[Effects of the Invention]

[0020] According to the wooden unit house of the present invention, it is formed from a wood-based ceiling plate of a predetermined area that is formed into a roughly rectangular shape that is long in the front-to-back or width-to-back direction and extends horizontally, a wood-based floor plate of a predetermined area that is formed into a roughly rectangular shape that is long in the front-to-back or width-to-back direction and extends horizontally, and a wood-based wall panel of a predetermined area that is located between the wood-based ceiling plate and the wood-based floor plate and is formed into a roughly rectangular shape and extends vertically. Therefore, it is possible to create ceilings, walls, and floors with attractive designs (aesthetics) that wood-based materials possess, making it possible to create ceilings, walls, and floors that are aesthetically pleasing, and ceilings, walls, and floors that give residents and visitors the beauty, comfort, warmth, and tranquility that wood-based materials, which are natural materials, possess. Because the wooden unit house uses wood-based materials, which are sustainable and circular resources, it is possible to make effective use of forest resources and CO2 2 By contributing to the reduction of waste, the environmental burden can be reduced. Wooden unit houses define an internal living space of a predetermined volume that is long in the front-to-back or width-to-back direction, surrounded by wooden ceiling plates, wooden floor plates, and wooden wall panels. Therefore, it is possible to create a living space with ceilings, walls, and floors that can provide the beauty, comfort, warmth, and tranquility that natural wood materials offer. Wooden unit houses are transported to a predetermined installation site and erected there, so a house with a living space can be quickly built in a predetermined location without requiring much effort or time.

[0021] A wooden unit house is formed by a wooden first wall panel and a wooden second wall panel that are spaced apart and opposed in the front-rear direction and extend in the width direction, and a wooden third wall panel that is located between the first side edge portions of the wooden first wall panel and the wooden second wall panel and extends in the front-rear direction. The wooden unit house having a first opening space that is located on the opposite side of the width direction of the wooden third wall panel and has substantially the same area as the wooden third wall panel can be made into a wall with an attractive design (pattern) of the wooden (wood) material by the wooden wall panel formed by the wooden first wall panel, the wooden second wall panel, and the wooden third wall panel, and a wall with a good viewing field can be made. At the same time, a unit house with a wall that gives the residents and visitors the beauty, comfort, warmth, and tranquility of the wooden material, which is a natural material, can be made. The wooden unit house can be connected to other wooden unit houses on the side of its first opening space to form a house with a large-volume living space formed by a plurality of wooden unit houses.

[0022] In the wooden unit house, the first side edge portion extending in the vertical direction of the wooden first wall panel is connected to the first side edge portion extending in the vertical direction of the wooden third wall panel by a predetermined connecting means, and the first side edge portion extending in the vertical direction of the wooden second wall panel is connected to the second side edge portion extending in the vertical direction of the wooden third wall panel by a predetermined connecting means. By the mutually connected wooden first wall panel, wooden second wall panel, and wooden third wall panel, a wall with an attractive design (pattern) of the wooden (wood) material can be made, and a wall with a good viewing field can be made. At the same time, a unit house with a wall that gives the residents and visitors the beauty, comfort, warmth, and tranquility of the wooden material, which is a natural material, can be made.

[0023] A wooden unit house is formed by a wooden first wall panel and a wooden second wall panel that are spaced apart from each other in the front-rear direction and extend in the width direction, and a wooden fourth wall panel that is located between the second side edge of the first wall panel and the second side edge of the wooden second wall panel and extends in the front-rear direction. The wooden unit house having a second opening space that is located on the opposite side in the width direction of the wooden fourth wall panel and has substantially the same area as the wooden fourth wall panel can be made into a wall with an attractive design (pattern) of the wooden (wood) material by the wooden wall panel formed by the wooden first wall panel, the wooden second wall panel, and the wooden fourth wall panel, and a wall with a good viewing field can be made. At the same time, a unit house with a wall that gives the beauty, comfort, warmth, and tranquility of the wooden material, which is a natural material, to the residents and visitors can be made. The wooden unit house can be connected to another wooden unit house on the side of its second opening space to form a house with a large-volume living space formed by a plurality of wooden unit houses.

[0024] In the wooden unit house, the second side edge extending in the vertical direction of the first wall panel is connected to the first side edge extending in the vertical direction of the fourth wall panel by a predetermined connecting means, and the second side edge extending in the vertical direction of the second wall panel is connected to the second side edge extending in the vertical direction of the fourth wall panel by a predetermined connecting means. A wall with an attractive design (pattern) of the wooden (wood) material can be made by the mutually connected wooden first wall panel, wooden second wall panel, and wooden fourth wall panel, and a wall with a good viewing field can be made. At the same time, a unit house with a wall that gives the beauty, comfort, warmth, and tranquility of the wooden material, which is a natural material, to the residents and visitors can be made.

[0025] A wooden unit house is formed from wooden wall panels, consisting of a first wooden wall panel and a second wooden wall panel that are spaced apart in the front-to-back direction and extend in the width direction. The unit house has a first opening space of a predetermined area located between the first side edge of the first wooden wall panel and the first side edge of the second wooden wall panel, and a second opening space of a predetermined area located between the second side edge of the first wooden wall panel and the second side edge of the second wooden wall panel, spaced apart in the width direction from the first opening space. This allows for walls with attractive designs (aesthetics) that are inherent to wooden (wood) materials, creating visually appealing walls, and also allows for the creation of a unit house equipped with walls that provide residents and visitors with the beauty, comfort, warmth, and tranquility that natural wooden materials offer. By connecting other wooden unit houses to the sides of the first and second opening spaces, it is possible to create a house with a large volume of living space formed from multiple wooden unit houses.

[0026] Wooden unit houses, in which the wood-frame ceiling plates and floor plates are made from CLT and the wood-frame wall panels are made from 2x4 lumber, can have attractive designs for the ceilings, walls, and floors made from CLT and 2x4 lumber, creating visually appealing ceilings, walls, and floors, while also providing residents and guests with the beauty, comfort, warmth, and tranquility that natural materials like CLT and 2x4 lumber offer. Because wooden unit houses utilize sustainable, circular resources like CLT and 2x4 lumber, they effectively utilize forest resources and reduce CO2 emissions. 2By contributing to the reduction of waste, the environmental burden can be reduced. Wooden unit houses define an internal living space of a predetermined volume that is long in the front-to-back or width-to-back direction, surrounded by wood-based ceiling plates and wood-based floor plates made from CLT and wood-based wall panels made from 2x4 lumber. Therefore, it is possible to create a living space with ceilings, walls, and floors that can provide the beauty, comfort, warmth, and tranquility that natural materials such as CLT and 2x4 lumber possess. Because the wood-based ceiling plates and wood-based floor plates of wooden unit houses are made from CLT, sturdy ceilings and sturdy floors can be made, and sturdy unit houses can be made.

[0027] In a wooden unit house, where a predetermined insulation material is installed from the outside of the wooden wall panel in a storage space surrounded by the upper and lower frames, first and second vertical frames, and their studs, despite being internally insulated, the insulation material is installed in the storage space from the outside of the wooden wall panel. As a result, electrical equipment such as wiring cables, outlet boxes, and outlet plates, plumbing equipment such as water supply and drainage pipes, and air conditioning equipment such as piping and ducts, which are located in the storage space of the wooden wall panel, do not get in the way when installing the insulation material. The insulation material can be smoothly installed in the storage space surrounded by the upper and lower frames, first and second vertical frames, and their studs, and a wooden unit house with internal insulation can be quickly constructed without requiring much effort or time.

