futanoki　二軒
KEY WORD :　architecture / general terms
　
A double row of rafters, called base refers and flying rafters, that appears beneath the eaves of a roof. The base rafters *jidaruki 地垂木, are common rafters that extend from the ridge *munagi 棟木, to the exterior where they support the eaves. The visible part under the eaves is often called an exposed rafter *keshou daruki 化粧垂木. A long beam *kioi 木負, is positioned on top of the base rafters in order to support the second or upper row of rafters called flying rafters *hien daruki 飛檐垂木. The direction of the flying rafters is often very slightly elevated. A curved beam that serves as an eave support *kayaoi 茅負, is placed on top of them to add further support to the extended eaves. In the Nara period, the base rafters were often circular while the flying rafters were square. Base rafters are sometimes called *oonoki 大軒 (big eaves), and flying rafters *konoki 小軒 (small eaves). Example: Kairyuuouji Saikondou 海竜王寺西金堂, Nara period.
