@erartige Verfahren weiser/insbesondere bei der Massenherstellung erschiedene Nachteile auf 0 So ist z.B. ein wesentlicher Aufwand an Arbeitskräften erforderlich7 um die einzelnen Bleche in getrennten Arbeitsgängen zu profilieren, zusammenzufügen und das Wandelement später aus der rorm zu nehmen0 Weiterhin müssen die Seiten der Stahlbleche durch Kunststoff oder Metallprofile auf Abstand gehalten werden9 so daß auch ein zusätzlicher Materialaufwand erforderlich ist.@ such processes wiser / especially in mass production Various disadvantages to 0 For example, there is a substantial effort at Labor required7 to separate the individual sheets to profile, join together and later remove the wall element from the rorm0 Furthermore, the sides of the steel sheets must be made of plastic or metal profiles be kept at a distance9 so that additional material costs are also required is.
Das Profilieren jedes einzelnen Stahlbleches bringt außerdem Verlustzeiten für den Transport und bei diesem insbesondere bei beschichteten Stahlblechen die Gefahr, daß die Schutzschicht beschädigt wird, beim fertigen Wandelement also später nachgearbeitet werden mußO Schließlich sind bei wechselnden Fertiglängen sämtliche Vorrichtungen auf die jeweilige Länge bzw. auf die entsprechenden Zeiten oder Geschwindigkeiten einzustellen oder umzubauen.Profiling every single sheet of steel also results in lost time for the transport and in this particular with coated steel sheets the There is a risk that the protective layer will be damaged, so later with the finished wall element must be reworked. Finally, with changing finished lengths, all Devices to the respective length or to the corresponding times or speeds adjust or convert.
Der Erfindung liegt die Aufgabe zugrunde9 die Nachteile der vorbekannten Verfahren und Einrichtungen zu vermeiden und bessere Voraussetzungen ur eine Massenherstellung zu schaffen Ausgehend von dem oben näher bezeichneten Verfahren zur Herstellung von Wandelementen wird dazu gemäß der Erfindung vorgeschlagen, daß die beiden Stahibleche kontinuierlich von je einem Coil ablaufen9 gleichzeitig an beiden Seiten profiliert und nach Durchlaufen einer sie zu einem Wandelement zusammenfügenden Fördervorrichtung auf Lunge geschnitten werden0 Durch das vorgeschlagene Verfahren kann nunmehr die Herstellung vom Bandstahlcoil bis zum fertigen Wandelement verschiedener Länge selbstj,tig und kontinuierlich erfolgen, wobei Verlustzeiten für Transport bzw. für den Umbau bei abweichenden Längen sowie auch die gefahr von Beschädigungen der Schutzschicht weitgehend vermieden werden.The invention is based on the disadvantages of the known ones Processes and facilities to avoid and better conditions for mass production to be created on the basis of the manufacturing method described in more detail above of wall elements is proposed according to the invention that the two steel sheets run continuously from one coil each9 profiled on both sides at the same time and after passing through a conveying device which joins them together to form a wall element be cut on lungs0 By the proposed method The production from steel strip coil to the finished wall element can now be done in different ways Length even and continuously, with loss of time for transport or for the conversion with deviating lengths as well as the risk of damage the protective layer can be largely avoided.
Da, gemäß einem weiteren Merkmal der Erfindung9 die Stahlbleche in der Fördervorrichtung durch die von dieser ausgeübten Zugkraft auf Abstand gehalten werden und auf die Längsränder der Stahlbleche eine kontinuierlich zulaufende Papierfolie aufgebracht wird kann auch das bisher zur Abstandshaltung und Seitenbegrenzung erforderliche seitliche Kunststoff- oder Metallprofil entfallen.Since, according to a further feature of the invention9, the steel sheets in the conveyor is kept at a distance by the tensile force exerted by it and a continuously tapering paper foil on the longitudinal edges of the steel sheets can also be applied that previously required for spacing and side delimitation Lateral plastic or metal profiles are not required.
Von besonderem Vorteil hat sich weiterhin erwiesen, da# die Erwärmung der Stahlbleche durch Auslenkung der Heizstrahler bei gleichbleibender Heizleistung geregelt vard9 da eine Leistungsregelung für die erfindungsgemäß e kontinuierliche Herstellung zu träge ist.It has also proven to be particularly advantageous that the heating of the steel sheets by deflecting the radiant heater with constant heating power regulated vard9 there is a power regulation for the continuous according to the invention Manufacturing is too sluggish.
