Description

La présente invention a trait à un balcon préfabriqué, à un ensemble comportant un tel balcon préfabriqué ainsi qu'à une construction comportant un tel ensemble.The present invention relates to a prefabricated balcony, to an assembly comprising such a prefabricated balcony and to a construction comprising such an assembly.

L'invention concerne le domaine du bâtiment et, plus particulièrement, celui de la fabrication, en usine, d'éléments de construction destinés à être utilisés pour la réalisation d'une construction. L'invention trouvera, alors, plus particulièrement, une application dans le cadre d'un élément de construction constitué par un balcon préfabriqué.The invention relates to the field of the building and, more particularly, that of the manufacture, in the factory, of building elements intended to be used for the realization of a construction. The invention will find, then, more particularly, an application in the context of a building element consisting of a prefabricated balcony.

L'on connait, d'ores et déjà, des balcons préfabriqués comportant, d'une part, un plateau usuellement réalisé en béton et, d'autre part, des armatures comportant une partie interne s'étendant à l'intérieur d'un tel plateau et une partie externe, s'étendant à l'extérieur d'un tel plateau, et destinée à s'étendre à l'intérieur d'une dalle que comporte une construction.Already known, prefabricated balconies comprising, on the one hand, a plate usually made of concrete and, on the other hand, reinforcements having an internal portion extending inside a such tray and an outer portion extending outside of such a tray, and intended to extend within a slab that includes a construction.

A ce propos, on observera qu'un tel balcon préfabriqué est réalisé en un matériau plein et intègre des armatures usuellement métalliques de sorte qu'il présente un poids relativement élevé ce qui limite substantiellement son élancement. De plus, lors de la réalisation d'une construction, un tel balcon préfabriqué est positionné en façade de cette construction, ceci par l'intermédiaire d'un engin de levage. Là encore, en raison du poids élevé d'un tel balcon préfabriqué, il est nécessaire de faire appel à des engins de levage spécifiquement dimensionnés sur la base d'un tel poids ayant pour effet d'augmenter sensiblement les coûts liés au levage.In this regard, it will be observed that such a prefabricated balcony is made of a solid material and integrates usually metal frames so that it has a relatively high weight which substantially limits its slenderness. In addition, during the realization of a construction, such prefabricated balcony is positioned in front of this construction, this by means of a hoist. Again, because of the high weight of such a prefabricated balcony, it is necessary to use lifting gear specifically sized on the basis of such a weight having the effect of significantly increase the costs of lifting.

De plus, un tel balcon doit être positionné en façade, ceci en sorte que la partie externe de ses armatures s'étende, à l'intérieur de la construction, en un emplacement correspondant sensiblement à celui qu'occupera la dalle à l'intérieur de laquelle s'étendra et sera noyée cette partie externe d'armatures.In addition, such a balcony must be positioned in front, this so that the outer part of its frames extends, inside the construction, in a location corresponding substantially to that which will occupy the slab inside. from which will extend and will be embedded this external part of frames.

A ce propos, on observera que cette partie externe d'armature s'étend, usuellement, dans le prolongement du plateau que comporte le balcon préfabriqué de sorte qu'au final la surface supérieure du plateau de ce balcon préfabriqué s'étend sensiblement au niveau de la surface supérieure de la dalle une fois celle-ci coulée.In this respect, it will be observed that this external frame portion extends, usually, in the extension of the tray that includes the prefabricated balcony so that in the end the The upper surface of the tray of this prefabricated balcony extends substantially to the level of the upper surface of the slab once it is poured.

Or, un tel balcon doit respecter un certain nombre de normes notamment relatives, d'une part, à l'écoulement des eaux pluviales (hauteur de rejingot comprise entre 2,5 et 3cm) et, d'autre part, à l'accessibilité du balcon aux personnes à mobilité réduite (ressaut entre l'intérieur de la construction et le balcon inférieur à 2cm).However, such a balcony must comply with a number of standards including relating, on the one hand, to the flow of rainwater (height of rejingot between 2.5 and 3cm) and, on the other hand, to the accessibility from the balcony to people with reduced mobility (jump between the inside of the building and the balcony less than 2cm).

Aussi, lorsque la surface supérieure du plateau du balcon préfabriqué s'étend sensiblement au niveau de la surface supérieure de la dalle, l'accessibilité peut être garantie s'il est prévu une menuiserie de hauteur appropriée et compatible avec les normes relatives à une telle accessibilité (typiquement une hauteur inférieure à 2cm). Cependant, une telle hauteur de menuiserie ne permet pas de satisfaire aux normes relatives à l'écoulement des eaux pluviales.Also, when the upper surface of the prefabricated balcony plate extends substantially at the level of the upper surface of the slab, the accessibility can be guaranteed if there is provided a joinery of appropriate height and compatible with the standards for such accessibility (typically a height less than 2cm). However, such a carpentry height does not meet the standards for the flow of rainwater.

Une solution a été trouvée en prévoyant, à proximité de l'extrémité fixe du balcon préfabriqué, un caniveau surmonté d'un caillebotis. Cependant, la présence d'un tel caniveau réduit substantiellement la hauteur utile du balcon ce qui entraîne une réduction de la portée de ce balcon.A solution has been found by providing, near the fixed end of the prefabricated balcony, a gutter topped with a grating. However, the presence of such a gutter substantially reduces the useful height of the balcony which results in a reduction of the scope of this balcony.

