Description

L'invention se rattache au secteur technique de la construction et en particulier celui relatif à la couverture de sol par des dalles en béton pouvant inclure des joints de dilatation entre les dalles.The invention relates to the technical sector of construction and in particular that relating to the ground cover by concrete slabs which may include expansion joints between the slabs.

Les dispositifs de coffrage pour dalles de béton sont connus en soi et sont fabriqués par de nombreux constructeurs. Ces dispositifs sont généralement agencés avec des plaques profilées en "L" disposées en opposition, leurs ailes venant côte à côte, et étant jointives à l'aide de moyens spécifiques de liaison. Ces plaques présentent sur leur base et en alternance des formes en découpes et en saillies horizontales dans une configuration complémentaire pour venir s'emboîter et permettre l'encastrement des formes identiques disposées sur chacune des parties planes des plaques précitées.Formwork devices for concrete slabs are known per se and are manufactured by many manufacturers. These devices are generally arranged with "L" profiled plates arranged in opposition, their wings coming side by side, and being joined by means of specific connection means. These plates have on their base alternating shapes in cutouts and horizontal projections in a complementary configuration to fit and allow embedding identical shapes disposed on each of the flat portions of the aforementioned plates.

Ces plaques sont également agencées de manière connue avec des tiges disposées à partir des bases horizontales des plaques et à partir de leurs parois verticales en constituant des moyens de prise du béton.These plates are also arranged in known manner with rods arranged from the horizontal bases of the plates and from their vertical walls by constituting means for setting the concrete.

Ces plaques sont liées entre elles par des moyens de boulonnage et peuvent être écartées horizontalement l'une de l'autre pour tenir compte du retrait du béton en phase de solidification et des variations de température extérieure. L'espace entre les plaques permet le positionnement de joints de dilatation.These plates are interconnected by bolting means and can be spaced horizontally from each other to take into account the shrinkage of concrete in the solidification phase and external temperature variations. The space between the plates allows the positioning of expansion joints.

Une telle disposition se trouve notamment décrite dans le brevet EP 1 391 556 . On connaît aussi par le brevet EP 1 389 648 des appareils de même type pour le coffrage de dalles de béton intégrant à mi-hauteur sensiblement des plaques, des manchons ou inserts horizontaux de liaison entre les blocs des dalles de béton en regard.Such a provision is particularly described in the patent EP 1 391 556 . Also known by the patent EP 1 389 648 appliances of the same type for the formwork of concrete slabs integrating at half height substantially horizontal plates, sleeves or inserts connecting the blocks of concrete slabs facing each other.

Ainsi, le brevet EP 1 389 648 divulgue un dispositif mettant en oeuvre l'utilisation de manchons (17) transversaux pénétrant dans le béton et aussi avec des moyens de relevage (25) (26) fixés à des pièces (14). La conception de ce dispositif ne permet aucun ajustement en inclinaison sur de grandes longueurs. En outre, il n'y a aucune étanchéité au passage du béton en situation d'élévation.Thus, the patent EP 1 389 648 discloses a device implementing the use of transverse sleeves (17) penetrating into the concrete and also with lifting means (25) (26) attached to parts (14). The design of this device does not allow any adjustment in inclination over long lengths. In addition, there is no sealing at the passage of the concrete in elevation situation.

Par ailleurs, le brevet EP 1 391 556 relève d'une construction sans aucune capacité de réglage en hauteur en fonction de l'épaisseur de la couche de béton coulée.Moreover, the patent EP 1 391 556 is a construction without any capacity for height adjustment depending on the thickness of the cast concrete layer.

De plus, on connaît par le document DE 20 2009000007 une solution de variation en hauteur d'une plaque.Moreover, we know from the document DE 20 2009000007 a solution for varying the height of a plate.

La problématique est la suivante :The problem is the following:

Les dispositifs de coffrage pour dalles de béton ainsi connus sont établis et conçus pour constituer des modules standards de dimensions préétablies et notamment de dimensions verticales définies selon une hauteur correspondant à une épaisseur de dallage standardisée. Cela implique donc pour les opérateurs et poseurs de pouvoir disposer d'une gamme de dispositifs de coffrage de dimensions variables. A la connaissance du Demandeur, cette pratique est généralisée et ne semble pas présenter de contraintes spécifiques pour les opérateurs. A la connaissance du Demandeur, aucun fabricant de ce type de matériel, bien que la technologie soit très ancienne, ne s'est penché réellement sur cette pratique.The formwork devices for known concrete slabs are established and designed to constitute standard modules of pre-established dimensions and in particular of vertical dimensions defined according to a height corresponding to a standardized pavement thickness. This implies for operators and installers to have a range of formwork devices of varying sizes. To the knowledge of the Applicant, this practice is generalized and does not seem to present specific constraints for operators. To the knowledge of the Applicant, no manufacturer of this type of equipment, although the technology is very old, has really considered this practice.

