Definitions

  • the invention relates to a bridge structure according to the preamble of claim 1.
  • the US 6,081,955 A shows a sandwich-like structure of the support structure of a bridge.
  • the EP 02 83 383 A1 describes a bridge with a bridge deck, which is reinforced by a cross-sectionally triangular beam.
  • the WO 94/04756 shows a bridge construction with arcuate beams.
  • the AT 332 446 B again describes a portal-like bridge construction with arched in the longitudinal direction of the bridge supports.
  • a bridge structure known which rests on pillars wherein the support structure of this bridge structure is formed in box-shaped cross-section.
  • the box-shaped structure is in this case held approximately trapezoidal, wherein the legs of this trapezoidal support structure are formed tapering in the direction of the pillar.
  • the top of the box-shaped support structure forms the deck that receives, for example, the road or rails.
  • a constructive solution for a support structure of a bridge structure is known from this reference, said support structure has two struts in cross-section, each tapering at a relatively flat angle to the central load receiving deck and form a structural unit with the deck.
  • a vertically oriented rectangular profile is provided, which connects the struts on the one hand and the deck on the other hand, and also projects beyond the deck.
  • At the top of this profile has a horizontal leg on, wherein such a leg has its counterpart in the region of the foot region of the struts, so that there is a principle in cross-section double-T-shaped profile.
  • This centric profile which is formed in cross-section in the manner of a double-T-profile, serves in this support structure according to the prior art as the element which receives substantially the entire load and dissipates in the columns or pillars.
  • the converging towards the deck struts are the load distribution, the surface forces introduced into the deck. That is, the primary support structure for load-bearing is essentially formed by the cross-sectionally double-T-shaped vertical profile.
  • the core of such a bridge construction is thus a central support unit which absorbs substantially all acting forces.
  • the idea underlying the invention is now to provide a support structure for a bridge structure, which in contrast in the prior art is not characterized by a central support structure, as in the prior art according to of the U.S. Patent 5,231,931 described, but to provide a support structure in which the entire support structure carries, ie essentially the forces acting on such a bridge structure forces are uniformly absorbed by the support structure as a whole.
  • a support structure with approximately triangular cross-sectional shape wherein the angularly extending to the horizontal cathetus of the triangular cross-sectional shape are formed in the longitudinal direction of the bridge structure as a support shells, which are curved in the direction of the horizontally extending cathodes.
  • bridge structures are needed when it comes to spanning canyons, for example.
  • Such bridges for pipelines are characterized essentially by spaced-apart supports on which the pipeline is stored, wherein the actual pipeline pipes are held by a box-shaped tensile structure. That is, at least laterally surface structures are provided, which stabilize the pipeline on the supports. Preferably, however, such a surface structure is also found on the top of the pipeline, wherein the individual surface structures are connected to each other in the manner of a box.
  • This construction is very complicated, which is why there is a need in the pipeline construction to provide simpler and less expensive constructions, which are nevertheless able to bridge large spans in pipeline construction.
  • a bridge structure which is suitable for pipeline construction, according to experience, in particular characterized in that the catheters extending at an angle to the horizontal form the deck of the bridge structure.
  • the bridge construction is rotated by 180 °, and thus the otherwise downwardly directed bulges are now open at the top to accommodate the lines of two pipelines.
  • the cathodes are arched in the transverse direction of the bridge structure, wherein the pipes are received by the respective curvature quasi form-fitting manner. This means that the curvature is met in a circular arc.
  • the constructions found are therefore characterized by the fact that the respective construction as a whole uniformly serves the absorption of force. In this respect, it is possible to make such a construction as a bridge structure slimmer and to bridge larger spans.
  • the catheter in the region of the side edge of the bridge structure, ie the support shells, with the horizontally extending catheter, ie the deck, running into each other forms a substantially perpendicular thereto oriented support bar.
  • a support bar or wing-shaped extension significantly increases the moment of resistance of such a bridge structure against deflection.
  • the support bar with the respective support shell forms a so-called shell structure, ie the curvature of the support shell continues into the support bar, so that when loading the support structure of such a bridge structure for receiving the forces both the triangular support structure as well as the support strips described above are used.
