[Technical Field]

[0001] The present invention relates to a knockdown room constructed by combining a plurality of panels and an assembly kit for the knockdown room. [Background technology]

[0002] Conventionally, there have been known prefabricated rooms constructed by joining together a plurality of panels (see, for example, Patent Documents 1 and 2). The prefabricated room of Patent Document 1 has a box-shaped storage section in which a front panel, a right side panel, a left side panel, a rear panel, a ceiling panel, and a bottom panel are joined together by welding, screws, or the like. The prefabricated room of Patent Document 2 is formed into a hollow box shape by combining together a plurality of panels. In the prefabricated room, the notches on the edges of adjacent panels are combined and joined together. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3219377 [Patent Document 2] Japanese Patent Application Publication No. 2019-2266 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional prefabricated rooms such as those described in Patent Documents 1 and 2, there is only one way to assemble the panels, and the location of the entrance / exit is fixed. Therefore, if the location of the entrance / exit needs to be changed to suit the installation environment, or if a user requests a change in the location of the entrance / exit on-site, an assembly kit for a room with a different entrance / exit location must be separately procured and delivered.

[0005] The present invention has been made to solve the above-mentioned problems, and has as its object to provide a prefabricated room with a simple structure that allows the arrangement of entrances and exits to be freely changed, and an assembly kit for the same. [Means for solving the problem]

[0006] One embodiment of the present invention provides an assembled room having peripheral walls, a top wall, and a bottom wall, which are constructed by combining multiple panels having plate-like plate portions and flange portions extending vertically from each of the four edges of the plate portions. The peripheral walls have a door panel, four peripheral wall panels, and at least one peripheral wall extension panel, and the door panel, peripheral wall panel, and peripheral wall extension panel are all equal in height and thickness, the width of the peripheral wall panel is longer than the width of the peripheral wall extension panel by the thickness of the door panel, and the width of the door panel is a natural number multiple of the width of the peripheral wall extension panel, and the peripheral wall panel has a connecting flange extending vertically inward from the edge of one of the two flange portions arranged along the height direction.

[0007] An assembly kit according to one embodiment of the present invention is an assembly kit for an assembly-type room constructed by combining a plurality of panels each having a plate-shaped plate portion and a flange portion extending vertically from each of the four edges of the plate portion, and the peripheral wall components include a door panel, four peripheral wall panels, and a plurality of peripheral wall extension panels, the door panel, peripheral wall panel, and peripheral wall extension panels being equal in height and thickness, the width of the peripheral wall panel being longer than the width of the peripheral wall extension panel by the thickness of the door panel, the width of the door panel being a natural number multiple of the width of the peripheral wall extension panel, and the peripheral wall panel having a connecting flange extending vertically inward from the edge of one of the two flange portions arranged along the height direction. [Effects of the Invention]

[0008] The present invention has a peripheral wall including a door panel, four peripheral wall panels, and at least one peripheral wall extension panel, all of which are equal in height and thickness, and the width of the peripheral wall panel is longer than the width of the peripheral wall extension panel by the thickness of the door panel, and the width of the door panel is an integer multiple of the width of the peripheral wall extension panel, and the peripheral wall panel has a connecting flange. Therefore, by combining panels with a simple structure, the arrangement of the entrance and exit of the prefabricated room can be freely changed. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Embodiment 1 An example of the configuration of an assembly-ready room 100 in the first embodiment will be described with reference to Figs. 1 to 10. Fig. 1 is a perspective view showing an example of an assembly-ready room according to the first embodiment of the present invention. Fig. 2 is a six-view diagram schematically showing the assembly-ready room of Fig. 1. In Figs. 2 to 6, (a) is a front view, (b) is a rear view, (c) is a right side view, (d) is a left side view, (e) is a plan view, and (f) is a bottom view. In each figure, some of the reference numerals are omitted as appropriate to avoid cluttering the drawings.

[0011] The prefabricated room 100 is constructed by assembling multiple panels (20, 30, 40, 70) each having a plate-like plate portion and a flange portion extending vertically from each of the four edges of the plate portion. The prefabricated room 100 has a peripheral wall 10, a top wall 50, and a bottom wall 60, and is a hollow box. The peripheral wall 10 has a door panel 20, four peripheral wall panels 30, and at least one peripheral wall extension panel 40. The door panel 20, the peripheral wall panel 30, and the peripheral wall extension panel 40 are all equal in height and thickness. The top wall 50 and the bottom wall 60 each have two lid panels 70 that are rectangular in plan view.

[0012] 1 and 2 is formed in the shape of a hollow rectangular parallelepiped, and the door panel 20, peripheral wall panel 30, and peripheral wall extension panel 40 are each rectangular in front or side view. In the prefabricated room 100 shown in Figures 1 and 2, the peripheral wall 10 has six peripheral wall extension panels 40, and the top wall 50 and bottom wall 60 each have two lid panels 70 that are rectangular in plan view.

