Definitions

  • the invention relates to an arrangement for insulating and sealing joints having building facades of the type specified in the preamble of claim 1.
  • facades for functional buildings such as production halls for industrial use, but also residential buildings, and in particular high-rise buildings there, have been created on the basis of prefabricated large-area slabs, in particular concrete slabs.
  • the concrete slabs were assembled into facades in the required manner and jointed together. Buildings with such facades are now in need of renovation in large numbers. There is a need for renovation for various reasons. For example, the building facades made of prefabricated panels largely no longer meet thermal insulation requirements. Another problem concerns insufficient moisture protection. In addition, such building facades no longer meet current aesthetic requirements.
  • This conventional structure comprises an outer, water-impermeable cover layer of, for example, external plaster, which may or may not be reinforced with a suitable fabric, and an insulation layer, which preferably consists of an insulation board and is firmly connected, for example glued, to the underlying panel material of the facade.
  • an insulation layer which preferably consists of an insulation board and is firmly connected, for example glued, to the underlying panel material of the facade.
  • This conventional insulation top layer structure for the renovation of building facades has, among other things, the disadvantage that the original, no longer contemporary aesthetic impression of a plate-like building facade is retained even after the renovation.
  • a technically serious disadvantage is that the joints in the insulation top layer structure cause, at least in the long term, sealing problems, since the sealants are exposed to the sun and the atmosphere even after such a refurbishment and tend to become brittle, crack and leak.
  • the conventional insulation top layer structure is not permanently moisture-proof and will therefore require improvement within the foreseeable future.
  • the object of the present invention is a To create an arrangement for insulating joints of building facades of the type mentioned, which in addition to good thermal insulation also ensures a long-term sealing function and gives an acceptable aesthetic impression.
  • the invention provides a joint-free insulation top layer structure which, due to the lack of joint areas, is almost ideally moisture-proof and thus guarantees a permanent renovation of building facades having joints.
  • Another advantage of the joint-free insulation top layer structure according to the invention is the positive aesthetic effect of the building facade renovated with it.
  • the inventive design of the insulation cover layer structure which distributes the deformation peaks and absorbs the overall deformation, can in principle be implemented in a large number of variants.
  • Structural measures in the area of the structural joints are preferred according to the invention, which prevent deformation peaks from the outer skin and the top layer or distribute them to a non-dangerous level.
  • One solution is to decouple the insulation top layer structure in the area of the joints from the underlying building facade areas.
  • a composite-free decoupling area of the insulation layer in relation to the building facade in the area of its joints advantageously extends on both sides of each structural joint over a predetermined area. Outside of this area, the insulation layer of the structure can be firmly connected to the substrate in a conventional manner.
  • a shear-soft connection between the insulation layer and the building facade can be provided in the critical building joint areas, again preferably on both sides of each building joint.
  • the shear-soft composite area is advantageously implemented as a soft one Adhesive layer.
  • a permanently plastic adhesive layer can be provided, or a shear-resistant composite mortar, through which the insulation layer is connected to the substrate, that is to say the building facade.
  • an elastomer layer can also be considered as a shear-soft composite area.
  • the shear-soft composite area may be fiber-reinforced.
  • the insulation layer is formed in multiple layers and the individual layers are arranged in the area of the building joints without any joints.
  • flexible connection zones can also be provided, the material mentioned above, for example a permanently plastic adhesive layer, being considered as flexible material.
  • the measures for uniform distribution of the substrate deformations can also consist in the fact that decoupling areas are provided within the insulation layer, which are designed as compound-free zones or as shear-soft zones in the area of the structural joints.
  • the insulation layer of the structure according to the invention can be firmly connected in a conventional manner to the subsurface, ie the building facade, and the outer cover layer.
  • the insulation layer which is firmly connected to the subsurface is designed to be flexible in the area of the building joints.
  • the insulation layer in this area can have a lower material density than the rest of the insulation layer.
