Profile strip with movable fixing

Abstract

Profile strip for creating a transition between two adjacent surfaces of a building, in particular an upper plaster layer and a component, in particular a frame part, wherein the strip is movably fixed by pins or screws after bonding.

Description

1 Description

[0001] The invention relates to a profile strip for sealing, covering, and insulating an expansion joint between a component, in particular a frame part, such as a window, and an adjacent surface of a building, in particular a plaster layer. This is especially true for surfaces that are particularly difficult to bond with the sealing tape. 2 State of the art

[0002] When sealing and insulating after installation, the transition between plaster surfaces and other components such as windows and doors represents a critical point. Firstly, the joint movements caused by temperature, wind, and driving rain loads on the elements must be accommodated. These requirements are currently met by plaster sealing strips. The plaster sealing strips are currently glued to the window frame with the sealing tape and must be held in place until the plaster is applied. However, for some time now, windows have been offered with surfaces that are, for example, dirt-repellent, and therefore do not offer good conditions for bonding. As a result, the bond loosens after a while, and the strips fall off. 3 Problem

[0003] Due to the adhesive-repellent nature of the window surface, the plaster sealing strips only have a limited adhesion to the window frame. Even brief exposure to weather conditions will cause this bond to break, and after a while, the strips will detach, causing them to fall off. Therefore, plastering must be done shortly after the battens are laid, which is often not possible. 4 Solution

[0004] The invention relates to profile strips equipped with a slotted hole or an elastic section in the profile. This allows the sealing strips to be flexibly screwed to the window frame, and the load on the adhesive bond is absorbed by the screw connection. At the same time, the connection remains elastic to meet the other sealing requirements. 6 Description of an exampleExemplary embodiment based on Figures 1, 2 and 3

[0005] The profile strip (2) is glued to the window frame (1). A screw (4) is inserted through a slotted hole (3) to secure the strip, ensuring it stays securely in place even on adhesive-resistant surfaces. The permanently elastic sealing tape (5) absorbs component movement and is not hindered in its function by the screw connections (4).

Claims
