RAINWATER GUIDE STAIR, PRECAST CONCRETE BLOCK AND BLOCKS FOR RAINWATER GUIDE STAIR
To provide a rainwater guide stair, a precast concrete block and a block for rainwater guide stair, capable of effectively draining water without attaching a separate member to a stair and capable of efficiently draining rainwater by reducing the possibility that rainwater flows like a waterfall.SOLUTION: A rainwater guide stair 1 is provided with a step nose part 10 formed in a convex curved surface, a riser plate part 30 which is communicated from the step nose part 10 and is formed to be inclined backward from the upper side to the lower side, a tread surface 20, and a drain part 40 which is formed lower than the tread surface in the vicinity of the riser part or the riser part of the tread surface 20, and the boundary between the drain part 40 and the riser plate part 30 is formed of a concave curved surface.SELECTED DRAWING: Figure 1
【課題】本発明は、階段に別の部材を取付けることなく、効果的に排水可能であり、かつ雨水が滝のように流れる可能性を低減して効率よく排水可能な雨水誘導階段、プレキャスト型コンクリートブロック及び雨水誘導階段用ブロックを提供すること。【解決手段】本発明にかかる雨水誘導階段１は、凸状の曲面に形成されている段鼻部１０と、前記段鼻部１０から連通し、上方から下方に向かって後方に傾斜して形成されている蹴込板部３０と、踏面２０と、前記踏面２０の蹴込部又は蹴込部近傍に、前記踏面より低く形成された排水部４０と、を備え、前記排水部４０と蹴込板部３０との境界は、凹状の曲面で形成されていることを特徴とする。【選択図】図１
