Abstract

The device consists of an assembly of two modules (1,2) made of sheet metal. Each module comprises a series of flat elements which form projections (4) and a second series of square elements (6) fixed to the projections. The square elements comprise a first flat part (7) in the same plane as the projections and a second raised flat part (8) which forms a square with the first part. The flat elements are in the same plane as the raised parts and form connections in the form of side frames (9) between the raised parts. The assembly is obtained by installing the two modules so that the raised parts of the second series of elements and the elements forming the side frames are opposite on the two sides of a median plane (5) and the projections of each module extend either side the median plane. An independent claim is included for a module to be sued in the device.

Description

Objet de l'inventionSubject of the invention

La présente invention se rapporte au secteur de la construction, en particulier celui des dalles pour sols industriels et concerne plus particulièrement un dispositif qui sert à équiper des joints de dilatation entre des dalles adjacentes.The present invention relates to the sector of construction, in particular that of slabs for industrial floors and relates more particularly to a device which is used to equip expansion joints between adjacent slabs.

Dans la présente description, le mot 'joint' sert seulement à désigner la zone ou espace qui se trouve entre deux dalles adjacentes, alors que dans le domaine de la construction, ce terme est généralement utilisé pour dénommer en soi le dispositif qui équipe une telle zone.In the present description, the word 'joint' only used to designate the area or space that is between two adjacent slabs, while in the area of construction, this term is generally used for in itself name the device which equips such a zone.

Etat de la techniqueState of the art

Les dispositifs pour équiper des joints de dilatation sont connus dans le domaine des constructions en béton. L'effet souhaité par ce genre de dispositif est de former une connexion entre dalles adjacentes, tout en permettant un mouvement limité d'une dalle par rapport à l'autre dans le plan des dalles, ledit mouvement étant essentiellement dû initialement au retrait de béton lors de la prise et ensuite à la dilatation et rétraction thermiques. Les dispositifs doivent effectuer le transfert de charges entre dalles adjacentes, et maintenir la planéité de l'ensemble des dalles, tout en évitant des ruptures et les détériorations au niveau des arêtes des dalles.Devices for equipping seals with dilation are known in the field of constructions in concrete. The effect desired by this kind of device is to form a connection between adjacent slabs, while allowing limited movement of a slab relative to the other in the plane of the slabs, said movement being primarily due to the shrinkage of concrete during taking and then dilation and retraction thermal. Devices must perform the transfer loads between adjacent slabs, and maintain the flatness of all the slabs, while avoiding ruptures and deterioration at the edges of the slabs.

Le dispositif doit être conçu pour permettre une mise en place rapide et facile lors de la coulée des dalles de béton. Il doit également assurer une résistance mécanique suffisante des arêtes des dalles aux sollicitations de roulage et autres.The device must be designed to allow quick and easy installation when pouring concrete slabs. It must also provide resistance sufficient mechanics of the edges of the slabs taxiing and other stresses.

Une première solution connue dans l'état de la technique utilise des goujons coulissants qui traversent le joint en pénétrant dans le béton des deux côtés, et qui peuvent être munis de renforts d'armatures. Ce sont des systèmes plutôt complexes qu'il est difficile de poser et de maintenir en place lors de la coulée des dalles. En particulier, il existe une difficulté de maintenir les goujons parallèles les uns aux autres pendant l'installation sur le chantier.A first solution known in the state of the technique uses sliding studs that pass through the joint by penetrating the concrete on both sides, and which can be fitted with reinforcements. Those are rather complex systems that are difficult to lay down and to hold in place when pouring the slabs. In in particular, there is a difficulty in maintaining studs parallel to each other for installation on site.

Un autre dispositif utilise des plaques de transfert de charges, qui sont posées en-dessous du joint, de manière à s'étendre d'un bord dudit joint à l'autre, et qui sont munies d'éléments d'ancrage. Désavantageusement, il est difficile d'aligner des plaques individuelles le long d'un joint rectiligne. En plus, ce genre de dispositif ne prévoit aucun renforcement de la partie supérieure du joint, nommée 'lèvres du joint' dans le langage technique.Another device uses plates of load transfer, which are placed below the joint, so as to extend from one edge of said joint to the other, and which are fitted with anchoring elements. disadvantageously, it's difficult to align individual plates the along a straight joint. In addition, this kind of device does not provide for any reinforcement of the upper part of the joint, called 'joint lips' in technical language.

