PIPE PENETRATION THROUGH A BUILDING DIVIDER

Description

[0001] To ensure the long-term functionality of buildings, whether residential, social, industrial, or similar, a protective building envelope is essential. Particular attention must be paid to fluid-tight, and especially airtight, gas-tight, building waterproofing, particularly at building components in contact with the ground, generally referred to as the "basement." In addition to surface waterproofing, such as moisture-resistant coatings on exterior walls and the foundation slab, almost every project includes point penetrations through the waterproofing, such as pipes. These pipes, for example, carry wastewater from the basement of a house to a sewer system.Such penetrations through the building's waterproofing naturally represent weak points and are also very prone to errors in practice.

[0002] To route a pipe, especially a wastewater pipe, through a basement wall or building foundation slab, it is necessary to install an additional pipe section, specifically a pipe stub, which must have a sealing or connection flange for the building waterproofing. The truly watertight and moisture-tight integration of the connection flange with the building waterproofing is particularly important.

[0003] The wastewater pipe is pushed into or through this pipe stub, and a watertight connection between the pipe stub and the wastewater pipe is created using a so-called annular seal. At this interface between the building waterproofing specialist and the plumber, errors frequently occur, ultimately leading to moisture damage in a building.

[0004] It should be emphasized at this point that the penetrations through structural separation elements discussed above are by no means limited to water / wastewater lines. Such pipe stubs – naturally secured with suitable sealing elements against the inner wall of the pipe stub, for example based on Polopas – can also accommodate electrical, data, air conditioning, and gas lines.

[0005] It is frequently observed that, particularly for economic reasons, a pipe stub as described above is not installed, and a direct sealing connection to the outer circumference of the wastewater pipe is made. Experience has shown that this is particularly prone to damage.

[0006] From EP 2273170 A1, a formwork insert for wall penetrations is known, comprising at least one pipe which has a first and a second end, wherein it is closed at its first end and at its second end by a closing plate which has a larger diameter at least in one fastening area than the pipe at its first end and at its second end.

[0007] In CH 522091 a wastewater drain nozzle for watertight installation in base plates, walls and ceilings made of waterproof concrete is described, which is equipped with a sealing sleeve cast into the concrete and directed radially outwards.

[0008] From EP 3361132 A1 a pipe penetration through a building ceiling or basement wall is known with a pipe stub which has a flange to be applied flat to the outer surface of the component.

[0009] EP 1462706 A1 describes a feedthrough pipe with several sealing fins and flange plates abutting the two outer surfaces of a component.

[0010] From DE 4427603 C1, a construction separating element for indoor and outdoor use is known, which is provided on at least one side with a full-surface coating of a sealing material and which has a pipe penetration for cables that fully penetrates the separating element transversely. The separating element further comprises a sealing and stabilizing lamella surrounded by the material of the separating element and a sealing flange that is integrated into the hazardous area of ​​the separating element.

[0011] German patent DE 3231932 A1 discloses a pipe socket for a roof drain. The pipe socket has a flange that is flush with the upper surface of the roof and is designed as a double-flange unit.

[0012] From DE 102005030470 A1, a mounting frame for use in a wall penetration is known, comprising a pipe for insertion into the wall penetration and an annular flange attached to one end of the pipe. The circumference of one end of the pipe carries a sealing material and the end is enclosed by the annular flange.

[0013] From EP 2273170 A1, a formwork insert for a wall penetration is known, comprising a pipe whose two ends are closed by a sealing plate. The pipe of the formwork insert can be fitted with connecting elements, for example with a socket and a cage.

[0014] A further known method involves a wall penetration through concrete walls in which a bituminous thick coating is bonded to the vulnerable side of a building element. This is achieved by mechanically fixing the bituminous material of the coating to the outer sealing flange of a pipe to be embedded in concrete. This is accomplished by roughening the outer surface of the sealing flange or by applying a fabric, thus creating a purely mechanical bond of the bituminous coating. The sealing flange can also be provided with several undercut grooves, specifically with a dovetail cross-section, to achieve a mechanical interlocking of the building coating with the flange.

