Description
La présente invention concerne une dalle porte-grille pour avaloir deThe present invention relates to a slab rack for draining
chaussée, du type constitué par une plaque de béton de forme rectangulaire pourvue d'un évidement central circulaire pour le passage des eaux de ruissellement collectées pavement, of the type consisting of a rectangular-shaped concrete slab provided with a circular central recess for the passage of collected run-off water
vers un réceptacle inférieur formant siphon et d'au moins deux vis pour la fixation d'un cadre supportant une grille. to a lower receptacle forming siphon and at least two screws for fixing a frame supporting a grid.
On connaît des dalles préfabriquées de ce type, mais elles sont affectées à un modèle de grille bien déterminé. Autrement dit, chaque dalle ne peut recevoir qu'un seul modèle de grille. De ce fait, il est nécessaire de stocker un grand nombre de dalles différentes, si l'on veut y adapter les divers modèles de grille actuellement disponibles sur le marché, ce qui représente un coût et un volume importants. Prefabricated slabs of this type are known, but they are assigned to a well-defined grid pattern. In other words, each slab can only receive one grid pattern. Therefore, it is necessary to store a large number of different slabs, if we want to adapt the various grid models currently available on the market, which represents a significant cost and volume.
La présente invention a donc pour but principal de remédier à cet inconvénient et, pour ce faire, elle a pour objet une dalle du type susmentionné qui se caractérise essentiellement en ce que chacune des vis est associée à une bride de fixation métallique comportant une ouverture oblongue. The main object of the present invention is thus to remedy this drawback and, for this purpose, it relates to a slab of the aforementioned type which is essentially characterized in that each of the screws is associated with a metal fastening flange having an oblong opening. .
Grâce à cette disposition et au débattement possible des brides de fixation, on peut adapter sur une même dalle plusieurs types de grilles du commerce, lui conférant ainsi une certaine polyvalence. Thanks to this arrangement and the possible movement of the fastening flanges, one can adapt on the same slab several types of commercial grids, thus giving it a certain versatility.
Dans une forme de réalisation particulière de l'invention, destinée plus spécialement aux grilles de forme carrée ou rectangulaire, la dalle comporte une empreinte supérieure de forme carrée au droit de l'évidement central circulaire. In a particular embodiment of the invention, intended more specifically for square or rectangular grids, the slab comprises a square-shaped upper recess in line with the circular central recess.
Dans une variante, destinée plus spécialement aux grilles avaloirs, c'està-dire dont le cadre comporte un prolongement inférieur de forme tronconique, la dalle est pourvue d'une empreinte supérieure tronconique située dans le prolongement de l'évidement central circulaire. 25 In a variant, intended more specifically for the gates drains, that is to say whose frame has a lower frustoconical extension, the slab is provided with a frustoconical upper imprint located in the extension of the circular central recess. 25
Ainsi, avec seulement deux types de dalles, on peut pratiquement accommoder la majeure partie des grilles du marché utilisées pour cette application. Thus, with only two types of slabs, one can practically accommodate most of the grids on the market used for this application.
De préférence, l'évidement central circulaire a un diamètre inférieur au diamètre supérieur du réceptacle et comporte, sur son bord inférieur, une saillie en pointe constituant un dispositif goutte d'eau . Preferably, the circular central recess has a smaller diameter than the upper diameter of the receptacle and comprises, on its lower edge, a pointed projection constituting a water drop device.
Ainsi, on est sûr que toute l'eau de ruissellement passant par la grille tombe bien dans le réceptacle formant 10 avaloir, même si le centrage n'est pas parfait. Thus, it is certain that all the runoff water passing through the grate falls well into the drain receptacle, even if the centering is not perfect.
De préférence également, la dalle comporte deux anneaux de levage intégrés pour sa manutention. Also preferably, the slab comprises two integrated lifting rings for its handling.
Enfin, la dalle comporte avantageusement deux coins coupés, ce qui permet de l'alléger et de ne pas dépasser le 15 poids de 100 Kg imposé par la réglementation française pour assurer la manutention avec deux opérateurs. Finally, the slab advantageously comprises two cut corners, which makes it possible to lighten it and not to exceed the weight of 100 Kg imposed by French regulations for handling with two operators.
Plusieurs formes d'exécution de l'invention sont décrites ci-après à titre d'exemples, en référence aux dessins annexés dans lesquels: la figure 1 est une vue en perspective avec arrachement partiel d'une dalle de répartition installée sur un avaloir de chaussée, conforme à l'invention; la figure 2 est une vue en coupe transversale de l'ensemble représenté sur la figure 1; la figure 3 est une vue analogue à la figure 2 avec une grille en place; et la figure 4 est une vue en perspective d'une variante de réalisation de la dalle de répartition porte-grille. Several embodiments of the invention are described hereinafter by way of example, with reference to the accompanying drawings, in which: FIG. 1 is a perspective view, partially broken away, of a distribution slab installed on a throat drain; pavement, according to the invention; Figure 2 is a cross-sectional view of the assembly shown in Figure 1; Figure 3 is a view similar to Figure 2 with a grid in place; and FIG. 4 is a perspective view of an alternative embodiment of the gate-distribution distribution slab.
