Abstract

PCT No. PCT/FR89/00041 Sec. 371 Date Dec. 10, 1990 Sec. 102(e) Date Dec. 10, 1990 PCT Filed Feb. 3, 1989 PCT Pub. No. WO89/07174 PCT Pub. Date Aug. 10, 1989.This invention relates to a device for fastening a guy to a concrete bridge deck. A metal plate is abutted against the horizontal surface of the deck and retained there with pre-stressing cables at its top surface and an extension which protrudes downward into the deck from its bottom surface. An anchoring device is mounted on the upper surface of the plate. It may be positioned to keep the guy in a plane parallel to the plate and do not require that the cables pass through the deck. The deck may have spaced bearing surfaces that are angled and/or are parallel to one another and support anchoring devices that keep the cables running in different directions from one another.

Description

La présente invention est relative à un dispositif d'accrochage d'un hauban sur un tablier en béton d'un pont, en particulier d'un pont à haubanage dit "en éven­tail", dans lequel une série de haubans relie des points régulièrement espacés du tablier au sommet d'un pylône de support.The present invention relates to a device for attaching a stay cable to a concrete deck of a bridge, in particular a so-called "fan-shaped" cable-stayed bridge, in which a series of stay cables connects regularly spaced points. of the deck at the top of a support pylon.

Suivant la technique usuelle, la fixation d'un hauban au tablier se fait en prévoyant que le hauban tra­verse le tablier, généralement au niveau d'une membrure longitudinale, pour venir porter, sur la face opposée du tablier, des moyens de retenue d'extrémités, qui pren­nent appui sur cette face inférieure du tablier.According to the usual technique, the fixing of a shroud to the deck is done by providing that the shroud crosses the deck, generally at the level of a longitudinal member, to come to carry, on the opposite face of the deck, retaining means for ends, which bear on this underside of the deck.

Lorsque le tablier est en béton armé, la présence des tubes contenant les haubans, qui sont à des inclinai­sons qui varient régulièrement d'un bout à l'autre du pont, l'angle avec l'horizontale diminuant à mesure qu'on s'écarte du pylône, perturbe considérablement le dispositif de ferraillage, ce qui oblige à réaliser ce dernier avec un soin particulier, peu compatible avec une fabrication rapide, ou une préfabrication relativement industrielle.When the deck is made of reinforced concrete, the presence of the tubes containing the shrouds, which are at inclinations which vary regularly from one end to the other of the bridge, the angle with the horizontal decreasing as one s' away from the pylon, considerably disturbs the reinforcement device, which means that the latter must be made with particular care, not very compatible with rapid manufacturing, or relatively industrial prefabrication.

La présente invention a pour but de remédier à cet inconvénient, et de fournir un dispositif d'accrochage qui n'impose pas de modifier les plans de ferraillage au niveau de chaque accrochage du hauban, et permette par conséquent une construction plus rapide et moins su­jette à des risques d'erreurs.The object of the present invention is to remedy this drawback, and to provide a fastening device which does not require modification of the reinforcement planes at the level of each fastening of the stay cable, and consequently allows a faster and less prone construction. at risk of errors.

Pour obtenir ce résultat, l'invention fournit un dispositif d'accrochage d'un hauban sur un tablier en béton d'un pont, qui comprend :
- une plaque métallique dont une face est conçue pour venir contre une surface plane d'appui du tablier, cette face portant au moins un saillant apte à pénétrer dans une cavité du tablier pour empêcher un glissement relatif de la plaque et de ladite surface plane d'appui,
- des moyens d'accrochage de l'extrémité du hauban, ces moyens étant portés par des ferrures solidaires de la face de la plaque opposée à celle qui est conçue pour venir en appui contre le tablier, et
- des câbles ou tirants de précontrainte, aptes à maintenir la plaque en appui contre la surface plane du tablier, ces câbles ou tirants prenant appui sur le côté du tablier opposé à celui qui porte ladite surface plane.To obtain this result, the invention provides a device for hanging a stay cable on a concrete deck of a bridge, which comprises:
- A metal plate, one face of which is designed to come against a flat support surface of the apron, this face carrying at least one projection capable of penetrating into a cavity of the apron to prevent relative sliding of the plate and of said flat surface d 'support,
means for hooking the end of the stay, these means being carried by fittings integral with the face of the plate opposite to that which is designed to come into abutment against the deck, and
- prestressing cables or tie rods, capable of holding the plate in abutment against the flat surface of the deck, these cables or tie rods bearing on the side of the deck opposite to that which carries said flat surface.

De préférence, le saillant et/ou la cavité ont une forme de révolution autour d'un axe perpendiculaire au plan de la plaque de la surface plane d'appui, pour permettre l'orientation du dispositif en fonction de la direction du hauban.Preferably, the protrusion and / or the cavity have a shape of revolution around an axis perpendicular to the plane of the plate of the planar support surface, to allow the orientation of the device as a function of the direction of the shroud.

