Description

[0027] The invention is explained below with reference to various embodiments which are shown in the accompanying drawings, in which:

[0028] FIG. 1 is a perspective view of a portion of a sealing element according to the invention,

[0029] FIG. 2 to 13 show different variants of the sealing element according to the invention in cross-sectional representations, the sealing element being cut along plane A in FIG. 1,

[0030] FIG. 14 to 24 show further variants of the sealing element according to the invention in cross-sectional representations, the sealing element being cut along plane A in FIG. 1,

[0031] FIGS. 25 and 26 show additional variants of the sealing element according to the invention in cross-sectional representations, the sealing element being cut along plane A in FIG. 1, and

[0032] FIG. 27 to 29 show sealing elements according to the invention in different installation situations.

[0033] FIG. 1 shows a sealing element 10 which is designed to seal a structural joint.

[0034] It comprises a first carrier layer 12 and a second carrier layer 14.

[0035] The two carrier layers 12, 14 are substantially flat.

[0036] In this case, at least one portion of an outer surface 13 of the first carrier layer 12 forms a first contact surface for contact with a boundary surface of the structural joint.

[0037] A portion of an outer surface 15 of the second carrier layer 14 forms a second contact surface for contact with a boundary surface of the structural joint.

[0038] The first carrier layer 12 and the second carrier layer 14 as a whole extend toward one another in a V shape in a cross-sectional view which is oriented perpendicularly to a longitudinal direction L of the sealing element 10 (cf. plane A). In this cross-sectional view, the two carrier layers 12, 14 are also substantially the same length.

[0039] They are connected to one another at the ends thereof that are closer together. This connection 16 is elastically flexible. Starting from the position shown in FIG. 1, the carrier layers 12, 14 can therefore be elastically deformed in such a way that the two carrier layers 12, 14 are moved toward one another.

[0040] A receiving space 18, in which a functional material 20 is received, is formed between the first carrier layer 12 and the second carrier layer 14.

[0041] In the following, variants of the sealing element 10 from FIG. 1 are explained with reference to FIG. 2 to 13.

[0042] In this context. FIG. 2 shows an embodiment in which the receiving space 18 is completely filled with a functional material 20.

[0043] The functional material 20 thus rests against both the first carrier layer 12 and the second carrier layer 14.

[0044] In this case, the functional material 20 is an intumescent material 22.

[0045] It is also elastically flexible.

[0046] In the embodiment of the sealing element 10 shown in FIG. 3, the same functional material 20 is used as in the embodiment according to FIG. 2.

[0047] In contrast to this, however, the functional material 20 only partially fills the receiving space 18. The region of the receiving space 18 which is oriented in the direction of the connection 16 is left free.

[0048] The embodiment according to FIG. 4 is a variant of the embodiments according to FIGS. 2 and 3. Again, the same functional material 20 is used, which again only partially fills the receiving space 18.

[0049] However, the functional material 20 is now arranged in a portion of the receiving space 18 which faces the connection 16.

[0050] Another variant of the sealing element 10 can be seen in FIG. 5.

[0051] In contrast to the embodiment according to FIG. 2, the functional material 20 is now a thermal insulation material 24. which is also a noise insulation material 26 at the same time.

[0052] This is achieved, for example, by the functional material 20 being mineral wool.

[0053] The receiving space 18 is again completely filled by the functional material 20.

[0054] In contrast to the previously described embodiments, a cover element 28 is now additionally provided which connects the ends of the carrier layers 12, 14 that are further apart from one another and covers the receiving space 18.

[0055] The functional material 20 is thus protected against the effects of dirt and moisture.

[0056] The cover element 28 can is also elastically deformable, so that it does not stand in the way of the carrier layers 12, 14 moving toward one another.

[0057] In the embodiment according to FIG. 6, the functional material 20 is again the intumescent material 22.

[0058] This is now introduced into the receiving space 18 in the form of a strip.

[0059] A first strip is applied to the first carrier layer 12.

[0060] A second strip of the functional material 20 is arranged on the second carrier layer 14.

[0061] The receiving space 18 is not filled between the strips of the functional material 20.

[0062] The embodiment from FIG. 7 is a development of the embodiment from FIG. 6.

[0063] In this variant, a further functional material 20 is arranged between the strips made of the intumescent material 22. Two different functional materials 20 are therefore provided in the receiving space 18.

[0064] The further functional material 20 can be a thermal insulation material 24, a noise insulation material 26, or a sealing material 30.

