Description

[0001] The invention relates to a sealing element for a building joint, comprising a first support layer and a second support layer. In a cross-sectional view oriented perpendicular to a longitudinal direction of the sealing element, the two support layers are essentially the same length. Furthermore, at least one section of the first support layer and at least one section of the second support layer converge in a V-shape.

[0002] V-shaped convergence means that at least one section of the first support layer is arranged at an acute angle to at least one section of the second support layer.

[0003] Such sealing elements are known from the prior art. The V-shaped, converging support layers serve to provide the sealing element with a certain degree of flexibility, allowing it to adapt to any relative movements that may occur at the interfaces of the construction joint. Such relative movements can result from settlement processes of the structure in which the construction joint is located. Alternatively, the flexibility can be used to compensate for variations in the width of the construction joint to be sealed. Therefore, such a sealing element can be used in construction joints whose width fluctuates within a certain range.

[0004] Construction joints must be designed not only for aesthetic reasons, but also for fire protection, acoustic insulation, and / or sealing against moisture and / or unwanted air exchange. These functions are partially achieved by specially designed sealing elements. For example, EP 3 584 381 A1 discloses a sealing element made of an intumescent material, thus serving as a fire-resistant seal. The sealing element from EP 3 584 381 A1 can have differently designed profiles, allowing it to be used in various types of construction joints.

[0005] To fulfill several of the aforementioned functions, a multi-part sealing assembly is generally required. In this regard, WO 2017 / 207252 A1 discloses a sealing cord containing an intumescent material, which serves as a seal against flue gas, water, and dust.

[0006] A sealing element according to the preamble of claim 1 is known from US patent 2011 / 123801 A1.

[0007] Furthermore, it is known to ensure the aforementioned functions by introducing essentially formless sealants or sealing pastes into the building joint. However, this is considerably more complex than inserting a prefabricated sealing element into the building joint.

[0008] Against this background, the object of the present invention is to provide a sealing element by means of which various sealing functions can be provided in a simple manner. In particular, the sealing element should be structurally simple so that it can be manufactured easily and cost-effectively. Furthermore, the installation of the sealing element in the building joint should be possible with minimal effort.

[0009] The problem is solved by a sealing element according to claim 1, or a sealing element of the type mentioned above, in which a receiving space is formed between the first and second support layers, and a functional material is contained within this receiving space. A functional material is understood to be a material that performs a certain function in connection with sealing a building joint. Examples of such functions include fire protection, thermal insulation, and sealing against moisture, foreign particles, and air exchange. Foreign particles include, for example, dust particles. A single functional material, fulfilling one or more functions, can be contained within the receiving space. It is also, of course, possible to contain several functional materials within the receiving space, each fulfilling the same or different functions. Such a sealing element has a simple structural design.This allows it to be manufactured simply and cost-effectively, especially as a continuous material. Furthermore, such a sealing element can fulfill various sealing functions. By accommodating functional materials within the receiving chamber that provide the desired functions, the sealing element can be easily adapted to different applications. Depending on the application, the receiving chamber can also be completely or only partially filled with the functional material. The fact that at least sections of the carrier layers converge in a V-shape ensures that the sealing element can be reliably positioned against the boundary layers of the construction joint. Moreover, this shape facilitates the insertion of the sealing element into the construction joint, as the V-shaped converging sections act as insertion ramps.Such a sealing element can also be used for a wide range of joint widths without needing to be modified.

[0010] The first and second support layers can comprise a polymer material. They are therefore made primarily of a plastic material, for example, polyvinyl chloride. Alternatively, the support layers can comprise a fiber material. Naturally, they can also be made of a metallic material or a composite material. Likewise, the first and second support layers can, in the broadest sense, comprise a paper or cardboard material and / or a cork material. It is also conceivable that the first and second support layers could comprise a wood material, particularly a bamboo material.

