Description

[0001] The invention relates to a sealing module for a sealing arrangement for sealing one or more pipes against an opening in a wall area, wherein the sealing module has a housing that can be positioned around a section of the pipe, wherein a sealing material for sealing against the pipe is arranged in the housing, the diameter of which lies between a smallest pipe diameter and a largest pipe diameter, and wherein the sealing material is permanently elastic or permanently plastic, and wherein the sealing material has a recess for the pipe, the free cross-section of which has smaller dimensions than the smallest pipe diameter.Furthermore, the invention also relates to a sealing arrangement for sealing a pipe against an opening in a wall area, wherein the sealing arrangement has an outer sealing section for sealing against the opening and an inner sealing section for sealing against the pipe.

[0002] According to the invention, a conduit is understood to be, for example, electrical conduits or conduits carrying media, such as gas or water pipes. It is generally known how such conduits are to be laid through one or more wall sections of a building. A sealing module is optionally arranged around the conduit to create a seal against it. The purpose of this seal is, in particular, to hinder, or ideally prevent, the passage of moisture or gases into the building along the surface of the conduit.

[0003] Sealing assemblies of the type described above, which are frequently components of building entry points or wall penetrations, have a housing that can be positioned around a section of the pipe or conduit and consist of two housing parts movable relative to each other. The housing includes a receiving chamber in which a sealing element is arranged for sealing against the pipe or conduit passing through the opening in the wall. The invention relates in particular to sealing assemblies in the form of sealing inserts and sealing assemblies with frames for enclosing several sealing modules. Sealing inserts are understood here to be inserts with a substantially cylindrical circumferential surface that are inserted into corresponding core bores in walls and comprise one or more sealing modules.

[0004] WO 99 / 56368 A1 discloses a modular cable entry system comprising a plurality of modules, each providing at least one passage for a cable. The sealing module has two module parts that are placed around the cable, creating a seal. Inside each module part is a sealing element made of an elastic material, which is brought into contact with the cables held between the module parts. The module parts are each tailored to the dimensions of the cable to be accommodated by the cable entry system. Cables with different dimensions therefore require modules specifically adapted or tailored to their dimensions, meaning that a large number of different modules must be kept in stock.

[0005] WO 2010 / 090588 A1 shows a passage for a cable or pipe in the form of a sealing module with two mutually movable base parts, which have a number of superimposed layers of a rubber material in the direction of the pipe or pipe to be sealed. Depending on the diameter of the pipe or pipe to be sealed, the corresponding number of layers are removed, similar to peeling an onion, but starting from the inside. Each layer offers only a very narrow tolerance range for the diameter of the pipe or pipe to be sealed. To ensure a reliable seal against the pipe or pipe surface, the base parts and the layers are clamped together, and an additional sliding and sealing material is used to reliably prevent the ingress of, for example, moisture through the sealing module.

[0006] Mounting such a sealing module around a pipe is very labor-intensive and therefore time-consuming.

[0007] Furthermore, DE 299 11 305 U1 and DE 20 2006 017 659 U1 each disclose a cable gland comprising a sealing element and housing parts surrounding the sealing element. The housing parts have inwardly projecting edges by means of which the sealing element is positioned between the housing parts or sealed externally against the housing parts.

[0008] US 2010 / 0001476A1 relates to a sealing device for sealing cables and pipes against wall sections, with at least one outer sealing section for sealing against a penetration in a wall section.

[0009] The object of the present invention was therefore to provide a sealing module for a sealing arrangement, as well as such a sealing arrangement, by means of which the disadvantages described above are overcome as far as possible. In particular, the object was to ensure a reliable seal for pipes with different diameters while simultaneously ensuring ease of handling.

[0010] The invention solves the underlying problem in a sealing module of the type described above by providing the housing with at least two spaced-apart lips on the inside as retainers for the permanently elastic or permanently plastic sealing material, wherein the lips are made of a flexible material and are dimensioned such that a clear width between the lips for the conduit corresponds at least to the largest diameter of the conduit to be accommodated by the sealing module.

