Description

La présente invention se rapporte à un joint de structure pour dalles en matériau moulable et en particulier pour dalles en matériau à liant hydraulique tel que le béton.The present invention relates to a structural joint for slabs of moldable material and in particular for slabs of hydraulic binder material such as concrete.

Pour la réalisation de grandes surfaces en béton, il est recommandé de répartir la surface en dalles de béton ayant des dimensions bien déterminée. Entre les différentes dalles, il convient de prévoir, sur les bords des dalles, des éléments métalliques appelés joints de structure permettant d'une part, le retrait ou dilatation thermique ainsi que la reprise d'écarts de dimensions ou d'angle et d'autre part le renforcement des bords mêmes des matériaux moulables à liant du type hydraulique ou non, tel que des dalles de béton.For the production of large concrete surfaces, it is recommended to distribute the surface in concrete slabs having well defined dimensions. Between the different slabs, provide, on the edges of the slabs, metallic elements called structural joints allowing, on the one hand, shrinkage or expansion thermal as well as the recovery of dimensional or angle deviations and on the other hand strengthening the very edges of moldable materials with a binder of the hydraulic type or not, such as concrete slabs.

Actuellement, le renforcement des dalles de béton est couramment réalisé à l'aide de joints fabriqués à partir de profils en tôle d'acier.Currently, the reinforcement of concrete slabs is commonly made using gaskets made from sheet metal profiles of steel.

Différents types de joints métalliques ont été proposés de manière à créer un effet de renforcement sur le matériau composite à l'endroit des joints. Cet effet de renforcement dépend essentiellement des caractéristiques géométriques et mécaniques des joints qui ont été mis en oeuvre.Different types of metal seals have been proposed from so as to create a reinforcing effect on the composite material to the location of the joints. This strengthening effect essentially depends geometric and mechanical characteristics of the joints which have been implemented.

De manière à pouvoir comparer objectivement plusieurs types différents de joints de structure, il est utile de rappeler le comportement et le processus de renforcement de l'arrête vive d'un matériau composite à matrice fragile. In order to be able to objectively compare several different types of structural joints, it is worth remembering the behavior and the process of strengthening the sharp edge of a composite material with a fragile matrix.

Ce comportement dépend de l'effet de renfort de la matrice au voisinage des arrêtes vives soumises aux épaufrements et aux efforts de cisaillement.This behavior depends on the reinforcing effect of the matrix in the vicinity of sharp edges subject to spalling and efforts shear.

Le renforcement des extrémités des dalles devrait idéalement répondre aux critères suivants :

  • la protection adéquate de l'arrête,
  • l'ancrage positif pour éviter le décollement,
  • un emboítement tenon et mortaise,
  • la nécessité de réaliser une épaisseur suffisante de matière pour éviter le cisaillement de la dalle aux points faibles, dus au dessin géométrique du profil métallique.
The reinforcement of the ends of the slabs should ideally meet the following criteria:
  • adequate edge protection,
  • positive anchoring to avoid detachment,
  • a tenon and mortise interlocking,
  • the need to achieve a sufficient thickness of material to avoid shearing of the slab at weak points, due to the geometric design of the metal profile.

L'invention se rapporte donc à un joint de structure, par exemple en acier, destiné à renforcer les arrêtes d'un matériau de matrice ou dalle, par exemple le béton, en ne se déchaussant jamais hors de celui-ci, ni du fait du joint lui-même, ni du fait de la matrice par rupture de celle-ci au voisinage de l'ancrage.The invention therefore relates to a structural joint, by example in steel, intended to reinforce the edges of a material of matrix or slab, for example concrete, never taking off your shoes out of it, neither because of the joint itself, nor because of the matrix by breaking it in the vicinity of the anchor.

A cet effet, le joint de renforcement comporte un emboítement mâle et femelle décalé vers le bas par rapport à la ligne médiane de la dalle pour obtenir une épaisseur de matrice plus importante au-dessus de l'emboítement en vue d'obtenir une résistance accrue contre les charges de sollicitations externes.For this purpose, the reinforcement joint includes a male and female socket offset downward from the line median of the slab to obtain a greater matrix thickness important above the socket in order to obtain resistance increased against external stress loads.

