Definitions
- the invention relates to a module and a storage module for holding tanks.
- modules are known formed of an assembly of half-storage modules by vertical stacking of the half-modules between them and by horizontal junction edge-to-edge of the half-modules adjacent.
- Such a half-module is generally made of a single piece formed of a horizontal plate-shaped grid and vertical studs which extend from a large face of the plate.
- the invention thus provides a plate and separate pads which are fixed to each other only for the realization of a half-module. It is thus possible to transport and manipulate separately the plate and the pads, thus alleviating the arduous task of the staff.
- the set of pads intended to be mounted on the plate can also be handled and transported at one time or by sub-set of pads or pad by pad according to the weight of the latter.
- a single plate allows to accommodate on its two opposite sides two sets of pads where, in the prior art, thanks to its configuration, two plates were necessary; the thickness and therefore the size of such an arrangement are reduced.
- the invention also relates to a storage module for retention basin, characterized in that it comprises two storage half-modules such as briefly exposed above which are mounted head to tail and assembled with each other by cooperation of each stud of a first half-module storage respectively with the corresponding pad of the second storage half-module and, more particularly, by cooperation of the projecting element and the through hole of each pad of a first storage half-module respectively with the through hole and the protruding element of the corresponding stud of the second storage half-module.
- This arrangement or stack of half-modules is less high, less bulky, lighter and therefore less painful to assemble than in the prior art (half-modules and conventional modules) due to the use of two large opposite faces of the plate of the first half-module.
- a storage tank half-module comprises, on the one hand, a grid-shaped plate ( figure 1a ) and, on the other hand, a plurality of pads assembled on the plate, such as the stud 30 ( figure 2a ).
- the plate 10 is provided, in its thickness, with a plurality of main through openings, for example four referenced 12a-d (having for example each a generally rectangular shape), and a multitude of secondary through openings 14.
- the main openings 12a-d each have a passage section that is very much greater than that of the secondary openings (at least in a ratio of 10).
- the main openings 12a-d are in this example arranged at the four corners of the rectangle formed by the plate leaving clear a central corridor 16, while the secondary openings 14 are mainly arranged between the main openings, in the central corridor and between two openings adjacent principal 12a-b and 12c-d.
- the plate 10 has two large opposite faces of which only the upper face 10a or first face is shown on the figure 1a .
- the plate is provided on the first face 10a of first fastening means which are located in a channel 18a-d respectively surrounding each main opening 12a-d and which follows its contour.
- the channel makes it possible to stabilize the stud which will be fixed there.
- the figure 1b shows two types of first fixing means: male means and female means which are intended to cooperate each with second complementary fastening means secured to the studs such as that of the figure 2a . It should be noted that all the fixing means present on the plate and on the pads are not necessarily used for mounting according to the plate and stud configurations envisaged.
- the channel 18a is delimited by two parallel walls vis-à-vis, one inside 18a1, defines the outline of the main opening 12a and the other, 18a2 exterior, carries the fastening means.
- the outer wall 18a2 comprises two large opposite sides and two adjacent small opposite sides. Each small side carries for example a male fastening means 20a and a female fastening means 20b. Each large side carries for example four identical fastening means 20c.
- four fixing means 20c are represented on the figure 1b but only two are used for the mounting of pads on the upper face 10a, the other two being used for the mounting of pads on the opposite face not visible here.
- the second large opposite face of the plate has a structure almost identical to that of the first face 10a.
- the stud 30 illustrated at Figures 2a and 2b comprises a base 32 and a side wall 34 which extends axially from and away from the base to an end wall 36.
- the wall 34 extends in a narrower direction towards the wall end to give the pad a generally frustoconical general shape.
- the end wall 36 is partially closed and is provided as attachment members with a projecting element 38 of axial extension which is perforated and an adjacent through hole 40.
- the projecting element 38 and the hole 40 of the stud are intended to fit respectively with the hole and the projecting element of another stud in the manner of a tenon-mortise type assembly (complementary fastening elements). one of the other).
- the projecting element 38 has for example a truncated pyramid shape and is provided with two lights 38a-b in two opposite faces and a central opening 38c at the top.
- the end wall 36 is also pierced with other openings / orifices for the flow of water.
