Description

Dispositif de recouvrement d'un caniveau  Covering device for a gutter
La présente invention concerne le domaine des grilles pour le recouvrement d'un caniveau. The present invention relates to the field of grids for covering a gutter.
Elle concerne en particulier un dispositif de recouvrement d'un caniveau, adapté à un usage notamment sur les chaussées d'aérodromes et d'aéroports.  It relates in particular to a covering device of a gutter, suitable for use especially on airfield pavements and airports.
Les chaussées ou autres infrastructures routière ou urbaines présentent de manière commune un caniveau, c'est-à-dire une rigole servant à l'écoulement des eaux, ou le cas échéant d'autres liquides. Afin de permettre le passage de véhicules sur les caniveaux, d'éviter leur obstruction par des objets, ou encore d'éviter qu'un piéton ne puisse trébucher dans un caniveau, il est connu de couvrir le caniveau avec une succession de grilles affleurant le niveau du sol.  Pavements or other road or urban infrastructures commonly have a gutter, that is to say a channel used for the drainage of water or, where appropriate, other liquids. In order to allow the passage of vehicles on the gutters, to avoid their obstruction by objects, or to prevent a pedestrian from tripping in a gutter, it is known to cover the gutter with a succession of grids flush with the ground level.
Le document FR2790520 présente un élément de fermeture, typiquement une succession de grilles pour un caniveau en « U », et des moyens de liaison des grilles sur le caniveau à l'aide d'un clip rapporté dans les zones d'assemblage entre deux grilles successives. FR2790520 discloses a closure element, typically a succession of grids for a channel "U", and means for connecting the grids on the channel with a clip reported in the assembly areas between two grids successive.
Néanmoins, un tel dispositif de fermeture de caniveau n'est pas adapté à certains contextes d'utilisation. Par exemple, des caniveaux sont aménagés aux abords et sur les pistes des aérodromes. Dans ce contexte, il est important qu'aucun élément ne puisse se détacher du dispositif de fermeture de caniveau et constituer un corps étranger sur la piste de l'aérodrome. Cela fait l'objet de réglementations dites « FOD » selon l'acronyme anglophone « Foreign Object Débris » ou « Foreign Object Damage ».  Nevertheless, such a channel closure device is not adapted to certain contexts of use. For example, gutters are built around and on the airfield runways. In this context, it is important that no element can be detached from the gutter closing device and constitute a foreign body on the runway of the aerodrome. This is subject to regulations called "FOD" according to the English acronym "Foreign Object Debris" or "Foreign Object Damage".
Ainsi, la fixation par clip n'est pas adaptée à la fixation de moyens de fermeture de caniveaux sur les aérodromes. En outre, il est de manière générale plus pratique pour la pose et la maintenance des grilles de caniveau de ne pas mettre en œuvre de dispositif rapporté pour leur fixation, notamment car cela évite de devoir fournir et manipuler des pièces de petites dimensions, en quantité correspondante à celle des grilles devant être posées. Thus, the fixing by clip is not suitable for fixing means of closing gutters on the aerodromes. In addition, it is generally more convenient for the installation and maintenance of gutter grates not to implement reported device for their attachment, especially since this avoids having to supply and handle small parts, in an amount corresponding to that of the grids to be laid.
Le document FR2292804 présente un revêtement, c'est-à-dire un ensemble de grilles, pour la couverture des caniveaux de chaussée d'aérodrome limitant le risque de basculement des grilles lorsqu'un véhicule passe dessus. A cette fin, des grilles sensiblement rectangulaires sont liées à leur extrémité par un ensemble de tenons dans lequel passe un axe ou mortaise, de sorte que les grilles sont articulées en pivot. Ainsi, les grilles sont fixées les unes aux autres. Néanmoins, il peut être important de pouvoir intervenir sous une grille précise de l'ensemble de grilles, sans démonter les autres grilles, et sans nécessiter le démontage de pièces séparables rapportées.  FR2292804 has a coating, that is to say a set of grids, for the cover of the aerodrome pavement gutters limiting the risk of tilting gates when a vehicle passes over. To this end, substantially rectangular grids are connected at their end by a set of tenons in which passes a pin or mortise, so that the grids are pivotally articulated. Thus, the grids are fixed to each other. Nevertheless, it may be important to be able to intervene under a precise grid of the grid assembly, without disassembling the other grids, and without the need to dismantle separate separable parts.
L'invention a ainsi pour but de proposer un dispositif comportant une succession d'éléments de recouvrement (tels que des grilles) pour le recouvrement des caniveaux, offrant un montage n'employant pas de pièces rapportées et permettant l'ouverture individuelle des éléments de recouvrement, sans nécessiter le démontage de pièces séparables du dispositif.  The object of the invention is therefore to propose a device comprising a succession of covering elements (such as grids) for covering the gutters, offering an assembly that does not use any inserts and allowing the individual opening of the elements of the gutters. recovery, without the need to dismantle separable parts of the device.
