Summary of the Invention

Problems to be Solved by the Invention

[0004] The wiring fixing method disclosed in Patent Document 1 requires that ducts, pipes, air conditioning and ventilation equipment, and other equipment installed in the ceiling space be arranged in order from the top down. Therefore, electrical wiring cannot be installed until the ducts, pipes, air conditioning and ventilation equipment have been placed.

Another object of the present invention is to provide a wiring method that allows indoor electrical wiring replacement and repair work to be performed quickly and efficiently. [Means for solving the problem]

[0006] The premise of the present invention for solving the aforementioned problems is a method for wiring indoor electrical wiring in a wooden house made by connecting at least two or more wooden units.

[0007] The features of the present invention under the above premise are that the wooden unit is formed from a substantially flat wooden ceiling plate of a predetermined area which is formed into a rectangle that is long in the front-to-back direction or in the width direction and extends horizontally, a substantially flat wooden floor plate of a predetermined area which is formed into a rectangle that is long in the front-to-back direction or in the width direction and extends horizontally, and a wooden wall panel of a predetermined area which is positioned between the wooden ceiling plate and the wooden floor plate and is formed into a rectangle and extends vertically, and the wiring method is a connection position wiring step which involves wiring each indoor electrical wiring connected to each lighting fixture, each outlet or each switch installed in each wooden unit to the wooden ceiling plate of each wooden unit to create a connection position wiring path, and the indoor electrical wiring connected to the connection position wiring path to each wooden The system comprises a ceiling wiring process, which involves wiring on the wooden ceiling plate of the manufactured unit to create a ceiling wiring route; a ceiling penetration wiring process, which involves passing the indoor electrical wiring connected to the ceiling wiring route through wiring penetration holes that penetrate the wooden ceiling plate to create a ceiling penetration wiring route; a beam type wiring process, which involves wiring the indoor electrical wiring from the ceiling penetration wiring route into the beam type of the wooden unit to create a beam type wiring route; and a first distribution board connection process, which involves connecting the indoor electrical wiring from the beam type wiring route to a distribution board installed in the wooden house to create a first distribution board connection route. The length of the indoor electrical wiring from the connection position wiring route in the wooden unit to the first distribution board connection route is adjusted to be a length that can be connected to the distribution board but does not exceed the length of the distribution board.

[0008] In one example of the present invention, the connection position wiring process, the ceiling wiring process, and the ceiling penetration wiring process are carried out in an assembly plant where wooden units are assembled, and the connection position wiring routes, ceiling wiring routes, and ceiling penetration wiring routes are created in each wooden unit at the assembly plant, and the beam-type wiring process and the first power distribution panel connection process are carried out at the construction site of the wooden house, and the beam-type wiring routes and the first power distribution panel connection route are created at the construction site.

[0009] Another example of the present invention is a wooden unit having first and second wood-based wall panels that face each other and extend in one direction, and third and fourth wood-based wall panels that face each other and extend in intersecting directions that intersect with the one direction, and in a wooden house, a plurality of wooden units are arranged in one direction with the first wood-based wall panel of one wooden unit and the second wood-based wall panel of the other wooden unit facing each other, and a beam-type wiring process is performed at the construction site by arranging indoor electrical wiring inside a beam-type that is made on the upper part of the first wood-based wall panel of one wooden unit and / or the second wood-based wall panel of the other wooden unit and extends in one direction, thereby creating a beam-type wiring route.

[0010] Another example of the present invention is a ceiling wiring process in which indoor electrical wiring is routed between joists installed on the upper surface of the wooden ceiling plate of the wooden unit in the assembly plant to create a ceiling wiring route, and in wooden buildings, waterproofing work is performed on top of the indoor electrical wiring routed between the joists.

[0011] Another example of the present invention is a connection position wiring process in which indoor electrical wiring is passed through equipment connection through-holes that penetrate the wooden ceiling plate of a wooden unit and connected to lighting fixtures installed on the wooden ceiling plate, or indoor electrical wiring is passed through the wooden wall panel of a wooden unit and connected to outlets or switches installed on the wooden wall panel.

[0012] Another example of the present invention is a ceiling penetration wiring process in which, after inserting indoor electrical wiring through a wiring penetration hole, wiring putty or caulking material is filled into the wiring penetration hole to airtightly seal the ceiling penetration wiring route.

[0013] Another example of the present invention is a wooden house of two stories or more, in which wooden units are connected vertically, and the wiring method includes an EPS wiring step of creating an EPS wiring path that runs indoor electrical wiring wired to the beams of the upper floor wooden unit to an electrical conduit compartment (EPS) installed adjacent to the beams, and down to the lower floor wooden house through the electrical conduit compartment (EPS) and the indoor electrical wiring of the upper floor wooden house, and a second distribution board connection step of connecting the indoor electrical wiring from the EPS wiring path to a distribution board to create a second distribution board connection path, wherein the length of the indoor electrical wiring from the connection position wiring path in the upper floor wooden unit to the second distribution board connection path is adjusted to a length that can be connected to a distribution board but does not exceed the length of the distribution board.

[0014] Another example of the present invention is that the connection position wiring process, ceiling wiring process, and ceiling penetration wiring process for the upper floor wooden units are carried out in the assembly plant where the upper floor wooden units are assembled, and the connection position wiring routes, ceiling wiring routes, and ceiling penetration wiring routes are created in each upper floor wooden unit at the assembly plant, and the beam type wiring process and the second distribution panel connection process are carried out at the construction site of the upper floor wooden house, and the beam type wiring routes and the second distribution panel connection routes are created in the upper floor wooden house at the construction site.

[0015] Another example of the present invention is a wood-based floor plate made from cross-laminated timber (CLT), a wood-based ceiling plate made from cross-laminated ceiling board (CLT), and a wood-based wall panel made from two-by-four lumber, with wiring penetration holes and equipment connection penetration holes drilled in the cross-laminated ceiling board (CLT). [Effects of the Invention]

[0016] According to the wiring method of the present invention, each indoor electrical wiring connected to each lighting fixture, outlet, or switch installed in each wooden unit is wired to the wooden ceiling plate of each wooden unit to create a connection position wiring path, these indoor electrical wirings are wired on top of the wooden ceiling plate of each wooden unit to create a ceiling wiring path, these indoor electrical wirings are passed through wiring holes that penetrate the wooden ceiling plate to create a ceiling penetration wiring path, these indoor electrical wirings connected to the ceiling penetration wiring path are wired inside the beam-shaped part of the wooden unit to create a beam-shaped wiring path, these indoor electrical wirings connected to the beam-shaped wiring path are connected to a distribution board installed in the wooden house to create a first distribution board connection path, and the length of these indoor electrical wirings from the connection position wiring path in each wooden unit to the first distribution board connection path is adjusted to a length that can be connected to the distribution board but does not exceed the length of the distribution board, so that the indoor electrical wiring wired to the beam-shaped part of the wooden unit can be connected to the distribution board via the first distribution board connection path, and the indoor electrical wirings of each wooden unit can be connected to the distribution board together. The wiring method involves connecting the indoor electrical wiring of the wooden units to the distribution board through the beams of the wooden units, thus completing the wiring work quickly and efficiently without requiring much time or effort. This allows the electrical wiring work in a wooden house formed from each wooden unit to be completed within the scheduled construction period. The wiring method clearly defines the connection points, wiring routes, ceiling wiring routes, ceiling penetration wiring routes, beam wiring routes, and the first connection route to the distribution board. This makes it easy to replace or repair the indoor electrical wiring in a wooden house formed from each wooden unit, allowing the replacement or repair work to be completed quickly and efficiently. The wiring method ensures that the length of the indoor electrical wiring does not exceed the length of the distribution board, thus eliminating wasted indoor electrical wiring that would otherwise be required.

