Description

[0001] Dichtmanschette

[0002] The invention relates to a sleeve for fluid-tight closure of a penetration point of a line through a wall, in particular a floor slab and / or building floor slab and / or building exterior wall and / or roof surface wall, comprising a base plate which can be placed against the wall and extends into a connection plane and has an inner edge delimiting a recess in the base plate, wherein the base plate is made of a fluid-tight plastic, and comprising a connection membrane which adjoins the inner edge and projects beyond the recess of the base plate at least in sections and is made of a flexible and likewise fluid-tight plastic, wherein the connection membrane has an annular contact collar which is designed to be applied to the line in a fluid-tight manner on the jacket side, and wherein the base plate is made of a first plastic material and the connection membrane is made of a different, second plastic material,wherein the second plastic material has a higher flexibility than the first plastic material.,

[0003] A generic sealing sleeve is known, for example, from DE 199 25 623 A1, GB 2230062 A, EP 3 135 973 A1, and US 2015 / 054229 A1. It is used, for example, in building construction to guide cables, in particular pipelines or electrical cables, through an air-tight or diffusion-tight building envelope. For this purpose, the sealing sleeve is typically connected to the base plate in an air-tight or diffusion-tight manner to a film used for sealing. The connection can be made, for example, by gluing or welding. The cable is guided through a cable feed-through opening provided on the connection membrane of the sealing sleeve.The connecting membrane, which is enclosed by the base plate and protrudes inward from the base plate, fits snugly against the pipe shell with the contact collar, preventing air or moisture exchange at the penetration point. The connecting membrane and the base plate of the sealing sleeve are typically made of a single material, preferably a sufficiently elastic plastic, such as ethylene propylene diene rubber (EPDM). Optionally, the sleeve can have an adhesive collar or, depending on the application, a special lamination. For example, a sealing sleeve with a radon protection layer is known from DE 202020 106 793 U1.

[0004] The object of the present invention is to provide an improved sealing sleeve.

[0005] To achieve the object, the invention in conjunction with the features of the preamble of patent claim 1 is characterized in that support webs, preferably elongated, are provided on the base plate, projecting inwards from the inner edge in the direction of the contact collar, with an upper side facing the connection membrane, wherein the connection membrane rests with an inner surface thereof against the upper side of the support webs and a length of the support webs is determined such that the support webs end in front of the contact collar, and that the base plate and the support webs are made in one piece from the same first plastic material.

[0006] The particular advantage of the invention is that the support webs provide additional stability to the connection membrane. The sealing function of the connection membrane is not impaired because the support webs are recessed in the area of ​​the contact collar and, thanks to their slim, elongated design, do not unduly impair the deformability of the connection membrane. In particular, the support webs can provide additional stability to a large-area connection membrane made of a soft plastic material. The two different plastic materials enable a functionally optimized design of the sleeve. The base plate, made from the first, harder, or less flexible plastic material, gives the sleeve dimensional stability. This simplifies the installation of the sleeve and its connection to the airtight or diffusion-tight building envelope.In addition, the added dimensional stability simplifies handling of the sealing sleeve during production and logistics. The softer or more flexible second plastic material used for the connection membrane, on the other hand, is selected to provide an ideal sealing function while ensuring sufficient flexibility during installation of the line. Mechanical dimensional stability takes a back seat here, as the flexible connection membrane made from the second plastic material is encompassed by the dimensionally stable base plate. For example, the line can be oriented at an angle or slant to the connection plane. The soft, flexible connection membrane then creates the air-tight or diffusion-tight connection to the line on the one hand and the base plate on the other. At the same time, the flexibility counteracts the introduction of forces into the base plate.

[0007] According to a preferred embodiment of the invention, the base plate and the support webs are made in one piece from the same first plastic material. This advantageously simplifies the manufacturing process of the cuff. Furthermore, the cuff can be designed particularly cost-effectively.