Ainsi, l'invention porte sur un dispositif de recouvrement d'un caniveau s'étendant selon une direction longitudinale, le dispositif comportant une succession d'éléments de recouvrement comportant un premier élément de recouvrement et un deuxième élément de recouvrement adjacent au premier élément de recouvrement. Le dispositif comporte en outre un premier longeron et un deuxième longeron destinés à équiper respectivement une première zone d'appui et une deuxième zone d'appui situées de part et d'autre d'une partie supérieure d'un caniveau à recouvrir. Le premier longeron comporte au moins un premier gousset et un deuxième gousset, chacun desdits goussets ménageant un charnon, chaque élément de recouvrement de la succession d'éléments de recouvrement étant sensiblement rectangulaire et comportant un pion à une première extrémité et un orifice à une deuxième extrémité longitudinalement opposée à la première extrémité. Le pion du premier élément de recouvrement traverse le charnon du premier gousset. Le pion du deuxième élément de recouvrement traverse le charnon du deuxième gousset et dépasse dudit deuxième gousset de sorte à s'engager dans l'orifice du premier élément de recouvrement. Thus, the invention relates to a device for covering a gutter extending in a longitudinal direction, the device comprising a succession of covering elements comprising a first covering element and a second covering element adjacent to the first element of recovery. The device further comprises a first spar and a second spar intended to equip respectively a first bearing zone and a second bearing zone located on either side of an upper portion of a gutter to be covered. The first spar comprises at least a first gusset and a second gusset, each of said gussets forming a knuckle, each covering element of the succession of covering elements being substantially rectangular and comprising a pin at one end and an orifice at a second end. end longitudinally opposite the first end. The pin of the first covering element passes through the knuckle of the first gusset. The pin of the second covering element passes through the knuckle of the second gusset and protrudes from said second gusset so as to engage in the orifice of the first covering element.
Ainsi, le premier élément de recouvrement est articulé en pivot par rapport au premier longeron d'une part vis-à-vis du premier gousset et d'autre part via le pion du deuxième élément de recouvrement.  Thus, the first covering member is pivotally articulated relative to the first spar on the one hand vis-à-vis the first gusset and secondly via the pin of the second covering element.
La liaison par son pion d'un élément de recouvrement vis-à-vis du premier longeron et par son orifice vis-à-vis d'un élément de recouvrement adjacent (lui-même lié au premier longeron par son pion) permet l'articulation de chaque élément de recouvrement entre eux et par rapport au premier longeron, sans mettre en œuvre de pièces rapportées, susceptibles de se séparer du dispositif. Cela est en outre obtenu avec des éléments de recouvrement tous de conception identique, liés entre eux. Il n'y a pas d'élément maître ou esclave (l'un par rapport à l'autre) dans un tel dispositif.  The connection by its pin of a covering member vis-à-vis the first spar and its orifice vis-à-vis an adjacent covering element (itself linked to the first spar by its pin) allows the articulation of each covering element between them and with respect to the first spar, without implementing any inserts, capable of separating from the device. This is further achieved with overlapping elements all of identical design, interconnected. There is no master or slave element (relative to each other) in such a device.
Le dispositif de recouvrement d'un caniveau peut comporter une succession de plus de deux éléments de recouvrement, chaque élément de recouvrement, à l'exception d'un élément de recouvrement extrémal, étant articulé en pivot d'une part vis-à-vis du premier longeron et d'autre part vis-à-vis d'un élément de recouvrement adjacent.  The covering device of a channel may comprise a succession of more than two covering elements, each covering element, with the exception of an extremal covering element, being pivotally articulated on the one hand opposite of the first spar and secondly vis-à-vis an adjacent liner element.
Par exemple des dizaines, des centaines, voire plus, d'éléments de recouvrement peuvent ainsi se succéder pour le recouvrement d'un caniveau.  For example, tens, hundreds, or more, of covering elements can thus succeed for the recovery of a gutter.
L'orifice de chaque élément de recouvrement est avantageusement ménagé dans un élément élastique pouvant être déformé pour désengager dudit orifice le pion de l'élément de recouvrement adjacent. Cela permet de retirer un élément de recouvrement du dispositif sans avoir à retirer d'autres éléments de recouvrement. L'élément élastique peut en particulier être un bras élastique transversal à la direction longitudinale d'extension du caniveau.  The orifice of each cover element is advantageously formed in a resilient element that can be deformed in order to disengage from said orifice the pin of the adjacent covering element. This makes it possible to remove a covering element from the device without having to remove other covering elements. The elastic element may in particular be an elastic arm transverse to the longitudinal direction of extension of the gutter.
Chaque élément de recouvrement peut être ajouré de sorte à former une grille.  Each covering element may be perforated so as to form a grid.
