[0022] [Figure 1] FIG. 2 is a cross-sectional view of the outer wall of the present embodiment taken along the XY plane. [Figure 2]FIG. 2 is a partially enlarged view of the joint portion of FIG. [Figure 3] FIG. [Figure 4] 1 is a flowchart showing the flow of a joining method. DETAILED DESCRIPTION OF THE INVENTION

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Note that the drawings are schematic illustrations.

[0024] [1. Description of the configuration] Fig. 1 is a cross-sectional view in the XY plane of an exterior wall 1000. Fig. 2 is a partially enlarged view of a joint A shown in Fig. 1. Hereinafter, the X-axis direction is defined as the width direction of the exterior wall 1000. The positive side of the Y-axis direction is defined as the indoor side in the thickness direction of the exterior wall 1000, and the negative side of the Y-axis direction is defined as the outdoor side in the thickness direction of the exterior wall 1000. The positive side of the Z-axis direction is defined as the upper side in the vertical direction, and the negative side of the Z-axis direction is defined as the lower side in the vertical direction.

[0025] The exterior wall 1000 includes a plurality of exterior wall panels 100, an interior material 200, a joint member 300, a first fixing member 400, and a second fixing member 500.

[0026] The exterior wall panel 100 comprises an exterior material 10, a panel body 20, a spacer member 30, a first L-shaped member 41, and a second L-shaped member 42.

[0027] The exterior material 10 is formed of a steel plate or the like, faces an outdoor space, and is in the form of a panel. Moreover, the exterior packaging material 10 includes a main body plate portion 11, an end surface plate portion 121, and an end surface plate portion 122. The main body plate 11 covers the surface on the negative side in the Y-axis direction (thickness direction) of the panel main body 20. In other words, the main body plate 11 is provided on the surface of the panel main body 20 facing outdoors. The end panel portion 121 is connected to the positive end portion in the X-axis direction of the main body panel portion 11 (one end portion in the width direction of the exterior material 10) via a bending portion, and is overlapped on the other piece 41b (described later) of the first L-shaped member 41. The end panel portion 122 is connected to the negative end portion in the X-axis direction of the main body panel portion 11 (the other end portion in the width direction of the exterior material 10) via a bending portion, and is overlapped on the other piece 42b (described later) of the second L-shaped member 42.

[0028] As shown in FIGS. 1 and 2, the panel body 20 is joined to the surface of the body plate portion 11 of the exterior packaging material 10 on the positive side in the Y-axis direction by adhesive or the like. In the panel main body 20, as shown in Figure 3, vertical frame members 21 and horizontal frame members 22 are assembled into a rectangular shape, and reinforcing core members 23 are assembled vertically and horizontally inside this rectangular frame to form a frame body 24, and face materials 25 such as plywood are attached to both surfaces of the frame body 24 in the Y-axis direction (thickness direction). The panel body 20 also includes a rectangular frame formed by the frame 24 and a heat insulating material 26 (FIGS. 1 and 2) such as glass wool or rock wool.

[0029] The spacer member 30 is formed from a wooden block or the like. 1 and 2, the spacer member 30 is bonded to the X-axis direction positive side end (one width direction end) of the panel main body 20 with an adhesive or the like, and is provided over the entire length of the panel main body 20 in the Z-axis direction (height direction). The spacer member 30 is provided so as to be positioned on approximately the same plane as the panel main body 20 of the adjacent exterior wall panel 100 on the Y-axis direction positive side. In other words, the spacer member 30 is provided along the indoor side of the exterior wall panel 100. Furthermore, the length of the spacer member 30 in the Y-axis direction is shorter than the length (thickness) of the panel main body 20 in the Y-axis direction.