[0015] The present invention relates to a building, in particular a structural, partition element according to claim 9 for indoor and outdoor use, comprising the group consisting of masonry, wall, ceiling, damp-proof or basement ceiling, foundation slab or part thereof, particularly based on concrete, which is provided at least on one side with a full-surface coating of a sealing material resistant to the penetration of fluid media such as moisture, water, gases and air, with at least one pipe penetration integrated into the partition element, fully penetrating transversely, for lines such as electrical, data, air conditioning and gas lines, in particular for water and wastewater, into which partition element at least one pipe section according to the invention, fully penetrating transversely, is embedded or integrated. wherein the stabilizing lamella is embedded in the material, in particular concrete, of the separating element, and wherein the sealing flange is embedded or integrated in the vulnerable area, wherein according to the invention it is provided that the pipe section is equipped with the sealing flange at its pipe connection socket, that - forming a double flange unit - the sealing flange is fully connected over its outer surface to a coating connection flange, which projects beyond it on all sides and preferably uniformly laterally, made of a material identical or highly compatible with the coating sealing material, preferably bitumen, optionally reinforced with adhesive, and that the double flange unit fits precisely into a recess shaped according to its geometric form.A recess is located in the hazardous area of ​​the separating element, wherein the outer surface of the coating connection flange of the double flange unit is aligned with the hazardous area of ​​the separating element, preferably exactly, and the sealing coating applied to the hazardous area is seamlessly or jointlessly, preferably steplessly and at the same level, and with full-surface material bonding to the outer surface of the coating connection flange, to the connection flange with which it is materially identical, and forms a single unit with it.

[0016] By using two pipe sections or pipe stubs according to the invention inserted in the component according to the invention, the structural, in particular structural, separating element according to claim 10 is formed with only minor adjustments, which is characterized in that that it is equipped for the implementation of twin pipelines having pipes guided at a standardized distance from one another with the twin pipeline section according to the invention, with two pipe stubs arranged parallel to each other and at a distance from one another, but with the common, materially uniform, essentially spectacle-shaped twin sealing flange at their two pipe connection sockets, that the stabilizing lamella is embedded in the material, in particular concrete, of the separating element, that - forming a twin double flange unit - the twin sealing flange is fully connected over its outer surface to a twin coating connection flange, also approximately spectacle-shaped, which projects beyond it on all sides and optionally uniformly, laterally, and made of a material identical to or highly compatible with the coating sealing material, preferably bitumen, optionally reinforced with adhesive,that the twin double flange unit fits precisely into a recess or indentation in the hazard area of ​​the separating element, shaped according to its geometric form, , wherein the outer surface of the twin coating connection flange of the twin double flange unit is aligned with the hazard surface of the separating element, preferably exactly, and that the sealing coating applied to the hazardous area connects seamlessly, preferably steplessly and at the same height or level, and with full-surface material bonding to the outer surface of the twin coating connection flange, and thus to the twin coating connection flange with which it is materially identical, forming a single unit.

[0017] The invention provides a separating element for construction which, despite the use of extremely different components, such as a plastic feedthrough pipe and a separating element made of a mineral building material, in particular concrete or dense concrete, and despite their different orientations or positioning, such as vertical and horizontal or vice versa, is practically a single unit.

[0018] The use of the new, virtually one-piece building partition element makes it possible, especially in buildings, to achieve a kind of "bulkhead" construction, i.e., a "bulkhead-by-bulkhead" sealing of individual building areas such as floors and rooms, as is particularly known from shipbuilding.

[0019] A key component of the invention is a pipe stub, including a pipe socket, whose length is adapted to the thickness of the basement or damp-proof room wall, ceiling, or foundation slab. A sealing flange is located in a recess in the structural divider at the outer edge of the pipe socket for a push-fit connection with another pipe. The coating connection flange, which projects beyond the flange on all sides, is fully bonded to this flange on its upper surface. Together with the coating connection flange, the sealing flange forms the double-flange unit, the outer surface of which is flush with the exposed surface of the structural divider. The fluid-medium-proof, and in particular moisture-proof, coating of the exposed surface of the structural divider is applied integrally to this outer surface, while keeping the opening of the pipe socket clear.

[0020] The material of the coating connection flange is advantageously the same as that of the hazardous area sealing coating.

[0021] In the next step, the installer only needs to connect a wastewater sewer pipe to the pipe socket on the inside of the basement, for example, and insert another wastewater sewer pipe into the pipe socket on the outside of the basement.

[0022] These work steps complete the highly secure, watertight integration of, in particular, wastewater sewer pipes into the building waterproofing, i.e., especially into the building separation element.

[0023] The advantage of this innovative wastewater sewer pipe, including pipe socket and connection flange, is that an additional pipe stub including the annular seal is eliminated, thus significantly reducing potential weak points of the pipe penetration.

