Description

DESCRIPTION

Stone element for the realization of grooves and strips of cobblestones of several cells

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

Stone elements of this type are known. With them you can simplify the paving work or the laying work, since individual stones are no longer to be placed, but corresponding stone elements, each of them, with a specific number of individual stones, causing the stone heads separated from each other by means of false joints, the impression of a groove formed from individual stones or a corresponding cobblestone strip.

For example, stone elements of this type are known that have three stone heads, and in which the central stone head is disposed so as to be offset from the two stone heads of the edge. By means of this separate arrangement, in contrast to a linear arrangement of the three stone heads, a better connection of the groove made or of the cobbled strip made is achieved.

Depending on the purpose of use for the realization of a groove or a cobblestone strip, the upper parts 20 of the stone elements are correspondingly shaped. In the case of a groove, the upper part of the stone heads of the edge is preferably beveled inwardly, while for the realization of a cobblestone strip the upper parts of the stone heads form a flat surface.

25 With the known stone elements can be made grooves or strips of cobblestone curved only to a certain extent, since in this case, when placed next to each other joints are produced that open to the outside, which on the one hand cause an appearance ugly, and on the other hand they cause the material to cover up to come off together, which is somewhat unwanted. These shortcomings are offset by special segments.

In addition, it is known to provide this type of stone elements with corresponding spacers or joint sections, which act together with the corresponding spacers or joint sections of the adjacent stone elements, in order to set the width of the joints or Well get a bonding effect between the stone elements.

From document DE 296 14 953 U1, a paving stone is known which presents the features of the preamble of claim 1. In this case, the central stone head protrudes with respect to the two stone heads of the edges. In the case of the spacers provided, they are point-shaped spacers, which are arranged, for example, in the center of the corresponding lateral surface.

40 Document DE 102 05 135 A1 describes a cobblestone with several stone sections displaced between them, in which the cobbles described and depicted each have two stone heads or four stone heads. A large number of strip-shaped spacers is arranged on the corresponding side surfaces.

45 From document DE 201 03 301 U1 a grooving cobble is known which has in one embodiment three stone heads, of which the central stone head protrudes with respect to the two stone heads of the edges. All stone heads are shaped with the same length. The strip-shaped spacers are provided approximately in the center of the corresponding side surfaces.

The present invention is based on the objective of making a stone element for the realization of grooves or paving strips of several cells of the type mentioned at the beginning, with which this type of grooves or strips can be carried out in a special way Simple and variable.

This objective is achieved in accordance with the invention with a stone element of the type indicated by means of the characterizing features of claim 1.

In the solution according to the invention, the stone heads are arranged displaced between them in the form of a ladder in the horizontal projection in the direction of the axis of the groove to be made, and are shaped with different lengths, so that the length increases from one stone from the edge to the other

lose the edge, in particular increases continuously. By means of the different lengths of the stone heads it is achieved that, in the case that they line up next to each other in the same direction, a curved groove or a curved cobbled strip is produced automatically, and in particular Either in one direction or in the other direction. The corresponding length differences in this case set the corresponding radius of 5 curvature. On the other hand, by means of the stone elements formed according to the invention, in the case that they are lined up in the opposite direction, that is, a long stone head is alternately combined with a short stone head, a straight line groove can be made or a straight line cobblestone strip.

10 If the elements are lined up next to each other in the same direction uninterruptedly, a narrow arc is achieved. In the event that the placement in a row next to each other in the same direction is interrupted by means of elements that are placed in the opposite direction, then other arcs are produced correspondingly.

The differences in length are measured, in the stone element according to the invention, in such a way that the possibilities reproduced above occur. The differences in length, in this way, are relatively small.

Another feature according to the invention resides in the fact that corresponding strip-shaped spacers are provided that have the following effect: by placing the stone elements next to each other, the spacers of the adjacent stone elements are brought into contact . Thanks to this, on the one hand, an effect of union of the stone elements between them is achieved perpendicular to the axis of the groove, and on the other hand, a lateral closure of the joints, so that the material for covering joints Dry filling can no longer escape laterally. This effect occurs in the case of an arc or curved placement, and in the case of a straight placement.

25

According to the invention, it is thus achieved, by means of the stone heads of different lengths, that the three types of placement shown above be made possible with a single shape of a stone element. In addition, in the case of the three types of placement, a perpendicular joint effect is achieved on the joint axis, and a lateral joint closure.