[0011] The invention is based on the finding that the use of a permanently elastic or permanently plastic sealing material in the housing ensures a flexible seal such that pipes with diameters differing from one another by up to 10 mm, preferably up to 20 mm, can be sealed on the outside of the pipe using the same sealing material designed according to the invention. Preferably, a single sealing material is therefore sufficient for sealing pipes with a diameter preferably in the range of 15 to 35 mm. Preferably, the sealing material has a recess for the pipe, the free cross-section of which is smaller than the cross-section of the smallest pipe to be sealed over it. This ensures a sufficiently high surface pressure of the sealing material against the surface of the smallest pipe intended for this purpose.

[0012] In one embodiment of the invention, the permanently elastic or permanently plastic sealing material is preferably a material that retains its shape in the housing under appropriate support and without the application of force. However, a permanently plastic material is dimensionally unstable under sufficiently high pressure and preferably deforms upon contact with the pipe to be sealed. A permanently plastic sealing material that has already been used does not return to its original shape after the force acting upon it is removed. In contrast, a permanently elastic sealing material is preferably dimensionally stable and returns to its original shape after the force acting upon it is removed. For example, a foam material is used as a permanently elastic sealing material, and butyl rubber is used as a permanently plastic sealing material.

[0013] The lips that retain the sealing material are preferably dimensioned such that the clear width between the lips for the conduit is at least equal to the largest diameter of the conduit to be accommodated by the sealing module. The clear width of the recess between the sealing material positioned in the housing between the lips is smaller than the smallest conduit diameter to be accommodated by the sealing module. In one embodiment of the invention, the sealing material projects radially inwards beyond the lips that preferably retain the sealing material laterally.

[0014] In a preferred embodiment of the invention, the housing is formed from several housing parts that are movable relative to each other. The sealing module, together with the sealing material, forms a kind of cuff around the pipe, wherein the sealing material preferably has a cylindrical recess for the pipe to be sealed and cylindrical or cuboid outer dimensions.

[0015] Preferably, the sealing material is formed from several, preferably hemispherical, segments, each segment being received in a corresponding housing part of the sealing module according to the invention. Due to the design of the sealing material as hemispherical segments, it can be brought into contact with the outside of the pipe by simply placing it against or around the pipe's outer surface. Preferably, the segments, as well as the housing parts of the sealing module that receive the segments of the sealing material, are symmetrically designed.

[0016] In another preferred embodiment, the permanently elastic sealing material is an activatable mass or swellable material which expands in volume upon contact with a fluid and achieves the desired sealing effect through swelling.

[0017] Preferably, sealing materials with different degrees of hardness are used. This allows the sealing module to be adjusted with respect to its flexibility in compensating for differences in the diameter of the pipes to be sealed. In a preferred embodiment, sealing materials with different degrees of hardness are color-coded, thus facilitating easy identification of the hardness of the different sealing materials.

[0018] A further development of the sealing module according to the invention provides that the lips are elastically deformable. This allows the lips to react to changes in the shape of the sealing material when pressure is applied, preferably deflecting in the axial direction. This increases the sealing effect of the sealing material against the pipe without excessively forcing the sealing material out of the receiving space in the housing. In a preferred embodiment, the clear width between the lips for the pipe accommodated between them is dimensioned to correspond approximately to the smallest pipe diameter that the sealing module can accommodate. Preferably, the lips are formed integrally with the housing parts of the sealing module; in particular, the lips extending radially inwards are injection-molded onto the housing parts.In a preferred embodiment, the lips do not run parallel, but obliquely to each other, with the distance between the lips widening in a wedge shape from the base of the housing part in the direction of the dividing plane of the two housing parts that can be placed against each other.

[0019] Preferably, the housing comprises a tube body with outwardly directed projections on each end face to aid positioning. The sealing material is held in a predetermined orientation around the pipe to be sealed via the tube body. The tube body, extending along a section around the pipe, preferably forms a fixed counter-bearing for the sealing material, which is made of a flowable and / or activatable sealing material. Preferably, outwardly directed projections are arranged on or in the region of the end faces of the tube body. These projections, in conjunction with a sealing arrangement that accommodates the sealing module, serve as a positioning aid for the sealing module to seal a pipe against an opening in a wall area.Preferably, the sealing module is positioned and locked in the axial direction on the sealing assembly via the outwardly projecting protrusions. In a preferred embodiment, the tube body is cylindrical or rectangular.

