Definitions

  • the invention relates to an assembly method for section-wise assembling and laying one out Items formed bridge, both sides of each one pointing upwards, preferably of half-timbering existing continuous beams, each Bridge section has at least one pair of support elements, that have both ends in the area of their lower chord each a cross member connectable by couplings and after coupling their top belts with the respective adjoining support element of the adjacent bridge section aligned and fixed opposite each other, and that between the cross beams this is supported by at least one slab extends, and to a composable by the method Bridge.
  • the invention has for its object an assembly method specify with which a bridge the entrance quickly and safely put together and can be relocated.
  • a bridge is to be created which can be put together using such a method.
  • the particular advantage of the method according to the invention is that the bridge as a result of fewer items can be assembled quickly and none for assembly Small parts are needed. A single plug and Swiveling movement already establishes a firm connection between the respective support element and the cross member forth.
  • the pods can be parts of the upper belt itself or upper belt connecting parts be.
  • two stem beams with at least one as a counterweight acting bridge section through the Obstacle advanced and on the other side embankment height-adjustable, then the bridge in time with their coupled sections with their Bottom belts on grooved feed rollers and advanced and supported on the stem supports Reaching the bridge end position using the height adjustment devices at the two ends of the stem is lowered to the floor.
  • the new assembly method can be inventively perform particularly advantageously with a bridge according to the features of claim 4, at of the couplings one each on the carrier element arranged arranged hammer head-like element, the a corresponding push-through opening of the cross member engages behind. This is a very simple way firm and secure connection created.
  • Another embodiment of the bridge provides that at least one of the arranged in the region of the cross member Sleeves with one that can be coupled to the cross member Provide pressure strut for the production of the triangular structure is. Sleeves present during construction save a special fastener in this way for the strut
  • Embodiment Another one according to the invention is particularly advantageous Embodiment in which a sleeve is so longitudinally displaceable is arranged that after connecting the encompasses both adjacent upper flange ends at the same time. In this way, a connection of the Top flange ends manufactured and only one pressure strut for the connection area needed. This is especially true for bridge training with single-walled beams.
  • a particularly advantageous embodiment of the new Bridge also consists of a bridge section a pair of support elements pointing approximately vertically upwards and the struts on the outside of the bridge are arranged. This also applies to one single-walled carrier design and has the advantage that the Struts don't hinder traffic.
  • the corresponding Designed cross beams can also be used for a bridge single-walled carrier design are used, and - at according to the same dimensions - even in exchange, e.g. B. as a replacement for the crossmember for the single-walled Execution can be used.
  • the cross member at least one at both ends by a Pipe piece formed cylindrical jacket-shaped projection have, which with the tubular lower chords or Lower belt parts of the carrier elements are aligned and themselves extending between these, these projections at the same time as tracks for appropriately shaped feed rolls be used.
  • cross beams in The longitudinal and transverse directions of the bridge are symmetrical are trained. This simplifies manufacture and Assembly in a special way.
  • each carrier element is only one Assigned sleeve with associated pressure strut.
  • the bridge is also provided that at least a part of the cross beams on their top with two symmetrical on both ends between the support elements arranged receiving means for fastening one each Roll frame is provided, the leadership of a Stem carrier serves. It is particularly advantageous that the receiving means alternatively for attaching a Schrammbords serve, and, in another inventive Design that the stem girder also as a scrap board is used. Stem girders or scrap board are advantageous box-shaped and in a known manner by putting together individual elements that the Lengths of the bridge sections are assigned, extendable.
  • Fig. 1 is a complete bridge section and a coupled part of a second bridge section shown, the two each formed from half-timbering Carrier elements 1 and several roadway plates 2 assigned are.
  • the roadway plates 2 extend side by side between cross beams 3, each in the longitudinal direction of the bridge between a pair of support elements are switched on or one end of the bridge form, as shown in the foreground of Fig. 1.
  • the right half of FIG. 1 shows the carrier element 1 in lying position after plugging together and before Coupling, which is done by swiveling upwards.
  • the Carrier elements 1 each have an upper chord 4 and a lower flange 5, which are tubular.
  • the ends of the top chords 4 are each from a sleeve 6 enclosed, to which a pressure strut 7 is welded, the other end at the associated end of the cross member 3 is coupled in the middle.
