Tous ces différents systèmes sont relativement longs à mettre en place et à démonter, et requièrent une main d'oeuvre importante.All these different systems are relatively long to set up and dismantle, and require a large workforce.
On connaît par ailleurs les garde-corps constitués de quatre barrières reliées entre elles de façon à former un rectangle prévu pour entourer le contour d'une plaque de béton à installer. Lorsque deux plaques doivent être agencées l'une à la suite de l'autre, la barrière bloque l'accès d'une plaque à l'autre, réduisant fortement l'ergonomie du site de travail. Par ailleurs, la présence de quatre côtés engendre un poids relativement important, en particulier pour les garde-corps métalliques. Enfin, ces garde-corps sont construits de façon monobloc, et non démontables. Ainsi, pour le transport, il est en général utile de monopoliser un camion pour transporter un seul garde-corps.Railings consisting of four barriers connected to each other so as to form a rectangle designed to surround the contour of a concrete plate to be installed are also known. When two plates must be arranged one after the other, the barrier blocks access from one plate to the other, greatly reducing the ergonomics of the work site. Moreover, the presence of four sides generates a relatively large weight, especially for metal railings. Finally, these railings are constructed in a single piece, and not removable. Thus, for transportation, it is generally useful to monopolize a truck to transport a single guardrail.

La configuration présentée dans ce document requiert un serrage des pinces contre la dalle. En outre, le risque de glissement des pinces est important. Enfin, la dalle est requise pour créer la masse de contre-poids.The configuration presented in this document requires a clamping of the clamps against the slab. In addition, the risk of slipping of the tongs is important. Finally, the slab is required to create the weight against weight.
Pour pallier ces différents inconvénients, l'invention prévoit différents moyens techniques.To overcome these various disadvantages, the invention provides various technical means.
Tout d'abord, un premier objet de l'invention consiste à prévoir un procédé permettant de transporter les garde-corps de façon simple et économique.First, a first object of the invention is to provide a method for transporting railings in a simple and economical way.
Un autre objet de l'invention consiste à prévoir un garde-corps ergonomique, facilitant la mise en place de plaques préfabriquées en côte à côte, sans entraver les déplacements entre deux plaques voisines.Another object of the invention is to provide an ergonomic railing, facilitating the establishment of prefabricated plates side by side, without hindering movement between two adjacent plates.
Un autre objet de l'invention consiste à prévoir un garde-corps pouvant être posé sur une plaque de béton préfabriquée sans nécessiter de fixation entre la plaque et le garde-corps.Another object of the invention is to provide a railing that can be placed on a prefabricated concrete plate without requiring attachment between the plate and the guardrail.
Pour ce faire, l'invention prévoit un garde-corps temporaire, en particulier pour chantier de construction, composé d'un châssis formant une base se prolongeant de part et d'autre d'un axe d'équilibre (E-E) et destinée à coopérer de façon amovible avec une plaque à assembler à un objet en cours de construction et faisant partie, après assemblage, dudit objet à construire, et d'une barrière garde-corps, disposée dans un plan sensiblement transversal au plan de la base lorsque placé en position déployée, la répartition des masses des différents éléments du garde-corps étant prévue de façon à ce que ce dernier soit sensiblement équilibré autour de l'axe d'équilibre lorsque le garde-corps est dans ladite position déployée, le châssis comportant des poutres métalliques massiques dimensionnées de façon à contrebalancer le poids de la barrière garde-corps disposée à l'opposé afin que le garde-corps puisse supporter une charge importante agissant contre la barrière.To do this, the invention provides a temporary railing, particularly for a construction site, composed of a frame forming a base extending on either side of an equilibrium axis (EE) and intended for removably cooperate with a plate to be assembled to an object under construction and forming part, after assembly, of said object to be constructed, and a railing barrier disposed in a plane substantially transverse to the plane of the base when placed in the deployed position, the distribution of the masses of the various elements of the railing being provided so that the latter is substantially balanced around the axis of equilibrium when the guardrail is in said extended position, the frame comprising Mass metal beams dimensioned to counterbalance the weight of the guardrail disposed opposite so that the guardrail can withstand a heavy load acting against the a barrier.
