The sealing assembly (30) extends in a longitudinal direction (16) between a first side (12) and a second side (14). The sealing assembly (30) comprises a sheathing tube (22) with an outer contour (24) that is at least partially corrugated, a compression ring seal (32), and a split annular flange (50). The sheathing tube (22) serves as an outer casing for at least one conduit (44, 46) that extends through the sheathing tube (22). The compression ring seal (32) is designed to seal the sheathing tube (22) against a surrounding building envelope (20). The split annular flange (50) has at least a first annular section (52; 352) and a second annular section (54; 354).At least the first ring section (52; 352) or the second ring section (54; 354) is displaceable between an out-of-engagement position and an engagement position with respect to a trough (26) of the corrugated outer contour (24) of the casing tube (22). In this way, the casing tube (22) is axially secured in the building envelope (20) in the engagement position when the compression ring seal (32) is activated.

Description

[0001] This disclosure relates to a sealing arrangement for the entry of pipes into buildings. Assemblies with such sealing arrangements can be referred to as building entry systems. In exemplary embodiments, this disclosure relates to measures for the axial securing of conduit in building entry systems, in particular to structural measures for pull-out protection in corrugated hoses or corrugated pipes installed with compression ring seals. Other areas of application are nevertheless conceivable.

[0002] Building entry points generally serve to bring utility and telecommunications lines into a building. This can include lines for drinking water, electricity, communication, heating, gas, and the like. Building entry points can pass through side walls (such as basement or ground floor walls) or through floors (such as the foundation slab in buildings without a basement). Building entry points must ensure the safe passage of lines without damage. Furthermore, adequate sealing of partition walls through which the building entry points pass is often required. Additionally, building entry points should provide a good seal against water and other environmental influences. For sealing, building entry points often utilize so-called annular seals or compression seals.These types of seals can be used to seal and fix pipes or cables lying in a wall or floor in their position.

[0003] General types of house entries are known, for example, from EP 0 987 482 A2, DE 10 2009 047 928 A1 and EP 0 976 880 B1.

[0004] Sealing arrangements with corrugated pipes are known from DE 20 2012 001 199 U1 and DE 10 2014 119 499 A1, wherein the corrugated pipes are sealed with a seal made of melt material. The sealing material must therefore be activated by suitable means, which increases the effort required for assembly. Such seals cannot be installed reversibly. Disassembly is difficult, and reassembly with the same sealing material may even be impossible.

[0005] From DE 198 14 982 A1 a sealing arrangement with a corrugated tube is known, which has a positive-locking seal in the form of a rubber sleeve at one end, wherein a welded adapter is arranged at the end opposite this, into which a knurled nut is screwed, and wherein a seal is arranged between the adapter and the knurled nut.

[0006] A corrugated pipe or hose is a pipe made of rigid material (plastics, metals, or similar) with a corrugated shape and varying diameter. Due to this design, corrugated pipes offer a degree of flexibility, allowing them to be adapted to specific structural conditions. Corrugated pipes can be used, for example, to protect or isolate one or more internal pipes and conduits. They can be made from materials such as polyvinyl chloride (PVC), polyethylene (PE), and other plastics. Corrugated pipes made of metal alloys are also known.

[0007] Corrugated pipes are flexible within certain limits, allowing for good adaptability to existing bores and penetrations. However, this advantage is regularly accompanied by reduced stiffness / stability. This must be taken into account when considering axial position retention (pull-out protection). Position retention using fusible material and similar methods is not only more complex to install, but also more complex to remove. Reusing the corrugated pipe or the sealing material itself is generally impossible.

[0008] Against this background, the present disclosure aims to provide a sealing arrangement for the introduction of pipes into buildings, which utilizes a sheathing tube with an outer contour that is at least partially corrugated, wherein the sheathing tube can be firmly and securely positioned in its installation position by suitable structural measures. Furthermore, reliable positioning is to be provided using simple means. In particular, the installation of the sheathing tube and the sealing arrangement as a whole is to be simplified. The use of consumables that are difficult to process (melt material as sealing material and for positioning) is to be reduced or completely avoided. Finally, simple disassembly and, at least in some cases, reuse / re-use of the sheathing tube and the seal are to be enabled.