Chaque élément de recouvrement peut en outre comporter un moyen de verrouillage adapté à coopérer avec un élément du deuxième longeron de sorte à se verrouiller. Le moyen de verrouillage peut par exemple comporter un barreau élastique, l'élément du deuxième longeron avec lequel il est adapté à coopérer étant un plot en saillie, le barreau élastique étant positionné entre le plot et une surface horizontale du deuxième longeron dans une position de fermeture de l'élément de recouvrement, empêchant l'ouverture de l'élément de recouvrement, ledit barreau élastique pouvant être déformé de sorte à être désengagé du plot afin de permettre l'ouverture de l'élément de recouvrement. Each cover member may further comprise a locking means adapted to cooperate with an element of the second spar so as to lock. The locking means may for example comprise an elastic bar, the element of the second spar with which it is adapted to cooperating being a protruding stud, the elastic bar being positioned between the stud and a horizontal surface of the second spar in a closed position of the covering element, preventing the opening of the covering element, said elastic bar being able to be deformed so as to be disengaged from the stud to allow the opening of the covering element.
Le premier longeron et/ou le deuxième longeron peut être composé de plusieurs éléments de longerons mis bout à bout. Cela permet le recouvrement de caniveaux de grande longueur, par exemple de plusieurs dizaines, centaines, ou milliers de mètres.  The first spar and / or the second spar may be composed of several elements of spars placed end to end. This allows the recovery of gutters of great length, for example several tens, hundreds, or thousands of meters.
Le premier longeron et le deuxième longeron peuvent présenter un profil en L.  The first spar and the second spar can have an L profile.
Chaque charnon peut présenter une forme oblongue orientée verticalement, et l'orifice de chaque élément de recouvrement peut présenter une forme oblongue orientée sensiblement verticalement lorsque l'élément de recouvrement est dans une position d'ouverture dans laquelle il est sensiblement vertical et en appui sur le premier longeron, de sorte que l'élément de recouvrement est bloqué en rotation dans sa position d'ouverture, le déblocage en rotation afin d'en assurer la fermeture étant obtenu en soulevant ledit élément de recouvrement du premier longeron avant de le basculer.  Each knuckle may have an oblong shape oriented vertically, and the orifice of each covering element may have an oblong shape oriented substantially vertically when the covering element is in an open position in which it is substantially vertical and resting on the first spar, so that the cover member is locked in rotation in its open position, the unlocking in rotation to ensure closure being obtained by lifting said cover member of the first spar before tilting.
Chaque élément de recouvrement est avantageusement monobloc. Each covering element is advantageously monobloc.
Chaque élément de recouvrement peut par exemple être en fonte GS. Le premier longeron et le deuxième longeron peuvent être en acier galvanisé. Each covering element may for example be cast iron GS. The first spar and the second spar can be galvanized steel.
L'invention porte également sur un ensemble comportant un caniveau et un dispositif de recouvrement tel que précédemment décrit.  The invention also relates to an assembly comprising a gutter and a covering device as previously described.
Dans un tel ensemble le caniveau peut comporter une section sensiblement invariante, la première zone d'appui et la deuxième zone d'appui formant un épaulement de part et d'autre d'une partie supérieure de la section du caniveau. Ainsi, la première zone d'appui et la seconde zone d'appui correspondent à des feuillures du caniveau.  In such an assembly the gutter may comprise a substantially invariant section, the first bearing zone and the second bearing zone forming a shoulder on either side of an upper portion of the section of the gutter. Thus, the first support zone and the second support zone correspond to rebates of the gutter.

La figure 1 représente un dispositif de recouvrement d'un caniveau C. Le caniveau est recouvert par des éléments de recouvrements 1 ,2,3. Sur la figure 1 , trois éléments de recouvrement 1 ,2,3 sont alignées successivement, de sorte qu'un premier élément de recouvrement 1 est adjacent à un deuxième élément de recouvrement 2, et le deuxième élément de recouvrement est adjacent au premier élément de recouvrement d'une part, et à un troisième élément de recouvrement 3 d'autre part. FIG. 1 represents a device for covering a channel C. The channel is covered by covering elements 1, 2, 3. In FIG. 1, three covering elements 1, 2, 3 are successively aligned, so that a first covering element 1 is adjacent to a second covering element 2, and the second covering element is adjacent to the first covering element. recovery on the one hand, and a third covering element 3 on the other.
Les éléments de recouvrement 1 ,2,3 sont identiques dans l'exemple de mode de réalisation ici représenté. Un premier longeron 4 est installé au niveau d'une feuillure du caniveau C. Un deuxième longeron 5 est installé en regard, au niveau de la feuillure opposée du caniveau C. The covering elements 1, 2, 3 are identical in the exemplary embodiment shown here. A first spar 4 is installed at level of a channel rebate C. A second spar 5 is installed opposite, at the level of the opposite rabbet of the gutter C.