Selon une telle architecture de garde-corps, la plaque de béton en cours d'installation est protégée sur un seul des côtés longs, permettant ainsi de créer un agencement de deux plaques de béton en duo sans barrière entre les deux. Les déplacements et manipulations entre les plaques voisines sont ainsi facilités. Compte tenu de l'espace réduit sur cet emplacement, un tel environnement de travail avec moins d'obstacles permet d'améliorer le confort de travail tout en améliorant la sécurité des occupants.According to such a railing architecture, the concrete plate being installed is protected on only one of the long sides, thus creating an arrangement of two concrete plates duo without barrier between the two. The movements and manipulations between neighboring plates are thus facilitated. Given the limited space on this site, such a work environment with fewer obstacles can improve working comfort while improving occupant safety.
Selon un autre mode de réalisation avantageux, la barrière est mobile entre deux positions extrêmes, à savoir une position repliée, dans laquelle ladite barrière est positionnée dans un plan sensiblement parallèle à celui de la base au voisinage de celle-ci, et une position déployée, dans laquelle ladite barrière est positionnée dans un plan sensiblement perpendiculaire à celui de la base.According to another advantageous embodiment, the barrier is movable between two extreme positions, namely a folded position, in which said barrier is positioned in a plane substantially parallel to that of the base in the vicinity thereof, and an extended position, wherein said barrier is positioned in a plane substantially perpendicular to that of the base.

La
Le garde-corps est avantageusement conçu de façon à être modulable entre deux positions, à savoir une position repliée, tel que montré aux
En position repliée, le garde-corps occupe un volume restreint et est ainsi mieux adapté aux phases de transports, tel que montré aux
Le passage d'un mode à l'autre peut être réalisé de multiples façons, par exemple en montant la barrière garde corps de façon repliable contre la base, ou en prévoyant la barrière garde-corps amovible de la base.The transition from one mode to the other can be achieved in many ways, for example by mounting the barrier guard foldably against the base, or providing the barrier guardrail removable base.
Un portillon 5, de préférence monté pivotant, permet de protéger la zone d'extrémité de la plaque de béton. En outre, en position fermée, tel que montré aux
La base 2 et/ou la barrière 3 de garde-corps sont avantageusement extensibles. Dans l'exemple illustré, des barres télescopiques montées à chaque extrémité de la barrière garde-corps peuvent être ajustées à la longueur souhaitée ou complètement escamotées en faisant glisser les deux parties tubulaires l'une dans l'autre. Un système de blocage tel qu'une cheville ou tout autre moyen connu permet de verrouiller la partie extensible à la longueur souhaitée.The
Les différents éléments constituants du garde-corps selon l'invention sont avantageusement réalisés en matériaux métalliques, de préférence massiques, de façon à présenter un poids relativement important. De cette façon, un garde-corps métallique peut être adapté pour supporter une charge importante telle qu'un ouvrier perdant l'équilibre qui viendrait brusquement saisir la barrière, ou un matériau de construction basculant contre la barrière, sans que cette dernière bascule vers le vide, à l'opposée de la plaque de béton.The various elements constituting the railing according to the invention are advantageously made of metal materials, preferably mass, so as to have a relatively large weight. In this way, a metal railing can be adapted to support a heavy load such as a worker losing the balance that would suddenly seize the barrier, or a building material flipping against the barrier, without the latter switches to the empty, opposite the concrete slab.
La
Préalablement à cette phase, l'ensemble a été formé, en posant un garde-corps sur une plaque préfabriquée. La barrière du garde-corps a été déployée. Dans l'exemple illustré, les deux portillons présents ont été positionnés de façon à protéger les zones latérales des extrémités.Prior to this phase, the assembly was formed by placing a railing on a prefabricated plate. The guardrail barrier has been deployed. In the example illustrated, the two gates present have been positioned so as to protect the lateral zones of the ends.
Après la pose de l'ensemble, les câbles (ou tout autre moyen de fixation) sont détachés de la plaque de béton. Le travail sur chantier peut ensuite être poursuivi à l'endroit où la plaque sécurisée a été placée.After installation of the assembly, the cables (or any other means of attachment) are detached from the concrete plate. Work on site can then be continued where the secure plate has been placed.
