[0012] (Embodiment 1) 1. Overview The panel unit 100 of Embodiment 1 shown in Figures 1A and 1B comprises a sandwich panel 4 and an insulating edge material 5. The sandwich panel 4 has a metal outer shell 1 and an indoor outer shell 2 facing each other, and a plate-shaped core material 3 located between the outer shell 1 and the indoor outer shell 2, with the outer shell 1 including a side wall portion 11 along the side surface 30 of the core material 3. The insulating edge material 5 is attached to the side wall portion 11. The insulating edge material 5 has a plate-shaped edge material body 50 along the side wall portion 11 and an insulating material 51 covering one side of the edge material body 50 in the thickness direction.

[0013] Furthermore, the mounting structure of the panel unit 100 in Embodiment 1 shown in Figure 5 comprises the panel unit 100 and mounting members 8 and 9 for attaching the panel unit 100 to a part of the structural frame. The mounting members 8 and 9 have metal support members (specifically panel fixing plates 8a and 9a) and fasteners 8e and 9e. The support members 8a and 9a support the side wall portion 11 of the outdoor outer shell 1 and the indoor outer shell 2. The fasteners 8e and 9e fix the support members 8a and 9a to the side wall portion 11 with the insulating edge material 5 sandwiched between the support members 8a and 9a and the side wall portion 11.

[0014] Furthermore, the heat insulating edge material 5 of Embodiment 1 shown in Figures 1A and 1B is attached to the side wall portion 11 of the sandwich panel 4. The sandwich panel 4 has a metal outer shell 1 and an indoor outer shell 2 facing each other, and a plate-shaped core material 3 located between the outer shell 1 and the indoor outer shell 2, and the outer shell 1 includes a side wall portion 11 along the side surface 30 of the core material 3. The heat insulating edge material 5 comprises a plate-shaped edge material body 50 and a heat insulating material 51 that covers one side of the edge material body 50 in the thickness direction.

[0015] In the panel unit 100 of Embodiment 1 having the above configuration, the mounting structure of the panel unit 100, and the heat insulating material 5, when separate metal members (support members 8a, 9a, etc.) are installed so as to contact the side wall portion 11 of the outdoor outer skin 1 and the indoor outer skin 2 of the sandwich panel 4, the heat insulating material 5 can be sandwiched between this separate member and the side wall portion 11 of the outdoor outer skin 1, preventing direct contact. Thereby, in the panel unit 100 and the heat insulating material 5 of the present embodiment, heat transfer between the side wall portion 11 of the outdoor outer skin 1, the separate metal member, and the indoor outer skin 2 can be suppressed.

[0016] 2. Details Subsequently, the panel unit 100 of the present embodiment shown in FIGS. 1A to 5 will be described in more detail. The panel unit 100 includes a sandwich panel 4, a heat insulating material 5, and a connecting member 6. As shown in FIG. 3, the sandwich panel 4 has a rectangular plate shape. Hereinafter, one side in the thickness direction of the sandwich panel 4 is defined as the front side (outdoor side), the opposite side is defined as the rear side (indoor side), the longitudinal direction of the sandwich panel 4 is defined as the vertical direction, and the short side direction of the sandwich panel 4 is defined as the left-right direction, and each component will be described in detail.

[0017] 2-1. Sandwich panel As shown in FIGS. 1A and 3, the sandwich panel 4 has a metal outdoor outer skin 1 and an indoor outer skin 2 facing each other, and a plate-shaped core material 3 located between the outdoor outer skin 1 and the indoor outer skin 2, and the outdoor outer skin 1 includes a side wall portion 11 along the side surface 30 of the core material 3. The sandwich panel 4 is used, for example, as an outer wall of a building such as a building.

[0018] The sandwich panel 4, for example, has a length in the vertical direction of 0.5 to 6.0 m, a length (width) in the left-right direction of 0.2 to 1.5 m, and a length (thickness) in the front-rear direction of 50 to 150 mm.

[0019] The core material 3 has an overall rectangular plate shape. The overall plate shape is not limited to a single plate, but also includes arrangements of multiple components to form a single plate. In this embodiment, the core material 3 has thermal insulation properties. The core material 3 is made by arranging multiple blocks, each made of fibrous inorganic material such as rock wool or glass wool, solidified into blocks with a binder, etc., into a single rectangular plate shape. The core material 3 may also be made of foamed organic material such as urethane foam or phenolic foam, or it may be made of styrene board, urethane board, etc.

[0020] As shown in Figures 3, 4A, and 4B, the core material 3 has grooves 31 on its left and right sides 30. The grooves 31 are located approximately in the center of the left and right sides 30 of the core material 3 in the front-to-back direction, extending along the entire length in the vertical direction. A fire-resistant joint material (not shown) formed from a plate-like member such as gypsum board or calcium silicate board and a fibrous inorganic material such as alkali earth silicate blanket (biosoluble fiber) is inserted into the grooves 31. Note that, as shown in Figure 1A, the upper and lower sides 30 of the core material 3 do not have grooves 31 and are provided flat.