Ainsi, il existe déjà des joints du genre à profil double à emboítement mâle et femelle en forme de U tel que à tenon et mortaise qui s'opposent au déplacements verticaux relatifs des deux demi-dalles.Thus, there are already seals of the double profile type with male and female U-shaped socket such as tenon and mortise which oppose the relative vertical displacements of the two half-slabs.

Les profils sont solidaires des dalles en béton, grâce aux ancrages par fers à bétons soudés aux profils.The profiles are integral with the concrete slabs, thanks to the concrete iron anchors welded to the profiles.

Un joint de structure couramment utilisé est réalisé à l'aide d'un double profil en substance en forme de oméga dont le contour extérieur de l'un épouse le contour intérieur de l'autre. La partie centrale mâle du joint doit nécessairement présenter un volume suffisant pour permettre son remplissage par le matériau moulable.A commonly used structural joint is made using of a double profile essentially in the shape of an omega whose outline the exterior of one follows the interior contour of the other. The part central male joint must necessarily have a volume sufficient to allow it to be filled with the moldable material.

Pour une épaisseur constante de la dalle et dans le cas où la partie supérieure du joint doit être augmentée pour des raisons de capacités de reprise de charges importantes, la partie inférieure du joint devient automatiquement insuffisante et, par conséquent, cette partie inférieure qui ne sera plus capable de supporter lesdites charges par manque d'épaisseur de la matrice.For a constant thickness of the slab and in the case where the upper part of the joint must be increased for reasons of large load carrying capacities, the lower part of the joint automatically becomes insufficient and, therefore, this part lower which will no longer be able to support said loads by lack of thickness of the matrix.

Il en résulte qu'il est nécessaire de pouvoir disposer de nombreux modèles de joints à hauteurs différents.It follows that it is necessary to have access to many models of joints with different heights.

Un autre problème rencontré avec ce genre de profils est que, en cas de hauteur limité de la dalle de béton, les dimensions minimum du profil en forme de oméga reste malgré tout très important à cause du volume nécessaire de la partie centrale mâle du joint.Another problem encountered with this kind of profiles is that, in the event of a limited height of the concrete slab, the dimensions minimum omega-shaped profile remains very important despite everything because of the necessary volume of the central male part of the seal.

Il en résulte que la masse de béton qui subsiste dans la partie supérieur du bord de la dalle, situé au-dessus de l'emboítement du profil, est largement insuffisant pour pouvoir résister aux charges normales sur la surface de la dalle et que, par conséquent, cette partie est exposée aux dégradations par fissuration ou par épaufrement du béton.As a result, the mass of concrete that remains in the upper part of the edge of the slab, located above the socket profile, is largely insufficient to be able to resist loads normal on the surface of the slab and that, therefore, this part is exposed to damage by cracking or spalling of the concrete.

Le but de la présente invention est de remédier aux inconvénients cités ci-dessus par des moyens simples et efficaces qui seront décrit plus en détail dans la description qui suit.The object of the present invention is to remedy the disadvantages mentioned above by simple and effective means which will be described in more detail in the following description.

A cet effet, le joint de structure conforme à l'invention comporte les caractéristiques telles que spécifiées dans les revendications repris en fin de description.To this end, the structural joint according to the invention has the characteristics as specified in the claims included at the end of the description.

