Description

Lorsqu'il s'agit de couler des dalles de béton directement sur le sol, on procède par bandes successives en utilisant en guise de coffrage des banches de bois que l'on cloue sur des piquets plantés dans le sol. Le sol étant irrégulier et le mode de fixation des banches sur les piquets assez grossier, il est difficile d'obtenir des dalles parfaitement horizontales. En outre, la mise en place des éléments de coffrage est relativement longue et le matériel utilisé n'a pas une durée de vie très longue vu que la pose et l'enlèvement successifs de clous détériore les banches.When it comes to pouring concrete slabs directly on the ground, we proceed in successive strips using as formwork wooden boards that are nailed on stakes planted in the ground. The ground being irregular and the method of fixing the formwork to the stakes quite coarse, it is difficult to obtain perfectly horizontal slabs. In addition, the installation of the formwork elements is relatively long and the material used does not have a very long service life since the successive installation and removal of nails deteriorates the formwork.

Les brevets USA Nos 2.281.946 et 4.066.237 et CH No 255.652 montrent de tels appareillages destinés à être ancrés dans le sol. Dans le brevet USA 2.014.826, il est décrit un appareillage qui ne nécessite pas d'ancrage et qui se pose directement sur le sol, mais il ne permet pas de couler des dalles de béton précises, car il est dépourvu de moyens de réglage permettant de compenser les inévitables inégalités locales de niveau du sol, lorsque celui-ci n'a pas été préalablement nivelé de façon précise.US Patents Nos. 2,281,946 and 4,066,237 and CH No 255,652 show such apparatus intended to be anchored in the ground. In the patent US 2,014,826, an apparatus is described which does not require anchoring and which is posed directly on the ground, but it does not make it possible to pour precise concrete slabs, because it is devoid of adjustment means allowing to compensate for the inevitable local inequalities of level of the ground, when this one was not previously leveled in a precise way.

La présente invention vise à fournir un appareillage de coffrage permettant de couler directement sur le sol des dalles de béton précises, c'est-à-dire parfaitement horizontales en procédant par bandes successives, sans nécessité d'aucun ancrage dans le sol.The present invention aims to provide a formwork apparatus for pouring concrete concrete slabs directly onto the ground, that is to say perfectly horizontal, proceeding in successive strips, without the need for any anchoring in the ground.

Cet appareillage se distingue des systèmes connus par le fait qu'il comporte des supports de préférence métalliques prévus pour reposer sur le sol et pour supporter de façon amovible des banches métalliques. Ces supports sont munis de moyens de réglage en hauteur des banches. Cet appareillage comprend en outre des entretoises amovibles pour fixer l'écartement de deux banches parallèles servant à couler une bande de béton, des fils de tension destinés à être tendus entre les banches en les traversant et des moyens pour tendre ces fils et les immobiliser par rapport aux banches.This apparatus is distinguished from known systems by the fact that it comprises preferably metal supports intended to rest on the ground and to removably support metal formwork. These supports are provided with means for adjusting the height of the forms. This apparatus further comprises removable spacers for fixing the spacing of two parallel formwork serving to pour a strip of concrete, tension wires intended to be stretched between the formwork while crossing them and means for tensioning these wires and immobilizing them by compared to the formwork.

Le dessin annexé représente à titre d'exemple une forme d'exécution de l'appareillage objet de l'invention.

L'appareillage représenté comprend des supports métalliques 1 que l'on dispose sur le sol après avoir nivelé celui-ci et fixé l'alignement au moyen de cordeaux. L'appareillage comprend des banches 2 que l'on met en place dans l'alignement des cordeaux en les faisant reposer, comme on le verra plus loin, sur une partie des supports 1.The apparatus shown comprises metal supports 1 which are placed on the ground after having leveled the latter and fixed the alignment by means of cords. The apparatus comprises panels 2 which are placed in alignment with the cords by making them rest, as will be seen below, on a part of the supports 1.

En se référant à la figure 2, on voit que chaque support 1 est formé d'une base constituée par une croix de profilés en U. Au centre de cette croix il est prévu en 3 un bossage dans lequel est engagée l'esquisse inférieure d'une vis 4 présentant deux plats 5 (figures 3 et 4) de sorte que la vis soit maintenue verticale c'est-à-dire perpendiculaire à la base et soit empêchée de tourner sur elle-même. Cette vis est solidaire d'un disque 6 présentant des encoches périphériques 7 et qui sert à faire'tourner la vis au moyen d'une clé 8 fourchue.Referring to Figure 2, we see that each support 1 is formed of a base formed by a cross of U-shaped profiles. At the center of this cross is provided at 3 a boss in which is engaged the lower sketch d 'A screw 4 having two dishes 5 (Figures 3 and 4) so that the screw is kept vertical that is to say perpendicular to the base and is prevented from turning on itself. This screw is integral with a disc 6 having peripheral notches 7 and which is used to rotate the screw by means of a forked wrench 8.

