Definitions

  • the invention relates to an arrangement and a method for sealing Joints in buildings, in particular of expansion joints in an external facade.
  • Such joints can, for example, in a masonry or in a Concrete wall of a building, for example, at a transition from old and new walls, in an extension, or between long ones monolithic Baulöcken arise or be provided.
  • joints are often provided, in particular expansion joints.
  • Expansion joints are said to expand or contract the building materials compensate due to temperature fluctuations.
  • the joint profiles as well as the U-shaped Sealing profile are at least partially for the isolation of the expansion joint filled with an insulating material.
  • the in DE 197 19 501 A1 described seals for expansion joints is relatively complex in of manufacture and installation.
  • a dirty cleaning edge be visible along the webs or the joint edge.
  • a possibility for easier sealing of expansion joints in buildings is the use of a flexible band in loop form, such as in DE 40 20 333 A1 describe.
  • the fabric insert extends beyond the joint, the nitrile rubber coating only up to the edge of the joint is enough.
  • On the supernumerary Fabric tape is a reinforcing strip on each side of the joint Fiberglass strands laid, which is bent into the joint. The reinforcing strip is placed in a putty or in the plaster and the Joint seal thereby secured.
  • An object of the invention is, therefore, an arrangement and a method for the sealing of joints in structures, in which the aforesaid Disadvantages in the prior art at least partially overcome or at least diminished.
  • the arrangement according to claim 1 for sealing joints in structures, in particular of expansion joints in an external facade comprises at least one flexible sealing tape for sealing the joint, and at least one sealing profile, wherein the sealing profile comprises a first portion which is one of the loop formed in the joint at least partially loop fills, and wherein the sealing profile comprises a second portion, the the joint covers and at least one joint edge at least partially overlaps.
  • the joint in particular the expansion joint, is preferably an expansion joint in a masonry or in a concrete wall or in a Exterior facade of a building, for example in a cladding made of thermal insulation panels.
  • Be several pieces of sealing tape in one Groove used so it is particularly advantageous if the sealing profile is performed consistently at the interfaces of Abdichtb sections. are more pieces to use sealing profile, so it is also advantageous if the interfaces of the sealing profiles to the interfaces of Sealing tapes are arranged offset.
  • the first section of the sealing profile may vary depending on the material used be executed as a solid profile, so that the joint or the loop of the Sealing bands in their width and / or depth through the first section is completely filled out. Furthermore, the first section may have a profile or have a cross section of the joint or the loop only partially fills. However, the first section is basically in its width or Its diameter is designed so that it has the joint in its entire width spans, that means the width or the diameter of the first Section always corresponds approximately to the joint width or the joint diameter, so that the sealing profile is held firmly in the joint. In the Cavities in the joint may introduce additional thermal insulation material be to improve the insulation of the joint.
  • An idea underlying the invention is thus, by the insertion a sealing profile in the joint, in particular in the loop of a flexible Sealing bands that at least partially fill the loop and the joint overlapping covers, to create a very simple joint seal, the especially the penetration of moisture into the joint safely prevented and at the same time has an insulating effect.

  • Another advantage of the arrangement according to the invention is that unclean Cleaning edges or color deposits on the sealing tape of the Sealing profile can be covered, as the second section on the Joint edges rests and overlaps.
  • joints with very large Fluctuations in the joint width are sealed.
  • the arrangement for Sealing joints is so very flexible and due to the simple construction also relatively inexpensive.
  • a main advantage of the method according to the invention is, moreover, that the individual parts of the arrangement with very simple means and very can be mounted quickly in or on the joint.