Les longerons 4,5 présentent de préférence une forme générale en L (ou de cornière), c'est à dire qu'ils se présentent chacun sous la forme d'un profilé droit dont la section comporte deux plans orthogonaux. Les longerons sont disposés respectivement dans une première zone d'appui C1 et une deuxième zone d'appui C2 du caniveau C, la première zone d'appui C1 et la seconde zone d'appui C2 étant formées par les feuillures de part et d'autre des bords supérieurs du caniveau C. La zone première zone d'appui C1 et la seconde zone d'appui C2 du caniveau C sont avantageusement conformées pour accueillir les longerons 4, 5. Ainsi, les longerons 4, 5 présentant une forme générale en L sont accueillis dans un des zones d'appui C1 , C2 comportant une face horizontale et une face verticale de dimensions correspondantes à chacune des faces externes des longerons. Les dimensions des zones d'appui C1 et C2 peuvent néanmoins être supérieures à celles des longerons 4, 5, afin de permettre leur scellement dans lesdites zones d'appui C1 , C2, c'est-à-dire dans les feuillures du caniveau C. Le caniveau C présentant une section sensiblement rectangulaire, ou à tout le moins deux parois verticales, les zones d'appui C1 , C2 forment un épaulement en haut de la section du caniveau. Le caniveau peut avoir d'autres profils comme par exemple un demi-cercle.  The longerons 4,5 preferably have a general L-shape (or angle), that is to say that they are each in the form of a straight section whose section comprises two orthogonal planes. The longitudinal members are respectively disposed in a first bearing zone C1 and a second bearing zone C2 of the channel C, the first bearing zone C1 and the second bearing zone C2 being formed by the rebates of the part and the Another of the upper edges of the gutter C. The first support zone C1 and the second bearing zone C2 of the gutter C are advantageously shaped to accommodate the longitudinal members 4, 5. Thus, the longitudinal members 4, 5 having a generally L are accommodated in one of the support zones C1, C2 comprising a horizontal face and a vertical face of dimensions corresponding to each of the outer faces of the longitudinal members. The dimensions of the support zones C1 and C2 may nevertheless be greater than those of the longitudinal members 4, 5, in order to allow their sealing in said support zones C1, C2, that is to say in the grooves of the channel C The channel C having a substantially rectangular section, or at least two vertical walls, the bearing areas C1, C2 form a shoulder at the top of the section of the channel. The gutter may have other profiles such as a semicircle.
Les longerons 4, 5 peuvent notamment être fixés aux zones d'appui C1 , C2 par des pattes d'ancrage (non représentées), notamment du type en « queue de carpe », qui constituent des moyens d'ancrage fiables dans le béton.  The longitudinal members 4, 5 may in particular be fixed to the support zones C1, C2 by anchoring tabs (not shown), in particular of the "carptail" type, which constitute reliable anchoring means in the concrete.
Par ailleurs, l'écartement des longerons l'un par rapport à l'autre correspond, aux jeux fonctionnels près, à la largeur I d'un élément de recouvrement. Ainsi, en position fermée, les éléments de recouvrement 1 , 2, 3 prennent appui sur les longerons 4, 5, qui sont logés dans les zones d'appui C1 , C2 du caniveau C. La hauteur entre la surface d'appui horizontale offerte par les longerons 4,5 en position dans le caniveau et le niveau du sol S (ou du haut du caniveau) correspond à l'épaisseur e d'un élément de recouvrement, de sorte que la surface supérieure 1 1 d'un élément de recouvrement affleure le niveau du sol S lorsque l'élément de recouvrement recouvre le caniveau C. L'épaisseur e est définie par la distance entre la surface supérieure 1 1 de l'élément de recouvrement et des surfaces d'appui inférieures 16, destinées à prendre appui sur les longerons 4, 5. Furthermore, the separation of the longitudinal members relative to each other corresponds to the functional clearances, the width I of a covering element. Thus, in the closed position, the covering elements 1, 2, 3 are supported on the longitudinal members 4, 5, which are housed in the support zones C1, C2 of the channel C. The height between the horizontal support surface offered by the longitudinal members 4,5 in position in the gutter and the ground level S (or the top of the gutter) corresponds to the thickness e of a covering element, so that the upper surface 1 1 of an element of The cover is flush with the ground level S when the covering element covers the channel C. The thickness e is defined by the distance between the upper surface 1 1 of the covering element and the lower bearing surfaces 16, intended to bear on the longitudinal members 4, 5.
Une fois en position sur le caniveau, les éléments de recouvrement sont articulés de sorte que chaque élément de recouvrement peut être individuellement basculé entre une position fermée (dans laquelle il recouvre le caniveau C) et une position ouverte, permettant l'accès au caniveau.  Once in position on the gutter, the cover elements are hinged so that each covering element can be individually tilted between a closed position (in which it covers the channel C) and an open position, allowing access to the gutter.
