Abstract

A sheet metal covering strip (10; 110; 210; 310) is disclosed, in particular for buildings or the like. In order to create a sheet metal covering strip which is easy to produce, which may be easily bordered without tools in one or several predetermined, substantially linear areas and which is otherwise stiff and may be laid with an overlapping section on a similar sheet metal covering strip, so as to prolong it, the sheet metal covering strip (10; 110; 210; 310) consists in at least one preferably longitudinal narrow area (12; 112; 212; 312) of a material of less resistance and higher breaking elongation than the material in the adjacent areas (26, 28; 126, 128; 226, 228; 326, 328) of the sheet metal covering strip (10; 110; 210; 310). The narrow area(s) of the disclosed sheet metal covering strip may be made of another metal, another metal alloy or of the same metal but with a different structure than the remaining areas, or of a non-metallic material such as plastics. The material of the narrow areas may be joined in a water-tight manner to the material of the adjacent areas, for example by overlapping. Areas having different structures may be obtained by cold forming or by softening in a strip made of a uniform metallic raw material. The flexibility of the sheet metal varies from area to area. The narrow areas have less resistance and higher breaking elongation than the adjacent areas and constitute predetermined bending lines.

Die Erfindung betrifft einen Abdeckblechstreifen insbesondere für ein Bauwerk oder dergleichen. Derartige Abdeckblechstreifen werden beispielsweise zur Abdeckung der Kehlrinne in der Kehle zwischen zwei zusammentreffenden geneigten Flächen eines Daches oder zur Abdeckung der Kanten an einem über die Dachfläche herausragenden Bauteil verwendet. Der zur Abdeckung verwendete Blechstreifen muß den bauseitigen Gegebenheiten entsprechend abgekantet werden. Um eine saubere Biegekante herzustellen ist auf der Baustelle oder in der Werkstatt eine Abkantvorrichtung erforderlich.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.
Der Erfindung liegt die Aufgabe zugrunde, einen Abdeckblechstreifen zu schaffen, der einfach herstellbar ist, der in einem oder mehreren vorgegebenen im wesentlichen linienförmigen schmalen Bereichen ohne Werkzeug leicht abkantbar und im übrigen steif ist und zur Verlängerung mit einem gleichen Abdeckblechstreifen abschnittweise überdeckend verlegt werden kann.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.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Abdeckblechstreifen in zumindest einem vorzugsweise inAccording to the invention, this object is achieved in that the cover strip is preferably in at least one

Der erfindungsgemäße Abdeckblechstreifen ist besonders gut zur Abdeckung einer Kehlrinne geeignet, wenn zumindest drei in Längsrichtung verlaufende schmale Bereiche mit einem Material mit geringerer Festigkeit und höherer Bruchdehnung als in den übrigen Bereichen vorgesehen sind, und zwar einer in derThe 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
Längsmitte und je einer benachbart zum jeweiligen Seitenrand. Sofern im Randbereich eine weitere Abkantung erforderlich ist, können zusätzlich weitere in Längsrichtung verlaufende schmale Bereiche mit einem Gefüge mit geringerer Festigkeit und höherer Bruchdehnung als in den übrigen Bereichen vorgesehen sein.Longitudinal center and one adjacent to the respective side edge. If a further beveling is required in the edge area, further narrow areas running in the longitudinal direction with a structure with lower strength and higher elongation at break than in the other areas.
Der oder die schmalen Bereiche eines erfindungsgemäßen Abdeckblechstreifens können aus einem anderen Metall, einer anderen Metallegierung oder aus demselben Metall jedoch mit einem anderen Gefüge als in den übrigen Bereichen oder aber aus einem nichtmetallischen Werkstoff wie Kunststoff bestehen. Das Material der schmalen Bereiche kann beispielsweise durch Verfalzen mit dem Material der angrenzenden Bereiche wasserdicht verbunden sein.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.
Eine besonders einfache Herstellung ist möglich, wenn in einem Band aus einheitlichem metallischem Rohmaterial durch KaltVerformung bzw. Weichglühen erzeugte Bereiche mit unterschiedlichen Gefügen vorhanden sind, in denen das Blech verschieden leicht abbiegbar ist, wobei die schmalen Bereiche ein Gefüge mit geringerer Festigkeit und höherer Bruchdehnung als die angrenzenden Bereiche aufweisen.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.
