POUTRE DE REPRISE D'EFFORT POUR GRILLES DE VOIRIE.EXHAUST BEAM FOR ROAD GRILLS.
La présente invention concerne une poutre de reprise d'effort pour grilles de voirie. The present invention relates to a stress recovery beam for street gates.
II est connu de réaliser des grilles dont les barreaux parallèles peuvent être reliés par des barres de renfort inférieures et perpendiculaires aux barreaux. It is known to produce grids whose parallel bars can be connected by reinforcement bars below and perpendicular to the bars.
Les dites barres sont à poste fixe solidarisées par soudure ou tout autre 10 moyen aux barreaux. Généralement, ces grilles de voirie sont calculées pour résister à un effort normal. Said bars are fixed station secured by welding or other means to the bars. Generally, these road grids are calculated to withstand a normal effort.
C'est le cas notamment lorsque ces grilles sont réalisées en plusieurs éléments juxtaposés dans un cadre scellé au sol constitué d'un profilé en 15, cornière et qui ménagent en leur zone centrale un espace libre pour le passage d'un arbre. This is particularly the case when these grids are made of several elements juxtaposed in a sealed frame on the ground consisting of a profile 15, angle and which provide in their central area a free space for the passage of a tree.
Les efforts qu'elles ont à subir sont faibles. The efforts they have to undergo are weak.
II peut cependant arriver, lorsque l'espace urbain où elles sont utilisées comporte des emplacements de stationnement ou des voies de roulement, qu'elles aient à supporter le poids de véhicules, ce qui peut conduire à un affaissement de la grille par déformation. However, it may happen, when the urban space where they are used has parking locations or tracks, that they have to bear the weight of vehicles, which can lead to a depression of the grid by deformation.
II pourrait y être remédié en proposant soit des grilles spécialement renforcées directement d'usine, ce qui cependant compliquerait la fabrication et la pose par la nécessité de gérer des produits différents, soit en doublant la grille avec des structures d'appuis inférieures. It could be remedied by proposing either specially reinforced grids directly from the factory, which however would complicate the manufacture and installation by the need to manage different products, or by doubling the grid with lower support structures.
Par ailleurs, si le renforcement des.grilles peut-être envisagé facilement par la pose de pièces de supports transversales aux barreaux, la prise d'appui des pièces de renfort dans le cadre support de la grille n'est pas évident. Furthermore, if the reinforcement grilles can be envisaged easily by laying parts of transverse supports to the bars, the support of the reinforcing pieces in the support frame of the grid is not obvious.
D'autre part se pose le problème de la fixation à poste des dites pièces de renfort. On the other hand arises the problem of the fixing station said reinforcement pieces.
L'invention n'est pas limitée aux grilles à barreaux parallèles mais s'applique plus généralement à tout type de grille ou plaque de recouvrement et/ou de parement logée dans un cadre support comme par exemple des plaques en tôle perforée. The invention is not limited to parallel bars grids but more generally applies to any type of grid or cover plate and / or facing housed in a support frame such as perforated sheet metal plates.
La présente invention vise à obvier à ces inconvénients. The present invention aims to obviate these disadvantages.
À cet effet, la présente invention concerne une poutre de reprise d'effort pour grilles de voirie montée dans un cadre scellé au sol, constitué d'un profilé en cornière se caractérise essentiellement en ce qu'elle est constituée par une pièce de support horizontale indépendante de la grille elle-même de longueur inférieure à l'espacement interne entre deux cornières parallèles ou non du cadre formant surface d'appui, dont chacune des extrémités est dotée d'une platine transversale à la dite pièce support, repliée en partie haute à l'horizontale pour former une patte d'appui sur le cadre. To this end, the present invention relates to a force recovery beam for street gates mounted in a sealed frame on the ground, consisting of an angle profile is essentially characterized in that it is constituted by a horizontal support piece independent of the grid itself of length less than the internal spacing between two parallel or non-parallel angles of the bearing surface frame, each end of which is provided with a plate transverse to said support piece, folded in the upper part horizontally to form a support leg on the frame.
Suivant une autre- caractéristique de l'invention, la poutre de reprise d'effort est disposée sous les renforts de grilles inférieurs reliant les barreaux. According to another characteristic of the invention, the force recovery beam is arranged under the reinforcements of lower grids connecting the bars.
parallèles de la dite grille et les pattes d'appui sont dotées à leur sommet d'une encoche de passage du renfort de grille. parallel of said grid and the support legs are provided at their apex with a notch for passing the grid reinforcement.
Suivant encore une autre caractéristique de l'invention, la partie inférieure de chaque platine est inclinée en biais vers l'axe médian transversal de la poutre pour dégager le scellement du cadre. According to yet another characteristic of the invention, the lower part of each plate is inclined obliquely towards the transverse median axis of the beam to clear the sealing of the frame.
