Definitions

  • the invention relates to a method for creating a single or multi-span bridge, which has a steel structure and a monolithic concrete carriageway slab, wherein plate elements are prefabricated, laid on the steel supporting structure and joined together by a non-positive longitudinal connection to the concrete carriageway slab.
  • Such a bridge construction is known for example from FR-A 2 622 907 A.
  • groups of prefabricated plate elements are first placed on the structure in the area of a bridge pier, which are transported by means of a crane that can be moved on the structure.
  • tension wires are drawn through channels provided in the plate elements and each group of plate elements is prestressed.
  • further plate elements are inserted between the groups, a different means of transport having to be used since the structure in the area of the pillars is no longer accessible. After filling the gaps, additional tension wires are pulled through the entire length of the bridge and put under tension.
  • the plate elements each have a central and two end-side recesses, with the end-side recesses of plate elements arranged in a row complementing each other. Reinforcement elements stand high in the recesses and are arranged on the structure.
  • the individual recesses are then filled with in-situ concrete, whereby a partial bond is made between the structure and the concrete slab.
  • this partial network is only sufficient in cases of medium loads, so that not all bridge construction projects can be created with this design.
  • a disadvantage here is not only the local connection between the carriageway and the supporting structure, but also the problem that arises when the required composite reinforcement cannot be accommodated in the recesses.
  • the invention has now set itself the task of solving this problem, so that all bridge construction projects can be carried out in such an advantageous prefabricated construction, and a real alternative to the currently common construction methods, namely the production of the entire pavement slab is achieved in in-situ concrete.
  • the concrete slab is concreted on a formwork that is supported on the steel structure.
  • fastened composite materials usually stud bolts, which are concreted into the concrete carriageway slab, guarantee the bond that is given over the entire length immediately after the in situ created concrete carriageway slab has hardened.
  • the effort for formwork, reinforcement and concreting of the carriageway slab requires a not inconsiderable proportion of the total construction time and the cost of such a composite bridge.
  • the method according to the invention achieves the object specified above in that a full composite is produced over the length between the concrete carriageway slab and the steel structure.
  • a first embodiment of the method provides, in particular before the transverse joints are closed, that plate elements are produced which have concrete plate parts which are spaced apart from one another in the areas of the support on the steel structure and which are connected by the plate reinforcement and form continuous compound streets, and that 'The concrete slab parts are placed on the steel structure in such a way that the upper chords of the steel structure, on which high-quality composite materials are provided, form a floor formwork of the compound streets, and that the full composite is produced by concreting the compound streets.
  • the tension, compression and also shear reinforcement elements of the prefabricated plate elements, which extend across the steel structure are completely exposed between the concrete plate parts.
  • the continuous compound alley makes it possible to provide these reinforcements as well as the upstanding composite means in sufficient number and all necessary arrangements, since in this way continuous in-situ concrete ribs are created in the longitudinal direction of the bridge. 3
  • one-piece plate elements are made, in which in the areas of the support on the steel structure with high
  • Steel lamellas provided with bonding agents are integrated, the undersides of which are exposed and correspond to the contact surfaces on the steel structure, and that after the plate elements have been placed on the steel structure, the full composite is produced by a non-positive connection between the steel structure and the steel lamellae of the prefabricated plate elements.
  • the steel lamellas are already integrated in the concrete of the plate elements in a suitable manner in prefabrication and can be equipped, for example, with headed studs projecting into the concrete.
  • the steel supporting structure has in particular a plurality of longitudinal beams with upper chords which can contain an assembly aid by being provided with areas which rise obliquely outwards.
  • the top chords can be V-shaped or channel-shaped, for example, with a horizontal central section.
  • the steel lamellae of the plate elements and the upper chords of the steel structure are screwed together.
  • the steel lamellae have screw bolts that protrude downwards, penetrate the holes in the upper flange and are secured by nuts.
  • slots which are open towards the edge can also be provided instead of the holes.
  • the time for the composite production can be selected depending on the circumstances before or after closing the transverse joints.
  • Plate elements can also be provided, in which elements protruding from the upper chords engage.
  • top chords of the steel structure are welded together after installation or glued to one another during installation. In both cases, assembly and / or position securing, for example by means of fitting or guide elements, is advantageous.
  • a first embodiment provides that this non-positive connection is established by a preferably reinforced grouting concrete of the element joints.
  • Another possibility for the non-positive longitudinal connection of the plate elements provides that steel longitudinal beams are arranged on the plate elements, in particular on the underside between the suspension areas, and after the laying the abutting longitudinal beams are welded or screwed together.
  • a simple potting compound is sufficient to close the transverse joints between the panel elements.
  • a particular advantage is that all prefabricated plate elements can be delivered and moved with conventional transport vehicles, so that no special, 5 mobile crane must be installed on the structure; and no gaps between pillar areas are subsequently filled with plate elements.
