Description

Objet de l'inventionObject of the invention

La présente invention se rapporte au domaine de la construction, et plus particulièrement au domaine des profils destinés à équiper les joints de dilatation entre deux parties de dalle dans les dallages ou dalles de béton sur sol.The present invention relates to the field of construction, and more particularly to the field of profiles intended to equip the expansion joints between two slab portions in slabs or concrete slabs on ground.

Etat de la techniqueState of the art

L'utilisation de dispositifs pourvus de profils métalliques pour protéger les dalles de béton au niveau de la partie supérieure avec goujons ou doguets (ou saillies) pour l'ancrage et/ou avec éléments pour le transfert de charge est connue. Des exemples de ce type de dispositifs sont décrits dans les documents EP-A-1391556 et EP-A-1905898 .The use of devices with metal profiles to protect the concrete slabs at the top with studs or doguets (or protrusions) for anchoring and / or with elements for the transfer of load is known. Examples of this type of devices are described in the documents EP-A-1391556 and EP-A-1905898 .

L'un des problèmes rencontrés est la protection des bords des dalles de béton : pour la réalisation des dalles, il convient en effet, en phase provisoire (avant ou pendant la coulée du béton), de maintenir à niveau les profils de protection. Souvent, une connexion provisoire est prévue au niveau des tôles verticales qui sont attachées en dessous des profils et qui servent de tôles de séparation entre les dalles. Malgré cette connexion, on observe souvent que les profils ne restent pas exactement dans le même plan horizontal lors de la coulée du béton. En phase définitive (après la coulée du béton), l'ouverture du joint peut engendrer des chocs ou à-coups lors du passage de roues de véhicule ou d'engin de manutention, ces chocs réguliers entraînant à plus long terme une détérioration du béton. Ces chocs ou à-coups sont d'autant plus importants que les deux profils ne sont pas ou plus dans le même plan (horizontal).One of the problems encountered is the protection of the edges of the concrete slabs: for the realization of the slabs, it is necessary in fact in the provisional phase (before or during the pouring of the concrete), to keep the protection profiles level. Often, a temporary connection is provided at the level of the vertical sheets which are attached below the profiles and which serve as separating plates between the slabs. Despite this connection, it is often observed that the profiles do not remain exactly in the same horizontal plane during the pouring of the concrete. In final phase (after casting concrete), the opening of the seal can cause shocks or jolts when passing vehicle wheels or handling equipment, these regular shocks resulting in longer term deterioration of the concrete. These shocks or jerks are all the more important that the two profiles are not or more in the same plane (horizontal).

Dans les dispositifs décrits dans le document DE-A-102007020816 et dans le document EP-A-0953682 , les profils sont pourvus d'éléments de transfert de charge qui pourraient maintenir les profils à niveau en phase provisoire. Toutefois, l'inconvénient majeur de ce type de dispositif est que ces éléments de transfert de charge se trouvent nécessairement présents au milieu de l'épaisseur totale de la dalle. Dans ce cas de figure, il est évident que le profil devra présenter soit une hauteur importante, soit une forme complexe, surtout dans le cas où l'épaisseur de la dalle est importante, et donc nécessiter un volume de matière (acier) important, ce qui, bien entendu, est particulièrement désavantageux au niveau économique.In the devices described in the document DE-A-102007020816 and in the document EP-A-0953682 , the profiles are provided with load transfer elements that could keep the profiles level in the interim phase. However, the major disadvantage of this type of device is that these charge transfer elements are necessarily present in the middle of the total thickness of the slab. In this case, it is obvious that the profile must have either a large height or a complex shape, especially in the case where the thickness of the slab is important, and therefore require a volume of material (steel), which, of course, is particularly disadvantageous at the economic level.

Principaux éléments caractéristiques de l'inventionMain characteristic elements of the invention

La présente invention vise avantageusement à surmonter l'inconvénient décrit ci-dessus. L'invention se rapporte à un dispositif tel que décrit dans les revendications.The present invention is advantageously aimed at overcoming the disadvantage described above. The invention relates to a device as described in the claims.

