Description

[Technical Field]

[0001] The present invention relates to a sauna room and a trailer house. [Background technology]

[0002] Conventionally, there is a technique for forming a ventilation layer on the indoor side of a sauna room (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 61-039542 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if a ventilation layer is formed on the indoor side of the sauna room, there is a risk that the humidity of the air passing through the ventilation layer may damage the walls of the sauna room.

[0005] The present invention has been made in consideration of the above circumstances, and aims to improve the moisture resistance of the walls of sauna rooms. [Means for solving the problem]

[0006] The invention described in claim 1 is, for example, as shown in FIGS. 4 to 7, A sauna room 10, A moisture-proof sheet 81 is attached from the indoor side of the wall (inner wall 19) of the sauna room 10 to the ceiling, A wall finishing material 83 is attached to the surface of the moisture-proof sheet 81 on the wall side via a vertical furring strip 82. A ceiling finishing material 84 is attached to the surface of the moisture-proof sheet 81 on the ceiling side. The space between the moisture-proof sheet 81 on the wall side and the wall finishing material 83 is a ventilation layer. At the joint between the wall (inner wall 19) and the ceiling, the wall finishing material 83 and the ceiling finishing material 84 are arranged at a distance from each other, and the space between the wall finishing material 83 and the ceiling finishing material 84 is the first air vent.

[0007] According to the invention described in claim 1, a moisture-proof sheet 81 is attached from the indoor side of the wall of the sauna room 10 (inner wall 19) to the ceiling, and a ventilation layer is formed between the wall-side moisture-proof sheet 81 and the wall finishing material 83. At the joint with the ceiling, the wall finishing material 83 and the ceiling finishing material 84 are spaced apart, and a first ventilation port is formed between the wall finishing material 83 and the ceiling finishing material 84. This allows air to circulate inside the sauna room 10 without stagnating near the walls. Furthermore, because the wall side of the ventilation layer is covered with the moisture-proof sheet 81, the moisture-proof properties of the walls of the sauna room 10 are improved, and damage to the walls of the sauna room 10 due to moisture from the air passing through the ventilation layer can be prevented.

[0008] The invention described in claim 2 is, for example, as shown in FIG. At the joint between the wall (inner wall 19) and the ceiling, the upper end of the wall finishing material 83 is positioned at a distance from the moisture-proof sheet 81 on the ceiling side, and the side end of the ceiling finishing material 84 is positioned at a distance from the upper end of the wall finishing material 83, and the space between the upper end of the wall finishing material 83 and the side end of the ceiling finishing material 84 is the first air vent.

[0009] According to the invention described in claim 2, at the joint between the wall (inner wall 19) and the ceiling, the upper end of the wall finishing material 83 is spaced apart from the moisture-proof sheet 81 on the ceiling side, and the side end of the ceiling finishing material 84 is spaced apart from the upper end of the wall finishing material 83, and the space between the upper end of the wall finishing material 83 and the side end of the ceiling finishing material 84 is defined as a first ventilation opening. Therefore, the moisture-proof sheet 81 can be made less visible to people inside the sauna room 10.

[0010] The invention described in claim 3 is, for example, as shown in FIG. The lower end of the wall finishing material 83 is positioned at a distance from the floor finishing material 76 attached to the floor of the sauna room 10, and a second air vent is formed between the lower end of the wall finishing material 83 and the floor finishing material 76.

[0011] According to the invention described in claim 3, the lower end of the wall finishing material 83 is positioned at a distance from the floor finishing material 76 attached to the floor of the sauna room 10, and a second air vent is formed between the lower end of the wall finishing material 83 and the floor finishing material 76, so that air can circulate between the wall finishing material 83 of the sauna room 10 and the moisture-proof sheet 81.

[0012] The invention described in claim 4 is, for example, as shown in FIG. A joist 85 is provided along the wall of the sauna room 10, and a base board 86 to which the ceiling finishing material 84 is fixed is attached to the underside of the joist 85. The side end of the base board 86 is arranged with a gap between it and the wall (inner wall 19). The moisture-proof sheet 81 is attached to the indoor surface of the wall (interior wall 19), the underside of the joist 85, the side end surface of the base board 86, and the underside of the base board 86. The positions of the side ends of the ceiling finishing material 84 and the base board material 86 are aligned, and a groove G is formed at the joint between the wall (inner wall 19) and the ceiling, and the upper end of the wall finishing material 83 is positioned in this groove G.

