[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-039593 Summary of the Invention [Problem to be solved by the invention]

[0004] In the floor structure of Patent Document 1, a builder installs floor joists at a construction site, and then installs particle boards on the floor joists. Next, workers install finishing members on the particle boards. There is a need for a technology that can reduce the burden on builders at construction sites.

[0005] This specification provides a technology that can reduce the burden on builders at construction sites. [Means for solving the problem]

[0006] In a first aspect disclosed in the present specification, the floor panel may include a finishing member on a flat plate and a support portion extending downward from a lower surface of the finishing member.

[0007] According to the above-mentioned configuration, since the floor panel has a finishing member, the builder only needs to install the floor panel in the foundation at the construction site. Therefore, the burden on the builder at the construction site can be reduced.

[0008] In a second aspect, in the above-mentioned first aspect, the support portion may include a first positioning portion provided at a first end on a first side of a specific direction that is a direction perpendicular to the up-down direction, and a second positioning portion provided at a second end on a second side opposite the first side of the specific direction and corresponding to the first positioning portion.

[0009] Consider a situation in which multiple floor panels are installed side by side. With the above configuration, when arranging multiple floor panels in a specific direction, the first positioning portion and the second positioning portion can be used to easily position the multiple floor panels.

[0010] In a third aspect, in the first aspect described above, the first end of the support portion on a first side in a specific direction that is perpendicular to the up-down direction may be inclined from the first side toward a second side opposite the first side in the specific direction as it goes from top to bottom.

[0011] Consider a situation where multiple floor panels are installed side by side. In this case, the floor panel that is positioned furthest to the first side among the multiple floor panels can be easily installed within the foundation.

[0012] In a fourth aspect, in the third aspect, the support portion may include a second positioning portion provided at a second end on a second side opposite to the first side in the specific direction.

[0013] According to the above configuration, the second positioning portion can be used to facilitate positioning of the floor panel.

[0014] In a fifth aspect, in any one of the first to fourth aspects, the finishing member may be made of cork or flooring material.

[0015] In a sixth aspect, in any one of the first to fifth aspects, the finishing member may not have a side tongue. [Brief explanation of the drawings]

[0017] (Example) The building 2 in Figure 1 is a building constructed using the wood-frame construction method. The building 2 is a three-story apartment building. Below, the construction method of the building 2 will be explained, and details of the building 2 will be described.

[0018] As shown in Figure 2, the construction method for building 2 includes a unit manufacturing process carried out in a factory and a unit assembly process carried out at the construction site. The unit manufacturing process includes a wall panel unit manufacturing process, a reference column manufacturing process, a first floor panel manufacturing process, a floor panel unit manufacturing process, a gable wall unit manufacturing process, and a shed unit manufacturing process. A rainproofing process may also be carried out at the construction site.

[0019] (Unit manufacturing process: Figures 3 to 18) The unit manufacturing process carried out in the factory will be described with reference to FIGS.

[0020] (Wall panel unit manufacturing process: Figure 3) A wall panel unit manufacturing process for manufacturing a wall panel unit will be described with reference to Fig. 3. The wall panel unit manufacturing process is a process for manufacturing a wall panel unit for an exterior wall.

[0021] First, in S2, a frame unit including a plurality of frames is manufactured. For example, the plurality of frames includes an upper frame, a lower frame, and a plurality of vertical frames connecting the upper frame and the lower frame.

[0022] In S4, the frame unit manufactured in S2 is compressed in the vertical direction. The following steps are performed with the frame unit in a compressed state. In a modified example, step S4 can be omitted.

[0023] In S10, the wall panel is fabricated by attaching the outer board to the frame unit. In one example, the outer board is plywood.

[0024] In S12, an anti-termite treatment is carried out by spraying or applying an agent to the wall panel produced in S10.

[0025] In S14, electrical materials (such as a power outlet box and CD pipe) are attached to the wall panel. In the case of a wall panel unit that does not have electrical materials, step S14 is omitted.

[0026] At S16, insulation is installed inside the outer boards of the wall panel.

