Description

[0001] The invention relates to a connection profile for components adjacent to plaster, in particular for window frames, door frames or roller shutter tracks, with a base profile on which a protective tab is removably arranged, wherein the base profile has a receiving space in which at least one sealing element, for example a joint sealing tape, is completely received at least during assembly, and wherein a releasable closing element is provided which interacts with the base profile to close the receiving space of the base profile at least during assembly.

[0002] Connection profiles with integrated joint sealing tape are particularly needed in external thermal insulation composite systems (ETICS) to create an airtight and watertight connection joint. EP 2 292 886 B1 describes a sealing strip of the type mentioned above, which has an expansion strip for sealing against a building component, wherein the expansion strip is held in a compressed state, at least temporarily, by a retaining element.

[0003] The connection profiles described in the prior art have a closing element for the receiving area, which is removed as needed to expose the joint sealing tape. Furthermore, tear-off tabs or protective tabs are provided for mounting the connection profiles, to which, for example, protective films can be attached to protect certain building components such as windows or doors during installation. These tear-off tabs are also removed after installation.

[0004] The object of the invention is to further develop the known connection profiles in such a way that they have a compact design and are easy to handle during assembly.

[0005] This problem is solved according to the invention by arranging at least one functional element on the surface of the closure part facing away from the receiving space.

[0006] The purpose of functional elements is to improve the function of the connection profile and / or to facilitate its installation. These functional elements serve, for example, to fix and / or fasten the connection profile to a building component, to protect building components, and / or to ensure a safe distance from building components. Often, these functional elements are only needed during installation and are subsequently removed. To enable simple and quick removal of these functional elements, the invention provides that at least one functional element is arranged on the surface of the closure part facing away from the receiving area.

[0007] This means that, if necessary, removing the closure part to expose the sealant, for example the joint sealing tape, simultaneously removes at least one functional element that is no longer needed.

[0008] In one embodiment of the invention, at least one functional element acts as a fastening element, at least during assembly, and is, for example, an adhesive tape. The temporary fixing of the connecting profile to the substrate, for example, a window frame, significantly simplifies the assembly of the end profile according to the invention. After completion of the assembly, the fastening element is removed in one step together with the sealing element to release the sealing material.

[0009] Alternatively or additionally, at least one functional element can act as a spacer, at least during installation. For this purpose, it is preferably made of an elastic material, for example, a foam strip. During installation, this spacer ensures that the connection profile according to the invention is installed at the correct distance from the component, for example, a door or window frame. This distance is necessary so that the sealant, in particular joint sealing tape, can expand out of the receiving space after the connection profile has been installed and the sealing element removed, in order to achieve a proper seal between the component and the building wall. Such spacers also serve to prevent the plaster from cracking and to ensure overall stability during installation.

[0010] In a particularly preferred embodiment of the invention, the cross-sectional width of the at least one functional element is equal to or less than the cross-sectional width of the receiving space. Thus, the arrangement of the at least one functional element according to the invention below the receiving space of the base profile allows for a particularly slim design of the connection profile with a significantly reduced profile width compared to known connection profiles of the prior art, in which the at least one functional element is usually arranged essentially next to the receiving space for the sealing material or in the plane of the base profile. The connection profile according to the invention preferably has a profile width of less than 15 mm, whereas connection profiles according to the prior art typically have a profile width between 20 mm and 35 mm.This minimal profile width of the connection profile according to the invention makes it particularly possible to subsequently mount the connection profile according to the invention on a building component without having to, for example, at least partially remove reveal insulation.

[0011] In a particularly preferred embodiment of the invention, the closure part and the protective flap form a one-piece closure element, for example made of rigid PVC, which can be easily removed after mounting the connecting profile, for example by pulling it out.

[0012] It is particularly preferred that the at least one functional element and the locking element can be removed together in one step after the connecting profile has been mounted. The locking element thus comprises, on the one hand, a locking part that serves to close the receiving space, and on the other hand, a protective tab that is inserted during assembly in a manner known per se. After assembly, the protective tab acts as a gripping element to pull out the locking element. Due to its one-piece construction, the entire locking element is removed from the connecting profile according to the invention by pulling on the protective tab. In this way, the receiving space in the base profile is released, and the sealing element can expand towards the component.

