<p>PURPOSE:To enable even such a roof unit as being adjacently set up in another roof unit equipped with a roof sash or the like to be set up so well in terms of operability. CONSTITUTION:A lifting nut 26 is attached to the outer side of channel steel 21 of a roof unit 4. Since this nut 26 is clamped to the outer side of the channel steel 21, a roof facing 23 is stickable to a range of up to a top end of the channel steel 21 at a factory, thus it is unnecessary to stick this roof facing 23 at the site, so that operability at the jobsite is well improvable.</p> |