Afin de bien comprendre l'invention, un exemple de joint de structure existant, ainsi que plusieurs variantes de réalisation du joint selon l'invention seront décrit ci-après à l'aide des dessins annexés dans lesquels :

  • la figure 1 : montre, en coupe transversale, un joint de structure réalisé à l'aide de profils selon l'art de la technique connue;
  • la figure 2 : est une coupe transversale d'un joint de structure conforme à l'invention en position fermée;
  • la figure 3 : est une vue identique à la figure 2 mais avec le joint en position rétractée;
  • la figure 4 : est une vue en coupe transversale d'un joint selon l'invention réalisé à l'aide de profils laminés à chaud;
  • les figures 5 et 6 : sont des variantes de réalisations de joints de structure selon l'invention.
    • In order to fully understand the invention, an example of an existing structural joint, as well as several alternative embodiments of the joint according to the invention will be described below with the aid of the appended drawings in which:
  • Figure 1: shows, in cross section, a structural joint made using profiles according to the art of the known technique;
  • Figure 2: is a cross section of a structural joint according to the invention in the closed position;
  • Figure 3: is a view identical to Figure 2 but with the seal in the retracted position;
  • Figure 4: is a cross-sectional view of a joint according to the invention produced using hot-rolled profiles;
  • Figures 5 and 6: are alternative embodiments of structural joints according to the invention.

    • Sur la figure 1 est représenté un joint de structure 10, selon l'état de la technique connu, comprenant deux profils métalliques disposés tout au long des bords adjacents de deux dalles de béton 20, 22.In FIG. 1 is shown a structural joint 10, according to the known state of the art, comprising two metal profiles arranged along the adjacent edges of two concrete slabs 20, 22.

    Le joint 10 est constitué par un profil formant une partie mâle 12, ancrée dans le bord de la dalle 20, et un profil formant une partie femelle 14, ancrée dans la bord de la dalle 22.The seal 10 is constituted by a profile forming a part male 12, anchored in the edge of the slab 20, and a profile forming a female part 14, anchored in the edge of the slab 22.

    Les parties mâle et femelle 12, 14 des profils sont munies d'ailerons qui s'étendent vers le haut et vers le bas de manière à épouser respectivement l'arrête de la surface supérieure et l'arrête de la surface inférieure des dalles de béton 20, 22.The male and female parts 12, 14 of the profiles are provided fins which extend upwards and downwards so as to marry respectively stops the upper surface and stops the surface bottom of the concrete slabs 20, 22.

    L'ancrage des profils 12 et 14 est réalisé habituellement à l'aide de fers à béton 16 répartis sur la longueur desdits profils.The anchoring of profiles 12 and 14 is usually carried out at using concrete irons 16 distributed over the length of said profiles.

    Ainsi qu'on peut le constater, la partie mâle 12 du profil dispose d'une cavité 18 qui doit être remplie de matière moulable tel que du béton et ne peut, par conséquent, ne pas être réduite en dimension car, dans ce cas, le béton aura difficile d'y pénétrer.As can be seen, the male part 12 of the profile has a cavity 18 which must be filled with moldable material such only concrete and therefore cannot be reduced to dimension because, in this case, the concrete will be difficult to penetrate.

    En plus, la distance "d", entre le côté supérieur 15 du profil femelle 14 et la surface 23 de la dalle de béton 22, est fort limitée, d'ou risque réelle de fissuration et épaufrement selon une ligne de rupture 24.In addition, the distance "d" between the upper side 15 of the female profile 14 and the surface 23 of the concrete slab 22, is strong limited, or real risk of cracking and spalling along a line rupture 24.

    Une forme de réalisation d'un joint selon l'invention est représenté à la figure 2.One embodiment of a joint according to the invention is shown in figure 2.

    Conformément à cette réalisation, le joint de structure 30 est constitué de deux profils de forme particulière qui s'emboítent également en tant que tenon et mortaise.In accordance with this embodiment, the structural joint 30 consists of two profiles of particular shape which fit together also as a tenon and mortise.

    La partie mâle 32, est réalisé à l'aide d'une tôle en substance en forme de L dont l'aile verticale s'étend jusqu'à la l'arrête de la surface supérieure de la dalle 20 et dont l'aile de base 31 est repliée vers le bas de façon à créer une seconde aile inférieure 33 replié tout contre la première et dont l'extrémité peut s'étendre au-delà de l'aile verticale pour former un talon 29 d'ancrage dans le béton.The male part 32 is produced using a sheet metal L-shaped substance whose vertical wing extends to the ridge of the upper surface of the slab 20 and whose base wing 31 is folded down to create a second lower wing 33 folded all against the first and whose end may extend beyond the vertical wing to form a heel 29 for anchoring in the concrete.