[0013] In a preferred embodiment of the invention, a distal end of the closure element interacts with a retaining rib of the base profile to close the receiving space. In a particularly preferred embodiment, the retaining rib of the base profile has a receptacle into which the distal end of the closure element engages. This creates a snap-lock-like connection that ensures a stable closure of the receiving space and can be easily and securely released, if necessary, by pulling the closure element out of the connecting profile. Of course, other connections between the closure element and the retaining rib of the base profile are also possible, for example, in the form of a tongue-and-groove joint or the like.

[0014] A significant advantage of the locking element described above, which combines the locking part and protective flap in a single piece, is that after the connection profile according to the invention has been installed, the locking element can be pulled out essentially along a plane parallel to the installation plane. This avoids damage to the building wall surrounding the component, particularly the plaster, in contrast to known prior art solutions where the protective flap must be bent and / or torn off at an angle or perpendicular to the installation plane to remove it.

[0015] A key aspect of the invention is that below the receiving space of the base profile, on the surface of the closure part facing away from the receiving space, at least one functional element, but usually more than one functional element, is arranged, which are typically removed together with the closure part in one step after the assembly of the connection profile according to the invention.

[0016] The invention will now be explained in more detail using a non-restrictive embodiment with accompanying figures. These figures show... Fig. 1 a perspective view of the connection profile according to the invention; Fig. 2 the connection profile according to the invention made of Fig. 1 in a sectional view with locking element; Fig. 3A the locking element in a sectional view; Fig. 3B the connection profile according to the invention in a sectional view after removal of the locking element; and Fig. 4 the connection profile according to the invention in a sectional view after removal of the locking element in the assembled state.

[0017] The connection profile 100 according to the invention Fig. 1 has a base profile 110 to which a reinforcing fabric 101 is attached in a manner known per se. The base profile 110 has a receiving space 120 in which a sealant, for example an expanding, elastic joint sealing tape 130, is arranged. The receiving space 120 is formed by a retaining web 111 and a cover strip 112 of the base profile 110 as a recess that is essentially U-shaped in cross-section. The receiving space 120 is closed before and during assembly by means of a closing element 140 such that the joint sealing tape 130 is completely contained within the receiving space 120. Fig. 2).

[0018] This closure element 140 has a closure part 141 that closes the receiving space 120, the closure part 141 interacting with the retaining web 111 of the base profile 110. The surface of the closure part 141 facing the receiving space 120 lies essentially in a closure plane V. In this embodiment of the invention, the closure part 141 engages with a distal end 141A in a receptacle 111A of the retaining web 111, which has a substantially hook-like cross-section, thus closing the receiving space 120.

[0019] On a surface of the closure part 141 of the closure element 140 facing away from the joint sealing tape 130 or the receiving space 120, a functional element, for example a foam tape 150, is arranged, which is fixed in its position relative to the closure element 140 by a protective film 151. On the surface of the protective film 151 facing away from the foam tape 150, a further functional element, in this case a first adhesive, for example an adhesive strip 171, is provided, with the aid of which the connection profile 100 according to the invention can be fixed in its position during assembly.

[0020] Furthermore, the closure element 140 has a protective flap 142 which is additionally connected to the cover strip 112 of the base profile 110 via a material connection 160. A further adhesive, for example a second adhesive strip 172, is provided on a first surface 142A of the protective flap 142. During assembly, a protective film, for example, can be attached to this second adhesive strip 172 to cover a building component, such as a window or door, in order to protect the building component, particularly during plastering.

[0021] The protective film 151 of the foam tape 150 is permanently attached to the second surface 142B of the protective flap 142, opposite the first surface 142A ( Fig. 3A).

[0022] After assembly, the locking element 140 is pulled out of the connection profile 100 according to the invention along the locking plane V using the protective tab 142, so that the locking part 141 releases the receiving space 120 of the base profile 110 and the joint sealing tape 130 can expand ( Fig. 3B). Here, the material connection 160 to the cover strip 112 is also released as soon as the locking element 140 is removed from the connection profile 100 according to the invention along the locking plane V, which in the installed position is essentially parallel to the installation plane E ( Fig. 4) is pulled out. At the same time, the foam element 150 with its protective film 151 is also removed from the connecting profile 100 and remains attached to the locking element 140.

[0023] In the Fig.Figure 4 shows the connection profile 100 according to the invention in its installed position after assembly. The connection profile 100 is attached to a building wall 200 by means of plaster 210. A finishing plaster 220 is applied to the surface of the plaster 210 facing away from the building wall 200.

[0024] The joint sealing tape 130, which protrudes from the recording space, seals a sealing joint 230 between the building wall and the component, here a window frame 300, to the outside.
