Abstract
Description
Es handelt sich um eine Haltekonstruktion für Strommasten.It is a holding structure for electricity pylons.
Zahlreiche Strommasten sind in den letzten Jahren in Deutschland, insbesondere im Münsterland, durch sehr hohe Windbelastungen umgeknickt. Ursachen sind u. a. Werkstoffermüdungen des Thomasstahls. 1) 2)numerous Electricity pylons are in Germany in recent years, in particular in the Münsterland, overturned by very high wind loads. Causes are u. a. Material fatigue Thomasstahls. 1) 2)
Diese Masten sind zum Teil ausgewechselt worden. Andere Strommasten könnten in Zukunft ebenfalls umknicken.These Masts have been partially replaced. Other electricity pylons could be in Also change the future.
Um dieses zu verhindern dient die Konstruktion. Hierbei sollen vier lange Winkelprofile um den alten Strommast geschraubt werden. Dabei ist auf die ursprüngliche Erhaltung der Grundkonstruktion Wert gelegt worden. Es finden keine Werkstoffveränderungen statt. Weder Querschnittsveränderungen durch evtl. Bohrungen noch Werkstoffveränderungen durch Schweißen beanspruchen die alte Grundkonstruktion.Around To prevent this, the construction is used. Here are four long angle profiles are screwed around the old power pole. there is on the original one Conservation of the basic construction value has been placed. There are no Material changes instead of. Neither cross-sectional changes by possibly drill holes nor material changes by welding claim the old basic construction.
Die vier Außenwinkel sollen die Grundkonstruktion bei starker Windbelastung, insbesondere gegen Knickung, stützen.The four outside angles should the basic construction in strong wind load, especially against Buckling, support.
Sie werden als ca. 3 m lange Winkel erst vor Ort, durch Schweißen auf Ihre Gesamtlänge verbunden. Dadurch entstehen vier verschieden Stützwinkel. Jeder Stützwinkel beträgt dann ca. drei Viertel der Gesamtlänge des Strommastes.she be as about 3 m long angle on site, by welding on Your total length connected. This creates four different support angles. Every support angle is then about three quarters of the total length of the power pole.
Danach
sind die Bandeisen (
Die Winkel welche ca. 0.6 m lang sind, sollen die Spannkräfte durch eine gleichmäßigere Flächenpressung besser verteilen.The Angle which are about 0.6 m long, the clamping forces to a more uniform surface pressure distribute better.
In dieser Spannebene werden die Bandeisen dann miteinander verschraubt.In this span level, the straps are then bolted together.
Hierbei ist darauf zu achten, dass die Elastomerlager mit einer gewissen Vorspannung belastet werden.in this connection make sure that the elastomeric bearings with a certain Preload be charged.
Ca.
3 m vor dem oberen Ende des Strommastes wird ein Anschlag (
Würden nur die Spannungsbänder ohne Elastomerlager verwendet werden, so würde sich ein sehr hohes Biegemoment an der Einspannstelle (unten am Sockel) aufbauen.Would only the voltage bands Without elastomeric bearings used, so would a very high bending moment at the clamping point (bottom of the base) build.
Die Elastomerlager mindern diese Spannungsspitzen jedoch erheblich.The Elastomeric bearings significantly reduce these voltage spikes.
Die vier Stützwinkel, in Verbindung mit den Bandeisen bilden, wie beschrieben, eine elastische Stützhaltekonstruktion.The four support angles, in conjunction with the straps, as described, form an elastic support structure.