[0009] According to a first aspect, the present disclosure relates to a sealing arrangement for introducing pipes into buildings, wherein the sealing arrangement extends in a longitudinal direction between a first side, in particular a building side, and a second side, in particular an environment side, and comprises the following: - a sheathing tube with an outer contour that is at least partially corrugated, serving as an outer casing for at least one conduit extending through the sheathing tube, - a compression ring seal designed to seal the casing pipe against a surrounding building envelope, - a split ring flange having at least a first ring section and a second ring section, wherein at least the first ring section or the second ring section is displaceable between an out-of-engagement position and an engagement position with respect to a wave valley of the corrugated outer contour of the casing pipe, so that the casing pipe is axially secured in the building envelope in the engagement position when the compression ring seal is activated.

[0010] The objective of the disclosure is thus fully achieved. According to the disclosure, a simple mechanical axial positional locking mechanism for the sheathing pipe can be provided. In this way, corrugated pipes and similar pipes can be positioned and fixed securely, reliably, and with high pull-out forces. For example, if the sealing assembly is installed as part of a building entry point in the building envelope, the axial positional locking mechanism of the sheathing pipe as disclosed can be achieved.

[0011] The outer casing can be designed entirely or partially as a corrugated tube and, when viewed in a longitudinal section, may feature ridges (peaks) and depressions (valleys). The outer casing is made, for example, of metals or plastics.

[0012] The ring flange is designed in multiple parts or segments. The design with two or more ring sections allows for a positive-locking axial positioning of the casing tube. At least one of the ring sections can be recessed into a corrugation to axially secure the casing tube. This corrugation can also be described as a constriction on the circumference of the casing tube.

[0013] The ring flange with its two or more ring sections is shown as an example on the first side, i.e., the interior of the building. This is not to be understood as a limitation. The ring flange can also be described as a split securing flange for the casing pipe.

[0014] The longitudinal direction is usually straight (linear). However, designs with a curved longitudinal extension and consequently a curved longitudinal direction are also conceivable. Corrugated pipe casings can be flexible within certain limits, allowing for adjustment of the sealing arrangement to non-perfectly linear wall / floor penetrations. In principle, deflections are also conceivable, such as 90° deflections between the first and second sides.

[0015] The compression ring seal is, for example, a radially outer seal that sits on the outer circumference of the casing pipe and is supported with its outer circumference within the opening (borehole or the like) of the building envelope (wall, floor or the like).

[0016] When the compression ring seal is activated, its outer circumference is forced outwards and its inner circumference inwards. In this way, the compression ring seal ensures a good seal between the outer building envelope and the inner casing pipe. The compression ring seal is typically activated by axial clamping, for example, by moving two opposing pressure discs, between which the sealing element of the compression ring seal is positioned, towards each other, causing the sealing element to move radially outwards and radially inwards.

[0017] In the engaged position of the ring flange, axial forces acting on the casing pipe can be transferred into the building envelope via the ring flange or its ring sections. The casing pipe cannot be easily moved axially relative to the sealing element. Axial forces are, for example, transferred at least partially into the building envelope via the ring flange and / or the sealing element.

[0018] With the house entry fully assembled, overall higher axial holding forces result. This provides better security for the conduit itself, as well as the entire house entry system.

[0019] Thermally or otherwise activated position locking mechanisms are unnecessary. The mechanical position locking allows for easy assembly and disassembly. This can also include the reusability of the components involved. Therefore, the seal can be designed to be highly reversible (reusable).

[0020] The sealing element of the (radially outer) compression ring seal does not necessarily have to be adapted to the specific design of the outer tube. In other words, a corrugated tube can be sealed with a sealing element that, at least in its unloaded (non-activated) state, is smooth on its (e.g., cylindrical) inner surface. This allows suitable sealing elements to be used with different outer tube designs or corrugation contours in corrugated tubes.

[0021] The disclosed sealing arrangement allows for a certain degree of stress relief on the sealing body of the compression ring seal. The sealing body can potentially be compressed less strongly (radially) than in conventional solutions because the axial retention function is partially performed by the ring sections, which in turn can be axially coupled to the sealing body. Reduced deformation of the sealing body results in lower stress on the casing tube in the area of ​​the sealing body.

