<p>PURPOSE:To improve the strength of a crossed section between the strut piece and eaves beam piece of a great bending load, and execute the assembly work of a roof framework unit efficiently, by providing the upper end of the strut piece with the eaves beam piece previously and integrally. CONSTITUTION:At the upper end of a strut piece 5, an inclined eaves beam piece 6 connected to the tip of the ridge beam piece 7 of a chevron-shaped beam having the ridge piece 7 with the tip inclined to both the sides of a ridge is integrally set. In this manner, the eaves beam piece 6 inclined to the upper end of the strut piece 5 is set previously and integrally. As a result, the assembly work of a roof framework unit is efficiently executed, and the strength of a structure can be improved.</p> |
