Description

Sealing device for joint sealing between two components

The invention relates to a sealing device of a joint seal, wherein the sealing device comprises a hose-like enveloping body, which can be fixed with two opposing attachment portions to two a joint to be sealed between them forming components.

From DE 10 2004 059 522 A1, a generic sealing device has become known, which has a carrier in the form of a flexible hose, which is externally coated at least partially with adhesive and can be arranged to seal a joint between two materials and can be glued thereto. In a relative movement of these two materials, the hose can adapt flexibly to this movement. Due to its flexibility, however, the hose has no inherent stability.

From EP 1 992 776 A2, a connection profile strip has become known, which has a profile body with an outer leg and a component fastening section movably connected thereto via two connecting webs integrally formed in particular by coextrusion for fastening the strip to a frame or rail component, in particular a door or window frame or a roller blind rail, has an adhesive surface. Made of a deformable Plastic material existing connecting webs are flexible and extend from the outer leg bent to the mounting portion, so that they are deformable relative to the outer leg in a roll-like movement with a horizontal displacement of the mounting portion.

From DE 10 2007 009 945 A1 a plaster molding or profile strip for window frames of doors or is known, which has a base portion with land portions for connection to a plaster layer, a frame attachment leg for connection to the frame and a sealing lip for covering and sealing the between frame and base portion has formed joint. These mentioned components of the profile strip are formed as a structural unit. The frame attachment leg is in particular movably connected to the base section via a convexly bent connection section. A support body is formed as part of the frame attachment leg or he is z. B. a soft foam strip which is connected via adhesive layers with the frame attachment leg or the base portion. The support body holds the frame attachment legs in a defined position and thus facilitates the assembly of the profile strip. In relative movements between the profile strip and the frame in the installed state, the support body z. B. from the frame attachment leg and this allow a fitting movement. The sealing lip can adapt to the relative movement by elastic deformation and continue to seal the joint, while still covering the connection section.

A disadvantage of this plaster strip, that the frame attachment leg, the sealing lip and the support body together with the base portion form a solid unit and the sealing lip formed by the sealing device is thus specifically designed for this plaster strip and thus is not a universally applicable sealing device that also for other plaster strips would be usable.

The object of the invention is to provide a sealing device of the type mentioned above, which has good assembly properties and also with larger relative movements of the two components in the installed position an improved permanent ensures proper sealing of a joint. In this case, the sealing device should provide a position-stable mounting position at least during their assembly or processing.

The object is achieved in the above-mentioned sealing device according to the invention that the sealing device has a support means in the enveloping body, which holds the two fixing portions stabilized to each other, so that the sealing device has a supporting stability for mutual positioning of the two components during assembly, and that the support means is formed such that it permits relative movements of the two fastening sections in the installed position due to movements of the two components with deformation of the sealing device or the enveloping body which maintains a tight covering of the joint.

Advantageous embodiments of the invention are specified in the dependent claims.

A component for connecting to a sealing device according to the invention is for example a profile strip or a part of a building or another structure. A component can thus be, for example, a door frame, window frame, built-in furniture, roller shutter box, stairs, sink, shower cubicle, tile, sheet metal strip, board, beams, masonry, concrete wall, plaster, drywall or a windowsill. However, a component can also be a profile connection strip, such as, for example, the known reveal connection profiles or roof ventilation profiles or plaster finishing profiles. In an expansion joint as a joint to be sealed, for example, two profile strips can form the components and come to rest on the building parts on both sides of the expansion joint. Moldings, for example, be embedded in a building surface, as is common in plaster layers and spatula layers. Moldings can also be arranged on a building surface, as is usual in the renovation.

Joints between two components are primarily found in construction. A usual joint extends longitudinally z. B. a surface of a wall and has a certain depth perpendicular to the surface and a certain width between two components, wherein the width is constant in parallel components and may have different widths at non-parallel surfaces of the two components over their depth. Joints can be arranged, for example, vertically and horizontally on vertical building parts, whereby the removal of moisture from horizontal joints is usually more difficult than at vertical joints. All of these joints must be formed according to the known regulations and requirements mostly permanently tight.