[0028] In a wooden unit house in which a predetermined exterior wall finishing material and a predetermined waterproofing material are installed on the outer end faces of the upper and lower frames, the first and second vertical frames and their studs, which contain insulation material in a storage space, the exterior wall finishing material and waterproofing material are installed on the outer end faces of the upper and lower frames, the first and second vertical frames and their studs after the internal insulation has been created. This allows for quick waterproofing of the wood-based wall panels and rapid attachment of the exterior wall finishing material to the wood-based wall panels, enabling the rapid construction of a unit house with waterproofing and exterior walls without requiring much time or effort.

[0029] In a wooden unit house where the designated connecting means is a hold-down connector, and the edge of a wood-frame ceiling plate made from CLT is connected to the upper end of a wood-frame wall panel made from 2x4 lumber by the hold-down connector, and the edge of a wood-frame floor plate made from CLT is connected to the lower end of a wood-frame wall panel made from 2x4 lumber by the hold-down connector, the wood-frame ceiling plate made from CLT and the wood-frame wall panel made from 2x4 lumber can be reliably and strongly connected by using the hold-down connector to connect the edge of the wood-frame ceiling plate to the upper end of the wood-frame wall panel, and the edge of the wood-frame floor plate to the lower end of the wood-frame wall panel, and the wood-frame ceiling plate made from CLT and the wood-frame wall panel made from 2x4 lumber can be reliably and strongly connected, and the wood-frame floor plate made from CLT and the wood-frame wall panel made from 2x4 lumber can be reliably and strongly connected, making it possible to create a sturdy unit house.

[0030] In a wooden unit house where the predetermined connecting means are vertical screws and diagonal screws, and the edge of a wood-frame ceiling plate made from CLT and the upper end of a wood-frame wall panel made from 2x4 lumber are connected by at least one of the diagonal screws, and the edge of a wood-frame floor plate made from CLT and the lower end of a wood-frame wall panel made from 2x4 lumber are connected by at least one of the diagonal screws, the wood-frame ceiling plate made from CLT and the wood-frame wall panel made from 2x4 lumber can be reliably and firmly connected, and the wood-frame floor plate made from CLT and the wood-frame wall panel made from 2x4 lumber can be reliably and firmly connected, and a sturdy unit house can be made.

[0031] In a wooden unit house where a wood-based floor plate made from CLT is connected to a sill plate laid on a foundation rise constructed at the installation site by at least diagonal screws, the wood-based floor plate made from CLT can be securely and firmly connected to the sill plate laid on the foundation rise by using at least diagonal screws, thereby creating a sturdy unit house.

[0033] The details of the wooden unit house according to the present invention will be explained below, referring to the attached drawings such as Figure 1, which is a perspective view of the wooden unit house 10A shown as an example. Figure 2 is a perspective view of the wooden unit house 10A of Figure 1 shown from the rear, and Figure 3 is a front view of the wooden unit house 10A of Figure 1. Figure 4 is a rear view of the wooden unit house 10A of Figure 1, and Figure 5 is a top view of the wooden unit house 10A of Figure 1. Figure 6 is a bottom view of the wooden unit house 10A of Figure 1. In Figure 1, the wooden unit house 10A is shown from the front. In Figures 1 and 2, the vertical direction is indicated by arrow X, the front-to-back direction by arrow Y, and the width direction by arrow Z.

[0034] The wooden unit houses 10A (including the wooden unit houses 10B and 10C described later) are assembled at the assembly plant, then transported to the designated installation site by a predetermined means of transport, and erected at the installation site. By combining wooden unit houses 10A, 10B, and 10C and erecting them at the installation site, wooden unit houses 63 with various floor plans (see Figure 28) are created. Transport vehicles, railways, and ships are used as means of transport.

[0035] The wooden unit house 10A is formed from a wood-based ceiling plate 11a of a predetermined area that unfolds horizontally, a wood-based floor plate 12a of a predetermined area that unfolds horizontally, and a wood-based wall panel 13 of a predetermined area that unfolds vertically. The wood-based ceiling plate 11a is made from CLT (Cross Laminated Timber) which is formed by arranging sawn boards (laminae) and then laminating and bonding them together with an adhesive (water-based polymer isocineate resin adhesive (non-formaldehyde adhesive)) so that the fiber directions are perpendicular to each other.

[0036] CLT can be constructed using any of the following configurations: 3 layers / 3 plies, 3 layers / 4 plies, 5 layers / 5 plies, 5 layers / 7 plies, 7 layers / 7 plies, or 9 layers / 9 plies. CLT can be made from various materials, including cedar CLT panels, cypress CLT panels, larch CLT panels, and fir CLT panels. CLT offers excellent thermal insulation, high energy efficiency, superior seismic resistance, and is lighter than reinforced concrete. Furthermore, any type of CLT developed in the future can be used.

[0037] The wood-based ceiling plate 11a is formed into a substantially rectangular shape that is long in the front-to-back direction and has first and second edge portions 14, 15 that extend in the width direction and third and fourth edge portions 16, 17 that extend in the front-to-back direction. Alternatively, the wood-based ceiling plate 11a may be formed into a substantially rectangular shape that is long in the width direction. In this case, the wood-based ceiling plate 11a has first and second edge portions 14, 15 that extend in the front-to-back direction and third and fourth edge portions 16, 17 that extend in the width direction.

[0038] Multiple rafters 18 are arranged on the upper surface of the wood-based ceiling plate 11a, extending in the width direction at equal intervals in the front-to-back direction. Sheathing plywood 19 is attached to the upper surfaces of these rafters 18. The rafters 18 and sheathing plywood 19 are fixed to the wood-based ceiling plate 11a (CLT) with long screws (not shown). Waterproofing 20 is applied to the upper surface of the sheathing plywood. Waterproofing 20 is a film waterproofing (FRP waterproofing) applied by mixing the main agent and hardener and spreading it during application. Alternatively, sheet waterproofing (PVC sheet waterproofing) can be used as waterproofing 20, in which a PVC sheet is fixed to the sheathing plywood (substrate) with adhesive or fixing screws.

[0039] The wood-based floor plate 12a, like the wood-based ceiling plate 11a, is made from CLT. The wood-based floor plate 12a is formed into a substantially rectangular shape that is long in the front-to-back direction and has first and second edge portions 21, 22 that extend in the width direction and third and fourth edge portions 23, 24 that extend in the front-to-back direction. Alternatively, the wood-based floor plate 12a may be formed into a substantially rectangular shape that is long in the width direction. In this case, the wood-based floor plate 12a has first and second edge portions 21, 22 that extend in the front-to-back direction and third and fourth edge portions 23, 24 that extend in the width direction.

[0040] Flooring 25 is installed on the top surface of the wood-based floor plate 12a (CLT). The flooring 25 (sound-insulating wood flooring material with a special cushioning material to enhance sound insulation performance) is bonded to the top surface of the wood-based floor plate 12a (CLT) with adhesive. Alternatively, a joist method can be used in which multiple joists are placed on the top surface of the wood-based floor plate 12a (CLT), the flooring is laid perpendicular to the joists, and the flooring is fixed to the joists using adhesive and nails.

[0041] The wooden wall panel 13 is formed from a first wooden wall panel 13a with a predetermined area extending in the width direction (or front-to-back direction), a second wooden wall panel 13b with a predetermined area extending in the width direction (or front-to-back direction), and a third wooden wall panel 13c with a predetermined area extending in the front-to-back direction (or width direction). The first wooden wall panel 13a to the third wooden wall panel 13c are made using the two-by-four construction method with two-by-four lumber and are formed into a roughly rectangular shape. The two-by-four construction method is specified in detail, from the size, usage method, and location of the two-by-four lumber (structural material), nails, and hardware, to the construction procedure, and is manualized in the Specifications for Construction of Framed Wall Construction Housing (supervised by the Japan Housing Finance Agency), etc. Therefore, it is less dependent on the skill of the builder and can achieve uniform quality and performance.