[0022] The partially form-fitting axial positioning of the casing prevents unwanted movement of the casing, thereby relieving stress on any sealing elements that act against the casing. This effectively contributes to preventing creep effects in elastomers and similar materials used as sealing agents. The sealing elements retain their favorable properties over a longer period.

[0023] For example, a compression ring seal with a coupled, split ring flange can be installed on each of the two sides of the sealing assembly, the ring sections of which are displaceable relative to the casing tube between the out-of-engagement and engagement positions. In such a case, high axial holding forces result regardless of the direction of pull.

[0024] Positioning is primarily secured axially by one or more ring sections of the sealing assembly. The sealing element acts primarily radially on the outer circumference of the casing tube. In this way, the stability of the casing tube is maintained even in the area of ​​the corrugated outer contour.

[0025] The disclosed sealing arrangement can be used for various applications, including building technology, pipeline construction (for example, for plant engineering), and the laying of supply lines. In general, lines can be fastened and secured quickly and reliably.

[0026] The disclosed sealing arrangement is suitable for both horizontal and vertical installation. In a vertical installation, the weight of the pipes themselves also acts on the sealing arrangement, which can result in high pull-out forces. Nevertheless, the sealing arrangement allows for a permanently secure installation.

[0027] The defined mobility of the ring sections allows for easy and quick assembly and disassembly of the sealing assembly, thereby reducing maintenance and repair efforts. Furthermore, it provides a visual indicator of the assembly's installation status. It is easily discernible whether the ring sections are engaged or disengaged from the casing tube.

[0028] Due to their flexibility, the ring sections of the split ring flange are tolerant of diameter variations and / or shape deviations in the casing. Secure axial positioning is still ensured. Furthermore, the assembly principle allows the sealing assembly to be placed in relatively confined and difficult-to-access areas. The movement of the ring sections from the disengaged to the engaged position can be easily accomplished with the compression ring seal relieved of tension. The compression ring seal can then be tightened in the usual manner, automatically securing the engaged position of the ring sections.

[0029] According to an exemplary embodiment, the first and second ring sections are displaceable in a plane perpendicular to the longitudinal direction. This plane is, for example, parallel to the wall or floor surface. The ring section(s) can be moved linearly, pivoted, or moved in a combined motion within this plane between the engaged and disengaged positions. In this way, at least one ring section can laterally engage a trough in the casing tube to axially secure it in its position. This allows for a sealing arrangement with minimal axial space requirements, as at least one ring section does not necessarily need to be moved axially.

[0030] According to a further exemplary embodiment, both the first ring section and the second ring section are each displaceable between the out-of-engagement position and the engagement position, wherein the first ring section and the second ring section are in particular movable towards and away from each other in order to be displaced between the out-of-engagement position and the engagement position.

[0031] This includes, for example, a movement of the ring segments relative to a common center (e.g., the longitudinal axis through the sealing arrangement). In the disengaged position, the ring segments, or at least segments thereof, are further away from the common center than in the engaged position.

[0032] A design of the ring flange that is at least two parts ensures, on the one hand, a large (comprehensive) overlap in the engagement position, and on the other hand, engagement takes place along a large part of the circumference of the sheathing tube, i.e., for example, over more than 300° of the circumference, preferably over more than 330° of the circumference.

[0033] According to a further exemplary embodiment, the split ring flange has three or more ring sections, two or more of which are displaceable between the out-of-engagement position and the engagement position, preferably each ring section being displaceable between the out-of-engagement position and the engagement position.

[0034] If three or more ring sections are provided, they can be moved towards and away from each other relative to a common center, similar to a jaw chuck. In this way, engagement can be achieved over a large circumferential area.

[0035] In an exemplary embodiment, the split ring flange has exactly two identically designed ring sections which, at least in the engagement position, are arranged offset from each other by about 180° (degrees) and complement each other to 360° or nearly 360°.

[0036] In an exemplary embodiment, the split ring flange has exactly three identically designed ring sections, which are arranged at least in the engagement position offset from each other by about 120° and complement each other to 360° or almost 360°.

[0037] According to another exemplary embodiment, the at least one movable ring section between the out-of-engagement position and the engaged position can be pivoted about a pivot axis or displaced along a straight or curved path. This results in a defined and reproducible movement between the out-of-engagement position and the engaged position.

