Definitions

  • the invention relates to a multilayer composite panel according to the preamble of patent claim 1.
  • the invention further relates to a multilayer board with a closure for connecting composite boards according to claim 7 or claim 13.
  • Panels for cladding facades are already known. Most of these panels consist of a metal weatherproof cover layer and an insulation layer inserted between the facade and the cover layer. The exact laying of such panels is complex, because the insulation layer, which is usually made of very soft and brittle foam, has to be applied to the facade and then the non-dimensionally stable top layer has to be laid over it.
  • a closure for connecting wall cladding panels is known from the Dutch patent application 77 11 222.
  • the closure of the plates is produced by deforming the side edges of the cover layer into a hook-shaped profile, which forms a connection with the profile to be located next to it.
  • the two profiles lie flat on top of each other and thereby allow water to penetrate through the closure to the rear of the same on the facade or on an insulating intermediate layer.
  • DE-PS 25 21 590 describes a further heat-insulating plate, the heat-insulating layer of which is also covered at the edges by the cover layer. On two opposite sides, the edges in the plate center plane are designed as a tongue and a groove.
  • edges In the case of joined panels, the edges also lie flat on one another in this embodiment or form a parallel dilatation gap through which water can easily penetrate and destroy the insulation.
  • the object of the invention is now to create a facade cladding system in which the individual element panels form a dimensionally stable unit, the surface of which, regardless of the strength and thickness of the cover layer, can be adapted to the requirements imposed by the respective environment and to a - swell-proof Area can be joined together.
  • the object of the invention is further to increase the outer surface of the plate, in particular when aluminum is used as the cover layer, its mechanical properties with regard to sound insulation, pressure and impact resistance and elasticity.
  • Another object of the invention is to profile the top layer at the edges and to reinforce it by the plate structure, so that after the assembly they claw into one another that on the one hand the thrust forces and movements resulting from dilation and the forces generated by wind are absorbed can as well as the building physics requirements with regard to water vapor diffusion are guaranteed.
  • the invention solves these problems by means of the multi-layer board according to the characterizing features of patent claim 1 and a multi-layer board with a closure on the cover layer of the multi-layer board according to claims 7 and 13.
  • the panels can also be installed by auxiliary personnel without any problems. Assembly errors that would prevent rear ventilation are excluded.
  • the panel edges which are completely adjacent to each other at the joint, are barely noticeable and form an aesthetically pleasing facade.
  • the composite layer 5 creates a permanent connection between the construction layer 3 and the cover layer 7; it also serves to improve the mechanical properties of the cover layer 7, in particular to increase its impact resistance. It also serves to form thermal insulation between the cover layer 7 and the ventilation channels 9 embedded in the construction layer 3 in order to prevent the formation of condensation on the outside in certain extreme climatic conditions.
  • the ventilation channels 9 run essentially parallel to the edges 11 and 13 of the plate 1.
  • channels 9 instead of channels 9, however, other shaped cavities can also be provided.
  • the edge 11 as well as the edge 13 are produced by deforming the edges of the metal cover layer 3 in one continuous operation. On the one hand, they form the closure parts between rows of plates 1 and, on the other hand, serve to increase the dimensional stability of the cover layer 3.
  • the edge 11 is designed as a tongue 12, the edge 13 as a groove 14, which, when pushed into one another, is elastically yielding in the longitudinal direction, but through Storm winds and similar influences form an inseparable connection.
  • the top layer 3 is visible at the top.
  • the cover layer 3 is bent as edge 11 and 13 from the plane A.
  • the bent surface 17 extends at an angle ⁇ of 75 ° to 90 ° to the plane A.
  • the surface 17 is adjoined by a section 19, again essentially parallel to the cover layer 3, which also has a bead lying parallel to the edge 13 21 can be provided.
  • a deflection 23 of the edge adjoins section 19.
  • the deflection 23 can have a constant radius R, it can also take place in two parts and be interrupted by a flat intermediate web 25 (FIGS. 3 to 6).
  • the deflection 23 is followed by a section 27 that is essentially parallel to the plane A and ends in an edge 29 parallel to the joint 15.
  • the edge 29 can be designed as a bead 30 and, if necessary, can be provided with an elongated web 32 (FIG 2); however, it can also form an edge 28 which runs essentially at right angles to section 27 (FIG. 3).
  • the edge 11 forming the spring 12 on the side of the plate 1 opposite the edge 13 also has a surface 31 running at an angle a of 75 ° to 90 ° to the plane A. This is adjoined by a section 33 lying essentially parallel to plane A, which - when the tongue 12 is pushed into the groove 14 - comes to rest under the section 19.
