Pont de liaison enjambant un fossé de bord de route
La présente invention concerne un pont de liaison enjambant un fossé de bord de route.Connecting bridge spanning a roadside ditch
The present invention relates to a connecting bridge spanning a roadside ditch.
I1 est connu de disposer de petits transformateurs sur des poteaux électriques, cela arrive fréquemment à la campagne. Lorsqu'un transformateur est ainsi accroché en haut d'un poteau électrique, il est relié à un sectionneur situé plus bas sur le poteau de façon à etre accessible pour etre manoeuvré par un homme situé au pied du poteau. I1 is known to have small transformers on electric poles, this often happens in the countryside. When a transformer is thus hung at the top of an electrical pole, it is connected to a disconnector located lower on the pole so as to be accessible to be operated by a man located at the foot of the pole.
Les poteaux électriques situés sur le bas côté d'une route sont généralement séparés de la chaussée par un fossé. Ainsi lorsqu'un poteau porte un tel sectionneur, il existe un petit pont enjambant le fossé et permettant d'atteindre facilement le poteau pour permettre d'actionner le sectionneur. Electricity poles located on the side of a road are generally separated from the road by a ditch. Thus when a post carries such a disconnector, there is a small bridge spanning the ditch and making it easy to reach the post to allow the disconnector to be actuated.
Cependant, un tel pont gêne le passage des machines à entretenir les fossés, en outre, ces ponts en béton constituent des obstacles solides, dangereux pour les véhicules. However, such a bridge hinders the passage of machines for maintaining ditches, in addition, these concrete bridges constitute solid obstacles, dangerous for vehicles.
La présente invention a pour but de pallier ces inconvénients et elle a pour objet un pont de liaison enjambant un fossé de bord de route, caractérisé en ce qu'il comprend une passerelle légère articulée à l'une de ses extrémités autour d'un axe horizontal entre deux ailes verticales d'une ferrure servant de charnière et scellée sur un petit massif de béton situé de l'autre cté du fossé par rapport à la chaussée de la route. The present invention aims to overcome these drawbacks and it relates to a connecting bridge spanning a roadside ditch, characterized in that it comprises a light bridge hinged at one of its ends around an axis horizontal between two vertical wings of a fitting serving as a hinge and sealed on a small concrete block located on the other side of the ditch in relation to the road pavement.
Selon une réalisation particulière, ladite passerelle est munie sur l'un de ses côtés longitudinaux d'un ergot, l'aile de ladite ferrure, située du côté de cet ergot possédant un trou oblong pour le passage avec jeu d'un axe charnière, l'extrémité supérieure de ladite aile comportant une encoche dans laquelle peut venir se placer ledit ergot, maintenant la passerelle dans une position verticale. According to a particular embodiment, said gangway is provided on one of its longitudinal sides with a lug, the wing of said fitting, situated on the side of this lug having an oblong hole for the passage with play of a hinge axis, the upper end of said wing having a notch in which said lug can be placed, maintaining the gangway in a vertical position.
L'invention sera bien comprise à la lumière de la description d'un exemple particulier de réalisation de l'invention, faite ci-après en regard du dessin annexé dans lequel
La figure 1 est une vue en perspective d'un pont de liaison selon l'invention.The invention will be clearly understood in the light of the description of a particular embodiment of the invention, given below with reference to the appended drawing in which
Figure 1 is a perspective view of a connecting bridge according to the invention.
La figure 2 est une vue partielle en coupe selon II-II de la figure 1. FIG. 2 is a partial sectional view along II-II of FIG. 1.
La figure 3 est une vue partielle en élévation du pont de liaison selon l'invention. Figure 3 is a partial elevational view of the connecting bridge according to the invention.
La figure 4 est une vue de gauche selon IV-IV de la figure 3. Figure 4 is a left view along IV-IV of Figure 3.
La figure 5 est une vue de droite selon V-V de la figure 4. Figure 5 is a right view along V-V of Figure 4.
La figure 6 est une vue agrandie du détail repéré VI sur la figure 3. FIG. 6 is an enlarged view of the detail marked VI in FIG. 3.
En se reportant à la figure 1, on voit un fossé 1 qui borde la chaussée d'une route 2. De l'autre cté du fossé 1 par rapport à la route 2 se trouve un petit massif support en béton 3 sur lequel est scellée une ferrure 4 comportant deux ailes latérales verticales 5 et 6 entre lesquelles est articulée une passerelle légère 7. Referring to Figure 1, we see a ditch 1 which borders the roadway of a road 2. On the other side of the ditch 1 relative to road 2 is a small solid concrete support 3 on which is sealed a fitting 4 comprising two vertical lateral wings 5 and 6 between which a light gangway 7 is articulated.
Cette passerelle est par exemple réalisée en polyester renforcé de tissus de fibre de verre et comporte des nervures de renforts 8 réalisées par des armatures 9 en matériaux stratifiés (figure 2) placées entre deux couches successives de tissus de fibres de verre imprégné de polyester. La ferrure 4 est réalisée en acier galvanisé. This gateway is for example made of polyester reinforced with fiberglass fabrics and has reinforcing ribs 8 made by frames 9 of laminated materials (Figure 2) placed between two successive layers of fiberglass fabrics impregnated with polyester. The fitting 4 is made of galvanized steel.
La figure 2 montre le profil de la passerelle. La passerelle peut ainsi pivoter autour d'un axe horizontal entre les deux ailes 5 et 6 de la ferrure 4. Figure 2 shows the profile of the gateway. The bridge can thus pivot around a horizontal axis between the two wings 5 and 6 of the fitting 4.