Une autre solution consiste à prévoir un ressaut coulé en oeuvre et permettant de satisfaire aux normes en matière d'écoulement des eaux pluviales. Cette solution nécessite, alors, de compléter le balcon préfabriqué par un plancher ainsi que par une pluralité de plots, surmontant le plateau de ce balcon préfabriqué, et surmontés par le plancher, ceci de manière à amener ce plancher au niveau du ressaut. Cette solution nécessite, également et pour satisfaire aux normes d'accessibilité, de prévoir une rampe à l'intérieur de la construction. Cependant, cette solution présente un certain nombre d'inconvénients notamment relatifs à la nécessité de la mise en place d'une pluralité de plots par-dessus le plateau du balcon préfabriqué ainsi qu'à la nécessité d'aménager une rampe entraînant la perte d'une surface habitable importante à l'intérieur de la construction.Another solution is to provide a cast jump implemented and to meet the standards for rainwater flow. This solution requires, then, to complete the prefabricated balcony with a floor and a plurality of pads, surmounting the plate of the prefabricated balcony, and surmounted by the floor, so as to bring this floor at the projection. This solution also requires, and to meet accessibility standards, to provide a ramp inside the building. However, this solution has a number of drawbacks including the need for the establishment of a plurality of studs over the tray of the prefabricated balcony and the need to develop a ramp resulting in the loss of a significant living space inside the building.

Afin de remédier aux inconvénients précédents, il a été imaginé un balcon préfabriqué en décaissé. Un tel balcon nécessite, certes, de positionner, d'une part, des plots par-dessus le plateau d'un tel balcon et, d'autre part, un plancher par-dessus ces plots mais permet de satisfaire aux normes relatives à l'écoulement des eaux pluviales ainsi qu'à celles relatives à l'accessibilité aux personnes à mobilité réduite. Cependant, pour réaliser un tel balcon préfabriqué en décaissé, il est nécessaire de prévoir un ferraillage dense et complexe. Un tel ferraillage complexifie la réalisation d'un tel balcon préfabriqué et en augmente substantiellement le poids. Ceci entraîne une réduction de la portée d'un tel balcon préfabriqué et impose, là encore, l'utilisation d'engins de levage tels que mentionnés ci-dessus.In order to overcome the previous disadvantages, it was imagined a prefabricated balcony disbursed. Such a balcony requires, of course, to position, on the one hand, studs over the plate of such a balcony and, secondly, a floor over these pads but meets the standards for the rainwater flow as well as those relating to accessibility for people with reduced mobility. However, to achieve such a prefabricated balcony disbursed, it is necessary to provide a dense and complex reinforcement. Such reinforcement makes the production of such a prefabricated balcony more complex and substantially increases its weight. This leads to a reduction in the range of such a prefabricated balcony and imposes, again, the use of lifting gear as mentioned above.

La présente invention se veut de remédier aux inconvénients des balcons préfabriqués de l'état de la technique.The present invention aims to overcome the disadvantages of prefabricated balconies of the state of the art.

A cet effet, l'invention concerne un balcon préfabriqué, au moins en partie réalisé en un matériau hydraulique, présentant une extrémité libre ainsi qu'une extrémité fixe, opposée à l'extrémité libre et destinée à venir se positionner au moins à proximité d'une façade d'une construction, ce balcon préfabriqué comportant au moins un plateau présentant deux grands côtés. Ce balcon préfabriqué est caractérisé par le fait qu'il comporte :

  • au moins deux nervures chacune, d'une part, comportant une extrémité libre et, d'autre part, s'étendant entre l'extrémité libre et l'extrémité fixe du balcon ainsi qu'en saillie par rapport à l'un desdits grands côtés dudit plateau ;
  • des moyens de réception pour recevoir un plancher, ces moyens de réception étant agencés en sorte qu'à l'extrémité libre des nervures soit associé au moins un tel moyen de réception.
For this purpose, the invention relates to a prefabricated balcony, at least partly made of a hydraulic material, having a free end and a fixed end, opposite to the free end and intended to be positioned at least close to a facade of a construction, this prefabricated balcony having at least one tray with two long sides. This prefabricated balcony is characterized by the fact that it comprises:
  • at least two ribs each, on the one hand, having a free end and, on the other hand, extending between the free end and the fixed end of the balcony and projecting from one of said large sides of said tray;
  • receiving means for receiving a floor, these receiving means being arranged such that at the free end of the ribs is associated with at least one such receiving means.

Selon une autre caractéristique, le balcon comporte des armatures comportant, chacune, d'une part, une partie interne d'armature s'étendant à l'intérieur d'une des nervures et, d'autre part, une partie externe d'armature s'étendant à l'extérieur d'une telle nervure et à partir de l'extrémité fixe du balcon.According to another characteristic, the balcony comprises reinforcements each comprising, on the one hand, an internal part of reinforcement extending inside one of the ribs and, on the other hand, an outer armature portion extending outside of such a rib and from the fixed end of the balcony.

Une caractéristique additionnelle consiste en ce que chaque armature comporte au moins une barre ou analogue, réalisée en matériau composite ou en acier.An additional feature is that each armature comprises at least one bar or the like, made of composite material or steel.

Une autre caractéristique consiste en ce que le balcon comporte des moyens d'évacuation des eaux pluviales et que le grand côté du plateau, par rapport auquel les nervures s'étendent en saillie, comporte une surface qui présente, par rapport à l'horizontale, une inclinaison en pente descendante en direction de l'extrémité libre et/ou de l'extrémité fixe du balcon, cette inclinaison constituant, au moins en partie, les moyens d'évacuation des eaux pluviales.Another feature is that the balcony has means for evacuation of rainwater and that the long side of the plate, relative to which the ribs project, has a surface which has, with respect to the horizontal, a slope downward slope towards the free end and / or the fixed end of the balcony, this inclination constituting, at least in part, the rainwater evacuation means.

