The protruding portion 4 of the protruding corner member 2 has a wide portion 46 exposed on the surface side of one wall material 61 and a narrow portion 47 exposed on the surface side of the other wall material 62. In the present embodiment, the wide portion 46 is the other connecting portion 44, and the narrow portion 47 is the curved portion 45.

The wide portion 46 is located on the protruding corner side of the one-sided joint material 71 in the protruding portion 4, and the portion of the protruding corner member 2 located on the one-sided wall material 61 side of the wide portion 46 is the one-sided wall material 61 and the one-sided joint material 71. The outdoor side is covered by. In each of the protruding corner member 2 and the protruding portion 4, only the wide portion 46 is exposed on the surface side of the wall material 61.

The narrow portion 47 is located on the protruding corner side of the other joint material 72 in the protruding portion 4, and the portion of the protruding corner member 2 located on the other wall material 62 side of the narrow portion 47 is the other wall material 62 and the other joint. The outdoor side is covered with the material 72. In each of the protruding corner member 2 and the protruding portion 4, only the narrow portion 47 is exposed on the surface side of the other wall material 62.

The wide portion 46 (the other connecting portion 44) has a rectangular surface shape extending in the vertical direction when viewed from the surface side of the one wall material 61. The width of the wide portion 46 is constant over the entire length of the wide portion 46 in the vertical direction. The narrow portion 47 (curved portion 45) has a linear shape extending in the vertical direction when viewed from the surface side of the other wall material 62. The width of the narrow portion 47 is constant over the entire length of the narrow portion 47 in the vertical direction. The width of the narrow portion 47 is smaller than the width of the wide portion 46 (on the other hand, the connecting portion 43). Therefore, when the protruding corner structure 1 is viewed from the surface side of the other wall material 62, the area of the exposed portion (narrow portion 47) of the protruding corner member 2 is small, and the protruding corner member 2 is inconspicuous. In particular, when the surface of the wall material 61 faces the adjacent building or the parking lot side adjacent to the building, and the appearance is less likely to be seen than the surface of the other wall material 62, the outside corner The appearance of the structure 1 is very simple and excellent.

The construction of the protruding corner structure 1 is performed, for example, as shown below. First, the protruding corner member 2 is attached to the wall base 5. Next, the one wall material 61 and the other wall material 62 are attached to the wall base 5. After that, the one joint material 71 and the other joint material 72 are filled between the one wall material 61 and the protruding corner member 2 and between the other wall material 62 and the protruding corner member 2, respectively. As a result, the construction of the protruding corner structure 1 is completed. Since the protruding corner member 2 of the present embodiment is composed of one member, it is easy to construct.

Each of the one wall material side accommodating portion 41 and the other wall material side accommodating portion 42 of the protruding corner member 2 has wall material positioning portions 413 and 423 that can be used for positioning the wall materials 61 and 62. On the other hand, the wall material positioning portion 413 of the wall material side accommodating portion 41 is a one-sided wall material positioning portion that restricts the movement of the wall material 61, and the other wall material positioning portion 423 of the wall material side accommodating portion 42 is. , The other wall material positioning unit that regulates the movement of the other wall material 62. In the present embodiment, the one wall material positioning portion 413 is the bottom portion 410 of the one wall material side accommodating portion 41, and the other wall material positioning portion 423 is the bottom portion 420 of the other wall material side accommodating portion 42.

On the other hand, when the wall material 61 is attached to the wall base 5, the back surface of the wall material 61 is exposed along the outer surface of one fixed piece 31 of the protruding corner member 2, and the end surface of the wall material 61 on the protruding corner side is exposed. The corner member 2 is brought into contact with the one-wall material positioning portion 413 (specifically, the end portion of the bottom portion 410 opposite to the end portion to which the side wall portion 411 is connected). Thereby, the movement of the one wall material 61 to the wide portion 46 (the other connection portion 44) side can be restricted, and by attaching the one wall material 61 to the wall base 5 in this state, the one wall material 61 is predetermined. Can be placed in position.

When the other wall material 62 is attached to the wall base 5, the back surface of the other wall material 62 is exposed along the outer surface of the other fixed piece 32 of the protruding corner member 2 and the end surface of the other wall material 62 on the protruding corner side is exposed. The corner member 2 is brought into contact with the other wall material positioning portion 423 (specifically, the end portion of the bottom portion 420 opposite to the end portion to which the side wall portion 421 is connected). Thereby, the movement of the other wall material 62 to the narrow portion 47 (curved portion 45) side can be restricted, and by attaching the other wall material 62 to the wall base 5 in this state, the other wall material 62 is predetermined. Can be placed in position. Therefore, the wall materials 61 and 62 can be easily installed at predetermined positions in the horizontal direction. Further, the width of the joint 91 formed between the one wall material 61 and the wide portion 46 and the width of the joint 92 formed between the other wall material 62 and the narrow portion 47 can be made constant. Therefore, the appearance of the protruding corner structure 1 can be further improved.
