To provide a roof truss structure allowing diagonal members placed on various positions to be aligned to a reference height and production work for angle rafters and valley rafters to be reduced for a sloped roof with corner ridge parts and trough parts.SOLUTION: A roof truss structure 2 comprises: an angle rafter 3 in an allow wing shape in a sectional view in which an upper surface 31 and a lower surface 32 are formed in a crest shape with a top point of a center in a width direction; a valley rafter 4 formed by inverting the angle rafter 3 upside down; a plurality of rafter members 5 arranged with spaces in a horizontal direction and obliquely along a pitch of a roof; a long lateral frame member 6 orthogonal to the plurality of rafter members 5 to support at least the plurality of rafter members 5 and the valley rafters 4 from thereunder; and a receiving plate member 8 arranged on upper surfaces 6a, 7a of each of vertical members 7 supporting the angle rafter 3 from thereunder to receive the angle rafter 3, the valley rafter 4 and the rafter members 5.SELECTED DRAWING: Figure 2
【課題】 隅棟部や谷部を有する勾配屋根において、各所に設置される斜材の基準高さを揃えるとともに、隅木材及び谷木材の制作手間を抑える小屋組み構造を提供する。【解決手段】小屋組み構造２は、上面３１及び下面３２が、幅方向の中心を頂点とする山型状に形成された断面視矢羽根型状の隅木材３と、隅木材３を上下反転させて形成された谷木材４と、水平方向へ間隔を開けて配置され、且つ、屋根勾配に沿って傾斜する複数の垂木材５と、複数の垂木材５に直交し、少なくとも複数の垂木材５と谷木材４とを下から支持する長尺な横架材６、及び隅木材３を下から支持する垂直材７のそれぞれの上面６ａ、７ａに載置され、隅木材３、谷木材４、垂木材５を受ける受け板材８と、を備える。【選択図】図２
