[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 transported.

[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.

[0006] One aspect of the present invention provides an assembly-type room having peripheral walls, a top wall, and a bottom wall, which are constructed by combining a plurality of 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 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 aspect 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.

[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.

[0010] Embodiment 1. An example of the configuration of an assembly-ready room 100 in this embodiment 1 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 embodiment 1 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 have been omitted as appropriate to avoid cluttering the drawings, etc.

[0011] The prefabricated room 100 is constructed by assembling multiple panels (20, 30, 40, 70) each having a plate-like 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, the peripheral wall panel 30, and the peripheral wall extension panel 40 are each rectangular in a front or side view. In the prefabricated room 100 illustrated in Figures 1 and 2, the peripheral wall 10 has six peripheral wall extension panels 40, and the top wall 50 and the bottom wall 60 each have two lid panels 70 that are rectangular in a plan view.

[0013] The door panel 20 has 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. The door element 22 may have a handle 23 attached to it. 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 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 a single peripheral wall extension panel 40, this is not limiting, and the components of the operation function unit 90 may be arranged across multiple panels. However, the components of the operation function unit 90 can be selected as appropriate. The prefabricated room 100 may also have one or more oxygen concentrators. An oxygen concentrator absorbs nitrogen from air to generate air with a high oxygen concentration.

[0016] As described above, the height Td of the door panel 20 and the height T ３ and the height T of the peripheral wall extension panel 40 ４ is equal to (Td = T ３ =T ４ ). The thickness Sd of the door panel 20 and the thickness S of the peripheral wall panel 30 ３ and the thickness S of the peripheral wall extension panel 40 ４ is equal to (Sd = S ３ = S ４ ). The width W of the peripheral wall panel 30 ３ is the width W of the peripheral wall extension panel 40 ４ The door panel 20 is longer than the thickness Sd of the door panel 20 (W ３ =W ４ +Sd) With this configuration, by adjusting the positions of the peripheral wall panel 30 and the peripheral wall extension panel 40, the overall shape of the peripheral wall 10 can be maintained even if the position of the door panel 20 is changed (see Figures 7 to 10).

[0017] In the prefabricated room 100 illustrated in FIGS. 1 and 2, the length T ７ is the width W ４ The length is four times the thickness Sd plus two times the thickness Sd (T ７ =W ４ × 4 + Sd × 2). The width W of the lid panel 70 ７ is the width W of the peripheral wall panel 30 ３ In the first embodiment, the thickness S of the cover panel 70 is equal to ７ The example in which the thickness of each panel constituting the peripheral wall 10 is equal to the thickness of the panel (S ７ =Sd), which do not necessarily have to be equal.

[0018] Height Td, Height T ３ , and height T ４ The width Wd and width Wh should be set to a height that allows the person entering the room to relax in the room, taking into consideration the general height of the person entering the room. At that time, it is also advisable to design with the ease of entry and exit through the opening 20h in mind. The person entering the room is not limited to a person, but may also be an animal. ３ , width W ４ , and width W ７ In order to ensure durability against an increase in internal pressure, it is advisable to set each panel to have a certain rigidity. ３ , W ４ , W ７ ) should be as long as possible within a range that ensures a certain level of rigidity, from the viewpoints of reducing the number of components, improving workability, and reducing costs. ３ , thickness S ４ , and thickness S ７ It is preferable to set the thickness so that each panel has a certain rigidity while making it easy to join the panels together.

[0019] In the prefabricated room 100 of the first embodiment, the width Wd of the door panel 20 is equal to the width W of the peripheral wall extension panel 40. ４ (Wd = W ４ ×N: N is an arbitrary natural number). That is, the width Wd of the door panel 20 is ４However, the width W may be set to three, four, or five times or more, taking into consideration the reduction in the number of components and the number of steps. ４ When making it as long as possible, the width Wd is ４ However, if it does not hinder the entrance and exit of the object to enter the room, the width Wd should be less than the width W ４ (Wd=W ４ ).

[0020] In the prefabricated room 100 illustrated in each figure, the width Wd of the door panel 20 is equal to the width W of the peripheral wall extension panel 40. ４ It is twice as long as Wd (W ４ x2). Therefore, even if the position of the door panel 20 is changed, the overall shape of the peripheral wall 10 can be easily maintained while providing the door panel 20 with an opening 20h wide enough for the entry and exit of an object. The door panel 20 has enhanced durability against an increase in internal pressure due to the frame 21. Each panel constituting the prefabricated room 100 is preferably formed from a material such as metal that has 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 portion 20p and flange portions (21m, 22m) extending perpendicularly from each of the four edges of the plate portion 20p. The plate portion 20p is a plate-like member with an opening 20h at 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 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 has 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 to be usable when turned upside down.