La raison en est peut-être, outre l'absence de besoins, il y avait une difficulté à résoudre pour concevoir et réaliser un même dispositif de coffrage pouvant être modifié dans l'une de ces dimensions caractéristiques et en particulier, celle de la hauteur.The reason is perhaps, besides the absence of needs, there was a difficulty to solve to conceive and realize the same device of formwork that can be modified in one of these characteristic dimensions and in particular, that of the height.

Le Demandeur s'est donc intéressé à cette problématique et après de nombreuses recherches et essais, une solution originale a été mise en oeuvre par ce dernier. La solution est simple, pratique, peu coûteuse à mettre en oeuvre et permet une variation de hauteur du dispositif de coffrage sur une distance substantielle de plusieurs centimètres tenant compte alors des possibles variations d'épaisseur des dalles de béton en fonction des besoins de la construction.The Applicant was therefore interested in this problem and after many researches and tests, an original solution was implemented by the latter. The solution is simple, practical, inexpensive to implement and allows a variation in height of the formwork device over a substantial distance of several centimeters taking into account possible variations in thickness of the concrete slabs depending on the needs of the construction .

Selon une première caractéristique de l'invention, le dispositif de réglage de la hauteur d'un coffrage de dalles de béton, du type comprenant une première et une seconde base support horizontale profilée et agencée en présentant une pluralité de formes en saillies et de découpes susceptibles de s'enchevêtrer par encastrement, les dites bases supports recevant des tiges constituant des prises de béton, le dispositif étant remarquable en ce que la première base support horizontale reçoit à fixation des premiers couples d'équerres aménagés et espacés présentant une branche verticale autorisant la fixation réglable en hauteur d'une plaque verticale constitutive d'un système de rehausse, et en ce que la dite seconde base support est agencée avec des seconds couples d'équerres disposés en opposition des dits premiers couples d'équerres en étant disposés fixes sur la dite seconde base support, et en ce que les dits seconds couples d'équerres par leur branche verticale autorisent la fixation d'une contreplaque verticale à position fixe, et en ce que la plaque est agencée sur sa longueur avec des lumières oblongues établies sur une partie de sa hauteur, et en ce que la contreplaque présente des ouvertures pour l'intégration d'un moyen sous forme de boulonnage permettant le réglage et la fixation de la plaque par rapport à la contreplaque, et en ce que les couples d'équerres (sont agencés avec des ouvertures pour le passage des moyens de liaison et de réglage en position et en ce que la dite plaque présente en sa partie supérieure un plan d'appui horizontal recevant un bloc recevant des prises de béton, et en ce que le dit plan d'appui est établi sur une partie de la largeur du dit bloc en laissant libre une zone d'appui d'un moyen élévateur.According to a first characteristic of the invention, the device for adjusting the height of a concrete slab formwork, of the type comprising a first and a second shaped horizontal support base and arranged with a plurality of projecting shapes and cutouts. which are capable of becoming entangled by embedding, the said support bases receiving rods constituting concrete plugs, the device being remarkable in that the first horizontal support base receives the first pairs of brackets arranged and spaced apart having a vertical branch allowing the height-adjustable fixing of a vertical plate constituting a raising system, and in that said second support base is arranged with second pairs of brackets arranged in opposition of said first pairs of brackets being arranged fixed on said second base support, and in that said second pairs of squares by their worm branch make it possible to fix a vertical counterplate with a fixed position, and in that the plate is arranged along its length with oblong slots set over part of its height, and in that the counterplate has openings for the integration of bolting means for adjusting and fixing the plate relative to the counterplate, and in that the pairs of brackets (are arranged with openings for the passage of the connecting means and adjustment in position and in that said plate has in its upper part a horizontal support plane receiving a block receiving concrete plugs, and in that the said support plane is established on a part of the width of said block leaving free a support zone of a lifting means.