Sur cette vis est engagé un écrou 9 solidaire d'une pièce d'appui 10 en forme de cornière dont une aile 11 est verticale et l'autre, 12, est horizontale.On this screw is engaged a nut 9 secured to a support piece 10 in the form of an angle iron, one wing 11 of which is vertical and the other, 12, of which is horizontal.

Les banches 2 présentent à leur partie supérieure un rebord 13 perpendiculaire au plan principal de la banche. C'est par ce rebord que ces banches viennent reposer sur la partie 12 des pièces d'appui 10 tandis que le corps principal des banches vient s'appliquer contre l'aile verticale 11 de ces pièces d'appui.The forms 2 have at their upper part a rim 13 perpendicular to the main plane of the form. It is by this rim that these forms come to rest on the part 12 of the support pieces 10 while the main body of the forms comes to rest against the vertical wing 11 of these support pieces.

Ces supports 1 sont disposés à l'endroit où deux banches successives sont en contact et il est prévu sur la face inférieure du rebord 13 des tétons 14 destinés à s'engager dans des trous correspondants 15 de l'aile 12, pour assurer le positionnement longitudinal correct des banches successives 2. Le positionnement vertical correct des banches se fait en tournant chacune des vis 4 de manière à amener le bord supérieur des banches selon des lignes horizontales situées dans le plan de la face supérieure de la dalle de béton qu'il s'agit de former. Ce réglage peut être fait avec toute la précision désirable pour un tel travail.These supports 1 are arranged at the place where two successive forms are in contact and there are provided on the underside of the rim 13 studs 14 intended to engage in corresponding holes 15 of the wing 12, to ensure the position correct longitudinal alignment of the successive forms 2. The correct vertical positioning of the forms is done by turning each of the screws 4 so as to bring the upper edge of the forms along horizontal lines located in the plane of the upper face of the concrete slab that it's about training. This adjustment can be made with any precision desired for such work.

Lorsque les banches sont ainsi amenées sur les pièces 10 des supports 1, on dispose entre les deux rangées de banches des entretoises 16 assurant l'écartement correct de ces banches. Pour assurer que ces banches n'aient pas tendance à faire pression horizontalement sur les supports 1, ce qui risquerait de les déplacer et de détruire l'alignement correct des banches, lorsque l'on coule le béton, il est prévu des fils métalliques de tension 17 que l'on fait traverser des trous 18 (un seul est visible sur la figure 2) pratiqués dans les banches. A l'une de leurs extrémités ces fils 17 sont recourbés à angle droit et s'appliquent contre la face extérieure vertirale d'une des banches. L'autre extrémité, visible en 19, est engagée dans une pièce de retenue 20 prévue pour recevoir un coin métallique 21. Au moyen d'un outil de type connu on vient agir sur la partie terminale 22 du fil 17 pour exercer une tension sur ce fil et l'on chasse le coin 21 dans la pièce 20 de manière à coincer dans celle-ci le fil 17 et l'obliger par conséquent à rester sous tension. Les fils 17 sont espacés régulièrement et les entretoises 16 sont placées juste à la verticale de ces fils. Ainsi les deux banches parallèles sont maintenues fortement dans leur position correcte et ne subissent pas de déplacements ni de déformations sensibles lorsque l'on coule le béton, comme indiqué en 23.When the forms are thus brought to the parts 10 of the supports 1, spacers 16 are provided between the two rows of forms ensuring the correct spacing of these forms. To ensure that these forms do not tend to put pressure horizontally on the supports 1, which would risk displacing them and destroying the correct alignment of the forms, when pouring the concrete, metallic wires are provided. tension 17 which is passed through holes 18 (only one is visible in Figure 2) made in the formwork. At one of their ends, these wires 17 are bent at a right angle and are applied against the vertical external face of one of the forms. The other end, visible at 19, is engaged in a retaining piece 20 designed to receive a metal wedge 21. By means of a tool of known type, the end portion 22 of the wire 17 is acted upon to exert tension on this wire and chasing the corner 21 in the part 20 so as to wedge therein the wire 17 and therefore force it to remain energized. The wires 17 are spaced regularly and the spacers 16 are placed just vertical to these wires. Thus the two parallel formwork are held firmly in their correct position and do not undergo significant displacements or deformations when pouring the concrete, as indicated in 23.

On remarquera que les supports 1 sont placés de manière que l'un seulement des bras , 24, de la base en forme de croix soit engagé sous les banches et partiellement sous le bord de la dalle lorsque la coulée est finie.It will be noted that the supports 1 are placed so that only one of the arms, 24, of the cross-shaped base is engaged under the forms and partially under the edge of the slab when the casting is finished.