[0024] An essential component of the construction separation element according to the invention is the fluid-medium-tight pipe penetration through the element itself, i.e., the pipe section according to the invention, in particular pipe stub, for the installation of at least one pipe penetration, in particular water or wastewater pipe penetration, into or through a construction separation element, in particular a building separation element, as described in more detail above, which is provided with a sealing material coating applied over its entire surface exposed to the elements. which pipe section is manufactured in one piece from a plastic material and is formed with a pipe socket facing the hazardous area with an annular sealing groove for a watertight and moisture-tight connection of a downstream pipe, and with at least one stabilizing lamella extending transversely outwards to the pipe stub axis and an annular, in particular circular, sealing flange abutting the hazardous area, wherein - forming a double flange unit - the sealing flange is fully connected over its outer surface to a flat, also annular, in particular circular, coating connection flange, in particular reinforced with adhesive, which also projects laterally over the circumference of the same, and wherein the double flange unit can be inserted precisely into a recess shaped according to its geometric form in the hazardous area of ​​the structural separation part.

[0025] A twin pipe section according to the invention, as described in claim 2, which is intended for use in construction, in particular in building construction, and which is slightly varied compared to the single pipe stub described above, and which has two parallel, spaced-apart pipe stubs for the installation of two pipe penetrations, for example water or wastewater and cable penetrations, in or in the building structure, and which is intended for use in construction, in particular in building structures, according to claim 10.by a structural, in particular structural, separating element, in particular made of concrete, which is provided with a sealing material coating applied over its entire surface of the hazard area, which twin pipe section is manufactured in one piece from a plastic material, wherein the pipe stubs are each formed with a pipe socket facing the hazard area with an annular sealing groove for a fluid medium-tight, in particular water- and moisture-tight, connection of two further (off) supply pipes, and at least one stabilizing lamella extending transversely outwards to the pipe stub axis and a common, material-identical twin sealing flange abutting the hazard area, essentially spectacle-shaped, preferably oval, and in that it is characterized, . that it is equipped for the implementation of twin pipelines having pipes guided at a standardized distance from one another with the twin pipeline section according to the invention, with two pipe stubs arranged parallel to each other and at a distance from one another, but with the common, materially uniform, essentially spectacle-shaped twin sealing flange at their two pipe connection sockets, that the stabilizing lamella is embedded in the material, in particular concrete, of the separating element, that - forming a twin double flange unit - the twin sealing flange is fully connected over its outer surface to a twin coating connection flange, also approximately spectacle-shaped, which projects beyond it on all sides and optionally uniformly, laterally, and made of a material identical to or highly compatible with the coating sealing material, preferably bitumen, optionally reinforced with adhesive,that the twin double flange unit fits precisely into a recess or indentation in the hazard area of ​​the separating element, shaped according to its geometric form, , wherein the outer surface of the twin coating connection flange of the twin double flange unit is aligned with the hazard surface of the separating element, preferably exactly, and that the sealing coating applied to the hazardous area connects seamlessly, preferably steplessly and at the same height or level, and with full-surface material bonding to the outer surface of the twin coating connection flange, and thus to the twin coating connection flange with which it is materially identical, forming a single unit.

[0026] The essential difference between the pipe stub used according to the invention and the previously mentioned, known pipe section lies in the fact that the latter attempts to achieve a bond between the sealing flange and the coating material by purely mechanical means, i.e., by altering the bonding surface of the sealing flange by roughening its outer surface by applying a fabric to it or by incorporating grooves with undercuts.

[0027] According to the invention, however, a particularly high bond of this kind is achieved through the chemical material identity between the coating connection flange of the double flange unit, which protrudes on all sides, and the coating compound.

[0028] For a practically unlimited time-independent sealing of the novel pipe penetration, it is particularly advantageous if the pipe section or twin pipe section cast into and encased in concrete in the building, in particular the structural separating element, is made of a heat-resistant, impact-resistant, preferably reinforced plastic material that is resistant to the material of the separating element, in particular concrete, on the one hand, and to the coating sealing material and the material of the coating connection flange or twin coating connection flange on the other.

[0029] In particular, for the proper positioning of the double flange unit under the airtight, gas-proof, water-proof and moisture-resistant, full-surface coating of the separating element, i.e. the hazardous area of ​​the building separating element, it is important to install a pipe section whose coating connection flange, but preferably the double flange unit, is designed in an annular shape with at least two or twice two opposing, in particular straight, segment-like flat sections in the outer circumference.