Une caractéristique additionnelle concerne le fait que le balcon comporte des moyens d'isolation thermique, interposés entre les nervures, voire traversés par ces nervures, et s'étendant à partir de l'extrémité fixe du balcon et en direction de l'extrémité libre de ce balcon.An additional feature is that the balcony has thermal insulation means, interposed between the ribs, or even traversed by these ribs, and extending from the fixed end of the balcony and towards the free end of this balcony.

Une autre caractéristique consiste en ce que le balcon comporte au moins une paroi arrière, d'une part, s'étendant en retrait par rapport à l'extrémité fixe du balcon ainsi qu'à partir du plateau et des nervures et, d'autre part, délimitant, au moins avec ces nervures, un logement pour la réception des moyens d'isolation thermique et/ou constituant un moyen de protection de ces moyens d'isolation.Another feature is that the balcony has at least one rear wall, on the one hand, extending recessed with respect to the fixed end of the balcony and from the plate and the ribs and other on the one hand, delimiting, at least with these ribs, a housing for the reception of the thermal insulation means and / or constituting a means for protecting these isolation means.

Selon une autre caractéristique, les nervures comportent des moyens pour améliorer d'adhérence du béton de la construction sur une telle nervure.According to another characteristic, the ribs comprise means for improving the adhesion of the concrete of the construction on such a rib.

Le balcon préfabriqué selon l'invention est au moins en partie réalisé en un béton contenant des fibres, notamment un béton fibré à ultra hautes performances (BFUP).The prefabricated balcony according to the invention is at least partly made of a concrete containing fibers, especially an ultra high performance fiber concrete (UHPC).

L'invention concerne, également, un ensemble comportant un balcon préfabriqué et un plancher surmontant ce balcon préfabriqué, ce dernier présentant les caractéristiques décrites ci-dessus. Ce plancher est au moins en partie constitué par des plaques ou par des lames réalisées en bois, en pierre, en matériau composite, ou en béton, plus particulièrement en un béton contenant des fibres, notamment un béton fibré à ultra hautes performances (BFUP).The invention also relates to an assembly comprising a prefabricated balcony and a floor above this prefabricated balcony, the latter having the characteristics described above. This floor is at least partly made up of plates or blades made of wood, stone, composite material, or concrete, more particularly a concrete containing fibers, especially ultra-high performance fiber-reinforced concrete (UHPC).

Finalement, l'invention concerne une construction comportant, d'une part, une dalle présentant une surface supérieure s'étendant dans un plan et, d'autre part, un ensemble comportant un balcon préfabriqué ainsi qu'un plancher surmontant ce balcon préfabriqué et présentant une surface supérieure s'étendant dans un plan. En fait, dans cette construction, l'ensemble présente les caractéristiques décrites ci-dessus tandis que la dalle et/ou l'ensemble sont positionnés et/ou conçus en sorte que l'écart entre le plan de la surface supérieure du plancher de l'ensemble et le plan de la surface supérieure de la dalle soit inférieur à 2cm.Finally, the invention relates to a construction comprising, on the one hand, a slab having an upper surface extending in a plane and, on the other hand, an assembly comprising a prefabricated balcony and a floor surmounting this prefabricated balcony and having an upper surface extending in a plane. In fact, in this construction, the assembly has the characteristics described above while the slab and / or assembly are positioned and / or designed so that the gap between the plane of the upper surface of the floor of the together and the plane of the upper surface of the slab is less than 2cm.

Ainsi, le balcon préfabriqué conforme à l'invention comporte des nervures ce qui peut éviter la mise en place, voire la fixation, de plots pour le montage d'un plancher.Thus, the prefabricated balcony according to the invention comprises ribs which can prevent the establishment or fixing of studs for mounting a floor.

De plus, ce balcon préfabriqué comporte des armatures qui s'étendent en partie à l'intérieur des nervures et en partie et à l'extérieur de ces nervures, plus particulièrement dans le prolongement de ces nervures. Lors du positionnement d'un tel balcon préfabriqué en façade d'une construction, la partie externe de ces armatures est positionnée en un emplacement correspondant sensiblement à celui qu'occupera la dalle. Du fait du positionnement des armatures par rapport aux nervures, celles-ci seront alors positionnées en regard de dalle de sorte que, après montage du plancher par-dessus ces nervures, l'écart entre la surface supérieure de cette dalle (nu supérieur de la dalle brute) et la surface supérieure du plancher sera conforme aux normes relatives à l'accessibilité aux personnes à mobilité réduite.In addition, this prefabricated balcony has reinforcements which extend partly inside the ribs and partly and outside these ribs, especially in the extension of these ribs. When positioning such a prefabricated balcony facade of a construction, the outer portion of these frames is positioned in a location corresponding substantially to that which will occupy the slab. Due to the positioning of the reinforcements relative to the ribs, they will then be positioned facing the slab so that, after mounting the floor over these ribs, the gap between the upper surface of this slab (upper naked of the rough slab) and the upper surface of the floor will comply with standards for accessibility to persons with reduced mobility.

En outre, ce balcon préfabriqué comporte un plateau, à partir duquel s'étendent les nervures, et en direction duquel s'écoulent les eaux pluviales. Ce plateau, après positionnement du balcon par rapport à la construction, définit un rejingot conforme aux normes relatives à l'écoulement des eaux pluviales.In addition, this prefabricated balcony has a plateau, from which extend the ribs, and in which flow the rainwater. This plateau, after positioning of the balcony in relation to the construction, defines a rejingot in accordance with the norms relating to the flow of rain water.