[0008] According to a further development of the invention, the support webs are designed to be wave-shaped or S-shaped in a connection area thereof, by which they are connected to the base plate of the sealing sleeve. Advantageously, the wave-shaped or S-shaped support webs in the connection area result in high elasticity and flexibility of the support webs relative to the base plate. The support webs can therefore be deformed and, in particular, expanded, i.e., pivoted away from the connection plane, even if they are made of the same dimensionally stable first plastic material as the base plate itself. This advantageously makes it possible to use one and the same sealing sleeve for lines with very different diameters.As a result, the number of variants in which the sealing sleeve must be manufactured in order to guide cables of different thicknesses through the air-tight or diffusion-tight building envelope is reduced. For example, a first embodiment of the sealing sleeve can be used to guide cables with a diameter of 4 to 20 mm through the sealing skin. Furthermore, cables with a diameter range of 20 to 50 mm can be guided through the air-tight or diffusion-tight building envelope in an air-tight or diffusion-tight manner using a second embodiment, from 50 to 100 mm using a third embodiment, and from 100 to 180 mm using a fourth embodiment of the sealing sleeve.

[0009] For example, the sealing collar may provide five, six, seven, eight, nine, ten, or twelve support ribs evenly distributed in a circumferential direction. A sealing collar used to route smaller-diameter pipes through the air-tight or diffusion-tight building envelope may, for example, provide fewer support ribs than a sealing collar for larger-diameter pipes.

[0010] The raised support rods on the inner surface of the connecting membrane allow them to serve as a guide or sliding aid for the lines, particularly in sealing sleeves that accommodate lines of different diameters and therefore require different expansion during installation. They reduce friction between the sealing sleeve and the line and thus also the forces that occur during installation.

[0011] According to a further development of the invention, the sleeve is manufactured as a single-piece, two-component injection-molded part. This single-piece manufacturing process advantageously allows for particularly cost-effective production of the sleeve. Furthermore, assembly effort is reduced, or even eliminated entirely.

[0012] According to a further development of the invention, the base plate is made of a weldable plastic, namely a thermoplastic, or a thermoset. Thermoplastic and thermoset materials are characterized by good processability, stability or strength advantageous for the application, and longevity in terms of airtightness or diffusion tightness. Furthermore, the thermoplastic can be welded to the airtight or diffusion-tight building envelope, thus creating a tightly bonded, material-tight connection between the sealing sleeve and the building envelope. In this case, a separate connecting component, such as an adhesive film, can be dispensed with.

[0013] According to a further development of the invention, the connecting membrane is made of an elastomer. In particular, the connecting membrane can be made of rubber or a thermoplastic elastomer. The elastomer is advantageously characterized by high flexibility and good air and diffusion tightness. Furthermore, it can be processed in combination with the thermoset or thermoplastic of the base plate using a two-component injection molding process.

[0014] According to a further development of the invention, the connecting membrane has local longitudinal thickenings on an outer surface opposite the inner surface. In particular, the longitudinal thickenings extend, at least in sections, toward the support webs, the upper sides of which rest against the inner surface of the connecting membrane. The longitudinal thickenings locally improve the strength and resistance of the connecting membrane. This improvement is particularly effective where the support webs can cause greater mechanical stress on the connecting membrane during pipe assembly.

[0015] According to a further development of the invention, at least one circumferential annular thickening is provided on the outer surface of the connecting diaphragm. This circumferential annular thickening provides the connecting diaphragm with additional mechanical stability and strength. It can be used, in particular, to further increase the resistance of the connecting diaphragm and absorb higher tensile or shear forces acting in the circumferential direction.

[0016] According to a preferred embodiment of the invention, the support webs, together with the longitudinal thickenings and one or more annular thickenings, can form a cage structure for the connecting membrane. The cage structure provides stability to the connecting membrane while maintaining its flexibility. It can serve as a strain relief and thus prevent damage to the sealing sleeve during assembly or disassembly of the line. Furthermore, the cage structure can improve the tolerance with regard to the orientation of the line in the sealing sleeve.

[0017] According to a further development of the invention, the connecting diaphragm rises from the connecting plane in a truncated cone shape. The truncated cone shape of the connecting diaphragm has proven effective for routing lines of different diameters through the sleeve in the direction of the tapered truncated cone. Furthermore, the truncated cone shape prevents assembly errors and improves the flexibility of the connecting diaphragm.

[0018] According to a further development of the invention, the support webs, which follow the contour of the connecting membrane, are provided at least in sections inclined at a base angle of 30 to 75° to the connecting plane. The inclination of the support webs is preferably oriented towards the truncated cone shape of the connecting membrane. At the same time, the support webs, which are raised relative to the inner surface of the connecting membrane, can have a friction-reducing effect during assembly. The cable thus slides along the support webs made of the comparatively hard first plastic material. Surface contact with the soft, second plastic material of the connecting membrane is prevented or reduced.

