Description
Domaine de l’inventionField of invention
L’invention appartient au domaine de la construction et du bâtiment, et plus spécifiquement à la réalisation de dalles, planchers en béton, poutre, coffrage, ou encore platelages de circulation et recette à matériaux. Elle concerne plus spécifiquement un dispositif apte à supporter provisoirement au moins un élément, tel que par exemple une poutrelle permettant la réalisation de telles structures, notamment sur un chantier de construction.The invention belongs to the field of construction and building, and more specifically to the production of slabs, concrete floors, beams, formwork, or even circulation decking and material acceptance. It relates more specifically to a device able to temporarily support at least one element, such as for example a beam allowing the realization of such structures, in particular on a construction site.
Etat antérieur de la techniquePrior state of the art
Les opérations de pose en hauteur d’éléments reposant sur des structures porteuses telles que des poutres ou des dalles notamment, sont soumises à des exigences très strictes en termes de sécurité. Typiquement, la pose de dalles préfabriquées ou non, nécessite le renforcement temporaire des appuis au niveau de la structure porteuse, en l’espèce un mur, un poteau ou une poutre, par l’adjonction de poutrelles sous les dalles.Installation operations at height of elements resting on load-bearing structures such as beams or slabs in particular, are subject to very strict requirements in terms of safety. Typically, the laying of prefabricated or non-prefabricated slabs requires the temporary reinforcement of the supports at the level of the load-bearing structure, in this case a wall, a post or a beam, by adding beams under the slabs.
Traditionnellement, de telles poutrelles sont reçues à l’extrémité supérieure d’étais reposant sur le sol. Or, une telle configuration engendre un encombrement au sol du chantier, qui peut s’avérer rédhibitoire dans les passages étroits tels que couloirs, escaliers, etc. Cet encombrement, outre qu’il occasionne une gêne pour les opérateurs, constitue également un frein pour les équipes de secours, le cas échéant dépêchées sur place. Par ailleurs, dans le cadre des chantiers de grande hauteur, la mise en œuvre de tels étaiements engendre un grand nombre de manipulations, tout particulièrement chronophages pour les opérateurs.Traditionally, such beams are received at the upper end of props resting on the ground. However, such a configuration creates a footprint on the site floor, which can prove to be prohibitive in narrow passages such as corridors, stairs, etc. This congestion, in addition to causing an inconvenience for the operators, also constitutes a brake for the emergency teams, if necessary dispatched on the spot. Furthermore, in the context of high-rise construction sites, the implementation of such shoring generates a large number of manipulations, which are particularly time-consuming for the operators.
Afin de s’affranchir de ces inconvénients, il a été proposé de remplacer les étais ou structure d’étaiement par des sabots d’étaiement, également dénommés dans le domaine considéré par corbeaux ou consoles.In order to overcome these drawbacks, it has been proposed to replace the props or shoring structure with shoring shoes, also referred to in the field under consideration as corbels or brackets.
Ces dispositifs sont constitués traditionnellement d’une paroi d’appui fixée contre le mur ou contre toute structure porteuse, à proximité du niveau où doit se positionner la poutrelle à recevoir, et présentent une paroi de support qui porte une tige de vérin manuelle, à déplacement vertical en service, et dont l’extrémité supérieure reçoit une platine sur laquelle doit reposer ladite poutrelle. Un tel dispositif a par exemple été écrit dans le document US 3,900,179.These devices traditionally consist of a support wall fixed against the wall or against any load-bearing structure, close to the level where the beam to be received must be positioned, and have a support wall which carries a manual jack rod, vertical displacement in service, and whose upper end receives a plate on which said beam must rest. Such a device has for example been written in the document US 3,900,179.
Si, incontestablement, ces sabots d’étaiement ou corbeaux, dimensionnés en conséquence, remplissent leurs fonctions et permettent de libérer le chantier des étais traditionnels, leur mise en œuvre se heurte à un certain nombre de difficultés.If, incontestably, these shoring shoes or corbels, dimensioned accordingly, fulfill their functions and make it possible to free the site from traditional props, their implementation comes up against a certain number of difficulties.
Parmi celles-ci figure tout d’abord leur réglage en hauteur selon une horizontalité rendue nécessaire par les contraintes du chantier et, plus particulièrement, par celles de l’horizontalité de la dalle, par exemple, destinée à être reçue sur les poutrelles.Among these is first of all their height adjustment according to a horizontality made necessary by the constraints of the site and, more particularly, by those of the horizontality of the slab, for example, intended to be received on the beams.
