Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

L'invention concerne de manière générale le domaine du stockage et du rangement de tous types de charges, notamment sur un platelage.The invention relates generally to the field of storage and arrangement of all types of loads, in particular on a deck.

Elle concerne plus particulièrement un platelage mettant en œuvre un treillis de fils métalliques soudés entre eux à leurs intersections.It relates more particularly to a decking using a mesh of metal wires welded together at their intersections.

ETAT ANTERIEUR DE LA TECHNIQUEPRIOR STATE OF THE ART

Pour le stockage de charges, notamment en entrepôt, les platelages métalliques sont d'un usage largement répandu. De tels platelages se composent majoritairement d'un treillis de fils métalliques, soudés entre eux au niveau de leurs intersections. Des platelages en bois sont également utilisés.For the storage of loads, particularly in warehouses, metal decks are widely used. Such decks consist mainly of a mesh of metal wires, welded together at their intersections. Wooden decks are also used.

Dans le but de renforcer ces treillis, classiquement sollicités en flexion sous le poids de la charge qu'ils reçoivent et suivant la direction longitudinale, les solutions de stockage existantes utilisent un panneau grillagé sur lequel sont soudés des renforts en tôle. Cependant, ces renforts constituent des zones de rétentions de saletés et d'eau.With the aim of reinforcing these trellises, conventionally stressed in bending under the weight of the load which they receive and in the longitudinal direction, the existing storage solutions use a grid panel onto which sheet reinforcements are welded. However, these reinforcements constitute areas of retention of dirt and water.

De même, afin de palier un manque de rigidité et d'empêcher que les soudures ne se rompent, il a été proposé de réaliser des platelages pour lesquels le treillis est haubané (voir par exemple le document FR 2 991 971 ). Dans cette configuration, le hauban est soudé à des fils longitudinaux constitutifs du treillis. Au moins une entretoise est interposée entre le hauban et le treillis. Malgré cette modification, le maintien en position de l'entretoise par le hauban peut être fragilisé en raison d'une sollicitation répétée de la structure. En outre, la réalisation de la soudure des haubans est complexe à mettre en œuvre.Likewise, in order to overcome a lack of rigidity and to prevent the welds from breaking, it has been proposed to produce decks for which the trellis is guyed (see for example the document FR 2 991 971 ). In this configuration, the stay cable is welded to the longitudinal wires constituting the mesh. At least one spacer is interposed between the stay and the trellis. Despite this modification, the stay in position of the spacer by the stay may be weakened due to repeated stress on the structure. In addition, carrying out the welding of the stay cables is complex to implement.

Corollairement, on a décrit dans le document AT 006326 un platelage constitué de deux treillis métalliques superposés, susceptibles d'être assemblés entre eux par soudure. Si ce platelage permet d'optimiser la résistance à la flexion, la rigidité de l'ensemble demeure néanmoins insuffisante pour un certain nombre d'applications.
L'objectif de la présente invention vise à remédier aux inconvénients précités.As a corollary, we have described in the document AT 006326 a deck consisting of two superimposed metal trellises, capable of being assembled together by welding. If this deck optimizes the bending resistance, the rigidity of the assembly remains nevertheless insufficient for a certain number of applications.
The objective of the present invention is to remedy the aforementioned drawbacks.

EXPOSE DE L'INVENTIONDISCLOSURE OF THE INVENTION

L'invention propose en premier lieu un platelage comportant deux panneaux grillagés, c'est-à-dire du type constitué de treillis de fils métalliques, positionnés l'un sur l'autre et associés l'un à l'autre par soudure.The invention firstly proposes a decking comprising two mesh panels, that is to say of the type consisting of a mesh of metal wires, positioned one on top of the other and associated with one another by welding.

Selon l'invention, le plateau ou panneau supérieur, destiné à recevoir la charge, est renforcé au moyen d'un second panneau grillagé, ce dernier présentant par construction des plis orientés selon l'une des directions des fils métalliques constitutifs dudit second panneau, et formant saillie, typiquement en forme de « V » par rapport au plan défini par ledit second panneau.According to the invention, the top plate or panel, intended to receive the load, is reinforced by means of a second mesh panel, the latter having by construction folds oriented in one of the directions of the metal wires constituting said second panel, and protruding, typically in the shape of a "V" with respect to the plane defined by said second panel.

Les deux panneaux sont soudés entre eux de manière à aligner l'ensemble des fils horizontaux et verticaux. Plus spécifiquement, les fils de maillage du panneau supérieur sont soudés au-dessus des fils d'appui du panneau inférieur. On optimise ainsi la rigidité aux fils d'extrémité du plateau supérieur, rigidité tout particulièrement recherchée lorsque ledit platelage est positionné sur un rack.The two panels are welded together so as to align all the horizontal and vertical wires. More specifically, the top panel mesh wires are welded above the bottom panel backer wires. The rigidity of the end wires of the upper plate is thus optimized, a rigidity that is most particularly sought after when said decking is positioned on a rack.