Comme illustré aux figures 2 et 3, un élément de recouvrement peut présenter une forme sensiblement rectangulaire (c'est-à-dire que sa surface supérieure 1 1 est sensiblement rectangulaire de longueur L et de largeur I). A titre d'exemple la longueur L peut être de l'ordre de 500 mm, et sa largeur I peut être de l'ordre de 450 mm. L'élément de recouvrement peut être ajouré de sorte à former une grille, offrant une surface ouverte pour ravalement d'eau à évacuer via le caniveau recouvert. Des renforts 17 (par exemples des nervures) permettent de garantir une grande rigidité de l'élément de recouvrement. Un élément de recouvrement ayant les dimensions précitées peut notamment être dimensionné pour résister à une charge de 90 tonnes. Cela correspond aux spécifications le plus souvent souhaitées pour le recouvrement des caniveaux équipant les aérodromes.  As illustrated in Figures 2 and 3, a cover member may have a substantially rectangular shape (that is to say that its upper surface 1 1 is substantially rectangular length L and width I). By way of example, the length L may be of the order of 500 mm, and its width I may be of the order of 450 mm. The cover member may be perforated to form a grid, providing an open surface for the evacuation of water to evacuate through the covered gutter. Reinforcements 17 (for example ribs) make it possible to guarantee a high rigidity of the covering element. A covering element having the dimensions mentioned above can in particular be sized to withstand a load of 90 tons. This corresponds to the specifications most often desired for the recovery of gutters equipping aerodromes.
L'élément de recouvrement comporte un pion 12. Le pion est ainsi monobloc avec l'élément de recouvrement qui le comporte. L'élément de recouvrement étant sensiblement rectangulaire le pion 12 est positionné à l'une de ses extrémités longitudinales, au niveau d'un angle de l'élément de recouvrement. Le pion 12 s'étend selon la direction longitudinale, parallèlement à un grand côté de l'élément de recouvrement dans l'exemple représenté. Bien évidemment, chaque élément de recouvrement peut avoir, selon d'autres modes de réalisation de l'invention non représentés, une forme sensiblement carrée, ou présenter une forme rectangulaire dont le petit côté serait positionné longitudinalement sur le caniveau et le grand côté transversalement au caniveau.  The covering element comprises a pin 12. The pin is thus integral with the covering element which comprises it. The covering element being substantially rectangular the pin 12 is positioned at one of its longitudinal ends, at an angle of the covering element. The pin 12 extends in the longitudinal direction, parallel to a large side of the cover element in the example shown. Of course, each covering element may have, according to other embodiments of the invention not shown, a substantially square shape, or have a rectangular shape whose short side is positioned longitudinally on the gutter and the long side transversely to gutter.
L'élément de recouvrement comporte également un orifice 13. L'orifice The cover element also has a hole 13. The orifice
13 est positionné à une extrémité longitudinalement opposée à celle comportant le pion 12. Le pion et l'orifice définissent entre eux un axe (A) correspondant à l'axe de basculement de l'élément de recouvrement entre ses positions ouverte et fermée. L'orifice 13 présente une forme et des dimensions permettant l'insertion d'un pion 12 (d'un autre élément de recouvrement). 13 is positioned at an end longitudinally opposite to that comprising the pin 12. The pin and the orifice define between them an axis (A) corresponding to the axis of tilting of the covering element between its open and closed positions. The orifice 13 has a shape and dimensions allowing the insertion of a pin 12 (of another covering element).
L'orifice 13 est employé dans la liaison des éléments de recouvrement entre eux et vis-à-vis du premier longeron 4. Tel qu'illustré notamment à la figure 4, le premier longeron 4 comporte en effet plusieurs goussets, à savoir au moins un premier gousset 41 et un second gousset 42. Un gousset désigne de manière générale une plaque employée dans les assemblages métalliques. En l'occurrence, les goussets 41 , 42 sont disposés transversalement au premier longeron 4. Chaque gousset comporte un trou et forme ainsi un charnon 43, c'est- à-dire l'œil d'une charnière.  The orifice 13 is used in the connection of the overlapping elements with each other and with respect to the first spar 4. As illustrated in particular in FIG. 4, the first spar 4 comprises indeed several gussets, namely at least a first gusset 41 and a second gusset 42. A gusset generally designates a plate used in the metal assemblies. In this case, the gussets 41, 42 are arranged transversely to the first spar 4. Each gusset has a hole and thus forms a knuckle 43, that is to say the eye of a hinge.
La distance entre deux goussets correspond à la longueur L d'un élément de recouvrement, augmentée d'un jeu fonctionnel. Ainsi, chaque élément de recouvrement est positionné entre deux goussets. En particulier, le pion 12 d'un élément de recouvrement est introduit dans le charnon d'un gousset. La figure 5 illustre en particulier cet aspect. En l'occurrence le pion 12 du premier élément de recouvrement 1 est introduit dans le charnon 43 du premier gousset 41 du premier longeron 4.  The distance between two gussets corresponds to the length L of a covering element, increased by a functional clearance. Thus, each covering element is positioned between two gussets. In particular, the pin 12 of a covering element is introduced into the knuckle of a gusset. Figure 5 illustrates in particular this aspect. In this case the pin 12 of the first covering element 1 is introduced into the knuckle 43 of the first gusset 41 of the first spar 4.
