A structural connection profile of a structural element, in particular a window, a door, a roller blind box or the like, comprises a profile body and a pre-compressed joint sealing strip fastened thereto, which is designed to expand in order to seal a gap between the profile body and the structural element. The profile further comprises a foil which holds the joint sealing tape in the pre-compressed state and is adapted to at least partially dissolve upon contact with a reactant.

Description

The present invention relates to a profile for the structural connection of a component, in particular a window, a door, a roller shutter box or the like.

In addition to a supporting or supporting function of construction profiles, profiles, in particular profiles of the type mentioned, also have a sealing function. For this purpose, a respective profile may, for example, be provided with a joint sealing strip which is arranged in the region of a joint to be sealed between the profile and the respective component when the profile is mounted on the building, for the connection of which the profile is used. The joint sealing tape, which is generally a foam tape, is preferably precompressed first and expands only in the joint in order to reliably seal it. Such pre-compressed joint sealing tape is also referred to as compriband.

In order to keep the joint sealing tape in the pre-compressed state, the joint sealing tape can be covered and rolled up, for example, on its top side and on its underside with an adhesive tape. At the construction site, a strip of the desired length is then unrolled and secured to the profile, e.g. glued. The joint sealing tape begins to expand as soon as it has been unrolled. Although the expansion of the joint sealing tape may extend to its maximum extent over a period of several minutes, hurry is therefore required in the assembly of the profile.

The joint sealing tape can also be attached to this during the production of the profile. In this case, additional means must be provided to prevent premature expansion of the joint sealing strip, as long as the profile is not yet mounted. This can be achieved, for example, by providing plastic tabs on the profile which hold the joint sealing tape in its pre-compressed form. Such provided on the profile means must then be solved or removed again in the context of assembly of the profile. For example, said plastic tabs may be configured to be folded back and / or separated.

It is an object of the invention to provide a profile for the structural connection of a component as well as a method for providing a sealed structural connection of a component, which allow a reliable sealing with simplified handling.

The object is achieved by a profile with the features of claim 1 and by a method having the features of claim 13. Corresponding advantages are also achieved by the use of claim 15. Advantageous embodiments of the invention will become apparent from the dependent claims, the present description and the figure.

The profile according to the invention is basically suitable for the structural connection of a component, in particular a window, a door, a roller shutter box or the like. The profile is in particular a soffit connection profile. Furthermore, the profile can in particular be designed to be plastered and / or used in conjunction with a thermal insulation composite system (ETICS). The profile comprises a profile body and a pre-compressed joint sealing tape fastened thereto, which is designed to expand (after the assembly of the profile) to form a joint between the profile body and the respective component, in particular a frame of the window or the door or the roller shutter box to seal. The joint sealing tape is, for example, a foam tape, preferably based on polyurethane, which is preferably impregnated. In particular, the joint sealing tape can after DIN 18542 ( DIN 18542: 2009-07 ) be formed. The joint sealing tape can also be self-adhesive on one side.

The expansion of the joint sealing strip is preferably carried out automatically as soon as the joint sealing strip is no longer held in pre-compressed state. In principle, however, it can also be provided that the expansion must first be triggered, e.g. as with a swelling tape by wetting with water. In addition, the joint-sealing tape is preferably designed to operate within a defined period of a few minutes, e.g. 10 minutes to expand to its maximum extent.

According to the invention, the profile further comprises a foil, which holds the joint sealing tape in the pre-compressed state and is adapted to at least partially dissolve upon contact with a reactant. In the film, which is preferably attached to the profile body, it is for example a plastic film. In particular, the film is substantially freely bendable so that it can be rolled, wound, folded and folded, and it may have a thickness of, for example, at most 0.5 mm, in particular at most 0.2 mm, preferably at most 0.1 mm , In order to hold the joint sealing tape in the pre-compressed state, the film may for example be tightly wrapped around the joint sealing tape or taut over the joint sealing tape and thereby secured in a suitable manner to the profile body.