  • the support bar extends in height over the deck. From this it is clear that in such a case, the support structure in cross section has the appearance of a horizontal double-T-profile, wherein the web of such a double-T-profile having the previously described triangular support structure. That is, the support bar can survive both up and down, in both variants. It has been found by calculation that such a bridge structure, especially in connection with a concrete according to the DE 103 32 491 , an increased load capacity allows at the same time large spans.
  • the bridge structure in the longitudinal direction of the bridge structure in the flank area, so for example in the region of the support bar or directly in the support bar of the bridge structure.
  • the clamping means may be, for example, wire ropes.
  • the bridge structure in the region of the support shells is arched in the longitudinal direction of the bridge structure, so that a curvature of the support shells results both in the longitudinal direction and in the transverse direction. Due to the curvature in the longitudinal direction, in particular, the load-bearing capacity of such a bridge structure is further increased.
  • the curvature in the longitudinal direction may be such that pillars are formed by the curvature, d. h., that the vault merges into the buttresses.
  • the angle to the horizontal extending catheters have a support leg in the region of their merge.
  • the support foot is formed in the confluence of the cathetus to the catheter, that is part of the actual bridge structure, or there is the possibility that the support leg has a notch-shaped receptacle for the bridge structure at the confluence of the catheter, so that the actual bridge structure and the support leg are separate components that can also be produced separately.
  • This form of production requires smaller forms and is therefore cheaper.
  • the support leg rests on a pillar, which is formed according to the desired height.
  • the support strips and / or the horizontally extending catheters are perforated.
  • the reason for such a perforation lies in particular in the weight saving, whereby such a weight saving always accompanies with larger spans of the bridge. This is because the span of the bridge is essentially limited by the weight of the bridge itself.
  • the bridge construction comprises a substantially triangular support structure 20, with the support strips 30 arranged laterally on the support structure as part of the support structure.
  • the triangular support structure comprises the deck 21 and the two support shells 22 and 23 connected to the deck form a triangle. It is essential here that the support shells 22 and 23 with their bulges continue into the lateral support strips 30 which protrude on both sides of the deck. It is also essential that the ratio between the width and height of the triangular support structure, as well as the height of the triangular support structure and the Height of the downward support bar are variable. It should be noted at this point that the orientation of the support bar relative to the deck can be made at almost right angles, as shown in the illustration Fig. 1 or according to Fig. 3 is removable. However, there is also the possibility to reduce the angle ⁇ between support bar and deck, wherein ultimately the position of the support bar is dependent on the side acting on the bridge structure forces, and in particular the acting wind forces.
  • the support shells 22, 23 are formed curved, in the direction of the deck 21 curved. It is important that in the area of the side flanks (arrow 25), both the deck 21 and the support shells 22 and 23 form a shell construction together with the respective support strip, d. h., The curvature of the respective support shell 22, 23 continues into the respective support bar 30.
  • Insofar corresponding clamping means 40 for example in the form of wire ropes are provided in the region of the support strips.
  • the support shells are formed not only curved transversely to the longitudinal axis, but may also be curved in the longitudinal direction, so that the curvature of the support shells 22 and 23 takes place both in the longitudinal direction and in the transverse direction.
  • the curvature can be designed in the longitudinal direction such that this curvature passes into corresponding support pillars 60.
  • Fig. 4 results in the formation of the bridge structure for receiving one or more lines of a pipeline. Visible is the bridge structure according to the Fig. 1 a and 1 b have only been rotated by 180 °, wherein the curvatures of the cathodes 22 and 23 are held in a circular arc in shape in order to receive the lines form-fitting at least in two spatial directions. It is essential here that the required according to the prior art box-shaped tensile structure for holding the lines can be omitted.
  • the support rails of the bridge structure are perforated, which also applies to the angle to the horizontal extending catheters.
  • the perforation openings are respectively designated 35 and 25.
  • the support shells As already mentioned, it is possible to form the support shells curved in the longitudinal direction, thereby forming a support for resting on the ground. However, it is also possible to provide support legs, which are arranged in the convergence of the two angles to the horizontal extending catheters. The support legs 50 are supported on separate posts 60.
  • the support feet can be part of the bridge construction in the sense of a single component; However, it is also possible to produce the support legs 50 as separate components. In this case, the support feet have a notch for receiving the angularly tapered support shells as the catheters 22, 23rd
  • the bridge construction runs on pillars which support the horizontally extending cathodes 21.
