Description

The present invention relates to a room, a building, and a method for constructing a room.

Traditionally, buildings with rooms, such as detached houses, hospitals, hotels, lodging facilities, elderly care facilities, apartment buildings, temporary housing, dormitories, etc., have generally been constructed at the construction site using various building materials.

For example, Patent Document 1 describes a technology in which a wooden house, whose floor, ceiling and walls are made of laminated wooden boards such as CLT (Cross Laminated Timber), in which multiple wooden boards are laminated and glued together so that the grain directions are perpendicular to each other, is constructed with CLT to build the walls on a floor made of CLT, and then a ceiling made of CLT is placed on top of the walls to form a dwelling unit, and then multiple dwelling units are constructed on the left and right sides and on multiple floors using similar processes to form an apartment building.

The first end split unit 1B and the second end split unit 1C can be configured with the window 20 and the entrance door 21 pre-attached to the first end split wall 13B and the second end split wall 13C, respectively, but the window 20 and the entrance door 21 may be attached after the first end split unit 1B and the second end split unit 1C are connected to the intermediate split unit 1A.

In the wooden house 1, the first end side split unit 1B of the above configuration is connected to one side part SP1 of the intermediate split unit 1A of the above configuration, so that the dwelling unit 2 is defined between the partition wall 15 and the first end side wall 14B, and the second end side split unit 1C of the above configuration is connected to the other side part SP2 of the intermediate split unit 1A of the above configuration, so that the dwelling unit 3 is defined between the partition wall 15 and the second end side wall 14C.

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.

A method for constructing a wooden house according to one embodiment of the present invention includes an intermediate split unit manufacturing process in which an intermediate split unit 1A having the above-mentioned configuration is manufactured in a factory located at a different location from the construction site where the wooden house 1 to the apartment house 100 are constructed, an intermediate split unit transport process in which the intermediate split unit 1A manufactured in the factory is transported to the construction site, a first end side split unit manufacturing process in which a first end side split unit 1B having the above-mentioned configuration is manufactured in a factory located at a different location from the construction site where the wooden house 1 to the apartment house 100 are constructed, and a first end side split unit transport process in which the first end side split unit 1B manufactured in the factory is transported to the construction site. It includes a first end split unit transport process for transporting the unit to the construction site, a second end split unit production process for manufacturing the second end split unit 1C having the above-mentioned configuration in a factory located at a different location from the construction site where the wooden house 1 or apartment building 100 is constructed, a second end split unit transport process for transporting the second end split unit 1C manufactured in the factory to the construction site, and a connection process for connecting the first end split unit 1B to one side part SP1 of the intermediate split unit 1A transported to the construction site and connecting the second end split unit 1C to the other side part SP2.

In the intermediate division unit manufacturing process described above, the intermediate division unit 1A is manufactured by connecting the intermediate division floor section 10A, the intermediate division ceiling section 11A, and a pair of intermediate division end walls 13A, each of which is made of laminated wooden board (CLT), and by connecting a partition wall 15 between the pair of intermediate division end walls 13A. In addition, in the intermediate division unit manufacturing process, the interior of the intermediate division unit 1A can be finished by carrying out interior work, installation work for the storage space 28 and desk 29, electrical wiring work, etc.

In the intermediate division unit transport process, the intermediate division unit 1A manufactured in the intermediate division unit manufacturing process can be transported to the construction site, for example, by truck. When transporting by truck, it is preferable to protect the interior and exterior of the intermediate division unit 1A and the installed equipment, etc., as necessary.

In the above-mentioned first end split unit manufacturing process, the first end split unit 1B is manufactured by connecting the first end split floor section 10B, the first end split ceiling section 11B, a pair of first end split end walls 13B, and the first end side wall 14B, each of which is made of laminated wooden board (CLT). In addition, in the first end split unit manufacturing process, the interior of the first end split unit 1B can be finished by carrying out interior work, installation work for the kitchen 25, bathroom 26, toilet 27, and storage space 28, electrical wiring work, water supply and sewerage piping work, etc. It is preferable that the first end split unit manufacturing process is carried out in the same factory as the intermediate split unit manufacturing process, but it may be carried out in another factory.

