Abstract

The gutter is made in sections, each with a base (17) and two vertical walls (3, 4), each covered by a metal layer (9, 9') at the top which provides protection for the edges and/or a support for a covering grille (2). The concrete reinforcement is provided by metal elements (42) which are fixed to the upper layers (9, 9') by dowels (34) and fixing screws (13) which pass through and retain the grille, and/or other elements which are welded to opposite sides of a top metal layer. The reinforcing elements are U-shaped and made to correspond to the shape of the concrete gutter section. For certain uses, eg. inside buildings, the metal layers and grille can be coated with a plastic (PVDF), making them easier to clean with a jet of water.

Description

La présente invention a trait à un caniveau en béton armé constitué d'élments de caniveau posés de façon longitudinale l'un après l'autre, chaque élément de caniveau comportant un élément de canal en béton armé et, optionnellement, une grille en métal notamment en fonte. L'invention concerne également un élément de caniveau en béton armé destiné à fabriquer un tel caniveau.The present invention relates to a reinforced concrete gutter made up of channel elements laid longitudinally one after the other, each channel element comprising a reinforced concrete channel element and, optionally, a grid made of metal, especially cast iron. The invention also relates to a reinforced concrete channel element intended to manufacture such a gutter.

La demande de brevet français 89 09456 (= FR-A-2 649 423) décrit un élément de caniveau comme mentionné ci-dessus, élément qui, ensemble avec une pluralité d'autres éléments identiques, peut être aligné longitudinalement pour former un caniveau.French patent application 89 09456 (= FR-A-2 649 423) describes an element of channel as mentioned above, element which, together with a plurality of other identical elements can be aligned longitudinally to form a gutter.

Le type d'élément de caniveau décrit dans cette demande de brevet présente l'avantage de pouvoir être utilisé sans nécessiter la coulée d'un lit de béton sur l'endroit où l'on souhaite installer un caniveau, car l'armature propre de ce caniveau est telle qu'elle produit la stabilité requise pour ce type d'installation par elle-même.The type of channel element described in this request for patent has the advantage of being able to be used without require the pouring of a concrete bed on the place where wish to install a channel, because the clean frame of this channel is such that it produces the stability required for this type of installation by itself.

Etant donné que ces éléments de caniveau peuvent être installés dans un sol naturel qui pourrait céder aux forces d'écrasement lors du passage des véhicules lourds sur ou près des caniveaux, ceci peut résulter en un déplacement non-désiré d'un ou de plusieurs éléments de caniveau et le but de la présente invention est donc de prévoir un moyen simple par lequel de telles tendances peuvent être éliminées.Since these channel elements can be installed in natural soil that could give way to crushing forces when heavy vehicles pass over or near gutters, this can result in an unwanted displacement of one or more several gutter elements and the purpose of this invention is therefore to provide a simple means by which to such tendencies can be eliminated.

Pour obtenir ce but, un caniveau selon l'invention est caractérisé en ce que l'ensemble d'éléments de caniveau comporte un moyen permettant de solliciter chaque élément de caniveau longitudinalement contre son ou ses éléments de caniveau voisins.To achieve this goal, a gutter according to the invention is characterized in that the set of channel elements comprises a means for soliciting each channel element longitudinally against its channel element (s) neighbors.

Selon la forme de réalisation, chaque élément de caniveau comporte des réservations longitudinales débouchantes permettant d'enfiler une tige ou un cable métallique axialement à travers toutes les réservations alignées de l'ensemble d'éléments de caniveau.Depending on the embodiment, each element of channel has through longitudinal reservations for threading a rod or wire rope axially across all aligned reservations in the set of gutter elements.

Cette tige (ce cable) métallique peut être fileté(e) de façon à permettre de visser deux écrous sur elle(lui) en contresens à partir de ses deux extrémités après avoir été enfilée à travers toutes les réservations longitudinales de l'ensemble d'éléments de caniveau, pour comprimer ou solliciter ces éléments de caniveau l'un contre l'autre lors du serrage des écrous. Alternativement, on peut aussi envisager l'utilisation d'un blocage fixe, sur une extrémité du cable ou de la tige et d'un seul écrou sur l'autre extrémité.This metal rod (cable) can be threaded so that allow to screw two nuts on it (him) in reverse from both ends after being strung through all longitudinal reservations of the set of elements of channel, to compress or solicit these elements of channel against each other when tightening the nuts. Alternatively, one can also consider the use of a fixed lock on one end of the cable or rod and a single nut on the other end.

Selon une autre forme de réalisation de l'invention, chaque élément de caniveau peut comporter en outre un moyen de serrage coopérant avec les moyens de serrage d'un élément de caniveau voisin, ce type de moyen de sollicitation étant présent en combinaison avec les tiges métalliques.According to another embodiment of the invention, each channel element may further comprise a cooperating clamping means with the clamping means of a neighboring channel element, this type of solicitation means being present in combination with metal rods.

Le document DE-U-89 11 111 montre déjà un élément de caniveau comportant un moyen de serrage coopérant avec le moyen de serrage d'un élément de caniveau voisin.Document DE-U-89 11 111 already shows a channel element comprising a clamping means cooperating with the clamping means of a neighboring channel element.

Dans la forme de réalisation comportant un moyen de serrage sur chaque élément de caniveau, ce moyen de serrage peut être un verrou du type porte de camion, et selon une autre forme de réalisation, le moyen de serrage prend la forme d'un cornière qui coopère avec une autre cornière, disposées latéralement des faces frontale et arrière d'un élément de caniveau.In the embodiment comprising a clamping means on each channel element, this clamping means can be a truck door type lock, and in another form of embodiment, the clamping means takes the form of an angle which cooperates with another angle, arranged laterally front and rear faces of a channel element.