[0038] According to a further exemplary embodiment, the at least one movable ring section has at least two holes for fastening elements, wherein a movement path of the at least one movable ring section for the movement between the out-of-engage position and the engaged position is defined by a design of the holes.

[0039] For example, each of the at least two ring sections has two or three holes (e.g., screw holes), in particular four or five screw holes. At least some of the holes are not necessarily circular, but are designed as elongated holes with a linear or curved principal direction of extension. In this way, a guide can be provided for the movement of the ring section relative to fasteners that protrude through the holes. The fasteners are fixed in position with respect to the center, so that the ring section is moved relative to the center in this way.

[0040] The fasteners protrude through the holes. These fasteners are an example of a component of the compression ring seal and serve to activate / tension the sealing element.

[0041] According to another exemplary embodiment, the at least two holes of the at least one movable ring section define a path of movement for a sliding motion. In this embodiment, elongated holes with a linear or curved main direction of extension are used. The holes are oriented parallel to each other or arranged in a parallel pattern. In this way, a guide for the sliding motion is created.

[0042] According to another exemplary embodiment, the at least two holes of the at least one movable ring section define a path of movement for a pivoting motion. In this way, a defined movement of the ring section with respect to the center is achieved for switching between the engaged and disengaged positions.

[0043] According to another exemplary embodiment, a first hole defines a pivot bearing for a pivot axis, wherein at least a second hole spaced apart from this defines a pivot angle for a pivoting movement about the pivot axis.

[0044] The first hole then serves, for example, as a pivot point for the swiveling movement. Accordingly, the first hole does not need to be designed as an elongated hole or the like. The first hole is, for example, located at one end (in the circumferential direction) of the ring section. The ring section can then be swivelled, like a wing or lever, at least by a small angle, to switch between the engaged and disengaged positions.

[0045] According to another exemplary embodiment, in addition to the first and second holes, at least a third hole for fastening elements is provided in the ring section, the dimensions of the second and third holes being adapted to their distance from the first hole and the given pivot angle. The further the second hole, third hole, and any further holes are spaced from the first hole (pivot point), the longer the respective (e.g., curved) slot extension must be.

[0046] In exemplary embodiments, the radius of curvature of the second and third holes is adapted to their respective distances from the first hole. In particular, the radius of curvature corresponds to the respective distance from the first hole (pivot point).

[0047] It goes without saying that, in principle, a combination of a swiveling movement and a linear movement (superimposed movement) is also possible if the backdrop defined by the holes is designed accordingly.

[0048] According to another exemplary embodiment, the fastening elements are clamping elements for a compression ring seal that connects axially to the ring flange. In this way, existing fastening elements can be used as part of the guide track for the movement of the ring section. The fastening elements protrude through the holes.

[0049] The compression ring seal is, for example, a radially outer seal between the casing pipe and the surrounding building envelope. In the axial direction, the compression ring seal is usually arranged inside the bore or penetration, for example flush or almost flush with an end face of the bore / penetration.

[0050] Using components of the compression ring seal as part of the guide for the movement of at least one movable ring section reduces the number of parts required for the additional functionality (axial position locking). When the fasteners are tightened to activate / pre-tension the compression ring seal, the current position (engagement position) of the ring flange or the at least one movable ring section can simultaneously be fixed and secured. When the compression ring seal is tensioned, the ring flange is also securely tightened.

[0051] In another exemplary embodiment, the ring flange with its ring sections sits on an outer pressure plate of the compression ring seal. This positions the ring sections just outside the bore or opening. The ring sections face both the pressure plate and the surrounding surface of the building envelope. In this way, the ring flange contributes to the axial positioning of the radially outer compression ring seal relative to the building envelope.

[0052] In one exemplary embodiment, the ring flange contacts a wall surface / floor surface of the building envelope and simultaneously axially contacts the pressure disc of the compression ring seal.

[0053] According to another exemplary embodiment, the casing tube can be axially mounted in the out-of-engage position of the at least one movable ring section. In other words, the ring flange as a whole can provide a clearance through which the casing tube can be inserted.

[0054] According to another exemplary embodiment, the casing tube can be axially removed when the at least one movable ring section is in the disengaged position. At least in exemplary applications, the casing tube can be removed non-destructively. This also includes non-destructive removal of the elements for axial position securing.