Selon une autre caractéristique, la dite plaque présente en sa partie supérieure un plan d'appui horizontal recevant un bloc récepteur recevant des prises de béton, et en ce que le dit plan d'appui est établi sur une partie de la largeur du dit bloc en laissant libre une zone d'appui d'un moyen élévateur, et en ce que la réhausse de la plaque s'effectue par un moyen élévateur comprenant une plateforme d'appui sur la ou les bases de la dite plaque et un mât récepteur d'un moyen de commande en élévation ou abaissement d'un bras support susceptible de coopérer avec le bloc disposé en bout de la plaque.According to another characteristic, said plate has in its upper part a horizontal support plane receiving a receiving block receiving concrete plugs, and in that said support plane is established on part of the width of said block leaving free a support zone of a lifting means, and in that the raising of the plate is effected by a lifting means comprising a support platform on the base or bases of said plate and a receiving mast d control means in elevation or lowering of a support arm capable of cooperating with the block disposed at the end of the plate.

Ces caractéristiques et bien d'autres encore ressortiront bien de la suite de la description.These characteristics and many others will be apparent from the rest of the description.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustré aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

Le dispositif de coffrage de dalles de béton avec joints de dilatation est référencé par (D). Il comprend sur une grande longueur deux bases supports (1) (2) horizontales profilées et agencées chacune avec une pluralité de formes en saillies (1a) (2a) et de découpes (1b) (2b) susceptibles de s'enchevêtrer par encastrement. Ces bases supports sont notamment illustrées aux figures 1 et 2. Elles reçoivent de manière connue des tiges (3) disposées en oblique et constituant des prises de béton.The formwork device for concrete slabs with expansion joints is referenced by (D). It comprises a large length two support bases (1) (2) profiled horizontal and each arranged with a plurality of projecting shapes (1a) (2a) and cutouts (1b) (2b) capable of entangling by embedding. These support bases are illustrated in particular in figures 1 and 2 . They receive in known manner rods (3) arranged obliquely and constants of concrete.

Selon l'invention, la première base support (1) horizontale reçoit sur sa face apparente une pluralité de premiers couples d'équerres (4a) (4b) espacées selon la longueur de la base support (1). Les équerres (4a) (4b) d'un même couple sont espacées l'une de l'autres sensiblement. Le nombre de couples d'équerres (4a) (4b) dépend de la longueur du coffrage. Leur fixation à la base support (1) s'effectue par soudure ou autrement. A partir de leur branche verticale, les couples d'équerres permettent la fixation d'une plaque verticale (5) métallique, réalisée en tôle ou autrement. Chaque équerre (4a) (4b) présente une ouverture (4c) pour l'insertion d'un boulonnage (6) ainsi que préciser par la suite. La plaque verticale (5) est ainsi aménagée avec une pluralité de lumières oblongues (5a), verticales, en nombre correspondant au nombre de couples d'équerres (4a) (4b) précités. La partie supérieure de la plaque (5) est agencée pour recevoir un moyen (7) permettant sa réhausse ainsi qu'il sera précisé par la suite. La seconde base support (2) est également agencée pour la réception de seconds couples d'équerres (8a) (8b) destinés à être en opposition des dits premiers couples d'équerres (4a) (4b). Par leur branche verticale, le second couple d'équerres autorise la fixation d'une contreplaque (9) verticale, métallique, en tôle par exemple. Les seconds couples d'équerres (8a) (8b) et la contreplaque (9) sont également agencés avec des ouvertures (8c) (9a) circulaires pour le passage et introduction des moyens de boulonnage (6) et de blocage précités.According to the invention, the first horizontal support base (1) receives on its apparent face a plurality of first pairs of brackets (4a) (4b) spaced along the length of the support base (1). The brackets (4a) (4b) of the same pair are spaced apart from each other substantially. The number of pairs of brackets (4a) (4b) depends on the length of the formwork. They are attached to the support base (1) by welding or otherwise. From their vertical branch, the pairs of brackets allow the attachment of a vertical plate (5) metal, made of sheet metal or otherwise. Each square (4a) (4b) has an opening (4c) for the insertion of a bolting (6) and specify thereafter. The vertical plate (5) is thus arranged with a plurality of oblong slots (5a), vertical, in number corresponding to the number of pairs of brackets (4a) (4b) above. The upper part of the plate (5) is arranged to receive a means (7) for its enhancement as will be specified later. The second support base (2) is also arranged for receiving second pairs of brackets (8a) (8b) intended to be in opposition to said first pairs of brackets (4a) (4b). By their vertical branch, the second pair of brackets allows the attachment of a counter plate (9) vertical, metal, sheet metal for example. The second pairs of brackets (8a) (8b) and the counterplate (9) are also arranged with circular openings (8c) (9a) for the passage and introduction of bolting means (6) and aforementioned locking.