Selon une autre forme de réalisation d'un moyen de serrage disposé sur chaque élément, ce moyen de serrage peut consister en deux anneaux dont chacun est disposé près de l'extrémité longitudinale d'un élément de caniveau de façon à permettre de serrer deux éléments voisins l'un contre l'autre au moyen d'un outil de serrage amovible. Cette forme de réalisation est particulièrement avantageuse car l'outil de serrage peut être utilisé uniquement pour maintenir un préserrage lors de l'application des tiges métalliques, et ensuite les outils de serrage peuvent être récupérés et seuls les deux anneaux qui sont partiellement immergés dans le béton armé resteront sur place.According to another embodiment of a clamping means disposed on each element, this tightening means may consist in two rings each of which is arranged near the end longitudinal of a channel element so as to allow clamp two neighboring elements against each other using a removable clamping tool. This embodiment is particularly advantageous because the clamping tool can be used only to maintain a pre-tightening during the application of metal rods, and then the tools tightening can be recovered and only the two rings which are partially immersed in reinforced concrete will remain on square.

Un caniveau comme décrit ci-dessus est constitué d'une pluralité d'éléments de caniveau en béton armé, qui sont alignés et optionnellement couverts par une grille métallique ou en plastique, et selon l'invention ces éléments de caniveau sont caractérisés en ce qu'ils comportent chacun au moins deux réservations longitudinales traversant la partie en béton armé sur toute sa longueur.A channel as described above consists of a plurality reinforced concrete channel elements, which are aligned and optionally covered by a metal grid or in plastic, and according to the invention these channel elements are characterized in that they each comprise at least two longitudinal reservations crossing the reinforced concrete part over its entire length.

La grille comporte des fentes qui sont essentiellement perpendiculaires à la dimension longitudinale de l'élément de caniveau et ces fentes peuvent être courbées de façon à ce que la courbe se situe dans le plan de la grille.The grid has slots which are essentially perpendicular to the longitudinal dimension of the element of channel and these slots can be curved so that the curve is in the plane of the grid.

Entre chaque groupe de deux fentes voisines, la grille comporte une barre qui présente sur sa surface supérieure au moins un élément déflecteur qui favorise l'écoulement d'un liquide traversant la grille dans lesdites fentes.Between each group of two adjacent slots, the grid has a bar which has on its upper surface at least one deflector element which promotes the flow of a liquid passing through the grid in said slots.

Un élément de caniveau selon l'invention peut comporter un élément de canal présentant deux parois verticales et un fond horizontal, chacune des parois verticales étant recouverte à son extrémité supérieure d'un profilé métallique destiné à recevoir les deux bords latéraux de la grille. Cette grille peut être fixée sur l'élément de canal par plusieurs vis qui rentrent dans les parois verticales dudit élément de canal en traversant les profilés métalliques.A channel element according to the invention may include a channel element having two vertical walls and a bottom horizontal, each of the vertical walls being covered at its upper end of a metal profile intended to receive the two side edges of the grid. This grid can be fixed to the channel element by several screws which fit into the vertical walls of said channel element crossing the metal profiles.

Chaque profilé métallique peut comporter plusieurs douilles filetées qui sont arrangées en-dessous d'une partie du profilé qui porte le bord de la grille et à un niveau correspondant avec des trous dans la grille qui sont destinés au passage des vis. Selon une forme particulière de l'invention, chaque douille est prolongée vers le bas par un ergot destiné à être soudé sur un fer d'armature de l'élément de canal. Each metal profile can have several sockets threaded which are arranged below part of the profile which brings the edge of the grid and to a level corresponding with holes in the grid which are intended for the passage of screws. According to a particular form of the invention, each socket is extended downwards by a lug intended to be welded to a reinforcing iron of the channel element.

Dans une forme particulièrement avantageuse de l'invention, les profilés métalliques peuvent comporter des parties partiellement découpées et pliées vers l'intérieur du profilé, lesdites parties servant de points d'attache par soudure entre les profilés et les éléments d'armature de l'élément de canal.In a particularly advantageous form of the invention, the metal profiles may have parts partially cut and folded towards the inside of the profile, said parts serving as attachment points by welding between the profiles and reinforcing elements of the channel element.

Selon une autre forme de réalisation de la présente invention, chaque élément de canal comporte sur sa face frontale, une excroissance profilée qui correspond à un évidement de la face arrière de façon à permettre l'emboítement entre les faces frontales et arrières des deux éléments de canal voisins.According to another embodiment of the present invention, each channel element has on its front face, a profiled protuberance which corresponds to a recess in the face rear so as to allow nesting between the faces front and back of the two neighboring channel elements.

Selon une forme de réalisation préférée de l'invention, les faces frontales et arrières des éléments de canal comportent au moins deux trous axiaux qui sont destinés à recevoir des goujons servant à l'alignement parfait des éléments de caniveau par insertion desdits goujons à la fois dans chacun des trous alignés deux à deux sur les faces frontales et arrières des deux éléments de caniveau voisins.According to a preferred embodiment of the invention, the front and rear faces of the channel elements have at at least two axial holes which are intended to receive studs used for the perfect alignment of the channel elements by insertion of said studs at the same time into each of the holes aligned in pairs on the front and back sides of the two neighboring gutter elements.

Selon une autre forme de réalisation de la présente invention, les faces intérieures des parois verticales et du fond de l'élément de canal sont recouvertes d'une feuille étanche en polymère. Cette feuille étanche peut être également résistante à la corrosion.According to another embodiment of the present invention, the inner faces of the vertical walls and the bottom of the channel element are covered with a waterproof sheet in polymer. This waterproof sheet can also be resistant to corrosion.

Avantageusement, cette feuille s'étend au-delà des faces intérieures des parois verticales et s'étend le long de toute l'interface entre l'extrémité supérieure de la paroi verticale en béton armé et entre le profilé métallique.Advantageously, this sheet extends beyond the faces interior of the vertical walls and extends along any the interface between the upper end of the vertical wall in reinforced concrete and between the metal profile.

De chaque côté de l'élément de canal, un bord latéral de la feuille étanche peut sortir au niveau de l'interface entre le béton et le profilé métallique pour permettre de relier ce bord latéral avec une autre feuille étanche disposée latéralement par rapport au caniveau. On each side of the channel element, a side edge of the waterproof sheet can come out at the interface between the concrete and the metal profile to allow this edge to be connected side with another waterproof sheet arranged laterally by compared to the gutter.