D’autre part, les sabots d’étaiement traditionnels comportent, comme déjà dit, une platine verticale, destinée à venir se fixer réversiblement contre la structure de soutien et notamment le mur porteur, au voisinage du niveau de réception desdites poutrelles et, corollairement, de la dalle, laissant traditionnellement, nonobstant la course verticale de la tige du vérin, peu de place pour permettre, après séchage de la dalle ou scellement de l’élément préfabriqué, leur enlèvement.On the other hand, the traditional shoring shoes comprise, as already said, a vertical plate, intended to be fixed reversibly against the support structure and in particular the load-bearing wall, in the vicinity of the level of reception of the said beams and, as a corollary, of the slab, leaving traditionally, notwithstanding the vertical stroke of the cylinder rod, little room to allow, after drying of the slab or sealing of the prefabricated element, their removal.
En outre, ces dispositifs s’avèrent d’un poids relativement conséquent, constituant un frein à leur manipulation, et notamment à leur mise en place et à leur démontage, les rendant dès lors peu pratiques, et en outre de mise en œuvre chronophage.In addition, these devices prove to be relatively heavy, constituting an obstacle to their handling, and in particular to their installation and dismantling, therefore making them impractical, and furthermore time-consuming to implement.
Enfin, ces dispositifs s’avèrent peu ergonomiques.Finally, these devices are not very ergonomic.
L’objectif recherché par la présente invention est de proposer un dispositif du type en question, de manipulation simple, tant lors du montage que du démontage, notamment en raison de l’accessibilité optimisée du système de fixation, et dont le poids des éléments unitaires constitutifs du dispositif est relativement réduit.The objective sought by the present invention is to propose a device of the type in question, of simple handling, both during assembly and disassembly, in particular because of the optimized accessibility of the fastening system, and whose weight of the unit elements components of the device is relatively small.
A cet effet, l’invention vise un dispositif de soutien provisoire d’au moins un élément entrant dans le processus de réalisation d’une partie d’un ouvrage, en d’autres termes un sabot d’étaiement, apte à être fixé amoviblement sur une structure porteuse, et notamment un mur, un poteau, une poutre, et destiné à supporter au moins ledit élément en vue de la réalisation de dalles ou prédalles en béton, de poutres, de platelages, etc.To this end, the invention relates to a temporary support device for at least one element entering into the process of producing part of a structure, in other words a shoring shoe, capable of being removably fixed on a load-bearing structure, and in particular a wall, a post, a beam, and intended to support at least said element with a view to producing concrete slabs or pre-slabs, beams, decking, etc.
Ce dispositif comprend :
– une platine, pourvue d’une face plane, apte à être fixée contre la structure porteuse en question, pourvue au voisinage de son extrémité supérieure d’un orifice traversant destiné à coopérer avec un organe de fixation sur ladite structure porteuse, et munie au voisinage de son extrémité inférieure d’un organe mâle de réception, orienté sensiblement perpendiculairement par rapport à la platine, et percé de deux orifices traversants en vis-à-vis ;
– une console escamotable, munie d’un moyen de réception et de guidage orienté en service verticalement d’un organe de réglage en hauteur, et typiquement d’un vérin manuel, muni à son extrémité supérieure de moyens de réception dudit élément, et pourvue d’un organe femelle apte à coopérer avec l’organe mâle de la platine, ledit organe femelle étant pourvu d’un rebord d’appui contre ladite platine, et étant également percés de deux orifices traversants en vis-à-vis, destinés, lorsque la console est reçue sur la platine, à être sensiblement alignées avec les orifices traversants de l’organe mâle de réception de la platine ;
– un axe amovible apte à traverser simultanément les orifices traversants, respectivement des organes mâle et femelle de la console et de la platine lorsque la console est en place sur la platine, et ainsi à solidariser réversiblement la console et la platine.This device includes:
– a plate, provided with a flat face, adapted to be fixed against the supporting structure in question, provided near its upper end with a through hole intended to cooperate with a fixing member on said supporting structure, and provided at the vicinity of its lower end of a male receiving member, oriented substantially perpendicular to the plate, and pierced with two through holes vis-à-vis;
– a retractable console, provided with a means for receiving and guiding vertically oriented in service of a height adjustment member, and typically a manual jack, provided at its upper end with means for receiving said element, and provided a female member capable of cooperating with the male member of the plate, said female member being provided with a bearing flange against said plate, and also being pierced with two through orifices facing each other, intended, when the console is received on the plate, to be substantially aligned with the through holes of the male member for receiving the plate;
- A removable axis capable of simultaneously passing through the through holes, respectively of the male and female members of the console and of the plate when the console is in place on the plate, and thus to reversibly secure the console and the plate.