[0013] According to the invention described in claim 4, the moisture-proof sheet 81 is attached to the indoor surface of the wall (interior wall 19), the underside of the joist 85, the side end faces of the base board material 86, and the underside of the base board material 86, and at the joint between the wall (interior wall 19) and the ceiling, the upper end of the wall finishing material 83 is placed in a groove G formed by the aligned side ends of the ceiling finishing material 84 and the side ends of the base board material 86 and the underside of the joist 85. This makes it even more difficult for people inside the sauna room 10 to see the moisture-proof sheet 81, improving its appearance.

[0014] The invention described in claim 5 is, for example, as shown in FIG. A waterproof sheet 77 is attached from the underside of the floor finishing material 76 to the lower end of the indoor surface of the wall (inner wall 19), and the lower end of a moisture-proof sheet 81 is overlapped and joined to the upper end of the waterproof sheet 77.

[0015] According to the invention described in claim 5, a waterproof sheet 77 is attached from the underside of the floor finishing material 76 to the lower end of the indoor surface of the wall (interior wall 19), and the lower end of a moisture-proof sheet 81 attached from the indoor surface of the wall (interior wall 19) to the ceiling is overlapped and joined to the upper end of this waterproof sheet 77. Therefore, a sauna room 10 with high waterproof and moisture-proof properties can be realized.

[0016] The invention described in claim 6 is, for example, as shown in Figs. 4 and 5, The wall (inner wall 19) is made of architectural wood panels.

[0017] According to the sixth aspect of the invention, in a sauna room 10 whose walls (inner walls 19) are made of architectural wood panels, the walls of the sauna room 10 can be prevented from being damaged by moisture.

[0018] The invention described in claim 7 is, for example, as shown in FIGS. 1 to 8, The trailer house 1 is provided with the sauna room 10 according to any one of claims 1 to 6.

[0019] According to the seventh aspect of the invention, the sauna room 10 can be moved, and therefore the sauna room 10 can be moved and installed in a desired location. [Effects of the Invention]

[0020] According to the present invention, it is possible to improve the moisture resistance of the walls of the sauna room. [Brief explanation of the drawings]

For example, the width of the trailer house 1 is within 2.5 meters, the length of the trailer house 1 is within 12 meters, and the height of the trailer house 1 is within 3.8 meters. By obtaining a special permit, the size or weight of the trailer house 1 may exceed the limits set forth in the road transport vehicle safety standards.

[0025] The trailer house 1 includes a chassis 2, a sauna room 10, a changing room 20, a deck 30, and a tarp 40.

[0026] The chassis 2 is also called a bogie. The chassis 2 has a base 3 and left and right wheels 4. The left and right wheels 4 are attached to the left and right sides of the base 3, respectively, and the base 3 is supported above an installation surface 99 by the wheels 4. The base 3 is supported above the installation surface 99 by a support structure such as a support base 5. The support structure can be easily removed from the chassis 2 without tools. The wheels 4 may be prevented from rolling by a wheel stopper. The chassis 2 has a coupler attached to the front end of the base 3, and the chassis 2 can be connected to a towing vehicle by the coupler.

[0027] The sauna room 10 is installed on the base 3 of the chassis 2 and is located near the front end of the base 3. The changing room 20 is installed on the base 3 and is located near the rear end of the base 3. The deck 30 is installed on the base 3 and is located between the sauna room 10 and the changing room 20. A staircase may be provided from the installation surface 99 to the left or right end of the deck 30. A handrail may be erected on the left or right end of the deck 30. A table may be placed or installed on the deck 30. A bench may be placed or installed on the deck 30.

[0028] The sauna room 10 has a floor 17 (see FIG. 5) on its bottom surface, a rear wall 11 on its rear surface, a left side wall 12 (see FIG. 5) on its left side surface, a front wall 13 on its front surface, a right side wall 14 on its right side surface, and a roof 15 on its top surface. The floor 17 is installed on a base frame 61 laid on a stand 3. In this embodiment, the sauna room 10 is a wooden house assembled using a wood panel adhesive construction method, and the rear wall 11, left side wall 12, front wall 13, right side wall 14, roof 15, and floor 17 are made of architectural wood panels. The architectural wood panels include a rectangular frame formed by assembling four wooden frames into a rectangular frame shape and wooden facings attached to one or both sides of the rectangular frame. The architectural wood panels may also include one or more wooden crosspieces attached to the inside of the rectangular frame. The construction wood panels may have a heat insulating material such as glass wool, rock wool, or foam resin filled inside the rectangular frame. The lower end of the rear wall 11 is joined to the rear end of the floor 17, and the rear wall 11 stands on the rear end of the floor 17. The lower end of the left side wall 12 is joined to the left end of the floor 17, and the left side wall 12 stands on the left end of the floor 17. The lower end of the front wall 13 is joined to the front end of the floor 17, and the front wall 13 stands on the front end of the floor 17. The lower end of the right side wall 14 is joined to the right end of the floor 17, and the right side wall 14 stands on the right end of the floor 17.