    La partie femelle 34 du joint 30, est également réalisé à l'aide d'une tôle en substance en forme de L dont l'aile verticale s'étend jusqu'à l'arrête de la surface supérieure de la dalle 22 et dont l'aile de base 35 est replié vers le bas de façon à créer une seconde branche inférieure 37 disposé parallèlement à la première branche 35 tout en laissant entre-elles une espace 36 dans laquelle peut s'engager les branches repliées 31, 33 du profil mâle 32.The female part 34 of the seal 30, is also produced at using a substantially L-shaped sheet with a vertical wing extending up to the stop of the upper surface of the slab 22 and the wing of which base 35 is folded down to create a second branch lower 37 arranged parallel to the first branch 35 while leaving between them a space 36 in which can engage the folded branches 31, 33 of the male profile 32.

    Comme on peut le constater, la distance "D" entre l'aile de base 35 du profil femelle 34 et la surface 23 de la dalle de béton 22 est largement supérieure que sur la figure 1 et la masse de béton peut facilement supporter les charges importantes le long du bord de la dalle de béton 22.As can be seen, the distance "D" between the wing of base 35 of the female profile 34 and the surface 23 of the concrete slab 22 is much greater than in Figure 1 and the mass of concrete can easily support heavy loads along the edge of the slab concrete 22.

    Généralement, on peut aussi prévoir un profilé, tel qu'une cornière 38, fixé sur la partie inférieure 37 du profil femelle 34 pouvant servir comme pièce de distance lors du moulage de la dalle.Generally, one can also provide a profile, such as a angle 38, fixed on the lower part 37 of the female profile 34 which can serve as a distance piece when molding the slab.

    Cette cornière 38 s'étend de préférence jusqu'à l'arrête de la surface inférieure de la dalle de béton 22.This angle 38 preferably extends to the stop of the lower surface of the concrete slab 22.

    La figure 4 montre une réalisation équivalente selon l'invention.Figure 4 shows an equivalent embodiment according to the invention.

    Ici les profils sont laminés à chaud et la partie femelle 54 présente une forme de L en image miroir solidaire du bord de la dalle de béton 20 et dont l'aile verticale 47 s'étend jusqu'à l'arrête de la surface supérieure de cette dalle. L'aile de base 55 s'étend vers l'intérieure de la dalle et est repliée vers le bas pour former une double aile 57 qui s'étend parallèlement avec l'aile de base 55 en laissant une espace réduite 56 entre-elles.Here the profiles are hot rolled and the female part 54 has an L-shaped mirror image integral with the edge of the slab of concrete 20 and the vertical wing 47 of which extends to the stop of the upper surface of this slab. The base wing 55 extends towards the inside of the slab and is folded down to form a double wing 57 which extends parallel with the base wing 55 leaving a reduced space 56 between them.

    La partie mâle 52 est également en forme de L en image miroir et est solidaire du bord de la dalle de béton 22.The male part 52 is also L-shaped in image mirror and is integral with the edge of the concrete slab 22.

    L'aile verticale 58 s'étend jusqu'à l'arrête de la surface supérieure de la dalle et l'aile de base 51 s'étend vers l'extérieure à partir du bord de la dalle 22 et est muni d'un talon 59 qui s'étend vers l'intérieur de la dalle 22.The vertical wing 58 extends to the edge of the surface upper of the slab and the base wing 51 extends outwards from the edge of the slab 22 and is provided with a heel 59 which extends towards inside the slab 22.

    Comme montré aux figures 5 et 6, qui sont deux variantes de réalisation de l'invention, le bord de l'une des dalles 22 est rendu solidaire d'un profil femelle 34 similaire de la figure 2.As shown in Figures 5 and 6, which are two variants of the invention, the edge of one of the slabs 22 is rendered secured to a female profile 34 similar to FIG. 2.