[0065] The embodiment according to FIG. 8 is based on the embodiment according to FIG. 7.

[0066] A spring element 32 separate from the functional materials 20 is arranged in the receiving space 18 and connects the first carrier layer 12 and the second carrier layer 14.

[0067] After they have been moved toward one another in the vertical direction in FIG. 8, the carrier layers 12, 14 can be elastically returned to their starting position by means of the spring element 32. The spring element 32 thus defines a contact force of the sealing element 10 in its mounted position.

[0068] As a result, the sealing element 10 rests particularly reliably against the associated boundary surfaces of the structural joint in the installed state.

[0069] The embodiment according to FIG. 9 is also based on the embodiment according to FIG. 7.

[0070] Here, both the first contact surface and the second contact surface are additionally provided with an adhesive coating 34.

[0071] As a result, the sealing element 10 can be held particularly reliably in an associated structural joint.

[0072] Furthermore, the embodiment from FIG. 10 is based on the embodiment according to FIG. 7.

[0073] In this variant, the end of the first carrier layer 12 which is further away from the second carrier layer 14 is equipped with a stop element 36.

[0074] The stop element 36 protrudes from the first carrier layer 12 in a direction pointing away from the second carrier layer 14.

[0075] It is designed to be placed against an edge of a structural joint, so that the stop element 36 prevents the sealing element 10 from being pushed too far into the structural joint.

[0076] In other words, the sealing element 10 can be precisely positioned in an associated structural joint by means of the stop element 36.

[0077] The embodiment according to FIG. 11 is a combination of the embodiments according to FIG. 5 and FIG. 10.

[0078] A cover element 28 is again provided, but in the embodiment according to FIG. 11 it is connected only to one end of the second carrier layer 14.

[0079] Proceeding from this, the cover element 28 extends over the receiving space 18 and over one end of the first carrier layer 12. As a result, the receiving space 18 is reliably covered and thus protected from undesirable influences of dirt.

[0080] The portion of the cover element 28 protruding beyond the first carrier layer 12 also acts as a stop element 36.

[0081] In other words, the sealing element 10 according to FIG. 11 has a combined stop element 36 and cover element 28.

[0082] The embodiment according to FIG. 12 is also based on the embodiment according to FIG. 7.

[0083] Three holding elements 38 in the form of holding fingers 40 are provided on each of the outer surfaces 13, 15.

[0084] When inserted into an associated structural joint, the holding fingers 40 are slightly deformed so that they hook onto the boundary surfaces of the structural joint.

[0085] The embodiment according to FIG. 13 is a variant of the embodiment according to FIG. 6, which is equipped with holding elements 38 in the form of holding fingers 40.

[0086] FIG. 14 to 24 show further embodiments of the sealing element 10.

[0087] In these variants, the carrier layers 12, 14 are designed in such a way that only portions 12a, 14a thereof extend toward one another in a V shape. Further portions 12b, 14b of the first carrier layer 12 and the second carrier layer 14 extend substantially parallel to one another.

[0088] The embodiment according to FIG. 14 otherwise corresponds to the embodiment according to FIG. 2. The receiving space 18, which is slightly enlarged due to the mutually parallel portions 12b, 14b of the carrier layers 12, 14, is again completely filled by an intumescent material 22.

[0089] Except for the differences in the design of the carrier layers 12, 14, the embodiment according to FIG. 15 corresponds to the embodiment according to FIG. 6, the intumescent material 22 again being strip-shaped.

[0090] In the embodiment according to FIG. 15, the intumescent material 22 is arranged only on the portions 12b, 14b of the carrier layers 12, 14 that extend parallel to one another.

[0091] The embodiment according to FIG. 16 substantially corresponds to the embodiment according to FIG. 5.

[0092] The embodiment according to FIG. 17 represents a further development of the embodiment according to FIG. 15, in which an adhesive coating 34 is provided in each of the parallel portions 12b, 14b of the carrier layers 12, 14.

[0093] The embodiment according to FIG. 18 is also a development of the embodiment according to FIG. 15.

[0094] A further functional material 20, which can be a thermal insulation material 24, a noise insulation material 26 or a sealing material 30, is now arranged in the portions of the receiving space 18 which are not occupied by the intumescent material 22.

[0095] The variant according to FIG. 19 combines the embodiments according to FIGS. 17 and 18.

[0096] In contrast to the embodiment according to FIG. 18, adhesive coatings 34 are again provided.

[0097] The embodiment according to FIG. 20 is based on the embodiment according to FIG. 17, a spring element 32 now being provided which is separate from the functional material 20 and connects the portions 12b, 14b of the carrier layers 12, 14 that extend parallel to one another.