Cette feuille étanche peut être préformée par thermoformage avant d'être mise en place pour adhérer à l'intérieur de l'élément de canal, une telle préformation de la feuille étanche pouvant considérablement faciliter la production d'un élément de caniveau. Les profilés métalliques sont avantageusement en acier galvanisé, optionnellement recouvert d'un polymère du type PVDF d'un vernis teinté, ou par toute autre matière métallique ou synthétique.This waterproof sheet can be preformed by thermoforming before being put in place to adhere to the interior of the channel element, such a preformation of the waterproof sheet can considerably facilitate the production of an element of gutter. The metal profiles are advantageously made of steel galvanized, optionally covered with a PVDF type polymer a tinted varnish, or by any other metallic material or synthetic.

    • En se tournant maintenant vers la figure 1a, on distingue un élément de canal 1 comportant un fond 17 ainsi que deux parois latérales et verticales 3 et 4 qui s' étendent de part et d'autre du fond 17 vers le haut.Turning now to Figure 1a, there is a channel element 1 comprising a bottom 17 and two walls lateral and vertical 3 and 4 which extend on both sides and across from the bottom 17 up.

    Les extrémités supérieures de ces parois verticales 3 et 4 sont recouvertes chacune d'un profilé métallique 9, 9' dont les faces principales forment un épaulement qui est destiné à recevoir les bords longitudinaux d'une plaque de grille 2 de façon à ce que la surface supérieure de ladite plaque de grille 2 se trouve au niveau des parties 9a les plus hautes des profilés 9 et 9'.The upper ends of these vertical walls 3 and 4 are each covered with a metal profile 9, 9 'whose faces main form a shoulder which is intended to receive the longitudinal edges of a grid plate 2 so that the upper surface of said grid plate 2 is at level of the highest parts 9a of the sections 9 and 9 '.

    La plaque de grille 2 comporte te long de ces bords latéraux un certain nombre d'encoches 14 qui sont munies des trous 15 permettant le passage des vis 13. Sur la surface d'appui inférieur 9c des profilés métalliques 9, 9' se trouvent plusieurs trous 10 en alignement vertical avec les trous 15 de la plaque de grille 2 afin de permettre d'engager les vis 13 à travers les trous 15 dans les trous 10.The grid plate 2 has along these lateral edges a number of notches 14 which are provided with holes 15 allowing the passage of screws 13. On the bearing surface lower 9c of the metal sections 9, 9 'are located several holes 10 in vertical alignment with the holes 15 of the grid plate 2 in order to allow the screws 13 to be engaged through the holes 15 in the holes 10.

    Comme cela sera décrit plus en détail lors de la description de la figure 4, les profilés métalliques 9 et 9' comportent endessous de la surface 9c et au niveau des trous 10, des douilles filetées à l'intérieur, permettant ainsi de fixer la plaque de grille 2 sur les profilés métalliques 9 et 9' en serrant les vis 13 dans lesdites douilles. Le nombre de vis 13 et de trous 10 dans le sens longitudinal du caniveau sera déterminé de façon à obtenir la solidité désirée du caniveau.As will be described in more detail during the description of Figure 4, the metal profiles 9 and 9 'have below from the surface 9c and at the holes 10, the sockets threaded inside, allowing to fix the plate grid 2 on the metal profiles 9 and 9 'by tightening the screws 13 in said sockets. The number of screws 13 and holes 10 in the longitudinal direction of the gutter will be determined so as to obtain the desired solidity of the channel.

    La plaque de grille 2 comporte en outre une pluralité de fentes 12 qui s'étendent essentiellement perpendiculairement à la direction longitudinale de ladite plaque 2, fentes qui peuvent avoir, comme cela est indiqué en figures 1a et 1b, une forme courbée de façon à ce que la courbure reste dans le plan de la surface supérieure de la plaque 2.The grid plate 2 further comprises a plurality of slots 12 which extend essentially perpendicular to the longitudinal direction of said plate 2, slots which can have, as shown in Figures 1a and 1b, a shape curved so that the curvature remains in the plane of the upper surface of the plate 2.

    Chaque groupe de deux fentes 12 est séparé par une barre 19 et cette barre peut porter à sa surface supérieure des éléments déflecteurs 16 qui constituent des légères saillies et qui peuvent avoir des extensions dans le sens longitudinal de la plaque de grille 2 de façon à ce qu'elles couvrent essentiellement la totalité de la largeur des barres 19.Each group of two slots 12 is separated by a bar 19 and this bar can carry elements on its upper surface deflectors 16 which constitute slight projections and which may have extensions in the longitudinal direction of the grid plate 2 so that they cover essentially the entire width of the bars 19.

    Le but de la forme courbée des fentes 12 est l'agrandissement de la probabilité que des fils d'eau qui traversent ladite plaque de grille - qui va se trouver, après l'installation définitive de l'élément de caniveau 18, au niveau du sol - de tomber dans les fentes 12 au lieu de traverser la plaque de grille 2 au niveau des barres 19.The purpose of the curved shape of the slots 12 is the enlargement of the probability that water streaks crossing said plate grid - which will be found after the final installation of channel element 18, at ground level - falling into the slots 12 instead of passing through the grid plate 2 at level of bars 19.

    Puisque la forme courbée des fentes 12 ne représente pas une garantie absolue pour qu'aucun fil d'eau ne traverse la plaque 2 sans tomber dans une fente quelconque, lesdites barres 19 comportent les saillies 16 pour diriger un fil d'eau qui s'engagerait pour passer la plaque sur le dos desdites barres 19 à être dévié à gauche ou à droite pour sûrement tomber dans une des fentes 12.Since the curved shape of the slots 12 does not represent a absolute guarantee that no water stream crosses the plate 2 without falling into any slot, said bars 19 have the projections 16 to direct a stream of water which would engage to pass the plate on the back of said bars 19 to be deflected left or right to surely fall into a slots 12.

