<p>PURPOSE:To execute assembly work efficiently and improve the strength of a structural body, by connecting roof struts to each other by the use of a chevron-shaped beam, to form a roof beam unit. CONSTITUTION:A pair of roof struts 2 provided with inclined eaves beam pieces 6 at the upper ends of strut pieces 5 are placed confronted with the eaves beam pieces 6, and are bridged between the tips of the eaves beam pieces 6, by connecting the tips of the ridge beam pieces 7 of chevron-shaped beams having the ridge beam pieces 7 inclined to both the sides of ridges, to the tips of the eaves beam pieces 6, and a roof beam unit E is formed. Then, a plurality of the roof beam units E arranged in parallel with each other are integrally combined with joint beams S, S1... for jointing roof beams B consisting of the eaves beam pieces 6 and the ridge beam pieces 7, and a roof framework unit F1 is formed and is erected on the horizontal beam upper-surface at the upper end of a structure main-body.</p> |
