Japan Home Show Future Seed Award "Titanic Wins"

We received the Future Seed Award at the Japan Home Show held recently.
"Titanic"
A seismic joint for wooden houses using patented technology that follows wood shrinkage. In wooden houses, the joints can loosen over time due to wood shrinkage, gradually reducing seismic resistance. "Titanic" prevents this decline in seismic resistance. It uses an internal spring to pull the bolt and a magic ring to tighten it, reducing loosening. A next-generation joining hardware that withstands large forces with light tightening force.
[Judging Comments]
Japan's traditional wooden construction methods were designed to accommodate changes and displacements over time with skillful joints and connections. In modern times, these methods have been replaced by hardware, achieving strong rigidity while also addressing issues arising from the differences in material properties between metal and wood. Loosening of bolts due to wood shrinkage and vibrations is one such issue, and while there have been responses using spring nuts and washers, this product significantly enhances performance. The spring that follows wood shrinkage and the ring that suppresses the rotation of the bolt maintain the tightening force. Ensuring that the basic structural performance continues over time is the foundation of the architectural expression experienced through the ages. This product was highly evaluated as a component contributing to that. (Sotaro Yamamoto)