Dies kann dadurch erreicht werden, daß das Metall des Abdeckblechs außer in einem oder mehreren schmalen Bereichen durch Kaltverformung ein Gefüge mit hoher Festigkeit erhält. Die schmalen Bereiche stellen vorgegebene Biegelinien dar. Der Abdeckblechstreifen kann in ebener Form geliefert werden, sodaß bei der Lagerung und beim Transport wenig Platz benötigt wird. Eine Abkantung des erfindungsgemäßenThis can be achieved in that 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. A bevel of the invention
Abdeckblechstreifens ist auf der Baustelle sehr einfach und ohne Abkantwerkzeug durchführbar, indem der Abdeckblechstreifen entlang der vorgegebenen Biegelinie auf den Rand eines Tisches oder Brettes gelegt wird und der überstehende versteifte Bereich mit der Hand abgebogen wird.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.
Als einheitliches Rohmaterial zur Herstellung des erfindungsgemäßen Abdeckblechstreifens ist jedes Metall geeignet, bei dem durch Kaltverformen die Streckgrenze auf wenigstens etwa den doppelten Wert erhöht und die Bruchdehnung auf etwa die Hälfte oder weniger reduziert werden kann. Als Metall, dessen Gefüge durch Kaltverformung leicht veränderbar ist, eignet sich Aluminium besonders gut. In dem Buch "Werkstoffkunde und Werkstoffprüfung" von Wilhelm Domke, 2.Aufläge, Girardet Verlag Essen, sind auf Seite 190 folgende Werte angegeben: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. In the book "Materials Science and Materials Testing" by Wilhelm Domke, 2nd edition, Girardet Verlag Essen, the following values are given on page 190:

Eine besonders gute Witterungsbeständigkeit wird erreicht, wenn zumindest auf der Oberseite des Abdeckblechstreifens eine korrosionsschützende Schicht vorgesehen ist. Die Schicht kann aus Farbe oder Kunststoff bestehen, auch Brünieren ist möglich. Wenn der Abdeckblechstreifen aus Aluminium besteht, kann die Oberfläche eloxiert sein.Particularly good weather resistance is achieved if 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.
Ein beschichteter Abdeckblechstreifen kann im Dachbereich universell eingesetzt werden, wenn Oberseite und Unterseite verschiedenfarbig beschichtet sind, so daß auf der Baustelle die Abkantung so ausgeführt werden kann, daß die zur Farbe der Dacheindeckung passend gefärbte Seite oben zu liegen kommt.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.
Zur Herstellung des Abdecklechstreifens kann einerseits als Rohmaterial kaltverformtes Metallblech eingesetzt werden, welches einen oder mehrere schmale Bereiche mit einem durch gezielte Erwärmung erzeugten Gefüge mit geringerer Festigkeit und höherer Bruchdehnung aufweist. Bei kaltverformtem Aluminium kann eine Gefügeveränderung durch eine Erwärmung auf 300°C bis 460°C erreicht werden. Es versteht sich, daß der ein Gefüge mit verminderter Festigkeit enthaltende Bereich möglichst schmal ausgebildet sein muß. Dies ist beispielsweise dadurch erreichbar, daß die Erwärmung durch eine Flamme, durch Strahlung, durch elektrische Widerstandsheizung, induktive Heizung oder durch Plasma erfolgt. Die Erwärmung durch Strahlung kann beispielsweise mit Laserstrahlen oder Elektronenstrahlen erfolgen.To produce the cover sheet strip, 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. With cold-formed aluminum, a change in structure due to heating can occur 300 ° C to 460 ° C can be reached. It is understood that 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.
Andererseits kann auch das Rohmaterial desOn the other hand, the raw material of the
Abdeckblechstreifens weiches Metallblech sein, das in an einen oder mehrere schmale Bereiche angrenzenden breiten Bereichen ein durch Kaltverformung erzeugtes Gefüge mit erhöhter Festigkeit aufweist. In diesem Fall erfolgt die Kaltverformung nicht über die gesamte Breite des Rohmaterialbandes sondern nur partiell.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.
