Abstract

In a flat square slab with a smooth surface and tongue-like attachments perpendicular to the side surfaces, in order to provide a large number of layout combinations, each side surface (26, 27) has two projections (22, 22', 22''), wherein each projection (22) is formed on a corner edge (23) of two adjacent side surfaces (26) and one projection (22') is formed on the same side surfaces (26) at the other corner edge (24) and the projections (22'') are arranged at a slightly greater distance from the edge corners (24, 25) on the other two side surfaces (27) than the length of the attachments (22, 22') looked at from the smooth surface of the slab.

Description

The present invention relates to a square plate-shaped paving stone having a flat upper side surface and a flat edge-shaped protrusion extending perpendicularly to the side surface.
It is already known to arrange a flat edge projection on the side of the plate-shaped paving stone that acts as a spacer and allows the formation of a joint that can be filled with humus or mineral materials (European Patent No. A0274344, (See German Utility Model No. 8717484). In the case of known paving stones, it can be laid only with a few types of combination methods.
An object of the present invention is to make a paving stone that can be laid in many kinds of combination systems while maintaining a symmetrical linear joint.
According to the present invention, the object is that each side has two projections, one projection is integrally formed on the corner edge between two adjacent sides, and the other projection is on the other side on the other side. It is integrally formed on the corner edge, and two protrusions are arranged on the other two side surfaces at a distance slightly larger than the length of the protrusion when the flat upper surface of the pavement is viewed in plan. Is achieved.
According to the formation of the paving stones according to the present invention, the paving stones can be laid in contact with and supported by the projections, and can be laid in large or small intervals with each other in a cruciform shape or a longitudinal pile shape. The advantage is that it can be laid by the method.
Furthermore, in the paving stone according to the present invention, the protrusion is formed at the same height as the paving stone thickness. It is also proposed that the protrusion is formed at a height smaller than the paving stone thickness and ends at the lower side of the upper side. As a result, a condition for making the appearance so that there is no gap is obtained. Furthermore, the projections are bounded by a flat inclined surface or a curved surface, which extends obliquely toward the protruding end and a flat inclined surface or curved surface whose upper end extends in the direction of the upper surface of the paving stone, for easy and reliable molding in concrete tools. ing.
Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 4 is a plan view of a laying pattern in which the paving stones in FIG. 1 are laid in a longitudinal stack with a wide gap;
FIG. 5 is a plan view of a laying pattern in which the paving stones in FIG. 1 are laid in a longitudinal stack with a narrow gap,
FIG. 6 is a plan view of a laying pattern in which the paving stones in the first are laid in a cruciform shape with a narrow gap and a wide gap,
FIG. 7 is a plan view of a laying pattern in which the paving stones in FIG. 1 are laid in a longitudinal stack with a narrow gap and a wide gap,

In the case of the paving stone 30 in FIGS. 1 to 9, each of the four side surfaces 26, 27 has two protrusions 22, 22 ', 22 ″. One protrusion 22 is adjacent to the two side surfaces. The other one projection 22 'is integrally formed on the other side edge 24 on the same side surface, and two projections on the other two side surfaces 27. 22 ″ is arranged at a distance slightly larger than the length of the protrusions 22, 22 ′ from the corner edges 24, 25 when the flat upper surface of the pavement is viewed in plan. These protrusions 22, 22 ′, 22 ″ can be formed at any height, for example having a height corresponding to the pavement thickness or smaller than the pavement thickness. In order to achieve this, the projections 22, 22 ', 22 "are bounded by side surfaces 28 that extend at an angle towards the protruding end. In order to obtain a visually joined joint, the projections 22, 22 ', 22 "are bounded by a flat inclined surface whose upper end extends in the direction of the upper side of the paving stone or by a curved surface 29 (see Fig. 9) In the figure, reference numeral 31 denotes a virtual separation line for obtaining the paving stone half 32 (see FIG. 8).