A significant feature of the film is that it is specifically designed to dissolve upon contact with a defined reactant. It should be noted that this is a special property of the film, which is used specifically for the dissolution of the film. Thus, in particular, the reactant is not a reactant that is generally suitable for dissolving plastics of all kinds. Furthermore, the reaction agent preferably does not attack at least plastic, hot-dip galvanized steel, aluminum, base-coated aluminum and / or stainless steel, so that the profile body, which may in particular comprise one of these materials, is not impaired by the use of the reactant.

The benefit of the film is, in particular, that after the assembly of the profile it can be removed at least to the extent that the joint sealing tape is no longer prevented from expanding. In this way, it is first ensured by means of the dissolvable film that the joint sealing tape remains pre-compressed before and in particular during assembly. Subsequently, i. In particular, after the correct placement of the profile is already ensured, the expansion of the joint sealing strip can be triggered in a simple manner by the reaction means is brought into contact with the film. In this way, a simplified, but nevertheless reliable handling of the profile is achieved.

In principle, the reactant may simply be water, for example if the film comprises polyvinyl alcohol as the material which is suitable for producing water-soluble films. Other combinations of film and reagent, however, may be preferred, such as when the profile is to be stored outdoors and the film would be exposed to the general humidity.

Preferably, the reaction agent is a plaster, in particular a plaster after DIN EN 998 ( DIN EN 998: 2017-02 ) DIN EN 15824 ( DIN EN 15824: 2017-09 ) and or DIN 18550 ( DIN 18550: 2018-01 ), or a component of such a plaster. In this way, the reagent does not need to be provided separately. Rather, the profile may be formed such that the plaster mortar when applied to the profile preferably essentially inevitably comes into contact with the film, so that the film dissolves and can expand the joint sealing tape. A separate step for the application of the reagent for dissolving the film can thus be dispensed with.

According to an advantageous embodiment, at least a part of the joint sealing strip is glued to the profile body. The joint sealing strip can be glued, for example, on a leg of the profile body. Preferably, the joint sealing tape extends parallel to the longitudinal extent of the profile body, in particular over its entire length. If the joint sealing tape is not at least one side self-adhesive, for example, a double-sided adhesive tape can be used for sticking.

According to a further advantageous embodiment, the film is attached to at least one end portion of the profile body, in particular on a leg of the profile body. The end section of the film is formed, for example, by a strip of the film which extends along an edge of the film and is fastened aligned parallel to the longitudinal extent of the profile body on the profile body. The attachment can be done for example by sticking and / or sewing.

It is preferred that the film is fastened with a first end portion on a first leg of the profile body and with a first end portion opposite the second end portion at an angle to the first leg aligned second leg of the profile body. The first and the second end portion may be arranged in particular at opposite edges of the film. For releasing the joint sealing tape held by the film in the pre-compressed state, only such a part of the film then needs to be dissolved that thereby the first and the second end portions are separated from each other.

The legs of the profile body can be aligned, for example, at least approximately 90 ° to each other angled, so that the profile body in cross section has an L-shape. In principle, however, other angles are possible. However, the profile body is not limited to only two legs, but also other legs or other additional structures, e.g. Stiffening ribs or sealing lips, have. The attachment of the end portions of the film is preferably on the outer sides of the legs, which are connected by an angle of more than 180 °. By attaching the opposite end portions of the film to two legs of the profile body, a circumferentially closed structure can be formed, which encloses the joint sealing tape, preferably along the entire longitudinal extension of the profile body, and thereby holds in its pre-compressed state.

The first end portion of the film is preferably on the first leg of the profile body, in particular by means of a double-sided Adhesive tape, glued on. The joint sealing tape in turn can advantageously be glued to the first end portion of the film, preferably also by means of a double-sided adhesive tape. Thus, for example, first the first end portion of the film can be attached to the first leg of the profile body and then the joint sealing tape are glued to the first end portion. Subsequently, the film is tightly wrapped around the joint sealing tape and secured to the second end portion on the second leg of the profile body to hold the joint sealing tape in its pre-compressed state.