[0030] In the case of a twin pipeline section according to the invention, it is provided that that - forming a twin double flange unit - a twin coating connection flange, projecting laterally on all sides beyond the twin sealing flange, is fully connected over its upper or outer surface, being essentially spectacle-like, preferably oval, flat, and in particular adhesively reinforced, wherein the twin double flange unit can be inserted into a recess shaped according to its geometric form in the hazard area of ​​the building separating part, and wherein the stabilizing lamellae of each of the two pipe stubs are positioned at a distance from each other.

[0031] Particularly for the tight connection of the respective coating connection flange to the pipe socket(s), it is advantageous if the pipe section or the twin pipe section is characterized by the fact that the pipe connection socket(s) is or are formed with an edge ring projecting above the level of the sealing flange or twin sealing flange, preferably at a height corresponding to or equal to the thickness or height of the coating connection flange or twin coating connection flange fully connected to it, and the coating connection flange or the twin coating connection flange is fully bonded to the outer wall of this edge ring with its inner wall.

[0032] For both a secure hold in the tightly enclosing building partition element and for particularly secure moisture protection, a pipe section or twin pipe section according to the invention is advantageous, which is characterized in that the stabilizing lamella(s) is or are aligned over a flat surface with an undercut at an angle of less than 90° to its axis.

[0033] With regard to uncomplicated connection to an inlet pipe system from inside the building and an outlet pipe system to the outside, e.g. for connection to a sewer system, a pipe section or twin pipe section is advantageous if its pipe stub has a total length essentially corresponding to the thickness of the building separation element by whose material it is fully embedded, and if it or its pipe stub is designed to be open at the socket end with a chamfer towards the building separation element opposite the hazardous area, preferably parallel to it.

[0034] Last but not least, a coating connection flange for forming a double flange unit with the sealing flange of a pipe section, in particular a pipe stub, should be mentioned, which is characterized in that it is made of a material identical or highly compatible with the material of the coating on the one hand for a jointless or seamless and level, material-integral, full-surface connection to the, in particular material connection with the fluid-medium-resistant sealing coating of the hazardous area of ​​a building, in particular a building, separation element on the one hand and for a full-surface connection with the sealing flange, and is designed as a ring flat on both sides, in particular a circular ring, with a circular opening having an opening radius corresponding to the outer radius of the rim ring.

[0035] The invention will be explained in more detail below with reference to the drawing: The drawing shows the Fig. 1 a sectional view of a structural separation element according to the invention, equipped with the new pipe section, in particular a pipe stub, for example a basement wall, which Fig. 2 a top view of the double flange unit or of the coating connection flange of the pipe section penetrating the structural separating element, which Fig. 3 the sectional view of a structural separation element penetrated by a twin pipeline section and the Fig. 4 the twin pipeline section itself.

[0036] The Fig. 1 The following is shown: A pipe section formed with a pipe stub 5, enabling the pipe passage for water or wastewater through a building separation element 1, such as an outer wall of a basement adjacent to the moist soil of a building site, is fully embedded in the building material, in particular concrete, i.e., material Mt.

[0037] The pipe stub 5 is essentially formed with a standard cylindrical pipe section 50, which widens towards the hazardous area 12 of the separating element 1 – usually an outer surface of a basement wall – which is endangered by moisture or water directly, for example in the soil of the building site and its entry and passage, and towards a standard water / wastewater pipe socket 55 with an internal sealing groove 54 for a sealing ring for connecting a standard water / wastewater discharge pipe, for example to a sewer.

[0038] Approximately in the middle, the pipe stub 5 has a stabilizing lamella 51 extending perpendicularly to the pipe stub axis A into the concrete, which in particular ensures a stable hold in the concrete mass Mt of the structure-separation 1, i.e. e.g. the outer wall of a building.

[0039] The pipe stub 5 has a rim ring 522 with a height h which is equal to the thickness h' of the connecting flange 15. The total length I5 of the pipe stub 5 is equal to the thickness d1 of the structural separating element 1.

[0040] On the surface 18 of the separating element 1 opposite the hazardous area 12, the feed-through pipe stub 5 ends open, like a conventional pipe, and has a circumferential external chamfer 57. A wastewater pipe 59 from inside the building can easily be inserted into this open pipe end in a sealing manner, as shown in the Fig. 1 hinted at.