[0042] CLT and 2x4 lumber utilize wood, a renewable and cyclical resource, as a structural material, and their use allows for the effective utilization of sustainable wood resources. CLT and 2x4 lumber are building materials with a lower environmental impact, as they require less energy and CO2 emissions in their manufacturing process compared to materials such as iron and concrete. The wood that makes up CLT and 2x4 lumber is the only natural resource that can be reproduced through planned logging and reforestation, thus ensuring its continued use indefinitely.

[0043] Furthermore, in managed forests (economic forests), healthy forests can be regenerated by systematically logging and replanting. Using CLT or 2x4 lumber as building materials means absorbing and sequestering CO2 from the atmosphere and storing it within the building, which plays the same role as a forest. Creating a stock of long-lasting wooden houses means having another forest in the city, which also contributes to environmental conservation.

[0044] The first wooden wall panel 13a to the third wooden wall panel 13c are formed from a top joint 26 (square timber) and an upper frame 27 (square timber) extending in the front-to-back direction or width direction, a lower frame 28 (square timber) located below the upper frame 27 in the vertical direction and extending in the front-to-back direction or width direction, a first vertical frame 29 (square timber) located between the upper and lower frames 27 and 28 and extending in the vertical direction, a second vertical frame 30 (square timber) extending in the vertical direction from the first vertical frame 29, spaced apart in the front-to-back direction or width direction and facing each other, and a plurality of studs 31 (square timber) located between the first and second vertical frames 29 and 30, extending in the vertical direction and spaced apart in the front-to-back direction or width direction.

[0045] The head joints 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, and studs 31 are connected by standardized nails. The wood-based first wall panels 13a to the third wall panels 13c are assembled from 2x4 lumber (head joints 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, and studs 31) to create a "framework" and form a highly rigid diaphragm.

[0046] The first wooden wall panel 13a has a first upper end portion 32 (head joint 26 and upper frame 27) extending in the width direction (or front-to-back direction), a first lower end portion 33 (lower frame 28) located below the first upper end portion 32 in the vertical direction and extending in the width direction (or front-to-back direction), a first side edge portion 34 (first vertical frame 29) extending vertically from the first upper end portion 32 toward the first lower end portion 33, and a second side edge portion 35 (second vertical frame 30) extending vertically from the first upper end portion 32 toward the first lower end portion 33 and spaced apart from the first side edge portion 34 in the width direction (or front-to-back direction). Various shapes of window frames (sashes) and door frames can be made from the first wooden wall panel 13a.

[0047] The second wooden wall panel 13b is positioned opposite the first wooden wall panel 13a at a distance in the front-to-back direction (or width direction). The second wooden wall panel 13b has a second upper end portion 36 (head joint 26 and upper frame 27) extending in the width direction (or front-to-back direction), a second lower end portion 37 (lower frame 28) located below the second upper end portion 36 in the vertical direction and extending in the width direction (or front-to-back direction), a first side edge portion 38 (first vertical frame 29) extending vertically from the second upper end portion 36 toward the second lower end portion 37, and a second side edge portion 39 (second vertical frame 30) extending vertically from the second upper end portion 36 toward the second lower end portion 37 and positioned opposite the first side edge portion 38 at a distance in the width direction (or front-to-back direction). Various shapes of window frames (sashes) and door frames are made from the second wooden panel 13b.

[0048] The third wooden wall panel 13c is located between the first side edge 34 of the first wooden wall panel 13a and the first side edge 38 of the second wooden wall panel 13b. The third wooden wall panel 13c has a third upper end portion 40 (head joint 26 and upper frame 27) extending in the front-rear direction (or width direction), a third lower end portion 41 (lower frame 28) located below the third upper end portion 40 in the vertical direction and extending in the front-rear direction (or width direction), a first side edge portion 42 (first vertical frame 29) extending vertically from the third upper end portion 40 toward the third lower end portion 41, and a second side edge portion 43 (second vertical frame 30) extending vertically from the third upper end portion 40 toward the third lower end portion 41 and spaced apart from the first side edge portion 42 in the width direction (or front-rear direction). Various shapes of window frames (sashes) are made on the third wooden panel 13c. Although not shown in the illustration, electrical equipment such as wiring cables, outlet boxes, and outlet plates, plumbing equipment such as water supply and drainage pipes, and air conditioning equipment such as piping and ducts are installed on the first to third wooden wall panels 13a to 13c, and holes for ventilation openings and refrigerant pipes and drain hoses for air conditioners are drilled.

[0053] In the panel-plate connection process, the second upper end portion 36 (head joint 26 and upper frame 27) of the second wooden wall panel 13b is connected to the second edge portion 15 of the wooden ceiling plate 11a by hold-down hardware 65 (tension hardware) (predetermined connection means), and the second upper end portion 36 is connected to the second edge portion 14 by at least one of the vertical screws 61 (vertical screws) and diagonal screws 62 (diagonal screws) (predetermined connection means), specifically the diagonal screws 62.

[0054] The second lower end portion 37 (lower frame) of the second wooden wall panel 13b is connected to the second edge portion 22 of the wooden floor plate 12a by a hold-down fitting 65 (tension fitting) (predetermined connecting means), and the second lower end portion 37 is connected to the second lower end portion 22 by at least one of the vertical screws 61 (vertical screws) and diagonal screws 62 (diagonal screws) (predetermined connecting means), specifically the diagonal screws 62. The second upper end portion 36 of the second wooden wall panel 13b and the second edge portion 15 of the wooden ceiling plate 11a are firmly connected by hold-down fittings 65, vertical screws 61, and diagonal screws 62, and the second lower end portion 37 of the second wooden wall panel 13b and the second edge portion 22 of the wooden floor plate 12a are firmly connected by hold-down fittings 65, vertical screws 61, and diagonal screws 62.

[0055] Furthermore, the third upper end portion 40 (head joint 26 and upper frame 27) of the third wooden wall panel 13c is connected to the third end edge portion 16 of the wooden ceiling plate 11a by a hold-down fitting 65 (tension fitting) (predetermined connecting means), and the third upper end portion 40 is connected to the third end edge portion 16 by at least one of the vertical screws 61 (vertical screws) and diagonal screws 62 (diagonal screws) (predetermined connecting means), specifically the diagonal screws 62.

[0056] The third lower end portion 41 (lower frame 28) of the third wooden wall panel 13c is connected to the third edge portion 23 of the wooden floor plate 12a by a hold-down fitting 65 (tension fitting) (predetermined connecting means), and the third lower end portion 41 is connected to the third lower end portion 23 by at least one of the vertical screws 61 (vertical screws) and diagonal screws 62 (diagonal screws) (predetermined connecting means), specifically the diagonal screws 62. The third upper end portion 40 of the third wooden wall panel 13c and the third edge portion 16 of the wooden ceiling plate 11a are firmly connected by hold-down fittings 65, vertical screws 61, and diagonal screws 62, and the third lower end portion 41 of the third wooden wall panel 13c and the third edge portion 23 of the wooden floor plate 12a are firmly connected by hold-down fittings 65, vertical screws 61, and diagonal screws 62.