[0013] The door panel 20 is provided with an opening 20h that serves as an entrance and exit, and a seal member S, such as a trim seal, is attached to the edge of the opening 20h. A frame 21 is attached to the front surface of the door panel 20 so as to surround the opening 20h. A door element 22 that enables the opening 15 to be opened and closed is attached to the back surface of the door panel 20 via a connecting member (not shown) such as a hinge. A handle 23 may be attached to the door element 22. The door element 22 is made of a material such as acrylic or polycarbonate and has transparency. However, the door element 22 may not have transparency, or may be partially made of a transparent material.

[0014] The prefabricated room 100 of the first embodiment is an oxygen chamber equipped with a function for increasing the air pressure inside the chamber (hereinafter also referred to as an internal pressure increasing function), and therefore has one or more pressurizing means (not shown) equipped with an air compressor that generates compressed air. The pressurizing means sends compressed air into the chamber to increase the air pressure inside the chamber. In other words, the prefabricated room 100 is configured to increase the internal air pressure above atmospheric pressure, thereby increasing the amount of oxygen dissolved in the blood of a subject entering the room.

[0015] The prefabricated room 100 also has an operation function unit 90 that is configured by combining components such as a relief valve, a pressure reducing valve, and an operation panel. While FIG. 1 shows an example in which the components of the operation function unit 90 are attached to one peripheral wall extension panel 40, the present invention is not limited to this, and the components of the operation function unit 90 may be arranged across multiple panels. Each component of the operation function unit 90 can be selected as appropriate. The prefabricated room 100 may have one or more oxygen concentrators. An oxygen concentrator absorbs nitrogen, which is a component of air, to produce air with a high oxygen concentration.

[0016] As described above, the height Td of the door panel 20, the height T3 of the peripheral wall panel 30, and the height T4 of the peripheral wall extension panel 40 are all equal (Td = T3 = T4). Furthermore, the thickness Sd of the door panel 20, the thickness S3 of the peripheral wall panel 30, and the thickness S4 of the peripheral wall extension panel 40 are all equal (Sd = S3 = S4). The width W3 of the peripheral wall panel 30 is longer than the width W4 of the peripheral wall extension panel 40 by the thickness Sd of the door panel 20 (W3 = W4 + Sd). This configuration allows the overall shape of the peripheral wall 10 to be maintained even if the position of the door panel 20 is changed by adjusting the positions of the peripheral wall panel 30 and the peripheral wall extension panel 40 (see FIGS. 7 to 10).

[0017] In the knockdown room 100 illustrated in Figures 1 and 2, the length T7 of the lid panel 70 is four times the width W4 plus twice the thickness Sd (T7 = W4 x 4 + Sd x 2). The width W7 of the lid panel 70 is equal to the width W3 of the peripheral wall panel 30. In the first embodiment, the thickness S7 of the lid panel 70 is equal to the thickness of each panel constituting the peripheral wall 10 (S7 = Sd), but these do not necessarily have to be equal.

[0018] Heights Td, T3, and T4 should be set to a height that allows a person to relax in the room, taking into account the average height of the person entering the room. The design should also take into account ease of entry and exit through opening 20h. The person entering the room is not limited to humans, but may also be an animal. Widths Wd, W3, W4, and W7 should be set so that each panel has a certain rigidity to ensure durability against increased internal pressure. The widths of each panel (Wd, W3, W4, and W7) should be as long as possible while maintaining a certain rigidity, from the perspectives of reducing the number of components, improving workability, and reducing costs. Thicknesses Sd, S3, S4, and S7 should be set so that each panel has a certain rigidity while also facilitating joining of the panels.

[0019] In the prefabricated room 100 of the first embodiment, the width Wd of the door panel 20 is a natural number multiple (positive integer multiple) of the width W4 of the peripheral extension panel 40 (Wd = W4 × N: N is any natural number). That is, the width Wd of the door panel 20 may be three, four, five, or more times the width W4. However, if the width W4 is made as long as possible with a view to reducing the number of components and labor, it is preferable that the width Wd be three times or less the width W4. However, the width Wd may be equal to the width W4 (Wd = W4) as long as it does not impede the entry and exit of persons attempting to enter the room.

[0020] In the prefabricated room 100 illustrated in each figure, the width Wd of the door panel 20 is twice the width W4 of the peripheral wall extension panel 40 (Wd = W4 × 2). Therefore, the door panel 20 is provided with an opening 20h large enough for entry and exit, and the overall shape of the peripheral wall 10 can be easily maintained even if the position of the door panel 20 is changed. The door panel 20 has a frame 21 that enhances its durability against increased internal pressure. Each panel constituting the prefabricated room 100 is preferably formed from a material such as metal with excellent mechanical strength, such as stainless steel, steel, or iron. The frame 21 may be formed from the same material as each panel, or from a different material.

[0021] 3 is a six-view diagram schematically illustrating the door panel 20. The door panel 20 is rectangular in front view and includes a plate-like plate portion 20p and flange portions (21m, 22m) standing vertically from each of the four edges of the plate portion 20p. The plate portion 20p is a plate-like member with an opening 20h on the inside. In the door panel 20, the two flange portions 21m along the longitudinal direction and the two flange portions 22m along the lateral direction each have a plurality of screw holes h.