Suivant une réalisation avantageuse, le saillant contient les moyens de retenue d'un desdits câbles ou tirants de précontrainte.According to an advantageous embodiment, the projection contains the means for retaining one of said cables or prestressing tie rods.

Suivant une première forme de réalisation, les moyens d'accrochage sont prévus pour permettre de maintenir le hauban avec une inclinaison non nulle par rapport à la plaque. Cette disposition s'applique avantageusement si l'on prévoit que ladite surface plane d'appui du tablier est une surface horizontale, et que les câbles ou tirants de précontrainte traversent le tablier vers le bas pour venir prendre appui sur une surface horizontale dirigée en sens opposé dudit tablier.According to a first embodiment, the attachment means are provided to allow the stay to be maintained with a non-zero inclination relative to the plate. This arrangement applies advantageously if it is provided that said flat bearing surface of the deck is a horizontal surface, and that the cables or tie rods of prestressing cross the deck down to come to bear on a horizontal surface directed in the direction opposite of said apron.

Suivant un autre mode d'exécution, les moyens d'ancrage sont prévus pour permettre de maintenir le hauban dans un plan parallèle à celui de la plaque. Cette deuxième modalité est particulièrement avantageuse si l'on prévoit que la surface plane d'appui du tablier est portée par un des bords du tablier, et présente avec la verticale le même angle que la nappe dont fait partie le hauban que le dispositif doit maintenir, et le câble ou tirant de précontrainte traverse le tablier suivant une direction transversale et à peu près horizontale dans son ensemble.According to another embodiment, the anchoring means are provided to allow the stay to be held in a plane parallel to that of the plate. This second modality is particularly advantageous if it is provided that the flat bearing surface of the deck is carried by one of the edges of the deck, and has with the vertical the same angle as the sheet of which the shroud which the device must maintain , and the cable or prestressing tie crosses the deck in a transverse direction and approximately horizontal as a whole.

L'invention fournit encore un pont haubané équipé de dispositifs tels que décrits ci-dessus, et qui présente pour particularité que le tablier porte, à intervalles réguliers, des surfaces planes d'appui, orientées parallè­lement les unes aux autres, et ces surfaces planes d'appui supportent des dispositifs d'accrochage qui maintiennent les câbles avec des directions différentes de l'un à l'autre.The invention also provides a cable-stayed bridge equipped with devices as described above, and which has the particularity that the deck carries, at regular intervals, flat bearing surfaces, oriented parallel to each other, and these flat surfaces support supports hooking devices that hold cables with different directions from one to the other.

L'invention va maintenant être exposée de façon plus détaillée à l'aide d'exemple pratiques, illustrés à l'aide des dessins, parmi lesquels :

La figure 1 montre un pont, dont le tablier 1 repose à une extrémité sur des culées 2, et est soutenu par des haubans 3, qui relient des points successifs du tablier avec le sommet 4 de pylône 5 monté sur des piles 6, qui reposent sur le sol 7.Figure 1 shows a bridge, whose deck 1 rests at one end on abutments 2, and is supported by guy lines 3, which connect successive points of the deck with the top 4 of pylon 5 mounted on piers 6, which rest on the ground 7.

A la figure 2, on voit un dispositif d'accrochage selon l'invention monté sur la face supérieure, horizonta­le, d'un tablier 1.In FIG. 2, a hooking device according to the invention is seen mounted on the upper, horizontal face of an apron 1.

Le dispositif comprend une plaque 10, qui porte à sa partie inférieure un saillant tronconique 11, qui pénètre dans une cavité correspondante de la face supé­rieure du tablier 1. Sur la face supérieure de la plaque 10, des fers 12, 13, à section en T, sont fixés obliquement sur ladite plaque 11, leur direction générale faisant avec l'horizontale un angle égal à celui du hauban 3 que le dispositif est destiné à retenir. Une pièce d'accrochage 14, soudée aux fers 12 et 13, est traversée par l'extrémité du hauban 3, qui prend appui sur cette pièce 14 par l'intermédiaire d'une pièce terminale 15. Des tirants de précontrainte 16 traversent toute l'épaisseur du tablier 11, et, grâce à des vis 17, 18, serrent fortement la plaque 10 contre le tablier. Les efforts de traction exercés par le hauban 3 peuvent se décomposer en une composante verticale, qui est reprise par les tirants 16, et une composante horizontale, qui est transmise au tablier par le saillant 11 et par le frottement de la plaque 10 contre la surface horizontale d'appui prévue sur le tablier.The device comprises a plate 10, which carries at its lower part a frustoconical projection 11, which penetrates into a corresponding cavity of the upper face of the deck 1. On the upper face of the plate 10, irons 12, 13, with cross-section T, are fixed obliquely on said plate 11, their general direction making with the horizontal an angle equal to that of the shroud 3 that the device is intended to retain. A hooking piece 14, welded to the irons 12 and 13, is crossed by the end of the stay 3, which bears on this piece 14 via a terminal piece 15. Prestressing tie rods 16 pass through the whole 'thickness of the apron 11, and, thanks to screws 17, 18, strongly tighten the plate 10 against the apron. The tensile forces exerted by the shroud 3 can be broken down into a vertical component, which is taken up by the tie rods 16, and a horizontal component, which is transmitted to the deck by the projection 11 and by the friction of the plate 10 against the surface. horizontal support provided on the deck.