[0057] In the panel-to-panel connection process shown in Figure 7, the first side edge 34 (first vertical frame 29) of the first wooden wall panel 13a is connected to the first side edge 42 (first vertical frame 29) of the third wooden wall panel 13c by long screws (predetermined connecting means) (not shown), and the first side edge 38 (first vertical frame 29) of the second wooden wall panel 13b is connected to the second side edge 43 (second vertical frame) of the third wooden wall panel 13c by long screws (predetermined connecting means) (not shown). The first side edge 34 of the first wooden wall panel 13a and the first side edge 42 of the third wooden wall panel 13c are firmly connected by long screws, and the first side edge 38 of the second wooden wall panel 13b and the second side edge 43 of the third wooden wall panel 13c are firmly connected by long screws.

[0058] After the panel-plate connection process and the panel-panel connection process, the interior wall finishing material installation process and the insulation material installation process shown in Figure 8 are carried out. The interior wall finishing material installation process installs the interior wall finishing material 45 onto the first wood-based wall panels 13a to the third wood-based wall panels 13c, and after the interior wall finishing material installation process, the insulation material installation process installs the insulation material 46 onto the first to third wood-based wall panels 13a to 13c. Plasterboard with fire resistance and sound insulation properties is used for the interior wall finishing material 45. Glass wool or cellulose fiber is used for the insulation material 46. Note that wallpaper, painted walls, decorative plywood, tiles, etc. can also be used as the interior wall finishing material.

[0059] In the interior wall finishing material installation process, the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end faces of the first wooden wall panel 13a (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown), the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end faces of the second wooden wall panel 13b (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown), and the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end faces of the third wooden wall panel 13c (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown).

[0060] In the insulation material installation process, insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the first installation space 47 (installation space) of the first wooden wall panel 13a surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31; insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the second installation space 48 (installation space) of the second wooden wall panel 13b surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31; and insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the third installation space 49 (installation space) of the third wooden wall panel 13c surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31.

[0061] The insulation material 46 is installed in the first to third storage spaces 47 to 49 from the exterior side (outside of the wooden unit house 10A) of the first to third wooden wall panels 13a to 13c. In the first to third wooden wall panels 13a to 13c, the insulation material 46 is installed in the first to third storage spaces 47 to 49 from the exterior side of these panels 13a to 13c, forming internal insulation.

[0062] After the interior wall finishing material installation process and the insulation material installation process, the waterproofing process and exterior wall finishing material installation process shown in Figure 9 are carried out. In the waterproofing process, a breathable waterproof sheet 50 is installed on the first wood-based wall panel 13a to the third wood-based wall panel 13c. After the waterproofing process, the exterior wall finishing material installation process installs the exterior wall finishing material 51 on the first to third wood-based wall panels 13a to 13c. Siding material is used for the exterior wall finishing material 51. In addition, any of the following can be used for the siding material: wood-based siding, resin-based siding, metal-based siding, or ceramic-based siding. Furthermore, mortar, tiles, or ALC can also be used as the exterior wall finishing material 51.

[0063] In the waterproofing process, a breathable waterproof sheet 50 of approximately the same size as the first wooden wall panel 13a (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31), which contains insulation material 46 in the first containment space 47, is attached to the outer end surface of the first wooden wall panel 13a, and a second wooden wall panel 13b (head joint 26, upper frame 27, lower frame 28, first vertical frame), which contains insulation material 46 in the second containment space 48 A breathable waterproof sheet 50, approximately the same size as the second wooden wall panel 13b, is attached to the outer end surface of the second wooden wall panel 13b (29, second vertical frame 30, studs 31), and a breathable waterproof sheet 50, approximately the same size as the third wooden wall panel 13c, is attached to the outer end surface of the third wooden wall panel 13c (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, studs 31), which houses the insulation material 46 in the third storage space 49.

[0064] In the exterior wall finishing material installation process, the exterior wall finishing material 51 (siding material) is joined (fixed) to the outer end surface of the first wooden wall panel 13a (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) to which the breathable waterproof sheet 50 is attached, using screws (not shown). The exterior wall finishing material 51 (siding material) is joined (fixed) to the outer end faces of the second vertical frame 30 and studs 31 using screws (not shown), and the exterior wall finishing material 51 (siding material) is joined (fixed) to the outer end faces of the third wooden wall panel 13c (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, studs 31) to which the breathable waterproof sheet 50 is attached using screws (not shown). Upon completion of each step, the semi-finished wooden unit house 10A is completed. The wooden unit house 10A has a first opening space 52 located on the opposite side in the width direction of the third wooden wall panel 13c and having approximately the same area as the third wooden wall panel 13c.

[0065] The wooden unit house 10A is formed from wood-based ceiling plates 11a and wood-based floor plates 11b made from CLT, and wood-based first wall panels 13a to third wall panels 13c made from 2x4 lumber. This allows the forces of earthquakes and vibrations to be evenly distributed throughout the wooden unit house 10A without concentrating them at a single point, thus preventing deformation, damage, and collapse of the wooden unit house 10A due to earthquakes and vibrations.

[0066] The wooden unit house 10A can create attractive ceilings and floors with appealing designs by utilizing wood-based ceiling plates 11a and wood-based floor plates 11b made from CLT, and attractive walls with appealing designs by utilizing wood-based first wall panels 13a to third wall panels 13c made from 2x4 lumber, thereby creating ceilings, walls, and floors that provide residents and visitors with the beauty, comfort, warmth, and tranquility that natural wood materials offer.

[0067] The wooden unit house 10A defines an internal living space 44 with a predetermined volume that is long in the front-to-back direction (or width direction), surrounded by a wooden ceiling plate 11a, a wooden floor plate 12a, and wooden first wall panels 13a to third wall panels 13c. Therefore, it is possible to create a living space 44 equipped with a ceiling, walls, and floor that can provide the beauty, comfort, warmth, and tranquility that natural wood materials offer. The wooden unit house 10A makes extensive use of wood materials, which are sustainable and circular resources, thus effectively utilizing forest resources and reducing CO2 emissions. 2 By contributing to the reduction of [unspecified factor], the environmental burden can be reduced.

[0068] In the wooden unit house 10A, insulation material 46 (glass wool or cellulose fiber) is installed in the first to third storage spaces 47 to 49 from the outside of the wooden first wall panel 13a to the wooden third wall panel 13c, forming internal insulation. Despite being internal insulation, because the insulation material is installed in the first to third storage spaces 47 to 49 from the outside of the wooden first to third wall panels 13a to 13c, electrical equipment such as wiring cables, outlet boxes, outlet plates, plumbing equipment such as water supply and drainage pipes, and air conditioning equipment such as piping and ducts located in the first to third storage spaces 47 to 49 of the wooden first to third wall panels 13a to 13c do not get in the way when installing the insulation material. This allows the insulation material 46 to be installed smoothly in the first to third storage spaces 47 to 49, and the wooden unit house 10A with internal insulation created by the insulation material 46 can be quickly constructed without requiring much effort or time.

[0069] In the wooden unit house 10A, the ceiling and floor are formed by wood-based ceiling plates 11a and wood-based floor plates 11b made from CLT, and the walls are formed by wood-based first wall panels 13a to third wall panels 13c made using a standardized two-by-four construction method. By connecting the wood-based ceiling plate 11a, wood-based floor plate 12a, and wood-based first to third wall panels 13a to 13c according to a predetermined procedure, the wooden unit house 10A can be constructed easily and quickly by a contractor following the manual without relying on the superior skills of a skilled worker, and a wooden unit house 10A with uniform quality and high strength can be easily produced.

[0070] Figure 10 is a perspective view of wooden unit house 10B, shown as another example, and Figure 11 is a perspective view of wooden unit house 10B from the rear. Figure 12 is a front view of wooden unit house 10B from Figure 10, and Figure 13 is a rear view of wooden unit house 10B from Figure 10. In Figure 10, wooden unit house 10B is shown from the front. In Figures 10 and 11, the vertical direction is indicated by arrow X, the front-to-back direction by arrow Y, and the width direction by arrow Z. Note that the top and bottom views of wooden unit house 10B are the same as the top view of wooden unit house 10A shown in Figure 5 and the bottom view of wooden unit house 10A shown in Figure 6, so Figures 5 and 6 are used as a reference and the illustration of the top and bottom views of wooden unit house 10B is omitted.