[0020] Preferably, the pipe body is made of a dimensionally stable material or of a material with variable diameter and soft elastic properties. The dimensionally stable material decouples the sealing effect of the sealing module against the pipe from the sealing effect of the sealing arrangement housing the sealing module against the opening in the wall. The sealing effect is then primarily determined by the degree of compression exerted by the permanently elastic or permanently plastic sealing material surrounding the pipe, which is held in contact with the pipe by the housing of the sealing module.

[0021] In an alternative preferred embodiment, a soft-elastic material is used to form the pipe body, which yields under externally applied clamping force, causing the pipe body to deform. This allows an additional force component to be applied externally to the sealing material when the housing is closed and clamped, thereby preferably increasing the sealing effect between the sealing material and the outer diameter of the pipe to be sealed. With a sealing material that can be activated by a compressive force, simple and effective activation of the sealing material is achieved via the deformable pipe body. A material exhibiting soft-elastic properties could, for example, be a plastic that is deformable when a corresponding force is applied.

[0022] According to a further development of the sealing module according to the invention, a substantially radially inwardly directed projection is arranged axially spaced from the lip, wherein a collection area for sealing material that has escaped from the receiving chamber is formed between the projection, which is preferably arranged at the end face, and the lip. The collection area ensures that any flowable sealing material that has escaped from the receiving chamber is collected within the area of ​​the sealing module. This prevents potential contamination of the surrounding area. In addition, the installer can quickly verify, by visual inspection of the sealing material collecting in the collection area, that the pipe is sufficiently clamped and sealed by the housing. The collection area is preferably formed in the form of an annular groove between the radially inwardly projecting projection and the lip, which is arranged substantially parallel to the projection.

[0023] According to a further development of the invention, the housing parts are movably connected to each other via a hinge. The hinge ensures that the two housing parts of the sealing module are always correctly aligned or positioned relative to each other. Furthermore, it simplifies the installation of the sealing module around the pipe to be sealed. The housing parts of the sealing module, together with the segments of sealing material arranged in the receiving spaces of the housing parts, can be folded or pivoted relative to each other and placed around the pipe in a cuff-like manner.

[0024] In a further preferred embodiment of the invention, the hinge is designed as a film hinge, which allows for a manufacturing-efficient connection of the two housing parts that are held movable relative to each other. Instead of a hinge connecting the two housing parts, positioning elements, for example positioning pins, can also be provided on the housing parts projecting towards the other housing part. These engage in corresponding receptacles on the other housing part.

[0025] In another aspect, the invention relates to a housing for a sealing module for sealing against a pipe according to one of the preferred embodiments described above, with an inner receiving space for a sealing material that can be positioned around the pipe and which is permanently elastic or permanently plastic, wherein at least two lips spaced apart from each other are arranged inside the housing as retainers for the sealing material.

[0026] Furthermore, the invention relates in another aspect to a sealing material for a sealing module for sealing against a pipe according to one of the preferred embodiments described above, which is arranged to be received by a housing with an inner receiving space and positioned around the pipe, and to be held back by at least two lips arranged at a distance from each other in the receiving space, wherein the sealing material that can be brought into contact with the pipe is permanently elastic or permanently plastic, and wherein the sealing material has a recess as a passage for the pipe, the free cross-section of which has smaller dimensions than the cross-section of the smallest pipe to be sealed over it.

[0027] In a further aspect, the invention relates to a kit consisting of a housing according to one of the preferred embodiments described above, and several sealing materials according to one of the preferred embodiments described above, wherein the sealing materials define a set of sealing materials, the different sealing materials of a set having different degrees of hardness and / or different sized recesses for the pipes to be accommodated. Thus, the sealing module has a certain degree of adjustability with regard to its flexibility to compensate for differences in the diameter of the pipes to be accommodated by means of the sealing material. In a preferred embodiment, each sealing material of a set of sealing materials has a corresponding color according to its degree of hardness, thereby enabling simple identification of the hardness of the different sealing materials.Preferably, a one- or multi-component material with permanently elastic or permanently plastic behavior is used as the sealing material. For example, butyl rubber is used as a permanently plastic sealing material, which can be used together with reactive components. Preferably, the surface of the butyl rubber sealing material facing the pipe is equipped with a nonwoven fabric that, after activation of the sealing material, is penetrated by it and comes into contact with the pipe surface.