[0011] According to one embodiment, at least one section of the first support layer and at least one section of the second support layer are connected to each other at their respective closer ends. In particular, the first and second support layers are elastically compliant. In cross-section, the sealing element is therefore only open on one side. This makes it particularly easy to introduce and retain a functional material in the receiving space. The connected support layers preferably form a single-piece composite. This allows the sealing element to be manufactured relatively easily and cost-effectively. An elastically compliant connection enables the sealing element to be elastically compressed in the lateral direction of the associated structural joint. This facilitates its insertion into the joint.Furthermore, it is ensured with particularly high reliability that the sealing element fits snugly against the interfaces of the building joint.

[0012] Another section of the first support layer and another section of the second support layer can run essentially parallel to each other. Each of these further sections is connected, preferably integrally, to one of the V-shaped sections converging towards the other. In this way, a relatively large receiving space can be created. Accordingly, a comparatively large quantity of functional material can be contained within it. This results in a particularly resistant sealing element and / or a sealing element that can provide a particularly high range of functions. Furthermore, such a sealing element is designed to penetrate the structural joint to a comparatively great depth and provide a seal.

[0013] Preferably, the first and second support layers converge in a V-shape. This makes the sealing element particularly simple in design and extremely easy to manufacture. For example, the support layers can be produced using an extrusion process. In this context, the support layers can be flat.

[0014] According to the invention, a section of an outer surface of the first support layer forms a first contact surface for contact with an interface of the construction joint, and / or a section of an outer surface of the second support layer forms a second contact surface for contact with an interface of the construction joint. The first and second support layers thus lie directly against their respective interfaces of the construction joint, in particular without the interposition of further layers. This also contributes to the structurally simple design of the sealing element.

[0015] According to the invention, the first contact surface and / or the second contact surface is provided with an adhesive coating.

[0016] Such a coating serves to increase the static friction between the substrate and the corresponding interface of the construction joint. Alternatively or additionally, the adhesive coating serves to achieve improved adhesion of the substrate to a corresponding interface of the construction joint through adhesion. This ensures that the sealing element is reliably held in the construction joint.

[0017] In a further development, at least one retaining element is provided on the first contact surface and / or the second contact surface to hold the sealing element in the construction joint. The retaining element is, in particular, a retaining projection or a retaining finger. The sealing element is reliably held within the construction joint by means of this at least one retaining element. For this purpose, the retaining element is deformed, for example, so that sections of the retaining element interlock with the corresponding interface of the construction joint.

[0018] In one embodiment, the functional material comprises an intumescent material. Such a material swells under the influence of heat, thus increasing its volume. This allows the sealing element to provide a particularly reliable, fire-resistant seal. This is especially true for sealing against surfaces that are not perfectly flat.

[0019] Alternatively or additionally, the functional material includes a thermal insulation material. This reliably prevents or at least inhibits heat transfer through the building joint. The thermal insulation material includes, for example, mineral wool.

[0020] It is also possible that the functional material includes a sound-insulating material. The construction joint can thus be acoustically insulated. Such an insulating material can also include mineral wool.

[0021] The functional material can also include a sealing material. A sealing material serves to seal against smoke, air, moisture, foreign particles, and / or water. This allows the building joint to be reliably sealed in this respect.

[0022] It goes without saying that the functional materials described above can be used individually or in combination in the recording space. It is also possible for a single functional material, such as mineral wool, to fulfill several of the functions mentioned.

[0023] According to one design variant, the functional material rests against both the first and second support layers, and is elastically compliant. This allows the first and second support layers to be brought closer together by elastic deformation of the functional material. As soon as the applied force is released, the support layers return to their original position as the functional material elastically deforms back. The result is a sealing element that, for example, can be compressed to a dimension corresponding to the width of a building joint for insertion. This makes it particularly easy to insert the sealing element into the joint. Within the joint, the sealing element can then elastically deform back, resulting in a reliable seal at the interfaces of the joint.

[0024] Depending on the shape of the building joint, the re-deformation of the functional material can also lead to the sealing element being pulled into the building joint.