[0017] In this wiring method, the connection point wiring process, ceiling wiring process, and ceiling penetration wiring process are carried out at the assembly plant where the wooden units are assembled. At the assembly plant, the connection point wiring routes, ceiling wiring routes, and ceiling penetration wiring routes are created for each wooden unit. The beam-type wiring process and the first distribution panel connection process are carried out at the construction site of the wooden house. At the construction site, the beam-type wiring routes and the first distribution panel connection route are created. As a result, the connection point wiring routes, ceiling wiring routes, and ceiling penetration wiring routes are created in advance for the wooden units at the assembly plant. This eliminates the need for wiring work for these routes at the construction site of the wooden house. Furthermore, by creating the beam-type wiring routes and the first distribution panel connection route at the construction site of the wooden house, the indoor electrical wiring work can be completed. This wiring method simplifies the wiring work at the construction site, saving time and effort. It allows for efficient and quick indoor electrical wiring work in wooden houses formed from each wooden unit, and enables the electrical wiring work to be completed within the scheduled construction period.

[0018] The wiring method involves arranging indoor electrical wiring within a beam-shaped structure extending in one direction, created on the upper part of the first wooden wall panel of one unit and / or the second wooden wall panel of the other unit at the construction site of a wooden house, where multiple wooden units are lined up in one direction with the first wooden wall panel of one wooden unit facing the second wooden wall panel of the other wooden unit. This creates a beam-shaped wiring route, and the indoor electrical wiring is connected to the distribution board through the beam-shaped structure of the wooden unit at the construction site, thus simplifying the wiring work at the construction site. This method requires less time and effort, allows for efficient and quick wiring of indoor electrical wiring in a wooden house formed from each wooden unit, and enables the electrical wiring work to be completed within the scheduled construction period.

[0019] The wiring method involves creating a ceiling wiring route by running indoor electrical wiring between joists installed on the upper surface of the wooden ceiling plates of the wooden units at the assembly plant, and then performing waterproofing work on top of the indoor electrical wiring run between the joists. This eliminates the need for wiring the ceiling wiring route and waterproofing work on the wooden ceiling plates at the construction site of the wooden house, saving time and effort. It allows for efficient and quick wiring of indoor electrical wiring in wooden houses formed from each wooden unit, and enables the electrical wiring work to be completed within the scheduled construction period.

[0020] The wiring method involves connecting indoor electrical wiring to lighting fixtures installed on wooden ceiling plates through equipment connection through-holes that penetrate the wooden ceiling plates of the wooden unit, or connecting indoor electrical wiring to outlets installed on wooden wall panels of the wooden unit. This allows indoor electrical wiring to be easily connected to lighting fixtures and also to outlets or switches, enabling quick and efficient connection of indoor electrical wiring to various electrical devices in the assembly plant.

[0021] The wiring method involves inserting the indoor electrical wiring through the wiring penetration hole, and then filling the hole with wiring putty or sealant to airtightly seal the ceiling penetration wiring route. This prevents water leakage from the wiring penetration hole, short circuits in the indoor electrical wiring, and deterioration of the indoor electrical wiring, thus ensuring the safety of electrical equipment in wooden houses.

[0022] The wiring method involves routing indoor electrical wiring from the beam-type wooden units on the upper floor to the electrical conduit compartment (EPS) installed adjacent to the beam-type, creating an EPS wiring path that runs these indoor electrical wirings from the upper floor wooden houses down to the lower floor wooden houses through the electrical conduit compartment (EPS), connecting these indoor electrical wirings connected to the EPS wiring path to the distribution board to create a second distribution board connection path, and adjusting the length of these indoor electrical wirings from the connection point wiring path in the upper floor wooden units to the second distribution board connection path so that they are long enough to be connected to the distribution board but do not exceed the length of the distribution board. Therefore, the indoor electrical wiring of each upper floor wooden unit can be connected to the distribution board via the beam-type and electrical conduit compartment (EPS), and the indoor electrical wiring of each upper floor wooden unit can be connected to the distribution board together. The wiring method involves connecting the indoor electrical wiring of the upper floor wooden units to the distribution board through the beams and electrical conduit compartments (EPS) of the upper floor wooden units, thus saving time and effort. This allows for quick and efficient wiring of the indoor electrical wiring in the wooden house formed from the upper floor wooden units, enabling completion within the planned construction period. The wiring method clearly defines the connection points, wiring routes, ceiling wiring routes, ceiling penetration wiring routes, beam wiring routes, EPS wiring routes, and the second connection route to the distribution board in the upper floor wooden house. This makes it easy to replace or repair the indoor electrical wiring in the wooden house formed from the upper floor wooden units, allowing for quick and efficient replacement or repair work. The wiring method ensures that the length of the indoor electrical wiring does not exceed the length of the distribution board, eliminating wasted indoor electrical wiring caused by wiring exceeding the length of the distribution board.

[0023] The wiring method involves the connection position wiring process, ceiling wiring process, and ceiling through-wiring process of the upper-floor wooden units being carried out in an assembly factory where the upper-floor wooden units are assembled. In the assembly factory, the connection position wiring path, ceiling wiring path, and ceiling through-wiring path are created for each upper-floor wooden unit. The beam-type wiring process and the distribution board second connection process are carried out at the facility site of the upper-floor wooden house. At the facility site, the beam-type wiring path and the distribution board second connection path are created for the upper-floor wooden house. Therefore, in the assembly factory, the connection position wiring path, ceiling wiring path, and ceiling through-wiring path are created in advance for the upper-floor wooden units, and the wiring work for these wiring paths can be omitted at the facility site of the wooden house. Furthermore, by creating the beam-type wiring path and the distribution board second connection path at the facility site of the wooden house, the wiring work for the indoor electrical wiring can be completed. The wiring method can simplify the wiring work at the facility site, without requiring time and effort, and can efficiently carry out the wiring work for the indoor electrical wiring in a wooden house with two or more floors formed from each wooden unit in a short time, and can complete the electrical wiring work within the scheduled construction period.

