[0009] According to claim 2 as described above, even if the portion of the frame body (10 or 10C) to which the rafters (51, 52, 53, 54, 51A, 52A, 53A, 51B, 52B, 53B, or 54B) are joined rests on the lower support, the rafters (51, 52, 53, 54, 51A, 52A, 53A, 51B, 52B, 53B, or 54B) are exposed downward. Therefore, various components such as fire-resistant boards or fire-resistant ceiling materials can be attached to the rafters (51, 52, 53, 54, 51A, 52A, 53A, 51B, 52B, 53B, or 54B). Therefore, the floor panel (1 or 1A) is highly versatile.
[0010] According to claim 3, in the floor panel (1 or 1A) according to claim 1 or 2, The area between the fireproof board (41, 42, 43, 141, 142 or 143) and the frame body (10 or 10C) is open. A floor panel (1 or 1A) is provided, characterized in that:
[0011] According to claim 3 as described above, the area between the fire-resistant board (41, 42, 43, 141, 142 or 143) and the frame body (10 or 10C) is open, so that various processing can be performed on the periphery of the fire-resistant board (41, 42, 43, 141, 142 or 143) depending on the installation location of the floor panel (1 or 1A). Therefore, the floor panel (1 or 1A) is highly versatile.
[0012] According to claim 4, in the floor panel (1 or 1A) according to claim 1 or 2, The crosspiece (21, 22, 21A or 22B) protrudes from the edge of the fireproof board (41, 42, 43, 141, 142 or 143). A floor panel (1 or 1A) is provided, characterized in that:
[0013] According to claim 4, since the crosspieces (21, 22, 21A or 22B) extend beyond the edges of the fireproof boards (41, 42, 43, 141, 142 or 143), various components such as fireproof boards or fireproof ceiling materials can be attached to the crosspieces (21, 22, 21A or 22B). Therefore, the floor panel (1 or 1A) is highly versatile.
[0014] According to claim 5, in the floor panel (1 or 1A) according to claim 1 or 2, The number of the crosspieces (21, 22, 21A or 22B) is plural. A floor panel (1 or 1A) is provided, characterized in that:

[0016] According to the present invention, the floor panel has high versatility. [Brief explanation of the drawings]
[0017] [Figure 1] FIG. 1 is a plan view of a floor panel according to the first embodiment. [Figure 2] FIG. 2 is a cross-sectional view taken along line II-II shown in FIG. [Figure 3] FIG. 3 is a plan view of the floor panel of the second embodiment. [Figure 4] FIG. 4 is a cross-sectional view taken along line IV-IV shown in FIG. DETAILED DESCRIPTION OF THE INVENTION
[0018] Hereinafter, embodiments will be described with reference to the drawings. Features and technical effects of the embodiments will be understood from the following detailed description and drawings. However, the scope of the present invention is not limited to the embodiments disclosed below. Because the drawings are provided for illustrative purposes only, the scope of the present invention is not limited to the examples in the drawings.
[0019] ===First embodiment=== Fig. 1 is a plan view of the floor panel 1. Fig. 2 is a cross-sectional view taken along line II-II shown in Fig. 1. This floor panel 1 is a component of a wooden building with a wall structure that is assembled using a wood panel adhesive construction method. Figures 1 and 2 show the floor panel 1 in its state before it is assembled. The floor panel 1 is used as a structure that supports the weight and seismic forces of the building. The floor panel 1 can be used as a floor on the first floor or two or more floors of a building. In the manufacturing factory for floor panel 1, the floor panel 1 is manufactured with the surface shown in Figure 1 facing up. At the construction site of a wooden building, the floor panel 1 is installed with the surface shown in Figure 1 facing down.
[0020] The floor panel 1 comprises a wooden frame 10, wooden crosspieces 21, 22, a wooden surface material 31, fireproof boards 41, 42, 43, and wooden framing boards 51, 52, 53, 54.
[0021] The frame 10 is assembled into a rectangular frame shape. The frame 10 has frames 11 to 14. Both ends of the frame 11 are joined to one end of each of the frames 13 and 14 with a single rabbit joint using an adhesive, and both ends of the frame 12 are joined to the other end of each of the frames 13 and 14 with a single rabbit joint using an adhesive, screws, or both. Alternatively, both ends of the frame 11 may be butt-joined to one end of each of the frames 13 and 14 with an adhesive at the frame 11 front or frame 11 back, and both ends of the frame 12 may be butt-joined to the other end of each of the frames 13 and 14 with an adhesive, screws, or both.
