This canopy building is equipped with aluminum alloy wall units that form wall surfaces surrounding it on all four sides. The wall units are composed of a front unit, a rear unit, a right side unit, and a left side unit. The canopy building also includes a plurality of aluminum alloy beam members having truss structural parts whose both ends are fixed to the front unit and the rear unit, and a roof member installed on the beam members. In addition, a plurality of aluminum alloy frame bodies are joined to the edges of the wall units, and reinforcing diagonal members are attached diagonally to opposing corners of the rectangular frame bodies. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6895191 Summary of the Invention [Problem to be solved by the invention]

[0004] In the canopy building described in Patent Document 1, reinforcing diagonal members are installed diagonally on a rectangular frame body joined to the edge of the wall unit, thereby achieving performance that can withstand live loads, wind pressure, and earthquakes. The aluminum alloy wall unit itself does not function as a structural material such as a bearing wall.

[0005] For example, in the case of small, simple buildings such as telephone booths, when aluminum alloy wall panels are used, attaching reinforcing diagonal members to the frame body increases the number of construction steps and raises costs.

[0006] The present invention has been made in consideration of the above problems, and aims to provide a box unit structure that does not require reinforcing diagonal members in a configuration using wall panels made of aluminum alloy. [Means for solving the problem]

[0007] In order to solve the above problems, the box unit structure according to the first aspect comprises an aluminum alloy wall panel, a pair of pillars each having a first groove on the wall panel side, a pair of horizontal members each joined to the pair of pillars at both longitudinal sides and each having a second groove on the wall panel side, a first setting block provided inside the first groove against which an edge of the wall panel inserted into the first groove abuts, thereby fixing the wall panel to the pair of pillars, and a second setting block provided inside the second groove against which an edge of the wall panel inserted into the second groove abuts, thereby fixing the wall panel to the pair of horizontal members.

[0008] The box unit structure according to the first aspect includes an aluminum alloy wall panel, a pair of columns having a first groove on the wall panel side, and a pair of horizontal members joined to the columns on both longitudinal sides and having a second groove on the wall panel side. The wall panel is fixed to the columns by abutting the edge of the wall panel inserted into the first groove with a first setting block provided inside the first groove of the pair of columns. Furthermore, the wall panel is fixed to the horizontal members by abutting the edge of the wall panel inserted into the second groove with a second setting block provided inside the second groove of the pair of horizontal members. This allows the aluminum alloy wall panel to function as a bearing wall and resist compressive forces. In other words, using the aluminum alloy wall panel as a structural member such as a bearing wall can achieve performance that can withstand live loads, wind pressure, and earthquakes. Furthermore, because the wall panel functions as a structural member such as a bearing wall, diagonal members are not required.

[0009] The box unit structure according to a second aspect is the box unit structure according to the first aspect, wherein the first setting block and the second setting block are made of resin or rubber.

[0010] According to the box unit structure of the second aspect, the first setting block and the second setting block are made of resin or rubber, so rattle of the wall panel relative to the pair of pillars or the pair of cross members is suppressed.

[0011] The box unit structure described in the third aspect is the box unit structure described in the first or second aspect, in which a total of four first setting blocks and four second setting blocks are arranged at the corners of the wall panel.

[0012] According to the box unit structure described in the third aspect, a total of four first setting blocks and four second setting blocks are arranged at the corners of the wall panel, thereby suppressing rattling of the wall panel relative to a pair of pillars or a pair of cross members.

[0013] The box unit structure described in the fourth aspect is the box unit structure described in the first or second aspect, in which the first setting block and the second setting block are elongated members and are positioned in contact with the four sides of the wall panel.

[0014] According to the box unit structure of the fourth aspect, the first setting block and the second setting block are elongated members arranged in positions that contact the four sides of the wall panel, thereby suppressing rattling of the wall panel relative to a pair of pillars or a pair of cross members.

[0015] The box unit structure described in the fifth aspect is the box unit structure described in the first aspect, in which a first caulking material that maintains airtightness between the wall panel and the pillar is provided on the opening side of the first setting block in the first groove portion, and a second caulking material that maintains airtightness between the wall panel and the cross member is provided on the opening side of the second setting block in the second groove portion.

[0016] According to the box unit structure of the fifth aspect, the first caulking material and the second caulking material ensure airtightness between the pair of pillars or the pair of horizontal members and the wall panel. [Effects of the Invention]

[0017] According to the present invention, no reinforcing diagonals are required in constructions using aluminum alloy wall panels. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In each drawing, elements that are less relevant to the present invention are omitted.

