DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, embodiments of a composite exterior wall panel and a building according to the present invention will be described with reference to the drawings. In each drawing, the same components are designated by the same reference numerals.

[0017] Fig. 1 is a diagram showing a composite exterior wall panel 1 as one embodiment of the composite exterior wall panel according to the present invention. Fig. 1 shows the composite exterior wall panel 1 attached to the structural frame 501 of a building 500. As shown in Fig. 1, the composite exterior wall panel 1 of this embodiment is attached to the structural frame 501 of the building 500, and can be connected to another composite exterior wall panel 1 or a single exterior wall panel material to form an external finishing layer of the exterior wall of the building 500. Note that for ease of explanation, Fig. 1 shows only one composite exterior wall panel 1 attached to the structural frame 501 of the building 500.

[0018] First, an overview of the building 500 of this embodiment will be described. The building 500 of this embodiment is, for example, a two-story detached house with a steel-framed framework. Such a building 500 includes, for example, a foundation structure such as a reinforced concrete continuous footing supported on the ground, and a superstructure having a structural framework 501 composed of framework members such as pillar members and beam members and supported by the foundation structure. The framework members constituting the structural framework 501 may be pre-standardized members that are manufactured in a factory and then transported to a construction site and assembled. The building 500 may also be a wooden house built using a so-called conventional construction method. The building 500 is not limited to a two-story building, but may have one or three or more floors. Furthermore, the building 500 is not limited to a detached house, but may be, for example, an apartment building.

[0019] More specifically, the superstructure of the building 500 of this embodiment includes the above-mentioned structural body 501, exterior walls, a floor, and a roof.

[0020] The exterior wall is a wall that separates the indoor space from the outdoor space of the building 500. The exterior wall of the building 500 of this embodiment has an exterior finishing layer formed by connecting exterior wall panel materials around the outer periphery of a structural body 501. The exterior wall of the building 500 of this embodiment is configured to include a composite exterior wall panel 1 having a first exterior wall panel material 20 and a second exterior wall panel material 40. Details of the composite exterior wall panel 1 will be described later.

[0021] The exterior wall of this embodiment also includes an insulating layer formed by connecting foamed resin insulating panels, such as phenolic foam, along the interior surface of the exterior finishing layer. However, the insulating material may also be a fiber-based material such as rock wool.

[0022] Furthermore, the exterior wall of this embodiment has an internal finishing layer made of interior materials that are made up of gypsum boards and finishing materials such as wall paper attached to the surface of the gypsum boards. However, the configuration of the interior materials is not limited to the configuration of this embodiment.

[0023] The floor in this embodiment includes a floor slab material. The floor slab material is installed between the beams of the structural frame 501 and is directly or indirectly supported by the beams. For example, an aerated concrete (ALC) panel can be used as the floor slab material, but other materials such as folded plates, extruded cement boards, and wood panels may also be used. In addition to the floor slab material, the floor may also include, for example, a ceiling interior material that forms the ceiling surface of the lower floor and is attached directly or indirectly to the floor slab material, and a floor interior material such as flooring that forms the floor surface of the upper floor and is layered on the floor slab material.

[0024] The roof of the building 500 in this embodiment is a flat roof. ALC panels can be used for the roof floor slab materials that make up the flat roof, but the materials are not limited to ALC panels. The roof floor slab materials are waterproofed by being covered with a waterproof sheet made of polyvinyl chloride resin, for example. The roof of the building 500 is not limited to a flat roof, and may also be a sloped roof using roof exterior materials such as slate.

[0025] Next, the composite exterior wall panel 1 will be described in detail.

[0026] As described above, the composite exterior wall panel 1 of this embodiment is attached to the structural frame 501 of the building 500, and another composite exterior wall panel 1 or a single exterior wall panel material can be connected to form the exterior finishing layer of the exterior wall of the building 500. Specifically, the structural frame 501 of the building 500 of this embodiment has upper beams 501a and lower beams 501b extending horizontally at different positions in the vertical direction. In the building 500 of this embodiment, the composite exterior wall panel 1 is attached to the upper beams 501a and lower beams 501b of the structural frame 501.

[0027] Hereinafter, for the sake of convenience, the thickness direction of the composite exterior wall panel 1 will be simply referred to as the "thickness direction A." Furthermore, the outdoor side of the composite exterior wall panel 1 in the thickness direction A, based on the state in which the composite exterior wall panel 1 is attached to the structural body 501, will be simply referred to as the "outdoor side." Furthermore, the indoor side of the thickness direction A of the composite exterior wall panel 1, based on the state in which the composite exterior wall panel 1 is attached to the structural body 501, will be simply referred to as the "indoor side."

[0028] 1 is a front view of a composite exterior wall panel 1 viewed from the outdoor side. As shown in FIG. 1, the composite exterior wall panel 1 includes a first exterior wall panel material 20, a second exterior wall panel material 40, and a connector 100.

[0029] 1, the first exterior wall panel material 20 and the second exterior wall panel material 40 are rectangular. Specifically, the first exterior wall panel material 20 and the second exterior wall panel material 40 have a rectangular outer shape when viewed from the thickness direction A.

[0030] Although details will be described later, the connector 100 connects the first exterior wall panel material 20 and the second exterior wall panel material 40 in a state in which the first exterior wall panel material 20 and the second exterior wall panel material 40 are arranged side by side so that the end faces 24, 44 of the first exterior wall panel material 20 and the second exterior wall panel material 40 are adjacent to each other. For convenience of explanation, in this embodiment, the parallel direction parallel to the end face 24 of the first exterior wall panel material 20 and the end face 44 of the second exterior wall panel material 40, which are adjacent to each other, when viewed from the thickness direction A will be referred to as the "horizontal direction B," and the perpendicular direction perpendicular to the horizontal direction B as the parallel direction will be referred to as the "vertical direction C."

