Description

[Detailed description of the invention] (Industrial application field) This invention relates to an outdoor stair paving stone made of concrete in which natural stones, etc. are embedded, to be laid in outdoor parks, plazas, etc.

(Conventional technology) Conventionally, paving stones for this type of concrete stairs constructed outdoors were prepared by excavating the ground in a step-like manner on a slope in advance, laying a wire mesh on the step-like surface, and pouring the foundation concrete. After that, leveling mortar is laid on the staircase surface, and then stair paving stones with a rectangular cross section are sequentially laid to construct the stairs. However, in this case, the disadvantage is that it requires a lot of effort to form the foundation in the form of steps on the ground in advance, and the dimensions of the stair treads are formed separately depending on the slope and the number of steps, so there are many treads with different dimensions. There are drawbacks to building stairs.

(Problems to be solved by the invention) This invention improves each of the above-mentioned drawbacks.In outdoor stair paving stones, the width of the tread of the stair paving stones can freely expand and contract, making it difficult to construct. It would be very convenient if it could be adjusted when Furthermore, when constructing stairs, if the paving stones for the stairs can be easily laid on the sloped surface without constructing the base surface in a step-like manner, there is a convenient characteristic that the finishing can be carried out easily. However, there is currently no staircase that satisfies these points, and the appearance of one is desired.

This invention is proposed in order to meet the above-mentioned demands.

(Means for solving the problems) In order to solve all the above-mentioned problems, the outdoor stair paving stones of this invention have a horizontal tread and a vertical surface on the front side of the stair paving stone body, and the surface Natural stones of various colors and shapes are installed, and the lower surface of the stair paving stone body is formed with a bottom slope that presses against the mortar, and in front of the slope is a horizontal adjustment horizontal surface and a slope wall. By forming the tread, the width and angle of the tread can be easily changed to achieve the purpose.

(Example) Next, an example of this invention will be described with reference to a drawing. The stair paving stone body 1 is formed in an arbitrary longitudinal direction, and natural stones of various colors and patterns and shapes are embedded in the concrete surface. The treads and front part have been finished. The stair paving stone body 1 has a horizontal tread 2
and a front vertical surface 3 are formed, and an adjustable horizontal surface 4 of a predetermined length is formed on the lower surface of the stair paving stone main body 1 in parallel with the horizontal tread surface 2 from the front. A downwardly inclined inclined wall 5 is formed behind the adjustment horizontal surface 4, and a bottom inclined surface 6 connected to the upwardly inclined mortar is formed in connection with the inclined wall 5. Further, a rear inclined surface 7 substantially parallel to the inclined wall 5 is formed at the rear of the horizontal tread surface 2 and at the end of the bottom inclined surface 6. Reference numeral 9 denotes leveling mortar applied to the upper surface of the foundation concrete 10.

(Function) This invention has the above-mentioned configuration, and when the stair paving stone body 1 is to be laid now, the foundation concrete 10 is poured in advance in the form of an inclined surface at the location where the outdoor stairs are to be constructed. Next, leveling mortar 9 is laid on the upper surface of this foundation concrete 10, and the bottom inclined surface 6 of the stair paving stone body 1 is placed and fixed on top of it, and the rear of the horizontal tread 2 of the next paving stone body 1 is adjusted to the horizontal plane. Insert it below 4. If the width of the horizontal tread 2 is to be increased at this time, the horizontal tread 2 is inserted into the adjustment horizontal surface 4 shallowly and sequentially. On the other hand, if the width dimension is to be reduced, the horizontal treads 2 are successively inserted deeper into the adjustment horizontal surface 4 and the construction is completed.

(Effects of the invention) As described above, this invention has the effect that outdoor stairs can be constructed extremely quickly, easily and reliably, and that the width of the vertical plane of the horizontal tread of the stairs can be adjusted back and forth using one type of paving stone body. Dimensions and angles can be easily adjusted and changed at will by moving the
There is an excellent effect that has never been seen before in that stairs can be constructed by appropriately alternating the width dimensions of the treads. Furthermore, because of the sloped bottom surface provided on the lower surface of the stair paving stone body, there is no need to excavate the ground where the stairs are to be constructed into a stair-like shape; all that is required is to slope the ground and lay leveling mortar. There is a convenient effect that the stairs can be easily laid by sequentially connecting the stair paving stone bodies.

In addition, the adjustment horizontal plane formed horizontally in front of the bottom slope of the paving stone body has the effect of being stably placed on the tread at the rear of the paving stone bodies that are successively connected, and the length of the adjustment horizontal plane. The width dimension of the tread can be freely adjusted, allowing for mass production, and the size of the paving stone body can also be freely adjusted and molded, resulting in a very economical effect. Furthermore, by installing natural stones of various colors and patterns on the horizontal treads and the vertical surface of the front part, outdoor stairs can be made very beautiful, and the drainage slope can be easily adjusted. It also has the effect of fully fulfilling the role of anti-slip.
