<p>PROBLEM TO BE SOLVED: To reduce cost and the period of time for construction by sticking and making contact jointing surfaces together of both the jointing members of neighboring roof unit, and jointing them with a jointing means thereby jointing the roof units together in the peripheral direction. SOLUTION: A roof unit R having almost a fan shape in plan view is formed by rafter members 23, ring members and roof plates 21 constituting the frame. And in building a roof, jointing surfaces 27a of the jointing rafter members 27 of the rafter members 23 of mutually neighboring unit R are stuck and brought into contact and are jointed by a jointing means such as bolt and nut 28. And an end portion at the central portion side of the unit R is jointed to a ridge link through a joint bracket provided in one united body at the position corresponding to the rafter member 23 of the unit R. Also in the same manner, the unit Rs are sequentially jointed and the roof is built. By doing this, both the cost and the period of time for the work can be decreased.</p> |