[0021] The outdoor outer shell 1 and the indoor outer shell 2 are each obtained by forming a metal sheet into a desired shape by rolling or pressing. The metal sheet has a thickness of, for example, 0.23 to 6.0 mm. The metal sheet is, but is not limited to, painted steel sheet, galvanized steel sheet, aluminum-zinc alloy plated steel sheet, Galvalume steel sheet (registered trademark), SGL (registered trademark) steel sheet, etc.

[0022] As shown in Figures 1A, 4A, and 4B, the outdoor outer shell 1 is a rectangular box shape with an opening towards the rear. The outdoor outer shell 1 has a rectangular plate-shaped main body portion 10 that covers the front (outdoor side) of the core material 3, and four side wall portions 11 that run along the four sides 30 of the core material 3. The four side wall portions 11 have a wall portion 11a that covers the upper side 30 (i.e., top surface) of the core material 3, and a wall portion 11b that covers the lower side 30 (i.e., bottom surface) of the core material 3. The four side wall portions 11 further have a left wall portion 11c that covers the portion of the left side 30 of the core material 3 that is in front of the recessed portion 31, and a right wall portion 11d that covers the portion of the right side 30 of the core material 3 that is in front of the recessed portion 31.

[0023] The upper wall portion 11a protrudes to the rear from the upper edge of the main body portion 10, the lower wall portion 11b protrudes to the rear from the lower edge of the main body portion 10, the left wall portion 11c protrudes to the rear from the left edge of the main body portion 10, and the right wall portion 11d protrudes to the rear from the right edge of the main body portion 10. Each of the four wall portions 11a, 11b, 11c, and 11d is approximately perpendicular to the main body portion 10. The upper and lower wall portions 11a and 11b are each rectangular flat plates. The left and right wall portions 11c and 11d each have a rectangular flat plate portion 110 and a rectangular plate-shaped projection portion 111 that protrudes approximately perpendicularly outward in the left and right directions from the rear end of the flat plate portion 110.

[0024] The indoor outer shell 2 has a rectangular plate-shaped main body portion 20 that covers the rear surface (indoor side) of the core material 3, a left side wall portion 21 that covers the portion of the left side surface 30 of the core material 3 that is behind the recessed portion 31, and a right side wall portion 22 that covers the portion of the right side surface 30 of the core material 3 that is behind the recessed portion 31. The left side wall portion 21 protrudes forward from the left edge of the main body portion 20, and the right side wall portion 22 protrudes forward from the right edge of the main body portion 20. The indoor outer shell 2 does not have portions that cover the upper side surface 30 or the lower side surface 30 of the core material 3.

[0025] Each of the left and right side wall portions 21 and 22 has curved portions 21a and 22a that curve outward in a U-shape in plan view from the left and right edges of the main body portion 20, and rectangular flat portions 21b and 22b that protrude forward from the front ends of the curved portions 21a and 22a.

[0026] Each of the outer shells 1 and 2 has its main body parts 10 and 20 bonded to the front and rear surfaces of the core material 3, integrating them with the core material 3. There is a gap between the upper wall portion 11a of the outdoor outer shell 1 and the upper side surface 30 of the core material 3, and there is also a gap between the lower wall portion 11b of the outdoor outer shell 1 and the lower side surface 30 of the core material 3.

[0027] The panel unit 100 further comprises packings 7 attached to four side wall portions 11. The packings 7 include four straight packings 70 and four L-shaped corner packings 71.

[0028] The straight packing 70 is attached to the upper surface of the upper wall portion 11a, the lower surface of the lower wall portion 11b, the left surface of the flat plate portion 110 of the left wall portion 11c, and the right surface of the flat plate portion 110 of the right wall portion 11d. The mounting positions of the packing 70 in the front-rear direction on the walls 11a, 11b, 11c, and 11d are the same for all of them. The packing 70 is hollow and cylindrical.

[0029] The corner packing 71 is attached to the corner portion formed by two adjacent wall portions 11a, 11b, 11c, and 11d. The corner packing 71 is an L-shaped solid block.

[0030] The four packings 70 and the four corner packings 71 are mounted in a rectangular frame shape when viewed from the front, surrounding the entire circumference of the sandwich panel 4. Each of the packings 70 and corner packings 71 is made of, for example, synthetic rubber.

[0031] 2-2. Insulation edging The heat-insulating edge material 5 is attached to the side wall portion 11 of the outdoor outer shell 1 and is configured to suppress heat transfer between the side wall portion 11 and other components (such as the connecting member 6).

