Definitions

• the invention relates to a cover strip, in particular for a building or the like.
• Cover plate strips of this type are used, for example, to cover the gutter in the throat between two meeting inclined surfaces of a roof or to cover the edges on a component projecting beyond the roof surface.
• the sheet metal strip used for covering must be folded according to the on-site conditions. In order to produce a clean bending edge, a folding device is required on the construction site or in the workshop.
• the invention has for its object to provide a cover strip that is easy to manufacture, which can be easily bent without tools in one or more predetermined substantially linear narrow areas and is otherwise stiff and can be laid in sections overlapping for extension with the same cover strip.
• the cover strip is preferably in at least one
• the cover sheet strip according to the invention is particularly well suited for covering a gutter if at least three narrow areas running in the longitudinal direction are provided with a material with lower strength and higher elongation at break than in the other areas, namely one in the
• the narrow area or areas of a cover plate strip according to the invention can consist of a different metal, a different metal alloy or of the same metal but with a different structure than in the other areas or of a non-metallic material such as plastic.
• the material of the narrow areas can, for example, be watertightly bonded to the material of the adjacent areas.
• a particularly simple manufacture is possible if areas with different structures, in which the sheet metal can be bent differently, are present in a strip made of uniform metallic raw material by cold working or soft annealing, the narrow areas being a structure with lower strength and higher elongation at break than have the adjacent areas.
• the metal of the cover plate apart from in one or more narrow areas, is given a structure with high strength by cold working.
• the narrow areas represent predetermined bending lines.
• the cover plate strip can be supplied in a flat form, so that little space is required for storage and transport.
• Cover plate strip is very easy to carry out on the construction site and without any folding tools, by placing the cover plate strip along the specified bending line on the edge of a table or board and bending the protruding stiffened area by hand.
• any metal is suitable as a uniform raw material for the production of the cover sheet strip according to the invention, in which cold deformation increases the yield strength to at least about twice the value and the elongation at break can be reduced to about half or less.
• Aluminum is particularly suitable as a metal, the structure of which can be easily changed by cold working.
• a corrosion-protective layer is provided at least on the upper side of the cover plate strip.
• the layer can consist of paint or plastic, blackening is also possible. If the cover strip is made of aluminum, the surface can be anodized.
• a coated cover strip can be used universally in the roof area if the top and bottom are coated in different colors, so that on the construction site the bend can be made so that the colored side of the roof covering comes to lie on top.
• cold-formed metal sheet can be used as the raw material, which has one or more narrow areas with a structure produced by targeted heating with lower strength and higher elongation at break.
• a change in structure due to heating can occur 300 ° C to 460 ° C can be reached.
• the area containing a structure with reduced strength must be as narrow as possible. This can be achieved, for example, by heating by a flame, by radiation, by electrical resistance heating, inductive heating or by plasma. Heating by radiation can take place, for example, with laser beams or electron beams.
• Cover plate strip soft metal sheet which has a structure produced by cold deformation with increased strength in one or more narrow areas adjacent to one another. In this case, the cold forming does not take place over the entire width of the raw material strip, but only partially.
• the cold-formed surface is usually also enlarged, albeit only slightly. This results in tensions in relation to the untreated narrow areas, which lead to an uneven, dented surface.
• the area can be enlarged by appropriate
• Profiling of the surface can be compensated for if the cover plate strip has beads which run essentially in the transverse direction and is essentially flat in the narrow area or areas. This can be achieved by using only those to be stiffened
• Areas of the originally flat cover plate strip can be embossed with embossing stamps or with profile rollers.
• Soft aluminum is particularly suitable as a raw material for the cover strip, in particular with a thickness of less than 1 mm.
• embossing the beads soft aluminum is hardened as a result of structural changes, so that the stiffening is achieved both by this and also by the shape. It goes without saying that additional stiffening by beads is always possible, that is to say also in the case of a cover sheet strip, the narrow areas of which are made of non-metallic material.
• the beads can have a sawtooth-shaped profile in longitudinal section.
• the short sections of the profile are arranged so that they slope down towards the eaves, so that the surface forms a kind of staircase on which rainwater can drain off easily.
• the rigidity can be increased if the beads have a profile which is trapezoidal in longitudinal section.
• the beads can be embossed alternately to the top and bottom, so that there is an approximately wavy profile in longitudinal section.
• a particularly high rigidity is achieved if the beads are arranged adjacent to one another and the trapezoidal angle is less than 45 °, the depth of the profile is less than 5 mm, preferably about 3 mm, and the bead spacing is less than 50 mm, preferably about 16 mm.
• the cover plate strip can be used on both sides if the narrow areas are arranged in the middle of the profile in relation to the height.
