Description

[0001] The invention relates to a sealing device for an edge joint between a panel of a drywall and an adjacent floor, wall, or ceiling. Furthermore, the invention relates to a drywall with at least one panel and at least one such sealing device.

[0002] Edge joints, especially floor joints, are designed to ensure sound decoupling of the drywall from adjacent walls, ceilings or floors, especially floors.

[0003] The wall surfaces of drywall walls are formed by sheathing elements such as plasterboard, which often require protection from moisture. The edge joints therefore also form a barrier that protects the sheathing elements from rising moisture, for example, in the event of a pipe burst.

[0004] The edge joints are usually filled with a sealant to provide sound and fire protection and to seal the joint against air and odors.

[0005] Sealants have the disadvantage that their application is time-consuming and not very ergonomic. Furthermore, sealants can generally only be used reliably at temperatures of at least 5 °C, and the substrate must be dry. Inspection is also challenging, as, for example, the installation depth cannot be verified non-destructively.

[0006] US 2017 / 328057 A1 discloses a generic sealing device.

[0007] The object of the invention is to provide a sealing device for an edge joint of a drywall, which ensures simple installation of the sealing device and effective sealing of the edge joint.

[0008] To solve this problem, a sealing device for an edge joint between a panel of a drywall and an adjacent floor, wall, or ceiling is provided, comprising a one-piece base body. The base body has a support section that forms a support for the peripheral side of the panel, a contact section extending from the support section and projecting in a first direction at an angle relative to the support section for contacting an edge of an end face of the panel, and a sealing section extending from the support section and extending away from the support section. The sealing section has two spaced-apart webs that bridge the edge joint.

[0009] It was recognized that such a sealing device can be installed with minimal effort. The support section and the contact section ensure that the sealing device is precisely aligned with the paneling, while the webs of the sealing section seal and close an edge joint with a specified width. This effectively protects the paneling from moisture from an adjacent floor, wall, or ceiling. Furthermore, the webs of the sealing section form two functionally connected sealing layers in series along the joint depth, thus providing a particularly effective seal.

[0010] In one embodiment, the contact section and one of the webs lie in one plane, whereby the sealing device can be designed to be particularly compact and stable.

[0011] In a further embodiment, a web extends from each of the opposite ends of the support section, viewed in cross-section. Thus, the webs extend away from the support section at the opposite ends, so that the distance between the webs is particularly wide. This has the advantage that the webs can support the paneling part particularly well. This is particularly advantageous in a floor joint, where the paneling part rests on the support section and can be supported on the floor via the webs, for example, for assembly.

[0012] It can be provided that the two webs of the sealing section run parallel when viewed in cross-section. This allows the sealing section to be particularly stable and / or to have consistent sealing properties across the joint width over which the webs extend.

[0013] According to one embodiment, the sealing section has a seal that is present between the webs. In particular, in the unloaded state, the seal protrudes from a space formed between the webs of the sealing section. The seal, for example, merges integrally into the webs or is made of a different material than the webs. With this design, the sealing device has a third sealing level arranged between the two webs. Thus, the sealing effect of the sealing device can be improved without increasing the installation space required for the sealing device. Furthermore, the sealing section has an intumescent seal that is present between the webs. This provides particularly protected positioning of the intumescent seal, thus preventing damage to the intumescent seal, especially in logistics or during assembly.In this way, a particularly reliable sealing effect can be ensured, in particular over the entire length of the sealing device and thus over the entire length of the edge joint.

[0014] According to a further embodiment, at least one of the webs branches off in a V-shaped cross-section near a free end to form a sealing lip. The sealing lip provides an additional sealing level. Furthermore, the sealing lip can be designed to have a particularly high sealing effect, particularly due to its shape and / or material.

[0015] The contact section can form a U-shaped clamp section at its free end, viewed in cross-section, which is open toward the webs. The clamp section is designed to allow the sealing device to be attached to a mounting rail provided by the customer. This allows the sealing device to be installed quickly, reliably, and in a defined manner without the need for additional fastening devices.

