In the conventional eaves side roof unit described above, the eaves portion is also formed integrally with the main body side of the roof in a non-separable manner, and the following problems have been pointed out. In other words, since the size of the unit is limited by the maximum loading size of the transportation vehicle, it may not be possible to integrally install eaves decorative materials, gutter receiving materials, etc. There is no choice but to install it during construction. In addition, it is necessary to prepare a plurality of types of roof units due to the difference in the eaves size, which increases the inventory amount.

The present invention has been made in view of the above circumstances, and it is possible to reduce the number of on-site construction man-hours and improve the transportation efficiency, and it is possible to smoothly cope with the difference in the eaves protruding size, and further It is an object of the present invention to provide an outer wall panel with an eaves, a building unit and an assembling method of an eaves which can easily cope with an increase in the number of types.

[0007]

In order to solve the above-mentioned problems, in the outer wall panel according to claim 1, the base end of the eaves panel which constitutes the roof eaves is turned up and down by the hinge hardware at the upper end. It is characterized by being movably attached.

A building unit according to a second aspect is characterized in that the outer wall panel according to the first aspect is erected on a side edge portion of a floor panel.

Further, in the method of assembling the eaves according to claim 3, after the building unit according to claim 2 is installed, an eavesless roof unit is installed on the upper part of the building unit, and the eaves panel is lifted to raise the roof. It is characterized by connecting with a unit.

[0010]

Since the eaves panel is attached to the outer wall panel having the above-mentioned structure with the hinge hardware, the unit size can be reduced by folding the eaves panel. Therefore, even if the eaves decorative material, the gutter receiving material, or the like is attached to the eaves panel in advance, there is no obstacle in transportation. The same applies to the case where the building unit is constructed of the outer wall panels. Further, when assembling the building unit and the roof unit, the eaves can be assembled simply by lifting the eaves panel and connecting it to the roof unit without eaves.