On the second leg of the profile body, the second end portion of the film may in particular be sewn. If the profile has a reinforcing fabric, it is preferably provided that the second end portion of the film and the reinforcing fabric are sewn to the profile body by means of a common seam. This is particularly possible because the joint sealing tape can be released by dissolving the film for expansion and therefore the seam need not be solved.

According to an advantageous embodiment, the film encloses the joint sealing tape at least substantially completely in its entirety, at least as long as it has not (partially) dissolved. at least once in the circumferential direction about the longitudinal extent of the joint sealing strip completely around the joint sealing tape around. However, the film does not have to be continuously closed, but may basically have openings, e.g. be formed mesh or lattice-like. By fully enclosing the joint sealing tape is held particularly reliable in its pre-compressed state.

According to a further advantageous embodiment, the profile body is designed such that the reagent can be applied to the film when the profile is mounted. In particular, when the profile is mounted, the pre-compressed joint sealing strip is arranged in the region of the joint between the profile body and the respective component, which is to be sealed by the joint sealing strip. Since the joint sealing tape can be difficult to access, the profile body is preferably designed such that nevertheless reaction agent can preferably be applied directly to the film or, if this is not possible, at least to the film can be conducted, for example by appropriate structures in the profile body. The application of the reaction agent can be carried out in particular by spraying it against the film, heating it up, applying it and / or filling it, in which case it may, if necessary, continue to propagate in the direction of the film or over the film.

In particular, in this context, an embodiment is further advantageous in which at least one leg of the profile body has passages which are spanned by the film and through which the reagent can be applied to the film. The leg is preferably the mentioned second leg of the profile body. Such passages in at least one leg of the profile body may allow the required accessibility of the film for the reagent and at the same time be advantageous for a plastering of the profile to the structure.

The method according to the invention for providing a sealed structural connection of a component, in particular a window, a door, a roller shutter box or the like, comprises the following steps: first, the mounting of a profile has a structural connection, which has a profile body, a pre-compressed joint sealing strip fastened thereto and a foil holding the joint sealing tape in the pre-compressed state and configured to at least partially dissolve upon contact with a reactant, the profile in particular being able to be formed in accordance with one of the embodiments described above; and secondly, applying the reaction agent to the film to dissolve at least a portion of the film and thereby release the joint sealing tape for expansion, so that through the expanded joint sealing tape a joint between the profile body and the respective component, in particular a frame of the window or the door or the shutter box is sealed.

Compared to a method in which the joint sealing tape is present separately from the profile body and is held by a packaging or a kind of storage in pre-compressed state, and then released by releasing this holding for expansion and fixed to the profile body and the profile only after can be mounted, the handling of the profile is considerably simplified in the said method. Because the profile can be mounted directly and without time pressure, and the joint sealing strip is advantageously only then, if it is already in the joint to be sealed, released for expansion by simply applying the reagent. This step may also coincide with an optionally anyway provided step of plastering, when the reagent is formed by the plaster or a part thereof.

According to an advantageous embodiment of the method, the application of the reaction agent to the film comprises that the reagent, in particular through passages in a leg of the profile body, sprayed against the film, fired, wound up and / or filled. Preferably, the reagent thereby passes directly to the film. But it can also be provided that the reagent is passed only as a result of this procedure to the film or at least to remote parts of the film.

Basically, there is an improved handling of a profile for the structural connection of a component, in particular a window, a door, a roller shutter box or the like, characterized in that in contact with a reactant at least partially self-dissolving film for holding a mounted on the profile joint sealing tape in a precompressed Condition is used.

The invention will be further explained by way of example only with reference to the figure.

• The 1 shows an embodiment of a profile according to the invention in a schematic cross-sectional view.

