Applicant:The Japanese Association for Conservation of Architectural
Monuments |

Reason for selection:
Extensive restoration
work of the torii gate of the captioned shrine, an important cultural property,
was carried out for the first time in roughly 70 years, and as part of the
work, seismic diagnosis was conducted through detailed structural survey and
construction analysis with a 3-D model. The diagnosis found that each torii
column had large hollows caused by decay and termites and that its pedestal had
marks of previous repairs. It was structurally weakened and was in need of
structural reinforcement.
Taking into
account a unique situation that the torii gate is located in the sea and is
constantly subjected to seawater, it has been decided to use SUS312L (NSSC270) with
its high seawater resistance and corrosion resistance for designing and making
horizontal bands to reinforce the previously-repaired parts and vertical bands to
press and support the hollowed parts.
The floating
and historically important torii gate, as a composing element of the
Itsukushima Shrine, a world heritage, is one of Japan’s symbols visited by many
people every year.
The use of SUS312L this time has enabled the applicant to make the torii-gate
more quake-resistant with stainless steel, while retaining its cultural
value., .