[0025] In this context, the functional material can exhibit higher elastic compliance than the support layers. In other words, the support layers are stiffer than the functional material. Such a design allows for targeted control of the elastic deformation of the sealing element with regard to the location and direction of deformation. Specifically, the sealing element can be configured so that the support layers are essentially non-elastic, and thus the elastic deformation of the sealing element results primarily from the elastic deformation of the functional material. This deformation occurs primarily along the entire length and / or width of the functional material. This allows the sealing element to be easily and reliably installed in a structural joint.Furthermore, a spring element, separate from the functional material, can be arranged in the receiving space, connecting the first and second support layers. This spring element can be elastically compressed by bringing the first and second support layers closer together. This results in the same functionality and advantages already described in connection with the elastically compliant functional material. A key advantage of using a spring element is that the actual functional material can be selected without regard to its elastic formability. Moreover, a spring element allows for a particularly high force to be applied, pressing the sealing element against the corresponding interfaces of the structural joint when installed.

[0026] Another variant provides for a stop element at at least one of the ends of the support layers that are further apart in the cross-sectional view, for contact with an edge of the construction joint. Preferably, this stop element projects away from the other support layer in the cross-sectional view, i.e., outwards from the sealing element. Such a stop element prevents the sealing element from being inserted too far into the construction joint. This results in a precise positioning of the sealing element within the construction joint.

[0027] Furthermore, a cover element can be arranged at at least one of the ends of the support layers that are further apart in the cross-sectional view to cover the receiving space. For this purpose, the cover element can extend from one end of one of the support layers towards the other support layer, i.e., towards the receiving space. Naturally, the cover element can also be connected to the ends of both support layers. Preferably, the cover element is elastically deformable. In all variants, the cover element serves to protect the receiving space and the functional material arranged therein from dirt and / or moisture. The cover element can be attached to the at least one support layer as a solid or sprayed in liquid form onto the functional material and the corresponding ends of the support layers.This is done in particular before the sealing element is installed, so that it is already fitted with the cover element during assembly. The spraying can take place during the manufacturing of the sealing element or on a construction site. The result is a particularly durable sealing element overall. This also applies especially to the assembly process.

[0028] If the cover element originates from only one of the support layers, it can extend beyond the other support layer. In this case, the cover element can also act as a stop element to prevent the sealing element from being inserted too deeply into a building joint.

[0029] The invention is explained below with reference to various embodiments shown in the accompanying drawings. Sealing elements according to the invention are shown in the Figure 9 , 17 , 19-23 and 27 shown. They show: Figure 1 a section of a sealing element in a perspective view, Figures 2 to 13 Different variants of a sealing element in cross-sectional views, wherein the sealing element is shown along plane A in Figure 1 was cut Figures 14 to 24 Further variants of a sealing element in cross-sectional views, wherein the sealing element extends along plane A in Figure 1 was cut Figures 25 and 26 Additional variants of a sealing element in cross-sectional representations, wherein the sealing element extends along plane A in Figure 1 was cut, and Figures 27 to 29 Sealing elements in various installation situations.

[0030] Figure 1 shows a sealing element 10 designed to seal a building joint.

[0031] It comprises a first support layer 12 and a second support layer 14. Both support layers 12, 14 are essentially flat.

[0032] In this case, at least one section of an outer surface 13 of the first support layer 12 forms a first contact surface for attachment to a boundary surface of the building joint.

[0033] A section of an outer surface 15 of the second support layer 14 forms a second contact surface for attachment to a boundary surface of the building joint.

[0034] In a cross-sectional view oriented perpendicular to a longitudinal direction L of the sealing element 10 (see plane A), the first support layer 12 and the second support layer 14 converge in a V-shape as a whole.

[0035] In this cross-sectional view, the two support layers 12, 14 are also essentially the same length.

