Definitions

  • the invention relates to an insulation element, in particular for thermal insulation of building facades and for use in composite thermal insulation systems, consisting of a plate-shaped element made of aerated concrete.
  • Insulation elements are known in a variety of designs. You can out Mineral fibers, rigid foams consist and single-layer or multi-layer Have structure. Such insulation elements are, for example used for thermal insulation of building facades. in this connection the insulation elements are part of thermal insulation composite systems. As part of the composite thermal insulation systems, the Insulation elements glued to a supporting surface and if necessary additionally secured by insulation holder with inserted dowel. Here, systems are known which are made exclusively by insulation holders are fixed. In other thermal insulation composite systems, the insulation layer held by rails which cut into the side surfaces Grip grooves. The rails are screwed in and into the load-bearing surface recessed dowels held.
  • a two-layer coating is applied to the surface of the insulation elements
  • Plaster applied which consists of a base plaster, in the one Reinforcing fabric is embedded.
  • There is a finishing coat on the base coat applied which represents the outer surface of the facade insulation.
  • the fabric can be installed in the base plaster throughout.
  • polystyrene rigid foam panels are used as insulation elements. These rigid foam panels have a low bulk density between 15 and 30 kg / m 3 , so that this results in a low weight, which simplifies the processing of these insulation elements.
  • these polystyrene rigid foam panels have mechanical strength properties that provide the necessary transverse tensile strength and the necessary shear modulus in sufficient size for thermal insulation composite systems.
  • the polystyrene rigid foam sheets are stable and essentially unchangeable even when exposed to moisture.
  • the low thermal conductivities of the polystyrene rigid foam panels result in very high thermal resistance, which enables such rigid foams to be classified in the thermal conductivity groups WLG 035 and 040 according to DIN 4108 and DIN 18165, Part 1. Furthermore, there is the possibility to fix the polystyrene rigid foam panels of the thermal insulation composite system with only partial gluing to the building exterior facade by means of appropriate elasticization of the rigid foams and due to the good mechanical properties, so that positive properties of such a thermal insulation composite system with regard to what can be achieved Soundproofing are possible.
  • thermal insulation systems with polystyrene rigid foam panels are combustible, so that they are only classified as flame-retardant in building material class B1 according to DIN 4102, Part 1.
  • Thermal insulation composite systems based on polystyrene hard foam panels can burn relatively easily with the insulation thicknesses common today, especially more than 8 cm, from the normally unsecured openings (windows, doors) in the insulated wall surfaces or from the base. Nevertheless, approximately 90% of the thermal insulation composite systems produced annually are based on polystyrene rigid foam.
  • Non-combustible mineral wool insulation boards have proven to be an alternative to polystyrene rigid foam boards.
  • the mineral wool insulation panels In comparison to the polystyrene rigid foam panels, however, the mineral wool insulation panels have lower strength properties, so that the mineral wool insulation panels must be processed and reinforced accordingly. To compensate for the weakening of the surface hardness associated with this, plates made of calcium silicate, fiber cement or aerated concrete are glued to the mineral wool insulation layer or fastened with insulation holders.
  • Aerated concrete is admittedly an insulating layer suitable for composite thermal insulation systems, since, for example, the thermal coefficient of linear expansion is low and therefore cannot cause cracking in the plaster, the usual bulk densities of more than 400 kg / m 3 and the thermal conductivity of more than essentially 0.10 W / mK make the processing of such aerated concrete slabs cumbersome, since extremely thick insulation layers have to be applied in order to achieve adequate thermal insulation.
  • these thick layers of insulation lead to a high weight of the thermal insulation composite system, which is disadvantageous on the one hand during processing and on the other hand causes high stress on the connecting means between the facade and the thermal insulation panels (cf. WO 95/11 357 A or DE 2 854 228 A).
  • the aerated concrete slabs have the disadvantage that they have only one have low breaking strength, so that edges break off easily and the surfaces are not resistant to abrasion. At the construction sites prevailing working conditions are therefore large quantities of cellular concrete insulation panels damaged, which is then disadvantageous for the thermal insulation composite system impact if these damaged insulation boards installed become.
  • the invention has for its object to develop an insulating element of the generic type such that the disadvantages described above can be avoided.
  • the solution to this problem provides for an insulation element of the generic type that the plate-shaped element made of aerated concrete with a bulk density of 75 to 250 kg / m 3 and a thermal conductivity between 0.030 to 0.050 W / mK, whose at least one large surface with a strength-increasing and adhesive coating is provided.
