KEY WORD :@architecture / general terms

Also called *agokaki äGŒ‡, agokake äGŠ|. A cogged right-angled joint. Two timbers cross each other at right angles: shallow notches are cut on each side of the lower beam running parallel to the beam length, leaving an uncut section in the center of the beam. The upper beam, which is laid across the under one at a 45K angle, has only one dadoed cut at right angles to its length. The cut is of sufficient depth to allow a snug fit into the notches on the lower beam. For further strengthening, large mortises can be cut into the centers of each part of the joint and connected with a heavy pin. When the beams are joined the pin cannot be seen. This joint is used for cantilevers. Variants of this joint include: when only the upper beam has a dadoed cut at right angles to its length and is made to fit over an unnotched under beam. This joint is called watarikaki “nŒ‡; when the top and bottom beams are cut with a dovetail *ari ‹a, joint on one side and the usual cogged, rectangular joint on the opposite side. This joint is called watariago arikake “näG‹aŠ|. These joints are common in roof framing of folk dwellings in the transverse beam *koyabari ¬‰®—À, and in the eave purlin *nokigeta Œ¬Œ…. These joints are also used in the corner logs azegi Z–Ø, of the style storehouses *azekura Z‘q; and in the joining of transverse beams and purlins in temple construction.