[0024] The wiring method is such that the wooden floor plate is made from a cross-laminated timber (CLT), the wooden ceiling plate is made from a cross-laminated ceiling board (CLT), the wooden wall panel is made from a two-by-four material, the wiring through-holes and equipment connection through-holes are drilled in the cross-laminated ceiling board (CLT). The indoor electrical wiring is passed from the ceiling wiring path through the wiring through-holes of the cross-laminated ceiling board (CLT) to create the ceiling through-wiring path. The indoor electrical wiring is wired from the ceiling through-wiring path into the interior of the beam type to create the beam-type wiring path. The indoor electrical wiring wired inside the beam type is connected to the distribution board via the distribution board first connection path or the distribution board second connection path from the beam-type wiring path. Therefore, the indoor electrical wiring wired to the beam type of the wooden unit can be connected to the distribution board via the distribution board first connection path or the distribution board second connection path, without requiring time and effort, and the wiring work for the indoor electrical wiring in the wooden house formed from each wooden unit can be efficiently carried out in a short time.

[0026] Referring to the accompanying drawings, the details of the wiring method of the indoor electrical wiring according to the present invention will be described as follows. Note that FIG. 1 is a perspective view of a wooden unit 10A shown as an example, seen from the front side, and FIG. 2 is a perspective view of the wooden unit 10A of FIG. 1 seen from the back side.

The ceiling wiring diagram 7 is a front view of the wooden unit 10B in Figure 4, and Figure 8 is a top view of the wood-based ceiling plate 11b that forms the wooden unit 10B. Figures 4 and 8 show the unit with the roof plywood 20 removed. In Figures 1 and 5, the vertical direction is indicated by arrow X, the front-to-back direction by arrow Y, and the width direction by arrow Z.

[0027] The wiring method involves wiring indoor electrical wiring 33 to a wooden house 10 (wooden unit house) made by connecting at least two or more wooden units 10A and 10B. The wiring method includes connection position wiring, ceiling wiring, ceiling penetration wiring, beam type wiring, and distribution board first connection. The wooden units 10A in Figure 1 and 10B in Figure 5, on which the wiring method is implemented, are assembled at an assembly plant, then transported to a designated facility site (installation location) by a designated means of transport, and installed (built up) at the facility site.

[0028] By combining two or more wooden units 10A and 10B and installing them at the construction site, wooden houses 10 (wooden unit houses) with various floor plans are constructed. Transport vehicles, railways, and ships are used as means of transportation. In terms of wiring methods, the connection position wiring process, ceiling wiring process, and ceiling penetration wiring process are carried out at the assembly plant (manufacturing plant) where the wooden units 10A and 10B are assembled (manufactured), while the beam type wiring process and the first distribution board connection process are carried out at the construction site of the wooden house 10.

[0029] The wooden unit 10A shown in Figure 1 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 cross-laminated timber (CLT) which is formed by arranging sawn timbers (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.

[0030] Cross-laminated timber (CLT) ceiling panels can be made in any of the following configurations: 3-ply, 3-layer, 4-ply, 5-ply, 5-ply, 7-ply, 7-ply, or 9-ply. Cross-laminated timber (CLT) panels can be made from cedar (Cryptomeria japonica), cypress (Cypress) (Cypress CLT panels), larch (Larch) (Larch CLT panels), or fir (Abies sachalinensis) (Abies sachalinensis). Cross-laminated timber (CLT) ceiling panels offer excellent thermal insulation and energy-saving benefits, superior seismic resistance, and are lighter than reinforced concrete structures. Furthermore, any type of cross-laminated timber (CLT) developed in the future can be used.

[0031] The wooden ceiling plate 11a of the wooden unit house 10a in Figure 1 is formed into a roughly rectangular shape that is long in the front-to-back direction, and has a first end edge 14 (front end edge) and a second end edge 15 (rear end edge) that extend in the front-to-back direction, and a first side edge 16 and a second side edge 17 that extend in the width direction. Multiple furring strips 19 that extend at predetermined intervals in the front-to-back direction are attached to the upper surface 18 of the wooden ceiling plate 11a. Roof plywood 20 is attached to these furring strips 19. These furring strips 19 and roof plywood 20 are fixed to the wooden ceiling plate 11a (orthogonal laminated ceiling board) with long screws (not shown).

[0032] The wooden floor plate 12a of the wooden unit house 10A in Figure 1 is made from cross-laminated timber (CLT), similar to the wooden ceiling plate 11a. The wooden floor plate 12a is formed into a roughly rectangular shape that is long in the front-to-back direction and has a first edge portion 21 (front edge portion) and a second edge portion 22 (rear edge portion) that extend in the front-to-back direction, and a first side edge portion 23 and a second side edge portion 24 that extend in the width direction. Flooring is applied to the upper surface of the wooden floor plate 12a (cross-laminated timber). The flooring (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 12a (cross-laminated timber) with adhesive.

[0033] The wooden wall panels 13 of the wooden unit house 10A in Figure 1 are formed from a first wooden wall panel 13a with a predetermined area extending in the width direction, a second wooden wall panel 13b with a predetermined area extending in the width direction, and a third wooden wall panel 13c with a predetermined area extending in the front-to-back direction. The first to third wooden wall panels 13a to 13c are made using the two-by-four construction method with two-by-four lumber and are formed into a roughly rectangular shape.

[0034] The wooden first to third wall panels 13a to 13c, although not shown in the diagram, are formed from a top joint (square timber) and top frame (square timber) extending in the front-to-back or width direction, a bottom frame (square timber) located below the top frame and extending in the front-to-back or width direction, a first vertical frame (square timber) located between the top and bottom frames and extending in the vertical direction, a second vertical frame (square timber) extending in the vertical direction, spaced apart from the first vertical frame in the front-to-back or width direction, and a plurality of studs (square timber) located between the first and second vertical frames, extending in the vertical direction and spaced apart in the front-to-back or width direction.

[0035] The top ties, top frame, bottom frame, first vertical frame, second vertical frame, and studs are connected by standardized nails. The first to third wood-based wall panels are constructed by assembling 2x4 lumber (top ties, top frame, bottom frame, first vertical frame, second vertical frame, and studs) to form a "framework" that creates a highly rigid diaphragm.

[0036] The first wooden wall panel 13a has an upper end portion 25 (head joint and upper frame) extending in the width direction, a lower end portion 26 (lower frame) located vertically below the upper end portion 25 and extending in the width direction, and side edge portions 27, 28 (first vertical frame and second vertical frame) extending vertically from the upper end portion 25 toward the lower end portion 26. Various shapes of window frames (sashes), door frames, spaces, etc. are made in the first wooden wall panel 13a.

[0037] The second wooden wall panel 13b is positioned opposite the first wooden wall panel 13a, spaced apart in the front-to-back direction. The second wooden wall panel 13b has an upper end portion 25 (head joint and upper frame) extending in the width direction, a lower end portion 26 (lower frame) located below the upper end portion 25 in the vertical direction and extending in the width direction, and side edge portions 27, 28 (first vertical frame and second vertical frame) extending vertically from the upper end portion 25 toward the lower end portion 26. Various shapes of window frames (sashes), door frames, spaces, etc. are made in the second wooden panel 13b.

[0038] The third wooden wall panel 13c is located between the side edge 27 of the first wooden wall panel 13a and the side edge 27 of the second wooden wall panel 13b. The third wooden wall panel 13c has an upper end portion 25 (head joint and upper frame) extending in the front-to-back direction, a lower end portion 26 (lower frame) located below the upper end portion 25 in the vertical direction and extending in the front-to-back direction, and side edge portions 27, 28 (first vertical frame, second vertical frame) extending vertically from the upper end portion 25 toward the lower end portion 26. Window frames (sashes) of various shapes are made on the third wooden panel 13c. Although not shown in the illustration, 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, refrigerant pipes and drain hoses for air conditioners, and outlets and switches are drilled.