La vis 4 présente, comme on le voit sur la figure 3, un filet 25 dont la coupe est sensiblement semi-circulaire. Les spires successives du filet 25 sont séparées par une partie cylindrique 26 relativement grande par rapport à la largeur du filet lui-même. Cette disposition permet de détacher facilement le béton qui pourrait s'être accidentellement déposé sur la vis pendant une opération de coulée et qui aurait durci sur cette vis. Vu la forme du filet et vu l'importance de la partie cylindrique 26 séparant les spires successives, il est facile, comme l'expérience l'a montré, de détacher le béton simplement en donnant un ou deux coups sur la vis au moyen d'un marteau par exemple.The screw 4 has, as seen in Figure 3, a thread 25 whose section is substantially semi-circular. The successive turns of the thread 25 are separated by a cylindrical part 26 relatively large compared to the width of the thread itself. This arrangement makes it possible to easily detach the concrete which could have accidentally deposited on the screw during a casting operation and which would have hardened on this screw. Given the shape of the thread and given the importance of the cylindrical part 26 separating the successive turns, it is easy, as experience has shown, to detach the concrete simply by giving one or two strokes on the screw by means of 'a hammer for example.

Lorsque le béton a été coulé entre les deux banches parallèles visibles sur la figure 1, on nivelle de façon connue la surface supérieure du béton au moyen d'une planche que l'on tient à la main afin que cette face supérieure de la bande de béton soit parfaitement horizontale et affleure avec le bord supérieur des banches. Bien entendu, lors de l'opération de coulée on enlève les entretoises 16 l'une après l'autre lorsqu'on arrive à proximité d'elles. Par contre, les fils de tension 17 restent pris dans le béton. La présence des entretoises n'est en effet plus nécessaire dès l'instant que le béton est coulé, la masse de celui-ci s'opposant à un rapprochement des banches sous l'effet de la tension des fils 17.When the concrete has been poured between the two parallel formwork visible in FIG. 1, the upper surface of the concrete is leveled in a known manner by means of a board which is held in the hand so that this upper face of the strip of concrete is perfectly horizontal and flush with the upper edge of the formwork. Of course, during the casting operation, the spacers 16 are removed one after the other when one comes close to them. On the other hand, the tension wires 17 remain trapped in the concrete. The presence of the spacers is in fact no longer necessary from the moment that the concrete is poured, the mass of the latter opposing a bringing together of the forms under the effect of the tension of the wires 17.

Lorsque le béton a pris, on dégage les coins 21 des pièces 20 et l'on enlève celles-ci. On coupe la partie dépas- sante 19 des fils 17 et dès lors on peut sans difficulté dégager les banches et enlever les supports 1. Lorsque tout l'appareillage a été ainsi démonté, on a une bande de béton et l'on procède de même un peu plus loin en sautant la largeur d'une bande, si bien que l'on a finalement une série de bandes parallèles de béton toutes parfaitement à niveau avec, entre elles, des bandes vides dans lesquelles il ne reste plus qu'à couler du béton, les bandes déjà faites formant coffrage.When the concrete has set, the corners 21 of the parts 20 are released and these are removed. The protruding part 19 of the wires 17 is cut and it is therefore easy to disengage the formwork and remove the supports 1. When all the apparatus has been thus dismantled, there is a strip of concrete and the procedure is the same. a little further by skipping the width of a strip, so that we finally have a series of parallel strips of concrete all perfectly level with, between them, empty strips in which it only remains to sink concrete, the strips already made forming formwork.

L'appareillage décrit peut être utilisé indéfiniment et peut permettre de faire des dalles de n'importe quelles dimensions, en utilisant selon les cas le nombre de banches et de supports nécessaire pour former les bandes de béton successives.The apparatus described can be used indefinitely and can make it possible to make slabs of any size, using as appropriate the number of forms and supports necessary to form the successive strips of concrete.

L'armature 27 du béton peut être mise en place avant les fils de tension 17 ou après ceux-ci, selon la position de cette armature dans le béton. Le réglage en hauteur des banches comme il a été décrit peut être fait très exactement au moyen d'une lunette de chantier ou même simplement d'un niveau d'eau. L'appareillage décrit permet d'exécuter une dalle dont la face supérieure est parfaitement horizontale et auniveau voulu, avec un minimum de temps consacré à la mise en place et à l'enlèvement de cet appareillage.The reinforcement 27 of the concrete can be put in place before the tension wires 17 or after these, depending on the position of this reinforcement in the concrete. The height adjustment of the formwork as it has been described can be done very exactly by means of a site telescope or even simply with a water level. The apparatus described makes it possible to execute a slab the upper face of which is perfectly horizontal and at the desired level, with a minimum of time devoted to the installation and removal of this apparatus.