[0019] According to a further development of the invention, the connection membrane is designed as an open connection membrane. As an open connection membrane, it provides a cable feedthrough opening for the cable, enclosed by the contact collar. The cable feedthrough opening is preferably provided concentrically with the recess in the base plate. The factory-prepared cable feedthrough opening advantageously simplifies the installation of the cable to be sealed on site.

[0020] According to an alternative embodiment of the invention, the connection membrane is designed as a closed connection membrane. The closed

[0021] The connection membrane does not have a factory-prepared cable entry opening. For the closed connection membrane, the cable entry opening is best manufactured on-site and can be customized to the specific cable diameter.

[0022] According to a further development of the invention, the closed connection membrane can have a predetermined breaking point enclosed by the contact collar. This predetermined breaking point simplifies the creation of the cable feedthrough. For example, a perforation or a material taper can serve as the predetermined breaking point. The perforation or taper can be annular or cross-shaped, for example.

[0023] According to a further development of the invention, the connecting membrane provides an injector connection piece in the area of ​​the outer wall of the surface. The injector connection piece can be made, in particular, from the second plastic material. The injector connection piece serves to inject a hardening, self-expanding, swellable, and / or self-sealing or permanently porous substance, which leads to improved tightness or, in the event of a fault or damage, restores lost tightness. The self-expanding effect or swelling effect can, for example, be thermally activated or caused by the ingress of moisture or wetness.

[0024] According to a further development of the invention, the sealing effect of the sealing sleeve can be further improved by placing a clamp or clamp in the area of ​​the connection collar after the cable has been passed through from the outside, with which the contact collar of the connection sleeve is pressed against the outer surface of the cable.

[0025] According to a further development of the invention, the base plate has a bent edge that extends straight in the connection plane and is arranged at a distance from the recess and its inner edge. The bent edge can be designed, for example, as a film hinge. The provision of the bent edge simplifies the installation of the sealing sleeve in room corners or on edges by bringing the base plate up to the edge at an angle of typically up to 90° or installing it into the corner. According to a further development of the invention, the sealing sleeve preferably has a centering aid on the base plate. The centering aid enables automated handling of the sleeve during production, packaging and / or assembly. For example, two notches spaced apart from one another on an outer edge of the base plate can serve as a centering aid. The notches can, for example, be formed as part of the bent edge.

[0026] According to a further development of the invention, a heating coil or an induction wire is incorporated into the base plate of the sealing sleeve. By providing the electrically energizable heating coil or the induction wire, the sleeve can be welded or bonded to the air-tight or diffusion-tight building envelope in a simple, reliable, and reproducible manner. A suitable welding device can be used to create the connection, which can be adjusted or operated in such a way that a defined energy input over a defined period of time ensures a tight connection between the sleeve and the building envelope.

[0027] According to a further development of the invention, the sealing sleeve comprises a functional component integrated into the base plate. A sensor for measuring temperature, pressure, and / or humidity can serve as a functional component, for example. The provision of the sensor can advantageously detect a leak or moisture ingress. For example, a data chip can be provided as a functional component, which stores sleeve-related information such as the manufacturing date or process-related data such as the installation date or the installation parameters. For example, a transponder can be provided as a functional component, which can be used to locate a sealing sleeve concealed in the building.

[0028] According to a further development of the invention, the sleeve as a whole or its base plate or connecting membrane are designed symmetrically with respect to an axis of symmetry extending perpendicular to the connecting plane and / or symmetrically with respect to an axis of symmetry oriented perpendicular to the connecting plane. The support webs and the connecting collar can also be arranged or provided symmetrically with respect to the axis of symmetry or the plane of symmetry. The symmetrical design advantageously simplifies handling of the sealing sleeve. At the same time, the symmetry counteracts incorrect assembly.