[0039] In the wooden unit 10A shown in Figure 1, an angle member made of wood is attached to the corner where the wooden ceiling plate 11a and the wooden first wall panel 13a intersect, creating a beam-like structure 29 extending in one direction from the wooden ceiling plate 11a, the wooden first wall panel 13a, and the angle member. The beam-like structure 29 forms an indoor electrical wiring insertion space 30 with a predetermined volume and a rectangular cross-section, extending in one direction.

[0040] In the wooden unit 10A shown in Figure 1, the first to third wooden wall panels 13a to 13c are connected to the wooden ceiling plate 11a and the wooden floor plate 12a, with the first wooden wall panel 13a and the third wooden wall panel 13c being connected, and the second wooden wall panel 13b and the third wooden wall panel 13c being connected. By connecting the first to third wooden wall panels 13a to 13c to the wooden ceiling plate 11a and the wooden floor plate 12a, and by connecting the first to third wooden wall panels 13a to 13c, an internal living space with a predetermined volume that is long in the front-to-back direction (or width direction) is defined, surrounded by the wooden ceiling plate 11a, the wooden floor plate 11b, and the first to third wooden wall panels 13a to 13c.

[0041] The wooden ceiling plate 11a and the wooden first to third wall panels 13a to 13c are connected by hold-down hardware (tension hardware) and by at least diagonal screws (angled screws) among vertical screws (vertical screws). The wooden floor plate 12a and the wooden first to third wall panels 13a to 13c are connected by hold-down hardware (tension hardware) and by at least diagonal screws (angled screws) among vertical screws (vertical screws). The wooden first to third wall panels 13a to 13c are connected by long screws.

[0042] As shown in Figure 4, a wiring through-hole 31 is formed (drilled) on the first side edge 16 of the wooden ceiling plate 11a (on the side of the first wooden panel 13a), penetrating the wooden ceiling plate 11a vertically. A lighting equipment connection through-hole 32 is formed (drilled) approximately in the center of the wooden ceiling plate 11a, penetrating the wooden ceiling plate 11a vertically. The wiring through-hole 31 and the lighting equipment connection through-hole 32 are manufactured at the assembly plant for the wooden unit 10A.

[0043] The wiring method involves connecting indoor electrical wiring 33 to indoor lighting fixtures 40 (lighting fixtures) installed on the wooden ceiling plate 11a of the wooden unit house 10A, inserting the indoor electrical wiring 33 through the lighting fixture connection through-hole 32, extending the indoor electrical wiring 33 from the lower surface to the upper surface 18 of the wooden ceiling plate 11a, and wiring the indoor electrical wiring 33 up to the upper surface 18 of the wooden ceiling plate 11a to create a connection position wiring path 34 using the indoor electrical wiring 33 (connection position wiring process).

[0044] Alternatively, the indoor electrical wiring 33 is inserted through the lighting fixture connection through-hole 32, the indoor electrical wiring 33 is extended from the upper surface 18 to the lower surface of the wooden ceiling plate 11a of the wooden unit house 10A, and the indoor electrical wiring 33 is connected to the indoor lighting fixture 40 (lighting fixture) to create a connection position wiring path 34 using the indoor electrical wiring 33 (connection position wiring process). In the connection position wiring process, after inserting (wiring) the indoor electrical wiring 33 through the lighting fixture connection through-hole 32, waterproofing work is performed to airtightly seal the connection position wiring path 36 (indoor electrical wiring 33) by filling the lighting fixture connection through-hole 32 with wiring putty or caulking material.

[0045] The wiring method involves connecting the indoor electrical wiring 33 to the outdoor lighting fixture 40 (lighting fixture) installed on top of the second wooden wall panel 13b of the wooden unit house 10A, extending the indoor electrical wiring 33 to the upper frame of the two-by-four lumber forming the second wooden wall panel 13b, and then wiring the indoor electrical wiring 33 to the upper surface 18 of the wooden ceiling plate 11a to create a connection point wiring path 34 (connection point wiring process). Alternatively, the indoor electrical wiring 33 is extended from the upper surface 18 of the wooden ceiling plate 11a of the wooden unit house 10A to the upper frame of the two-by-four lumber forming the second wooden wall panel 13b, and then connecting the indoor electrical wiring 33 to the outdoor lighting fixture 40 to create a connection point wiring path 34 (connection point wiring process).

The ends of the indoor electrical wiring 33 that form the ceiling penetration wiring route 36 hang down from the lower surface of the wooden ceiling plate 11b of the wooden unit house 10B.

[0073] After the connection point wiring process, ceiling wiring process, and ceiling penetration wiring process are completed, waterproofing work is performed on top of the plywood sheathing 20 of the wood-based ceiling plate 11b (on top of the indoor electrical wiring 33 wired between the joists 19). The waterproofing work can be done using one of the following methods: FRP waterproofing, urethane waterproofing, sheet waterproofing, or asphalt waterproofing. In addition, waterproofing work on the wood-based ceiling plate 11b of the wooden unit 10B can also be performed at the facility site.

[0074] The indoor electrical wiring 33 of the connection point wiring route 34, the indoor electrical wiring 33 of the ceiling penetration wiring route 36, and the indoor electrical wiring 33 of the ceiling wiring route 35 are wired at the assembly plant where the wooden unit 10B is assembled.

[0075] Wooden units 10A and 10B, which have ceiling penetration wiring routes 34, ceiling wiring routes 35, and connection point wiring routes 36 created by indoor electrical wiring 33, are transported from the assembly plant to the facility site (installation site) by transport vehicles (transportation means). The first wooden unit 10A, which has been transported to the installation site, is lifted from the transport vehicle by a crane (not shown) and placed on a base (not shown) laid on the foundation rise of the foundation (raft foundation, strip foundation) of the installation site created by foundation work.

[0076] After the first wooden unit 10A is placed on the base, the wooden floor plate 12a (orthogonal laminated floor board) of the first wooden unit house 10A is connected and fixed to the base. The wooden floor plate 12a of the first wooden unit 10A and the base 71 are fixed together with vertical screws and diagonal screws. The second wooden unit 10B, which has been transported to the installation site, is lifted from the transport vehicle by a crane and placed on the base. The second wooden unit 10B is placed on the base adjacent to the first wooden unit 10A and spaced a predetermined distance apart from the first wooden unit 10A in the front-rear direction.

[0077] When the second wooden unit 10B is placed on the base 71, the second end edge 15 (rear end edge) of the wood-based ceiling plate 11a of the first wooden unit 10A and the first end edge 14 (front end edge) of the wood-based ceiling plate 11b of the second wooden unit 10B face each other at a distance in the front-rear direction, and the second end edge 22 (rear end edge) of the wood-based floor plate 12a of the first wooden unit 10A and the first end edge 21 (front end edge) of the wood-based floor plate 12b of the second wooden unit 10B face each other at a distance in the front-rear direction, creating a space between the adjacent first wooden unit 10A and the second wooden unit 10B.

