Paver and pavement made therefrom

Abstract

The invention relates to a paving stone (1) and to a paving produced using same. A strip-shaped connection section (4) is provided at least on one lateral face of the paving stone, which vertically projects from same and interacts with strip-shaped connection sections of adjoining stones in the course of producing a paving and establishing a connection. The connection section (4) has a stepped shape with at least three graduated shoulders one over another. This both achieves a joint that expands in the upward direction, and prevents the pointing from loosening or being cast upward when forces act upon the paving, for example when subject to vibrations.

Claims

1. A paver having a bottom face, a top face and a plurality of side faces from at least one of which outwardly projects at least one vertical connector ridge that in laying of pavement fits with connector ridges of neighboring pavers, the at least one connector ridge each having a stepped shape with at least three ridge sections separated by step-like shoulders and in a row, the connector ridge sections separated from one another by the shoulders projecting horizontally from the respective side surfaces less and less from the bottom face to the top face.

2. The paver according to claim 1, wherein the shoulders extend completely around each of the respective at least one connector ridge.

3. The paver according to claim 1, wherein all of shoulders are of the same width.

4. The paver according to claim 1, wherein the shoulders extend downward and are angled outward at more than 30° from the respective side face of the respective paver.

5. The paver according to claim 4, wherein an upper face of each of the at least one connector ridge extends similarly downward and is angled outward at an angle of more than 30° from the respective side face of the respective paver.

6. The paver according to claim 1, wherein each of the at least one connector ridge only extends over part of a height of the respective paver.

7. The paver according to claim 1, wherein each of the at least one connector ridge is generally semicircular in horizontal section or is formed as a trapezoid with a part-circular lateral outer side.

8. The paver according to claim 1, wherein the lowermost connector ridge section is formed with side parts that merge into the respective side face of the paver with side parts of an adjacent paver.

9. The paver according to claim 1, wherein there is on each side face a pair of the at least one connector ridges.

10. The paver according to claim 1, wherein each of the at last one connector ridge has a vertical, elongated depression in its outermost edge.

11. The paver according to claim 1, wherein the at least one connector ridge is arranged in groups of three.

12. The paver according to claim 1, wherein the at least one connector ridge is arranged in groups of two separated by a space.

13. Pavement formed by a plurality of the pavers of claim 1.

14. The paver according to claim 1, wherein each ridge section is of constant cross-sectional shape and size from its upper end to its lower end.

Description

(1) The invention is explained below with reference to embodiments shown in the drawing. Therein:

(2) FIG. 1 an isometric view of four pavers placed next to one another;

(3) FIG. 2 is a large-scale view of a section of a paver of FIG. 1; and

(4) FIG. 3 is an enlarged view of part of a connector ridge.

(5) FIG. 1 shows four pavers 1, each of which is rectangular in horizontal section. The pavers 1 each have a bottom face, a top face 2 and four side faces 3. Each side face is provided with two pairs of connector ridges 4. Each connector ridge is in the form as a vertical bar projecting outwardly from the respective side face 3 from the bottom face of the respective paver 1 extends upward to just below the top face 2. In horizontal section each connector ridge 4 has approximately the shape of a trapezoid with a semicircular lateral outer side.

(6) The pairs of connector ridges 4 are so spaced from one another that they fit with the pairs of connector ridges of adjacent pavers to form a pavement bond. When the pavers are fitted together, the connector ridges of adjacent pavers fit to form a joint gap extending from the bottom face to the top face and of increasing with going upward.

(7) The exact shape of a connector ridge 4 is shown in FIG. 2. The connector ridge 4 shown here is stepped and has from bottom to top three distinct connector ridge sections 5, 7 and 8 delimited by shoulders 11 and 10. Each connector ridge has an upper end face 9. Planes of the shoulders 11, 10 and the upper faces 9 extend downward from and are angled outward at more than 30° from the respective side faces of the respective pavers.

(8) Due to the stepped formation of each connector ridge 4, its three stacked connector sections 5, 7 and 8 extend vertically. Each connector ridge section 5, 7 and 8 therefore projects less and less than the immediately underlying section from the bottom upward on the respective side faces, so that a corresponding joint-gap flare results. A uniform upwardly tapering shape of the connector ridge is therefore avoided. This has the advantage that forces act perpendicular to the surface of the connector ridge, for example when the pavement is vibrated, in the horizontal direction and have no diagonally upward vector effective on the joint filling between adjacent connector ridges and thus there is essentially no loosening of the inserted joint material or ejection of same upward. Compression of the joint material is therefore essentially not reduced.

(9) In the embodiment of a connector ridge 4 as shown in FIG. 2, the lowest and most projecting connector ridge section 5 is formed so that its side parts 6 extend laterally and merge with those of the adjacent paver. In this way, the joint material is prevented from getting stuck.

(10) In the embodiment of a connector ridge 15 as better shown in FIG. 3 its outermost edge or apex is formed with a recess or groove 14 extending longitudinally of the connector ridge to prevent lateral displacement of joint material between the outermost edge of the connector ridge 15 and the side face of the adjacent paver, for example from vibration, so that the corresponding buffer effect is not lost. The recess or groove 14 holds joint material at this point and also ensures a corresponding buffer effect here.

(11) Instead of a depression or groove 14, a corresponding flattening in the outermost edge of the connector ridge can be provided at this point to inhibit lateral displacement of joint material. Such a flattening is shown in FIG. 2.
