Abstract

The invention relates to a set of concrete slabs for laying paths, having slabs of a differing predetermined width and different lengths, each set comprising a plurality of groups, and all the slabs contained in one group being of the same width, that being of a different length, which is defined by a multiple of a unit dimension, and the sum of the length of the slabs of each group giving the same variable, which defines the path length and can be divided by the unit dimension. By means of such a set, path laying using natural stones can be copied virtually undetectably. This is the case, in particular, if, according to the invention, the set comprises from two to five groups, of which each group has a multiplicity of slabs with preferably from three to six different slab lengths. <IMAGE>

Description

(57) A construction kit of concrete slabs for laying in strips (a, b, c) of slabs of a predetermined width and different lengths consists of bundles. All plates in a bundle have the same width but different plates, determined by a multiple of the screen rate. The sum of the plate lengths of each bundle gives the same size, determining the strip length (a, b, c) and the divisible measure of the grid.

BACKGROUND OF THE INVENTION The present invention relates to a concrete slab construction kit for laying in strips of slabs of a predetermined width and different lengths.

BACKGROUND OF THE INVENTION

When laying flat natural stones, laying in strips is generally known, with boards of different widths and freely selected lengths being used in each strip. In this way, it is possible to form optically multifaceted and suitable patterns from these plates. In these known belts, it is often necessary to cut off the last strip plate to accommodate the length of the other belts in order to ensure a constant width of the laying pattern.

The imitation of laying natural stones in strips with concrete slabs is very difficult because the production of concrete slabs of the same width with free lengths does not pay off, at least for reasons of economy. The same applies to the production of concrete slabs of the same size, which are then cut to uneven lengths.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a concrete slab construction kit, by means of which the optical impression of the lining in natural stone strips can be practically completely imitated, while the production of concrete slabs is still economical. In particular, it must be ensured that such concrete slabs can be used to create laying patterns in which no special starting pieces are needed, nor is it necessary to trim them by cutting when the laying pattern has a certain width and individual strips can be formed by different combinations of concrete boards.

The essence of the invention.

This object is achieved by a concrete slab construction kit for laying in strips of slabs of a predetermined width and of different lengths, according to the invention, which is characterized in that each building slab consists of several bundles that all slabs in the bundle have the same width. however, different lengths, determined by a multiple of the screen rate, and that the sum of the plate lengths of each bundle gives the same size determining the strip length and the divisible screen rate. With such a construction kit, it is possible to make an optically hardly recognizable imitation of the laying of natural stones in strips. This imitation is particularly possible when the construction kit according to the invention consists of two to five bundles, each bundle having several plates, preferably of three to six different lengths.

Such a number of slabs of the same width in a single bundle and a limited number of slab lengths provide a large number of possible combinations by which the irregularity of the laying of natural stones in strips can be very easily imitated. problems prevent cross joints. This is particularly the case when bundles are sized for laying patterns in which boards of the same length occur several times in one bundle.

Such a kit of concrete slabs can be produced economically, since it is possible for each bundle to do with a single mold in which slabs of different lengths are located. The production of such a mold for different board lengths in today's laser cutting technique is as simple as manufacturing a mold for board of the same size.

According to a particularly preferred embodiment of the invention, the multiple of the screen rate is selected such that a combination of both even and odd as well as integer or fractional values of the plate lengths in one bundle is produced. This results in a sufficient number of different plate lengths, which always allows the formation of strips of different lengths or a pattern of laying a certain width by combining the individual plates so that no cross joints occur and cutting of the plates is eliminated. ......

The width of the beam can be chosen completely independently, but the combinability of the stones is further increased when the width also corresponds to a multiple of the grid length of the plates.

It has been found that the solution according to the invention is particularly advantageous when the construction kit consists of three bundles with a width of 14, 21 and 28 cm, the plate lengths being preferably between 1 and 2 times the width of the plates taking into account a multiple of 3.5 cm.

The solution according to the invention, that is to say the construction of concrete slab construction kits for laying in multi-layer belts, will result not only in inexpensive production of concrete slabs, but also in simple laying by bundle, the layout for laying and quantity determination is greatly simplified. With a predetermined plate width, a relatively large number of different laying patterns is allowed due to the multiple plate lengths, and the laying pattern width is also a multiple of the grid pattern so that the same strip lengths can be created by individual bundles. The shapes of the laying patterns made possible in this way have the attractiveness of laying natural stones in strips. It should be pointed out that no predetermined laying scheme is required, but each strip is freely assembled from the sheets taken from the bundle. Since the bundles are sized in terms of the number of concrete slabs and slab lengths so that a sufficient number of appropriate sizes are available, laying patterns of predetermined width can be formed without cutting and matching.