Les deux panneaux forment alors un platelage tout fil, c'est-à-dire exempt de tout élément de renfort additionnel.The two panels then form an all-grain deck, that is to say free of any additional reinforcing element.

Les plis définis par le second panneau confèrent à l'ensemble un effet « poutre », apte à optimiser la résistance mécanique du platelage, et à diminuer voire éviter tout phénomène de flèche susceptible de résulter du stockage de charge sur ledit platelage.The folds defined by the second panel give the assembly a “beam” effect, capable of optimizing the mechanical strength of the decking, and of reducing or even avoiding any sagging phenomenon likely to result from the storage of load on said decking.

L'invention peut être configurée de manière à s'adapter à l'utilisation de charges encore plus lourdes. Ainsi, le diamètre des fils d'acier constitutifs des panneaux peut varier en fonction de la charge à supporter, de même que le nombre et le positionnement des plis de renfort en « V ».The invention can be configured to accommodate the use of even heavier loads. Thus, the diameter of the steel wires constituting the panels can vary depending on the load to be supported, as can the number and positioning of the reinforcing “V” folds.

En raison de ces modifications, ce platelage tout fil permet notamment:

  • le passage de la lumière au travers des panneaux, facilitant l'identification des produits stockés ;
  • l'écoulement de l'eau ;
  • d'éviter la rétention de saletés ;
  • d'améliorer l'esthétique.
Due to these modifications, this all-wire decking allows in particular:
  • the passage of light through the panels, facilitating the identification of stored products;
  • water flow;
  • avoid the retention of dirt;
  • improve aesthetics.

Avantageusement, dans l'objectif de résister encore davantage à des charges importantes, le platelage de l'invention peut être renforcé mécaniquement par l'ajout d'éléments entre les deux panneaux grillagés. Plus précisément, ces éléments de renfort additionnels sont positionnés au niveau des plis en « V », et se composent soit d'un fil ou fer-rond, d'un fer plat ou d'une cornière orientable.Advantageously, with the aim of resisting even greater loads, the decking of the invention can be mechanically reinforced by adding elements between the two mesh panels. More precisely, these additional reinforcing elements are positioned at the level of the "V" folds, and consist of either a wire or round iron, a flat iron or an adjustable angle iron.

L'invention vise en second lieu un dispositif de stockage et de rangement mettant en œuvre un ou plusieurs platelages du type précité.Secondly, the invention relates to a storage and arrangement device implementing one or more decks of the aforementioned type.

DESCRIPTION DETAILLEE DE L'INVENTIONDETAILED DESCRIPTION OF THE INVENTION

Fondamentalement, le platelage tout fil de l'invention est constitué de deux panneaux grillagés associés l'un à l'autre par soudage.Basically, the all-wire decking of the invention consists of two mesh panels which are joined together by welding.

On a représenté sur la figure 1 un dispositif de stockage et de rangement (1) intégrant de tels platelages (5). Ces platelages (5) présentés ici dans leur configuration d'utilisation, définissent une face supérieure pour l'accueil d'une charge, notamment des produits de toute nature (non représentée).One represented on the figure 1 a storage and arrangement device (1) incorporating such decks (5). These decks (5) shown here in their configuration of use, define an upper face for receiving a load, in particular products of any kind (not shown).

Sur la figure 1, le platelage (5) repose sur deux lisses horizontales (4), elles-mêmes vissées et de manière générale, solidarisées sur des échelles (2). Ces échelles (2) s'étendent verticalement depuis le sol et sont maintenues entre elles à l'aide d'entretoises (3).On the figure 1 , the decking (5) rests on two horizontal rails (4), themselves screwed and generally secured on ladders (2). These ladders (2) extend vertically from the ground and are held together by means of spacers (3).

Comme le montrent les figures 2 et 3, le platelage (5) est constitué de deux panneaux distincts superposés : un panneau supérieur (6) et un panneau inférieur (7).As the figures 2 and 3 , the decking (5) consists of two separate superimposed panels: an upper panel (6) and a lower panel (7).

Le panneau supérieur (6), servant de plateau de réception des charges et produits, est constitué de mailles. C'est-à-dire qu'il se compose de fils d'appui (8) et de fils de maillage (9) soudés entre eux à leurs intersections, comme schématisé sur les figures 3 et 5.The upper panel (6), serving as a tray for receiving loads and products, is made of meshes. That is to say, it consists of support wires (8) and mesh wires (9) welded together at their intersections, as shown schematically on the figures 3 and 5 .

