To provide a staircase unit that can reduce the work of handling ventilation ducts at the construction site of equipment placed in the underfloor space and improve workability.SOLUTION: A staircase unit 10 incorporated in a unit building 1 in which a heat source machine 6 that requires intake and exhaust is installed in an underfloor space 5, includes: a staircase portion 12; a central wall 11 and an outer peripheral wall 13 that support the staircase portion 12; a below-staircase space 20 formed below the staircase portion 12 surrounded by the staircase 12, the central wall 11 and the outer peripheral wall 13; and a duct 30 placed in the below-staircase space 20. Further, in the duct 30, one end portion 30a is inserted into a first through hole 7 formed in a floor plate 3e and protrudes into the underfloor space 5, and another end portion 30b is inserted into an opening 17e of one end portion 17c of a connection duct 17 provided in a second outer peripheral portion 15 of the outer peripheral wall 13 and communicates with the outside of the below-staircase space 20.SELECTED DRAWING: Figure 2
【課題】床下空間に配置された機器の施工現場での通気ダクトの取り回し作業を軽減し、施工性を向上させることができる階段ユニットを提供すること。【解決手段】床下空間５に吸排気が必要な熱源機６が設置されたユニット建物１に組み込まれる階段ユニット１０であって、階段部１２と、階段部１２を支持する中央壁１１及び外周壁１３と、階段部１２と中央壁１１及び外周壁１３に囲まれて、階段部１２の下方に形成された階段下空間２０と、階段下空間２０に配置されたダクト３０と、を備えている。そして、ダクト３０は、一端部３０ａが床板３ｅに形成された第１貫通孔７に差し込まれて床下空間５に突出し、他端部３０ｂが外周壁１３の第２外周部１５に設けられた接続ダクト１７の一端部１７ｃの開口１７ｅに差し込まれて階段下空間２０の外部に連通する。【選択図】図２