[0028] In a preferred embodiment, each sealing material in a set of sealing materials is partially or completely colored according to its hardness, thus enabling easy identification of the hardness of the different sealing materials. Preferably, a one- or multi-component material with permanently elastic or permanently plastic behavior is used as the sealing material. For example, butyl rubber, which can be used in conjunction with reactive components, is employed as the sealing material.

[0029] According to a further aspect, the invention relates to a sealing arrangement for sealing a pipe against an opening in a wall area, comprising an outer sealing section for sealing against the opening and an inner sealing section for sealing against the pipe.

[0030] The invention, with reference to the problem mentioned above concerning the sealing module, also solves the problem with regard to a sealing arrangement by designing the inner sealing section provided in the sealing arrangement as a sealing module according to one of the preferred embodiments described above. A sealing arrangement with a sealing module according to the invention can be mounted relatively easily around pipes with differing pipe diameters without the need to adapt the sealing material of the sealing module according to the invention to the pipe diameter or to use a sealing material precisely matched to the diameter of the pipe section and additional sealing material.The permanently elastic or permanently plastic sealing material used exhibits such elasticity or plasticity that, within a predetermined diameter range of the pipe to be accommodated, regardless of its exact diameter, the sealing material can simply be brought into contact with or applied to its outer circumferential surface. The sealing module is preferably accommodated by the sealing arrangement in such a way that a continuous sealing effect is ensured from the inner wall surface of the opening in the wall area to the outside of the pipe.

[0031] Preferably, the outer and inner sealing sections are configured to seal independently of each other against the opening in the wall area and the pipe passing through the sealing module. This allows the sealing effect against the pipe and against the wall area in the opening to be adjusted independently and thus individually. However, in one embodiment of the invention, the sealing module is designed such that when the sealing effect is generated at the outer sealing section, at least the sealing effect at the inner sealing section is further increased.

[0032] In a preferred embodiment of the invention, the outer sealing section consists of an elastically compressible material and has at least one recess for receiving the sealing module according to the invention. After the sealing module has been positioned around the pipe, it is inserted into the recess of the outer sealing section, and then the pipe, together with the sealing arrangement according to the invention, is positioned within an opening in a wall area. To prevent unintentional displacement or removal of the sealing module within or from the outer sealing section, the projections, which extend substantially radially outwards on the sealing module, overlap material areas of the outer sealing section, thus at least hindering axial displacement within the outer sealing section. The recess in the outer sealing section is preferably matched to the outer diameter of the pipe body of the sealing module.

[0033] Preferably, the outer sealing section has several recesses for sealing modules that can be inserted therein, one, several, or all of which are arranged off-center on a partial circle diameter around the center point of the outer sealing section. With such an outer sealing section, several sealing modules can thus be simultaneously and several lines can be guided together through an opening in a wall area. Preferably, the multiple recesses are arranged on a common partial circle diameter around the center point of the outer sealing section. In one embodiment of the invention, in addition to the off-center recesses in the outer sealing section, a recess extending coaxially to the center point of the outer sealing section can be formed. The recesses can have a uniform or different diameters.

[0034] Preferably, a clamping device for clamping the outer sealing section is associated with the outer sealing section. The outer sealing section, which is made in particular of an elastically compressible material, is clamped, preferably compressed, over a predetermined area by means of the clamping device. This results in the outer sealing section expanding or extending essentially perpendicular to the compression direction of the clamping device. Due to the expansion, preferably in a radial direction, areas of the outer sealing section preferably fully conform to the wall surface of the opening in the wall area and to the outer circumference of the sealing module received in the recess on the outer sealing section. Depending on the material used to form the housing of the sealing module, e.g.,Made of an elastically deformable and therefore compliant material, the clamping of the outer sealing section leads to an additional increase in the sealing effect of the sealing material in the sealing module according to the invention with respect to the pipe passing through the sealing module. If the housing of the sealing module is made of a dimensionally stable material, its housing parts are compressed by the clamping of the outer sealing section until they touch each other. No additional clamping of the sealing material contained in the housing then occurs.

