MASTER JOINERY & KIGUMI (木組)

Interlocking Wood Mechanics

Discover why traditional Japanese joinery dissipates earthquake energy and outlasts modern metal screws and chemical adhesives.

Locked Structure (0%)35% Exploded SeparationFully Disassembled (100%)

Beam-to-Beam Longitudinal Splicing金輪継ぎ

Kanawa-tsugi (Blind Scarf Joint with Locking Key)

Magnitude 8.2 Dynamic Energy Dissipation

One of the most revered joints in Japanese temple architecture. Connects two heavy structural beams seamlessly, resisting bending moment, torsion, and seismic tension without a single screw or bolt.

Load Capacity185 kN

Fastener Hardware0% Nails / 0% Glue

Mechanical Advantage:Tension and shear forces cause the interlocking teeth to compress tighter together under load.
