Modes for Carrying Out the Invention

[0018] [First Embodiment] Hereinafter, with reference to FIGS. 1 to 5, a shielding structure 1 of an opening according to the first embodiment of the present invention (hereinafter simply referred to as "shielding structure") will be described. In the present embodiment, the right side in FIG. 1 is described as "the right side of the shielding structure 1", and the front side of the paper surface in FIG. 1 (the left side in FIG. 2) is described as "the front of the shielding structure 1".

[0019] As shown in FIGS. 1 to 3, the shielding structure 1 is configured to shield a large opening Wa formed in a wall body W erected on a floor surface F in a large-scale facility such as a power plant. In the present embodiment, the shielding structure 1 is arranged such that the front faces the outside of the wall body W. In the shielding structure 1, each member such as the door 2 is formed of a steel material such as highly corrosion-resistant stainless steel (hot-rolled stainless steel plate or cold-rolled stainless steel plate).

[0020] The shielding structure 1 according to the present embodiment includes a door 2 which is an opening / closing member that can open and close a lower opening 4L (see FIG. 5) which is a part of the opening Wa, and a panel member 3 that closes an upper opening 4H (see FIG. 5) which is another part of the opening Wa. Hereinafter, the assembly configuration of the door 2 and the panel member 3 in the opening Wa of the wall body W will be described in order.

[0021] As shown in FIGS. 2 and 3, a plurality of frames are fixed to the opening Wa for assembling the door 2 and the panel member 3. Each frame is fixed to the wall body W by an anchor bolt or the like. A buffer member C is inserted between each frame and the wall body W, and the portion where the buffer member C is exposed to the outside is covered with a sealing material S.

[0022] In the present embodiment, as frames, a lower frame 41, a left door frame 42, a right door frame 43, a frame member 44, a left panel frame 45, a right panel frame 46, and an upper frame 47 are provided (see FIG. 5). Each frame is configured by combining a plurality of plate materials.

[0023] As shown in FIGS. 2 and 3, the lower frame 41 is provided at the lower end of the opening Wa along the floor surface F. Also, the left door frame 42 is provided on the left side of the front surface in the lower half of the opening Wa. As shown in FIG. 3(b), the left front surface of the left door frame 42 is covered with the door cover portion 42a. Also, the right door frame 43 is provided on the right side in the lower half of the opening Wa.

[0024] Also, as shown in FIGS. 2 and 3, the left panel frame 45 is provided on the left side of the front surface in the upper half of the opening Wa. As shown in FIG. 3(a), the left front surface of the left panel frame 45 is covered with the panel cover portion 45a. Also, the right panel frame 46 is provided on the right side in the upper half of the opening Wa. Also, the upper frame 47 is provided at the upper end of the opening Wa.

[0025] In the shielding structure 1 according to the present embodiment, as shown in FIG. 2, a frame member 44 is provided as a frame body interposed between the door 2 and the panel member 3. In the present embodiment, the frame member 44 is detachably arranged with respect to the opening Wa so as to divide the opening Wa into two upper and lower compartments. As shown in FIG. 4, the frame member 44 is integrally formed by combining an upper frame member 44U and a lower frame member 44D and being fastened with bolts.

[0026] In the shielding structure 1 according to the present embodiment, as shown in FIG. 4, the upper frame member 44U and the lower frame member 44D are combined vertically in the frame member 44. Thereby, since the frame member 44 is configured to have a thickness in the front-rear direction, the load-bearing property in the front-rear direction is increased. That is, the frame member 44 has pressure resistance when pressure is applied to the door 2 and the panel member 3 in the shielding structure 1. In addition, in the shielding structure 1 according to the present embodiment, it is also possible to adopt an H-shaped steel as the frame member 44.