Finalement, ce balcon préfabriqué est au moins en partie réalisé en un béton contenant des fibres, notamment un béton fibré à ultra hautes performances (usuellement dénommé BFUP). L'utilisation d'un tel matériau permet, pour des caractéristiques mécaniques identiques à un balcon préfabriqué de l'état de la technique, de limiter les éléments de structure aux seules nervures et, ainsi, de réduire la quantité de matériau utilisée pour la réalisation d'un balcon préfabriqué conforme à l'invention et, donc, le poids d'un tel balcon préfabriqué. Ceci permet, avantageusement, d'allonger l'élancement et/ou la portée d'un tel balcon préfabriqué et/ou de recourir à des engins de levage moins spécifiques et, donc, de réduire les coûts liés au levage. Ceci permet, également, d'optimiser l'étalement du balcon, ceci après avoir positionné un tel balcon en façade et dans l'attente du durcissement du béton de la dalle. Finalement, la diminution de poids permet d'optimiser la descente de charges et, de ce fait, le dimensionnement de la structure porteuse du bâtiment.Finally, this prefabricated balcony is at least partly made of a concrete containing fibers, especially an ultra high performance fiber concrete (usually called BFUP). The use of such a material makes it possible, for mechanical characteristics identical to a prefabricated balcony of the state of the art, to limit the structural elements to only the ribs and, thus, to reduce the quantity of material used for the production. a prefabricated balcony according to the invention and, therefore, the weight of such a prefabricated balcony. This advantageously makes it possible to lengthen the slenderness and / or the reach of such a prefabricated balcony and / or to use less specific lifting gear and thus reduce the costs associated with lifting. This also makes it possible to optimize the spreading of the balcony, after having positioned such a balcony in front and waiting for the concrete to harden the slab. Finally, the reduction in weight makes it possible to optimize the descent of loads and, as a result, the sizing of the load-bearing structure of the building.

D'autres buts et avantages de la présente invention apparaîtront au cours de la description qui va suivre se rapportant à des modes de réalisation qui ne sont donnés qu'à titre d'exemples indicatifs et non limitatifs.Other objects and advantages of the present invention will become apparent from the following description relating to embodiments which are given by way of indicative and non-limiting examples.

L'invention concerne le domaine du bâtiment et, plus particulièrement, celui de la fabrication, en usine, d'éléments de construction destinés à être utilisés pour la réalisation d'une construction.The invention relates to the field of the building and, more particularly, that of the manufacture, in the factory, of building elements intended to be used for the realization of a construction.

En fait, la présente invention concerne un élément de construction constitué par un balcon préfabriqué.In fact, the present invention relates to a building element consisting of a prefabricated balcony.

Un tel balcon préfabriqué 1 est au moins en partie réalisé en un matériau hydraulique et présente une extrémité libre 2 ainsi qu'une extrémité fixe 3, opposée à l'extrémité libre 2, et destinée à venir se positionner au moins à proximité d'une façade F d'une construction C, voire (et de préférence) en applique contre (plus particulièrement par-dessus) un voile que comporte une telle façade F.Such prefabricated balcony 1 is at least partly made of a hydraulic material and has a free end 2 and a fixed end 3, opposite to the free end 2, and intended to be positioned at least near a facade F of a construction C, or even (and preferably) applied against (more particularly above) a veil that includes such a facade F.

Ce balcon préfabriqué 1 comporte au moins un plateau 4 présentant deux grands côtés (40 ; 40') dont l'un (40) est destiné à constituer la face supérieure de ce plateau 4 tandis que l'autre (40') est destiné à constituer la face inférieure de ce plateau 4, ceci après positionnement dudit balcon préfabriqué 1 en façade F de la construction C.This prefabricated balcony 1 comprises at least one plate 4 having two long sides (40; 40 ') one of which (40) is intended to constitute the upper face of this plate 4 while the other (40') is intended for constitute the lower face of this plate 4, this after positioning of said prefabricated balcony 1 in front F of the construction C.

Selon l'invention, ce balcon préfabriqué 1 comporte au moins deux nervures 5 chacune s'étendant entre l'extrémité libre 2 et l'extrémité fixe 3 du balcon 1 ainsi qu'en saillie par rapport à l'un (40) desdits grands côtés (40 ; 40') dudit plateau 4.According to the invention, this prefabricated balcony 1 comprises at least two ribs 5 each extending between the free end 2 and the fixed end 3 of the balcony 1 and projecting from one (40) of said large sides (40; 40 ') of said plate 4.

En fait, une telle nervure 5 s'étend en saillie par rapport au grand côté 40 dudit plateau 4 destiné à constituer la face supérieure de plateau 4, ceci après positionnement dudit balcon préfabriqué 1 en façade F de la construction C.In fact, such a rib 5 extends projecting with respect to the long side 40 of said plate 4 intended to constitute the upper face of plate 4, this after positioning of said prefabricated balcony 1 in facade F of the construction C.

Une telle nervure 5 s'étend donc en saillie par rapport à un tel grand côté 40 du plateau 4 et comporte, d'une part, une extrémité fixe 50 au niveau de laquelle cette nervure 5 coopère avec ledit plateau 4 et, d'autre part, une extrémité libre 51, opposée à ladite extrémité fixe 50.Such a rib 5 thus extends projecting with respect to such a large side 40 of the plate 4 and comprises, on the one hand, a fixed end 50 at which this rib 5 cooperates with said plate 4 and, on the other hand, a free end 51, opposite to said fixed end 50.

Selon un mode préféré de réalisation, lesdites nervures 5 sont parallèles entre elles.According to a preferred embodiment, said ribs 5 are parallel to each other.

Une autre caractéristique consiste en ce que ces nervures 5 peuvent être réalisées dans le même matériau que le plateau 4.Another characteristic is that these ribs 5 can be made of the same material as the plate 4.

