Definitions

  • the present invention relates to a built-in element, in particular a sink, for insertion into a receiving opening of a worktop, the built-in element having at least one holding element.
  • the present invention relates to a method for fixing a built-in element, in particular a sink, at the edge of a receiving opening for the built-in element in a worktop, the built-in element having at least one holding element.
  • an installation element which has a holding element designed as a holding web and can be fixed in a recess in a worktop by inserting the holding web into holding clamps fixed at the edge of the recess and anchoring it in the holding clamps by latching.
  • This known method has the disadvantage that additional components, namely the retaining clips to be fixed on the worktop, are required and that the edge of the receiving opening in the worktop must be cut with small tolerances so that the retaining element can be snapped into the retaining clips.
  • the present invention is therefore based on the object of providing a method of the type mentioned at the outset which enables simple and rapid fixing of the built-in element on the worktop.
  • the steps of arranging the volume-changing material on the built-in element, on the holding element and / or on the worktop and / or between the built-in element and the worktop on the one hand and arranging the built-in element in the receiving opening of the worktop on the other hand can be carried out in any order.
  • part of the volume-changing material is arranged on the mounting element on the holding element and / or on the worktop, that the mounting element is then arranged in the receiving opening of the countertop, and that another part of the volume-variable material is then arranged on the mounting element, is arranged on the holding element and / or on the worktop and / or between the built-in element and the worktop.
  • the holding element can be formed in one piece with the installation element or, alternatively, can be designed as a part separate from the installation element, which is connected to the installation element.
  • volume-changing material is understood to mean a material which, in particular through chemical reaction, directly or indirectly, undergoes a, preferably irreversible, volume change which is greater than any thermal expansion of the ambient temperature caused by changing the ambient temperature material.
  • the solution according to the invention is based on the concept of not locking the holding element connected to the installation element with a holding clip arranged at the edge of the receiving opening, but instead of forming a clamping body made of the volume-variable material, which exerts a downward resulting force on the holding element, which braces the built-in element with the worktop.
  • the clamping body is preferably a solid body so that it can transmit pressure, thrust and / or tensile forces to the holding element.
  • This concept offers the advantage that the outer edge of the built-in element can rest on the worktop essentially without gaps or at least with few gaps, since the realizable vertical distances between the built-in element and the worktop are not predetermined by discrete locking steps.
  • the final shape of the clamping body is not yet certain before the volume change of the volume-changing material, so that the clamping body can adapt to the respective local distance between the edge of the worktop on the one hand and the holding element on the other hand, and in this way cutting tolerances of the receiving opening of the worktop can be compensated for can.
  • the concept according to the invention has the advantage that no retaining clips or similar fastening elements have to be prefabricated and fixed on the edge of the receiving opening before the installation element is arranged in the receiving opening.
  • the mounting element can be automatically centered in the receiving opening.
  • volume-variable material is arranged on the mounting element and / or on the holding element and / or on the worktop before the installation element is arranged in the receiving opening of the worktop, so the installation of the built-in element on the worktop can be done completely from above the worktop, without it being necessary for the fitter to go into the space below the worktop to carry out one or more assembly steps.
  • the holding element is advantageously fixed on the installation element before arranging the volume-variable material.
  • an expandable material is used as the volume-variable material.
  • a clamping body is created from the expandable material, which exerts a resulting compressive force on the holding element of the built-in element, which leads to the fact that the built-in element is pulled against the worktop.
  • a foamable material can be used as the expandable material.
  • Such a foamable material can contain, for example, components which outgas and thereby cause the material to expand.
  • the foamable material can contain microspheres which are filled with such outgassing constituents and increase their volume during outgassing until the final volume is reached.
  • a plastic foam preferably a two-component plastic foam, in particular a two-component polyurethane foam, is used as the foamable material.
  • a suitable 2-component polyurethane foam is, for example, the rigid foam sold under the name RAKU-PUR® 34 by Rampf G easilyharze GmbH & Co. KG, Alb No 37, 72661 Grafenberg, Germany.
  • the expandable material expands to its final volume in at least two successive stages.
  • Such a two-stage expansion can be brought about, for example, by overdosing a hardener component in relation to a component of the expandable material to be hardened.
  • the expandable material enters into a material connection with the worktop and / or with the holding element in a first expansion stage.
  • the clamping body is integrally and / or non-positively connected to the worktop and / or to the holding element.
  • the adhesion of the tensioning body to the holding element facilitates the transfer of compressive and / or tensile forces from the tensioning body to the holding element.
  • the adhesion of the clamping body to the worktop also facilitates the transfer of reaction forces from the worktop to the clamping body.
  • a cut surface of the worktop facing the receiving opening for the installation element is sealed by the clamping body.
  • the worktop is often designed as a chipboard and is therefore sensitive to moisture.
  • variable-volume material By sealing the cut surface of the worktop by means of the variable-volume material, there is no need to seal the cut surface of the worktop in an additional operation by means of a separate sealing material, for example a silicone material, against the ingress of water from the receiving opening into the worktop.
  • a separate sealing material for example a silicone material
  • a holding element with a contact surface is advantageously used, which is acted upon by the clamping body with a compressive force which has a downward-pointing component.
  • this contact surface In the assembled state of the built-in element, this contact surface can be oriented essentially horizontally or it can be inclined to the horizontal.
  • a particularly favorable transmission of compressive forces from the clamping body to the holding element is achieved if a holding element is used with a contact surface whose edge on the worktop in the assembled state of the built-in element is lower than its edge facing away from the worktop.
  • a holding element is advantageously used which lies flat against the underside of the installation element. This is particularly advantageous when the contact of the holding element enables the torque or tensile forces introduced to be supported.
  • the holding element bears against an inclined edge of the installation element.
  • the holding element can be welded and / or glued to the installation element.

  • the holding element is advantageously fixed in the region of a folding line of the installation element on the installation element, preferably welded to the installation element.
  • the holding element is fixed, preferably welded, to the installation element in the region of a fold line between an edge slope and an essentially horizontal edge region of the installation element. It is particularly expedient if a holding element is used which comprises a leg with a section facing the worktop and the holding element is fixed, preferably welded, to the installation element in the region of this section. As a result, advantageous leverage and torque ratios are achieved.
  • the clamping body partially, preferably approximately 50% to approximately 90% of the volume of the expansion chamber, fills an expansion chamber delimited by the holding element on the one hand and the worktop.
  • the volume-variable material expands in an expansion chamber delimited by the holding element on the one hand and the worktop on the other hand, an upper end of the expansion chamber thereby is closed that the holding element rests on the worktop.
  • the receiving opening is particularly easy to produce if it is provided that an edge surface of the worktop delimiting the receiving opening is oriented substantially vertically.
  • the edge surface of the worktop delimiting the receiving opening is inclined at least in sections against the vertical.
  • the edge surface of the worktop is inclined towards the vertical in such a way that the receiving opening widens downward.