[0055] According to another exemplary embodiment, the casing tube can be reversibly disassembled axially in the out-of-engage position of the at least one movable ring section. In other words, the components for the axial positioning of the ring flange can be reassembled and restored to a functional state after disassembly according to this embodiment.

[0056] According to another exemplary embodiment, an assembly aid is arranged on the at least one movable ring section, which, in the disengaged position, prevents flush mounting of a cover. The cover can also be referred to as an end cap.

[0057] The cover, for example, carries a radial inner compression ring seal, which is positioned inside the conduit to seal one or more pipes extending longitudinally through the conduit. For instance, the radial outer compression ring seal and the radial inner compression ring seal overlap axially, so that in the overlap area, the radial outer compression ring seal acts on the circumference of the conduit from the outside and the radial inner compression ring seal from the inside. During installation, the cover is placed onto the ring flange when the inner radial compression ring seal is inserted into an interior space within the conduit. Together, the inner radial compression ring seal and the outer radial compression ring seal ensure a hermetic seal at the conduit entry point. It is understood that corresponding compression ring seals can be installed on either side (inside and outside) of the conduit entry point.

[0058] The assembly aid is designed to prevent incorrect assembly of the ring sections or the sealing assembly as a whole. This is achieved by the fact that, in the disengaged position of at least one movable ring section, the assembly aid collides with part of the cover, preventing the cover from being flush with the ring flange. When the movable ring section(s) are in the engaged position, the assembly aid is also positioned so that the cover can be flush with the ring flange. This significantly reduces the risk of incorrect assembly. It ensures that the axial locking mechanism is activated when the building entry is completed by placing the cover with the radially inner compression ring seal. In other words, the ability to fit the cover serves as an indicator of correct assembly with the ring sections in the engaged position.

[0059] According to another exemplary embodiment, the assembly aid is designed as a tongue, in particular as an integral component of the at least one movable ring section with a partially axial and partially radial extension. When using sheet metal parts, the tongue can be easily produced by forming (bending).

[0060] In one exemplary embodiment, the tongue is designed as a tab extending from a base body of the ring section towards the lid. In another exemplary embodiment, the tab is oriented towards the center of the sealing assembly. Thus, the tab and the base body are not necessarily oriented at right angles (90°) to each other. Instead, in exemplary embodiments, the tab is inclined slightly inwards, resulting in an angle of approximately 80°, 70°, and 60° between the tab and the base body. This makes the assembly aid more tolerant of (minor) positional deviations in the lid.

[0061] According to a further aspect, the present disclosure relates to a building entry with a sealing arrangement according to at least one of the embodiments described herein. The building entry can have several (radially inner and radially outer) compression ring seals, for example on the first side and on the second side. At least one of the compression ring seals is part of a sealing arrangement according to the disclosure with axial position retention for the casing pipe.

[0062] It is understood that the features of the disclosure mentioned above and those to be explained below can be used not only in the combinations specified, but also in other combinations or on their own, without leaving the scope of the present disclosure.

[0063] Further features and advantages will become apparent from the following description of several exemplary embodiments with reference to the drawings. These show: Fig. 1: A perspective view of a house entry with a sealing arrangement, from the first side, showing a partial section of a building envelope in which the house entry is embedded; Fig. 2: another perspective, partially cropped view of the house entrance according to Fig. 1, where the section extends through further components; Fig. 3: an enlarged partial representation based on the representation according to Fig. 2 to illustrate an engagement position of a ring section for axially securing the position of a sheath tube; Fig. 4: a frontal view of an end face of an embodiment of a sealing arrangement with two ring sections in a disengaged position in which a sheath tube is released; Fig. 5: one opposite Fig. 4. Modified design of a sealing arrangement; Fig. 6: another one on Fig. 4 based view, showing one ring section in an out-of-engagement position and another ring section in an engagement position; Fig. 7: a schematic, simplified end-face view of a further embodiment of a sealing arrangement with three ring sections in an engaged position to secure a sheathing tube; and Fig. 8: Another view based on Fig. 7, wherein the three ring sections are in an out-of-engage position to release a sheath tube.

[0064] Fig. Figure 1 illustrates, using a perspective view, an exemplary design of a building entry, designated as 10. The building entry 10 extends between a first side 12 and a second side 14. The first side 12 typically faces the interior of the building. The second side 14 typically faces the surrounding area. The building entry 10 extends along a (global) longitudinal direction 16.