    L'élément de canal 1 comporte une surface frontale et arrière correspondant essentiellement à des coupes perpendiculaires au sens longitudinal de l'élément de caniveau, et ces coupes comportent des formations profilées 6 et 11, de façon à constituer un élément d'emboítement lors de l'assemblage longitudinal de plusieurs éléments de caniveau comme illustrés en figures 1a et 1b.Channel element 1 has a front and rear surface essentially corresponding to cuts perpendicular to the longitudinal direction of the channel element, and these sections include profiled formations 6 and 11, so that constitute a fitting element during assembly longitudinal of several channel elements as illustrated in Figures 1a and 1b.

    Les faces frontales et arrières que l'on vient de décrire comportent des trous axiaux 7 et 7' d'une extension axiale limitée, trous qui permettent l'insertion des goujons 7a et 7a' de façon à obtenir un alignement exact de la surface frontale 5 d'un élément avec la surface arrière d'un autre élément voisin après l'insertion des ergots 7a et 7a' dans les quatre trous, dont deux et deux sont chaque fois alignés longitudinalement.The front and rear faces that have just been described have axial holes 7 and 7 'of an axial extension limited, holes which allow the insertion of studs 7a and 7a ' so as to obtain an exact alignment of the front surface 5 of an element with the back surface of another neighboring element after the insertion of the pins 7a and 7a 'in the four holes, two and two of which are aligned longitudinally each time.

    Au niveau de la surface frontale se trouvent également des ouvertures 8 et 8' qui délimitent des réservations longitudinales qui traversent entièrement les éléments de caniveau dans le sens longitudinal et on comprend facilement qu'un caniveau qui est constitué par un certain nombre d'éléments de caniveau comme illustré en figures 1a et 1b comporte , après alignement, deux réservations, qui s'étendent sur toute la longueur du caniveau.Also at the front surface are 8 and 8 'openings which define reservations longitudinal which cross entirely the elements of channel in the longitudinal direction and it is easily understood that a gutter which is made up of a number channel elements as illustrated in Figures 1a and 1b comprises, after alignment, two reservations, which extend along the entire length of the gutter.

    La figure 1b montre un élément de caniveau 18 identique à celui de la figure 1a mais en état fermé, c'est-à-dire, la plaque de grille 2 a été fixée sur les extrémités supérieures des parois 3 et 4 qui sont recouvertes des profilés métalliques 9 et 9', en serrant les vis 13 comme cela a été mentionné plus haut.Figure 1b shows a channel element 18 identical to that of Figure 1a but in closed state, that is to say, the plate grid 2 was fixed on the upper ends of the walls 3 and 4 which are covered with metal sections 9 and 9 ', in tightening the screws 13 as mentioned above.

    Les têtes des vis 13 se trouvent alors dans les encoches 14 afin que l'élément de caniveau ne présente à sa surface supérieure aucune saillie qui dépasse essentiellement le niveau de la surface supérieure de la plaque de grille 2 ou les épaulements supérieurs des profilés métalliques 9 et 9'. Les déflecteurs 16, eux, dépassent cette surface légèrement comme décrit ci-dessus, ceci étant cependant un effet désiré pour les raisons mentionnées plus haut.The heads of the screws 13 are then located in the notches 14 so that the channel element has on its upper surface no protrusion which essentially exceeds the level of the upper surface of the grid plate 2 or the shoulders upper sections of metal profiles 9 and 9 '. Deflectors 16, them, slightly exceed this surface as described above, this being however a desired effect for the reasons mentioned above.

    La figure 2 montre une étape d'un assemblage de plusieurs éléments de caniveau 1a à 1e longitudinalement l'un derrière l'autre, afin de former un caniveau.Figure 2 shows a step of assembling several channel elements 1a to 1e longitudinally one behind the other, in order to form a gutter.

    Comme décrit plus haut, l'ensemble d'éléments de caniveau comporte des réservations longitudinales alignées partant des ouvertures 8 et 8' du premier élément de caniveau 1a, l'alignement de ces réservations étant obtenu par les parties profilées des faces frontales et arrières des éléments de caniveau ainsi que par les goujons 7a et 7a'.As described above, the set of channel elements has aligned longitudinal reservations starting from openings 8 and 8 'of the first channel element 1a, the alignment of these reservations being obtained by the parties profiles of the front and rear faces of the gutter as well as by studs 7a and 7a '.

    Chaque élément de caniveau 1a à 1e comporte un moyen de serrage du type verrou de porte de camion comportant près de l'extrémité d'un élément un moyen d'arrêt ou de crochet 20c', et sur l'autre extrémité de l'élément de caniveau, une boucle de fermeture 20d de façon à serrer les deux éléments de caniveau l'un contre l'autre après engagement de la boucle 20c dans le crochet 20c' suivi par le pivotement de la boucle 20c dans le sens opposé au crochet 20c'.Each channel element 1a to 1e has a clamping means truck door lock type having near the end of an element a stop or hook means 20c ', and on the other end of the channel element, a closing loop 20d so as to clamp the two channel elements together the other after engagement of the loop 20c in the hook 20c ' followed by the pivoting of the loop 20c in the opposite direction to the hook 20c '.

    Dans des situations où un maintien sous pression élevée de chaque élément de caniveau contre son ou ses voisins est exigé, on se sert des réservations longitudinales pour y enfiler des tiges ou cables métalliques 21 et 21' en les introduisant dans les ouvertures 8 et 8' de façon à ce que les deux tiges métalliques 21 et 21' s'étendent à travers tous les éléments de caniveau alignés en sortant de la face frontale du premier élément et également de la face arrière du dernier élément.In situations where high pressure maintenance of each channel element against its neighbor or neighbors is required, longitudinal reservations are used to thread metal rods or cables 21 and 21 'by introducing them into openings 8 and 8 'so that the two rods metallic 21 and 21 'extend through all the elements of channel aligned leaving the front face of the first element and also of the rear face of the last element.

