Description
La présente invention concerne un coffre-tunnel utilisé dans le domaine du bâtiment pour réceptionner un occultant et typiquement un volet roulant.The present invention relates to a tunnel box used in the building sector for receiving an occulting and typically a shutter.
Un tel coffre-tunnel se présente généralement et en référence à la
Il convient de le disposer au-dessus d'une embrasure de porte ou de fenêtre afin que l'occultant puisse venir masquer au besoin, ladite porte, ladite fenêtre. Il est en principe fabriqué majoritairement dans un matériau isolant d'un point de vue thermique pour limiter les échanges de calories entre l'intérieur et l'extérieur de l'habitation qu'il équipe. Il peut ainsi être fabriqué en matière synthétique alvéolaire, en polystyrène expansé, dans un moule de fabrication dont les côtés délimitent l'enveloppe du coffre-tunnel.It should be placed above a door or window embrasure so that the occultant can hide if necessary, said door, said window. It is in principle manufactured mainly in an insulating material from a thermal point of view to limit the heat exchange between the inside and the outside of the house that it equips. It can thus be made of cellular synthetic material, expanded polystyrene, in a mold of manufacture whose sides delimit the envelope of the trunk-tunnel.
Un premier état de la technique connu et présenté sur la
Un second état de la technique connu et présenté sur la
La présence de cette rainure R amoindrie l'épaisseur e de la paroi dans laquelle elle est réalisée. Par ailleurs les tiges ne doivent pas être situées trop près des faces de la paroi de jambage du coffre-tunnel, et notamment sa face interne, pour être efficaces et aussi pour ne pas apparaître à l'intérieur du coffre-tunnel. En pratique, les tiges doivent être situées à une distance d'au moins 10 mm des faces de ladite paroi latérale d'un coffre-tunnel fabriqué en polystyrène. En effet lorsqu'elles sont fabriquées en acier, elles pourraient s'oxyder à l'air libre. Elles pourraient encore frotter et détériorer les lames du tablier du volet roulant. Aussi, dans la pratique, on n'utilise pas de tige dans la paroi qui est creusée d'une rainure de réception de la patte de fixation, ce qui réduit la rigidité du coffre-tunnel.The presence of this groove R reduces the thickness e of the wall in which it is made. Furthermore, the rods must not be located too close to the faces of the jamb wall of the tunnel box, and in particular its inner face, to be effective and also not to appear inside the tunnel box. In practice, the rods must be located at a distance of at least 10 mm from the faces of said side wall of a tunnel box made of polystyrene. Indeed when they are made of steel, they could oxidize in the open air. They could still rub and deteriorate the blades of the shutter apron. Also, in practice, there is no rod in the wall which is hollowed a receiving groove of the bracket, which reduces the rigidity of the tunnel box.
Le but de l'invention est donc de proposer un coffre-tunnel pourvu d'une telle rainure de réception d'une patte de fixation et dont la rigidité demeure comparable à celle du coffre-tunnel décrit dans le premier état de la technique.The object of the invention is therefore to provide a tunnel box provided with such a groove for receiving a fastening tab and whose rigidity remains comparable to that of the tunnel box described in the first state of the art.
A cet effet, est proposé un coffre-tunnel destiné à réceptionner un mécanisme d'occultation d'une fenêtre, d'une porte, le coffre-tunnel étant prévu pour être ancré au-dessus d'un tableau délimitant l'encadrement de pose d'un dormant de la fenêtre, ou de la porte, le coffre-tunnel comprenant une paroi de voûte prolongée par au moins un bord, d'une paroi latérale, une rainure creusant depuis l'extérieur ladite paroi latérale et/ou la paroi de voûte, ladite rainure étant destinée à loger une patte de fixation/de renfort, ledit coffre-tunnel incorporant une armature de renfort de sa structure, comprenant des arceaux disposés radialement dans le volume de matière dudit coffre-tunnel, des tiges disposées longitudinalement dans le volume de matière dudit coffre-tunnel de sorte à réunir lesdits arceaux ; selon l'invention, la rainure est délimitée par une encoche qui est interrompue avant le bord libre de la paroi latérale ménageant un volume de matière élargi dans la partie basse de la paroi latérale et dans lequel prend place au moins une tige.For this purpose, a tunnel box is provided for receiving a mechanism for concealing a window, a door, the tunnel box being designed to be anchored above a table delimiting the installation frame. a window frame, or the door, the tunnel box including an arch wall extended by at least one edge, a side wall, a groove boring from the outside of said side wall and / or the arch wall, said groove being intended for housing a fastening / reinforcement lug, said tunnel box incorporating a reinforcing reinforcement of its structure, comprising arches arranged radially in the volume of material of said tunnel box, rods arranged longitudinally in the volume of material of said tunnel box; so as to join said arches; according to the invention, the groove is delimited by a notch which is interrupted before the free edge of the side wall providing a volume of expanded material in the lower part of the side wall and in which takes place at least one rod.
Bien que localement de plus faible épaisseur, la paroi latérale du coffre-tunnel de l'invention intègre cependant une tige qui, reliée à une pluralité d'arceaux, accroît de manière significative la rigidité du coffre-tunnel. Cette raideur accrue peut être utilisée pour solidariser rigidement la paroi latérale du coffre-tunnel avec un dormant d'une menuiserie.Although locally smaller, the side wall of the tunnel box of the invention, however, incorporates a rod which, connected to a plurality of hoops, significantly increases the rigidity of the tunnel box. This increased stiffness can be used to rigidly secure the side wall of the tunnel box with a frame of a carpentry.
Selon une caractéristique additionnelle de l'invention, un profilé chevauche le bord libre de la paroi latérale et ladite tige est positionnée à l'intérieur dudit profilé.According to an additional feature of the invention, a profile overlaps the free edge of the side wall and said rod is positioned inside said profile.
La tige et le profilé coopèrent pour rigidifier la partie basse de la paroi latérale du coffre-tunnel et qui est destinée à être liée avec le dormant.The rod and the profile cooperate to stiffen the lower part of the side wall of the tunnel box and which is intended to be linked with the frame.
Selon une caractéristique additionnelle de l'invention, une autre tige est disposée dans la partie arrondie de la paroi de voûte raccordée à ladite paroi latérale.According to an additional feature of the invention, another rod is disposed in the rounded portion of the arch wall connected to said side wall.
La raideur du coffre-tunnel est encore accrue de la sorte.The stiffness of the tunnel box is further increased in this way.
Selon une caractéristique additionnelle de l'invention, le coffre-tunnel comprend une patte de renfort, de fixation entre un linteau et un dormant d'une huisserie.According to an additional feature of the invention, the tunnel box comprises a reinforcement lug, fixing between a lintel and a frame of a frame.
Le coffre-tunnel rigidifié peut aussi inclure cette patte de liaison.The rigidified tunnel box may also include this link leg.