[0065] The building entry point 10 serves for the defined routing of pipes and cables through building envelopes, such as walls, floors, or the like. This can include, for example, supply lines. Building entry points 10 can also be used for routing pipes for heat pumps and similar equipment. Building entry points 10 and corresponding sealing assemblies can also be installed between two technically separate rooms or building sections.

[0066] The service entry 10 protrudes through an opening or borehole in a building envelope 20. The building envelope 20 can be, for example, a wall or a floor of a building. The building envelope 20 is in Fig. 1 shown only in part and partially cropped. In the supplementary illustration according to Fig. 2. Further components of the house entry 10 are shown partially cut away. In the Fig. 1 and Fig. The two end components of the house entry 10 are not shown in their final assembled position on page 12 for illustrative purposes. This is explained in more detail below.

[0067] The house entry 10 has a sheathing duct 22 extending in the longitudinal direction 16, which is provided at least partially or completely with a corrugated outer contour 24. In the on Fig. 2 based on enlarged partial representation according to Fig. Figure 3 shows a trough of the outer contour 24 with 26. The sheathing tube 22 can also be referred to as a corrugated tube. The sheathing tube 22 can be made of plastic (thermoplastic materials, possibly with reinforcement), metal materials, or other suitable materials. The sheathing tube 22 sits with its outer contour 24 inside the building envelope 20. An annular space 28 extends between the sheathing tube 22 and the building envelope 20, see Figure 3. Fig. 2. Further components of the house entry 10 may be installed within the sheathing tube 22.

[0068] The house entry 10 has at least one sealing arrangement 30 with a compression ring seal 32. In the exemplary embodiment according to the Fig. 1 and Fig. 2. The compression ring seal 32 is a radially outer compression ring seal on the first side 12. In the exemplary embodiment, the house entry 10 has a further compression ring seal 38, which is arranged as a radially outer compression ring seal on the second side 14. Furthermore, a further compression ring seal 40 is provided (in the Fig. 1 and Fig. 2 shown in the uninstalled state), which is provided as a radial inner compression ring seal on the first side 12.

[0069] One or more lines 44, 46, which are designed, for example, as media lines (water, gas, and the like), energy lines (electricity supply), other connection lines (fiber optic, telephone, cable connection, and the like), or the like, extend through an interior space 42 of the casing 22. The house entry 10 according to the Fig. 1 and Fig. 2 is designed as a so-called multi-utility service entry. However, this should not be interpreted as a limitation.

[0070] In the exemplary embodiment, the compression ring seals 32, 38 seal the outer casing 22 radially outwards (in the bore or penetration) against the building envelope 20. The compression ring seal 40 seals the lines 44, 46 in the interior 42 of the outer casing 22 against the outer casing 22. This results in a hermetic seal. Additional seals may be installed, for example, on the second side 14.

[0071] The sealing arrangement 30 further comprises a split ring flange 50, which is coupled to the compression ring seal 32 at its end face. In the exemplary embodiment, the compression ring seal 32 is arranged within the building envelope 20. The split ring flange 50 is located, for example, on a wall surface or floor surface of the building envelope 20.

[0072] In the exemplary embodiment, the ring flange 50 has a first ring section 52 and a second ring section 54. Together, the two ring sections 52 and 54 form the ring flange 50. In the exemplary embodiment, each of the two ring sections 52 and 54 extends approximately 180° around the circumference of the casing tube 22; together, the two ring sections 52 and 54 extend approximately 360° around the circumference of the casing tube 22. The ring sections 52 and 54 each have several holes 60 and fastening elements 62 protruding through them. In particular, the fastening elements 62 are simultaneously clamping elements of the compression ring seal 32. The holes 60 are at least partially designed as elongated holes with curved extension, so that an overall guide track for movement of the ring sections 52, 54 between an engagement position and an out-of-engagement position is created with respect to the casing tube 22.The fastening elements 62 are, for example, screws.

[0073] Fig. Figure 3 shows an enlarged partial representation based on Fig. Figure 2 illustrates an engagement state (engagement position) of the ring section 52. In the engagement state, the ring section 52 is at least partially engaged in a trough 26 on the outer contour 24 of the casing tube 22. This provides axial positional security for the casing tube 22 against undesired axial movements in the longitudinal direction 16.