Selon l'invention, ce balcon préfabriqué 1 comporte, encore, des moyens de réception 6 pour recevoir un plancher P, ces moyens de réception 6 étant agencés en sorte qu'à l'extrémité libre 51 des nervures 5 (plus particulièrement à l'extrémité libre 51 de chaque nervure 5) soit associé au moins un tel moyen de réception 6.According to the invention, this prefabricated balcony 1 comprises, again, receiving means 6 for receiving a floor P, these receiving means 6 being arranged so that at the free end 51 of the ribs 5 (more particularly to the free end 51 of each rib 5) is associated with at least one such receiving means 6.

En fait, au moins un de ces moyens de réception 6 est constitué par une surface d'appui 60 que comporte l'extrémité libre 51 d'une des nervures 5.In fact, at least one of these receiving means 6 is constituted by a bearing surface 60 that includes the free end 51 of one of the ribs 5.

Une autre caractéristique consiste en ce que le balcon préfabriqué 1 comporte des armatures 7 comportant, chacune, d'une part, une partie interne d'armature 70 s'étendant à l'intérieur d'une des nervures 5 et, d'autre part, une partie externe d'armature 71 s'étendant à l'extérieur d'une telle nervure 5 et à partir de l'extrémité fixe 3 du balcon 1.Another characteristic consists in that the prefabricated balcony 1 comprises reinforcements 7 each comprising, on the one hand, an inner part of reinforcement 70 extending inside one of the ribs 5 and, on the other hand , an outer portion of frame 71 extending outside of such a rib 5 and from the fixed end 3 of the balcony 1.

En fait, une telle armature 7 s'étend longitudinalement par rapport à une telle nervure 5.In fact, such a frame 7 extends longitudinally with respect to such a rib 5.

On observera que ledit balcon préfabriqué 1 comporte, plus particulièrement, des armatures supérieures 8 comportant, chacune, d'une part, une partie externe d'armature 81 s'étendant à l'extérieur d'une des nervures 5 et à partir de l'extrémité fixe 3 du balcon 1 et, d'autre part, une partie interne d'armature 80 s'étendant à l'intérieur d'une telle nervure 5 et que comporte l'extrémité libre 51 d'une telle nervure 5.It will be observed that said prefabricated balcony 1 comprises, more particularly, upper armatures 8 each comprising, on the one hand, an outer armature portion 81 extending outside one of the ribs 5 and from fixed end 3 of the balcony 1 and, on the other hand, an inner part of armature 80 extending inside such a rib 5 and that has the free end 51 of such a rib 5.

De manière alternative ou (et de préférence) additionnelle, le balcon préfabriqué 1 comporte des armatures inférieures 9, comportant, chacune, d'une part, une partie externe d'armature 91 s'étendant à l'extérieur d'une des nervures 5 et à partir de l'extrémité fixe 3 du balcon 1 et, d'autre part, une partie interne d'armature 90 s'étendant à l'intérieur d'une telle nervure 5 ainsi qu'à proximité du plateau 4.Alternatively or (and preferably) additional, the prefabricated balcony 1 comprises lower armatures 9, each comprising, on the one hand, an outer portion of armature 91 extending outside one of the ribs 5 and from the fixed end 3 of the balcony 1 and, on the other hand, a part internal reinforcement 90 extending inside such a rib 5 and in the vicinity of the plate 4.

Une telle armature inférieure 9 travaille en compression et est conçue pour reprendre un effort horizontal de compression qui se forme en partie inférieure d'une nervure 5.Such a lower reinforcement 9 works in compression and is designed to take up a horizontal compressive force which is formed in the lower part of a rib 5.

Une autre caractéristique consiste en ce que chaque armature 7 (notamment chaque armature supérieure 8 et/ou chaque armature inférieure 9) comporte au moins une barre ou analogue, réalisée en matériau composite (notamment en résine synthétique renforcée en fibres de verre) ou en acier (notamment en acier de type à haute adhérence et/ou inoxydable).Another characteristic consists in that each reinforcement 7 (in particular each upper reinforcement 8 and / or each lower reinforcement 9) comprises at least one bar or the like, made of composite material (in particular of synthetic resin reinforced with glass fibers) or of steel (In particular high adhesion and / or stainless steel type).

Selon un mode préféré de réalisation chaque armature supérieure 8 comporte deux barres en matériau composite ou en acier.According to a preferred embodiment each upper armature 8 comprises two bars of composite material or steel.

En fait, le diamètre de ces barres est compris entre 10 et 14mm, de préférence de l'ordre de 12mm.In fact, the diameter of these bars is between 10 and 14 mm, preferably of the order of 12 mm.

Selon un mode préféré de réalisation, le plateau 4 du balcon préfabriqué 1 est dépourvue d'armature, ceci au moins pour les portions d'un tel plateau 4 s'étendant entre les nervures 5.According to a preferred embodiment, the plate 4 of the prefabricated balcony 1 is devoid of reinforcement, this at least for the portions of such a plate 4 extending between the ribs 5.

Ainsi, en dehors des nervures 5, le balcon ne comporte pas d'armature.Thus, apart from the ribs 5, the balcony has no reinforcement.

Une autre caractéristique du balcon préfabriqué 1 selon l'invention consiste en ce qu'il comporte des moyens 10 d'évacuation des eaux pluviales.Another characteristic of the prefabricated balcony 1 according to the invention consists in that it comprises means 10 for evacuation of rainwater.

