ROOF FRAME OF SLOPED ROOF
To provide a roof frame of a sloped roof which can prevent an interference between a setback beam disposed at a setback position of an external wall and a corner rafter beam, in a sloped roof in which an ascending beam perpendicular to an eaves edge line and a corner rafter beam (or a valley rafter beam) disposed at 45° angle in a plan view to an eaves edge line are installed so that an eaves side extended line of beam tops of an ascending beam and a corner rafter beam pass a slope reference point set to have a height equal to or lower than a beam top of an outer peripheral beam.SOLUTION: At a portion where a setback dimension of a setback beam to an outer peripheral beam is smaller than a first predetermined dimension, an eaves edge side end portion of a corner rafter beam is joined to the setback beam, and the corner rafter beam is omitted between the setback beam and the outer peripheral beam. As to a portion where the setback dimension is equal to or larger than the first predetermined dimension and equal to or smaller than a second predetermined dimension, a portion near the eaves edge of the corner rafter beam 23 is joined respectively to the outer peripheral beam 30 and the setback beam 33 in a divided state with the setback beam 33 interposed inbetween.SELECTED DRAWING: Figure 7
【課題】 軒先ラインに直交する登り梁と、軒先ラインに対して平面視４５度に配置される隅木梁（または谷木梁）とが、それらの梁天の軒側延長線を外周梁の梁天以下の高さに設定された勾配基準点を通るように架設される勾配屋根において、外壁のセットバック箇所に配置されるセットバック梁と隅木梁とが干渉するのを回避し得る勾配屋根の屋根架構を提供する。【解決手段】 外周梁に対するセットバック梁のセットバック寸法が第１所定寸法未満の部位では、隅木梁の軒先側の端部がセットバック梁に接合されて、セットバック梁と外周梁との間には隅木梁が省かれる。前記セットバック寸法が第１所定寸法以上、第２所定寸法以下の部位については、隅木梁２３の軒先近傍部分がセットバック梁３３を挟んで分割された状態で、外周梁３０および該セットバック梁３３にそれぞれ接合される。【選択図】 図７
