Definitions

  • the invention relates to a drain arrangement with a drain container and a sealing sleeve designed in the form of a surface-extending film according to the preamble of claim 1.
  • the invention further relates to a method for producing such a drain arrangement.
  • the drain container usually has a plastic section that forms the top of the drain container.
  • the drain container has an inlet opening on its top, and offset from the top downward, the drain container usually has an outlet opening for connection to a drain pipe.
  • the inlet opening is designed to receive waste water.
  • the top of the drain container forms a drain gutter in which waste water is collected and led to the inlet opening, via which the waste water can then get into the drain container and from there into the sewage system via the outlet opening.
  • the drainage channel is designed as a separate component from the drainage container, the drainage channel having a channel connection piece and the discharge opening being designed to receive the channel connection piece.
  • the sealing sleeve is usually on the top arranged of the drain container and connected to the drain container via a sealing connection. This sealing connection forms a closed sealing line running around the inlet opening, so that the sealing sleeve around the inlet opening is connected to the outlet container in a watertight, sealing manner.
  • watertight preferably means that in a test according to DIN EN 1253, part 1, as of March 2015, the drain arrangement, when used as intended, prevents water from escaping at the points sealed as "watertight".
  • the sealing sleeve extends laterally away from the sealing line beyond the drain container.
  • the integration of a generic drain arrangement into a room floor usually takes place as follows: The drain tank is placed on a bare floor in such a way that its upper side points upwards in the room. A drain pipe is connected to the drain opening. Then a floor covering, usually screed, is applied to the bare floor, which includes the drain pipe and the drain container at least in sections. A first sealing plane is then created in the room. This is done by sealing the floor covering of the room floor, for example using a sealing coat with a paste, a flocked sealing membrane or a welding membrane.
  • the sealing sleeve is integrated into this first sealing level, for example by gluing or by applying a coat of paint to the floor covering and sealing sleeve.
  • the sealing collar starting from the sealing line, the sealing collar must extend laterally beyond the drain container so that it can be connected laterally, ie outside the inlet opening, to the top of the screed in a sealing manner.
  • the sealing sleeve usually has an overhang section which, starting from the sealing line, extends laterally beyond the drain container and which realizes a flat surface which runs around the drain container Connection between the sealing sleeve and the screed enables.
  • This overhang section usually takes up at least 80%, in particular at least 90%, of the areal extent of the sealing sleeve.
  • a reliable sealing connection between the sealing collar and the adjoining screed can thus be realized via this overhang section which extends over a considerable area.
  • the sealing connection does not necessarily have to be made directly on the screed, it can also be done, for example, with a tile adhesive that is applied to the screed.
  • the generic drain arrangement is properly integrated into a room floor in such a way that the sealing sleeve can realize a sealing connection between a floor covering surrounding the drain container, such as screed, and the drain pan.
  • a floor finish is then applied to the first sealing level, which is usually sealed watertight on its surface and which forms the floor surface.
  • This bottom end is usually connected to a drain gutter, which in particular has a gutter connection which is connected to the drain container and opens into the inlet opening of the drain container, or which is in particular integrated in the drain container.
  • the bottom end and the top of the drainage channel are usually connected to one another via a seal that runs around the drainage channel, so that the bottom end, seal and drainage channel form a second sealing level.
  • the first sealing level serves to prevent water from penetrating into the building even if the second Sealing level has leaks, for example leaks in the joints of the floor or Leaks in the seal around the gutter.
  • the sealing connection running around the inlet opening between the sealing collar and the top of the drain container is absolutely necessary for the functionality of the drain arrangement according to the invention with regard to its intended use as described.
  • this sealing connection must also be able to withstand a not inconsiderable mechanical load without losing its sealing properties. Because when the drain arrangement is integrated in a room, the sealing sleeve is spread out and mechanically held on it while it is sealingly connected to a floor covering, such as screed, which places a not inconsiderable load on the sealing connection.
  • sealing sleeves usually have a fiber layer, for example flocking or a fleece, at least on their underside, so that they can be reliably sealed with a sealing coating on a floor covering that surrounds the drain container as explained.
  • an adhesive When gluing to the flange of the drain container, an adhesive must penetrate the entire fiber layer in order to create a watertight connection with the actual sealing layer, which is laminated from the underside through the fiber layer. Depending on the viscosity of the adhesive, this is a major challenge. If the fiber layer is not completely penetrated in an adhesive connection, water is transported along the fiber by the capillary effect. The necessary watertight sealing connection is not provided.