[0074] In the engaged position, the ring sections 52, 54 are close to the casing tube 22. In the disengaged position, the ring sections 52, 54 are at least partially spaced somewhat further away from the casing tube 22 and, in particular, are disengaged from the trough 26. The movement of the ring sections 52, 54 between the engaged and disengaged positions is enabled and guided by a guide cam formed jointly by the holes 60 and the fastening elements 62. When the fastening elements 62 are tightened in the engaged position of the ring sections 52, 54, this position of the ring sections 52, 54, and thus the axial positioning of the casing tube 22, is fixed.

[0075] In the Fig. 1 and Fig. Figure 2 further shows 68 assembly aids for the ring sections 52, 54. The assembly aids 68 are exemplified as tongues 70 extending from a base body of the ring sections 52, 54 away from the compression ring seal 32. In an exemplary embodiment, the tongues 70 are inclined at 90° relative to the base body of the ring sections 52, 54. In the embodiment according to the Fig. 1 and Fig. 2. The tongues 70 are inclined at 60° to 80° relative to the base body of the ring sections 52, 54. In this way, the tongues 70 in the radial seal can cover a minimum area (radial extent) despite the comparatively thin material thickness.

[0076] The tongues 70 are an aid to prevent incorrect assembly. When the ring sections 52, 54 are in the disengaged position (out-of-engagement position) with respect to the casing 22, i.e., when the axial position lock is not activated, the tongues 70, due to their position, prevent the installation of the radially inner compression ring seal 40 and its associated end cap. In the retracted position (engagement position), the tongues 70 no longer obstruct the assembly, and the house entry 10 can be completed.

[0077] Fig. Figure 2 shows that the compression ring seal 32 in the exemplary embodiment has an outer pressure disc 74, a sealing element 76, and an inner pressure disc 78. The sealing element 76 is located between the two pressure discs 74 and 78. The pressure discs 74 and 78 can be pre-tensioned by means of clamping elements (compare the fastening elements 62) and moved towards each other. In this way, the sealing element 76 is axially compressed, followed by radial displacement (outwards towards the building envelope 20 and inwards towards the casing tube 22).

[0078] Similarly, the compression ring seal 38 on the second side 14 also has an outer pressure disc 82, an inner pressure disc 86 and a sealing element 84 arranged in between, which can be pressed together with clamping elements (screws and the like) if required.

[0079] Similarly, the compression ring seal 40 has an outer pressure washer 90, a sealing element 92, and an inner pressure washer 94. The pressure washers 90 and 94 can be moved towards each other by clamping elements 102 (for example, screw-type fasteners) to compress the sealing element 92. Disassembly involves releasing the pressure on the sealing elements 76, 84, and 92 by opening the pressure washers 74, 78; 82, 86; 90, and 94.

[0080] In the exemplary embodiment according to Fig. In the outer pressure plate 90, the outer pressure plate is part of a cover 98 or coupled to the cover 98. The cover 98 can also be referred to as the end cap at the first side 12 of the house entry 10. In the exemplary embodiment, the cover 98 has a rim 100, in particular a circumferential rim 100, which faces the compression ring seal 32. In the assembled state, the radially inner compression ring seal 40 sits in the interior 42 of the casing 22, and the cover 98 at least partially or completely covers the ring sections 52, 54. However, this is only possible if the ring sections 52, 54 are in the engagement position in which the axial position locking for the casing 22 is available. Then the rim 100 does not collide with the mounting aid 68. If at least one of the ring sections 52, 54 were in the out-of-engage position, the associated mounting aid 68 would collide with the rim 100, so that the cover 98 cannot be mounted flush.

[0081] In Fig. 2 is indicated by 108 as a plane (for example, wall surface or floor surface) in which the ring sections 52, 54 can be moved to bring about the transition between the engagement position and the out-of-engage position.

[0082] Finally, curved double arrows illustrate 112, 114 in Fig. 3 the pivoting movement of the ring sections 52, 54 between engagement position (compare Fig. 3) and the non-intervention position (compare Fig. 5).

