Description

Concrete paver with a polygonal or circular section The invention relates to a

concrete paver with a polygonal or circular section intended & to be laid on the squares

public roads and traffic routes.

We know concrete pavers in the most diverse forms, and they have sections of the most varied shape. Pavers are thus known provided with recesses and protrusions which fit geometrically into each other, so that these pavers can be laid on squares and traffic lanes by forming

a fixed assembly.

In important places, like for example parking spaces, places in town centers, etc., the rainwater diversion takes place thanks to the fact that at certain intervals are formed in the place of the channels. which are covered for example by a grid

metal and which lead to a network of pipes.

The aim of the present invention is therefore to create a paving stone of the type specified above which makes it possible to implement another drainage system for the surface of the squares. This also removes the covered channels,

of grids that we knew until now.

To solve the problem thus posed, we propose a concrete paving stone with a polygonal or circular section which is suitable for being laid in public places and communication routes and which is characterized by the fact that, on each of its sides, is formed at least one groove which extends longitudinally in the thickness of the paving stone so that with at least one corresponding groove of an adjacent paving stone it constitutes in the assembly a channel for the water which extends through paving, perpendicular to it and from top to bottom, emerging into the ground or into the

layer of sand.

According to a particular embodiment, the paving stone according to the invention with a polygonal section, and in particular rectangular, has grooves along its corners.

which together with the grooves constitute the corners of the adjoining

cents in the assembly ,. or with the grooves on their sides, a channel for the flow of water in the ground or in the layer of sand, Thanks to the paving stone according to the invention, the important advantage is obtained that, during the laying of the pavement, a plurality of channels automatically form between the junction edges of the pavement, which arrive through the paving, from top to bottom, in the ground or in the layer of sand. Thus, 10. the rainwater is diverted directly through the channels in the area of each individual paving stone, and it does not occur

puddles or water flow on the surface.

This is particularly advantageous when the paving of the square is laid perfectly flat and, without such formation of channels, the water stagnates in

puddles and can only be removed with great difficulty.

According to a particular embodiment, the grooves may conform in a semicircle in the sides of the paving stones to form circular channels with

corresponding grooves of the adjacent paving stones.

It is also possible to shape the grooves into a polygon to form channels with a polygonal section.

with corresponding grooves of adjacent pavers.

Finally, the paving stones may have sides with any contour and polygonal sections or

any circulars.

In what follows, the paver according to the invention is

described in more detail on embodiments

tion given by way of example and with reference to the accompanying drawings, among which: FIG. 1 represents a top view of a square embodiment of the paving stone according to the invention; - Figure 2 shows a side view of the object of Figure 1; - Figure 3 shows a top view of a paving stone according to the invention of rectangular shape;

- Figure 4 shows part of an assembly once installed which consists of rectangular and square pavers according to Figures 1 and 3; and: - Figure 5 shows a top view of another paving stone according to the invention which is produced in the form of a

double pentagon.

As can be seen in FIG. 1, the block 1 according to the invention consists of a square body with a square section. This

paving stone can be made of any concrete or mix

concrete blocks.

On the sides 2 are formed in the thickness of the

paved with grooves 3 which extend along their surface.

These grooves may have a section other than half

circle, and for example a polygonal shape.

Figure 3 shows a rectangular block, two semi-circular grooves being formed in the long sides 2. It is further seen in Figures 1 to 3 that quarter-circle grooves 4 are formed on the corners.

extending along these.

As seen in the laying diagram of Figure 4, the grooves 3, 4 are formed symmetrically on the sides or, respectively, on the corners, so that, when laying all the pavers, a a plurality of circular channels 5 originate and extend vertically up and down through the assembly into the soil or sand bed. These channels can for example be filled with fine gravel and they are used for the drainage of rainwater. In the event that blockages occur in the canals, it is possible to simply remove their content, that is to say the chippings, and the

fill with fresh and permeable chippings.

FIG. 5 represents another possible embodiment of the paving stone according to the invention. In this exemplary embodiment, it is an eight-corner block having two corners projecting inward which are located on

the axis of symmetry of the two pentagonal parts. In this

pavement are provided circular grooves 6 which are provided

gées in the middle of each side and which come to be placed next to each other during the assembly of several paving stones, so that circular channels are formed

extending into the ground or into the sand layer.