[0025] FIG. 6 is a six-view diagram schematically illustrating the cover panel 70. The cover 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 cover panel 70 includes a flange portion 71m arranged along the longitudinal direction and having multiple screw holes h, and a flat flange portion 71n without any screw holes h. The cover panel 70 also includes two flange portions 72n along the lateral direction. The cover panel 70 also includes a three-sided flange 74 extending vertically inward from the edges 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 multiple screw holes h. More specifically, the three-way flange 74 has a plurality of screw holes h formed in two portions along the short side direction and one 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-sided 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. The three-sided flange 74 has one set of screw hole groups K in each of two portions along the short side direction, and four sets of screw hole groups K in the portion along the long side direction.

[0027] 4 has one screw hole h arranged at the end on the flange portion 31m side, and a screw hole group K arranged adjacent to it. The arrangement of the multiple screw holes h in the flange portion 32m is the same as the arrangement of the multiple screw holes h in the portion of the three-sided flange 74 that extends along the short side. In other words, the three-sided flange 74 has one screw hole h arranged at the end on the flange portion 71n side of the portion that extends 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 connection flange 34, and the three-sided flange 74).

[0028] In the case of an oxygen room intended for people to enter, the prefabricated room 100 has a height Td, a height T ３ , and height T ４ is 1420 mm, thickness Sd, thickness S ３ , and thickness S ４ is 60 mm, width Wd is 960 mm, width W ３ is 540 mm, width W ４ In this case, the length T ７ is 2040 mm, and the width W ７ The thickness S of the cover panel 70 is 540 mm. ７ If the distance between the panels is 60 mm, the overall size of the prefabricated room 100 will be 1540 mm in height, 2040 mm in width, and 1080 mm in depth. However, these dimensions can be changed as appropriate. The prefabricated room 100 of the first embodiment is designed so that each panel is joined to the adjacent panels by bolts and nuts (not shown) through the 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, while 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. Similarly, the door panel 20 can be disposed in three positions on the rear side. In Figure 10, the door panel 20 is disposed on the right side of the lateral direction, but it 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 disposed on the short side of the peripheral wall 10, but the peripheral wall panel 30 may also be disposed on the long side of the peripheral wall 10. That is, by inverting 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 direction (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 uniformly disposed 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 loom 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. Furthermore, 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 does not change, as illustrated in FIGS. 7 to 10 . That is, because 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, the overall position of the screw holes h does not change even if the position of the door panel 20 is changed. Therefore, the prefabricated loom 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 knockdown room 100 of the first embodiment includes a plurality of 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 that make up 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 W of the peripheral wall panel 30 is ３ is the width W of the peripheral wall extension panel 40 ４ The width Wd of the door panel 20 is longer than the width W of the peripheral wall extension panel 40 by the thickness Sd of the door panel 20. ４ The peripheral wall panel 30 has a connecting flange 34 that extends vertically inward from the edge of one of two flanges arranged along the height direction. Therefore, by combining panels with a simple structure, the location of the entrance and exit of the prefabricated room 100 can be freely changed. Incidentally, when the width Wd of the door panel 20 is equal to the width W ４ When the width Wd of the door panel 20 is an odd multiple such as 1 or 3 times the width W ４ When the number of peripheral wall extension panels 40 is an even multiple of , the number of peripheral wall extension panels 40 is an even number.

[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 present 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 of the two flange portions (71n) along the longitudinal direction and the edge of the two flange portions (72n) along the lateral direction. The width W of the lid panel 70 is７ is the width W of the peripheral wall panel 30 ３ With this configuration, the cover 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 with a single cover 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 have panels of different material, structure, and number used for the top wall 50 and the bottom wall 60.

[0038] Embodiment 2. An example configuration of an assembly-type room 200 according to Embodiment 2 of the present invention 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 Embodiment 2 of the present invention.

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. Components of the assembly-type room 200 that are equivalent to those of the assembly-type room 100 are designated by the same reference numerals, and descriptions thereof are omitted or simplified. In each figure, some of the reference numerals are 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 extending 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 170 that are rectangular in plan view and at least one lid extension panel 80 that is rectangular in plan view. The lid panels 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, the peripheral wall panel 130, and the peripheral wall extension panel 140 are each rectangular in front or side view. In the prefabricated room 200 illustrated in Figures 11 and 12, the peripheral wall 110 has fourteen peripheral wall extension panels 140, and the top wall 150 and the bottom wall 160 each have two lid panels 170 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 consisting of a plurality of holes for attaching the components that make up the operation function unit 90 (see FIG. 13). A frame 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] Width W of peripheral wall panel 130 ３ is the width W of the peripheral wall extension panel 140 ４ The door panel 120 is longer than the thickness Sd of the door panel 120 (W ３ =W ４ In the prefabricated room 200 illustrated in FIGS. 11 and 12, the length T ７ and the length T of the lid extension panel 80 ８ is the width W ３ Twice the width W ４is equal to the sum of two times (T ７ =T ８ =W ３ ×2+W ４ × 2). In other words, the length T of the lid panel 170 ７ and the length T of the lid extension panel 80 ８ is the width W ３ The length is four times the thickness Sd plus two times the thickness Sd (T ７ =T ８ =W ３ x 4 + Sd x 2).