Les fils d'appui (8) et les fils de maillage (9) sont espacés d'une distance constante pour former un maillage rectangulaire régulier. Typiquement, ces fils présentent un diamètre compris entre 3 et 10 millimètres.The backing wires (8) and the mesh wires (9) are spaced a constant distance apart to form a regular rectangular mesh. Typically, these wires have a diameter of between 3 and 10 millimeters.

De cette manière, le panneau supérieur (6) assure une fonction d'appui pour la charge qu'il est destiné à recevoir, avec une déformation homogène de la structure et une répartition des pressions optimum.In this way, the upper panel (6) provides a support function for the load that it is intended to receive, with a homogeneous deformation of the structure and an optimum pressure distribution.

Selon une caractéristique de l'invention, un panneau grillagé inférieur (7) supplémentaire est assemblé au panneau supérieur (6).According to one characteristic of the invention, an additional lower mesh panel (7) is assembled to the upper panel (6).

Le panneau inférieur (7) se compose de fils métalliques d'appui (10) et de fils de maillage (11) et forme un renfort pour le platelage (5).The lower panel (7) consists of supporting metal wires (10) and mesh wires (11) and forms a reinforcement for the decking (5).

En effet, comme le montre la figure 3, le panneau inférieur (7) comporte un certain de nombre de plis (12) en forme de « V », parallèles les uns par rapport aux autres, et résultant de la déformation des fils de maillage (11) selon l'une des deux dimensions.Indeed, as shown in figure 3 , the lower panel (7) comprises a certain number of folds (12) in the shape of a "V", parallel to each other, and resulting from the deformation of the mesh threads (11) according to one of the two dimensions.

Avantageusement, les plis (12) du panneau inférieur (7) sont agencés du côté de la face inférieure du platelage (5).Advantageously, the folds (12) of the lower panel (7) are arranged on the side of the lower face of the decking (5).

Ainsi, grâce à l'invention, le panneau inférieur (7) rigidifie le platelage (5) par effet poutre.Thus, thanks to the invention, the lower panel (7) stiffens the decking (5) by the beam effect.

En outre, des fils de renfort (13) sont soudés au sommet des plis (12) selon l'axe des fil d'appui (10) du panneau inférieur (7). Ces fils de renfort (13) ont, dans cet exemple, un diamètre égal au diamètre des fils d'appui (10) et de maillage (11). De cette manière, on obtient un platelage offrant une meilleure résistance à la charge.In addition, reinforcing threads (13) are welded to the top of the plies (12) along the axis of the support threads (10) of the lower panel (7). These reinforcing threads (13) have, in this example, a diameter equal to the diameter of the support threads (10) and of the mesh (11). In this way, a decking is obtained with better resistance to the load.

L'assemblage des panneaux grillagés (6) et (7) est réalisé par soudure par résistance, sans apport, avec écrasement des deux corps pour une pénétration et fusion des deux matières, haute fréquence, basse ou moyen fréquence, aussi dite soudure HF. Ce procédé permet notamment la liaison des quatre fils (8, 9, 10 et 11) (voir figure 5).The mesh panels (6) and (7) are assembled by resistance welding, without input, with crushing of the two bodies for penetration and fusion of the two materials, high frequency, low or medium frequency, also called HF welding. This process allows in particular the connection of the four wires (8, 9, 10 and 11) (see figure 5 ).

Plus particulièrement, comme le montre la figure 4, les fils de maillage (9) du panneau supérieur (6) sont soudés au-dessus des fils d'appui (10) du panneau inférieur (7). L'empilage des fils (9, 10 et 11) confère alors une meilleure rigidité aux fils d'extrémité (18) (en fait constitués par le prolongement des fils (8)), qui sont en appui sur les lisses (4) du rack ou dispositif de stockage et de rangement (1), comme on l'a schématiquement décrit sur la figure 6. Ce faisant, on augmente encore la rigidité du platelage (5).More particularly, as shown in figure 4 , the mesh wires (9) of the upper panel (6) are welded above the support wires (10) of the lower panel (7). Stacking the wires (9, 10 and 11) then gives better rigidity to the end wires (18) (in fact constituted by the extension of the wires (8)), which are supported on the heddles (4) rack or storage and arrangement device (1), as has been schematically described on figure 6 . In doing so, the rigidity of the decking (5) is further increased.

Selon encore une caractéristique avantageuse de l'invention, les fils de renfort (13) évoqués précédemment peuvent être remplacés par des renforts complémentaires. Ces renforts viennent se loger dans les plis (12) qui ont des hauteurs adaptées.According to yet another advantageous characteristic of the invention, the reinforcing threads (13) mentioned above can be replaced by additional reinforcements. These reinforcements are housed in the folds (12) which have suitable heights.