    Ensuite, et comme cela est représenté plus en détail dans la figure 6, on passe des écrous 60, 60' sur les deux brins des tiges 21 et 21' sortant de la face frontale du premier élément de caniveau ainsi que des écrous identiques 60a sur les brins des tiges 21, 21' qui sortent de la surface arrière du dernier élément de caniveau et on applique une force de contrainte longitudinale en serrant les écrous 60, 60a dans le contresens contre les surfaces frontales et arrières du premier et dernier élément de caniveau respectivement.Then, and as shown in more detail in the Figure 6, we pass nuts 60, 60 'on the two strands of rods 21 and 21 'emerging from the front face of the first element channel and identical nuts 60a on the strands rods 21, 21 'which come out of the rear surface of the last channel element and a stress force is applied longitudinal by tightening the nuts 60, 60a in the wrong direction against the front and back surfaces of the first and last channel element respectively.

    On comprend facilement que le serrage des écrous 60, 60a résulte en la création d'une force de contrainte longitudinale considérablement supérieure à celle que l'on produit par la fermeture du verrou qui est disposé à chaque interface entre deux éléments de caniveau voisins.It is easily understood that the tightening of the nuts 60, 60a results by creating a longitudinal constraint force considerably greater than that produced by the closing of the lock which is arranged at each interface between two neighboring gutter elements.

    Selon l'invention il est possible d'utiliser comme moyen de sollicitation uniquement les tiges 21 et 21' avec leurs écrous 60 sans l'application des verrous 20a, 20b etc. qui permettent uniquement de maintenir un préalignement pour faciliter l'introduction des tiges 21 et 21' dans les alésages longitudinaux, verrous qui ne constituent pourtant pas un élément essentiel dans une forme d'exécution où l'on utilise le serrage par les tiges 21 et 21'.According to the invention it is possible to use as a means of stress only rods 21 and 21 'with their nuts 60 without applying the locks 20a, 20b etc. which enable only to maintain a pre-alignment to facilitate the introduction of rods 21 and 21 'in the bores longitudinal, locks which do not constitute a essential element in an embodiment where the tightening by rods 21 and 21 '.

    La figure 3 montre une perspective du profilé métallique qui repose sur l'extrémité supérieure des parois verticales et latérales de l'élément de canal 1, et ce profilé métallique 9 comporte deux surfaces horizontales, une surface supérieure 36 et une surface inférieure 37 qui sont séparées par un épaulement 38, la surface 37 et l'épaulement 38 étant destinés à venir en contact avec les bords latéraux de la plaque de grille 2 comme illustré par exemple en figure 4.Figure 3 shows a perspective of the metal profile which rests on the upper end of the vertical walls and side of the channel element 1, and this metal profile 9 has two horizontal surfaces, an upper surface 36 and a lower surface 37 which are separated by a shoulder 38, the surface 37 and the shoulder 38 being intended to come into contact with the side edges of the grid plate 2 as illustrated for example in figure 4.

    Des rabats 30 et 31 s'étendent vers le bas à partir des extrémités opposées des parties horizontales 36 et 37 afin de protéger les parties extrêmes supérieures des surfaces intérieures et extérieures des parois verticales comme cela est bien visible dans la figure 4.Flaps 30 and 31 extend downward from the opposite ends of the horizontal parts 36 and 37 in order to protect the upper extremities of surfaces interior and exterior vertical walls as is clearly visible in Figure 4.

    La partie horizontale 37 comporte à son dessous une pluralité de douilles 34 dont une seule est représentée en figure 3.The horizontal part 37 has a plurality of sockets 34 of which only one is shown in FIG. 3.

    La douille 34 qui s'étend vers le bas à partir d'un trou 10 (figure la) est filetée à l'intérieur et elle est fermée à sa partie inférieure par un ergot plein 35 qui va servir de support de soudage pour rendre solidaires la douille 34 (ensemble avec les vis 13 - figure 1 - qu'elle va recevoir) avec un élément d'armature métallique 42 (figure 4). The socket 34 which extends downwards from a hole 10 (figure la) is threaded inside and closed at its lower part by a solid lug 35 which will serve as a support welding to secure the socket 34 (together with the screws 13 - figure 1 - which it will receive) with an element of metallic reinforcement 42 (FIG. 4).

    On a trouvé avantageux d'utiliser l'ergot 35 comme support de ce soudage plutôt que la douille 34 elle-même car des déformations thermiques de la douille 34 pourraient arriver lors du soudage, compromettant ainsi l'engagement complet des vis 13 jusqu'au fond de la douille afin de serrer fiablement la plaque de grille 2 contre la partie horizontale 37 du profilé 9.It has been found advantageous to use lug 35 as a support for this. welding rather than the socket 34 itself because of deformations of the socket 34 could happen during welding, thus compromising the complete engagement of the screws 13 up to socket bottom to securely tighten the grid plate 2 against the horizontal part 37 of the profile 9.

    Suivant son extension longitudinale du profilé 9, une pluralité de douilles 34 est arrangée en-dessous des trous 10 pour servir de réceptacle des vis 13 qui sont réparties sur la longueur de la plaque de grille 2.Depending on its longitudinal extension of the profile 9, a plurality of sockets 34 is arranged below the holes 10 to serve receptacle for the screws 13 which are distributed over the length of the grid plate 2.

    Les rabats 30 et 31 comportent également réparti sur l'extension longitudinale du profilé 9, un certain nombre de parties 32 et 33 partiellement coupées et pliées vers l'intérieur du profilé 9, parties 32 et 33 qui serviront comme cela est indiqué dans la partie gauche de la figure 4, de support pour effectuer une connexion mécanique par soudage entre le profilé 9 et les barres d'armature 40 et 41 qui traversent l'élément de canal 1 en forme d'arceau de façon similaire à la barre 42 qui se trouve soudée sur l'ergot 35.The flaps 30 and 31 also have distributed over the extension longitudinal section 9, a number of parts 32 and 33 partially cut and folded towards the inside of the profile 9, parts 32 and 33 which will be used as indicated in the left part of Figure 4, support for performing a mechanical connection by welding between profile 9 and bars of reinforcement 40 and 41 which pass through the channel element 1 in the form of bar in a similar way to the bar 42 which is welded on lug 35.