There may be a design-related and / or weather-related relative movement between the components. Depending on various factors, these relative movements can take place in the three spatial directions and have different values. The relative movement can generate longitudinal movements and / or transverse movements and / or changes in the distance between the two components relative to one another. The sealing device solves the actual technical challenge, namely a permanent sealing of a joint with simultaneous dynamic relative movement.

The support means of the sealing device according to the invention has according to the longitudinal extent of a joint to be sealed an elongated shape z. B. in the form of a band or a strip or even a thin layer and is suitably formed from such materials that allow it to ensure the mutual positioning of the two components in the mounting position. The support means need not necessarily be tight in any design in the sense of a seal, since the enveloping body according to the invention takes over the essential seal.

A sealing device according to the invention provides both a mounting and a sealing device in spatially integrated design. The mounting device establishes a positionally stable connection of the components and serves for the initial positioning of the sealing device during assembly, while the sealing device serves for the permanent sealing of the joint. A supporting stability or stable connection for the mutual positioning of two components until the completion of the assembly or processing can be immobile or movable. For example, a support device of a sealing device according to the invention can allow a certain relative movement of the components relative to one another when force is applied during assembly. After the end of this force, the support device will preferably not return to the starting position.

Of course, a connection with stable position does not mean any connection of any two components. In construction relevant to the invention, a component may be stable, solid and heavy and the other component may be light, such as, for. B. a profile strip. A positionally stable connection holds a relatively lightweight component, such as a profile strip, on another relatively lightweight component or on a relatively heavy component. A mutual lagestabi- Ie connection of two relatively heavy components such as steel beams is not provided by the sealing device.

For the function of the sealing device, it is necessary that a certain preferred balance of forces on the components involved or their compounds is present or produced. The assembly forces are smaller than the inner holding force, adhesive force or adhesive force on the support means. These internal forces are in turn smaller than the external holding force, adhesive force or adhesive force between the support means and the respective component. These external forces are preferably in turn smaller than the tensile forces that can be absorbed by the enveloping body during relative movements. Thus, when a force is applied by a delivery and assembly force in the delivery state or in the assembled state, this supply and assembly force is transferred via a first external connection device or adhesive device and a second external connection device or adhesive device of the sealing device by the retaining force that can be absorbed by the support device, without any of the external connection devices dissolves or ruptures a material of the envelope body. As a result, the sealing device behaves technically advantageous with respect to the force flow occurring during relative movements, so that the sealing device provides the desired seal in each sealing position.

Fasteners or connections or external connections are produced, for example, by means of adhesive devices. In principle, however, other types of tight fastenings or connections such as vulcanization or welding or clamping are possible.

The essential advantage of the sealing device according to the invention is thus the flexible adaptation of the enveloping body to the respective, even large, relative movements or joint movements with a simple, cost-effective and space-saving design. The enveloping body is designed and designed according to the size of the expected relative movements. At the same time, an optionally visible portion of the sealing device in the installed state can advantageously be made narrow. During its processing, the sealing device establishes the positionally stable positioning of the two components relative to one another by the form-stable and position-stable design.

The sealing arrangement that can be produced using the sealing device consists of only one unit and is accordingly easy and inexpensive to produce. It also requires little space in the joint.

The appearance or the visual presentation of the sealing device is improved and perfect by the technical solution of the movement recording over the prior art.

Due to the two-sided, d. H. Inner and outer covering of the joint is permanently sealed. Even in case of failure of an overlap or a cover portion of the enveloping body, the seal is secured by the further covering or the further covering portion of the enveloping body.

A sealing device according to the invention has a thickness, for example, in the range of 0.5 mm to 20 mm. In the case of siding connection profiles, a For example, the thickness is about 1 mm to 5 mm, and more preferably about 2 mm to 4 mm. For expansion joint profiles for ETICS or wet plaster, a preferred thickness is for example about 2 mm to 15 mm and in particular about 4 mm to 10 mm.

