Definitions

  • the present invention relates to a system for fixing cladding panels in or on buildings, such as insulating panels, in particular thermal insulation panels, e.g. for exterior wall, interior wall, ceiling and / or roof insulation.
  • buildings are constructed in such a way that their walls have minimal thermal conductivity.
  • components made of porous building materials are usually provided.
  • thermal insulation of new and old buildings is usually applied to a masonry first a thermal insulation board, in particular expanded polystyrene foam, mineral wool or stone wool lamella.
  • the cladding panel can be connected to the wall according to a conventional attachment method by means of an adhesive, for example by means of a foam adhesive, such as in the EP 1 039 058 A1 disclosed.
  • Adhesive foams such as those based on polyurethane, are used as permanent, non-positive connection material for adhesive bonding of insulating boards.
  • Polyurethanes adhere perfectly to almost all substrates found in construction. They are easy to process, tough, elastic and transfer thrust and Tensile forces reliable even under thermal influences.
  • polyurethane monomers and oligomers can be crosslinked with water to form an inert, durable plastic.
  • the disadvantage here is that the isocyanate group hardens with water in a condensation reaction with elimination of gaseous carbon dioxide to form a polyurea.
  • the formed carbon dioxide drives the, in this phase still plastic, adhesive on and leads to an expansion of the adhesive layer.
  • This unavoidable reaction / expansion causes bonded components usually to change their intended position, if they are not at least temporarily mechanically fixed.
  • self-foaming adhesive foams have the disadvantage that the glued cladding panels press off in an uncontrolled manner from the substrate due to a post-expansion of the adhesive foam applied between the cladding panel and the substrate.
  • the glued cladding panels press off in an uncontrolled manner from the substrate due to a post-expansion of the adhesive foam applied between the cladding panel and the substrate.
  • the inconsistent nature of the substrate it may be that adjacent cladding panels are no longer aligned flush and no longer parallel to the substrate after curing of the adhesive foam.
  • the EP 1 640 521 A1 solves this problem by means of angle-shaped fasteners, wherein a leg is glued to the wall, while the second leg is fixed with pins on the insulation board.
  • a prior custom design of the insulation board is necessary because the insulation board for receiving the angle leg must have a gradation in the top of the plate.
  • the thickness of the fixing would build inadmissible and the resulting gaps would lead to thermal bridges, as well as, for example, let a subsequent reinforcing material impermissibly penetrate deep into the gaps.
  • caused by the multiple gradation of insulation boards compared to conventional standard plates increased costs in the production.
  • due to the only one-sided Jardinnfalze the multi-layered insulation boards are only horizontally applicable and in exact pass sequence.
  • a further disadvantage of the prior art is that once fixed cladding panels are no longer displaceable, i. the position of a plate, once fixed to the wall with the angle, can not be corrected.
  • a further adjustment is the rule, even if several horizontal layers have already been applied one above the other.
  • the underlying object of the present invention is to overcome the disadvantages of the prior art.
  • a system for attaching trim panels to a base e.g. additionally to be fixed by means of an adhesive to the pad, sought, which allows a simple and inexpensive prefabrication of the components, which is applicable to different types of standardized cladding panels and is easy to implement on the site.
  • the fastening system should be a e.g. prevent positional change of the trim panel on the base caused by expansion or movement of an adhesive.
  • the present invention solves this problem by providing a method for fixing a cladding panel on a substrate, in particular for insulation, particularly preferably for thermal insulation on and / or in a building or on a building part.
  • the system or method according to the invention can be applied both to the mounting of cladding panels on the outer walls of buildings and mobile rooms, as well as to (interior) walls and ceilings in buildings and mobile rooms, as well as to components that are part of a building or a mobile Room should be joined together.
  • the application of cladding panels on roofs of buildings or mobile spaces is conceivable.
  • an outer wall, inner wall, ceiling, or a roof surface can be understood.

  • the pad may be uncoated or coated, for example, with plasters, paints, varnishes, primers, etc., or combinations thereof.
  • Core of the invention is, inter alia, that due to the frictional engagement, preferably the clamping between the recess laterally delimiting surfaces and the opposite lateral surfaces of the fixing a displaceability of the fixing along one or even two dimensions without loss of connection of the fixing is made possible with the cladding panel , Especially after the attachment of the fixing element to the pad.