    La figure 4 dont la partie droite montre une coupe transversale au niveau des vis 13, alors que la partie gauche montre une coupe au niveau des parties coupées 32 et 33 des rabats 30, 31 du profilé 9, indique clairement que l'élément de caniveau comporte un encerclement métallique constitué de la barre 42, l'ergot 35, les douilles 34, vis 13 et la plaque 2 aux mêmes intervales que l'on trouve les vis 13 dans les plaques de grille, alors qu'il comprend un deuxième et troisième encerclement partiel formé par les barres 40 et 41 qui se trouvent soudées au profilé métallique. Les ouvertures 8 et 8' ne sont pas montrées dans la figure 4.Figure 4, the right part of which shows a cross section at the level of the screws 13, while the left-hand part shows a cut at the cut parts 32 and 33 of the flaps 30, 31 profile 9, clearly indicates that the channel element has a metal surround consisting of the bar 42, lug 35, sockets 34, screws 13 and plate 2 at the same that we find the screws 13 in the plates grid, while it includes a second and third partial encirclement formed by bars 40 and 41 which are are welded to the metal profile. The openings 8 and 8 'are not shown in Figure 4.

    Alternativement, on peut aussi prévoir de créer des éléments d'ancrage par poinçonnement d'une partie 32a qui représente un rectangle coupé le long de trois de ses quatre côtés, et replié vers l'intérieur. L'élément 32a se situe complètement à l'intérieur des rabats 30 et 31 et ne présente aucune intersection avec le bord libre 32b de ce rabat.Alternatively, we can also plan to create elements anchoring by punching a part 32a which represents a rectangle cut along three of its four sides, and folded towards the inside. Element 32a is located completely inside the flaps 30 and 31 and has no intersection with the free edge 32b of this flap.

    Le soudage du profilé métallique 9 sur les barres 40 et 41 est indépendant du placement dans le sens longitudinal des vis 13, et te nombre des barres 40, 41 qui sont réparties sur une certaine longueur de l'élément de caniveau est indépendant du nombre d'encerclements suivant la position des vis 13. Cette triple fixation du profilé métallique 9, 9' sur l'armature intérieure de l'élément de canal 1 garantie une assise et un maintien parfaits entre le profilé métallique et l'extrémité supérieure en béton des parois verticales 3 et 4 de façon à garantir au maximum le maintien de l'intégralité entre la plaque de grille 2 et les parois verticales 3 et 4.The welding of the metal profile 9 on the bars 40 and 41 is independent of the placement in the longitudinal direction of the screws 13, and the number of bars 40, 41 which are distributed over a certain length of the channel element is independent of the number of encirclements according to the position of the screws 13. This triple fixing of the metal profile 9, 9 'to the frame interior of channel element 1 guarantees a seat and perfect support between the metal profile and the end concrete top of vertical walls 3 and 4 so that guarantee as much as possible the integrity between the plate grid 2 and the vertical walls 3 and 4.

    La figure 5a montre un exemple d'exécution du verrou situé entre deux éléments de caniveau voisins comme cela a été déjà mentionné lors de la description de la figure 2, ce verrou comportant du côté de l'extrémité d'un premier élément de caniveau 1b, un crochet 50 et, fixée sur l'extrémité opposée d'un élément de caniveau voisin une boucle 52 qui est fixée en pivotement sur cet élément de caniveau voisin 1a au moyen de deux anneaux 54.Figure 5a shows an example of execution of the lock located between two neighboring gutter elements as has already been mentioned during the description of figure 2, this lock comprising on the end side a first element of channel 1b, a hook 50 and, fixed on the opposite end of a neighboring channel element a loop 52 which is fixed in pivoting on this neighboring channel element 1a by means of two rings 54.

    La boucle 52 peut être pivotée autour de sa partie qui est maintenue par les anneaux 54, et les deux branches longitudinales de la boucle 52 comportent des trous 53 permettant le passage d'une deuxième boucle 51 qui s'engage d'autre part dans les crochets 50.The loop 52 can be pivoted around its part which is held by the rings 54, and the two branches longitudinal of the loop 52 have holes 53 allowing the passage of a second loop 51 which engages on the other hand in the hooks 50.

    La figure 5b montre une autre forme de réalisation du moyen de serrage. Deux cornières 77 sont fixées en contresens sur les extrémités latérales de deux éléments de canal 1a et 1b de façon à pouvoir coopérer par vissage d'un boulon 57 qui traversera les trous 59 pratiqués dans les deux parties perpendiculaires 56 des cornières. FIG. 5b shows another embodiment of the means of Tightening. Two angles 77 are fixed in opposite directions on the lateral ends of two channel elements 1a and 1b so to be able to cooperate by screwing a bolt 57 which will pass through the holes 59 made in the two perpendicular parts 56 of angles.

    Les parties 55 sont de préférence soudées sur des éléments d'armature intérieure des éléments de canal 1a et 1b par l'intermédiaire des parties qui pénètrent dans le béton.The parts 55 are preferably welded to elements of internal reinforcement of channel elements 1a and 1b by through the parts that penetrate the concrete.

    Les moyens de serrage selon les figures 5a et 5b, comme déjà mentionné, peuvent servir pour maintenir les éléments de caniveau dans leur position mutuelle, mais aussi et surtout, ils peuvent servir pour obtenir un rapprochement parfait de deux éléments après leur pose grossière.The clamping means according to FIGS. 5a and 5b, as already mentioned, can be used to maintain the elements of gutter in their mutual position, but also and above all, they can be used to get a perfect match of two elements after their rough installation.

