<p>PROBLEM TO BE SOLVED: To simplify the constitution of roof truss, make the working easier, improve the quality, shorten the assembling time, reduce working hours by shortening assembling time, and effectively utilize attic space. SOLUTION: The roof truss 1 is built with a plurality of raking beams 6 provided along the roof gradient so as to form a rigid frame structure with a roof truss 5, thereby creasing a predetermined strength and making a space inside. Also, the raking beams 6 have a predetermined interval in the direction of roof slope, and a plurality of rail members 7 are attached in almost horizontal direction. To these rail members 7, panel members 2 forming the roof surface are positioned and attached on the raking beams 6.</p> |