30

With this, the stone element according to the invention has three stone heads that are shaped increasing length in the direction of the shaft as a ladder starting from the edge stone head, passing to the center stone head, to the other head of edge stone, the spacers being provided on the lateral surfaces of the two lateral stone heads. In this way they can be carried out in a particularly simple and practical way, grooves and curved cobblestones and straight lines.

According to the invention, the stone heads protrude on one of the sides the same path with respect to the adjacent stone head. Since the stone heads have different lengths, in this case they protrude on the opposite side in paths of different sizes. Since the longitudinal differences are relatively small, placement of the stone elements next to each other is not prevented.

As regards the spacers or the joining sections, they are arranged offset between them on opposite side surfaces. By placing the stone elements next to each other, with this, a spacer that is located more inwardly from a stone element with a spacer that is located more towards the outside of the stone element is brought into contact approximately. adjacent. In this case it is preferably arranged on the inside of a stone element on the same side of the spacer of one of the stones of the edge and on the outside of the spacer of the other stone of the edge. With this, even in the case of light cradle joints, the seals are closed.

The spacers are preferably formed in a horizontal section, for example in the form of a triangle or in the form of a semicircle. In the case of stone elements arranged next to each other, then they are in contact with their flanks. By varying this arrangement (displacement along the length of the flanks in the placement of the arches) different radii of curvature of the grooves or the paving strips can be adjusted, a displacement being possible provided that The lateral closure is still maintained. 55

In a variant of the invention of the stone element according to the invention, the edges or outer surfaces of the transition regions between the stone heads are curvedly shaped. The vertical lateral surface of a stone head, due to this, passes through a curved transition surface passing to the vertical projecting lateral surface of the adjacent stone head. On these surfaces of

Vertical curved transition can support the vertical edges of the adjacent stone elements, these curved transition surfaces can also serve as fixing the position of the stone elements together with the spacers provided in the edge stones. Thanks to this, the union between the stone heads is reinforced in the region of the elements and the danger of breakage in the transition between the stone heads is reduced.

Additionally, in the stone element according to the invention, other spacers can be provided on the lateral surfaces projecting parallel to the axis of the stone heads. These other spacers can further ensure the size of the joint between the protruding lateral surfaces parallel to the axis of the 10 adjacent stone elements. Also in this case, a spacer of one of the stone elements with a spacer of the set stone element arranged offset relative to it is preferably acting together.

As mentioned, a curved groove or a curved cobblestone strip is formed when several stone elements are placed next to each other in the same direction, so that the long edge stone heads are arranged in the Same region of the edge. As a result of the curvature, then, correspondingly, an outer corner of the stone elements placed next to each other towards the outside protrudes. To avoid this, in an embodiment of the special invention, the outer lateral surfaces parallel to the axis of the stone heads of the edge are slightly beveled or curved in the direction parallel to the axis with respect to the parallels of the axis of the groove, so that the effect explained above no longer occurs, or the less it softens. There is then a homogeneous transition between the adjacent stone elements, which resembles an authentic curvature.

When a groove has to be formed with the stone elements according to the invention, preferably the stone elements of the type in which the upper part of the stone heads of the edge are beveled inwardly or fall into mode are used. of lectern The central stone head or the central stone heads may in this case have a horizontally running surface, in order to generate a corresponding grooving effect. If the stone elements are used for the realization of cobblestone strips, then the upper parts of all the stone heads are preferably formed horizontally (at right angles to the lateral surfaces).

The stone elements formed according to the invention are preferably shaped as artificial concrete stones.

The invention also relates to a groove or a cobblestone strip, which is characterized in that it is composed of a large number of stone elements of the type described above. A groove or a cobblestone strip of this type is formed by means of placing, next to each other, stone elements in accordance with the invention, ensuring the size of the joint by means of the spacer or the intended joint sections. A side leakage of the material to cover dry joints filled in the joints is avoided by means of the spacers in the stone heads of the edge, which extend in the form of a ribbon practically along the entire height of the stone elements.

By placing, next to each other, the stone elements in the same direction, a groove or a cobblestone strip of this type describes a right arc or a left arc, and by means of a placement, next to each other, of the contiguous stone elements alternately in the opposite direction (alternatively a curto and long stone head), a groove that runs straight or a corresponding cobblestone strip.