[0022] FIG. 4 is a six-view diagram schematically illustrating the peripheral wall panel 30. The peripheral wall panel 30 is rectangular in front view and includes a plate-like plate portion 30p and flange portions (31m, 31n, 32m) extending vertically from each of the four edges of the plate portion 30p. The peripheral wall panel 30 includes a flange portion 31m arranged along the longitudinal direction and having multiple screw holes h, and a flat flange portion 31n without any screw holes h. The peripheral wall panel 30 also includes two flange portions 32m arranged along the lateral direction and having multiple screw holes h. The peripheral wall panel 30 also includes a connecting flange 34 extending vertically inward from the edge of one of the two flange portions arranged along the height direction, i.e., the flange portion 31n. The connecting flange 34 has multiple screw holes h. Note that the height direction refers to the height direction of the prefabricated room 100 when assembled and ready for use.

[0023] 5 is a six-view diagram schematically illustrating the peripheral wall extension panel 40. The peripheral wall extension panel 40 is rectangular in front view and includes a plate-like plate portion 40p and flange portions (41m, 42m) extending perpendicularly from each of the four edges of the plate portion 40p. In the peripheral wall extension panel 40, the two flange portions 41m along the longitudinal direction and the two flange portions 42m along the lateral direction each have a plurality of screw holes h. Although not shown, in the case of the prefabricated room 100 illustrated in FIGS. 1 and 2, the plate portion 40p of one peripheral wall extension panel 40 is provided with a plurality of holes for attaching the components that make up the operating function unit 90.

[0024] The flange portion 21m of the door panel 20, the flange portion 31m of the peripheral wall panel 30, the connecting flange 34, and the flange portion 41m of the peripheral wall extension panel 40 have a common arrangement of the multiple screw holes h. In the first embodiment, the multiple screw holes h of the flange portion 21m, the flange portion 31m, the connecting flange 34, and the flange portion 41m are arranged symmetrically in the vertical direction. Therefore, at least the peripheral wall panel 30 and the peripheral wall extension panel 40 can be used even when they are turned upside down. The door panel 20 may be configured so that it can be used when turned upside down.

[0025] FIG. 6 is a six-view diagram schematically illustrating the lid panel 70. The lid panel 70 is rectangular in front view and includes a plate-like plate portion 70p and flange portions (71m, 71n, 72n) extending vertically from each of the four edges of the plate portion 70p. The lid panel 70 includes a flange portion 71m arranged along the longitudinal direction and having a plurality of screw holes h, and a flat flange portion 71n without any screw holes h. The lid panel 70 also includes two flange portions 72n extending along the lateral direction. The lid panel 70 also includes a three-sided flange 74 extending vertically inward from the edge of the flange portion 71n along the longitudinal direction and the edges of the two flange portions 72n along the lateral direction. The three-sided flange 74 is concave-shaped in rear view. The three-sided flange 74 includes a plurality of screw holes h. More specifically, the three-way flange 74 has a plurality of screw holes h provided in two portions along the short side direction and a portion along the long side direction.

[0026] In the first embodiment, the flange portion 22m, the flange portion 32m, the flange portion 42m, and the three-way flange 74 each have at least one set of screw hole groups K. The screw hole groups K are formed by a plurality of screw holes h arranged symmetrically. In the example shown in each figure, the flange portion 22m has two sets of screw hole groups K, and the flange portions 32m and 42m each have one set of screw hole groups K. Furthermore, the three-way flange 74 has one set of screw hole groups K in each of its two portions along the short side direction, and four sets of screw hole groups K in its portion along the long side direction.

[0027] 4, one screw hole h is arranged at the end on the flange portion 31m side, and a screw hole group K is arranged adjacent to this. The arrangement of the multiple screw holes h in flange portion 32m is the same as the arrangement of the multiple screw holes h in the portion of three-way flange 74 that runs along the short side. In other words, one screw hole h is arranged in the three-way flange 74 at the end on the flange portion 71n side of the portion that runs along the short side. The abutting flanges of each panel are joined together with bolts, nuts, etc. (The flange in this expression includes the flange portion of each panel, the connecting flange 34, and the three-way flange 74).

[0028] In the case of an oxygen chamber intended for human entry, the prefabricated room 100 may have, for example, heights Td, T3, and T4 of 1420 mm, thicknesses Sd, S3, and S4 of 60 mm, widths Wd of 960 mm, widths W3 of 540 mm, and widths W4 of 480 mm. In this case, length T7 is 2040 mm, and width W7 is 540 mm. If the thickness S7 of the cover panel 70 is 60 mm, the overall dimensions of the prefabricated room 100 are 1540 mm in height, 2040 mm in width, and 1080 mm in depth. However, these dimensions can be changed as needed. The prefabricated room 100 of the first embodiment is designed so that each panel is joined to the adjacent panels with bolts and nuts (not shown) through screw holes in the panels.

[0029] 7 to 10 are explanatory diagrams illustrating some of the arrangement patterns of the door panel 20. In Fig. 7 to 10, the lines of the blocks are thicker in the order of the peripheral wall extension panel 40, the peripheral wall panel 30, and the door panel 20, so that the changes in the arrangement of the door panel 20, the peripheral wall panel 30, and the peripheral wall extension panel 40 can be easily seen.

