Definitions

  • the invention relates to a gantry for spanning a road, for example in connection with the presentation of information to users of the road, which gantry comprises a lattice girder, which is constructed of at least one uppermost longitudinal element, a lowermost longitudinal element and lattice elements interconnecting these longitudinal elements, and, at each end of this lattice girder, a pair of upwardly converging legs.
  • Gantries of this kind are commonly known and are used for the attachment of billboards and/or traffic-lane signalling.
  • the known gantries are produced from steel and are consequently very heavy.
  • the fastening of the girder to the legs is labour-intensive, so that the installation of the gantry causes a great deal of traffic obstruction.
  • the object of the invention is to provide a gantry which does not have this drawback. This object is achieved by the fact that the uppermost longitudinal element passes over each pair of legs and is supported there by means of a bearing structure.
  • each pair of legs has, above the spot where they are fastened together, an outwardly protruding bearing structure, the width of which is approximately equal to the width of the uppermost longitudinal element.
  • the legs of each pair each have an obliquely upward running extension piece, directed away from the extension piece of the other leg, and the extremities of the extension pieces are each provided with a bearing structure for the uppermost longitudinal element.
  • the structure of the gantry according to the invention is particularly suitable for aluminium construction.
  • the uppermost longitudinal element comprises two parallel aluminium longitudinal profiles, which longitudinal profiles each possess a flat surface on their side facing the lattice elements.
  • the longitudinal profiles can possess two flat base surfaces, which, in transverse section, enclose an angle which is approximately equal to the complement of the base angle of the triangle, which base angle is determined by that longitudinal profile.
  • the lattice elements which can equally consist of aluminium tubes, then need to be obliquely pared in one direction only, thereby making the girder easier to produce.
  • Each longitudinal profile can further possess two flat side surfaces, which are each connected at right-angles to a base surface and are interconnected.
  • the support afforded to the girder can be made very stable if each bearing structure has an obliquely upward running flange, the side surfaces of the longitudinal profiles facing away from each other being shut in between the associated flanges at each end of the girder.
  • each longitudinal profile is interconnected by a curved surface and that curved surface is connected by means of an internal partition to both base surfaces.
  • a longitudinal profile which is made in this way is extremely resistant to the compression forces to which it is exposed; moreover, the internal partition helps the gradual transmission of forces between the longitudinal profile and the lattice elements.
  • each pair can each carry a U-shaped fastening piece, these fastening pieces being interconnected.
  • These fastening pieces can be identical and asymmetrical.
  • the legs and the fastening pieces can also be made of aluminium.
  • the legs comprise a plurality of interconnected longitudinal segments.
  • the gantry which is shown in Figure 1 comprises a girder 1 which is supported at both ends by a pair of legs 2, 3.
  • the girder comprises two uppermost longitudinal profiles 4, 5, a lowermost longitudinal profile 6 and lattice profiles 7 which interconnect these longitudinal profiles.
  • the legs 2, 3 comprise, on their mutually facing sides, a U-shaped stirrup 8, which stirrups are identical and are fastened together by a plurality of bolts 9.
  • the legs comprise extension pieces 10, 11 which are directed obliquely upward away from each other and on which the longitudinal profiles 4, 5 of the girder 1 are supported.
  • FIG. 4 illustrates the longitudinal profiles 4, 5, 6. These all comprise two flat base surfaces 12, 13, to which the lattice profiles 7 are welded. At the same time, they each comprise two flat side surfaces 14, 15, which are joined together by a curved surface 16. The curved surfaces are each connected by an internal partition 17 to the flat base surfaces 13, 14.
  • the legs are made up of longitudinal segments which are welded together by means of fastening strips 20, 21. These segments are also welded together at the site of the joints 22.
  • the lowermost longitudinal profile 6, in the variant of Fig. 3, supports a cable duct 18 by means of a flange 19.
  • the cable duct is provided with a cover 20, which can be swung open to one side.
  • the flange 19 has two strips 21 by which it is fixed to the lowermost longitudinal profile 6.
  • the duct 18 and flange 19 are likewise illustrated in Figure 3. Here it is also evident that the cables are able to be conducted downward via an elbow piece 22.
