Definitions

  • the invention relates to a plaster facade with heat-cold insulation panels, on which a mortar plaster layer is applied with the inclusion of a mesh-like fabric, with distributed on the outer surfaces of the heat-cold insulation panels, individual protruding spacer elements are integrally formed and the fabric on these spacer elements is embedded in the mortar plaster layer.
  • the outer walls of buildings are increasingly covered with an insulating layer made of heat-cold insulation boards before the mortar plaster layer is applied.
  • a fabric covering the joints is embedded in the mortar plaster layer.
  • the heat-cold insulation panels are provided with spacers on which the fabric is placed.
  • a base plaster layer is applied, which, while embedding the fabric, connects to the outer surfaces of the heat and cold insulation boards.
  • a final plaster layer or single-layer plasters e.g. B. lime plaster applied.
  • This construction of a plaster facade has the disadvantage that the fabric is embedded fairly close to the outer surfaces of the heat-cold insulation boards in the mortar-plaster layer consisting of the base plaster layer and the final plaster layer. The majority of the thickness of the base plaster layer and the entire thickness of the final plaster layer are therefore not reinforced and retained by the fabric. This build-up of the mortar-plaster layer therefore repeatedly leads to crack formation, particularly in the final plaster layer.
  • a similar structure of a plaster facade can also be found in DE-A-28 42 879.
  • the spacer elements are designed as spacer webs running parallel to one another and molded onto the heat-cold insulation boards. The lifting of the placed fabric from the spacer elements is even more difficult with this design of the spacer elements, since the fabric lies over a large area and the mortar-plaster layer cannot enclose the fabric even less completely. Crack formation cannot therefore be avoided even with this construction of the plaster facade.
  • the spacer elements are designed in height for the thickness of a base plaster layer, that the base plaster layer fills the space between the fabric and the outer surfaces of the heat-cold insulation panels and that the base plaster layer with complete embedding a final plaster layer is applied to the fabric.
  • the fabric is held in such a way that the base plaster layer can be applied through the fabric to the outer surfaces of the heat-cold insulation boards.
  • the fabric is held in the outer end surface of the base plaster and completely embedded when the end plaster layer is applied.
  • the fabric therefore stiffens the base plaster layer and the outer plaster layer to the same extent, in particular when it is provided according to one embodiment that the base plaster layer and the final plaster layer have approximately the same thickness.
  • the spacer elements are designed as elongated knobs which are convexly curved on all sides, then the base plaster pressed into the space between the fabric and the outer surfaces of the heat-cold insulation boards will slightly lift the fabric off the spacer elements, so that it is embedded on all sides.
  • the application of the base plaster layer is not affected by the spacer elements if it is provided that the knobs are aligned with their longitudinal dimension in the longitudinal direction of the heat-cold insulation boards and that the knobs have a height of approximately 5 to 10 mm and a width of approximately 8 up to 10 mm and a length of about 12 to 15 mm.
  • a uniform support of the fabric by the spacer elements can be achieved according to one embodiment in that the spacer elements are arranged in longitudinal rows on the outer surfaces of the heat and cold insulation boards, the adjacent spacer elements in the longitudinal direction by half a division of the spacer elements in the Longitudinal rows are offset from one another.
  • the retention of the base plaster layer on the outer surfaces of the heat-cold insulation panels can be achieved without deteriorating the support of the fabric in that longitudinal grooves, preferably dovetail grooves, are introduced between the longitudinal rows of the spacer elements in the outer surfaces of the heat insulation panels.
  • the thermal insulation factor of the plaster facade can be increased further in that the base plaster layer is designed as an insulating plaster with embedded granules of insulating material.
  • This basic plaster layer which is designed as insulating plaster, can also be used in such a way that the thickness of the heat-cold insulation boards for the plaster facade can be reduced for a specific thermal insulation factor.
  • the strength of the base plaster layer can be improved by including plastic foam particles and / or pearlite or the like as granules of insulation a grain size of less than 3 mm and a volume fraction of more than 50% are used.
  • the pearlite gives the base plaster layer sufficient strength.
  • the insulation granules reduce the weight of the base coat and bring a certain elasticity, so that the likelihood of cracking is reduced even more.
  • a further embodiment provides that heat-cold insulation boards are used in which at least part of the surface of the spacer elements designed as knobs with an adhesive layer, for. B. cement-plastic layer or the like. Is provided.
  • the final plaster layer can be applied in various compositions.
  • knobs 1 and 2 which preferably consists of rigid plastic foam, is fastened to the outer surfaces of the building in such a way that the surface with the spacer elements 11 designed as elongated knobs is directed outwards.
  • These knobs have z. B. a length 15 of about 12 to 15 mm, a width 14 of about 8 to 10 mm and a height 13 of about 5 to 10 mm.
  • the longitudinal dimension 15 of the knobs is directed in the longitudinal direction of the heat-cold insulation boards 10, which are attached vertically with their longitudinal dimension.
  • the knobs are arranged in longitudinal rows, the spacer elements 11 in adjacent rows being offset by half a division of the spacer elements 11 in the rows, as can clearly be seen from the plan view according to FIG. 1. Between the rows of spacer elements 11, longitudinal dovetail grooves 12 are introduced into the surfaces of the heat-cold insulation panels 10.
  • the height of the spacer elements 11, which are convexly curved on all sides, corresponds to the thickness of the base plaster layer 16 to be applied.
  • the fabric 20 with the longitudinal threads 18 and the transverse threads 19 is hung from the heat-cold insulation panels in front of the insulation layer .
  • the fabric covers the joints between the heat-cold insulation panels 10.
  • the base plaster penetrates through the mesh of the fabric 20 and fills the space between the outer surfaces of the heat-cold insulation panels 10 and the fabric 10, it also in the dovetail grooves 12 penetrates and has an excellent hold after setting.
  • the fabric 20 is fixed in the outermost region of the base plaster layer 16, whereby it is evenly supported by the knobs as spacer elements 11.
  • the applied base plaster pushes up on the knobs and lifts the fabric 20 slightly off the knobs, so that it is embedded on all sides in the base plaster layer 16 and the final plaster layer 21 applied later. If the base plaster layer 16 and the final plaster layer 21 have approximately the same thickness, then the fabric optimally stiffens the composite mortar-plaster layer and prevents cracking.
  • the adhesion of the base plaster layer 16 to the knobs can be improved in that at least a part of the surface of the knobs with an adhesive layer, for. B. cement-plastic layer or the like. Is provided.
  • the thermal insulation factor and the breathability can be improved in that the base plaster layer 16 is designed as an insulating plaster.
  • the insulation granules 17 included in the base plaster layer 16 consist of plastic foam particles and pearlite with a grain size of less than 3 mm and a volume fraction greater than 50%.
  • the plastic foam particles give the base coat 16 an elasticity that prevents cracking.
  • the plastic foam particles increase the thermal insulation factor just like the pearlite.
  • the pearlite also provides the base plaster layer 16 with sufficient strength.
  • the final plaster layer 21 can be applied with normal mortar without any plastic content.
  • the base plaster layer 16 designed as insulation plaster brings a substantial increase in the thermal insulation factor, so that the thickness of the heat-cold insulation boards 10 can also be reduced for a specific thermal insulation factor.
  • the proportion of plastic foam particles and pearlite in the mixture for the base coat 16 is approximately the same size.