[0031] The first exterior wall panel material 20 and the second exterior wall panel material 40 are connected to the connector 100 and arranged side by side in the vertical direction C. For ease of explanation, when the composite exterior wall panel 1 is viewed from the outdoors in a state where the vertical direction C coincides with the vertical direction and the first exterior wall panel material 20 is positioned vertically upper and the second exterior wall panel material 40 is positioned vertically lower (i.e., the state shown in FIG. 1 ), one side in the vertical direction C as the vertically upper side will be described as the “upper side of the vertical direction C” or simply the “upper side,” the other side in the vertical direction C as the vertically lower side will be described as the “lower side of the vertical direction C” or simply the “lower side,” one side in the horizontal direction B as the horizontally left side will be described as the “left side of the horizontal direction B” or simply the “left side,” and the other side in the horizontal direction B as the horizontally right side will be described as the “right side of the horizontal direction B” or simply the “right side.”

[0032] The first exterior wall panel material 20 of this embodiment has two surfaces 22 perpendicular to the thickness direction A and four end surfaces 24 parallel to the thickness direction A. When viewed from the thickness direction A, these four end surfaces 24 form the sides of a rectangle. For ease of explanation, of the two surfaces 22 of the first exterior wall panel material 20 perpendicular to the thickness direction A, the outdoor-side surface 22 will be referred to as the "outdoor-side surface 22a of the first exterior wall panel material 20" or simply the "outdoor-side surface 22a," and the indoor-side surface 22 will be referred to as the "indoor-side surface 22b of the first exterior wall panel material 20" or simply the "indoor-side surface 22b." Furthermore, with respect to the first exterior wall panel material 20, the upper end face 24 will be referred to as the "upper end face 24a of the first exterior wall panel material 20" or simply as the "upper end face 24a", the lower end face 24 will be referred to as the "lower end face 24b of the first exterior wall panel material 20" or simply as the "lower end face 24b", the left end face 24 will be referred to as the "left end face 24c of the first exterior wall panel material 20" or simply as the "left end face 24c", and the right end face 24 will be referred to as the "right end face 24d of the first exterior wall panel material 20" or simply as the "right end face 24d".

[0033] Furthermore, the second exterior wall panel material 40 of this embodiment has two surfaces 42 perpendicular to the thickness direction A and four end surfaces 44 parallel to the thickness direction A. When viewed from the thickness direction A, these four end surfaces 44 form the sides of a rectangle. For ease of explanation, of the two surfaces 42 of the second exterior wall panel material 40 perpendicular to the thickness direction A, the outdoor-side surface 42 will be referred to as the "outdoor-side surface 42a of the second exterior wall panel material 40" or simply as the "outdoor-side surface 42a," and the indoor-side surface 42 will be referred to as the "indoor-side surface 42b of the second exterior wall panel material 40" or simply as the "indoor-side surface 42b." Furthermore, with respect to the second exterior wall panel material 40, the upper end face 44 will be referred to as the "upper end face 44a of the second exterior wall panel material 40" or simply as the "upper end face 44a", the lower end face 44 will be referred to as the "lower end face 44b of the second exterior wall panel material 40" or simply as the "lower end face 44b", the left end face 44 will be referred to as the "left end face 44c of the second exterior wall panel material 40" or simply as the "left end face 44c", and the right end face 44 will be referred to as the "right end face 44d of the second exterior wall panel material 40" or simply as the "right end face 44d".

[0034] Fig. 2 is a cross-sectional view taken along line II in Fig. 1. Specifically, Fig. 2 is a partial cross-sectional view of the composite exterior wall panel 1 taken along the longitudinal direction C, passing through the spacer portion 120 of the connector 100.

[0035] As described above, the connector 100 connects the first exterior wall panel material 20 and the second exterior wall panel material 40 in a state in which the first exterior wall panel material 20 and the second exterior wall panel material 40 are arranged side by side so that the end faces 24, 44 of the first exterior wall panel material 20 and the second exterior wall panel material 40 are adjacent to each other. Specifically, as shown in Figures 1 and 2, the connector 100 of this embodiment connects the first exterior wall panel material 20 and the second exterior wall panel material 40 in a state in which the first exterior wall panel material 20 and the second exterior wall panel material 40 are arranged side by side so that the lower end face 24b of the first exterior wall panel material 20 and the upper end face 44a of the second exterior wall panel material 40 are adjacent to each other.

[0036] As shown in Figures 1 and 2, a decorative groove 60 extending along the horizontal direction B is formed on the outdoor surface of at least one of the first exterior wall panel material 20 and the second exterior wall panel material 40 (in this embodiment, both the first exterior wall panel material 20 and the second exterior wall panel material 40). As shown in Figure 2, the decorative groove 60 is a groove recessed from the outdoor surface 22a of the first exterior wall panel material 20 or the outdoor surface 42a of the second exterior wall panel material 40 toward the indoor side. Note that "extending along the horizontal direction B" is not limited to extending parallel to the horizontal direction B, but also includes extending approximately parallel to the horizontal direction B, such as extending in a direction inclined at an angle equal to or less than a predetermined angle with respect to the horizontal direction B.

[0037] 2, the decorative groove 60 of this embodiment is formed so that its width gradually increases toward the exterior in the vertical direction C. Furthermore, the decorative groove 60 of this embodiment is configured so that its cross-sectional shape perpendicular to the horizontal direction B is uniform in the horizontal direction B, which is its extension direction.

[0038] As shown in Fig. 2, the connector 100 includes a spacer portion 120 sandwiched between the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40. The spacer portion 120 is sandwiched between the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40, thereby forming a joint portion 80 between the first exterior wall panel material 20 and the second exterior wall panel material 40. The joint portion 80 is a gap between the first exterior wall panel material 20 and the second exterior wall panel material 40 that is exposed to the outdoors.

