Definitions

  • the invention relates to a method for sealing construction and movement joints in concrete structures, in which a profile strand formed as a joint tape or injection hose is made of elastomeric material that is at least partially swellable on its surface with water absorption on a firm, possibly uneven joint boundary surface by means of a paste-like adhesive is glued on and covered with fresh concrete forming a second joint boundary surface after hardening.
  • Swellable joint tapes are used when concrete components cannot be manufactured in one concreting section.
  • the tightness of a construction joint can also be achieved by installing injection hoses.
  • the injection hoses are inserted approximately in the middle of the construction joint during formwork or reinforcement and attached to the reinforcement.
  • the injection hoses are sealed from the outside against the penetration of cement paste and withstand the pressure of the fresh concrete.
  • liquid synthetic resin is pressed into the hose.
  • the tube is sized so that the synthetic resin in the field of construction joint escape while len the joint gap, missing Stel ⁇ and fill cracks and can seal permanently.
  • the non-existent on the surface of the profile strand ter water absorption swellable material ensures that water penetration is prevented by swelling of the material in question.
  • the profile strand is fastened on this side with a thickly applied pasty adhesive. Since the adhesive covers at least a part of the swellable material on the relevant broad side surface of the profile strand, the swellable material cannot develop its full effect at this point when water enters, so that leaks can occur.
  • the object of the invention is to develop a method of the type specified at the outset which, despite simple handling during construction, ensures reliable joint sealing against water penetration.
  • the solution according to the invention is based above all on the idea that the profile strand with a non-swelling capable surface part is glued to the fixed joint boundary surface using an adhesive swell which swells under water. Because of its swellability, the entire adhesive strand thus contributes to increased sealing in the event of water ingress, while the structure of the profile strand as such on the side of the fixed joint boundary surface is simplified by eliminating the swellable material.
  • the strand of adhesive expediently consists of a one-component adhesive which cures with the absorption of water or oxygen and is mixed with a swelling agent.
  • a one-component synthetic resin preferably based on epoxy, polyurethane or polyester can be used as the adhesive.
  • the swelling agent can consist, for example, of a urethane resin, a polyvinyl alcohol or acrylic resin.
  • the profile strand for use in the method according to the invention advantageously has a polygonal, preferably triangular or quadrangular cross section, at least on one of its side surfaces it is provided or equipped with a longitudinally continuous layer of a material which swells under water absorption and is swell-free on a second side surface .
  • It suitably has a Grundpro ⁇ filstrang of elastomeric, preferably kautschukelastischem material having at least one open-edged on one of the side surfaces of the groove for receiving quellfä- material. It has proven to be particularly advantageous if a strand of material made of the swellable material is inserted into the open-edged groove, preferably embedded in it by coextrusion.
  • the basic profile strand can also be provided with at least one continuous hollow channel.
  • this hollow channel has to reduce swelling forces in the case of a profile strand used in the manner of a joint tape and to prevent displacements within the concrete.
  • the hollow channel can be drilled with a large number of spaced-apart transverse bores which can be opened like a valve under the action of an internal pressure. After the concrete has hardened, the hollow channel can be pressurized with a liquid or pasty, hardenable sealant or synthetic resin for sealing purposes.
  • the cross bores can be closed in a valve-like manner by at least one closing strand made of elastomeric material embedded in an undercut groove of the grid profile.
  • a profile strand that can be used as a joint tape expediently has an essentially rectangular basic profile, one broad side surface of which has a layer swellable material coated and the other broad side surface is uncoated.
  • the two narrow side surfaces of the rectangular basic profile strand are also expediently coated with swellable material.
  • Fig. 1 shows a section through a construction joint