[0078] Next, a ratchet-type pull-up jack (not shown) is placed between a first hook member (not shown) attached to the first side edge 23 of the wood-based floor plate 12a of the first wooden unit 10A and a second hook member (not shown) attached to the second side edge 24 of the wood-based floor plate 12b of the second wooden unit 10B. One end of a chain or wire rope connected to the ratchet-type pull-up jack is hooked onto the hook portion of the first hook member of the wood-based floor plate 12a of the first wooden unit 10A, and the other end of the chain or wire rope is hooked onto the hook portion of the second hook member of the wood-based floor plate 12b of the second wooden unit 10B.

[0079] A ratchet-type pull-up jack (not shown) is placed between a second hook member (not shown) attached to the first side edge 16 of the wood-based ceiling plate 11a of the first wooden unit 10A and a second hook member (not shown) attached to the second side edge 17 of the wood-based ceiling plate 11b of the second wooden unit 10B. One end of a chain or wire rope connected to the ratchet-type pull-up jack is hooked onto the hook portion of the first hook member of the wood-based ceiling plate 11a of the first wooden unit 10A, and the other end of the chain or wire rope is hooked onto the hook portion of the second hook member of the wood-based floor plate 12b of the second wooden unit 10B.

[0080] After hooking the chain or wire rope onto the hook portion of the first and second hook members, the handles of the ratchet-type pull jacks are manually rotated back and forth. As the handles of the ratchet-type pull jacks are rotated back and forth, the chain or wire rope is gradually pulled towards the ratchet-type pull jacks, thereby gradually moving the wooden floor plate 12b of the second wooden unit 10B forward in the front-rear direction, and the first end edge 21 of the wooden floor plate 12b of the second wooden unit 10B is gradually pulled towards the second end edge 22 of the wooden floor plate 12a of the first wooden unit 10A in the front-rear direction.

[0081] Furthermore, the wood-based ceiling plate 11b of the second wooden unit 10B gradually moves forward in the front-rear direction, and the first edge 21 of the wood-based ceiling plate 11b of the second wooden unit 10B is gradually pulled in the width direction toward the second edge 22 of the wood-based ceiling plate 11a of the first wooden unit 10A. The wood-based floor plate 12b of the second wooden unit 10B is pulled downward by sliding on the base.

[0082] As the first edge portion 21 (first and second side edges 23, 24) of the wood-based floor plate 12b of the second wooden unit 10B is pulled toward the second edge portion 22 (first and second side edges 23, 24) of the wood-based floor plate 12a of the first wooden unit 10A, the first end surface of the first edge portion 21 of the wood-based floor plate 12b of the second wooden unit 10B comes into contact with the second end surface of the second edge portion 22 of the wood-based floor plate 12a of the first wooden unit 10A, thereby connecting the second wooden unit 10B and the first wooden unit 10A.

[0083] As the first edge portion 14 (first and second side edges 16, 17) of the wood-based ceiling plate 11b of the second wooden unit 10B is pulled toward the second edge portion 15 (first and second side edges 16, 17) of the wood-based ceiling plate 11a of the first wooden unit 10A, the first end surface of the first edge portion 14 of the wood-based ceiling plate 11b of the second wooden unit 10B comes into contact with the second end surface of the second edge portion 15 of the wood-based ceiling plate 11a of the first wooden unit 10A, thereby connecting the second wooden unit 10B and the first wooden unit 10A. The pulling operation of the wood-based floor plate 12b of the second wooden unit 10B and the pulling operation of the wood-based ceiling plate 11b of the second wooden unit 10B are performed simultaneously.

[0084] After the first and second end faces of the first and second edges 21 and 22 of the wood-based floor plates 12a and 12b of the first and second wooden units 10A and 10B come into contact, and the first and second end faces of the first and second edges 14 and 15 of the wood-based ceiling plates 11a and 11b of the first and second wooden units 10A and 10B come into contact, the wood-based floor plate 12b (orthogonal laminated floor board) of the second wooden unit 10B is connected and fixed to the base.

[0085] Furthermore, the wood-based ceiling plates 11a and 11b (orthogonal laminated ceiling boards) of the first and second wooden units 10A and 10B are fixed to each other. The wood-based floor plate 12b of the second wooden unit 10B and the base are fixed with vertical screws and diagonal screws, and the wood-based ceiling plates 11a and 11b of the first and second wooden units 10A and 10B are fixed to each other with diagonal screws.

[0086] After fixing the wood-based floor plate 12b of the second wooden unit 10B to the base and fixing the wood-based ceiling plates 11a and 11b of the first and second wooden units 10A and 10B to each other, the switch lever of the ratchet-type pull-up jack is set to the reverse, and the jack is loosened by manually rotating the handle back and forth, the chain or wire rope is removed from the hook portion of the first and second hook members, and the first and second hook members are removed from the first and second side edges 16, 17, 23, and 24 of the wood-based floor plates 12a and 12b of the first and second wooden units 10A and 10B.

[0087] When the first wooden unit 10A and the second wooden unit 10B are connected, the beam-shaped sections 29 of the first and second wooden units 10A and 10B connect to each other, and the indoor electrical wiring insertion spaces 30 of these beam-shaped sections 29 connect, forming an indoor electrical wiring insertion space 30 that extends in one direction. By connecting multiple first and second wooden units 10A and 10B in the procedure described above, the wooden house 10 is installed (built) at the construction site. At the construction site, multiple wooden units 10a and 10B are lined up in one direction with the first wooden wall panel 13c of the first wooden unit 10A and the second wooden wall panel 13d of the second wooden unit 10B facing each other, creating a wooden house 10 with any layout that includes multiple rooms (living room, bedroom, guest room, children's room, dining kitchen, study, etc.).

[0088] Figure 9 is a top view of a wooden house 10 as an example, and Figure 10 is a side view of the wooden house 10. In Figure 9, the wooden ceiling plates 11a and 11b are removed, and in Figure 10, the wooden house 10 is shown in cross-section. After the wooden house 10 is installed at the construction site, the beam wiring process and the first distribution board connection process are carried out at the construction site.

[0089] A distribution board 39 is installed inside the wooden house 10. An electric meter 46 is installed on the outside of the wooden third wall panel 13c of the wooden house 10. A service cable (not shown) extending from a utility pole or an electrical wiring block manhole enters the electric meter 46. The distribution board 39 and the electric meter 46 are connected via a service entrance wiring 47. Indoor electrical wiring 33 for each room (electrical wiring for the living room, bedroom, guest room, children's room, dining kitchen, study, etc.) is connected to the distribution board 39.

The length dimension (total length from start to end) of the indoor electrical wiring 33 (dining kitchen electrical wiring 33) from the connection position wiring route 34 to the first distribution board connection route 38 in the dining kitchen (wooden units 10A, 10B) is adjusted to be a length that can be connected to the distribution board 39 but does not exceed the length of the distribution board 39. The length of these indoor electrical wires 33 (electrical wires 33 for the dining kitchen) is adjusted at the assembly plant.