[0032] As shown in Figure 1A, the insulating edge material 5 has an upper insulating edge material 5 attached to the upper side wall portion 11 (wall portion 11a) of the outdoor outer shell 1, and a lower insulating edge material 5 attached to the lower side wall portion 11 (wall portion 11b) of the outdoor outer shell 1. The upper and lower insulating edge materials 5 are identical in size and shape. The upper insulating edge material 5 will be described in detail below.

[0033] As shown in Figures 1B and 2, the thermal insulation edge material 5 comprises a plate-shaped edge material body 50 along the side wall portion 11 and a thermal insulation material 51 covering one side of the edge material body 50 in the thickness direction. The thermal insulation edge material 5 further comprises an adhesive member 52 attached to the other side of the edge material body 50 in the thickness direction.

[0034] The insulating edge material 5 has a longitudinal direction that aligns with the longitudinal direction (i.e., left-right direction) of the side wall portion 11 of the outdoor outer shell 1. The length of the insulating edge material 5 in the longitudinal direction is the same as or shorter than the length of the side wall portion 11 in the longitudinal direction. The insulating edge material 5 has a constant cross-sectional structure perpendicular to the longitudinal direction throughout its entire length. The edge material body 50, the insulating material 51, and the adhesive member 52 have the same length in the longitudinal direction.

[0035] The edge material body 50 is made of metal. The edge material body 50 is formed, for example, by bending a plated steel sheet with a thickness of 0.8 to 1.2 mm. The edge material body 50 is formed, for example, from the same material as the metal sheets that make up the outer shells 1 and 2.

[0036] The edge material body 50 has a main body portion 500 that follows the side wall portion 11, and a projection portion 501 that protrudes from the main body portion 500 and is in contact with the front end surface 112 of the side wall portion 11 that faces inward. The edge material body 50 further has a second projection portion 502 that protrudes from the outdoor end of the main body portion 500 toward the opposite side from the projection portion 501.

[0037] In this embodiment, the main body portion 500 is a rectangular plate shape having a longitudinal direction parallel to the left-right direction. The protruding portion 501 protrudes from one end of the main body portion 500 in the width direction (specifically, the end on the indoor side), and the second protruding portion 502 protrudes from the other end of the main body portion 500 in the width direction (specifically, the end on the outdoor side). Each of the protruding portions 501 and 502 protrudes perpendicular to the main body portion 500.

[0038] The thermal insulation material 51 is attached to the edge material body 50 on the side facing away from the side wall portion 11 (see Figure 1A). The thermal insulation material 51 has a portion 510 that covers the main body portion 500, a portion 511 that covers the protruding portion 501, and an elastically deformable extendable portion 512 that extends beyond the protruding portion 501. The thermal insulation material 51 further has a portion 513 that covers the second protruding portion 502. The portions 513, 510, 511, and extendable portion 512 are continuous in this order.

[0039] The thermal insulation material 51 is a thermally insulating material such as ethylene propylene diene rubber (EPDM). In this embodiment, the thermal insulation material 51 is in sheet form. The thickness of the thermal insulation material 51 is, for example, 2 mm. The thermal insulation material 51 is attached to the main body portion 500, the protruding portion 501, and the second protruding portion 502 of the edge material body 50 using double-sided tape or the like.

[0040] As shown in Figure 1A, the length of the extended portion 512 is set such that, with the insulating edge material 5 attached to the side wall portion 11 of the outer shell 1, at least the tip of the extended portion 512 contacts the side surface 30 of the core material 3. Since the extended portion 512 is elastically deformable, it can be made to conform to the side surface 30 of the core material 3.

[0041] The adhesive member 52 is a member used to bond the edge material body 50 to the side wall portion 11 of the outdoor outer shell 1. The adhesive member 52 is, for example, a butyl tape with a thickness of 2 mm. The adhesive member 52 is attached to the main body portion 500 of the edge material body 50. As shown in Figures 1B and 2, the protruding portion 501 of the edge material body 50 protrudes in a direction away from the main body portion 500 than the adhesive member 52.

[0042] As shown in Figure 1A, the adhesive member 52 is bonded to the side wall portion 11 of the outer shell 1 with the tip of the protruding portion 501 of the edge material body 50 touching the tip surface 112 of the side wall portion 11 of the outer shell 1 that faces indoors. The adhesive member 52, the main body portion 500 of the edge material body 50, and the portion 510 of the insulation material 51 are laminated on the side wall portion 11 in this order. The insulation edge material 5 is attached to the side wall portion 11 by the adhesive force of the adhesive member 52.

[0043] When the insulating edge material 5 is attached to the side wall portion 11 of the outdoor outer shell 1, the second protrusion 502 of the insulating edge material 5 is positioned approximately the same in the front-to-back direction with respect to the protrusions 111 of the left and right side wall portions 11 of the outdoor outer shell 1 (see Figures 4A and 4B). The four straight packings 70 are attached by pressing them against the second protrusions 502 of the upper and lower insulating edge materials 5 and the protrusions 111 of the left and right side wall portions 11 of the outdoor outer shell 1, making it easier to align their attachment positions in the front-to-back direction.

