    Description [0001] The present invention relates to a fastening system for viaduct cables, such as for example railway highway viaducts or bridges in general.
    [0002] It is known that motorway structures can also be used for the transport of cables, for example electric ones, even at high voltage, which are fixed to the sides of the roadway or in general in the vicinity of the same.
    [0003] In the portions of the motorway structures that present viaducts the cables are anchored to the sides of the spans by fixing them by means of brackets or similar elements. It is known that viaducts or bridges are structures that move both due to thermal effects and due to seismic stresses. The cables associated with it undergo significant deformations and displacements depending on the cable connection system to the viaduct. In viaducts of considerable size, the movements can also be of the order of 60 cm-1 m, in such cases the cable can also be damaged / broken if it is rigidly connected to the structure of the viaduct.
    [0004] The present invention relates to a technical solution for supporting cables in the viaduct sections such as to allow deformations and movements of the viaduct itself without inducing dangerous and undesired stresses on the cable. An aspect of the present invention relates to a fastening system for cables with bridge viaducts or the like, having the characteristics of the attached claim 1. The characteristics and advantages of the system according to the present invention will be better understood and clearer from the following description, by way of non-limiting example , of an embodiment with reference to the attached figures which illustrate respectively: • fig. 1a shows in a schematic side view a motorway viaduct to which a side wall cable is associated by means of the system of the present invention; • fig. 1b shows a schematic plan view of a motorway viaduct to which a cable is associated from the inside to the outside of the deck section through the system of the present invention; • fig. 2 shows a front view of a portion of the viaduct which shows a connecting element of the system according to the present invention; • fig. 3 shows the connection element of fig. 2; • fig. 4a and 4b show in a side view the portion of the viaduct which shows a connecting element of the system according to the present invention, at rest and at an angle respectively due to an oscillation; • fig. 5 shows a portion of connection between the tubes of the system according to the present invention which contain the cable.
    [0005] With reference to the above figures, the system of the present invention comprises a guide 2 longitudinally constrained to the viaduct, a plurality of connection elements to which the cable C is associated and which run along this guide. These connecting elements comprise at least one carriage 3 able to slide in this guide, at least one tubular structure 4, in which the cable is slidably inserted and an articulated structure 5 interposed between the carriage and the tube which allows the rotation of the tubular structure with respect to the cart around the three axes X, Y and Z orthogonal to each other.
    [0006] In the embodiment illustrated in fig. 1a schematically illustrates a viaduct V linked to supports for the beginning of the SI and the end SF of the viaduct itself. Along the viaduct are fixed two cables C through the system of the present invention which provides the guide 2 on which connection elements run substantially equidistant from each other, so as to optimally distribute the weight of the cables.
    [0007] Fig. 2 illustrates in particular the structure of the guide 2 and of the connecting element 3.
    [0008] In particular, the guide 2 is preferably shaped in a double section "T" and is preferably fixed to the viaduct by at least one pair of metal sections P.
    [0009] In each loop of these «T» there are inserted wheels 31 of the carriage 3 which allow their longitudinal sliding.
    [0010] Below the carriage 3 there is the articulated structure comprising a first articulation 51 able to allow rotation about a vertical axis Y, a second articulation able to allow rotation about a horizontal axis X and a third joint suitable to allow the rotation around a horizontal axis Z, orthogonal to this horizontal axis X. The tubular structure 4 is constrained below the third joint and comprises a frame formed by a central support bar 41 which supports at least one base 42 on which pipes 43 rest. In the case shown there are two superimposed bases, clearly the number of bases can vary depending on the number of tubes and cables to be supported. The tubes are advantageously arranged one on each side of the central bar to give greater balance to the system. At least one cable runs inside each tube C. Each base can be advantageously covered by a casing 44 able to keep the tubes in position 43.

    Claims (10)
    [1]
    [0011] In this way the system provides that the cable supports are completely released from the viaduct in the longitudinal direction. This degree of freedom allows the work to translate and undergo thermal deformations in this direction without dragging the cable during this movement. This is allowed by a pair of carriage bearings that slide on the lower wing of the double T guide 2 anchored to the viaduct. [0012] To ensure the smooth sliding of all the carriages, avoiding that this function is left to the cables, the carriages themselves will be connected to each other by a FA steel cable that will be blocked on the shoulders of the viaduct near the backfills of the cables themselves. This rope also has the function of earthing the trolleys. [0013] The first articulation 51 allows the rotation around the vertical axis Y. This degree of freedom allows the constraint to absorb planimetric variations of the path of the cables. An example is constituted by the situations in which the cables pass from the inside to the outside of the viaduct girder. The second joint 52 allows the rotation around the horizontal axis X. This degree of freedom allows the constraint to orientate itself vertically, offering cables a transverse fixing situation that is always flat, regardless of the local transverse slope of the bridge or viaduct. The third joint 53 allows the rotation around the transversal axis Z. This last degree of freedom has the purpose of allowing the constraint movements that allow to absorb local thermal variations of the cable-counter-tube system. [0014] Possible local thermal deformations of the hollow system of the tubular structure 4 are absorbed by a slight longitudinal clearance deliberately left at each individual anchorage and by the possibility that the cable extends locally exploiting the many movements and the many rotations allowed. In particular, the second articulation 52 comprises a pin 521 which is inserted in a slot 522 with a diameter greater than that of the pin, which determines such play. [0015] In addition to the degrees of freedom permitted by the system indicated above, the tubes 43 are not continuous along the entire length of the viaduct but are lengths that are joined together by means of holding sleeves 45 which will make it possible to compensate for the elongation due to thermal variations. Advantageously, the tubes 43 are made of HDPE (high density polyethylene). The cable support system bases its operating principle on the idea of allowing the viaduct all the movements necessary for its correct behavior during operation and in the seismic phase. In the proposed solution, each supporting element can slide freely with respect to the viaduct, making movements in space according to the degrees of freedom allowed to the same constraint. [0016] In both installations of figs. 1a and 1b, since these are metallic structures exposed to corrosive agents, it is envisaged to use stainless steel profiles and connecting elements for the guides, which guarantees rust resistance for very long periods and, given the unassailable nature of natural and chemical agents , a very low maintenance and guarantee of efficiency over the years. claims
