いる間詰めコンクリートである。<<Prior Art>> Stair blocks having an L-shaped cross section are conventionally used. FIG. 3 is a cross-sectional view of a staircase using L-shaped stair blocks 21. Reference numeral 20 indicates a slope foundation made of crushed stone 20a with concrete 20b placed on top, and reference numeral 27 indicates a filling space between the slope foundation 20 and the block 21. It is filled with concrete.
《考案が解決しようとする課題》
ところで、このような従来のＬ字形階段ブロツ
クでは、ブロツク下面に空隙ができ易く、ブロツ
ク下面が間詰めコンクリートとうまく密着しない
という問題がある。<<Problems to be Solved by the Invention>> However, in such conventional L-shaped stair blocks, there is a problem that voids are easily formed on the bottom surface of the block, and the bottom surface of the block does not adhere well to the filler concrete.
この考案は、この問題を解決することを目的と
する。 This invention aims to solve this problem.

とする。<Means for Solving the Problems> The stair block of this invention consists of a tread portion and a rising portion extending upward from the tread portion and on which the steps of the upper block rest. The present invention is characterized in that a notch is formed at a ridgeline portion where the lower surface of the footboard portion intersects with the back surface of the rising portion.
《実施例》
第１図に示すように、この考案の階段ブロツク
１は、Ｌ字形で、踏み板部２と、それから上に延
びている立ち上がり部３を有している。<<Embodiment>> As shown in FIG. 1, the stair block 1 of this invention is L-shaped and has a tread portion 2 and a rising portion 3 extending upward from the tread portion 2.
踏み板部２の下面に溝６が形成されており、積
み重ねたとき、下の段のブロツクの立ち上がり部
がこの溝に係合するようになつている。 A groove 6 is formed on the lower surface of the footboard portion 2, so that when stacked, the rising portions of the blocks on the lower level engage with this groove.
踏み板部２の下面と立ち上がり部３の背面が交
差する稜線部４は、部分的に切り欠かれ、２つの
ノツチ５が形成されている。 A ridgeline portion 4 where the lower surface of the footboard portion 2 intersects with the back surface of the rising portion 3 is partially cut out to form two notches 5.

ト７を打設する。このコンクリート７はノツチ５
からブロツクの下に流れ込み、空隙を埋める。 As shown in FIG. 2, during construction, a slope foundation 20 is made in the conventional manner, and blocks 1 are stacked on top of it so that the ridgeline portions 4 of the blocks are brought into contact with the slope foundation 20. When stacking blocks, filler concrete 7 is placed in the triangular space A between the back surface of the lower block and the slope foundation 20. This concrete 7 is notchi 5
It flows under the block and fills the void.

で、高い強度が得られる。 In the staircase thus completed, the filler concrete 7 is in close contact with the lower surface of the block 1 of each step and is difficult to peel off. Moreover, the filling concrete 7 is
Each stage is not separated, but is connected to each other through the notches 5 of the blocks 1 of each stage, resulting in high strength.

それぞれねじ込まれる。 In addition, several anti-slip grooves 8 are formed on the upper surface of the footboard portion 2. Two types of screw holes are formed on the back of block 1, screw hole 9
Bolts 11 are screwed into the holes 12 and anchor bolts 13 are screwed into the screw holes 12, respectively, to fasten the straps 10 that are connected to the adjacent blocks.

る。《Effects》 The stair block of this invention has a notch formed at the ridgeline where the back surface and the bottom surface intersect, and filler concrete can be poured from the notch between the block and the slope foundation. No voids are formed. In addition, high strength can be obtained because the filler concrete at each stage, which fills the gap between the block and the slope foundation, is integrated with each other through the notch.