[0029] According to a further development of the invention, the sealing sleeve is designed as a double or multiple sleeve. The sealing sleeve therefore provides one or more connecting membranes, each preferably with one or more cable feedthrough openings or predetermined breaking points. The number of recesses in the base plate corresponds to the number of connecting membranes. By providing the double or multiple membrane, several lines can advantageously be passed through a single sealing sleeve and individually sealed. For example, it can be provided that the double or multiple sleeve provides a single, factory-prefabricated cable feedthrough opening as standard and, in addition, several predetermined breaking points are provided in order to create the necessary number of cable feedthrough openings on site as required.

[0030] According to a further development of the invention, the second plastic material used for the connecting membrane has a friction-reducing surface made of friction-reducing materials such as talc, silicone, paraffin, or glycol. This advantageously simplifies the installation of the line and prevents damage to the connecting membrane during assembly. The soft, second plastic material can, for example, be self-lubricating.

[0031] According to a further development of the invention, the support webs provide a friction-reducing surface coating. Alternatively, the first plastic material from which the base plate and / or the support webs can be made contains friction-reducing ingredients, for example, talc, silicone, paraffin, or glycol.

[0032] According to a further development of the invention, the first and / or second plastic material can contain modified ingredients suitable for visually indicating a change in the condition of the sealing sleeve. For example, ingredients can be provided that change their color depending on a change in temperature, material aging, or the ingress of moisture or wetness.

[0033] According to a further development of the invention, a contact bead can be formed on an outer edge of the contact collar facing away from the inner edge of the recess. Like the longitudinal or annular projection, the contact bead can be achieved by locally increasing the material thickness of the connecting membrane. The connecting bead locally improves the contact of the contact collar with the line. At the same time, it increases the ability of the connection membrane to absorb forces in the circumferential direction and thus prevents damage to the connecting membrane during installation of the line. The contact bead can be provided in the area of ​​the inner surface and / or in the area of ​​the outer surface of the connecting membrane.

[0034] According to a further development of the invention, the base plate of the sealing sleeve has a surface structure on its top and / or bottom side. The top and / or bottom side of the base plate can also be roughened. The structuring or targeted elevation can advantageously improve the weldability or adhesive properties of the sealing sleeve, resulting in a particularly secure seal between the sleeve and the air-tight or diffusion-tight building envelope.

[0035] In a preferred embodiment, the sealing sleeve can be used to guide cables with a circular diameter through the air-tight or diffusion-tight building envelope. For this purpose, it preferably provides a cable feedthrough opening with a circular cross-section or predetermined breaking points that serve to create a cable feedthrough opening with a circular cross-section. Alternatively, it is possible to seal cables with any other cross-section, for example, an oval cross-section or a rectangular cross-section, using the sealing sleeve. Furthermore, the sealing sleeves can be used flexibly in civil and structural engineering, for example, in tunnel construction.

[0075] Fig. 41 a sectional view of the sealing sleeve in the 16th embodiment.

[0076] A first embodiment of a sealing sleeve 1, shown in Figs. 1 to 4, comprises a substantially disc-shaped base plate 10 with an internal recess 12 extending in a connection plane 11. Furthermore, the sleeve 1 comprises a connection membrane 30, which adjoins an inner edge 13 of the recess 12 and partially covers the recess 12.

[0077] The base plate 10 of the cuff 1 is made of a first plastic material, and the connecting membrane 30 is made of a second plastic material. The second plastic material used for the connecting membrane 30 has greater flexibility and thus lower strength than the first plastic material from which the base plate 10 is made. Preferably, the base plate 10 is made of a thermoplastic or a thermoset, whereas the connecting membrane 30 is made of an elastomer.

[0078] The base plate 10 has a substantially constant thickness. It serves to connect the sealing sleeve 1 to a building's air-tight or diffusion-tight building envelope (not shown). The air-tight or diffusion-tight building envelope is formed, for example, by an air-tight or diffusion-tight film.

[0079] A total of eight support webs 20 are provided on the base plate 10, projecting inward from the inner edge 13. The support webs 20 are evenly distributed in a circumferential direction 4 of the base plate 10. They are longitudinally extended and slender. Like the base plate 10, they are made of the first plastic material and are integrally connected to the base plate 10. Fig. 5 shows a base body of the sealing sleeve 1 formed by the base plate 10 and the support webs 20, which is made entirely of the first plastic material.

[0080] The support webs 20 rise with the connecting membrane 30 of the sealing sleeve 1 to an upper side 18 of the base plate 10 from the connecting plane 11, so that the connecting membrane 30 is frustoconical in a basic shape shown in Figs. 1 to 4.