[0020] [First embodiment] Fig. 1 is a perspective view showing the door side of a building 10 to which a box unit structure S2 according to the first embodiment is applied, and Fig. 2 is a perspective view showing a state in which the door of the building 10 is open. Fig. 3 is a perspective view showing the side opposite the door of the building 10, and Fig. 4 is a perspective view showing the interior of the building 10 with the door side portion removed.

[0021] (Overall structure of the building) 1 to 4, a building 10 to which the box unit structure S2 is applied comprises a rectangular bottom surface 12 in a plan view, and a front surface unit 14, one side surface unit 16, the other side surface unit 18, and a rear surface unit 20 that rise from the bottom surface 12 and surround the four sides. The building 10 further comprises a roof unit 22 that is attached to the upper ends of the front surface unit 14, one side surface unit 16, the other side surface unit 18, and the rear surface unit 20 and covers the interior of the building 10.

[0022] Buildings 10 to which the box unit structure S2 is applied are used, for example, as telephone booths, river management facilities, or coastal conservation facilities. Examples of river management facilities include gate facilities such as weirs, headworks, sluice gates, culverts, and culverts, and pumping facilities such as drainage pumping stations, pumping stations, and clarifier stations. Examples of coastal conservation facilities include architectural structures constructed in conjunction with levees, revetments, sluice gates, and land barriers to manage these facilities.

[0023] (front unit) The front unit 14 includes a front wall 14A having a rectangular opening 15 (see FIG. 2) that is elongated in the vertical direction, and a door 30 that is attached to the front wall 14A and can open and close the opening 15. The door 30 is provided with a hinge (not shown) that is joined to the edge of the opening 15 at one widthwise end of the front wall 14A. The opening 15 can be opened and closed by rotating the other widthwise end of the door 30 toward and away from the front wall 14A using the hinge (not shown). The door 30 includes a frame 30A, a louver 30B provided on the lower side of the frame 30A, and a transparent panel 30C attached to the upper side of the frame 30A. The transparent panel 30C is made of transparent resin or glass.

[0024] (Side unit) As shown in FIGS. 1 to 4 and 6, one side unit 16 and the other side unit 18 have the same configuration, so only the side unit 16 will be described here. The side unit 16 includes two wall panels 40 made of aluminum alloy and three pillars 42 extending vertically and spaced apart laterally. The wall panels 40 are arranged side by side in the width direction at the bottom of the side unit 16. The three pillars 42 are arranged between the two wall panels 40 and on both sides of the two wall panels 40 in the width direction. In other words, the pillars 42 and the wall panels 40 are arranged alternately in the width direction of the side unit 16. In one wall panel 40, the two pillars 42 on both sides of the wall panel 40 in the width direction are an example of a pair of pillars. As an example, the middle pillar 42 is arranged above and below a horizontal member 44 on the outside of the building 10 (see FIG. 1), but is arranged continuously above and below the horizontal member 44 on the inside of the building 10 (see FIG. 4). The configuration of the pillar 42 is not limited to this and can be changed.

[0025] The side unit 16 also includes a horizontal member 44 disposed above the wall panel 40 and joined to a pair of adjacent columns 42, and a horizontal member 46 disposed below the wall panel 40 and joined to a pair of adjacent columns 42. The upper horizontal member 44 and the lower horizontal member 46 of one wall panel 40 in the vertical direction are an example of a pair of horizontal members. As an example, the upper horizontal member 44 of the wall panel 40 is disposed continuously across three columns 42 on the outside of the building 10 (see FIG. 1), while on the inside of the building 10, the horizontal member 44 is disposed split on both sides of the middle column 42 (see FIG. 4). Note that the configuration of the horizontal member 44 is not limited to this and can be changed. As an example, the lower horizontal member 46 of the wall panel 40 is disposed split on both sides of the middle column 42 on the outside of the building 10 (see FIG. 1), while on the inside of the building 10, the horizontal member 44 is disposed continuously across three columns 42 (see FIG. 4). The configuration of the cross member 46 is not limited to this and can be changed.

[0026] The three pillars 42 extend above the two wall panels 40. The side unit 16 is provided between adjacent pillars 42 and with two transparent panels 48 above the two wall panels 40 via cross members 44. The transparent panels 48 are arranged side by side in the width direction. The transparent panels 48 are made of transparent resin or glass.