En d’autres termes, l’invention consiste, en premier lieu, à proposer un tel support d’étaiement en deux parties essentielles distinctes, indépendantes l’une de l’autre, et solidarisables l’une à l’autre réversiblement, une platine de fixation et une console, l’organe de réglage en hauteur de cette dernière pouvant également être indépendant de ladite console.In other words, the invention consists, firstly, in proposing such a shoring support in two distinct essential parts, independent of each other, and reversibly attachable to each other, a fixing plate and a console, the height adjustment member of the latter also being able to be independent of said console.
Ce faisant, en premier lieu, on diminue le poids de l’ensemble ainsi constitué, puisqu’aussi bien, les différents éléments unitaires sont manipulés séparément l’un de l’autre, et en second lieu, ainsi qu’il sera vu infra, on facilite le positionnement et le démontage du sabot d’étaiement, puisqu’aussi bien, on procède tout d’abord à la fixation de la seule platine sur la structure porteuse considérée lors du montage, et on escamote ladite platine en l’absence de la console et du vérin associé lors du démontage, avec un accès aisé à l’orifice de fixation.In doing so, firstly, the weight of the assembly thus constituted is reduced, since the various unit elements are also handled separately from one another, and secondly, as will be seen below , positioning and dismantling of the shoring shoe is facilitated, since as well, one proceeds first of all to the fixing of the only plate on the supporting structure considered during assembly, and said plate is retracted in the absence of the console and the associated cylinder during dismantling, with easy access to the fixing hole.
Selon d’autres caractéristiques avantageuses de l’invention :
– La platine est pourvue d’un raidisseur longitudinal, orienté perpendiculairement par rapport au plan général dans lequel elle s’inscrit, s’étendant parallèlement à sa dimension principale depuis l’organe mâle de réception en direction de son extrémité supérieure, et corollairement, l’organe femelle de la console est muni d’un évidement ou encoche apte à autoriser l’emboitement dudit organe femelle sur l’organe mâle pour permettre au rebord d’appui de la console de prendre appui contre la platine.
– L’organe mâle de la platine et l’organe femelle de la console peuvent être de section transversale circulaire ;
– L’organe mâle de la platine et l’organe femelle de la console peuvent être de section transversale carrée ou rectangulaire, leurs faces latérales respectives orientées verticalement en service étant percées de lumières traversantes de section rectangulaire.
– Les lumières traversantes des faces parallèles d’un même côté, respectivement de l’organe mâle de réception de la platine et de l’organe femelle de la console sont situées à un niveau différent en service des lumières traversantes des faces parallèles de l’autre côté des organes en question.
– L’axe amovible apte à traverser simultanément les lumières traversantes, respectivement des organes mâle et femelle de la console et de la platine est constitué d’une clavette, avantageusement munie au voisinage de l’une de ses extrémités d’une saillie de dimension supérieure à l’une au moins des dimensions de l’une des lumières traversantes de l’organe femelle de la console.
– L’orifice traversant ménagé au voisinage de l’extrémité supérieure de la platine est de forme oblongue, et typiquement en forme de serrure, et notamment de largeur plus réduite au niveau de son extrémité supérieure que de sa base.
– Les moyens de réception dudit au moins un élément sont constitués d’une platine, éventuellement prolongée verticalement en service d’une double fourche permettant, selon une direction, de recevoir un élément, et par exemple une poutrelle simple, et dans la direction perpendiculaire, de recevoir deux éléments, et par exemple deux poutrelles.According to other advantageous characteristics of the invention:
– The plate is provided with a longitudinal stiffener, oriented perpendicular to the general plane in which it is inscribed, extending parallel to its main dimension from the male receiving member towards its upper end, and as a corollary, the female member of the console is provided with a recess or notch capable of allowing said female member to be fitted onto the male member to allow the support rim of the console to bear against the plate.
– The male part of the plate and the female part of the console can be of circular cross-section;
– The male component of the plate and the female component of the console can be of square or rectangular cross-section, their respective side faces oriented vertically in service being pierced with through slots of rectangular section.
– The through-lights of the parallel faces on the same side, respectively of the male receiver of the plate and of the female member of the console, are located at a different level in service from the through-lights of the parallel faces of the other side of the organs in question.
– The removable axis capable of simultaneously passing through the through slots, respectively of the male and female organs of the console and of the plate consists of a key, advantageously provided in the vicinity of one of its ends with a projection of dimension greater than at least one of the dimensions of one of the through slots of the female console member.
– The through hole provided in the vicinity of the upper end of the plate is oblong in shape, and typically in the shape of a keyhole, and in particular of smaller width at its upper end than at its base.
– The means for receiving said at least one element consist of a plate, optionally extended vertically in service by a double fork allowing, in one direction, to receive an element, and for example a simple beam, and in the perpendicular direction , to receive two elements, for example two beams.