[0039] The spacer portion 120 is configured to keep the maximum width W1 of the joint portion 80 when viewed from the outdoor side substantially the same as the maximum width W2 of the decorative groove 60 when viewed from the outdoor side. This allows a sense of unity between the appearance of the joint portion 80 and the appearance of the decorative groove 60, giving the composite exterior wall panel 1 an overall neat and tidy impression. In other words, it is possible to improve the design of the composite exterior wall panel 1 in which multiple exterior wall panel materials (in this embodiment, the first exterior wall panel material 20 and the second exterior wall panel material 40) are arranged side by side and the decorative groove 60 is formed on the surface of at least one of the multiple exterior wall panel materials (in this embodiment, both the first exterior wall panel material 20 and the second exterior wall panel material 40).

[0040] If the connector 100 did not include such a spacer portion 120, the relative positions of the first exterior wall panel material 20 and the second exterior wall panel material 40 would need to be adjusted by eyeballing or other methods to make the maximum width W1 of the joint portion 80 as viewed from the exterior side approximately equal to the maximum width W2 of the decorative groove 60 as viewed from the exterior side. In this case, the adjustment process would be time-consuming and labor-intensive, and differences in the skill level of the worker could result in variations in the appearance of the joint portion 80. In contrast, the composite exterior wall panel 1 allows the desired joint portion 80 to be formed simply by sandwiching the spacer portion 120 between the first exterior wall panel material 20 and the second exterior wall panel material 40. This reduces the adjustment process and prevents variations in the appearance of the joint portion 80 due to differences in the skill level of the worker. In other words, the provision of the spacer portion 120 facilitates the manufacture of a highly aesthetic composite exterior wall panel 1.

[0041] Furthermore, when this composite exterior wall panel 1 is used to construct the exterior wall of the building 500, the design of the entire exterior wall is more likely to be improved compared to when individual exterior wall panel materials are used to construct the exterior wall.

[0042] Note that "the maximum width W1 of the joint portion 80 when viewed from the outdoor side" refers to the maximum width of the joint portion 80 in the vertical direction C when viewed from the outdoor side. In this embodiment, the outdoor surface 22a of the first exterior wall panel material 20 and the outdoor surface 42a of the second exterior wall panel material 40 are located on the same plane. Therefore, in this embodiment, the maximum width W1 of the joint portion 80 when viewed from the outdoor side is the maximum width of the joint portion 80 in the vertical direction C at the positions of the outdoor surface 22a of the first exterior wall panel material 20 and the outdoor surface 42a of the second exterior wall panel material 40. Also, "the maximum width W2 of the decorative groove 60 when viewed from the outdoor side" refers to the maximum width of the decorative groove 60 in the vertical direction C when viewed from the outdoor side. The maximum width W2 of the decorative groove 60 when viewed from the outside is the maximum width in the vertical direction C of the decorative groove 60 at the position of the outside surface 22a of the first exterior wall panel material 20 in the case of the decorative groove 60 formed in the first exterior wall panel material 20, and in the case of the decorative groove 60 formed in the second exterior wall panel material 40, it is the maximum width in the vertical direction C of the decorative groove 60 at the position of the outside surface 42a of the second exterior wall panel material 40.

[0043] As shown in Fig. 2, the spacer portion 120 of this embodiment is formed in a flat plate shape. The spacer portion 120 of this embodiment is sandwiched between the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40, with the thickness direction of the spacer portion 120 aligned with the vertical direction C of the composite exterior wall panel 1. The spacer portion 120 of this embodiment is in contact with the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40, respectively, and is thereby directly sandwiched between the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40. Therefore, the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40 of this embodiment are spaced apart from each other in the vertical direction C by an amount equal to the thickness of the spacer portion 120.

[0044] As shown in FIG. 2 , a sealing portion 85 that connects the first exterior wall panel material 20 and the second exterior wall panel material 40 is provided inside the joint portion 80 of this embodiment. The sealing portion 85 of this embodiment is formed by a wet sealant filled into the joint portion 80. However, the sealing portion 85 may also be formed by a dry sealant, such as a waterproof joint rubber, placed in the joint portion 80. In this embodiment, the distance D1 from the sealing portion 85 to the exterior surface 22 a of the first exterior wall panel material 20 and the exterior surface 42 a of the second exterior wall panel material 40 is approximately equal to the depth D2 of the decorative groove 60. This provides a more unified appearance between the joint portion 80 and the decorative groove 60, giving the composite exterior wall panel 1 a more refined overall appearance.

[0045] As shown in Fig. 2, the first exterior wall panel material 20 of this embodiment has a first sealing surface 28 that connects the lower end surface 24b and the outdoor surface 22a. The first sealing surface 28 is a surface formed by cutting out a portion of the first exterior wall panel material 20. Furthermore, the second exterior wall panel material 40 of this embodiment has a second sealing surface 48 that connects the upper end surface 44a and the outdoor surface 42a. The second sealing surface 48 is a surface formed by cutting out a portion of the second exterior wall panel material 40. By providing such a first sealing surface 28 and second sealing surface 48, a sealing pocket 83 can be formed as part of the joint portion 80 between the first exterior wall panel material 20 and the second exterior wall panel material 40. The sealing pocket 83 is a gap between the first exterior wall panel material 20 and the second exterior wall panel material 40, whose width in the vertical direction C is larger than the distance between the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40. In this embodiment, a sealing portion 85 that connects the first exterior wall panel material 20 and the second exterior wall panel material 40 is formed by filling the sealing pocket 83 with a sealant.

[0046] 2, the spacer portions 120 of this embodiment are arranged relative to the first exterior wall panel material 20 and the second exterior wall panel material 40 so as not to protrude outdoors beyond the outdoor edge 24b1 of the lower end surface 24b of the first exterior wall panel material 20 and the outdoor edge 44a1 of the upper end surface 44a of the second exterior wall panel material 40. This makes the spacer portions 120 less noticeable when the composite exterior wall panel 1 is viewed from the outdoors side, thereby preventing the spacer portions 120 from impairing the design of the composite exterior wall panel 1. Furthermore, the spacer portions 120 are prevented from getting in the way when forming the sealing portion 85 that connects the first exterior wall panel material 20 and the second exterior wall panel material 40.