[0027] Additionally, upper cross members 50 (portions covered by roof unit 22 in FIG. 1) are provided above the two transparent panels 48 and joined to the upper ends of the three pillars 42 (see FIG. 4). The structure for fixing the wall panels 40 to the side units 16, 18 will be described later.

[0028] (rear unit) 4 and 5, the rear unit 20 comprises a single wall panel 40 made of aluminum alloy and a pair of pillars 42 that are configured in common with the side units 16, 18. The rear unit 20 further comprises a horizontal member 54 that is disposed above the wall panel 40 and joined to the pair of pillars 42, and a horizontal member 56 that is disposed below the wall panel 40 and joined to an adjacent pair of pillars 42. The horizontal members 54 and 56 on both vertical sides of a single wall panel 40 are an example of a pair of horizontal members.

[0029] The rear unit 20 is provided with a transparent panel 58 and a louver section 60, which are disposed above the wall panel 40 via a horizontal member 54 between a pair of pillars 42. A vertical member 62 is provided between the transparent panel 58 and the louver section 60 and is disposed in the vertical direction. The transparent panel 58 is made of transparent resin or glass. An upper horizontal member 64 (the portion covered by the roof unit 22 in FIG. 5) is provided above the transparent panel 58 and the louver section 60 and is joined to the upper ends of the pair of pillars 42 (see FIG. 4). The structure for fixing the wall panel 40 to the rear unit 20 will be described later.

[0030] (Wall panel fixing structure) Next, a structure for fixing the wall panel 40, which is a main part of the box unit structure S2 of the first embodiment, will be described.

[0031] The structure for fixing the wall panels 40 in the side unit 16, side unit 18, and rear unit 20 of the building 10 is the same for each wall panel 40 provided in the side unit 16, side unit 18, and rear unit 20. Here, the structure for fixing one wall panel 40 in the side unit 16 will be described as an example. That is, in the side unit 16, the wall panel 40 is fixed to a pair of pillars 42 and a pair of cross members 44, 46.

[0032] FIG. 7 is a side view showing the configuration of the wall panel 40 and the vicinity of setting blocks 82 and 84 described later. FIG. 8 is a cross-sectional view taken along line 8A-8A in FIG. 6, showing a portion of the wall panel 40 where the setting block 82 is located on the lower side. FIG. 9(A) is a cross-sectional view taken along line 9A-9A in FIG. 6, showing a portion of the wall panel where there is no setting block on the upper side. FIG. 9(B) is a cross-sectional view taken along line 9B-9B in FIG. 6, showing a portion of the wall panel where the setting block 82 is located on the upper side. FIG. 10 is a cross-sectional view taken along line 10A-10A in FIG. 6, showing a portion of the wall panel 40 where the setting block 84 is located on the widthwise end side.

[0033] The wall panel 40 is made of a single plate material made of aluminum alloy (see FIG. 8). As an example, the thickness of the wall panel 40 is 2 mm or more and 5 mm or less. In the first embodiment, the thickness of the wall panel 40 is about 3 mm.

[0034] As shown in Figures 7 and 8, the cross member 46 has a groove 72 on the side facing the wall panel 40. That is, the groove 72 is open on the wall panel 40 side of the upper surface 46A (see Figure 8) of the cross member 46. A setting block 82 is provided inside the groove 72. The lower edge of the wall panel 40 inserted into the groove 72 abuts against the setting block 82. The groove 72 is an example of a second groove, and the setting block 82 is an example of a second setting block.

[0035] The setting block 82 is, for example, a rectangular parallelepiped member. The setting block 82 is made of resin or rubber. Examples of rubber include ethylene propylene rubber (EPDM-S), butadiene rubber (BR), chloroprene rubber (CR), butyl rubber (IIR), acrylonitrile butadiene rubber (NBR), acrylic rubber (ACM), fluororubber (FKM), epichlorohydrin rubber, and silicone rubber. Examples of resin include polycarbonate (PC), polyamide (PA), polyacetal (POM), modified polyphenylene ether (m-PPE), and polybutylene terephthalate (PBT). The setting block 82 is preferably made of a resin or hard rubber that is harder than general rubber. In the first embodiment, the setting block 82 is made of the hardest rubber, for example, ethylene propylene rubber (EPDM-S). The Shore A hardness of the setting block 82 is, for example, 90° or more. The Shore A hardness (durometer hardness, type A) is a value measured in accordance with JIS K6253-3:2012. Because the setting block 82 is made of hard rubber, it is less likely to elastically deform when the edge of the wall panel 40 is butted against it.

