drift-boltとは 意味・読み方・使い方

To provide a joint structure of a wood structural member attaining an efficient and economical structural design as a result of easily and economically enhancing compressive strain strength which is local compressive strength of the wood structural member by providing a reinforcing member made of high strength wood of the same quality as the wood structural member, at a peripheral part of a hole for passing a drift pin or a bolt in the wood structural member.例文帳に追加

木質構造材におけるドリフトピン又はボルトを通す孔の孔周辺部に、木質構造材と同質の高強度木材製の補強材を設けて補強することにより、簡易かつ経済的に木質構造材の局所的な圧縮強度であるめり込み強度を高めることができ、その結果、効率的、かつ経済的な構造設計を実現できる木質構造材の接合構造を提供する。 - 特許庁