[0027] At S18, a waterproof sheet is attached to the outer surface of the outer board of the wall panel.

[0028] In step S20, an inner board is attached to the inner surface of the wall panel frames. In one example, the inner board is gypsum board.

[0029] In S22, siding boards are attached to the wall panels. Specifically, the siding boards are attached to the outside of the waterproof sheet. Note that furring strips are placed between the waterproof sheet and the siding boards. This leaves a gap between the waterproof sheet and the siding boards.

[0030] In S24, fixtures (doors, windows, etc.) are attached to the wall panel. Note that if a wall panel unit without fixtures is produced, the step of S24 is omitted.

[0031] One wall panel unit is produced by the above steps S10 to S24.

[0032] (Wall panel unit; Figures 4-6) An example of a wall panel unit manufactured by the above-mentioned wall panel unit manufacturing process will be described with reference to Figures 4 to 6. Note that the directions in the following figures are given for ease of understanding and do not represent actual directions. Also, the right side of Figures 4 to 6 shows the inside of the building, and the left side shows the outside of the building.

[0033] The first wall panel unit 10, which does not have electrical materials or fixtures, will be described with reference to Fig. 4. The manufacturing process of the first wall panel unit 10 does not include steps S14 and S24 in Fig. 3.

[0034] As shown in Figure 4, the first wall panel unit 10 includes a wall panel 12, a waterproof sheet 14, an inner board 16, and a siding board 18. The wall panel 12 includes a frame unit 20 and an outer board 22. The frame unit 20 includes an upper frame 24, a lower frame 26 positioned below the upper frame 24, and a plurality of vertical frames 28 connecting the upper frame 24 and the lower frame 26. The upper frame 24 and the lower frame 26 extend in the front-to-rear direction. The multiple vertical frames 28 extend in the up-down direction. The outer board 22 is fixed to the outer surfaces of the upper frame 24, the lower frame 26, and the multiple vertical frames 28.

[0035] The inner board 16 is fixed to the inner surfaces of the upper frame 24 and the multiple vertical frames 28. The lower end of the inner board 16 is located higher than the lower end of the outer board 22. The front ends of the inner board 16 and the outer board 22 are located forward of the front ends of the upper frame 24 and the lower frame 26. The rear ends of the inner board 16 and the outer board 22 are located rearward of the rear ends of the upper frame 24 and the lower frame 26.

[0036] 5 and 6, a second wall panel unit 30 that does not have electrical materials but has a fixture 40 will be described. The manufacturing process of the second wall panel unit 30 does not include the step S14 in FIG.

[0037] As shown in FIG. 5, the second wall panel unit 30 includes a wall panel 32, a waterproof sheet 34, an inner board 36, a siding board 38, and a door and window frame 40 (see FIG. 6). The wall panel 32 includes a frame unit 42 and an outer board 44. The frame unit 42 includes an upper frame 50, a lower frame 52 positioned below the upper frame 50, a plurality of first vertical frames 54 connecting the upper frame 50 and the lower frame 52, a lintel (not shown), and a plurality of second vertical frames (not shown) connecting the upper frame 50 and the lintel. The plurality of first vertical frames 54 and the plurality of second vertical frames extend in the vertical direction. The outer board 44 is fixed to the outer surfaces of the upper frame 50, the lower frame 52, the plurality of first vertical frames 54, the lintel, and the plurality of second vertical frames. The inner board 36 is fixed to the inner surfaces of the upper frame 50, the lower frame 52, the plurality of first vertical frames 54, the lintel, and the plurality of second vertical frames. Openings 44A and 36A are formed in the outer board 44 and the inner board 36, respectively. The fittings 40 shown in FIG. 6 are placed in the openings 44A and 36A. The rear ends of the outer board 44 and the inner board 36 are located further rearward than the rear ends of the upper frame 50 and the lower frame 52.

[0038] As described above, wall panel units of various shapes are manufactured by the wall panel unit manufacturing process of FIG.

[0039] (Standard column manufacturing process: Figure 7) A reference column manufacturing process for manufacturing a reference column will be described with reference to Fig. 7. The reference column is a column for positioning a wall panel unit at a construction site.

