Definitions

  • the invention relates to a covering device for sealing working joints, in particular concreting joints, with a carrier and an at least partially applied to the carrier coating comprising a bonding agent having a sealing material.
  • Concreting joints or construction joints occur especially in cast-in-situ construction.
  • Working joints in concrete and reinforced concrete constructions, in particular concreting joints, which arise when concreting a second concrete part to an already existing first component often have to be reliably sealed.
  • concreting joints or construction joints must be permanently sealed.
  • the bentonite layer is a barrier. Cracks and voids are captured and sealed by the bentonite.
  • EP 0 922 466 A1 is a sealing element with a water-repellent admixture and / or a water-repellent shell and at least one water-swellable admixture and at least 5-20 mass% Feinstzemente with a Blaine value of 5000 - 15000 cm 2 / g or 5 - 10 mass% calcium hydroxide known.
  • Object of the present invention is to develop a sealing device of the type mentioned in such a way that a secure and permanent sealing of construction joints is possible.
  • a sealing device with the features of claim 1.
  • the sealing material can be securely held on the carrier.
  • the sealing material can be particularly easily introduced into the working joint together with the carrier.
  • the adhesion promoter is first applied to the support and then the calcium hydroxide.
  • the cement and calcium hydroxide may be premixed to form a sealant mixture that can be applied to the primer.
  • the calcium hydroxide added to the adhesion promoter or the cement added produces, under the action of water, the water-insoluble calcium carbonate and thus a very good water-tightness and a good bond between the sealing material and the surrounding concrete. This measure creates a composite seal. The sealing effect is achieved via 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. Without calcium carbonate formation, self-healing is not possible.
  • the simplified reaction equation for calcium carbonate formation is as follows: Ca 2+ + CO 3 2- ⁇ CaCO 3 .
  • the sealing takes place in a physical, chemical and mechanical way.
  • a swelling of the cement paste, which is embedded in the coating occurs.
  • the chemical sealing is carried out by Nachhydrat under the cement paste, which is embedded in the coating matrix and / or by the formation of water-insoluble calcium carbonate.
  • the mechanical sealing takes place by narrowing or blocking the flow path through inorganic or organic fines in the water.
  • the constriction or the blocking of the flow path is carried out by loose Cement particles which are broken out of the cracks during crack formation. Material fatigue is excluded in the sealing device according to the invention, since the sealing is achieved by sintering, in particular, the working joint can be completely sintered.
  • a cement fine cement in particular the flow path of the water can be blocked particularly well. Furthermore, they support the mechanical self-healing process.
  • a particularly good seal can be achieved if the sealing material comprises bentonite and / or quartz sands. With such particles, the mechanical crack closure, especially in the initial phase of penetrating water significantly improved and the flow can be restricted.
  • the adhesion promoter is a plastic dispersion
  • the sealing material can be stored particularly well in the adhesion promoter or attached to the support.
  • the carrier is designed as a carrier plate, it is designed to be particularly durable. The corrosion of the carrier plate can be prevented because the carrier plate is galvanized.
  • the carrier has the coating only on one outer side.
  • the opposite outside is in this case without Coating.
  • the coating can be provided on only one of the large-area outer sides.
  • the coating forms a rough surface on the carrier.
  • the waterway is extended by penetrating water.
  • a particularly good bond between the carrier and the surrounding in-situ concrete can be formed by a rough coating.
  • a claw or a frictional connection with the in-situ concrete can be formed if the surface of the coating is rough.
  • the coating of the carrier and thus the sealing device preferably have no separating property. This ensures a good bond.
  • the coating of the carrier has no tackiness. As a result, can be dispensed with protective strips that must be removed before concreting.
  • the seal can in particular run in two phases. First, by a barrier, z. As the blocking of the flow path through fines, sealed and then by sintering.
  • the sealing of longer joints can be advantageously achieved in that a plurality of carriers abut each other or are arranged overlapping each with one end.
  • a sealing adhesive can be elastic and form a pressure-water-tight bond.
  • the single FIGURE shows a cross section through several concrete parts, between each of which a construction joint is formed.
  • FIG. 1 In the figure , three concrete parts 1, 2, 3 are shown, wherein between each two concrete parts 1, 2, 3, a working joint 4, 5 is present.
  • the sealing device 6 has a carrier 7 formed as a carrier sheet, on which a coating 8 is mounted.
  • the coating 8 consists of a bonding agent, 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 conjunction with water water-insoluble calcium carbonate, which has a good water resistance and produces a good bond to the sealing device 6 surrounding concrete.
  • water can not spread along the sealing device 6.
  • the working joint 5 is sintered by the coating 8.
  • a sealing device 9 is arranged, which extends substantially perpendicular to the working joint 4.
  • the sealing device 9 differs from the sealing device 6 only in that it is not L-shaped in cross-section, but flat.
