Claims (1)

[Scope of Claim for Utility Model Registration] (1) A slope plate 3 in the shape of a flat plate to be placed on a slope of an embankment, etc. and a tread plate 5 in the shape of a flat plate with a substantially horizontal top surface separated by a required interval. The pillars 6,
It is a stair block formed in such a way that a through hole 7 for drainage is formed between the columns 6 and 6, which penetrates in the front and back direction, and the support column 6 has a width L of the side surface 10 on the rear side.
is formed to be zero or relatively small at the rear end 11 of the side surface and to become larger toward the front, and the lateral width L1 at the front end of the rear side surface 10 is the maximum lateral width of the column side surface. In addition, when the front and rear end surfaces of the inclined slabs 3 are in contact with each other and the stair blocks are laid vertically, the front end side portion 2 of the tread 5 of the stair block located at the upper step
Reference numeral 1 refers to a stair block characterized in that the stair block is arranged so as to overlap the rear end side portion 22 of the tread 5 of the stair block located at the lower step at a required interval in the vertical direction. (2) A flat plate-shaped inclined plate 3 placed on a slope of an embankment, etc. and a flat plate-shaped tread plate 5 whose upper surface is approximately horizontal are connected together by a single support 6. It is a stair block consisting of a stair block, in which the side end surfaces 9 of the treads are in contact with each other and the stair block is connected from side to side, and a through hole 7 for drainage is formed between the supports in the front and back direction. The support column 6 has a width L of the side surface 10 on the rear side.
is formed to be zero or relatively small at the rear end 11 of the side surface and to become larger toward the front, and the lateral width L1 at the front end of the rear side surface 10 is the maximum lateral width of the column side surface. In addition, when the front and rear end surfaces of the inclined block 3 are in contact with each other and the stair blocks are laid vertically, the front and rear side portions 2 of the tread 5 of the stair block located at the upper step are
Reference numeral 1 refers to a stair block characterized in that the stair block is arranged so as to overlap the rear end side portion 22 of the tread 5 of the stair block located at the lower level at a required interval in the vertical direction. (3) A claim in which the upper surface of the rear end side portion of the tread plate 5 is an inclined surface 23 that slopes downward toward the rear.
Block described in (1) or (2).