  • the fixing element is thus inserted into the recess until frictional contact of the said lateral surfaces of the fixing element with the said lateral surfaces of the recess is achieved. Due to the preferably elastic deformability of the material, the fixing element is preferably clamped in the recess.
  • deformability is meant that the fixing element is not easily displaced in the recess without a substantial force.
  • the frictional engagement or the clamping is produced by an elastic deformation of at least one of the two surfaces or components involved in the frictional engagement.
  • the fixing can be pulled under force in a controlled manner depending on the desired distance of the cladding plate from the pad into the recess or further out of the recess, and preferably also be moved in a direction parallel to the pad, but it always remains frictionally attached.

  • the fixing element 4 is a certain play or a gap 12 is available, which allows a displacement of the fixing element 4 in the recess 3 in a direction transverse to the base 2.
  • the width b1 of the fixing element 4 used ie the distance from the one laterally delimiting surface 4c in the transverse direction Q, to the opposite delimiting surface 4d of the fixing element 4, is in the range of 16-26 mm.
  • the height h1 of the fixing element 4 is in the range of 27-54 mm.
  • the length 11 of the fixing element 4 is in the range of 40-120 mm.
  • the width b3 of the recess is 0.5-3 mm smaller, in particular in a range of 1-1.5 mm smaller, formed as the width b1 of the fixing, as well as in Fig. 1 shown.
  • the fixing element 4 is clamped in its first region 4e in the recess 3 at least on the two surfaces 4c, 4d which lie opposite one another in the transverse direction Q. Under clamping here is at least the presence of a frictional connection to understand.
  • the fixing element 4 is thus displaceably mounted in the recess under force. So that the fixing element 3 with its greater width b2 can be inserted into the recess 3 at all, the fixing element 4 and / or the lining plate 1 is at least partially deformable or elastically deformable.
  • the fixing element 4 is not yet introduced into the recess 3.
  • the adhesive layer 5 on the pad 2 facing surface 4b of the pad 2 facing the second region 4f still has a non-adhesive protective layer 5a in order to protect the adhesive layer 5 from drying out and / or to prevent unwanted premature fixing of the fixing elements 4 in undesired positions.
  • the direction of insertion of the fixing block 4 in the recess 3 is shown with a dotted arrow.
  • the dotted arrow shown between the cladding panel 1 and the pad indicates the direction in which the cladding panel 1 is moved toward the wall to effect fixing of the fixing members 4 by means of their adhesive layers 5.
  • the top 11a of the trim panel 1 is closed in the illustrated embodiment, i. designed without cuts or grooves.
  • Fig. 2 two cuboid Fixierblöcke 4 are shown.
  • the two mutually parallel recesses 3 are formed as straight longitudinal grooves which extend in the longitudinal direction L of the cladding panel 1 to the edge of the cladding panel 1.
  • the Fixierblöcke 4 are also not used according to this illustration to the bottom 3 c of the longitudinal groove 3 in the respective longitudinal groove 3. This leads to an intermediate space 12 between the bottom 3c of the longitudinal groove 3 and the surface 4a of the fixing element 4 facing the bottom 3c.
  • the two fixing elements 4 shown protrude beyond the edge of the lining panel 1 in the groove running direction R1.
  • the fixing elements 4 protrude in a direction perpendicular to the Nutverlaufsraum R1 and perpendicular to the pad 2 on the surface facing the pad 11 and out of the longitudinal groove 3 out.
  • the two fixing blocks 4 are shown here without an adhesive layer 5.
  • Fig. 3 is a cladding panel 1 of rectangular outline according to a preferred embodiment of the bottom, ie, with respect to the bottom 11 b, shown. This has two parallel to each other, over the entire length 12 of the cladding panel 1 extending deep cuts 6, and two parallel over the entire width b2 of the cladding panel 1 extending deep cuts 7.
  • an incision 6 intersect in the longitudinal direction L of the cladding panel 1 with two incisions 7 in the transverse direction Q of the cladding panel 1 and vice versa.
  • the incisions 6, 7 serve the deformability of the material.