    On peut facilement comprendre que ces éléments, qui ont un poids considérable, se posent d'abord soit par une grue ou manuellement à l'aide d'un moyen porteur de façon approximativement alignée, et ensuite on procède à l'alignement parfait et serré en utilisant le moyen de serrage décrit ci-dessus.We can easily understand that these elements, which have a weight considerable, arise first either by a crane or manually using a carrier means so approximately aligned, and then we proceed to alignment perfect and tight using the tightening means described above.

    La figure 6 montre l'interface entre deux extrémités s'opposant des deux éléments de caniveau 1a et 1b voisins qui sont maintenus dans leur position relative par un verrou fermé comme décrit plus en détail en se référant à la figure 5, après les avoir alignés auparavant par l'emboítement de leurs parties profilées 6 et 11.Figure 6 shows the interface between two opposing ends of the two adjacent channel elements 1a and 1b which are held in their relative position by a closed lock as described in more detail with reference to Figure 5, after the have aligned before by the nesting of their parts profiles 6 and 11.

    Pour des raisons de clarté, les plaques de grille 2a et 2b ont été désignées sans détail de leurs structures de fentes et barres, les bords latéraux longitudinaux de ces plaques représentent sur les parties horizontales inférieures des profilés métalliques 9a, 9b et 9a', 9b'.For reasons of clarity, the grid plates 2a and 2b have been designated without details of their slot structures and bars, the longitudinal side edges of these plates represent on the lower horizontal parts of metal profiles 9a, 9b and 9a ', 9b'.

    Des tiges métalliques (cables) 21, 21' ont été passées au travers des réservations longitudinales décrites plus en détail en se référant aux figures précédentes, et des écrous 60, 60', 60a sont désignés avant leur engagement sur les tiges 21, 21'.Metal rods (cables) 21, 21 'have been passed through through longitudinal reservations described in more detail with reference to the previous figures, and nuts 60, 60 ', 60a are designated before their engagement on the rods 21, 21 '.

    Les éléments de canal 1a et 1b comportent à leur surface intérieure un revêtement étanche 61 qui couvre l'intégralité des surfaces intérieures du fond et des parois verticales dudit élément de canal, ce revêtement étanche 61 s'étendant en outre, de chaque côté 62, entre la partie supérieure de la paroi verticale et entre le profilé métallique 9a, 9a' afin de ressortir en 63 vers l'extérieur en-dessous des rabats latéraux 31 comme illustré dans la figure 3.The channel elements 1a and 1b have on their surface interior a waterproof coating 61 which covers all of the interior surfaces of the bottom and vertical walls of said channel element, this waterproof coating 61 further extending, on each side 62, between the upper part of the vertical wall and between the metal profile 9a, 9a 'so as to come out at 63 outward below the side flaps 31 as illustrated in figure 3.

    Le revêtement 61 adhère parfaitement contre les surfaces intérieures des parties en béton 64 que constituent le fond et les parois verticales de l'élément de canal et rend cet élément de canal étanche.The coating 61 adheres perfectly against the surfaces interior of the concrete parts 64 which constitute the bottom and the vertical walls of the channel element and makes this element of waterproof channel.

    Une telle disposition d'un revêtement étanche et optionnellement résistant à la corrosion peut être prévu pour des applications spéciales d'un caniveau qui devrait conduire des liquides qui pourraient avoir un effet néfaste vis-à-vis du béton.Such an arrangement of a waterproof coating and optionally corrosion resistant can be provided for applications special of a channel which should conduct liquids which could have a detrimental effect on concrete.

    Au niveau de l'interface entre deux éléments de caniveau 1a et 1b, on obtient évidemment une rupture de ce revêtement étanche, rupture qui pourra être scellée en créant un cordon de soudage avec apport du même matériau que celui du revêtement 61.At the interface between two channel elements 1a and 1b, there is obviously a rupture of this waterproof coating, rupture which can be sealed by creating a weld bead with the same material as that of the coating 61.

    Un tel soudage se fait évidemment avant la fermeture du caniveau par l'ensemble des plaques de grilles 2a, 2b, etc, soudage qui peut être précédé par la déposition d'un fil métallique dans la fente qui est créée entre les deux revêtements 61 des éléments de caniveau voisins, fil métallique qui pourra servir ultérieurement pour la vérification de la qualité du soudage en cherchant un claquage électrique entre ce fil et une sonde de contrôle que l'on passe manuellement le long de ladite soudure.Such welding is obviously done before closing the channel by the set of grid plates 2a, 2b, etc., welding which may be preceded by the deposition of a metal wire in the slot which is created between the two coverings 61 of the elements of neighboring gutter, metal wire that can be used later for the verification of the quality of the welding in looking for an electrical breakdown between this wire and a probe control that is passed manually along said weld.

    Les parties 63 du revêtement étanche sortant latéralement des parois verticales de l'élément de canal 1a ou 1b, peuvent servir pour effectuer une connexion étanche avec un autre revêtement étanche ou une couche étanche qui sera ou qui a été déposé auparavant sur ou dans le sol voisin afin d'obtenir une étanchéité complète de la surface du sol dans un certain endroit. The parts 63 of the waterproof coating leaving laterally vertical walls of channel element 1a or 1b, can be used to make a waterproof connection with another coating waterproof or a waterproof layer that will be or has been deposited previously on or in the neighboring soil in order to obtain a complete sealing of the soil surface in a certain place.

    Une contrainte axiale entre les divers éléments de caniveau est particulièrement avantageuse pour les éléments portant des couches étanches scellées entre les éléments, pour assurer leur immobilité relative.An axial stress between the various channel elements is particularly advantageous for elements bearing sealed layers sealed between the elements, to ensure their relative immobility.

    Les figures 7a, 7b et 7c montrent plusieurs étapes de la formation du revêtement étanche 61 de la figure 6, et on comprend que ce revêtement 61 est constitué par une structure semirigide d'un matériau polymère ou autre que l'on trouve sur le marché sous forme de feuille ou de plaque.Figures 7a, 7b and 7c show several stages of the formation of the waterproof coating 61 of FIG. 6, and one understands that this coating 61 is constituted by a structure semi-rigid of a polymer or other material found on the market in sheet or plate form.

