Definitions

  • the present invention relates to a mounting system for the thermally separated mounting of an attachment to a wall provided with insulating material, in particular to a wall provided with a thermal insulation composite system.
  • the present invention relates to a method for mounting an attachment to a wall provided with insulating material, in particular to a wall provided with a thermal insulation composite system, using a mounting system according to the invention.
  • Thermal insulation on building walls makes a significant contribution to reducing heating energy.
  • This involves covering a wall with insulating material which can be, for example, insulation panels made of synthetic inorganic material, such as calcium silicate, or insulation panels made of synthetic organic material, such as expanded polystyrene foam.
  • insulation panels can be part of a thermal insulation composite system used to insulate the exterior walls of buildings, cf. https://de.wikipedia.org/wiki/Wärmedämmverbundsystem .
  • wall here and in the following refers only to those components or component sections that have a stable structure, in particular sufficient stability for the anchoring of anchor elements, and for this purpose can be constructed, for example, from concrete, aerated concrete or masonry (e.g. from perforated or solid brick).
  • the fastening must be carried out in such a way that no thermal bridge is formed from the outside through the insulation material to the wall.
  • solutions with anchor elements that include thermally insulating thermal bridge separation modules are known from the state of the art.
  • these solutions are relatively expensive and the thermal bridge separation modules have rather unfavourable geometries that widen outwards, which can lead to such large recesses in the insulation material on the outside that they can no longer be covered by the attachment, which is to be seen as aesthetically disadvantageous at the very least.
  • the insulation material does not have a high level of mechanical stability and can give way under the pressure of the attachment, which - in addition to the poor appearance - can in turn have a detrimental effect on the stability of the attachment.
  • a thermally insulated and mechanically stable fastening of the attachment to the wall provided with insulating material should be achieved.
  • the mounting system comprises at least one anchor element with an anchor section for anchoring in the wall and an adjoining connecting section, the anchor element further comprising a thermally insulating thermal bridge separation module for at least section-wise arrangement in the insulating material, wherein the thermal bridge separation module is connected to the connecting section and has a receptacle for a, preferably screw-in, fastening means for screwing the attachment, the mounting system further comprising at least one thermally insulating support component for arrangement between the wall and the attachment in order to enable direct or indirect support of a first end region of the support component on the wall and direct or indirect support of the attachment on a second end region of the support component opposite the first end region.
  • the anchor section of the respective anchor element can be formed, for example, by at least one section of an anchor rod, a screw or a threaded rod. If necessary, a dowel can be inserted into the wall so that the respective anchor section can be screwed into it.
  • the connecting section can also be formed by a section of an anchor rod, a screw or a threaded rod.
  • a section adjoining this section can form the respective anchor section, i.e. the anchor rod, the screw or the threaded rod in this case comprises both the anchor section and the connecting section or forms them.
  • the connecting section is generally arranged in the insulation material, whereby this is to be understood as meaning that the connecting section is not arranged in the wall because only the anchor section is arranged in the wall and the connecting section adjoins the anchor section.
  • the connecting section can be arranged at least in sections, in particular entirely, in the thermal bridge separation module.
  • thermal bridge separation modules are known from the state of the art and are typically made from a plastic that is a poor conductor of heat.
  • the thermal bridge separation module in particular provides thermal separation or insulation of the connecting section from the fastening means for screwing the attachment part.
  • the thermal bridge separation module can be connected to the connecting section by screwing and/or gluing, for example.
  • the thermal bridge separation module can be arranged entirely in the insulation material or can protrude outwards from it to a certain extent.
  • the holder for the fastening means for screwing the attachment part can be designed differently depending on the fastening means.
  • the holder can have an internal thread into which the fastening means can be screwed, whereby the fastening means in this case can be, for example, a screw or a threaded rod plus nut.
  • the fastening means in this case can be, for example, a screw or a threaded rod plus nut.
  • the attachment In the case of a screw, the attachment is screwed tight with this.
  • a threaded rod the attachment is screwed tight with the nut.
  • a threaded rod plus nut is provided as a fastening means, but the holder does not have an internal thread and the threaded rod is glued into the holder using adhesive.
  • bonding is also possible if there is an internal thread in the holder.
  • At least one thermally insulating support component is provided, which is arranged between the wall and the attachment. Since the attachment is supported directly or indirectly on the second end region of the support component and the support component is supported directly or indirectly on the wall with its first end region, the support component acts as an abutment for the attachment.
  • the support component is contacted directly by the attachment during its assembly.
  • one or more elements can be arranged between the first/second end area and the wall/attached part.
  • a washer or other spacer can be arranged between the attached part and the supporting component.
  • the interposition of a "contamination", such as part of an interior plaster layer, an adhesive or a piece of insulation material, between the first/second end area and the wall/attached part cannot typically be excluded.
  • the supporting component As the term "supporting component” already expresses through its literal meaning, the supporting component as such is not designed to be connected to the attachment part in a tensile manner, in particular screwed. Instead, the supporting component as such serves exclusively to support or absorb compressive forces that the attachment part resting on the supporting component exerts on the supporting component.
  • the support component For thermal insulation of the support component, it can be made at least in sections from a thermally poorly conductive, pressure-resistant material, in particular from a thermally poorly conductive, pressure-resistant plastic.
  • a thermally insulated and mechanically stable fastening of the attachment to the wall provided with insulating material can be achieved.
  • anchor elements and/or support components can be provided.
  • a preferred embodiment of the mounting system according to the invention provides that the support component has a thermal conductivity of at most 0.39 W/(m K), preferably at most 0.1 W/(m K), from the first end region to the second end region.
  • thermal conductivity which is also called thermal conductivity number or thermal conductivity coefficient