Dans sa position habituelle, la passerelle est à l'horizontale, son extrémité reposant de l'autre cté du fossé sur une semelle 10 en béton. In its usual position, the walkway is horizontal, its end resting on the other side of the ditch on a concrete sole 10.
Ainsi, cette passerelle, placée à côté d'un pylône électrique, non représenté, porteur d'un sectionneur, permet facilement à un agent d'accéder à ce sectionneur pour le manoeuvrer.Thus, this gateway, placed next to an electric pylon, not shown, carrying a disconnector, easily allows an agent to access this disconnector to maneuver it.
Lorsque cela est nécessaire pour l'entretien du fossé, par exemple pour le curer ou faucher l'herbe qui y pousse et cela à l'aide d'une machine, on fait pivoter la passerelle autour de son axe et on la fait reposer contre le poteau s'il se trouve derrière, ou, s il se trouve non pas derrière, mais sur le côté, contre un éventuel obstacle : arbuste, haie, etc... ou tout simplement sur le sol par pivotement complet de 1800. When it is necessary for the maintenance of the ditch, for example to clean it or mow the grass which grows there and that using a machine, one makes pivot the footbridge around its axis and one makes it rest against the post if it is behind, or, if it is not behind, but on the side, against a possible obstacle: shrub, hedge, etc ... or simply on the ground by full pivoting of 1800.
On peut également, comme c'est le cas dans l'exemple représenté sur les figures, prévoir un aménagement permettant le maintien vertical de la passerelle. It is also possible, as is the case in the example shown in the figures, to provide an arrangement allowing the vertical maintenance of the bridge.
A cet effet, l'aile 6 de la ferrure 4 comporte à son extrémité supérieure, une encoche 11 et le passage pour l'axe d'articulation est constitué par un trou oblong 12 ; Ceci permet, ayant relevé la passerelle dans la position verticale, telle que représenté en pointillés sur la figure 1, et en appuyant sur le côté de la passerelle, selon la flèche x, de soulever légèrement ce cté de la passerelle comme le montre la flèche Y et d'introduire un ergot 13, porté par la passerelle sur ce même côté longitudinal, dans l'encoche 11 et de maintenir ainsi la passerelle dans la position- verticale. For this purpose, the wing 6 of the fitting 4 has at its upper end, a notch 11 and the passage for the hinge pin is constituted by an oblong hole 12; This allows, having raised the gangway in the vertical position, as shown in dotted lines in FIG. 1, and by pressing on the side of the gangway, according to arrow x, to slightly lift this side of the gangway as shown by the arrow Y and introduce a lug 13, carried by the bridge on this same longitudinal side, into the notch 11 and thus maintain the bridge in the vertical position.
Les figures suivantes, 3 à 6, montrent les détails de réalisation des axes d'articulation, de l'ergot 13 et de l'ancrage de la ferrure 4 sur le support 3. The following figures, 3 to 6, show the details of embodiment of the articulation axes, of the lug 13 and of the anchoring of the fitting 4 on the support 3.
La figure 3 montre le massif support 3 dans lequel a été noyé un fer rond d'ancrage 14 sur lequel ont été soudées deux vis 15 et 16, dont les extrémités dépassent le niveau du massif support 3. La ferrure support 3 est fixée sur ces vis 15 et 16 au moyen d'écrous 17 et 18. FIG. 3 shows the support solid 3 in which a round anchoring iron 14 has been embedded, on which two screws 15 and 16 have been welded, the ends of which exceed the level of the support solid 3. The support fitting 3 is fixed on these screws 15 and 16 by means of nuts 17 and 18.
L'aile 5 du support 4 reçoit l'articulation 19 et l'aile 6 l'articulation 20. The wing 5 of the support 4 receives the articulation 19 and the wing 6 the articulation 20.
Ces articulations 19 et 20, ainsi que l'ergot 13 sont réalisés de la même façon, et la figure 6 en montre le détail de réalisation. These joints 19 and 20, as well as the lug 13 are made in the same way, and Figure 6 shows the detail of embodiment.
A l'emplacement de chacun de ces organes (19, 20 et 13) est prévu sur la passerelle 7 un bossage 21 à l'intérieur duquel est placé un insert d'articulation 22 dans lequel on vient visser une vis 23 à tête hexagonale 24 venant se serrer contre une entretoise 25. At the location of each of these members (19, 20 and 13) is provided on the bridge 7 a boss 21 inside which is placed a hinge insert 22 in which a screw 23 with a hexagonal head 24 is screwed coming to clamp against a spacer 25.
Enfin, un câble de sécurité 26 (figure 1), fixé à une nervure 8, relie la passerelle au massif support 3. Finally, a safety cable 26 (FIG. 1), fixed to a rib 8, connects the gangway to the solid support 3.
Les inserts d'articulation 22 des articulations 19 et 20 sont calculés pour se rompre en cas de choc provoqué par un véhicule routier. The articulation inserts 22 of the articulations 19 and 20 are calculated to rupture in the event of an impact caused by a road vehicle.
Par contre, le câble de sécurité 26 est choisi suffisamment résistant (résistance de 1400 kg par exemple) pour que la passerelle, désolidarisée de sa ferrure 4, ne puisse pas etre projetée alentour. On the other hand, the safety cable 26 is chosen to be strong enough (resistance of 1400 kg for example) so that the gangway, detached from its fitting 4, cannot be thrown around.
