Groundsill connectors

(Dodai shiguchi)

(1) Housed dovetail (ari otoshi)

A dovetail is carved on half of the depth of one member. A rectangular mortise runs through the depth of the second member immediately behind the mortise for the dovetail. A column with a simple tenon may complete the assembly. A draw pin secures the column to the groundsill. The length of the pole tenon on the column equals the depth of the groundsill. Thus, even if the groundsill rots, the column will stand firm. This often happen since the groundsill is usually made of softwood and the column made of hardwood.

(2) Rabbeted tenon and mortise (konc hozo sashi)

This joint is useful to assemble corner groundsills. The male sill (B) has an eccentric tenon at the end. The female (A) has a mortise cut throughout. After assembly, a wedge is pounded through a slot in the tenon, locking the members together. If there is enough room left at the end of member A (distance a— H/2), a column can be connected over the joint using a stub tenon.

(3) Corner miter tenon (sumitome hozo sashi)

This joint also connects corner groundsills but is more attractive than the previous one. A tongue and groove on the inside ensure rigidity while a panel on the outside gives the joint a cleaner look. The outside scam is located at the corner making the assembly appear to have been made out of a single piece of wood. The tapered panel at the end of member B (male) reduces the distance (a) left at the end of member A (female). For thus reason, a trapezoidal stub tenon is preferred to connect a column over the corner joint.