[0081] The connecting membrane 30 made of the flexible second plastic material rests with an inner surface 31 thereof against an upper side 21 of the support arms 20 facing the connecting membrane 30. The support arms 20 thus support the connecting membrane 30 and provide its surface stability.

[0082] The length of the support webs 20 of the base body is determined such that they end before a contact collar 40 of the connecting membrane 30. The contact collar 40 is formed as an annular part of the connecting membrane 30 and is designed to be tightly applied on the shell side to a cable that is to be passed through a penetration point of the air-tight or diffusion-tight building envelope. The contact collar 40 surrounds a cable feed-through opening 35 formed in the connecting membrane 30 for the cable, through which the cable is passed during installation. The base plate 10 of the sealing membrane 1 rests with an underside 17 thereof against a wall of the building, in particular against a floor slab, a building floor slab, an exterior building wall, or a roof wall, or is supported against it.

[0083] The support webs 20 are formed in a wave-shaped or S-shaped manner in a connection area 22, by which they are connected to the base plate 10 of the sleeve 1 in the area of ​​the inner edge 14. The wave-shaped or S-shaped configuration of the support webs 20 in the connection area 22 ensures that the elongated and slender support webs 20 are held in place on the base plate 10 in a flexible and deformable manner. The flexible arrangement of the support webs 20 ensures that they hold and support the connection membrane 30. On the other hand, the functionally necessary flexibility of the sleeve 1 is retained in the area of ​​the connection membrane 30, and it is possible to tightly apply the sealing sleeve 1 to lines with a different diameter or a different cross-sectional geometry.

[0084] The connecting membrane 30 has various thickenings on an outer surface 32 opposite the inner surface 31.

[0085] Firstly, a plurality of longitudinal thickenings 33 are provided, which extend longitudinally in sections on the outer shell surface 32, corresponding to the position of the support webs 20, and ensure that the material thickness of the connecting membrane 30 is locally increased where the support webs 20 support it on the inner shell side. The longitudinal thickenings 33 thus contribute to increasing the robustness and resistance of the connecting membrane 30 locally where greater forces can act due to the support webs 20, and to counteract damage to the connecting membrane 30, which could lead to leaks or a reduction in its service life.

[0086] In addition, on the outer surface 32 of the connection membrane 30 there is a

[0087] The annular thickening 34 is formed. The annular thickening 34 is implemented circumferentially. It serves as a strain relief and contributes to the particularly advantageous absorption of tensile or gravitational forces acting in the circumferential direction of the connecting membrane 30. The annular thickening 34, like the longitudinal thickenings 33, is formed by a local increase in the material thickness of the connecting membrane 30.

[0088] The thickened portions 33, 34 are made of the first plastic material as part of the connecting membrane and, in this respect, like the connecting membrane 30 as a whole.

[0089] The contact collar 40, which is formed as part of the connecting membrane 30 and surrounds a cable feedthrough opening 35 formed by the connecting membrane 30, has a contact bead 41 on the inner surface 32, which is also formed in the form of a thickened portion. When the sealing sleeve 1 is in the assembled state, the contact bead 41 presses against a surface of the cable.

[0090] The sleeve 1 is manufactured in one piece using a two-component injection molding process. The connecting membrane 30 is integrally formed with the base plate 10 of the sleeve 1. The inner ring 13 of the recess 12 thus provides a circumferential connection geometry 19 with a substantially L-shaped cross-section. The base plate 11 and the connecting membrane 30 are integrally connected to one another at this point.

[0091] To enable the sealing sleeve 1 to be installed close to a room edge, the base plate 10 is provided with a bent edge 15 extending in the connection plane 11. The bent edge 15 is formed in the manner of a film hinge by a local material recess on the underside 17 of the base plate 10 and is provided in the recess 12 at a distance from the inner edge 13. By providing the bent edge 15, the base plate 10 can be angled in a defined manner and positioned close to a room edge. The distance of a cable routed through the sleeve 1 to a wall or ceiling can thus be significantly reduced.

