Definitions

  • the present invention relates to a building structure according to the preamble of claim 1, a method according to that of claim 10 and a use of the mentioned method according to claim 18.
  • a tunnel structure commonly used today is shown on the basis of a cross section through a tunnel tube.
  • a first layer 5 is applied to the natural ground surface 1 of the tunnel tube that has broken out. It is either created using formwork with segments and subsequent mortar backfilling or as a shotcrete layer.
  • this layer 5 there is a sealing layer 7 made of plastic, in the form of welded, prefabricated film sections made of polyethylene or soft PVC. So that future leaks can be localized in a limited surface area and a corresponding re-sealing can be carried out, the sealing layer 7 designed as a film is divided into partitioned zones.
  • the actually load-bearing layer 9 It is formed by shells and backfilling and is, according to the respective static requirements, with a steel reinforcement armored.
  • Technical installations 13 are mounted on the inner surface 11 of the tunnel formed in this way and mostly one coat of paint is applied.
  • the known overhanging building structure shown in FIG. 1 using the tunnel structure has the following disadvantages:
  • the application of the sealing film forming the layer 7 is complex.
  • the film itself is susceptible to injury, such as when laying steel reinforcements for layer 9.
  • layer 9 is costly and, moreover, permits local expansion and contraction of the tube and the formwork of tubes with small curve radii only with great effort.
  • the building structure of the type mentioned above is distinguished by the characterizing part of claim 1, preferred embodiment variants according to claims 2 to 9. Accordingly, the method of the type mentioned above is characterized by the characterizing part of claim 10, with preferred embodiment variants according to claims 11 to 16.
  • the building structure according to the invention is preferably and according to claim 17 a tunnel structure, and following the wording of claim 18, the above-mentioned method is preferably used for lining tunnel tubes.
  • the first layer can be formed directly on the natural ground by a sealing layer which acts analogously to layer 7 of FIG. 1, or it is, additionally and analogously to the layer sequence 1, a sealing layer is additionally provided.
  • the first layer - analogously to 5 of FIG. 1 - is preferably essentially formed from shotcrete and the sealing layer - analogously to 7 of FIG. 1 - is provided between the first and the second layer.
  • a sealing layer on the first layer - analogous to 5 of FIG. 1 - is also clawed in that profiles are formed on the surface of this last-mentioned layer, preferably with a density that corresponds to the respective one Corresponds to stress requirements.
  • a granulate is embedded in the sealing layer, whatever is provided, preferably in the form of chippings, with which an optimal anchoring profile is realized for a layer adjoining the outside, as in particular for the second layer - analogously to 9 of FIG. 1.
  • the sealing layer is further formed in a preferred embodiment as a sprayed film, for example from a polyurethane reaction resin. It is either sprayed directly onto the natural ground, the inherent surface profile of which acts directly as a claw profile, or onto a first layer formed in analogy to layer 5 of FIG. 1.
  • the outer second layer is also preferably made predominantly of shotcrete, with which, in a preferred combination, all cladding layers are applied by spraying.
  • the clawing according to the invention is of further importance here, namely that it considerably simplifies application of the layers in spraying technology, and even enables them on an industrial scale. Due to the clawing of the layer composite used in accordance with the invention, none of the applied layers is lost, with the result that the cladding thickness D can be significantly reduced or the breakout radius can be reduced accordingly.
  • the sealing layer can be sprayed, which is much less complex than the known film application.
  • the entire layer composite can absorb shear stresses due to the positive locking.
  • Fig. 2a shows a section of a building, in particular
  • Tunnel cladding structure formed according to a first embodiment of the invention
  • FIG. 3 shows a representation analogous to FIG. 2a, a further embodiment of the building structure according to the invention.
  • FIGS. 4a in a representation analogous to FIGS. 2a and 3, a third embodiment variant of a building structure according to the invention
  • FIG. 4b shows an enlarged section of the structure according to FIG. 4a with a further variant for the targeted generation of a claw profile
  • a first layer 5a which preferably consists of shotcrete, is deposited on the natural surface 1, in analogy to FIG. 1.
  • a profiling is worked into the surface of the layer 5a by mechanical intervention or by special spraying technology, for example by spraying with saccaded feed.
  • the profiling is formed by knobs, webs, grooves, etc.
  • the sealing layer 7a is sprayed onto the finished layer 5a, for example by using a polyurethane reactive resin.
  • the film-like layer 7a depicts the profiling of the surface 15 practically 1: 1 to the outside.
  • the layer 9a is applied, which clings to the layer 5a via the layer 7a thanks to its surface profile.
  • a layer composite is thus created which can also absorb shear stresses in the zone of the sealing layer 7a due to the clawing to the same extent as the layers 5a and 9a.
  • anchors 17 can, if desired, be used to anchor layer 9a and / or layer 5a to the natural ground.
  • FIG. 3 shows a further building structure according to the invention.
  • a relatively thick sealing layer 7b is applied to the natural surface 1, which clings to the inherent profile of the natural surface 1.
  • a polymer concrete is used for example.
  • the initially exposed surface of the sealing layer 7b is profiled by mechanical intervention, preferably with a predetermined density, be it by knobs and / or grooves and / or grooves and / or notches, etc.
  • the layer 9a is applied directly to the sealing layer 7b, preferably again by means of concrete spraying, and claws onto the profile at 17 with the sealing layer 7b.
  • anchors 17a are provided which anchor the layer 9a to the natural subsoil and thus also allow its load-bearing capacity to be used to an increased extent.
  • one of the at least two layers to be provided is used directly as a sealing layer. On the one hand it is anchored to the profiling inherent in the natural ground, on the other hand it becomes an on its surface Profiling 17 is provided, on which the adjoining layer 9a is clawed.
  • the sealing layer 7b which is relatively thick there, forms a film-like, thin sealing layer 7c, which is sprayed directly onto the micro- and macro-profiled natural base layer.
  • Surface 1 is sprayed on.
  • the layer 9a is applied directly to the sealing layer 7c, again preferably by concrete spraying, and claws over the layer 7c with the profiles inherent in the natural surface. If necessary, the layer 9a can in turn be anchored to the natural ground by means of anchors 17b.
  • FIG. 4a in FIG. 4b and FIG. 2a in FIG. 2b further preferred embodiments of the sealing layer 7c or 7a sprayed on in the form of a film are shown.
  • a granulate 19c or 19a is embedded in the layer material, preferably chippings.
  • FIG. 3 to implement the profiling 17 shown there, as shown at 19b, in that, before the spray application for the layer 7b, a layer of granules, preferably a grit, into the still soft layer Plastic mass of layer 7b is shot.
  • Fig. 1 results in a smallest radius of curvature
  • the present invention enables very significant savings in the production of the building structures mentioned.
  • it can also be used for bridge covers, generally composite constructions, in particular on a concrete basis, to increase the load cross-section of a construction with at least the same geometric cross-section.
