Definitions

  • the present invention relates to a method for sealing a building joint between an existing one Old concrete construction and an attached freshly poured new concrete construction, whereby for sealing a joint tape is used. Furthermore concerns the invention a joint tape for sealing a Structural joint, according to the preamble of claim 7.
  • WO 00/04247 is a joint tape for the above known use.
  • This well-known joint tape is T-shaped in cross-section, with the T-beam forms a back part of the joint tape.
  • this Back part is the joint tape on an existing one Old concrete construction attachable.
  • the back part using an adhesive bed flat on the old concrete structure glued on, the adhesive for example is a synthetic resin.
  • the back part using fasteners such as screws or Nails to be connected to the old concrete structure.
  • the fasteners are preferred with continuous, separate pressure bars made of metal highlighted.
  • a bridge projects from the middle of the back, in the freshly poured new concrete construction the casting of which is embedded.
  • joint tape for a water-impermeable Sealing of individual sections of concrete between these occurring joints
  • the joint tape is a profile made of an elastic material, like thermoplastic, and with in provided in its longitudinal direction upstanding webs is. Furthermore, it is for combined use with injection hoses or volume changing Sealing cords with at least one integrally molded Holder for the injection hoses or sealing cords educated. Because of its shape, too this joint tape only for sealing between immediately successively manufactured concreting sections be used because it is in the individual concrete areas must be poured.
  • a method for sealing a building joint between an existing old concrete structure and one fresh concrete to be poured onto it specify, for sealing a joint tape is used. Furthermore, a joint tape for Use created in the inventive method become.
  • the joint tape in both the old concrete construction as well as in the new concrete construction mechanically firm and at the same time sealingly anchored.
  • the groove for the joint tape in the old concrete construction is freshly milled, the groove is after its manufacture smooth and clean and therefore easy to use for a firm, tight and permanent connection with the filling compound.
  • the groove is included during filling the filling compound freely accessible and clearly visible, so that a complete filling of the groove with the filling compound can be easily checked with the eye.
  • the filling the groove can, for example, by filling the Filling compound or by injecting the filling compound Cartridges or other suitable storage containers.
  • An alternative embodiment of the method provides that after milling the groove, the joint tape with its first Longitudinal edge is inserted into the groove and that then the groove is filled with the filling compound.
  • the procedure is the insertion of the first longitudinal edge of the joint tape in the groove easier because still there is no filling compound in the groove. Filling the remaining one

  • the joint tape Due to its asymmetrical shape, the joint tape needs only one groove on the side of the old concrete structure with a limited depth that is still acceptable Effort can be produced on the construction site; on his other The joint tape is in the freshly made side New concrete construction embedded sufficiently far, so that on this side the tightness in the known way is achieved and guaranteed. The tightness against the passage of water is reduced the side of the old concrete structure through the combination guaranteed by joint tape and filling compound, whereby for the Tightness here also a relatively small depth of the groove is sufficient.
  • the joint tape is provided that on the first longitudinal edge and / or on the second longitudinal edge (each) at least one injection channel and / or Holding means for holding (in each case) at least one injection hose are provided.
  • the injection channel or the one possibly attached to the holding means Injection hose can either be used to introduce the filling compound used in the groove when attaching the joint tape or he can later, if necessary should be used to inject a sealant become.
  • This sealant injection is e.g. then required if the concrete is in the vicinity of the groove the old concrete construction and / or in the new concrete construction should be additionally sealed or if the joint is found to be permeable to moisture becomes.
  • an injection channel and an injection hose can be provided on the joint tape. It can then e.g. the injection channel or the injection hose first for filling the groove with the filling compound or for a first sealing injection can be used; for a later one Injection of a sealant is then still available injection hose or channel not in use yet Available.
  • the injection hose holding means mentioned are preferred through one or more continuously or in sections integrally formed clamping grooves.
  • the injection hose can be simple if necessary be snapped into place by hand. If not a clamping groove is used to hold an injection hose, ensures that the joint tape is securely anchored in the filling compound filling the groove or in the freshly cast Concrete.

This can be both a broadening or narrowing of the joint as well as parallel displacements of the concrete structures relative to each other from hollow middle part of the joint tape without destruction in one sufficient dimensions can be traced
  • joint tape is on the top and / or bottom of the joint tape (each) an upright, perpendicular to the joint tape level, Mounting and sealing flange running in the longitudinal direction of the joint tape provided that in the installed state of the Joint tape on the end face of the old concrete structure is applied.
  • This flange, or in pairs these flanges ensure that the Joint tape on the old concrete structure, especially if the procedure in its variant with the subsequent Introducing the filling compound is applied.
  • the mounting and sealing flange can be spaced at a grid Breakthroughs are appropriate through which selective connection means, especially nails or screws, to fix the joint tape at his Laying can be introduced into the old concrete structure.
  • the second longitudinal edge is useful of the joint tape with a surface enlarging and friction-increasing structure and / or from the joint tape level upward and / or downward projecting anchoring webs Mistake.
  • the joint tape can be made from an elastic-flexible Material or from several materials different Properties exist.
  • the materials have to not just be plastic; as known per se, can part of the joint tape also through a metal profile, e.g. a sheet metal strip.
  • the joint tape In order to be able to produce the joint tape inexpensively, is it is preferably extruded in one piece from a material or co-extruded from multiple materials.
  • a preferred material for the joint tape is due to its favorable mechanical and chemical properties and its low cost polyvinyl chloride (PVC).
  • the hardness or strength of the first is preferred Longitudinal edge is higher than the hardness or strength of the second longitudinal margin. This ensures that the joint tape itself when it is pressed into the filling compound the joint is not accidentally deformed and that after the Hardening of the filling compound is firmly anchored in it. at the same time the joint tape remains sufficient in its remaining parts elastic and flexible to handle relative movements follow between old and new concrete construction to be able to.
  • Figure 1 of the drawing shows the edge area of the right Old concrete construction 7 and the one facing it on the left Edge area of a new concrete construction 8, in the present Case two sole plates.
