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.
  • Such an arrangement is known from FR-A-2 378 152. It comprises a multi-layer structure with a rubber-elastic sheet that is glued to the substrate with adhesive with a bond.
  • the surface structure consists of a filler layer, fabric layer and plaster layer and is applied to the surface of the elastic rubber sheet.
  • This arrangement bridges the joints and can withstand joint displacements of up to 15 mm. This is caused by the elastic film that is glued to the entire surface of the substrate.
  • the arrangement protects against moisture and heat, but is not itself thermal insulation, although it makes an additional contribution to thermal insulation.
  • a disadvantage of the elastic arrangement is the restoring force or tension that builds up due to a joint displacement. In the long run, this tension leads to the rubber-elastic web becoming detached or to an accelerated aging of the material under tension, so that this is only a temporary solution.
  • FR-A-2 394 551 describes an arrangement for bridging joints or cracks.
  • This arrangement is a complex tape, ie a strip of fabric, under which a plastic tape is glued.
  • the plastic tape can cover a tear.
  • the strip of fabric is inserted into the top layer, the plaster, to fix the plaster on To hold plastic tape.
  • This complex tape is applied to the joint area and stabilized by a flexible covering.
  • This tape thus only serves to bridge fingers or cracks, whereby cracks can again arise in the crack or joint cover when the joint is shifted again.
  • a major need for the renovation of the building facades in question relates to the building joint area, which experience has shown that not only is it badly affected by weather conditions, but also can no longer follow the recurring deformations of the facade panels without damage. Cracks in the joint seals, detachments, water ingress into the construction and in the insulation layer are the consequences.
  • 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 panel and is firmly connected, for example glued, to the underlying panel material of the facade.
  • an insulation layer which preferably consists of an insulation panel 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 fingers in the insulation cover 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 to provide an arrangement for insulating building facades of the type mentioned at the beginning which, in addition to good thermal insulation, also ensures a safe sealing function in the long term and conveys an acceptable aesthetic impression.
  • a joint-free decoupling area of the insulation layer of a predetermined width in the area of the building joints provides a joint-free insulation top layer structure which, due to the lack of joint areas, is almost ideally moisture-proof and thus ensures permanent renovation of building facades with fingers.
  • Another advantage of the joint-free insulation top layer structure according to the invention is the positive aesthetic effect of the building facade that has been renovated with it.
  • the cover layer of the structure which is fundamentally relatively thin, and which also has the sealing function, is particularly at risk of damage.
  • the insulation top layer structure according to the invention prevents deformation peaks from the outer skin and the top layer or distributes them to a non-dangerous level.
  • the outer skin of the structure itself can be formed so elastically that it can withstand even partially increased deformations without the formation of cracks.
  • the non-bonded area advantageously extends over a predetermined area on both sides of each structural joint. 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 also be provided in the critical building finger area, again preferably on both sides of each building joint.
  • the shear-soft composite area is advantageously realized as a soft adhesive layer.
  • a permanently plastic adhesive layer can be provided or a shear-soft 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 fingers.
  • 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 3 for insulating and sealing Fingen building facades comprises an insulation top layer structure 1 with an outer skin or a top layer 2 and an inner insulation 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.
  • an insulation cover layer structure shown in FIGS. 1 to 4 measures are taken in the insulation 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 outer skin 2, is not damaged.
  • Fig. 1 it is provided for this purpose that the insulation layer 3 on both sides of the building joint 4 with a width of 10/2 each is not connected to the substrate 5.
  • the resulting composite-free area 6 can optionally also comprise a separating layer.
  • the composite-free area 6 is advantageously realized by not coating the substrate 5 with adhesive in an area of the total width 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 of width l0 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 relative to the concrete base 5, similar to that in 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 l0.
  • the decoupling areas 6a and 6b like the decoupling area 6 in FIG. 1, can be designed as a composite-free or composite-soft zone.
  • the composite layers 6a and 6b can optionally be fiber or mat-reinforced. Such reinforcement can also be provided for the composite layer 6 of FIG. 1.
  • the outer skin or the covering layer 8 of the insulating covering layer structure 1 is designed to be elastic, namely 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 is preferably reinforced with mats or fibers.
  • the material for the particularly stretchable area 8 is 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.
