Abstract

Tower silos whose contents are removed using transport vehicles must be placed on a sub-construction which has sufficient headroom and width. The supports of this sub-construction are connected at their top ends by a horizontal ring girder which has to carry virtually the entire silo load. In order to better distribute the steel weight of the silo and thus to achieve considerable savings, in particular in the ring girder, it is proposed according to the invention to provide additional support by means of inclined rods (b) in the region of the tops of the supports (f). Short braces (d) are expediently arranged in the areas between the supports (f). <IMAGE>

Description

Die Erfindung bezieht sich auf eine Unterkonstruktion für ein Hochsilo nach dem Oberbegriff des Anspruches 1.The invention relates to a substructure for a high silo according to the preamble of claim 1.

Silos, deren Füllgut mit Transportfahrzeugen entnommen wird, müssen auf eine Unterkonstruktion gesetzt werden, die ausreichende Durchfahrtshöhe und -breite besitzt. Dies gilt sowohl für transportable Silos, die vornehmlich auf Baustellen aufgestellt werden, als auch insbesondere für ortsfeste Silos, wie Erzsilos, Kohlesilos, Schottersilos, Silos für Zuschlagstoffe, Getreidesilos, Gärfuttersilos und Silos für pulver- und staubförmige Schüttgüter. Die runde und zylindrische Form für die Silozellen wird bevorzugt. Hierzu hat man über den Umfang des Silos verteilt eine Anzahl von Stützen angeordnet, die das Silo am oberen Ende des Auslauftrichters unterstützen. Die Kopfenden der Stützen sind durch einen horizontalen Ringträger verbunden, der entweder einen Polygonzug bildet (z.B. Rechteck) oder einen Kreisring. Bei kreiszylindrischen Silos wird der Ringträger in der Regel durch eine geeignete Ausbildung des Überganges vom Kreiszylinder zum Auslauf trichter geschaffen und ist nicht sichtbar abgegrenzt. Auf diesen Ringträger entfällt ein erheblicher Anteil, häufig die gesamte Silolast.Silos, the contents of which are removed by transport vehicles, must be placed on a substructure that has sufficient clearance height and width. This applies both to portable silos, which are mainly installed on construction sites, and in particular to stationary silos, such as ore silos, coal silos, Ballast silos, silos for aggregates, grain silos, fermentation feed silos and silos for powdery and dusty bulk goods. The round and cylindrical shape for the silo cells is preferred. For this purpose, a number of supports have been arranged distributed over the circumference of the silo, which support the silo at the upper end of the discharge funnel. The head ends of the supports are connected by a horizontal ring carrier, which either forms a polygon (e.g. rectangle) or a circular ring. In circular cylindrical silos, the ring carrier is usually created by a suitable design of the transition from the circular cylinder to the outlet funnel and is not visibly delimited. This ring carrier accounts for a significant proportion, often the entire silo load.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, durch eine geeignete Konstruktion das Stahlgewioht und damit die Herstellungskosten zu vermindern. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The present invention is therefore based on the object of reducing the steel by means of a suitable construction and thus reducing the production costs. This object is achieved by the characterizing features of claim 1.

Die notwendigerweise große Feldweite des Ringträgers von Stütze zu Stütze wird durch Zwischenstützen unterteilt. Dies könnte geschehen durch einen Stabbogen mit aufgeständertem Ringträger. Einfacher ist es, im Kopfbereich der Stützen Schrägstäbe anzuordnen, womit die ursprüngliche Feldweite auf ein Drittel herabgesetzt wird.The necessarily large field width of the ring carrier from support to support is divided by intermediate supports. This could be done using a rod arch with a raised ring carrier. It is easier to arrange diagonal bars in the head area of the supports, which reduces the original field width to a third.

Die Stützen der bekannten Unterkonstruktionen für Hochsilos weisen eine vergleichsweise große Knicklänge auf, die eine entsprechende Bemessung der Stützen erfordert.The supports of the known substructures for high silos have a comparatively large buckling length, which requires a corresponding dimensioning of the supports.

Es wird deshalb in Weiterbildung der Erfindung vorgeschlagen, in den Feldern zwischen den Stützen Kreuzverbände oder vergleichbare Stabilisierungen anzuordnen. Diese können aber ein antimetrisches Knicken in radialer Richtung nicht verhindern, so daß nach einem weiteren Vorschlag der Erfindung die Stützen durch Horizontalstäbe gegen den Trichterauslauf des Silobehälters abgestützt werden. Damit ergibt sich in den Stützen für alle Knickrichtungen etwa die gleiche verkürzte Knicklänge.It is therefore proposed in a further development of the invention to arrange cross braces or comparable stabilizations in the fields between the supports. However, these cannot prevent an antimetric kink in the radial direction, so that, according to a further proposal of the invention, the supports are supported by horizontal bars against the funnel outlet of the silo container. This results in approximately the same shortened buckling length in the supports for all buckling directions.

Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben und erläutert.The invention is described and explained in more detail below with reference to exemplary embodiments shown in the drawing.

Der Ringträger, der den unteren Abschluß des Silobehälters darstellt, ist mit a bezeichnet; b sind die Schrägstäbe im Kopfbereich der Stützen f. In den Feldern zwischen den Stützen f sind Kreuzverbande d angeordnet. e bezeichnet den Auslauftrichter des Silobehälters. Das untere Endstück des Auslauftrichters e ist durch Horizontalstäbe c radial gegen die Stützen f abgestützt.The ring carrier, which represents the lower end of the silo container, is designated by a; b are the diagonal bars in the head area of the supports f. Cross braces d are arranged in the fields between the supports f. e denotes the discharge hopper of the silo container. The lower end of the discharge funnel e is supported radially against the supports f by horizontal bars c.
