Definitions

  • the invention relates to a plate made of stoneware or ceramic according to the features specified in the preamble of claim 1.
  • Such plates are known from the company publication "FRIDURIT full-size laboratory benchtops ... from Friedrichsfeld AG, D-6800 Mannheim 71, printed notice 1584e.3-VI.92Mz" and are used primarily in chemical laboratories as work surfaces.
  • These plates made of stoneware or ceramic contain edges which protrude above the surface so that in particular caustic or toxic liquids, which can escape from containers, test tubes or the like when experiments are carried out, are retained on the plate.
  • the edges are integral parts of the panels themselves and are thus integrated into the panel during manufacture. Depending on the customer's wishes, the panels with the edges are made to measure, which causes considerable manufacturing and warehousing costs.
  • a profile strip with a water leg for a facade cladding and the like is known.
  • a cladding panel is arranged vertically at a distance in front of a building facade, on the upper edge, in particular below a window ledge or the like, the profile strip is placed.
  • This profile strip has an essentially U-shaped cross section and the water-repellent leg which runs obliquely downwards.
  • the profile strip is fastened by clamping on the upper edge of the cladding panel, with a support or sealing strip made of elastic foam being provided on the inside.
  • a support or sealing strip made of elastic foam
  • the object of the invention is to further develop a plate of the type mentioned in such a way that it can easily be equipped with an edge according to the requirements.
  • the production of the edge should require little work and nevertheless a tight and permanent connection to the plate should be achieved.
  • Special shapes or aids should be avoided during manufacture and a functionally reliable, high load-bearing edge should be created.
  • the proposed panel is characterized by a functionally appropriate construction, whereby a bond between the panel and the edge profile made of plastic, which corresponds to practical requirements, is guaranteed.
  • First panels without edges are prefabricated. These panels are then cut to size according to customer requirements and the plastic edge profiles are placed on the edge, the undercut recess or chamber initially forming a free cavity.
  • the edge profile here advantageously has at least one web or the like for the purpose of defining the edge profile at the edge of the plate at the same time Keep the recess clear. Then the initially liquid or plastic compound is introduced into the recess, which is bounded on the one hand by the edge profile and on the other hand by the edge of the plate.
  • the plastic compound in particular, can be inserted and placed on the edge of the plate together with the edge profile.
  • the edge profile is a molded part which forms a force-fit, firm connection with the panel.
  • the edge profile is permanently attached to the edge of the respective plate by means of the composite reaction mass, which forms a connecting and / or molded body.
  • the edge profile expediently has a basically U-shaped cross section and it has at least one undercut chamber or recess on the inside and thus forms an anchor.
  • the edge profile contains at least one web or the like, which ensures a defined orientation of the same with respect to the plate and a defined specification of the chamber when the edge profile is placed on it.
  • the edge profile has, in particular on the above-mentioned web, inclined walls which delimit the above-mentioned recess in a wedge shape in such a way that a positive connection with the plate is ensured via the compound.
  • the walls arranged in a wedge shape or at an angle in the interior of the edge profile ensure that the edge profile is reliably supported on the hardened composite.
  • the composite which preferably consists of a hardening epoxy resin, enters into a direct connection with the edge of the ceramic or stoneware plate and fills the chamber of the plastic edge profile.
  • the composite material is a molded body which, on the one hand, is non-positively connected to the plate and, on the other hand, ensures the positive connection with the edge profile.
  • the edge profile which consists in particular of polypropylene, has two cheeks, which bear against the mutually parallel surfaces of the plate, preferably under tension. The two cheeks of the edge are in particular slightly tapered before assembly, so that a firm and tight contact with the plate surfaces is ensured after assembly. A chemically resistant, liquid-tight connection is created with little manufacturing effort.
  • the Edges are touch-friendly and impact-protected with a permanent edge profile.
  • Fig. 1 shows schematically a section through a plate 2 in the edge region.
  • the plate 2 consists of stoneware or ceramic and has two mutually parallel surfaces 4, 6, to which the edge 8 is arranged essentially orthogonally.
  • an edge profile 10 made of plastic is arranged, which in principle has a U-shaped cross section with two cheeks 12, 14.
  • the edge profile 10 is made of plastic, in particular polypropylene or PVC, and forms a touch-friendly protection of the edge region of the plate 2.
  • the edge 2 of the plate 2 is protected against impact in its edge regions.
  • the plastic of the edge profile is comparatively hard and possibly has a very small elasticity or resilience, so that the cheeks 12, 14 rest firmly on the surfaces 4, 6 when they are placed on the edge of the panel.