In the first end side split unit transport process, the first end side split unit 1B manufactured in the first end side split unit manufacturing process can be transported to the construction site, for example, by truck. When transporting by truck, it is preferable to protect the interior and exterior of the first end side split unit 1B and the installed equipment, etc., as necessary.

Similarly, in the second end split unit manufacturing process, the second end split unit 1C is manufactured by connecting the second end split floor section 10C, the second end split ceiling section 11C, the pair of second end split end walls 13C, and the second end side wall 14C, each of which is made of laminated wooden board (CLT). In the second end split unit manufacturing process, the interior of the second end split unit 1C can be finished by carrying out interior work, installation work for the kitchen 25, bathroom 26, toilet 27, and storage space 28, electrical wiring work, water supply and sewerage piping work, etc. It is preferable that the second end split unit manufacturing process is carried out in the same factory as the intermediate split unit manufacturing process to the first end split unit manufacturing process, but it may be carried out in another factory.

In the second end side split unit transport process, the second end side split unit 1C manufactured in the second end side split unit manufacturing process can be transported to the construction site, for example, by truck. When transporting by truck, it is preferable to protect the interior and exterior of the second end side split unit 1C and the installed equipment, etc., as necessary.

In the above-mentioned connection process, the first end side split unit 1B transported to the construction site in the first end side split unit transport process is connected to one side part SP1 of the intermediate split unit 1A transported to the construction site in the intermediate split unit transport process, and the second end side split unit 1C transported to the construction site in the second end side split unit transport process is connected to the other side part SP2 of the intermediate split unit 1A. As described above, various configurations can be adopted for this connection, such as 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. In the connection process, the first end side split unit 1B and the second end side split unit 1C are connected to the intermediate split unit 1A, so that the wooden house 1 having the above-mentioned configuration can be constructed at the construction site.

In addition, by combining and connecting multiple wooden houses 1 constructed in the above connecting process with their intermediate dividing end walls 13A facing the same direction, a condominium 100 with multiple dwelling units can be constructed as shown in FIG. 2. In this case, a wooden house 1 may be constructed above or to the side of another wooden house 1 by connecting the first end side dividing unit 1B and the second end side dividing unit 1C to the intermediate dividing unit 1A above or to the side of an already constructed wooden house 1. Also, gaps may be provided between the wooden houses 1 to allow wiring, piping, etc. to be arranged.

In this way, in the wooden house 1, apartment building 100, and wooden house construction method of this embodiment, a wooden house 1 having two dwelling units 2, 3 can be constructed by connecting the first end side split unit 1B to one side SP1 of the intermediate split unit 1A and connecting the second end side split unit 1C to the other side SP2. Therefore, before constructing the wooden house 1 at the construction site, a wooden house 1 having two dwelling units 2, 3 can be easily constructed by simply connecting the intermediate split unit 1A, first end side split unit 1B, and second end side split unit 1C, which have been manufactured in a factory, at the construction site.

In addition, by combining multiple wooden houses 1 with the above configuration so that the intermediate dividing end walls 13A face in the same direction, the apartment building 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, the middle split unit 1A, the first end side split unit 1B, and the second end side split unit 1C are connected to each other to construct the wooden house 1. Therefore, before constructing the wooden house 1 at the construction site, the middle split unit 1A, the first end side split unit 1B, and the second end side split unit 1C can be finished in the factory by carrying out interior work, installation of the kitchen 25, bathroom 26, toilet 27, storage space 28, and desk 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 the middle split unit 1A, the first end side split unit 1B, and the second end side split unit 1C to each other 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 middle split unit 1A, first end side split unit 1B, and second end side split unit 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 intermediate split unit 1A, first end side split unit 1B, and second end side split unit 1C manufactured in a factory are connected at the construction site to construct the wooden house 1, so that the intermediate split unit 1A, first end side split unit 1B, and second end side split unit 1C manufactured in a 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 transport work compared to transporting the wooden house 1 as is.

