To provide a stairway structure in which layout freedom and design property can be improved while preventing rain water staying on a tread and inside a stairway.SOLUTION: A stairway structure comprises: a stairway 2; and a drain portion 3 which is provided at a vertically lower side of the stairway 2 and into which rain water falling onto the stairway 2 flows. The stairway 2 includes: a tread portion 5 forming a tread and having water permeability; and rain water guide portion 8 provided at a vertically lower side of the tread portion 5 and guiding rain water infiltrating the tread portion 5 to the drain portion 3. Single grain crushed stones 31, 82 are filled in the drain portion 3 and the rain water guide portion 8, and rain water flows through gaps in the single grain crushed stones 31, 82.SELECTED DRAWING: Figure 2
【課題】踏面や階段の内部などに雨水が溜まることを防止しつつ、設計の自由度や意匠性を向上させることができる階段構造を提供する。【解決手段】階段２と、階段２の鉛直方向下側に設けられて階段２に降った雨水が流れ込む排水部３と、を有し、階段２は、踏面を形成し、透水性を有する踏面部５と、踏面部５の鉛直方向下側に設けられ、踏面部５に浸透した雨水を排水部３に導く雨水誘導部８と、を有する。排水部３および雨水誘導部８は、単粒砕石３１，８２が充填され、単粒砕石３１，８２の隙間を雨水が流れるように構成されている。【選択図】図２