[0030] The peripheral wall 10 illustrated in Figures 7 to 10 has a cylindrical shape that is rectangular in plan view. In Figures 7 to 9, the door panel 20 is disposed in the longitudinal direction in plan view, and in Figure 10, the door panel 20 is disposed in the lateral direction in plan view. The door panel 20 is disposed on the left side of the front along the longitudinal direction in Figure 7, in the center of the front along the longitudinal direction in Figure 8, and on the right side of the front along the longitudinal direction in Figure 9, and similarly, the door panel 20 can be disposed in three positions on the rear side. The door panel 20 is disposed on the right side of the lateral direction in Figure 10, and can also be disposed on the left side in the same manner.

[0031] 7 to 9 show an example in which the peripheral wall panel 30 is arranged on the short side of the peripheral wall 10, but the peripheral wall panel 30 may also be arranged on the long side of the peripheral wall 10. That is, by turning the peripheral wall panel 30 upside down, it can be arranged in a manner that interchanges with the adjacent peripheral wall extension panel 40 in the long side (except for the lower left of FIG. 7 and the lower right of FIG. 9). Also, while FIG. 10 shows an example in which the two peripheral wall panels 30 are arranged uniformly on the left and right, the left peripheral wall panel 30 may be arranged on the short side of the peripheral wall 10 in an interchangeable manner with the adjacent peripheral wall extension panel 40.

[0032] In the prefabricated room 100, the position of the door panel 20 can be changed 360 degrees by adjusting the positions of the peripheral wall panels 30 and the peripheral wall extension panels 40. Even if the position of the door panel 20 is changed, the position of the multiple screw holes h at the upper end of the peripheral wall 10 of the prefabricated room 100 does not change, as illustrated in FIGS. 7 to 10 . That is, the upper end of the peripheral wall 10 is composed of the flange portions 22m and 42m, each having only the screw hole group K, and the flange portion 32m, which has the screw hole group K as well as the screw hole h at the end on the flange portion 31m side. Therefore, even if the position of the door panel 20 is changed, the overall position of the screw holes h does not change. Therefore, the prefabricated room 100 can use a common lid panel 70 regardless of the position of the door panel 20, and the overall shape can be maintained.

[0033] That is, with an assembly kit for a prefabricated room 100 made up of multiple panels, even if the location of the entrance / exit needs to be changed due to user needs or the installation environment, the same assembly kit can be used to construct a prefabricated room 100 with a different entrance / exit. This eliminates the need for re-arranging and transporting, and reduces the number of assembly kits for the prefabricated room 100 in stock. The assembly kit may also include bolts and nuts for assembling the multiple panels.

[0034] As described above, the assembly kit for the prefabricated room 100 of the first embodiment includes multiple panels each having a plate-like plate portion and a flange portion extending vertically from each of the four edges of the plate portion. The assembly kit includes the door panel 20, four peripheral wall panels 30, and at least one peripheral wall extension panel 40 as components constituting the peripheral wall 10. The door panel 20, the peripheral wall panel 30, and the peripheral wall extension panel 40 are all equal in height and thickness. The width W3 of the peripheral wall panel 30 is longer than the width W4 of the peripheral wall extension panel 40 by the thickness Sd of the door panel 20. The width Wd of the door panel 20 is a natural number multiple of the width W4 of the peripheral wall extension panel 40. The peripheral wall panel 30 has a connecting flange 34 extending vertically inward from the edge of one of two flange portions arranged along the height direction. Therefore, the arrangement of the entrances and exits of the prefabricated room 100 can be freely changed by combining panels with a simple structure. Incidentally, when the width Wd of the door panel 20 is an odd multiple of the width W4, such as 1 or 3 times, the number of peripheral wall extension panels 40 will be odd. When the width Wd of the door panel 20 is an even multiple of the width W4, the number of peripheral wall extension panels 40 will be even.

[0035] Each of the four flange portions (21m, 22m, 41m, 42m) of the door panel 20 and the peripheral wall extension panel 40 illustrated in each figure has a plurality of screw holes h. Also, the peripheral wall panel 30 has a plurality of screw holes h in the connection flange 34 and in three flange portions (31m, 32m) other than the flange portion from which the connection flange 34 extends. Therefore, the knockdown room 100 can be easily assembled using bolts and nuts.

[0036] In the first embodiment, the top wall 50 and the bottom wall 60 each have two lid panels 70 that are rectangular in plan view. The lid panel 70 has a three-sided flange 74 that extends perpendicularly inward from the edge of one (71n) of the two flange portions along the longitudinal direction and the edge of the two flange portions (72n) along the lateral direction. The width W7 of the lid panel 70 is equal to the width W3 of the peripheral wall panel 30. With this configuration, the lid panel 70 can be arranged in correspondence with the peripheral wall panel 30, and the top wall 50 and the bottom wall 60 can have higher pressure resistance than when they are configured from a single lid panel.

[0037] The cover panel 70 may have a plurality of screw holes h formed in the three-sided flange 74, and a plurality of screw holes h formed in a flange portion (71m) other than the three flange portions to which the three-sided flange 74 extends. The cover panel 70 having such a configuration can be easily attached to the peripheral wall 10 with bolts and nuts by aligning the plurality of screw holes h with the plurality of screw holes h at the upper or lower end of the peripheral wall 10. The top wall 50 and the bottom wall 60 may be formed from cover panels 70 of the same material, structure, and number, but the prefabricated room 100 may use different materials, structures, and numbers of panels for the top wall 50 and the bottom wall 60.