In particular, in the wooden house 1, apartment building 100, and wooden house construction method of this embodiment, two dwelling units 2, 3 are formed by connecting three units, namely, the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C. Therefore, the wooden house 1 can be configured to have two dwelling units 2, 3 of the desired size, while the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C can each be made small to facilitate transportation.

In order to facilitate easy transportation of the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C from the factory to the construction site, it is preferable that the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C have external dimensions that are equal to or smaller than the limit size (width 2.2 m, height 2.8 m, length approximately 12 m) that can be transported by truck on Japanese roads without obtaining an overloading permit under the Road Traffic Act.

For example, the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C can have exterior sizes in which the widths WA, WB, and WC are each 2.2 m or less, the heights H are greater than 2.2 m and less than 2.8 m, and the lengths L are greater than 2.8 m and less than 12 m. In this case, the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C can have the same exterior sizes in which the widths WA, WB, and WC, the heights H, and the lengths L are the same. In the wooden house 1 of this embodiment, the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C have widths WA, WB, and WC of 2.2 m, lengths L of 6.0 m, and heights H of approximately 2.8 m. In this case, the width of the frontage of the two dwelling units 2 and 3 provided in the wooden house 1 of this embodiment is 3.2 m (2.2 m + 2.2 m/2).

Here, if a wooden house is an integrated structure that cannot be divided into multiple separate units, if the width of the entrance is 2.2 m or less, the height is 2.8 m or less, and the length is 12 m or less, the exterior dimensions are below the limit size, and it can be transported by truck without a permit for loading over the limit. However, if the width of the entrance exceeds 2.2 m, the exterior dimensions exceed the limit size, and it cannot be transported by truck without a permit for loading over the limit. Therefore, for integrated wooden houses, the width of the entrance is limited to 2.2 m or less, making it difficult to construct a structure with a dwelling unit with a width of 2.2 m or more.

In contrast, the wooden house 1 of this embodiment has two dwelling units 2 and 3 each having a width of 3.3 m, and therefore the overall width W exceeds the limit size, resulting in an external size that has a larger interior space or floor area than an integrated wooden house within the limit size. However, the intermediate split unit 1A, the first end split unit 1B, and the second end split unit 1C that constitute the wooden house 1 each have an external size with a width WA, WB, and WC of 2.2 m or less, a height H of more than 2.2 m and less than 2.8 m, and a length L of more than 2.8 m and less than 12 m, so that each can be loaded onto the loading platform 41 of the truck 40 within the limit size range. For example, as shown in FIG. 5, the intermediate split unit 1A can be loaded onto the loading platform 41 of the truck 40 within the limit size range with the intermediate split ceiling portion 11A facing upward and the pair of intermediate split end walls 13A facing forward and backward. Similarly, as shown in FIG. 6, the first end split unit 1B can be mounted within the limit size range on the bed 41 of the truck 40 with the first end split ceiling portion 11B facing upward and the pair of first end split end walls 13B facing in the fore-aft direction, and as shown in FIG. 7, the second end split unit 1C can be mounted within the limit size range on the bed 41 of the truck 40 with the second end split ceiling portion 11C facing upward and the pair of second end split end walls 13C facing in the fore-aft direction.

In this way, in the wooden house 1 of this embodiment, the intermediate split unit 1A, first end side split unit 1B, and second end side split unit 1C that constitute it have exterior dimensions of widths WA, WB, and WC of 2.2 m or less, heights H of more than 2.2 m and less than 2.8 m, and lengths L of more than 2.8 m and less than 12 m, so they can be transported from the factory to the construction site by truck 40 without an over-the-limit loading permit. This makes it even easier to transport the intermediate split unit 1A, first end side split unit 1B, and second end side split unit 1C by truck 40.

