Description

The invention relates to a profile strip for connecting a component, in particular a window or door frame, to a applied to a surface or applied plaster or tile layer.

In building construction, window and door frames, i. firmly connected to the building window and door frame, inserted and secured in corresponding wall openings of the shell. The window and door frames are usually mounted flush with the respective wall. Subsequently, a thermal skin, for example made of styrofoam or glass fibers, laid on the outside of the building wall, in such a way that the mounting joint between window or door frame and wall is covered. This prevents this assembly joint from forming a cold bridge in the connection area.

In a later construction phase, the buildings will be plastered outdoors and indoors. The plaster touches directly on window and door sills, but without due to the i.d.R. smooth surface of these components with the material of these components, in particular wood, plastic or metal to form a good connection. The same applies to tile floor coverings adjacent to window or door frames. In this case, the tiles are connected via tile adhesive and / or grout material with the window or door sills, without entering into a good connection.

Furthermore, even when drying the plaster or the tile adhesive or grout material, but also due to vibration of the window and door frames, for example, by opening and closing the window or doors, cracks and gaps between window or door frame and the plaster or tile layer form.

Moisture can penetrate into these cracks and gaps, which permanently damages the window and door sills, but also the plaster or tile layer. This is especially true in the outdoor area of buildings, but also in wet rooms in the building interior.

To address these problems, it is known to provide special protective strips or moldings that prevent direct contact between plaster or tile layer and window or door frame.

The known profile strips are formed in their core as one-piece, inherently solid and stable profiles. However, this training brings with modern buildings significant problems.

In modern buildings, the above-described thermal skin is usually stronger than 100 mm, often even thermal skins are attached with a thickness of 160 mm. This strength of the thermal skins brings with it movements, which can cause considerable damage in the connection area to window or door frames. This is especially true for the vertical connection joints, but also for horizontally extending joints.

The known moldings are usually mounted on foam-like tapes on the window or door sills. Although these adhesive tapes lead to a certain extent to a certain flexibility and mobility of the profile strip relative to the window or door frame. However, the adhesive tapes can no longer absorb the movements emanating from the modern thermal fibers of great strength, in particular in the vertical region, but also in the horizontal region. As a result, it comes to the damage already described above, in particular to cracks that are either no longer reparable or their renovation is associated with enormous costs.

The present invention is therefore based on the object of specifying a profile strip with significantly improved mobility.

This object is achieved according to the invention by a profiled strip with the features of claim 1. Advantageous embodiments and further developments are specified in the claims dependent on claim 1.

The invention provides according to claim 1, a profile strip for connection of a component, in particular a window or door stick, on an applied or applied to a surface plaster or tile layer, which is constructed at least two parts, wherein a base part (first part) for attachment of the Profile strip is determined on the component, wherein an attachment part (second part) is intended for connection of the profile strip to the plaster layer or tile layer, and wherein the base part and attachment part are movable relative to each other at least in an assembled state of the profile strip.
This profile strip has the advantage of a significantly improved recording of movements. As a result, damage to the structure, such as the damage mentioned above, completely or at least largely avoided. In particular, the profile strip also allows the recording and compensation of movements that emanate from the usual today thermal ceramics large thickness (100 mm and more).

According to a further development, it is provided that at least in an assembled state of the profile strip, the attachment part in the longitudinal direction of the profile strip and / or perpendicular to the longitudinal extent of the profile strip, in particular on the base part and / or away from the base part and / or transversely to the base part, relative to the base part is mobile.

The mobility is therefore guaranteed in all three directions. But there are also training possible, which provide only one mobility in one or two directions in space.

Preferably, the profile strip can also be designed such that at least in a mounted state of the profile strip, the attachment part relative to the base part is tiltable and / or rotatable and / or can accommodate a torsional movement.

According to one embodiment variant, the base part and / or the attachment part are designed as elongated sub-profiled strips.

Further, it is also possible that the attachment part is inserted and / or inserted into the base part. However, it can also be provided that the base part and the attachment part in a common manufacturing process are the same in the intended assignment to each other, ie. connected or inserted into each other, are produced.

In particular, the attachment part can be inserted or inserted parallel to the longitudinal extension of the profiled strip into the base part, but not be possible in another direction, in particular perpendicular to the longitudinal extent, disassembly of attachment part and base part.

According to a particularly preferred embodiment of the profile strip is provided that the base part has a recess, in particular a T-shaped recess, and the attachment part has an extension, in particular a T-shaped extension, wherein the extension is received or receivable in the recess.

In a further development of this, the dimensions of the recess and extension are matched to one another such that an intended mobility between the base part and the attachment part is given, in particular a mobility in all spatial directions and / or tiltability or

Twistability or a torsional movement of the attachment part relative to the base part.