[0036] They are connected to each other at their respective closer ends. This connection 16 is elastically flexible. The support layers 12, 14 can therefore be extended from the in Figure 1The position shown is deformed elastically in such a way that the two support layers 12, 14 are moved towards each other.

[0037] Between the first support layer 12 and the second support layer 14 a receiving space 18 is formed in which a functional material 20 is received.

[0038] The following will be based on the Figures 2 to 13 Variants of the sealing element 10 made of Figure 1 explained.

[0039] In this context, the Figure 2 an embodiment in which the receiving space 18 is completely filled with a functional material 20.

[0040] The functional material 20 is thus in contact with both the first support layer 12 and the second support layer 14.

[0041] In this case, the functional material 20 is an intumescent material 22.

[0042] Furthermore, it is elastically flexible.

[0043] At the in Figure 3In the illustrated embodiment of the sealing element 10, the same functional material 20 is used as in the embodiment according to Figure 2 .

[0044] In contrast, the functional material 20 only partially fills the reception space 18. The area of ​​the reception space 18 oriented towards the connection 16 is left empty.

[0045] The embodiment according to Figure 4 represents a variant of the embodiments according to Figures 2 and 3 The same functional material 20 is used again, which again only partially fills the recording space 18.

[0046] However, the functional material 20 is now arranged in a section of the receiving space 18 that faces the connection 16.

[0047] Another variant of the sealing element 10 is in Figure 5 to see.

[0048] In contrast to the embodiment according to Figure 2The functional material 20 is now a thermal insulation material 24, which is also a sound insulation material 26.

[0049] This is achieved, for example, by using mineral wool as the functional material 20.

[0050] The recording room 18 is again completely filled with functional material 20.

[0051] In contrast to the embodiments described above, an additional cover element 28 is now provided, which connects the ends of the support layers 12, 14 that are further apart from each other and covers the receiving space 18.

[0052] The functional material 20 is thus protected against the effects of dirt and moisture.

[0053] The cover element 28 is also more elastically malleable, so that it does not impede the movement of the support layers 12, 14 towards each other.

[0054] In the embodiment according to Figure 6The functional material 20 is again the intumescent material 22.

[0055] This has now been placed in recording room 18 in a strip-like form.

[0056] A first strip is applied to the first carrier layer 12.

[0057] A second strip of the functional material 20 is arranged on the second carrier layer 14.

[0058] The space between the strips of functional material 20 is not filled with the recording space 18.

[0059] The embodiment from Figure 7 represents a further development of the embodiment Figure 6 dar.

[0060] In this variant, another functional material 20 is arranged between the strips of intumescent material 22. Thus, two different functional materials 20 are provided in the receiving chamber 18.

[0061] The additional functional material 20 can be a thermal insulation material 24, a sound insulation material 26 or a sealing material 30.

[0062] The embodiment according to Figure 8 based on the embodiment according to Figure 7 .

[0063] In the receiving chamber 18, a spring element 32, separate from the functional materials 20, is arranged, which connects the first support layer 12 and the second support layer 14.

[0064] The spring element 32 allows the support layers 12, 14 to be moved after they have been placed in the Figure 8 Having been moved vertically towards each other, they are elastically returned to their initial position. The spring element 32 thus defines a contact force on the sealing element 10 in its mounted position.

[0065] This ensures that the sealing element 10, when installed, fits particularly reliably against the assigned interfaces of the building joint.

[0066] The embodiment according to the invention is also shown. Figure 9 based on the embodiment according to Figure 7 .

[0067] Now, in addition, both the first and second mounting surfaces are provided with an adhesive coating 34.

[0068] This allows the sealing element 10 to be held particularly reliably in an assigned building joint.

[0069] Furthermore, the exemplary embodiment is based on Figure 10 based on the embodiment according to Figure 7 .

[0070] In this variant, the end of the first support layer 12 that is further away from the second support layer 14 is equipped with a stop element 36.

[0071] The stop element 36 is positioned in a direction away from the first support layer 12, pointing away from the second support layer 14.