[0096] The indoor electrical wiring 33 (study electrical wiring 33) extending from the ceiling penetration wiring route 34 of the study is pulled into the indoor electrical wiring insertion space 30 (inside) of the beam-shaped 29 to create a beam-shaped wiring route 37. Then, the indoor electrical wiring 33 connected to and extending from the beam-shaped wiring route 37 is wired toward the distribution board 39 installed in the wooden house 10, and the indoor electrical wiring 33 (study electrical wiring 33) is electrically connected to the distribution board 39 to create a first distribution board connection route 38 (first distribution board connection process). The length dimension (total length from start to end) of the indoor electrical wiring 33 (study electrical wiring 33) from the connection position wiring route 34 to the first distribution board connection route 38 in the study (wooden units 10A, 10B) is adjusted to be a length that can be connected to the distribution board 39 but does not exceed the length of the distribution board 39. The length of these indoor electrical wires 33 (electrical wires 33 for the study) is adjusted at the assembly plant.

[0097] The wiring method involves a connection position wiring process where each indoor electrical wire 33 connected to each lighting fixture 40, outlet 41, or switch 42 installed in each wooden unit 10A, 10B is wired to the wooden ceiling plates 11a, 11b of each wooden unit 10A, 10B to create a connection position wiring route 34; a ceiling wiring process where these indoor electrical wires 33 are wired on top of the wooden ceiling plates 11a, 11b of each wooden unit 10A, 10B to create a ceiling wiring route 35; and a ceiling penetration wiring process where these indoor electrical wires 33 are passed through wiring penetration holes 31 that penetrate the wooden ceiling plates 11a, 11b to create a ceiling penetration wiring route 36. These processes are performed at the assembly plant where the wooden units 10A, 10B are assembled. Therefore, the wiring work for creating the connection position wiring route 34, ceiling wiring route 35, and ceiling penetration wiring route 36 of the indoor electrical wires 33 can be omitted at the construction site of the wooden house 10, and the electrical wiring work at the construction site of the wooden house 10 can be significantly shortened.

[0098] The wiring method involves using the beam-shaped 29 created in the wooden unit 10A or wooden unit 10B to route the indoor electrical wiring 33 into the indoor electrical wiring insertion space 30 (inside) of the beam-shaped 29, creating a beam-shaped wiring route 37. The indoor electrical wiring 33 for each room (living room, bedroom, guest room, children's room, dining kitchen, study, etc.) is then routed from the beam-shaped wiring route 37 to the distribution board 39 via the distribution board's first connection route 38. This allows for easy consolidation of the indoor electrical wiring 33 for each room using the beam-shaped 29 of the wooden unit 10A or wooden unit 10B without requiring complex wiring work. The wiring method is such that the length of the indoor electrical wiring 33 from the connection point wiring path 34 in the wooden units 10A and 10B to the first connection path 38 of the distribution board is adjusted to be a length that can be connected to the distribution board 39 but does not exceed the length of the distribution board 39. Therefore, the indoor electrical wiring 33 of each room (each wooden unit 10A, 10B) can be easily connected to the distribution board 39 at the facility site, and waste of indoor electrical wiring caused by the length of the indoor electrical wiring exceeding the length of the distribution board can be eliminated.

[0099] The wiring method involves a beam-type wiring process to create a beam-type wiring route 37, which is carried out at the construction site of the wooden house 10. The distribution board first connection process to create a distribution board first connection route 38 is also carried out at the construction site of the wooden house 10. Since the electrical wiring work for the wooden house 10 is completed by the beam-type wiring process and the distribution board first connection process, it does not require much time or effort. As a result, the electrical wiring work for the indoor electrical wiring 33 (electrical wiring for the living room, bedroom, guest room, children's room, dining kitchen, study, etc.) in the wooden house 10 formed from each wooden unit 10A, 10B can be carried out quickly and efficiently, and the electrical wiring work can be completed within the scheduled construction period.

[0100] The wiring method is clear, including connection point wiring routes 34, ceiling wiring routes 35, ceiling penetration wiring routes 36, beam-type wiring routes 37, and the first distribution board connection route 38 in the wooden house 10. Therefore, replacement and repair work on each indoor electrical wiring 33 (living room electrical wiring, bedroom electrical wiring, guest room electrical wiring, children's room electrical wiring, kitchen electrical wiring, study electrical wiring, etc.) in each room (living room, bedroom electrical wiring, guest room electrical wiring, children's room electrical wiring, kitchen electrical wiring, study electrical wiring, etc.) of the wooden house 10 formed from each wooden unit 10A, 10B can be easily carried out, and the replacement and repair work on each indoor electrical wiring 33 can be carried out efficiently in a short amount of time.

[0101] Figure 11 is a top view of the second floor of a two-story wooden house 10, which is shown as another example, and Figure 12 is a side view of the two-story wooden house 10. In Figure 11, the wooden ceiling plates 11a and 11b of the second floor (upper floor) of the wooden house 10 are removed, and in Figure 12, the two-story wooden house 10 is shown in cross-section. After the two-story wooden house 10 is installed at the construction site, the beam wiring process, the first distribution board connection process, the EPS wiring process, and the second distribution board connection process are carried out at the construction site.

[0102] The connection position wiring process, ceiling wiring process, and ceiling penetration wiring process for the wooden units 10A and 10B that form the wooden house 10 (wooden unit house) on the first floor (lower floor) and second floor (upper floor) are carried out at the assembly plant (manufacturing plant) where the wooden units 10A and 10B are assembled (manufactured), as described above. The beam-type wiring process and the first distribution board connection process for the wooden house 10 on the first floor (lower floor) are carried out at the construction site. The EPS wiring process and the second distribution board connection process for the wooden house 10 on the second floor (upper floor) are carried out at the construction site.

[0103] An electrical conduit compartment 43 (EPS) is constructed within the wooden unit 10A. The electrical conduit compartment 43 is constructed in the assembly plant (manufacturing plant) where the wooden units 10A and 10B are assembled (manufactured). The electrical conduit compartment 43 consists of a frame made from wooden boards and a wooden door that opens and closes the electrical conduit compartment 43. The electrical conduit compartment 43 extends vertically from the beam-shaped frame 29 constructed in the wooden unit 10A on the second floor (upper floor) toward the wooden unit 10A on the first floor (lower floor), and its lower part is connected to the indoor electrical wiring insertion space 30 of the beam-shaped frame 29.

[0104] The installation procedure for the first-floor wooden house 10 is as previously described, so its explanation will be omitted. The beam-type wiring process and the first distribution board connection process for the first-floor (lower floor) wooden house 10 are as previously described, so their explanation will be omitted. The first wooden unit 10A for the second floor, which has been transported to the installation site by transport vehicle, is lifted from the transport vehicle by crane and placed on the wooden ceiling plate 11a (orthogonal laminated ceiling board) of the assembled house 10 of the first-floor first wooden unit 10A, which is connected to the foundation. After placing the first wooden prefabricated house 10A on the second floor on top of the first wooden prefabricated house 10A on the first floor, the wood-based floor plate 12a (orthogonal laminated floor board) of the first wooden prefabricated house 10A on the second floor is connected and fixed to the wood-based ceiling plate 11a (orthogonal laminated ceiling board) of the first wooden prefabricated house 10A on the first floor using vertical screws (vertical screws) or diagonal screws (diagonal screws).

