Definitions

  • the invention relates to a roadway storage at the junction of two bridge sections of a portable bridge.
  • Bridge bearings made of elastomers or elastomeric inserts have long been known in general bridge construction, see e.g. AT 320 001. They are there to compensate for bridge length changes, which arise in particular due to thermal expansion of the bridge materials or due to deflection of the bridge under load.
  • the invention is therefore based on the object to provide a roadway storage at the junction of two bridge sections, which meets the above requirements in an excellent manner.
  • a roadway storage is achieved at the transition between two bridge sections, with the formworks and without additional fasteners the roadway planks are secured in all three levels, the structural components of the storage take the loads introduced and distribute.
  • the storage according to the invention is self-locking, i. All involved components of the bridge are simply screwed into each other, put in or hung without screw or solid bolt connections. Thus, the structural conditions for a quick and uncomplicated assembly and disassembly of the bridge are created.
  • the clear design language of the components enables a self-explanatory design without any special aids.
  • the roadway planks are inserted directly into the recesses on the cross member of the bridge. End fittings are therefore not required for the roadway planks.
  • the use of small, easily lost parts is avoided. Defective or lost components can be replaced without major adaptation effort.
  • elastomers as bearing material ensures that the contact and contact surfaces for the rigid roadway planks (preferably made of CFRP) are adjusted in size and geometry depending on the height of the loads in all directions (except for the top). In particular, a line pressure on the roadway planks is avoided.
  • the use of elastomers also achieves noise insulation.
  • the interposition of the elastomeric material prevents contact corrosion between CFRP fiber composite (roadway planks) and aluminum (cross member).
  • the bridge cross member made of metal (in particular Al) or CFK comprises one or more additional elastomer molded parts, in which the recesses for receiving the roadway planks are incorporated.
  • An elastomer molding is connected by gluing or vulcanization with the metal or CFRP of the cross member.
  • An elastomer molding of the storage according to the invention is connected over a large area with a bridge cross member. Stress peaks in the upper flange of the pressure-loaded cross member, as they are e.g. result in screw or bolt connections in the form of notch stresses are avoided because the cross member has no holes.
  • the recesses for receiving the roadway planks can also be incorporated directly into the metal (eg by milling).
  • the surface of a recess is in this Case coated with an elastomeric material.
  • the layer thickness can be a few millimeters to a few centimeters.
  • the connection between metal and elastomer can be made by gluing or vulcanization.
  • the bearing according to the invention with its essential components can also be used for the transition between bridge section and ramp section of the bridge, the number of different bridge components is reduced. As a result, a more economical production of the bridge is possible.
  • Figs. 1 and 3 show an embodiment of the roadway support according to the invention between two bridge sections.
  • the bridge cross member 2 which has a base profile 21, for example made of CFRP or aluminum, which is connected flat with an elastomeric molded part 1.
  • the planar connection between elastomer molding 1 and base profile 21 of the bridge crossmember 2 can be done, for example, by means of an adhesive layer 9 (this type of connection is preferred if the base profile 21 is made of CFRP) or by vulcanization (for crossmembers made of Al).
  • recesses 12 are present, in which the abutting from both sides of the roadway planks 3 (preferably made of CFRP) can be inserted positively.
  • the elastomer molding 1 thus encloses each roadway screed 3 from four sides.
  • the roadway planks 3 are thereby secured in the road surface and down in position.
  • Up the pavements are 3 by a Fahrbahnniederhalter 4, preferably made of Al, secured to prevent jumping up of the planks in the crossing.
  • It is a profiled component whose two wings 41,42 each rest on the upper side of a roadway screed 3 and whose central part dips into the joint between the joints of two opposing roadway planks 3.
  • the roadway hold-down 4 has a locking rail 43 with a C-shaped profile, referred to below as a C-rail. In this C-rail engage a stud bolt 6 a.
  • the C-rail knows a hole 10 whose diameter is slightly larger than the diameter of the stud bolt 6.
