SHEET FOR STAIRCASE AND CONSTRUCTION METHOD OF THE SAME AND STAIRCASE STRUCTURE

To provide a sheet for a staircase which can be constructed to a staircase having a nosing part easily.SOLUTION: A sheet 3 for a staircase is constructed at a tread part, a riser part and a nosing part of a staircase which includes the tread part, the riser part and the nosing part provided in a frontward protrusive manner between the tread part and the riser part. The sheet includes a soft body layer 31, and a fiber reinforcement layer 32 laminated on a rear surface or inside of the body layer 31. In the region corresponding to an upper external corner part of the nosing part, in a region corresponding to a lower external corner part and in a region corresponding to a lower internal corner part, a linear notch 7 for dividing the fiber reinforcement layer 32 is formed in the width direction.SELECTED DRAWING: Figure 6 【課題】 段鼻部を有する階段に容易に施工できる階段用シートを提供する。【解決手段】 踏み面部、蹴込み面部、及び前記踏み面部と蹴込み面部の間において前方に突設された段鼻部を有する階段の前記踏み面部、段鼻部及び蹴込み面部に施工される階段用シート３であって、柔軟な本体層３１と、前記本体層３１の裏面又は内部に積層された繊維補強層３２と、を有し、段鼻部の上出隅部に対応する領域、下出隅部に対応する領域及び下入隅部に対応する領域に、前記繊維補強層３２を分断する線状切込み７が幅方向に形成されている。【選択図】 図６
