Abstract

Das Einrichten von Mastfüßen großer Spreizung ist wegen der großen Abmessungen bei der Montage von Gittermasten für Hochspannungs-Freileitungen relativ schwierig und umständlich. Der Erfindung liegt deshalb die Aufgabe zugrunde, das Einrichten von Mastfüßen großer Spreizung zu vereinfachen. Dies geschieht erfindungsgemäß so, daß an einem im Mastmittelpunkt angeordneten Befestigungsrahmen vier Tragarme kreuzförmig angeordnet sind, daß die Tragarme seitlich verschwenkbar an ihrem anderen Ende auf einem Tragarm arretierbar sind, daß an dem freien Ende der Tragarme ein in seinem Neigungswinkel einstellbarer Halter angelenkt ist, daß der Halter eine lösbare Befestigung für einen Eckstiel aufweist, daß die Tragarme in ihrer Länge verstellbar sind, und daß Befestigungsrahmen und Tragrahmen höhenverstellbar sind.Setting up mast feet with a large spread is relatively difficult and cumbersome because of the large dimensions when assembling lattice masts for high-voltage overhead lines. The invention is therefore based on the object of simplifying the setting up of mast feet with a large spread. This is done according to the invention in such a way that four support arms are arranged in a cross shape on a mounting frame arranged in the mast center, that the support arms can be locked laterally pivotable at their other end on a support arm, that a holder adjustable in its angle of inclination is hinged to the free end of the support arms, that the holder has a detachable attachment for a corner post, that the support arms are adjustable in length, and that the mounting frame and support frame are adjustable in height.

Description

zur Höheneinstellung an den Ecken mit Gewindespindel 11 versehen.Provided with threaded spindle 11 for height adjustment at the corners.

Das Einrichten der vier Eckstiele 9 des nicht näher dargestellten Mastfußes geschieht wie folgt: Zunächst wird der Befestigungsrahmen 1 über eine mittig angebrachte Markierung 12 auf den Masünittelpunkt zentriert, in dem der Gittermast errichtet werden solL Anschließend erfolgt die horizontale Ausrichtung des Befestigungsrahmens 1 urd seine Fixierung über an den Gewindespindeln 11 befestigte Fußbleche 13, durch deren öffnungen Erdnägel 16 in den Boden getrieben werden. Es werden nun die vier Tragarme 2 an den Ecken des quadratischen Befestigungsrahmens 1 mit einer Gewindeschraube 17 zunächst locker befestigt, so daß sie seitlich verschwenkbar sind. Vor den vier Baugruben 14 werden die Tragrahmen 3 aufgestellt, wobei eine Seite des dreieckförmigen Tragrahmens gegen die Baugrube weist Auf die Tragrahmen 3 kommen die Tragarme 2 mit ihren Gabeln 4 zu liegen. Nachdem die Tragarme 2 auf Länge eingestellt und zueinander in genaue Position gebracht worden sind, sowie zusammen mit den Tragrahmen 3 die horizontale Ausrichtung erfolgt ist, werden die Tragarme 2 durch Anziehen der Gewindeschrauben 17 sowie mit Hilfe von auf den Tragrahmen 3 angeordneten Spannbügeln 15 fixiert. Zuletzt werden in die Halter 6 die Eckstiele 9 eingespannt und der entsprechende Neigungswinkel eingestellt, so daß die Eckstiele genau positioniert, mit ihren freien Enden in die Baugrube ragen, die anschließend mit Beton verfüllt wird. Nachdem Abbinden des Betons wird die Vorrichtung entfernt und es kann mit der Montage des Mastfußes auf den vier Eckstielen begonnen werden.The four corner posts 9 of the mast base, not shown in detail, are set up as follows: First of all, the fastening frame 1 is centered on the center point in which the lattice mast will be erected by means of a centrally attached marking 12 Then the horizontal alignment of the fastening frame 1 and its fixation takes place via the threaded spindles 11 attached foot plates 13 through the openings of which pegs 16 are driven into the ground. There are now the four support arms 2 to the Corners of the square mounting frame 1 initially loosely fastened with a threaded screw 17, so that they can be pivoted laterally. In front of the four construction pits 14, the support frames 3 are set up, with one side of the triangular support frame facing the construction pit points to the support frame 3 Support arms 2 with their forks 4 to lie. After the support arms 2 are adjusted to length and in exact position have been brought, as well as the horizontal alignment has taken place together with the support frame 3, the support arms 2 by tightening the Threaded screws 17 and fixed with the aid of clamping brackets 15 arranged on the support frame 3. Finally, the corner posts 9 are clamped in the holder 6 and the corresponding angle of inclination is set so that the corner posts are precisely positioned with their free ends protrude into the excavation, which is then filled with concrete. After the concrete has set the device is removed and the assembly of the mast base on the four corner posts can begin will.