Dans une première configuration, les renforts sont de type fer-rond (14) comme représentés sur les figures 7 et 8.In a first configuration, the reinforcements are of the round iron type (14) as shown in the figures 7 and 8 .

Ces fers-ronds (14) longitudinaux sont soudés au sommet des plis (12) selon l'axe des fils d'appui (10) du panneau inférieur (7).These longitudinal rods (14) are welded to the top of the folds (12) along the axis of the support wires (10) of the lower panel (7).

Le diamètre de ces fers-ronds (14) est supérieur à la profondeur des plis (12) empêchant tout contact entre le panneau supérieur (6) et le panneau inférieur (7) (voir figure 8).The diameter of these rods (14) is greater than the depth of the folds (12) preventing any contact between the upper panel (6) and the lower panel (7) (see figure 8 ).

Dans une deuxième configuration, les renforts sont du type fer-plat (15) comme représentés sur la figure 9.In a second configuration, the reinforcements are of the flat iron type (15) as shown on figure 9 .

Ces fers-plats (15) longitudinaux sont orientés verticalement et soudés au sommet des plis (12) selon l'axe des fils d'appui (10) du panneau inférieur (7).These longitudinal flat bars (15) are oriented vertically and welded to the top of the folds (12) along the axis of the support wires (10) of the lower panel (7).

La hauteur de ces fers-plats (15) est inférieure à la profondeur des plis (12) empêchant tout contact entre le panneau supérieur (6) et le panneau inférieur (7).The height of these flat bars (15) is less than the depth of the folds (12) preventing any contact between the upper panel (6) and the lower panel (7).

Dans une dernière configuration, les renforts sont du type cornière (16) comme représentés sur les figures 10 à 13.In a last configuration, the reinforcements are of the angle type (16) as shown on the figures 10 to 13 .

Ces cornières longitudinales (16) peuvent être orientées suivant deux directions. Lorsqu'orientées vers le bas, les cornières (16) présentent une section en forme de « V » renversé, comme représenté sur les figures 10 et 11. A l'inverse, lorsqu'orientées vers le haut, les cornières (16) présentent une section en forme de « V », comme représenté sur les figures 12 et 13.These longitudinal angles (16) can be oriented in two directions. When facing down, the angles (16) have an inverted "V" shaped section, as shown in the illustrations. figures 10 and 11 . Conversely, when facing upwards, the angles (16) have a "V" shaped section, as shown in the figures. figures 12 and 13 .

Pour le choix d'une orientation vers le bas, la hauteur des ailes des cornières (16), prenant comme plan d'origine le plan défini par les lignes de contact entre ces mêmes cornières (16) et les plis (12), projetée selon l'axe perpendiculaire au plan des panneaux grillagés (6) et (7) est suffisamment grande pour éviter tout contact entre le panneau supérieur (6) et le panneau inférieur (7) (voir figure 11).For the choice of a downward orientation, the height of the wings of the angles (16), taking as the original plane the plane defined by the lines of contact between these same angles (16) and the folds (12), projected along the axis perpendicular to the plane of the mesh panels (6) and (7) is large enough to avoid any contact between the upper panel (6) and the lower panel (7) (see figure 11 ).

Pour le choix d'une orientation vers le haut, la hauteur des ailes des cornières (16), prenant comme origine la ligne de contact entre ces mêmes cornières (16) et le sommet des plis (12), projetée selon l'axe perpendiculaire au plan des panneaux grillagés (6) et (7) est suffisamment grande pour éviter tout contact entre le panneau supérieur (6) et le panneau inférieur (7) (voir figure 12).For the choice of an upward orientation, the height of the wings of the angles (16), taking as origin the line of contact between these same angles (16) and the top of the folds (12), projected along the perpendicular axis in the plane of the mesh panels (6) and (7) is large enough to avoid any contact between the upper panel (6) and the lower panel (7) (see figure 12 ).

Ainsi, ces variantes caractéristiques de l'invention rigidifient davantage le platelage et permettent de résister à des charges supérieures à 500 kg.Thus, these characteristic variants of the invention further stiffen the decking and make it possible to withstand loads greater than 500 kg.

Les éléments de renfort sont soudés par soudure HF ou semi-auto MIG-MAG.The reinforcing elements are welded by HF or semi-automatic MIG-MAG welding.

On conçoit tout l'intérêt du platelage de l'invention, qui en raison de sa structure d'une part, et du mode de solidarisation des panneaux constitutifs du platelage entre eux, permet de supporter des charges importantes.We can imagine the advantage of the decking of the invention, which, by virtue of its structure on the one hand, and of the method of securing the constituent panels of the decking together, makes it possible to withstand significant loads.