[0041] In the hazardous surface 12 of the basement exterior wall 1, which is intended to prevent any moisture or water ingress along the pipe penetration 100 by means of a coating 16 with a thickness h", an approximately ring-shaped recess 11 with a stepped wall is recessed, in which the sealing flange 52, which is integral with the pipe stub 5, and the coating connection flange 12, which is connected to it via its outer surface 521, in particular by means of adhesive bonding, and which together form the double flange unit 5215, are seated - which is fully encased on the underside and around the perimeter laterally by the material Mt of the building separation element 1.

[0042] The outer surface 151 of the coating connection flange 15 is flush with the hazard surface 12 of the structure separation part 1 itself.

[0043] The substantially ring-shaped coating connection flange 15 is fully and laterally connected to the raised edge ring 522 of the pipe socket 55 in a fluid-medium-tight manner, which in turn is fully connected to the sealing flange 52 by forming the double flange unit 5215.

[0044] The coating connection flange 15 projects radially beyond, preferably uniformly, the sealing flange 52 which is integrally connected to the pipe socket 55 on all sides.

[0045] The recess 11 has a shape that corresponds exactly to the geometric shape of the double flange unit 5215.

[0046] The coating connection flange 15 is made of a material Dm identical to the material Dm of the hazardous area coating 16 or at most chemically closely related material Dm', thereby ensuring a virtually material-integral joint or seamless connection between the hazardous area coating 16 and the coating connection flange 15, which absolutely prevents the passage of fluid media, in particular moisture.

[0047] Regarding the concrete, i.e., actual, manufacturing of the new building separation element 1, e.g., a basement wall, with water / wastewater penetration by "pouring" a formwork that borders the building separation element 1 on both sides with flowable and subsequently hardening building material, in particular concrete, the pipe section 5 according to the invention, i.e., the pipe stub, is installed in the formwork in such a way that the outer surface 151 of the coating connection flange of the double flange unit 5215 lies flush against the inner surface of the formwork wall and is seamlessly encased by the flowable building material Mt introduced into the formwork, which hardens there, whereby, after demolding, the double flange unit 5215 is ultimately arranged in a recess 11 of the building separation element 1 that fully corresponds to its overall shape.The application of the hazard area 16 coating material Dm integral to both the hazard area 12 and the exposed outer surface of the coating connection flange 15 of the double flange unit 5215, in particular based on bitumen, is then carried out by spraying or brushing.

[0048] The Fig. 2 The figure shows, viewed from above, an essentially annular coating connection flange 15 of the double flange unit 5215 with its two sets of two flat sections 58 arranged opposite each other in the edge course and the circular opening with a radius r15, which corresponds exactly to the outer radius of the edge ring 522 of the pipe socket 55.

[0049] The in Fig. 3 In the section view – with otherwise unchanged reference numeral meanings – the component 1 is traversed by two pipe stubs 50' of the twin pipe section 5' arranged at a standardized distance from each other. These stubs share a common, spectacle-like twin sealing flange 52', approximately in the shape of an "8", which connects them. The twin sealing flange 52' is fully connected to the twin coating connection flange 15' via its outer surface 521'. The coating connection flange 15' has a particularly oval outer shape and projects laterally beyond the twin coating connection flange 15' on all sides.

[0050] Together, these two flanges 52' and 15' form the twin double flange unit 5215'. The stabilizing lamellae 51' of the two pipe stubs 50' are arranged at a distance al from each other and are each enclosed by the concrete Mt of the component 1. After the twin pipe section 5' has been encased in concrete, the twin coating connection flange 15' sits in a recess 11' of the component 1 that precisely matches its shape.

[0051] The outer surface 151' of the twin coating connection flange 15' is fully connected to the final full coating 16 of the hazardous area 12 with the same material.

[0052] The in Fig. 4 The underside view of the twin pipeline sections 5' shown is explained - with Fig. 3 with consistent reference symbol meanings - the twin pipeline section 5' in more detail: In the twin pipeline section 5' shown here, - with otherwise consistent reference symbol meanings as per Fig. 3 - the two identical pipe sections 50' are recognizable, wherein in the Fig. 4 The different relative positions of the two stabilizing lamellae 51' can be clearly seen.

[0053] Furthermore, it is shown how the sealing flanges of the two pipe stubs 50' together form the twin sealing flange 52', which has an outer shape approximately of an "8". The twin coating connection flange 15', which is shaped approximately like spectacles and has an oval shape, is fully connected to the upper or outer surface 521' of the twin sealing flange 52', thus projecting beyond it on all sides and forming the twin double flange unit 5215'.
