Description

The present invention relates to a stone element having the features of the preamble of claim 1.

Such stone elements are known. Hereby, the paving or laying work can be simplified because no individual stones must be laid, but stone elements, each corresponding to a certain number of individual stones, which caused by dummy joints separate stone heads give the impression of an existing individual stones gutter or a corresponding paving strip ,

For example, such stone elements are known which have three stone heads and in which the middle stone head is offset relative to the two curb heads. By this staggered arrangement, a better connection of the created gutter or of the created paving strip is achieved compared to a linear arrangement of the three stone heads.

Depending on the intended use for creating a gutter or a paving strip, the tops of the stone elements are formed accordingly. In a gutter, the top of the curb heads is preferably beveled inwardly, while the tops of the stone heads form a flat surface to create a paving strip.

Curved gutters or plaster strips can only be produced to a limited extent with the known stone elements, since joints which open outwards result in joints which on the one hand cause an unsightly appearance and on the other hand cause the joint material to fall out, which is undesirable. This deficiency is counteracted by separate curved stones.

It is also known to provide such stone elements with spacers that cooperate with corresponding spacers or composite sections of adjacent stone elements to define the width of the joints or to achieve a composite effect between the stone elements.

From the DE 296 14 953 U1 a paving stone is known having the features of the preamble of claim 1. Here, the middle stone head is facing the two curb heads. In the provided spacers are punctiform spacers, which are arranged approximately in the middle of the respective side surface.

The DE 102 05 135 A1 describes a paving stone with a plurality of staggered stone sections, wherein the paving stones described and illustrated each have two stone heads or four stone heads. On the corresponding side surfaces a plurality of strip-shaped spacers is arranged.

From the DE 201 03 301 U1 For example, a pavement gutter is known that, in one embodiment, has three stone heads, the middle stone head of which projects from the two curb heads. All stone heads are the same length. Strip-shaped spacers are provided approximately in the middle of the corresponding side surfaces.

The present invention has for its object to provide a stone element for creating multi-line gutters or plaster strip of the type mentioned, with which such grooves or strips can be created very easily and variably.

This object is achieved with a stone element of the type indicated by the characterizing features of claim 1.

In the solution according to the invention, the stone heads in the axial direction of the gutter to be created are staggered offset from one another and formed differently long, the length increases from one curb to the other curb increases, in particular continuously. Due to the different lengths the stone heads is achieved that when curved in the same direction automatically a curved groove or a curved plaster strip is formed, either in one direction or in the other direction. The corresponding differences in length determine the respective radius of curvature. On the other hand, can be created by the inventively designed stone elements in opposite directions, ie a long stone head is alternately combined with a short stone head, a straight groove or a straight pavement strip created.

An uninterrupted sequence of elements in the same direction leads to a narrow arc. If the alignment in the same direction is interrupted by elements that are laid in the opposite direction, further bends result accordingly.

The differences in length are dimensioned in the stone element according to the invention so as to give the above reproduced possibilities. The differences in length are therefore relatively small.

Another feature of the invention is that corresponding strip-shaped spacers are provided, which cause the following: When placing the stone elements, the spacers of adjacent stone elements come to rest. As a result, on the one hand, a composite effect of the stone elements is achieved with each other perpendicular to the channel axis, on the other hand, a lateral closure of the joints, so that dry filled grout can not escape sideways. This effect is given in an arcuate or curved laying and a straight-line installation.

According to the invention is therefore achieved by the differently long stone heads, that the above-described three types of laying are made possible with a single shape of a stone element. Furthermore, in all three types of laying a composite effect perpendicular to the joint axis and a lateral joint closure is achieved.

The stone element according to the invention thus has three stone heads, which are formed stepwise longer in the axial direction of a Randsteinkopf on the middle stone head to the other edge stone head, wherein the spacers are provided on the side surfaces of the two curb heads. This makes it possible to create curved and straight gutters or plaster strips in a particularly simple and practical way.

In accordance with the invention, the stone heads stand on the one side at the same distance opposite the neighboring stone head. Since the stone heads have different lengths, they stand here on the opposite side to different lengths before. Since the differences in length are relatively small, the Aneinanderetzen the stone elements is not hindered thereby.

As far as the spacers or composite sections are concerned, they are arranged offset on opposite side surfaces. When putting together stone elements thus occurs in each case a further inner spacer of a stone element with a further outer spacer of the adjacent stone element approximately in contact. In this case, the spacer of a curb on the inside and the spacer of the other curb outside is preferably located on the outside of a stone element on the same side. Even with slight Keilfugen is thus still a closure of the joints given.

The spacers are preferably formed approximately triangular or semicircular in horizontal section. When adjoined stone elements they lie with their flanks approximately to each other. By varying this system (displacement along the flank surface in sheet laying) different radii of curvature of the gutters or plaster strips can be adjusted, with a shift is possible so far that the lateral closure is still maintained.

In a further development of the stone element according to the invention, the edges or outer surfaces of the transition regions between the stone heads are curved. The vertical side surface of a stone head therefore passes over a curved transition surface into the vertical projecting side surface of the adjacent stone head. At these curved vertical transition surfaces vertical edges of adjacent stone elements can be supported, these curved Transition surfaces can also serve to fix the position of the stone elements in conjunction with the provided on the curbs spacers. As a result, the connection between the stone heads is reinforced in the base area of the elements and the risk of breakage at the transition between the stone heads is reduced.

Furthermore, further spacers may be provided in the stone element formed according to the invention on the projecting axially parallel side surfaces of the stone heads. These additional spacers can additionally secure the joint dimension between the projecting axially parallel side surfaces of adjacent stone elements. Here, too, a spacer of a stone element preferably cooperates with a spacer of the adjacent stone element arranged offset therefrom.

