Manufacture of drift pins and boards made from bamboo fi ber for timber structures

In timber structures which are between housing and heavy timber structure, nails, drift pins, bolts and steel plates are typically used. A law concerning construction recycling was passed in Japan in 2002 which placed specific restrictions on the dismantlement of buildings and housing. As a result, the dismantlement of buildings containing wood, wood-based materials and metallic joint tools has become complicated. Dismantlement is much simpler if joint materials and all building materials are wood-based. In addition, wood-based materials, because they are lightweight, are more earthquake resistant. Bamboo, because it contains high-strength fiber and grows quickly, has received attention as a lingo-cellulosic material.