[0044] 2-3. Connecting Members The connecting member 6 is a metal member that connects the side wall portion 11 of the outdoor outer shell 1 and the indoor outer shell 2. In this embodiment, the connecting member 6 is composed of a part of the mounting members 8 and 9 (specifically, panel fixing plates 8a and 9a) for attaching the sandwich panel 4 to a part of the structural frame.

[0045] The mounting members 8 and 9 include a lower mounting member 8 fixed to the lower end of the rear surface of the sandwich panel 4, and an upper mounting member 9 fixed to the upper end of the rear surface of the sandwich panel 4. As shown in Figure 5, the mounting members 8 and 9 are used to attach the horizontal members 101 of the structural frame.

[0046] As shown in Figures 1A and 3, the lower mounting member 8 includes three L-shaped panel fixing plates 8a in side view that are fixed to the lower end of the rear surface of the sandwich panel 4, two roughly Z-shaped mounting plates 8b in side view that are attached to the two panel fixing plates 8a at both the left and right ends, and bolts 8c that fix each mounting plate 8b to the corresponding panel fixing plate 8a. The lower mounting member 8 further includes fasteners 8d and 8e, such as self-drilling screws, that fix the panel fixing plates 8a to the sandwich panel 4.

[0047] Each of the three panel fixing plates 8a and the two mounting plates 8b is made of metal, for example, formed by bending a metal sheet. The metal sheets forming the panel fixing plates 8a and mounting plates 8b are thicker than the metal sheets forming the outer shells 1 and 2. The bolts 8c are bolts that can be fastened from one side.

[0048] The three panel fixing plates 8a are arranged at intervals in the left-right direction. Each of the three panel fixing plates 8a has a vertical piece 80 parallel to the main body 20 of the indoor outer shell 2, and a horizontal piece 81 extending forward from the lower end of the vertical piece 80 and parallel to the lower side wall 11 (wall 11b) of the outdoor outer shell 1. The vertical piece 80 is fixed to the lower end of the main body 20 of the indoor outer shell 2 with a fastener 8d, and the front end of the horizontal piece 81 is fixed to the lower side wall 11 (wall 11b) of the outdoor outer shell 1 with a fastener 8e.

[0049] The upper part of the mounting plate 8b is fixed with bolts 8c to the upper part of the vertical pieces 80 of each of the two panel fixing plates 8a at both the left and right ends, and an insertion groove 82 is formed between the lower part of the vertical piece 80 and the lower part of the mounting plate 8b into which the vertical plate portion 102 of the horizontal member 101 can be inserted. The width of the insertion groove 82 can be adjusted by how tightly the bolts 8c are screwed. By screwing the bolts 8c all the way in, the mounting plate 8b can be pressed against the vertical plate portion 102.

[0050] The upper mounting member 9 includes two L-shaped panel fixing plates 9a fixed to the upper end of the rear surface of the sandwich panel 4, two rectangular plate-shaped mounting plates 9b attached to each of the two panel fixing plates 9a, and bolts 9c for fixing each mounting plate 9b to the corresponding panel fixing plate 9a. The upper mounting member 9 further includes fasteners 9d and 9e, such as self-drilling screws, for fixing the panel fixing plates 9a to the sandwich panel 4.

[0051] Each of the two panel fixing plates 9a and the two mounting plates 9b is made of metal. Each of the two panel fixing plates 9a is formed, for example, by bending a metal plate. The metal plates forming the panel fixing plates 9a and the mounting plates 9b are thicker than the metal plates forming the outer shells 1 and 2. The bolts 9c are bolts that can be fastened from one side.

[0052] The two panel fixing plates 9a are spaced apart in the left-right direction. The left-right positions of the two panel fixing plates 9a are the same as the two panel fixing plates 8a at both the left and right ends. Each of the two panel fixing plates 9a has a vertical piece 90 parallel to the main body 20 of the indoor outer shell 2, and a horizontal piece 91 extending forward from the upper end of the vertical piece 90 and parallel to the upper side wall 11 (wall 11a) of the outdoor outer shell 1. The vertical piece 90 is fixed to the upper end of the main body 20 of the indoor outer shell 2 with a fastener 9d, and the front end of the horizontal piece 91 is fixed to the upper side wall 11 (wall 11a) of the outdoor outer shell 1 with a fastener 9e. The lower part of the mounting plate 9b is fixed to the vertical piece 90 of each of the two panel fixing plates 9a with a bolt 9c.