A sealing device according to the invention has a width, for example in the range of about 5 mm to 50 mm. For example, in the case of suture connection profiles, a preferred width is about 5 mm to 20 mm, and more preferably about 6 mm to 12 mm. For expansion joint profiles for EIFS or wet plaster, a preferred width is for example about 8 mm to 40 mm and in particular about 10 mm to 25 mm.

The enveloping body or a sealing strip forming the enveloping body of a sealing device according to the invention has a thickness in the range of, for example, about 0.08 mm to 3 mm. For example, in terms of siding profiles, a preferred thickness is about 0.08 mm to 0.8 mm, and more preferably about 0.1 mm to 0.5 mm. For expansion joint profiles for ETICS or wet plaster, a preferred thickness is for example about 0.1 mm to 1.5 mm and in particular about 0.15 mm to 1 mm.

The dimensioning and the material properties of the sealing device are adapted accordingly to the size of the joint and to the size of the expected relative movements.

The enveloping body or a sealing band is preferably designed such that it does not tear at the described loads and thus provides or maintains the desired seal. The material of the envelope or sealing tape is selected according to the requirements of the movements and the sealing properties. The enveloping body or the sealing strip is produced, for example, from soft plastic such as, for example, soft PVC, TPE, polyethylene or similar materials. The shares of the sealing device or the profile strip or the sealing arrangement can be wholly or partially already assembled in the respective delivery condition. But they can also be wholly or partially assembled before or during assembly, for example in a manufacturing plant for moldings or components or at the construction site.

It is thus particularly preferred that, in the installed position, an external fastening or adhesive force at the respective fastening section is greater than the internal support force provided by the support device for mutual position stabilization of the two fastening sections, in particular a separation of the support device or its at least partial separation Release from the enveloping body counteracts.

If the enveloping body thus covers the supporting device both on the outside of the joint and on the inside of the joint, a double seal is ensured with greater certainty. When installing the sealing device is always a front-side coverage of the joint ensured by the enveloping body.

The envelope can z. B. be formed of at least one sealing tape. However, other designs of the enveloping body are also possible, which provide a circumferentially closed enveloping body. Several sealing bands or the like may be connected to each other at a seam or overlapping each other. As a result, in particular the production is simplified.

In a simple design, the support device is at least one adhesive layer or at least one layer-shaped adhesive device. On the other hand, the support device can be formed as a particularly deformable support body, in particular as a foam tape or foam adhesive tape. A foam tape or foam tape may also tear in its material to accommodate the movements of the components on the joint.

In a preferred embodiment, the support means may be at least partially formed integrally or integrally with the enveloping body. To the envelope or z. B. a the envelope forming sealing tape can be a support body such. B. be formed or foamed a foam tape.

Conveniently, the two opposite edge portions of the sealing tape are tightly connected to form the closed envelope body. If two sealing bands form the enveloping body, the associated edge portions of these two sealing bands can be connected to one another in an overlapping manner or in the same direction pointing outwards in the opposite direction. The connection can basically z. B. by gluing or welding.

The sealing strip between the two fastening sections is preferably folded in a U-shape and firmly and tightly connected to one another at its two edge sections in relation to this fold.

The sealing device or the enveloping body may have two substantially planar, mutually parallel and opposing mounting portions. However, non-parallel arrangements are possible when a joint to be sealed a z. B. wedge-shaped cross section.

Due to its structure, such a sealing device according to the invention can be wound up and rolled up in a roll-like or spool-like manner in the delivery state, wherein in particular a covering film with a non-adhesive or slightly adhering surface is arranged between the layers of the sealing device. This delivery method is particularly easy and inexpensive to manufacture and process.

The invention also relates to a use of a sealing device according to the invention, wherein the one to be sealed joint between the forming component is a profile strip or plaster connection strip and the other component is a frame such. B. is a window or door frame or a building surface.

In a preferred embodiment, at least one visible side portion of the sealing device or the sealing device is arranged concealed as a whole. INS In particular, the sealing device is completely or partially covered by at least one of the components. As a result, the sealing device is protected accordingly from environmental influences and in particular from the weather. The sealing device thus has a longer service life. In addition, this increases the choice of material for the enveloping body or the sealing tape or the external connection device.