[0105] The second wooden unit 10B on the second floor, which has been transported to the facility site by a transport vehicle, is lifted from the transport vehicle by a crane and placed on top of the second wooden unit 10B on the first floor. The second wooden unit 10B on the second floor is placed on top of the second wooden unit 10B on the first floor, adjacent to the first wooden unit 10A on the second floor and spaced a predetermined distance apart from the first wooden unit 10A on the second floor in the front-rear direction.

[0106] When the second wooden unit 10B is placed on top of the second wooden unit 10B on the first floor, the second edge 15 (rear edge) of the wood-based ceiling plate 11a of the first wooden unit 10A on the second floor and the first edge 14 (front edge) of the wood-based ceiling plate 11b of the second wooden unit 10B on the second floor are spaced apart and facing each other in the front-to-back direction, and the second edge 22 (rear edge) of the wood-based floor plate 12a of the first wooden unit 10A on the second floor and the first edge 21 (front edge) of the wood-based floor plate 12b of the second wooden unit 10B on the second floor are spaced apart and facing each other in the front-to-back direction, creating a space between the adjacent first wooden unit 10A and second wooden unit 10B on the second floor.

[0107] Next, a ratchet-type pull-in jack (not shown) is placed between a first hook member (not shown) attached to the first side edge 23 of the wood-based floor plate 12a of the first wooden unit 10A on the second floor and a second hook member (not shown) attached to the second side edge 24 of the wood-based floor plate 12b of the second wooden unit 10B on the second floor. One end of a chain or wire rope connected to the ratchet-type pull-in jack is hooked onto the hook portion of the first hook member of the wood-based floor plate 12a of the first wooden unit 10A on the second floor, and the other end of the chain or wire rope is hooked onto the hook portion of the second hook member of the wood-based floor plate 12b of the second wooden unit 10B on the second floor.

[0108] A ratchet-type pull-in jack (not shown) is placed between a second hook member (not shown) attached to the first side edge 16 of the wood-based ceiling plate 11a of the first wooden unit 10A on the second floor and a second hook member (not shown) attached to the second side edge 17 of the wood-based ceiling plate 11b of the second wooden unit 10B on the second floor. One end of a chain or wire rope connected to the ratchet-type pull-in jack is hooked onto the hook portion of the first hook member of the wood-based ceiling plate 11a of the first wooden unit 10A on the second floor, and the other end of the chain or wire rope is hooked onto the hook portion of the second hook member of the wood-based floor plate 12b of the second wooden unit 10B on the second floor.

[0109] After hooking the chain or wire rope onto the hook portion of the first and second hook members, the handles of the ratchet-type pull jacks are manually rotated back and forth. As the handles of the ratchet-type pull jacks are rotated back and forth, the chain or wire rope is gradually pulled towards the ratchet-type pull jacks, thereby gradually moving the wood-based floor plate 12b of the second wooden unit 10B on the second floor forward in the front-rear direction, and the first end edge 21 of the wood-based floor plate 12b of the second wooden unit 10B on the second floor is gradually pulled in the width direction toward the second end edge 22 of the wood-based floor plate 12a of the first wooden unit 10A on the second floor.

[0110] Furthermore, the wood-frame ceiling plate 11b of the second wooden unit 10B on the second floor gradually moves forward in the front-rear direction, and the first edge 21 of the wood-frame ceiling plate 11b of the second wooden unit 10B on the second floor is gradually pulled in the width direction toward the second edge 22 of the wood-frame ceiling plate 11a of the first wooden unit 10A on the second floor. The wood-frame floor plate 12b of the second wooden unit 10B is pulled downward by sliding over the wood-frame ceiling plate 11b of the second wooden unit 10B on the first floor.

[0111] As the first edge portion 21 (first and second side edges 23, 24) of the wood-based floor plate 12b of the second wooden unit 10B on the second floor is pulled toward the second edge portion 22 (first and second side edges 23, 24) of the wood-based floor plate 12a of the first wooden unit 10A on the second floor, the first end surface of the first edge portion 21 of the wood-based floor plate 12b of the second wooden unit 10B on the second floor comes into contact with the second end surface of the second edge portion 22 of the wood-based floor plate 12a of the first wooden unit 10A on the second floor, thereby connecting the second wooden unit 10B on the second floor and the first wooden unit 10A on the second floor.

[0112] As the first edge portion 14 (first and second side edges 16, 17) of the wood-based ceiling plate 11b of the second wooden unit 10B on the second floor is pulled toward the second edge portion 15 (first and second side edges 16, 17) of the wood-based ceiling plate 11a of the first wooden unit 10A on the second floor, the first end surface of the first edge portion 14 of the wood-based ceiling plate 11b of the second wooden unit 10B on the second floor comes into contact with the second end surface of the second edge portion 15 of the wood-based ceiling plate 11a of the first wooden unit 10A on the second floor, thereby connecting the second wooden unit 10B on the second floor and the first wooden unit 10A on the second floor. The pulling operation of the wood-based floor plate 12b of the second wooden unit 10B on the second floor and the pulling operation of the wood-based ceiling plate 11b of the second wooden unit 10B on the second floor are performed simultaneously.

[0113] After the first and second end faces of the first and second edges 21 and 22 of the wood-based floor plates 12a and 12b of the first and second wooden units 10A and 10B on the second floor come into contact, and the first and second end faces of the first and second edges 14 and 15 of the wood-based ceiling plates 11a and 11b of the first and second wooden units 10A and 10B on the second floor come into contact, the wood-based floor plate 12b (cross-laminated floor board) of the second wooden unit 10B on the second floor is connected and fixed to the wood-based ceiling plate 11b (cross-laminated floor board) of the second wooden unit 10B on the first floor.

[0114] Furthermore, the wood-based ceiling plates 11a and 11b (orthogonal laminated ceiling boards) of the first and second wooden units 10A and 10B on the second floor are fixed together. The wood-based floor plate 12b of the second wooden unit 10B on the second floor and the wood-based ceiling plate 11b of the second wooden unit 10B on the first floor are fixed together with vertical screws and diagonal screws, and the wood-based ceiling plates 11a and 11b of the first and second wooden units 10A and 10B on the second floor are fixed together with diagonal screws.

[0115] After fixing the wood-based floor plate 12b (orthogonal laminated floorboard) of the second wooden unit 10B on the second floor to the wood-based ceiling plate 11b (orthogonal laminated floorboard) of the second wooden unit 10B on the first floor, and fixing the wood-based ceiling plates 11a and 11b of the first and second wooden units 10A and 10B on the second floor to each other, the switch lever of the ratchet-type pull-up jack is set to the opposite side, and the jack is loosened by manually rotating the handle back and forth, the chain or wire rope is removed from the hook portion of the first and second hook members, and the first and second hook members are removed from the first and second side edges 16, 17, 23, and 24 of the wood-based floor plates 12a and 12b of the first and second wooden units 10A and 10B on the second floor.