  • due to unevenness of the pad as well as eg due to installation-related Stresses occurring gaps, especially in Nutverlaufsraum or assembly direction avoided.
  • Fig. 4 are, in a view from the base 2 forth on the bottom 11b and in the longitudinal grooves 3 inside, two facing panels 1 a, 1b shown with such longitudinally extending L incisions 6 and in the transverse direction Q of the cladding panel 1 extending incisions 7.
  • the cladding panels 1 are narrower, ie formed with a smaller length 12 than in the embodiment of Fig. 3 ,
  • Cladding panel 1a shown on the left is the cladding panel to be mounted or mounted beforehand. Since no further cladding panel 1 adjoins it to the left, the two fixing elements 4 do not protrude beyond the illustrated left edge of the cladding panel 1 a, but are received completely in the longitudinal groove 3 with respect to their length 11. However, two fixing elements 4 are arranged on the side 8 to be fastened next to the facing panel 1 b, which stand out beyond the edge of the first panel 1 a mounted. Due to these two protruding fixing elements 4, the in Fig. 4 shown on the right, next to be fastened trim panel 1b are pushed onto the protruding portions of the two already firmly attached to the wall fixing elements 4. This second cladding panel 1b in turn has two projecting fixing elements 4 on its side facing the next cladding panel to be mounted.
  • the position of the second trim panel 1b can then be adjusted to the position of the first trim panel 1a.
  • the fixing element 4 is thus both in a direction perpendicular to the base 2, as well in Nutverlaufscardi R1 slidably mounted in the groove 3.
  • the second or further following cladding panel 1 b can be adjusted to the previous, until the edges and surfaces with those of the previously mounted cladding panel 1a are flush.
  • the fixing element 4 has clearance 12 in the groove 3, ie it does not necessarily have to touch the bottom of the groove 3 in the final position of the cladding plate 1, which is between the surface 4a of the fixing element 4 facing the bottom 3c of the groove 3 and the bottom 3c of the groove 3 leads to a gap 12.
  • each fixing element 4 is covered by a hatched adhesive layer 5, which serves the cohesive connection of the fixing element 4 on the base 2.
  • fastening system is the cladding panel 1 by means of fixing blocks 4 as well as by means of an adhesive 10, or a foam adhesive, attached to the pad 2.
  • Both the adhesive 10 between the cladding panel 1 and the pad 2, as well as the adhesive layer 5 between the fixing elements 4 and the pad 2 provide a cohesive connection.
  • the adhesive 10 when a foam adhesive or adhesive foam is used as the adhesive 10, it expands after application to the trim panel 1 or to the base 2 until it cures, which can lead to a pressing of the trim panel 1 of the pad 2.
  • the attachment of the fixing elements 4 to the trim panel 1 withstands this propulsion pressure.
  • an expansion of the adhesive foam 10 beyond the desired position is prevented by the frictional engagement or the clamping action between two opposing surfaces 4c, 4d of the fixing element 4 and two opposing surfaces 3a, 3b of the groove 3.
  • the trim panel 1 is prevented from changing its relative position to the base 2 and / or the adjacent trim panels 1, the distance A2 between the trim panel 1 and the base 2 being large enough to allow some expansion of the foam adhesive.
  • This distance A2 can be selected during assembly of the cladding panels 1 and even after the attachment of the fixing elements 4 on the pad 2 can be set later.
  • FIG. 6 For example, a selection of different possible floor plans for fixing elements 4 are shown schematically in a plan view, wherein other shapes are possible, which could offer any material-dependent or construction-specific advantages.
  • FIG. 6a the square outline of a cubic Fixierblocks 4 is shown while Fig. 6b a round outline of a cylindrical Fixierblocks 4 shows.
  • Fig. 6c shows a triangular floor plan, Fig. 6d a rectangular plan of a cuboid fixing 4.
  • Fig. 6e is a dumbbell-shaped floor plan, and in Fig. 6f a polygonal plan view of a polyhedral fixing element 3, while in Fig. 6g a substantially cross-shaped floor plan is shown.
  • the fixing elements 4 may also have additional structures on their periphery, e.g. Grooves, incisions, notches, or widened or tapered areas, etc. have.
