4. The sealing element according to claim 1, wherein the sealing tape (1) comprises at least one opening (13) of a size and shape to allow for inserting a pipe element so that the pipe element is fixed therein.

5. The sealing element according to claim 4, wherein the fabric layer (2) comprises at least one recess (23) respectively arranged at each at least one opening (13) of sealing tape (1) so as to surround the opening (13) of sealing tape (1).

6. The sealing element according to claim 1, wherein the fabric layer (2) comprises a longitudinal cut-out portion (231) extending along the entire sealing tape (1).

7. The sealing element according to claim 1, wherein the sealing tape (2) comprises a first preformed bending edge portion (14) extending longitudinally along the entire sealing tape (1).

8. The sealing element according to claim 7, wherein the sealing tape (2) comprises a second preformed bending edge portion (141) extending square to the first preformed bending edge portion (14).

9. The sealing element according to claim 1, wherein the sealing tape (1) has a plurality of edge openings (15) arranged along the outer edge (11, 12) of the sealing tape (1).

10. The sealing element according to claim 1, wherein the sealing tape (1) comprises an elastic rubber material.

11. The sealing element according to claim 1, wherein fabric layer (2) comprises polyester fabric material.

Description

(1) Further advantageous aspects of the sealing element according to the invention become apparent from the following description of embodiments of the invention with reference to the accompanying drawings in which:

(2) FIG. 1 shows a sealing strip;

(3) FIG. 2 shows the sealing strip of FIG. 1 with torn off outwardly protruding portions of the fabric layer;

(4) FIG. 3 shows the backside of the sealing strip of FIG. 1;

(5) FIG. 4 shows a sealing sleeve;

(6) FIG. 5 shows a sealing corner;

(7) FIG. 6 shows a sealing strip of FIG. 1 having a plurality of edge openings.

(8) In FIG. 1, the sealing element according to the invention is shown as a sealing strip from the top perspective. The shown sealing element can be used for a waterproof sealing of junctions at structural elements of a building. The sealing element has a sealing tape 1 and a fabric layer 2. Sealing tape 1 has a waterproof surface. Fabric layer 2 is of a material which allows for a sealing compound to adhere thereto and is fixed to sealing tape 1 in a manner so that a portion of fabric layer 2 projects outwardly from an (over an) outer edge 11, 22 of sealing tape 1. The fabric layer 2 comprises a first perforation 221 and a second perforation 222 as tear line portions. The first perforation 221 is arranged at a first outwardly projecting portion of the fabric layer 211 so as to extend along a first outer edge 11 of the sealing tape 1. The second perforation 222 is arranged at a second outwardly projecting portion of the fabric layer 212 so as to extend along a second outer 12 edge of the sealing tape 1. This allows forming a sealing element by tearing of the first and second outwardly projecting portions of the fabric layer 211, 212 and thus having no material of fabric layer 2 projecting outwardly from the outer edge of sealing tape 1, as shown in FIG. 2. The sealing element without such an outwardly projecting fabric layer can be processed with a sealing compound of a high viscosity without occurring problems like wrinkles etc.

(9) In FIG. 3, the backside of the sealing strip of FIG. 1 is shown. The sealing tape (not shown) is fully covered by the fabric layer 2.

(10) According to FIG. 4, the sealing element is formed as sealing sleeve. The sealing sleeve, as well, comprises a sealing tape 1can only be seen in the recess 13 of the fabric material 2made of an elastic rubber material and a fabric layer 2 having a single circular extending perforation 22. Sealing tape 1 comprises two openings 13 through each of which a pipe can protrude for being sealed by the sleeve. Fabric layer 2 has two recesses 23 surrounding the two openings 13. The perforation allows for separating the outer portion of the fabric layer 2 to which a sealing compound (not shown) can adhere.

(11) According to FIG. 5, the sealing element is formed as sealing corner. The sealing corner has a sealing tape 1 which comprises a first preformed bending edge portion 14 and a second preformed bending edge portion 141 extending longitudinally along the entire sealing tape 1. The first and second bending edge portions are squarely arranged so as to fit into the corner of a room.

(12) In FIG. 6, the sealing element is a sealing strip having a plurality of edge openings 15 arranged along the outer edge 11, 12 of the sealing tape 1.