    La figure 7a montre les deux parties 70 et 71 d'un moule de pressage entre lesquelles on dispose la feuille d'origine 72, moule qui comporte un positif et un négatif de la forme intérieure d'un élément de caniveau et la forme 73, 74 du profilé métallique mentionné plus haut.Figure 7a shows the two parts 70 and 71 of a mold pressing between which the original sheet 72 is placed, mold which has a positive and a negative of the form interior of a channel element and the form 73, 74 of the metal profile mentioned above.

    La partie de moule 71 comporte un épaulement 76 et la partie 70 du moule un épaulement 75 servant ensemble de ciseaux pour couper les bords de la feuille 72 lors de la fermeture complète du moule, comme illustré en figure 7b où on distingue les brins latéraux 72a constituant les bords latéraux coupés de la feuille 72'.The mold part 71 has a shoulder 76 and the part 70 of the mold a shoulder 75 serving as a set of scissors for cut the edges of sheet 72 when fully closed of the mold, as illustrated in FIG. 7b where the strands are distinguished side 72a constituting the cut side edges of the sheet 72 '.

    Pour obtenir une préformation permanente de la feuille 72', les deux parties du moule 71 et 70 sont chauffées par des moyens de chauffage intégrés non illustrés, comme cela est connu dans l'art de thermoformage.To obtain a permanent preformation of the sheet 72 ', the two parts of the mold 71 and 70 are heated by means of integrated heaters not shown, as is known in the art of thermoforming.

    Lors de la séparation des deux parties du moule 70 et 71, on obtient alors le revêtement étanche en forme de moulure semirigide que l'on peut utiliser tel quel pour la fabrication d'un élément de caniveau selon la figure 6.During the separation of the two parts of the mold 70 and 71, we then obtains the waterproof molding-like coating semi-rigid which can be used as is for manufacturing of a channel element according to FIG. 6.

    La production d'un tel élément de caniveau peut être effectuée en déposant d'abord les profilés métalliques 9a, 9a' au fond d'un moule de coulée de béton, après quoi la feuille d'étanchéité 72' de la figure 7c est posée dans le moule de façon à engager ses parties correspondantes dans les profilés métalliques. Comme illustré en figure 3, les surfaces intérieures de ces profilés métalliques comportent des parties 32, 33, 34 et 35 qui doivent traverser la feuille étanche 72' afin d'être reliées par soudage à une armature métallique qui sera déposée également dans le moule, et après avoir fait percer ces parties 32 à 35 à travers la feuille étanche 72', les différentes étapes de soudage que l'on a décrit en rapport avec la figure 4 ci-dessus sont effectuées et te moule est ensuite rempli de béton.The production of such a channel element can be carried out by first depositing the metal sections 9a, 9a 'at the bottom of a concrete casting mold, after which the sheet 72 'of Figure 7c is placed in the mold so as to engage its corresponding parts in the profiles metallic. As illustrated in Figure 3, the surfaces interior of these metal profiles have parts 32, 33, 34 and 35 which must pass through the waterproof sheet 72 ' in order to be connected by welding to a metal frame which will also be placed in the mold, and after drilling these parts 32 to 35 through the waterproof sheet 72 ', the different welding steps that have been described in connection with Figure 4 above are made and the mold is then filled with concrete.

    Le démoulage produit un élément de canal 1 comme cela a été illustré en figure 1a, élément de canal qui sera fermé par une plaque de grille 2 au moment désiré.Demolding produces a channel 1 element as was illustrated in FIG. 1a, channel element which will be closed by a grid plate 2 at the desired time.

    Les profilés métalliques 9 peuvent être constitués en acier, éventuellement galvanisé et les plaques de grille 2 sont avantageusement fabriquées en fonte.The metal profiles 9 can be made of steel, possibly galvanized and the grid plates 2 are advantageously made of cast iron.

    Pour certaines applications notamment à l'intérieur des bâtiments, un revêtement des profilés métalliques 9 ainsi que de la plaque de grille 2 en PVDF ou autre pourrait être envisagé afin de donner au caniveau une surface exposée vers le haut qui est plus lisse et dont la microstructure permet un nettoyage facile éventuellement par l'application d'un simple jet d'eau.For certain applications, particularly inside buildings, a coating of metal profiles 9 as well as grid plate 2 in PVDF or other could be considered in order to give the channel an upward exposed surface which is smoother and whose microstructure allows cleaning possibly easy by applying a simple jet of water.

    Un revêtement en PVDF ou autre peut être prévu dans une couleur quelconque qui sera en rapport avec l'intérieur du bâtiment dans lequel on a fabriqué le caniveau.PVDF or other coating may be provided in one color whatever will be related to the interior of the building in which we made the gutter.

    Un exemple de procédé d'application d'un revêtement selon l'invention sera décrit dans ce qui suit :An example of a coating application process according to the invention will be described in the following:

    Une longueur de profilé en acier galvanisé selon la figure 3 est d'abord traitée par acide pour obtenir un dérochage. Ensuite le profilé est rincé deux fois à l'eau de ville et une troisième fois à l'eau déminéralisée, et séché et dégazé à 200-210°C. A length of galvanized steel profile according to Figure 3 is first treated with acid to obtain a stain removal. Then the profile is rinsed twice with tap water and a third times with demineralized water, and dried and degassed at 200-210 ° C.

    Un traitement anticorrosion suivra le séchage et ensuite le profilé est passé à travers une cabine d'application de poudre polymérisable ou capable de former un revêtement étanche à la température du profilé, qui se situera par exemple pour une poudre de polyester entre 210 et 220°C. Un nouveau traitement de séchage/dégazage à 200-210°C finira le procédé.An anti-corrosion treatment will follow the drying and then the profile is passed through a powder application booth polymerizable or capable of forming a waterproof coating profile temperature, which will be for example for a polyester powder between 210 and 220 ° C. A new treatment of drying / degassing at 200-210 ° C will end the process.
