heijiku 幣軸

Also hezuke or henzuke 辺付. Thought to be a corruption of a term used in Shōsōin documents Shōsōin Shizaichō 正倉院資財帳. The frame-like arrangement placed on each side, or each side and across the top of, entrances to temple halls, pagodas, shrines, and aristocratic residences. The lintel at the top of the frame is attached from beneath to a non-penetrating tie beam uchinori nageshi 内法長押 (see *uchinorizai 内法材). The vertical framing parts are set on non-penetrating tie beams that are less thick than the usual type *han-nageshi 半長押. The door jamb *hōdate 方立 is attached to the heijiku, to which the door is then hung. Pivot hinges *hassō kanagu 八双金具 may be used to attach the doors to the door jamb. The edges of the heijiku are usually chamfered. If square posts are chamfered at a 45° angle, they are called *kirimen 切面. Other moldings, called *karadomen 唐戸面, are cut with a rounded center. A *kichōmen 几帳面 is a type of chamfer that frames the paneled doors of the Chinese style *sangarado 桟唐戸. The chamfer is cut at each corner to leave pointed spike-like protrusions.