Les dimensions de la patte de fixation 200 sont comparables aux dimensions de la rainure de sorte qu'elle puisse être intégralement logée dans ladite rainure, exceptée la patte d'ancrage 230 qui dépasse de la face supérieure de la paroi de voûte V comme cela apparaît sur la

Dans une variante de réalisation non représentée, la patte d'ancrage de la patte de fixation est fixée par vissage sur un linteau existant ou préalablement coulé et durci. La patte d'ancrage est rabattue sur la face supérieure de la paroi de voûte et l'on procède à la fixation de la patte de fixation par vissage de ladite patte d'ancrage, depuis l'évidement du coffre-tunnel. On remarquera que cette patte d'ancrage peut être fixée sur la face inférieure du linteau ou sur une face frontale. Dans cette dernière hypothèse, le coffre-tunnel peut être dépourvu de l'encoche horizontale de la rainure dans sa paroi de voûte, seul subsiste le segment vertical de la rainure dans sa paroi latérale. Dans le même esprit, le coffre-tunnel peut n'être pourvu que d'un seul segment horizontal de la rainure dans sa paroi de voûte, la patte de fixation n'étant alors pas rentrée dans sa paroi latérale.In an alternative embodiment not shown, the anchoring tab of the fixing lug is fixed by screwing on an existing lintel or previously cast and hardened. The anchoring tab is folded down on the upper face of the arch wall and the fastening tab is fixed by screwing the anchor tab from the recess of the tunnel box. It will be noted that this anchoring tab may be fixed on the underside of the lintel or on a front face. In the latter case, the tunnel box may be devoid of the horizontal slot of the groove in its arch wall, only the vertical segment of the groove remains in its wall. lateral. In the same spirit, the tunnel box can be provided with only one horizontal segment of the groove in its arch wall, the fastening tab then not returned to its side wall.

Chaque patte de fixation 200 est retenue dans le coffre-tunnel si bien qu'il peut être livré prêt à être solidarisé avec le linteau et le dormant. Chaque patte de fixation 200 est masquée au moins en partie dans le coffre-tunnel 100, ce qui simplifie la pose de l'isolant thermique lorsqu'il est placé sur la face interne des murs. Chaque patte de fixation 200 relie directement ou indirectement le linteau L avec le dormant d'une menuiserie.Each
Par ailleurs, le coffre-tunnel est en principe fabriqué en modules de grande longueur que l'on recoupe ensuite en tronçons de longueurs standards et qui correspondent aux largeurs des tableaux de réception des dormants, majorées le cas échéant, de la longueur d'appui des extrémités du coffre-tunnel sur la maçonnerie.In addition, the tunnel box is in principle manufactured in long length modules which are then cut into standard length sections and corresponding to the widths of the receiving tables of the frames, plus, if necessary, the support length. tunnel box ends on the masonry.
Le coffre-tunnel peut avantageusement être préparé en usine afin qu'une ou plusieurs pattes de fixation soient placées dans des rainures correspondantes et choisies pour que la liaison entre le linteau et le dormant soit optimum.The tunnel box can advantageously be prepared in the factory so that one or more brackets are placed in corresponding grooves and selected so that the connection between the lintel and the frame is optimum.

Du côté de cette paroi latérale L1, une autre tige 136b est disposée dans une portion arrondie Pr constitutive de la paroi de voûte V et qui prolonge par le haut ladite paroi latérale L1. Dans cette région, il y a suffisamment de matière pour entourer correctement ladite tige pour accroître la rigidité de la partie haute du coffre-tunnel.On the side of this side wall L1, another
Le coffre-tunnel de l'invention présente, bien que pourvu d'une rainure de réception d'une patte de renfort, de fixation, une rigidité comparable aux coffres-tunnels conventionnels armés d'une armature de rigidification. Son coût de fabrication est également comparable aux coffres-tunnels connus de l'état de la technique.The trunk tunnel of the invention has, although provided with a receiving groove of a reinforcement lug, a rigidity comparable to conventional tunnel boxes armed with a stiffening frame. Its manufacturing cost is also comparable to tunnel boxes known from the state of the art.