In a further preferred embodiment, the sealing device or the enveloping body or the sealing tape in the direction of the support means a Oberflä- chenstruktur with elevations and depressions and / or a coating for influencing the internal support force, in particular the adhesive force of an adhesive layer or a layered adhesive device on ,

Thus, z. B. at basically the same adhesive properties or Klebekräf- an adhesive through a coating, the power transmission determined at this point and z. B. can be reduced. The sealing device may have a coating, for example of a non-woven or of fibers. Preferably, the coating then determines the internal adhesive force and thus the transferable forces. Depending on the requirement, one or more identical or different coatings may be arranged.

A similar or similar result is achieved by reducing the surface in contact with the adhesive. The surface structure may have elevations or depressions corresponding, for example, to a ribbed or knurled surface. As a result, the entire adhesive force is determined at this point with basically the same adhesive properties or adhesive forces of an adhesive and z. B. reduced. This can z. B. certain areas of an adhesive layer or a layered adhesive device with reduced adhesive force or adhesive force are formed so that the sealing device or the enveloping body or the sealing tape can be solved in this area, while at other areas with higher adhesive force or adhesive force remains in solid connection. As a result, the preferred power ratio can be improved or defined provided.

In use, an external connection device, in particular an adhesive device, for attaching the sealing device or the fastening sections to the components may be provided on the sealing device and / or on the components.

Hereinafter, a sealing device according to the invention will be explained in more detail by means of exemplary embodiments with reference to the drawing. It shows:

A component 10, for example a door or window frame (shown schematically in FIG. 1), is inserted in a wall opening of a wall 11 and connected to the wall 11. A joint 12 between the peripheral side 13 of the component 10 and the wall 11 at the soffit is by means of a Fugenfüllmaterials 14, z. B. a Füllschaumes filled out. On the exterior side 16 of the component 10 directed toward an exterior space 15, a profile connection strip 17 known per se is arranged as a connection to an outer cover layer applied to the wall 11, for example a plaster layer 18. The profile connection strip 17 has an approximately U-shaped cross section with a mounting base 19 and a front Einputzschenkel 20 and a rear Einputzschenkel 21. The profile connection strip 17 is connected to the outside 16 of the component 10 by means of a sealing device 22 according to the invention. The sealing device 22 has (see also FIG. 1 a) a hose-like enveloping body 23 extending along the profiled connecting strip 17 with a supporting body 24 contained therein. The support body 24, z. Example, a rectangular in cross-section foam tape or foam tape, by means of a Klebeeinrich- device or adhesive layer 25 and 26 fixedly attached to a respective inner surface 27 and 28 of two mounting portions 29 and 30 of the envelope 23. The fastening sections 29 and 30 are the two strip-like sections of the enveloping body 23 in the longitudinal direction of the enveloping body 23 in the region of the opposing outer planar contact or connecting surfaces 31 and 32 of the support body 24. The enveloping body 23 contains one between its two fastening sections 29 and 30 Cover section 33 or 34, wherein the front or outer cover 33 with respect to FIG. 1 covers a front, outer or visible end face 35 of the support body 24 in an approximately U-shape and the rear or inner cover section 34 a rear or inner Stirnseite 36th the support body 24 also z. B. covered in approximately U-shaped. This position information refers to a mounting position of the sealing device 22 on or in a between the profile connection strip 17 and the component 10 extending joint 37 (see Fig. 1), which is filled and sealed by the sealing device 22 sealingly attached.

Before applying the plaster layer 18 to the wall 11, the profiled connection strip 17 is fixed in a positionally stable manner by means of the sealing device 22 on the component 10 in its intended position to be maintained during plastering. To mount or fasten the profiled connection strip 17 on the component 10 (assembly position according to FIGS. 1 and 2), the sealing device 22 or the enveloping body 23 is attached to the fastening base 19 of the profiled connection strip 17 and to the outside 16 by means of two adhesive layers 38 and 39 fastened or glued to the component 10. The sealing device 22 is arranged such that the cover 33 covers the joint 37 on the visible side.

