Description

Mastabspannung. Um Biegungsbeanspruchung hoher Gittermaste zu vermeiden, hat man dieselben auf Kugelgelenke gesetzt. Bei einer Mehrzahl von Abspannstockwerken genügt jedoch dieses Mittel nur unvollkommen, da die Nachgiebigkeit der Abspannseile, bedingt .durch ihren Durchhang, sich nicht so einstellen läßt, daß bei seitlichen Kräften (Winddruck) die Befestigungspunkte der Abspannungen am Mast unter allen Umständen auf einer Geraden bleiben. Man hat deshalb versucht, durch Hilfsabspannungen den Durchhang zu verringern. Da aber die Windbeanspruchung in der Regel mit der Höhe wechselt, die Windgeschwindigkeit in der Höhe oft größer 'ist als am Boden, so hilft dieses Mittel nur unvollkommen.Mast bracing. In order to avoid bending loads on high lattice masts, one has put the same on ball joints. With a plurality of guy floors However, this means is only imperfectly sufficient, since the resilience of the guy ropes, due to their slack, cannot be adjusted in such a way that at the side Forces (wind pressure) the fastening points of the guy lines on the mast under all Circumstances stay on a straight line. Attempts have therefore been made to use auxiliary guy lines to reduce the slack. But since the wind load is usually with the Altitude changes, the wind speed is often greater at altitude than on the ground, so this remedy helps only imperfectly.

Die Erfindung will erreichen, daß eine Biegungsbeanspruchung des Mastes nur zwischen den einzelnen Abspannstockwerken auftritt, daß also die Abspannpunkte unbeweglich werden und es auch nicht nötig ist, den Mast auf ein Gelenk zu stellen.The invention aims to prevent bending stress on the mast occurs only between the individual guy floors, i.e. the guy points become immobile and it is also not necessary to put the mast on a hinge.

Um dazu den Durchhang der Abspannungen zu beseitigen, ohne diese selbst übermäßig zu spannen und, den Mast dadurch allzusehr zusätzlich zu belasten, werden die Abspannungen an besonderen Hilfsseilen aufgehängt, Diese können unmittelbar am Mast oder an Hilfsabspannungen angreifen, die beliebigen Durchhang haben können. Da die Hilfsabspannungen nicht den Mast zu halten, sondern nur das Gewicht der Mastabspannungen zu tragen haben, können sie leicht ausgebildet sein.In order to eliminate the slack in the guy lines without using them themselves excessively tensioning and thereby placing too much additional strain on the mast the guy lines are suspended on special auxiliary ropes, these can be used directly Attack on the mast or on auxiliary guy lines, which can have any sag. Since the auxiliary guy lines do not hold the mast, only the weight of the mast guy lines have to carry, they can be easily trained.

Die oberste Hilfsabspannung kann an der Mastspitze oder an besonderen Auslegern befestigt sein.The top auxiliary guying can be at the top of the mast or at special Be attached to outriggers.

In der Abbildung stellt m den Mast dar, a die Mastabspannungen und n die Hilfsabspannungen, an denen die Mastabspannungen ohne wesentlichen Durchhang aufgehängt sind. Werden die .einzelnen Glieder von a zwischen den Aufhängepunkten steif ausgebildet, so wird ein Durchhang der Mastabspannungen völlig vermieden.In the figure, m represents the mast, a the mast guying and n the auxiliary guy lines on which the mast guy lines have no significant sag are hung. Become the .individual links of a between the suspension points made stiff, so a sagging of the mast bracing is completely avoided.