[0038] Embodiment 2 An example of the configuration of an assembly-type room 200 in the second embodiment will be described with reference to FIGS. 11 to 30. FIG. 11 is a perspective view showing an example of an assembly-type room according to the second embodiment of the present invention. FIG. 12 is a six-view diagram schematically showing the assembly-type room of FIG. 11. In FIGS. 12 to 17, (a) is a front view, (b) is a rear view, (c) is a right side view, (d) is a left side view, (e) is a plan view, and (f) is a bottom view. Regarding the assembly-type room 200 and its assembly kit, the description of the same components as those in the first embodiment will be omitted or simplified. Regarding the assembly-type room 200, components equivalent to those of the assembly-type room 100 will be assigned the same reference numerals, and the description will be omitted or simplified. In each figure, some of the reference numerals will be omitted as appropriate to avoid cluttering the drawings, etc.

[0039] The prefabricated room 200 is constructed by assembling a plurality of panels (120, 130, 140, 170, 80) each having a plate-like portion and a flange portion erected vertically from each of the four edges of the plate portion. The prefabricated room 200 has a peripheral wall 110, a top wall 150, and a bottom wall 160, and is shaped like a hollow box.

[0040] The peripheral wall 110 has a door panel 120, four peripheral wall panels 130, and at least one peripheral wall extension panel 140. The door panel 120, the peripheral wall panels 130, and the peripheral wall extension panel 140 have the same height and thickness. The top wall 150 and the bottom wall 160 each have two lid panels 70 that are rectangular in plan view, and at least one lid extension panel 80 that is rectangular in plan view. The lid panel 170 and the lid extension panel 80 have the same length and thickness.

[0041] 11 and 12 is formed in the shape of a hollow rectangular parallelepiped, and the door panel 120, peripheral wall panel 130, and peripheral wall extension panel 140 are each rectangular in front or side view. In the knockdown room 200 shown in Figures 11 and 12, the peripheral wall 110 has 14 peripheral wall extension panels 140, and the top wall 50 and bottom wall 60 each have two lid panels 70 that are rectangular in plan view and four lid extension panels 80 that are rectangular in plan view.

[0042] The door panel 120 is provided with an opening 20h that serves as an entrance and exit, and a seal member S is attached to the edge of the opening 20h. The door panel 120 also has a group of holes 20g made up of a plurality of holes for attaching the components that make up the operation function unit 90 (see FIG. 13). A frame portion 121 is attached to the surface of the door panel 120 so as to surround the group of holes 20g and the opening 20h. The prefabricated room 200 of the second embodiment is an oxygen chamber equipped with an internal pressure increasing function, and therefore has one or more pressurizing means.

[0043] The width W3 of the peripheral wall panel 130 is longer than the width W4 of the peripheral wall extension panel 140 by the thickness Sd of the door panel 120 (W3 = W4 + Sd). In the knockdown room 200 illustrated in Figures 11 and 12, the length T7 of the lid panel 170 and the length T8 of the lid extension panel 80 are equal to the sum of twice the width W3 and twice the width W4 (T7 = T8 = W3 × 2 + W4 × 2). In other words, the length T7 of the lid panel 170 and the length T8 of the lid extension panel 80 are equal to four times the width W3 plus twice the thickness Sd (T7 = T8 = W3 × 4 + Sd × 2).

[0044] The width W7 of the lid panel 170 is equal to the width W3 of the peripheral wall panel 130. The width W8 of the lid extension panel 80 is equal to the width W4 of the peripheral wall extension panel 140. The heights Td, T3, and T4 should be set taking into consideration the general height of the person entering the room, ease of entry and exit through the opening 20h, and ensuring space for the operation function unit 90. The widths Wd, W3, W4, W7, and W8 should be set so that each panel has a certain rigidity to ensure durability against increased internal pressure. The widths of each panel (Wd, W3, W4, W7, and W8) should be as long as possible while still ensuring a certain rigidity, from the perspectives of reducing the number of parts, improving workability, and reducing costs. The thicknesses Sd, S3, S4, S7, and S8 may be set so as to provide a certain level of rigidity to each panel and to facilitate joining of the panels together.

[0045] In the knockdown room 200 illustrated in each figure, the width Wd of the door panel 120 is twice the width W4 of the peripheral wall extension panel 140 (Wd = W4 × 2), but this is not limited to this. The knockdown room 200 may be configured so that the width Wd of the door panel 120 is a natural number multiple of the width W4 of the peripheral wall extension panel 140. However, if the width W4 is to be made as long as possible with a view to reducing the number of components, the width Wd is preferably three times or less the width W4.

[0046] The door panel 120 has an increased durability against an increase in internal pressure due to the frame portion 121. The frame portion 121 is configured by integrally connecting an outer frame portion 20a and a reinforcing portion 20b. The outer frame portion 20a is a frame-shaped member that surrounds the hole group 20g and the opening 20h. The reinforcing portion 20b is a rod-shaped member that is adjacent to the upper edge of the opening 20h and serves as a partition between the operating function portion 90 and the opening 20h. The frame portion 121 increases the pressure resistance of the door panel 120 due to the reinforcing portion 20b, and also enhances the design with its figure-8-shaped appearance when viewed from the front.