In addition, in the wooden house 1, apartment house 100, and wooden house construction method of this embodiment, the intermediate split unit 1A, the first end split unit 1B, and the second end split unit 1C are each designed to have exterior dimensions with widths WA, WB, and WC of 2.2 m or less, heights H of more than 2.2 m and less than 2.8 m, and lengths L of more than 2.8 m and less than 12 m. This allows the intermediate split unit 1A, the first end split unit 1B, and the second end split unit 1C to be transported from the factory to the construction site by truck 40 without an over-loading permit, while the two dwelling units 2 and 3 provided in the wooden house 1 each have a wide width of 2.2 m or more, thereby expanding the interior space or floor area.

Furthermore, in the wooden house 1, apartment building 100, and wooden house construction method of this embodiment, the three units of the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C are connected to form the two dwelling units 2, 3. Therefore, while the intermediate split unit 1A, the first end side split unit 1B, and the second end side split unit 1C are each sized to be transportable by truck 40, it is possible to construct a wooden house 1 having two dwelling units 2, 3 of the desired size, with a frontage width of 2.2 m or more, using a minimum number of split units.

Furthermore, in the wooden house 1, apartment building 100, and wooden house construction method of this embodiment, the frontage width WA of the middle split unit 1A, the frontage width WB of the first end split unit 1B, and the frontage width WC of the second end split unit 1C are all the same, so that the middle split unit 1A, the first end split unit 1B, and the second end split unit 1C each have an external size with the maximum frontage width that can be transported by truck 40, and by connecting the frontage width WA of the middle split unit 1A, the frontage width WB of the first end split unit 1B, and the second end split unit 1C, a wooden house 1 can be constructed with dwelling units 2 and 3 of the same size.

Figure 8 is a cross-sectional view of a wooden house as a modified room in plan view. Note that in Figure 8, the same reference symbols are used for the previously described components.

As shown in FIG. 3, in the wooden house 1, the partition wall 15 provided in the intermediate division unit 1A is shaped to extend straight from the center of the frontage width WA of one intermediate division end wall 13A to the center of the frontage width WA of the other intermediate division end wall 13A, but the shape of the partition wall 15 can be changed in various ways as long as it is configured to be provided between a pair of intermediate division end walls 13A and to divide the dwelling units 2 and 3. In this case, it is preferable that the partition wall 15 is configured to be capable of dividing the dwelling units 2 and 3 so that they are the same size.

For example, in the modified wooden house 4 shown in Figure 8, the partition 15 has a first partition portion 15a arranged parallel to the pair of intermediate partition end walls 13A at the midpoint between them, a second partition portion 15b extending straight from one end of one intermediate partition end wall 13A in the direction of the frontage width WA to one end of the first partition portion 15a in the direction of the frontage width WA, and a third partition portion 15c extending straight from the other end of the other intermediate partition end wall 13A in the direction of the frontage width WA to the other end of the first partition portion 15a in the direction of the frontage width WA. In this case, the kitchen 25, bathroom 26, and toilet 27 of one dwelling unit 2 are arranged between one intermediate dividing end wall 13A and the first partition wall portion 15a, and the kitchen 25, bathroom 26, and toilet 27 of the other dwelling unit 3 are arranged between the other intermediate dividing end wall 13A and the first partition wall portion 15a. In addition, the floor plans of dwelling unit 2 and dwelling unit 3 are arranged point-symmetrically with respect to each other, with the center of the first partition wall portion 15a in the direction of the frontage width WA as the center point.

The same effect as above can be obtained in a wooden house 1 having a partition wall 15 of this configuration.

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, the external dimensions of the intermediate split unit, first end split unit, and second end split unit that make up a wooden house are 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, the external dimensions can be changed in various ways within the following ranges: frontage width 2.2 m or less, height greater than 2.2 m and less than 2.8 m, and length greater than 2.8 m and less than 12 m. Note that if the required procedures, such as an overloading permit, are followed, the height of the split unit can be up to 3.55 m.

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.

The floor plan of the wooden house is not limited to the above and can be changed in various ways. The floor plan of dwelling unit 2 and the floor plan of dwelling unit 3 may be the same or different.

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.