  • a special embodiment consists of fiber insulation boards, which are flexible and expandable in the facade level, but in, by appropriate fiber arrangement and cross-linking Form the thickness direction perpendicular and perpendicular to the facade level.
  • decoupling areas can also be formed in this insulating layer part.
  • the measures for the non-destructive absorption of the substrate deformations by the insulating cover layer structure according to the invention can also be provided in its outer skin, that is to say in the cover layer itself. It is preferred to use a particularly stretchable cover layer section in the area of the building joints.
  • an elastomeric material that may be fiber or mat reinforced may be considered.
  • FIGS. 1 to 4 for insulating and sealing Fingen building facades comprises an insulating top layer structure 1 with an outer skin or a top layer 2 and an inside insulating layer 3, which is fixed outside the respective building joint 4 with the concrete material of the building facade is connected, which is hereinafter referred to as underground 5.
  • underground 5 an insulating top layer structure 1 with an outer skin or a top layer 2 and an inside insulating layer 3, which is fixed outside the respective building joint 4 with the concrete material of the building facade is connected, which is hereinafter referred to as underground 5.
  • measures are taken in each case in the insulating cover layer structure shown in FIGS. 1 to 4, by means of which the deformations of the substrate 5 are absorbed in such a way that this structure, in particular the exterior 2 is not damaged.
  • the various measures provided for this purpose are described in more detail below.
  • the resulting connection-free area 6 can optionally also comprise a separating layer.
  • the non-bonded area 6 is advantageously realized by not coating the substrate 5 with adhesive in an area of the total width 10 on both sides of the building joint.
  • the area 6 can also be designed as a shear-resistant composite between the insulation layer 3 and the concrete base 5.
  • a soft adhesive layer with a width of 10 or a corresponding layer of a push-soft composite mortar, a permanently plastic adhesive layer or a suitable elastomer layer can be considered.
  • FIG. 2 shows a two-layer insulation layer in the form of two adjacent insulation layer plates 3a and 3b instead of the single insulation layer plate 3 from FIG. 1.
  • This two-layer insulation layer has two decoupling areas 6a and 6b, the decoupling area 6a being provided opposite the concrete base 5, similarly to FIG. 1, while the second decoupling area 6b additionally decouples the two insulating layer plates 3a and 3b.
  • Both decoupling areas 6a and 6b in turn extend on both sides of the structural joint 4 with a total width 10.
  • the decoupling areas 6a and 6b like the decoupling area 6 in FIG. 1, can be designed as a zone that is free of connections or soft to the connection.
  • the composite layers 6a and 6b can optionally be fiber or mat-reinforced. Such reinforcement can also be provided in the composite layer 6 of FIG. 1.
  • the single-layer insulation layer 3 (single-layer insulation board) is firmly connected to the concrete base 5, for example glued, also in the area of the structural fingers.
  • a distribution of the deformations is effected by a shear-soft design of the insulation board 3 in the area 7 of the joint 4, namely on both sides of this joint with a total width of 10.
  • the shear-soft zone 7 of the insulation board 3 can be realized in different ways, for example by a lower material density of the board 3 in the zone 7, or by a corresponding fiber arrangement and cross-linking in fiber insulation boards.
  • the outer skin or the covering layer 8 of the insulating covering layer structure 1 is designed to be elastic, specifically at least in an area of the total width 10 opposite the structural joint 4.
  • This area 8 is designed to be particularly flexible and preferably reinforced with mats or fibers.
  • the material for the particularly stretchable area 8 comes e.g. an elastomer into consideration.
  • the insulation layer or insulation board 3 lying under the outer skin 8 is firmly glued to the concrete base 5, even in the critical area of the building joint.
  • the insulation board can also be made non-bonded in this critical area relative to the concrete base 5 or, as described above, can be coupled to the base 5 in a composite-soft manner.
  • a multi-layer insulation board construction can also be used, which is designed, for example, according to FIG. 2.
