Definitions

  • the invention relates to a sealing device for sealing construction joints, in particular of concreting joints, with a carrier and at least one coating applied in sections to the carrier, which a Has sealing material.
  • Concreting joints or construction joints occur particularly in in-situ concrete construction. Construction joints in concrete and reinforced concrete structures, in particular Concreting joints, which when concreting a second concrete part to an already existing first component arise often have to be reliably sealed will. Especially with waterproof concrete structures concreting joints or construction joints must be permanently sealed.
  • the object of the present invention is to provide a sealing device of to the point of continuing education to the extent that a safe and permanent sealing of construction joints is made possible.
  • a sealing device of the type mentioned at the outset in which the coating comprises an adhesion promoter and the sealing material comprises cement and / or calcium hydroxide.
  • the sealing material can be securely held on the carrier by the adhesion promoter. In this way, the sealing material can be introduced into the construction joint together with the carrier in a particularly simple manner. It is conceivable that first the adhesion promoter is applied to the carrier and then the calcium hydroxide is applied. In particular, the cement and the calcium hydroxide can be mixed beforehand so that a sealing mixture is created that can be applied to the adhesion promoter. Furthermore, it is conceivable to already mix the sealing mixture or the sealing material with the adhesion promoter and then to apply the mixture to the carrier.
  • the calcium hydroxide added to the adhesion promoter or the added cement creates water-insoluble calcium carbonate under the action of water and thus very good water tightness and a good bond between the sealing material and the surrounding concrete. This measure creates a bonded seal.
  • the sealing effect is achieved through the bond (enlargement of the surface) and subsequent self-healing of the concrete joint.
  • Calcium carbonate formation plays a major role in the self-healing of cracks or construction joints in in-situ concrete. Self-healing is not possible without calcium carbonate formation.
  • the simplified reaction equation for calcium carbonate formation looks like this: Ca 2+ + CO 3 2- ⁇ CaCO 3 .
  • the sealing is carried out in a physical, chemical and mechanical way.
  • the chemical Sealing is done by rehydrating the cement stone that is in the Coating matrix is embedded and / or by the formation of water-insoluble calcium carbonate.
  • the mechanical seal takes place by narrowing or blocking the flow path inorganic or organic fines in the water. In particular, the Narrowing or blocking of the flow path by loose Cement particles that broke out of the crack banks when the crack formed will.
  • a material fatigue is with the invention Sealing device excluded because the seal is sintered is achieved, in particular, the construction joint can be completely sintered will.
  • cement fine cement As Cement fine cement, ultra-fine cement or microcement is provided. With Such fines can in particular be the flow path of the water be blocked particularly well. They also support the mechanical Self-healing process.
  • a particularly good seal can be achieved if the sealing material Includes bentonite and / or quartz sands. With such particles can the mechanical tear especially in the early stages of penetrating water significantly improved and the flow be restricted.
  • the sealing material can be stored particularly well in the adhesion promoter or attach to the carrier if the adhesion promoter is a plastic dispersion, in particular is a latex dispersion.
  • the adhesion promoter can be a Resin, epoxy resin, thermoplastic or crosslinkable synthetic resin, latex, one Latex emulsion, a cement adhesive mortar, a natural or synthetic rubber be.
  • the adhesion promoter can be elastic or rigid.
  • the carrier is designed as a carrier plate or carrier plastic, it is especially durable. Corrosion of the carrier plate can be prevented if the carrier plate is galvanized. Alternatively, the carrier plate be black (oxidized).
  • the carrier plastic can be made of PVC, for example be trained.
  • the carrier has the coating on only one Has outside.
  • the opposite outside is without in this case Coating.
  • a strip-like carrier i. H. one flat, thin-walled carrier, can be applied to just one of the large-area
  • the coating may be provided on the outside.
  • the coating on the carrier is rough Surface. By doing this, the waterway of penetrating water extended. Furthermore, through a rough Coating a particularly good bond between the carrier and the surrounding in-situ concrete. In particular, a Claws or a frictional connection with the in-situ concrete are formed if the surface of the coating is rough.
  • the coating preferably has of the carrier and thus the sealing device no separating property. This ensures a good bond. It is also advantageous if the coating of the backing has no tackiness. This can result in Protective strips, which have to be removed before concreting, are dispensed with will.
  • the sealing can in particular take place in two phases. First, a barrier, e.g. B. blocking the flow path by fine materials, sealed and then by sintering.
  • the sealing of longer joints can advantageously be achieved in this way be that several carriers abut against each other or with one each Are arranged overlapping end. To prevent the If water penetrates the overlapping area or in the abutment area, it is advantageous to glue the carrier with a sealing adhesive. In particular, can the sealing adhesive must be elastic and a pressure-water-tight bond form.
  • the single figure shows a cross section through several concrete parts, between each of which a construction joint is formed.
  • a sealing device 6 which is essentially L-shaped in cross section is introduced into the concrete parts 1, 2.
  • the sealing device 6 has a carrier 7 designed as a carrier plate on which a coating 8 is applied.
  • the coating 8 consists of an adhesion promoter in which a sealing material, in particular cement or calcium hydroxide, is incorporated.
  • a seal is formed on the one hand by the carrier 7 itself.
  • the coating 8 in connection with water forms water-insoluble calcium carbonate, which has good water tightness and creates a good bond with the concrete surrounding the sealing device 6. Thus, water cannot spread along the sealing device 6 either.
  • the coating 8 sintered the construction joint 5.
  • a sealing device 9 is arranged, which extends essentially perpendicular to the construction joint 4.
  • the sealing device 9 differs from the sealing device 6 only in that its cross-section is not L-shaped, but rather flat.
