Definitions

  • the present invention relates to a truss, and in particular to a truss which can be employed as a crossbar or portion of arc in the supporting structures of the movable coverings.
  • Known trusses comprise a pair of horizontal beams connected by means of a reticulated structure comprising a plurality of diagonal bars.
  • the beams and the diagonal bars are generally made up of metal sections welded to each other.
  • one or both beams include substantially rectangular metal sections whereby it is necessary to weld to the beams pairs of vertical metal plates or U-shaped portions of metal sections in order to contain laterally and to properly weld the ends of the diagonal bars, thus reinforcing the truss.
  • the welding of these reinforcing members to the beams obviously increases the manufacturing time and cost of the truss, while decreasing its aesthetic value.
  • the diagonal bars can be directly introduced and fixed therein, so that the truss according to the present invention can be obtained in a simple and resistant way without the help of said reinforcing members. Furthermore, with this arrangement, the diagonal bars can be simply cut at right angle, since their joint with the beams is carried out through the side walls, thereby reducing the surfaces to be mutually welded, with a consequent reduction of manufacturing times and costs.
  • Another advantage of the truss according to the present invention is its better aesthetic appearance thanks to the hiding of the ends of the diagonal bars.
  • the truss according to the present embodiment of the invention comprises in a known way a pair of beams 1 connected by means of a reticulated structure comprising a plurality of diagonal bars 2 arranged so as to form a series of triangular openings.
  • one or both beams 1 consist of metal sections which have a cross-section, for example with a substantially rectangular shape, with the surface 1 a facing the diagonal bars 2 provided with a longitudinal groove 1b having a substantially rectangular cross-section.
  • the width of groove 1b is substantially equal to the width of the diagonal bars 2, so that the ends of the latter can be introduced in groove 1b and easily fixed therein, in particular by means of weldings 3 or bolts passing through holes formed along axis 4.
  • the cross-section of the diagonal bars 2 is substantially rectangular, but it is clear that in other embodiments it could be different, e.g. U-shaped. Moreover, in this embodiment the angles between a diagonal bar 2 and the adjacent bars are substantially right, whereas the angles between bars 2 and beams 1 may change according to the specific strength requirements.
  • beams 1 could be not straight but rather curved, so that the resulting truss is also curved and can be used as a portion of a semicircular arc for coverings, for example of sports fields or protective coverings.