A ce propos, on observera que le grand côté 40 du plateau 4, par rapport auquel les nervures 5 s'étendent en saillie, comporte une surface qui présente, par rapport à l'horizontale, une inclinaison en pente descendante en direction de l'extrémité libre 2 et/ou en direction de l'extrémité fixe 3 du balcon 1, cette inclinaison constituant, au moins en partie, les moyens 10 d'évacuation des eaux pluviales.In this regard, it will be observed that the long side 40 of the plate 4, with respect to which the ribs 5 extend projecting, comprises a surface which has, with respect to the horizontal, a downward sloping inclination in the direction of the free end 2 and / or towards the fixed end 3 of the balcony 1, this inclination constituting, at least in part, the means 10 for evacuation of rainwater.

De manière additionnelle et pour une surface du grand côté 40 du plateau 4 présentant une inclinaison en pente descendante en direction de l'extrémité libre 2 du balcon 1, ces moyens d'évacuation 10 peuvent comporter au moins un conduit d'évacuation 100 traversant une paroi avant 20, que comporte l'extrémité libre 2 du balcon 1, et qui s'étend perpendiculairement aux nervures 5 et/ou au moins un conduit d'évacuation 101 traversant au moins une des nervures 5, ceci à proximité de l'extrémité libre 2 du balcon 1.Additionally, and for a surface of the long side 40 of the plate 4 having a downward slope inclination towards the free end 2 of the balcony 1, these evacuation means 10 may comprise at least one duct 100 through a front wall 20, which has the free end 2 of the balcony 1, and which extends perpendicularly to the ribs 5 and / or at least one exhaust duct 101 passing through at least one of the ribs 5, this near the free end 2 of the balcony 1.

Pour une surface du grand côté 40 du plateau 4 présentant une inclinaison en pente descendante en direction de l'extrémité fixe 3 du balcon 1, ces moyens d'évacuation 10 peuvent comporter au moins conduit d'évacuation traversant au moins une des nervures 5, ceci à proximité de l'extrémité fixe 3 du balcon 1.For a surface of the long side 40 of the plate 4 having a downward sloping inclination towards the fixed end 3 of the balcony 1, these evacuation means 10 may comprise at least one through-duct passing through at least one of the ribs 5, this near the fixed end 3 of the balcony 1.

Une autre caractéristique du balcon préfabriqué 1 selon l'invention consiste en ce qu'il comporte des moyens d'isolation thermique 11, interposés entre les nervures 5, voire (et de préférence) traversés par ces nervures 5 (comme illustré figures 2 à 6), et s'étendant à partir de l'extrémité fixe 3 du balcon 1 et en direction de l'extrémité libre 2 de ce balcon 1.Another characteristic of the prefabricated balcony 1 according to the invention consists in that it comprises thermal insulation means 11, interposed between the ribs 5, or even (and preferably) traversed by these ribs 5 (as illustrated Figures 2 to 6 ), and extending from the fixed end 3 of the balcony 1 and towards the free end 2 of the balcony 1.

Selon un mode préféré de réalisation, ces moyens d'isolation thermique 11 s'étendent, au niveau de l'extrémité fixe 3 du balcon 1, sur toute la largueur du balcon 1 et/ou sur toute la longueur de cette extrémité fixe 3 de ce balcon 1.According to a preferred embodiment, these thermal insulation means 11 extend, at the fixed end 3 of the balcony 1, over the entire width of the balcony 1 and / or over the entire length of this fixed end 3 of this balcony 1.

De tels moyens d'isolation thermique 11 sont, alors, intégrés au balcon 1 et permettent de limiter les ponts thermiques entre, d'une part, le balcon préfabriqué 1 et, d'autre part, la façade F (plus particulièrement un voile que comporte cette façade F) et/ou la dalle D.Such thermal insulation means 11 are then integrated in the balcony 1 and limit the thermal bridges between, on the one hand, the prefabricated balcony 1 and, on the other hand, the facade F (more particularly a veil that has this facade F) and / or slab D.

En fait, de tels moyens d'isolation thermique 11 s'étendent au moins à partir des extrémités latérales 52, que comportent les nervures 5, et qui constituent au moins en partie l'extrémité fixe 3 du balcon préfabriqué 1 (en particulier lorsque le plateau 4 du balcon 1 est en retrait par rapport à cette extrémité fixe 3). Selon un mode de réalisation particulier, de tels moyens d'isolation 11 s'étendent, encore, à partir d'une extrémité fixe 41, que comporte le plateau 4, et qui constitue (avec les extrémités latérales 52 des nervures 5) l'extrémité fixe 3 du balcon 1 (en particulier lorsque ce plateau 4 et ces nervures 5 s'étendent jusqu'à cette extrémité fixe 3).In fact, such thermal insulation means 11 extend at least from the lateral ends 52, which comprise the ribs 5, and which constitute at least partly the fixed end 3 of the prefabricated balcony 1 (in particular when the plateau 4 of the balcony 1 is set back with respect to this fixed end 3). According to a particular embodiment, such insulating means 11 extend, again, from a fixed end 41, which comprises the plate 4, and which constitutes (with the lateral ends 52 of the ribs 5) the fixed end 3 of balcony 1 (especially when this plateau 4 and these ribs 5 extend to this fixed end 3).

Tel que mentionné ci-dessus, cette extrémité fixe 3 du balcon 1 est destinée à venir se positionner au moins à proximité d'une façade F d'une construction C, voire (et de préférence) en applique contre (plus particulièrement par-dessus) un voile que comporte une telle façade F.As mentioned above, this fixed end 3 of the balcony 1 is intended to be positioned at least in the vicinity of a facade F of a construction C, or even (and preferably) applied against (more particularly over ) a veil that includes such a facade F.

