Chaque élément de support présente une partie supérieure verticale qui s'emboîtera entre les deux branches du profilé en U inversé. Les supports sont fixés au moyen d'un cadre métallique qui est cloué à l'hérissonnage de la dalle, ce cadre est compliqué et coûteux.Document DE-A-2541 030 describes such a set of accessories consisting of a continuous support profile in which another longitudinal profile is fitted. The continuous support profile prevents continuity of the slab below the joint. Document US-A-2 651 243 also describes a set of accessories intended for making withdrawal joints in concrete paving which comprises a front profile in an inverted U shape and a plurality of supports intended to support, at intervals regular, said profile. Each support element has a vertical upper part which will fit between the two arms of the inverted U-shaped profile. The supports are fixed by means of a metal frame which is nailed to the cover of the slab, this frame is complicated and expensive.

La présente invention a pour but de remédier à ces inconvénients. Elle a pour objet un ensemble d'accessoires destiné à la réalisation de joints de retrait et de dilatation d'un dallage en béton conformément au texte de la revendication 1.The present invention aims to remedy these drawbacks. It relates to a set of accessories intended for the production of shrinkage and expansion joints of a concrete paving in accordance with the text of claim 1.

  • FIG. 6 describes a method of implementing these accessories.

La figure 1 décrit un profilé en U inversé 1 destiné à rester en permanence dans le béton et à servir de joint une fois le béton durci.FIG. 1 describes an inverted U-shaped profile 1 intended to remain permanently in the concrete and to serve as a joint once the concrete has hardened.

La figure 2 décrit un profilé en U inversé 2 destiné à être retiré du béton pour créer une saignée comparable à celle réalisée par sciage, et qui sera ultérieurement remplie de mastic afin d'assurer son étanchéité.FIG. 2 describes an inverted U-shaped section 2 intended to be removed from the concrete to create a groove comparable to that produced by sawing, and which will subsequently be filled with mastic in order to ensure its sealing.

Les supports à la figure 3 et à la figure 4 seront décrits successivement.The supports in FIG. 3 and in FIG. 4 will be described successively.

A la figure 1 est indiqué un profilé en U inversé 1 qui comporte deux branches 5. Sur ces deux branches se trouvent deux oreilles 6. Ce profilé s'emboitera parfaitement sur le support 3 et grâce à ses deux oreilles 6, ce profilé restera parfaitement solidaire du béton.In Figure 1 is indicated an inverted U-shaped section 1 which has two branches 5. On these two branches there are two ears 6. This section will fit perfectly on the support 3 and thanks to its two ears 6, this section will remain perfectly integral with concrete.

A la figure 2 est indiqué un profilé en forme de U inversé qui comprend deux branches 7, destiné à être récupéré. Il sera plus étroit en partie inférieure afin de pouvoir s'extraire facilement du béton quand celui-ci aura fait sa prise. Il laissera donc une saignée rectiligne dans le béton ; celle-ci sera ultérieurement mastiquée.In Figure 2 is indicated an inverted U-shaped profile which comprises two branches 7, intended to be recovered. It will be narrower at the bottom so that it can be easily removed from the concrete when it has set. It will therefore leave a straight groove in the concrete; it will be chewed later.

A la figure 3, le support 3 comporte une partie inférieure de section sensiblement trapézoïdale, ayant une grande base située inférieurement, qui est destinée à être noyée dans un béton de mise à niveau. La partie supérieure 9, verticale, est destinée à s'emboîter entre les deux branches 5 ou 7 des profilés en forme de U inversé. A la jonction entre la partie supérieure et la partie inférieure, de part et d'autre de la partie supérieure verticale, se trouvent deux gorges 10 destinées à recevoir l'embase de l'extrémité des branches 5 ou 7 des profilés en forme de U inversé. Les profilés 1 et 2 sont maintenus par les supports 3 qui sont disposés de part en part.In FIG. 3, the support 3 comprises a lower part of substantially trapezoidal section, having a large base situated below, which is intended to be embedded in a leveling concrete. The upper part 9, vertical, is intended to fit between the two branches 5 or 7 of the profiles in the shape of an inverted U. At the junction between the upper part and the lower part, on either side of the vertical upper part, there are two grooves 10 intended to receive the base of the end of the branches 5 or 7 of the U-shaped profiles. reversed. Profiles 1 and 2 are held by supports 3 which are arranged right through.

La figure 4 décrit un support de croisement 4 comportant quatre parties verticales 11 en forme de croix où viennent s'emboîter les profilés 1 ou 2 en forme de U inversé aux intersections des joints.FIG. 4 describes a crossing support 4 comprising four vertical parts 11 in the form of a cross in which the profiles 1 or 2 are fitted in the form of an inverted U at the intersections of the joints.

La figure 5 décrit, à titre d'exemple, un croisement de deux joints, un profilé amovible 2 et un joint permanent 1 maintenus par un joint de croisement 4, le joint 1 étant supporté à une certaine distance par un support 3 décrit précédemment.FIG. 5 describes, by way of example, a crossing of two seals, a removable profile 2 and a permanent seal 1 held by a crossing seal 4, the seal 1 being supported at a certain distance by a support 3 described above.

Comme indiqué à la figure 6, ces différents accessoires seront mis en place la veille du coulage du dallage, et les supports des profilés 3, ainsi que les guides de croisement 4, seront partiellement noyés dans un premier béton ou mortier, afin d'assurer la mise à niveau et la rigidité des profilés 1 ou 2. Ce béton de mise à niveau aura le volume le plus restreint possible. Il assurera le scellement parfait des supports de profilés et guides de croisement, et ne devra pas gêner la pose éventuellement d'un treillis soudé. Le lendemain, comme l'indique la figure 6, les ouvriers pourront couler le béton et assurer sa mise en place à la règle vibrante ou non. Si les profilés 1 ont été choisis, ils resteront dans le béton, et serviront de joint de retrait et de dilatation.As indicated in FIG. 6, these various accessories will be put in place the day before pouring the paving, and the supports for the profiles 3, as well as the crossing guides 4, will be partially embedded in a first concrete or mortar, in order to ensure leveling and stiffness of profiles 1 or 2. This leveling concrete will have the smallest possible volume. It will ensure the perfect sealing of the profile supports and crossing guides, and should not hinder the possible installation of a welded mesh. The next day, as shown in Figure 6, workers can pour the concrete and ensure its placement with the vibrating rule or not. If profiles 1 have been chosen, they will remain in the concrete, and will serve as a withdrawal and expansion joint.

Avec les profilés 2, il faudra les récupérer après la prise du béton et remplir les saignées ainsi réalisées avec un mastic adéquat.With profiles 2, it will be necessary to recover them after setting of the concrete and to fill the grooves thus produced with an adequate sealant.

Ces différents accessoires, objet de l'invention, auront une application pour tous les dallages susceptibles de faire du retrait et où un joint de dilatation s'impose.These various accessories, object of the invention, will have an application for all pavements capable of shrinking and where an expansion joint is required.