[0022] Crosspieces 21 and 22 are arranged between and parallel to frame 13 and frame 14. Frame 13, crosspiece 21, crosspiece 22, and frame 14 are lined up in parallel at equal intervals in this order. One end of crosspiece 21 and 22 is joined to frame 11 with a dado joint by adhesive or screws, or both, and the other end of crosspiece 21 and 22 is joined to frame 12 with a dado joint by adhesive or screws, or both. Note that one end of crosspiece 21 and 22 may be butt-joined to frame 11 by adhesive or screws, or both, and the other end of crosspiece 21 and 22 may be butt-joined to frame 12 by adhesive or screws, or both.
[0023] The face material 31 is rectangular. The face material 31 is made of plywood. The face material 31 covers the area surrounded by the frame body 10 and is joined to the frame body 10 and the crosspieces 21 and 22 with adhesive, screws, or both. The outer edge of the face material 31 is aligned with the outer periphery of the frame body 10.
[0024] As described above, the assembly consisting of the frame 10, the crosspieces 21, 22 and the face material 31, that is, the portion of the floor panel 1 excluding the fireproof boards 41-43 and the joists 51-54, is also called a unit panel.
[0025] The fire-resistant boards 41 to 43 are rectangular. The fire-resistant boards 41 to 43 cover the area between the crosspieces 21 and 22 from the opposite side of the face plate 31 with respect to the crosspieces 21 and 22, and are joined to the crosspieces 21 and 22 with screws, adhesive, or both. The fire-resistant boards 41, 42, and 43 are arranged in order without any gaps from the frame 11 toward the frame 12. The fire-resistant boards 41 to 43 are spaced apart from the frame body 10 toward the inside of the frame body 10, and the area between the fire-resistant boards 41 to 43 and the frame body 10 is open. The crosspiece 21 protrudes from one edge of the fire-resistant boards 41 to 43 toward the frame 13, and the crosspiece 22 protrudes from the other edge of the fire-resistant boards 41 to 43 toward the frame 14. The fire-resistant boards 41 to 43 are made of fire-resistant reinforced gypsum boards containing gypsum and inorganic fibers such as glass fibers or glass cloth fibers.
[0026] The sill 51 is joined to the frame 11 with adhesive or screws, or both, between the end of the frame 13 and the end of the crosspiece 21. Both end faces of the sill 51 abut against the frame 13 and the crosspiece 21, respectively. The sill 52 is joined to the frame 11 with adhesive or screws, or both, between the end of the crosspiece 21 and the end of the crosspiece 22. Both end faces of the sill 52 abut against the crosspiece 21 and the crosspiece 22, respectively. The sill 53 is joined to the frame 11 with adhesive or screws, or both, between the end of the crosspiece 22 and the end of the frame 14. Both end faces of the sill 53 abut against the crosspiece 22 and the frame 14, respectively. The sill 54 is joined to the frame 14 between the frame 11 and the frame 12. Both end faces of the siding 54 abut against the siding 53 and the frame 12, respectively. These sidings 51 to 54 are spaced apart from the face material 31. The surfaces of the sidings 51 to 54 are flush with the surfaces of the frame body 10 and the crosspieces 21 and 22. The surfaces of the frame body 10 and the crosspieces 21 and 22 refer to the surfaces opposite the back surfaces of the frame body 10 and the crosspieces 21 and 22 to which the face material 31 is joined.
[0027] Since the fireproof boards 41 to 43 are joined to the crosspieces 21 and 22 at the manufacturing factory, the joining quality of the fireproof boards 41 to 43 is high. Also, there is no need to attach the fireproof boards 41 to 43 at the construction site. This contributes to reducing the workload at the construction site.
[0028] When installing the floor panel 1, the fireproof boards 41-43 are placed facing downward, and the frames 11, 14 rest on lower supports such as foundations, beams, girder panels, or wall panels. The frames 11, 14 are joined to the lower supports with adhesive, screws, or both. The frames 12, 13 are joined to the frames of adjacent floor panels with bolt and nut fasteners, adhesive, screws, or two or more of these. After the floor panel 1 is installed, multiple fireproof boards or fireproof ceiling materials are stretched around the fireproof boards 41-43, and these fireproof boards or fireproof ceiling materials are joined to the frames 12, 13, crosspieces 21, 22, and joists 51-54 with adhesive or screws. Even when the frames 11, 14 are placed on the lower support, the rough sidings 51 to 54 are exposed downward, and therefore the rough sidings 51 to 54 are used as joints for the fireproof board or fireproof ceiling material.
