Definitions

  • the invention relates to a natural stone composite panel with a natural stone slab, a lightweight material layer and with additional elements to increase strength, as well as a method for Production of a natural stone composite panel.
  • the natural stone composite panel according to the invention is for use as a worktop in high-quality kitchens suitable.
  • U1 is a worktop with a cover layer of natural or Artificial stone and a carrier layer of a lighter material described at the natural stone slab is connected to a carrier layer of calcium silicate.
  • Disadvantages are the low strength of the worktop; in particular the bending tensile load capacity low. The from the low bending tensile load capacity resulting risk of breakage is in areas with weakened cross-sections - such as next to recesses and protruding wheels - especially high.
  • a plate-shaped semifinished product a method for Production of a plate-shaped semifinished product and a trough-shaped object known.
  • the at least a natural stone layer with at least a first and a second side wherein the natural stone layer is connected to a polyurethane molding is, the polyurethane molding is by at least two superimposed lying layers are formed, which removed from the natural stone layer lying layer has a higher strength than the at least one other Layer.
  • the at least one more layer should be the lever arm the internal forces, namely the compressive force in the plane of the natural stone plate and the tensile force in the plane away from the natural stone layer layer with higher strength, increase to increase the recordable moment.
  • this plate-shaped semi-finished is disadvantageous that the bending tensile strength of the entire semi-finished product - which is greater than the flexural strength of the natural stone layer is - by the shear strength of at least one further layer, is limited so that in areas with weakened cross sections - such as Example next to recesses for rinsing - danger of breakage exists.
  • the invention is based on the object, a natural stone slab arrangement and to provide a method of making it, which allows the natural stone slab to perform with a small thickness and still a sufficiently high Biegezugfesttechnik has machined and transported in larger dimensions to be able to.
  • the object is achieved with an arrangement which corresponds to the in Claim 1 features, and with a method which having the features specified in claim 7, solved.
  • the invention has a number of advantages. By arranging a reinforcement with high tensile strength and a very high modulus of elasticity compared to the natural stone slab, a high bending tensile strength is achieved even when using a thin natural stone slab, even without a shear-resistant lower layer.
  • the stiffening allows aesthetically effective design elements to be incorporated into thin natural stone slabs with thicknesses of less than 12 mm.
  • the inventive method for producing thin natural stone slabs is particularly advantageous that by the freezing of a fastening device on flat elements regardless of the roughness and nature of the Surface of the flat elements a secure and virtually noiseless fixing is possible, whereby neither affects the surface texture bending moments are introduced into the planar elements.
  • This makes it possible, in particular, very thin natural stone slabs of natural stone blocks or separate from thicker natural stone slabs.
  • water as a medium for freezing the fastening device the process of the invention can be environmentally friendly without use be carried out by pollutants. It can with this method both Slabs with uneven surface as well as polished surfaces can be processed.
  • a natural stone plate 1 which has a small thickness, by means of a first adhesive layer 2, which is formed as a high-strength Epoxidharzkleb harsh, a carbon fiber reinforcement layer 3 attached. Both the strength and the modulus of elasticity of the reinforcement layer 3 are significantly greater than the strength and the modulus of elasticity of the natural stone slab 1.
  • the reinforcement layer 3 is arranged within a plane, so that due to a moment load of the composite plate no deflection normal to the plane of the reinforcement layer 3 occur. Slight unevenness of the underside of the natural stone slab is compensated by the first adhesive layer 2; In this case, the thickness of the adhesive layer 2 is slightly larger than the depth of the unevenness to be compensated.
  • a light-weight layer 5 made of extruded and hydrophobized polystyrene is glued by means of a second adhesive layer 4, which serves to increase the overall thickness of the composite panel without substantial increase in weight.
  • the total thickness of the composite panel is so large that it can be used as a kitchen worktop A.
  • Figure 2 shows the bottom view of a kitchen worktop A with a first portion B and a second portion C, which are to be sawed out later for installation of two sinks .
  • the structure of the kitchen worktop A outside the sections B, C is shown in Figure 1, wherein the Thicknesses of the natural stone plate 1 and the lightweight material layer 5 are constant. Since the first portion B is to be sawn later for the installation of two sinks, the first adhesive layer 2, immediately thereafter the second adhesive layer 4 and then the lightweight material layer 5 are arranged in this portion B on the underside of the natural stone slab 1; the reinforcement layer 3 was not arranged in this sub-area 3.