[0047] As shown in Fig. 1, in this embodiment, decorative grooves 60 are formed on each of the outdoor surface 22a of the first exterior wall panel 20 and the outdoor surface 42a of the second exterior wall panel 40. Specifically, in this embodiment, a plurality of (three in this embodiment) decorative grooves 60 are formed on the outdoor surface 22a of the first exterior wall panel 20, spaced apart in the vertical direction C. Furthermore, in this embodiment, a plurality of (six in this embodiment) decorative grooves 60 are formed on the outdoor surface 42a of the second exterior wall panel 40, spaced apart in the vertical direction C. In this embodiment, the plurality of decorative grooves 60 formed on the outdoor surface 22a of the first exterior wall panel 20 and the plurality of decorative grooves 60 formed on the outdoor surface 42a of the second exterior wall panel 40 have the same shape.

[0048] As shown in Fig. 1, in this embodiment, the spacing S2 between adjacent decorative grooves 60 when viewed from the outdoor side is configured to be approximately constant. Also, in this embodiment, the spacing S1 between joint portions 80 and the decorative grooves 60 adjacent to the joint portions 80 when viewed from the outdoor side is configured to be approximately constant. And, in this embodiment, the spacing S1 is configured to approximately match the spacing S2. By doing so, when multiple decorative grooves 60 are formed on the outdoor surface 22a of the first exterior wall panel material 20 or the outdoor surface 42a of the second exterior wall panel material 40, the composite exterior wall panel 1 as a whole can give the impression of being neat and tidy.

[0049] Next, the first exterior wall panel material 20 and the second exterior wall panel material 40 of this embodiment will be described in detail.

[0050] Fig. 3 is a cross-sectional view taken along line II-II in Fig. 1. Specifically, Fig. 3 is a cross-sectional view of the composite exterior wall panel 1 along the horizontal direction B, passing through the spacer portion 120 of the connector 100. Fig. 4 is a cross-sectional view taken along line III-III in Fig. 1. Specifically, Fig. 4 is a cross-sectional view of the composite exterior wall panel 1 along the horizontal direction B, passing through the fastening member 150 that fixes the connector 100 to the panel unit 200. Fig. 5 is a diagram showing the composite exterior wall panels 1 shown in Fig. 1 connected in the horizontal direction B. Fig. 5 shows a cross-section at the same position as Fig. 4.

[0051] As shown in Fig. 1, the first exterior wall panel material 20 of this embodiment has a rectangular shape with the longitudinal direction being the vertical direction C and the short side being the horizontal direction B when viewed from the thickness direction A. Furthermore, the second exterior wall panel material 40 of this embodiment has a rectangular shape with the longitudinal direction being the vertical direction C and the short side being the horizontal direction B when viewed from the thickness direction A. However, the shapes of the first exterior wall panel material 20 and the second exterior wall panel material 40 are not limited to the configuration of this embodiment.

[0052] The first exterior wall panel material 20 and the second exterior wall panel material 40 of this embodiment have substantially the same length in the thickness direction A and the same length in the width direction B. However, the first exterior wall panel material 20 and the second exterior wall panel material 40 of this embodiment have different lengths in the vertical direction C. Specifically, in this embodiment, the length in the vertical direction C of the second exterior wall panel material 40 is greater than the length in the vertical direction C of the first exterior wall panel material 20. However, the size relationship between the first exterior wall panel material 20 and the second exterior wall panel material 40 is not limited to the configuration of this embodiment. For example, the lengths in the vertical direction C of the first exterior wall panel material 20 and the second exterior wall panel material 40 may be the same, or the length in the vertical direction C of the first exterior wall panel material 20 may be greater than the length in the vertical direction C of the second exterior wall panel material 40.

[0053] The first exterior wall panel material 20 of this embodiment includes rib members 30 extending in the vertical direction C. In other words, the first exterior wall panel material 20 of this embodiment includes a panel main body 31 that forms the exterior shape, and rib members 30 embedded in the panel main body 31. By including the rib members 30 in this manner, the strength of the first exterior wall panel material 20 can be improved. The first exterior wall panel material 20 of this embodiment also includes a plurality of rib members 30. These plurality of rib members 30 are arranged spaced apart from each other in the horizontal direction B. The first exterior wall panel material 20 of this embodiment includes two rib members 30 as the plurality of rib members 30. However, the first exterior wall panel material 20 may be configured to include three or more rib members 30 as the plurality of rib members 30.

[0054] The second exterior wall panel material 40 of this embodiment includes rib members 50 extending in the vertical direction C. In other words, the second exterior wall panel material 40 of this embodiment includes a panel main body 51 that forms the outer shape, and rib members 50 embedded in the panel main body 51. By including the rib members 50 in this manner, the strength of the second exterior wall panel material 40 can be improved. The second exterior wall panel material 40 of this embodiment also includes a plurality of rib members 50. These plurality of rib members 50 are arranged spaced apart from each other in the horizontal direction B. The second exterior wall panel material 40 of this embodiment includes two rib members 50 as the plurality of rib members 50. However, the second exterior wall panel material 40 may be configured to include three or more rib members 50 as the plurality of rib members 50.

[0055] In this embodiment, the panel body 31 of the first exterior wall panel 20 and the panel body 51 of the second exterior wall panel 40 are made of ALC. That is, the first exterior wall panel 20 and the second exterior wall panel 40 are so-called ALC panels. However, the materials for the panel body 31 of the first exterior wall panel 20 and the panel body 51 of the second exterior wall panel 40 are not limited to the configuration of this embodiment and may be, for example, metal, cement, a nitride-based material, or a wood-based material. Furthermore, the frame members 30 of the first exterior wall panel 20 and the frame members 50 of the second exterior wall panel 40 are, for example, reinforcing bars. However, they may be made of materials other than reinforcing bars as long as they can improve the strength of the first exterior wall panel 20 and the second exterior wall panel 40. Furthermore, the cross-sectional shape of the frame members 30 and 50 in this embodiment is circular, but is not limited to the configuration of this embodiment and may be, for example, elliptical or polygonal.

