Description

La présente invention a pour objet un dispositif de fixation de banches de coffrage pour la mise en oeuvre d'un procédé de réalisation de murs reliés par leur base à un radier, pour former un bassin de piscine en béton banché, armé et vibré en une seule coulée. On sait que réaliser un bassin de piscine en béton banché et vibré en une seule coulée constitue le procédé qui procure le meilleur résultat du point de vue solidité et tenue dans le temps, notamment en raison de la parfaite cohésion au niveau de la liaison entre les parois verticales et le radier. De manière habituelle les parois verticales sont réalisées par coulage de béton entre deux banches parallèles entretoisées par des étrésillons, et maintenues extérieurement par des étais. Pour pouvoir couler en une fois les murs et le radier, on surélève les banches au moyen d'éléments de construction pour libérer inférieurement un espace d'une hauteur correspondant à l'épaisseur du radier. Après mise en place du matériel, le radier est coulé puis, alors que le béton est encore frais, on coule le béton entre les banches. The subject of the present invention is a device for fastening shuttering posts for the implementation of a method of making walls connected by their base to a raft, in order to form a pool basin made of reinforced concrete, reinforced and vibrated in one. only casting. It is known that making a swimming pool basin concrete banché and vibrated in a single casting is the process that provides the best result from the point of view of strength and durability, particularly because of the perfect cohesion in the connection between the vertical walls and the raft. Usually the vertical walls are made by pouring concrete between two parallel banks braced by braces, and held externally by props. In order to be able to pour the walls and the raft at once, the raised panels are elevated by means of building elements in order to release less a space of a height corresponding to the thickness of the slab. After placing the material, the floor is poured and then, while the concrete is still fresh, the concrete is poured between the boards.

Le matériel actuellement utilisé pour la mise en oeuvre d'un tel procédé ne donne pas entière satisfaction, aussi bien du point de vue du résultat obtenu, que de son utilisation. La présente invention a pour but de proposer un dispositif de fixation de banches de coffrage permettant de remédier à ces inconvénients en étant notamment d'une utilisation aisée. Selon l'invention, le dispositif de fixation de banches de coffrage pour la mise en oeuvre d'un procédé de réalisation de murs reliés par leur base à un radier, pour former un bassin de piscine en béton banché, armé et vibré en une seule coulée, comprend des moyens conçus aptes à maintenir deux banches parallèles et à une certaine distance du sol, et est utilisé en au moins deux exemplaires pour chaque paire de banches, et il se caractérise essentiellement en ce que lesdits moyens comprennent: - une entretoise haute destinée à être assujettie aux banches sur le bord supérieur de celles-ci, et qui comprend des moyens permettant de maintenir l'écartement desdites banches, - une entretoise basse sur laquelle reposent, par leur bord inférieur, lesdites banches, et qui comprend des moyens permettant de maintenir l'écartement desdites banches, - une semelle destinée à reposer au sol, et qui porte ladite entretoise basse, au travers d'un système réglable en hauteur, - un élément de liaison qui relie les deux entretoises, et qui est associé à des moyens de réglage de sa longueur, en sorte de permettre le bridage desdites banches entre lesdites entretoises. Selon une caractéristique additionnelle du dispositif selon l'invention, chacune des entretoises, haute ou basse, se présente sous la forme d'une barre sur le bord longitudinal duquel sont pratiquées deux encoches destinées chacune à recevoir le bord d'une banche, et espacées de la largeur d'écartement desdites banches. The equipment currently used for the implementation of such a method is not entirely satisfactory, both from the point of view of the result obtained, and its use. The object of the present invention is to propose a device for fastening formwork panels which makes it possible to remedy these drawbacks, in particular by being easy to use. According to the invention, the device for fixing formwork panels for the implementation of a method of making walls connected by their base to a floor, to form a pool pool concrete banché, armed and vibrated in one casting, comprises means designed to maintain two parallel banks and at a distance from the ground, and is used in at least two copies for each pair of boards, and it is essentially characterized in that said means comprise: - a high spacer intended to be subject to the boards on the upper edge thereof, and which comprises means for maintaining the spacing of said panels, - a low spacer on which rest, by their lower edge, said panels, and which comprises means to maintain the spacing of said panels, - a sole intended to rest on the ground, and which carries said low spacer, through a system adjustable in height, - A connecting element which connects the two spacers, and which is associated with means for adjusting its length, so as to allow the clamping of said panels between said spacers. According to an additional feature of the device according to the invention, each of the spacers, high or low, is in the form of a bar on the longitudinal edge of which are formed two notches each intended to receive the edge of a banche, and spaced apart of the width of said banches.