Description détaillée de l'inventionDetailed description of the invention

La figure 1 montre une partie d'un dispositif selon l'invention. Comme il est indiqué par les lignes pointillées, un dispositif complet s'étend de manière répétitive des parties constituantes sur une longueur supérieure, plus particulièrement la longueur du joint complet qui est prévu. Le dispositif est constitué de deux modules similaires (repères 1 et 2) qui sont construits à partir de deux tôles en métal, de préférence en acier. Les tôles sont coupées selon un schéma prédéterminé, puis pliées selon une ligne 3, de façon à former des parties plates engrenantes 4 qui passent en-dessous du plan médian 5, d'un côté du joint à l'autre. Pour la pose sur le chantier, le plan médian 5 est prévu pour coïncider avec celui du joint entre les dalles. Chaque module 1 ou 2, issu d'une tôle découpée et conformée comporte une série de ces parties plates 4, qu'on appellera aussi 'les saillies' 4 de chaque module. Entre les saillies de chacun des deux modules 1 ou 2, une série d'éléments 6 en forme d'équerre est présente, lesdits éléments 6 étant solidaires avec les saillies 4 et comprenant une partie 7 dans le même plan que les saillies, et une partie relevée 8. Ces parties relevées 8 sont rattachées entre elles à leurs extrémités par un premier longeron 9 vertical lorsque posé. Les longerons 9 ont le but de renforcer la partie supérieure ou arête des dalles, c'est à dire ce qui va constituer les lèvres du joint. Les parties relevées 8 et les longerons 9 respectivement des deux modules 1 et 2 sont dos à dos, et de préférence solidarisée par des moyens de fixation provisoires, tels que des boulons 10, des clips ou autres moyens adéquats.Figure 1 shows part of a device according to the invention. As indicated by the lines dotted, a complete device extends so repetitive of the constituent parts over a length greater, especially the length of the joint full that is expected. The device consists of two similar modules (marks 1 and 2) which are built at from two metal sheets, preferably steel. The sheets are cut according to a predetermined pattern, then folded along a line 3, so as to form parts meshing plates 4 which pass below the median plane 5, from one side of the joint to the other. For laying on the site, the median plane 5 is planned to coincide with that of the joint between the slabs. Each module 1 or 2, from of a cut and shaped sheet includes a series of these flat parts 4, which will also be called 'projections' 4 of each module. Between the projections of each of the two modules 1 or 2, a series of 6 square elements is present, said elements 6 being integral with the projections 4 and comprising a part 7 in the same plane as the projections, and a raised part 8. These raised parts 8 are joined together at their ends by a first vertical beam 9 when installed. The stringers 9 are intended to strengthen the upper part or edge of slabs, that is to say what will constitute the lips of the seal. The raised parts 8 and the side members 9 respectively of the two modules 1 and 2 are back to back, and preferably secured by fixing means temporary, such as 10 bolts, clips or the like adequate means.

De préférence, une feuille de séparation 12 est incluse entre les modules 1 et 2, de façon à séparer le béton des deux côtés du joint. La feuille 12 de séparation peut être réalisée en métal ou en un matériau synthétique, de préférence compressible tel que la mousse de polystyrène.Preferably, a separation sheet 12 is included between modules 1 and 2, so as to separate the concrete on both sides of the joint. The separation sheet 12 can be made of metal or a synthetic material, preferably compressible such as foam polystyrene.

Des éléments d'ancrage, ayant des formes variables, par exemple des goujons 11 sont de préférence attachés au longeron 9 de chacun des deux modules 1 et 2. De tels éléments d'ancrage ne sont pas nécessairement perpendiculaires à la partie 8 et d'autres angles peuvent être choisis.Anchoring elements, having shapes variables, for example studs 11 are preferably attached to the spar 9 of each of the two modules 1 and 2. Such anchors are not necessarily perpendicular to part 8 and other angles can to be chosen.

