Description

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

La présente invention concerne un cadre utilisable pour l'obtention de panneaux de coffrage, ainsi que le verrou à travers lequel est réalisée la liaison entre les cadres pour l'obtention de la surface générale de coffrage, concrètement dans le cas de panneaux destinés à être manipulés manuellement.The present invention relates to a usable frame for obtaining formwork panels, as well as bolt through which the connection between the frames for obtaining the general formwork surface, specifically in the case of panels intended to be handled manually.

Le but de l'invention est d'obtenir un cadre rigide qui permette un montage facile de la plaque constitutive du panneau proprement dit de fixation rapide et efficace pour le reste des cadres ou panneaux qui participent à un coffrage déterminé.The object of the invention is to obtain a rigid frame which allows easy mounting of the constituent plate of the panel itself for fast and efficient fixing for the rest of the frames or panels participating in a determined formwork.

ANTÉCÉDENTS DE L'INVENTIONBACKGROUND OF THE INVENTION

Les panneaux de coffrage manuellement portables tels que dans le document DE-A-31 22 191 sont constitués à partir d'un cadre métallique (1) généralement entretoisé, sur lequel il est établi une planche en bois de dimensions et poids réduits pour permettre son transport et sa manipulation manuel, sans nécessité de grues.Manually portable formwork panels as in document DE-A-31 22 191 are made from a metal frame (1) generally braced, on which a wooden plank of reduced dimensions and weight to allow its transport and its manual handling, without the need for cranes.

Pour réaliser le formage d'un coffrage, l'on dispose différents panneaux de ce genre adossés coplanairement, par l'intermédiaire de moyen de liaison qui généralement consistent à des sangles, clips, etc., ou à l'aide de profilés angulaires intermédiaires lorsque la surface générale de coffrage doit subir un cambrage. To form a formwork, we have different panels of this kind back-to-back, by the intermediary of connecting means which generally consist of straps, clips, etc., or using intermediate angle profiles when the surface formwork must be bent.

Parallèlement, ils sont pourvus de logements pour la mise en place de barres d'écartement, qui permettent d'établir, de façon rapide et simple, la séparation entre les deux parois de coffrage selon l'épaisseur prévue pour le mur à obtenir.At the same time, they are provided with accommodation for installation of spreader bars, which allow establish quickly and easily the separation between the two formwork walls according to the thickness provided for the wall to get.

Généralement ces panneaux dispose également de poignées qui permettent une manipulation commode pour l'opérateur, ainsi que des moyens de support pour la mise en place et le soutien des planches en bois.Generally these panels also have handles that allow convenient handling for the operator, as well as support means for setting in place and support for wooden planks.

Cependant les moyens de liaison entre les cadres ou les panneaux supposent une manipulation lente et laborieuse, il en arrive de même avec les moyens pour le soutien des planches en bois.However the means of connection between the frames or the panels assume slow handling and laborious, the same happens with the means to support for wooden boards.

DESCRIPTION DE L'INVENTIONDESCRIPTION OF THE INVENTION

Le cadre et le verrou selon la revendication 1 résolvent de manière pleinement satisfaisante la problématique antérieurement exposé, dans les différents aspects commentés.The frame and the lock according to claim 1 fully resolve the previously exposed problematic, in the different commented aspects.

Pour cela le cadre du panneau présente comme caractéristique fondamentale le fait d'incorporer, à chacun de ses bord, une platine métallique pourvue d'un alignement longitudinal d'orifices destinés à recevoir les verrous de fixation entre les cadres ou les panneaux. Les dits orifices ont un secteur central circulaire et deux projections radiales et opposées éraillées, avec une largeur inférieure au diamètre du secteur central et alignées longitudinalement dans le contexte de la platine métallique, tandis que chaque verrou est matérialisé dans un tourillon de crosse muni d'une tête à une de ses extrémités, d'un terminal tronconique à l'extrémité opposée et d'une broche transversale à proximité de cette dernière extrémité, de manière que le diamètre général du tourillon est l'adéquat pour passer à travers le secteur intermédiaire et circulaire de l'un quelconque des orifices des deux platines à unir, correspondantes aux deux cadres attenants, tandis que la broche diamétrale est dimensionnellement adéquate pour pouvoir passer à travers les projections extrêmes du dit orifice, dans une position déterminée, et pour constituer une butée de retenue lorsque le tourillon tourne 90° par rapport aux platines.For this, the framework of panel presents as a fundamental characteristic the fact to incorporate a metal plate on each of its edges provided with a longitudinal alignment of orifices intended for receive the fixing locks between the frames or panels. The said orifices have a circular central sector and two radial projections and opposite flayed, with a width less than the diameter of the central sector and aligned longitudinally in the background of the metal plate, while each lock is materialized in a butt stock with a head at one of its ends, from a tapered terminal to the opposite end and a cross pin to near this last end, so that the general diameter of the journal is adequate to pass to through the intermediate and circular sector of one any of the orifices of the two plates to be joined, corresponding to the two adjoining frames, while the diametral spindle is dimensionally adequate for being able to pass through the extreme projections of the said orifice, in a determined position, and to constitute a retaining stop when the journal turns 90 ° by compared to the decks.

