As shown in FIG. 5, an engagement plate 65 at the lower end of the outer wall panel 10 that is suspended from above is engaged with the upper end inner surface of the outer wall panel 10 that is built in advance under the lower side. The upper and lower outer wall panels 10 are engaged with each other. By engaging in this way, the upper and lower outer wall panels 10 are allowed to move in the out-of-plane direction while being allowed to move in the in-plane direction. That is, the upper and lower outer wall panels 10 regulate the movement in the out-of-plane direction. Here, since the position of the upper end of each outer wall panel 10 is determined by the hanging hardware 30, the position of the lower end of the upper outer wall panel 10 is also determined.

Thus, the outer wall panel mounting structure of the embodiment is completed.
In this mounting structure and mounting method, the hanging hardware 30 provided on the upper portion of the outer wall panel 10 is engaged with the receiving hardware 20 provided on the housing 1 of the building, and at the same time, the lower end of the outer wall panel 10 is first placed on the lower side. Since the outer wall panel 10 can be fixed to the housing 1 of the building simply by meshing with the upper end of the built-in outer wall panel 10 via engagement hardware (the engagement plate 60 and the base plate 32 are equivalent), the outer wall panel 10 The mounting work can be simplified.

  Further, since the lower engagement hardware 60 only has a function of restricting the relative movement of the upper and lower outer wall panels 10 in the out-of-plane direction, the configuration can be simplified and the cost can be reduced. Further, the lower end of the outer wall panel 10 can be engaged only by hanging from above, and the upper hanging hardware 30 and the receiving hardware 20 can be engaged only from the top of the beam 1A of the housing 1. Therefore, it is also possible to perform installation work at a portion where hands cannot be reached such as the double wall portion of the outer wall of the wife as in the embodiment.
