and parallel to each other. These end walls 14, 15 isolate both ends of the interior space of the wooden house 1 from the outside.

One end wall 14 can be configured with a window 20. The type, size, number, etc. of the window 20 provided in the end wall 14 can be changed in various ways. The other end wall 15 can be configured with a front door 21 that serves as an entrance to the dwelling unit. The other end wall 15 can also be configured with a storage space 22 that can store equipment such as a water heater and an electric meter.

The floor plan of the wooden house 1 can be set as appropriate. For example, in this embodiment, the floor plan of the wooden house 1 has a living room 23 on the side of the end wall 14 where the window 20 is provided, a kitchen 25, a bathroom 26, and a toilet 27 are provided from the living room 23 side toward the front door 21 side between the corridor 24 provided between the living room 23 and the front door 21 and one of the walls 12, and a shelf 28 and multiple storage spaces 29 are provided between the corridor 24 and the other wall 13. All of the wall members provided inside the dwelling to configure the above floor plan can be made of laminated wooden board (CLT). The floor plan of the wooden house 1 is not limited to the above and can be changed or set as appropriate.

The wooden house 1 may have a multi-story structure in which a partition wall 16 parallel to the floor 10 is provided between the floor 10 and the ceiling 11. In this embodiment, the wooden house 1 is configured such that the partition wall 16 is provided between the floor 10 and the ceiling 11 in a portion of the house 1 excluding the living room 23, and a loft 30 is provided above the partition wall 16. When the loft 30 is provided, a ladder 31 may be provided on the wall of the living room 23 to facilitate ascent and descent between the loft 30 and the living room 23.

The wooden house 1 is not limited to a multi-story structure with partition walls 16, but may also be a single-story structure without partition walls 16.

As shown in Figures 1 and 5, in the wooden house 1 of this embodiment, the width of the end walls 14, 15 is the frontage width W, the height from the bottom surface of the floor 10 to the top surface of the ceiling 11 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 is the length L. In this embodiment, the wooden house 1 is configured as one housing unit by connecting multiple split units in the direction of length L. As described above, in this embodiment, the wooden house 1 is configured as one housing unit by connecting three split units 1A, 1B, and 1C in the direction of length L. Split unit 1A forms one end side including the end wall 14 of the wooden house 1, split unit 1C forms the other end side including the end wall 15 of the wooden house 1, and split unit 1B forms the middle part between both ends of the wooden house 1.

The lengths LA, LB, and LC of the three split units 1A, 1B, and 1C are the same, and are 1/3 of the length L of the wooden house 1. In other words, the three split units 1A, 1B, and 1C have the same width, length, and height.

The split unit 1A has a rectangular cylindrical part 2A consisting of a split floor part 10A constituting the floor part 10, a split ceiling part 11A constituting the ceiling part 11, and a pair of split wall parts 12A, 13A constituting a pair of wall parts 12, 13. An end wall 14 is provided at one axial end of the rectangular cylindrical part 2A, and a window 20 is attached to the end wall 14 in advance. The split unit 1A forms a living space 23 on the inside, and the interior decoration, electrical wiring, etc. of the living space 23 are provided in advance.

The split unit 1B has a rectangular cylindrical portion 2B consisting of a split floor portion 10B constituting the floor portion 10, a split ceiling portion 11B constituting the ceiling portion 11, and a pair of split wall portions 12B, 13B constituting the pair of wall portions 12, 13. A split partition wall 16B constituting the partition wall 16 is provided inside the rectangular cylindrical portion 2B. A kitchen 25 and a bathroom 26 are also installed inside the split unit 1B, and a shelf 28 and a storage space 29 are also provided. Electrical wiring and various piping, etc. are also installed in advance.

The split unit 1C has a rectangular cylindrical portion 2C consisting of a split floor portion 10C constituting the floor portion 10, a split ceiling portion 11C constituting the ceiling portion 11, and a pair of split wall portions 12C, 13C constituting the pair of wall portions 12, 13. An end wall 15 is provided at one axial end of the rectangular cylindrical portion 2C, and a front door 21 is pre-attached to the end wall 15. A split partition wall 16C constituting the partition wall 16 is provided inside the rectangular cylindrical portion 2C. A toilet 27 is also installed inside the split unit 1C, and multiple storage spaces 29 are also provided, and electrical wiring and various piping are also installed in advance.

The wooden house 1 is constructed by connecting the three split units 1A, 1B, and 1C described above in the axial direction of the respective square cylindrical portions 2A, 2B, and 2C. Various configurations can be used to connect the split 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.