[0056] The first exterior wall panel 20 and the second exterior wall panel 40 of this embodiment, when connected to the connector 100, form a panel unit 200 that is generally rectangular overall. The panel unit 200 of this embodiment has a generally rectangular shape when viewed from the thickness direction A. In other words, when connected to the connector 100, the first exterior wall panel 20 and the second exterior wall panel 40 of this embodiment are arranged such that the left end face 24c of the first exterior wall panel 20 and the left end face 44c of the second exterior wall panel 40 are positioned on generally the same plane. Furthermore, when connected to the connector 100, the first exterior wall panel 20 and the second exterior wall panel 40 of this embodiment are arranged such that the right end face 24d of the first exterior wall panel 20 and the right end face 44d of the second exterior wall panel 40 are positioned on generally the same plane. In other words, in the panel unit 200 of this embodiment, four end faces 240 perpendicular to the thickness direction A are formed by the upper end face 24a of the first exterior wall panel material 20, the lower end face 44b of the second exterior wall panel material 40, the left end face 24c of the first exterior wall panel material 20 and the left end face 44c of the second exterior wall panel material 40, and the right end face 24d of the first exterior wall panel material 20 and the right end face 44d of the second exterior wall panel material 40.

[0057] Furthermore, the first exterior wall panel 20 and the second exterior wall panel 40 of this embodiment are arranged so that, when connected to the connector 100, the outdoor surface 22a of the first exterior wall panel 20 and the outdoor surface 42a of the second exterior wall panel 40 are positioned on approximately the same plane. Furthermore, the first exterior wall panel 20 and the second exterior wall panel 40 of this embodiment are arranged so that, when connected to the connector 100, the indoor surface 22b of the first exterior wall panel 20 and the indoor surface 42b of the second exterior wall panel 40 are positioned on approximately the same plane. In other words, in the panel unit 200 of this embodiment, two surfaces 210 parallel to the thickness direction A are formed by the outdoor surface 22a of the first exterior wall panel 20 and the outdoor surface 42a of the second exterior wall panel 40, and the indoor surface 22b of the first exterior wall panel 20 and the indoor surface 42b of the second exterior wall panel 40.

[0058] Hereinafter, for ease of explanation, the outdoor surface 210 of the panel unit 200 of this embodiment will be referred to as the "outdoor surface 210a of the panel unit 200" or simply as the "outdoor surface 210a", and the indoor surface 210 of the panel unit 200 will be referred to as the "indoor surface 210b of the panel unit 200" or simply as the "indoor surface 210b". Furthermore, in the panel unit 200 of this embodiment, the upper end face 240 will be referred to as the "upper end face 240a of the panel unit 200" or simply as the "upper end face 240a", the lower end face 240 will be referred to as the "lower end face 240b of the panel unit 200" or simply as the "lower end face 240b", the left end face 240 will be referred to as the "left end face 240c of the panel unit 200" or simply as the "left end face 240c", and the right end face 240 will be referred to as the "right end face 240d of the panel unit 200" or simply as the "right end face 240d".

[0059] As shown in FIGS. 3 and 4, the panel unit 200 of this embodiment includes a first cutout surface 250a and a second cutout surface 250b. The first cutout surface 250a of this embodiment connects the outdoor surface 210a and the left end surface 240c of the panel unit 200. The first cutout surface 250a of this embodiment extends at an angle with respect to the thickness direction A so that substantially the entire surface faces the outdoor side and the left side. The outdoor surface 210a, the first cutout surface 250a, and the left end surface 240c of the panel unit 200 of this embodiment have a shape in which right-angle corners are cut off in a cross section perpendicular to the vertical direction C (see FIG. 4). The second cutout surface 250b of this embodiment connects the outdoor surface 210a and the right end surface 240d of the panel unit 200. In this embodiment, the second cutout surface 250b extends at an incline in the thickness direction A so that almost the entire area faces the exterior and right side. The exterior surface 210a, the second cutout surface 250b, and the right end surface 240d of the panel unit 200 in this embodiment have a shape in which right-angled corners are cut off in a cross section perpendicular to the vertical direction C (see FIG. 4). By providing such first cutout surface 250a and second cutout surface 250b, the composite exterior wall panel 1 in this embodiment can form a sealing pocket 300 between adjacent composite exterior wall panels 1 in the horizontal direction B, the width of which gradually increases toward the exterior in the horizontal direction B (see FIG. 5). In the exterior wall of the building 500 in this embodiment, a sealing material is filled in this sealing pocket 300 to form a sealing portion 301 that joins adjacent composite exterior wall panels 1 in the horizontal direction B (see FIG. 5).

[0060] As shown in FIGS. 3 and 4, the panel unit 200 of this embodiment includes a first chamfered surface 260a and a second chamfered surface 260b. Specifically, the first chamfered surface 260a of this embodiment is a surface connecting the indoor-side surface 210b and the left end surface 240c of the panel unit 200. The first chamfered surface 260a of this embodiment is inclined with respect to the thickness direction A so as to face the indoor side and the left side, and extends in a planar shape. In a cross-sectional view perpendicular to the vertical direction C (see FIG. 4), the indoor-side surface 210b, the first chamfered surface 260a, and the left end surface 240c of the panel unit 200 of this embodiment have a shape in which right-angled corners are cut off linearly. The second chamfered surface 260b of this embodiment is a surface connecting the indoor-side surface 210b and the right end surface 240d of the panel unit 200. The second chamfered surface 260b in this embodiment is inclined with respect to the thickness direction A so as to face the indoor side and the right side, and extends in a plane. The indoor side surface 210b, the second chamfered surface 260b, and the right end surface 240d of the panel unit 200 in this embodiment have a shape in which right-angled corners are cut off in a straight line in a cross section perpendicular to the vertical direction C (see FIG. 4). By providing such a first chamfered surface 260a and a second chamfered surface 260b, it is possible to remove corners of the panel unit 200 that are prone to damage such as cracks and chips. As a result, damage to the panel unit 200 during handling can be reduced.