[0030] The first L-shaped member 41 and the second L-shaped member 42 are joined to the panel main body 20 over the entire length of the panel main body 20 in the Z-axis direction (height direction). The first L-shaped member 41 is provided along the outdoor side of the X-axis direction positive side end (one end in the width direction) of the panel main body 20. The first L-shaped member 41 has one piece 41a protruding from the X-axis direction positive surface (one side end surface 20A) of the panel main body 20, and another piece 41b fixed to the one side end surface 20A. The second L-shaped member 42 is provided along the outdoor side of the X-axis direction negative side end (the other end in the width direction) of the panel main body 20. The second L-shaped member 42 has one piece 42a protruding from the surface (other end surface 20B) on the X-axis direction negative side of the panel main body 20, and another piece 42b fixed to the other end surface 20B. One side 41a of the first L-shaped member 41 and one side 42a of the second L-shaped member 42 are located closer to the indoor side than the surface of the panel main body 20 on the negative side in the Y-axis direction (the outdoor side). Furthermore, the other piece 41b of the first L-shaped member 41 and the other piece 42b of the second L-shaped member 42 have different lengths in the Y-axis direction. For example, in this embodiment, the other piece 41b of the first L-shaped member 41 has a longer length in the Y-axis direction than the other piece 42b of the second L-shaped member 42. Note that the other piece 42b of the second L-shaped member 42 may be configured to have a longer length in the Y-axis direction than the other piece 41b of the first L-shaped member 41.

[0031] Multiple exterior wall panels 100 are arranged in the X-axis direction (width direction of the exterior wall panels 100) so as to form the same plane, and as shown in Figure 1, adjacent exterior wall panels 100 are connected and joined at joints A to form the exterior wall 1000. 1 and 2, the spacer member 30 of one of the adjacent exterior wall panels 100 is abutted against the vertical frame member 21 of the other exterior wall panel 100. The spacer member 30 and one piece 41a of the first L-shaped member 41 of one of the adjacent exterior wall panels 100, and the piece 42a of the second L-shaped member 42 of the other of the adjacent exterior wall panels 100, are arranged side by side in the Y-axis direction (indoor / outdoor direction). This makes it possible to form joints (joint bottoms) between adjacent exterior wall panels 100 simply by arranging the exterior wall panels 100 adjacent to each other in the width direction. In other words, it is possible to form joints more easily.

[0032] Then, a first fixing member 400 is inserted from the exterior side through one piece 41a of the first L-shaped member 41 and one piece 42a of the second L-shaped member 42, and is inserted into and fixed to the spacer member 30. The first fixing member 400 is, for example, a general-purpose screw such as a tex screw.

[0033] In addition, the spacer member 30 and the panel main body 20 of one of the adjacent exterior wall panels 100 are fixed to the panel main body 20 of the other exterior wall panel 100 by a second fixing member 500. The second fixing member 500 is a general-purpose screw or the like. Specifically, the second fixing member 500 is inserted from the surface of the panel body 20 of one of the adjacent exterior wall panels 100 (from the indoor side) into the spacer member 30 of one exterior wall panel 100 and the panel body 20 of the other exterior wall panel 100. Moreover, the second fixing member 500 is inserted from the surface of the panel body 20 of the other exterior wall panel 100 (from the indoor side) into the spacer member 30 and the panel body 20 of one exterior wall panel 100. As described above, the second fixing member 500 is inserted obliquely into the exterior wall panel 100, and appears to intersect in an X shape when viewed from the Z-axis direction, as shown in Figures 1 and 2. This ensures sufficient bonding strength between adjacent exterior wall panels 100. As described above, the exterior wall panels 100 adjacent to each other in the X-axis direction are joined together.

[0034] The interior material 200 is formed of gypsum board or the like. 1 and 2, the interior material 200 is provided in contact with the surface of the exterior wall panel 100 on the positive side in the Y-axis direction.

[0035] As shown in FIG. 2, the joint member 300 is filled or inserted between the panel bodies 20 of the adjacent exterior wall panels 100 from the outdoor side. Specifically, the joint member 300 is filled or inserted into a space surrounded by the end panel portion 121 and the first L-shaped member 41 of one of the adjacent exterior wall panels 100, and the end panel portion 122 and the second L-shaped member 42 of the other exterior wall panel 100. As a result, the head of the first fixing member 400 is embedded in the joint member 300. Therefore, no gaps are generated on the surfaces on the negative side in the Y-axis direction (surfaces facing the outdoors) between adjacent exterior wall panels 100, making it possible to prevent water and the like from entering the indoor side from the outdoors side.