Pour des caniveaux de grande longueur (un caniveau peut faire plusieurs dizaines voire plusieurs centaines de mètres), le premier longeron 4 et second longeron 5 peuvent être réalisé au moyens d'éléments de longeron mis bout à bout. Les éléments de longerons sont conformés de sorte que le dernier gousset d'un élément de longeron et le premier gousset d'un élément de longeron mis bout à bout présentent le même écartement que deux goussets successifs d'un même élément de longeron.  For gutters of great length (a gutter may be several tens or even hundreds of meters), the first spar 4 and second spar 5 can be achieved by means of spar members placed end to end. The spar members are shaped so that the last gusset of a spar member and the first gusset of a spar member placed end to end have the same spacing as two successive gussets of the same spar member.
Les éléments de recouvrement peuvent être successivement positionnés sur le caniveau C, la liaison de l'élément de recouvrement vis-à-vis du premier longeron étant assurée d'une part par le pion 12 de l'élément de recouvrement et d'autre part via le pion 12 de l'élément de recouvrement adjacent. Par exemple, la figure 6 illustre selon une vue schématique en coupe la liaison entre le premier élément de recouvrement 1 et le deuxième élément de recouvrement 2 qui lui est adjacent. Le pion 12 du deuxième élément de recouvrement 2 traverse le charnon du deuxième gousset 42 du premier longeron 4. Le pion 12 du deuxième élément de recouvrement 2 s'étend au-delà du deuxième gousset 42 et est introduit dans l'orifice 13 du premier élément de recouvrement. The covering elements can be successively positioned on the channel C, the connection of the covering element vis-à-vis the first spar being provided on the one hand by the pin 12 of the covering element and secondly via the pin 12 of the adjacent cover member. For example, Figure 6 illustrates in a schematic sectional view the connection between the first cover member 1 and the second cover member 2 adjacent thereto. The pawn 12 of the second element of overlap 2 passes through the knuckle of the second gusset 42 of the first spar 4. The pin 12 of the second covering element 2 extends beyond the second gusset 42 and is introduced into the orifice 13 of the first covering element.
Ainsi, le premier élément de recouvrement est lié au premier longeron Thus, the first covering element is linked to the first spar
4 par son pion 12 traversant le premier gousset 41 d'une part, et par le pion 12 du deuxième élément de recouvrement 2 introduit dans l'orifice 13 du premier élément de recouvrement d'autre part, ledit pion 12 du deuxième élément étant lui-même lié au premier longeron 4 par le deuxième gousset 42. 4 by its pin 12 passing through the first gusset 41 on the one hand, and by the pin 12 of the second covering element 2 introduced into the orifice 13 of the first covering element on the other hand, said pin 12 of the second element being even linked to the first spar 4 by the second gusset 42.
Ainsi, une liaison pivot est formée entre chaque élément de recouvrement et le premier longeron 4, permettant le basculement de chaque élément de recouvrement entre la position fermée et la position ouverte, et vice- versa.  Thus, a pivot connection is formed between each cover member and the first spar 4, allowing the tilting of each cover member between the closed position and the open position, and vice versa.
Dans l'exemple de mode de réalisation des éléments de recouvrement représenté, l'orifice 13 est ménagé dans un bras élastique 14. Le bras élastique 14 s'étend transversalement, ce qui offre à son extrémité libre, où l'orifice 13 est ménagé, un certain débattement longitudinal.  In the exemplary embodiment of the cover elements shown, the orifice 13 is formed in a resilient arm 14. The elastic arm 14 extends transversely, which offers at its free end, where the orifice 13 is provided , some longitudinal deflection.
Le débattement longitudinal de l'extrémité du bras élastique 14, dans la direction du pion 12, est par exemple sensiblement égal à la longueur du pion 12. Ce débattement longitudinal est défini par l'écart d entre le bras élastique 14 et le reste de l'élément de recouvrement, en l'absence de sollicitations extérieures. Le débattement, et donc l'écart d, est au moins égal à la longueur d'engagement g du pion 12 dans l'orifice 13 de l'élément de recouvrement adjacent quels que soient les jeux d'assemblage et leur répartition.  The longitudinal deflection of the end of the elastic arm 14, in the direction of the pin 12, is for example substantially equal to the length of the pin 12. This longitudinal movement is defined by the distance d between the elastic arm 14 and the rest of the covering element, in the absence of external stresses. The deflection, and thus the deviation d, is at least equal to the engagement length g of the pin 12 in the orifice 13 of the adjacent covering element whatever the assembly sets and their distribution.
Le bras élastique permet ainsi la mise en place et le retrait d'un élément de recouvrement individuel du dispositif de recouvrement de caniveau objet de la présente invention qui comporte une succession d'éléments de recouvrement. Comme illustré aux figures 7a et 7b, pour retirer un élément de recouvrement, son bras élastique est déformé (à l'aide d'un outil usuel par exemple mais de manière non limitative une pioche, un levier ou un pied de biche, comme illustré à la figure 7a) afin de réduire ou d'annuler l'écart d, ce qui permet le désengagement du pion 12 de l'élément de recouvrement adjacent de l'orifice 13 de l'élément de recouvrement considéré. Une fois le pion 12 désengagé de l'orifice 13, l'élément de recouvrement peut être soulevé vis-à-vis du premier longeron 4 (dans la position illustrée à la figure 7b), puis translaté pour désengager son pion 12 du charnon dans lequel il est introduit. The resilient arm thus allows the introduction and removal of an individual covering element of the channel covering device object of the present invention which comprises a succession of covering elements. As illustrated in FIGS. 7a and 7b, in order to remove a covering element, its elastic arm is deformed (with the aid of a conventional tool for example but in a nonlimiting manner a pickaxe, a lever or a crowbar, as illustrated in Fig. 7a) to reduce or cancel the gap thereby allowing the pin 12 to disengage from the adjacent cap member of the port 13 of the covering element under consideration. Once the peg 12 has disengaged from the orifice 13, the covering element can be raised with respect to the first spar 4 (in the position illustrated in FIG. 7b) and then translated to disengage its peg 12 from the knuckle in which it is introduced.