A ce propos, on observera que ce sont, plus particulièrement, au moins les extrémités latérales 52 des nervures 5 qui viennent alors se positionner au moins à proximité d'une telle façade F d'une telle construction C, voire (et de préférence) en applique contre (plus particulièrement par-dessus) un voile que comporte une telle façade F.In this regard, it will be observed that it is more particularly at least the lateral ends 52 of the ribs 5 which are then positioned at least in the vicinity of such a facade F of such a construction C, even (and preferably) applied against (more particularly above) a veil that includes such a facade F.

Une caractéristique additionnelle consiste en ce que le balcon préfabriqué 1 comporte au moins une paroi arrière 30 s'étendant en retrait par rapport à l'extrémité fixe 3 du balcon préfabriqué 1, plus particulièrement en retrait par rapport aux extrémités latérales 52 des nervures 5, voire encore par rapport à l'extrémité fixe 41 du plateau 4. Une telle paroi arrière 30 s'étend, également, à partir du plateau 4 et des nervures 5, plus particulièrement entre ces nervures 5, notamment entre deux nervures consécutives 5. En fait, une telle paroi arrière 30 s'étend perpendiculairement au plateau 4 et aux nervures 5.An additional feature is that the prefabricated balcony 1 has at least one rear wall 30 extending recessed with respect to the fixed end 3 of the prefabricated balcony 1, more particularly recessed with respect to the lateral ends 52 of the ribs 5, or even with respect to the fixed end 41 of the plate 4. Such a rear wall 30 also extends from the plate 4 and the ribs 5, more particularly between these ribs 5, in particular between two consecutive ribs 5. In fact, such a rear wall 30 extends perpendicularly to the plate 4 and to the ribs 5.

Une telle paroi arrière 30 délimite, au moins avec ces nervures 5 (voire encore avec le plateau 4 lorsque celui-ci s'étend jusqu'à l'extrémité fixe 3 du balcon 1), un logement pour la réception des moyens d'isolation thermique 11 et/ou constitue un moyen de protection de ces moyens d'isolation 11.Such a rear wall 30 delimits, at least with these ribs 5 (or even with the plate 4 when it extends to the fixed end 3 of the balcony 1), a housing for the reception of the insulation means 11 and / or is a means of protection of these insulation means 11.

En fait, une telle paroi arrière 30 constitue, plus particulièrement, un parement.In fact, such a rear wall 30 is, more particularly, a facing.

Encore une autre caractéristique consiste en ce que les nervures 5 comportent une portion d'extrémité 53, s'étendant à partir de l'extrémité fixe 3 du balcon 1 (plus particulièrement à partir de l'extrémité latérale 52 d'une telle nervure 5) et en direction de l'extrémité libre 2 de ce balcon 1, et réalisée en un matériau isolant thermique.Yet another characteristic consists in that the ribs 5 comprise an end portion 53 extending from the fixed end 3 of the balcony 1 (more particularly from the lateral end 52 of such a rib 5 ) and towards the free end 2 of the balcony 1, and made of a thermal insulating material.

La présence d'une portion d'extrémité 53 de nervure 5 réalisée en un matériau isolant thermique permet, alors avantageusement, de limiter le pont thermique entre, d'une part, le balcon 1 et, d'autre part, cette façade F (plus particulièrement un voile que comporte cette façade F) et/ou la dalle D.The presence of an end portion 53 of rib 5 made of a thermal insulating material makes it possible, advantageously, to limit the thermal bridge between, on the one hand, the balcony 1 and, on the other hand, this facade F ( more particularly a veil that includes this facade F) and / or the slab D.

De manière alternative ou additionnelle, une telle portion d'extrémité 53 de nervure 5 présente une section réduite par rapport au restant d'une telle nervure 5 (figure 6).In an alternative or additional manner, such an end portion 53 of rib 5 has a reduced section relative to the remainder of such a rib 5 ( figure 6 ).

En fait, une telle portion d'extrémité 53 s'étend, plus particulièrement, entre l'extrémité fixe 3 du balcon 1 et la paroi arrière 30 susmentionnée.In fact, such an end portion 53 extends, more particularly, between the fixed end 3 of the balcony 1 and the rear wall 30 mentioned above.

Tel que mentionné ci-dessus, cette extrémité fixe 3 de balcon 1 (plus particulièrement l'extrémité latérale 52 des nervures 5) est destinée à venir se positionner au moins à proximité d'une façade F d'une construction C, voire (et de préférence) en applique contre (plus particulièrement par-dessus) un voile que comporte une telle façade F.As mentioned above, this fixed end 3 of balcony 1 (more particularly the lateral end 52 of the ribs 5) is intended to be positioned at least near a facade F of a construction C, or even (and preferably) applied against (more particularly above) a veil that includes such a facade F.

En fait, c'est, plus particulièrement, la portion d'extrémité 53 d'une telle nervure 5 qui est, alors, destinée à venir se positionner au moins à proximité d'une façade F d'une construction C, voire (et de préférence) en applique contre (plus particulièrement par-dessus) un voile que comporte une telle façade F.In fact, it is, more particularly, the end portion 53 of such a rib 5 which is, then, intended to be positioned at least in the vicinity of a facade F of a construction C, or even (and preferably) applied against (more particularly above) a veil that includes such a facade F.

Une caractéristique additionnelle consiste en ce que les nervures 5 peuvent encore comporter des moyens 54 pour améliorer l'adhérence, sur une telle nervure 5, du béton de la construction C, plus particulièrement du béton de la dalle D de cette construction C.An additional feature is that the ribs 5 may further comprise means 54 for improving the adhesion, on such a rib 5, of the concrete of the construction C, more particularly the concrete of the slab D of this construction C.