[0036] A building equipped with the exterior wall 1000 of this embodiment is constructed using a panel construction method in which building components such as walls, floors, and roofs are panelized in advance at a factory, and these panels, which are panel bodies 20 (wood panels for construction), are assembled at the construction site. However, this is not limited to this, and the building may also be constructed using conventional frame construction, wall construction, two-by-four construction, etc.

[0037] [2. Installation Instructions] Next, a method for joining the exterior wall panels 100 will be described. FIG. 4 shows a flow chart of the joining method.

[0038] In the joining method, first, a plurality of exterior wall panels 100 are lined up in the X-axis direction so as to form the same plane. Then, the spacer member 30 and one piece 41a of the first L-shaped member 41 of one of the adjacent exterior wall panels 100 and the piece 42a of the second L-shaped member 42 of the other of the adjacent exterior wall panels 100 are arranged side by side in the Y-axis direction (indoor / outdoor direction) (Step S1). Step S1 is a panel arrangement step.

[0039] Next, the spacer member 30 and one piece 41a of the first L-shaped member 41 of one of the adjacent exterior wall panels 100 arranged side by side in step S1, and one piece 42a of the second L-shaped member 42 of the other exterior wall panel 100 are fixed together with the first fixing member 400. A plurality of first fixing members 400 are provided at predetermined intervals in the height direction (Z-axis direction) of the panel main body 20. This temporarily fixes adjacent exterior wall panels 100 (step S2). Step S2 is a first fixing step.

[0040] Next, the spacer member 30 and the panel main body 20 of one of the adjacent exterior wall panels 100 are fixed to the panel main body 20 of the other exterior wall panel 100 by the second fixing member 500. A plurality of second fixing members 500 are provided at predetermined intervals in the height direction (Z-axis direction) of the panel main body 20. This completes the fixation of adjacent exterior wall panels 100 (step S3). Step S3 is the second fixing step.

[0041] Next, the interior material 200 is attached to the exterior wall panel 100 from the positive side in the Y-axis direction with fixing members such as screws (step S4). Next, the joint member 300 is filled or inserted between the panel bodies 20 of the adjacent exterior wall panels 100 from the exterior side (step S5), and the joining of the exterior wall panels 100 is completed.

[0042] [3.Effects] As described above, the joint structure of the exterior wall panel 100 of this embodiment is a joint structure of exterior wall panels 100 adjacent in the width direction (X-axis direction), and the exterior wall panel 100 includes the panel main body 20, the spacer member 30 provided along the indoor side of one end portion of the panel main body 20 in the width direction, the first L-shaped member 41 provided along the outdoor side of one end portion of the panel main body 20 in the width direction, one piece 41a protruding from one end surface 20A of the panel main body 20 and the other piece 41b fixed to the one end surface 20A of the panel main body 20, and the second L-shaped member 41 provided along the outdoor side of the other end portion of the panel main body 20 in the width direction, one piece 42a protruding from the other end surface 20B of the panel main body 20 and the other piece 42b fixed to the other end surface 20B of the panel main body 20. and an L-shaped member 42, one piece 41a of the first L-shaped member 41 and one piece 42a of the second L-shaped member 42 being located indoors relative to the outdoor side of the panel body 20, the spacer member 30 and the piece 41a of the first L-shaped member 41 in one of the adjacent exterior wall panels 100 and the piece 42a of the second L-shaped member 42 in the other of the adjacent exterior wall panels 100 being arranged side by side in the indoor-outdoor direction (Y-axis direction) and fixed by a first fixing member 400, and the spacer member 30 and the panel body 20 in one of the exterior wall panels 100 and the panel body 20 in the other exterior wall panel 100 being fixed by a second fixing member 500. According to this, by simply arranging the exterior wall panels 100 adjacent to each other in the width direction, a joint (joint bottom) can be formed between adjacent exterior wall panels 100 using the spacer member 30, the first L-shaped member 41 and the second L-shaped member 42, making it possible to form the joint more easily. In addition, by fixing the first L-shaped member 41 and the second L-shaped member 42 of adjacent exterior wall panels 100 to the spacer member 30 with the first fixing member 400, and further fixing the adjacent exterior wall panels 100 with the second fixing member 500, the adjacent exterior wall panels 100 can be joined more firmly. Therefore, adjacent exterior wall panels 100 can be joined more easily and more firmly.

