Shoei Yoh Hamura - Bamboo for UCHINO and NAIJU of Chikuho Town, Fukuoka

Shoei Yoh, Hamura

Both public facilities of shell dome and vault were made of reinforced concrete with woven bamboo molds: kept square grid for Naiju producing folds or pleats as stiffener on the other hand bamboo grid for Uchino was deformed according to the rise and width of concrete supporting posts without producing any fold, pleat or wrinkle. Bamboo of Naiju was a tensile structure temporaly until concrete was cured. On the contrary, Uchino is a compression structure of vault and dome shell. .
Both have got cantilevered roof: in case of Uchino, it works just like a tie bar of irregular vault with differing the width and rise according to required space.
Naiju provides cozy corner for children and openings as windows or an entrance.
These two community centers were built by the people of a community with their own bamboo.