  • the plate 2, of which only a small part can be seen here is cut to size according to the local conditions and the edge profile 10 is subsequently connected to the plate 2.
  • edge profile 10 is perpendicular to the plane of the drawing in the extend each desired length.
  • the edge profile 10 contains a recess 16 inside, the walls 18, 20 of which are arranged inclined with respect to the plate plane 22, the distance between the walls 18, 20 increasing with increasing distance from the edge 8.
  • the walls 18, 20 are each arranged inclined with respect to the central plate plane 22 at a predetermined angle 23, which opens outwards, away from the edge 8.
  • the angle 23 is expediently in the range between 15 to 60 degrees, expediently between 25 to 45 degrees.
  • the recess 16 has an undercut cross section according to the invention. Furthermore, the edge profile 10 contains two recesses 24, 26 which are also inclined with respect to the plate plane 22. The outer walls of these recesses 24, 26 are also inclined at an angle 27 with respect to the plate plane 22, in accordance with the angle 23 explained above Edge profile 10, which is formed in the interior with a grip, thus forms an anchor for connection to the plate.
  • the recesses 16, 24, 26 are open to the edge 8 and are limited by this.
  • a reaction composite compound 28 is provided in the recesses 16, 24, 26 of the edge profile.
  • This initially liquid or plastic composite reaction mass 28 consists in particular of a hardening epoxy resin, is introduced after the edge profile 10 has been placed in the undercut recess 16 or chamber according to the invention, which is further delimited by the plate edge 8, in particular by casting.
  • the initially liquid or plastic reaction mass can be introduced into the chamber or recess 16 before the edge profile 10 is placed on it and subsequently placed together with the edge profile 10 on the plate edge. After solidification or hardening, the compound 28 ensures an inseparable and / or non-positive connection with the edge 8 of the plate 2.
  • the reaction compound 28 adheres firmly to the plate 2 made of stoneware or ceramic, but not to the plastic of the edge profile 2, with which such a connection of the composite mass 28 is not possible.
  • the undercut recesses of the edge profile 10 thus form a shape for the composite reaction mass 28 and the molded body produced therefrom after curing.
  • This molded body from the composite reaction mass is non-positively connected to the plate 2, while there is a positive connection to anchor the edge profile 10. Due to the rear-engaging design of the edge profile 10, a positive connection is guaranteed according to the invention. A chemically stable and liquid-tight connection is thus produced between the plastic edge profile 10 and the plate 2.
  • the edge profile 10 has in each case a web 29, 30 between the adjacent recesses 24, 28, 26, which are also inclined in relation to the longitudinal plane 22 of the plate in accordance with the angles 23 and 27. These webs 29, 30 ensure that the recesses 16, 24, 26 remain when the edge profile 10 is placed on the edge of the plate and that a defined edge alignment is ensured. Since the edge profile consists of a comparatively hard plastic with high rigidity, there is no deformation of the webs 29, 30 to be observed either when the edge profile is installed on the edge of the plate or later after the recesses have been filled with the reaction composite compound 28. The walls 18, 20 formed by the inner side surfaces of the webs 29, 30 are consequently, like the webs 29, 30 themselves, dimensionally stable, so that detachment of the edge profile 10 away from the plate edge 8 is not possible in practice.
  • the design of the outer surface 31 of the edge profile 10 is specified in accordance with the requirements, rounded corners 32 having proven to be useful.
  • the cheeks 12, 14 of the edge profile 10 overlap near the edge 8 in the manner shown, a small part of the surfaces 4, 6.
  • the edge profile 10 is designed such that the cheeks 12, 14 with the panel 2 before assembly and connection their inner surfaces are arranged slightly conically inclined with respect to the longitudinal plane 22 of the plate, as indicated by the dash-dotted lines 34, 36. After assembly, the cheeks 12, 14 lie reliably and tightly against the surfaces 4, 6 under pretension.
  • FIG. 2 shows a further embodiment with two recesses 38, 40, which are inclined to the longitudinal plane 22 and engage behind the recesses.
  • the recesses 38, 40 in turn have inclined walls 42, 44, which are in relation to the plate longitudinal plane 22 are arranged at an outwardly opening angle 46.
  • small webs 48, 49 are provided on the edge 8 in the interior of the clamping profile 10 for the purpose of defining the system.
  • the solidified and / or hardened reaction composite 28 forms a firm and inseparable connecting body with the ceramic or stoneware plate, wherein the recesses 38, 40 filled with the composite 28 provide a positive connection.
