Definitions

  • the present invention relates to a thermal insulation composite system according to the preamble of claim 1.
  • EP 1 088 945 A2 discloses an insulating element, which is provided with markings which are formed as depressions, in which the plate dowels are sunk.
  • markings which are formed as depressions, in which the plate dowels are sunk.
  • a local destruction of responsible for the transmission of shear and tensile forces surface is particularly associated with insulation elements of mineral wool, which are in thermal insulation systems as wind suction forces from a static point of great importance.
  • At the outer edge of the depression stress peaks occur, which can accelerate a tearing off of the insulating material.
  • closure body are glued into the recesses in particular with its lateral surface, so that again a continuous frictional surface is produced.
  • the disclosed design of the marking aids as wells can bring another problem.
  • each depression is accompanied by a structural weakening of the insulating elements, which must be compensated by an inserted and bonded closure body.
  • the plate dowels are mounted on the basis of conventional mounting patterns in practice, with spatially closer to building corners and edges lying insulating elements are attached with a larger number of plate dowels.
  • a large number of different insulating elements can result from this with predetermined depression patterns, which leads in practice to increased logistics costs.
  • the EP 1 088 945 A2 not problems with the cutting of the insulation elements to the given building dimensions.
  • the object of the invention is to develop a thermal insulation composite system so that the disadvantages described are avoided, and the use of Insulating elements with lower thermal conductivity and reduced mechanical strength is possible.
  • the solution to this problem provides a composite thermal insulation system with an attached to a building wall insulation layer of mineral wool insulation elements, which are mounted in the insulation layer recessed plate dowel in the form of a unit of plate and shaft on the building wall, the insulation layer areally with at least one reinforced plaster layer is covered.
  • a free space completely filling plug of mineral wool with a sufficient resistance to tear is used for substantially removing the wind suction forces, which is glued to the plate of the anchor by means of an adhesive.
  • insulating elements made of mineral wool in particular insulating elements made of stone or glass wool are used.
  • the wind suction forces acting on the reinforced plaster layer are essentially statically reliably discharged into the building wall in the long term via the plugs glued to this layer via the plate dowel.
  • the elements of the wind suction forces which are still to be transmitted via the insulating elements are thus substantially reduced, so that lower demands can be placed on the mechanical breakaway strength of the insulating element used than in the past.
  • This now possible reduction of the mechanical requirements allows the use of heat insulation from advantageous insulating elements with a lower thermal conductivity.
  • This allows in particular the use of mineral wool insulation elements with a thermal conductivity corresponding to the heat conduction group 035.
  • the adhesive should preferably have a strength which is greater than the tear-off strength of the plugs for fastening the plug to the plate of the plate dowel after it has hardened.
  • the adhesive has such a fluidity that it rests positively after insertion of the plug on the plate and the bottom-side main surface of the plug, and the connection after Curing of the adhesive is non-positive. This ensures that the adhesive can reach the undercut recesses in the liquid state by the introduction of the plug into the free space of the recess through the openings of the plate, so that after its curing said positive and non-positive connection between anchor plate and plug results.
  • the adhesive can be applied to the plate after inserting the dowel.
  • the adhesive can also be applied to the bottom of the depression before the introduction of the plate anchor.
  • the tear resistance of the plug of mineral wool is greater than or equal to the tear resistance of the insulating elements, but at least 15 kPa.
  • the depressions can be introduced by drilling or milling in the insulation elements.
  • this introduction of the recesses takes place directly on site during the attachment of the insulating elements to the building wall, so that a pattern corresponding to the usual mounting patterns can be used.
  • the number of plate anchors can be limited to the minimum required for a long-term statically safe power dissipation.
  • the diameters of the depressions at the bottom of the depression are 100 to 150%, preferably 100 to 120%, particularly preferably 100 to 105% of the diameter of the plate.
  • a smaller diameter of the recess than the diameter of the plate is disadvantageous in terms of the introduction of the plate dowel in the recess.
  • the available for the power transmission cross-sectional area can be reduced because, although the dowel plate can be introduced, but the plug tends to tilt and hook over its lateral surface during installation. By this effect, it can happen in edge areas that material of the insulating elements passes between plug and plate, which due to the reduced positive surface between the plate, adhesive and grafting the frictional connection can be directly affected.
  • the area available for power transmission results from the plate diameter. Much larger diameter of the recess and thus of the recess with the positive plug on the plate facing surface are ineffective in terms of power transmission and even disadvantageous in terms of thermal insulation, since the plug have a higher thermal conductivity than the surrounding insulating elements.
  • the depressions and thus the form-locking plugs can be cylindrical and / or frusto-conical.
  • An undercut design of the truncated cone causes due to the low mechanical strength of the insulating elements no further advantages in power transmission, but in addition to difficulties in inserting the plug the problem described a possible reduction of available for power transmission surface by clamping material of the insulating elements. Therefore, truncated conical shapes with cones open to the outer surface are preferred.