[0061] Next, the details of the connector 100 of this embodiment will be described.

[0062] The composite exterior wall panel 1 of this embodiment includes two connectors 100. These two connectors 100 are arranged on both sides of the panel unit 200 in the horizontal direction B. For ease of explanation, the connector 100 arranged on the left side of the panel unit 200 in the horizontal direction B may be referred to as the "first connector 100a," and the connector 100 arranged on the right side of the panel unit 200 in the horizontal direction B may be referred to as the "second connector 100b." When there is no need to distinguish between the first connector 100a and the second connector 100b, they will simply be referred to as "connectors 100." In this embodiment, the first connector 100a and the second connector 100b have similar configurations. Therefore, the following description will mainly focus on the first connector 100a, and in the second connector 100b, components corresponding to those of the first connector 100a may be designated by the same reference numerals and their description may be omitted.

[0063] The first connecting body 100a of this embodiment includes a connecting portion 110 that connects the first exterior wall panel material 20 and the second exterior wall panel material 40, and the spacer portion 120 described above.

[0064] Specifically, the connecting portion 110 of the first connecting body 100a of this embodiment extends across the first exterior wall panel material 20 and the second exterior wall panel material 40, and is fixed to each of the first exterior wall panel material 20 and the second exterior wall panel material 40, thereby connecting the first exterior wall panel material 20 and the second exterior wall panel material 40. The spacer portion 120 of the first connecting body 100a of this embodiment is provided to protrude from the connecting portion 110. In this manner, the connecting body 100, which is integrally provided with the connecting portion 110 and the spacer portion 120, can be realized with a simple configuration.

[0065] More specifically, the connecting portion 110 of the first connecting body 100a of this embodiment includes a base portion 112 and a side wall portion 114. The base portion 112 extends in the vertical direction C so as to straddle the first exterior wall panel material 20 and the second exterior wall panel material 40, and covers the indoor-side surface 210b of the panel unit 200. The composite exterior wall panel 1 of this embodiment includes fastening members 150 that fix the first connecting body 100a to the first exterior wall panel material 20 and the second exterior wall panel material 40. The fastening members 150 of this embodiment are bolts. The base portion 112 of this embodiment has a plurality of insertion holes formed at intervals in the vertical direction C, through which the bolts serving as the fastening members 150 can be inserted. The bolts serving as the fastening members 150 are inserted through the insertion holes of the base portion 112 from the indoor side toward the outdoor side, into the first exterior wall panel material 20 and the second exterior wall panel material 40, respectively. The connecting portion 110 of this embodiment is fixed to the first exterior wall panel material 20 and the second exterior wall panel material 40 by being sandwiched between the indoor side surface 22b of the first exterior wall panel material 20 and the indoor side surface 42b of the second exterior wall panel material 40 and the head of the bolt serving as the fastening member 150, with the shank of the bolt being inserted into the insertion hole of the base portion 112. The connecting portion 110 of this embodiment connects the first exterior wall panel material 20 and the second exterior wall panel material 40 in this manner.

[0066] The side wall portion 114 is continuous with the base portion 112 and covers the left end surface 240c of the panel unit 200. In other words, the connecting portion 110 of this embodiment covers the panel unit 200 from the left end surface 240c of the panel unit 200 to the indoor side surface 210b with the base portion 112 and the side wall portion 114. This makes it possible to protect the panel unit 200 from impacts and the like from the left end surface 240c of the panel unit 200 to the indoor side surface 210b. As a result, it is possible to prevent the panel unit 200 from being damaged during handling, such as during transportation or assembly.

[0067] 3, the spacer portion 120 of this embodiment is provided to protrude from the base portion 112 of the connecting portion 110. However, the spacer portion 120 is not limited to the configuration of this embodiment, and may be provided to protrude from the side wall portion 114, or may be provided to protrude from both the base portion 112 and the side wall portion 114, for example.

[0068] In this embodiment, the connecting portion 110 of the first connecting body 100a is attached to the panel unit 200 in a state in which it abuts against the left end face 240c and the indoor side surface 210b of the panel unit 200. This reinforces the strength of the panel unit 200 and prevents the panel unit 200 from being damaged during handling, such as during transportation or assembly. However, the first connecting body 100a may also be attached to the panel unit 200 in a state in which another member, such as a rubber sheet, is sandwiched between the first connecting body 100a and the left end face 240c and the indoor side surface 210b of the panel unit 200.

[0069] The base portion 112 and the side wall portion 114 of this embodiment are each configured in a flat plate shape. The cross-sectional shape of the connecting portion 110 of this embodiment, which is perpendicular to the longitudinal direction C as the extending direction, is substantially L-shaped. The connecting portion 110 of this embodiment is formed so that the base portion 112 and the side wall portion 114 are integrated by joining such as bending or welding, or by integral molding such as extrusion molding. However, the connecting portion 110 may be configured so that the base portion 112 and the side wall portion 114 are connected by fastening members such as bolts, for example.

[0070] As described above, the spacer portion 120 of this embodiment is configured in a flat plate shape. The spacer portion 120 of this embodiment is formed to be integrated with the connecting portion 110 by joining such as welding, or by integral molding such as extrusion molding. However, the spacer portion 120 may be configured to be fixed to the connecting portion 110 by a fastening member such as a bolt, for example.

[0071] The material forming the connecting body 100 in this embodiment is, for example, steel, but this may be changed appropriately depending on the material forming the panel unit 200, and may be, for example, a metal other than steel, a hard resin, or a wood-based material.

