Definitions

  • the present invention relates to a method for producing a segment prefabricated bridge from prefabricated, in support and / or longitudinal direction with each other at contact surfaces juxtaposed concrete segments and a corresponding segment prefabricated bridge.
  • Segment prefabricated bridges are usually produced in the so-called match-cast process.
  • the segments are produced individually in the precast plant or on the construction site.
  • the new segment is concreted against the contact surface of the previous segment.
  • the previous segment serves as part of the formwork for the inner contact surface of the newly concreted segment.
  • profiles which are provided in the outer contact surface by a corresponding formwork, taken over by the new segment accurately.
  • the two segments thus fit very closely together. Due to the profiling, which can be performed wavy or toothed, the friction of the two segments is significantly increased together. If the two segments are pressed together, then thrust forces and torsional moments can be transferred very well. If the joints are additionally glued, the result is a bearing behavior which is comparable to a monolithic prestressed concrete bridge.
  • a concrete layer is additionally applied to the prefilled segment bridge.
  • the concrete layer forms a continuous concrete strip, which forms a roadway for rubber-tired vehicles by an appropriate design or equipment of the surface with, for example, asphalt.
  • a segmented-type bridge which is composed of several individual segments.
  • the contact surfaces of the individual segments are flat and unprofiled and are partially machined.
  • the individual segments are then pressed together by means extending in tubular sheaths H tension rods T gap without any gap.
  • the existing between the tubular casing H and the tie rod T channel K is filled with cement mortar.
  • a connection of the two segments through the cement mortar does not arise, since this is arranged exclusively in the tubular shell H for the tension rod T.
  • the document is also not apparent whether the cement mortar also extends beyond the contact surfaces.
  • Object of the present invention is to provide a segment prefabricated bridge, which has a high structural strength, despite series production is tuned to individual bridge gradients and is fast and economical to produce.
  • the profiles of the juxtaposed contact surfaces of the segments are at least partially mechanically processed, in particular ground.
  • milling or a combination of different mechanical processing steps can, for example, be considered.
  • the contact surface can be discussed. The segments thus fit very closely together and are pressed close to each other.
  • the individual segments are placed against each other at the machined, in particular ground contact points. This results in a precisely predetermined arrangement of the individual segments together whereby a predetermined course of the bridge can be achieved.
  • the two segments can be butted against each other, resulting in the relative position of the adjacent segments to each other. But they can also be interconnected by means of a gearing.
  • the gearing is produced precisely by means of milling and / or grinding.
  • the achievable tolerances of the bridge profile and the individual segments to each other are excellent compared to achievable with conventional methods values.
  • the segments are placed together in exact position, whereby subsequently the resulting cavities are cast in addition to the contact surfaces. This creates areas in which transversal forces are removed can be.
  • the filled in the cavities potting material acts as a bar, which is located exactly between the two segments and thus optimally can absorb shear forces and torsional moments.
  • the segments are first clamped against one another and then the cavities are poured out between the contact surfaces.
  • the ground contact surfaces for the positioning of the segments are obtained and the cavities are optimally utilized for the transmission of power by means of the casting compounds cast into them. Open joints are completely avoided.
  • the upper side of the roadway slab is provided with a brushstroke structure and is directly passable.
  • a very dense top of the deck plate is achieved.
  • the formwork floor or the formwork wall is provided with a rubber mold with a brushstroke structure
  • the upper side of the carriageway panel receives precisely this brushstroke structure with a roadway optimally designed for driving with rubber-tired vehicles.
  • a roadway is created, which is fast and economical to produce.
  • An additional road surface is not required.
  • by the solid juxtaposition of the individual segments creates a virtually seamless roadway, which is particularly good and comfortable to drive.
  • damage due to penetrating into pores or joints freezing water is almost impossible, since the top of the carriageway plate by the type of production has virtually no pores and the joints between the individual segments due to their milled contact surfaces match each other.
  • a segment prefabricated bridge according to the invention consists of prefabricated segments of concrete, which are placed against one another in the supporting and / or longitudinal direction.
  • the contact surface is at least partially machined, in particular ground. This allows a virtually gapless transition between two segments when they are placed against one another.
  • the segments are designed with a single or multi-cell box cross-section with floor and deck plates, which are connected to webs. This creates a stable and resilient construction of the bridge.