[0044] Width W of the lid panel 170 ７ is the width W of the peripheral wall panel 130 ３ The width W of the lid extension panel 80 is equal to ８ is the width W of the peripheral wall extension panel 140 ４ The height Td and the height T ３ , and height T ４ The widths Wd and W can be set in consideration of 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. ３ , width W ４ , width W ７ , and width W ８ In order to ensure durability against an increase in internal pressure, it is advisable to set each panel to have a certain rigidity. ３ , W ４ , W ７ , W ８ ) should be as long as possible within a range that ensures a certain level of rigidity, from the viewpoints of reducing the number of components, improving workability, and reducing costs. ３ , thickness S ４ , thickness S ７ , and thickness S ８ It is preferable to set the thickness so that each panel has a certain rigidity while making it easy to join the panels together.

[0045] In the knockdown room 200 illustrated in each figure, the width Wd of the door panel 120 is equal to the width W of the peripheral wall extension panel 140. ４ It is twice as long as (Wd = W ４The door panel 120 has a width Wd that is equal to or larger than the width W of the peripheral wall extension panel 140. ４ However, it is advisable to configure it so that the width W is a natural number multiple of . ４ If you want to make it as long as possible, the width Wd should be ４ Preferably, it is three times or less.

[0046] The door panel 120 has a frame portion 121 that enhances its durability against an increase in internal pressure. 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 operation function portion 90 and the opening 20h. The frame portion 121 and the reinforcing portion 20b enhance the pressure resistance of the door panel 120.

[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 includes a plate-like plate portion 80p and flange portions (81m, 82n) extending vertically from each of the four edges of the plate portion 80p. The lid extension panel 80 includes a flange portion 81m having a plurality of screw holes h along the longitudinal direction and a flat flange portion 82n having no screw holes h along the lateral direction.

[0049] The lid extension panel 80 has a lid flange 84 extending perpendicularly inward from the edge of each of the two flange portions 82n along the short side. The lid flange 84 has a plurality of screw holes h. More specifically, the lid flange 84 has at least one set of screw hole groups K. The lid flange 84 illustrated in each figure has one set of screw hole groups 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 plurality of 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 and nuts (the "flanges" in this expression include the flange portions of each panel, the connecting flange 34, the three-sided flange 74, and the lid flange 84).

[0050] In the case of an oxygen room intended for people to enter, the prefabricated room 200 has a height Td, a height T ３ , and height T ４ is 1920 mm, thickness Sd, thickness S ３ , and thickness S ４ is 60 mm, width Wd is 960 mm, width W ３ is 540 mm, width W ４ In this case, the length T ７ and length T ８ is 2040 mm, and the width W ７ is 540 mm, and the width W ８ The thickness S of the cover panel 170 is 480 mm. ７ If the distance between the panels is 60 mm, the overall size of the prefabricated room 200 will be 2040 mm in height, 3000 mm in width, and 2040 mm in depth. However, these dimensions can be changed as appropriate. The prefabricated room 200 of the second embodiment is designed so that each panel is joined to the adjacent panels by bolts and nuts (not shown) through the 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 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, while 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 rear side of the door panel 120 can be repositioned in the same way as in Figures 18 to 22, and the left side can be repositioned in the same way as in Figures 23 to 27.

[0053] Although Figures 18 to 22 show an example in which the peripheral wall panel 130 is disposed on the short side of the peripheral wall 110, 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 Figure 18 and the bottom right of Figure 22). The same applies to the peripheral walls 110 illustrated in Figures 23 to 27. For example, the peripheral wall panel 130 in the upper right of Figure 23 may be swapped with the adjacent peripheral wall extension panel 140 in the long direction, as shown in Figure 24. Furthermore, the peripheral wall panel 130 on the right side of Figure 25 may be swapped with the adjacent peripheral wall extension panel 140 in the long direction, as shown in Figure 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. Furthermore, 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, because 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, the overall position of the screw holes h does not change even if the position of the door panel 120 is changed. Therefore, the prefabricated room 200 can use the same lid panel 170 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 Figures 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 Figure 29, when four peripheral wall extension panels 140 are arranged behind the peripheral wall 110, the peripheral wall 110 has a square shape in plan view. The peripheral wall 110 illustrated in Figure 29 may also have a size where two peripheral wall extension panels 140 are arranged behind the peripheral wall 110. When it is desired to increase or decrease the depth of the prefabricated room 200, it is advisable to increase or decrease the number of peripheral wall extension panels 140 in the depth direction, as shown in Figure 30. When such a configuration is adopted, the length T of the lid panel 170 ７ and the length T of the lid extension panel 80 ８29 and 30, the position of the door panel 120 can be freely changed without changing the arrangement of the screw holes h on the entire peripheral wall 110, as in the examples of FIGS.