[0072] The base portion 112 of the first connector 100a of this embodiment extends to a position between the two outer rib members 30a located outermost on both sides in the lateral direction B among the multiple rib members 30 of the first exterior wall panel 20. The fastening member 150 of this embodiment is inserted into the first exterior wall panel 20 between the two outer rib members 30a through the base portion 112 of the connecting portion 110 of the first connector 100a. This makes it possible to prevent damage to the first exterior wall panel 20, such as cracking of the end portion in the lateral direction B, when the fastening member 150 is inserted into the first exterior wall panel 20. Note that the first exterior wall panel 20 of this embodiment has only two rib members 30, and both of these rib members 30 are outer rib members 30a.

[0073] The composite exterior wall panel 1 of this embodiment includes only fastening members 150 positioned between the two outer rib members 30a as fastening members 150 inserted into the first exterior wall panel material 20 through the base portion 112 of the first connector 100a, and does not include fastening members 150 positioned outside the two outer rib members 30a. However, the arrangement of the fastening members 150 is not limited to the configuration of this embodiment. For example, the composite exterior wall panel 1 may include both fastening members 150 positioned between the two outer rib members 30a and fastening members 150 positioned outside the two outer rib members 30a as fastening members 150 inserted into the first exterior wall panel material 20 through the base portion 112 of the first connector 100a. Furthermore, the composite exterior wall panel 1 may include only the fastening members 150 located on the outside of the two outer rib members 30a as fastening members 150 inserted into the first exterior wall panel material 20 through the base portions 112 of the first connectors 100a, and may not include the fastening members 150 located between the two outer rib members 30a. However, as described above, from the viewpoint of suppressing damage to the first exterior wall panel material 20, it is preferable that the composite exterior wall panel 1 include the fastening members 150 located between the two outer rib members 30a as fastening members 150 inserted into the first exterior wall panel material 20 through the base portions 112 of the first connectors 100a. Note that "fastening members 150 located on the outside of the two outer rib members 30a" refers to fastening members 150 located on the side of the two outer rib members 30a that is away from the center of the first exterior wall panel material 20 in the orthogonal direction C.

[0074] Furthermore, the base portion 112 of the first connector 100a of this embodiment extends to a position between the two outer rib members 50a located outermost on both sides in the lateral direction B among the multiple rib members 50 of the second exterior wall panel 40. The fastening member 150 of this embodiment is inserted into the second exterior wall panel 40 between the two outer rib members 50a through the base portion 112 of the connecting portion 110 of the first connector 100a. This makes it possible to prevent damage to the second exterior wall panel 40, such as cracking of the end portion in the lateral direction B, when the fastening member 150 is inserted into the second exterior wall panel 40. Note that the second exterior wall panel 40 of this embodiment has only two rib members 50, and both of these rib members 50 are outer rib members 50a.

[0075] The composite exterior wall panel 1 of this embodiment includes only fastening members 150 located between the two outer rib members 50a as fastening members 150 inserted into the second exterior wall panel material 40 through the base portion 112 of the first connector 100a, and does not include fastening members 150 located outside the two outer rib members 50a. However, the arrangement of the fastening members 150 is not limited to the configuration of this embodiment. For example, the composite exterior wall panel 1 may include both fastening members 150 located between the two outer rib members 50a and fastening members 150 located outside the two outer rib members 50a as fastening members 150 inserted into the second exterior wall panel material 40 through the base portion 112 of the first connector 100a. Furthermore, the composite exterior wall panel 1 may include only the fastening members 150 located on the outside of the two outer rib members 50a as the fastening members 150 inserted into the second exterior wall panel material 40 through the base portions 112 of the first connectors 100a, and may not include the fastening members 150 located between the two outer rib members 50a. However, as mentioned above, from the viewpoint of suppressing damage to the second exterior wall panel material 40, it is preferable that the composite exterior wall panel 1 include the fastening members 150 located between the two outer rib members 50a as the fastening members 150 inserted into the second exterior wall panel material 40 through the base portions 112 of the first connectors 100a. Note that "fastening members 150 located on the outside of the two outer rib members 50a" refers to fastening members 150 located on the side of the two outer rib members 50a that is away from the center of the second exterior wall panel material 40 in the orthogonal direction C.

[0076] As shown in Figures 3 and 4, the first connector 100a of this embodiment is fixed to the panel unit 200 so as not to protrude outdoors beyond the outdoor end 240c1 of the left end face 240c of the panel unit 200. Similarly, the second connector 100b of this embodiment is fixed to the panel unit 200 so as not to protrude outdoors beyond the outdoor end 240d1 of the right end face 24dc of the panel unit 200. This makes the connector 100 less noticeable when the composite exterior wall panel 1 is viewed from the outdoors side, preventing the connector 100 from impairing the design of the composite exterior wall panel 1. Furthermore, the connector 100 is prevented from getting in the way when forming a sealing portion 301 (see Figure 5) between the composite exterior wall panel 1 and another composite exterior wall panel 1 adjacent in the horizontal direction B.

[0077] As shown in FIG. 1, the panel unit 200 of this embodiment protrudes on both sides in the vertical direction C beyond the first connecting body 100a. In other words, the upper end surface 240a of the panel unit 200 of this embodiment is located above the upper end of the first connecting body 100a, and the lower end surface 240b is located below the lower end of the first connecting body 100a. Therefore, the connecting body 100 is not disposed at both ends of the panel unit 200 of this embodiment in the vertical direction C. These ends of the panel unit 200 on both sides in the vertical direction C can function as attachment portions for attaching the panel unit 200 to a structural frame 501. Specifically, in the building 500 of this embodiment, the composite exterior wall panel 1 is arranged so that the vertical direction C coincides with the vertical direction. In the building 500 of this embodiment, the upper end of the panel unit 200 is attached to an upper beam 501a as part of the structural frame 501, and the lower end of the panel unit 200 is attached to a lower beam 501b as part of the structural frame 501 (see FIG. 1). In this way, by attaching the ends on both sides of the panel unit 200 in the vertical direction C to the structural frame 501 as attachment parts, the connector 100 can be prevented from getting in the way when attaching the composite exterior wall panel 1 to the structural frame 501.