Dans la mise en oeuvre illustrée figure 12, les équerres (4a)(4b) et le cas échéant (8a) (8b) sont reliées entre elles en partie supérieure par un bras de liaison horizontal (4d), le bras relatif aux équerres (8a) (8b) n'étant pas représenté. Cela permet une simplification de montage et de réglage des équerres. L'ouverture (4c) est alors disposée sur le bras (4d) correspondant. Il en est de même pour les autres couples d'équerres. Ces ouvertures servent au passage du boulonnage.In the illustrated implementation figure 12 the brackets (4a) (4b) and, where appropriate, (8a) (8b) are interconnected at the top by a horizontal connecting arm (4d), the arm relative to the brackets (8a) (8b) being not represented. This allows a simplification of assembly and adjustment of the brackets. The opening (4c) is then arranged on the corresponding arm (4d). It is the same for other pairs of brackets. These openings serve for the passage of bolting.

Ainsi selon l'invention, la plaque (5) va pouvoir être réglée en position verticale en hauteur par rapport à la contreplaque (9) qui elle est fixe. Le réglage en hauteur en fonction des besoins s'effectue par le biais des différentes lumières oblongues (5a) qui permettent ainsi le passage des boulonnages (6). La longueur des lumières oblongues définit donc la hauteur de réglage possible entre la plaque (5) et la contreplaque (9). La dimension de la plaque (5) est donc établie par rapport à la hauteur de la contreplaque (9). Ainsi, en fonction des besoins, la plaque (5) peut-être positionnée à une hauteur à l'horizontale constante par rapport à la contreplaque, ou en inclinaison selon une légère angulation qui est autorisée justement par les dites lumières.Thus according to the invention, the plate (5) can be adjusted vertically in height relative to the counter plate (9) which is fixed. The adjustment in height according to the needs is carried out by means of the various oblong slots (5a) which thus allow the passage of the bolting (6). The length of the oblong slots thus defines the possible height of adjustment between the plate (5) and the counterplate (9). The dimension of the plate (5) is therefore established relative to the height of the counterplate (9). Thus, depending on the needs, the plate (5) can be positioned at a constant horizontal height relative to the counter plate, or in inclination according to a slight angulation which is authorized precisely by said lights.

Dans sa partie supérieure, cette plaque (5) présente un plan d'appui (5b) horizontal sur lequel est disposé et fixé par tous moyens appropriés un bloc parallépipédique (10) recevant de part et d'autre de son plan longitudinal des tiges (11) constituant des prises de béton, ainsi disposées pour assurer un équilibrage. Avantageusement, le plan d'appui (5b) est établi sur une partie seulement de la largeur du bloc (11) en laissant libre pour celui-ci une zone (11a) d'appui du moyen élévateur.In its upper part, this plate (5) has a horizontal support plane (5b) on which is arranged and fixed by any appropriate means a parallelepiped block (10) receiving on either side of its longitudinal plane of the rods ( 11) constituting concrete plugs, thus arranged to ensure a balancing. Advantageously, the support plane (5b) is established on only a part of the width of the block (11) leaving free for it a zone (11a) of support of the elevator means.

