Definitions

• the invention relates to a building closure with a relocatable gate or door leaf, which is designed in one piece or in several parts from several panel bodies hingedly connected to one another, the cross-sectional structure of which essentially consists of a metal cover element on the outside of the leaf and an inside of the leaf, with the cavity present between the cover elements having filled with an insulating core.
• a panel element which consists of a pair of sheets connected in a sandwich-like manner with an insulating layer in between.
• a door leaf for a sectional door made of articulated panels which are each formed from a sheet metal shell on the outside of the sheet and a sheet metal cover on the inside of the sheet that closes the sheet metal shell and are foam-filled with insulating material DE 10 255 729 B3 .
• insulating materials are incorporated between two outer cover plates in gates, especially sectional gates or doors, so that a sandwich-like element with the highest possible mechanical strength is created.
• Such elements are relatively cheap to produce, while at the same time high sound and heat insulation is achieved. However, such elements do not have a very high burglary security.
• the feasibility of burglary protection should only result in a slight increase in the weight of the building lock, but at the same time achieve high stability in the building locks.
• the executability of burglary security should be easy to process and also retrospectively executable for existing building locks.
• the fire protection behavior of the building locks should also not be impaired by the increased burglary protection.
• Doors or gates in particular sectional doors with their leaves, are understood to be building closures. So that these leaves of building closures can be made more burglar-proof, a plate made of thermoplastic is additionally attached flat to the cover element on the inside of the leaf.
• the thermoplastic material is significantly lighter than the metallic cover elements of the gates and doors.
• the use of thermoplastic panels therefore does not lead to a significant increase in the weight of such a gate or door leaf.
• Such a panel is weather-resistant and impact-resistant and has a high level of rigidity.
• Polycarbonates or polymethyl methacrylate, for example, can be used as the material for such a plate.
• Polycarbonates usually have a crystallite content of at least 5% and are therefore considered amorphous. This is what makes them stand out high strength, impact strength, rigidity and hardness. They are also very resistant to water and many mineral acids and aqueous solutions. They are also flame retardant because a flame on a polycarbonate will extinguish immediately when the primary flame impact is removed. As a result, polycarbonate meets the requirements of fire class B1 or B2.
• the plates can be used in different layer thicknesses and are between one and several millimeters.
• Polycarbonates can be processed very easily in layer thicknesses and also show no post-shrinkage.
• Such panels made of polycarbonate can be securely connected to the metallic cover elements, even in the painted state, subsequently or already during the production process by means of adhesive tapes or adhesive materials.
• adhesive tapes or adhesive materials In addition to an integral connection, it is also possible to attach such panels to the inside cover elements in an exchangeable manner by means of screw connections.
• the connection between the plate and the metallic cover layer can also be carried out by a blind rivet.
• a hybrid element is created by such connection designs in the door and gate leaves with the additional thermoplastic panels.
• glass fibers In order to achieve even higher strength, rigidity and creep resistance, it is possible for glass fibers to be added to the polycarbonate.
• the proportion of glass fibers can be around 30%.
• the combination of the material polycarbonate in connection with glass fibers makes such a sheet-like material particularly suitable for being exposed to high loads at high temperatures over long periods of time.
• polymethyl methacrylate Another material that can be bonded to the sheet-inside cover member is polymethyl methacrylate.
• Polymethyl methacrylate is also a thermoplastic that is inexpensive to produce in sheet form. This material also has properties of resistance to breakage and is very impact-resistant. This material is also weatherproof and UV-resistant and, with a density of 1.19 g/cm 3 , very light. The densities of polymethyl methacrylate and polycarbonate are roughly comparable. Also, polymethyl methacrylate is flame retardant when the primary flame effect is removed. As a result, polymethyl methacrylate meets the requirements of fire class B1 or B2.
• Polymethyl methacrylate can be bonded to the metallic or painted surfaces of the inner blade cover elements using a wide range of high-performance adhesives for an efficient hybrid connection.
• solvent-based adhesives can be used that harden quickly and thus offer rapid initial strength with the additional plate applied to the inside of the cover surface of the cover element.
• 2-component adhesives can also be used. In principle, even construction silicone can be used well for gluing the panels in the edge area.
• adhesive tapes can also be used with this material.
• connection options which are not exhaustively listed, it is of course possible, just as with the polycarbonates, to attach the panels to the cover element by means of screw connections or other mechanical means.
• Both the material connections, as well as the screw connections or rivet connections in connection with the attached plates and the cover elements on the inside of the blade, can preferably be carried out in the edge areas. This is due to the Outstanding material properties provide secure burglary protection against intrusion from the outside into the interior of the building.
• a burglar-proof variant can be provided in a simple and cost-effective design both for single-leaf doors and for multi-part door elements, such as sectional doors with their panel bodies.
• This is achieved in particular by the fact that there is basically a flat hybrid element consisting of two spaced, metallic cover elements and the cavity filled in between with an insulating core and the inner surface of an element is additionally combined with a plate made of polycarbonate or polymethyl methacrylate.