[0083] Based on the Fig. 1-3 are based on the Fig. 4-6 exemplary embodiments of the sealing arrangement 30 are illustrated. Fig. Figures 4-6 each show a frontal end view of the ring flange 50 with the two ring sections 52, 54. Fig. 4 and Fig. The ring sections 52 and 54 are each in the out-of-engage position. In this position, the sheathing tube 22 can be moved longitudinally (perpendicular to the plane of view). Fig. 4 and Fig. 5) be moved axially. The representation in Fig. Figure 6 shows the ring section 52 in the engaged position and the opposite ring section 54 in the disengaged position, which in Fig. The dashed section of ring segment 52 is in a wave trough 26 (compare Fig. 3) of the casing tube 22 is indented. The ring sections 52, 54 can be positioned in this indented position according to the Fig. 4-6 each assume the engagement position. The possible movement of ring sections 52, 54 in the Fig. 4-6 is indicated by curved double arrows 112, 114.

[0084] The movement of ring sections 52, 54 according to the Fig. 4-6 each represent a pivoting movement about a pivot axis 120, which is jointly defined by a fastening element 62 and a first hole 122. In the exemplary embodiment, the first hole is followed by second holes 124, third holes 126, fourth holes 128, and fifth holes 130. The greater the distance of the holes 124, 126, 128, 130 from the pivot point according to the first hole 122, the greater the longitudinal extent of the holes 124, 126, 128, 130 must be. In the exemplary embodiment, the holes 124, 126, 128, 130 are designed as curved elongated holes. The first hole 122 is typically a circular hole. The curvature of the holes 124, 126, 128, 130 is adapted to the respective distance from the first hole 122. For example, the respective radius of curvature corresponds to the distance of holes 124, 126, 128, 130 from the first hole 122.

[0085] In the exemplary embodiment according to Fig. 4. The two ring sections 52, 54 are mirror-symmetric with respect to a longitudinal median plane (vertical plane in Fig. 4) designed. Accordingly, the two pivot axes 120 and the respective first holes 122 are also adjacent to each other. In the exemplary embodiment according to Fig. In section 5, the two ring sections 52 and 54 are arranged offset from each other by 180° with respect to a common center. Furthermore, the Fig. 4-6 a frontal view of the mounting aids 68, which are moved outwards or inwards when the ring sections 52, 54 are moved in relation to the center in the interior 42 of the sheathing tube 22.

[0086] The arrangement of ring sections 52, 54 in Fig. 6 is based on that of Fig. 4. It is understood that, contrary to the representation chosen for illustrative purposes in Fig. 6. Usually, both ring sections 52, 54 should be in the engagement position or the non-engagement position together.

[0087] A movement path for the two ring sections 52, 54 is jointly defined by the fastening elements 62 and the holes 122, 124, 126, 128, 130 (generally: holes 60). The fastening elements 62 are simultaneously clamping elements for the compression ring seal 32, see Figure 1. Fig. 1 and Fig. 2.

[0088] In addition to the Fig. Figures 4-6 illustrate the Fig. 7 and Fig. Figure 8 shows a schematic frontal view of a ring flange 250, which can also be used with the sealing arrangement 30. The ring flange 250 has three ring sections 252, 254, 256, which in the exemplary embodiment each extend approximately 120° around the circumference of the sheathing tube 22 and together complete 360° or nearly 360°.

[0089] In the exemplary embodiment, the ring sections 252, 254, 256 are each provided with holes 260 in the form of elongated holes with a straight extension. Fastening elements extend through the holes 260 (in the Fig. 7 and Fig. 8 not shown). The holes 260 are not radially aligned, but parallel to a desired radial sliding movement, compare arrows 272, 274, 276 in Fig. 8. Ring sections 252, 254, 256 can be designed identically.

[0090] Fig. Figure 7 shows an inset state (engagement position) of the ring sections 252, 254, 256 in relation to the casing tube 22. An overlap area is indicated by a dashed line. Fig. Figure 8 shows a disengaged state (out-of-engagement position) of the ring sections 252, 254, 256, in which the casing tube 22 is radially released, so that axial movement of the casing tube 22 in the longitudinal direction (perpendicular to the plane of view) is possible.

[0091] Based on the Fig. Based on the principles illustrated in 4-8, other designs of split ring flanges with ring sections movable between the out-of-engage position and the engagement position can be derived, which can be used for axial position securing in the casing tube 22.