- Two additional attachment members 40a-b (forming a retainer) are arranged in an area located inside the stud withdrawn from the through hole, at the periphery thereof and in facing relation. These bodies are intended to fit into the lights 38a-b of a projecting element 38 fitted into the hole.
- the wall 34 is profiled in a cross section so as to stiffen the stud.
- the base 32 of the stud forms a peripheral portion of which a flat zone 32a surrounds a central opening 42 communicating with the inside of the stud (seen from below the figure 2b ).
- the peripheral portion 32 is also shaped so as to form, from the plane zone 32a, an outer rim 45 rising upwards ( Fig. 2a ) and which defines with the outer wall 34 of the stud a groove 44 which borders the stud at its base.
- the outer flange 45 carries second fastening means distributed on the different sides of the flange and which are intended to cooperate with the first complementary fixing means of the plate.
- a male means 46a is for example in the form of an elastic tab ( figs 2a and 2c ) provided at its free end with a ramp 46a1 ending in a straight edge 46a2.
- This means 46a is intended to cooperate with a first complementary fastening means 20b of the plate as shown in FIG. figure 2e (partial enlarged view in perspective and in section).
- the ramp 46a1 slides on the upper edge and the vertical edge 20b1 which stops by a lower drop 20b2 forming a recess into which penetrates the elastic tab 46a.
- the upper edge 46a2 is in axial abutment against the upper edge of the recess 20b2 forming a retainer, thus preventing axial shrinkage (locking of the two complementary latching means relative to one another).
- the male means 46a are offset relative to each other on either side of a median plane passing through the short sides of the stud ( Fig. 2b ).
- the female means 46b are four in number on the long side and are intended to cooperate with the plate means 20c ( fig 1b ) as shown on the figure 2f (partial enlarged view in perspective and in section).
- the means 46b have a ramp 46b1 on their outer surface which cooperates by sliding on a complementary ramp 20c1 of the complementary means 20c which is here an elastic blade.
- the coverslip elastic 20c is shaped to include, after the ramp, a return 20c2 towards the inner wall 18a2 of the channel 18a, thus conferring on the upper part of the means 20c a triangular profile.
- the ramp 20c1 is erased when sliding above the ramp 46b1 and returns to its initial position after crossing the lower edge of the ramp by the ramp 46b1.
- the free upper edge 46b2 is thus blocked by engagement with the return 20c2 which forms an axial retaining element and prevents any axial shrinkage (locking of the two complementary snap-fastening means with respect to each other).
- Keystrokes 48a-c are provided on the long sides of the peripheral flange 45 (for example two on one side and one on the opposite side) for mounting the stud in the correct position around the opening 12a ( figure 1b ) on complementary polarizers 50a-c arranged in the channel 18a.
- the figure 3 illustrates a half-module 60 which is formed from the plate 10 ( figure 1a ) on which four studs 30 were mounted via the first and second complementary fastening means of the plate and the pads respectively.
- the pads are fixed / locked to the plate, the flat area 32a of the peripheral portion 32 of each pad is supported on the upper edge of the inner wall 18a1 of each opening 12a-d.
- the central opening 42 of each stud is thus disposed opposite each main through opening 12a-d.
- the studs 30 are arranged two by two adjacent to one of the short sides or edges of the plate 10 to leave a free space large enough for the central corridor 16 between pairs of adjacent studs.
- the pairs of salient element 38 and hole 40 of each pair of adjacent studs are mounted head to tail.
- the studs arranged along the diagonals have the same arrangement (order) of alignment of the projecting element 38 and the hole 40.
- This assembly is facilitated by the presence of the polarizers 48a-c and 50a-c.
- This assembly thus makes it possible to have only one type of half-module to assemble (only one reference to manage in stock), unlike a half-module in which the pads all have the same arrangement (order) of alignment of the projecting element and the hole.
- the half-module 60 of the figure 3 (first half-module) can thus be assembled with an identical half-module referenced 62 (second half-module) which is mounted head-to-tail from above as shown in FIG. figure 4 .
- the two half-modules 60 and 62 are easily assembled with each other by means of their matching pads fixed to each other via the complementary coupling members 38, 40 (interlocking means) of each stud.
- the assembly thus assembled / stacked is a storage module 70 in which the channel 16 can be used for the passage of an inspection tool (camera ...) or as a drain.