Another particularly expedient embodiment provides that the base part and attachment in a not yet assembled state of the profile strip via at least one connecting element, in particular an inserted and / or clamped connection strip, preferably made of paper or plastic, and / or a silicone or adhesive mass, stationary connected to each other. Alternatively or additionally, the base part and the attachment part can be connected to one another in a stationary manner via at least one web, which is designed as a predetermined breaking point, preferably integrally with the base part and the attachment part. In the assembled state of the profile strip, the connecting element is removed and / or dissolved and / or broken or the web broken, to allow the mobility of the base part and attachment part.

A not yet mounted state is a profile strip, which is indeed already finished, but not yet mounted or mounted in the intended manner to a building or component. An assembled state is according to the state of a profile strip after completion of mounting or mounting on a building or component.

In a further advantageous variant of the extension of the attachment part in a partial area, in particular in a connecting web, made of an elastic material and / or soft PVC and / or a rubber-like coextrusion and / or soft foam, in particular flexible polyurethane foam. This subregion or connecting web thus forms a spring region which significantly improves the mobility between the base part and the attachment part.

The rest of the extension and / or the attachment and / or the base part consist at least predominantly of rigid PVC.

Overall, therefore, a profile strip is created with universal applications, especially a profile strip that can accommodate well large movements between the different parts of a building well, thereby preventing damage to the building.

FIG. 2

schematically in a three-dimensional representation of the profile strip of Figure 1 in an assembled state on a component, with an applied plaster layer.

In FIG 1 and FIG 2, the reference numerals for corresponding parts, components and areas are identical.

1 shows schematically a three-dimensional representation of a profiled strip 10 according to the invention, in an unassembled state. The large representation in the middle gives an overview, the upper left is the interaction of the base part 80 and attachment 81 explained with reference to an enlarged view, right above is in an enlarged view the attachment of the base member 80 to a component 11, such as a window or door frame, shown.

2 shows the profiled strip 10 according to FIG. 1 in an assembled state on a component 11, for example a window or door frame, a wooden beam or the like. The component 11 is fastened in an opening 15 of a building wall 12, wherein a gap 16 is formed between the building wall 12 and the component 11. This gap 16 is covered by a thermal skin 14 with a thickness of 100 mm or more. Instead of a building wall 12 may also be another building component, such as a ceiling or a floor.

On the thermal skin 14, a plaster layer 13 is applied in FIG 2. The plaster layer 13 is only partially shown to make visible from this layer 13 partially hidden areas of the profile strip 10.

The profiled strip 10 is formed in two parts from a base part 80 and an attachment part 81. The base part 80 has a T-shaped recess 82, the attachment part 81 a T-shaped extension 83. extension 83 and recess 84 are matched in their dimensions to one another, that the extension 83 on the one hand in the recess 84 along the longitudinal extent of the profile strip 10 is movable and on the other the attachment part 81 is held in the base part 80, in particular can not be pulled transversely to the longitudinal extent of the profile strip 10. The displaceability of the attachment part 81 in or relative to the base part 80 is comparable to the extension movement of a telescope. The profile strip 10 can therefore also be referred to as a telescopic profile strip or as a telescopic connection-expansion profile strip. The telescopic movement is the movement parallel to the longitudinal extension of the profiled strip 10.

The profile strip 10 has in the uninstalled state (also: production state) on a ridge 85 as a predetermined breaking point between base 80 and attachment 81, which connects the two parts firmly together and thus allows easy handling of the profile strip 10 in the run-up to assembly and assembly , Once the profile strip is mounted, this web 85 can be broken by slight movement of the attachment part 81 relative to the base part 80, so that then the base part 80 and the attachment part 81 are present as separate components. From this point on, the desired mobility of the two parts 80, 81 is given to each other. The unassembled state of the profiled strip 10 is shown in FIG. 1, the assembled state in FIG. 2.

For the same result, the provision of at least one connecting element between the base part 80 and attachment 81, for example, by inserting or pinching a connecting strip of paper or plastic between base 80 and attachment 81, or by locally limited introduction of a silicone or adhesive mass between the two components. In the non-assembled state, base part 80 and attachment part 81 are thereby firmly connected to one another and, in particular, do not slip against one another. By removing (for example in connection strips) and / or breaking or loosening (for example, silicone or adhesive) of these fasteners then the required and desired mobility between the base member 80 and attachment 81 is made in the assembled state. This preferred alternative, but also additive solutions to the aforementioned web 85 are not shown in the figures.