[0036] As an example, two setting blocks 82 are arranged at a distance from each other on the underside of the wall panel 40 inside the groove 72 of the cross member 46 (see FIG. 7). The setting blocks 82 are arranged at corners of the wall panel 40. Here, the corners of the wall panel 40 refer to areas within 25% of the edge of the wall panel 40 where the column 42 and the cross member 44 or cross member 46 intersect.

[0037] As shown in Figures 7 and 9(A) and (B), the cross member 44 has a groove 74 on the wall panel 40 side. That is, the groove 74 is open on the wall panel 40 side of the underside 44A (see Figure 9) of the cross member 44. A setting block 82 is provided inside the groove 74. The upper edge of the wall panel 40 inserted into the groove 74 abuts against the setting block 82. The groove 74 is an example of a second groove, and the setting block 82 is an example of a second setting block.

[0038] As an example, two setting blocks 82 are arranged spaced apart on the upper side of the wall panel 40 inside the groove 74 of the cross member 44 (see FIG. 7). The setting blocks 82 are arranged at the corners of the wall panel 40.

[0039] As described above, the edge of the wall panel 40 abuts against the setting block 82 arranged in the groove 72 of the lower cross member 46, and the edge of the wall panel 40 abuts against the setting block 82 arranged in the groove 74 of the upper cross member 44. In this way, the wall panel 40 is fixed to the pair of cross members 44, 46. The setting block 82 is made of a hard rubber material and is resistant to elastic deformation, so that the wall panel 40 can be firmly fixed to the pair of cross members 44, 46.

[0040] As shown in Figures 7 and 10, the pillar 42 has a groove 76 on the side of the wall panel 40. That is, the groove 76 opens on the wall panel 40 side of the side surface 42A (see Figure 8) of the pillar 42. A setting block 84 is provided inside the groove 76. The edge in the width direction of the wall panel 40 inserted into the groove 76 abuts against the setting block 84. The groove 76 is an example of a first groove, and the setting block 84 is an example of a first setting block.

[0041] The setting block 84 is, for example, a rectangular parallelepiped member, similar to the setting block 82. The setting block 84 is made of resin or rubber. The setting block 84 may be made of the same material as the setting block 82, or may be made of a different material. In the first embodiment, the setting block 84 is made of the same rubber material as the setting block 82.

[0042] Figure 10 shows the configuration of one of the pillars 42 in the width direction of the wall panel 40, but the configuration of the other pillar 42 in the width direction of the wall panel 40 is similar, so it is not shown in the illustration.

[0043] As an example, two setting blocks 84 are arranged vertically spaced apart on the side of the wall panel 40 inside the groove 76 of the column 42 (see FIG. 7). The setting blocks 84 are arranged at the corners of the wall panel 40. As a result, a total of four setting blocks 82 and 84 are arranged on each side of the corner of the wall panel 40 (see FIG. 7).

[0044] In the first embodiment, the edges of the wall panel 40 in the width direction are abutted against setting blocks 84 arranged inside the grooves 76 of the pair of pillars 42. This fixes the wall panel 40 to the pair of pillars 42. The setting blocks 84 are made of a hard rubber material and are not easily elastically deformed, so that the wall panel 40 can be firmly fixed to the pair of pillars 42.

[0045] Here, the cross member 46 will be described in more detail. As shown in FIG. 8 , the bottom surface portion 12 includes a floor panel 102 and a frame body 104. An end surface of the floor panel 102 is joined to the frame body 104. The cross member 46 is fixed to the frame body 104 by an L-shaped bracket 106. More specifically, one end of the bracket 106 is fixed to the frame body 104 by a fastener 108, and the other end of the bracket 106 is fixed to the cross member 46 by a fastener 110. An aluminum alloy square member 113 is disposed between the frame body 104 and the cross member 46 and inserted into a recess 112 of the cross member 46. Note that, although the aluminum alloy square member 113 is disposed in the recess 112 of the cross member 46 in the present disclosure, the square member 113 may be replaced with another member.

[0046] In FIG. 8, the frame 104 is secured to a base 126 using a bracket 120 and fasteners 122, 124, although the present disclosure is not limited to this configuration.

