Method for dividing a road, square or path fastening with perforated concrete format and fora stones to carry out the method.

The invention relates to a method for producing a road, place or path fastening with perforated Concrete forest stones. She continues to deal with the Carrying out the process required, specially shaped Concrete blocks.

There are many different methods and types of construction for the covering and fastening of surfaces with traffic and foot traffic, ranging from conventional paving to closed concreting and covering with slabs and also perforated concrete blocks. The latter types of covering include, above all, the lattice or shaped stones made of concrete with intersecting parallel ribs or webs that leave openings between them. After laying these openings are often filled with earth and sown with grass seeds. The grass inclusions should create a living and attractive appearance of the overall surface of the occupancy entstehen.Die openings can have in the horizontal cross-sectional geometric shapes zBkreisförmig, rectangular, in particular square, they can be jweiterhin] \ according to taper conically downwards ·

The invention now has for its object to provide Hegeln for a laying method which the above-mentioned concrete blocks operated with openings having but significant advantageous differences compared to the known methods, achieved this object is achieved according to the invention characterized _t das8 to be fastened Area is first covered with shaped stones, which in a known manner with

Breakthroughs are provided, and that in these breakthroughs -. predominantly also made of concrete * cubes bsw. Filler pieces are used appropriately.

The advantages that result from this are very diverse - no only that with this type of laying an increased strength of the underlay to be driven on is achieved, the paving can also be carried out with significantly less effort in terms of technology, personnel and time * This results in considerable economic advantages. Furthermore, there are useful color interruptions on the surface possible (pedestrian crossings, hand strip effects), which, moreover, can produce aesthetic effects even with a suitable arrangement of the interruptions (Hosaic paving).

The following are the invention with reference to the drawing Process explained and details of the invention described. It show

The invention consists in the fact that in the openings 2 of these laid shaped stones 1 cube or Filling pieces 3 are used, in such a way that they the Completely fill the opening or cavity delimited by the ribs or webs 2. piece 3 be adapted in their shape to the cavity.

Breakthroughs that have a square horizontal cross-section and taper conically downwards have proven to be particularly useful laid on a sand bed 4 (shown in Figure 1). The seam is denoted by 6. The filler pieces 3 are inserted into the openings 2, with the exception of two that are still open. The arrows indicate the laying process for the cavities still to be filled.

The static states of equilibrium in the Gearat structure, i.e. in the individual parts of the 3 closed concrete block 1, are in the following The example also applies here of a molded concrete block with a square cross-section Breakthroughs 2 and with the shape of the opening tapering downwards. The filler pieces 3 are shaped accordingly, which, as Figure 2 shows, according to Art a · truncated pyramid are formed «the filler piece 3 can therefore - also in the effect on its environment, in so primarily the ribs or webs 5 opposite - are addressed as a wedge. The distribution of forces in the The overall structure perfected with the inserted filler pieces 3 can be shown on the basis of FIG.

The wheel of a heavily loaded Xiaet motor vehicle8 is indicated in FIG. 4 with P. The forces Qi and Q2 of the same magnitude acting on the Kell flanks are combined to form a resultant R "It can be seen that R must be equal and opposite in equilibrium" From the figure 4 it can also be seen that the opposing forces acting on the wedge flanks are absorbed by the webs 5, namely in the form of a horizontally acting compressive or bending stress. By appropriate dimensioning and by a reinforcement 9, they can easily withstand these stresses. This distribution of forces within the webs 3 (vertical and horizontal compressive stress), however, means a significant advantage in terms of strength behavior * compared to normal paving with paving stones and compared to fastening old fora stones without filling the openings with old solid filler

As mentioned, the filler pieces 3 are expedient Inserted properly, i.e. they fill the Hohlraua2 τοίΐ-koamen and lie old their upper (visible) surface flush with the surface of the concrete blocks 1 · £ β but there is also the possibility of dimensioning them (the filler piece) in such a way that they age their surface, among other things a little below the plane area of the forest 1 lie so that the breakthrough can be seen as a small one Would represent deepening. This procedure would dl « Increase the grip of the entire surface.

The economic advantages resulting from the rational laying garden are also present with concrete blocks, in which the openings with vertical, so don't look aaeh tapering side walls are formed, because here too the Insertion of the cubes without the cumbersome adjustment and other additional work necessary for conventional paving.

In addition, the favorable static phenomena described on the basis of FIG. 4 also occur in wedge-shaped cubes or paving stones with a square cross-section when they are laid alone, that is, without the perforated concrete block. Of course, a corresponding reciprocal arrangement is necessary for this with regard to the course dw taper.

The laying method according to the invention has the already mentioned versatile. To have advantages »The Application extends over a very wide area In addition to the already indicated use in road, The method can also be used, for example, for plate and path fastenings for fastening water ditches, embankments, lateral fastening of taxiways, for foot crossings and mosaic paving. The method according to the invention has also proven to be very useful for regulating rivers and ditches.