Selon un premier aspect, l'invention se rapporte à un dispositif destiné à équiper un joint de dilatation entre deux dalles de béton adjacentes, le dispositif comprenant deux profils longitudinaux, disposés face à face, de façon à former les bords desdites dalles de béton à couler, caractérisé en ce que le dispositif comprend une pluralité de goujons (ou doguets) d'ancrage, lesdits goujons (ou doguets) étant solidaires avec le dispositif et comprenant une partie plate qui se trouve sous la face inférieure des profils, de façon à maintenir les profils dans le même plan (horizontal). Cette structure permet d'éliminer le problème décrit ci-dessus en maintenant les profils dans un même plan en phase provisoire, donc avant et/ou pendant la coulée du béton.According to a first aspect, the invention relates to a device for equipping an expansion joint between two adjacent concrete slabs, the device comprising two longitudinal profiles, arranged face to face, so as to form the edges of said concrete slabs to pouring, characterized in that the device comprises a plurality of anchoring studs (or doguets), said studs (or doguets) being integral with the device and comprising a flat part which is located under the lower face of the profiles, so as to maintain the profiles in the same (horizontal) plane. This structure eliminates the problem described above by maintaining the profiles in the same plane in the provisional phase, so before and / or during the pouring of the concrete.

Il est à noter que l'invention se limite à des dispositifs dans lesquels lesdites parties plates font parties des goujons (ou doguets) d'ancrage, c'est-à-dire que ce sont les goujons (ou doguets) qui servent à solidariser chaque profil avec la dalle de béton correspondante. L'invention ne couvre donc pas des systèmes dans lesquels les éléments de transfert de charge pourraient jouer le rôle de la mise en place des profils en phase provisoire. Il est également clair que les parties plates des goujons (ou doguets) d'ancrage se positionnent sous la face inférieure des profils.It should be noted that the invention is limited to devices in which said flat parts are part of anchor studs (or doguets), that is to say that it is the studs (or doguets) that serve to secure each profile with the corresponding concrete slab. The invention therefore does not cover systems in which the charge transfer elements could play the role of setting up profiles in the temporary phase. It is also clear that the flat portions of the anchor studs (or doguets) are positioned under the underside of the profiles.

L'invention se distingue donc des systèmes ou dispositifs de l'état de l'art dans lesquels les profils eux-mêmes sont pourvus de parties plates telles que des éléments de transfert de charge, qui pourraient assurer ledit maintien en phase provisoire (soit avant ou pendant la coulée du béton).The invention is thus distinguished from systems or devices of the state of the art in which the profiles themselves are provided with flat parts such as load transfer elements, which could ensure said maintenance in the provisional phase (before or during casting of concrete).

L'avantage du dispositif de l'invention vis-à-vis de systèmes ou dispositifs de l'état de la technique dans lesquels les éléments de transfert de charge permettent de maintenir les profils à niveau est que les profils peuvent être réduits en volume, c'est-à-dire que la masse de métal et en particulier d'acier nécessaire à la réalisation du profil est réduite de façon importante.The advantage of the device of the invention with respect to systems or devices of the state of the art in which the charge transfer elements make it possible to keep the profiles level is that the profiles can be reduced in volume, that is to say that the mass of metal and in particular of steel necessary for producing the profile is reduced significantly.

Dans l'invention, les parties plates qui maintiennent les profils à niveau ne font parties que des goujons (ou doguets) d'ancrage, ce qui permet d'utiliser des profils de faible hauteur, surtout en comparaison avec la hauteur totale de la dalle.In the invention, the flat portions that maintain the level profiles are only anchor dowels (or doguets), which allows the use of low profiles, especially in comparison with the total height of the slab .

La partie plate de chaque goujon (ou doguet) peut être fixée sur la face inférieure d'un profil et déborder de la largeur de ladite face inférieure de façon à supporter l'autre (le second) profil, sans être assujettie (ou solidaire) audit autre (second) profil.The flat part of each stud (or doguet) can be fixed on the lower face of one profile and extend beyond the width of said lower face so as to support the other (the second) profile, without being secured (or secured) audit other (second) profile.

Dans un autre cas, le dispositif comprend des tôles de séparation, respectivement solidaires avec les profils, et les goujons (ou doguets) d'ancrage sont fixés auxdites tôles de séparation.In another case, the device comprises separating plates, respectively integral with the profiles, and anchor studs (or doguets) are fixed to said separating plates.

