Description

COFFRAGE POUR MURS DE PISCINES EN MACONNERIE
La présente invention a pour objet un coffrage pour murs de piscincs en maçonnerie.FORMWORK FOR MASONRY POOL WALLS
The present invention relates to a formwork for masonry swimming pool walls.

I1 est destiné plus particulièrement à la réalisation d'une paroi verticale de piscine avec arrondi arasant les surfaces verticales tt le fond.I1 is intended more particularly for the realization of a vertical swimming pool wall with rounded off leveling the vertical surfaces tt the bottom.

Jusqu'à ce jour on utilisait pour la confection des dressages des surfaces arrondies en maçonnerie des profils comportant la courbure désirée au moyen de taloches ou autres accessoires manuels, voire des cylindres, qui ne permettaient pas des liaisons sans solution de continuité, et provoquant des stratifications enlevant de l'homogénéité aux liants, bétons ou autres.Up to this day, for the dressing of rounded masonry surfaces, profiles with the desired curvature were used by means of floats or other manual accessories, or even cylinders, which did not allow connections without solution of continuity, and causing stratifications removing homogeneity with binders, concretes or others.

I1 existe également des moules utilisant des éléments courbes se raccordant à des éléments plans grâce à des dispositifs à emboîtements difficiles à nettoyer lors de chaque démontage et remontage. De plus, ces éléments sont assemblés par des entre- toises cn parties hautes et basses constitués de tiges filetées qu'il faut couper après décoffrage avec un outillage approprié. There are also molds using curved elements which are connected to planar elements by means of interlocking devices which are difficult to clean during each disassembly and reassembly. In addition, these elements are assembled by spacers cn upper and lower parts consisting of threaded rods which must be cut after formwork removal with appropriate tools.

Ces éléments n'étant-pas maintenu à leur point de jonction avec la surface horizontale doivent être extrêmement rigides et sont par conséquent lourds et difficiles à manipuler.These elements not being maintained at their junction point with the horizontal surface must be extremely rigid and are therefore heavy and difficult to handle.

Le dispositif suivant la présente invention supprime tous ces inconvénients. En effet, il permet de réaliser par simple coulage la paroi verticale et sa liaison avec un fond horizontal par un arrondi dont les arêtes rejoignent progressivement les surfaces d'appui sans aucune solution de continuité dåns le liant, béton ou autre, tout en étant facile à manipuler et en supprimant la nécessité de couper les entretoises de maintien.The device according to the present invention eliminates all these drawbacks. Indeed, it allows to realize by simple pouring the vertical wall and its connection with a horizontal bottom by a rounded whose edges gradually join the bearing surfaces without any solution of continuity in the binder, concrete or other, while being easy handling and removing the need to cut the retaining spacers.

II est constitué par la combinaison d'abord d'éléments de coffrage extérieurs plans, et intérieurs avec une partie basse arrondie, ces éléments ayant la hauteur du mur à réaliser et étant réalisés préférentiellement en matériau léger telle que résine armée de fibres et nervurée, ensuite d ' un système de maintien constitué d ' une part par un prolongement des armatures å béton dc la dalle horizontale passant sous I 'élément extérieur, d'autre part par des cales pouvant être réglables en hauteur, fixées à l'extrémité de la partie arrondie du moule intérieur et reposant sur l'armature de la dalle horizontale, enfin d'entretoises perdues en béton ou autres fixées aux éléments de coffrage par vis et cavaliers assurant en même temps l'assem- blage des éléments de moule entre eux. It is formed by first combining planar exterior and interior formwork elements with a rounded bottom part, these elements having the height of the wall to be produced and preferably being made of light material such as resin reinforced with fibers and ribbed, then of a holding system consisting on the one hand by an extension of the concrete reinforcements of the horizontal slab passing under the external element, on the other hand by shims which can be adjustable in height, fixed at the end of the rounded part of the interior mold and resting on the frame of the horizontal slab, finally of lost spacers in concrete or other fixed to the formwork elements by screws and jumpers ensuring at the same time the assembly of the mold elements between them.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure l représente en perspective le dispositif dans son ensemble.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure l shows in perspective the device as a whole.

La figure 2 est une coupe horizontale i une échelle différente, à travers une entretoise, suivant les flèches A-A de la figure 1.FIG. 2 is a horizontal section at a different scale, through a spacer, along the arrows A-A of FIG. 1.