The two-part design of the profiled strip 10 by base part 80 and attachment 81 allows for a broken web 85 or removed, broken and / or dissolved connecting element movement of the attachment part 81 relative to the base part 80 in a direction parallel to the longitudinal extent of the profile strip 10. For this purpose the extension 83 moves telescopically in the recess 82, in the longitudinal direction of the profile strip 10th

On the other hand, in the illustrated embodiment, in addition to the mobility given by the foam tape 24 in a direction perpendicular to the longitudinal extension of the profile strip 10, further mobility of the attachment 81 to the base part 80 to or from the base part 80 is realized. For this purpose, the attachment 81 is not uniformly formed from a material, but is a connecting web 84 of the extension 83 (in the example, the support web of the T-bar) made of a soft PVC, in particular an elastic soft PVC, or a soft rubbery coextrudate or made of a soft foam such as a polyurethane foam as Elastoflex ^® manufactured. The other sections of the attachment part 81 and also the base part 80, however, are made of one, in particular Made of UV-resistant, rigid PVC. Such a part can be produced by injecting the soft PVC or flexible foam into the rigid PVC. Due to this design of said connecting web, a mobility of the attachment part 81 on the base part 80 to or from the base part 80 is possible away.

The profiled strip 10 shown thus enables a relative mobility of the attachment part 81 to the base part 80 in a plane perpendicular to the component 11, to which the profile strip is attached. This level also includes a parallel to the longitudinal extent of the profile strip 10. The connecting web 84 acts like a spring, it can therefore also be referred to as a spring area. As a result, the foam adhesive tape 24 is relieved of tensile forces, which could otherwise lead to damage of the tape or to a detachment from the component 11.

In addition, the choice of the dimensions of the recess 82 in the base part 80 and the extension 83 on the attachment part 81 results in a certain mobility in a direction perpendicular to the aforementioned plane. In addition, a certain tilting or rotational mobility of the attachment part 81 relative to the base part 80 can thereby be achieved. Also torsional movements can be absorbed by the mobility of base member 80 and attachment 81 against each other.

Overall, the risk of damage is at least significantly reduced, if not reduced to zero, by these possibilities for absorbing or absorbing all relevant movements in the profile strip 10.

In the figures, a trained as a thigh weatherproof attachment 27 is further recognizable on the base part 80. The weather protection attachment 27 is firmly connected to the base part 80. The weatherproofing attachment 27 covers in the installed state, the foam tape 24, via which the base member 80 is mounted on the component 11, almost completely to the outside and prevents or thereby reduces the ingress of moisture in due to the thickness the foam strip 24 formed between the component 11 and profile strip 10 gap, whereby damage to the foam tape 24 with its adhesive layers by external influences such as weather, UV radiation, etc., is largely prevented.

In FIG. 1, at the top right, it can be seen that a narrow gap remains between the weather protection attachment 27 and the component 11 in the assembled state of the profile strip 10, which has in particular the function of a diffusion gap. This gap also allows the clamping of a protective cover, such as a cover sheet and thus prevents contamination of the component during subsequent work, for example, in painting, plastering or jointing. In particular, this makes it possible at any time, i. even after completion of the plaster or tile layer, in a simple way and pollution free maintenance, for example, repair work, or perform other rework.

The illustrated profiled strip 10 is further provided with a fabric 48, which is attached to a first leg 20 (other name: tab). This first web 20 has openings 34 (also: holes), specifically triangular openings. This results in a hole pattern that creates optimal conditions for a good embedding of the profile strip 10. The plaster or putty can penetrate through the openings 34. This results in a good connection, in addition there is the connection via the fabric 48.

Overall, the profiled strip 10 shown thus represents a connection-expansion profile, in particular a telescopic connection-expansion profile. This profile strip is able to accommodate even larger strength outgoing movements of thermal skins, in particular movements in all three spatial directions, ie in the direction of an X-axis, a Y-axis and a Z-axis. Depending on the training but can also be given only one movement recording in one or two of these directions. In addition, the profile strip with appropriate training, in particular by accordingly selected dimensions and tolerances, also record a tilting movement or a rotational movement or a torsional movement.

Decisive feature for the realization of these functions is the two-part geometry of the profile strip. Along the longitudinal extension (in the figures, the vertical direction) is ensured by this bipartite mobility and thus the ability to record for corresponding movements of the thermal skin. In a plane perpendicular to the longitudinal extent (in the figures, a horizontal plane), the profiled strip shown sufficient tolerances to allow movement in the horizontal direction, without the attached to the device, such as the window or door frame, foam adhesive tape 24th claim is. Forces acting in the horizontal plane can be absorbed by the connecting web 84 made of soft PVC or a rubber-like coextrudate. The horizontal forces are thus absorbed by this soft tissue. The rest of the profile strip, however, is made of hard PVC.