[0071] The wooden unit house 10B is formed from a wood-based ceiling plate 11b of a predetermined area that unfolds horizontally, a wood-based floor plate 12b of a predetermined area that unfolds horizontally, and a wood-based wall panel 13 of a predetermined area that unfolds vertically. The wood-based ceiling plate 11b and the wood-based floor plate 12b are made from CLT (Cross Laminated Timber), similar to those of the wooden unit house 10A.

[0072] The wood-frame ceiling plate 11b of the wooden unit house 10B is formed into a roughly rectangular shape that is long in the front-to-back direction and has first and second end portions 14, 15 that extend in the width direction and third and fourth end portions 16, 17 that extend in the front-to-back direction. Alternatively, the wood-frame ceiling plate 11b may be formed into a roughly rectangular shape that is long in the width direction, in which case the wood-frame ceiling plate 11b has first and second end portions 14, 15 that extend in the front-to-back direction and third and fourth end portions 16, 17 that extend in the width direction. Multiple rafters 18 that extend in the width direction at equal intervals in the front-to-back direction are arranged on the upper surface of the wood-frame ceiling plate 11b, and roof sheathing plywood 19 is attached to the upper surface of these rafters 18. These rafters 18 and roof sheathing plywood 19 are fixed to the wood-frame ceiling plate 11b (CLT) with long screws (not shown). The top surface of the roof sheathing plywood 19 is coated with waterproofing 20 (film waterproofing (FRP waterproofing)).

[0073] The wooden floor plate 12b of the wooden unit house 10B is formed into a roughly rectangular shape that is long in the front-to-back direction and has first and second edge portions 21, 22 that extend in the width direction and third and fourth edge portions 23, 24 that extend in the front-to-back direction. Alternatively, the wooden floor plate 12b may be formed into a roughly rectangular shape that is long in the width direction, in which case the wooden floor plate 12b has first and second edge portions 21, 22 that extend in the front-to-back direction and third and fourth edge portions 23, 24 that extend in the width direction. Flooring 26 (sound-insulating wooden flooring material with a special cushioning material to enhance sound insulation performance) is bonded to the upper surface of the wooden floor plate 12b (CLT) with adhesive.

[0074] The wooden wall panel 13 is formed from a first wooden wall panel 13d with a predetermined area extending in the width direction (or front-to-back direction), a second wooden wall panel 13e with a predetermined area extending in the width direction (or front-to-back direction), and a fourth wooden wall panel 13f with a predetermined area extending in the front-to-back direction (or width direction). The first wooden wall panel 13d, the second wooden wall panel 13e, and the fourth wooden wall panel 13f are made using the two-by-four construction method with two-by-four lumber, similar to the first wooden wall panels 13a to the third wooden wall panels 13c, and are formed into a roughly rectangular shape.

[0075] The first wooden wall panel 13d, the second wooden wall panel 13e, and the fourth wooden wall panel 13e are formed from a top joint 26 (square timber) and an upper frame 27 (square timber) extending in the front-to-back direction or width direction, a lower frame 28 (square timber) located vertically below the upper frame 27 and extending in the front-to-back direction or width direction, a first vertical frame 29 (square timber) located between the upper and lower frames 27 and 28 and extending in the vertical direction, a second vertical frame 30 (square timber) extending vertically from the first vertical frame 29, spaced apart in the front-to-back direction or width direction and facing each other, and a plurality of studs 31 (square timber) located between the first and second vertical frames 29 and 30, extending vertically and spaced apart in the front-to-back direction or width direction.

[0076] The head joints 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, and studs 31 are connected by standardized nails. The first wood-frame wall panel 13d, the second wood-frame wall panel 13e, and the fourth wood-frame wall panel 13f are assembled from 2x4 lumber (head joints 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, and studs 31) to create a "framework" that forms a highly rigid diaphragm.

[0077] The first wooden wall panel 13d has a first upper end portion 32 (head joint 26 and upper frame 27) extending in the width direction (or front-to-back direction), a first lower end portion 33 (lower frame 28) located below the first upper end portion 32 in the vertical direction and extending in the width direction (or front-to-back direction), a first side edge portion 34 (first vertical frame 29) extending in the vertical direction, and a second side edge portion 35 (second vertical frame 30) extending in the vertical direction, spaced apart from the first side edge portion 34 in the width direction (or front-to-back direction). Various shapes of window frames (sashes) and door frames can be made from the first wooden wall panel 13d.

[0078] The second wooden wall panel 13e is positioned opposite the first wooden wall panel 13d, spaced apart in the front-to-back direction (or width direction). The second wooden wall panel 13e has a second upper end portion 36 (head joint 26 and upper frame 27) extending in the width direction (or front-to-back direction), a second lower end portion 37 (lower frame 28) located below the second upper end portion 36 in the vertical direction and extending in the width direction (or front-to-back direction), a first side edge portion 38 (first vertical frame 29) extending in the vertical direction, and a second side edge portion 39 (second vertical frame 30) extending in the vertical direction, spaced apart from the first side edge portion 38 in the width direction (or front-to-back direction).

[0089] After the panel-plate connection process and the panel-panel connection process, the interior wall finishing material installation process and the insulation material installation process shown in Figure 15 are carried out. The interior wall finishing material installation process installs the interior wall finishing material 45 onto the first wood-based wall panel 13d, the second wood-based wall panel 13e, and the fourth wood-based wall panel 13f. After the interior wall finishing material installation process, the insulation material installation process installs the insulation material 46 onto the first wood-based wall panel 13d, the second wood-based wall panel 13e, and the fourth wood-based wall panel 13f. Plasterboard with fire resistance and sound insulation properties is used for the interior wall finishing material 45. Glass wool or cellulose fiber is used for the insulation material 46.

[0090] In the interior wall finishing material installation process, the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end face of the first wooden wall panel 13d (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown), the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end face of the second wooden wall panel 13e (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown), and the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end face of the fourth wooden wall panel (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown).

[0091] In the insulation material installation process, insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the first installation space 47 (installation space) of the first wooden wall panel 13d surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31; insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the second installation space 48 (installation space) of the second wooden wall panel 13e surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31; and insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the fourth installation space 57 (installation space) of the fourth wooden wall panel 13f surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31.

[0092] The insulation material 46 is installed in the first storage space 47, second storage space 48, and fourth storage space 49 from the exterior side (outside of the wooden unit house 10B) of the first wooden wall panel 13d, second wooden wall panel 13e, and fourth wooden wall panel 13f. In the first wooden wall panel 13d, second wooden wall panel 13e, and fourth wooden wall panel 13f, the insulation material 46 is installed in the first storage space 47, second storage space 48, and fourth storage space 49 from the exterior of those panels 13d to 13f, forming internal insulation.

[0093] After the interior wall finishing material installation process and the insulation material installation process, the waterproofing process and exterior wall finishing material installation process shown in Figure 16 are carried out. In the waterproofing process, a breathable waterproof sheet 50 is installed on the first wood-frame wall panel 13d, the second wood-frame wall panel 13e, and the fourth wood-frame wall panel 13f. After the waterproofing process, the exterior wall finishing material installation process installs the exterior wall finishing material 51 on the first wood-frame wall panel 13d, the second wood-frame wall panel 13e, and the fourth wood-frame wall panel 13f. Siding material is used for the exterior wall finishing material 51.

