竪穴区画

塩崎君達の設計は毎度法を上手くかいくぐる。コンクリート3階建の耐火建築物には竪穴区画を設けないといけない。しかし階段や間仕切り壁を木にして準耐火建築物と見做されると竪穴区画は不要となり上下の連続した空間が可能となる。

Shiozaki’s designs always go through the law well. A fire resisting division through pit section must be provided in a three-story concrete fireproof building. However, if the stairs and partition walls are made of wood and are regarded as a semi-fireproof building, the fire resisting division through pit section becomes unnecessary and a continuous space above and below becomes possible.