[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 knockdown room 200 of the second embodiment includes a plurality of 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 that make up the peripheral wall 110. The door panel 120, the peripheral wall panel 130, and the peripheral wall extension panel 140 are all equal in height and thickness. The width W of the peripheral wall panel 130 is ３ is the width W of the peripheral wall extension panel 140 ４ The width Wd of the door panel 120 is longer than the width W of the peripheral wall extension panel 140 by the thickness Sd of the door panel 120. ４The peripheral wall panel 130 has a connecting flange 34 that extends vertically inward from the edge of one of two flange portions arranged along the height direction. Therefore, by combining panels with a simple structure, the location of the entrance and exit of the prefabricated room 200 can be freely changed.

[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 knockdown room 200 according to the second embodiment, the width W of the cover panel 70 is ７ is the width W of the peripheral wall panel 130 ３ The width W of the lid extension panel 80 is equal to ８ is the width W of the peripheral wall extension panel 140 ４ Here, one lid extension panel 80 and two peripheral wall extension panels 140 are referred to as an expansion unit. The width of the prefabricated room 200 can be easily expanded or reduced by adding or removing expansion units. 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 lid panels 170 and lid extension panels 80 of the same material, structure, and number. However, the prefabricated room 200 may use different panels for the top wall 150 and the bottom wall 160, depending on the material, structure, and number of panels. 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 prefabricated 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 each composed of two lid panels 70. However, this is not limiting. For example, at least one of the top wall 50 and the bottom wall 60 may be composed of a single panel that is the same size as the two lid panels 70 combined and can be connected to other panels in the same manner. This 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 composed 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 composed of a single panel. The number of screw holes h included in the screw hole group K in each panel that makes up the prefabricated rooms 100 and 200 is not limited to the examples shown in the figures, 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 shows an example of a screw hole group K that is made up of an even number of screw holes h, the screw hole group K may also be made up 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 knockdown room 100 or 200 may be configured to have only one peripheral wall extension panel 40 or 140 as shown in FIG. 31. In this case, the width Wd of the door panel 20 or 120 is equal to the width W of the peripheral wall extension panel 40 or 140. ４Even with this configuration, the knockdown rooms 100 and 200 can have the door panels 20 or 120 arranged in either the short-side direction or the long-side direction, as shown in Figures 31(a) to 31(c).

[0064] While the figures primarily 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 and 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 wall, and the door panel (20, 120) in Figure 32(b) may be located on the right side of the rear wall.

[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, in conventional prefabricated rooms, if the panel location needs to be changed during or after assembly, the entire room must be disassembled and reassembled. In this regard, the prefabricated rooms 100 and 200 allow the location of an entrance / exit to be easily changed by simply changing the location of some panels, even during assembly. The prefabricated rooms 100 and 200 may be hollow rectangular parallelepiped or hollow cubic.

[0066] The prefabricated looms 100 and 200 may be designed to be assembled using other fastening members instead of bolts and nuts. For example, the prefabricated looms 100 and 200 may be designed to be assembled using rivets. In this case, each panel may be provided with holes for inserting rivets instead of the multiple screw holes h. Furthermore, the prefabricated looms 100 and 200 may be designed to be assembled using clamps that clamp and secure the flanges of each panel together. Alternatively, the prefabricated looms 100 and 200 may be designed to secure the flanges of each panel together using the magnetic force of magnets. In this case, magnets may be embedded in the flanges of each panel, or two adjacent flanges may be secured by clamping them with one or more pairs of magnets. However, the prefabricated looms 100 and 200 may also be designed to secure the flanges of each panel together by welding. When using clamps, magnets, or welding, the panels do not need to be provided with multiple holes such as screw holes h. However, the prefabricated rooms 100 and 200 may be constructed by combining the above specifications.

[0067] The panels constituting the prefabricated rooms 100 and 200 are not limited to the above examples and can be formed from a variety of materials. The prefabricated rooms 100 and 200 may employ aluminum, titanium, carbon, or the like as the primary material for each panel. The shape and size of the reinforcing members in each panel may be appropriately modified 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] It is anticipated that one or both of the pressurizing means and the operating function unit 90 may be sold separately from each panel, and therefore 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.