    Par contre, dans cette réalisation, le bord de l'autre dalle 20 est rendu solidaire d'un second profil femelle 43 disposée en image miroir par rapport du premier profil femelle 34.By cons, in this embodiment, the edge of the other slab 20 is made integral with a second female profile 43 arranged in image mirror relative to the first female profile 34.

    Dans ce cas la partie mâle est constitué d'une pièce plate indépendante 40 dont une extrémité 41 peut s'engager dans le premier profil femelle 34 et dont l'autre extrémité 42 peut s'engager dans le second profil femelle 43.In this case the male part consists of a flat part independent 40 of which one end 41 can engage in the first female profile 34 and whose other end 42 can engage in the second female profile 43.

    A la figure 6, les extrémités supérieures des profils femelles 34 et 43 sont munies de longerons 45 et 46 formant des bords supérieurs des deux dalles de béton adjacents.In Figure 6, the upper ends of the profiles females 34 and 43 are provided with side members 45 and 46 forming edges top of the two adjacent concrete slabs.

    Grâce à l'invention, on obtient donc un joint de structure composé de profils dont la partie mâle/femelle est très compacte par rapport aux joints existants.Thanks to the invention, a structural joint is therefore obtained. composed of profiles whose male / female part is very compact by compared to existing joints.

    De ce fait, de grands mouvements sont possibles dans le plan horizontal tout en permettant la reprise de charges importantes sans jeu excessif au niveau du joint.Therefore, large movements are possible in the horizontal plane while allowing the recovery of large loads without excessive play at the joint.

    Grâce au nouveau profil du joint de structure selon l'invention, il n'y a plus de problèmes de remplissage de la partie centrale de la partie mâle.Thanks to the new profile of the structural joint according to the invention, there are no more filling problems with the part central part of the male part.

    Les zones supérieures et inférieures du bord de la dalle, situées de part et d'autre de la partie mâle/femelle du joint et qui sont à remplir par le matériau moulable, sont augmentées en épaisseur et garantissent une résistance au cisaillement optimale.The upper and lower areas of the edge of the slab, located on either side of the male / female part of the seal and which are fill with moldable material, are increased in thickness and guarantee optimum shear strength.

    Le nouveau profil permet ainsi une utilisation dans une gamme d'épaisseurs différentes de la dalle ou matrice.The new profile thus allows use in a range of different thicknesses of the slab or matrix.

    Dans le cas de dalles de béton de faible épaisseur, il devient possible de décaler la zone d'emboítement mâle/femelle vers le bas par rapport à la ligne médiane de la dalle, permettant ainsi de plus fortes épaisseurs de matrice aux endroits fragiles tout en assurant ce rôle aussi bien en position ouverte que fermée du joint.In the case of thin concrete slabs, it becomes possible to shift the male / female nesting area towards the low relative to the center line of the slab, allowing more large matrix thicknesses in fragile areas while ensuring role both in the open and closed position of the seal.

    Ce décalage est obtenu grâce au faible encombrement de la partie mâle de l'emboítement constitué d'une pièce métallique ou non, compacte et rigide assurant une grande résistance de l'emboítement.This offset is obtained thanks to the small size of the male part of the socket consisting of a metallic part or not, compact and rigid ensuring high nesting resistance.

    La partie mâle étant massive, grâce à l'invention, il n'y a plus de problèmes de son remplissage et la diminution de son encombrement se fait au bénéfice des sections de matrice supérieure et inférieure, garantissant une résistance optimale des bords de dalles.The male part being massive, thanks to the invention, there is more problems with its filling and the decrease in its bulk is done for the benefit of the upper matrix sections and lower, ensuring optimal resistance of the edges of the slabs.

    Bien sur, les réalisations selon l'invention sont décrits et illustrés à titre d'exemples et d'autres variantes de réalisations restent possibles sans pour autant sortir du cadre de la présente invention.Of course, the embodiments according to the invention are described and illustrated by way of examples and other variant embodiments remain possible without departing from the scope of the present invention.