[0040] In step S30, a central pillar of a predetermined length is manufactured. In this embodiment, the central pillar is a rectangular pillar with a square cross section.

[0041] In S32, one or more side columns are attached to the side of the central column. The side columns are quadrangular columns with a rectangular cross-sectional area. The cross-sectional area of ​​the side columns is approximately half that of the central column.

[0042] In S34, marking is performed on the central column to determine the vertical position of the wall panel unit.

[0043] One reference column is produced by steps S30 to S34 above.

[0044] (Reference column 60; Figure 8) An example of a reference post manufactured by the reference post manufacturing process of FIG. 7 will be described with reference to FIG.

[0045] The reference column 60 comprises a central column 62 and two side columns 64, 66. A mark 62A is marked on the central column 62. As an example, when the reference column 60 is fixed to the foundation, the mark 62A indicates the position of the upper end of the wall panel unit for the first floor.

[0046] The side pillar 64 is attached to the right side of the central pillar 62, and the side pillar 66 is attached to the left side of the central pillar 62. The upper ends of the side pillars 64 and 66 are located lower than the upper end of the central pillar 62. The lower ends of the side pillars 64 and 66 are located lower than the lower end of the central pillar 62.

[0047] The positions and number of side columns attached to the central column will vary depending on the positions and number of wall panel units assembled to the base column. For example, wall panel units are placed on the right and left sides of base column 60. Therefore, side columns 64 and 66 are attached to the right and left sides of central column 62.

[0048] (Floor finishing panel manufacturing process: Figure 9) A floor finishing panel manufacturing process for manufacturing a floor finishing panel will be described with reference to Fig. 9. The floor finishing panel is used for the floor of the first floor.

[0049] In S40, the finishing member finished to a predetermined shape is connected to the support portion, thereby producing a single floor finishing panel. As an example, the finishing member is a flooring member or cork material.

[0050] (Floor finishing panels; Figures 10 to 13) An example of a floor finishing panel manufactured by the floor finishing panel manufacturing process of FIG. 9 will be described with reference to FIGS.

[0051] As shown in FIG. 10, the first floor finishing panel 80 comprises a flat finishing member 82 and two support members 84. The finishing member 82 is made of flooring or cork. The finishing member 82 does not have a so-called tongue and groove. The two support members 84 are connected to the underside of both left and right ends of the finishing member 82. The support members 84 are connected to the underside of the finishing member 82 by adhesive, fasteners, etc. The longitudinal direction of the support member 84 is along the front-to-rear direction, and the lateral direction is along the up-down direction. The support member 84 comprises a protrusion 84A provided at the rear end of the support member 84 and a recess 84B provided at the front end of the support member 84. The protrusion 84A has a shape corresponding to the recess 84B.

[0052] The second floor finishing panel 90 will be described with reference to Figure 11. The second floor finishing panel 90 differs in the configuration of the support portion 94 from the configuration of the support portion 84 of the first floor finishing panel 80. Specifically, the support portion 94 of the second floor finishing panel 90 has a recess 94B provided at the front end of the support portion 94. As shown in Figure 13, the recess 94B has a shape corresponding to the protrusion 84A of the first floor finishing panel 80. Furthermore, the rear end of the support portion 94 of the second floor finishing panel 90 is inclined forward as it goes from top to bottom. In other words, the support portion 94 does not have a protrusion.

[0053] The third floor finishing panel 100 will be described with reference to Figure 12. The third floor finishing panel 100 differs in the configuration of the support portion 104 from the configuration of the support portion 84 of the first floor finishing panel 80. Specifically, the support portion 104 of the third floor finishing panel 100 has a convex portion 104A provided at the rear end of the support portion 104. As shown in Figure 13, the convex portion 104A has a shape corresponding to the concave portion 84B of the first floor finishing panel 80. Furthermore, the front end of the support portion 104 of the third floor finishing panel 100 is inclined rearward as it goes from top to bottom. In other words, the support portion 104 does not have a concave portion.

