Definitions

  • the invention relates to an anchor rod fastening assembly for a ventilated facade, a facade fastening system and a ventilated facade.
  • a curtained, rear-ventilated facade is a multi-layered external wall construction, which is specified in more detail, for example, in DIN 18516-1:2010-06.
  • curtain, rear-ventilated facades can be attached, for example, by means of anchor rods that are anchored to a load-bearing structure, in particular in a load-bearing wall of a building.
  • the load-bearing wall is typically an outer wall of a building, to which flat clothing elements of an outer clothing can be fastened directly or indirectly, for example via additional support profiles or otherwise designed support means, such as angles or the like, by means of anchor rods and brackets screwed onto them.
  • the cladding elements which are typically arranged plane-parallel to the load-bearing wall, form the outer surface of the facade that is visible to the outside and also serve as protection, especially against driving rain.
  • the anchor rods space the cladding elements from the wall in a lateral direction.
  • Between the clothing elements and the supporting one Construction thus forms a gap in which insulation material, for example stone or mineral wool, is inserted for thermal insulation.
  • the insulating material is typically arranged immediately adjacent to the load-bearing structure or wall.
  • the space formed between the clothing elements and the supporting structure is not completely filled with insulating material; rather, a gap is typically formed directly behind the clothing elements, which serves in particular to remove moisture that has penetrated through rear ventilation.
  • anchor rods and brackets Since the clothing elements are attached to the supporting structure via the anchor rods and brackets, strict requirements are placed on the holding force, stability and load-bearing capacity of the anchor rods and brackets.
  • anchor rods and brackets must absorb both the weight of the facade and wind forces, i.e. forces parallel and normal to the supporting structure.
  • the holders in particular have sufficient resistance to structural failure caused by heat.

Furthermore, an appropriate facade fastening system and a rear-ventilated curtain wall should be provided.
  • the mounting surface is designed for at least indirectly fastening at least one cladding element of the rear-ventilated facade.

  • the free end of the anchor rod is to be understood as meaning that end which faces away from the load-bearing structure and/or protrudes when the anchor rod is fastened to the load-bearing structure, e.g. on a load-bearing (outer) wall. Because the second area and thus the mounting surface protrude over the first area, it is possible to use shorter anchor rods.

  • At least two locking components can be present, which have mutually complementary bayonet lock-like connecting elements which are brought into a bayonet lock-like locking position in the pre-assembly configuration.
  • Corresponding bayonet locks enable a configuration with loosely interlocking components, which are at least possible through the bayonet lock are partially fixed to each other. The handling of the anchor rod fastening assembly can therefore be simplified, for example when attaching it to the anchor rod.
  • the mounting component and at least one of the locking components can have mutually complementary groove-tenon connecting elements, which are brought into engagement in the pre-assembly configuration by displacement in the longitudinal direction of the anchor rod fastening assembly.

  • a facade component 62 attached to the mounting component 2 transmits the load in the direction of gravity S acting weight force FG essentially via a force triangle D defined by the shape of the assembly sword on the anchor rod 5.
  • the weight force FG is at least partially divided into tensile forces FZ and compressive forces FD, which act in the direction of the longitudinal axis of the anchor rod 5.
  • the bending load exerted on the anchor rod 5 by the weight FG can therefore be reduced.
  • An advantage of the anchor rod fastening assemblies proposed in various embodiments can also be seen in the fact that in embodiments in which the fastening blade and/or the fastening blade protrude beyond the anchor rod 5 in the assembly position, the anchor rod can be made shorter, which may reduce the bending moment can be. Shorter anchor rods are advantageous in terms of material savings, especially since anchor rods are comparatively complex and are usually thermally insulating. In some circumstances, thinner anchor rods can also be used.
