Shaped stone, in particular turf or embankment stone

The invention relates to a shaped stone, in particular turf or embankment shaped stone or the like, which consists of ribs or webs abutting one another at right angles to form cavities for the reception of lawns, the surfaces of the ribs or webs being provided with incisions in bsstisstsn sections and in which the Ends of the ribs or webs protrude over the peripheral ribs as cams. The surface of such a shaped stone lies in the plane of a lawn and breaks through the lawn in punctiform distribution, so that, for example, a vehicle can drive on these punctiform surfaces without damaging the lawn If such a shaped stone is used as an embankment stone, for example to secure the higher edges of a river bed or the embankment on an Auvcbahn or the like, there is no load from vehicles ate the fortified river bed leads to high water or rainwater flows down an embankment. In order to give the shaped stone a secure position when used as an embankment stone, it has relatively large dimensions, for example 60 × 60 cm. This makes its own weight very large. However, the risk of swimming away is reduced. Such

aor nrx j.nuuiig ion ob, buidu rOTüks * Sj.Ti anzugSbSU, which can be kept small and can therefore be easily laid without the risk of port flooding when used as an embankment stone.

This object is achieved according to the invention in that each shaped block has at least two protruding cams on at least two opposite sides, which are spaced apart from one another in such a way that they enclose the end cams of two further blocks placed next to one another. Such stones can be laid in Virbund, no that the lined Pormsteine form a solid-contained unit.

It has proven to be useful to set the clear distance between two adjacent cams to be equal to twice the width of a cam plus double the distance from the edge of the stone. If you give the webs the same width as the cams and If the spacing of the webs is the same as the cam spacing, then the webs can also be used to fit into the composite. the The ends of the webs then take on the role of the cams.

In a further embodiment of the invention, d; .r molded stone two webs lying parallel to one another, which have a uniform height over their entire length.

The building authorities require Hitunter to use larger stones. Such a stone can have at least three continuous ones Have webs, the ends of which can serve as cams, and crouches are advantageously provided on the outer webs, possibly at different distances, from which at least two have a distance from each other such that they the

Include end cams of adjacent blocks. The distance the webs are advantageously chosen so that they also enclose the end cams of adjacent stones.

With given dimensions, the cam spacing is from each other be different over the length of the web. There is also sometimes no need for the end cam to be spaced from the end of the stone have to. Because of the different distances, the cams are symmetrical in a further embodiment of the invention arranged to the center line of the stone so that the stone can also be laid centrally symmetrically.

As is known per se, transverse webs of different heights are provided between the webs. Sections of the crossbars have the same height as the webs lying parallel to one another.

When used as an embankment, the cross webs need to show no surveys. They can be kept lower over their entire length than those lying parallel to one another Bridges. Such a stone takes up more lawn area.

For manufacturing reasons, the webs will be designed to be concavely rounded.

In a further embodiment of the invention, the cams drop towards the edge of the stone in order to also accommodate the lawn here to be able to.

The molded block according to the invention not only has the advantage that it can be laid in a composite, but it can also be lighter manufacture than the stones belonging to the state of the art.

In the formst one belonging to the prior art, the profile is pressed into the cement mass from above. This is cumbersome and time consuming.

In the molded stone according to the invention, the profile can be in the base be at least partially incorporated into the form, so that only the cement mass is filled in during manufacture needs to become. The finished shaped stone is turned around for brewing.

Since it is still important in the production of shaped stones, the base under the shaped stones and the pulling out the actual mold while the cement mass is still fresh in order to place the molded bricks on a transport board, according to the invention, the base can be designed in the shape of a wavy line, the troughs then being produced during manufacture Stone embody the continuous webs * In the direction of the webs, the base is pulled out from under the form. the As before, transverse ribs are usually obtained by placing a mold on the base.

As is known, transverse grooves of different heights can be provided between the webs of the same height lying parallel to one another be. The different heights are in turn obtained by the wave formation of the base. The bridges themselves will be formed by the mold during molding.

Exemplary embodiments of the invention are shown in the drawing, namely show:

1 shows a shaped block in a perspective illustration; FIG. 2 shows the molded block of FIG. 1 in a plan view in a composite; Fig. 3 shows the reforests a of Figure 1 in a modified composite.

Pig. 4 the shaped stone of the Pig. 1 in a changed group;

Pig. 5a the top view of a molded block of larger dimensions;

Pig. 5b shows the front view of the Pig's Pormstein. 5a;

Pig. 6 shows a modified shaped block in a perspective illustration.

According to Fig. 1, the shaped block has two parallel to each other Bars 1 and 2, the surface of which is the same height and continuous. The webs 1 and 2 are through cross webs 3> and 5 connected to each other. They have elevations 6, 7 and, which in the plane of the surfaces of the webs 1 and 2 lie.

At a distance a from the end of the shaped block are cams 9 »10, 11 and 12 are provided, which slope towards the edge of the Pormsteines to fields in the juxtaposed state of the Pormstein free for inclusion of lawn.

The distance b between the Noeksn is dimensioned such that the cams 9 and 12 according to FIG. 3 enclose the end cams 20 and 21 of two stones 30 and 31 placed one against the other. the The composite stones are thus immovably connected.

The width of the cams 9, 10, 11 and 12 is c. We have b = 2 (a + c).

According to Pig. 2, the ends 9 ¹ , 12 ^{1 of} the webs 1 and 2 serve as cams which enclose the ends 20 'and 21' of the stones 23 and 24, which also serve as cams.

Fig. 4 shows that the composite is obtained even when the shaped bricks can be arranged in any order. The stones 40 »41 and 4? are arranged crosswise to each other.

Figs. 5a and 5b show a molded block of larger dimensions, for example 40 χ 60 cm. Such large stones sometimes become building inspections required for certain purposes. Three webs 50, 51, 52 of the same height are provided here, which ones are connected to one another by a plurality of transverse webs 53, 54. The distance between the webs 50, 51 and 51, 52 from one another is in each case b. The webs 50 and 52 carry cams 55, 56, 57, 58, 59, 60, 61, 62. The width of the cams is c = ■ *. The cams 55 and 58 sit so that they are of two webs 5ö, 31 or 51, 52 can be included, directly at the end of the webs 50, 52. In addition, the cams 56, 57 and 60, 61 the distance b from each other, so that two end cams of adjacent stones can be fitted between these cams. The cams are also arranged symmetrically to the line M-M, so that the stone is also in a centrally symmetrical position can be relocated.

Fig. 6 shows a shaped block according to FIG. 1, in which, however, the webs 3 * 4, 5 with their elevations 6, 7, 8 through Bridges 63, 64, 65 are replaced, which are concavely rounded and no longer show any elevation in order to accommodate more lawn area can.
