Definitions

  • the invention generally relates to the mounting of an insulating material to a substructure with the aid of a Justiersübels and in particular the attachment of the insulating material and adjustment of its distance from the substructure.
  • the plates are attached to a substructure by means of a holding element.
  • the plates may also have a multilayer structure and consist, for example, of a mixture of materials or of a material which has different densities or is compressed differently.
  • the retaining elements are often referred to as dowels or insulation dowels.
  • insulation materials are fastened to a substructure with a known retaining element, then the insulating material is fixed between the one end of the retaining element and the other end of the retaining element, with which the retaining element is anchored in the substructure.
  • the retaining element presses the insulating material to the substructure, ie the insulating material hugs the substructure and takes on its contour. It may happen that the unevenness of the substructure and the surface formed by the insulation boards is uneven. For example, the insulation panels may have an offset to each other. This means that the insulation boards do not form a homogeneous surface.
  • the balancing and bonding work is complex and require additional use of materials.
  • the holding elements compress the insulation board on one side more than at the other, so exert stronger pressure on one side than on the other, for example, by different setting depths of the holding element.
  • insulation boards which are multi-layered and, for example, have a soft layer and a harder layer
  • the offset of the insulation boards can be very large, because the soft layer, usually the substructure facing, can be easily compressed.
  • the unevenness that results from the offset of the insulation panels are normally compensated by the final application of the plaster layer. This means that a plaster layer must be applied which does not have the same thickness at all points. This can lead to stress cracks etc. in the case of different environmental influences such as moisture and temperature.
  • the invention is therefore based on the object to provide a holding element in the form of a dowel and a generic method, which does not have the aforementioned disadvantages, i. with a distance between the surface of the insulating material and the substructure with simple means is flexibly adjustable so can be adjusted so as to provide a homogeneous surface, so that a uniform layer of plaster can be applied. Furthermore, the object is to provide a holding element and a method with which the insulating material can be attached to the substructure to be dismantled.
  • An inventive dowel for fixing an insulating material and for adjusting a distance of the insulating material from a substructure has, a fastener, which has a first end portion and a second end portion.
  • the first end region of the fastening element is adapted for anchoring the anchor in the substructure.
  • This anchoring can be direct or indirect.

  • the fastener has no or only insignificant contact with the substructure.
  • the fastener also has a second end portion opposite to the first end portion and having disposed thereon a means for holding the insulation material, wherein the means for holding is adapted to be steplessly moved along the second end portion of the fastener. That the means for holding can be moved relative to the second end region of the fastening element. That the distance between the first end region of the fastener and the means for holding is adjustable, i. adjustable.
  • the means for holding can be designed such that this can dig into the insulating material, anchoring or otherwise come into contact, that when the means for holding along the second end portion of the fastener is moved, the insulating material also performs a corresponding movement. That when the fastener is anchored in the substructure and the means for holding moves along the second end portion of the fastener, the insulation material is either moved closer to the substructure or moved away from the substructure. If the means for holding it exerts pressure on the insulating material, then this is compressed when it is pressed against the substructure. Conversely, if the means for holding pull on the insulating material, it will decompress.
  • the distance between the surface of the insulating material, ie the side facing away from the substructure of the insulating material and the substructure is adjusted or adjusted.
  • the insulating material is thereby compressed, for example, with an increase in the distance, the insulating material is decompressed, for example.
  • the adjustment of the distance is infinitely variable along the second end region of the fastening element without the fastening element being loosened, that is to say without the anchoring being weakened.
  • this has a Dübelschaft, which receives the fastener at least partially.
  • the dowel shaft and the fastener can cooperate in such a way that the dowel is anchored in the substructure.
  • the anchor shank can be introduced into a bore hole in the substructure and the first end region of the fastening element can be introduced into the anchor shank and spread it, so that an anchoring takes place by spreading in the substructure.
  • the fastening element may also be referred to as a spreading element.
  • the spread of the spreader end portion of the dowel shaft can also be referred to as a spreading zone, which serves to anchor the dowel shaft and thus the dowel in the substructure.

  • the means for holding for example, already be applied at the factory in a certain position on the thread of the fastener, and can be moved along the thread by rotating the means for holding in a different position. As a result, the distance between the first end portion of the fastener and the means for holding is adjusted. In this case, the distance to the first end region of the fastening element can be reduced or increased depending on the direction of rotation of the means for holding.
  • the insulating material is moved closer to the substructure.
  • the distance between the first end region of the fastening element and the means for holding is increased. In this case, this distance can even be so large that the insulating material is lifted from the substructure, so it form a free space between the substructure facing side of the insulating material and the substructure.

For example, when the second sleeve engages the second end portion of the fastener and is rotated, the second sleeve moves along the thread, i. along the second end portion of the fastener. Since the first and second sleeves are freely rotatable relative to each other, the first sleeve does not have to perform the rotational movement of the second sleeve.