[0035] In a preferred embodiment, the clamping device comprises two clamping elements whose distance from each other is variable in the longitudinal direction of the pipe. The two clamping elements of the clamping device are preferably also varied in their axial distance from each other, whereby the associated areas of the outer sealing section are also axially compressed, and thus the outer sealing section expands or elongates substantially perpendicular to this compression. Preferably, the clamping elements of the clamping device are designed as ring bodies which are axially connected to each other by several clamping elements designed as screws.

[0036] In a preferred embodiment of the invention, the outer sealing section of the sealing arrangement is a frame that can be inserted into the opening of the wall area and accommodates one or more sealing modules that can be positioned side by side and one above the other in a predetermined arrangement. The frame preferably extends over the entire length of the opening in the wall area and overlaps, preferably on both sides, the end faces of the wall area that defines the opening. Preferably, the frame has a rectangular shape, with one or more sealing modules arranged in the free cross-section of the frame.

[0037] In one embodiment of the invention, the sealing modules are sealed against each other and against the inside of the sealing arrangement with frame inserted into the opening in the wall area with a separate sealing agent.

[0038] The invention is described in more detail below with reference to several exemplary embodiments and the accompanying figures. These figures show: Fig. 1 and Fig. 2: a perspective view of a sealing module according to a first embodiment; Fig. 3: A perspective view of a sealing arrangement according to a first embodiment, with several sealing modules according to the Fig. 1 and Fig. 2 Fig. Figures 4 to 6: a perspective view of a sealing module according to the invention in a second embodiment; Fig. 7: A perspective view of a sealing arrangement according to a second embodiment with multiple sealing modules according to the Fig. 4 to 6, and Fig. 8: A perspective view of a sealing arrangement according to a third embodiment with multiple sealing modules according to Fig. 4 to 6.

[0039] The Fig. 1 and Fig. Figure 2 shows a first embodiment of a sealing module 1 for sealing against a pipe, comprising a housing 4 that can be positioned around a section of the pipe and consists of two housing parts 6, 6' that are movable relative to each other. Within the housing 4, a receiving chamber 8 is formed for a sealing material 10 that can be brought into direct contact with the pipe. The sealing material arranged in the receiving chamber is permanently elastic or permanently plastic and is designed for sealing against pipes with different diameters. The sealing material used to form the sealing material 10 is deformable to such an extent that pipes with diameters differing from each other by up to 20 mm can be sealed with the same sealing material 10 designed according to the invention. Furthermore, each housing part 6, 6' has two lips 12, 12' that laterally delimit the receiving chamber 8 and retain the flowable sealing material within the receiving chamber 8.

[0040] Furthermore, how from Fig. As can be seen in Figure 2, the sealing material 10 has a recess 14 as a passage for the conduit, the free cross-section of which is smaller than the cross-section of the smallest conduit to be sealed. The sealing material is also segmented or segment-like. In the illustrated embodiment, the sealing material 10 extends axially within the receiving space 8 in the housing over a region between 70% and 90% of the total length of the sealing module 1 according to the invention. In a kit consisting of a housing and several sealing materials, these form a set of sealing materials, wherein the different sealing materials of a set are formed from sealing materials with different degrees of hardness. In one embodiment, the lips 12, 12' that laterally enclose the sealing material 10 in the axial direction are formed from a flexible material.These lips can deflect axially when pressure is applied to the sealing material by means of the pipe connected to it. In the illustrated embodiment, the lips 12, 12' run obliquely towards each other, their distance widening wedge-shaped from the base of the housing part towards the parting line of the two housing parts 6, 6'.

[0041] In the illustrated embodiment, the housing 4 of the sealing module 1 has a cylindrical tube body 16 made of a dimensionally stable material or a material with elastic properties that vary in diameter. The tube body 16 has an outwardly directed projection 18 on each end face as a positioning aid, by means of which, as will be explained in more detail later, the sealing module is secured to the sealing arrangement. Furthermore, an inwardly extending projection 20 is arranged on the tube body 16, wherein a collection area 22 for sealing material that has escaped from the receiving chamber 8 is formed between the projection 20 and the lip 12, 12' located adjacent to the projection, which is preferably formed integrally with the tube body 16. Fig. 1 and Fig. 2 further illustrate that the housing parts 6, 6' are movably coupled to each other via a film hinge 24.