[0047] FIG. 13 is a six-view diagram schematically showing the door panel 120. The basic configuration of the door panel 120 is similar to that of the door panel 20. The door panel 120 has a group of holes 20g and has a length Td longer than that of the door panel 20. FIG. 14 is a six-view diagram schematically showing the peripheral wall panel 130. The basic configuration of the peripheral wall panel 130 is similar to that of the peripheral wall panel 30. FIG. 15 is a six-view diagram schematically showing the peripheral wall extension panel 140. The basic configuration of the peripheral wall extension panel 140 is similar to that of the peripheral wall extension panel 40. FIG. 16 is a six-view diagram schematically showing the lid panel 170. The basic configuration of the lid panel 170 is similar to that of the lid panel 70.

[0048] 17 is a six-view diagram schematically illustrating the lid extension panel 80. The lid extension panel 80 is rectangular in front view and has a plate-like plate portion 80p and flange portions (81m, 82n) standing vertically from each of the four edges of the plate portion 80p. The lid extension panel 80 has a flange portion 81m with multiple screw holes h along the longitudinal direction and a flat flange portion 82n with no screw holes h along the lateral direction.

[0049] The lid extension panel 80 has lid flanges 84 extending vertically inward from the edges of each of the two flange portions (82n) along the short side direction. The lid flanges 84 have a plurality of screw holes h. More specifically, the lid flange 84 has at least one set of screw hole group K. The lid flange 84 illustrated in each figure has one set of screw hole group K. The flange portion 71m of the lid panel 170 and the flange portion 81m of the lid extension panel 80 have the same arrangement of the multiple screw holes h. Therefore, the lid panel 170 and the lid extension panel 80 can be joined with their surfaces flush. The abutting flanges of each panel are joined with bolts, nuts, etc. (The flange in this expression includes the flange portions of each panel, the connecting flange 34, the three-way flange 74, and the lid flange 84).

[0050] In the case of an oxygen chamber intended for human entry, the prefabricated room 200 may have, for example, heights Td, T3, and T4 of 1920 mm, thicknesses Sd, S3, and S4 of 60 mm, widths Wd of 960 mm, widths W3 of 540 mm, and widths W4 of 480 mm. In this case, lengths T7 and T8 are 2040 mm, widths W7 of 540 mm, and widths W8 of 480 mm. If the thickness S7 of the cover panel 170 is 60 mm, the overall dimensions of the prefabricated room 200 are 2040 mm in height, 3000 mm in width, and 2040 mm in depth. However, these dimensions can be changed as needed. The prefabricated room 200 of the second embodiment is designed so that each panel is joined to the adjacent panels with bolts and nuts (not shown) through screw holes in the panels.

[0051] 18 to 27 are explanatory diagrams illustrating some of the arrangement patterns of the door panel 120. In Fig. 18 to 27, the lines of the blocks are made thicker in the order of the peripheral wall extension panel 140, the peripheral wall panel 130, and the door panel 120, so that the changes in the arrangement of the door panel 120, the peripheral wall panel 130, and the peripheral wall extension panel 140 can be easily seen.

[0052] The peripheral wall 110 illustrated in Figures 18 to 27 has a cylindrical shape that is rectangular in plan view. In Figures 18 to 22, the door panel 120 is disposed in the longitudinal direction in plan view, and in Figures 23 to 27, the door panel 120 is disposed in the lateral direction in plan view. The position of the door panel 120 moves to the right in the order of Figures 18 to 22, and moves upward in the order of Figures 23 to 27. The position of the door panel 120 on the back side can be changed in the same way as in Figures 18 to 22, and the position can also be changed on the left side in the same way as in Figures 23 to 27.

[0053] 18 to 22 show an example in which the peripheral wall panel 130 is disposed on the short side of the peripheral wall 110, but the peripheral wall panel 130 may also be disposed on the long side of the peripheral wall 110. That is, the peripheral wall panel 130 can be swapped with the adjacent peripheral wall extension panel 140 in the long direction by flipping it upside down (except for the bottom left of FIG. 18 and the bottom right of FIG. 22). The same applies to the peripheral walls 110 illustrated in FIGS. 23 to 27. For example, the peripheral wall panel 130 in the upper right of FIG. 23 may be swapped with the adjacent peripheral wall extension panel 140 in the long direction, as shown in FIG. 24. Furthermore, the peripheral wall panel 130 on the right side of FIG. 25 may be swapped with the adjacent peripheral wall extension panel 140 in the long direction, as shown in FIG. 26. The same applies to the other corners of the peripheral wall 110.