As mentioned, a curved groove or a curved plaster strip is formed when a plurality of stone elements are placed in the same direction, so that in each case the long curbs are arranged in the same edge region. Due to the curvature, an outer corner of the juxtaposed stone elements then projects outwards in each case. In order to prevent this, in a particular embodiment of the invention, the axially parallel outer side surfaces of the curb heads are slightly bevelled or curved in the axis-parallel direction with respect to the groove axis parallel, so that the above-described effect no longer occurs or is mitigated. It then results in a more uniform transition between adjacent stone elements, which comes close to a true curvature.

If a gutter is to be formed with the stone elements according to the invention, such stone elements are preferably used in which the top side of the curb heads is chamfered inwards or drops like a desk. The middle stone head or the middle stone heads can in this case have a horizontally extending surface in order to produce a corresponding gutter effect in this way. If the stone elements used for the creation of paving stone strips, the tops of all stone heads are preferably formed horizontally (at right angles to the side surfaces).

The stone elements designed according to the invention are preferably designed as artificial stones made of concrete.

The invention further relates to a gutter or a strip which is characterized in that it is composed of a plurality of stone elements of the type described above. Such a groove or such a strip is formed by fitting together stone elements according to the invention, wherein the Fugenmaß is secured by the provided spacers or composite sections. A lateral escape of the filled into the joints dry grout material is prevented by the spacers on the curbs, which extend strip-shaped almost over the entire height of the stone elements.

By equidistant juxtaposition of stone elements describes such a groove or such a strip a Right or left arc, and by alternately opposing juxtaposition of adjacent stone elements (alternately short and long stone head) a rectilinear gutter or a corresponding strip.

In the case of the stone element formed according to the invention, in a particularly preferred solution, the shorter length from stone head to stone head is dimensioned so that the stone heads protrude on both sides by the same distance from the neighboring stone heads. In other words, the stone heads jump on one side by an equal amount and jump on the other side by an equal amount, the amounts between the two sides can be different sizes. This ensures that an application of the stone elements both in the same direction and in opposite directions (alternately rotated by 180 °) can be realized in a straightforward way.

The invention will be explained in more detail below with reference to exemplary embodiments in conjunction with the drawing. Show it:

a top view like FIG. 1 with a smaller installation radius and a larger outer joint;

FIG. 3

a top view of two juxtaposed Stone elements of another embodiment, in which case the stone elements are placed against each other in opposite directions; and

FIG. 4

various strips composed of the stone elements with rectilinear and curved embodiments.

This in FIG. 1 shown in plan view stone element 1 has a common base (not shown) and three from the base upwardly extending stone heads 2, 3 and 4 in a rectangular shape, which are separated from each other by dummy joints 13. When viewed from above, therefore, the impression arises that there are three individual stones.

The three stone heads 2, 3 and 4 are arranged staggered offset from each other, each with a stone head opposite the neighboring stone head protrudes or springs back. An essential feature is that the stone heads have a different length in the axial direction of a channel to be laid or a strip to be laid, ie parallel to the direction of the dummy joints. The stone head 2 is formed here the longest, the middle stone head 3 has a mean length, and the in FIG. 1 lower stone head 4 is formed shortest. The differences in length are so great that the stone heads protrude on one side by the same amount with respect to the neighboring stone head. In other words, in FIG. 1 to the right, the stone head 3 faces the stone head 1 by the same distance as the stone head 4 with respect to the stone head 3. This is the case on the left, as well Here, however, the measure by which the stones protrude differs from that on the right side.

The transitions or bridges between the individual stone heads on the base are rounded, as shown at 9.

Furthermore, the stone head in the end regions of the perpendicular to the axis extending side surfaces of the curb heads 2 and 4 each have a strip-shaped spacer 5, 6 and 10, 11, wherein the spacers are arranged on opposite side surfaces so that they laid the spacers of adjacent stone elements Contact state and form a seal for joint material with them in the lateral direction. FIG. 1 shows how the spacers 5 and 11 are arranged offset to the spacers 6 and 10, so that in the juxtaposed state of the desired lateral closure is achieved, as in FIG. 1 shown.

Furthermore, the stone element on the projecting side surfaces depending on a further spacer 7, 8, which ensure a corresponding joint spacing, namely for the axial direction of joints.

When the stone elements in the in FIG. 1 illustrated manner, results due to the different lengths of the stone heads automatically a curved installation with a radius of for example 4.0 m, as in FIG. 1 shown. In this state, the spacers 10, 11 fit snugly against each other and contact the neighboring stone head. In this way, a closure is formed, which prevents filled grout material can escape laterally from the joint.

According to FIG. 2 the stone elements are placed against each other so that a smaller laying radius (R = 3.4 m) with a larger outer joint of 12 mm results. In this case, contact the spacers 10, 11 in the outer areas only slightly, but still maintain the desired closure. There are therefore different installation radii possible without the desired closure is canceled.

Since the stone heads project on both sides by the same amount, they can be laid in the same direction as in FIGS. 1 and 2 shown, but also in opposite directions, as shown in Figure 3. Here, the longest stone head 2 (A) of a stone element with the shortest stone head 4 (C) of the adjacent stone element is placed against each other, so that overall results in a straight laid strip or a gutter. According to FIG. 3 the two stone elements shown are shown in a limit position in which the closure between the spacers 5, 6 is just maintained.

FIG. 4 shows a straight laid strip 20 and two curved strips 21, 22 with different Verlegeradien. It can thus be laid with stone elements identical shape a variety of stripes or gutters. As mentioned, while the top of all stone heads of a stone element can be flat be and form a right angle with the vertical side surfaces, so that strips can be laid. The tops of the curb heads can also be chamfered inwards, for example, so that gutters can be laid.