The axial direction of the rectangular cylindrical portion 2A is a direction along a straight line parallel to the divided floor portion 10A, divided ceiling portion 11A, and pair of divided wall portions 12A, 13A that constitute the rectangular cylindrical portion 2A. Similarly, the axial direction of the rectangular cylindrical portion 2B is a direction along a straight line parallel to the divided floor portion 10B, divided ceiling portion 11B, and pair of divided wall portions 12B, 13B that constitute the rectangular cylindrical portion 2B, and the axial direction of the rectangular cylindrical portion 2C is a direction along a straight line parallel to the divided floor portion 10C, divided ceiling portion 11C, and pair of divided wall portions 12C, 13C that constitute the rectangular cylindrical portion 2B. The axial directions of these rectangular cylindrical portions 2A, 2B, 2C are the same as the direction of the length L of the wooden house 1.

A wooden house 1 having the above configuration can be constructed using a wooden house construction method as a room construction method according to one embodiment of the present invention.

The method for constructing a wooden house according to one embodiment of the present invention includes a manufacturing process in which split units 1A, 1B, and 1C having the above-described configuration are manufactured in a factory located at a different location from the construction site where the wooden house 1 or apartment building 100 is constructed, a transport process in which the split units 1A, 1B, and 1C manufactured in the factory in the manufacturing process are transported individually to the construction site, and a connection process in which the multiple split units 1A, 1B, and 1C transported to the construction site are connected in the axial direction of the rectangular cylindrical portions 2A, 2B, and 2C.

In the above manufacturing process, for example, the split unit 1A is manufactured by connecting the split floor section 10A, the split ceiling section 11A, and a pair of split walls 12A and 13A, each made of laminated wooden board (CLT), to form the square tubular section 2A, and then connecting the end wall 14 to the end of the square tubular section 2A. In the manufacturing process, the interior of the split unit 1A can be finished by performing interior work, window 20 installation work, electrical wiring work, etc. Similarly, in the above manufacturing process, the split unit 1B is manufactured into a shape having a square tubular section 2B by connecting the split floor section 10B, the split ceiling section 11B, and a pair of split walls 12B and 13B, each made of laminated wooden board (CLT). In addition, in the manufacturing process, the interior of the split unit 1B can be finished by performing interior work, installation work for the kitchen 25, bathroom 26, shelf 28, and storage space 29, electrical wiring work, water supply and sewerage piping work, etc. Similarly, in the above manufacturing process, the split unit 1C is manufactured by connecting the divided floor section 10C, divided ceiling section 11C, and a pair of divided wall sections 12C and 13C, each of which is made of laminated wooden board (CLT), to form the square cylindrical section 2C, and then connecting the end wall 15 to the end of the square cylindrical section 2C. In addition, in the manufacturing process, the interior of the split unit 1C can be finished by performing interior work, installation work for the front door 21, toilet 27, and storage space 29, electrical wiring work, water supply and sewerage piping work, etc.

In the above-mentioned transportation process, the split units 1A, 1B, and 1C manufactured in the manufacturing process can be transported individually to the construction site, for example, by truck. When transporting by truck, it is preferable to protect the interior and exterior of the split units 1A, 1B, and 1C and the installed equipment, etc., as necessary.

In the above connecting step, the multiple split units 1A, 1B, 1C transported to the construction site in the transport step are connected in the axial direction of the square tubular portions 2A, 2B, 2C. 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 split units 1A, 1B, 1C in the connecting step, the wooden house 1 with the above configuration can be constructed at the construction site.

In addition, a condominium 100 with multiple dwelling units can be constructed by combining and connecting multiple wooden houses 1 constructed in the above-mentioned connecting process vertically and horizontally with the square cylindrical portions 2A, 2B, 2C parallel to each other. In this case, a wooden house 1 can be constructed above or to the side of another wooden house 1 by connecting multiple split units 1A, 1B, 1C in sequence above or to the side of an already constructed wooden house 1. Also, gaps can be provided between the wooden houses 1 to allow for wiring, piping, etc. to be arranged.

In this way, in the wooden house 1, apartment house 100, and wooden house construction method of this embodiment, multiple split units 1A, 1B, 1C are connected in the axial direction of the rectangular cylindrical portions 2A, 2B, 2C to construct the wooden house 1, so that before constructing the wooden house 1 at the construction site, the wooden house 1 can be easily constructed by the simple task of simply connecting the split units 1A, 1B, 1C that have been manufactured in advance at a factory at the construction site. In addition, by combining multiple such wooden houses 1 with their axes parallel to each other, the apartment house 100 can be easily constructed at the construction site.