[0029] Since the frames 11 and 14 rest on the lower support, the stiles 51 to 53 are joined to the frame 11, and the stile 54 is joined to the frame 14. When the frame 12 rests on the lower support, multiple stiles are joined to the frame 12 in the same way that the stiles 51 to 53 are joined to the frame 11. When the frame 13 rests on the lower support, the stile is joined to the frame 13 in the same way that the stile 54 is joined to the frame 12. In other words, the stile is joined to at least one of the frames 11 to 14.
[0030] If the floor panel 1 is not placed on a lower support and the frames 11 to 14 are joined to the four floor panels surrounding the floor panel 1, the stiles do not need to be joined to any of the frames 11 to 14.
[0031] === Second embodiment === Fig. 3 is a plan view of the floor panel 1A, and Fig. 4 is a cross-sectional view taken along line IV-IV shown in Fig. 3. The floor panel 1A comprises wooden frames 10A and 10B, wooden crosspieces 21A, 22A, 21B and 22B, wooden facings 31A and 31B, fireproof boards 141, 142 and 143, and wooden framing members 51A, 52A, 53A, 51B, 52B, 53B and 54B.
[0032] In the same way as in the first embodiment, in which the unit panel is assembled from the frame body 10, the crosspieces 21 and 22, and the face material 31, the first unit panel is assembled from the frame body 10A, the crosspieces 21A and 22A, and the face material 31A, and the second unit panel is assembled from the frame body 10B, the crosspieces 21B and 22B, and the face material 31B. The sizes of the first and second unit panels in the second embodiment are the same as those of the unit panels in the first embodiment.
[0033] In the same way that the siding members 51 to 53 are joined to the frame 11 in the first embodiment, the siding members 51A to 53A are joined to the frame 11A, and the siding members 51B to 53B are joined to the frame 11B. In the same way that the siding member 54 is joined to the frame 14 in the first embodiment, the siding member 54B is joined to the frame 14B.
[0034] The long sides of the first unit panel and the second unit panel are joined together. That is, the frame 14A of the first unit panel is joined to the frame 13B of the second unit panel with bolt and nut fasteners, adhesive, or screws, or two or more of these. The end face of the frame 11A of the first unit panel is butt-joined to the end face of the frame 11B of the second unit panel with adhesive, screws, or both, and the end face of the frame 12A of the first unit panel is butt-joined to the end face of the frame 12B of the second unit panel with adhesive, screws, or both.
[0035] Because the joint between the first and second unit panels is rectangular, in this floor panel 1A, frames 11A, 11B, 12A, 12B, 13A, and 14B form a rectangular frame body 10C. Frames 14A and 13B run from frames 11A and 11B to frames 12A and 12B of frame body 10C, so frames 14A and 13B can also be called crosspieces.
[0036] The fire-resistant boards 141-143 are rectangular. The fire-resistant boards 141-143 cover the area between the crosspieces 21A and 22B from the opposite side of the face plates 31A and 31B with respect to the crosspieces 21A, 22A, 21B, and 22B and the frame members 14A and 13B, and are joined to the crosspieces 21A, 22A, 21B, and 22B and the frame members 14A and 13B with screws, adhesive, or both. The fire-resistant boards 141, 142, and 143 are arranged in order without any gaps from the frame members 11A and 11B toward the frame members 12A and 12B. These fire-resistant boards 141-143 are spaced apart from the frame 10C consisting of frames 11A, 11B, 12A, 12B, 13A, and 14B toward the inside of the frame 10C, and the area between these fire-resistant boards 141-143 and the frame 10C is open. Crosspiece 21A protrudes from one edge of the fire-resistant boards 141-143 toward frame 13A, and crosspiece 22B protrudes from the other edge of the fire-resistant boards 141-143 toward frame 14B. The fire-resistant boards 141-143 are made of fire-resistant reinforced gypsum board containing gypsum and inorganic fibers such as glass fiber or glass cloth fiber.