Dans la forme d'exécution montrée aux figures 1 et 2, chacune des saillies 4 de chaque module est connectée à la partie 7 de la saillie voisine, par un deuxième longeron plat 13 horizontal, lorsque posé. On notera que ce longeron 13 ne constitue pas un élément essentiel. Il est purement optionnel dans le cadre de l'invention bien qu'il contribue à la rigidité du montage du fait qu'il se trouve sous la dalle ou qu'il est noyé dans celle-ci.In the embodiment shown in the figures 1 and 2, each of the projections 4 of each module is connected to part 7 of the neighboring projection, by a second horizontal flat beam 13, when installed. We note that this spar 13 does not constitute an element essential. It is purely optional in the context of the invention although it contributes to the rigidity of the assembly because it is under the slab or drowned in this one.

De préférence, la longueur des saillies 4 est telle qu'il n'y a pas de contact direct entre l'extrémité 20 d'une saillie qui appartient à un module 1 ou 2, et le longeron plat 13 de l'autre module. De même, la distance 21 entre deux saillies adjacentes des deux modules 1 et 2, telle que la distance 22 entre une saillie 4 d'un module 1 ou 2 et une partie plate 7 de l'autre module, est telle qu'il y a une absence de contact direct entre les éléments séparés par lesdites distances. En général, on peut dire qu'une saillie 4 appartenant à un module 1 ou 2 n'a pas de contact physique avec aucune partie de l'autre module, dans l'assemblage de l'invention. Dans chaque forme d'exécution de l'invention, les saillies 4 du dispositif forment un schéma d'engrenage, avec des parties en équerre 6 pouvant se trouver entre deux saillies consécutives.Preferably, the length of the projections 4 is such that there is no direct contact between the end 20 of a projection which belongs to a module 1 or 2, and the flat spar 13 of the other module. Similarly, the distance 21 between two adjacent projections of the two modules 1 and 2, such that the distance 22 between a projection 4 of a module 1 or 2 and a flat part 7 of the other module, is such that there is an absence of direct contact between the elements separated by said distances. In general, we can say that a projection 4 belonging to a module 1 or 2 has no physical contact with any part of the other module, in the assembly of the invention. In each form of execution of the invention, the projections 4 of the device form a gear diagram, with square parts 6 which can be between two consecutive projections.

Les éléments caractéristiques de l'invention sont les suivants : il s'agit d'un dispositif continu, pouvant être installé sur une longueur importante du joint, facilitant ainsi la pose et l'alignement. Ledit dispositif est généralement assemblé avant d'être mis sur place sur le chantier. Ledit dispositif, tout en étant continu, comprend des parties 4 qui se trouvent en-dessous ou noyées dans des dalles en béton en traversant le joint. Les saillies 4 se trouvent de part et d'autre dudit joint, assurant ainsi le transfert de charges souhaité. Le dispositif comprend en plus des parties 6 en équerre, rattachées entre elles par des longerons 9 qui se trouvent aux deux côtés des parties supérieures du joint, et qui forment ainsi un renforcement des lèvres du joint et solidarisent l'ensemble.The characteristic elements of the invention are as follows: it is a continuous device, can be installed over a significant length of the joint, thus facilitating installation and alignment. Said device is generally assembled before being placed on site construction site. Said device, while being continuous, comprises parts 4 which are below or embedded in concrete slabs crossing the joint. The projections 4 are found on either side of said joint, thus ensuring the charge transfer desired. The device includes plus parts 6 at right angles, joined together by longitudinal members 9 which are on both sides of the parts of the joint, and which thus form a reinforcement lips of the joint and secure the assembly.

Les figures 3a à 3d montrent un exemple d'un schéma de découpage, pliage et assemblage d'une tôle 30, pour former un module 1 qui fera partie du dispositif de l'invention, montré aux figures 1 et 2. Après le découpage, la tôle 30 est pliée en équerre selon la ligne 3, de telle façon que les éléments 4 restent dans le plan initial. La figure 3c montre le résultat, vu de haut. On reconnaít les saillies 4, les parties en équerre 6, les premiers longerons 9 dans le plan en équerre, et les deuxièmes longerons 13 dans le plan des saillies. La figure 3d montre l'assemblage de deux modules 1 et 2 conformés et découpés du même type pour former un dispositif selon l'invention.Figures 3a to 3d show an example of a diagram for cutting, folding and assembling a sheet 30, to form a module 1 which will be part of the the invention, shown in Figures 1 and 2. After cutting, the sheet 30 is folded at right angles along line 3, such that so that the elements 4 remain in the initial plan. The Figure 3c shows the result, seen from above. We recognize the projections 4, the square parts 6, the first longitudinal members 9 in the square plan, and the second longitudinal members 13 in the plane of the projections. 3d figure shows the assembly of two modules 1 and 2 shaped and cut of the same type to form a device according to the invention.