Furthermore, in the wooden house 1, apartment building 100, and wooden house construction method of this embodiment, multiple split units 1A, 1B, 1C are connected in the axial direction of the rectangular cylindrical portions 2A, 2B, 2C to construct the wooden house 1, so that before constructing the wooden house 1 at the construction site, the split units 1A, 1B, 1C can be finished in advance at a factory by carrying out interior work, installation of the kitchen 25, bathroom 26, toilet 27, shelves 28, and storage space 29, electrical wiring work, water supply and sewerage piping work, etc. Therefore, it is possible to reduce the amount of finishing work to be carried out as a post-process after connecting multiple split units 1A, 1B, 1C at the construction site.

As described above, according to the wooden house 1, apartment house 100, and method for constructing a wooden house of this embodiment, the amount of work at the construction site when constructing the wooden house 1 to the apartment house 100 can be reduced, and the construction period for the construction can be shortened. Furthermore, by shortening the construction period, the costs for constructing the wooden house 1 to the apartment house 100 can be reduced.

In addition, in the wooden house 1, apartment building 100, and wooden house construction method of this embodiment, the construction and finishing work of the split units 1A, 1B, and 1C can be carried out in a factory, so that the construction and work can be carried out more accurately and easily than if it were carried out at a construction site.

Furthermore, in the wooden house 1, apartment building 100, and wooden house construction method of this embodiment, the wooden house 1 is constructed by connecting multiple split units 1A, 1B, and 1C manufactured in a factory at the construction site, so that the split units 1A, 1B, and 1C manufactured in the factory can be transported to the construction site individually by truck without being connected to each other. This makes it possible to reduce the size of the cargo loaded onto the truck and facilitate the transportation work compared to when the wooden house 1 is transported as is.

To facilitate easy transportation of the split units 1A, 1B, and 1C from the factory to the construction site, it is preferable that the external dimensions of the split units 1A, 1B, and 1C be equal to or smaller than the limit size (2.2 m width, 2.8 m height, and approximately 12 m length) that allows transportation by truck on Japanese roads without obtaining a load permit beyond the limit under the Road Traffic Act.

For example, each of the split units 1A, 1B, and 1C can have an exterior size in which the width W is 2.8 m or less but greater than 2.2 m, the length L in the axial direction is 2.2 m or less, and the height H is greater than 2.8 m but less than 12 m. In the wooden house 1 of this embodiment, the three split units 1A, 1B, and 1C that make it up each have a width W of 2.8 m, a length L of 2.2 m, and a height H of approximately 4.0 m.

If a wooden house is an integrated structure that cannot be divided into multiple separate units, then if the width of the frontage is 2.2m or less, the height is 2.8m or less, and the length is 12m or less, then the exterior dimensions are below the limit size, and it can be transported by truck without a permit for loading beyond the limit. However, if the width of the frontage exceeds 2.2m or the height exceeds 2.8m, the exterior dimensions exceed the limit size, and it cannot be transported by truck without a permit for loading beyond the limit. Therefore, for integrated wooden houses, the width of the frontage is limited to 2.2m or less, and the height is limited to 2.8m or less, and it cannot be made into a multi-story structure such as a loft or maisonette, and in these respects the interior space or floor area of the dwelling unit is limited.

In contrast, the wooden house 1 of this embodiment has an exterior size that exceeds the limit size, with a width W of 2.8 m, and with the addition of a loft 30, a height H of approximately 4.0 m and a length L of 6.6 m. This means that the interior space or floor area is larger than that of an integrated wooden house within the limit size. However, the three separate units 1A, 1B, and 1C that make up the wooden house 1 each have a width W of 2.8 m, a height H of approximately 4.0 m, and lengths LA, LB, and LC of 2.2 m, so that the house can be laid on its side with the floor 10 and ceiling 11 facing forward and backward and the pair of walls 12, 13 facing upward and downward, and can be loaded onto the bed 41 of a truck 40 within the limit size range. As shown in FIG. 6, for example, when loading the split unit 1A onto the bed 41 of the truck 40, the split unit 1A can be loaded onto the bed 41 of the truck 40 within the maximum size range by laying the split unit 1A on its side with the split floor 10A and split ceiling 11A facing in the front-to-rear direction of the truck 40 and the pair of split walls 12A, 13A facing in the up-down direction.

