An opening 96 such as a window is provided on the outer wall 92 above a joint 95 between the outdoor side surface of the outer wall 92 and the inclined surface 97 of the overhanging roof unit 93. In such a unit-type building 90, waterproofing of the joint portion 95 is performed after assembling on site to prevent intrusion of rainwater or the like.

[0003]

However, in such a unit-type building 90 having a conventional overhanging roof,
Since the outdoor side surface of the outer wall 92 and the sloping surface 97 of the overhanging roof unit 93 are not flat, the waterproof structure of these joints 95 becomes complicated. In addition, since the number of complicated operations on the site increases, there has been a problem that the features of the unit-type building, in which only simple assembly is performed, cannot be fully utilized on the site.

On the other hand, in a unit-type building 90, a joint portion 95
There was a problem that the opening 96 could not be made large due to the presence of. In other words, in the case of the southern surface, there is a high demand for making the opening 96 large, but such a demand cannot be realized due to the restriction that the joint portion 95 cannot be extended or expanded downward. Was. In particular, since the joint portion 95 is a waterproof joint having a complicated fit as described above, a part of the outdoor side surface of the nearby outer wall 92 is occupied by waterproof treatment, and this is The restrictions on extension and expansion were further increased.

[0005] Further, since the window or the like as the opening 96 is often a standard product, it is not possible to set the dimensions freely. If you choose a possible one, the opening 96
Had the problem of becoming smaller.

[0006] It is an object of the present invention to provide such an exterior wall on the outdoor side.