[0098] The embodiment according to FIG. 21 differs from the variant from FIG. 20 in that an additional functional material 20 is arranged in the remaining portions of the receiving space 18.

[0099] The embodiment from FIG. 22 is a development of the embodiment from FIG. 17.

[0100] A stop element 36 is now arranged at each of the ends of the carrier layers 12, 14 that are further apart from one another.

[0101] The stop elements 36 each protrude outward from the sealing element 10.

[0102] The function of the stop elements 36 results as already explained in connection with FIG. 10.

[0103] The variant from FIG. 23 differs from the variant from FIG. 22 only in that an additional functional material 20 is arranged in the remaining portions of the receiving space 18.

[0104] The embodiment from FIG. 24 is a variant of the embodiment from FIG. 11.

[0105] The difference between these two embodiments is that in the variant from FIG. 24, the carrier layers 12, 14 have portions 12b, 14b extending parallel to one another. With regard to the combined cover element 28 and stop element 36. reference can be made to the statements relating to FIG. 11.

[0106] The sealing elements 10 explained above with reference to FIG. 2 to 24 each differ in one or more features. It goes without saying that the individual embodiments each relate to exemplary combinations of features. It is therefore easily conceivable to combine features of individual embodiments in a different way than is shown in the drawings.

[0107] FIGS. 25 and 26 show two additional embodiments of the sealing element 10, the carrier layers 12, 14 again as a whole extending toward one another in a V shape. In the following, only the differences compared to the embodiments already explained, in particular the embodiment according to FIG. 10, will be discussed.

[0108] In the variant according to FIG. 25, the carrier layers 12, 14 are substantially flat. In contrast to the previous embodiments, however, the cross section of the connection 16 is not pointed, but rather blunt. For this purpose, the connection 16 is formed by a connecting element connecting the carrier layers 12, 14.

[0109] The variant according to FIG. 26 is a modification of the variant from FIG. 25 in which the carrier layer 14 is slightly curved. In the cross-sectional view shown in FIG. 26, the carrier layer 14 is thus arcuate.

[0110] Otherwise, reference is made to the embodiments already explained.

[0111] In particular, the sealing elements 10 according to FIGS. 25 and 26 can be equipped with any functional material 20 or any combination of functional materials 20.

[0112] FIG. 27 to 29 relate to different installation situations for sealing elements 10. In this case, one or more sealing elements 10 is/are arranged in all variants in a structural joint 42 which is defined by assigned boundary surfaces 42a, 42b.

[0113] In the variant according to FIG. 27, the structural joint 42 is a joint between two wall portions 44, 46. The structural joint 42 extends vertically in this case.

[0114] The structural joint 42 is sealed on both sides by a sealing element 10, which is designed in accordance with the embodiment from FIG. 23.

[0115] It becomes clear here that the stop elements 36 each rest on an edge of the structural joint 42, so that the sealing elements 10 cannot be pushed further into the interior of the structural joint 42 than is shown in FIG. 27.

[0116] The installation situation from FIG. 28 relates to a structural joint 42 between a wall portion 48 and a ceiling portion 50. Such structural joints 42 are also referred to as head-of-wall joints.

[0117] This structural joint 42 is closed only on one side by means of a sealing element 10.

[0118] This is a sealing element 10 which, with regard to the combined cover element 28 and stop element 36, corresponds to the embodiment from FIG. 11.

[0119] In contrast to this embodiment, however, the functional material 20 provided in the receiving space 18 is an intumescent material 22 that is arranged in strips on the two carrier layers 12, 14.

[0120] The fact that in this sealing element 10 a stop element 36 is provided only on one side makes it ideal for use on a structural joint that is delimited at least on one side by a ceiling portion 50.

[0121] 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.

[0122] The installation situation shown in FIG. 29 also relates to the structural joint 42, which is formed between the wall portion 48 and the ceiling portion 50.

[0123] However, the structural joint 42 is now sealed on both sides by means of a sealing element 10. The sealing element 10 corresponds to the variant from FIG. 10.

[0124] Again, the stop elements 36 each rest on an edge of the structural joint 42, so that the sealing elements 10 cannot be pushed further into the interior of the structural joint 42 than is shown in FIG. 29.

[0125] The installation situations from FIGS. 28 and 29 can also be in a form rotated by 180°, the ceiling portion 50 then being a floor portion. In this case, reference is made to bottom-of-wall joints.