  • the thickness of the second adhesive layer 4 in subregion B is as large as the sum of the thicknesses of reinforcing layer 3 and second adhesive layer 4 in the general region of the worktop A outside the subregions B and C.
  • subarea C which is also to be sawn later for the installation of a sink, both the arrangement of the armor layer 3 and the arrangement of the first adhesive layer 2 was omitted;
  • the height compensation to ensure a constant total thickness of the natural stone composite plate is characterized in that the thickness of the second adhesive layer 4, with which the lightweight material layer 5 is bonded directly to the natural stone slab 1, is as large as the sum of the thicknesses of the first adhesive layer 2, the reinforcement layer 3 and second adhesive layer 4 in the general area of the worktop A outside the sections B and C is.
  • the waiver of the reinforcing layer 3 in the later toracsägenden sections B and C serves both to reduce the manufacturing cost of the countertop A and the reduction of effort when sawing the countertop A. It is also possible, however, not shown in the figures, to arrange the reinforcement layer 3 only in harnessbeabspruchten areas, in particular strip-shaped in edge regions of the worktop.
  • Figures 3 and 4 illustrate an example in which the composite panel is designed in the form of modular components that can be assembled in various forms. This can be used to advantage in the individual design of kitchen countertops. It can thus join together worktops having openings for a sink, a hob and the like, without the difficult to produce in stone slabs recesses must be incorporated. This also greatly reduces the risk of breakage during transport of such plates.
  • Figure 3 shows the top view of two formed in different dimensions as a module component natural stone slabs and a vertical section through such a plate.
  • the plates are rectangular in shape and provided at the front and rear with a side stone plate 1.1. It is also possible to install 1.1 plastic edges instead of natural stone slabs.
  • a protective layer 7 is attached at the bottom of the lightweight material layer 5.
  • the plates are made with a total thickness of 40 mm in the usual kitchen widths of 600 mm.
  • the flagstone has a thickness of 10 mm.
  • At a distance of 25 mm from the rear and front outer edge grooves of 5 mm width are attached to the bottom, in the rod-shaped fasteners can be inserted.
  • the connecting elements ensure the required defined position between adjacent plates or other adjacent module components, for example between plates and the web elements shown in Figure 4.
  • the web elements have the same design up to the width as the plates. They are also provided with lateral natural stone slabs 1.1 and a groove 6.1.
  • a preferred embodiment provides to install two parallel grooves 6.1, in which a U-shaped rail for fixing adjacent module components can be introduced. Further, it is particularly useful for larger plate dimensions to incorporate slots from below, are inserted into the rails with a fast-curing adhesive, so that during the curing of the adhesive layers 2 and 3, a flat concern of the lightweight material layer 5 is secured.
  • a groove 6.2 is incorporated into the natural stone plate on the underside of a thin natural stone slab 1.
  • the natural stone plate 1 is designed as a thin plate with a thickness of 6 to 20 mm, preferably thicknesses of 12 mm are used.
  • a carbon fiber existing strip-shaped stiffening element 8 is fixed by means of a high-strength epoxy resin adhesive layer. Both the strength and the modulus of elasticity of the stiffening element 8 are significantly greater than the strength and the modulus of elasticity of the natural stone slab 1.
  • stiffening elements 8 strips of metal, glass fiber or other suitable materials can be used in addition to the preferred carbon fiber strips.
  • the plates Due to the connection between the pressure-resistant natural stone plate 1 and arranged in the groove 6.2 tensile stiffening element 8 a high bending tensile strength of the worktop is ensured despite low material thickness. This allows both easier processing and calibration of the stone slabs are made possible.
  • the plates are processed from 30 mm thick starting material to the desired thickness of 12 mm or even lower thicknesses. The plates do not require separate substructures to accommodate the processing forces. But it is of course possible to install such substructures. Due to the high modulus of elasticity of the stiffening elements 8 is also on natural stone slabs of small thickness, the moment loads are exposed, only an extremely small deformation, so that a failure of the work surface is also prevented for protruding areas.
  • a lightweight material layer 5 made of plastic is attached to the underside, which in turn is provided on its underside with a plastic layer 9 in the form of a 2 mm thick Resopalplatte.
  • a metal bracket 10 made of stainless steel which fulfills both aesthetic tasks and takes on an additional strength supporting function.