[0027] As described above, in the shielding structure 1 according to the present embodiment, the opening Wa of the wall body W is vertically partitioned by the frame member 44. Then, as shown in FIG. 5, the lower opening 4L is formed in the lower half of the opening Wa by the lower frame 41, the left door frame 42, the right door frame 43, and the frame member 44 (lower side frame member 44D). Similarly, the upper opening 4H is formed in the upper half of the opening Wa by the frame member 44 (upper side frame member 44U), the left panel frame 45, the right panel frame 46, and the upper frame 47.

[0028] As shown in FIGS. 2 and 3, protrusions surrounding the peripheries of the door 2 and the panel member 3 are provided on the front surfaces of the respective frames. Specifically, lower frame protrusions 51, left door frame protrusions 52, right door frame protrusions 53, frame member protrusions 54 (upper side frame member protrusions 54U and lower side frame member protrusions 54D), left panel frame protrusions 55, right panel frame protrusions 56, and upper frame protrusions 57 are provided on the front surfaces of the lower frame 41, the left door frame 42, the right door frame 43, the frame member 44 (upper side frame member 44U and lower side frame member 44D), the left panel frame 45, the right panel frame 46, and the upper frame 47, respectively.

[0029] As shown in FIGS. 1 and 3(b), the door 2 is assembled to the left door frame protrusion 52 via two hinges 23·23. The door 2 is formed by joining steel plates provided on the front surface side and the back surface side via a plurality of connecting members. A closing portion 21, which is a rectangular plate body, is provided at the front portion of the door 2. An outer handle 25a is fixed to the outer surface of the closing portion 21. The outer shape (the shapes of the upper and lower ends and the left and right ends) of the closing portion 21 is formed larger than the lower opening 4L.

[0030] A contact surface 21a is formed at the outer edge portion on the rear surface of the closing portion 21. Since the closing portion 21 is formed larger than the lower opening 4L, when the door 2 closes the lower opening 4L, the contact surface 21a contacts the front surfaces of the respective frames.

[0031] At the rear of the door 2 (behind the closing portion 21), an insertion portion 22 having an outer shape slightly smaller than that of the lower opening 4L is formed. An internal space is formed inside the insertion portion 22. When the door 2 closes the lower opening 4L, the insertion portion 22 is inserted inside the lower opening 4L. An inner handle 25b is fixed to the inner surface of the insertion portion 22. Taper rods 26 extend from the left and right outer side surfaces of the insertion portion 22. The taper rods 26 are configured to move forward and backward in the left - right direction by the operation of the handle 24 by the user.

[0032] In the left door frame 42 and the right door frame 43, pressure - receiving pins 48 are provided at positions facing the taper rods 26. When the taper rod 26 is further displaced in the direction of the pressure - receiving pin 48, as shown in Fig. 3(b), the tapered surface abuts against the pressure - receiving pin 48, and the tapered surface of the taper rod 26 presses the pressure - receiving pin 48 forward (the opening side of the door 2). Since the pressure - receiving pins 48 are fixed to the left door frame 42 and the right door frame 43, the taper rod 26 receives the reaction force from the pressure - receiving pins 48 and is displaced backward (the closing side of the door 2). Thereby, a force toward the closing side is generated on the door 2, and the door 2 and the frame body are in close contact.

[0033] In the shielding structure 1 according to the present embodiment, as shown in Figs. 3(b) and 4, the door 2 is arranged such that a gap is formed between the door 2 and the frame body when the door 2 is closed. And, the contact surface 21a of the door 2 and the front surface of the frame body are provided with an annular door seal portion 60 which is a watertight member for blocking the intrusion of liquid from the gap between the door 2 and the frame body.

[0034] Specifically, as shown in Fig. 4, a first door seal member 61 and a second door seal member 62 are fixed to the front surface of the frame body. Also, a third door seal member 63 is fixed to the contact surface 21a. Each seal member is arranged at a position facing the case of the opposing seal member.