[0029] The rear wall 11 has an opening and a door 16, such as a hinged door, a sliding door, or a double sliding door, installed in the opening. The deck 30 can be accessed from inside the sauna room 10 through the door 16. Note that a fixture other than a door, such as a sliding window, may be installed in the opening of the rear wall 11 instead of the door 16.

[0030] The sauna room 10 is also equipped with a heating device (not shown) that heats the air inside the sauna room 10. The heating device is provided, for example, on the front end surface of the sauna room 10. A window 110 is also installed on the right side wall 14 of the sauna room 10.

[0031] The changing room 20 has a floor at its bottom, a rear wall 21 at its rear, a right side wall 24 at its right side, a front wall 23 at its front, a left side wall at its left side, and a roof 25 at its top. The floor of the changing room 20 is placed on a base frame 62 laid on a platform 3. The lower end of the rear wall 21 is joined to the rear end of the floor, and the rear wall 21 stands upright at the rear end of the floor. The left side wall is joined to the left end of the floor, and the left side wall stands upright at the left end of the floor. The lower end of the front wall 23 is joined to the front end of the floor, and the front wall 23 stands upright at the front end of the floor. The right side wall 24 is joined to the right end of the floor, and the right side wall 24 stands upright at the right end of the floor.

[0032] The front wall 23 has an opening and a door 26, such as a hinged door, a sliding door, or a double sliding door, installed in the opening. The deck 30 can be accessed from inside the dressing room 20 through the door 26. Note that a type of fixture other than a door, such as a sliding window, may be installed in the opening of the front wall 23 instead of the door 26.

[0033] The roofs 15, 25 of the sauna room 10 and the changing room 20 are single-pitch roofs that slope downward to the right or left. The roofs 15, 25 may not be single-pitch roofs, but may be flat roofs or gable roofs. If the roofs 15, 25 are gable roofs, the ridges of the roofs 15, 25 extend forward and backward or left and right. The eaves and overhangs of the roofs 15, 25 are very short.

[0034] The tarp 40 is placed above the deck 30, spanning between the rear of the sauna room 10 and the front of the changing room 20. The tarp 40 is a waterproof membrane material, so it prevents water from passing through. The tarp 40 is water-repellent. In one example, the water-repellent properties of the tarp 40 are achieved by applying a silicone-based or fluorine-based water-repellent agent to the tarp 40. In another example, the water-repellent properties of the tarp 40 are achieved by providing the surface of the tarp 40 with fine irregularities.

[0035] (underfloor structure) FIG. 2(a) is a plan view showing the underfloor structure of the sauna room 10, the changing room 20, and the deck 30 installed on the pedestal 3 of the chassis 2. FIG. 2(b) is a side view showing the underfloor structure of the sauna room 10, the changing room 20, and the deck 30 installed on the pedestal 3 of the chassis 2. In FIG. 2(a), L1 indicates the outer wall line of the sauna room 10, L2 indicates the outer wall line of the changing room 20, L3 indicates the outer perimeter line of the deck 30, and L4 indicates the outer perimeter line of the pedestal 3. As shown in FIGS. 2(a) and 2(b), a base frame 61 serving as the foundation of the sauna room 10, a base frame 62 serving as the foundation of the changing room 20, and an underfloor portion 63 of the deck 30 are attached to the pedestal 3. The pedestal 3 is provided with four twist locks 31 (see FIG. 5) on the front side for attaching the sauna room 10, and four twist locks 31 on the rear side for attaching the changing room 20.