[0016] Additionally or alternatively, the sealing device, in particular the base body, can be an H-profile, in which the support section forms the central web, two webs form the sealing section, and two opposing webs form the contact section. The paneling part can be accommodated between the webs of the contact section. This has the advantage that the sealing device is reliably aligned in a defined manner with the paneling part.

[0017] In this case, it can be provided that at least one of the webs of the contact section extends outward toward its free end to form an insertion bevel for the paneling part, and / or that the two webs of the contact section extend toward each other and away from each other in sections in the region of their free end to form a clamping zone for the paneling part. In this way, the sealing device can be pushed onto and / or fastened to the paneling part with little effort, in particular without tools and without fasteners.

[0018] In an alternative embodiment, the sealing device, in particular the base body, is an H-profile, in which the support section forms the central web, at least two webs form the sealing section, and an oppositely extending web forms the contact section. Compared to an H-profile, one side of the profile in this design has no web and is thus open. This has the advantage that the paneling part can be placed or pushed onto the support section via the open side, allowing for more flexible installation, especially in confined spaces.

[0019] The sealing device is preferably an extrusion profile, which allows the sealing device to be manufactured with little effort and in any length.

[0020] In an alternative embodiment, at least part of the sealing device can be an extrusion profile, in particular the base body.

[0021] According to the invention, to achieve the above-mentioned object, a drywall wall with at least one paneling part and at least one sealing device according to the invention with the aforementioned advantages is also provided. The paneling part rests with its peripheral side on the support section, and the sealing section rests on the adjacent floor, wall, or ceiling. In this way, the edge joint formed between the at least one paneling part and the adjacent floor, wall, or ceiling can be sealed reliably and with minimal effort by the sealing device.

[0022] In one embodiment, the drywall has a sealing device in which the contact section forms a U-shaped clamp section at its free end, viewed in cross section, which is open in the direction of the webs, as well as a support rail fastened on site, which projects from the floor, the wall or the ceiling and which is inserted into the clamp section.

[0023] Additionally or alternatively, the sealing device, in particular the base body, can be an H-profile and the planking part can be inserted between two webs of the contact section.

[0024] Further advantages and features are evident from the following description and the attached drawings, whereby only Figures 4 and 5 show a sealing device according to the invention: Figure 1 in a schematic sectional view of a drywall with a sealing device, Figure 2in a schematic sectional view of the sealing device Figure 1 , Figures 3 and 4 each in a schematic sectional view a drywall with a sealing device according to a further embodiment, and Figures 5 to 8 each in a schematic sectional view of further embodiments of sealing devices according to further embodiments including drywalls.

[0025] In Figure 1 a drywall 10 with a planking part 12 (gypsum wall) and a holding rail 14, which is part of a stud construction of the drywall 10, is shown in cross section.

[0026] In the present case, the support rail 14 is a floor profile that is firmly anchored to the floor 8, for example by means of dowels.

[0027] The planking part 12 is attached to the stud construction at a distance from the floor 8, whereby an edge joint 16 in the form of a floor joint is formed between a peripheral side 18 of the planking part 12 and the floor 8.

[0028] In order to seal the edge joint 16, the drywall 10 further comprises a sealing device 20, the structure of which is described below with reference to the Figure 2 The sealing device 20 is also suitable for sealing the edge joint 16 between the drywall 10 and the ceiling and / or wall.

[0029] The sealing device 20 has a one-piece base body 22 with a flat support section 24, a sealing section 26 comprising a first web 28 and a second web 30 extending at opposite ends of the support section 24 at right angles from the support section 24, and a contact section 32 comprising a third web 34 extending at right angles from the support section 24 opposite the first web 28. The first web 28 and the third web 34 are arranged at the same end of the support section 24 and thus lie in one plane.

[0030] As a result, the base body 22 has an H-shaped profile that runs over the entire length of the straightening device 20.

[0031] The support section 24 forms a support 36 on its side opposite the sealing section 26, against which the planking part 12 rests with its peripheral side 18 (see Figure 1 ).