Selon une autre caractéristique additionnelle du dispositif selon l'invention, le système réglable en hauteur qui relie la semelle à l'entretoise basse consiste en un vérin à vis. Selon une autre caractéristique additionnelle du dispositif selon l'invention, l'élément de liaison qui relie les eux entretoises consiste en un fer à béton solidarisé à chacune desdites entretoises, à savoir à l'entretoise basse par soudage, et à l'entretoise haute au travers des moyens de réglage. Selon une autre caractéristique additionnelle du dispositif selon l'invention, le fer à béton comporte un segment coudé au niveau de sa solidarisation à l'entretoise basse, en sorte qu'un prolongement s'étende sensiblement parallèlement à l'axe principal des entretoises, pour former au moins en partie l'armature du radier. Selon une autre caractéristique additionnelle du dispositif selon l'invention, les moyens de réglage de la longueur de l'élément de liaison consistent en un système vis écrou solidaire de l'entretoise haute, et dont une extrémité est apte à être accrochée audit élément de liaison. Les avantages et les caractéristiques du dispositif selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif. Dans le dessin annexé : - la figure 1 représente une vue schématique en perspective d'un dispositif de fixation de banches de coffrage selon 10 l'invention. - la figure 2 représente une vue schématique en perspective d'une paire de banches équipées d'un dispositif de fixation de banches de coffrage selon l'invention. - la figure 3 représente une vue schématique en élévation 15 et en coupe du même système de fixation de banches de coffrage selon l'invention. En référence à la figure 1, on peut voir un dispositif 1 de fixation de banches de coffrage selon l'invention. Ce dispositif 1 comprend deux entretoises, à savoir une entretoise haute 2 et 20 une entretoise basse 3, reliées par un élément de liaison 4. L'entretoise haute 2 se présente sous la forme d'une barre 20 dont le bord inférieur est muni de deux encoches 21 et 22 dont la distance d'espacement correspond à l'épaisseur qu'il est prévu de donner à la paroi à construire. 25 De manière identique, l'entretoise basse 3 se présente sous la forme d'une barre 30 dont le bord supérieur est muni de deux encoches 31 et 32 dont la distance d'espacement correspond à l'épaisseur qu'il est prévu de donner à la paroi à construire. L'entretoise basse 3 est solidarisée à un vérin à vis 33, 30 lui-même solidaire d'une semelle 34, en sorte de permettre de régler en hauteur le positionnement de l'entretoise basse 3 par rapport au sol. L'élément de liaison 4 consiste en un fer à béton 40 qui présente un segment rectiligne 41 s'étendant entre les deux 35 entretoises 2 et 3, et qui est soudé par une extrémité à l'entretoise basse 3, tandis que son autre extrémité présente des moyens d'accrochage, en l'occurrence une boucle 42, permettant son assujettissement à un dispositif de bridage 5 solidaire de l'entretoise haute 2. Le dispositif de bridage 5 comprend une tige filetée 50 qui traverse librement l'entretoise haute 2 de haut en bas dont l'extrémité disposée du côté des encoches 21 et 22 est munie d'un crochet 51 destiné à coopérer avec la boucle 42, tandis qu'un écrou 52 est vissée sur la tige filetée 50 de l'autre côté de l'entretoise haute 2. On comprendra que selon que l'on visse ou dévisse l'écrou 52, le crochet 51 se rapproche, ou respectivement s'éloigne, de l'entretoise haute 2. On notera que le fer à béton 40 comporte, en prolongement du segment rectiligne 41, au niveau de sa solidarisation à l'entretoise basse 3, un segment coudé 43 lui-même prolongé d'une partie rectiligne 44 qui s'étend transversalement, sensiblement parallèlement à l'axe longitudinal de l'entretoise basse 3. En référence maintenant à la figure 2, on peut voir deux banches 6 et 7, respectivement intérieure et extérieure, maintenues verticalement et parallèlement au moyen de deux dispositifs 1 de fixation selon l'invention. La banche intérieure 6 repose dans les encoches 31, dont une seule est visible, des deux entretoises basses 3, tandis que la banche extérieure 7 repose dans les encoches 32 des mêmes entretoises basses. Chacune des entretoises basses 3 repose au sol par l'intermédiaire d'une semelle 34, et à la hauteur choisie, ce qui est obtenu au travers du vérin à vis 33. Les banches intérieure 6 et extérieure 7 sont également maintenues supérieurement par les entretoises hautes 2, au travers des encoches 21 et 22, et sous l'action du dispositif de bridage 5. Par le serrage de l'écrou 52, qui en l'occurrence est muni d'ailettes 53 de manutention, contre l'entretoise haute 2, on provoque la remontée de la tige filetée 50, et donc une traction sur le fer à béton 40, immobilisant ainsi les banches 6 et 7 entre les entretoises 2 et 3. According to another additional feature of the device according to the invention, the height-adjustable system which connects the sole to the low spacer consists of a screw jack. According to another additional feature of the device according to the invention, the connecting element which connects them spacers consists of a concrete iron secured to each of said spacers, namely to the low spacer by welding, and to the high spacer through the adjustment means. According to another additional feature of the device according to the invention, the concrete reinforcing bar has a bent segment at its fastening to the low spacer, so that an extension extends substantially parallel to the main axis of the spacers, to form at least in part the frame of the raft. According to another additional feature of the device according to the invention, the means for adjusting the length of the connecting element consist of a nut screw system integral with the high spacer, and one end of which is capable of being hooked to said element of link. The advantages and characteristics of the device according to the invention will emerge more clearly from the description which follows and which refers to the appended drawing, which represents a non-limiting embodiment thereof. In the accompanying drawing: - Figure 1 shows a schematic perspective view of a fastening formwork shuttering device according to the invention. - Figure 2 shows a schematic perspective view of a pair of panels equipped with a shuttering formwork fastening device according to the invention. - Figure 3 shows a schematic elevational view 15 and in section of the same shuttering formwork fastening system according to the invention. With reference to FIG. 1, there can be seen a device 1 for fixing formwork panels according to the invention. This device 1 comprises two spacers, namely a high spacer 2 and a low spacer 3, connected by a connecting element 4. The upper spacer 2 is in the form of a bar 20 whose lower edge is provided with two notches 21 and 22 whose spacing distance corresponds to the thickness that is expected to give the wall to build. Similarly, the lower spacer 3 is in the form of a bar 30 whose upper edge is provided with two notches 31 and 32 whose spacing distance corresponds to the thickness that is intended to give to the wall to build. The low spacer 3 is secured to a screw jack 33, 30 itself integral with a sole 34, so as to adjust the height of the positioning of the lower spacer 3 relative to the ground. The connecting element 4 consists of a concrete iron 40 which has a rectilinear segment 41 extending between the two spacers 2 and 3, and which is welded at one end to the lower spacer 3, while its other end has hooking means, in this case a loop 42, for securing it to a clamping device 5 integral with the high spacer 2. The clamping device 5 comprises a threaded rod 50 which freely passes through the high spacer 2 from top to bottom whose end disposed on the side of the notches 21 and 22 is provided with a hook 51 intended to cooperate with the loop 42, while a nut 52 is screwed onto the threaded rod 50 on the other side of the high spacer 2. It will be understood that depending on whether the nut 52 is screwed or unscrewed, the hook 51 moves towards or away from the high spacer 2. It will be noted that the concrete iron 40 comprises , as an extension of rectilinear segment 41, at its secured to the lower spacer 3, an angled segment 43 itself extended by a straight portion 44 which extends transversely, substantially parallel to the longitudinal axis of the low spacer 3. Referring now to Figure 2, we can see two panels 6 and 7, respectively inner and outer, maintained vertically and parallel by means of two fastening devices 1 according to the invention. The inner wall 6 rests in the notches 31, only one of which is visible, the two low spacers 3, while the outer wall 7 rests in the notches 32 of the same low spacers. Each of the lower spacers 3 rests on the ground via a sole 34, and at the chosen height, which is obtained through the screw jack 33. The inner 6 and outer 7 are also maintained higher by the spacers 2, through the notches 21 and 22, and under the action of the clamping device 5. By tightening the nut 52, which in this case is provided with blades 53 handling, against the high spacer 2, it causes the rise of the threaded rod 50, and thus a traction on the concrete bar 40, thereby immobilizing the dams 6 and 7 between the spacers 2 and 3.