[0092] At two opposite ends of the folded edge 15, an outer edge 14 of the base plate 2 provides two notches 16. The notches 16 serve as centering aids for the cuff 1, simplifying the automation of handling processes during the manufacture, packaging, and / or assembly of the cuff 1. In particular, the notches 16 make it easier to give the cuff 1 a defined orientation. Furthermore, the notches 16 simplify gripping the cuff 1.

[0093] According to the first embodiment, the sealing sleeve 1 is designed symmetrically with respect to a plane of symmetry 3 extending perpendicular to the connection plane 11. The connection membrane 30 is designed symmetrically with respect to an axis of symmetry 2 extending in the plane of symmetry 2 of the sealing sleeve 1 and oriented perpendicular to the connection plane 11. Furthermore, the support webs 20, which are also regularly distributed in the circumferential direction 4, are arranged symmetrically with respect to the axis of symmetry 2 and the plane of symmetry 3.

[0094] The sealing sleeve 1 can, for example, be glued to the air-tight or diffusion-tight building envelope. For this purpose, an adhesive collar 56 can be provided on the sleeve 1. This is illustrated for the sleeve 1 shown in Figs. 1 to 4 using two examples.

[0095] In a first embodiment of the adhesive collar 56 according to Figs. 6 to 10, the adhesive collar 46 is glued to the upper side 18 of the base plate 10. The adhesive collar 56, which is ring-shaped and has a circular outer geometry, is also glued flatly to the air-tight or diffusion-tight building envelope (not shown). The adhesive collar 56 extends up to the area of ​​the interior space 13 of the base plate 10. It surrounds the frustoconical connecting membrane 30 in a ring-like manner.

[0096] Fig. 10 shows in detail the connection of the adhesive collar 56 to the base plate 10 of the sleeve 1. In addition, the L-shaped connection geometry 19 in cross section and the wave-shaped or S-shaped course of the support webs 20 in the connection area 22 of Fig. 10 can be clearly seen as a detailed enlarged representation.

[0097] Figs. 11 and 12 show the sealing sleeve 1 with the adhesive collar 56 in a second, alternative embodiment. The adhesive collar 56 is rectangular or square, respectively. In both embodiments discussed above, the adhesive collar 56 is glued to the top side 18 of the base plate 10. Alternatively, the adhesive collar 56 can be glued to the back side 17 of the base plate, according to a variant not shown.

[0098] A second embodiment of the sealing sleeve 1 is shown in Figs. 13 and 14. The sealing sleeve 1 has a connection membrane 30 extending in the connection plane 11 in the basic form shown.

[0099] As before, the total of eight support webs 20, regularly distributed in the circumferential direction 4, provide the wave-shaped or S-shaped connection area 22 with which they are connected to the base plate 10. The support webs 20, like the connection membrane 30, extend longitudinally in the connection plane 11. The length of the support webs 20 is determined such that they do not protrude into the annular disc-shaped contact collar 40 of the connection membrane 30, which also extends in the connection plane 11.

[0100] If, during installation and assembly, a line is passed through the line feedthrough opening 35 of the sealing sleeve 1, the contact collar 40 of the connection membrane rests against the jacket surface of the line. The contact collar 40 and optionally further parts of the connection membrane 40 and the support webs 20 can be pivoted out of the connection level 11, with the result that the connection membrane 30 loses its flat basic shape and, in an assembled state (not shown), takes on a truncated cone shape.

[0101] Further variants of the sealing sleeve 1 are shown in Figs. 15 to 18. The basic structure of the sealing sleeve 1 corresponds to that of the first embodiment according to Figs. 1 to 4. Modifications arise in particular with regard to the design of the connecting membrane 30 and the base plate 10. The respective different design features are discussed below without repeating the common features.

[0102] A third embodiment of the sealing sleeve 1 according to Fig. 15 omits the longitudinal thickenings 33 in the area of ​​the outer surface 32, which are located opposite the support webs 20 adjacent to the inner surface 31. Likewise, the annular thickening 34 on the outer surface 32 of the connecting membrane 30 is omitted.

[0103] A fourth embodiment of the sealing sleeve 1 shown in Fig. 16 differs from the third embodiment of the sealing sleeve 1 in the geometry or structure of the base plate 10. According to the fourth embodiment, the notches 16 on the base plate 10 are omitted, which serve as a centering aid in the automation of handling processes for the manufacture, packaging or assembly of the sleeve 1.

