FR2839989A1 - Prefabricated concrete gutter module has base of cobble stones with pointed joints set in polymer matrix - Google Patents

Abstract

The gutter module (1), prefabricated from cast concrete and designed to be laid with others on a concrete bed, consists of a sloping base (2) and a raised edge (4). The base is produced by pouring a polymer matrix over cobble stones (6) with pointed joints (7) to give a cobbled effect, the pointing being slightly recessed e.g. to a depth of 2 - 3 mm. The modules are made with standardised dimensions e.g. 1.2 m long, to facilitate installation with appropriate tools.

CONCRETE CHANNEL.

  The invention relates to a channel made of concrete.

  Many streets, roads, airports, etc ... wind provided with channels intended, in known manner, to allow the evacuation of water, most often from waters

  runoff, including rainwater.

  Such wind channels generally made of concrete, and wind made up of a plurality of prefabricated unitary elements, and monoblocks, joined to each other according to their main dimensions, so as to constitute a continuous pipe.

and open to its upper surface.

  Traditionally, these gutters define a bottom, attached to a wall, substantially vertical, said bottom having a slight slope relative to the horizontal, in order to define the pipe at the level of which the water flows, and

especially rainwater.

  The objective of the present invention is to provide such a channel, thus fulfilling these essential functions, but also giving it an aesthetic appearance, and

at the same time a practical aspect.

  The gutter as defined in the invention consists of prefabricated concrete one-piece elements, joined to each other, each comprising a bottom and a

  2s border extending from one of the dimensions to said bottom.

  I1 is characterized in that the bottom is constituted by a structure molded from joined paves, defining on its upper face a plurality of elementary polygonal surfaces. According to the invention, the molded structure is produced by the courage of a matrix in

  polyurethane, giving the whole an aspect of paving.

  Advantageously, these elementary polygonal surfaces are limited by hollow 3s joints, so as to confer on the bottom an aspect of paving, the shape of paving stones.

  being able to be of any kind, in particular square.

  In addition, the bottom has a slight upward slope from the wall defining the border. The manner of carrying out the invention and the advantages which ensue therefrom will emerge more clearly from the example of realization which follows given by way of indication and not limiting in support of

attached figures.

  Figure 1 is a schematic perspective representation of the channel according to the invention. 0 Figure 2 is a schematic representation seen from above of the gutter according to the invention.

  Figure 3 is a schematic cross-sectional representation of Figure 2.

  Figures 4 and wind similar views of another embodiment of the invention. We have therefore schematically represented in relation to FIG. 1, a channel made

in accordance with the invention.

  This consists of the assembly of prefabricated monobloc elements (1) made of concrete by molding, said elements being joined to each other in order to define

the gutter.

  These are basically made up of a bottom (2), the lower face (3) of which is substantially flat, attached to a wall or border (4), extending beyond the bottom (2), each of the elements being intended to be positioned on a concrete racer

previously flows.

  According to the invention, the bottom (2) is constituted by the assembly of jointed pavers, integrated in a polyurethane matrix. In doing so, the upper face (5) of the bottom (2) has different elementary surfaces (6), in the example described in the form of a square, delimited by joints (7) of shallow depth, typically 2 to 3 mm maximum. In doing so, the upper surface of the bottom (2) is given a form of paving

particularly aesthetic.

  Each of the elementary assemblies is molded and therefore comprises a monobloc unit.

  integrating the border (4) and the bottom (2).

  Advantageously, the upper face (5) of the bottom (2) has a slightly ascending slope, from the edge (4) towards the free edge (8) of the bottom (2), as well as

  can see it in Figure 3.

  In the example represented in relation to FIGS. 1 to 3, the background presents trots

  rows of cobblestones on the upper side.

  On the other hand, in Figures 4 and 5, the same principle is retained, except that the background

  only has two rows of pavers.

  These elements are likely to be manufactured according to standard dimensions,

  s typically 1.20 m long, to facilitate installation using suitable tools.

  At the same time, the profile of the border (4) is thus produced so that it can allow, when it is positioned to delimit a lawn, to mow it without using any other material than traditional mowers, in particular wire mowers. Indeed, the wind elements positioned in such a way that the upper face of the border is situated substantially in the same plane as the lawn in question, so that it

  there is no risk of damaging the cutting blade of the mower.

  One conceives all the interest of the element in accordance with the invention, by the ease of its installation, cumulated with the aesthetic aspect and the practical side, since it is

  positioned at the edge of a lawn.

  This installation can be done very quickly, and is to be compared with the installation of traditional gutters, which firstly require the positioning of the edges one by one, then the positioning of the pavers, also one by one. , and finally their jointing. However, according to the invention, by making available elements of standardized length, integrating both edging and paving on one or more rows, these trotting operations are only reduced to one, and allows

  furthermore a great alignment facility.