In this way, in the wooden house 1 of this embodiment, the three constituent split units 1A, 1B, 1C have exterior dimensions of a frontage width W of 2.8 m or less but greater than 2.2 m, an axial length L of 2.2 m or less, and a height H of 2.8 m or more but less than 12 m, so that they can be transported from the factory to the construction site by truck 40 without an over-loading permit. This makes it even easier to transport the split units 1A, 1B, 1C by truck 40.

In addition, by making the three split units 1A, 1B, 1C each have an exterior size with a frontage width W of 2.8 m or less but greater than 2.2 m, axial lengths LA, LB, LC of 2.2 m or less, and height H of 2.8 m or more but less than 12 m, the three split units 1A, 1B, 1C can be transported from the factory to the construction site by truck 40 without an over-loading permit, while the wooden house 1 can be made into a multi-story structure with a loft 30, expanding the interior space or floor area.

Figure 7 is an exploded perspective view of a wooden house 3 as a room in another embodiment of the present invention, Figure 8 is a diagram showing an example of the layout of the first and second floors of the wooden house 3 shown in Figure 7, Figure 9 is a diagram showing another example of the layout of the first and second floors of the wooden house 3 shown in Figure 7, and Figure 10 is an explanatory diagram showing the manner in which the split unit 3A shown in Figure 7 is transported by truck 40. Note that in Figures 7 to 10, the same reference numerals are used to denote the components described above.

The room of the present invention is not limited to a configuration in which three split units 1A, 1B, and 1C are connected, as in the wooden house 1 shown in Figure 1, but can also be a configuration in which two split units 3A and 3B are connected, as in the wooden house 3 shown in Figure 7.

As shown in Figure 8, in another embodiment of the wooden house 3, the dwelling unit is configured as a maisonette. That is, between the divided floor sections 10A, 10B and the divided ceiling sections 11A, 11B of the split units 3A, 3B, partition walls 16 (partition walls 16A, 16B) are provided parallel to the divided floor sections 10A, 10B, respectively, and the partition walls 16 divide the interior space of the wooden house 3 into two layers, an upper and lower, and the partition walls 16 form the floor of the second floor.

For example, as shown in FIG. 8(a), a wooden house 3 configured as a maisonette can have a front door 21, a living room 23, and a toilet 27 on the first floor, and as shown in FIG. 8(b), a kitchen 25 and a bathroom 26 on the second floor, as well as a spiral staircase 32 for accessing the upper and lower floors. However, the layout can be changed in various ways, for example, as shown in FIG. 9(a), a front door 21, a living room 23, and a kitchen 25 on the first floor, and as shown in FIG. 9(b), a bathroom 26 and a toilet 27 on the second floor, as well as a straight staircase 32 for accessing the upper and lower floors.

In another embodiment of the wooden house 3, the two split units 3A and 3B that make it up preferably have a width W of 2.2 m or less, axial lengths LA and LB of 2.8 m or less but greater than 2.2 m, and heights of 2.8 m or more but less than 12 m. In the illustrated example, the two split units 3A and 3B that make up the wooden house 3 each have a width W of 2.2 m, a length L of 2.8 m, and a height H of approximately 5.6 m.

This allows the wooden house 3 to have a large floor area as a maisonette, while the split units 3A and 3B that make up the house can be laid sideways with the floor 10 and ceiling 11 facing forward and backward and the pair of walls 12 and 13 facing left and right, making it possible to mount the house on the bed 41 of the truck 40 within the limit size range. As shown in FIG. 10, for example, when loading the split unit 3A onto the bed 41 of the truck 40, the split unit 3A can be laid sideways with the split floor 10A and split ceiling 11A facing forward and backward of the truck 40 and the pair of split walls 12A and 13A facing left and right, making it possible to mount the house on the bed 41 of the truck 40 within the limit size range.

Therefore, the two separate units 3A and 3B that make up the wooden house 3 can be transported from the factory to the construction site by truck 40 without an extra-loading permit, while the wooden house 3 can be constructed as a multi-story house with a maisonette as the dwelling unit, expanding the interior space or floor area.

Figure 11 is a cross-sectional view in plan of a wooden house 4 as a room in yet another embodiment of the present invention, and Figure 12 is a cross-sectional view in plan of a modified example of the wooden house 4 shown in Figure 11. Note that in Figures 11 and 12, the same reference numerals are used to denote the previously described members.