At the in 1 shown profile 11 it is a soffit connection profile, which is used for the structural connection of a window. The profile 11 has a profile body 13 with a first leg 15 and at a right angle to the first leg 15 aligned second leg 17 on, longer than the first leg 15 is. In the middle and at the free end of the first thigh 15 extend parallel to the second leg 17 and in the same direction as this short extension 19 , The profile body 13 has the illustrated cross section at least substantially over its entire longitudinal extent.

The profile 11 is adapted to be placed in a corner between a window frame and the soffit of the window, wherein the first leg 15 with its outside against the window frame and the second leg 17 is applied with its outside against the soffit. On the inside of the second leg 17 can the profile against the soffit fitting 11 , in particular up to one through the first leg 15 defined height, plastered. To support the connection of the profile 11 the plaster is on the second leg 17 in its extension a reinforcing fabric 21 provided on the inside of the second leg 17 of the profile body 13 with a seam 23 is sewn and formed like a net, so that it can be penetrated by plaster plastering. In addition, the second leg 17 crossings 25 on, in regular arrangement over the second leg 17 are distributed and through which basically also plaster can reach the soffit.

To prevent moisture in the gap between the profile 11 , in particular the first leg 15 of the profile body 13 , and the window frame, is at the free end of the first leg 15 a soft lip 27 provided with the mounted profile 11 rests against the window frame. For a more reliable sealing of the gap between the first leg 15 and the window frame is also a pre-compressed joint sealing tape 29 on the outside of the first leg 13 attached. In its precompressed state, the joint sealing tape becomes 29 through a foil 31 held the joint sealing tape 29 in the circumferential direction around the longitudinal extent substantially completely tightly encloses.

Here is a first end section 33 the foil 31 by means of a double-sided adhesive tape 35 on the first thigh 15 of the profile body 13 glued on and the joint sealing tape 29 with its underside again by means of a double-sided adhesive tape 37 on the first end section 33 glued on, leaving the film 31 once around the joint sealing tape 29 wound and with a the first end portion 33 opposite second end portion 39 on the second leg 17 of the profile body 13 can be sewn on. For sewing the second end section 39 the foil 31 to the second leg 17 of the profile body 13 is doing the same seam 23 as for sewing the reinforcing fabric 21 used, so that sewing the film 31 and sewing the reinforcing fabric 21 in the production of the profile 11 can be done as a single step.

After the profile 11 mounted, this must be from the foil 31 wrapped joint sealing tape 29 be solved so that it, in particular perpendicular to the first leg 15 of the profile body 13 , expand and in this way the gap between the profile 11 and the window frame can seal. The release takes place in that the film 31 at least partially dissolves due to contact with a particular reagent. In principle, it can be provided that the film 31 completely dissolves. But it may be enough if the film 31 at least along a region that dissolves over the entire longitudinal extent of the profile 11 extends.

For example, the film may 31 in an area on the outside of the second leg 17 of the profile body 13 between the seam 23 and the corner between the first leg 15 and the second leg 17 of the profile body 13 dissolve. For this purpose, the reagent can easily pass through the passages 25 through the film 31 be applied. The passages 25 are doing so over the second leg 17 of the profile body 13 that distributes the reactant, after passing the passages 25 still along the surface of the outside of the second leg 17 can spread, a total of a contiguous area of the film 31 achieved, so that the connection between the first end section 33 and the second end portion 39 the foil 31 is separated and the joint sealing tape 29 then expand. If the slide 31 reacting with a reactant that is part of a plaster or can be added to a plaster of mortar as a further component, the application of the reagent on the film 31 by plastering the second leg 17 of the profile body 13 done so that even during assembly a step can be saved.

The 1 shows a concrete embodiment, a soffit connection profile for the structural connection of a window. However, the underlying concept of a held by a dissolvable film in precompressed state jointing tape is basically equally applicable to other profiles, especially on plaster profiles and profiles for thermal insulation systems, especially when doing a seal.