  • the advantages of the truncated cone shape of the recess and the corresponding plug are in the simplified adjustment of the plug in the recess.
  • the area available for the bonding of the reinforced plaster layer with the plugs and stress peaks of the force input are reduced in comparison to the cylindrical design of the plugs.
  • the recesses are better accessible both for the plate dowel as well as for the application of the adhesive.
  • the invention allows the use of plate anchors of the previous standard length, even with increasing insulation thicknesses. This eliminates the need to use multiple plate dowels of different lengths, which would lead to significant cost increases.
  • insulating elements 2 are shown in a free cutting surface of a reinforced plaster application, which are formed as rectangular insulation boards with parallel edges and made of mineral wool with a thermal conductivity corresponding to the bathleiten 035. They are made in a known manner.
  • Each insulating element 2 has two major surfaces, of which in Fig. 1 only the main surface facing away from the building wall 3 can be seen.
  • the insulating elements 2 are arranged in abutment, wherein the rows are arranged offset to avoid continuous vertical shocks. This results in the surface of a brick pattern, which is formed by the abutting edges, of which an impact edge 4 is highlighted as an example.
  • FIG. 1 the outside surface of plug 5 of mineral wool, which are positively inserted in recesses 6.
  • plugs 5 hide invisible plate dowels 7 in the form of a unit of plate 8 with undercut clearances 9 and shaft 10 which glued by means of a likewise not visible adhesive 11 on the plate 8 with the bottom of the plug 5 and the shaft 10 with the not visible building wall 3 are connected.
  • FIG.1 drawn two cut lines II - II and III - III, wherein the section line II - II along the abutting edge of the insulating elements 12 and 13 by a plug 14 in an insulating element 15 and the section line III - III along the abutting edge of the insulating elements 13 and 16 by a Graft 17 in an insulating element 18 extends.
  • the depressions 6 are provided in the insulating elements 2 and serve to receive the plate dowel 7, with which the insulating elements 2 attached to the building wall 3 become.
  • the plate anchors 7 are arranged both in the intersections of the abutting edges and within the surface of the insulating elements 2. The abutting edges are thus simultaneously marking aids for the arrangement of the recesses 6, which are preferably introduced at the intended locations in the insulating elements by drilling, wherein the diameter of which is equal to the diameter of the plate 8 of the plate dowel 7. Subsequently, the plate anchor 7 is introduced in a conventional manner and thus the insulating elements 2 attached to the building wall 3.
  • the plugs 5, 14 and 17 each have a tear resistance of 17 kPa in accordance with the introduced in practice strength class "HD", so that all applied to the thermal insulation composite system in the finished state wind suction statically safely initiated over all plugs with subsequent plate dowel 7 in the building wall 3 become.
  • a reinforced plaster layer 1 is applied to the outer surface of all the insulating elements 2 with the plugs 5 inserted.
  • FIG. 1 In the illustrated area of the building wall 3 for statically secure dissipation of wind suction forces two plate anchors 7 per insulation element needed. In the case of insulating elements, not shown here, arranged closer to the edges of the building, the number of plate anchors 7 must be increased to the statically required number due to higher wind suction forces.
  • the Fig. 2 shows a section through the thermal insulation composite according to FIG. 1 along the line II - II.
  • the representation shows as a first embodiment, a cylindrical embodiment of a recess 19 and the associated plug 14 and the in Fig. 1 concealed adhesive 11 and the plate dowel 7.
  • Fig. 1 is below the plate anchor 7, the insulating element 12 and above the insulating element 15 is arranged.
  • the composite plate 8 and shaft 10 plate dowel 7 is firmly anchored on the shaft 10 with the building wall 3.
  • the recess 9 formed by the undercut plate 8 and the bottom of the recess 19 is completely filled with the adhesive 11.
  • the adhesive 11 is about the openings in the plate 8 with the surface and the bottom of the plug 14 in adhesive contact and thus forms a positive and non-positive connection between the plug 14 and plate dowel 7.
  • On the outside of the insulating elements 2 and the plug 14 is finally a applied plaster layer 7, wherein the wind suction forces are essentially derived via plug 14, adhesive 11 and plate dowel 7 in the building wall 3.
  • Fig. 3 illustrated second embodiment along the line III - III differs from the embodiment according to Fig. 2 in that the plug 17 and the associated recess 20 are frustoconical in shape.
  • Fig. 1 is in turn below the local plate anchor 7, the insulating element 16 and above the insulating element 18 is arranged.
  • the diameter at the bottom of the recess designated 20 corresponds to the diameter of the plate 8, the opening angle of the truncated cone is in the embodiment 10 °.
  • a larger surface for attaching the reinforced plaster layer 1 on the plug 17 is available, at the same time possibly occurring stress peaks in the corners of the plug 17 with respect to the cylindrical design of the plug 14 after Fig. 2 reduced.