Selon un autre aspect, l'invention se rapporte à un dispositif destiné à équiper un joint de dilatation entre deux dalles de béton, le dispositif comprenant deux profils longitudinaux, disposés face à face, de façon à former les bords desdites dalles de béton, le dispositif comprenant des tôles de séparation qui sont respectivement solidaires avec les profils, caractérisé en ce que le dispositif comprend une pluralité de cales insérées dans des orifices ou trous qui se trouvent dans les tôles de séparation, de façon à ce que les cales maintiennent les profils dans un même plan (horizontal). Comme la première forme d'exécution, ce système permet de résoudre le problème de maintient des profils à niveau en phase provisoire, sans nécessiter l'utilisation de profils présentant un grand volume de métal (d'acier).According to another aspect, the invention relates to a device for equipping an expansion joint between two concrete slabs, the device comprising two longitudinal profiles, arranged face to face, so as to form the edges of said concrete slabs, the device comprising separating plates which are respectively integral with the profiles, characterized in that the device comprises a plurality of wedges inserted into holes or holes which are in the separation plates, so that the wedges hold the profiles in the same plane (horizontal). Like the first embodiment, this system makes it possible to solve the problem of maintaining profiles at a provisional level, without requiring the use of profiles having a large volume of metal (steel).

Brève description des figuresBrief description of the figures

La figure 1 décrit un dispositif selon une première forme d'exécution de l'invention.The figure 1 describes a device according to a first embodiment of the invention.

La figure 2 décrit un dispositif selon une autre forme d'exécution de l'invention.The figure 2 describes a device according to another embodiment of the invention.

Description détaillée de plusieurs formes d'exécution de l'inventionDetailed description of several embodiments of the invention

L'invention prévoit donc un dispositif pour équiper un joint de dilatation entre dalles, comprenant deux profils, de préférence des profils métalliques, ledit dispositif comprenant des moyens pour maintenir de façon provisoire, c'est-à-dire avant et pendant la coulée du béton, les deux profils au même niveau dans le plan (horizontal) défini par le niveau de finition du dallage.The invention therefore provides a device for equipping an expansion joint between slabs, comprising two profiles, preferably metal profiles, said device comprising means for temporarily holding, that is to say before and during the casting of the concrete, both profiles at the same level in the (horizontal) plane defined by the level of finish of the pavement.

La figure 1 représente un dispositif selon une première forme d'exécution. Le dispositif comprend deux profils 1a, 1b, de préférence métalliques et rectilignes selon la direction longitudinale du joint, disposés face à face, qui vont former les bords des deux dalles de béton A et B, en équipant donc le joint entre lesdites dalles. Dans la forme d'exécution représentée à la figure 1, les profils 1a et 1b présentent une section de forme essentiellement rectangulaire et identique, ayant donc des faces plates horizontales 10a, 10b du côté inférieur des profils. Des éléments plats verticaux 3a et 3b sont fixés respectivement aux profils 1a et 1b, en dessous de ces profils, c'est-à-dire en dessous de la face inférieure 10a et 10b, et peuvent former des tôles de séparation entre les dalles A et B. Les éléments plats 3a/3b sont assemblés l'un à l'autre de manière provisoire à plusieurs endroits 4 le long du joint, par exemple à l'aide de plusieurs connexions classiques telles que des boulons (vis+écrous) (non montré).The figure 1 represents a device according to a first embodiment. The device comprises two profiles 1a, 1b, preferably metal and rectilinear in the longitudinal direction of the seal, arranged face to face, which will form the edges of the two concrete slabs A and B, thus equipping the joint between said slabs. In the embodiment shown in figure 1 the profiles 1a and 1b have a section of essentially rectangular and identical shape, thus having flat horizontal faces 10a, 10b of the lower side of the profiles. Vertical flat elements 3a and 3b are respectively fixed to the profiles 1a and 1b, below these profiles, that is to say below the lower face 10a and 10b, and can form separating plates between the slabs A and B. The flat members 3a / 3b are temporarily assembled to one another at a plurality of locations along the joint, for example by means of several conventional connections such as bolts (screws + nuts) ( not shown).

L'une des tôles de séparation 3a peut être solidaire d'un élément rigide 5, par exemple une plaque en métal, destiné au transfert de charge. Pour assurer le libre mouvement des deux parties dans le plan des dalles, un fourreau 6 est de préférence posé sur l'élément 5 de transfert de charge, dans l'une des parties du dallage. Puisque le fourreau 6 n'est pas attaché au dispositif, l'élément de transfert de charge ne pourra pas servir à maintenir les profils à niveau avant et pendant la coulée du béton lors de la phase provisoire.One of the separation plates 3a may be integral with a rigid element 5, for example a metal plate, for the charge transfer. To ensure the free movement of the two parts in the plane of the slabs, a sheath 6 is preferably placed on the load transfer element 5, in one of the parts of the tiling. Since the sleeve 6 is not attached to the device, the charge transfer element can not be used to maintain the profiles level before and during casting of the concrete during the provisional phase.