[0035] When the user rotates the handle 24 to tighten the door 2 against the frame body, as shown in Fig. 4, the cases of the respective seal members elastically deform the first door seal member 61, the second door seal member 62, and the third door seal member 63, and the space between the door 2 and the frame body is sealed.

[0036] As shown in FIGS. 3(a) and 4, on the upper frame member 44U, the panel left frame 45, the panel right frame 46, and the upper frame 47 that form the upper opening 4H, a panel fixing portion 58 is provided so as to surround the upper opening 4H. The panel member 3 is fixed to the panel fixing portion 58 using a fixture such as a bolt.

[0037] In the shielding structure 1 according to the present embodiment, as shown in FIGS. 3(a) and 4, the panel member 3 is arranged such that a gap is formed between the panel member 3 and the frame body when it is closed. And, between the rear surface of the panel member 3 and the front surface of the frame body, an annular panel seal portion 70, which is a watertight member that blocks the intrusion of liquid from the gap between the panel member 3 and the frame body, is provided.

[0038] Specifically, as shown in FIG. 4, a first panel seal member 71 and a second panel seal member 72 are fixed to the front surface of the frame body. Also, a third panel seal member 73 is fixed to the rear surface of the panel member 3. Each seal member is arranged at a position facing the case of the opposing seal member.

[0039] When the panel member 3 is fixed to the panel fixing portion 58 by bolts, as shown in FIG. 4, the cases of the respective seal members elastically deform the first panel seal member 71, the second panel seal member 72, and the third panel seal member 73, and the space between the panel member 3 and the frame body is sealed.

[0040] As described above, in the shielding structure 1 according to the present embodiment, the door 2, which is an opening / closing member, and the panel member 3 are arranged such that a gap is formed between them and the frame body when it is closed. Also, the door 2 and the panel member 3 are provided with a door seal portion 60 and a panel seal portion 70 as watertight members that block the intrusion of liquid from this gap.

[0041] As described above, according to the present embodiment, the configuration of the shielding structure 1 is divided into the door 2, which is an opening / closing member, and the panel member 3. As a result, compared with a configuration that entirely shields a large opening Wa, each member can be made more compact, so that the manufacturing cost of the shielding structure 1 can be suppressed. Further, since the door seal portion 60 and the panel seal portion 70, which are watertight members that block the intrusion of liquid from the gaps between the door 2 and the panel member 3 and the frame body, are provided, the overall watertightness of the shielding structure 1 can be ensured.

[0042] Further, in the shielding structure 1 according to the present embodiment, the frame member 44 is detachably disposed with respect to the opening Wa so as to divide the opening Wa into two upper and lower compartments (upper opening 4H and lower opening 4L). And each of the door 2 and the panel member 3 can close at least one of the upper and lower compartments. In the present embodiment, the door 2 can close the lower opening 4L, and the panel member 3 can close the upper opening 4H.

[0043] According to the shielding structure 1 according to the present embodiment, by removing the frame member 44, the opening Wa can be used in its original size. That is, when carrying a large part or the like that cannot pass through the lower opening 4L when the door 2 is opened (the same applies to the upper opening 4H when the panel member 3 is removed), by removing the door 2, the panel member 3, and the frame member 44, the part or the like can pass through the opening Wa.

[0044] Further, in the shielding structure 1 according to the present embodiment, the frame member 44 has pressure resistance when pressure is applied to the door 2 and the panel member 3. As a result, even when the shielding structure 1 receives a large load such as a tsunami on the door 2 or the panel member 3, its strength can be maintained.

[0045] [Second Embodiment] Next, with reference to FIGS. 6 to 8, the shielding structure 100 according to the second embodiment of the present invention will be described. In the present embodiment, the right side in FIG. 6 is described as the "right side of the shielding structure 100", and the front side of the paper surface in FIG. 6 (the left side in FIG. 7) is described as the "front of the shielding structure 100". Further, in the following embodiments, detailed descriptions of the configurations similar to those of the shielding structure 1 according to the first embodiment described above will be omitted, and the description will focus on the configurations different from those of the above embodiments.

