The purpose for the study of the Hirakake Komisen Tsugi joint was to become familiar with the many Japanese joints and joinery involved in wooden structures and wooden CLT buildings.

History

Hirak ake Komisen Tsugi falls within the Tsugi (splice) family which is often used to replace portions of rotted posts and beams. "平掛け込み 栓継ぎ" aka the Hirakake joint uses a tenon (a at non-angled tenon in particular). In a general sense, the Hirakake Komisen Tsugi joint is suitable for replacing beams or portions of beams, especially between xed supports where a lot of working space is unavailable.