Sur les faces inférieures 10a/10b des profils 1a/1b, plusieurs goujons (ou doguets) d'ancrage 2a/2b peuvent être fixés pour assurer l'ancrage du dispositif dans le béton des dalles A/B.On the lower faces 10a / 10b of the profiles 1a / 1b, several studs (or doguets) anchoring 2a / 2b can be fixed to ensure the anchoring of the device in the concrete slabs A / B.

Les goujons (ou doguets) 2a/2b représentés dans cette forme d'exécution consistent essentiellement en une tôle pliée comprenant une partie plate 11, attachée de manière fixe (de préférence soudée) sur les faces inférieures 10a/10b respectives des profils.The studs (or doguets) 2a / 2b shown in this embodiment consist essentially of a folded sheet comprising a flat portion 11, fixedly attached (preferably welded) to the respective lower faces 10a / 10b of the profiles.

De préférence, chaque goujon (ou doguet) comprend ensuite une partie inclinée 12 et une partie horizontale 13. La partie 11 du goujon (ou doguet) 2a a une longueur telle que ladite partie 11 déborde de la largeur de la face 10a pour servir de support au second profil 1b, sans être assujettie (solidaire) audit second profil. De la même manière, ledit deuxième profil 1b est pourvu de goujons (ou doguets) d'ancrage 2b, qui eux aussi sont pourvus de parties plates 11 qui débordent de la largeur des faces 10b sur lesquelles elles sont soudées, de façon à supporter les profils 1a. De façon avantageuse, les goujons (ou doguets) 2a et 2b sont disposés en alternance sur la longueur du joint. Le support mutuel des profils 1a et 1b par les goujons (ou doguets) 2b et 2a assure le maintien à niveau des bords de dalles, avant et pendant la coulée du béton.Preferably, each stud (or doguet) then comprises an inclined portion 12 and a horizontal portion 13. The portion 11 of the stud (or doguet) 2a has a length such that said portion 11 protrudes from the width of the face 10a to serve as a support to the second profile 1b, without being secured (interdependent) to said second profile. In the same way, said second profile 1b is provided with studs (or doguets) 2b anchor, which are also provided with flat portions 11 which extend beyond the width of the faces 10b on which they are welded, so as to support the profiles 1a. Advantageously, the studs (or doguets) 2a and 2b are arranged alternately along the length of the seal. The mutual support of the profiles 1a and 1b by the studs (or doguets) 2b and 2a ensures the leveling of the slab edges, before and during the pouring of the concrete.

De manière alternative, les goujons (ou doguets) 2a/2b peuvent être soudés sur les tôles de séparation 3a/3b, tout en étant pourvus de parties plates 11 qui se trouvent en dessous et donc en contact avec les faces inférieures 10a/10b des profils (mais pas attachées auxdites faces), de façon à supporter les profils. Il suffit donc que les goujons (ou doguets) d'ancrage soient solidaires avec le dispositif (donc par exemple soudés sur les profils ou soudés sur les tôles de séparation) et qu'ils comprennent des parties 11 qui supportent les profils.Alternatively, the studs (or doguets) 2a / 2b can be welded to the separation plates 3a / 3b, while being provided with flat portions 11 which are below and therefore in contact with the lower faces 10a / 10b of the profiles (but not attached to said faces), so as to support the profiles. It is therefore sufficient that the studs (or doguets) anchoring are integral with the device (thus for example welded to the profiles or welded to the separating plates) and they include parts 11 which support the profiles.

Une autre forme d'exécution est représentée à la figure 2. Selon cette forme, le dispositif est pourvu d'éléments de support 40. Il s'agit de cales 40, de préférence en plastique, qui passent sous les deux profils. Les cales sont insérées dans des orifices ou trous présents dans les tôles de séparation 3a/3b. Les cales ont une première face 41 qui se positionne contre la face inférieure 10a/10b des deux profils 1a/1b, et une deuxième face 42 de l'autre côté, ladite deuxième face étant inclinée vis-à-vis de la première face. Les cales ont donc une hauteur plus élevée à une extrémité du joint. Cette forme permet que les cales soient serrées de façon fixe dans les orifices ou trous, de manière à maintenir les profils 1a/1b dans un même plan.Another embodiment is shown in figure 2 . According to this form, the device is provided with support elements 40. These are wedges 40, preferably made of plastic, which pass under the two profiles. The shims are inserted into holes or holes present in the separating plates 3a / 3b. The shims have a first face 41 which is positioned against the lower face 10a / 10b of the two profiles 1a / 1b, and a second face 42 on the other side, said second face being inclined vis-à-vis the first face. The holds therefore have a higher height at one end of the joint.