[0046] As shown in FIGS. 6 to 8, the shielding structure 100 according to the present embodiment includes a door 2 which is an opening / closing member that can open and close a first opening 4A which is a part of the opening Wa, and a lower panel member 3L and an upper panel member 3H which close a second opening 4B and a third opening 4C which are the other parts of the opening Wa. Hereinafter, the assembling configurations of the door 2, the lower panel member 3L, and the upper panel member 3H in the opening Wa of the wall body W will be described in order.

[0047] As shown in FIGS. 7 and 8, a plurality of frames are fixed to the opening Wa for assembling the door 2 and the panel members 3L and 3H. In the present embodiment, as the frames, a lower frame 81, a lower right frame 82, a lower left frame 83, a first frame member 84, an upper right frame 85, an upper left frame 86, an upper frame 87, and a second frame member 88 are provided. Each frame is configured by combining a plurality of plate materials.

[0048] As shown in FIGS. 7 and 8, the lower frame 81 is provided at the lower end portion of the opening Wa in the vicinity of the floor surface F. Further, the lower right frame 82 is provided on the right side in the lower half of the opening Wa. As shown in FIG. 8(b), the right front surface of the lower right frame 82 is covered with a door cover portion 82a. Further, the lower left frame 83 is provided on the left side in the lower half of the opening Wa.

[0049] Further, as shown in FIGS. 7 and 8, the upper right frame 85 is provided on the right side in the upper half of the opening Wa. Further, the upper left frame 86 is provided on the left side in the upper half of the opening Wa. Further, the upper frame 87 is provided at the upper end portion of the opening Wa.

[0050] In the shielding structure 100 according to the present embodiment, as shown in FIG. 7, a first frame member 84 is provided as a frame body interposed between the door 2 and the upper panel member 3H. In the present embodiment, the first frame member 84 is detachably arranged with respect to the opening Wa so as to divide the opening Wa into two upper and lower sections. Further, in the shielding structure 100, as shown in FIG. 6, a second frame member 88 is provided as a frame body interposed between the door 2 and the lower panel member 3L. In the present embodiment, the second frame member 88 is detachably arranged with respect to the opening Wa so as to divide the section below the first frame member 84 into left and right sections.

[0051] In the shielding structure 100 according to the present embodiment, as shown in FIGS. 7 and 8, the first frame member 84 and the second frame member 88 are configured to have a thickness in the front-rear direction, so that the load-bearing property in the front-rear direction is enhanced. That is, the first frame member 84 and the second frame member 88 have pressure resistance when pressure is applied to the door 2, the lower panel member 3L, and the upper panel member 3H in the shielding structure 100.

[0052] As described above, in the shielding structure 100 according to the present embodiment, the opening Wa of the wall body W is divided into three regions by the first frame member 84 and the second frame member 88. Then, as shown in FIG. 6, a first opening 4A is formed at the lower right of the opening Wa by the lower frame 81, the lower right frame 82, the first frame member 84, and the second frame member 88. Similarly, a second opening 4B is formed at the lower left of the opening Wa by the lower frame 81, the lower left frame 83, the first frame member 84, and the second frame member 88. Further, a third opening 4C is formed at the upper part of the opening Wa by the first frame member 84, the upper right frame 85, the upper left frame 86, and the upper frame 87.

[0053] As shown in FIGS. 7 and 8, protrusions surrounding the peripheries of the door 2 and the panel members 3L and 3H are provided on the front surfaces of the respective frame bodies. Specifically, lower frame protrusions 91, lower right frame protrusions 92, lower left frame protrusions 93, first frame member protrusions 94, upper right frame protrusions 95, upper left frame protrusions 96, upper frame protrusions 97, and second frame member protrusions 98 are provided on the front surfaces of the lower frame 81, the lower right frame 82, the lower left frame 83, the first frame member 84, the upper right frame 85, the upper left frame 86, the upper frame 87, and the second frame member 88, respectively.

