Definitions

  • the invention relates to an injection hose with a Profile strand made of flexible, resilient Material that has a continuous longitudinal channel and at least a continuous, through openings on the bottom communicating with the longitudinal channel, through lateral groove flanks limited and essentially at a slot opening has radially open longitudinal groove, and with a arranged in the longitudinal groove, with holding means in this held across the breakthroughs Sealing cord made of elastic, preferably compressible material.
  • the invention further relates to a method for producing a such injection hose.
  • Injection hoses of this type are mainly used permanent sealing of construction and movement joints used on structures, especially on concrete structures.
  • the in the concreting process Groove inserted injection hose over the longitudinal channel with a curable sealant in liquid or pasty form so pressurized that the Sealant through the openings while lifting off the sealing cord is injected into the joint to be sealed becomes.
  • An injection hose of this type is known (EP 0 522 327 A), in which the holding means for loose sealing cords inserted into the longitudinal grooves by a sock pulled over the profile strand from a thin, liquid permeable or under the Exposure to the material dissolving the injection liquid are formed.
  • DE 94 02 078 U relates to a cover strip with a adapted training. For leakage of injection compound through holes 1 are then bent (under pressure) Cover strips provided. The profile strand has no openings, but a cross channel to the cover strip.
  • the prior art from EP 0 692 584 A is that from DE 94 02 078 U approximately equivalent (insert 7, separating slot 13).
  • the invention is based on the object an injection hose of the type specified Art as well as a process for its production develop, with which the production without functional disadvantage simplified and the handling of the injection hose can be improved.
  • the solution according to the invention is based on the idea that with a suitable shape of the profile strand on the use of a holding stocking without Functional disadvantage can be dispensed with entirely.
  • the opening width of the groove opening is smaller than is the diameter of the sealing cord and that the Holding means through undercuts in the groove flanks the longitudinal groove are formed.
  • the sealing cord seals the Longitudinal channel against liquid access from the outside while them when the longitudinal channel is loaded with liquid sealant under pressure an exit gap for the sealant to the outside without leaving the Longitudinal groove to be displaced. This also ensures that after completing the injection process the passage gap closes automatically, so that the longitudinal channel without liquid entry from the outside can be sucked empty again.
  • a preferred embodiment of the invention provides that the diameter of the sealing cord is larger than that Depth of the undercut longitudinal groove is, so that a Part of the sealing cord inserted in the longitudinal groove protrudes radially beyond the slot opening and through the groove edge is constricted.
  • the groove flanks in the area of their opening side Edges in profile like hooks on the inside of the groove bent. Basically, it is also possible that the groove flanks are dovetail-like for this purpose Form undercuts.
  • Another preferred embodiment of the invention stipulates that at least one other, compared to the Longitudinal channel closed, undercut on its side flanks and provided on the outside open longitudinal groove is in which an elastically flexible, flexible sealing strip made of swellable material under water is arranged positively. With one Sealing strip is achieved that when water enters in a joint of the sealing strips from the concerned Longitudinal groove swells outwards and the joint prevents water penetration seals.
  • the profile strand expediently has a polygonal, preferably triangular profile with a central one Longitudinal channel, on the profile corners of which with the bottom Breakthroughs and with the sealing cords equipped longitudinal grooves are arranged.
  • the closed to the longitudinal channel, with the swellable Sealing strips equipped profile grooves are with this Design expedient in the main arranged flat profile sides of the profile strand.
  • the sealing cords are preferably made of EPDM rubber expediently from a compressible foam rubber manufactured.
  • the under the influence of water swelling sealing strips can be made from a Swelling agents such as urethane resin, polyvinyl alcohol or Acrylic resin mixed rubber exist.
  • the inventive method of a rubber existing profile strand over a longitudinal channel generating Mandrel by inserting the undercut Longitudinal grooves extruded and then vulcanized and cooled, before or during the vulcanization process at least in part of the longitudinal grooves of the Profile strands transported over the mandrel at a distance Bottom openings arranged from each other with material displacement be pushed in. Then be the extruded and cooled profile strand in a pass from the side from a supply roll unwound sealing cords and / or sealing strips fed and pressed into the associated longitudinal grooves. The flexible in this way Finally, the profile strand is transported in batches on transport rollers rolled up and cut to the desired length.
  • the injection hose shown in the drawing is for sealing construction and movement joints in Concrete structures determined. He assigns one with a central one Longitudinal channel 10 provided, in cross section essentially triangular profile strand 12 on the area its corner edges 14 with longitudinal grooves 16 and in the area its side surfaces 18 provided with longitudinal grooves 20 is.
  • the longitudinal grooves 16 communicate via at a distance openings on the bottom arranged from each other 22 with the longitudinal channel 10 and are with sealing cords 24, made of a rubber-elastic, compliant and compressible Equipped with material such as foam rubber.
  • the opening width the groove openings 26 is smaller than that Diameter of the sealing cords 24.
  • the sealing cords 24 reach through the groove openings 26 to the outside and are in the area of Opening gap through the inwardly curved edges 28 of the groove flanks 30 in the manner shown in FIG. 1 constricted.
  • the sealing cords 24 overlap within the longitudinal grooves 16 the openings 22 and seal thereby the longitudinal channel against liquid ingress from the outside.
  • the longitudinal channel 10 below Pressurized with a liquid injection agent so give the flexible sealing cords 24th Passage gap for the injection agent to exit free to the outside without leaving its longitudinal groove 16 to be pushed out.
  • a curable liquid injection agent come, for example, water-miscible, reactive curing synthetic resins, resins based on vinyl esters, Polyurethane resins, fine cement, epoxy resins or the like into consideration.
  • Longitudinal grooves 20 are on the bottom side of the longitudinal channel 10 closed. They have a dovetail shape undercut groove flanks 32 and contain one under the influence of water swellable sealing strips 34, which is positively anchored in the groove is. If there is water ingress, the sealing strip can with a suitable choice of material to a multiple of its Swell volume and one between the profile strand 12 and an adjacent concrete surface formed gap Seal against water penetration.
  • the invention refers to an injection hose designed for the sealing of construction and movement joints in concrete structures is determined.
  • the injection hose points a profile strand 12 made of flexible, resilient Material on a continuous longitudinal channel 10 and has at least one longitudinal groove 16.
  • the longitudinal groove communicates with the floor through openings Longitudinal channel and is with an overlapping breakthroughs Sealing cord 24 made of resilient, compressible material.
  • a special one simple and inexpensive manufacture of the injection hose is made possible by the opening width of the slot openings 26 is smaller than the diameter of the Sealing cord 24, and that the holding means for Holding the sealing cord through undercuts are formed in the groove flanks 30 of the longitudinal groove.
