<p>PURPOSE:To simplify the field work for constructing a prefabricated building and enhance water proofing property. CONSTITUTION:The frame 57 of a roof unit 10 has a projecting part 15 extending from an inclined beam 57A forming the frame 57 to the edge of a sheathing board 56, and the sheathing board edge part of the projecting part 15 has a hanging tool mounting part 16 to which a hanging bolt 55 can be spirally fitted. Since the hanging bolt 55 can be mounted to the frame 57 without passing through the sheathing board 56, a roof material 17 can be preliminarily stuck to the whole surface of the sheathing board 56 in factory, and the through- hole for the hanging bolt 55 is not required.</p> |
