dashigeta　出桁

KEY WORD :　architecture / general terms

1　Also called *gagyou 丸桁 or gangyou. A round eave purlin that is supported by stepped bracket complexes *tokyou 斗きょう to bear the weight of extended eaves *noki-no-de 軒の出. Used in the 7c and 8c. The bracket complex varies from a simple, one-step bracket complex *degumi 出組, extended from the wall of the building up, to a six-step complex *mutesaki tokyou 六手先斗きょう. The dashigeta may receive added support from two more bracket complexes stacked one above the other on each tail rafter *odaruki 尾垂木. The lower bearing block supports a bracket arm called *hakarihijiki 秤肘木, with bearing blocks on each end giving it a balanced appearance. Another bearing block, placed on the tail rafter, carries a bracket arm on which three bearing blocks are set. A bracket arm called *sanehijiki 実肘木 is inserted into these bearing blocks and directly receives the dashigeta. Also read degeta. See *keta 桁. 2　A simple gate that has purlins parallel to the ridge *munagi 棟木. These purlins are also called dashigeta. They are supported by a short transverse beam called *udegi 腕木 or udegeta 腕桁. A simple bracket arm *hijiki 肘木, is often placed beneath it for additional support. See *kidomon 木戸門.