- the figure 5 illustrates the assembly of several half-storage modules. More particularly, four additional studs 30 are fixed under the second large face 10b of the plate 10 of the first half-module 60 of the figure 4 identical to the mounting of the pads on the first face 10a.
- a third half-module 80 identical to the half-module 60, is mounted head-to-tail and assembled with the additional pads 30 fixed to the face 10b identically to the assembly of the half-modules 60 and 62.
- the plates and the pads being manufactured separately, different materials can be used to adapt to the types of mechanical forces to which the plates are subjected (lateral forces) and the studs (axial or vertical forces) and therefore in order to optimize their mechanical characteristics.
- the plates and the pads are for example made by injection molding with a mold for the plate 10 and one for the stud 30.
- Each stud carrying the two types of fasteners with the other pads there is only a type of plot, which facilitates the management of references in stock.
- the pads 30 are thus larger than in the prior art (each pad has for example a section at the base which is 200x400mm instead of about 200x200mm in the prior art), which reduces the number of mounting operations of pads on a plate.
- the plates, on the one hand, and the pads on the other hand can be stacked separately to optimize the transport and the storage.
- the handling of the stacked elements is also facilitated because of a lower weight than in the prior art (plate and pads indissociable).
- the half-module can be transported already assembled or partially assembled.

Description
L'invention concerne un module et un demi-module de stockage pour bassin de rétention.The invention relates to a module and a storage module for holding tanks.
Dans le domaine des modules de stockage utilisés pour construire les bassins de rétention, on connait des modules formés d'un assemblage de demi-modules de stockage par empilement vertical des demi-modules entre eux et par jonction horizontale bord à bord des demi-modules adjacents.In the field of storage modules used to construct the retention basins, modules are known formed of an assembly of half-storage modules by vertical stacking of the half-modules between them and by horizontal junction edge-to-edge of the half-modules adjacent.
Un tel demi-module est généralement constitué d'une seule pièce formée d'une plaque horizontale en forme de grille et de plots verticaux qui s'étendent à partir d'une grande face de la plaque.Such a half-module is generally made of a single piece formed of a horizontal plate-shaped grid and vertical studs which extend from a large face of the plate.
De tels demi-modules sont plus particulièrement connus des documents
Ces demi-modules sont toutefois lourds et encombrants, ce qui est un inconvénient pour leur manutention, notamment pour l'assemblage des demi-modules entre eux, et également pour leur transport.These half-modules are however heavy and bulky, which is a drawback for their handling, especially for the assembly of the half-modules together, and also for their transport.
La présente invention prévoit de remédier à au moins un des inconvénients précités en proposant
un demi-module de stockage pour bassin de rétention, caractérisé en ce qu'il comprend :
- une plaque en forme de grille qui est munie d'une pluralité d'ouvertures traversantes principales et secondaires, les ouvertures principales ayant une section de passage supérieure à celle des ouvertures secondaires, la plaque étant munie sur une première de ses deux grandes faces opposées de premiers moyens de fixation situés à la périphérie des ouvertures principales,
- une pluralité de plots indépendants qui sont pourvus de deuxième moyens de fixation et qui sont montés sur la première face de la plaque en s'étendant perpendiculairement à celle-ci, chaque plot étant apte à être monté séparément des autres plots en regard d'une ouverture principale par coopération des premiers et deuxièmes moyens de fixation, la plaque étant également munie sur sa deuxième grande face opposée de premiers moyens de fixation situés à la périphérie de chacune des ouvertures principales et qui sont destinés à coopérer avec des deuxièmes moyens de fixation d'autres plots.
a half-storage module for a retention basin, characterized in that it comprises:
- a grid-shaped plate which is provided with a plurality of main and secondary through openings, the main openings having a passage section greater than that of the secondary openings, the plate being provided on a first of its two large opposite faces of first fixing means located at the periphery of the main openings,
- a plurality of independent studs which are provided with second fixing means and which are mounted on the first face of the plate extending perpendicular thereto, each stud being able to be mounted separately from the other studs facing a main opening by cooperation of the first and second fixing means, the plate being also provided on its second large opposite face with first fastening means located at the periphery of each of the main openings and which are intended to cooperate with second attachment means of other pads.