La figure 3 est une vue de détail suivant la flèche B de la figure 1, montrant la fixation basse des éléments de coffrage intérieurs dans leur version réglable en hauteur.Figure 3 is a detail view along arrow B of Figure 1, showing the low fixing of the interior formwork elements in their height adjustable version.

La figure 4 est une coupe transversale suivant les flèches C-C de la figure 3.FIG. 4 is a cross section along the arrows C-C of FIG. 3.

Le dispositif, figure 1 à 4, est constitué d'éléments de coffrage extérieurs 3, L et intérieurs 1, 2 reposant sur l'armature 5, 6, 7 de la dalle de fond et assemblés entre eux par entretoises 8 et cavaliers 9.The device, FIGS. 1 to 4, is made up of external formwork elements 3, L and interior 1, 2 resting on the reinforcement 5, 6, 7 of the bottom slab and assembled together by spacers 8 and jumpers 9.

Les éléments de coffrage 1, 2, 3, 4 ont une hauteur supérieure ou égale à celle du mur à réaliser et sont fabriqués en résine armée de fibres renforcée par nervures 10, de manière à présenter un poids permettant une manipulation aisée. Les éléments intérieurs 1, 2 présentent en partie basse une partie courbée il permettant d'obtenir une arête arrondie sans travaux supplémentaires.The formwork elements 1, 2, 3, 4 have a height greater than or equal to that of the wall to be produced and are made of resin reinforced with fibers reinforced with ribs 10, so as to have a weight allowing easy handling. The interior elements 1, 2 have a curved part at the bottom, which makes it possible to obtain a rounded edge without additional work.

Les armatures à béton de la dalle de fond comportent des prolongements 7 passant sous les éléments de moules extérieurs 3, 4 et remontant derrière eux de manière à assurer un maintien en place ferme et précis de leur base.The concrete reinforcements of the bottom slab have extensions 7 passing under the exterior mold elements 3, 4 and rising behind them so as to ensure that their base is kept firm and precise.

Des cales récupérables 12 permettent de solidariser l'extrémité de la partie arrondie 11 des éléments intérieurs de coffrage 1, 2. Ces cales sont constituées d'une partie conique 13 munie d'une rainure 14 s'adaptant sur une armature 6 ainsi qu'une tige filetée 15 et un écrou 16 permettant leur fixation aux éléments de coffrage 1, 2. Recoverable shims 12 make it possible to secure the end of the rounded part 11 of the internal formwork elements 1, 2. These shims consist of a conical part 13 provided with a groove 14 fitting onto a frame 6 as well as a threaded rod 15 and a nut 16 allowing their attachment to the formwork elements 1, 2.

Suivant une variante d'exécution, les cales 12 sont réglables verticalement grâce à une pièce 17 fixée au moule 1, 2, et comportant deux plaques percées 18, 19 emprisonnant l'écrou 16.According to an alternative embodiment, the shims 12 are vertically adjustable by means of a part 17 fixed to the mold 1, 2, and comprising two drilled plates 18, 19 trapping the nut 16.

Les éléments de coffrage 1, 2, 3, 4 sont assemblés entre eux par des entretoises cylindriques en béton 8, abandonnées dans le mur et comportant à chaque extrémité un insert fileté 18, recevant une vis 19, cette dernière assurant également la fixation d'un étrier 9 destiné à l'assemblage des éléments de coffrages conffgus. The formwork elements 1, 2, 3, 4 are assembled together by cylindrical concrete spacers 8, abandoned in the wall and comprising at each end a threaded insert 18, receiving a screw 19, the latter also ensuring the fixing of a bracket 9 intended for the assembly of the formwork elements conffgus.

Grâce à sa facilité d'utilisation, à son poids réduit et à l'économie de main-d'oeuvre qu'il permet, le dispositif qui vient d'être décrit se prête particulièrement bien à la réalisation de coffrages destinés à la confection de piscines de toutes dimensions.Thanks to its ease of use, its reduced weight and the economy of manpower which it allows, the device which has just been described lends itself particularly well to the production of formwork intended for the manufacture of swimming pools of all sizes.

Le positionnement des divers éléments constitutifs donnent à ce dispositif un maximum d'effets utiles qui n'avaient pas été obtenus > i ce jour par des dispositifs similaires. The positioning of the various constituent elements give this device a maximum of useful effects which had not been obtained> i to date by similar devices.
