Definitions

  • the present invention relates to a connecting element with a metallic core for transmitting forces between a first part made of hydraulically setting material and a further assigned part of a building, the connecting element emerging from the building parts in a joint area and providing protection against corrosive influences from the outside has an envelope made of an elastomer, vulcanized onto the core and dimensioned so that it runs a little way into the hydraulically setting material, whereby the clamping point of the metallic core in the hydraulically setting material is moved around this piece into the interior of the structural part, wherein the elastomer sheathing in the area of the exit point of the connecting element from the structural part has a layer thickness in the millimeter range, so that displacements of the connecting element bending under load at the exit point from the elastomer sheathing be taken.
  • Such connecting elements are e.g. known from DE-A-34 46 006.
  • Cantilever panel connections e.g. the anchoring for balconies, loggias, parapets, attics and consoles or the anchoring of floor or ceiling parts are usually made with the help of continuous or interconnected metallic connecting elements.
  • these connecting elements can consist, for example, of the usual reinforcement elements, which are led out of the part to be anchored into the part of the building serving as anchoring base or vice versa.
  • these connecting elements can, however, also be specially designed to absorb compressive or bending moments. Such elements are then only provided at the transition point between the parts of the building to be connected and have the actual reinforcement nothing more to do; this is also the case when connection elements such as hooks or bolts have to be anchored.
  • the connecting elements were e.g. completely with an extremely thin protective coating of e.g. 60-80 microns thick coated as described in European Patent Application No. 0 189 890. Solutions are also known in which the reinforcement elements in the area of the entry point are provided with a protective metal coating (cf. DE-OS 37 02 677) or with a rubber pipe sleeve, as described in the aforementioned DE-A-34 46 006 .
  • the covering consists of an elastomer material, preferably an elastomer material used for bridge supports, such as chloroprene rubber (CR), ethylene-propylene rubber (EPDM) or butyl rubber (IIR).
  • CR chloroprene rubber
  • EPDM ethylene-propylene rubber
  • IIR butyl rubber
  • Such elastic, but at the same time hard and tough materials are also suitable for long-term use.
  • the transition from a protective coating with the smallest thickness to a coating with a thickness in the millimeter range from the material mentioned above offers the following advantages: the covering described is very tough and insensitive to the rough treatment on the construction site. In the joint itself, it acts as an absolute corrosion protection insofar as the corrosive influences are prevented from acting on the surface of the metallic connecting element.
  • the encapsulated covering also acts as a seal. Furthermore, the elastic covering reduces the risk of damage to the concrete in the event of a relative displacement due to temperature differences. This danger exists especially in balconies, which should be insulated as well as possible from the rest of the building.
  • the aforementioned relative displacement creates shear forces through which the connecting elements in the area of the entry point want to be inclined; The concrete is then expanded in a funnel-shaped or oval manner at the entry point of the connecting element over a longer period of time. This creates a crack in which corrosive media can penetrate.
  • the compressible and stretchable covering the risk of the entry point widening, as described above, is essentially eliminated and any expansion inside is placed behind the sealing area. This considerably increases the security against corrosion.
  • an elastomer is basically made with metal and / or e.g. Concrete is compatible; So there is no need to fear that additional, difficult to estimate electrochemical processes will take place.
  • Preferred embodiments have the features of dependent claims; in particular is the Provide formings on the outer surface of the casing for improved sealing effect against corrosive fluids.
  • Further preferred embodiments have features which ensure the adhesion of the covering to the connecting element even under the highest loads.
  • the use of an adhesion promoter with possibly prior galvanizing of the connecting element or the direct vulcanization of the covering onto the connecting element can result in the connecting element and covering being inseparably connected to one another and thus corrosion in the area of the Wrapping is completely excluded.
  • the connecting element can have any shape. Not only does the profile in cross-section play a role, changes in the length of the profile can also be provided.
  • 1 and 2 denote different parts of a building, in the present case both are made of concrete.
  • Part 1 can be used as a cantilever plate, e.g. Balcony, and part 2 as the corresponding anchoring part in the building.
  • the arrangement shown is symmetrical for simplicity; this is not mandatory.
  • the anchoring part 2 could also consist of e.g. consist of a steel girder or another part of a building, to which the connecting elements, instead of being poured into concrete as shown, are fastened and anchored in the usual professional manner.
  • the metal connecting elements used are, for example, a tension rod 3, a compression rod 4, which is each provided with a pressure-receiving plate 5, and an element 6 that can be subjected to bending to absorb bending moments.
  • the two building parts 1 and 2 are separated by the joints 7,7 '; Groove 7 schematically shows an insulating element or an element 8 that fulfills another function.
  • This lock is intended to prevent the penetrated, corrosive medium from reaching the unprotected areas of the connecting elements located in the structure.
  • This lock consists, for example, of a flange-shaped collar 11 which, as will be explained in more detail with reference to FIG.
  • barrier 11 has a sealing function and extends the path of the corrosive medium from the entry point 13 to the part of the connecting element which is at risk of corrosion.
  • the design of the barrier as a labyrinth 12 has the additional advantage that the penetration path for the corrosive medium is further extended and the sealing effect is multiplied; in the case of short connecting elements, such as connecting element 4, this can be advantageous.
  • the functioning of such barriers 11, 12 in the sealing is discussed in more detail in the description of FIG. 2.
  • the friction between the casing 10 and e.g. an insulation body 8 is enlarged. This is important because the insulation bodies required today tend to slip on the reinforcement that passes through them, and in turn there is a risk that problems will arise during installation on the construction site.
  • FIG. 2a and 2b show the situation under two different load conditions.
  • Fig. 2a a situation is shown, as it can be given with temperature-related relative displacement between the different parts of a building.
  • a part 2 (not shown in more detail) provided next to a hydraulically bound part 1 of a building is anchored to part 1 with the aid of a connecting element 4 which can be subjected to tension or pressure.
  • the arrow indicates the direction of the load acting on the connecting element.
  • the connecting element 4 is subject to a bend. While the casing 10 seals well on one side due to the increased pressure, a crack 13 has opened on the other side.
  • Fig. 2 b shows the simpler conditions with only tensile or compressive load.
  • the collar 11 presses against the material of part 1 on an annular surface and seals securely.
  • FIGS. 2a and 2b naturally also apply if, instead of the temperature-related stress between adjacent parts of a building, another load, uniform or alternating, acts.
  • the end of the connecting element projecting from the part consisting of hydraulically setting material can be provided with a hook for tensioning or other load cables.
  • the length of the covering in the relevant part of the structure made of hydraulically setting material corresponds at least to the usual covering of reinforcements in concrete.
  • the thickness of the cladding is preferably chosen so that the connecting element that bends under load does not rest on the material of the structural part surrounding the cladding. This means that the clamping point of the connecting element is moved inside the building part.
  • the thickness to be selected thus depends on the characteristics of the connecting element in the individual case, but is preferably in the range between 1 and 3 mm.