The profile connection strip 17 has, for example, a per se known tab 40 (see FIG. 2), which can be separated after plastering on a material weakening 41 of the profile connection strip 17 and on the one the component 10th or the window covering protective film 42 is bonded by means of an adhesive layer 43. The sealing device 22 keeps the profile connection strip 17 substantially stable in position in its position against a deformation force (shown schematically by arrow F ₁ ), the z. B. the weight of the profile connection strip 17 and the protective film 42 and in particular by a wind load against the protective film 42 is generated or can be.

When applying the plaster layer 18 on the wall 11 of the front Einputzschenkel 20 serves as Einputzhilfe for a cleaning tool 44 (see Fig. 2), which presses with a force F ₂ against the Einputzschenkel 20 of the profile connection strip 17. The sealing device 22 holds the profile terminal strip 17 against this applied in the usual size deformation force F ₂ in position.

After applying the plaster layer a secure sealing of the joint 37 is ensured by the enveloping body 23, which forms a joint panel, which is in particular flush with the outer surface of the front Einputzschenkels 20 of the profile connection strip 17.

The component 10 or the door or window frame and the wall 11 have a different expansion or movement behavior due to their different technical characteristics. At the joint 12 arise therefore preferably by a different expansion behavior z. B. upon exposure to heat, cold or moisture relative movements of the adjacent components. Therefore, the component 10 or the door or window frame and the wall 11 are movably connected to each other for a certain compensating movement. Due to its elastic properties, the sealing device 22 permits compensation movements between the component 10 and the profile connection strip 17 or the plaster layer 18 permanently attached to the wall.

If, as shown in FIG. 3, the component 10 moves against the profile connection strip 17 or the plaster layer 18, the joint 37 is narrowed and the sealing device 22 is compressed, wherein the elastic support body 24 is squeezed and compressed. The two cover sections 33 and 34 of the enveloping body 23 adapt to the squeezing movement and the front covering section 33 furthermore forms a joint diaphragm. The sealing effect of the enveloping body 23 or the sealing device 22 is maintained, since the two fastening sections 29 and 30 of the enveloping body 23 do not detach from or from their adhesive attachments 38 and 39.

When the component 10 moves from the initial position of FIG. 1 against the wall 11 (see FIG. 4), the sealing device 22 is stressed by shear forces, since the profile connection strip 17 retains its position on the plaster layer 18. The two outer adhesive devices 38 and 39, which hold the enveloping body 23 or its attachment portions 29 and 30 on the profile connection strip 17 and the component 10, have a greater holding or adhesive force than the inner adhesive means 25 and 26 between the enveloping body 23 and the connecting surfaces 31 and 32 of the inner support body 24, so that the adhesive bond tears at least one of the two inner adhesive devices 25 and 26 (in Fig. 4, the adhesive bonds of both adhesive devices 25 and 26 are shown in a schematic representation). As a result, the attachment portion 30 of the enveloping body 23 fixed to the component 10 shifts parallel to the attachment portion 29 attached to the profiled attachment strip 17. The folded front cover portion 33 of the enveloping body 23, for example, assumes a nearly tensioned position as shown in FIG. 4 and retains the sealing function and its Function as a joint panel. Depending on the adhesive forces, the support body 24 will thus either remain on the profile connection strip 17 or it will be displaced with the component 10. The viewing surface therefore remains uniform.

When the component 10 moves away from the wall 11 from the starting position of FIG. 1 (see FIG. 5, for example, a plastic window frame contracts), the sealing device 22 is also stressed by shear forces, since the profile connection strip 17 assumes its position maintains the plaster layer 18. The two outer adhesive devices 38 and 39, which hold the two attachment portions 29 and 30 on the profile connection strip 17 and the component 10, in turn, have a greater holding or adhesive force than the inner Adhesive means 25 and 26 between the two attachment portions 29 and 30 and the inner support body 24, so that the adhesive bond of at least one of the two inner adhesive means 25 and 26 ruptures (in Fig. 5, the lower adhesive joint 26 between the support body 24 and the on the component 10 fastened attachment portion 30 shown torn). While the support body 24 remains stationary relative to the profile connection strip 17, the fastening section 30 fastened to the component 10 displaces parallel to the fastening section 29 fastened to the profile connection strip 17, and the front cover section 33 of the enveloping body 23 assumes, for example, the position shown in FIG retains the sealing function or its function as a joint panel. The joint filling material 14 arranged in the wall joint 12 between the component 10 and the blanking or wall 11 ruptures during the movement or displacement of the component 10 shown. The viewing surface or joint panel, however, remains uniform.