[0032] The edge 38 of the inner end face 40 of the planking part 12 adjacent to the peripheral side 18 rests on the third web 34.

[0033] At the end of the third web 34 opposite the support section 24, the contact section 32 has a clamp section 42 by means of which the sealing device 20 is fastened to a side cheek 44 of the holding rail 14.

[0034] The clamp section 42 has a U-shaped cross-section which is open at the bottom, whereby the sealing device 20 can be plugged onto the side cheek 44 counter to the vertical direction V.

[0035] In this case, the clamp section 42 is designed to be particularly long in the vertical direction V, so that the sealing device 20 can be plugged onto holding rails 14 with side cheeks 44 of different heights and at the same time rests with its sealing section 26 on the floor 8 in order to reliably seal the edge joint 16.

[0036] The clamp section 42 further has an insertion bevel 46 to simplify the attachment of the sealing device 20 to the holding rail 14.

[0037] The first and second webs 28, 30 extend in the installed state (see Figure 1 ) from the support section 24 against the vertical direction V to the base 8 and thus form two sealing planes which are spaced apart from each other in the horizontal direction H.

[0038] Between the two webs 28, 30 of the sealing section 26 there is thus a space 48 which is closed on one side by the support section 24.

[0039] The sealing section 26 has a seal 50 with an arcuate profile, which extends between the opposite sides of the two webs 28, 30 of the sealing section 26 and in the unloaded state (see Figure 2 ) protrudes from the space 48 beyond the webs 28, 30. When installed (see Figure 1), the seal 50 lies elastically and under pre-tension flat against the base 8, whereby a particularly high sealing effect is achieved.

[0040] The seal 50 is formed in one piece with the webs 28, 30 of the sealing section 26 and thus consists of the same material as these.

[0041] In an alternative embodiment, the seal 50 may be formed from a different material than the webs 28, 30 of the sealing section 26, in particular a material with a lower strength.

[0042] The sealing section 26 further comprises, as a fire protection function, an intumescent strip 52 which is attached to the side of the second web 30 opposite the space 48.

[0043] The sealing device 20 is an extruded profile manufactured by 2-component extrusion.

[0044] The base body 22 consists of a plastic, for example EPDM, PVC, foam rubber, thermoplastic elastomer or silicone.

[0045] In an alternative embodiment, the base body 22 may have a composite structure, for example a metal core with a plastic sheath.

[0046] In principle, the sealing device 20 can be made of any material and in any manner. Preferably, however, at least the base body 22 is an extruded profile.

[0047] In order to reliably seal the edge joint 16 with the sealing device 20, the sealing device 20 with the clamp section 42 is attached to the holding rail 14 during the assembly of the drywall 10, which is preferably anchored to the floor 8 before this step.

[0048] The sealing device 20 is designed so that it does not interfere with the installation of vertical studs of the stud construction of the drywall 10. This means that the vertical studs can be installed after the sealing device 20 has been attached to the support rail 14.

[0049] Now the planking part 12 is placed with its peripheral side 18 on the support section 24 so that the edge 38 of the end face 40 rests against the contact section 32 and the sealing section 26 is pressed against the floor 8, and then fastened to the stud construction of the drywall 10.

[0050] By placing the planking part 12 on the sealing device 20 during assembly, it is ensured that the edge joint 16 has a defined width, while the weight of the planking part 12 ensures that the sealing section 26 lies tightly against the floor 8.

[0051] In principle, the sealing device 20 can be used to seal any edge joint 16 formed between a peripheral side 18 of the paneling part 12 and an adjacent floor, an adjacent wall or ceiling.

[0052] Based on the Figure 3 A sealing device according to a further embodiment will now be described. The same reference numerals are used for the components known from the above embodiment, and reference is made to the previous explanations.

[0053] In contrast to the sealing device 20, which is Figures 1 and 2 As shown, the base body 22 has a sealing rib 54 projecting laterally from the contact section 54, which is designed to seal the gap between the contact section 32 and the edge 38 of the inner end face 40 of the paneling part 12.