En fait et tel que visible sur la figure 6, ces moyens pour améliorer l'adhérence 54 s'étendant à partir de l'extrémité fixe 3 du balcon 1 (plus particulièrement à partir de l'extrémité latérale 52 des nervures 5 constituant cette extrémité fixe 3 et/ou à partir de la portion d'extrémité 53 de ces nervures 5), ceci dans une direction opposée à l'extrémité libre 2 du balcon 1.In fact and as visible on the figure 6 these means for improving the adhesion 54 extending from the fixed end 3 of the balcony 1 (more particularly from the lateral end 52 of the ribs 5 constituting this fixed end 3 and / or from the portion end 53 of these ribs 5), this in a direction opposite to the free end 2 of the balcony 1.

De tels moyens pour améliorer l'adhérence 54 peuvent adopter la forme d'indentations ou analogue.Such means for improving adhesion 54 may take the form of indentations or the like.

Lorsque le balcon 1 comporte de tels moyens pour améliorer l'adhérence 54, ceux-ci 54 sont, alors, destinés à venir se positionner au moins à proximité d'une façade F d'une construction C, voire (et de préférence) en applique contre (plus particulièrement par-dessus) un voile que comporte une telle façade F.When the balcony 1 comprises such means to improve the adhesion 54, these 54 are, then, intended to be positioned at least in the vicinity of a facade F of a construction C, or (preferably) in applies against (more particularly above) a veil that includes such a facade F.

Finalement, ledit balcon préfabriqué 1 peut, encore, comporter des moyens pour la réception d'au moins un garde-corps et/ou des moyens pour la réception d'au moins un câble d'alimentation en énergie électrique.Finally, said prefabricated balcony 1 may, again, comprise means for receiving at least one guardrail and / or means for receiving at least one electric power supply cable.

En fait, dans cet ensemble, le balcon préfabriqué 1 présente les caractéristiques décrites ci-dessus.The invention also relates to an assembly comprising a prefabricated balcony 1 and a floor P surmounting this prefabricated balcony 1, more particularly the ribs 5 of this balcony 1. In fact, in this assembly, the prefabricated balcony 1 has the features described herein. -above.

Le plancher P est au moins en partie constitué par des plaques P' (notamment adoptant la forme de dalles ou analogue), par des lames ou analogue. Ces plaques P' ou ces lames sont réalisées en bois, en pierre, en matériau composite, ou en béton, plus particulièrement en un béton contenant des fibres, notamment un béton fibré à ultra hautes performances (BFUP).The floor P is at least partly formed by plates P '(in particular adopting the form of slabs or the like), by blades or the like. These plates P 'or these blades are made of wood, stone, composite material, or concrete, more particularly a concrete containing fibers, including ultra-high performance fiber concrete (UHPC).

De telles plaques P' comportent une face inférieure présentant des excroissances conçues aptes à coopérer avec les nervures susmentionnées, ceci pour leur positionnement par rapport à ces nervures 5.Such plates P 'comprise a lower face having protrusions designed adapted to cooperate with the aforementioned ribs, this for their positioning with respect to these ribs 5.

Finalement, l'invention concerne une construction C comportant, d'une part et intérieurement à la construction C, une dalle D présentant une surface supérieure s'étendant dans un plan et, d'autre part et extérieurement à la construction C, un ensemble comportant un balcon préfabriqué 1 ainsi qu'un plancher P surmontant ce balcon préfabriqué 1 et présentant une surface supérieure s'étendant dans un plan.Finally, the invention relates to a construction C comprising, on the one hand and internally to the construction C, a slab D having an upper surface extending in a plane and, on the other hand and externally to the construction C, a assembly comprising a prefabricated balcony 1 and a floor P overlying this prefabricated balcony 1 and having an upper surface extending in a plane.

De plus, la dalle D et/ou l'ensemble sont positionnés et/ou conçus en sorte que l'écart entre le plan de la surface supérieure du plancher P de l'ensemble et le plan de la surface supérieure de la dalle D soit inférieur à 2cm.In addition, the slab D and / or the assembly are positioned and / or designed so that the difference between the plane of the upper surface of the floor P of the assembly and the plane of the upper surface of the slab D is less than 2cm.

A ce propos, on observera que l'épaisseur de la dalle D (notamment de la chape que comporte cette dalle D) peut, alors, être choisie en sorte que cet écart soit inférieur à 2cm.In this respect, it will be observed that the thickness of the slab D (in particular of the slab which this slab D comprises) can then be chosen so that this difference is less than 2 cm.

De manière additionnelle ou alternative, en ce qui concerne ledit ensemble susmentionné, les nervures 5 et/ou les plaques P' du plancher P sont dimensionnées (plus particulièrement en ce qui concerne leur épaisseur) en sorte que cet écart soit inférieur à 2cm.In an additional or alternative manner, with regard to said aforementioned assembly, the ribs 5 and / or the plates P 'of the floor P are dimensioned (more particularly with regard to their thickness) so that this difference is less than 2 cm.

Cette construction peut, encore, comporter au moins une bavette B s'étendant par-dessus la ou les parois arrières 30, voire encore par-dessus la ou les nervures 5.This construction may also comprise at least one flap B extending over the rear wall (s) 30, or even over the rib (s) 5.

La présence d'une telle bavette B permet, avantageusement, d'une part, d'assurer l'écoulement des eaux pluviales en direction du plateau 4 et, d'autre part, de protéger les moyens d'isolation thermique 11 par rapport à ces eaux pluviales.The presence of such a flap B advantageously allows, on the one hand, to ensure the flow of rainwater towards the plate 4 and, on the other hand, to protect the thermal insulation means 11 relative to these rainwater.