  • suitable material selection and/or material arrangement can be achieved by suitable material selection and/or material arrangement.
  • Thermal conductivity is generally a tensorial quantity. "From the first to the second end area” determines the direction, so that information on thermal conductivity in other directions is not necessary or the thermal conductivity in other directions can also take on other values. On the other hand, “from the first to the second End region” clearly expresses that the focus is on the thermal conductivity of the entire support component or over the entire length or extension of the support component from the first to the second end region, whereby it is not excluded that the support component, in particular between the two end regions, has sections with a higher thermal conductivity.
  • the support component can have a reinforcing element for mechanical reinforcement, which in itself can also have poorer thermal conductivity.
  • the support component has an inner thermal insulation element made of a plastic and a reinforcing element which surrounds the inner thermal insulation element in sections, wherein two mutually opposite end regions of the inner thermal insulation element form the first end region and the second end region of the support component at least in sections and wherein at least one of the end regions, preferably both end regions, of the inner thermal insulation element is/are free of the reinforcing element.
  • the inner thermal insulation element forms a thermally isolating or insulating core and can thus ensure sufficient thermal insulation of the supporting component as well as, if necessary, the aforementioned thermal conductivity.
  • the inner thermal insulation element does not need to be particularly stable mechanically, since the Reinforcing element surrounds the inner thermal insulation element in sections, thus still guaranteeing sufficient mechanical stability of the support component as a whole.
  • "In sections" can not only mean that at least one of the end regions of the inner thermal insulation element is free of the reinforcing element, but it is also conceivable that the reinforcing element has a grid or net-like appearance.
  • the inner thermal insulation element can of course also be designed to be mechanically very stable, in particular through the appropriate choice of material.
  • the inner thermal insulation element is made of a pressure-resistant plastic, in particular a thermoplastic or duroplastic or duromer.
  • the inner thermal insulation element in order to ensure optimal mechanical stability, is made of a fiber-reinforced plastic, in particular glass fiber-reinforced or carbon fiber-reinforced plastic.
  • a preferred embodiment of the assembly system according to the invention provides that the reinforcing element is essentially tubular or sleeve-shaped. Accordingly, the reinforcing element can be pushed over the inner thermal insulation element during manufacture of the support component.
  • essentially tubular or sleeve-shaped is to be understood as meaning that the reinforcing element also has lateral holes and/or recesses and/or slots may be present, which in extreme cases may result in a net-like appearance.
  • the reinforcing element is made of an aluminum alloy or a stainless steel or of a carbon fiber reinforced plastic.
  • the support component has a length along a longitudinal axis and that each of the two end regions of the inner thermal insulation element extends along the longitudinal axis over a maximum of 10%, preferably a maximum of 5%, of the length. In this way, it is ensured that the at least one end region of the inner thermal insulation element that is free of the reinforcing element is not too long in terms of mechanical stability.
  • the thermal bridge separation module is made of a plastic, in particular one reinforced with glass fiber or carbon fiber. This improves the mechanical stability of the respective thermal bridge separation module and thus of the respective anchor element.
  • the thermal bridge separation module has a substantially cylindrical outer shape.
  • cylinder is to be understood as essentially a rotary cylinder, unless otherwise stated.
  • the "external" shape of the thermal bridge separation module is to be understood as the shape that results when the thermal bridge separation module is viewed as such from the outside.
  • the recesses required for the thermal bridge separation modules can be made particularly easily using holes. Furthermore, the recesses/holes can be made with a comparatively smaller diameter, and these recesses/holes and the anchor elements or thermal bridge separation modules arranged therein can therefore be easily covered by the respective attachment part.
  • the at least one support component in an assembled state of the assembly system, is arranged behind the at least one anchor element as seen in the direction of gravity. This arrangement results in particularly good and effective support of the load generated by the attachment part due to gravity.
  • a particularly preferred embodiment of the mounting system provides for a plurality of anchor elements, wherein in the assembled state at least two anchor elements are arranged one behind the other in the direction of gravity and wherein between or after two of these anchor elements the at least one support component
  • the arrangement of the at least one support component between two of these anchor elements allows the realization of a relatively compact arrangement. By arranging the at least one support component after two of these anchor elements, extreme loads can also be taken into account.
  • the invention provides an arrangement comprising an inventive mounting system, a wall provided with insulating material and an attachment which is mounted on the wall with the mounting system, wherein the first end region of the respective support component is supported directly or indirectly on the wall and wherein the attachment component is supported directly or indirectly on the second end region of the respective support component.
  • the attachment component is mounted on the wall in a thermally separated manner by means of the inventive mounting system, wherein the support component imparts a counter pressure when the screw connection of the attachment component is tightened.
  • “Fastening the attachment by screwing it to the respective thermal bridge separation module using a fastening device” means that the attachment is screwed in place when it is installed.
  • the fastening device itself does not necessarily have to be screwed to the thermal bridge separation module or its holder, but rather a threaded rod could be arranged in the holder and glued to the thermal bridge separation module. The attachment is then screwed in place using a nut that is screwed onto the threaded rod.
  • a preferred embodiment of the method according to the invention provides that the arrangement of the at least one support component takes place behind the at least one anchor element as seen in the direction of gravity.
  • the assembly system is in an assembled state.
  • a particularly preferred embodiment of the method according to the invention provides for several anchor elements to be provided, with at least two anchor elements being arranged one behind the other in the direction of gravity and with at least one support component being arranged between or after two of these anchor elements.
  • the Assembly system in the assembled state.
  • the arrangement of at least one support component between two of these anchor elements allows a relatively compact arrangement to be achieved.
  • extreme loads can also be taken into account.