[0054] (Floor panel unit manufacturing process: Figure 14) A floor panel unit manufacturing process for manufacturing a floor panel unit will be described with reference to Fig. 14. The floor panel unit is used for floors above the second floor.

[0055] In S50, the floor panel is assembled. The floor panel includes an outer frame that defines the outer shape of the floor panel, an inner frame that is disposed inside the outer frame, and plywood sections that are disposed on the outer frame and the inner frame.

[0056] In S52, heat insulating material is attached to the underside of the plywood portion of the floor panel.

[0057] In S54, a waterproof sheet is attached to the insulation of the floor panel.

[0058] In S56, gypsum board is attached to the upper surface of the plywood portion of the floor panel.

[0059] One floor panel unit is produced by steps S50 to S56 above.

[0060] (Floor panel unit; Figure 15) With reference to FIG. 15, an example of a floor panel unit manufactured by the floor panel unit manufacturing process of FIG. 14 will be described.

[0061] As shown in Figure 15, the floor panel unit 120 includes a floor panel 122, a heat insulating material (not shown), a waterproof sheet (not shown), and a gypsum board 124. The floor panel 122 includes an outer frame 130, an inner frame (not shown), and a plywood section 132. The heat insulating material and the waterproof sheet are provided on the underside of the plywood section 132. The gypsum board 124 is provided on part of the upper surface of the plywood section 132. The part of the upper surface of the plywood section 132 where the gypsum board 124 is not provided is the part where the wall panel unit is to be placed.

[0062] (Gable wall unit manufacturing process: Figure 16) The gable wall unit manufacturing process for manufacturing the gable wall unit will be described with reference to Fig. 16. The gable wall unit defines the outer wall of the building 2 at the top.

[0063] At S60, the gable wall panels are produced.

[0064] In S62, gypsum board is attached to the gable wall panel manufactured in S60, thereby completing the gable wall unit.

[0065] (Gable wall panel; Figure 17) An example of a gable wall panel manufactured in the gable wall unit manufacturing process of FIG. 16 will be described with reference to FIG.

[0066] As shown in Figure 17, the gable wall panel 140 comprises an upper frame 142, a lower frame 144 positioned below the upper frame 142, multiple vertical frames 146 connecting the upper frame 142 and the lower frame 144, and multiple first roof panel support frames 148. Each of the multiple first roof panel support frames 148 is fixed between two adjacent vertical frames 146 in the front-to-rear direction. The multiple vertical frames 146 slope upward from the rear to the front. The gable wall unit is completed by attaching gypsum board to the outside of this gable wall panel 140.

[0067] In addition, in some gable wall panels, multiple first roof panel support frames extend parallel to the horizontal plane.

[0068] (Shed unit manufacturing process: Figure 18) 18 and 19, the cabin unit manufacturing process for manufacturing the cabin unit will be described.

[0069] At S70, a shed unit is produced by assembling multiple frames.

[0070] (Shed unit; Figure 19, Figure 20) 19 and 20, an example of a cabin unit manufactured by the cabin unit manufacturing process of FIG. 18 will be described.

[0071] As shown in FIG. 19 , the cabin unit 160 includes a front frame 162, a rear frame 164 positioned rearward of the front frame 162, multiple horizontal frames 166, multiple second roof panel support frames 168, and multiple connecting frames 170. Note that in FIG. 19 , the multiple horizontal frames 166 are hatched for clarity. The cabin unit 160 includes the front frame 162, the rear frame 164, the multiple horizontal frames 166, the second roof panel support frame 168, and multiple connecting frames 170. The multiple horizontal frames 166 connect the front frame 162 and the rear frame 164. The multiple connecting frames 170 connect the upper surfaces of the horizontal frames 166 in the left-right direction. The multiple second roof panel support frames 168 connect the front frame 162 and the rear frame 164. As shown in FIG. 20 , the upper surface of the second roof panel support frame 168 slopes upward from the rear to the front. A roof panel (not shown) is placed on the upper surface of the second roof panel support frame 168. Although not shown, the shed unit 160 further includes a left frame and a right frame that is positioned rearward of the left frame.

