Definitions

  • the invention relates to a concrete joint seal used to form a cavity from a tube-like outer skin which is open at both ends and provided with an inner, helical support body, the support body being flexible.
  • Such a concrete joint seal is already known from DE-PS 40 15 418 of the patent seeker.
  • This concrete joint seal which is advantageous in itself, has a large cross section available for the pressing operation and, moreover, the pressing is hardly impeded by the coarse-meshed outer hose remaining in the cavity.
  • the known concrete joint seal can only be produced with a diameter of more than 20 mm.
  • concrete joint seals with such relatively large diameters are generally only required for cement grouting.
  • it is desirable to press synthetic resin instead of cement which is, however, 10 to 15 times as expensive as cement material.
  • the synthetic resin material has the basic advantage that it is extremely thin, and is therefore suitable for sealing even very fine cracks in the concrete.
  • the volume to be filled with synthetic resin before the actual pressing process begins is so large that sealing with synthetic resin is completely uneconomical.
  • the object of the invention is therefore to create a new compression hose with which synthetic resin compression is also possible in a technically and economically sensible manner.
  • the solution to the problem essentially results from the fact that the supporting body with the outer skin can be pulled out after the concrete has hardened and the individual partial spiral areas of the supporting body are spaced apart and that this distance is bridged by the outer skin attached to the partial spiral areas, each between two Partial spiral areas has a circumferential weak point, which withstands the concrete pressure and tears when forces are introduced in the axial direction of the concrete joint seal.
  • the construction of the new concrete joint seal according to the invention on the one hand reliably protects the interior of the compression hose from surrounding, still liquid concrete and, on the other hand, the outer skin tearing into a large number of individual parts (surfaces) when the helix is pulled out does not therefore hinder the pressing of the synthetic resin, because the outer skin and the coil are completely removed from the cavity.
  • the concrete joint seal according to the invention also has the advantage that it can be manufactured with an outer diameter of approx. 10 to 12 mm, as a result of which the dead volume - volume of the cavity in the concrete after removal of the concrete joint seal - compared to the at least 20 mm in diameter exhibiting Prior art concrete joint seal significantly reduced. Therefore, with the concrete joint seal according to the invention, synthetic resin can be pressed instead of cement in an economically sensible manner, which, because of its thin liquid, enables particularly good sealing of, in particular, fine cracks in the concrete.
  • the dead volume can be reduced to a quarter with the same length of the seal. Due to this small dead volume, it is then economically justifiable to use the synthetic resin material, which is 10 to 15 times as expensive, because it also has the technical advantage of sealing very fine cracks in the concrete.
  • the weak points in the outer skin are essentially arranged centrally between the partial spiral areas. This has the advantage that, after the outer skin has been torn, roughly the same size parts are attached to the individual partial spiral areas, which are so small that they do not hinder the pulling out of the spiral from the cavity in the concrete.
  • the helical support body is also reinforced, for example by means of a wire insert.
  • This embodiment basically has the advantage that the helical support body is able to absorb the forces that occur during concreting on a larger scale.
  • the concrete joint seal 10 provided with an outer diameter d has a helical support body 11 and an outer skin 12, which together are able to completely shield an interior 16 of the concrete joint seal 10 during concreting.
  • the support body 11, as well as the outer skin 12, are made of plastic, preference being given to polyethylene and polypropylene, which are easy to recycle.
  • the partial helix areas 13 of the support body 11 are at a distance a from one another, the support body 11 being completely encased by the outer skin 12 to shield the interior 16 of the concrete joint seal 10.
  • the ratio of the distance a of the partial helical areas 13 to the outer diameter d of the concrete joint seal 10 should always be ⁇ 1.
  • reinforcements 14 are also arranged in the support body 11, which e.g. can consist of a wire insert.
  • the outer skin 12 each spanning the distance a between the individual partial coil areas 13 has a linear weak point 15, e.g. in the form of a circumferential notch.
  • This concrete joint seal 10 is now installed as follows: First, the hose-like concrete joint seal 10 is fastened to the already hardened concrete of the first section in the concrete joint before the concrete of the second section. The end pieces of the concrete joint seal 10, not shown, are guided through the formwork to the outside. After hardening of the second section of the concrete, the concrete joint seal 10 can be removed altogether, so that no remaining constituents of the concrete joint seal 10 can hinder the pressing process.
  • a tensile force is introduced at an end of the seal 10 which is led outward from the formwork.
  • the outer skin 12 is first subjected to a force acting in the axial direction x of the concrete joint seal 10.
  • the outer skin 12 tears in the region of the weak points 15.
  • the helical support body 11 is pulled apart so far by the tensile force that is introduced that its diameter gradually decreases.
  • the outer skin sections fastened to the partial spiral regions 13 detach from the inner wall of the concrete cavity.
  • the support body 11 can then be pulled out of the cavity in a simple manner.
  • a compression channel is then available, the cross section of which corresponds to the previous cross section of the concrete joint seal 10.
  • the dead volume to be filled before the actual pressing process is significantly smaller due to the small diameter, and the pressing, in particular of plastic, is not hindered by any parts of the concrete joint seal 10 remaining in the cavity.