[0078] As described above, the composite exterior wall panel 1 of this embodiment includes the second connector 100b in addition to the first connector 100a. The second connector 100b connects the first exterior wall panel material 20 and the second exterior wall panel material 40, and covers the panel unit 200 from the left end face 240c of the panel unit 200 to the right end face 240d opposite the left end face 240c, and the indoor-side surface 210b of the panel unit 200. This allows the first exterior wall panel material 20 and the second exterior wall panel material 40 to be connected more firmly than when the composite exterior wall panel 1 includes only the first connector 100a. Furthermore, in addition to the area extending from the left end face 240c of the panel unit 200 to the indoor side surface 210b, the panel unit 200 can be protected from impacts and the like in the area extending from the right end face 240d of the panel unit 200 to the indoor side surface 210b, and damage to the panel unit 200 during handling, such as during transportation or assembly, can be more effectively prevented compared to when the composite exterior wall panel 1 has only the first connecting body 100a.

[0079] Furthermore, by providing the first and second connecting bodies 100a and 100b as separate bodies, even if the length of the panel unit 200 in the horizontal direction B varies due to dimensional tolerances or the like, the first and second connecting bodies 100a and 100b can be easily attached to the panel unit 200. Specifically, for example, if the composite exterior wall panel 1 is configured to have a single connecting body that covers the panel unit 200 from both end faces 240 in the horizontal direction B of the panel unit 200 to the indoor-side surface 210b, if the length of the panel unit 200 in the horizontal direction B varies due to dimensional tolerances or the like, the shape of the panel unit 200 and the shape of the connecting body may not match, making it difficult to attach the connecting body to the panel unit 200. In contrast, in the present embodiment, where the composite exterior wall panel 1 is configured to have a first connecting body 100a and a second connecting body 100b that are separate from each other, even if the length of the panel unit 200 in the horizontal direction B varies due to dimensional tolerances, etc., the first connecting body 100a and the second connecting body 100b can be easily attached to the panel unit 200 by adjusting the relative positions of the first connecting body 100a and the second connecting body 100b.

[0080] More specifically, in this embodiment, the first connecting body 100a and the second connecting body 100b are arranged so that a gap X is formed between them in the horizontal direction B at any position in the vertical direction C when they are fixed to the panel unit 200 (see FIGS. 3 and 4). By providing such a gap X, it is possible to prevent the first connecting body 100a and the second connecting body 100b from interfering with each other even if the length of the panel unit 200 in the horizontal direction B varies due to dimensional tolerances or the like. In other words, the first connecting body 100a and the second connecting body 100b can be easily attached to the panel unit 200 even if the length of the panel unit 200 in the horizontal direction B varies due to dimensional tolerances or the like.

[0081] The composite exterior wall panel 1 of this embodiment is elongated in the vertical direction C. Conventionally, elongated exterior wall panel materials have been prone to damage such as cracks and chips during handling, making them difficult to use in manufacturing the building 500. In contrast, the composite exterior wall panel 1 of this embodiment is provided with the connector 100, which can reduce damage to the exterior wall panel materials (the first exterior wall panel material 20 and the second exterior wall panel material 40 in this embodiment) during handling. In other words, even though the composite exterior wall panel 1 of this embodiment has an elongated configuration, it is easy to use in manufacturing the building 500. This reduces constraints on the shape of the composite exterior wall panel 1, thereby increasing the degree of freedom in designing the building 500. Note that "elongated in the vertical direction C" means that the length of the composite exterior wall panel 1 in the vertical direction C is greater than the length of the composite exterior wall panel 1 in the horizontal direction B. Specifically, the composite exterior wall panel 1 of this embodiment may be configured so that the ratio of the length in the vertical direction C to the length in the horizontal direction B is preferably 10-30, more preferably 12-25, and even more preferably 15-20.

[0082] Furthermore, the composite exterior wall panel 1 of this embodiment is configured so that its length in the horizontal direction B is equal to or less than a predetermined value. Conventionally, exterior wall panel materials whose length in the horizontal direction B is equal to or less than a predetermined value are prone to damage, such as cracks and chips, during handling, making them difficult to use in the manufacture of the building 500. In contrast, the composite exterior wall panel 1 of this embodiment includes the connector 100, which can reduce damage to the exterior wall panel materials (the first exterior wall panel material 20 and the second exterior wall panel material 40 in this embodiment) during handling. In other words, the composite exterior wall panel 1 of this embodiment is easy to use in the manufacture of the building 500 even if its length in the horizontal direction B is equal to or less than a predetermined value. This reduces constraints on the shape of the composite exterior wall panel 1, thereby increasing the degree of freedom in the design of the building 500. Specifically, the composite exterior wall panel 1 of this embodiment may be configured so that the predetermined value is preferably 200 mm, more preferably 160 mm, and even more preferably 144 mm.

[0083] The composite exterior wall panel 1 and building 500 of the present invention are not limited to the specific configurations shown in the above-mentioned embodiments, and various modifications, changes, and combinations are possible as long as they do not deviate from the scope of the claims.

[0084] For example, in the above embodiment, an example is shown in which the composite exterior wall panel 1 is attached to the structural body 501 with the longitudinal direction C of the composite exterior wall panel 1 aligned with the vertical direction, but the composite exterior wall panel 1 may also be attached to the structural body 501 with the transverse direction B aligned with the vertical direction.

[0085] Furthermore, in the above-described embodiment, an example was described in which the spacer portion 120 of the connecting body 100 is abutted against the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40, thereby being directly sandwiched between the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40, but the spacer portion 120 may also be indirectly sandwiched between the lower end surface 24b of the first exterior wall panel material 20 and the upper end surface 44a of the second exterior wall panel material 40 via another member such as a rubber sheet.

[0086] Furthermore, in the above-described embodiment, a composite exterior wall panel 1 comprising two exterior wall panel materials (a first exterior wall panel material 20 and a second exterior wall panel material 40) is exemplified, but the composite exterior wall panel of the present invention may comprise three or more exterior wall panel materials.