[0054] Furthermore, instead of the seal 50, the sealing section 26 has a first sealing lip 56 and a second sealing lip 58 which lie tightly against the base 8.

[0055] The bottom ends of the first and second webs 28, 30 in this embodiment each have a V-shaped cross-section which spreads out towards the bottom 8.

[0056] The first sealing lip 56 is formed by the leg of the "V" of the first web 28 that faces the space 48, while the second sealing lip 58 is formed by the leg of the "V" of the second web 30 that faces away from the space 48.

[0057] Furthermore, in the illustrated embodiment, no intumescent strip 52 is provided, but this may also be different.

[0058] Based on the Figure 4A sealing device according to a further embodiment will now be described. The same reference numerals are used for the components known from the above embodiments, and reference is made to the previous explanations.

[0059] In contrast to Figure 3 In the embodiment shown, the sealing device 20 has, instead of the first sealing lip 56, an intumescent strip 52 which is attached to the first web 28 in a protected manner in the space 48.

[0060] Based on the Figure 5 A sealing device according to a further embodiment will now be described. The same reference numerals are used for the components known from the above embodiments, and reference is made to the previous explanations.

[0061] In this embodiment, the sealing device 20 has, in addition to a sealing lip 56 on the first web 28, an intumescent strip 52, which is attached to the second web 30 in the space 48. This design protects both the sealing lip 56 and the intumescent strip 52.

[0062] The sealing lip 56 is designed to be longer than the webs 28, 30.

[0063] Furthermore, instead of the clamp section 42, the sealing device 20 has an adhesive strip 60 which is attached to the side of the third web 34 facing the carrier section 24.

[0064] During the installation of the drywall 10, the sealing device 20 is attached to the sheathing part 12 and not to the support rail 14. The sealing device 20 is glued to the edge 38 of the inner end face 40 of the sheathing part 12 using the adhesive strip 60 so that the peripheral side 18 rests against the support section 24. The sheathing part 12, together with the sealing device 20, is then attached to the stud construction of the drywall 10.

[0065] In order to reliably attach the sealing device 20 to the paneling part 12, the contact section 32 can additionally be fastened to the paneling part 12 by means of clamps.

[0066] Of course, according to a further embodiment, the sealing device 20 can be provided to be attached to the paneling part 12 by means of clamps. In this case, the adhesive strip 60 can be omitted.

[0067] Furthermore, in all embodiments, the adhesive strip 60 can be provided in addition to a fastening device, in particular a clamp section 42. In this case, the adhesive strip 60 can be used additionally or alternatively for fastening, thereby allowing the sealing device 20 to be used more flexibly.

[0068] In addition, the adhesive strip 60 can be provided as a sealing element to seal the gap between the contact section 32 and the edge 38 of the inner end face 40 of the paneling part 12.

[0069] Based on the Figure 6 A sealing device according to a further embodiment will now be described. The same reference numerals are used for the components known from the above embodiments, and reference is made to the previous explanations.

[0070] In contrast to the previous embodiments, the sealing device 20 has a sealing section 26 with a further web 62, ie the sealing section comprises three webs 28, 30, 62.

[0071] The further web 62 extends parallel and equidistant to the webs 28, 30 away from the support section 24 and in this way divides the space 48.

[0072] The three webs 28, 30, 62 of the sealing section 26 have the same height in the vertical direction V and form three sealing levels in the horizontal direction H.

[0073] Furthermore, the webs 28, 30, 62 of the sealing section 26 and the support section 24 have a wall thickness that is twice as large as the wall thickness of the contact section 32 or the third web 34.

[0074] In principle, the webs 28, 30, 62 of the sealing section 26 and the support section 24 can have any desired wall thickness, in particular a wall thickness that is greater than the wall thickness of the contact section 32 or the third web 34.

[0075] As a result, the webs 28, 30, 62 of the sealing section 26 have a higher sealing effect and have improved fire protection properties, so that additional fire protection elements, such as intumescent strips 52, can be dispensed with in the case of low fire protection requirements.

