Definitions

  • the present invention relates to a facade construction comprising a load-bearing base, an insulating layer of dimensionally stable insulating boards with a flat and load-bearing outer surface and a skin covering the outer skin of the facade construction forming a plate covering of a plurality of plate elements which are attached by means of an adhesive to the insulating layer. Furthermore, the present invention relates to a method for producing such a facade construction.
  • Facade structures of the type mentioned are known in the art in a variety of configurations.
  • cuboid insulation boards are glued with flat and stable outer surface by means of mortar or full surface using a tile adhesive to a stable surface, such as the outer wall of a building.
  • the plate covering is mounted on the outside of the insulating layer, which provides the rain protection, protects against other effects from the atmosphere and against mechanical stress and the outer design is used.
  • a reinforced, flush-mounted plaster is first applied to the insulating layer, which normally has a total thickness between 25 and 35 mm. On the flush can then be glued the plate elements using a cementitious tile adhesive.
  • a decoupling mat using cementitious tile adhesive is first attached to the flush, which can be additionally secured with dowels, after which the plate elements are glued to the decoupling mat.
  • the decoupling mat serves to prevent transmission of voltages from the flush to the plate elements or from the plate elements to the flush.
  • the plate covering is mounted using metal support systems which are dowelled to the load-bearing surface of the facade structure, the individual plate elements being fixed to the support system by means of special anchors.
  • An advantage of such support systems is that they are mounted at a predetermined distance from the insulating layer, so that the plate covering is ventilated.
  • a disadvantage is that the thickness of the Plate elements must be relatively large, if the anchor should engage in slots or holes, which are introduced in the side edges or at the back of the plate elements, see for example the publication DE 40 04 103 A1 , For thinner plate elements retaining clips are usually used, however, which overlap on the externally visible surface of the plate elements, whereby the appearance of the facade construction is impaired.
  • the adhesive is elastic and dot-like or caterpillar-shaped on the plate elements and / or applied to the insulating layer, and that between the plate elements and the insulating layer spacers are provided, which define fluidically interconnected cavities between the individual plate elements and the insulating layer.
  • a significant advantage of the facade construction according to the invention is that the plate elements are attached directly to the insulating layer without the use of an additional support system, which can be dispensed with an armored concealed, resulting in a very simple and inexpensive construction. Furthermore, a decoupling between the insulating layer and the plate elements is effected by the flexible adhesive. Thanks to the use of spacers, a good ventilation of the plate covering is also achieved.
  • the insulation boards are provided on their front and / or on their back with a fabric or nonwoven coating.
  • a fabric or non-woven is to the effect of advantage that an adhesive or mortar with which the insulation boards are attached to the load-bearing surface of the facade construction, can very well dig into this, whereby a very stable attachment of the insulation boards can be achieved.
  • a stiffening and / or sealing layer is arranged directly below each fabric or nonwoven coating, which may have a paper layer and / or a plastic layer and / or a metallic layer, such as an aluminum foil.
  • a stiffening and / or sealing layer acts to delay the Against insulation boards and / or penetration of moisture or steam.
  • existing joints between adjacent insulation boards are watertight sealed.
  • spreadable and / or fillable sealants in which a fleece or fabric is embedded are suitable for a watertight seal.
  • sealing tapes with double-sided fleece lamination can be used for sealing.
  • a completely waterproof insulating layer is achieved in this way.
  • the plate elements are preferably made of ceramic, natural stone, metal, glass or plastic.
  • the panel members according to an embodiment of the present invention have outer dimensions of at least 40 x 40 cm, resulting in a very attractive visual appearance of the facade construction.
  • the elastic adhesive with which the plate elements are attached to the insulating layer is advantageously a cement-free adhesive, whereby the efflorescence mentioned above are prevented.
  • the adhesive is a silane-modified polymer-based adhesive.
  • Such an adhesive is particularly suitable for processing large-sized tiles with external dimensions of at least 40 x 40 cm.
  • the spacers are by strip-shaped mats or Formed plates, which extend below the edge regions adjacent plate elements arranged as well as along the joints between these plate elements and are fixed to the insulating layer, wherein the joints are filled with Fugmaterial.
  • spacers formed and arranged in this way not only serve to place the plate elements at a predetermined distance from the insulating layer, but they also serve as a base for grouting the plate elements and limit the amount of filler material needed to fill the joints. Filling the joints with grout prevents rainwater from entering the facade structure in large quantities. In addition, thanks to the filled joints, a visually appealing appearance is achieved.
  • the strip-shaped mats or plates each have a family of fluid channels extending in at least one direction, which fluidly connect the cavities between the plate elements and the insulating layer.
  • a good ventilation of the facade construction is ensured.
  • two sets of intersecting fluid channels are advantageously provided, whereby errors in the assembly of the spacers are reliably prevented.
  • the strip-shaped mats or plates are provided in the region below the joints on their upper side with recesses for receiving the Fugmaterials.
  • Recesses contribute to the fixation of the Fugmaterials.
  • the strip-shaped mats or plates are provided at least on their underside with a fabric or a nonwoven, in which an adhesive can cling, with which the strip-shaped mats or plates are attached to the insulating layer.
  • the fabric or the fleece prevents filling of the fluid channels with adhesive.
  • the fabric or nonwoven fabric can be anchored to the underside of the strip-shaped mats or panels by means of a suitable adhesive. Alternatively, it can also be laminated or fused during the manufacturing process of the strip-shaped mats or plates with their material.
  • the strip-shaped mats or plates have a width in the range of 3 to 10 cm. Such a width combines proper operation with low cost.
  • the present invention further provides a method for producing a facade structure of the type defined above, comprising the steps of: a) attaching dimensionally stable insulation boards with a flat and stable outer surface to a load-bearing surface of a facade; b) attaching spacers of equal height to the insulation boards such that the spacers project outwardly from the insulation boards; c) punctiform and / or caterpillar-shaped application of an elastic adhesive to the insulation boards and / or the plate elements in areas in which no spacers are arranged in the intended mounted state of the plate elements, wherein the amount of adhesive application is greater than the height of the spacers; and d) bonding the plate elements to the insulation boards by pressing the board elements against the spacers, wherein cavities remain between the board elements and the insulation boards due to the dot-shaped and / or caterpillar-shaped application of adhesive in step c).
  • the insulation boards are preferably fixed in step a) using a mortar, a thin-bed mortar or an adhesive, in particular a silane-modified polymer-based adhesive to the supporting substrate, wherein the mortar, the thin-bed mortar or adhesive punctiform, strip-shaped or full surface on the insulation boards and / or the load-bearing surface can be applied.
  • the insulation boards may alternatively or additionally be fastened with dowels to the supporting ground.