Le détail à la figure 4a démontre clairement ce qu'on comprend dans le contexte de cette description comme les éléments 4, 6, 7, 8, 9 et 13 de la forme d'exécution montrée aux figures 1 à 3. La figure 4b montre une forme qui est légèrement différente, et dans laquelle les longerons 9 consistent d'une partie 9a qui s'étend essentiellement sur la hauteur complète du dispositif, et une partie 9b qui s'étend sur une hauteur réduite. Dans l'assemblage, les parties 9a d'un des deux modules vont se trouver en face des parties 9b de l'autre module. Les parties 9a des deux modules vont donc essentiellement bloquer le passage du béton d'un côté du joint vers l'autre. Dans cette forme du dispositif de l'invention, on peut alors supprimer la feuille de séparation 12. Dans certains cas, il peut quand-même être utile d'ajouter une feuille de séparation, par exemple une feuille en polystyrène, pouvant compenser une dilatation importante des dalles.The detail in Figure 4a clearly demonstrates what we understand in the context of this description like elements 4, 6, 7, 8, 9 and 13 of the form shown in Figures 1 to 3. Figure 4b shows a form which is slightly different, and in which the side members 9 consist of a part 9a which extends essentially on the full height of the device, and a part 9b which extends over a reduced height. In assembly, parts 9a of one of the two modules will find opposite parts 9b of the other module. The parts 9a of the two modules therefore basically go block the passage of concrete from one side of the joint to the other. In this form of the device of the invention, it is can then delete the separation sheet 12. In in some cases it may still be useful to add a separation sheet, for example a sheet of polystyrene, which can compensate for significant expansion slabs.

Aux figures 5a à 5d, on voit une forme d'exécution qui n'est pas pourvue des longerons 13 dans le plan des saillies 4. Cette forme d'exécution est équivalente à la forme précédente dans son principe, bien que moins rigide.In Figures 5a to 5d, we see a shape which is not provided with side members 13 in the projection plan 4. This embodiment is equivalent to the previous form in principle, well that less rigid.

Aux figures 6a à 6d, on voit une forme d'exécution préférée d'un dispositif complet de l'invention. Chacun des modules 1 ou 2 est représenté comme comprenant quatre saillies 4. Les modules 1 et 2 comprennent des extensions 31 et 32 à leurs extrémités, en forme de parties verticales qui facilitent le montage d'un deuxième dispositif qui forme un angle avec le premier.In Figures 6a to 6d, we see a shape preferred execution of a complete device the invention. Each of modules 1 or 2 is represented as comprising four projections 4. Modules 1 and 2 include extensions 31 and 32 at their ends, in form of vertical parts which facilitate the mounting of a second device which forms an angle with the first.

Aux figures 7a à 7d, on voit encore une autre forme d'exécution, plus particulièrement un schéma de découpage, pliage et assemblage spécifique selon l'invention. Les lignes pointillées représentent les limites des parties portant les repères numériques indiquées. Dans cette forme du dispositif assemblé de l'invention, chaque saillie 4 d'un des deux modules 1, 2 se trouve entre deux parties 7 de l'équerre de l'autre module. Ce dispositif est équivalent aux dispositifs déjà décrits. Il comprend deux types de longerons 9 : les longerons 9a qui s'étendent essentiellement sur la hauteur du dispositif complet, et les longerons 9b qui s'étendent sur une hauteur réduite.In Figures 7a to 7d, we see yet another form of execution, more particularly a diagram of cutting, folding and specific assembly according to the invention. The dotted lines represent the limits of the parts bearing the numerical marks indicated. In this form of the assembled device of the invention, each projection 4 of one of the two modules 1, 2 is located between two parts 7 of the square of the other module. This device is equivalent to the devices already described. It includes two types of spars 9: the spars 9a which extend essentially over the height of the device complete, and the side members 9b which extend over a height scaled down.

Dans l'assemblage, les parties 9a d'un module vont se trouver en face des parties 9b de l'autre module. Comme dans la forme montrée à la figure 4b, on peut donc supprimer la feuille de séparation 12, sauf dans des cas particuliers.In the assembly, the parts 9a of a module will be in front of parts 9b of the other module.