[0116] When the first wooden unit 10A and the second wooden unit 10B on the second floor are connected, the beams 29 of the first and second wooden units 10A and 10B on the second floor connect to each other, and the indoor electrical wiring insertion spaces 30 of these beams 29 connect, forming an indoor electrical wiring insertion space 30 that extends in one direction. By connecting multiple first and second wooden units 10A and 10B in the procedure described above, a two-story wooden house 10 is installed (built) at the construction site. At the construction site, multiple first and second wooden units 10A and 10B are lined up in one direction with the first wooden wall panel of the first wooden unit 10A and the second wooden wall panel of the second wooden unit 10B facing each other, creating a two-story wooden house 10 with any layout that includes multiple rooms (living room, bedroom, guest room, children's room, dining kitchen, study, etc.) on the first and second floors.

[0117] As previously described, the indoor electrical wiring 33 of the beam-type wiring path 37 created by the beam-type wiring process passes through the indoor electrical wiring insertion space 30 of the beam-type 29 on the first floor, the indoor electrical wiring 33 extending from the beam-type wiring path 37 forms the distribution board first connection path 38, and the indoor electrical wiring 33 of the distribution board first connection path 38 is electrically connected to the distribution board 39. The beam-type wiring process and the distribution board first connection process for the wooden house 10 on the second floor (lower floor) are the same as those for the first floor (upper floor), so the explanation of those processes for the wooden house 10 on the second floor (lower floor) will be omitted by referring to the explanation of those processes for the first floor.

[0118] The wiring method involves first drawing the electrical wiring 33 (indoor electrical wiring 33) for the bedroom on the second floor (upper floor) into the indoor electrical wiring insertion space 30 of the beam-shaped 29 on the second floor to create a beam-shaped wiring route 37. Then, the electrical wiring 33 (indoor electrical wiring 33) for the bedroom, which is connected to and extends from the beam-shaped wiring route 37, is drawn into the electrical conduit compartment 43. The electrical wiring 33 for the bedroom is then routed through the electrical conduit compartment 43 from the second floor (upper floor) to the first floor (lower floor) to create an EPS wiring route 44 using the electrical wiring 33 for the bedroom (EPS wiring process).

[0119] The wiring method involves first drawing the electrical wiring 33 (indoor electrical wiring 33) for the children's room on the second floor (upper floor) into the indoor electrical wiring insertion space 30 of the beam-shaped 29 on the second floor to create a beam-shaped wiring route 37. Then, the electrical wiring 33 (indoor electrical wiring 33) for the children's room, which is connected to and extends from the beam-shaped wiring route 37, is drawn into the electrical conduit compartment 43. The electrical wiring 33 for the children's room is then routed through the electrical conduit compartment 43 from the second floor (upper floor) to the first floor (lower floor) to create an EPS wiring route 44 using the electrical wiring 33 for the children's room (EPS wiring process).

[0120] Next, the electrical wiring for the bedrooms 33 (indoor electrical wiring 33) and the electrical wiring for the children's rooms 33 (indoor electrical wiring 33), which are connected to the EPS wiring route 44 and extend from the EPS wiring route 44, are wired toward the distribution board installed in the wooden house 10. These electrical wirings for the bedrooms 33 and the electrical wirings for the children's rooms 33 are then electrically connected to the distribution board 39 to create the second distribution board connection route 45 (second distribution board connection process). The length dimensions (total length from start to end) of the electrical wiring for the bedrooms 33 (indoor electrical wiring 33) and the electrical wirings for the children's rooms 33 (indoor electrical wiring 33) from the connection point wiring route 34 to the second distribution board connection route 45 in the bedrooms, children's rooms, etc. on the second floor (wooden units 10A, 10B) are adjusted to be a length that can be connected to the distribution board 39 but does not exceed the length of the distribution board 39. The lengths of the electrical wiring 33 for the bedrooms (indoor electrical wiring 33) and the electrical wiring 33 for the children's rooms (indoor electrical wiring 33) are adjusted at the assembly plant.

[0121] The wiring method involves routing indoor electrical wiring 33, which is wired to the beam-type 29 of the wooden house 10 (wooden unit 10A, 10B) on the second floor (upper floor), to the electrical conduit compartment 41 (EPS) to create an EPS wiring route 44 that brings the indoor electrical wiring 33 down to the wooden house 10 on the first floor (lower floor). At the same time, the indoor electrical wiring 33 that is connected to the EPS wiring route 44 and extends from the EPS wiring route 44 is connected to the distribution board 39 to create a second distribution board connection route 45. This allows for the indoor electrical wiring 33 of each room on the second floor (wooden unit 10A, 10B) to be brought down from the second floor to the first floor in one go, without requiring complex wiring work, by utilizing the electrical conduit compartment 41 (EPS) that extends from the second floor to the first floor.

[0122] The wiring method allows the indoor electrical wiring 33 of each room on the second floor (each wooden unit 10A, 10B) to be routed to the distribution board 39 via the beam type 29 and the electrical conduit compartment 43 (EPS), and also allows the indoor electrical wiring 33 of each room on the second floor (each wooden unit 10A, 10B) to be connected together to the distribution board 39, and allows the indoor electrical wiring 33 of each room on the second floor (each wooden unit 10A, 10B) to be easily connected to the distribution board 39 at the facility site. The wiring method ensures that the length of the electrical wiring 33 for each room (each wooden unit 10A, 10B) from the connection point wiring route 34 to the second connection route 45 to the distribution board is adjusted so that the total length from the starting point to the ending point of the electrical wiring 33 for the bedrooms and children's rooms (wooden units 10A, 10B) on the second floor is long enough to connect to the distribution board 39 but does not exceed the length of the distribution board 39. This allows for easy connection of the indoor electrical wiring 33 for each room (each wooden unit 10A, 10B) to the distribution board 39 at the facility site, and eliminates wasted indoor electrical wiring due to the length of the indoor electrical wiring exceeding the length of the distribution board.

[0123] The wiring method involves connecting the indoor electrical wiring 33 of the wooden house 10 (wooden units 10A, 10B) on the second floor (upper floor) to the distribution board 39 via the beam 29 and electrical conduit compartment 43 (EPS) of the wooden house 10 (wooden units 10A, 10B) on the second floor (upper floor), thus completing the wiring work quickly and efficiently without requiring much time or effort. This allows the indoor electrical wiring work in the wooden house 10 formed from each wooden unit 10A, 10B on the second floor (upper floor) to be completed within the scheduled construction period.

[0124] The wiring method involves creating a connection point wiring path 34 by wiring indoor electrical wiring 33 between the connection points of each lighting fixture 40, each outlet 41, or each switch 42 in each room (wooden unit 10A, 10B) on the second floor (upper floor) and the wooden ceiling plates 11a, 11b of the second-floor wooden units 10A, 10B. The indoor electrical wiring 33 connected to the connection point wiring path 34 and extending from the connection point wiring path 34 is then wired over the wooden ceiling plates 11a, 11b of the second-floor wooden units 10A, 10B to create a ceiling wiring path 35.