[0072] Each unit manufactured in the unit manufacturing process is transported to the construction site using a truck, etc. As an example, wall panel units are transported to the construction site packed in racks.

[0073] (Unit assembly process: Figure 1, Figures 21 to 26) The unit assembly process carried out at a construction site will be described with reference to Figures 1 and 20 to 25. The unit assembly process is carried out after the foundation 200 (see Figure 23) has been constructed. For ease of viewing, in Figures 22, 25, and 26, only some of the reference columns and some of the wall panel units are labeled with reference numerals. Furthermore, waterproof sheets and siding boards are omitted from Figures 23 and 24.

[0074] In S100, a plurality of reference columns for the first floor are fixed onto a foundation 200. As shown in Fig. 22, some of the reference columns (e.g., 202, 206) are installed at the corners of the building. Also, some of the reference columns for the first floor (e.g., 204) are placed between two reference columns for the first floor.

[0075] 23, the reference pillar 202 is fixed to the foundation 200 via the support part 201. The support part 201 is fixed onto the foundation 200. In a modified example, the reference pillar 202 may be fixed directly to the foundation 200.

[0076] In S102 of Fig. 21, a plurality of wall panel units for the first floor are positioned and temporarily fixed to the foundation 200. Specifically, the horizontal positioning of the wall panel units is performed using a plurality of reference columns for the first floor, and the vertical positioning of the wall panel units is performed using the marks on the reference columns. As a result, the plurality of wall panel units are placed on the foundation 200, as shown in Fig. 22.

[0077] A method for positioning a wall panel unit 208 using a reference post 204 will be described with reference to Figures 23 and 24. As shown in Figure 23, the reference post 202 includes a central post 220, a side post 222 attached to the right side of the central post 220, and a side post 224 attached to the front side of the central post 220. The reference post 204 includes a central post 226, a side post 228 attached to the right side of the central post 226, and a side post 230 attached to the left side of the central post 226. The central posts 220 and 226 are marked with indices 220A and 226A. The wall panel unit 208 also includes a wall panel 240 and an inner board 242. Note that the waterproof sheet, inner board, and siding board are omitted from Figure 24 for clarity. The wall panel 240 includes a frame unit 244 and an outer board 246. The frame unit 244 includes an upper frame 248 (see FIG. 24), a lower frame 250, and a plurality of vertical frames 252. The front-to-rear dimensions of the upper frame 248 and the lower frame 250 are approximately the same as the front-to-rear dimension of the central pillar 220.

[0078] First, as shown in FIG. 24 , the position of the wall panel unit 208 is adjusted so that the side column 230 of the reference column 204 is positioned between the inner board 242 and the outer board 246 of the wall panel unit 208. This positions the wall panel unit 208 in the front-to-rear direction. Next, the position of the wall panel unit 208 is adjusted so that the right surface of the upper frame 248 of the wall panel unit 208 abuts against the side column 230 of the reference column 204. This positions the wall panel unit 208 in the left-to-right direction. In this state, the left surface of the upper frame 248 of the wall panel unit 208 abuts against the side column 222 of the reference column 202. Next, the position of the wall panel unit 208 is adjusted so that the upper end of the wall panel unit 208 coincides with the mark 226A of the reference column 204. This positions the wall panel unit 208 in the up-down direction. In this manner, the wall panel unit 208 is positioned. In Figures 23 and 24, for the sake of clarity, we have described the case where one wall panel unit is placed between two reference columns, but two or more wall panel units may be placed between two reference columns.

[0079] As shown in FIG. 22, members other than the plurality of wall panel units 206 are then temporarily fixed onto the foundation 200.

[0080] Next, in S110 of FIG. 21, a plurality of floor panel units 260 (see FIG. 25) for the second floor are assembled above the plurality of wall panel units and the like.

[0081] In S112, reference columns (e.g., 262, 264, 266) are connected to each of a plurality of reference columns fixed to the foundation 200. A mark indicating the position of the upper end of the wall panel unit (e.g., 268) for the second floor is marked on the newly connected reference columns.