[0104] According to a fifth embodiment of the sleeve 1 according to Fig. 17, two circumferential annular thickenings 34 are formed on the outer surface 32 of the connecting sleeve 30 in addition to the longitudinal thickenings 33 and spaced apart from one another. The circumferential annular thickenings 34 are arranged concentrically to one another. They are spaced apart from one another at a constant distance.

[0105] The thickened portions 33, 34 together with the internal support webs 20 form a basket structure which gives the membrane 30 a high degree of resistance and robustness while maintaining its flexibility.

[0106] Fig. 18 shows a sixth embodiment of the sealing sleeve 1. In the sixth embodiment of the sealing sleeve 1, the two annular thickenings 34 are provided on the outer surface 32 of the connecting sleeve 30. In contrast, the longitudinal thickenings are omitted.

[0107] Referring to the first embodiment of the sealing sleeve 1 shown in Figs. 1 to 4, further variants of the sealing sleeve 1 are discussed below. The focus is on the new aspects and features, whereas known features and aspects of the respective variants are not described again.

[0108] 19 and 20 show a seventh embodiment of the cuff 1, in which a functional component 5 is integrated into the base plate 10. The functional component 5 can, for example, be a temperature, pressure or humidity sensor, which can serve in particular to detect a pressure drop or the ingress of moisture. For example, a data chip can be provided as the functional component 5. Manufacturing data or service life data of the cuff 1 can be stored on the data chip. For example, the functional component 5 can be designed as a transponder, which enables the location of the cuff 1 in the installed state. By providing the transponder as the functional component 5, it is particularly possible to locate a cuff behind a wall paneling and thus to enable very precise localization of the concealed cuff 1 during maintenance or repair work.

[0109] Figs. 21 and 22 show the sealing sleeve 1 in the first embodiment and, in addition, an additional disc 53, which is attached to the base plate 10 of the sleeve 1 via a plurality of clips 54 distributed in the circumferential direction and covers the sleeve 1 in the region of the underside 17. The additional disc 53 can serve, for example, as additional radiation protection for the shield. According to a first embodiment, the additional disc 35 provides a recess 55 arranged concentrically to the axis of symmetry 2 of the connection membrane 30 in the cable feedthrough opening 35, through which the cable to be installed can be passed.

[0110] Fig. 23 shows the sealing sleeve 1 with an alternative design of the additional disc 53. The additional disc 53 is secured to the base plate 10 of the sleeve 1 via clips 54 as usual. However, the recess is omitted. The additional disc 53 is thus completely closed at the factory. The recess can then be created on-site at the construction site. Optionally, a perforation or predetermined breaking point (not shown) can be provided on the additional disc 53 to create a feedthrough opening for the cable.

[0111] An eighth embodiment of the sealing sleeve 1 according to Figs. 24 and 25 dispenses with the factory-made feedthrough opening 35. Instead, the contact collar 40 encompasses a cable closure 36. The cable closure 36 is disc-shaped. A predetermined breaking point 37 surrounds the cable closure 36, which extends annularly and coaxially to the axis of symmetry 2 between the cable closure 36 and the contact collar 40. The provision of the predetermined breaking point 37 makes it possible, particularly on site, to remove the cable closure 36 during the passage of the cable through the sealing sleeve 1, thus creating the cable feedthrough opening during assembly.

[0112] Advantageously, by providing the line closure 36, a completely airtight or diffusion-tight sleeve 1 can initially be provided. Provided the sleeve 1 with the line closure 36 is properly installed and connected to the airtight or diffusion-tight building envelope, the airtight or diffusion-tight building envelope is airtight even if no line is routed through the sleeve 1.

[0113] Fig. 26 shows a variant of the eighth embodiment as the ninth embodiment of the sealing sleeve 1. Here, the line closure 36 has a tab 38 and an internal, not shown, annular predetermined breaking point. The tab 38 and the predetermined breaking point allow the line closure 36 to be removed without tools.

[0114] A tenth embodiment of the sealing sleeve 1 according to Figs. 27 and 28 provides that, to improve the sealing effect, a clamp 52 engages around the contact collar 40 on the outside and presses the contact collar 40 against a lateral surface of a pipeline 51. The clamp 52, as an additional component to be installed, thus improves the sealing effect. In addition, the contact collar 40 provides a contact bead 41. The contact bead 41 is formed as an external contact bead 41 on the outer lateral surface 32 of the connecting membrane 30.

