DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. The Prior Art
Ground covering elements serving as paving blocks and having a rectangular base surface and planar side surfaces extending transversely to the rectangular base surface are known (DE-OS 2,448,312). During laying of these ground covering elements or when arranging the same in the laying packet, the ground covering elements are arranged with the side surfaces in contact with each other, resulting in a substantially closed surface which has the disadvantage of making the run-off of liquids into the ground, for example, rainwater, difficult. In addition, the non-connected ground covering elements are not suited for a mechanical laying since during the absence of sufficiently large friction forces between adjacent ground covering elements, individual ground covering elements often fall out of the laying packet.
SUMMARY OF THE INVENTION
It is an object of the present invention to improve a paving block of the above type in such a manner that after laying the same with additional paving blocks, the run-off of liquids is possible and a safe mechanical laying is provided.
According to the invention, this object is achieved in that the outer side surfaces of the body of the stone each have two strip-like attachments with a spacing "b" from each other, forming grooves with a spacing "a" between the center planes of the grooves and the nearer corner edges, and an attachment with a spacing "a" relative to the remote corner edge, whereby spacing "a" of the last-mentioned attachments corresponds with the distance of the center planes of the grooves from the first-mentioned corner edges. The faces of the body of the stone each have two attachments forming a groove with spacing "b" from each other, whereby the attachments of the faces are arranged with spacing "a" from the nearer corner edges. Furthermore the inner side surfaces of the body of the stone each have an attachment with spacing "a" from corner edges. Within the laid composite, the attachments form spacing joints relative to adjacent identical stone bodies and hook-ups with attachments of adjacent stone bodies.
Due to its geometric shape, the paving stone of the invention so created can be laid in a simple way with variations of the laying pattern and is suitable for forming laying sets which can be handled (by machines). In this connection, the paving stone jointly with other paving stones forms joints via which rainwater or the like can be drained off free from obstruction. Furthermore, by supporting the strip-like attachments on adjacent stone bodies, adequate friction grip is obtained as protection against displacement or shifting of stone bodies. For example, this grip occurs when the paving stones are subjected to vehicular traffic, whereby the "hook-ups" support safe cohesion in the course of the laying operation and in the installed or laid condition.
Additionally, while maintaining the groove-forming extensions and a single extension on the two outer longitudinal surfaces of the stone body, the inner longitudinal surfaces of the stone body are provided with one extension each as a tongue for associated grooves of adjacent stone bodies, and selectively to arrange on the end surfaces of the stone body either two extensions for forming grooves or only one extension for forming a tongue. The modifications in the paving block regarding the arrangement of grooves and tongues, which may be selected arbitrarily, make different paving patterns and an adaptation of the pavings to local conditions possible. It is also conceivable to provide the outer longitudinal surfaces of the stone body with groove-forming extensions and one single extension each, while the inner longitudinal surfaces have two extensions forming a groove or one extension serving as a tongue, and the end surfaces each have one extension or have extensions forming a groove. In an additional modification of the stone body, it is provided selectively to equip the outer longitudinal surfaces of the stone body with two extensions forming a groove and a