[0072] It is designed to be placed against the edge of a building joint, so that the stop element 36 prevents the sealing element 10 from being inserted too deeply into the building joint.

[0073] In other words, the sealing element 10 can be precisely positioned in an associated building joint by means of the stop element 36.

[0074] The embodiment according to Figure 11 is a combination of the embodiments according to Figure 5 and Figure 10 .

[0075] A cover element 28 is now provided again, but in the embodiment according to Figure 11 is connected only to one end of the second support layer 14.

[0076] From this point, the cover element 28 extends over the receiving space 18 and over one end of the first support layer 12. This ensures that the receiving space 18 is reliably covered and thus protected from unwanted influences such as dirt.

[0077] The section of the cover element 28 extending beyond the first support layer 12 also acts as a stop element 36.

[0078] In other words, the sealing element 10 exhibits according to Figure 11 a combined stop element 36 and cover element 28.

[0079] The embodiment according to Figure 12 is also based on the embodiment according to Figure 7 .

[0080] Three retaining elements 38 in the form of retaining fingers 40 are provided on each of the outer surfaces 13, 15.

[0081] When inserted into a corresponding structural joint, the retaining fingers 40 are slightly deformed so that they hook onto the interfaces of the structural joint.

[0082] The embodiment according to Figure 13 represents a variant of the embodiment according to Figure 6 which is equipped with retaining elements 38 in the form of retaining fingers 40.

[0083] The Figures 14 to 24further embodiments of the sealing element 10 are shown.

[0084] In these variants, the support layers 12, 14 are designed such that only sections 12a, 14a of each converge in a V-shape. Further sections 12b, 14b of the first support layer 12 and the second support layer 14 run essentially parallel to each other.

[0085] The embodiment according to Figure 14 Otherwise corresponds to the embodiment according to Figure 2 The receiving chamber 18, which is slightly enlarged due to the parallel sections 12b, 14b of the support layers 12, 14, is again completely filled with an intumescent material 22.

[0086] The embodiment according to Figure 15 Except for the differences in the design of the support layers 12, 14, it corresponds to the embodiment according to Figure 6 , whereby the intumescent material 22 is again strip-shaped.

[0087] In the embodiment according to Figure 15 The intumescent material 22 is arranged only on the parallel sections 12b, 14b of the support layers 12, 14.

[0088] The embodiment according to Figure 16 essentially corresponds to the embodiment according to Figure 5 .

[0089] The embodiment according to the invention according to Figure 17 represents a further development of the embodiment according to Figure 15 a bonding coating 34 is provided in each of the parallel sections 12b, 14b of the carrier layers 12, 14.

[0090] The embodiment according to Figure 18 represents a further development of the embodiment according to Figure 15 dar.

[0091] Now, in those sections of the reception area 18 that are not covered by the intumescent material 22, a further functional material 20 is arranged, which may be a thermal insulation material 24, a sound insulation material 26 or a sealing material 30.

[0092] The variant according to the invention Figure 19 combines the embodiments according to Figure 17 and 18 .

[0093] In contrast to the embodiment according to Figure 18 So, adhesive coatings 34 are now planned again.

[0094] The embodiment according to the invention according to Figure 20 based on the embodiment according to the invention Figure 17 , wherein a spring element 32 separate from the functional material 20 is now provided, which connects the parallel sections 12b, 14b of the support layers 12, 14.

[0095] The embodiment according to the invention according to Figure 21This differs from the variant according to the invention. Figure 20 , that an additional functional material 20 is arranged in the remaining sections of the recording room 18.

[0096] The embodiment according to the invention made of Figure 22 is a further development of the embodiment of the invention made up of Figure 17 .

[0097] Now, a stop element 36 is arranged at each of the more distant ends of the support layers 12, 14.

[0098] The stop elements 36 each point outwards away from the sealing element 10.

[0099] The function of the stop elements 36 is as already explained in connection with the Figure 10 explained.