La stabilisation définitive de l'ensemble, et plus concrètement le serrage définitif entre les platines des deux cadres, est réalisé avec la collaboration d'un coin qui traverse diamétralement le tourillon, à travers un orifice opérativement réalisé dans celui-ci, ce coin étant à une de ses extrémité coiffé par une tête d'actionnement qui facilite l'action de serrage ou coincement de celle-ci, tandis qu'à son extrémité opposée il est pourvue d'un rivetage ou emboutissage latéral qui agit en tant que butée d'incidence sur l'embouchure correspondante de la rainure diamétrale du tourillon, en empêchant le désaccouplement total entre le tourillon et le coin, et par conséquent, la perte éventuelle d'un de ces deux éléments.The final stabilization of the whole, and more concretely the final tightening between the plates of the two frames, is made with the collaboration of a corner which crosses diametrically the trunnion, through a orifice operatively produced therein, this corner being at one end capped by an actuating head which facilitates the clamping action or jamming thereof, while at its opposite end it is provided with a side riveting or stamping which acts as bearing stop on the corresponding mouth of the diametral groove of the journal, preventing the total uncoupling between the pin and the corner, and by Consequently, the possible loss of one of these two elements.

Comme complément de la structura décrite, le cadre de chaque panneau incorpore une série d'emboutissages intérieurs qui déterminent des épaulements sur lesquels sont appuyés les bords de la planche constitutive de la surface de coffrage proprement dite.As a complement to the structure described, the frame of each panel incorporates a series of internal stampings which determine the shoulders on which the edges of the board forming the formwork surface proper.

    • RÉALISATION PRÉFÉRÉE DE L'INVENTIONPREFERRED EMBODIMENT OF THE INVENTION

    Au moyen de ces figures l'on peut observer que le cadre que l'on préconise est configuré à base d'un cadre proprement dit (1), de contour rectangulaire, rigidifié au moyen d'une série d'entretoises (2) déterminantes d'une structure réticulaire, comme il en est le cas de n'importe quel cadre de coffrage classique, mais avec la particularité spéciale que le cadre proprement dit (1) est obtenu à base d'une série de platines (3) pourvues chacune d'elles d'un alignement longitudinal d'orifices (4), dans chacun desquels on établit un secteur intermédiaire, en correspondance avec la propre référence (4) , de configuration circulaire, et deux secteurs extrêmes (4') radialement éraillés et en opposition, de préférence dans le sens longitudinal, par rapport à la platine (3).By means of these figures it can be observed that the recommended framework is configured based on a framework proper (1), rectangular in outline, stiffened at by means of a series of spacers (2) determining a reticular structure, as is the case with any what a classic formwork frame, but with the special feature that the frame itself (1) is obtained from a series of plates (3) each provided of them of a longitudinal alignment of orifices (4), in each of which an intermediate sector is established, correspondence with own reference (4), of circular configuration, and two extreme sectors (4 ') radially flailed and in opposition, preferably in the longitudinal direction, relative to the plate (3).

    Ces orifices (4), opérativement en regard de ceux de la platine (3) dans l'accouplement entre les cadres, lorsque ceux-ci adoptent un positionnement coplanaire, ou bien opérativement en regard de profilés angulaires et auxiliaires, avec le même genre d'orifices, lorsque les cadres ou panneaux doivent adopter un positionnement angulaire, il sont destinés au passage des verrous qui complètent l'objet de l'invention, comme celui représenté dans la figure 4 à 7.These orifices (4), operatively opposite those of the plate (3) in the coupling between the frames, when these adopt a coplanar positioning, or well operatively opposite angular profiles and auxiliary, with the same kind of orifices, when the frames or panels must be positioned angular, they are intended for the passage of locks which complete the subject of the invention, such as that shown in Figure 4 to 7.