[0054] In the prefabricated room 200, the position of the door panel 120 can be changed 360 degrees by adjusting the positions of the peripheral wall panel 130 and the peripheral wall extension panel 140. Even if the position of the door panel 120 is changed, the position of the multiple screw holes h at the upper end of the peripheral wall 110 does not change, as illustrated in FIGS. 18 to 27 . That is, the upper end of the peripheral wall 110 is composed of the flange portion 22m and the flange portion 42m, which have only the screw hole group K, and the flange portion 32m, which has the screw hole group K as well as the screw hole h at the end on the flange portion 31m side. Therefore, even if the position of the door panel 120 is changed, the overall position of the screw holes h does not change. Therefore, the prefabricated room 200 can use the same lid panel 70 and lid extension panel 80 regardless of the position of the door panel 120, and the overall shape can be maintained.

[0055] That is, with an assembly kit for the prefabricated room 200 made up of multiple panels, even if the location of the entrance / exit needs to be changed due to the user's needs or the installation environment, the prefabricated room 200 can be constructed using the same assembly kit. This eliminates the need for re-arranging and transporting, and reduces the number of assembly kits for the prefabricated room 200 in stock. The assembly kit may also include bolts and nuts for assembling the multiple panels.

[0056] Furthermore, as shown in FIGS. 28 and 29 , the width of the prefabricated room 200 of the second embodiment can be easily increased or decreased by increasing or decreasing the number of lid extension panels 80 and the number of peripheral wall extension panels 140. In the example of FIG. 29 , when four peripheral wall extension panels 140 are arranged behind the peripheral wall 110, the peripheral wall 110 has a square shape in a plan view. The peripheral wall 110 illustrated in FIG. 29 may also have two peripheral wall extension panels 140 arranged behind the peripheral wall 110. To increase or decrease the depth of the prefabricated room 200, the number of peripheral wall extension panels 140 in the depth direction can be increased or decreased, as shown in FIG. 30 . When such a configuration is adopted, the length T7 of the lid panel 170 and the length T8 of the lid extension panel 80 can be increased or decreased. 29 and 30, similarly to the examples of FIGS. 18 to 27, the position of the door panel 120 can be changed without changing the arrangement of the screw holes h on the entire peripheral wall 110.

[0057] When the number of peripheral wall extension panels 140 in the depth direction is increased, at least one of the lid panel 170 and the lid extension panel 80 may be composed of multiple panels. For example, when the lid panel 170 is composed of two adjustment panels, each adjustment panel may be configured to have an L-shaped flange extending vertically inward from the edge of one of the two flange portions along the longitudinal direction and the edge of one of the two flange portions along the lateral direction. Each adjustment panel may have multiple screw holes h in the other of the two flange portions along the longitudinal direction, the other of the two flange portions along the lateral direction, and the L-shaped flange. The two adjustment panels are symmetrical to each other. When the lid extension panel 80 is composed of two extension panels, each extension panel may be configured to have a lid flange 84 extending vertically inward from the edge of one of the two flange portions along the lateral direction. Each extension panel may have a plurality of screw holes h provided in the two flange portions along the longitudinal direction, the other of the two flange portions along the lateral direction, and the lid flange 84, respectively.

[0058] As described above, the assembly kit for the prefabricated room 200 of the second embodiment includes multiple panels each having a plate-like plate portion and a flange portion extending vertically from each of the four edges of the plate portion. The assembly kit includes the door panel 120, four peripheral wall panels 130, and at least one peripheral wall extension panel 140 as components constituting the peripheral wall 110. The door panel 120, the peripheral wall panels 130, and the peripheral wall extension panel 140 are all equal in height and thickness. The width W3 of the peripheral wall panel 130 is longer than the width W4 of the peripheral wall extension panel 140 by the thickness Sd of the door panel 120. The width Wd of the door panel 120 is a natural number multiple of the width W4 of the peripheral wall extension panel 140. The peripheral wall panel 130 has a connecting flange 34 extending vertically inward from the edge of one of two flange portions arranged along the height direction. Therefore, the arrangement of the entrance and exit of the prefabricated room 100 can be freely changed by combining panels with a simple structure.

[0059] The top wall 150 and the bottom wall 160 each have at least one lid extension panel 80 that is rectangular in plan view. The lid extension panel 80 has lid flanges 84 that extend perpendicularly inward from the edges of two flange portions along the short side. The lid extension panel 80 can be attached to the peripheral wall 110 with the two lid flanges 84 abutting against the upper ends of opposing panels of the peripheral wall 110.

[0060] In the assembly kit for the prefabricated room 200 according to the second embodiment, the width W7 of the lid panel 70 is equal to the width W3 of the peripheral wall panel 130, and the width W8 of the lid extension panel 80 is equal to the width W4 of the peripheral wall extension panel 140. Here, one lid extension panel 80 and two peripheral wall extension panels 140 are referred to as an extension unit. The width of the prefabricated room 200 can be easily increased or decreased by adding or removing the extension unit. The lid flange 84 of the lid extension panel 80 may be provided with multiple screw holes corresponding to some of the multiple screw holes h at the upper or lower end of the peripheral wall 110. This allows the lid extension panel 80 to be easily attached to the peripheral wall 110 using bolts and nuts. The top wall 150 and the bottom wall 160 may be constructed of the same material, structure, and number of lid panels 170 and lid extension panels 80, but the prefabricated room 200 may use different materials, structures, and numbers of panels for the top wall 150 and the bottom wall 160. Other configurations and effects are the same as those of the prefabricated room 100 and its assembly kit of the first embodiment.

