Definitions

  • the invention relates to a Untersparren insulation system for a roof, in particular a pitched roof, consisting of at least one insulating element which is arranged between two spaced and arranged under rafters of the roof components, such as counter battens and at least one holding element, with which the insulating element against falling out a space formed between the components is held. Furthermore, the invention relates to a holding element for at least temporarily fixing and / or fixing an insulating element between two spaced and under rafters of a roof, in particular a pitched roof arranged components, such as counter battens with a leg and a leg connected to the bracket for reaching over the device.
  • Sub-frame insulation systems for a pitched roof are known from the prior art. These are insulation systems that are arranged in addition to an intermediate rafter insulation system between arranged under the rafters counter battens. Such a rafter insulation system is usually made of insulating elements, which are arranged for example by clamping between the counter battens.
  • insulation elements Since the heat transfer resistance increases with increasing density of insulating elements made of mineral fibers and the production of such high-density insulation elements is costly and leads to difficult processing, it is advantageous in the field of roof insulation to process insulation elements which have a relatively low density and therefore have a low inherent rigidity , About that In addition, insulation elements are processed with low material thickness in the sub-rafter insulation, which in turn have only a low intrinsic stiffness, so that the trapping of such insulation elements is difficult.
  • a Untersparren- insulation system which has a holding device for securing the insulation elements against falling out of the gap between the counter-battens.
  • This holding device can for example consist of a cross-sectionally U-shaped bracket having two legs and a web connecting them, wherein at the free ends of the legs outwardly directed, are arranged parallel to the web sections.
  • This bracket is pushed over a counter-batten, so that the legs run in the direction of the surface normals of the insulation elements in the intermediate rafter insulation.
  • the insulation elements of the sub-rafter insulation can be placed.
  • This fastener has the disadvantage that the installation between the counter battens and the previously installed intermediate rafter insulation often causes the insulation elements of the intermediate rafter insulation or the intermediate rafter insulation covering the space vapor barrier are damaged.
  • Another holding device is known from this publication, which consists of flat elements which are attached to the counter battens. For example, the attachment by means of screws or nails. This embodiment of the holding device leads to a prolonged processing time for the creation of the intermediate rafter insulation.
  • the invention is the object of the invention to further develop a Untersparren insulation system and a holding element such that the above-described disadvantages of the prior art are avoided, in particular the holding element in a simple way in the pitched roof, in particular at the counter battens can be fastened, without damaging the previously mounted construction elements, in particular the insects and the vapor barrier covering the insectsparparendämmung.

  • the retaining element can thus be formed from a bracket with a U-shaped cross-section and a leg arranged thereon for supporting an insulating element, wherein the bracket has a bearing leg, with which the bracket bears against the component, namely a counter-battens.
  • the holding element has two aligned in opposite directions and in a substantially having identical plane extending legs.
  • another abutment leg is provided which extends with the leg in an identical plane and parallel to the first bearing leg of the bracket.
  • the leg, which adjoins the bracket extends in a plane with the bearing arm of the bracket, so that overall results in an h-shape of the retaining element.
  • retaining elements according to the invention can be pushed in a simple manner over a counter-batten, without having to lift a previously installed intermediate-par-natural insulation.
  • the installation of such a Untersparren insulation system is thus considerably simplified in comparison with the prior art, the risk of damage to the insects is reduced.