[0094] In the waterproofing process, a breathable waterproof sheet 50 approximately the same size as the first wooden wall panel 13d (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) containing insulation material 46 in the first containment space 47 is attached to the outer end surface of the first wooden wall panel 13d, and a breathable waterproof sheet 50 approximately the same size as the first wooden wall panel 13d (head joint 26, upper frame 27, lower frame 28, first vertical frame A breathable waterproof sheet 50, approximately the same size as the second wooden wall panel 13e, is attached to the outer end surface of the second wooden wall panel 13f (29, second vertical frame 30, stud 31), and a breathable waterproof sheet 50, approximately the same size as the fourth wooden wall panel 13f, is attached to the outer end surface of the fourth wooden wall panel 13f (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31), which houses the insulation material 46 in the fourth storage space 57.

[0095] In the exterior wall finishing material installation process, the exterior wall finishing material 51 (siding material) is joined (fixed) to the outer end surface of the first wooden wall panel 13d (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) to which the breathable waterproof sheet 50 is attached, using screws (not shown). The exterior wall finishing material 51 (siding material) is joined (fixed) to the outer end faces of the second vertical frame 30 and studs 31 using screws (not shown), and the exterior wall finishing material 51 (siding material) is joined (fixed) to the outer end faces of the fourth wooden wall panel 13f (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, studs 31) to which the breathable waterproof sheet 50 is attached using screws (not shown). Upon completion of each process, the semi-finished wooden unit house 10B is completed. The wooden unit house 10B has a second opening space 58 located on the opposite side in the width direction of the fourth wooden wall panel 13f and having approximately the same area as the fourth wooden wall panel 13f.

[0096] The wooden unit house 10B is formed from wood-based ceiling plates 11b and wood-based floor plates 12b made from CLT, and wood-based first wall panels 13d, second wall panels 13e, and fourth wall panels 13f made from 2x4 lumber. This allows the forces of earthquakes and vibrations to be evenly distributed throughout the wooden unit house 10B without concentrating them at a single point, thereby preventing deformation, damage, and collapse of the wooden unit house 10B due to earthquakes and vibrations.

[0097] The wooden unit house 10B can create attractive ceilings and floors with appealing designs by utilizing wood-based ceiling plates 11b and wood-based floor plates 12b made from CLT, and can create attractive walls with appealing designs by utilizing wood-based first wall panels 13d, second wall panels 13e, and fourth wall panels 13f made from 2x4 lumber, thereby creating ceilings, walls, and floors that provide residents and visitors with the beauty, comfort, warmth, and tranquility that natural wood materials offer.

[0098] The wooden unit house 10B defines an internal living space 44 with a predetermined volume that is long in the front-to-back direction (or width direction), surrounded by a wooden ceiling plate 11b, a wooden floor plate 12b, and wooden first wall panels 13d, second wall panels 13e, and fourth wall panels 13f. Therefore, it is possible to create a living space 44 equipped with ceilings, walls, and floors that can provide the beauty, comfort, warmth, and tranquility that natural wood materials offer. The wooden unit house 10B makes extensive use of wood materials, which are sustainable and circular resources, thus effectively utilizing forest resources and contributing to the reduction of CO2 emissions, thereby reducing the environmental burden.

[0099] In the wooden unit house 10B, insulation material 46 (glass wool or cellulose fiber) is installed in the first storage space 47, second storage space 48, and fourth storage space 57 from the outside of the wooden first wall panel 13d, wooden second wall panel 13e, and wooden fourth wall panel 13f, forming internal insulation. Despite being internal insulation, the insulation material 46 is installed in the first storage space 47, second storage space 48, and fourth storage space 57 from the outside of the wooden first wall panel 13d, wooden second wall panel 13e, and wooden fourth wall panel 13f, so the wooden first wall panel The wiring cables, electrical appliances such as outlet boxes and outlet plates, plumbing equipment such as water supply and drainage pipes, and air conditioning equipment such as piping and ducts, all of which are located in the first, second, and fourth storage spaces 47, 48, and 57 of the Nell 13d, the second wood-based wall panel 13e, and the fourth wood-based wall panel 13f, do not get in the way when the insulation material is installed. The insulation material 46 can be smoothly installed in these spaces 47, 48, and 57, and a wooden unit house 10B with internal insulation created by the insulation material 46 can be quickly constructed without requiring much effort or time.

[0100] In the wooden unit house 10B, the ceiling and floor are formed by wood-based ceiling plates 11b and wood-based floor plates 12b made from CLT, and the walls are formed by wood-based first wall panels 13d, wood-based second wall panels 13e, and wood-based fourth wall panels 13f made using a standardized two-by-four construction method. By connecting the wood-based ceiling plates 11b, wood-based floor plates 12b, wood-based first wall panels 13d, wood-based second wall panels 13e, and wood-based fourth wall panels 13f according to a predetermined procedure, the wooden unit house 10B can be constructed easily and quickly by a contractor following the manual without the need for the superior skills of a skilled worker, and the wooden unit house 10B can be easily constructed with uniform quality and high strength.

[0101] Figure 17 is a perspective view of wooden unit house 10C as another example, and Figure 18 is a perspective view of wooden unit house 10C from the rear. Figure 19 is a front view of wooden unit house 10C from Figure 17, and Figure 20 is a rear view of wooden unit house 10C from Figure 17. In Figure 17, wooden unit house 10C is shown from the front. In Figures 17 and 18, the vertical direction is indicated by arrow X, the front-to-back direction by arrow Y, and the width direction by arrow Z. Note that the top and bottom views of wooden unit house 10C are the same as the top view of wooden unit house 10A shown in Figure 5 and the bottom view of wooden unit house 10A shown in Figure 6, so Figures 5 and 6 are used as a reference and the illustration of the top and bottom views of wooden unit house 10C is omitted.

[0102] The wooden unit house 10C is formed from a wood-based ceiling plate 11c of a predetermined area that unfolds horizontally, a wood-based floor plate 12c of a predetermined area that unfolds horizontally, and a wood-based wall panel 13 of a predetermined area that unfolds vertically. The wood-based ceiling plate 11c and the wood-based floor plate 12c are made from CLT (Cross Laminated Timber), similar to those of the wooden unit house 10A.

[0103] The wood-frame ceiling plate 11c of the wooden unit house 10C is formed into a roughly rectangular shape that is long in the front-to-back direction and has first and second end portions 14, 15 that extend in the width direction and third and fourth end portions 16, 17 that extend in the front-to-back direction. Alternatively, the wood-frame ceiling plate 11c may be formed into a roughly rectangular shape that is long in the width direction, in which case the wood-frame ceiling plate 11c has first and second end portions 14, 15 that extend in the front-to-back direction and third and fourth end portions 16, 17 that extend in the width direction. Multiple rafters 18 that extend in the width direction at equal intervals in the front-to-back direction are arranged on the upper surface of the wood-frame ceiling plate 11c, and roof sheathing plywood 19 is attached to the upper surface of these rafters 18. These rafters 18 and roof sheathing plywood 19 are fixed to the wood-frame ceiling plate 11c (CLT) with long screws (not shown). The top surface of the roof sheathing plywood 19 is coated with waterproofing 20 (film waterproofing (FRP waterproofing)).

Flooring 25 (sound-insulating wood flooring material with a special cushioning material to enhance sound insulation performance) is bonded to the upper surface of the wood-based floor plate 12c (CLT) with adhesive.