L'avaloir représenté sur la figure 1 se compose essentiellement d'un réceptacle inférieur cylindrique 1 en matière plastique formant siphon, constituant l'avaloir proprement dit, surmonté d'une plaque en béton 2 de forme générale carrée. Cette dalle de répartition en béton 2 est pourvue en son centre d'un évidement circulaire 3 dont le diamètre est inférieur à celui de l'ouverture supérieure 4 du réceptacle 1 et qui est normalement recouvert par une grille en fonte non représentée ici. Ainsi, les eaux de ruissellement collectées en surface tombent dans le réceptacle 1 formant siphon au travers de la grille et de l'évidement central 3 de la dalle 2. The drier shown in Figure 1 consists essentially of a cylindrical lower receptacle 1 plastic siphon forming the actual drip, surmounted by a concrete plate 2 of generally square shape. This concrete distribution slab 2 is provided in its center with a circular recess 3 whose diameter is smaller than that of the upper opening 4 of the receptacle 1 and which is normally covered by a cast iron grate not shown here. Thus, the runoff collected on the surface falls into the receptacle 1 forming a siphon through the grid and the central recess 3 of the slab 2.
Conformément à l'invention, la dalle 2 comporte deux vis 5 sur deux de ses côtés opposés, chacune de ces vis coopérant avec une bride de fixation métallique 6 munie d'une ouverture oblongue 7. Ainsi qu'on peut le voir plus clairement sur la vue en coupe de la figure 2, ces vis 5 viennent se visser dans des inserts filetés 8 noyés dans le béton constituant la dalle. According to the invention, the slab 2 comprises two screws 5 on two of its opposite sides, each of these screws cooperating with a metal fastening flange 6 provided with an oblong opening 7. As can be seen more clearly on the sectional view of Figure 2, these screws 5 are screwed into threaded inserts 8 embedded in the concrete constituting the slab.
Avec une telle disposition, il est possible de monter plusieurs types de grilles sur une même dalle, grâce au débattement procuré par les brides 6, comme illustré sur la figure 3. Dans la mesure où l'écartement entre les vis 5 le permet, il est possible d'ajuster la position de la grille, ou plus précisément du cadre 9 supportant la grille proprement dite 10 qui est prévue amovible, dans une direction parallèle à la ligne passant par les vis. Dans la direction perpendiculaire, le réglage de la position de la grille ne présente aucune difficulté et on pourra donc la positionner avec précision par rapport au bord du trottoir. With such an arrangement, it is possible to mount several types of grids on the same slab, thanks to the travel provided by the flanges 6, as shown in Figure 3. Insofar as the spacing between the screws 5 allows it, it It is possible to adjust the position of the grid, or more precisely of the frame 9 supporting the grid itself 10 which is provided removable, in a direction parallel to the line passing through the screws. In the perpendicular direction, the adjustment of the position of the grid presents no difficulty and can therefore be positioned accurately with respect to the edge of the sidewalk.
La dalle 2 représentée ici est plus spécialement destinée aux grilles 10 de forme carrée. A cet effet, elle comporte une empreinte 11 de forme carrée au droit de l'évidement central circulaire 3. Au contraire, dans la variante de réalisation représentée sur la figure 4, il est prévu une empreinte 12 de forme tronconique située dans le prolongement de l'évidement central 3. Cette dalle est en effet destinée plus spécialement aux grilles avaloirs, dans lesquelles le cadre supportant la grille comporte lui-même un prolongement inférieur de forme tronconique. The slab 2 shown here is more specifically for grids 10 of square shape. For this purpose, it comprises a square-shaped recess 11 in line with the circular central recess 3. On the contrary, in the variant embodiment shown in FIG. 4, an imprint 12 of frustoconical shape is provided in the extension of FIG. the central recess 3. This slab is in fact intended more specifically for grilles drains, wherein the frame supporting the grid itself has a lower frustoconical extension.
Ainsi, avec seulement deux types de dalles, il est possible de monter pratiquement la majeure partie des grilles utilisées sur le marché, soit au moins une vingtaine de modèles différents. Thus, with only two types of slabs, it is possible to mount almost the majority of the grids used on the market, ie at least twenty different models.
Selon une autre caractéristique de l'invention, le bord inférieur de l'évidement central 3 de la dalle 2 comporte une saillie en pointe 13 constituant un dispositif goutte d'eau . Ainsi, l'eau de ruissellement ne risque pas de tomber en dehors du réceptacle 1. According to another characteristic of the invention, the lower edge of the central recess 3 of the slab 2 comprises a pointed projection 13 constituting a water drop device. Thus, the runoff water is not likely to fall outside the receptacle 1.
Par ailleurs, la dalle 2 est pourvue sur deux de ses côtés opposés, au voisinage des vis 5, de deux anneaux de levage intégrés 14 permettant sa manutention au moyen d'un engin de levage du type grue ou analogue. Furthermore, the slab 2 is provided on two of its opposite sides, in the vicinity of the screws 5, two integrated lifting rings 14 for handling by means of a hoist type crane or the like.
Enfin, la dalle 2 comporte avantageusement deux pans coupés 15 dans les angles, ceci afin de l'alléger. La réglementation française impose en effet un poids inférieur à 100 Kg afin de permettre sa manutention par deux hommes seulement. Finally, the slab 2 advantageously comprises two cut edges 15 in the corners, in order to lighten it. French regulations impose a weight of less than 100 kg to allow handling by only two men.
