Precompressed Sealing Tape

a sealing tape and compression technology, applied in the direction of flexible covers, building components, instruments, etc., can solve the problems of large space occupied by the sealing tape on both sides, unsuitable long-term use of the overall sealing element, and only in relatively narrow widths, so as to achieve effective deformation of the sealing tape, improve the sealing effect, and improve the flexural strength

Benefits of technology

The solution allows for wider sealing tapes with improved sealing properties and thermal insulation, minimizing deformation and space occupation, while being easy to handle and apply, with the strip-like element providing enhanced flexural strength to maintain the foam's shape and ensure effective sealing.

Problems solved by technology

In the case of these known sealing tapes, however, it is disadvantageous that they can be produced only in relatively narrow widths, because otherwise the recovery force of the precompressed sealing tape produces an oval-to-round shape inside the wrapping, which is unsuitable for installation.
These embodiments suffer from the disadvantage that the stiff layer remaining in the joint does not meet high demands on thermal insulation, nor does it provide high sealing values, and therefore the overall sealing element is unsuitable for long-term use.
The problem with this design is to be found in particular in the large amount of space which the sealing tape occupies on both sides.

Embodiment Construction

[0031]In some cases, the foam strips, wrappings, adhesive tapes, strip-like elements, strip-shaped elements and cover sheets are shown in the drawings as if they were a certain distance apart, so that the individual elements which form the sealing tape can be clearly distinguished from each other. In reality, these elements lie directly on top of each other.

[0032]FIGS. 1-6 show a foam strip 2, which, in the present example, has a rectangular cross section, is partially surrounded by a sheet-like wrapping 4, and is held in a precompressed state. Foam strip 2 can be made of any desired open-cell or closed-cell soft foam, such as polyurethane or polyethylene, and can be impregnated to delay its recovery. A multi-layer arrangement of several different foam materials laminated onto each other is also conceivable, as is the arrangement of an impregnated foam layer on or next to a foam layer which is not impregnated. Different foam layers can be arranged adjacent to each other especially i...

Abstract

The precompressed sealing tape for sealing a joint has an elastically reexpandable foam strip, a wrapping, which at least partially surrounds the foam strip, and a strip-shaped element, which is made of stiff foam. The strip-shaped element is arranged in an area of the first transverse surface of the foam strip. A fastening means for attaching the strip-shaped element to a building component is arranged in an area of the strip-shaped element. A first section of the wrapping is arranged between the first transverse surface of the foam strip and the strip-shaped element.

Description

RELATED APPLICATIONS[0001]This application is a divisional of U.S. patent application Ser. No. 12 / 728,808, filed Mar. 22, 2010, now U.S. Pat. No. ______. The entire contents of such application is incorporated herein by reference. This application also claims priority based on European patent application EP 09 178 899.2, filed Dec. 11, 2009.FIELD OF THE INVENTION[0002]The invention relates to a precompressed sealing tape for sealing a joint such as that between a frame profile of a window or a door and the wall of a building.BACKGROUND OF THE INVENTION[0003]A precompressed sealing tape, which consists of an elastically reexpandable foam strip of rectangular cross section, which, in the compressed state, is completely surrounded by a wrapping formed by a sheet of plastic, is known from EP 1 131 525 B1. The sheet of plastic forms a tear-off tab extending in the longitudinal direction of the sealing tape, for which purpose the sheet is bonded to itself to form a predetermined tear site...