Bei der Kaltverformung, beispielsweise durch Walzen, Pressen oder Prägen, erfolgt meist auch eine wenn auch nur geringe Vergrößerung der kaltverformten Fläche. Dadurch ergeben sich gegenüber den nicht nachbehandelten schmalen Bereichen Spannungen, die zu einer unebenen verbeult erscheinenden Oberfläche führen.In cold forming, for example by rolling, pressing or embossing, 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.
Die Vergrößerung der Fläche kann durch entsprechendeThe area can be enlarged by appropriate
Profilierung der Oberfläche ausgeglichen werden, wenn der Abdeckblechstreifen im wesentlichen in Querrichtung verlaufende Sicken aufweist und in dem oder den schmalen Bereichen im wesentlichen flach ausgebildet ist. Dies kann dadurch erreicht werden, daß nur in den zu versteifendenProfiling 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
Bereichen des ursprünglich flachen Abdeckblechstreifens mit Prägestempeln oder mit Profilwalzen Sicken eingeprägt werden. Als Rohmaterial für den Abdeckblechstreifen eignet sich weiches Aluminium besonders gut, insbesondere mit einer Dicke von weniger als 1 mm. Beim Einprägen der Sicken wird weiches Aluminium infolge von Gefügeveränderung gehärtet, so daß die Versteifung sowohl durch diese als auch zusätzlich noch durch die Formgebung erzielt wird. Es versteht sich, daß eine zusätzliche Versteifung durch Sicken stets möglich ist, also auch bei einem Abdeckblechstreifen, dessen schmale Bereiche aus nichtmetallischem Werkstoff bestehen.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. When 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.
Bei einem für die Abdeckung einer Kehlrinne verwendeten Abdeckblechstreifen wird Regenwasser besonders gut zur Längsmitte geleitet, wenn die Sicken in der Draufsicht gesehen pfeilförmig zur Längsmitte angeordnet sind. Der Spitzenwinkel der fischgrätenartig angeordneten Sicken sollte etwa 120° bis 140° betragen.In the case of a cover sheet strip used for covering a gutter, rainwater is conducted particularly well to the longitudinal center if the beads are arranged in the shape of an arrow to the longitudinal center when viewed in plan view. The point angle of the herringbone-like beads should be about 120 ° to 140 °.
Die Sicken können ein im Längsschnitt sägezahnförmiges Profil aufweisen. Bei Verlegung des Abdeckblechstreifens auf einem Dach werden die kurzen Abschnitte des Profils zur Traufe hin abfallend angeordnet, so daß die Oberfläche eine Art Treppe bildet, auf der Regenwasser gut abfließen kann.The beads can have a sawtooth-shaped profile in longitudinal section. When the cover strip is laid on a roof, 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.
Die Steifigkeit kann erhöht werden, wenn die Sicken ein im Längsschnitt trapezförmiges Profil aufweisen. Die Sicken können abwechselnd zur Ober- und zur Unterseite geprägt sein, so daß sich ein im Längsschnitt etwa wellenförmiges Profil ergibt.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.
Eine besonders hohe Steifigkeit wird erreicht, wenn die Sicken aneinandergrenzend angeordnet sind und der Trapezwinkel weniger als 45°, die Tiefe des Profils weniger als 5 mm, vorzugsweise etwa 3 mm, und der Sickenabstand weniger als 50 mm, vorzugsweise etwa 16 mm beträgt.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.
Eine beidseitige Anwendung des Abdeckblechstreifens ist möglich, wenn die schmalen Bereiche in der Höhenlage mittig zur Profilierung angeordnet sind.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.
Wenn zusätzlich zu einem mittleren schmalen Bereich nahe denIf in addition to a medium narrow area near the
Seitenrändern ein oder zwei weitere schmale Bereiche mit einem Gefüge mit geringerer Festigkeit und höherer Bruchdehnung als in den übrigen Bereichen des Abdeckblechstreifens vorgesehen sind, so ist eine gemeinsame Abkantung zweier aufeinander liegender Abdeckblechstreifen im Bereich der Überlappung besonders leicht möglich, wenn die seitlichen schmalen Bereiche eine Breite von wenigstens 10 mm aufweisen.Side edges of one or two further narrow areas with a structure with lower strength and greater elongation at break than are provided in the remaining areas of the cover plate strip, this is a common folding of two on top of each other lying cover sheet strips in the area of the overlap particularly easily possible if the lateral narrow areas have a width of at least 10 mm.