In the stone element formed according to the invention, in a particularly preferred solution, the shorter length 50 of stone head to stone head is measured in such a way that the stone heads protrude on both sides respectively the same path with respect to the adjoining stone heads. In other words, the stone heads protrude on one side with the same value, and protrude on the other side with the same value, the values between the two sides being of a different size. This ensures that a placement of the stone elements can be carried out both in the same direction and in the opposite direction (alternatively, and with a 180 ° rotation) without any problem.

The invention is explained in detail in the following from examples of embodiment together with the drawing. It shows:

Figure 1. A plan view from above of two stone elements placed next to each other in the same direction;

Figure 2. A top plan view like Figure 1 with a smaller placement radius and a larger outer joint 5;

Figure 3. A plan view from above of two stone elements placed next to each other in another embodiment, in which, in this case, the stone elements are placed side by side in the opposite direction; Y

10 Figure 4. Different strips of cobblestones composed of the stone elements with a straight and curved embodiment.

The stone element 1 shown in Figure 1 in a plan view from above has a common socket (not shown), as well as three stone heads 2, 3 and 4 extending from the socket upward in the form of a rectangular , which are separated from each other by means of false joints 13. When viewed from above, the impression that these are three individual stones originates.

The three stone heads 2, 3 and 4 are arranged displaced from each other by way of a ladder, a stone head projecting or protruding respectively from the adjacent stone head. A fundamental feature 20 is given by the fact that the stone heads have in the direction of the axis of a groove that is to be placed or of a cobblestone strip that is to be placed, that is, parallel to the direction of the false joints, a different length. The stone head 2, in this case, is the one with the longest length, the stone head 3 has an average length, and the lower stone head 4 in Figure 1 is the one that is shorter. In this case, the length differences are so large that the stone heads protrude respectively on the one hand in the same dimension with respect to the adjacent stone head. In other words, on the right side of Figure 1, the stone head 3 protrudes with respect to the stone head 1 on the same path as the stone head 4 with respect to the stone head 3. This also happens in the part of the left, although in this case the size with which the stones stand out differs from that on the right side.

30

The transitions or bridges between the individual heads of the stones in the socket are shaped rounded, as shown in Figure 9.

In addition, the stone head has in the terminal regions of the lateral surfaces that run perpendicular to the axis of the stone heads of the edges 2 and 4, in each of them, a spacer 5, 6 and 10, 11 in shape slatted, the spacers being arranged on opposite lateral surfaces such that the stone elements adjacent to the spacers are brought into contact in the placed state and form a closure of the material for covering joints together in the lateral direction. Figure 1 shows how the spacers 5 and 11 are arranged offset with respect to the spacers 6 and 10, such that in the state in which they are arranged next to each other the desired side closure is achieved, as shown in Figure 1.

In addition, the stone element has on the protruding lateral surfaces, in each of them, another spacer 7, 8, which guarantees a corresponding joint distance, and in particular for the joints that run in the direction of the axis.

Four. Five

When the stone elements are placed next to each other in the manner shown in Figure 1, a curved placement with a radius of, for example, 4.0 m is automatically generated as a result of the different lengths of the stone heads. , as shown in Figure 1. In this state, the spacers 10, 11 are perfectly next to each other, and are in contact with the adjacent stone head 50. In this way a closure is formed that prevents the material for covering filled joints from being able to leave the joint laterally.

According to Figure 2, the stone elements are placed next to each other in such a way that a smaller coloring radius (R = 3.4 m) with an outer joint larger than 12 mm results. In this case, the spacers 10, 11 are in contact with each other in the outer regions only slightly, although they still retain the desired closure. Due to this, different placement radii are possible without canceling the desired closure.

Since the stone heads protrude on both sides respectively in the same dimension, they can be placed in the same direction, as shown in Figures 1 and 2, but also in the direction

inversely, as shown in Figure 3. In this case, the stone head 2 (A) of greater length of a stone element is placed next to the shorter stone head 4 (C) of the adjacent stone element, of so that as a whole it results in a cobblestone strip or a groove placed in a straight line. According to Figure 3, the two stone elements shown are represented in a limit position, in which the closure between the spacers 5, 6 is still straight.

Figure 4 shows a cobblestone strip 20 placed in straight line, and two cobblestone strips 21, 22 placed with a curvature with different placement radii. Thus, thus, the most different cobblestones or grooves can be placed with stone elements identically. As mentioned, in this case, the upper side of all the stone heads of a stone element can be shaped flat, and can form a right angle with the vertical side surfaces, so that the strips Cobblestone can be placed. The upper sides of the edge stone heads, however, can also be beveled, for example, inwardly, so that grooves can be placed.
