Abstract
Description
Les aires en béton de grande surface, y compris les pistes d'aérodromes et les-autoroutes, sont généralement constituées de dalles dont les bords contigus sont separés par des interstices de 1 ou 2 cm de large obtures par des joints de dilatation. Large-area concrete areas, including aerodrome runways and freeways, generally consist of slabs whose adjoining edges are separated by gaps of 1 or 2 cm wide closed by expansion joints.
Les bords, et plus spécialement les coins, de ces dalles se détériorent à l'usage, mais on peut fréquemment continuer à les utiliser en procédant seulement à une réfection des parties endommagées. The edges, and more particularly the corners, of these tiles deteriorate in use, but one can frequently continue to use them by only repairing the damaged parts.
A cet effet, on découpe et on enlève les parties de béton détériorées, et on coule dans le creux ainsi réalisé du béton neuf, généralement du béton hydraulique ou du béton à base de résine, en ménageant bien entendu avec le bord contigu de la dalle voisine non endommagé l'interstice nécessaire pour la réfection du joint de dilatation qui doit exister entre eux. To this end, the deteriorated concrete parts are cut and removed, and new concrete, generally hydraulic concrete or resin-based concrete, is poured into the hollow thus produced, of course using the contiguous edge of the slab undamaged neighbor the gap necessary for the repair of the expansion joint which must exist between them.
Pour couler ce béton neuf en ménageant cet interstice, on dresse dans le creux ainsi réalisé un élément de coffrage reposant sur le fond de ce creux et prenant appui contre le bord de la dalle contigue non endommagé, ayant l'épaisseur de la largeur désirée pour l'interstice; on peut alors procéder à la coulee du béton neuf et, après prise de celui-ci, on élimine la partie su périeure de cet élément de coffrage et on met en place un mastic, ou un joint préfabriqué, destiné à constituer le joint de dilatation désiré. To pour this new concrete while sparing this gap, a formwork element rests on the bottom of this hollow and rests against the edge of the contiguous undamaged slab, having the thickness of the desired width, in the hollow thus produced. the gap; we can then pour the new concrete and, after setting it, we remove the upper part of this formwork element and we put in place a putty, or a prefabricated joint, intended to constitute the expansion joint longed for.
Cet élément de coffrage doit être découpe dans une plaque de matière suffisamment rigide pour tenir debout dans le creux, contre le bord de la dalle voisine, et sans se déformer, lOgere- ment compressible pour epouser toutes les aspérités du béton ancien du bord de la dalle contigue, susceptible d'être facilement decoupée sur le chantier pour épouser les formes très irrégulières des creux créés dans le bord, et notamment le coinE de la dalle endommagée, et telle qu'on puisse facilement ainer sa partie supérieure pour créer l'interstice dans lequel doit se trouver le joint de dilatation entre le bord rénové de la dalle endommagée et celui de la dalle contigue. This formwork element must be cut from a plate of material rigid enough to stand upright in the hollow, against the edge of the neighboring slab, and without deforming, slightly compressible to match all the roughness of old concrete from the edge of the adjoining slab, capable of being easily cut on the site to match the very irregular shapes of the hollows created in the edge, and in particular the corner of the damaged slab, and such that its upper part can easily be cleared to create the gap in which the expansion joint must be between the renovated edge of the damaged slab and that of the adjoining slab.
Actuellement, on utilise à cet effet des plaques en polystyrène, qui sont compressibles, se découpent facilement, et dont il est facile d'éliminer la partie supérieure; mais elles présentent 1 inconvénient de se déformer trop facilement et, parfois aussi, de flotter sur le béton; les plaques de liège sont suffisamment rigides et compressibles, mais l'élimination de leur partie supérieure s'avère difficile; les plaques en bois, en contreplaqués,ou en particules de bois agglomérées, sont très rigides mais insuffisamment compressibles, et très difficiles à éliminer. Currently, for this purpose, polystyrene plates are used, which are compressible, are easily cut, and the upper part of which is easy to remove; but they have 1 drawback of being too easily deformed and, sometimes also, of floating on concrete; the cork sheets are sufficiently rigid and compressible, but the removal of their upper part is difficult; wooden plates, plywood, or agglomerated wood particles, are very rigid but insufficiently compressible, and very difficult to remove.
