A description will be given of a staircase for slope arrangement using steps of the present invention that can adopt such a configuration example.

  FIG. 2 is a side view schematically showing the configuration of the slope arrangement staircase of the present invention. In the same figure, the staircase 20 comprised by connecting the some step 10 is shown, and the position of a slope is shown with an imaginary line. The staircase 20 shown in the figure has four steps, and is configured by connecting four steps 10 shown in FIG.

  The connection of step 10 is performed by inserting the pile part 13 fixed to the support part of another step into the through hole provided in the step part 11 of one step. For example, it connects by inserting the pile part 13 fixed to the support part of the step part used as the 2nd step in the through-hole of the step part 11 used as the 1st step (lowermost stage) of the stairs 20. Thus, the steps of the present invention can be connected without using bolts / nuts or screw nails. Moreover, since the step part, the support part, and the pile part are integrated as mentioned above, the operation | work of the step of this invention is easy. Therefore, the step of the present invention can reduce the time required for the connecting work, and the staircase of the present invention using the step can also reduce the time required for the connecting work.

  When connecting the steps, the distance between the step portion 11 of the first step and the step portion 11 of the second step is maintained at a certain value (the length of the support portion 12) or more. This is because the through-hole 11a, the pile portion 13 and the support portion 12 are appropriately dimensioned so that the through-hole 11a disposed in the stepping portion can insert the pile portion 13 and the support portion 12 cannot be inserted. It depends on what is set.

  The installation of step 10 is performed by inserting the step pile 13 into the ground. The stepped portion 11 of the installed step is supported by the support portion 12 at one end located on the valley side, and the other end located on the mountain side contacts the slope. As described above, in the step of the present invention, the tread portion, the support portion, and the pile portion are integrated, and it is not necessary to separately prepare a pile (for example, a steel bar). For this reason, the steps of the present invention can be easily installed and the time required for the installation work can be reduced, and the stairs of the present invention using the steps can be easily installed and the time required for the installation work can be reduced.

  As described above, the steps and stairs of the present invention can significantly reduce the time required for connecting and installing on the slope. Moreover, since the step and staircase of this invention install the pile part 13 fixed to the support part of the step in the ground, the place where the staircase is installed as in the case of installing the angle iron into the ground There are no restrictions. That is, the staircase can be installed not only when the ground of the slope is soft but also when it is strong.