[0054] As shown in FIGS. 6 and 8(b), the lower right frame protrusion 92 has two hinges 23·23 through which the door 2 is assembled. The door 2 is formed by joining steel plates provided on the front surface side and the back surface side via a plurality of connecting members. A closing portion 21, which is a rectangular plate body, is provided at the front portion of the door 2. An outer handle 25a is fixed to the outer surface of the closing portion 21. The outer shape (the shape of the upper and lower ends and the left and right ends) of the closing portion 21 is formed to be larger than that of the first opening 4A.

[0055] A contact surface 21a is formed on the outer edge portion of the rear surface of the closing portion 21. Since the closing portion 21 is formed to be larger than the first opening 4A, when the door 2 closes the first opening 4A, the contact surface 21a contacts the front surface of each frame body.

[0056] In the shielding structure 100 according to the present embodiment, as shown in FIG. 8(b), the door 2 is arranged so that a gap is formed between the door 2 and the frame body when the door 2 is closed. And the contact surface 21a of the door 2 and the front surface of the frame body are provided with an annular door seal portion 60 which is a watertight member for blocking the intrusion of liquid from the gap between the door 2 and the frame body.

[0057] As shown in FIGS. 8(a) and (b), panel fixing portions 99 are provided around the second opening 4B and the third opening 4C. The upper panel member 3H and the lower panel member 3L are fixed to each panel fixing portion 99 using fixtures such as bolts.

[0058] In the shielding structure 100 according to the present embodiment, as shown in FIGS. 8(a) and (b), the panel members 3H·3L are arranged so that a gap is formed between the panel members 3H·3L and the frame body when the panel members 3H·3L are closed. And the rear surface of the upper panel member 3H and the front surface of the frame body are provided with an upper panel seal portion 70H which is a watertight member for blocking the intrusion of liquid from the gap between the upper panel member 3H and the frame body. Similarly, the rear surface of the lower panel member 3L and the front surface of the frame body are provided with a lower panel seal portion 70L which is a watertight member for blocking the intrusion of liquid from the gap between the lower panel member 3L and the frame body.

[0059] As described above, in the shielding structure 100 according to the present embodiment, the door 2 as an opening / closing member and the panel members 3H and 3L are arranged so that a gap is formed between them and the frame body when closed. Further, the door 2 and the panel members 3H and 3L are provided with a door seal portion 60 and panel seal portions 70H and 70L as watertight members for blocking the intrusion of liquid from this gap.

[0060] As described above, according to the present embodiment, the configuration of the shielding structure 100 is divided into the door 2 as an opening / closing member, the upper panel member 3H, and the lower panel member 3L. Thereby, compared with the configuration for entirely shielding the large opening Wa, each member can be made more compact, so that the manufacturing cost of the shielding structure 100 can be suppressed. Further, since the door seal portion 60 and the panel seal portions 70H and 70L, which are watertight members for blocking the intrusion of liquid from the gaps between the door 2 and the panel members 3H and 3L and the frame body, are provided, the overall watertightness of the shielding structure 100 can also be ensured.

[0061] Further, in the shielding structure 100 according to the present embodiment, the first frame member 84 and the second frame member 88 are detachably arranged with respect to the opening Wa so as to divide the opening Wa into three compartments (the first opening 4A, the second opening 4B, and the third opening 4C). And each of the door 2 and the panel members 3H and 3L can close at least one of the three compartments. In the present embodiment, the door 2 can close the first opening 4A, the lower panel member 3L can close the second opening 4B, and the upper panel member 3H can close the third opening 4C.