L'invention permet ainsi de disposer d'une plaque et de plots séparés qui sont fixés l'un à l'autre uniquement pour la réalisation d'un demi-module. Il est ainsi possible de transporter et de manipuler séparément la plaque et les plots, allégeant ainsi la pénibilité de la tâche du personnel. L'ensemble des plots destinés à être montés sur la plaque peut d'ailleurs être manipulé et transporté en une seule fois ou par sous-ensemble de plots ou encore plot par plot selon le poids de ces derniers. Une seule plaque permet ainsi d'accueillir sur ses deux faces opposées deux séries de plots là où, dans l'art antérieur, grâce à sa configuration, deux plaques étaient nécessaires ; l'épaisseur et donc l'encombrement d'un tel agencement sont donc réduits.The invention thus provides a plate and separate pads which are fixed to each other only for the realization of a half-module. It is thus possible to transport and manipulate separately the plate and the pads, thus alleviating the arduous task of the staff. The set of pads intended to be mounted on the plate can also be handled and transported at one time or by sub-set of pads or pad by pad according to the weight of the latter. A single plate allows to accommodate on its two opposite sides two sets of pads where, in the prior art, thanks to its configuration, two plates were necessary; the thickness and therefore the size of such an arrangement are reduced.
Selon d'autres caractéristiques possibles prises isolément ou en combinaison l'une avec l'autre :
- chaque plot comprend :
- une base comportant une partie périphérique munie des deuxièmes moyens de fixation et une ouverture centrale disposée en vis-à-vis de l'ouverture principale correspondante de la plaque,
- une paroi qui s'étend axialement depuis la partie périphérique de la base et en éloignement de celle-ci jusqu'à une paroi d'extrémité fermant partiellement le plot, la paroi d'extrémité étant pourvue d'au moins un organe d'accrochage destiné à s'accrocher avec au moins un organe d'accrochage d'un autre plot ;
- la paroi d'extrémité est pourvue à titre d'organes d'accrochage d'un élément saillant d'extension axiale qui est perforé et d'un trou traversant adjacent destiné à recevoir un tel élément saillant d'un autre plot ;
- des organes d'accrochage supplémentaires sont prévus sur l'élément saillant, d'une part, et dans une zone située à l'intérieur du plot, à la périphérie du trou traversant, d'autre part ;cet agencement permet d'avoir un seul type de plot, ce qui est avantageux pour le montage et la gestion des stocks ;
- le demi-module comprend quatre plots montés sur la première face de la plaque aux quatre coins d'un carré ou d'un rectangle, l'élément saillant et le trou de chaque plot étant disposés suivant un axe d'alignement propre au plot et les axes d'alignement des quatre plots étant tous parallèles ou alignés les uns avec les autres, l'élément saillant et le trou de chaque plot monté étant agencés suivant une disposition identique pour les plots qui sont disposés selon les deux diagonales du carré ou du rectangle ; un tel agencement des plots sur la plaque permet de n'avoir qu'un seul type de demi-module à assembler ;
- sur chacune des premières et deuxième grandes faces opposées de la plaque chaque ouverture principale est entourée d'une rigole au niveau de laquelle sont disposés les premiers moyens de fixation ;
- chaque rigole est délimitée par deux parois parallèles en vis-à-vis dont une paroi intérieure définit le contour de l'ouverture principale qu'elle entoure et l'autre paroi extérieure porte les premiers moyens de fixation ;
- la partie périphérique de la base de chaque plot est conformée de manière à constituer un rebord externe formant un retour qui s'étend en éloignement de la base et définit, avec la paroi axiale du plot, une gorge bordant le plot à sa base ;
- le rebord externe porte les deuxièmes moyens de fixation au plot ;
- chaque plot et chaque rigole sont pourvus chacun de détrompeurs permettant de monter le plot dans une position prédéterminée autour de l'ouverture centrale ;
- la plaque et les plots sont réalisés dans des matériaux différents ; il est ainsi possible d'adapter et d'optimiser les matériaux des différentes pièces (plaque et plots) en fonction de leurs contraintes d'utilisation spécifiques ;
- les plots sont fabriqués par exemple par moulage ;
- la plaque est apte à être empilée avec d'autres plaques identiques et les plots sont également empilables les uns avec les autres, notamment pour le transport ; l'empilabilité séparée des plaques et des plots améliore significativement les opérations de manutention et de transport.