    Chaque verrou est matérialisé dans un tourillon (5), de diamètre en accord avec celui du secteur central des orifices (4), à travers lesquels il est susceptible de servir de passage, le quel est facilité par l'existence dans ledit tourillon (5) d'un terminal tronconique (6), qui coiffe le tourillon (5) par son extrémité opposée dans une tête (7), tandis qu'aux environs du terminal tronconique (6) se trouve une broche diamétrales (8) à son tour dimensionnellement adéquate pour traverser les platines (3) à travers les prolongements radiaux et opposés (4') de ses orifices (4). Each lock is materialized in a pin (5), in diameter in agreement with that of the central sector of holes (4), through which it is likely to serve as a passage, which is facilitated by existence in said pin (5) of a frustoconical terminal (6), which caps the journal (5) at its opposite end in a head (7), while in the vicinity of the frustoconical terminal (6) there is a diametric pin (8) in turn dimensionally suitable for crossing the plates (3) through the radial and opposite extensions (4 ') of its holes (4).

    Le tourillon (5) est aussi pourvu à proximité de sa tête (7) d'une large rainure diamétrale (9) dans laquelle se trouve un coin (10) coiffé à son tour et par extrémité plus large dans un tête (11) d'actionnement tandis qu'à son extrémité opposée il est pourvu d'un emboutissage latéral (12), spécialement visible dans le détail de la figure 7, qui empêche son désaccouplement par rapport au tourillon (5).The pin (5) is also provided near its head (7) of a wide diametrical groove (9) in which is a corner (10) capped in turn and by end wider in an actuating head (11) while at its opposite end it is provided with a lateral stamping (12), especially visible in the detail of FIG. 7, which prevents its uncoupling from the journal (5).

    Conformément à cette structuration l'ensemble inséparable constitué par le tourillon (5) et le coin (10) est accouplable dans les orifices opposés (4) des platines perforées (3) qui appartiennent à deux panneaux de coffrage contigus, évidemment en situation de parallélisme entre la broche transversale (8) du premier ensemble et les prolongements radiaux (4') des orifices précités (4). Après ledit accouplement le tourillon doit subir une rotation de 90° pour que sa broche transversale (8) soit perpendiculaire aux prolongements (4') des orifices (4), en constituant une butée d'appui sur une des platines (3), l'opposée à l'adaptation du coin (10), ce qui fait que lors du déplacement axial du dit coin (10) au sein de la rainure (9) du tourillon, il se produit un serrage d'une platine par rapport à une autre, qui assure une union rapide, solide et efficace entre les panneaux de coffrage.In accordance with this structure, the whole inseparable formed by the pin (5) and the corner (10) can be coupled in the opposite holes (4) of the plates perforated (3) which belong to two formwork panels contiguous, obviously in a situation of parallelism between the transverse pin (8) of the first set and the radial extensions (4 ') of the aforesaid orifices (4). After said coupling the journal must undergo a rotation of 90 ° so that its transverse spindle (8) is perpendicular to the extensions (4 ') of the orifices (4), in constituting a support stop on one of the plates (3), opposite to the adaptation of the wedge (10), so that when of the axial displacement of said corner (10) within the groove (9) of the trunnion, a tightening of a plate occurs compared to another, which ensures rapid union, solid and effective between the formwork panels.

    En retournant à nouveau au cadre (1), celui-ci est pourvu d'une série d'emboutissages (13) tout le long de son périmètre, orientés vers l'intérieur et espacés du bord interne du cadre par une étendue coïncidente avec l'épaisseur des planches en bois constitutives du coffrage proprement dit, de manière que ces emboutissages agissent comme des butées de retenue marginale pour lesdites planches, conjointement avec les butées établies par les entretoises intérieures (2). Returning to frame (1) again, it is provided with a series of stampings (13) along its perimeter, facing inwards and spaced from the edge internal of the frame by an extent coincident with the thickness of the wooden planks making up the formwork itself, so that these stampings act as marginal retaining stops for said boards, together with the stops established by the interior spacers (2).

    Pour le reste, le cadre, comme il est classique, il sera pourvu d'orifices (14) pour le passage des barres d'écartement, et entre ses entretoises, on établira des barres (15) en guise de poignées.For the rest, the framework, as it is classic, it will be provided with holes (14) for the passage of the bars spacing, and between its spacers, we will establish bars (15) as handles.

    On obtient de la sorte une structure légère, caractéristique déterminante étant donné l'utilisation manuellement portable prévue pour les panneaux de coffrage, dans laquelle les dits panneaux sont facilement interaccouplables, avec des unions solides et résistantes.We thus obtain a light structure, defining characteristic given the use manually portable provided for formwork panels, in which said panels are easily inter-coupling, with solid and resistant unions.