[0061] The above-described embodiments are merely examples of a knockdown room and its assembly kit, and the technical scope of the present invention is not limited to these embodiments. For example, in the first embodiment, the top wall 50 and the bottom wall 60 are formed of two lid panels 70, but this is not limiting. For example, at least one of the top wall 50 and the bottom wall 60 may be formed of a single panel shaped like two lid panels 70 joined together. The panel has four flanges extending vertically inward from the edges of the flange portions on all four sides. The four flanges may be configured with multiple screw holes h. The top wall 50 and the bottom wall 60 may also be formed of three or more panels that, when combined, are the same size as the two lid panels 70. Similarly, at least one of the top wall 150 and the bottom wall 160 in the second embodiment may be formed of a single panel. In each panel constituting the prefabricated rooms 100 and 200, the number of screw holes h included in the screw hole group K is not limited to the example in each figure, and may be changed as appropriate depending on the size of each panel of the prefabricated rooms 100 and 200 and the required level of airtightness. Although each figure illustrates a screw hole group K composed of an even number of screw holes h, the screw hole group K may also be composed of an odd number of screw holes h.

[0062] The number and size of each panel constituting the prefabricated rooms 100 and 200 are not limited to the above examples and may be changed as appropriate. For example, the above drawings show an example in which the peripheral wall 10 has an even number of peripheral wall extension panels 40 and the peripheral wall 110 has an even number of peripheral wall extension panels 140, but this is not limiting. The prefabricated room 100 may be configured so that the peripheral wall 10 has an odd number of peripheral wall extension panels 40, and the prefabricated room 200 may be configured so that the peripheral wall 110 has an odd number of peripheral wall extension panels 140.

[0063] The prefabricated room 100 or 200 may be configured to have only one peripheral wall extension panel 40 or 140, as shown in Figure 31. In this case, the width Wd of the door panel 20 or 120 should be equal to the width W4 of the peripheral wall extension panel 40 or 140. Even with this configuration, the prefabricated rooms 100 and 200 can have the door panel 20 or 120 arranged in either the short or long direction, as shown in Figures 31(a) to (c).

[0064] Although the respective figures mainly illustrate prefabricated rooms 100 and 200 that are rectangular in plan view, the prefabricated rooms 100 and 200 may be square in plan view. The peripheral walls 110 in Figures 29 and 30 may also be square in plan view. For example, the prefabricated rooms 100 or 200 may be configured to have three peripheral wall extension panels 40 or 140, as shown in Figure 32. The door panel (20, 120) in Figure 32(a) may be located on the right side of the front, and the door panel (20, 120) in Figure 32(b) may be located on the right side of the back.

[0065] In a prefabricated room that is square in plan view, if the location of an entrance / exit needs to be changed, the entire room can be rotated from its intended location before workers begin assembling it, so that the entrance / exit is in the desired position. However, if the panel location needs to be changed during or after assembly, conventional prefabricated rooms must be disassembled and reassembled. In this regard, with prefabricated rooms 100 and 200, even if the location of an entrance / exit needs to be changed during assembly, the location can be easily changed by simply changing the location of some panels. The prefabricated rooms 100 and 200 may be hollow rectangular parallelepiped or hollow cubic.

[0066] The prefabricated loom 100 may be assembled using other fastening members instead of bolts and nuts. For example, the prefabricated loom 100 may be assembled using rivets. In this case, each panel may have holes for inserting rivets instead of the multiple screw holes h. Furthermore, the prefabricated loom 100 may be assembled using clamps that clamp and secure the flanges of each panel together. Alternatively, the prefabricated loom 100 may be joined to each other by magnetic force. In this case, magnets may be embedded in the flanges of each panel, or two adjacent flanges may be clamped and secured by one or more pairs of magnets. However, the prefabricated loom 100 may also be joined to each other by welding. When using clamps, magnets, or welding, each panel does not need to have multiple holes, such as the multiple screw holes h. However, the prefabricated loom 100 may be configured using a combination of the above specifications.

[0067] The panels that make up the prefabricated rooms 100 and 200 are not limited to the above examples and can be made from a variety of materials. The prefabricated rooms 100 and 200 may use aluminum, titanium, carbon, or the like as the main material for each panel. The shape and size of the reinforcing members in each panel may be changed as appropriate depending on factors such as the expected amount of internal pressure increase. The reinforcing members illustrated in the rear views (b) of Figures 4 to 6 and 14 to 17 are rim-shaped members that extend vertically inward from the flanges of each panel.

[0068] Since it is anticipated that one or both of the pressurizing means and the operating function unit 90 may be sold separately from each panel, the prefabricated rooms 100, 200 and their assembly kits may not have at least one of the pressurizing means and the operating function unit 90. In the above description, the prefabricated rooms 100 and 200 are exemplified as oxygen chambers equipped with an internal pressure increase function, but the prefabricated rooms 100 and 200 are not limited to this, and may also be sheds, storage sheds, warehouses, shelters, or the like that do not have an internal pressure increase function. While the embodiments have primarily described prefabricated rooms intended for people to enter, the prefabricated rooms 100, 200 and their assembly kits may also be sized for use by various animals.