Overview of Figures in the Drawings _____ _____...................

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1A shows a laying pattern from one building kit with three different plate widths; FIG. 1B shows the same laying pattern as in FIG. 1A but subdivided into two side by side Fig. 2 shows the laying pattern according to Fig. 1 with a different plate width distribution, Fig. 3 shows the laying pattern from one construction set with only two plate widths, and Fig. 4 shows the laying pattern from the construction set with only one width boards.

DETAILED DESCRIPTION OF THE INVENTION

The laying pattern shown in FIG. 1A is composed of one construction set with bundles in strips a, b and c having three different plate widths. The bundles in the belts a and b have five different plate lengths which are a multiple of the screen rate, while the bundles in the belt c have only three different plate lengths.

With such a construction kit it is possible to lay in strips in which no cross joints occur and in which no adjustment or cutting of the edge plates is necessary. At the same time, an optical impression is laid in the strips of natural stones as required and desired.

For example, for the practical construction of a concrete slab construction kit, three bundles are provided with one slab width each of 14 &quot; and &quot; 28 &quot;

For panel widths of 3.5 cm, board lengths corresponding to κ of the following table are selected:

Table

Plate width Plate length / pitch of 3.5 cm

14 cm 14; 17.5; 21; 24 , 5; 28 21 cm 21; 24.5; 28; 31 / 5; 35; 3 8.5; 42 28 cm 28; 31.5; 35; 38 , 5; 42; 45.5; 49

For the sizes shown in this table, the grid rate was

3.5 cm adjusted for both plate width and plate length.

It will be appreciated that any desired size can be used for the width of the plates, which seems advantageous for the optical shaping of the laying pattern. The length of the plates always arises from a multiple of the grid rate

3,5 cm. When selecting the grid rate, it is preferable to ensure that as many combinations of plate lengths as possible are produced for a single beam, even and odd values as well as integer and fractional values can be used for the plate lengths.

Although only one example of a construction kit has been mentioned, a plurality of construction kits with different dimensions can be used according to the invention, depending on how it is predetermined by shaping the laying pattern.

Of the length dimensions given in the table, it is advantageous to use only the first five plate lengths in order to select the mold length for the manufacture of the plates, since this gives particular advantages for the mold. With this option it is possible to dimension the individual molds so that all plates in one mold always form one bundle with a distribution of different plate lengths such that the sum of the lengths of all plates in each individual row of different molds is the same.

This results in substantial advantages since, on the one hand, all the bundles have the same width after being produced in the molded form, and therefore a bundle of uniform width is produced for transport. This facilitates handling by a storage device having a grip width set to a uniform beam width.

Such bundles of uniform width have the additional advantage of creating an additional grid pattern pattern corresponding to this width. Therefore, it is easy to determine the number of slabs needed for the area to be laid. By placing the individual rows of bundle plates together and replacing at least two adjacent plates at the contact point in each second row, it is ensured that no cross joints occur. This measure is evident from a comparison of both Figures 1A and 1B.

The laying pattern in Fig. 1A consists of a building kit with exactly the same plates as the laying pattern in Fig. 1B, with each strip a, b and c in Fig. 1A corresponding to two adjacent strips a, b and c in Fig. 1B. In this case, the respective length is equal to the sum of the plate lengths of the mold width, i.e. the width which the bundle has removed from the mold. In order to avoid cross-joints during installation, the adjacent plates are preferably interchangeable from each other, for example in the embodiment according to FIG. 1A of rows 2, 4, 6 and 8, calculated from above.

Fig. 2 shows a laying pattern with the same belt widths, i.e. three different belt widths a, b and c as in Fig. 1A. In general, however, a plurality of strips with larger plate widths and a greater grid pattern pattern is provided.

For laying pattern of FIG. 3 are _used only two different widths 'bands a and b, whereas the embodiment .....' of Fig. 4 shows a laying pattern in which they are used only a single board with the strip width b.
