Like. In the course of roads or paths, ie to overcome relatively short obstacles with lengths up to z. B. 20 m. Previous bridge structures for this purpose are relatively difficult, provided that their individual parts of conventional components and not at the expense of high costs od with carbon fibers. Like. Reinforced lightweight plastics, light metals such as titanium od. Like. Are made. A mere reduction of the material thicknesses are limited because of the then existing buckling, buckling and tilting tendency.

  • a molded piece 5 according to the invention preferably has a trapezoidal cross-section.
  • the molded piece 5 which is shown slightly enlarged in comparison with FIGS. 1 to 4, has a shape and size such that it fits exactly into the receptacle 4. It therefore contains a flat upper side 5a, whose width corresponds to the width of the inner surface of the central web 1b, a flat bottom 5b, the width of which substantially corresponds to the distance between the two side webs 1a, and a substantially corresponding to the height of the recess 4 corresponding thickness of z. B. 26 mm.
  • the thickness of the fitting 5 may also be slightly larger than the height of the receptacle 4 corresponds.
  • the upper side 5a is also connected to the underside 5b by inclined surfaces 5c, which are preferably arranged at the same angles to the sides 5a, 5b, as are the transitional sections 1c of the sheet 1 relative to their side and middle webs 1a, 1b.
  • the length of the fittings 5 is chosen so that they allow the fixings described below,
  • Fig. 7 and 8 show a tube 6 with rectangular cross-section, which has a length of z. B. 2200 mm as a post and with a length of z. B. about 2900 mm can be used as a diagonal for the bridge to be described.

  • This consists of two mutually parallel sheets 1, which are spaced from each other by at least one arranged between these, consisting of a tube 6 post 8.
  • the lower flange 7 is preferably horizontal and the post 8 is arranged vertically, although the bridge as a whole could also be arranged obliquely.
  • the firm connection of the two sheets 1 of the lower chord 7 is obtained by means of the posts 8 and with the help of only schematically indicated, the post 8 and the side bars 1a of the sheets 1 passing through screws 9 and these nuts are turned up.
  • FIG. 13 and 14 show a preferred embodiment and attachment of a cross member 14 on a lower flange 7.
  • the cross member 14 is composed analogously to the lower flange 7 of two sheets 1, wherein the openings of the receptacles 4 facing each other (Fig. 14).
  • the mounting of the cross member 14 is carried out by means of posts 8, which are arranged between the two sheets 1 and connected to the side bars 1a by further screws 15, which protrude through the tubes 8 and the side bars 1a of the sheets 1 and secured with nuts, not shown are.
  • the upper chords of a bridge to be described are made as the lower chords 7 of the sheets 1 and connected as the lower chords 7 with the diagonal 10 and / or the post 8, so that a re-description of these compounds is not required.
  • a bridge already with the parts described with reference to FIGS. 1 to 8 and 11 to 14, ie without the posts 8.
  • a disc formed from the lower straps 7, corresponding upper straps and the diagonals 10 is then formed in the manner of a so-called strut framework, in which the diagonals 10 extend in a zigzag pattern between the lower and upper straps.
  • the posts 8 are additionally used to provide a post truss, at the between each two diagonal 10 a post 8 is installed.
  • each post 8 is preferably fixedly provided with two form pieces 5 already before the assembly of a bridge, which are arranged transversely to its axis.
  • the fittings 5 are alternately secured to the lower and upper ends of the posts 8, as indicated in Fig. 15 and 16.
  • each post 8 is provided in each case on two diametrically opposite sides of the rectangle and in each case with a shaped piece 5, that sufficiently long sections 5d and 5e of the shaped pieces 5 are provided to the right and left of the posts 8, in order to form the diagonals 10 in FIG. 11 way to connect.
  • the attachment of the diagonal 10 can be carried out with the aid of a fitting 5, which is fixed at the upper end of a post 8 as shown in FIG. 16.
  • Fig. 17 also shows the connection of two successive lower belts 7a and 7b in the longitudinal direction 2.
  • the two are facing each other Ends of the lower chords 7a and 7b respectively along a median plane 16 of the posts 8 against each other and then connected in the manner described with reference to FIGS. 9 and 10 with screws 9a and 9b to the post 8.
  • the attachment can therefore take place in the joint area at least partially through the fittings 5 therethrough
  • Fig. 18 shows a lightweight construction piece made from the described parts. It contains two spaced apart in the distance of the cross member 14 parallel discs, on the one hand a plurality of longitudinally 2 arranged in succession, according to Fig. 17 by means of posts 8 interconnected lower straps 7 and on the other hand a plurality of appropriately trained and arranged upper straps 17 which with a the distance of the post 8 corresponding distance are arranged in parallel above the lower chords 7.
  • each disc includes five bottom straps 7 and four top straps 17, nine posts 8 and ten diagonals 10, and both discs are interconnected by eleven cross members 14, two of which are formed as end brackets 14a.
  • the lower and upper straps 7 and 17 and the cross members 14, 14a are each formed from two opposing sheets 1 according to FIGS. 1 to 3 (see also FIGS. 9 to 14), which with the aid of the shaped pieces 5 according to FIGS. 4 to 6 are everywhere stiffened where the diagonal 10 or provided with the fittings 5 posts 8 are connected.
  • the fittings 5 as is the case in the best held for the embodiment, arranged in the direction of the main force introduction form-fitting in the receptacles 4, then also gives the essential advantage that at least the forces transmitted by the diagonal 10 forces predominantly on this Positive fit and not only on the bearing holes of the screw holes are transmitted to the lower and upper straps, which significantly increases the service life of the bridge.
  • no usual binding and gusset plates are required.
  • the z-axis of an imaginary coordinate system (FIG. 18) is understood as the direction of the main force introduction, whose x-axis is parallel to the longitudinal direction 2 of the bridge or the lower and upper belts 7, 17 and whose ⁇ -axis is parallel to the transverse beams 14 , 14a runs.
  • connection of the sheets 1, the fittings 5, the post 8 and the diagonal 10 takes place in the bridge of Fig. 18 in the manner described with reference to FIGS. 9 to 17.