[0053] In this embodiment, each of the three panel fixing plates 8a and the two panel fixing plates 9a constitutes a metal connecting member 6 that connects the side wall portion 11 of the outdoor outer shell 1 and the indoor outer shell 2. The attachment members 8 and 9 to the sandwich panel 4 are performed with the heat insulating edge material 5 attached to the upper and lower side wall portions 11 of the outdoor outer shell 1.

[0054] As shown in Figure 5, the panel unit 100 is attached to the horizontal member 101 by inserting the vertical plate portion 102 of the horizontal member 101 into the insertion groove 82 between the two mounting plates 8b and the two panel fixing plates 8a opposite to them, and then hooking the two mounting plates 8b onto the vertical plate portion 102. The panel unit 100 is supported by the horizontal member 101 so that it can slide in the left-right direction.

[0055] 2-4. Panel Unit Mounting Structure As shown in Figure 5, the panel unit 100 of this embodiment described above is attached to the horizontal member 101 of the structural frame. The mounting structure of the panel unit 100 comprises the panel unit 100 described above and mounting members 8 and 9.

[0056] The horizontal member 101 constitutes a part of the structural frame, and in this embodiment, it is an L-shaped angle member in side view. The horizontal member 101 is made of steel. The horizontal member 101 has a vertical plate portion 102 and a horizontal plate portion 103 extending to the rear from the lower end of the vertical plate portion 102. The thickness (length in the front-to-back direction) of the vertical plate portion 102 is, for example, less than 10 mm, and preferably about 6 to 9 mm. The horizontal plate portion 103 of the horizontal member 101 is fixed to the base 104 that constitutes the floor or ceiling of the building. The horizontal member 101 may be fixed to a beam, or it may be fixed by spanning across multiple columns.

[0057] Of the vertical plate portion 102 of the horizontal member 101, a support member (not shown) in a side view, which supports the panel fixing plate 8a located in the center in the left-right direction of the lower mounting member 8 of the sandwich panel 4, is fixed to the front surface of the portion by welding or the like.

[0058] Two panel units 100 are attached to the horizontal member 101, arranged vertically. The lower panel unit 100 is fixed to the vertical plate portion 102 of the horizontal member 101 by welding or other appropriate means, using two mounting plates 9b of the upper mounting member 9.

[0059] The upper panel unit 100 is secured by tightening the two bolts 8c of the lower mounting member 8, which causes the two mounting plates 8b to press against the vertical plate portion 102 of the horizontal member 101. The mounting plate 9b of the lower panel unit 100 is sandwiched between the vertical pieces 80 of the two panel fixing plates 8a at both ends of the upper panel unit 100 and the vertical plate portion 102 of the horizontal member 101.

[0060] The left and right center panel fixing plates 8a are placed on support members fixed to the vertical plate portions 102 of the horizontal members 101, and the weight of the panel unit 100 is supported by the support members. The left and right center panel fixing plates 8a are not fixed to the support members by welding or the like.

[0061] The packing 70 at the lower end of the upper panel unit 100 and the packing 70 at the upper end of the lower panel unit 100 are in close contact. A backing material 105 is placed on the outdoor side of the two packings 70, and a sealing material 106 is filled on the outdoor side of the backing material 105.

[0062] Furthermore, the lower end of the lower panel unit 100 and the upper end of the upper panel unit 100 are attached to the other horizontal members 101 in the same manner.

[0063] 3. Effects In the panel unit 100 of this embodiment described above, the heat insulating edge material 5 attached to the side wall portion 11 of the outdoor outer shell 1 of the sandwich panel 4 prevents direct contact between the side wall portion 11 of the outdoor outer shell 1 and the connecting member 6. Therefore, in the panel unit 100 of this embodiment, heat transfer between the outdoor outer shell 1, the connecting member 6 and the indoor outer shell 2 can be suppressed. As a result, in the panel unit 100 of this embodiment, even if the outdoor outer shell 1 is cooled by the outside temperature, condensation on the surface of the connecting member 6 and the indoor outer shell 2 can be suppressed.

[0064] Furthermore, in the panel unit 100 of this embodiment, condensation is less likely to occur on the connecting member 6, thus suppressing corrosion of the fasteners 8e and 9e that fix the connecting member 6 to the outer shell 1 and 2. Therefore, in the panel unit 100 of this embodiment, it is easier to maintain the state in which the connecting member 6 is fixed to the outer shell 1 and 2, and a decrease in the fixing force of the sandwich panel 4 to the structural frame can be suppressed.

[0065] Furthermore, in the panel unit 100 of this embodiment, by attaching the heat insulating edge material 5 to the side wall portion 11 of the outdoor outer shell 1, the thickness of the fixing surface for the fasteners 8e and 9e that fix the connecting members 6 (support members 8a and 8b) can be increased, thereby improving the mounting strength of the connecting members 6.