When the component 10 moves away from the profiled connection strip 17 parallel to the wall 11 from the starting position of FIG. 1 (see FIG. 6, opposite movement to FIG. 3), the sealing device 22 is tensioned perpendicular to the bath fixing sections 29 and 30 claimed. In the position shown in FIG. 6, the front cover section 33 of the enveloping body 23 is almost tensioned with respect to the originally bagged position, and the reserve of movement due to bending of the non-bonded front covering section 33 of the enveloping body 23 is thus largely used up. The front cover portion 33 of the enveloping body 23 is substantially free of tensile stresses, not stretched and it forms a joint panel. The rear cover section 34 may also adapt, but this rear cover section 34 is less relevant to the sealing function and may be considered as an additional safety seal when the front cover section 33 performs the sealing function.

If the component 10 continues to move in the same direction, in the position according to FIG. 7 the non-glued front cover section 33 of the enveloping body 23 is at least somewhat tensioned over the gap 37 and its movement reserve is used up. Previously, the support body 24 has on the upper adhesive device 25 of the fastened to the profile connection strip 17 mounting portion 29 dissolved. The sealing function of the sealing device 22 for the significantly enlarged joint 37 is retained. If the enveloping body 23 is elastic and extensible at least in its front cover section 33 or the rear cover section 34 or detached in sections from the component 10, the component 10 can also move further away from the profile connection strip 17, while the front cover section 33 the joint 37 closes tight and thus continues to form a joint panel.

The enveloping body 23 of the sealing device 22 shown in FIGS. 1 to 7 is shown by way of example as a seamless tube. Preferably, however, the sealing device is made of various ribbon-like, in particular flat components, which are converted by means of a device into an enveloping body, brought together and connected to each other. As a result, a fast and inexpensive production is provided.

The sealing device 22 according to a further embodiment (see the enlarged view of FIG. 8) is constructed substantially layered and contains as a central layer the inner support body 24, for. B. in the form of a foam strip, on whose two opposing surfaces 31 and 32 each have a mounting portion 29 and 30 of the enveloping body 23 is attached by means of an adhesive device or adhesive layer 25 and 26 respectively. The two attachment portions 29 and 30 are spaced-apart strip portions of a sealing strip which forms the Hüllköper 23 and in the region of the front cover portion 33 in front of the narrow front end face 35 of the

Support body 24 is folded U-shaped. The two edge portions 45 and 46 of the sealing strip are placed in front of the rear end face 36 of the support body 24 with their inner surfaces against each other and connected to each other, for example glued, z. B. by means of an adhesive layer 47. Thus, the enveloping body 23 is closed.

The sealing device according to the embodiment of FIG. 9 differs from that of FIG. 8 in the embodiment of the enveloping body 23, which is formed by a sealing strip and on the one hand with an edge portion 48 by means of Adhesive layer 25 is connected to the upper connecting surface 31 of the support body 24, bulges with the cover 33 in front of the narrow front end side 35 of the support body 24 U-shaped, with the lower mounting portion 30 by means of the adhesive layer 26 on the lower connecting surface 32 of the support body 24 is mounted with the rear cover portion 34 on the narrow rear end face 35 of the support body 24 bulges U-shaped and placed with the other edge portion 49 on the edge portion 48 approximately in registration of the upper connection surface 31 of the support body 24 and by means of the adhesive layer 50 with This edge portion 48 of the sealing tape is glued and thus forms the upper attachment portion 29 of the enveloping body 23.