Suivant encore une autre caractéristique de l'invention, la pièce de support est constituée par un profilé en I avec une âme centrale et deux ailes supérieure et inférieure. According to yet another characteristic of the invention, the support piece is constituted by an I-section with a central core and two upper and lower wings.
5' D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description ci-après d'une forme de réalisation de l'invention donnée à titre d'exemple non limitatifs, et illustrée par les dessins joints dans-lesquels: - La figure 1 est une vue partielle d'une coupe, suivant un axe transversal aux barreaux, - La figure 2 est une vue en coupe partielle suivant un autre axe. 5 'Other advantages and characteristics of the invention will appear on reading the following description of an embodiment of the invention given by way of non-limiting example, and illustrated by the accompanying drawings in which FIG. 1 is a partial view of a section along an axis transverse to the bars; FIG. 2 is a partial sectional view along another axis.
Telle que représentée, l'invention concerne une poutre de reprise d'effort pour grilles de voirie. As shown, the invention relates to a stress recovery beam for street gates.
Suivant la forme de réalisation donnée à titre d'exemple, la grille est de type à barreaux 1 parallèles ou non reliés par des barres de renfort 2 inférieures, perpendiculaires aux dits barreaux 1. According to the embodiment given by way of example, the grid is of type 1 bars parallel or not connected by reinforcement bars 2 lower, perpendicular to said bars 1.
L'invention est cependant applicable sans sortir du cadre de l'invention à 20 tout type de grilles de préférences pourvues de renforts inférieurs 2. The invention is however applicable without departing from the scope of the invention to any type of preference gates provided with lower reinforcements 2.
La grille 1 est montée dans un cadre 3 scellé au sol, constitué par un ou des profilés en cornière.(surface d'appui). The grid 1 is mounted in a frame 3 sealed to the ground, consisting of one or more angles profiles (support surface).
De préférence la profondeur du cadre correspond à l'épaisseur de la grille 25 elle-même, barreaux 1 et renforts 2. Preferably the depth of the frame corresponds to the thickness of the grid 25 itself, bars 1 and reinforcements 2.
Avantageusement, le barreau de rive 1A de la grille a une hauteur égale à la dite épaisseur de la grille. Advantageously, the edge bar 1A of the grid has a height equal to the said thickness of the grid.
Avantageusement, la poutre selon l'invention est constituée par une pièce. support 4 de tout type adapté et qui est indépendante de la grille ellemême. Advantageously, the beam according to the invention consists of a part. support 4 of any suitable type and which is independent of the grid itself.
La longueur de la pièce support 4 est inférieure à l'espacement interne 5 entre deux cornières 3 parallèles au cadre. The length of the support piece 4 is less than the internal spacing 5 between two angles 3 parallel to the frame.
Chacune des extrémités de la pièce support est dotée d'une platine transversale 5 qui est repliée en partie haute 5A, à l'horizontale pour former les pattes d'appui sur le cadre. Each end of the support piece is provided with a transverse plate 5 which is folded at the top 5A, horizontally to form the support lugs on the frame.
La pièce de reprise. d'effort est disposée sous le ou les renfort(s) de grilles 2 et les pattes d'appui constituées par la partie repliée 5A de la platine 5, sont dotées d'une encoche 6 de passage du renfort de grille. The recovery room. of force is disposed under the or reinforcement (s) of grids 2 and the support legs formed by the folded portion 5A of the plate 5, are provided with a notch 6 for passage of the grid reinforcement.
La partie inférieure 5B de chaque platine 5, fixée à la pièce support 4 par tout moyen adapté, est inclinée en biais vers l'axe médian transversal de la poutre. The lower part 5B of each plate 5, fixed to the support piece 4 by any suitable means, is inclined at an angle towards the transverse central axis of the beam.
La poutre de reprise de l'invention est utilisable dans le cas ou les cornières définissant le cadre et les surfaces d'appui ne sont pas parallèles, 20 mais sont par exemple en arc de courbe. The recovery beam of the invention is usable in the case where the angles defining the frame and the bearing surfaces are not parallel, but are for example arc curve.
La conception de la poutre avec encoche 6 à chaque extrémité qui reçoit la barre 2 de renfort de grille a pour effet d'obtenir un autopositionnement de la poutre qui ne se déplacera pas latéralement. The design of the beam with notch 6 at each end which receives the bar 2 grid reinforcement has the effect of obtaining a self-positioning of the beam that will not move laterally.
La poutre 4 peut être constituée en tous matériaux adaptés, de préférence elle est constituée par un profilé métallique en I avec âme centrale 7, une aile supérieure 8 et une aile inférieure 9. The beam 4 can be made of any suitable material, preferably it consists of an I-shaped metal section with a central core 7, an upper flange 8 and a lower flange 9.
La poutre selon l'invention est utilisable pour tout type de grille ou plaque de recouvrement et/ou de parement logée dans un cadre support comme par exemple des plaques de tôle perforée. The beam according to the invention can be used for any type of grid or cover plate and / or facing housed in a support frame such as perforated sheet metal plates.