II est ainsi possible de retirer aisément un (ou plusieurs) élément de recouvrement en vue par exemple de son remplacement, sans avoir besoin de retirer l'ensemble des éléments de recouvrement du caniveau.  It is thus possible to easily remove one (or more) covering element for example for its replacement, without the need to remove all the cover elements of the gutter.
Le bras élastique 14 est réalisé d'un seul tenant avec le reste de l'élément de recouvrement. L'élément de recouvrement est ainsi réalisé dans un matériau ayant des propriétés élastiques adaptées. L'élément de recouvrement peut par exemple être réalisé en fonte GS (fonte à graphite sphéroïdal).  The elastic arm 14 is made in one piece with the rest of the covering element. The covering element is thus made of a material having suitable elastic properties. The covering element may for example be made of cast iron GS (spheroidal graphite cast iron).
Chaque élément de recouvrement peut être basculé entre une position fermée dans laquelle il recouvre le caniveau et une position ouverte dans laquelle l'accès au caniveau est possible. Dans la position fermée, un moyen de verrouillage est mis en œuvre pour maintenir l'élément de recouvrement vis-à- vis du deuxième longeron 5, empêchant son basculement vers la position ouverte.  Each covering element can be tilted between a closed position in which it covers the gutter and an open position in which access to the gutter is possible. In the closed position, a locking means is implemented to maintain the cover member vis-à-vis the second spar 5, preventing its tilting to the open position.
Le moyen de verrouillage comporte, dans l'exemple représenté, un barreau élastique 15. Plus précisément, chaque élément de recouvrement comporte un barreau élastique 15, sur un côté opposé au pion 12 et à l'orifice 13. Le barreau élastique 15 s'étend avantageusement longitudinalement et comporte une extrémité libre 151 , avantageusement située environ à mi- longueur de l'élément de recouvrement. Le deuxième longeron 5 comporte, au niveau de l'extrémité libre 151 du barreau élastique 15 (lorsque l'élément de recouvrement est positionné sur le caniveau C), un plot 51 en saillie ménageant un espace entre ledit plot 51 et la surface d'appui (horizontale) du deuxième longeron. L'extrémité libre 151 du barreau élastique peut se loger dans l'espace ainsi ménagé. L'extrémité libre est ainsi bloquée sous le plot en saillie, ce qui empêche le basculement de l'élément de recouvrement vers sa position d'ouverture.  The locking means comprise, in the example shown, an elastic bar 15. More specifically, each covering element comprises an elastic bar 15, on a side opposite to the pin 12 and the orifice 13. The elastic bar 15 s' Advantageously extends longitudinally and has a free end 151, preferably located about halfway the length of the cover member. The second spar 5 comprises, at the free end 151 of the elastic bar 15 (when the cover element is positioned on the channel C), a stud 51 projecting a space between said pad 51 and the surface of support (horizontal) of the second spar. The free end 151 of the elastic bar can be housed in the space thus formed. The free end is thus locked under the protruding stud, which prevents the tilting of the covering element towards its open position.
Les figures 8a à 8c illustrent une séquence d'ouverture d'un élément de recouvrement. Afin d'ouvrir un élément de recouvrement, le barreau élastique peut être déformé, par exemple au moyen d'un levier, comme illustré à la figue 8a. Cela permet de désengager le barreau 8a du dessous du plot, c'est-à-dire de rapprocher l'extrémité libre 151 du reste de l'élément de recouvrement afin qu'elle n'interfère plus mécaniquement avec le plot 51 . Le barreau déformable peut ainsi être passé au-dessus du plot, comme illustré à la figure 8b. Figures 8a to 8c illustrate an opening sequence of a cover member. In order to open a covering element, the elastic bar may be deformed, for example by means of a lever, as illustrated in FIG. 8a. This makes it possible to disengage the bar 8a from below the stud, that is to say to bring the free end 151 closer to the rest of the covering element so that it no longer mechanically interferes with the stud 51. The deformable bar can thus be passed over the stud, as shown in FIG. 8b.
C'est d'ailleurs à partir de la configuration montrée à la figure 8b que l'élément de recouvrement peut être démonté comme décrit en référence aux figures 7a et 7b.  It is also from the configuration shown in Figure 8b that the covering element can be removed as described with reference to Figures 7a and 7b.