[0066] Furthermore, in the panel unit 100 of this embodiment, the protruding portion 501 of the edge material body 50 of the insulating edge material 5 can be brought into contact with the front end surface 112 of the side wall portion 11 of the outdoor outer shell 1 that faces the indoor side, making it easier to stabilize the mounting position of the insulating edge material 5 in the front-rear direction. Therefore, in the panel unit 100 of this embodiment, it is easier to keep the front-rear position of the second protruding portion 502 of the insulating edge material 5 constant, and the front-rear mounting position of the packing 70, which is positioned to contact the second protruding portion 502, is also easier to stabilize.

[0067] Furthermore, in the panel unit 100 of this embodiment, the insulating material 51 of the insulating edge material 5 has an elastically deformable stretchable portion 512 that contacts the side surface 30 of the core material 3. Therefore, in the panel unit 100 of this embodiment, even if moisture flows between the side wall portion 11 of the outdoor outer shell 1 and the side surface 30 of the core material 3, the stretchable portion 512 can prevent this moisture from flowing to the connecting member 6 and the indoor outer shell 2.

[0068] Furthermore, in the panel unit 100 of this embodiment, the heat insulating material 51 has a portion 513 that covers the second protrusion 502 of the edge material body 50, thus preventing direct contact between the second protrusion 502 and the connecting member 6.

[0069] 4. Variations Modifications of the panel unit 100 of this embodiment described above will now be explained. Note that the following modifications can be combined as appropriate.

[0070] The sandwich panel 4 is not limited to the structure shown in Figure 1A, etc. The sandwich panel 4 has a metal outer shell 1 and an indoor outer shell 2 facing each other, and a plate-shaped core material 3 located between the outer shell 1 and the indoor outer shell 2, and the outer shell 1 may include a side wall portion 11 along the side surface 30 of the core material 3. For example, the indoor outer shell 2 may further have a side wall portion located along the side surface 30 of the core material 3 and away from the side wall portion 11 of the outer shell 1.

[0071] Furthermore, the insulating edge material 5 only needs to be attached to the side wall portion 11 of the outdoor outer shell 1, and is not limited to the upper and lower side wall portions 11 of the outdoor outer shell 1, but may be attached to only one of the upper and lower side wall portions 11, or to the left and right side wall portions 11.

[0072] The panel unit 100 does not necessarily have to be equipped with metal connecting members 6 (panel fixing plates 8a, 9a). For example, the side wall portion 11 of the outdoor outer shell 1 and the indoor outer shell 2 of the panel unit 100 may be supported by L-shaped metal support members fixed to the structural frame. In this case as well, the insulating edge material 5 can prevent direct contact between the metal support member and the side wall portion 11.

[0073] Furthermore, the connecting member 6 only needs to have the function of connecting the side wall portion 11 of the outdoor outer shell 1 and the indoor outer shell 2, and does not need to have the function of supporting the weight of the sandwich panel 4. In other words, the connecting member 6 does not have to be composed of a part of the mounting members 8 and 9 (panel fixing plates 8a and 9a).

[0074] Furthermore, the insulating edge material 5 does not necessarily have to have an adhesive member 52 attached to the edge material body 50. The insulating edge material 5 may be attached to the side wall portion 11 by adhesive, or it may be attached to the side wall portion 11 solely by the fixing force of the fasteners 8e and 9e that fix the connecting member 6.

[0075] Furthermore, the edge material body 50 may have only the body portion 500 among the body portion 500, the protruding portion 501, and the second protruding portion 502, or it may have only the body portion 500 and either the protruding portion 501 or the second protruding portion 502.

[0076] Furthermore, the insulation material 51 only needs to have a portion 510 that covers the main body portion 500 of the edge material body 50, and does not need to have a portion 513 that covers the second protrusion 502, nor does it need to have a portion 511 that covers the protrusion 501, nor does it need to have an extended portion 512.

[0077] The insulating edge material 5 only needs to consist of a plate-shaped edge material body 50 and an insulating material 51 that covers one side of the edge material body 50 in the thickness direction, and is not limited to the structure shown in Figure 1A, etc. For example, the insulating material 51 may be provided so as to cover the side of the edge material body 50 that faces the side wall portion 11. In this case as well, the insulating material 51 can suppress heat transfer between the side wall portion 11 and the connecting member 6.

[0078] Furthermore, the mounting structure of the panel unit 100 is not limited to the structure shown in Figure 5. The mounting members 8 and 9 only need to have at least support members (panel fixing plates 8a and 9a) and fasteners 8e and 9e, and do not need to have mounting plates 8b and 9b, bolts 8c and 9c, and fasteners 8d and 9d. For example, the panel fixing plates 8a and 9a may be fixed to the main body 20 of the indoor outer shell 2 by welding. Also, the panel fixing plates 8a and 9a may be attached to a part of the structural frame by other means without using mounting plates 8b and 9b. In addition, the mounting destination of the mounting members 8 and 9 is not limited to the horizontal member 101, and can be any part of the structural frame.