[0037] A protective adhesive tape 160 is attached to the face materials 31A and 31B so as to cover the boundary line between the face materials 31A and 31B. When the floor panel 1A is installed, the protective adhesive tape 160 is peeled off.
[0038] When installing floor panel 1A, fire-resistant boards 141-143 are placed facing downward, and frames 11A, 11B, and 14B are placed on the lower support. Frames 11A, 11B, and 14B are joined to the lower support with adhesive, screws, or both. Frames 13A, 12A, and 12B are joined to the frame of the adjacent floor panel with bolt and nut fasteners, adhesive, screws, or two or more of these. After installing floor panel 1A, multiple fire-resistant boards or fire-resistant ceiling materials are stretched around the fire-resistant boards 141-143, and these fire-resistant boards or fire-resistant ceiling materials are joined to frames 12A, 12B, 13A, 13B, and 14A, crosspieces 21A, 22A, 21B, and 22B, and joists 51A-53A, 51B-54B with adhesive or screws. Even when the frames 11A, 11B, 14B are placed on the lower supports, the rough joists 51A to 53A, 51B to 54B are exposed downward, and therefore the rough joists 51A to 53A, 51B to 54B are used as joints for the fireproof boards or fireproof ceiling material.
[0039] When the frames 12A and 12B are placed on the lower support, multiple frames are joined to the frames 12A and 12B in the same way that frames 51A to 53A are joined to the frame 11. When the frame 13A is placed on the lower support, the frame is joined to the frame 13A in the same way that frame 54 is joined to the frame 12B. In other words, the frame is joined to at least one side of the frame body 10C consisting of frames 11A, 11B, 12A, 12B, 13A, and 14B.
[0040] ===Summary=== (1) Since the fire-resistant boards 41 to 43, 141 to 143 are joined at the manufacturing factory, the joining quality of the fire-resistant boards 41 to 43, 141 to 143 is high and the workload at the construction site is reduced. Since the rough edgings 51 to 54, 51A to 53A, 51B to 54A are joined at the manufacturing factory, the joining quality of the rough edgings 51 to 54, 51A to 53A, 51B to 54A is high and the workload at the construction site is reduced.
[0041] (2) The crosspieces 21, 22 are spaced apart from the stiles 13, 14 inside the frame 10, parallel to the stiles 13, 14, and are laid between the stiles 11 and 12, and the fireproof boards 41-43 are joined to the crosspieces 21, 22, spaced apart from the frame 10 and inside, leaving open space around the fireproof boards 41-43. This allows various processing to be performed around the fireproof boards 41-43 depending on the installation location of the floor panel 1. This makes the floor panel 1 highly versatile. The same is true for the floor panel 1A.
[0042] (3) Even when the frames 11 and 14 are placed on the lower supports, the sidings 51 to 54 are exposed downward. Therefore, various components such as fireproof boards or fireproof ceiling materials can be attached to the sidings 51 to 54. Therefore, the floor panel 1 is highly versatile. The same is true for the floor panel 1A.
[0043] (4) The fire-resistant boards 41 to 43 are spaced apart from the frame body 10 toward the inside of the frame body 10, and the area between these fire-resistant boards 41 to 43 and the frame body 10 is open. Therefore, various processing can be performed on the periphery of the fire-resistant boards 41 to 43 depending on the installation location of the floor panel 1. Therefore, the floor panel 1 is highly versatile. The same is true for the floor panel 1A.
[0044] (5) Since the crosspieces 21 and 22 extend beyond the edges of the fireproof boards 41 to 43, various components such as fireproof boards or fireproof ceiling materials can be attached to the crosspieces 21 and 22. This makes the floor panel 1 highly versatile. The same is true for the floor panel 1A.
[0045] (6) Since the fire-resistant boards 41 to 43 are joined to the plurality of crosspieces 21 and 22, the fire-resistant boards 41 to 43 are stable.
[0046] (7) Wood is used as a component of floor panels 1 and 1A. The energy used from production to disposal and disposal of wood is less than the energy used from production to disposal and disposal of metal or concrete materials. Therefore, floor panels 1 and 1A contribute to the realization of a decarbonized society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and to the achievement of the Sustainable Development Goals (SDGs).
[0047] (8) The above-disclosed embodiments have been made for the purpose of illustration and example only, and are not intended to limit the scope of the present invention, which should be interpreted by the terms of the claims. [Explanation of symbols]