Le moyen d'élévation, notamment représenté aux figures 9 à 12 comprend une plateforme (12) horizontale pouvant être fixée au sol et pouvant prendre appui par une extrémité (12a) sur la base support horizontale (1). Cette plateforme reçoit un mât vertical (13) susceptible d'être agencé avec un dispositif à crémaillère ou similaire commandé par manivelle (14) et permettant l'élévation ou l'abaissement d'un bras (15) présentant en bout un bloc d'appui (16) et de soulèvement. Ce bras est susceptible d'être déplacé en hauteur sous l'action de la manivelle de toute manière connue de l'Homme de l'Art. Le bloc d'appui (16) est susceptible de venir en contact inférieur avec la base du bloc (10) récepteur du joint de dilatation. Après desserrage des moyens de réglages (6), il est ainsi possible, par l'opérateur de provoquer le relevage ou l'abaissement de la rehausse ce qui entraîne le déplacement vertical de la plaque (5) par rapport à la contreplaque (9) en augmentant la hauteur du dispositif de coffrage ainsi constitué. La manipulation de ce réglage en hauteur peut s'effectuer selon la dimension du dispositif de coffrage avec ou plusieurs moyens permettant la rehausse et régulièrement disposés et espacés par rapport à la longueur du dispositif de coffrage.The elevation means, in particular represented Figures 9 to 12 comprises a platform (12) horizontal can be fixed to the ground and can bear at one end (12a) on the horizontal support base (1). This platform receives a vertical mast (13) capable of being arranged with a rack-and-pinion-like device (14) and allowing the raising or lowering of an arm (15) having at the end a bearing block (16) and lifting. This arm is likely to be moved in height under the action of the crank in any manner known to those skilled in the art. The bearing block (16) is able to come into lower contact with the base of the expansion joint receiver block (10). After loosening the adjustment means (6), it is thus possible, by the operator to cause raising or lowering of the raiser which causes the vertical displacement of the plate (5) relative to the counter plate (9) by increasing the height of the formwork device thus formed. Manipulation of this height adjustment can be performed according to the size of the formwork device with or several means for raising and regularly arranged and spaced relative to the length of the formwork device.

En variante de réalisation, et en fonction des plaques (5) et contreplaque (9), on pourrait concevoir sans modification de la portée de l'invention que le réglage à hauteur de la plaque (5) s'effectue uniquement manuellement.As an alternative embodiment, and as a function of the plates (5) and counterplate (9), it could be conceived without modification of the scope of the invention that the height adjustment of the plate (5) is performed manually only.

Le moyen élévateur de la rehausse peut être agencé intérieurement avec une chaîne sans fin ou tout autre moyen équivalent qui serait associé au bras (15) récepteur du bloc d'appui (16). Sans sortir du cadre de l'invention, le bras porteur (15) peut aussi être agencé avec un autre moyen équivalent au bloc (16) pour permettre le soulèvement de la rehausse.The lifting means of the riser can be arranged internally with an endless chain or any other equivalent means that would be associated with the arm (15) receiving the support block (16). Without departing from the scope of the invention, the support arm (15) can also be arranged with another equivalent means to the block (16) to allow the raising of the riser.

On se réfère maintenant à la mise en oeuvre optimisée du moyen élévateur de la rehausse représentée figures 13 à 15. La plateforme d'appui (12) reçoit un mat récepteur (13) qui dans sa partie supérieure comprend le moyen de commande (14) en élévation ou abaissement, selon la flèche F1 du bras support (15) de la rehausse. Dans cette mise en oeuvre, le bras (15) est aménagé pour permettre un léger déplacement horizontal en avant ou en arrière selon la flèche F2 par un moyen (17) du type à vis. L'extrémité avant du bras support comprend une plaque d'appui (18) susceptible de venir en appui contre la plaque (5) et plus spécifiquement sur le plan d'appui (5b) associé à la rehausse. En se référant aux figures 14 et 15, une mise en oeuvre optimisée consiste à prévoir un agencement du bras porteur (15) avec un cadre intérieur horizontal (15a) à position fixe par rapport au mât (13) en ayant une configuration en U. Un cadre extérieur (15b) horizontal en U est disposé autour du cadre intérieur précité en étant guidé et maintenu par rapport à celui-ci, à l'aide de moyens de liaison (20) de tout type connu. Le cadre extérieur présente dans sa partie de fond de son profil en U une ouverture taraudé permettant le passage de la vis de manoeuvre (17). La partie mât présente une portée (13a) aménagée avec un alésage intérieur permettant la liaison avec la vis (17). Le cadre extérieur (15b) présente dans sa partie avant une plateforme débordante (15c) horizontale sur laquelle est disposé un bloc parallélépipédique formant tasseau (21) disposé perpendiculairement par rapport à l'axe longitudinal du cadre. La largeur de ce tasseau est inférieur à la largeur de la plateforme de façon à laisser apparaître une partie (15d) débordante qui sera susceptible de venir en appui sur la partie (5b) associée à la rehausse. Le bloc (21) est monté avec une capacité de pivotement angulaire de quelques degrés par un moyen de liaison (15.e) solidaires de la plateforme (15c). Cela permet une orientation dudit bloc qui vient en appui contre la plaque (5), et permet ainsi d'améliorer la rigidité de l'ensemble du dispositif une fois monté et éviter tout effet de déformation ondulaire sur de grandes longueurs.We now refer to the optimized implementation of the elevating means of the riser shown Figures 13 to 15 . The support platform (12) receives a receiving mat (13) which in its upper part comprises the control means (14) in elevation or lowering, according to the arrow F1 of the support arm (15) of the riser. In this implementation, the arm (15) is arranged to allow a slight horizontal displacement forward or rear according to the arrow F2 by a means (17) of the screw type. The front end of the support arm comprises a support plate (18) capable of bearing against the plate (5) and more specifically on the support plane (5b) associated with the riser. Referring to figures 14 and 15 , an optimized implementation consists in providing an arrangement of the support arm (15) with a horizontal inner frame (15a) fixed position relative to the mast (13) having a U-shaped configuration. A horizontal outer frame (15b) in U is disposed around the aforesaid inner frame being guided and maintained relative thereto, using connecting means (20) of any known type. The outer frame has in its bottom portion of its U-profile a threaded opening for the passage of the actuating screw (17). The mast portion has a bearing (13a) arranged with an internal bore for connection with the screw (17). The outer frame (15b) has in its front part a horizontal projecting platform (15c) on which is disposed a parallelepiped block forming a batten (21) arranged perpendicular to the longitudinal axis of the frame. The width of this cleat is less than the width of the platform so as to reveal a portion (15d) overflowing which will be likely to bear on the portion (5b) associated with the riser. The block (21) is mounted with an angular pivoting capacity of a few degrees by a connecting means (15.e) integral with the platform (15c). This allows an orientation of said block which abuts against the plate (5), and thus improves the rigidity of the entire device once mounted and avoid any wave deformation effect over long lengths.