[0042] In Fig. Figure 3 shows a perspective view of a sealing arrangement 40, which is designed in the form of a sealing insert, has an outer sealing section 42 for sealing against an opening (not shown) in a wall area, and an inner sealing section 44 designed as a sealing module 1 for sealing against a pipe (not shown). A clamping device 46 is associated with the outer sealing section 42, which has two clamping elements 48, 48' designed as ring bodies and connected to each other by clamping means 50. The clamping means 50 change, in particular reduce, the axial distance between the clamping elements 48 of the clamping device 46, so that the outer sealing section 42 arranged between the clamping device 46 is compressed in the axial direction.Simultaneously, the outer sealing section expands radially, so that the outer sealing surface 52 of the outer sealing section 42 is brought into sealing contact with a wall surface of the opening (not shown) in a wall area. Furthermore, the radially expanding outer sealing section 42 seals against the sealing modules 1 arranged in several recesses of the outer sealing section. The outer sealing section forms a sealing contact with the outer circumferential surface of the cylindrically shaped pipe body 16 of the sealing module 1. The sealing modules 1 are connected via the projection 18 extending outwards from the pipe body 16, as shown in the figure. Fig. 3, visible, locked in the axial direction in the outer sealing section 42.

[0043] Fig. Figures 4 to 6 show an alternative embodiment of a sealing module 1' with a housing 4' formed from two housing parts 26, 26'. In contrast to sealing module 1, sealing module 1' has a substantially rectangular tube body 16'. Within the receiving space 8' is a sealing material 10' ( Fig. 5) arranged to have a hollow cylindrical shape. The sealing material 10' is formed from two half-shells which define a recess 14 for the pipe to be sealed. The recess 14' has a free cross-section whose dimensions are smaller than the cross-section of the smallest pipe to be sealed above it. The receiving space 8' for the sealing material 10', bounded by the housing parts 26, 26', also has two lips 28, 28' that define the receiving space in the axial direction and by means of which the sealing material of the sealing material 10' is at least partially prevented from protruding from the receiving space 8'. In the illustrated embodiment, the clear width between the lips 28, 28' for the pipe received therein is dimensioned such that it corresponds approximately to the smallest pipe diameter to be received by the sealing module. In the illustrated embodiment, a sealing plug 2 is arranged within the recess 14'.

[0044] In Fig. Figure 7 shows a perspective view of a sealing arrangement 40' according to a further embodiment, which is also designed as a sealing insert and has an outer sealing section 42' for sealing against an opening (not shown) in a wall area with a rectangular passage 43. Several sealing modules 1' are arranged within the passage 43, with which the inner sealing sections 44' are formed on the sealing arrangement 40' for sealing against the pipes extending through the sealing arrangement 40'. In the embodiment shown, the sealing plugs 2 are depicted in place of the pipes to be sealed in the passages. In an embodiment not shown, the sealing modules 1' each have an outwardly directed projection on both end faces of the pipe body 16' as a positioning aid relative to the outer sealing section 42'.The protrusions allow the sealing modules 1' to be fixed axially to the sealing assembly.

[0045] The outer sealing section 42' is similar to the sealing arrangement 40 made of Fig. 3, a clamping device 46' is assigned, which has several clamping bodies 54, 54' designed as plate bodies and connected to each other via clamping means 50. The axial distance between the clamping bodies 54, 54' of the clamping device 46' is changed, in particular reduced, by means of the clamping means 50. An outer sealing section 42' arranged between the clamping device 46' is compressed in the axial direction. At the same time, the outer sealing section 42' expands radially outwards and inwards, so that the outer sealing surface 52' of the outer sealing section 42' is brought into sealing contact with a wall surface of the opening (not shown) in a wall area. In addition, the radially expanding outer sealing section 42' seals against the sealing module 1' arranged in several recesses of the outer sealing section.The outer sealing section forms a sealing contact with the outer circumferential surface of the rectangular pipe body 16' of the sealing module 1.

[0046] Fig. Figure 8 shows a further embodiment of a sealing arrangement 60, which has a rectangular frame 62 as an outer sealing section that can be brought into sealing contact with an opening in a wall area not shown in detail. In an embodiment not shown, the frame 62 has outerly circumferential legs that extend beyond the wall area at its ends.
