1.Stone based 'Orioki' frame

Stone based eOriokif frame is a Japanese traditional construction method using the traditional flexible joint and the building is cut off from the ground. Therefore, the building has seismic isolation.

Stone based eOriokif frame will slip on the stone when the big earthquake comes and the flexible joint will absorb the inner stress when the earthquake force a strong Lateral force,very Japanease way not 'against' but 'with' the 'NATURE'.
 

How to build 'Orioki' frame

'Setting the stones'

More than one hundred stones has been buried and the stones will act as the barrier between the EARTH and the man made Artifact.

'Notching a timber'
Notched timber joint in a Japanese traditional way.The top level of orthogonal beams are different to avoid concentrating internal defects.

'Building up the notched timbers'
Prepair frames in advance for each lines.
Pillars(Japanese cypress) stand directly on the stone.

Joint the assembled frames one by one.

Four beams are connected to form a single 'Keta' (digit).
Look at the detail of the joint of the beams.

œ Because we have a lot of rain here in Japan and a timber will get easy to be damaged when it wet, quick and smart work is very important!