[0076] The Figure 6 The sealing device 20 shown is intended for a drywall 10 that is sheathed in two layers. This means that the drywall 10 has an interior first sheathing part 64 adjacent to the stud construction and a second sheathing part 66 adjacent to the first sheathing part 64, which forms the exterior of the drywall 10.

[0077] For this purpose, the support 36 has a width in the horizontal direction H which corresponds to twice the wall thickness of a planking part 12, 64, 66.

[0078] Of course, in an alternative embodiment, the sealing device 20 can be provided for a drywall 10 that is simply sheathed. In this case, the support 36 has a width in the horizontal direction H that corresponds to the wall thickness of a sheathing part 12, 64, 66.

[0079] Based on the Figure 7 A sealing device according to a further embodiment will now be described. The same reference numerals are used for the components known from the above embodiments, and reference is made to the previous explanations.

[0080] The Figure 7The sealing device 20 shown has a contact section 32 with a fourth web 68, which extends away from the support section 24 at a right angle to the second web 30. The second web 30 and the fourth web 68 are arranged at the same end of the support section 24 and thus lie in one plane.

[0081] As a result, the base body 22 has an H-shaped profile.

[0082] The two webs 34, 68 of the contact section 32 form a holding section 70 which can be plugged circumferentially onto a paneling part 12 in order to fasten the sealing device 20 to the paneling part 12.

[0083] The distance between the two webs 34, 68 of the contact section 32 in the horizontal direction H corresponds to the wall thickness of the planking part 12.

[0084] To facilitate insertion, the third web 34 has an insertion bevel 46.

[0085] During the installation of the drywall 10, the sealing device 20 is attached to the paneling part 12 using the retaining section 70. The sealing device 20 is pushed onto the paneling part 12 until the peripheral side 18 rests against the support section 24. The paneling part 12, together with the sealing device 20, is then attached to the stud construction of the drywall 10.

[0086] Based on the Figure 8 A sealing device according to a further embodiment will now be described. The same reference numerals are used for the components known from the above embodiments, and reference is made to the previous explanations.

[0087] In contrast to the Figure 7In the embodiment shown, the holding section 70 has two arcuate clamping jaws 72 which extend in the vertical direction V from the ends of the webs 34, 68 of the contact section 32, which are arranged opposite to the carrier section 24, and initially run towards one another in the horizontal direction H and then away from one another again.

[0088] Thus, a clamping zone 74 is formed between the two clamping jaws 72, in which a paneling part 12 is clamped when the sealing device 20 is placed onto the paneling part 12. In this way, the sealing device 20 can be reliably attached to the paneling part 12.

[0089] The free ends of the clamping jaws 72, which are bent away from each other, also form an insertion opening 76, which facilitates the attachment of the sealing device 20.

[0090] In this way, a sealing device 20 for an edge joint 16 of a drywall 10 is provided, which in all embodiments ensures simple installation of the sealing device 20 together with the erection of the stud construction.

[0091] Furthermore, the sealing section 26 ensures effective sealing of the edge joint 16 against air and sound.

[0092] The sealing device 20 transforms the drywall 10 into a fireproof construction, by means of which the spread of smoke, temperature and fire to the side of the drywall 10 facing away from the fire can be prevented.

[0093] The webs 28, 30 of the sealing section 26 ensure a defined joint width and also protect the planking part 12 against moisture in or on the floor 8, in particular during the construction phase.

[0094] Furthermore, the sealing device 20 is a factory-made application solution with consistent properties that facilitates the sealing of edge joints with consistently high quality.

[0095] The invention is not limited to the embodiments shown. In particular, individual features of one embodiment can be combined arbitrarily with features of other embodiments within the scope of the appended claims, in particular independently of the other features of the corresponding embodiments.

[0096] For example, all of the sealing elements shown in the different embodiments, such as the webs 28, 30, 62, the seal 50, the intumescent strip 52, the sealing rib 54 and the sealing lips 56, 58, can be combined in any number and in any manner within the scope of the appended claims in a further embodiment.

[0097] Furthermore, each contact section can be combined with any sealing section.

[0098] Furthermore, each sealing device can be designed for single or double planking.