[0079] The edge material body 50 is not limited to metal; it may also be made of other hard materials.

[0080] The insulating edge material 5 is not limited to being the same length as the side wall portion 11, but may be composed of multiple parts positioned at intervals. In this case, each of the multiple parts is attached at least to the fixing points of the connecting member 6 (i.e., multiple panel fixing plates 8a, 9a) on the side wall portion 11.

[0081] (Embodiment 2) 1.Details Next, the panel unit 100 of Embodiment 2 shown in Figures 6 and 7 will be described. Since the basic configuration of the panel unit 100 of Embodiment 2 is the same as that of Embodiment 1, explanations that overlap with those of Embodiment 1 will be omitted and indicated with the same reference numerals in the figures.

[0082] In the panel unit 100 of this embodiment, the protruding portion 501 of the edge material body 50 of the heat insulating edge material 5 has a length that allows it to be inserted into a groove 32 provided on the side surface 30 of the core material 3. The heat insulating material 51 of the heat insulating edge material 5 has a portion 511 that covers the protruding portion 501 of the edge material body 50, but does not have an extended portion 512.

[0083] A groove 32 is provided on the side surface 30 of the core material 3. The groove 32 extends in a straight line along the tip surface 112 of the side wall portion 11. The groove 32 is formed by excavating a part of the side surface 30 of the core material 3, for example, with a drill.

[0084] In the panel unit 100 of Embodiment 2 described above, the heat insulating edge material 5 attached to the side wall portion 11 of the outdoor outer shell 1 of the sandwich panel 4 prevents direct contact between the side wall portion 11 of the outdoor outer shell 1 and the connecting member 6. Therefore, in the panel unit 100 of this embodiment, heat transfer between the outdoor outer shell 1, the connecting member 6 and the indoor outer shell 2 can be suppressed.

[0085] Furthermore, in the panel unit 100 of Embodiment 2, with the heat insulating edge material 5 attached to the side wall portion 11, the tip of the protruding portion 501 of the edge material body 50 of the heat insulating edge material 5 can be inserted into the groove 32 of the side surface 30 of the core material 3. As a result, in the panel unit 100 of Embodiment 2, even if moisture flows between the side wall portion 11 of the outdoor outer shell 1 and the side surface 30 of the core material 3, the protruding portion 501 can prevent this moisture from flowing to the connecting member 6 and the indoor outer shell 2.

[0086] Furthermore, the panel unit 100 of Embodiment 2 described above can be appropriately combined with modified versions of the panel unit 100 of Embodiment 1 described above.

[0087] (summary) As described above in Embodiments 1 and 2 and their modifications, the panel unit 100 of the first embodiment has the following configuration.

[0088] In other words, the panel unit 100 of the first embodiment comprises a sandwich panel 4 and an insulating edge material 5.

[0089] In the first embodiment of the panel unit 100 having the above configuration, when a separate metal member (support member 8a, 9a, etc.) is installed so as to come into contact with the side wall portion 11 of the outdoor outer shell 1 of the sandwich panel 4 and the indoor outer shell 2, the insulating edge material 5 can be sandwiched between this separate member and the side wall portion 11 of the outdoor outer shell 1, thereby preventing direct contact. As a result, in the first embodiment of the panel unit 100, heat transfer between the side wall portion 11 of the outdoor outer shell 1, the separate metal member, and the indoor outer shell 2 can be suppressed. Furthermore, in the first embodiment of the panel unit 100, when the separate metal member is fixed to the side wall portion 11 via the insulating edge material 5 using fasteners 8e, 9e such as screws, even if the side wall portion 11 is thin, the insulating edge material 5 can increase the thickness of the fixing surface of the fasteners 8e, 9e, thereby improving the mounting strength of the separate metal member.

[0090] Furthermore, as described above in embodiments 1 and 2 and their modifications, the panel unit 100 of the second embodiment additionally includes the following configuration in addition to the configuration of the first embodiment.

[0091] In other words, the panel unit 100 of the second embodiment further comprises a metal connecting member 6 that connects the side wall portion 11 of the outdoor outer shell 1 and the indoor outer shell 2. The connecting member 6 is attached to the side wall portion 11 with an insulating edge material 5 sandwiched between it and the side wall portion 11.

[0092] In the second embodiment of the panel unit 100 having the above configuration, an insulating material 51 can be sandwiched between the metal connecting member 6 and the side wall portion 11 of the outdoor outer shell 1, thereby suppressing heat transfer between the side wall portion 11 of the outdoor outer shell 1, the connecting member 6, and the indoor outer shell 2.

[0093] Furthermore, as described above in embodiments 1 and 2 and their modifications, the panel unit 100 of the third embodiment additionally includes the following configuration in addition to the configuration of the first or second embodiment.