Cette opération est réalisée pour chacun des dispositifs 1, et pour toute la construction. On notera que les banches extérieures 7 sont équipées d'étais d'aplomb réglable 8 permettant d'en garantir la verticalité, ces étais 8 comprennent à une extrémité une rotule 80 de fixation à la banche 7, et à l'autre extrémité un pieu d'ancrage 81. En référence maintenant à la figure 3, on peut voir un coffrage réalisé avec un dispositif 1 selon l'invention, lors de la réalisation d'un bassin, de piscine notamment, en une seule coulée. Le coffrage est réalisé par assemblage de banches 6 et 7 à des dispositifs 1, dans une fosse 9 pratiquée dans le sol S. Après mise en place des banches 6 et 7, et assuré leur verticalité au moyen d'étais d'aplomb 8, on coule du béton dans le fond 90 de la fosse 9, sur une épaisseur correspondant à la hauteur sous les banches 6 et 7, jusqu'à noyer entièrement les entretoises basses 3, pour former le radier 91. Puis ceci fait, on coule du béton entre les banches 6 et 7 pour former la paroi 92. This operation is performed for each of the devices 1, and for the entire construction. It will be noted that the outer panels 7 are equipped with adjustable struts 8 to ensure verticality, these struts 8 comprise at one end a ball 80 for fastening to the board 7, and at the other end a pile Anchoring 81. Referring now to Figure 3, we can see a formwork made with a device 1 according to the invention, during the realization of a pool, including pool, in a single casting. The formwork is made by assembling sections 6 and 7 to devices 1, in a pit 9 made in the ground S. After placing the panels 6 and 7, and ensured their verticality by means of struts 8, concrete is poured into the bottom 90 of the pit 9, to a thickness corresponding to the height under the ribs 6 and 7, until completely drowning the low spacers 3, to form the raft 91. Then this is done, it flows concrete between the panels 6 and 7 to form the wall 92.

On notera que le fer à béton 40 n'est pas seul à former l'armature de la structure, et que d'autres fers, non représentés, sont disposés préalablement à la coulée, sur le fond 90 de la fosse 9 et entre les banches 6 et 7. Note that the concrete iron 40 is not only to form the frame of the structure, and that other irons, not shown, are disposed prior to casting on the bottom 90 of the pit 9 and between the 6 and 7.