On se réfère maintenant aux figures 16 à 18 qui illustrent la mise en oeuvre d'un moyen complémentaire garantissant la stabilisation du dispositif en cas d'effet de poussée du béton. Ce moyen (22) est constitué pour chaque ensemble de bases supports (1) (2) par une plaque de stabilisation disposée transversalement par rapport au dispositif. Ces plaques de stabilisation (22) de grande longueur débordent de part et d'autre des bases supports (1) et (2). Elles comprennent en extrémités une ouverture circulaire (22.1) pour le positionnement d'un clou de fixation, non représenté, puis une lumière oblongue (22.2) de configuration rectangulaire susceptibles de recevoir en position une bride de serrage (23) qui est maintenue par rapport à ladite plaque par un moyen de fixation (24), à travers une lumière (23.1). Comme représenté aux dessins, les brides de serrage (23) viennent en position sur les bases supports pour assurer leur tenue et positionnement. Cela permet d'absorber les efforts de poussée dus au béton coulé.We now refer to Figures 16 to 18 which illustrate the implementation of a complementary means ensuring the stabilization of the device in case of concrete thrust effect. This means (22) is constituted for each set of support bases (1) (2) by a stabilization plate disposed transversely relative to the device. These plates stabilization (22) of great length overflow on both sides support bases (1) and (2). They comprise at the ends a circular opening (22.1) for the positioning of a fastening nail, not shown, then an oblong slot (22.2) of rectangular configuration capable of receiving in position a clamping flange (23) which is held in relation to to said plate by a fixing means (24), through a light (23.1). As shown in the drawings, the clamps (23) are in position on the support bases to ensure their holding and positioning. This makes it possible to absorb the thrust forces due to poured concrete.

Les avantages ressortent bien de l'invention. On souligne la simplicité du dispositif de rehausse, du dispositif de coffrage selon les besoins. Il permet un réglage affiné tenant compte aussi des variations d'horizontalité du sol et une légère amplitude d'inclinaison selon les besoins.The advantages are apparent from the invention. It emphasizes the simplicity of the raising device, the formwork device as needed. It allows a refined adjustment taking into account also variations of horizontality of the ground and a slight amplitude of inclination according to the needs.

Le dispositif est simple à mettre en oeuvre. L'amplitude de surélévation de la plaque (5) par rapport à la contreplaque (9) peut être de plusieurs centimètres ce qui donne ainsi de larges possibilités d'utiliser le dispositif pour des épaisseurs de dalles de béton variables.The device is simple to implement. The amplitude of elevation of the plate (5) relative to the counterplate (9) can be several centimeters, which thus gives wide possibilities of using the device for varying thicknesses of concrete slabs.