Les figures 5 à 8 montrent une autre forme de réalisation. Le tablier présente, sur son bord extérieur, ou rive, une surface d'appui 20, orientée longitudinale­ment, et un peu oblique par rapport à la verticale. La surface d'appui 20 est, dans l'ensemble, circulaire. Le tablier 1 étant relativement mince, il présente une suré­paisseur 21 pour recevoir cette surface d'appui. Le dispo­sitif d'accrochage proprement dit comprend une plaque 22, de forme circulaire, qui vient en appui sur la surface 20, et porte à sa partie tournée vers le tablier, une saillie tronconique 23 qui est creuse et vient se loger dans une cavité également tronconique 24 prévu au centre de la surface d'appui 20. Sur sa face opposée à la saillie 23, la plaque 22 porte des ferrures constituées de deux fers plats 25, identiques, disposées perpendiculairement à la plaque 20, et formant entre-elles une sorte de chape, entre lesquels vient se loger une pièce de support 26, contre laquelle porte une pièce d'extrémité 27 solidaire du hauban 3. La saillie creuse 23 sert de logement à la tête d'ancrage d'un câble de précontrainte 28, qui pénètre à l'intérieur du tablier 1 par un passage oblique, perpen­diculaire au plan de la surface 20. Ce câble s'incurve ensuite pour devenir horizontal et traverse toute la lar­geur du tablier, pour venir s'ancrer sur un dispositif analogue situé sur la rive opposée du tablier.Figures 5 to 8 show another embodiment. The deck has, on its outer edge, or shore, a bearing surface 20, oriented longitudinally, and a little oblique with respect to the vertical. The bearing surface 20 is, on the whole, circular. The deck 1 being relatively thin, it has an extra thickness 21 to receive this bearing surface. The attachment device proper comprises a plate 22, of circular shape, which comes to bear on the surface 20, and carries, in its part facing the deck, a frustoconical projection 23 which is hollow and is housed in a cavity also frusto-conical 24 provided in the center of the bearing surface 20. On its face opposite to the projection 23, the plate 22 carries fittings constituted by two flat bars 25, identical, arranged perpendicular to the plate 20, and forming between them a sort of yoke, between which is housed a support piece 26, against which carries an end piece 27 integral with the shroud 3. The hollow projection 23 serves as a housing for the anchoring head of a prestressing cable 28, which penetrates inside the deck 1 by an oblique passage, perpendicular to the plane of the surface 20. This cable then bends to become horizontal and crosses the entire width of the deck, to be anchored on a similar device located on the oppo shore the apron.

On conçoit que, pour mettre en place les haubans, il faut orienter le dispositif par pivotement de la plaque autour de l'axe de la cavité 24, jusqu'à l'amener dans la bonne direction. L'inclinaison des surfaces 20 par rapport à l'horizontale est celle de tous les haubans de la même nappe de câbles qui soutiennent le bord du tablier. Il suffit, par conséquent, lors de la construction du pont, de prévoir sur le tablier des surfaces d'appui 20 identiques les unes aux autres, aux emplacements prévus, et d'orienter à chaque fois la plaque 22 pour obtenir un alignement parfait du dispositif d'accrochage avec les câbles.It is understood that, to set up the shrouds, the device must be oriented by pivoting the plate around the axis of the cavity 24, until it is brought in the right direction. The inclination of the surfaces 20 relative to the horizontal is that of all the shrouds of the same layer of cables which support the edge of the deck. It is therefore sufficient, during the construction of the bridge, to provide on the deck support surfaces 20 identical to each other, at the locations provided, and to orient each time the plate 22 to obtain perfect alignment of the hanging device with cables.

Avec la disposition des figures 2 à 4, il est nécessaire de prévoir que l'orientation des ferrures 12 et 13 est modifiée pour chaque point d'accrochage. Cette complication est compensée par le fait qu'il n'est pas nécessaire d'avoir un câble de précontrainte traversant tout le tablier. Il est d'ailleurs possible de prévoir entre les ferrures 12 et 13 et la pièce d'accrochage 14, une liaison articulée, ce qui permet à ce moment là, au moins dans certaines limites, d'utiliser la même pièce pour un certain nombre de haubans.With the arrangement of Figures 2 to 4, it is necessary to provide that the orientation of the fittings 12 and 13 is modified for each attachment point. This complication is compensated by the fact that it is not necessary to have a prestressing cable crossing the entire deck. It is also possible to provide between the fittings 12 and 13 and the attachment part 14, an articulated connection, which allows at this time there, at least within certain limits, to use the same part for a certain number guy lines.