  • the segments are plate-shaped and arranged shear-resistant on a carrier.
  • the segments can be placed on a steel or concrete beam, which have shear bolts, which engage in recesses of the segments. The recesses can then be potted in the subsequent composite.
  • a transverse bias of the segments is provided.
  • the contact points are machined so that the segments are close to each other, whereby the segments form a virtually seamless contact.
  • the durability of the bridge is thereby positively influenced.
  • the power transmission is significantly improved.
  • the segments are sheared together by means of a toothing.
  • the toothing is produced by means of milling and / or grinding exactly to obtain the desired course of the bridge, without offset of the individual segments.
  • the segments are placed together in exact position, which results in a corresponding design of the contact surfaces sealed cavities, which are filled with potting material. As grout is grout in question, which penetrates into the cavities and solidifies there.
  • filling openings for the potting material are provided in the cavity, which is formed by the juxtaposition of the segments.
  • the potting material is advantageously poured into a filling opening until it flows out of a further opening of the cavity, which is advantageously arranged at the other end of the cavity. This ensures that, largely without air pockets, the cavity is completely filled with potting compound.
  • the potting material concrete or grout This low-viscosity concrete flows very well into the cavity and fills it completely.
  • the contact point may also be provided with adhesive in order to achieve an additional connection of the two segments and a seal here as well.
  • the segments have external and / or internal tendon guides and deflection saddles for tendon guidance, a targeted introduction of force is ensured.
  • a centering device such as a centering cone, which cooperates with an incorporated pocket of the adjacent segment, the segments are mounted accurately to each other and it is an additional removal of a thrust allows.
  • end segments of the bridge If recesses for receiving tendon heads are arranged on end segments of the bridge, then the end segments can be integrated into the transition structure of the bridge. The end segments can also accommodate the bridge bearings.
  • this is made of self-compacting concrete. Due to the dense structure of the concrete used, in particular in connection with the introduced surface texture, the requirements for high grip, noise emissions, mechanical abrasion by tires and durability with respect to frost and de-icing salt attack and chemical attack, for example, by acid rain, excellent fulfilled.
  • FIG. 1 is a section through a side view of a segment prefabricated bridge 1 with in the supporting direction against contact surfaces 14 juxtaposed plurality of segments 3,4 and 5 shown.
  • the segments extend transversely to the bridge 1 and are lined up in the longitudinal or supporting direction.
  • the segment prefabricated bridge 1 has two fields, which rest on three bearings 2. In the area of the bearing 2, two end segments 3 and a middle segment 4 are arranged.
  • the segments 3, 4 and 5 are clamped so tightly together with tendons 6 that they are suppressed at the joints 7 between the individual segments 3, 4 and 5, so that they are pressed firmly together even at maximum load.
  • the tendons 6 are mounted in the end segments 3 in recesses 18 with tendon heads.
  • Each segment 3, 4 and 5 consists in this embodiment of a bottom 8 and a carriageway plate 9, which are interconnected by means of a plurality of webs 13 and form a box cross-section.
  • tendons 10 are arranged, which are stretched after concreting the respective segment 3, 4 and 5 and provide additional strength of the segments 3, 4 and 5.
  • 9 cavities 11 are arranged both in the bottom 8 and in the carriageway plate.
  • the cavities 11 are filled after compression of the individual segments 3, 4 and 5 with potting material and thus provide thrust toothing of the individual segments 3, 4 and 5.
  • Above and below the cavity 11 are in the bottom 8, the deck plate 9 and the Webs 13 as part of contact surfaces 14 contact points 12 are arranged.
  • the contact points 12 are ground and / or milled after the production of each individual segment 3, 4 and 5 according to the requirements of their slot within the bridge 1. So it is possible by this mechanical processing, same mass-produced segments 3, 4 and 5, in particular but the segments 5, individually modify, so that, for example, a slope or radii or crests can be mapped in the segment prefabricated bridge 1.
