A piece 41a of the spacer member 30 and the first L-shaped member 41 in one of the adjacent exterior wall panels 100, which is located on the indoor side of the side surface, and the other of the adjacent exterior wall panels 100. A panel arrangement step of arranging one piece 42a of the second L-shaped member 42 in the exterior wall panel 100 in an indoor/outdoor direction (Y-axis direction), and a spacer member 30 and the first L-shaped member in one exterior wall panel 100. A first fixing step in which one piece 41a of the member 41 and one piece 42a of the second L-shaped member 42 on the other outer wall panel 100 are fixed by the first fixing member 400, and the spacer member 30 on one outer wall panel 100 and It has a second fixing step of fixing the panel body 20 and the panel body 20 of the other outer wall panel 100 using the second fixing member 500.
According to this, by simply arranging the exterior wall panels 100 adjacent to each other in the width direction, the spacer member 30, the first L-shaped member 41, and the second L-shaped member 42 create joints (joint bottoms) between the adjacent exterior wall panels 100. ), making it easier to form joints.
Further, the first L-shaped member 41 and the second L-shaped member 42 of the adjacent outer wall panel 100 are fixed to the spacer member 30 by the first fixing member 400, and further the adjacent outer wall panel 100 is fixed by the second fixing member 500. By fixing, adjacent exterior wall panels 100 can be joined more firmly.
Therefore, adjacent exterior wall panels 100 can be more easily and more firmly joined.

In addition, in recent years, there has been a need to realize a decarbonized society by promoting carbon neutrality, which reduces carbon dioxide emissions to virtually zero, and to achieve the SDGs (Sustainable Development Goals). Efforts are underway to make the building wooden, which produces less emissions. Since the outer wall 1000 formed by the joint structure of the outer wall panels 100 of this embodiment is partially made of wood, it can contribute to realizing a decarbonized society by promoting carbon neutrality and achieving the goals of SDGs.

Note that the embodiments to which the present invention is applicable are not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the present invention. For example, although the spacer member 30 in the above embodiment is bonded to the positive side surface of the panel body 20 in the X-axis direction with an adhesive or the like, the present invention is not limited thereto. They may be joined by a fixing member such as a screw.