[0036] The base frame 61 is composed of a short-side frame member 61a that is long along the short side of the sauna room 10, and long-side frame members 61b and 61c that are long along the long side of the sauna room 10. In this embodiment, the short-side frame member 61a and the long-side frame member 61b are made of wood, for example. By using wood for the short-side frame member 61a and the long-side frame member 61b, the weight of the base frame 61 can be reduced. The long-side frame member 61c, located at the front end of the chassis 2, is made of steel, and pipes extending from the sauna room 10 or steel brackets supporting the pipes are fixed thereto by welding. By using steel for the long-side frame member 61c, the width can be made narrower than wood, making it easier to secure space for arranging pipes or brackets, and also making it possible to fix the pipes or brackets by welding. Furthermore, by providing this steel long side frame member 61c at the front end of the chassis 2 (that is, providing the piping at the front end of the chassis 2), the workability of piping work can be improved and safety during road travel can be ensured. The materials of the short-side frame member 61a and the long-side frame members 61b and 61c are not limited to those mentioned above.

[0037] Wooden floor beam fixing hardware 61d is joined to both ends of each of the short-side frame members 61a and the long-side frame members 61b, and connecting hardware 61e is rigidly joined to the other ends of each of the wooden floor beam fixing hardware 61d by bolts, welding, or the like. That is, the short-side frame member 61a and the long-side frame member 61b are connected via the wooden floor beam fixing hardware 61d and the connecting hardware 61e. Furthermore, connecting hardware 61e joined to the short-side frame member 61a is joined to both ends of the long-side frame member 61c. That is, the short-side frame member 61a and the long-side frame member 61c are connected via the wooden floor beam fixing hardware 61d and the connecting hardware 61e. As a result, the base frame 61 forms a rectangular frame with connecting hardware 61e at its four corners. Note that the short-side frame member 61a and the long-side frame members 61b and 61c are bolted to the frame 3 as needed, so multiple bolt through holes are formed.

[0038] 3A and 3B are diagrams mainly illustrating the configuration of the metal joint 61e (62e), where (a) is a side view and (b) is a cross-sectional view. Figures 3A and 3B show the metal joint 61e (62e) on the right rear side as an example. The connecting metal fitting 61e is a rectangular box with one side open. As shown in Figure 3(a), the interior of the connecting metal fitting 61e is divided into two spaces, and a square tube member 611 is disposed in one space. Furthermore, during the assembly work of the sauna room 10, components such as bolts are inserted through the opening of the connecting metal fitting 61e, or hands, tools, etc. are inserted into the other space.

[0039] The square tube member 611 is used when loading and unloading the sauna room 10 onto the chassis 2 or the like using a jacking device. Specifically, for example, one end of a rod-shaped member is inserted into the square tube member 611 at each of the multiple connecting metal fittings 61e of the base frame 61, and the other end of each rod-shaped member is lifted with a jacking device, thereby jacking up the sauna room 10. This makes it possible to lift the sauna room 10 with a jacking device even in situations where it is not possible to place a jacking device directly below the sauna room 10.

[0040] As shown in Figure 3(a), the connecting metal fitting 61e is positioned so that its opening faces outward (toward the side of the chassis 2) and the square tube member 611 is positioned on the short-side frame member 61a side. An upper circular hole 612 is formed in the top surface of the connecting metal fitting 61e, penetrating the top surface. A stud bolt 56 that connects the base frame 61 and the sauna room 10 main body is passed through this upper circular hole 612. The stud bolt 56 is fixed in place by a nut 56a and a nut 56b.

[0041] As shown in Figure 3(b), a long hole 613 is formed in the underside of the metal joint 61e, penetrating the underside. This long hole 613 is used to insert the protrusion of the twist lock 31 provided on the stand 3 to attach the sauna room 10 to the stand 3 of the chassis 2 (see Figure 5). When attaching the sauna room 10 to the pedestal 3, first, the sauna room 10 is lifted up with a crane or the like (or raised with a jack or the like), and the sauna room 10 is placed on the pedestal 3 with the positions of the multiple long holes 613 of the sauna room 10 aligned with the positions of the multiple twist locks 31 provided on the pedestal 3. After that, the protrusions of the twist locks 31 inserted into the long holes 613 are rotated to switch the twist locks 31 from the released state to the locked state. By performing this switching operation for each of the multiple twist locks 31, the sauna room 10 can be fixed to the pedestal 3. In addition, a lower circular hole 614 is formed in the lower surface of the joining hardware 61e, penetrating the lower surface, and a nut 614a is fixed by welding or the like inside the joining hardware 61e (on the upper surface of the lower surface of the joining hardware 61e) at a position corresponding to the lower circular hole 614.