  • the adhesive connections described are also a mechanical weak point and often cause drainage arrangements not to pass the strength tests described.
  • EP 2 423 395 A1 discloses a drain container which is sealed against a floor surface via a sealing membrane.
  • US 2010/0319281 A1 discloses a drain assembly with a drain container having a flange on which a sealing membrane is arranged.
  • DE 20 2006 019 814 U1 discloses a drain arrangement with a drain container, on the top of which a flange is formed, to which a sealing membrane is applied.
  • the present invention has for its object a To provide a sequence arrangement with which the described problems of generic sequence arrangements can be at least partially eliminated.
  • the invention is also based on the object of providing a method for producing a drain arrangement with which the described problems occurring in the case of generic drain arrangements can be at least partially eliminated.
  • the drain arrangement according to the invention has a drain container and a sealing sleeve.
  • the sealing sleeve has a shape in the manner of a flat film.
  • the sealing sleeve thus extends horizontally over a considerable area and has a very thin thickness perpendicular to the horizontal, so that the sealing sleeve can be applied flexibly to surface structures.
  • the sealing sleeve is particularly preferably designed to be elastic along at least one horizontal direction, in particular along two mutually perpendicular horizontal directions, in such a way that when a force is applied along the corresponding horizontal direction, starting from its rest position, in which no force is applied, by at least 5%. its extension along this horizontal direction is extendable and shrinks elastically to its original size in the rest position when the application of force is ended.
  • the drain container has a plastic section which forms an upper side of the drain container.
  • the entire drain container is particularly preferably made of plastic.
  • the drainage container is preferably made of a rigid material, so that it has no elastic properties, as described, for example, for an embodiment of the sealing sleeve.
  • the drain container is designed as a drain pot, which is made of plastic and in which the plastic section is integrally produced in one piece and thus integrated.
  • the drainage container has a drainage pot, preferably made of plastic, the plastic section being a plastic element separate from the drainage pot, which has the inlet opening, it being arranged relative to the drainage pot in such a way that the inlet opening is connected to one at the top of the Drain opening provided.
  • the plastic section can have a nozzle for this purpose, which opens into the opening of the drain pan, the nozzle being sealed off circumferentially from the opening.
  • Drain container on its upper side which is formed by the plastic section and is therefore also the upper side of the plastic section, has an inlet opening.
  • a drain opening which is suitable for connection to a drain pipe, is provided in the drain container from top to bottom.
  • the sealing sleeve is connected at the top of the drain container to the drain container via a sealing connection to form a closed sealing line running around the inlet opening and extends laterally beyond the sealing container from the sealing container.
  • the sequence arrangement according to the invention can have further features which have been explained above with reference to sequence arrangements of the generic type. Likewise, the sequence arrangement according to the invention can be used as intended, in particular as described for the sequence arrangements of the generic type.
  • the sealing connection via which the sealing sleeve is connected to the top of the drain container while forming the sealing line, is produced by welding the sealing sleeve to the drain container.
  • the sealing line is designed as a weld seam.
  • a plastic bead is formed on the top of the drain container on a side of the weld seam facing away from the inlet opening.
  • the plastic bead is thus formed at the transition from the sealing line to the overhang section.
  • the drain arrangement according to the invention has significant advantages over conventional drain arrangements.
  • the welding of the sealing sleeve makes it particularly reliably watertight due to the integral connection that the welding creates per se Sealing connection between the sealing sleeve and the drain container guaranteed.
  • the welding enables the connection to be subjected to outstanding mechanical strength.
  • the inventors took a completely different route with welding than was previously done in the prior art. This is because the inventors have recognized that, despite the very thin and mechanically fragile design of the sealing sleeve, it is possible to weld the sealing sleeve to the plastic section.
  • the inventors have found that, in principle, a corresponding sealing connection is possible both by mirror welding and by hot air welding as well as by ultrasonic welding and by hot gas welding.
  • the inventors have recognized that during welding it is possible to form a bead on the top of the drain container on the side of the weld seam facing away from the inlet opening.
  • the essential property of the bead for the invention is that it has a rounded and thus no sharp-edged surface. Accordingly, the sealing sleeve with its overhang section, with which it extends laterally away from the sealing line over the drain container, can rest against the rounded surface of the plastic bead.
