Description

Es ist bekannt, Heizkörper für Warmwasser-oder Dampfzentralheizungen aus Stahlblech in der Weise herzustellen, daß man das zunächst ebene Blech unter einer Abkantpresse zu einem flachen Rohrprofil biegt und eine dabei entstehende Längsnaht verschweißt. Diese sog. Plattenheizkörper haben aber den Nachteil, nur bis zu einer Profilhöhe von etwa 250 mm (bei der üblichen Wandstärke von 3 mm) anwendbar zu sein, weil höhere Profile nicht mehr genügend Festigkeit gegen innerenÜberdruck haben und sich aufbeulen. Nun ist aber die unter normalen Verhältnissen benötigte Heizfläche pro Längeneinheit größer als sie diese verhältnismäßig niedrigen Körper haben, so daß man gezwungen ist, mehrere derartige Plattenheizkörper über-oder voreinander anzuordnen (sog. Register). Hierdurch entsteht erhöhte Montagearbeit, und das Bild der Anlage wird durch zusätzliche Schweißnähte, Verbindungsstücke und Haken zur Halterung ungünstig beeinflußt.It is known radiators for hot water or steam central heating made of sheet steel in such a way that the initially flat sheet is under a press brake bends into a flat tube profile and a resulting Welded longitudinal seam. These so-called panel radiators only have the disadvantage Can be used up to a profile height of approx. 250 mm (with the usual wall thickness of 3 mm) to be, because higher profiles no longer have sufficient strength against internal overpressure have and bulge. But this is what is required under normal conditions Heating surface per unit length larger than this relatively low body have, so that one is forced to place several such panel radiators above or in front of one another to be arranged (so-called register). This creates increased assembly work, and the picture the system is provided with additional welds, connectors and hooks Bracket adversely affected.

Bemühungen, nach dem gleichen Verfahren hergestellten höheren Profilen (25o bis Zoo mm) die erforderliche Druckfestigkeit nach bekannten Verfahren, z. B. durch Einpressen von Quersiken oder durch Querverbindungen zwischen den beiden Flachseiten etwa nach Art von Stehbolzen, zu geben, haben wegen der in der Praxis auftretenden teilweise stoßartigen Beanspruchungen nicht zum Erfolg geführt.Efforts to produce higher profiles using the same process (25o to Zoo mm) the required compressive strength according to known methods, e.g. B. by pressing in cross sections or by cross connections between the two Flat sides, for example like stud bolts, have to be given because of the practical use Occurring sometimes sudden loads did not lead to success.

Um höhere als die bisher üblichen Plattenheizkörperprofile mit einer für die Praxis hinreichenden Festigkeit herstellen zu können, wird gemäß der Erfindung ein Blechstreifen durch Umbiegen der beiden längsseitigen Randteile um i8o° über halbkreisförmige oder ähnliche Krümmungen zu einem Profil geformt, dessen umgebogene Ränder in der Mitte einen breiten Spalt offen lassen, in welchem in gewissen Abständen Profilstege mit der Länge der Spaltbreite quer eingeschweißt werden, welche den Abstand der umgebogenen Ränder gegen die gegenüberliegende Plattenfläche fixieren, und der offen gebliebene Spalt schließlich durch einen Blechstreifen passender Breite abgedeckt und zu einem geschlossenen Profil verschweißt.To be higher than the usual plate radiator profiles with a To be able to produce sufficient strength for practice, is according to the invention a sheet metal strip by bending over the two longitudinal edge parts by 180 ° semicircular or similar curvatures formed into a profile, the bent over The edges in the middle leave a wide gap open, in which at certain intervals Profile webs with the length of the gap width are welded transversely, which the Fix the distance between the bent edges and the opposite panel surface, and the gap that remained open through a sheet metal strip of the appropriate width covered and welded to form a closed profile.

In der Abbildung ist oben eine Ausführungsform des fertigen Plattenheizkörpers dargestellt, darunter die Querschnitte a des gebogenen Blechstreifens, b des Profilstegs und c des auf a aufzuschweißenden Blechstreifens.In the picture above is an embodiment of the finished panel radiator shown, including the cross-sections a of the bent sheet metal strip, b of the profile web and c of the sheet metal strip to be welded onto a.

Der Vorteil dieser Konstruktion besteht darin, daß der breite offene Spalt eine gute Zugänglichkeit des Innern zur Anbringung der die Druckfestigkeit erhöhenden Profilstege b gewährleistet, wobei gleichzeitig eine Störung der vorderen glatten Oberfläche durch Siken oder Stehbolzen o. dgl. vermieden wird. Des weiteren ergibt sich eine erhebliche Kostenersparnis bei der Montage gegenüber der Verwendung von Registern aus Plattenheizkörpern geringerer Profilhöhe. Außerdem ist der architektonische Eindruck der größeren ungeteilten Fläche ruhiger, so daß der damit ausgerüstete Raum nicht so sehr den Charakter eines Fabrikraums annimmt, wie bei Registern.The advantage of this construction is that the wide open Gaps a good accessibility of the interior for attachment of the compressive strength increasing profile webs b ensures, at the same time a disruption of the front smooth surface by sinks or studs or the like. Is avoided. Further there is a significant cost saving in assembly compared to use of registers made of panel radiators with a lower profile height. Besides, the architectural one Impression of the larger undivided area calmer, so that the one equipped with it Space does not take on the character of a factory space as much as it does with registers.

PATENTANSPRUCH: Geschweißter Plattenheizkörper, bestehend aus einem ebenen Hohlkörper aus Blech mit Versteifungen, dadurch gekennzeichnet, daß ein Blechstreifen durch Umbiegen der beiden längsseitigen Randteile um i8o° über halbkreisförmige Krümmungen zu einem Profil geformt ist, dessen umgebogene Ränder in der Mitte einen breiten Spalt offen lassen, in welchem in bestimmten gleichen Abständen Profilstege mit der Länge der Spaltbreite eingeschweißt sind, welche den Abstand der umgebogenen Ränder gegen die gegenüberliegende Plattenfläche fixieren, und daß der offen gebliebene Spalt durch einen Blechstreifen passender Breite zu einem geschlossenen Profil verschweißt ist. PATENT CLAIM: Welded plate radiator, consisting of a flat hollow body made of sheet metal with stiffeners, characterized in that a sheet metal strip is formed into a profile by bending the two longitudinal edge parts by 180 ° over semicircular curvatures, the bent edges of which leave a wide gap open in the middle , in which at certain equal intervals profile webs with the length of the gap width are welded, which fix the distance between the bent edges against the opposite plate surface, and that the gap that has remained open is welded to a closed profile by a sheet metal strip of the appropriate width.