  • FIG. 2 is a front view of a segment 5 of a segment prefabricated bridge 1 is shown. It is in this case a three-cell box cross-section shown with a bottom 8, a deck plate 9 and four bars 13. Within the boxes extend the tendons 6, which press the individual segments 3, 4 and 5 to each other. At the contact surface 14 is in the region of the bottom 8 and the carriageway plate 9 each show a part of a composite with an adjacent segment 3, 4 or 5 resulting cavity 11 which extends substantially over the entire length of the bottom 8 and the carriageway plate 9. In other, not shown embodiments of the invention, however, only a partial course of the cavities 11 or only the arrangement of a cavity in the bottom 8 or the carriageway plate 9 or the webs 13 is possible.
  • the cavity 11 has two openings 15. These openings 15 are used for filling a potting compound.
  • the potting compound is filled in one of the two openings until it runs out of the other opening 15. This ensures that air pockets are largely avoided. This results in a very effective shear toothing of two juxtaposed segments 3, 4 or 5.
  • the area of the contact surface 14, which does not have the cavity 11 or the opening 15, serves as a contact point 12.
  • the contact point 12 is mechanically, preferably processed by grinding and thus ensures a very precise position and shape.
  • the segment 5 can correspond optimally to the adjacent segment 3, 4 or 5 and has the effect that there is a largely dense contact between the two segments 3, 4 and 5 set against one another.
  • the tendons 6 are guided in external tendon guides 19. Deflections of the tendons 6 can be done by means not shown Umlenksattel.
  • an elastomeric strip 21 is arranged at the peripheral edges of the segment 5.
  • damage to the segment during transport and installation are avoided.
  • a seal of the joint with the elastomeric tape is obtained.
  • the same effect is achieved by a sealing tube instead of the elastomeric band 20.
  • Centering devices 22 are shown schematically on the webs 13. They facilitate assembly by, for example, conical pins engage in correspondingly formed recesses. When merging adjacent segments they are positioned exactly to each other.
  • the surface of the deck plate 9 may be concreted in the form of a brush stroke or other structure.
  • the segment prefabricated bridge 1 can thus serve with its surface already as a roadway for rubber-tired vehicles.
  • the use of a high-strength concrete meets the requirements for a directly drivable surface of the carriageway plate 9.
  • a special superstructure of segment prefabricated bridge 1 is no longer necessary, especially since the individual segments 3, 4 and 5 already have high strength by the shear gearing of the poured cavities 11 and an additional concrete is no longer required.
  • the baffles can be set up as needed and road changes to adapt to the traffic can be easily realized. If the load collective is increased, the load capacity of the bridge can be increased by additional tendons.
  • FIG. 3 shows a section through a side view of another segment prefabricated bridge 1 ', which is similar to the segment prefabricated bridge 1 of Figure 1 and 2 stored and designed. The difference is that individual segments 50, 51 divide the bridge 1 'not transversely to the supporting direction but along the supporting direction. There are thus individual longitudinal members present, which are divided along the supporting direction and connected to each other.

  • a part of a designed in the manner of a tongue and groove connection teeth 110 here a spring shown.
  • the toothing 110 runs along the contact surface 140 in the region of the upper flange 90, which forms the carriageway plate, at the point at which the middle segment 50 makes contact with an adjacent segment 50, 51.
  • the toothing 110 is brought to an exact shape by milling and / or grinding, so that the contact with the adjacent segment 50, 51 is a positive fit.
  • the teeth 110 causes that in a transverse force, for example by a heavy load traffic, which is guided over the bridge, an offset of the individual segments is avoided.
  • a cavity 11 In the bottom, which forms the lower flange 80 of the carrier, a cavity 11, similar in construction FIGS. 1 and 2 arranged. Laterally of the cavity 11, a contact surface 140 is provided with a contact point 12, which is also processed very accurately.
  • the individual segments 50, 51 are pressed together, for example, with a tensioning member 60. Then, a potting compound is filled into the cavity 11 via the opening 15 and thus the segments 50, 51 secured against transverse displacement.
  • a potting compound is filled into the cavity 11 via the opening 15 and thus the segments 50, 51 secured against transverse displacement.
  • FIG. 4 is a cross section through a segment prefabricated bridge 1 'shown.
  • the toothing 110 as well as the cavity 11 and the contact point 12 with respect to their mode of action is clearly visible.
  • the payment 110 and the contact point 12 is made very precisely by milling and / or grinding and thereby forms an exact stop surface for the adjacent segment.