- each plot comprises:
- a base having a peripheral portion provided with second attachment means and a central opening disposed opposite the corresponding main opening of the plate,
- a wall that extends axially from the peripheral portion of the base and away from it to an end wall partially closing the stud, the end wall being provided with at least one fastening member intended to hook with at least one attachment member of another stud;
- the end wall is provided as attachment members of a projecting element of axial extension which is perforated and an adjacent through hole for receiving such a projecting element of another stud;
- additional hooking members are provided on the projecting element, on the one hand, and in an area located inside the stud, on the periphery of the through-hole, on the other hand, this arrangement makes it possible to have a only type of stud, which is advantageous for assembly and inventory management;
- the half-module comprises four studs mounted on the first face of the plate at the four corners of a square or a rectangle, the projecting element and the hole of each pad being disposed along an axis of alignment proper to the stud and the alignment axes of the four pads being all parallel or aligned with each other, the projecting element and the hole of each mounted stud being arranged following an identical arrangement for the studs which are arranged along the two diagonals of the square or the rectangle; such an arrangement of the pads on the plate makes it possible to have only one type of half-module to assemble;
- on each of the first and second large opposite faces of the plate each main opening is surrounded by a channel at which are disposed the first fastening means;
- each channel is delimited by two parallel walls vis-à-vis whose inner wall defines the contour of the main opening that surrounds and the other outer wall carries the first attachment means;
- the peripheral portion of the base of each stud is shaped so as to form an outer rim forming a return which extends away from the base and defines, with the axial wall of the stud, a groove bordering the stud at its base;
- the outer flange carries the second fastening means to the stud;
- each stud and each channel are each provided with polarizers for mounting the stud in a predetermined position around the central opening;
- the plate and the pads are made of different materials; it is thus possible to adapt and optimize the materials of the different parts (plate and pads) according to their specific use constraints;
- the studs are made for example by molding;
- the plate is able to be stacked with other identical plates and the pads are also stackable with each other, especially for transport; the separate stackability of the plates and pads significantly improves the handling and transport operations.
L'invention a également pour objet un module de stockage pour bassin de rétention, caractérisé en ce qu'il comprend deux demi-modules de stockage tels que brièvement exposés ci-dessus qui sont montés tête bêche et assemblés l'un avec l'autre par coopération de chaque plot d'un premier demi-module de stockage respectivement avec le plot correspondant du deuxième demi-module de stockage et, plus particulièrement, par coopération de l'élément saillant et du trou traversant de chaque plot d'un premier demi-module de stockage respectivement avec le trou traversant et l'élément saillant du plot correspondant du deuxième demi-module de stockage.The invention also relates to a storage module for retention basin, characterized in that it comprises two storage half-modules such as briefly exposed above which are mounted head to tail and assembled with each other by cooperation of each stud of a first half-module storage respectively with the corresponding pad of the second storage half-module and, more particularly, by cooperation of the projecting element and the through hole of each pad of a first storage half-module respectively with the through hole and the protruding element of the corresponding stud of the second storage half-module.
L'invention a aussi pour objet un assemblage de stockage pour bassin de rétention qui comprend :
- un module de stockage tel que brièvement exposé ci-dessus,
- une pluralité de plots supplémentaires montés sur la deuxième grande face opposée de la plaque du premier demi-module de stockage,
- un troisième demi-module de stockage tel que brièvement exposé ci-dessus qui est monté tête bèche et assemblé avec les plots supplémentaires du premier demi-module de stockage par coopération des plots en correspondance et, plus particulièrement, des éléments saillants et des trous traversants des plots en correspondance.
- a storage module as briefly discussed above,
- a plurality of additional pads mounted on the second large opposite face of the plate of the first storage half-module,
- a third storage half-module as briefly described above which is mounted bêche head and assembled with the additional pads of the first storage half-module by cooperation of the corresponding pads and, more particularly, the projecting elements and through holes matching blocks.
Cet agencement ou empilage de demi-modules est moins haut, moins encombrant, moins lourd et donc moins pénible à assembler que dans l'art antérieur (demi-modules et modules conventionnels) en raison de l'utilisation des deux grandes faces opposées de la plaque du premier demi-module.This arrangement or stack of half-modules is less high, less bulky, lighter and therefore less painful to assemble than in the prior art (half-modules and conventional modules) due to the use of two large opposite faces of the plate of the first half-module.

