Abstract
Known groundcovering elements (44) consist of three basic shaped slabs which are connected to form a unit and which are delimited from one another by at least two dummy joints (stem dummy joint 74 and middle dummy joint 81), the peripheral surface having projections (67, 68, 79) and depressions (69, 70, 80) along an (imaginary) base line to form a toothing. To improve the stability and laying of such groundcovering elements (44), it is proposed to make these T-shaped by means of a half-size stem (13) formed approximately centrally on an elongate crossbar (12). When rhombi (45-47) are used as the basic shaped slab, the groundcovering element (44) has the form of an inclined "T".
Claims10
A concrete groundcovering element (10, 44), comprising:
- at least three basic identically shaped slabs which are connected to one another to form a T-shaped unit composed of:
- a longitudinal crossbar (12) formed by two equiaxially arranged ones of said three basic shaped slabs;
- and
- a stem (13) arranged approximately centrally transversely relative to said crossbar (12), and including a third one of said three basic shaped slabs;
- and
- at least two dummy joints which delimit said three basic shaped slabs from one another, and comprising:
- a longitudinal dummy stem joint (17, 74) which extends between the step (13) and crossbar (12) and connects longitudinal side portions (18, 19) of the crossbar (12) to one another;
- and
- a middle dummy joint (14, 81), passing approximately centrally through the crossbar (12), and extending transversely to the longitudinal direction of the crossbar (12);
- and wherein:
- said T-shaped unit has eight corners (26-33);
- each of said basic shaped slabs has peripheral faces composed of slab edge portions (35, 36) which are of only two different lengths and which define projections (37, 67, 68, 79) and depressions (38, 69 79, 80) forming a toothing;
- short ones (35) of said edge portions adjoin said corners (26-33), have approximately half the length of longer ones (36) of said edge portions located between the short ones, and include a right angle between them;
- and
- each of said longer edge portions (36) forms the same obtuse angle with adjoining short edge portions (35) and with adjoining longer edge portions (36).