[0100] The variant according to the invention made of Figure 23 differs from the variant according to the invention only in that it is made of Figure 22, that an additional functional material 20 is arranged in the remaining sections of the recording room 18.

[0101] The exemplary embodiment from Figure 24 is a variant of the embodiment from Figure 11 .

[0102] The difference between these two embodiments lies in the fact that in the variant made of Figure 24 The support layers 12, 14 have parallel sections 12b, 14b. Regarding the combined cover element 28 and stop element 36, reference can be made to the explanations concerning Figure 11 be referred.

[0103] The above based on the Figures 2 to 24The sealing elements 10 described above each differ by one or more features. It is understood that the individual embodiments each represent exemplary combinations of features. It is therefore entirely conceivable to combine features of individual embodiments in a different way than shown in the figures.

[0104] The Figures 25 and 26 Two additional embodiments of the sealing element 10 are shown, wherein the support layers 12, 14 again converge in a V-shape as a whole. The following discussion focuses solely on the differences compared to the embodiments already described, in particular the embodiment according to Figure 10 , received.

[0105] In the variant according to Figure 25The support layers 12, 14 are essentially flat. However, unlike the previous embodiments, the connection 16 is not pointed in cross-section, but blunt. For this purpose, the connection 16 is formed by a connecting element that joins the support layers 12, 14.

[0106] The variant according to Figure 26 presents a variation of the variant Figure 25 the support layer 14 is slightly curved. In the Figure 26 In the cross-sectional view shown, the support layer 14 is therefore arc-shaped.

[0107] Furthermore, reference is made to the embodiments already explained.

[0108] In particular, the sealing elements 10 can be used according to Figures 25 and 26 be equipped with any functional material 20 or any combination of functional materials 20.

[0109] The Figures 27 to 29These relate to different installation situations for sealing elements 10. In all variants, one or more sealing elements 10 are arranged in a building joint 42, which is defined by associated interfaces 42a, 42b.

[0110] In the inventive variant according to Figure 27 The structural joint 42 is a joint between two wall sections 44, 46. The structural joint 42 runs vertically.

[0111] The building joint 42 is sealed on both sides by a sealing element 10, which is exemplified according to the embodiment of the invention. Figure 23 is designed.

[0112] It becomes clear that the stop elements 36 each abut an edge of the building joint 42, so that the sealing elements 10 cannot be inserted further into the interior of the building joint 42 than is possible in the Figure 27 is shown.

[0113] The installation situation from Figure 28 This concerns a structural joint 42 between a wall section 48 and a ceiling section 50. Such structural joints 42 are also referred to as head-of-wall joints.

[0114] This structural joint 42 is only closed on one side by means of a sealing element 10.

[0115] This is a sealing element 10, which, with regard to the combined cover element 28 and stop element 36 of the embodiment, consists of Figure 11 corresponds.

[0116] In contrast to this embodiment, the functional material 20 provided in the receiving space 18 is an intumescent material 22, which is arranged in strip form on both support layers 12, 14.

[0117] The fact that this sealing element 10 has a stop element 36 provided only on one side makes it ideal for use on a building joint that is limited on at least one side by a ceiling section 50.

[0118] An additional stop element 36 provided on the other side of the sealing element 10 would only interfere with the installation of the sealing element 10.

[0119] Even those in Figure 29 The installation situation shown relates to the building joint 42, which is formed between the wall section 48 and the ceiling section 50.

[0120] However, the construction joint 42 is now sealed on both sides by means of a sealing element 10. The sealing element 10 corresponds to the variant from Figure 10 .

[0121] Again, the stop elements 36 are each located at one edge of the building joint 42, so that the sealing elements 10 cannot be pushed further into the interior of the building joint 42 than is possible in Figure 29 is shown.

[0122] The installation situations from the Figures 28 and 29 They can also exist in a form rotated by 180°, in which case ceiling section 50 is a floor section. These are then referred to as bottom-of-wall joints.