[0115] Figures 29 and 30 show a sealing sleeve 1 in an eleventh embodiment. Here, a heating coil 7 with a plurality of heating loops is inserted into the

[0116] The base plate 10 of the sleeve 1 is incorporated. The heating coil 7 has electrical connection contacts. Energizing the heating coil 7 serves to firmly bond the sleeve 1 in the area of ​​the base plate 10 to the air-tight or diffusion-tight building envelope. Optionally, an adhesive collar (not shown) can be provided to connect the sealing sleeve 1 to the building envelope.

[0117] Figs. 31 to 33 show an assembly comprising a pipe closure 50 and the sealing sleeve 1 in the sixth embodiment. The sealing sleeve 1 is inserted into the end of the pipe closure 50, which can be mounted, for example, into the end of a KG pipe. The pipe closure 50 encompasses the base plate 10 of the sleeve 1 in the region of the outer edge 14. In particular, the pipe closure 50 is made of a plastic material and / or is connected to the base plate 10 of the sleeve 1 in an air-tight and / or diffusion-tight manner.

[0118] Fig. 34 shows a twelfth embodiment of the sealing sleeve 1. The sealing sleeve 1 provides a base plate 10 with a single recess 12. A connecting membrane 30 is inserted into the base plate 10, which has a double truncated cone shape and provides two spaced-apart cable feedthrough openings 35. The sealing sleeve 1 in the twelfth embodiment is thus designed as a double sealing sleeve 1. It allows two lines to be sealed simultaneously.

[0119] A thirteenth embodiment of the sealing sleeve 1 according to Fig. 35 is designed as a variant of the twelfth embodiment of the sealing sleeve 1. It provides that the connecting membrane 30, as a closed double connecting membrane, has two line closures 36. By providing the line closures 36, it is possible to connect the double sleeve 1 in an airtight manner to the building shell and then optionally pass no, one, or two lines through the sealing sleeve 1. In any case, the air- or diffusion-tight building envelope remains intact.

[0120] 36 and 37 show a 14th embodiment of the sealing sleeve 1. Here, the base plate 10 of the sealing sleeve 1 provides an induction wire 6. The induction wire 6 serves, similar to the heating coil 7 of the sealing sleeve 1 according to the eleventh embodiment, to heat the base plate 10 and to bond the sleeve 1 to the air-tight or diffusion-tight building envelope (not shown). Optionally, an adhesive collar can also be provided here. A 15th embodiment of the sealing sleeve 1 is shown in Figs. 38 and 39. The sealing sleeve 1 provides an injector connection piece 39 in the area of ​​the connection membrane 30. The injector connection piece serves to inject an injection medium, for example a hardening, self-expanding, swellable, self-sealing and / or permanently porous substance into the connection membrane 30 and thus achieve the sealing effect.The injector connection piece 39 forms a channel or passage. The connection membrane 30 is open in the area of ​​the injector connection piece 39 as well as in the area of ​​the line feedthrough opening 35. Airtightness or diffusion tightness is only achieved through the injected injection medium.

[0121] Figs. 40 and 41 show a 16th embodiment of the sealing sleeve 1. The 16th embodiment of the sealing sleeve 1 is a variant of the 15th embodiment of the sealing sleeve 1. In the 16th embodiment of the sealing sleeve 1, the injector connection piece 39 is closed. In order to inject the injection medium into the connection membrane 30, one end face of the injector connection piece 39 must be opened or pierced with an injector needle. The injector connection piece 39 is therefore also suitable for subsequently introducing the injection medium into the sealing sleeve 30, for example, during maintenance or repair of a connection membrane 30 that has become leaky.

[0122] While the adhesive collar 56 is described above as a possibility for creating an airtight connection between the sleeve 1 and the building envelope, this represents one of several solutions for creating this connection. Alternatively, for example, a collar enclosing the sleeve 1 can be ultrasonically welded to the base plate 10 of the sleeve 1 and / or the building envelope in an airtight manner. Mixed forms of the airtight connection are also conceivable. For example, the collar can be glued to the base plate 10 of the sleeve 1 and ultrasonically welded to the building envelope.
