STAIR AND CONSTRUCTION METHOD THEREOF
To allow selection of a construction procedure according to the necessity of a construction site so that a lowermost riser 18 in the stairs S can be inserted into the riser insertion groove 8 of the side plate 1 from either of upper and lower sides.SOLUTION: A lowermost riser insertion groove 8A is a wide groove having a groove width such that a lowermost riser 18A can form an inclined posture inclined with respect to a vertical surface. By both of an upper insertion path R1 from a rear open end part 5 of a lowermost tread insertion groove 4A through the lowermost tread insertion groove 4A into the lowermost riser insertion groove 8A in which the upper-end part communicates with the lowermost tread insertion groove 4A, and a lower insertion path R2 from a lower open end part 10 of the lowermost riser insertion groove 8A to the inside of the lowermost riser insertion groove 8A, the lowermost riser 18A can be inserted into the lowermost riser insertion groove 8A while being in an inclined posture.SELECTED DRAWING: Figure 5
【課題】階段Ｓにおける最下段の蹴込み板１８を側板１の蹴込み板挿入溝８に対し上下両側のいずれからでも挿入可能として、それらの施工手順を施工現場の必要に応じて選択できるようにする。【解決手段】最下段蹴込み板挿入溝８Ａは、その内部で最下段の蹴込み板１８Ａが鉛直面に対して傾斜した傾斜姿勢を形成し得る程度の溝幅を有する広幅溝とし、最下段の蹴込み板１８Ａが最下段蹴込み板挿入溝８Ａ内に対し、最下段踏板挿入溝４Ａの後側開放端部５から該最下段踏板挿入溝４Ａを経て、上端部が最下段踏板挿入溝４Ａに連通する最下段蹴込み板挿入溝８Ａ内に至る上側挿入経路Ｒ１と、最下段蹴込み板挿入溝８Ａの下側開放端部１０から該最下段蹴込み板挿入溝８Ａ内に至る下側挿入経路Ｒ２との両方により傾斜姿勢となりながら挿入可能とする。【選択図】図５