[0062] According to the shielding structure 100 according to the present embodiment, by removing the first frame member 84 and the second frame member 88, the opening Wa can be used in its original size. That is, when carrying a large component or the like that cannot pass through the first opening 4A when the door 2 is opened (the same applies to the second opening 4B and the third opening 4C when the panel members 3H and 3L are removed), by removing the door 2, the panel members 3H and 3L, the first frame member 84, and the second frame member 88, the component or the like can pass through the opening Wa.

[0063] Further, in the shielding structure 100 according to the present embodiment, the first frame member 84 and the second frame member 88 have pressure resistance when pressure is applied to the door 2 and the panel members 3H and 3L. Thereby, even when the shielding structure 100 receives a large load such as a tsunami on the door 2 or the panel members 3H and 3L, its strength can be maintained.

[0064] Also, in the shielding structure 100 according to the present embodiment, a plurality of (two in this embodiment) panel members 3H and 3L are assembled to one first frame member 84. Thereby, in this embodiment, it is possible to configure the shielding structure with a smaller number of frame members as compared with a configuration including frame members corresponding to the number of panel members.

[0065] [Third Embodiment] Next, with reference to FIG. 9, a shielding structure 200 according to the third embodiment of the present invention will be described. In the embodiments after this embodiment, since the number and arrangement configuration of the frame members and the panel members are different from those of the shielding structure 100 according to the second embodiment, the description will focus on these.

[0066] As shown in FIG. 9, the shielding structure 200 according to the present embodiment includes a door 2 that is an opening / closing member for making a part of an opening in the wall body W openable / closable, and a first panel member 3A, a second panel member 3B, a third panel member 3C, a fourth panel member 3D, and a fifth panel member 3E that close the other part of the opening. Hereinafter, the assembly configuration of the door 2 and the first to fifth panel members 3A to 3E in the opening of the wall body W will be described in order.

[0067] As shown in FIG. 9, a plurality of frames are fixed to the opening of the wall body W for assembling the door 2 and the first to fifth panel members 3A to 3E. In this embodiment, as the frames, a lower frame 201, a left frame 202, a right frame 203, an upper frame 204, a first frame member 205, a second frame member 206, a third frame member 207, a fourth frame member 208, and a fifth frame member 209 are provided. Each frame is configured by combining a plurality of plate members.

[0068] In the shielding structure 200 according to the present embodiment, as shown in FIG. 9, the first frame member 205 is detachably disposed with respect to the opening so as to divide the opening into two upper and lower compartments. Further, in the shielding structure 200, a second frame member 206 and a third frame member 207 are provided between the first frame member 205 and the lower frame 201. The second frame member 206 and the third frame member 207 are detachably disposed with respect to the opening so as to divide the region below the first frame member 205 into three compartments in the left - right direction.

[0069] Further, in the shielding structure 200, a fourth frame member 208 and a fifth frame member 209 are provided between the first frame member 205 and the upper frame 204. The fourth frame member 208 and the fifth frame member 209 are detachably disposed with respect to the opening so as to divide the region above the first frame member 205 into three compartments in the left - right direction.

[0070] As described above, in the shielding structure 200 according to the present embodiment, the opening of the wall body W is divided into six regions by the first to fifth frame members 205 to 209. And as shown in FIG. 9, each region is closed by the door 2 and the first to fifth panel members 3A to 3E.

[0071] As described above, according to the present embodiment, the configuration of the shielding structure 200 is divided into the door 2 which is an opening - closing member and the first to fifth panel members 3A to 3E. Thereby, compared with a configuration that entirely shields a large opening, each member can be made compact, so that the manufacturing cost of the shielding structure 200 can be suppressed. Further, the door 2 and the first to fifth panel members 3A to 3E are each configured to include a seal portion which is a watertight member, similar to the above - described embodiments. Therefore, the overall watertightness of the shielding structure 200 can also be ensured.