La présente invention a pour objet un procédé de rEfec- tion des bords, et notamment des zones endommagées de dalles d'aires en béton du type précité, caractérisé en ce que l'élément de coffrage utilisé est découpé dans une plaque complexe, constituée d'une plaque de matière rigide: et d'une plaque de matière compressible, solidarise entre elles, toutes deux faciles à éliminer, et ayant une épaisseur totale égale à la largeur de 11 interstice désiré, généralement de l'ordre de 1 à 2 cm. ou plus
On peut, par exemple, utiliser une plaque complexe constituée d'une plaque de plâtre et d'une plaque de polystyrène, collées l'une à l'autre, le plâtre rigidifiant l'ensemble, le polystyrène assurant la compressibilité désirée, l'ensemble étant indéformable, facile à découper sur le chantier, et l'élimination de sa partie supérieure ne présentant aucune difficulté.The subject of the present invention is a process for the reinforcement of the edges, and in particular of the damaged areas of concrete area slabs of the aforementioned type, characterized in that the formwork element used is cut from a complex plate, consisting of '' a plate of rigid material: and a plate of compressible material, integral with each other, both easy to remove, and having a total thickness equal to the width of the desired interstice, generally of the order of 1 to 2 cm . or more
One can, for example, use a complex plate consisting of a plasterboard and a polystyrene plate, glued to each other, the plaster stiffening the assembly, the polystyrene ensuring the desired compressibility, the assembly being undeformable, easy to cut on site, and the elimination of its upper part presenting no difficulty.
C'est ainsi que de très bons resultats ont été obtenus en utilisant une plaque complexe constituée d'une plaque de pla- tre de 7 SlOmm d'épaisseur environ, par exemnle, qu'on trouve dans le commerce, sur laquelle on a collé une plaque de polystyrène de 5 à 20 nom d'épaisseur, par exemple, qu'on trouve également dans le commerce; une telle plaque complexe est facile à débiter par tron çonnage sur le chantier. This is how very good results have been obtained by using a complex plate consisting of a plaster plate of approximately 7 mm thickness, for example, which is commercially available, to which we have stuck. a polystyrene plate 5 to 20 mm thick, for example, which is also commercially available; such a complex plate is easy to cut by sectioning on the site.
Le dessin annexé montre à titre d'exemple un mode de réalisation de la présente invention dans le cas de réfection d'une zone de dalle endommage,mais qui peut s'appliquer à toute réfection de bord de dalle en béton. The accompanying drawing shows by way of example an embodiment of the present invention in the case of repairing a damaged slab area, but which can be applied to any repair of the edge of a concrete slab.
La figure 1 est une vue en plan, après enlèvement de la zone endommagée. Figure 1 is a plan view, after removal of the damaged area.
La figure 2 est une vue en coupe faite suivant la ligne
II-II de la figure 1.Figure 2 is a sectional view taken along the line
II-II of Figure 1.
La figure 3 est une vue analogue après réfection de la zone endommagée. Figure 3 is a similar view after repair of the damaged area.
La figure 4 est une vue partielle, à plus grande échelle, de celle de la figure 3. FIG. 4 is a partial view, on a larger scale, of that of FIG. 3.
Comme le montre la figure 1, on découpe et on enlève la zone 1 endommagée de la dalle 2 qui est séparée des dalles contigues 3 et 4 par des interstices 5 et 6 obturés par des joints de dilatation appropriés 7 et 8. As shown in FIG. 1, the damaged area 1 is cut out and removed from the slab 2 which is separated from the adjoining slabs 3 and 4 by interstices 5 and 6 closed by suitable expansion joints 7 and 8.
On découpe ensuite deux éléments de coffrage destinés à être posés sur le fond du creux créé par l'enlèvement de la zone 1, contre les bords des dalles contigues 3 et 4, et débordant légèrement au-dessus des faces supérieures de ces dalles 2 à 4, et on remplit ce creux avec un béton neuf 9; quand celui-ci a suffisamment fait prise, on élimine la partie superieure 10 des éléments de coffrage qu on remplace par un mastic 11 ou un tronçon de joint préfabriqué. Then cut two formwork elements intended to be placed on the bottom of the hollow created by the removal of zone 1, against the edges of the adjoining slabs 3 and 4, and projecting slightly above the upper faces of these slabs 2 to 4, and this hollow is filled with new concrete 9; when the latter has sufficiently set, the upper part 10 is removed from the formwork elements which are replaced by a putty 11 or a section of prefabricated joint.
Ces éléments de coffrage rigides, compressibles, susceptibles d'être aisément découpés sur le chantier et faciles à éliminer sont constitués d'une plaque complexe, constituée d'une plaque rigide 12, en plâtre par exemple, et d'une plaque de matigre compressible 13, en polystyrène par exemple, solidarisées par tous moyens appropriés, notamment par collage. These rigid, compressible shuttering elements, capable of being easily cut on the site and easy to dispose of, consist of a complex plate, consisting of a rigid plate 12, of plaster for example, and a plate of compressible matigre. 13, made of polystyrene for example, secured by any appropriate means, in particular by gluing.
I1 est bien entendu que le mode de réalisation qui a été décrit ci-dessus en référence au dessin annexé a été donné à titre purement indicatif et nullement limitatif et que de nombreuses modifications peuvent être apportées sans qu'on stécarte pour cela du cadre de la présente invention. It is understood that the embodiment which has been described above with reference to the appended drawing has been given for information only and is in no way limitative and that numerous modifications can be made without departing from the scope of the present invention.