[0105] The wood-based wall panel 13 is formed from a first wood-based wall panel 13g with a predetermined area extending in the width direction (or front-to-back direction) and a second wood-based wall panel 13h with a predetermined area extending in the width direction (or front-to-back direction). The first wood-based wall panel 13g and the second wood-based wall panel 13h are made using the two-by-four construction method with two-by-four lumber, similar to the first wood-based wall panels 13a to the third wood-based wall panels 13c, and are formed into a roughly rectangular shape.

[0106] The first wooden wall panel 13g and the second wooden wall panel 13h are formed from a top joint 26 (square timber) and an upper frame 27 (square timber) extending in the front-to-back direction or width direction, a lower frame 28 (square timber) located below the upper frame 26 in the vertical direction and extending in the front-to-back direction or width direction, a first vertical frame 29 (square timber) located between the upper and lower frames 27 and 28 and extending in the vertical direction, a second vertical frame 30 (square timber) extending in the vertical direction from the first vertical frame 29, spaced apart in the front-to-back direction or width direction and facing each other, and a plurality of studs 31 (square timber) located between the first and second vertical frames 29 and 30, extending in the vertical direction and spaced apart in the front-to-back direction or width direction.

[0107] The head joints 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, and studs 31 are connected by standardized nails. The wood-based first wall panel 13g and second wall panel 13h are assembled from 2x4 lumber (head joints 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, and studs 31) to create a "framework" and form a highly rigid diaphragm.

[0108] The first wooden wall panel 13g has a first upper end portion 32 (head joint 26 and upper frame 27) extending in the width direction (or front-to-back direction), a first lower end portion 33 (lower frame 28) located below the first upper end portion 32 in the vertical direction and extending in the width direction (or front-to-back direction), a first side edge portion 34 (first vertical frame) extending in the vertical direction, and a second side edge portion 35 (second vertical frame) extending in the vertical direction, spaced apart from the first side edge portion 34 in the width direction (or front-to-back direction). Various shapes of window frames (sashes) and door frames can be made from the first wooden wall panel 13g.

After the interior wall finishing material installation process, the insulation material installation process installs the insulation material 46 onto the first wood-based wall panel 13g and the second wood-based wall panel 13h. Plasterboard with fire resistance and sound insulation properties is used for the interior wall finishing material 45. Glass wool or cellulose fiber is used for the insulation material 46.

[0117] In the interior wall finishing material installation process, the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end faces of the first wooden wall panel 13g (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown), and the interior wall finishing material 45 (plasterboard) is joined (fixed) to the inner end faces of the second wooden wall panel (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) using screws (not shown).

[0118] In the insulation material installation process, insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the first installation space 47 (installation space) of the first wooden wall panel 13g surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31, and insulation material 46 (glass wool or cellulose fiber) is installed (filled) in the second installation space 48 (installation space) of the second wooden wall panel 13h surrounded by the upper and lower frames 27, 28, the first and second vertical frames 29, 30, and their studs 31.

[0119] The insulation material 46 is installed in the first and second storage spaces 47 and 48 from the exterior side (outside of the wooden unit house 10C) of the first and second wooden wall panels 13g and 13h. In the first and second wooden wall panels 13g and 13h, the insulation material 46 is installed in the first and second storage spaces 47 and 48 from the exterior side of the panels 13g and 13h, forming internal insulation.

[0120] After the interior wall finishing material installation process and the insulation material installation process, the waterproofing process and exterior wall finishing material installation process shown in Figure 23 are carried out. In the waterproofing process, a breathable waterproof sheet 50 is installed on the first wood-based wall panel 13g and the second wood-based wall panel 13h. After the waterproofing process, the exterior wall finishing material 51 is installed on the first wood-based wall panel 13g and the second wood-based wall panel 13h in the exterior wall finishing material installation process. Siding material is used for the exterior wall finishing material 51.

[0121] In the waterproofing process, a breathable waterproof sheet 50, approximately the same size as the first wooden wall panel 13g, is attached to the outer end surface of the first wooden wall panel 13g (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31), which contains insulation material 46 in the first containment space 47. A breathable waterproof sheet 50, approximately the same size as the second wooden wall panel 13g, is attached to the outer end surface of the second wooden wall panel 13h (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31), which contains insulation material 46 in the second containment space 48.

[0122] In the exterior wall finishing material installation process, the exterior wall finishing material 51 (siding material) is joined (fixed) to the outer end surface of the first wooden wall panel 13g (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) to which the breathable waterproof sheet 50 is attached, using screws (not shown). The exterior wall finishing material 51 (siding material) is then joined (fixed) to the outer end surface of the second wooden wall panel 13h (head joint 26, upper frame 27, lower frame 28, first vertical frame 29, second vertical frame 30, stud 31) to which the breathable waterproof sheet 50 is attached, using screws (not shown). Upon completion of each process, the semi-finished wooden unit house 10C is completed. The wooden unit house 10C has a first opening space 52 of a predetermined area located between the first side edge 34 of the first wooden wall panel 13g and the first side edge 38 of the second wooden wall panel 13h, and a second opening space 58 of a predetermined area located between the second side edge 35 of the first wooden wall panel 13g and the second side edge 39 of the second wooden wall panel 13h, and spaced apart from the first opening space 52 in the width direction.

[0123] The wooden unit house 10C is formed from wood-based ceiling plates 11c and wood-based floor plates 12c made from CLT, and wood-based first wall panels 13g and wood-based second wall panels 13h made from 2x4 lumber. This allows for even distribution of seismic and vibrational forces throughout the wooden unit house 10C without concentrating them at a single point, thus preventing deformation, damage, and collapse of the wooden unit house 10C due to earthquakes and vibrations.

[0124] The wooden unit house 10C utilizes wood-based ceiling plates 11c and wood-based floor plates 12c made from CLT to create aesthetically pleasing ceilings and floors with the attractive design (aesthetics) inherent in wood-based materials. It also utilizes wood-based first wall panels 13g and wood-based second wall panels 13h made from 2x4 lumber to create aesthetically pleasing walls with the attractive design (aesthetics) inherent in wood-based materials. This allows for the creation of ceilings, walls, and floors that provide residents and visitors with the beauty, comfort, warmth, and tranquility inherent in natural wood-based materials.

[0125] The wooden unit house 10C defines an internal living space 44 with a predetermined volume that is long in the front-to-back direction (or width direction), surrounded by a wooden ceiling plate 11c, a wooden floor plate 12c, a wooden first wall panel 13g, and a wooden second wall panel 13h. Therefore, it is possible to create a living space 44 equipped with a ceiling, walls, and floor that can provide the beauty, comfort, warmth, and tranquility that natural wood materials offer. The wooden unit house 10C makes extensive use of wood materials, which are sustainable and circular resources, thus making effective use of forest resources and reducing CO2 emissions. 2 By contributing to the reduction of [unspecified factor], the environmental burden can be reduced.

[0126] In the wooden unit house 10C, insulation material 46 (glass wool or cellulose fiber) is installed in the first and second storage spaces 47 and 48 from the outside of the first and second wooden wall panels 13g and 13h to form internal insulation. Despite being internal insulation, since the insulation material 46 is installed in the first and second storage spaces 47 and 48 from the outside of the first and second wooden wall panels 13g and 13h, electrical appliances such as wiring cables, outlet boxes, and outlet plates, plumbing equipment such as water supply and drainage pipes, and air conditioning equipment such as piping and ducts located in the first storage space 47 of the first wooden wall panel 13g and the second storage space 48 of the second wooden wall panel 13h do not get in the way when installing the insulation material. This allows the insulation material 46 to be installed smoothly in the first and second storage spaces 47 and 48, and the wooden unit house 10C with internal insulation created by the insulation material 46 can be quickly constructed without requiring much effort or time.