  • Fig. 2 shows a section through a construction joint of a concrete structure with a profile strand designed as an injection hose.
  • a base plate 10 made of concrete and a wall 12 made of concrete are provided, which were concreted in two successive concreting sections, so that a construction joint 14 has formed between them.
  • the construction joint 14 is sealed by a profile strand 16 designed as a joint tape, while in the embodiment according to FIG. 2 a profile strand 18 designed as an injection hose is provided.
  • the profile strand 16 according to FIG. 1 has a rectangular cross section. It consists of a basic profile Strand 20 made of rubber-elastic material, which has a plurality of hollow channels 22 aligned parallel to one another and is coated on its one broad side surface 24 and the narrow side surfaces 26 with a material 28 which can swell under water absorption. The material layer 28 is missing on the other broad side surface 30.
  • the liquid concrete for pouring the floor slab 10 is poured into an appropriate formwork and brought to harden. Then the profile strand 16 with its uncoated broad side surface 30 is glued to the uneven joint boundary surface 34 of the base plate 10 with the aid of a pasty adhesive 32 which is capable of swelling while absorbing water. The unevenness in the joint delimitation surface 34 is compensated for by the adhesive 32.
  • the wall 12 is concreted in a second concreting section and the profile strand 16 is poured with liquid concrete, so that a second joint boundary surface 36 is formed.
  • the profile strand is now completely surrounded by swellable material under the influence of water, so that the joint is effectively sealed against the ingress of water.
  • the profile strand 18 designed as an injection hose has an essentially triangular cross section
  • Er contains a basic profile strand 38 with a central hollow channel 40 and with longitudinal grooves 44 arranged in the area of its corner edges 42.
  • the longitudinal grooves 44 communicate with the hollow channel 40 via transverse bores 46 arranged at a distance from one another and are made with a sealing cord 48 made of a rubber-elastic, flexible and compressible material, such as foam rubber.
  • the opening width of the longitudinal grooves is smaller than the diameter of the sealing cords 48.
  • the sealing cords 48 Since the groove depth is also smaller than the diameter of the sealing cords 48, the sealing cords 48 reach out through the groove openings and become inward in the area of the opening gap curved edges 50 of the groove flanks constricted. The sealing cords 48 overlap the transverse bores 46 within the longitudinal grooves 44 and thereby seal the hollow channel 40 against the ingress of liquid from the outside. If, however, the hollow channel 40 ⁇ acted upon under pressure with a liquid injection means, so enter the yieldable sealing cords 48 pass-through slots for the exit of the injection medium exposed to the outside, without leaving its longitudinal - to be forced out 16 nut.
  • suitable curable liquid injection agents are water-miscible, reactive-curing synthetic resins, vinyl ester-based resins, polyurethane resins, fine cement, epoxy resins or the like.
  • Longitudinal grooves 52 arranged in the line 38 are closed toward the hollow channel 40. They contain one under the Exposure to water-swellable sealing strips 54 which are integrally connected to the basic profile strand 38.
  • the basic profile strand 38 and the sealing strips 54 are expediently produced and connected in the coextrusion process. When water enters, the sealing strips 54 can swell to a multiple of their volume and seal a gap formed between the profile strands 18 and an adjacent joint boundary surface against water penetration.

Abstract

L'invention concerne un procédé permettant d'étanchéifier des joints de construction et de dilatation. L'étanchéification s'effectue à l'aide d'un cordon profilé (16, 18) se présentant sous forme de bande couvre-joint ou de flexible d'injection, réalisé en matériau élastomère dont la surface peut gonfler au moins partiellement par absorption d'eau. Le cordon profilé (16, 18) est collé sur une surface périphérique de joint (34) solide éventuellement inégale à l'aide d'un adhésif (32) et est recouvert après durcissement de béton frais formant une seconde surface périphérique de joint (36) solide. Afin d'obtenir une étanchéité de joint fiable, le plus simplement possible, il est prévu selon l'invention de coller le cordon profilé à partie superficielle sans pouvoir gonflant, sur la surface périphérique de joint (34) solide, à l'aide d'un cordon d'adhésif (32) qui gonfle par absorption d'eau.