[0047] The cross member 46 is formed by bending a plurality of (for example, two) metal plates. The configuration of the cross member 46 can be changed. For example, the cross member 46 is formed by bending an aluminum alloy plate. The material of the cross member 46 can be changed, and the cross member 46 may be formed of a metal other than an aluminum alloy. As long as the cross member 46 has a groove 72 on the upper surface 46A, the shape of other parts can be changed. In order to stably support the wall panel 40 by the setting block 82 arranged in the groove 72, it is preferable that the rear side surface 72A of the groove 72 is flat. For example, the setting block 82 may be adhered to the rear side surface 72A of the groove 72 with an adhesive.

[0048] Additionally, caulking materials 130 and 132 are provided in the groove 72 of the cross member 46 closer to the opening than the setting block 82 to maintain airtightness between the wall panel 40 and the cross member 46. Caulking materials 130 and 132 are an example of a second caulking material. Caulking materials are used to fill gaps in exterior wall joints and other areas. Caulking materials are classified according to the process by which they harden into a rubber-like form, such as those that harden through a chemical reaction or those that dry. Examples of caulking materials 130 and 132 include moisture-curing materials such as silicone-based or polyurethane-based materials, dry-curing materials such as acrylic-based or butyl rubber-based materials, and mixed reaction-curing materials such as modified silicone-based or polysulfide-based materials. For example, a silicone-based moisture-curing material is used as the caulking material 130 and 132.

[0049] The caulking materials 130, 132 are filled between the wall panel 40 and the horizontal member 46 and allowed to harden, thereby providing the caulking materials 130, 132 between the wall panel 40 and the horizontal member 46. At this time, the caulking material 130 adheres to one surface of the wall panel 40, and a portion 130A of the caulking material 130 is inserted into the recess 142 of the horizontal member 46. Furthermore, the caulking material 132 adheres to the other surface of the wall panel 40, and a portion 132A of the caulking material 132 is inserted into the recess 142 of the horizontal member 46.

[0050] Next, the cross member 44 will be described in more detail. As shown in FIGS. 9(A) and 9(B), the cross member 44 is formed by bending multiple (e.g., two) metal plates. The configuration of the cross member 44 can be modified. For example, the cross member 44 is formed by bending an aluminum alloy plate. The material of the cross member 44 can be modified, and the cross member 44 may be formed of a metal other than aluminum alloy. The cross member 44 has a groove 74 on its lower surface 44A and a groove 154 on its upper surface 44B. The shape of other parts of the cross member 44 can be modified. In order to stably support the wall panel 40 using the setting block 82 arranged in the groove 74, the rear side surface 74A of the groove 74 is preferably flat. For example, the setting block 82 may be adhered to the rear side surface 74A of the groove 74 with an adhesive.

[0051] Additionally, caulking materials 150, 152 that maintain airtightness between the wall panel 40 and the horizontal member 44 are provided on the opening side of the setting block 82 in the groove portion 74 of the horizontal member 44. The caulking materials 150, 152 are an example of a second caulking material. The caulking materials 150, 152 are made of, for example, the same material as the caulking materials 130, 132. The caulking materials 150, 152 are provided between the wall panel 40 and the horizontal member 44 by filling the space between the wall panel 40 and the horizontal member 46 with the material that makes up the caulking materials 150, 152 and allowing it to harden. At this time, the caulking material 150 adheres to one surface of the wall panel 40, and a portion 150A of the caulking material 150 is inserted into the recess 160 of the horizontal member 44. Furthermore, the caulking material 152 adheres to the other surface of the wall panel 40 , and a portion 152 A of the caulking material 152 is inserted into the recess 162 of the cross member 44 .

[0052] Additionally, the edge of the transparent panel 48 is inserted into the groove 154 on the top surface 44B of the cross member 44. As described above, caulking materials 150, 152 that maintain airtightness between the wall panel 40 and the cross member 44 are provided on the opening side of the groove 154 on the top surface 44B of the cross member 44.

[0053] Next, the pillar 42 will be described in more detail. As shown in FIG. 10 , the pillar 42 is formed by bending a plurality of metal plates. The configuration of the pillar 42 can be modified. For example, the pillar 42 is formed by bending an aluminum alloy plate. The material of the pillar 42 can be modified, and the pillar 42 may be formed of a metal other than an aluminum alloy. The pillar 42 has a groove 76 on its side surface 42A. The shape of other parts of the pillar 42 can be modified. In order to stably support the side of the wall panel 40 in the width direction by the setting block 84 arranged in the groove 76, it is preferable that the rear surface 76A of the groove 76 is flat. For example, the setting block 84 may be adhered to the rear surface 76A of the groove 76 with an adhesive.

