The present invention relates to a sealing tape which is suitable for smelling connections, for example Concrete (prefabricated parts or parts cast on the construction site), brickwork or other masonry, artificially constructed or natural stone, iron or MB-Metallan, softened or hard plastics, wood or others To seal building materials or components against the penetration of water or moisture

It is common practice to make such connections with the help of a sealant or putty or by means of a finished one Tape, which can be flexible or rigid and possibly compressible, to seal the application of putty or sealing compounds is a lengthy process · The well-known prefabricated, compressible Sealing tapes show "compression shrinkage" over time, which increases the ability of the compressed to expand Material after a certain aging

Because of this, there is passage of water or moisture between the Sealing strips and the adjoining walls of the connection ·

It is also known that most building materials, especially concrete, are irregular on the surface; the well-known prefabricated sealing tapes tend to be to bridge minor bumps on the surface of the walls at the junctions, creating water and moisture can easily penetrate.

With the present invention, a sealing tape is now proposed that produced in any length and may be either during or used according to the actual construction, the associated with the use of putty or sealing compounds lengthy procedures avoided and the drawbacks of the _known} compressible sealing strip practically be completely overcome _a

The task of the coating made of practically waterproof, In practice, pressure-sensitive adhesive consists of the penetration of the vase through the foam core and to prevent between the core and the agrensenden surfaces and on the other hand the tape with the adjoining surfaces connect to. In the latter respect, the sealing tape can be used due to its self-adhesive properties a prefabricated component made of concrete or another material prior to assembly with the adjacent part be attached to the seam, whereby it can also be easily attached to sloping surfaces, by simply pressing it tight by hand · As the sealing tape is easy to compress due to the cellular inlay on the other hand, it can also be done after the components have been assembled by pressing them together and pushing them in

The novel sealing tape preferably has a circular cross-section, but may also be any other, for example, a rectangular cross section sawn sit ψ. The thickness of the outer coating depends to some extent on both the dimensions of the finished tape and the type of pressure sensitive adhesive used. As a rule, it can be stated that the cross-sectional area of the tape corresponds approximately to that of a circle with a diameter of 0.6 to 15 cm, for example 2.5 cm in diameter, while the thickness of the tubular coating fluctuates between ₀ 08 and 2.5 cm, E.g. it can be 0.3 cm «

The accompanying drawing serves to explain the present invention; it is a true-to-length drawing of a typical sealing tape according to the invention. The compressible cellular core 1 of the tape, which consists, for example, of natural foam rubber, has a diameter of 2.5 cm and is surrounded by a layer of pressure-sensitive adhesive, e.g. a bitumen / rubber mixture 0.3 cm thick, _{or the like}