Afin de poursuivre l'ouverture de l'élément de recouvrement, ce dernier est basculé autour de l'axe (A) vers la position d'ouverture illustrée à la figure 8c.  In order to continue opening the cover member, the latter is tilted about the axis (A) to the open position illustrated in Figure 8c.
Dans l'exemple de mode de réalisation représenté, la position d'ouverture est sécurisée par la configuration du dispositif de recouvrement. En d'autres termes, il est nécessaire pour refermer l'élément de recouvrement de le soulever légèrement du premier longeron 4 pour permettre son basculement vers la position fermée. Cela peut être obtenu par l'adoption d'une forme oblongue des charnons 43, visible notamment à la figure 5. Les charnons 43 présentent en particulier une forme oblongue qui s'étend dans une direction verticale. En outre, le pion 12 est positionné vis-à-vis de la tranche la plus proche de l'élément de recouvrement, à une distance inférieure à sa distance vis-à-vis de la surface d'appui inférieure 16. Ainsi, lorsque l'élément de recouvrement est ouvert et en appui sur sa tranche, le pion 12 descend en partie basse du gousset dans lequel il est introduit. Cela empêche le basculement intempestif de l'élément de recouvrement vers sa position fermée. Pour refermer l'élément de recouvrement depuis cette position de sécurité, il faut le soulever pour amener le pion en partie haute du gousset. La fonction de sécurisation de la position d'ouverture ainsi obtenue évite tout risque de fermeture intempestive de l'élément de recouvrement.  In the exemplary embodiment shown, the open position is secured by the configuration of the overlay. In other words, it is necessary to close the cover member to lift slightly from the first spar 4 to allow it to tilt to the closed position. This can be obtained by adopting an oblong shape of the knuckles 43, visible in particular in Figure 5. The knuckles 43 have in particular an oblong shape which extends in a vertical direction. In addition, the pin 12 is positioned opposite the edge closest to the covering element, at a distance less than its distance from the lower bearing surface 16. Thus, when the covering element is open and resting on its edge, the pin 12 descends at the bottom of the gusset in which it is introduced. This prevents inadvertent tilting of the cover member to its closed position. To close the cover member from this safety position, it must be lifted to bring the pin in the upper part of the gusset. The function of securing the open position thus obtained avoids any risk of inadvertent closure of the covering element.
Bien que l'invention a été décrite en particulier en référence à un mode de réalisation dans lequel les éléments de recouvrements sont identiques, il convient de noter que les éléments de recouvrement employés peuvent être différents les uns des autres dès lors qu'ils sont de conception identique pour ce qui concerne leur chaînage, c'est-à-dire leur liaison l'un par rapport à l'autre et par rapport au premier longeron. En particulier, les éléments de recouvrement peuvent présenter des marquages différents. Les éléments de recouvrement peuvent être ajourés de manières différentes ou présenter des états de surface, striations ou motifs différents. Les éléments de recouvrement peuvent présenter des dimensions différentes dans la direction longitudinale, étant entendu que les charnons doivent être espacés entre eux en conséquence (c'est-à-dire avec espacés d'une distance adaptée à la longueur de l'élément de recouvrement devant être installé entre ces charnons). Le dispositif de recouvrement d'un caniveau ainsi développé dans l'invention permet le recouvrement d'un caniveau sans mettre en œuvre de pièces susceptibles de se séparer du dispositif, tout en permettant le démontage et de remontage de l'un quelconque des éléments de recouvrement parmi la succession d'élément de recouvrement que comporte le dispositif, ainsi que l'ouverture (ou la fermeture) de l'un quelconque des éléments de recouvrement. Although the invention has been described in particular with reference to an embodiment in which the cover elements are identical, it should be noted that the covering elements employed may be different from each other as long as they are of identical design with regard to their chaining, that is to say their connection with respect to each other and relative to the first spar. In particular, the covering elements may have different markings. The cover elements may be perforated in different ways or have different surface states, striations or patterns. The overlapping members may have different dimensions in the longitudinal direction, it being understood that the knuckles must be spaced apart accordingly (i.e. spaced apart by a distance adapted to the length of the lap member to be installed between these knuckles). The covering device of a gutter thus developed in the invention allows the recovery of a gutter without implementing parts likely to separate the device, while allowing the disassembly and reassembly of any of the elements of covering among the succession of covering element that includes the device, and the opening (or closing) of any of the covering elements.
Le dispositif développé est particulièrement adapté à un usage pour le recouvrement d'un caniveau d'aérodrome, notamment du fait de l'absence de pièce rapportée pour la fermeture ou l'articulation des éléments de recouvrement, pièces qui pourraient constituer en cas de séparation intempestive du dispositif un corps étranger, potentiellement dangereux sur un aérodrome.  The device developed is particularly suitable for use for the covering of an aerodrome channel, in particular because of the absence of an insert for closing or articulation of the covering elements, which parts could constitute in case of separation inadvertent device a foreign body, potentially dangerous on an aerodrome.