[0094] In other words, in the panel unit 100 of the third embodiment, the heat insulating edge material 5 further has an adhesive member 52 attached to the other side in the thickness direction of the edge material body 50.

[0095] In the third embodiment of the panel unit 100 having the above configuration, the heat insulating edge material 5 can be attached to the side wall portion 11 of the outdoor outer shell 1 by the adhesive force of the adhesive member 52, making it easy to attach the heat insulating edge material 5 to the side wall portion 11.

[0096] Furthermore, as described above in embodiments 1 and 2 and their variations, the panel unit 100 of the fourth embodiment additionally includes the following configuration in addition to the configuration of any one of the first to third embodiments.

[0097] In other words, in the panel unit 100 of the fourth embodiment, the edge material body 50 has a main body portion 500 that follows the side wall portion 11, and a protruding portion 501 that protrudes from the main body portion 500 and corresponds to the front end surface 112 of the side wall portion 11 that faces indoors.

[0098] In the fourth embodiment of the panel unit 100 having the above configuration, the heat insulating edge material 5 has a protruding portion 501 that contacts the front end surface 112 of the side wall portion 11, which makes it easier to stabilize the mounting position of the heat insulating edge material 5.

[0099] Furthermore, as described above in embodiments 1 and 2 and their variations, the panel unit 100 of the fifth embodiment additionally includes the following configuration in addition to the configuration of the fourth embodiment.

[0100] In other words, in the fifth embodiment of the panel unit 100, the edge material body 50 further has a second projection 502 that protrudes from the outdoor end of the main body 500 toward the opposite side from the projection 501.

[0101] In the fifth embodiment of the panel unit 100 having the above configuration, the packing 70 attached to the side wall portion 11 can be brought into contact with the second protrusion 502, making it easier to stabilize the mounting position of the packing 70 on the side wall portion 11.

[0102] Furthermore, as described above in Embodiment 1 and its modified form, the panel unit 100 of the sixth embodiment additionally includes the following configuration in addition to the configuration of the fourth or fifth embodiment.

[0103] In other words, in the panel unit 100 of the sixth embodiment, the thermal insulation material 51 has a portion 510 that covers the main body portion 500, a portion 511 that covers the protruding portion 501, and an elastically deformable stretchable portion 512 that extends beyond the protruding portion 501.

[0104] In the sixth embodiment of the panel unit 100 having the above configuration, the extended portion 512 of the insulating material 51 of the insulating edge material 5 attached to the side wall portion 11 of the outdoor outer shell 1 can partition the gap between the side surface 30 of the core material 3 and the side wall portion 11 from the space on the indoor side of this gap. Therefore, in the sixth embodiment of the panel unit 100, the extended portion 512 can suppress moisture that has flowed between the side wall portion 11 and the side surface 30 of the core material 3 from flowing to the separate metal members (support members 8a, 9a, etc.) and the indoor outer shell 2.

[0105] Furthermore, as in Embodiments 1 and 2 and their modified forms, the mounting structure of the panel unit 100 in the seventh embodiment has the following configuration.

[0106] In other words, the mounting structure of the panel unit 100 in the seventh embodiment comprises a panel unit 100 of any one of the first to sixth embodiments, and mounting members 8 and 9 for attaching the panel unit 100 to a part of the structural frame. The mounting members 8 and 9 have metal support members (specifically panel fixing plates 8a and 9a) and fasteners 8e and 9e. The support members 8a and 9a support the side wall portion 11 of the outdoor outer shell 1 and the indoor outer shell 2. The fasteners 8e and 9e fix the support members 8a and 9a to the side wall portion 11 with an insulating edge material 5 sandwiched between the support members 8a and 9a and the side wall portion 11.

[0107] In the mounting structure of the panel unit 100 according to the seventh embodiment, the heat insulating edge material 5 can be sandwiched between the metal support members 8a, 9a and the side wall portion 11 of the outdoor outer shell 1, thereby preventing direct contact. As a result, in the mounting structure of the panel unit 100 according to the seventh embodiment, heat transfer between the side wall portion 11 of the outdoor outer shell 1 and the metal support members 8a, 9a and the indoor outer shell 2 can be suppressed. In addition, in the mounting structure of the panel unit 100 according to the seventh embodiment, condensation is less likely to occur on the surface of the metal support members 8a, 9a, thus suppressing corrosion of the fasteners 8e, 9e and preventing a decrease in the fixing force of the fasteners 8e, 9e.

[0108] Furthermore, as in Embodiments 1 and 2 and their modified forms, the heat insulating edge material 5 of the eighth embodiment has the following configuration.

[0109] In other words, the heat insulating edge material 5 of the eighth embodiment is attached to the side wall portion 11 of the sandwich panel 4.