  • cross members 3 pieces of pipe 9 are incorporated, the same diameter as the lower chords 5 and two Have pair of disc halves 10, the push-through openings 11 for the hammer head-like elements 8 form.
  • the preferably formed from stiffened box profile Cross member 3 has on its two long sides between the pipe sections 9 each have a bar 12 on which support the ends of the carriageway slabs 2 so that their Align the upper sides with the upper side of the cross member 3.
  • Slider element 13 arranged so that the provided with a corresponding bore 14 end of assigned strut 7 in the closed central position is fixed.
  • the slide elements 13 can also in the Cross member 3 incorporated or at its outer ends be arranged in front of the head so that the outside of the pipe pieces 9 lying parts of the cross member 3 are omitted.
  • FIG. 8 to 12 show the design of the sleeve 6 and the assigned upper flange ends as a bayonet lock.
  • the same shape having outer projections 17 are in alignment the ends of the abutting top chords.
  • the sleeve 6 can not be from the support member be removed. Unless removing the sleeve 6 is intended, it receives both ends and in alignment the same internal protrusions 16. You can then alternatively on the top chord of the adjacent support element 1 postponed and there during transport to be deposited.
  • Each carrier element 1 is preferably one with a Sleeve 6 provided strut 7 assigned so that not two different types of support elements are formed and must be sorted out during assembly.
  • the most Bridge end missing on one side of the bridge Strut and thus missing triangular connection can then by a specially designed strut 7 ' 13, or at Use of one of the struts 7 with the sleeve 6 can an intermediate piece 19 in the end of the upper chord 4 are used (Fig. 14).
  • the intermediate piece 19 is tubular in such a way that it is in the Upper chord can be pushed in and points to the outer end two projections 17 'on the Align outer projections 17 of the upper chord 4.
  • the sleeve 6 in the locked and unlocked described manner. 13 is the one used Sleeve 6 'made so that a sleeve 6 in the transverse direction is cut in the middle and to the Interface an end plate is attached. In the middle the strut 7 'is also welded to the interface. Since the section of the sleeve 6 used Has internal projections 16, it can on the end of the Upper chords 4 pushed on and in the manner described locked by turning.
  • the cross member 3 ' accordingly at each end two at a distance from each other arranged incorporated pipe pieces 9, which the same coupling parts as the execution according to 1 to 7.
  • the bottom chord parts are also 5 'and 5' 'of two carrier elements 1' and 1 '' on their Provide ends with the hammer head-like elements 8.
  • the carrier elements have 1 'and 1' 'arranged on their truss struts Sleeves 26 and 27, which - lined up - the Form top flange 4 '. You reach for it hinge-like into each other.
  • the carrier element 1 ′′ has three sleeves 27 between which are two sleeves 26 of the carrier element 1 ', the ends of the two outer sleeves 27 in the transverse direction of the bridge with the ends of the lower flange parts 5 'and 5 '', which together form the lower flange of the double-walled Form the bridge girder, align. Between the sleeves 27 Adjacent carrier elements 1 ′′ thus remain Clearance of the width of the cross member 3 ', the is bridged by an intermediate sleeve 29.
  • the sleeve 29 has three struts 30, 30 ', the each with its other end in the same way as that Struts 7 are coupled to the cross member and are arranged so that two struts 30 in parallel run and the third, intermediate strut 30 'against the other two around the top chord axis is pivotable. After coupling occurs on this Form a triangle in two directions, which the Fix the sleeve 29 so that it fits with the sleeves 27 in the Position of use is aligned. If necessary, it can Tube connected to the sleeves 26 and 27 in a shear-resistant manner be, e.g. B. by - not shown - locking elements.
  • the sleeve 29 can be omitted if the outer Sleeves 27 are extended so that they each on adjoining support element 1 ''.
  • the assembly of a bridge section is thus made two or four support elements, a cross member and the associated roadway plates formed during a Bridge field that is decisive for the calculation itself between the centers of two cross members 3 and 3 ' extends.
  • the shortest bridge of the type according to the invention accordingly has two carrier elements 1 and four Support elements 1 'and 1' 'and two cross members 3 and 3' on.