  • the inventors have recognized that the drain arrangement described can be produced particularly inexpensively. This is because the sealing sleeve and the drain container can be produced independently of one another as separate components, the drain container being particularly preferably produced using an injection molding process. Only in a subsequent process step can the separately manufactured components be welded together get connected.
  • the sealing line ie the weld seam, can be made very narrow because of the outstanding connecting properties of the weld seam.
  • the inventors have recognized that the formation of the sealing line with a width of less than 10 mm, in particular less than 7 mm, in particular less than 5 mm still enables the formation of a sufficiently mechanically stable and watertight sealing connection between the drain container and sealing sleeve.
  • the width relates to the extension length of the sealing line, with which it extends in the horizontal direction and thus perpendicular to the vertical direction, to which the directions “above” and “below” refer in the present case, and extends continuously around the inlet opening of the width mentioned.
  • connection between the sealing collar and the drainage container can only be provided by a corresponding very thin sealing line or weld seam, it is in particular possible to install the drainage arrangement in a room floor also very close to walls, since there is no wide flange on the drainage container for the connection must be provided with the sealing sleeve.
  • the sealing connection between the sealing collar and the drain container and thus the weld seam is designed such that the sealing connection is subjected to a peel test with a standardized tensile force of 100 N during a strength test according to the standard DIN 1253-2, 10.4.3 withstands a tensile force that exceeds the standardized tensile force during the peel test.
  • the drain arrangement has particularly outstanding mechanical properties, since the sealing connection between the sealing sleeve and the drain container can withstand a higher mechanical load than this according to the standard is required. The inventors have recognized that such a drain arrangement can be realized by welding the sealing sleeve to the plastic section of the drain container and has particular advantages for a fitter.
  • the sealing connection withstands a tensile force that exceeds the normalized tensile force by at least 5%, in particular by at least 10%.
  • the sealing sleeve is designed as a multilayer film which comprises a plastic sealing film, a fiber layer being arranged both on the top and on the underside of the plastic sealing film.
  • the plastic sealing film is made in particular from PE (polyethylene), PP (polypropylene), EPDM (ethylene-propylene-diene rubber) or TPE (thermoplastic elastomer).
  • the plastic sealing film is responsible for the sealing properties of the sealing sleeve.
  • the fiber layers on the top and bottom are particularly advantageous both for protecting the plastic sealing film and for better connectivity of the sealing sleeve to adjacent materials, such as a sealing coat on a screed or a tile adhesive.
  • the fiber layers can be formed, for example, by flocking or by a fleece.
  • At least one of the fiber layers is preferably made of plastic.
  • at least the plastic sealing film and the fiber layer arranged on the underside of the plastic sealing film are fused to the plastic section of the drain container in the weld seam. Only the plastic sealing film and the fiber layer arranged on the underside of the plastic sealing film are particularly preferred in the weld seam, but not the one arranged on the upper side of the plastic sealing film Fiber layer fused to the plastic section of the drain container. This can particularly preferably ensure that the properties of the top fiber layer are not influenced by the welding, so that the top fiber layer can continue to be suitable for a particularly good connection with adjacent materials.
  • a cohesive connection is formed at least between the plastic sealing film and the plastic section.
  • a corresponding material connection to the underside fiber layer can also be established.
  • the underside fiber layer is enclosed in the material connection, which is formed by the melting of the plastic sealing film and the plastic section in the weld seam, without forming a material bond, and is thus also fused in the weld seam.
  • the invention further relates to a method for producing a drain arrangement, which comprises a sealing sleeve designed in the form of a flatly extending film and a drain container.
  • the drain container has a plastic section, which forms the top of the drain container with its top.
  • the drain container has an inlet opening on its upper side and an outlet opening offset from the upper side for connection to an outlet pipe.

  • the sealing sleeve is first placed on the top of the plastic section during the second method step, after which the welding is then carried out using a welding method.
  • the sealing sleeve and plastic section are heated during the welding process before the sealing sleeve is placed on the top of the plastic section, after which the sealing sleeve is then placed on the plastic section and the weld seam is produced.
  • the sealing sleeve is thus placed on the top of the plastic section during the welding process.
  • a first temperature is set during the welding, to which the sealing sleeve is heated during the welding.
  • a second temperature is set during the welding, to which the upper side of the plastic section is heated during the welding.

Due to the respective temperature settings, the properties of the different materials of the sealing sleeve or plastic section can be taken into account in a particularly targeted manner. Accordingly, the welding can be controlled very precisely via this embodiment according to the invention and damage to the sealing sleeve can be prevented particularly effectively.
