Description

The invention relates to a joint-sealing strip according to the preamble of claim 1, a method for providing a joint-sealing strip according to the invention according to claim 13 and an injection device according to claim 18.

When installing a frame component, in particular a window, in a soffit, inter alia, two things must be ensured. Thus, on the one hand, the frame component must be firmly and permanently dimensionally stable, functional and load-bearing anchored in the soffit and on the other hand, the gap forming between the frame member and soffit must be reliably sealed.

A simple and widespread method for installing windows provides that between the frame member and the soffit load-bearing blocks and / or spacer blocks are arranged, which are to be secured against slipping, see. Guide to planning and execution of the installation of windows and front doors for new construction and renovation, issue March 2014 , created by RAL-Gütegemeinschaft Fenster und Haustüren eV and ift Institute for Window Technology, Rosenheim; in cooperation with, among others, BIV of the glazier trade,
Hadamar, TSD Joiner Schreiner Germany, Berlin, and Independent Advisor for Facade Technology eV (UBF), Unterschleißheim, publisher RAL Quality Association Windows and Doors eV. The guide is hereafter referred to as " Guide to planning and execution of the installation of windows and front doors for new construction and renovation, issue March 2014 By means of these load-transferring blocks and / or spacer blocks, the window can be oriented horizontally and horizontally.These load-transferring blocks and / or spacer blocks serve as load transfer between the window and the soffit.Aparticularly with different joint widths, in some cases different blocks can be combined to ensure a pressure-resistant backfilling or load transfer.

A pressure-resistant back lining in the region of the attachment points between the frame component or frame and soffit is also required for burglar-resistant assembly of components according to DIN EN 1627-1630. The DIN standard series EN 1627-1630 is a relevant test standard for doors, windows, Curtain walls, grid elements and closures. DIN EN 1627 defines various resistance classes (RC, resistance class) with regard to burglar resistance. A pressure-resistant back-lining contributes in particular to the achievement of the resistance classes RC2 or RC3, in that the pressure-resistant rear lining prevents deformation of the frame component or window frame in the direction of the soffit or structural element during burglary attempts with a lever tool.

In order to produce in particular the airtightness and the driving rain tightness, for example, a foam exhibiting jointing tape is introduced into the joint between the frame member and soffit. Such compressible joint sealing tapes are for example from the DE 19641415 C2 . DE 20009674 U1 . EP 3124712 A1 or EP 2655775 A1 known. Said joint sealing bands may comprise a plurality of foam elements, which are separated from one another, for example, by at least one membrane layer. Other jointing tapes that have no membrane layer, for example, from DE 1000946 A . DE 4020230 A1 or the DE 3407995 A1 known.

A well-known joint sealing strip, which comprises a foam, has two longitudinal sides and a in the installed state of the joint sealing strip on the joint edge, in particular a reveal, adjacent top and in the installed state of the joint sealing strip on the opposite joint edge, in particular of the frame member, adjacent bottom. Between the upper side and the lower side parallel or nearly parallel to the longitudinal sides, one or preferably a plurality of membrane layers can each extend in the longitudinal direction. As is known, the underside of such a joint sealing strip is glued to the frame component to be sealed, for example a window and door frame. After installation of the frame member, for example, in a soffit, the previously compressed joint sealing tape expands, so is elastic back, so that the top of the joint sealing tape adjacent to the soffit or is applied, and thus seals the frame member to the soffit.

When using the aforementioned blocks, the joint sealing strip is usually arranged in abutting relationship with the load-bearing blocks and / or spacer blocks. However, such abutting edges between the joint sealing strip and the load-bearing blocks and / or spacer blocks represent a leak, which are either not sufficiently protected in terms of airtightness and watertightness or must be sealed very expensive in retrospect.

Clogs also always have the disadvantage that, in particular, they can negatively influence an air-tightness layer present in the joint-sealing strip. It is independent whether the inner airtight layer is formed as a film, adhesive layer, membrane or edge coating.

In addition, such blocks may also represent an undesirable thermal bridge depending on the nature.

To solve the problem of the abutting edges, discloses the EP 3 115 539 A1 a joint sealing strip and a method for its installation in a gap between a frame member and a soffit, in which first the frame member is fixed in a desired position within the soffit and then a joint sealing strip in the gap between the frame member and soffit is arranged. In a subsequent method step, a recess is cut into the jointing sealing strip. In this recess a Verklotzungsmasse is introduced, which connects the frame member with the soffit load-bearing in the cured state.

A disadvantage of this prior art is that the introduction of the recesses in the joint sealing tape means at least one further time-consuming process step. In addition, it is possible that the recess is introduced in the wrong place or in the wrong size in the jointing tape. Any error in the introduction of the recess in the jointing tape can lead to insufficient air and water-tightness or leave depending on the formation of the necessary incision an undesirable thermal bridge arise.

Due to increasingly stringent requirements, in particular to the airtightness flaws and interruptions of the joint sealing strip and in particular a arranged in the joint sealing tape airtight plane are to be avoided.

Based on this prior art, it is an object of the present invention to overcome the disadvantages of the prior art and in particular to provide an at least partially load-bearing joint sealing tape and a method for its provision, which allows a simplified and time-saving installation of a frame member in a soffit, without damaging the joint sealing tape by cuts or cutouts or recesses.

This object is achieved by a joint sealing tape according to the preamble of claim 1 by the characterizing features of claim 1. Further developments and advantageous embodiments of the invention may be apparent from the dependent claims.

The inventive jointing compound comprising a foam is characterized in that in at least one predetermined region of the foam, a curable blocking compound is introduced, which has load-bearing properties in the cured state.

Thereby, a load-removing joint sealing tape is provided, which allows a simplified and time-saving installation of a frame member in a reveal, without the joint sealing tape is damaged by cuts or cutouts or recesses. The Verklotzungsmasse is introduced according to the invention directly into the pores of the foam. Under a reveal are understood in particular the inner surfaces of wall and ceiling openings.

By introducing the Verklotzungsmasse in the preferably at least partially open-cell foam, the pore spaces of the joint sealing tape are filled with the Verklotzungsmasse. After curing of the Verklotzungsmasse creates a pressure-resistant back-lining of a frame member that can not slip. As such, the joint sealant tape holds the load-bearing areas in place.

In addition, no cuts or cutouts or recesses must be introduced into the jointing tape, which adversely affect the tightness of the joint sealing strip. The simplified application of the joint sealing tape according to the invention also reduces the installation time and increases the safety of a correct installation.

Due to the introduced into the joint sealing tape Verklotzungsmasse other properties of the joint sealing tape, such as the heat-insulating property or an existing airtight level, not disturbed.

The jointing tape claimed according to the invention can also be provided by introducing a hardenable blocking compound into at least one predetermined area of the foam in a foam, which may already be introduced months or years ago according to the state of the art foam foam, then load-bearing in the hardened state Features.

Due to the better applicability, the curing by drying, by chemical reaction, by reaction with water or oxygen, and / or by introducing at least one further component into the at least one predetermined region of the foam is preferred.

Thus, the position of the frame member does not change in the reveal, it may be advantageous if the curing of the Verklotzungsmasse takes place quickly. In order to accelerate the hardening of the blocking mass, the areas of the joint sealing strip which comprise the hardenable blocking mass can only or in addition be irradiated with an external radiation source.
