PROBLEM TO BE SOLVED: To provide a roof frame structure capable of widely securing a lower side space of a rafter member.SOLUTION: A roof frame structure is provided for forming a framework of a hipped roof or a gable roof by supporting a plurality of rafter members 21 in an inclined shape by a roof truss frame 4 provided in an upper part of a lower structure 3. The roof truss frame 4 comprises purlin beams M1-M6 provided in a horizontal shape and a takeout beam M10 projecting in a horizontal shape from the purlin beam M or a post. A lower part of the rafter member 21 is supported by the lower structure 3, and a midway part of the rafter member 21 is supported by the purlin beams M1-6 or the takeout beam M10. The rafter member 21 is installed in the lower structure 3 and the purlin beams M1-M6 or the takeout beam M10 in a state of projecting an upper part of the rafter member 21 obliquely upward in a cantilever state from the purlin beams M1-M6 or the takeout beam M10.SELECTED DRAWING: Figure 4 |