[0054] Additionally, caulking materials 172, 174 that maintain airtightness between the wall panel 40 and the column 42 are provided on the opening side of the setting block 84 in the groove portion 76 of the column 42. The configuration and attachment structure of the caulking materials 172, 174 are similar to those of the caulking materials 130, 132 of the cross member 46. The caulking materials 172, 174 are an example of a first caulking material.

[0055] Furthermore, the pair of pillars 42 on both sides of the width of the wall panel 40 have the same configuration, and the mounting structure of the wall panel 40 to the other pillar 42 is also the same as that shown in FIG.

[0056] In the first embodiment, the wall panel 40 is pre-assembled at the factory with a pair of pillars 42 and a setting block 84 interposed therebetween, and with a pair of cross members 44, 46 and a setting block 82 interposed therebetween.

[0059] (Action and effect) Next, the operation and effects of this embodiment will be described.

[0060] The box unit structure S2 includes an aluminum alloy wall panel 40 and a pair of columns 42 each having a groove 72 on the wall panel 40 side. The box unit structure S2 also includes a horizontal member 44 joined to the pair of columns 42 on both longitudinal sides and having a groove 74 on the wall panel 40 side, and a horizontal member 46 joined to the pair of columns 42 on both longitudinal sides and having a groove 72 on the wall panel 40 side. A setting block 84 is disposed inside the groove 76, and the wall panel 40 is fixed to the pair of columns 42 by abutting the edge of the wall panel 40 inserted into the groove 76 against the setting block 84. A setting block 82 is disposed in the grooves 72, 74, and the wall panel 40 is fixed to the pair of horizontal members 44, 46 by abutting the edge of the wall panel 40 inserted into the grooves 72, 76 against the setting block 82.

[0061] As a result, in a building 10 equipped with the box unit structure S2, the aluminum alloy wall panels 40 function as load-bearing walls and can resist compressive forces. In other words, by using the aluminum alloy wall panels 40 as structural materials for load-bearing walls, the building 10 equipped with the box unit structure S2 can achieve performance that can withstand live loads, wind pressure, and earthquakes. In addition, because the wall panels 40 function as structural materials for load-bearing walls, there is no need to provide diagonal members.

[0062] In the box unit structure S2, the setting blocks 82, 84 are made of resin or rubber. Therefore, in the box unit structure S2, rattle of the wall panel 40 relative to the pair of pillars 42 and the pair of cross members 44, 46 is suppressed.

[0063] In the box unit structure S2, a total of four setting blocks 82, 84 are arranged at each corner of the wall panel 40. Therefore, in the box unit structure S2, rattle of the wall panel 40 relative to the pair of columns 42 and the pair of cross members 44, 46 is suppressed.

[0064] In the box unit structure S2, caulking materials 170, 174 that maintain airtightness between the wall panel 40 and the column 42 are provided on the opening side of the setting block 84 in the groove 76 of the column 42. In addition, caulking materials 130, 132 that maintain airtightness between the wall panel 40 and the horizontal member 46 are provided on the opening side of the setting block 82 in the groove 72 of the horizontal member 46. In addition, caulking materials 150, 152 that maintain airtightness between the wall panel 40 and the horizontal member 44 are provided on the opening side of the setting block 82 in the groove 74 of the horizontal member 44. Therefore, in the box unit structure S2, airtightness is ensured between the wall panel 40 and the pair of columns 42 or the pair of horizontal members 44, 46 and the wall panel 40.

[0065] Second Embodiment Next, a building to which the box unit structure of the second embodiment is applied will be described. Note that the same components as those in the first embodiment described above will be assigned the same numbers and their description will be omitted.

[0066] FIG. 11 is a side view showing the configuration of the wall panel 40 and the setting blocks 202, 204 of a building to which the box unit structure S200 of the second embodiment is applied. As shown in FIG. 11, in the box unit structure S200, the setting blocks 202 and 204 are elongated members and are arranged in positions that contact the four sides of the wall panel 40. As an example, the setting blocks 202 and 204 are each formed as a long, narrow rectangular parallelepiped. A total of four setting blocks 202 and 204 are arranged along the four sides of one wall panel 40. The setting block 204 is an example of a first setting block, and the setting block 202 is an example of a second setting block. The other configurations are similar to those of the box unit structure S2 and the building 10 of the first embodiment.