[0072] [Fourth Embodiment] Next, with reference to FIG. 10, the shielding structure 300 according to the fourth embodiment of the present invention will be described. As shown in FIG. 10, the shielding structure 300 according to the present embodiment includes a door 2 which is an opening / closing member that can open and close a part of the opening in the wall body W, and a first panel member 3A, a second panel member 3B, a sixth panel member 3F, and a seventh panel member 3G that close the other parts of the opening. Hereinafter, the assembly configuration of the door 2 and the first to seventh panel members 3A to 3G in the opening of the wall body W will be described in order.

[0073] As shown in FIG. 10, a plurality of frames are fixed to the opening of the wall body W for assembling the door 2 and the first to seventh panel members 3A to 3G. In the present embodiment, as the frames, a lower frame 301, a left frame 302, a right frame 303, an upper frame 304, a first frame member 305, a second frame member 306, a third frame member 307, and a fourth frame member 308 are provided. Each frame is configured by combining a plurality of plate materials.

[0074] In the shielding structure 300 according to the present embodiment, as shown in FIG. 10, the first frame member 305 and the second frame member 306 are detachably arranged with respect to the opening so as to divide the opening into three sections in the vertical direction. Further, in the shielding structure 300, a third frame member 307 and a fourth frame member 308 are provided between the first frame member 305 and the lower frame 301. The third frame member 307 and the fourth frame member 308 are detachably arranged with respect to the opening so as to divide the area below the first frame member 305 into three sections in the left-right direction.

[0075] As described above, in the shielding structure 300 according to the present embodiment, the opening of the wall body W is divided into five areas by the first to fourth frame members 305 to 308. And as shown in FIG. 10, each area is closed by the door 2 and the first to seventh panel members 3A to 3G.

[0076] As described above, according to the present embodiment, the configuration of the shielding structure 300 is divided into the door 2 which is an opening / closing member, and the first to seventh panel members 3A to 3G. Thereby, compared with the configuration that entirely shields a large opening, each member can be made compact, so that the manufacturing cost of the shielding structure 300 can be suppressed. Further, the door 2 and the first to seventh panel members 3A to 3G are each configured to include a seal portion which is a watertight member, in the same manner as each of the above embodiments. For this reason, the overall watertightness in the shielding structure 300 can also be ensured.

[0077] Further, according to the shielding structure 300 according to the present embodiment, compared with the panel members of the shielding structure 200 according to the above embodiment, the longitudinal dimensions of the sixth panel member 3F and the seventh panel member 3G are increased. For this reason, when one or both of the sixth panel member 3F and the seventh panel member 3G are removed, it becomes possible to allow large components or the like that cannot pass through the opening even if other panel members are removed, to pass through the opening.

[0078] [Modification Example] The above embodiment can be appropriately modified as shown in the following modification examples. Note that each modification example may be applied in combination with other modification examples as long as no contradiction occurs.

[0079] In each of the above embodiments, a door 2 is provided as an opening / closing member for making a part of the opening Wa openable / closable. However, it is also possible to provide a closing member for making a part of the opening Wa closable instead of the opening / closing member. For example, it is also possible to provide a closing plate instead of the door 2 at the location where the door 2 is provided in the above embodiment, and to configure to close a part of the opening Wa with the closing plate.

[0080] Further, as an opening / closing structure when an opening / closing member is provided in a part of the opening Wa, in addition to the hinged door structure that can be rotated like the door 2 in each of the above embodiments, a sliding door structure that can be displaced horizontally, a lift door structure that can be displaced vertically, etc. can also be adopted.

[0081] Alternatively, it is also possible to configure the frame member provided in the opening Wa to be fixed to the wall body W without being detachable. Also, as in the first embodiment, it is acceptable to configure to assemble one panel member to one frame member, or as in the second to fourth embodiments, to configure to assemble a plurality of panel members to one frame member. Further, regarding the door as the opening / closing member, the closing member, and the panel member, it is also possible to make their thickness, height dimension, width dimension, material, etc. different from those in this embodiment.