[0042] The base frame 62 is configured with short-side frame members 62a that are long along the short side direction of the sauna room 10, and long-side frame members 62b that are long along the long side direction of the sauna room 10. In this embodiment, the short-side frame members 62a and the long-side frame members 62b are made of wood, for example. By using wood for the short-side frame members 62a and the long-side frame members 62b, the weight of the base frame 61 can be reduced. However, the materials of the short-side frame members 62a and the long-side frame members 62b are not limited to those mentioned above.

[0043] Wooden floor beam fixing hardware 62d is joined to both ends of each of the short-side frame members 62a and the long-side frame members 62b, and connecting hardware 62e is rigidly joined to the other ends of each of the wooden floor beam fixing hardware 62d by bolts, welding, or the like. In other words, the short-side frame members 62a and the long-side frame members 62b are connected via the wooden floor beam fixing hardware 62d and the connecting hardware 62e. This forms a rectangular frame body with connecting hardware 62e at the four corners of the base frame 62. Note that the short-side frame members 62a and the long-side frame members 62b are bolted to the frame 3 as needed, so they have multiple bolt through holes formed in them.

[0044] The metal joint 62e is a rectangular box with one side open. As shown in Figure 3(a), the interior of the metal joint 62e is divided into two spaces, and a square tube member 621 is disposed in one space. Furthermore, during the assembly work of the dressing room 20, components such as bolts are inserted through the opening of the metal joint 62e, or hands, tools, etc. are inserted into the other space.

[0045] The square tube member 621 is used when loading and unloading onto the chassis 2 etc. of the changing room 20 using a jack device. Loading and unloading onto the chassis 2 etc. of the changing room 20 is similar to loading and unloading onto the chassis 2 etc. of the sauna room 10 described above, except that the square tube member 621 is used instead of the square tube member 611, so the same explanation will be used.

[0046] As shown in Figure 3(a), the connecting metal member 62e is positioned so that its opening faces outward (toward the side of the chassis 2) and the rectangular tube member 621 is positioned on the short-side frame member 62a side. An upper circular hole 622 is formed in the top surface of the connecting metal member 62e, penetrating the top surface. A stud bolt 56 that connects the base frame 62 and the changing room 20 is passed through this upper circular hole 622. The stud bolt 56 is fixed by a nut 56a and a nut 56b.

[0047] 3(b), a long hole 623 is formed in the underside of the metal joint 62e, penetrating the underside. This long hole 623 is used to attach the changing room 20 to the stand 3 of the chassis 2 by inserting the protrusion of the twist lock 31 provided on the stand 3. The method of attaching the changing room 20 to the stand 3 is the same as the above-mentioned explanation of the method of attaching the sauna room 10 to the stand 3, except that the long hole 623 is used instead of the long hole 613, so the explanation will be used here. In addition, a lower circular hole 624 that penetrates the lower surface of the joining metal 62e is formed, and a nut 624a is fixed by welding or the like inside the joining metal 62e (on the upper surface of the lower surface of the joining metal 62e) at a position corresponding to the lower circular hole 624.

[0048] As shown in FIG. 2(a), the underfloor 63 of the deck 30 is configured by bridging a plurality of joists 63b that are perpendicular to the joists 63a on top of a plurality of joists 63a. The joists 63a and joists 63b are made of, for example, steel. The joists 63a and joists 63b are fixed to the frame 3 with bolts or the like. As shown in FIG. 2(b), a floor material 63c of the deck 30 is laid on top of the joists 63b. The floor material 63c of the deck 30 has drainage holes (not shown). In addition, decorative panels 63d are attached to the side surfaces of the deck 30.

