An example of the laying of the present invention will be described with reference to FIGS. FIG. 14 shows an indented stair-like upholstery block 1 which is laid out in an orderly manner, and consists only of an indentation-type stair-like upholstery block 1 having the same shape without shifting laterally. Therefore, the position of the indented portion 13 on the front surface 2 of the block forming the end of the stairs coincides with all the stairs, and a pattern of the same shape is repeated in each stair.

FIG. 15 shows a case in which only the indented stair-shaped upholstered block 1 is laid, but the block is laid out by half a size each time the stairs change. Therefore, the same pattern is repeated every other stage, and the upper and lower adjacent stages have a protruding portion in the lower stage if the joke is indented. In this case, it is necessary to lay a half-size block on the left and right ends of the laying surface and align the ends.

FIG. 16 shows a protruding step-like upholstered block 14.
Only the steps where only the steps are laid and the steps where only the steps of the bay-entry stair-shaped upholstery block 1 are laid are alternately laid on the adjacent upper and lower steps. Therefore, in this case, the protrusion 15 and the indentation 13
Are symmetrically opposed at the top and bottom.

In addition, although not shown as an example of laying,
Blocks that are adjacent to each other on the same level and are laid alternately in a protruding type and a bay type. It is laid by shifting it half a size horizontally between the adjacent upper and lower tiers. All adjacent blocks on the left, right, upper and lower tiers are laid alternately as projecting type and bay type. In addition, there are various laying methods, such as laying a projecting type and a bay type completely at random. These various laying methods have been made possible by the fact that the shapes of the side surfaces of the blocks that contact each other are all the same.

FIG. 17 shows, as shown in FIG. 16, a stage in which only the protruding step-like upholstered block 14 is laid and a stage in which only the step of the indented step-like upholstery block 1 is laid alternately in the adjacent upper and lower stages. In the embodiment in which the protruding step-shaped upholstery block 14 having the planting opening 16 is employed in the protruding step-shaped upholstery block 14, the uppermost step of the protruding stepped upholstery block 14 is planted. A small shrub is planted in the opening 16 for use, and a lawn is planted in the opening 16 for planting of the protruding step-like upholstered block 14 of the other steps. Whether a small shrub is planted or a lawn is appropriately adopted depending on the surrounding environment and the use of the slope. In addition, the step-like upholstery block can be decorated with flowers.

Further, in the step-like stretched blocks of the present invention, when the upper block and the lower block are shifted laterally by half a size, the protrusions and recesses of the upper block and the lower block are formed. Since it is arranged at the fitting position, the upper and lower stair-like stretched blocks can be laid laterally shifted by half a size.

Further, there are two types: an indented step-like sloping block in which the central part of the front surface is sunk backward, and a projecting-type step-like stiffening block in which the central part of the front surface projects forward.
Since the contact surfaces on each side have the same length, various combinations can be made by appropriately changing the combination of the protruding type and the indentation type of the horizontally adjacent step-like upholstery blocks and the step-like upholstery blocks overlapping the upper and lower stages. A staircase pattern can be formed, and a staircase-like pattern can be changed according to changes in the environment.
Layouts can be made in various combinations according to the use of the slope.

By adopting a step-like upholstery block having an opening for planting as appropriate, planting can be performed, and a upholstery block adapted to the natural environment can be laid.
Further, by doing so, the roots of the planting are stretched on the ground under the tension block, and the laying of the tension block can be further strengthened.

Since the front surface connected to the front end of the bottom surface from the front end of the step-like stretched block is retreated as it goes downward, the foot can be carried smoothly without climbing up and down the stairs and catching feet on the stairs. It is safe.

As described above, the step-like upholstered block according to the present invention can provide excellent effects not found in the conventional block.