[0127] In the wooden unit house 10C, the ceiling and floor are formed by wood-based ceiling plates 11c and wood-based floor plates 12c made from CLT, and the walls are formed by wood-based first wall panels 13g and wood-based second wall panels 13h made using a standardized two-by-four construction method. By connecting the wood-based ceiling plates 11c, wood-based floor plates 12c, wood-based first wall panels 13g, and wood-based second wall panels 13h according to a predetermined procedure, the wooden unit house 10C can be constructed easily and quickly by a contractor following the manual without the need for the superior skills of a skilled worker, and the wooden unit house 10C can be easily constructed with uniform quality and high strength.

[0128] Figure 24 is a front view of the wooden unit house 10A of Figure 1 with the foundation 60 installed, and Figure 25 is a front view of the wooden unit house 10B of Figure 11 with the foundation 60 installed. Figure 26 is a front view of the wooden unit house 10C of Figure 18 with the foundation 60 installed, and Figure 27 is a diagram showing an example of a connecting means for connecting the wooden floor plates 12a to 12c and the foundation 60.

[0129] After the semi-finished wooden unit houses 10A, 10B, and 10C are assembled at the assembly plant, these wooden unit houses 10A to 10C are transported to the designated installation site by designated means of transport (transport vehicles, rail, or ship). At the installation site, foundation work is carried out on the foundation 59 for installing and fixing the wooden unit houses 10A to 10C. In the foundation work, the horizontal position of the planned building and the height of the foundation 59 are marked at the installation site, then water piles are installed, water crossbars are placed and string lines are stretched (layout). Next, the ground is excavated with heavy machinery to create the foundation 59, and the excavation depth is checked and adjusted (excavation).

[0130] Crushed stone is brought in and laid at the bottom of the excavation and the base slab. The crushed stone is then compacted and compacted with a rammer. The surface is leveled and finished with a plate converter (groundwork). A moisture-proof film is laid over the entire base slab, ensuring that there are no wrinkles, to prevent moisture from the ground from entering the interior of the wooden unit house 10A. The reinforcement bars that will serve as guides are inserted into the crushed stone, which is level with the top of the lean concrete. Ready-mix concrete is poured up to the top of the guides, and the surface is leveled. After the lean concrete has hardened, markings are made. In case the foundation 59 is to be offset from the center line, markings are made not only for the center line but also for the formwork (lean concrete).

[0131] Considering work efficiency, the reinforcing bars are spaced apart and the outer perimeter is temporarily assembled. Once a certain amount of assembly is complete, reinforcing bars are placed to form lap splices according to the diameter of the reinforcing bars and tied together. Next, the reinforcing bars of the rising section and the base section are tied together. Once the outer perimeter and base section are all assembled, the reinforcing bars of the inner rising section are laid. The reinforcing bars are spaced apart starting from the back of the building. Once a certain amount of spacing is complete, spacers (cubes) are placed. The end hooks of the main reinforcing bars of the base section are tied with wire to the stirrups of the rising section on the shorter side. The main reinforcing bars of the base section are tied to the distribution reinforcing bars and fixed in place. The distribution reinforcing bars are tied to the stirrups of the rising section on the longer side (reinforcing bar placement).

[0132] Sleeves are installed on the stirrups of the rising sections, and pipes such as drainage pipes and water supply pipes are installed that rise from below GL through the base slab (around the piping). Next, in order to fix the formwork on the outside of the outer perimeter, width-retaining separators are fixed in line with the markings made on the lean concrete before assembling the formwork. Formwork is assembled only on the outside of the outer perimeter. Single pipes are attached to the outside of the formwork to prevent it from collapsing when the ready-mix concrete is poured. Once the pouring of the base slab is complete, the formwork for the inside of the outer perimeter and the rising sections inside the foundation are placed on the width-retaining separators installed on the base slab and assembled. Anchor bolts whose lower ends will be below the top of the poured base slab are installed before pouring. Ready-mix concrete is pumped in using a concrete pump truck and poured into the foundation 59. A vibrator is used to compact the ready-mix concrete. Before the ready-mix concrete hardens, the areas that have been poured are leveled sequentially with a finishing rake to make the surface smooth. Anchor bolts are installed, formwork for the rising sections is assembled, ready-mix concrete is pumped in using a concrete pump truck, poured into the formwork, and compacted with a vibrator. Leveling compound is poured over the top of the foundation to prevent any level differences as it will come into contact with the main structure (sill plate). Once all work is complete, a sheet is placed over the top to allow it to cure (concrete pouring).

[0133] Mark the placement of the base 60 on the top of the foundation. Line up the base 60 according to the numbering and the fixing positions of the foundation 59. Mark the positions of the anchor bolts on the base 60 and drill holes in the base according to the markings. Lay the foundation packing on top of the foundation 59, lay the base 60 according to the drawing, and fix the anchor bolts while checking the position of the anchor bolts and whether there is any interference with the mortise holes. Screw the shortened steel posts to the main beams, overlap the joints of the base and main beams, and tap the main beams with a mallet to fit them into the base 60s. Adjust the height of the steel posts to make the main beams level (base laying).

[0134] The wooden unit houses 10A to 10C are lifted by a crane, and the wood-based floor plates 12a to 12c made from CLT of the wooden unit houses 10A to 10C are placed on the base 60 laid on the foundation wall. The wood-based floor plates 12a to 12c are then connected (fixed) to the base 60 using vertical screws 61 and angled screws 62. By using vertical screws 61 and angled screws 62 to connect the wood-based floor plates 12a to 12c to the base 60 laid on the foundation wall, the wooden unit houses 10A to 10C can be securely and firmly connected to the wood-based floor plates 12a to 12c made from CLT to the base 60 laid on the foundation wall, making it possible to create a sturdy wooden unit house 63.

[0135] Furthermore, after connecting (fixing) the wooden floor plates 12a to 12c to the base 60, sliding windows 64, casement windows 64, ground-level windows 64, etc. are installed in the window frames, and the entrance door 66 (swing door) is installed in the door frame. In addition, a washbasin (sanitary equipment), flush toilet (sanitary equipment), sink (plumbing equipment), gas stove (gas equipment), induction cooktop, range hood (air conditioning equipment), system kitchen, unit bath, air conditioner (air conditioning equipment), etc. are installed. Furthermore, electrical equipment such as distribution boards, low-voltage boards, outlets, and various switches are installed, and a gas water heater is installed.

In the wooden unit house 63, four wooden unit houses 10C1 to 10C4 are positioned between one wooden unit house 10A1 and one wooden unit house 10B1, and by connecting these unit houses 10A1, 10B1, 10C1 to 10C4, a toilet, washroom, bathroom, entrance hall, kitchen, and living room are created, as shown in Figure 31.

[0138] With one wooden unit house 10C5 positioned between two wooden unit houses 10A2 and 10B2, connecting these unit houses 10A2, 10B2, and 10C5 creates two Western-style rooms (bedrooms), as shown in Figure 31. Hold-down hardware 65 (tension hardware) (predetermined connecting means) (see Figure 27), vertical screws 61 (vertical screws), and diagonal screws 62 (diagonal screws) (predetermined connecting means) are used to connect these wooden unit houses 10A1, 10A2, 10B1, 10B2, 10C1 to 10C4 to each other.

[0139] A flush toilet (sanitary equipment), a washbasin (sanitary equipment), and a unit bath are installed in wooden unit house 10A1, and the toilet, washroom, and bathroom are built into wooden unit house 10A1. Partition walls are installed between wooden unit house 10A1 and wooden unit house 10C1, and doors are installed in the partition walls. A front door is installed in wooden unit house 10C1, and wooden unit house 10C1 forms the entrance hall.