[0082] In S114, the multiple wall panel units for the second floor are positioned and assembled (temporarily fastened) to the floor panel unit for the second floor. As a result, for example, the wall panel unit 268 for the second floor is placed above the wall panel unit 208 for the first floor. Then, as shown in Fig. 25, the members for the second floor other than the multiple wall panel units are also assembled (temporarily fastened) to the floor panel unit 260.

[0083] In S120 of FIG. 21, a plurality of floor panel units 290 (see FIG. 26) for the third floor are assembled above a plurality of wall panel units for the second floor, etc.

[0084] In S122, reference columns (e.g., 292, 294, 296) are connected to each of the multiple reference columns connected in S112. A mark indicating the position of the top end of the wall panel unit (e.g., 298) for the third floor is marked on the newly connected reference columns.

[0085] In S124, a plurality of wall panel units for the third floor are positioned, and the wall panel units are assembled (temporarily fastened) to the floor panel unit 290 for the third floor. Then, as shown in FIG. 26, members for the third floor other than the plurality of wall panel units are also assembled to the floor panel unit 260.

[0086] In S130, the gable wall units, shed units, and roof panels are assembled. Specifically, multiple gable wall units are assembled above multiple third-floor wall panel units. Additionally, shed units are assembled below the multiple gable wall units. Furthermore, roof panels are assembled on the top surface of the shed units.

[0087] After that, after the installation of piping and other components is completed, multiple floor finishing panels are placed on the first floor. In this way, the assembly of each unit manufactured in the factory is completed, and the building 2 in Figure 1 is completed.

[0088] (Rain curing process; Figure 27) The rain curing process will be described with reference to Fig. 27. The rain curing process is carried out every time work for the day is completed, or when it rains during work.

[0089] For example, assume that rain falls on the construction site after S102 in FIG. 21 is completed. In this case, as shown in FIG. 27, a rain protection sheet 400 is placed above the building under construction using multiple reference pillars (e.g., 202, 204, 206, 208). A crane or the like is used to place the rain protection sheet 400. Multiple weights 402 are attached to the ends of the rain protection sheet 400. In FIG. 27, the weights 402 are directly attached to the rain protection sheet 400, but the weights 402 may also be attached to the rain protection sheet 400 via string-like members. Note that the placement of the rain protection sheet 400 above the building under construction may also be performed manually by a builder. The size of the rain protection sheet 400 is preferably such that the bottom end of the rain protection sheet 400 is positioned slightly above the bottom end of the wall panel unit.

[0090] (Effects of this embodiment) As described above, the floor finishing panel 80 (an example of a "floor panel") includes a flat finishing member 82 and support portions 84, 86 extending downward from the lower surface of the finishing member 82.

[0091] According to the above-mentioned configuration, since the floor finishing panel 80 has the finishing member 82, the builder only needs to install the floor finishing panel 80 in the foundation at the construction site. Therefore, the burden on the builder at the construction site can be reduced.

[0092] In addition, the first support portions 84, 86 of the first floor finishing panel 80 include a convex portion 84A (an example of a "first positioning portion") provided at the rear end (an example of a "first end") in the fore-and-aft direction (an example of a "specific direction"), and a concave portion 84B provided at the front end (an example of a "second end") and corresponding to the convex portion 84A.

[0093] According to the above configuration, when arranging a plurality of floor panels in a specific direction, the positioning of the plurality of floor panels can be facilitated by utilizing the convex portions 84A and the concave portions 84B.

[0094] Furthermore, the rear ends of the support portions 94, 96 of the second floor finishing panel 90 are inclined from the rear side to the front side as they go from top to bottom.

[0095] As described above, the second floor finishing panel 90, which is arranged at the rearmost side among the plurality of floor panels, can be easily installed within the foundation.

[0096] Additionally, the support portions 94, 96 of the second floor finishing panel 90 include recesses 94B provided at their front ends.

[0097] According to the above configuration, the second floor finishing panel 90 can be easily positioned by utilizing the recess 94B.