[0049] (Sauna room structure) Fig. 4 is a vertical cross-sectional view of the vicinity of the front end portion of the upper right side of the sauna room 10 (near AA in Fig. 2(a)). Fig. 5 is a vertical cross-sectional view of the vicinity of the front end portion of the lower part of the sauna room 10 (near AA in Fig. 2(a)). As shown in FIG. 5, a floor 17 and a half base 18 are provided on the base frame 61 of the sauna room 10. The half base 18 is, for example, a square timber and is provided on the periphery of the floor 17. Pillars 87 (see FIGS. 2(b) and 3(a)) are arranged at the four corners of the floor 17 and half base 18, and the rear wall 11, left side wall 12, front wall 13, and right side wall 14 are each fastened with screws or bolts between adjacent pillars 87. Each pillar 87 is in contact with the vertical frame of the adjacent wall, and these vertical frame members are fastened with screws or bolts. In addition, a connecting metal piece 88 is provided at the bottom of each pillar 87. The connecting metal piece 88 is a rectangular box-shaped piece with open sides and has a through-hole 88a on the bottom surface. The stud bolt 56 mentioned above is passed through the through-hole 88a from the upper circular hole 612 of the joint metal fitting 61e and penetrates the joint between the floor 17 and the half base 18, and the upper end of the stud bolt 56 is fixed with a nut 56b. This fixes the sauna room 10 body (the part above the floor 17) to the base frame 61. In the following description, the inner surfaces of the rear wall 11, left side wall 12, front wall 13, and right side wall 14 of the sauna room 10 will be collectively referred to as the inner walls 19.

[0050] As shown in Figure 5, multiple plywood panels 71-73, a roof drain 74, foam insulation 75, etc. are arranged on the floor 17, forming a water gradient. A floor finishing material 76 is layered on top of the plywood 71. Sour roll, for example, can be used as the floor finishing material 76. A waterproof sheet 77 made of PVC or the like is attached from the underside of the floor finishing material 76 to the lower part of the interior wall 19, and the lower end of a moisture-proof sheet 81 is overlapped on the upper end of the waterproof sheet 77 and joined with acrylic tape or the like.

[0051] As shown in Figures 4 and 5, inside the sauna room 10, a moisture-proof sheet 81 is attached from the inner wall 19 to the ceiling. For example, a polyethylene sheet or the like can be used as the moisture-proof sheet 81. A sauna wall finishing material 83 is attached to the surface of the moisture-proof sheet 81 on the inner wall 19 side via vertical furring strips 82, and a ventilation layer is formed between the moisture-proof sheet 81 on the inner wall 19 side and the wall finishing material 83. A sauna ceiling finishing material 84 is attached to the surface of the moisture-proof sheet 81 on the ceiling side. At the junction between the wall and ceiling (the junction between the wall finishing material 83 and the ceiling finishing material 84), the upper end of the wall finishing material 83 is spaced apart from the moisture-proof sheet 81 on the ceiling side, and the side end of the ceiling finishing material 84 is spaced apart from the upper end of the wall finishing material 83. As a result, a vent (first vent) that serves as an outlet for air that has passed between the moisture-proof sheet 81 on the interior wall 19 side and the wall finishing material 83 is formed between the upper end of the wall finishing material 83 and the side end of the ceiling finishing material 84. In addition, the lower end of the wall finishing material 83 is disposed at a distance from the floor finishing material 76. As a result, a vent (second vent) that serves as an inlet for air to the ventilation layer is formed between the lower end of the wall finishing material 83 and the floor finishing material 76. The ventilation structure is designed to avoid the sash of the window 110 and the sash of the door 16.

[0052] As shown in Figure 4, a joist 85 is provided at the edge of the interior wall 19 of the ceiling. A base board 86, to which a ceiling finishing material 84 is fixed, is attached to the underside of the joist 85. The side edges of the base board 86 are spaced apart from the interior wall 19, and the moisture-proof sheet 81 is attached across the interior wall 19, the underside of the joist 85, the side edge faces of the base board 86, and the underside of the base board 86. The positions of the side edges of the ceiling finishing material 84 and the side edges of the base board 86 are aligned, forming a groove G where the moisture-proof sheet 81 is attached at the joint between the interior wall 19 and the ceiling, and the upper end of the wall finishing material 83 is positioned in this groove G. Here, as shown in Figure 6, it is possible to place the moisture-proof sheet 81 directly from the inner wall 19 to the underside of the base board material 86 without providing a groove G, but by providing a groove G at the joint between the inner wall 19 and the ceiling as shown in Figure 4, the moisture-proof sheet 81 becomes less visible to people inside the sauna room 10, thereby improving the appearance.

[0053] 7, the side edges of the base board material 86 to which the moisture-proof sheet 81 is attached and the ceiling finishing material 84 may be in contact with the interior wall 19, and the upper end of the wall finishing material 83 may be lowered to leave a gap between it and the ceiling finishing material 84, thereby forming a vent (first vent) that serves as an exit for air that has passed between the moisture-proof sheet 81 on the interior wall 19 side and the wall finishing material 83. This also makes it difficult for people inside the sauna room 10 to see the moisture-proof sheet 81, improving its appearance.