  • the attachment 10 is screwed tight with nuts 9, which are arranged one below the other or one behind the other as seen in the direction of gravity 16.
  • the attachment 10 is supported on a support component 12 of the mounting system 1, wherein the support component 12 is in Fig.1 is covered by the attachment part 10 and is therefore not directly visible, but only indicated.
  • the support component 12 is arranged between the two nuts 9, whereby the nuts 9 and the support component 12 are arranged on a straight line parallel to the direction of gravity 16 or on the vertical section line II-II.

  • Each anchor element 4 has an anchor section 5 which is anchored in the wall 2.
  • the anchor section 5 is formed by a section of a threaded rod 8, wherein the threaded rod 8 also forms a connecting section 6 of the anchor element 4 adjoining the anchor section 5.

  • the thermal bridge separation module 7 is intended for at least partial arrangement in the insulation material 3 or the thermal bridge separation module 7 and the connecting section 6 are in Fig.2 arranged in the insulation material 3.
  • the thermal bridge separation module 7 has a receptacle 11 for a threaded rod 8', which is screwed into the receptacle 11 in the first embodiment shown.
  • the receptacle 11 has an internal thread (not shown) for this purpose.
  • the nuts 9 interact with the threaded rods 8', with one nut 9 and one threaded rod 8' each forming a fastening means for screwing the attachment part 10 tight.
  • the support component 12 has a first end region 18, with which the support component 12 is supported directly on the wall 2. Opposite the first end region 18, the support component 12 has a second end region 19, which points away from the wall 2 and on which the attachment 10 is directly supported.

  • the support component 12 has a thermal conductivity ⁇ of approximately 0.35 W/(m K) from the first end region 18 to the second end region 19.
  • Both the support component 12 and the thermal bridge separation modules 7 have a cylindrical shape when viewed from the outside. This allows recesses in the insulation material 3 for the thermal bridge separation modules 7 and the support component 12 to be easily produced by means of drilling holes.