  • the edge 35 of the section 19 is bent downward and approximately so long that it ends at the foot of the bead 30 or the bent edge 28.
  • the angle ⁇ between the section 33 and the edge 35 can be in the relaxed state, i.e. if panels 1 are not joined, be slightly larger to ensure that they interlock.
  • the section 31 can, as FIG. 8 shows, be angled or have a recess 37 (FIGS. 2, 3, 6, 9), a bead 39 (FIGS. 4.7), with between the recess 37 or the bead 39 and the Level A of the cover layer 3 is a narrow parallel band 38 of the sections 17 and 31 is possible (FIGS. 3 to 9) in order to prevent a displacement of the adjoining surfaces of the cover layers 3.
  • a bead 41 can also be embossed in section 33 of the edge 11 (FIG. 9), in order to form cavities between the opposite sections of the edges 11 and 13, which enable any contact through the contact areas of the edges 11 , 13 swelling water (capillary action) which has penetrated at the joint 15 or on the belt 38 is discharged or its further penetration to the construction layer 3 is effectively prevented.
  • a section 8 of the cover layer 7 is angled substantially perpendicular to the plane A.
  • the construction layer 3 may end flush at the deflection 23, shown in broken lines in FIG. 3, or may extend as far as the edge 29 (FIG. 1) and consequently rest against the construction layer 3 of the adjacent plate 1 in the case of joined plates 1.
  • the construction layer 3 reaching to the edge 29 serves to increase the strength of the groove 14.
  • Figures 10 to 13 show grooves 14 and tongues 12, which are slightly V-shaped and have no edge 30 designed as a bead 29, which imposes the two plates 1 on each other.
  • Figures 10 and 11 is the Edge 14 forming groove 14 essentially perpendicular to cover layer 7 and then has two legs 50, 51 standing in a V-shape with respect to one another.
  • the edge 11 forming the tongue 12 has two legs 52, 53 running essentially parallel to the legs 50, 51 of the groove 14, a bead entering the edge 11 running between the edge 11 and the leg 52 in the embodiment according to FIG 54 is provided.
  • the legs 50, 52 run essentially parallel to the cover layer 7.
  • the composite panels according to FIGS. 12 and 13 have, like those according to FIGS. 10 and 11, legs 50, 51 and 52, 53 which run in a V-shape. However, they differ in that the two legs 51, 53 are arranged essentially parallel to the cover layer 7.
  • the plates 1 are usually struck vertically on the masonry 43 with brackets 45.
  • the clamps 45 encompass the edge 29 or the bead 30 and hold the plate 1 against the masonry 43.
  • the construction layer 3 then lies snugly on the substrate or masonry 43.
  • the bent end 47 of the bracket 45 serves as a barb for the edge 35 at the edge 11.
  • a comb 49 can be provided on the bracket 43 as an additional safeguard against sliding apart of two hung plates 1.
  • the dilation of the panels 1 in the longitudinal direction is retained by the clamps 45, because no screws or rivets rigidly connect the panels 1 to the masonry 43. This results in neither forces in the plate 1, which can lead to "constraints" or bending of the plate 1, nor forces that act on the wall and the fastening elements.
  • the top layer has the task of protecting the panels and the underlying substrate from the weather.
  • Mainly cold-profiled materials such as painted aluminum sheet, steel sheet and non-ferrous metal sheets with a material thickness of 0.5 to 1 mm can be used as the covering layer.
  • the composite or The intermediate layer has the task of connecting the cover layer with the construction layer and adapting the physical properties of the cover layer with regard to mechanical influences to the conditions of the environment.
  • the hardness of the composite layer can be higher than that of the cover layer, but it can also be very elastic.
  • Suitable materials are high-density PU (polyurethane) adhesives or foams, epoxy adhesives or foams with inlays of glass mats or similar reinforcement products.
  • the layer thickness of the adhesive is in the range from 0.5 to 2 mm, that of the foams from 3 to 15 mm.
  • a hard plate e.g. stable coated on both sides with adhesive, e.g. made of a thermosetting plastic, in order to make the top layer particularly heavy-duty at high-stress points (e.g. plinth areas on facades).
  • the construction layer has the function of
  • the known insulating materials such as polystyrene hard foam, PU foam, mineral wool with a density of approx. 100 kg / m 3 , wood products, cork and foam glass are suitable as materials.
  • connection between the different layers can be "cold” or in an oven.