Du fait de sa conception équilibrée, malgré une architecture asymétrique, le garde-corps peut être soulevé aisément. En outre, le garde-corps peut rester en place même s'il est posé sans fixation à la plaque. Un tel type d'agencement permet de réaliser les opérations de pose et dépose de façon simple, rapide, et efficace. Comme on peut l'apercevoir à la
L'architecture asymétrique, avec préférentiellement une barrière sur un seul des deux côtés longs, permet d'agencer deux plaques en côte à côte avec des barrières disposées à l'opposée afin de conserver une circulation facile et aisée entre les deux plaques. Les intervenants bénéficient alors d'une plus grande aisance dans leurs mouvements et déplacements.The asymmetrical architecture, preferably with a barrier on only one of the two long sides, makes it possible to arrange two plates side by side with barriers arranged opposite to maintain easy and easy circulation between the two plates. Stakeholders then benefit from greater ease in their movements and movements.
Des crochets (non montrés) ou autres moyens de préhension sont prévus sur la plaque préfabriquée. Ces crochets permettent d'attacher la plaque avec le moyen de levage afin de procéder à l'installation de l'ensemble plaque de béton surmontée d'un garde-corps à l'emplacement prévu sur le chantier.Hooks (not shown) or other gripping means are provided on the prefabricated plate. These hooks are used to attach the plate with the lifting means to proceed with the installation of the concrete plate assembly surmounted by a guardrail at the location provided on the site.
La base 2 comporte des zones ou moyens d'accrochage 8 telles que des platines d'angle trouées tel qu'illustré aux
Dans une variante où la plaque de béton est fixée au garde-corps, l'opération de levage de l'ensemble garde-corps posé sur une plaque de béton peut être effectuée en utilisant les zones d'accrochage 8 du garde-corps.In a variant where the concrete slab is attached to the railing, the lifting operation of the railing assembly placed on a concrete slab can be carried out using the
Diverses variantes de réalisation, non illustrées aux figures, permettent de modifier ou compléter les modes de mises en oeuvre préalablement décrits. Par exemple, le contrepoids sous forme de barre massive préalablement décrit peut être remplacé ou complété par un ou plusieurs contrepoids ponctuels posés à un ou plusieurs points de fixation ou supports positionnés à des points permettant une répartition équilibrée du poids. Une barrière de contrepoids, de forme et/ou de dimension différente de la barrière de garde-corps, peut être prévue en remplacement ou en complément d'autres moyens de contrepoids.Various embodiments, not illustrated in the figures, make it possible to modify or complete the modes of implementation previously described. For example, the counterweight in the form of solid bar previously described can be replaced or supplemented by one or more point counterweight placed at one or more attachment points or supports positioned at points allowing a balanced distribution of weight. A counterweight barrier of different shape and / or size of the guardrail barrier may be provided as a replacement for or in addition to other counterweight means.
Des moyens anti-glissement 6 sont avantageusement prévus sous la base, de façon à augmenter le coefficient de friction entre le garde-corps et la plaque de béton. Par exemple, aux
Les
Les Figures et leurs descriptions faites ci-dessus illustrent l'invention plutôt qu'elles ne la limitent. En particulier, l'invention et ses différentes variantes viennent d'être décrites en relation avec un exemple particulier comportant un garde-corps en structure métallique, et une plaque préfabriquée en béton, telle qu'une pré-dalle ou une dalle alvéolaire.The figures and their descriptions made above illustrate the invention rather than limiting it. In particular, the invention and its various variants have just been described in connection with a particular example comprising a railing metal structure, and a prefabricated concrete plate, such as a pre-slab or alveolar slab.
Néanmoins, il est évident pour un homme du métier que l'invention peut être étendue à d'autres modes de réalisation dans lesquels en variantes, on prévoit par exemple un garde-corps constitué de matériaux sensiblement légers tels que des matériaux composites ou du bois. Dans un tel cas, il est avantageux de fixer le garde-corps à la plaque de béton de façon à éviter le risque de basculement. Le garde-corps et le procédé selon l'invention peuvent aussi être utilisés avec des plaques autres que les pré-dalles ou dalles alvéolaires en béton préalablement décrites. Par ailleurs, le garde-corps selon l'invention peut aussi être utilisé pour la pose de dalles coulées sur place, et/ou pour toute installation nécessitant une sécurisation en hauteur.Nevertheless, it is obvious to one skilled in the art that the invention can be extended to other embodiments in which, for example, there is provided for example a railing consisting of substantially light materials such as composite materials or wood . In such a case, it is advantageous to fix the railing to the concrete plate so as to avoid the risk of tipping. The guardrail and the method according to the invention can also be used with plates other than the pre-slabs or cellular slabs previously described. Furthermore, the guardrail according to the invention can also be used for laying slabs cast on site, and / or for any installation requiring securing height.