[0043] In the joining structure of the exterior wall panel 100 of this embodiment, the first fixing member 400 and the second fixing member 500 are general-purpose screws. This allows adjacent exterior wall panels 100 to be joined together without using any dedicated fixing members. Therefore, the exterior wall panels 100 can be joined more easily.

[0044] Furthermore, in the joining structure of the exterior wall panels 100 of this embodiment, the second fixing member 500 is inserted from the surface of the panel main body 20 of one exterior wall panel 100 into the spacer member 30 and the panel main body 20 of the other exterior wall panel 100, and the second fixing member 500 is inserted from the surface of the panel main body 20 of the other exterior wall panel 100 into the spacer member 30 and the panel main body 20 of one exterior wall panel 100. According to this, the second fixing member 500 is inserted obliquely into the exterior wall panel 100, and appears to intersect in an X shape when viewed vertically. Therefore, the bonding strength between adjacent exterior wall panels 100 is sufficient.

[0045] In the joining structure of the exterior wall panel 100 of this embodiment, the second fixing member 500 is inserted from the indoor side. This allows the work of inserting the second fixing member 500 to be carried out from the indoor side. Therefore, the work of inserting the second fixing member 500 can be carried out regardless of the outdoor environment, and the burden on the worker can be reduced.

[0046] Furthermore, in the joint structure of the exterior wall panel 100 of this embodiment, the exterior wall panel 100 is provided with an exterior material 10 provided on the outdoor surface of the panel main body 20, and one widthwise end portion (end panel portion 121) of the exterior material 10 is overlapped on the other piece 41b of the first L-shaped member 41, and the other widthwise end portion (end panel portion 122) of the exterior material 10 is overlapped on the other piece 42b of the second L-shaped member 42. According to this, by filling the joints between adjacent exterior wall panels 100 with the joint member 300, no gaps are generated on the outdoor surfaces between adjacent exterior wall panels 100. Therefore, it is possible to prevent water and the like from entering the indoor side from the outdoor side.

[0047] In addition, in the joint structure of the exterior wall panel 100 of this embodiment, a joint member 300 is filled between the first L-shaped member 41 and the second L-shaped member 42. According to this, by filling the joints between adjacent exterior wall panels 100 with the joint member 300, no gaps are generated on the outdoor surfaces between adjacent exterior wall panels 100. Therefore, it is possible to prevent water and the like from entering the indoor side from the outdoor side.

According to this, by simply arranging the exterior wall panels 100 adjacent to each other in the width direction, a joint (joint bottom) can be formed between adjacent exterior wall panels 100 using the spacer member 30, the first L-shaped member 41 and the second L-shaped member 42, making it possible to form the joint more easily. In addition, by fixing the first L-shaped member 41 and the second L-shaped member 42 of adjacent exterior wall panels 100 to the spacer member 30 with the first fixing member 400, and further fixing the adjacent exterior wall panels 100 with the second fixing member 500, the adjacent exterior wall panels 100 can be joined more firmly. Therefore, adjacent exterior wall panels 100 can be joined more easily and more firmly.

[0049] Furthermore, in recent years, there has been a demand for the realization of a carbon-neutral society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and for the achievement of the SDGs (Sustainable Development Goals), and in the construction industry, efforts are being made to build buildings using wood, which has low carbon dioxide emissions. The exterior wall 1000 formed by the joint structure of the exterior wall panel 100 of this embodiment is partially made of wood, and therefore can contribute to the realization of a carbon-neutral society by promoting carbon neutrality and the achievement of the SDGs.
