Description

Coping stone

The invention relates to a coping stone with a block-shaped overall shape, with a recess arranged in a top side, which 5 slopes at an angle relative to said top side and the depth of which increases towards one side.

A coping stone of this kind has proven effective in principle, especially for reinforcing the top surface of 10 dyke constructions, because the recess - or the areas of the top side surrounding it - function as breakwaters on the one hand, and, on the other hand, make any unevenness resulting from subsidences less easy to perceive. One disadvantage, however, is that water can collect in the recess, which is 15 frequently polluted, so that there is a risk of dirt accumulation or of the recesses becoming clogged.

The invention has set itself the objective of overcoming the above-mentioned disadvantage.

20

For this purpose, it is proposed in a coping stone of the generic kind that in its deepest area, the recess should directly adjoin the side face of the coping stone.

25 This makes it possible for water to run off through the joints of adjacent coping stones.

It is advantageous for a groove to be formed in each of two adjacent sides and for a tongue to be formed on each of two 30 other adjacent sides in order to allow the stones to be laid in the "tongue and groove" system.

2

It is preferably proposed that the recess is designed in a wedge shape. In particular, the recess can have a flat base area, the angle of inclination of which relative to the underside may be 5° to 20°, especially 8° to 12°.

5

It may be contemplated that there is a direct transition from the recess into the top side, on the one hand, and also a direct transition into the side face, on the other.

10 It is conveniently proposed that the recess has a rectangular base area.

In its deepest area, the recess may have a depth of between 10 % and 50 %, especially between 20 % and 30 %, of a height 15 of the coping stone.

The recess is preferably delimited by three U-shaped edge regions of the top side, which have a width of between 10 % and 30 %, especially 15 % - 25 %, of a width or length of 20 the coping stone.

It may be envisaged that the top side and underside are square .

25 In cross-section, the groove and tongue may be semicircular.

The invention also relates to a laying arrangement comprising a number of coping stones in accordance with the invention, wherein the coping stones are arranged in 30 parallel, adjacent rows, which are alternately staggered relative to one another by half a stone's width, and the recesses in all the stones point in the same direction.

3

It may be contemplated that the laying arrangement slopes at an angle, the recesses each sloping downwards towards their deepest regions.

5 Further advantages and features of the invention will become clear from the following description of a preferred embodiment, reference being made to a drawing in which

Fig. 1 shows a schematic view of a coping stone in 10 accordance with the invention, seen from above,

Fig. 2 shows a side view in direction II in Fig. 1,

Fig. 3 shows a front view in direction III in Fig. 1, 15

Fig. 4 shows a section view along line IV - IV in Fig. 1, and

Fig. 5 shows a perspective view of a laying arrangement of 20 coping stones in accordance with the invention.

Figs. 1 to 4 illustrate an embodiment of a coping stone in accordance with the invention, which is block-shaped over all and has four sides 2, 4, 6, 8, arranged alternately 25 perpendicularly to one another, an underside 10 and a top side 12. Worked into each of two adjacent sides 2, 4 is a groove 14 which is semicircular in cross-section, while the two opposing adjacent sides 6, 8 have a tongue 16 projecting outwards which is semicircular in cross-section. This makes 30 it possible to join together stones laid adjacently in a positive fit.

4

Sunk into the top side 12 is a sloping recess 18, the depth of which increases constantly towards one side, in this case the side 8. The recess has a substantially rectangular base area 20 and is formed in a wedge shape in the embodiment 5 illustrated, the base area 20 being planar and having an angle of inclination relative to the top side 12 or underside 10 of about 10°.

The recess 18 is delimited by three U-shaped edge regions 10 12a, b, c of the top side 12, which have a width of between 25 % and 30 % of a width or length of the coping stone. In the embodiment illustrated, the coping stone and its top side and underside 10, 12 are sguare.

15 The depth t of the recess 18 is about 25 % of a height h of the coping stone.

According to the invention, the recess 18 is arranged in the top side 12 of the coping stone in such a way that at one 20 end, it passes over directly into the top side 12, in region 12b of the latter, and at its opposite end, which corresponds to its deepest region, it passes over directly into one side 8 or adjoins it directly, so that no water can collect in the recess, irrespective of its inclination when 25 laid.

This advantage can also be seen from Fig. 5, in which a laying arrangement of a number of coping stones in accordance with the invention is illustrated. The coping 30 stones are arranged in parallel, adjacent rows 24, 26, where one row 24 is arranged so as to be staggered relative to an adjacent row 26 by half a stone's width.

5

The deepest regions of the recesses 18 end in the region of a joint with the adjacent row, so that, depending on the overall inclination of the laying arrangement, water which enters the recesses 18 can flow away either through the 5 joints between adjacent rows of stones or in the opposite direction directly out of the recess 18 over a respective area of the top side 12b.