Un demi-module de stockage pour bassin de rétention selon un mode de réalisation de l'invention comprend, d'une part, une plaque 10 en forme de grille (
La plaque 10 est munie, dans son épaisseur, d'une pluralité d'ouvertures traversantes principales, par exemple quatre référencées 12a-d (ayant par exemple chacune une forme générale rectangulaire), et d'une multitude d'ouvertures traversantes secondaires 14. Les ouvertures principales 12a-d ont chacune une section de passage très nettement supérieure à celle des ouvertures secondaires (au moins dans un rapport 10). Les ouvertures principales 12a-d sont dans cet exemple agencées aux quatre coins du rectangle formé par la plaque en laissant dégagé un couloir central 16, tandis que les ouvertures secondaires 14 sont principalement disposées entre les ouvertures principales, dans le couloir central et entre deux ouvertures principales adjacentes 12a-b et 12c-d.The

Les moyens femelles 46b sont au nombre de quatre par grand côté et sont destinés à coopérer avec les moyens 20c de la plaque (
Les moyens 46b présentent une rampe 46b1 sur leur surface extérieure qui coopère par glissement sur une rampe complémentaire 20c1 du moyen complémentaire 20c qui est ici une lamelle élastique. La lamelle élastique 20c est conformée pour comprendre, après la rampe, un retour 20c2 en direction de la paroi intérieure 18a2 de la rigole 18a, conférant ainsi à la partie supérieure du moyen 20c un profil triangulaire. La rampe 20c1 s'efface lors du glissement dessus de la rampe 46b1 et revient dans sa position initiale après franchissement du bord inférieur de la rampe par la rampe 46b1. On bloque ainsi le bord supérieur libre 46b2 par engagement avec le retour 20c2 qui forme un élément de retenue axiale et empêche tout retrait axial (verrouillage des deux moyens d'encliquetage complémentaires l'un par rapport à l'autre).The means 46b have a ramp 46b1 on their outer surface which cooperates by sliding on a complementary ramp 20c1 of the
Seuls deux moyens 46b sont utilisés sur chaque grand côté pour coopérer avec deux moyens complémentaires respectifs 20c comme illustré sur la

Les plaques et les plots étant fabriqués séparément, des matériaux différents peuvent être utilisés de manière à s'adapter aux types d'efforts mécaniques auxquels sont soumis les plaques (efforts latéraux) et les plots (efforts axiaux ou verticaux) et donc afin d'optimiser leurs caractéristiques mécaniques. Les plaques et les plots sont par exemple réalisés par moulage par injection avec un moule pour la plaque 10 et un pour le plot 30. Chaque plot portant les deux types d'organes d'accrochage avec les autres plots, il n'existe qu'un type de plot, ce qui facilite la gestion des références en stock. Les plots 30 sont ainsi plus volumineux que dans l'art antérieur (chaque plot a par exemple une section à la base qui est de 200x400mm au lieu de d'environ 200x200mm dans l'art antérieur), ce qui réduit le nombre d'opérations de montage de plots sur une plaque.The plates and the pads being manufactured separately, different materials can be used to adapt to the types of mechanical forces to which the plates are subjected (lateral forces) and the studs (axial or vertical forces) and therefore in order to optimize their mechanical characteristics. The plates and the pads are for example made by injection molding with a mold for the

Grâce à leur indépendance (caractère séparable) et à leur forme empilable les plaques, d'une part, et les plots d'autre part, peuvent être empilés séparément pour optimiser le transport et le stockage. La manutention des éléments empilés se trouve également facilitée en raison d'un poids moins élevé que dans l'art antérieur (plaque et plots indissociables). Alternativement, le demi-module peut être transporté déjà assemblé ou partiellement assemblé.Thanks to their independence (separable character) and their stackable shape, the plates, on the one hand, and the pads on the other hand, can be stacked separately to optimize the transport and the storage. The handling of the stacked elements is also facilitated because of a lower weight than in the prior art (plate and pads indissociable). Alternatively, the half-module can be transported already assembled or partially assembled.
