[First embodiment]
<Exterior material>
First, the exterior material 1 according to the first embodiment will be described with reference to FIGS. 1 to 3A and 4A.

The exterior material 1 is an exterior material provided on a building 8 . The exterior material 1 includes a connecting portion 201, a groove 2, a first end T1, and a second end T2. The first end T1 is located at one of both ends of the exterior material 1 along one direction (the direction perpendicular to the length direction of the groove 2) X (the left end in FIG. 1). The second end T2 is located at the other of both ends of the exterior material 1 along the one direction X (the right end in FIG. 1). One end of the connecting portion 201 is at the first end T1. The groove 2 is positioned along the second end T2. The recessed groove 2 has a shallow groove 231 recessed toward the first end T1 on the bottom side thereof. The connecting portion 201 has a tip portion 212 for connecting to the shallow groove 231 .

In the exterior material 1, the connection part 201 has the tip part 212 and the recessed groove 2 has the shallow groove 231, so that the tip part 212 is connected to the shallow groove 231 when providing a plurality of exterior materials 1 in the building 8. do. As a result, the positioning of each exterior material 1 is facilitated, and the exterior material 1 can be made to follow and be fixed to the foundation material even if unevenness occurs in the foundation material such as a purlin. Moreover, even if the recessed groove 2 has the shallow groove 231, a plurality of exterior materials 1 can be stacked and transported. Therefore, the transportation cost of the exterior material 1 can be suppressed.

As shown in FIG. 1, the exterior material 1 is formed from one plate (for example, a rectangular plate in a plan view). Examples of plate materials include metal plates and plastic plates. When the exterior material 1 is formed of a metal plate, the metal plate has a thickness of 0.27 mm or more, for example. Examples of metal sheets include steel sheets, plated steel sheets containing zinc or the like, Galvalume steel sheets (registered trademark), and painted steel sheets. The exterior material 1 is formed into an arbitrary shape by, for example, bending a sheet of metal plate by roll forming or the like. For example, in one direction X, the shape between the connection portion 201 and the groove 2 may be flat, and a groove (a groove 21 to be described later) different from the groove 2 may be formed between the connection portion 201 and the groove 2 . 2 may be formed.

The exterior material 1 has a working width W as shown in FIG. The direction of the working width W is parallel to the one direction X. The dimension of the working width W (horizontal dimension in FIG. 2) is arbitrarily formed, but is, for example, 500 mm to 800 mm. Moreover, the exterior material 1 can be processed into an arbitrary length according to various uses such as the size of the building 8 and the installation position of the exterior material 1 . Therefore, the length L of the exterior material 1 used at the construction site may be long or short. When the exterior material 1 has grooves different from the grooves 2, for example, the exterior material 1 having a working width W of 600 mm to 800 mm is formed by bending a metal plate having a width of 914 mm.

The groove 2 is an elongated trough along a direction perpendicular to the one direction X (for example, the vertical direction Z of the building 8). For this reason, the groove 2 is formed so as to open to the outside. The length of the groove 2 is the same as the length L as shown in FIG.

Further, as shown in FIG. 4A, the groove 2 has a first side 24 and a second side (contact side) 25 forming the open end. The groove 2 further comprises a bottom piece 236 . The bottom piece 236 constitutes the bottom of the groove 2 and is connected to the shallow groove 231 and side pieces 233 which will be described later. The first side 24 is located on the first end T1 side of the opening ends of the groove 2 in the one direction X. As shown in FIG. The second side 25 is located on the second end T2 side of the opening ends of the groove 2 in the one direction X, and when the connection portion 201 is superimposed on the groove 2, the second side 25 It contacts the back surface of the exterior material 1 on the outside. Moreover, the groove 2 has a depth H. As shown in FIG. Depth H is the dimension between bottom piece 236 and first side 24 . The depth H is, for example, 10 mm or more and 50 mm or less. The groove 2 has a width W2 (see FIG. 2). The direction of the width W2 is parallel to the one direction X. The width W2 can be set arbitrarily, but is, for example, 70 mm.

The shallow groove 231 is located on the outdoor side of the bottom piece 236 and is recessed in the one direction X toward the first end T1. When the side piece 211 is pressed against the receiving piece 234, such a shallow groove 231 has at least the connection portion 201 directed indoors in a fan-shaped orbit around the portion where the tip portion 212 and the shallow groove 231 are connected as an axis. Allow movement (see FIGS. 5B and 5C). Also, the shallow groove 231 is connected to a bottom piece 236 and an inclined piece 232, which will be described later, and has a length. The longitudinal direction of the shallow groove 231 is orthogonal to the one direction X. As shown in FIG. The length of the shallow groove 231 is the same as the length L of the exterior material 1 . Also, the shallow groove 231 has a width W8 and a depth H11. The direction of the width W8 is orthogonal to the one direction X, and the direction of the depth H11 is parallel to the one direction X. The width W8 is preferably 2 mm or more and 7 mm or less. The depth H11 is preferably greater than 0 mm and 3 mm or less. In one example of this embodiment, the width W8 is 5 mm and the depth H11 is 2 mm.

The receiving piece 234 is connected to the side piece 233 and the second side 25 and is inclined from the side piece 233 toward the indoor side. Specifically, the receiving piece 234 is interposed between the side piece 233 and the second side 25 and is inclined from the tip of the side piece 233 toward the second end T2. In such a groove 2, the second side 25 is preferably on the opposite side of the first side 24 from the bottom surface (bottom piece 236). This preferred embodiment includes an embodiment in which the dimension H2 between the second side 25 and the bottom piece 236 and the depth H are the same, and an embodiment in which the dimension H2 is greater than the depth H. In a preferred embodiment, with the connection part 201 overlaid on the groove 2 , the receiving piece 234 can reliably contact the back surface of the connection part 201 due to the elasticity of the side piece 233 while retracting toward the indoor side. As a result, even if water droplets such as rainwater enter between the groove 2 and the connection portion 201, the contact portion between the receiving piece 234 and the connection portion 201 can easily obtain a water stop. Moreover, when the dimension H2 is larger than the depth H, the second side 25 is arranged so as to be on the outdoor side of the first side 24 . Although the dimension H2 is not specifically limited, it is, for example, 15 mm.

Moreover, the exterior material 1 further includes a top plate piece 235 . The top plate piece 235 is interposed between the second side 25 and the second end T2.

In the exterior material 1 according to this embodiment, the connecting portion 201 is an elongated portion along the direction orthogonal to the one direction X. As shown in FIG.
