211N1聖ステパノ学園中学校教室棟「森の中の教室」St. Stephen's Junior High School周囲の木々と呼応し教室を囲う集成材のV字柱V - shaped laminated wood columns enclose a classroom that acts in concert with the surrounding trees聖ステパノ学園は、大磯の丘陵地に位置する。敷地は30m程度の起伏がある木々に覆われた斜面であり、四季の移ろいを感じながら学習するスペースをテーマとして、高床式のスラブと集成材のV字柱による「森の中の教室」を実現した。屋根を支持するV字型に傾いた木柱は、コンクリートの床スラブと鉄骨造の屋根を繋ぐ。接合部はドリフトピン接合とし、柱を傾けることによって鉛直力と同時に水平力を支持する。柱脚部分は、床スラブに固定したスチールプレートを集成材で挟み込み、側面からドリフトピンと長ボルトで締め付けるディテールとし、簡潔で軽快な意匠により、木々に囲まれた教室の透明感のある雰囲気を演出している。(宮本 有祐)St. Stephen's School is located in a hilly region of the town of Oiso in Kanagawa Prefecture. The site is on a tree-covered slope with ups and downs that measure approximately 30 meters in height. The design theme was to create a space for learning in which students can sense the changing seasons. The result is a "classroom in the forest" made up of a floor slab on stilts and V-shaped laminated wood columns. The tilted V-shaped wooden columns supporting the roof connect the concrete floor slab with the steel roof. Drift pins are used to connect the joints, and tilting the columns enables the horizontal force to be supported at the same time as the vertical force. The detail work at the column base consists of steel plates fastened to the floor slab and clamped by the laminated wood, and fastened together from the side using drift pins and long bolts. The result is a clean, crisp design that gives a transparent atmosphere to the classroom surrounded by trees.