  • Such an insulation element is particularly suitable for composite thermal insulation systems suitable, the relatively low bulk density a simplification the processing of the insulation elements and the requirements the adherence of the lanyard to be applied to the facade reduced. Furthermore, the strength-increasing and adhesion-promoting Coating on at least a large surface of the plate Elementes the insulation element so strengthened that a higher abrasion resistance and a higher breaking strength of the edges of the insulation element be achieved.
  • the plate-shaped element made of aerated concrete has a bulk density of 100 to 150 kg / m 3 .
  • Suitable coatings can be made from plastic-containing construction adhesives, for example on the basis of hydraulically setting cements consist. Resin plasters are also suitable.
  • the surfaces of the plate-shaped element are included Deep reasons based on acrylates, butadiene-styrene copolymers and similar saponification-resistant plastic dispersions or solutions stabilized. Because these substances are negative They may have an impact on the building material class covered with layers of adhesive and mortar.
  • the thickness of the coating is kept as low as possible for reasons of weight. It has proven advantageous to coat with a thickness of less than 5 mm.
  • the coating can consist of silica, the so-called Ormocere is applied via nanotechnology and essentially solidifying in the areas below the surface acts. Furthermore, they are coated with silica sol, water or aluminum phosphates bound mixtures of minerals doped with plastics such as quartz sand, aluminum hydroxide and the like. Here is just to ensure that minerals are excluded that are under Swell up moisture.
  • Lattice fabric for example made of glass fibers, aramid or Carbon fibers, cellulose fibers or the like on one or both large surfaces of the plate-shaped element embedded in the coating or glued on with their help.
  • the insulation element has recesses, in particular Holes for the insulation holder.
  • These holes are, for example according to one in the admission requirements for the Thermal insulation composite system or dowel pattern matched to the board size arranged.
  • Usual insulation holders are in the transition from the shaft extended to the flat holding plate frustoconical, so that it turns out to be advantageous has proven that the bores are also frustoconically enlarged, so that notch stresses when inserting the insulation holder be avoided.
  • the holes also serve as a drilling aid, so that When drilling on the construction site, the holes are widened by inclined Starting and subsequent correction can be avoided.
  • the plate-shaped elements made of aerated concrete are indeed high Dimensional accuracy can be produced, but cannot necessarily avoid laying joints.
  • Such installation joints are usually according to the state the technology for polystyrene rigid foam panels with polyurethane foam closed near the surface.
  • this procedure represents an additional one Step that is time-consuming and therefore costly.
  • Around Avoiding disadvantages is with the insulation elements according to the invention provided that on at least one narrow side of the plate-shaped Element of a mineral wool strip is arranged.

  • a material thickness between 5 and 50 mm, preferably less than 15 mm has proven to be advantageous for mineral wool strips.
  • Thermal insulation composite systems with the insulation elements according to the invention can also have a rail system, which the insulation elements hold on the facade.
  • a rail system which the insulation elements hold on the facade.
  • at least two, in particular parallel narrow sides of the have plate-shaped elements grooves, which are preferably sawing in the plate-shaped element are introduced. These grooves can then be used accordingly trained elements of the rail system intervene to the To hold insulation elements on the facade.
  • the grooves are preferably 1 to 3 mm high and 5 to 20 mm wide.
  • a compressible mineral wool insulation board or a mineral wool insulation felt is arranged.
  • This configuration has been particularly useful when using the invention Insulation boards in composite thermal insulation systems with rail systems reinforced.
  • the insulation boards are fastened with rails in usually on uneven surfaces, whereby these unevenness through the Rails or washers are balanced under the rails. With such conditions, the insulation boards are within a certain range Distance from the facade, so that between the facade and the Insulation boards form a cavity. Such a cavity or several such cavities allow air to circulate so that a clear one Reduction in the thermal resistance is recorded.
  • the mineral wool insulation board has proven advantageous for this or the mineral wool insulation felt with a material thickness of 10 to 50 mm train.
  • the cavities are then maximally closed, if the mineral wool insulation board or the mineral wool insulation felt the Cover the entire surface of the plate-shaped element. It exists but also the possibility that on the surface of the plate-shaped element the mineral wool insulation board or the mineral wool insulation felt over part of the surface is applied, with a strip-like configuration of this Has proven beneficial.
  • These are preferably mineral wool strips all around or parallel to the long sides or as a single Sealing strips arranged.
  • the mineral wool insulation board or the mineral wool insulation felt with cutouts for receiving an adhesive element train preferably forms in the hardened state a spacer.
  • This spacer can withstand pressure and prevents that the insulation board breaks through under external pressure. Farther the spacer increases in conjunction with an insulation holder Stability of the thermal composite system.
