Abstract

In a method for installing a firestop device ( 14 ) or insulation having a firestop effect, on a line ( 12 ) or pipe, whereby the firestop device ( 14 ) or the insulation having a firestop effect is placed, especially wrapped, completely around the line ( 12 ) or pipe, in the circumferential direction (U), it is provided that a flexible adhesive tape ( 16 ) containing heat-resistant fibers ( 18 ) in its lengthwise direction (L) is wrapped in the circumferential direction (U) of the line ( 12 ) or pipe completely around the firestop device ( 14 ) or the insulation having a firestop effect.

First claim

What is claimed is:

1. A method for installing a firestop device or insulation on a line or pipe, comprising:
placing the firestop device or the insulation completely around the line or pipe in the circumferential direction; and
wrapping a flexible adhesive tape containing heat-resistant fibers in a lengthwise direction of the tape in the circumferential direction of the line or pipe completely around the firestop device or the insulation.

2. The method as recited in claim 1 wherein the firestop device or insulation includes insulation having a firestop function.

3. The method as recited in claim 1 wherein the placing includes wrapping the firestop device or insulation.

4. The method as recited in claim 1 wherein the adhesive tape is wrapped with at least two complete windings around the firestop device or insulation.

5. The method as recited in claim 4 wherein the windings of the adhesive tape overlap, at least in certain sections.

6. The method as recited in claim 4 wherein the fibers of the individual windings are on top of each other or parallel to each other, at least in certain sections.

7. The method as recited in claim 4 wherein the fibers of the individual windings cross over each other, at least in certain sections.

8. A firestop module for wrapping a line or a pipe, comprising:
a firestop device or insulation;
an adhesive tape including heat-resistant fibers running in a lengthwise direction of the tape.

9. The firestop module as recited in claim 8 wherein the firestop device or insulation is made, at least partially, of an ash-forming, intumescent and/or ablative material.

10. The firestop module as recited in claim 8 wherein the adhesive tape has a support film as well as an adhesive layer.

11. The firestop module as recited in claim 10 wherein the support film is made of PVC.

12. The firestop module as recited in claim 8 wherein the heat-resistant fibers include glass fibers.

13. The firestop module as recited in claim 8 wherein the firestop device or insulation includes insulation having a firestop effect.

14. A firestop module for wrapping a line or a pipe and produced by using the method as recited in claim 1 , comprising:
the firestop device or insulation; and
the adhesive tape including the heat-resistant fibers running in a lengthwise direction of the tape.

15. The firestop module as recited in claim 8 wherein the heat-resistant fibers extend with a length sufficient to extend completely around the line or pipe.

16. The firestop module as recited in claim 8 wherein the heat-resistant fibers run exclusively in the lengthwise direction.

17. The firestop module as recited in claim 8 wherein the tape further includes further heat-resistant fibers arranged perpendicular to the lengthwise direction to form a mesh with the heat-resistance fibers.

18. The method as recited in claim 1 wherein the wrapping results in the heat-resistant fibers extending completely around the line or pipe.

19. The method as recited in claim 1 wherein the heat-resistant fibers run exclusively in the lengthwise direction.

20. The method as recited in claim 1 wherein the tape further includes further heat-resistant fibers arranged perpendicular to the lengthwise direction to form a mesh with the heat-resistance fibers.