[0054] The ventilation structure described above allows air to circulate inside the sauna room 10 without stagnating near the walls. In addition, the wall side of the ventilation layer is covered with moisture-proof sheet 81, improving moisture resistance and preventing damage to the walls of the sauna room 10 (rear wall 11, left side wall 12, front wall 13, right side wall 14) due to moisture in the air passing through the ventilation layer.

[0055] (Chassis Modification) Conventionally, a chassis is provided with twist locks at the four corners of the frame to prevent cargo such as containers or residential units from moving. However, simply fastening the four corners with twist locks poses structural and durability problems when carrying two independent cargoes (such as residential units) as in the above embodiment. Therefore, in the above embodiment, the chassis 2 is provided with four twist locks 31 for attaching the sauna room 10 and four twist locks 31 for attaching the changing room 20. The configuration of the chassis 2 is not particularly limited as long as it is provided with a total of eight twist locks 31 as described above, but for example, the configuration of the chassis 2A shown in FIG. 8 may be applied.

[0056] Fig. 8(a) is a plan view of the chassis 2A, and Fig. 8(b) is a side view of the chassis 2A. As shown in Figs. 8(a) and 8(b), the chassis 2A is configured to include a coupling portion 91 for coupling with a towing vehicle, a platform 92 for placing a load, and wheels 93. The platform 92 corresponds to the platform 3 in the chassis 2 shown in Fig. 1, and the wheels 93 correspond to the wheels 4 in the chassis 2 shown in Fig. 1.

[0057] The stand 92 is configured with a plurality of long-side frame members 92a extending in the front-rear direction of the chassis 2A and a plurality of short-side frames 92b extending in the left-right direction of the chassis 2A. The stand 92 is also provided with four sets of support members 92e-92h spanning the left and right sides, with twist locks 94 attached to both ends of each. Support member 92e is provided at the front end of the stand 92. Support member 92f is provided at a position corresponding to the length of the side of a unit (e.g., sauna room 10) to be placed on the front side of the stand 92. Support member 92h is provided at the rear end of the stand 92. Support member 92g is provided at a position corresponding to the length of the side of a unit (e.g., changing room 20) to be placed on the rear side of the stand 92.

[0058] The support members 92e-92g are, for example, rectangular steel tubes, and include members 921e-921h that bridge between the two sets of long-side frame members 92a in the center of the frame 92, and members 922e-922g to which twist locks 94 are attached at both ends. Each twist lock 94 has a protrusion 94a and a base 94b, and the base 94b is attached to the members 922e-922h via flat steel 95. The twist lock 94 attached to member 922e has a front end joined to the short-side frame 92b on the front end side of the frame 92. The twist lock 94 attached to member 922h has a rear end joined to the short-side frame 92b on the rear end side of the frame 92. Support members 96 extending in the front-to-rear direction of the rack 92 are attached to the rear side of the connection between member 922e and the flat steel 95 attached thereto, the front side of the connection between member 922h and the flat steel 95 attached thereto, both the front and rear sides of the connection between member 922f and the flat steel 95 attached thereto, and both the front and rear ends of the connection between member 922g and the flat steel 95 attached thereto. A support member 97 is attached to each support member 96 perpendicular to its extension direction, and the end of each support member 97 opposite to the support member 96 is attached to the outer long-side frame member 92a of the rack 92. That is, each twist lock 94 is supported by support members 92e to 92g and is also supported by the outer long-side frame member 92a via support members 96 and 97. This allows two independent loads (such as residential units) to be placed on the rack 92 without any problems in terms of structure or durability. The support member 96 is, for example, a square steel pipe, and the support member 97 is, for example, an L-shaped steel.

[0059] Furthermore, the outer long-side frame member 92a is cut to form an opening between the connection portions between the two support members 97 located on both sides of the twist locks 94 (twist locks 94 supported by members 921f and 921g) provided at locations other than the four corners of the frame 92. This opening allows easy access to the twist locks 94 from the side of the frame 92, making it easy to check, for example, whether the protrusions 94a are fixed in a direction that will prevent them from coming off an object placed on the frame 92. Furthermore, this opening allows easy access to the inside of the metal joint 61e when the sauna room 10 described above is placed on the frame 92, facilitating installation of the sauna room 10, such as installing the stud bolts 56.