  • the locking of the entire roadway storage takes place in that the roadway hold-down 4 is placed, the stud bolt 6 is inserted through the hole 10.
  • a displacement of the roadway lower holder 4 transversely to the bridge direction (ie in the direction of the cross member longitudinal direction), so that the C-rail surrounds the head 61 of the stud bolt 6.
  • the roadway hold-down 4 is secured at one end by a stop (not shown), at its other end by positive engagement with the Schrammbordhalter the bridge against unintentional displacement.
  • Other connecting means are not needed to lock the roadway storage.
  • the roadway hold-down device 4 extends in the transverse direction of the bridge over a plurality of roadway piles 3 and, in a first embodiment, can extend over the entire roadway width. In a further embodiment, two separate, equal roadway retainers are provided over the entire roadway width for one roadway half. Of course, other divisions are possible.
  • FIGS. 2 and 4 show an embodiment of the roadway support according to the invention between a bridge section and a ramp section of the mobile bridge.
  • a roadway screed 3 On one side of the storage abuts a roadway screed 3, on the other side a ramp support 8 with Rampentikbohle 81 and fitting 82.
  • the structure of the storage is largely identical to the construction shown in FIGS. 1 and 3 (like reference numerals designate identical components) ,
  • connecting plates 5 for example made of Al, available.
  • a connecting lug 5 dips into the recesses 12 in the elastomeric molded part 1.
  • the connecting lug 5 has holes, by means of which the connecting lug can be suspended in the stud bolts 6, to guide driving and braking loads in the bridge structure.
  • the connecting plate 5 is secured by the roadway hold-down 4. Similar to the roadway hold-down, a connecting plate 5 can extend over the entire width of the bridge. Alternatively, there may be a plurality of identical tabs extending together across the bridge width. For example, three identical connection lugs, each with a length of one third of the bridge width. In addition, of course, other divisions are possible.
  • the ramp supports 8 have a knob-shaped cross-section in the cross-section 83, which corresponds to a recess in a connecting plate 5.
  • the ramp carrier 8 can be suspended in a connecting plate 5 to connect the ramp carrier 8 to the bridge. Bulge 83 and corresponding recess are formed such that a pivoting of the hinged ramp support 8 within a certain angular range is possible.
  • the studs at the transition between the bridge and ramp section in addition to the locking of the roadway restraint perform the additional function to initiate driving and braking loads in the bridge structure exercise, it may be advantageous, the number of studs per unit length compared to the situation at the transition between two Bridge sections increase (see Fig. 3 with 4). So that the roadway hold-down 4 can be used for both embodiments shown in FIGS. 3 and 4, a total of three holes 10, 20, 22 are present in the C-rail.
  • Fig. 5 shows a further embodiment of the storage according to the invention at the transition between two bridge sections.
  • the cross member 2 consists in this embodiment of a metallic base profile 25, for example made of aluminum, on the upper flange centrally a metallic hat profile 75 is present.
  • the hat profile is not continuous but only partially in the range of a stud bolt 6 (eg Al) available (comparable to the hat profile 7 according to FIGS. 3 and 4, which is also available only in the area of the stud bolt 6).
  • the metallic stud bolt 6 is welded to the hat profile 75.
  • On the upper flange of the base section 25 is an elastomeric molding 11 applied, for example by vulcanization. In the material of the elastomer molding 11, the recesses 125 for receiving the roadway planks are present.
  • Fig. 6 shows a further embodiment of the inventive storage at the transition between two bridge sections.
  • the cross member 2 has a metallic base profile 28, e.g. made of Al, whose upper belt is thicker than the thickness of the other three profile walls.
  • the recesses 127 are incorporated directly into the material of the upper chord of the metallic base profile 28, e.g. milled.
  • the surface of the recesses 127 are coated with layers of elastomeric material 129, e.g. by vulcanization.
  • the layer thickness on the horizontal surfaces on which the roadway planks rest chosen thicker than on the vertical surfaces.
  • the stud bolt 6 is welded to the upper flange of the cross member 2.