The wooden house 1 shown in Figure 1 has only one dwelling unit, but by providing a partition wall between a pair of walls 12, 13, it can also be configured to have multiple dwelling units separated by partition walls between the pair of walls 12, 13.

For example, the wooden house 4 shown in FIG. 11 has one partition wall 33 between a pair of walls 12, 13, and this partition wall 33 divides the interior space into two over the entire range between one end wall 14 and the other end wall 15, resulting in two dwelling units separated by the partition wall 33 between the pair of walls 12, 13. The floor plan of each dwelling unit of the wooden house 4 shown in FIG. 11 is basically the same as that of the wooden house 1 shown in FIG. 1, except that there is no loft.

The wooden house 4 shown in FIG. 11 is similar to the wooden house 1 shown in FIG. 1 in that it is made up of three connected split units 4A, 4B, and 4C. Each of the split units 4A, 4B, and 4C has a split partition wall 33A, 33B, and 33C between the split wall section 12A, 12B, and 12C and the split wall section 13A, 13B, and 13C. Therefore, by connecting the three split units 4A, 4B, and 4C, a wooden house 4 with two dwelling units can be constructed.

For example, as shown in FIG. 12, the wooden house 4 can be configured with two partition walls 33 between a pair of wall sections 12, 13, so that the house has three dwelling units separated by these partition walls 33. The number of partition walls 33 or dwelling units can be changed in various ways.

The wooden house 4 shown in FIG. 12, like the wooden house 4 shown in FIG. 11, is configured by connecting three split units 4A, 4B, and 4C. Each split unit 4A, 4B, and 4C has two dividing partition walls 33A, 33B, and 33C between the dividing wall sections 12A, 12B, and 12C and the dividing wall sections 13A, 13B, and 13C. Therefore, by connecting the three split units 4A, 4B, and 4C, a wooden house 4 with three dwelling units can be constructed.

In the wooden house 4, it is preferable that the three split units 4A, 4B, and 4C that make up the wooden house 4 have a width W of more than 2.8 m and less than 12 m, an axial length L of less than 2.2 m, and a height of less than 2.8 m and greater than 2.2 m. In both the cases shown in Figure 11 and Figure 12, the three split units 4A, 4B, and 4C that make up the wooden house 4 each have a width W of 6.0 m, a length L of 2.2 m, and a height H of 2.8 m.

This allows a wooden house 4 with multiple dwelling units to be constructed by connecting the three split units 4A, 4B, and 4C, further reducing the amount of work at the construction site and shortening the construction period, while the three split units 4A, 4B, and 4C that make up this can be oriented so that the floor 10 and ceiling 11 face up and down and the pair of wall sections 12 and 13 face forward and backward, making it possible to load the three split units 4A, 4B, and 4C into the truck 40 within the maximum size range on the loading platform 41.

The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications are possible without departing from the spirit of the invention.

For example, in the above embodiment, the wooden house is constructed by connecting two or three split units, but this is not limited to this, and the number of split units can be changed in various ways as long as the wooden house is constructed by connecting multiple split units.

The size of the split units that make up a wooden house is not limited to the above and can be changed in various ways. In particular, if the structure is designed to be transportable from the factory to the construction site by truck without an overloading permit, one of the width, length and height can be 2.2m or less, one of the others can be 2.8m or less, and the remaining one can be 12m or less. When going through the prescribed procedures such as an overloading permit, the width, length and height of the split units that are in the height direction when loaded onto a truck can be up to 3.55m.

In addition, in the above embodiment, the floor 10, ceiling 11, and wall 12 that form the room are respectively made of wooden laminated plate materials, but the floor 10, ceiling 11, and wall 12 are not limited to being made of wooden laminated plate materials, and various materials such as PC boards (precast concrete boards), tent materials, gypsum boards, plastic boards, and metal boards can be used. In this case, the floor 10, ceiling 11, and wall 12 can also be made of different types of materials.

Furthermore, the layout of the wooden house is not limited to the above and can be changed in various ways.

In addition, in the above embodiment, the room or building is an apartment building 100, but the building is not limited to the apartment building 100, and may be, for example, a detached house, a hospital, a hotel, a lodging facility, a nursing home, a dormitory, etc. Furthermore, the building is not limited to a permanent structure that is permanently installed in a specified location, but may be a temporary structure, such as a temporary housing unit that is temporarily installed in the event of a disaster.
