Description

Die Erfindung betrifft ein Silo, umfassend mindestens eine Silozelle, wobei die Silozelle mehrere Wandelemente aufweist, wobei die Wandelemente an Knotenpunkten durch Hohlstützen miteinander in Verbindung stehen, wobei eine Hohlstütze mehrere miteinander verbundene Stützensegmente aufweist.The invention relates to a silo comprising at least one silo cell, wherein the silo cell has a plurality of wall elements, wherein the wall elements are interconnected at nodal points by hollow supports, wherein a hollow support has a plurality of interconnected support segments.

Silos oder Siloanlagen sind insbesondere aus mehreren Zellen aufgebaut. Bekannt sind in diesem Zusammenhang sogenannte Glattwand- und auch Dammwandsilos. Die Zellen haben häufig eine Höhe von 6 - 8 Metern.Silos or silos are in particular made up of several cells. Known in this context are so-called smooth wall and dam walls silos. The cells often have a height of 6 - 8 meters.

Eine Hohlstütze, die als Knotenpunkt zur Anbindung der Wandelemente dient, besteht aus mehreren Stützensegmenten, wobei nach Zusammenbau einer solchen Hohlstütze aus mehreren Stützensegmenten die Hohlstütze innen mit Beton ausgegossen wird.A hollow support, which serves as a node for connecting the wall elements, consists of a plurality of support segments, wherein after assembly of such a hollow support of several column segments, the hollow support is poured inside with concrete.

In diesem Zusammenhang sind aus der DE 18 28 833 U Stützen bekannt, die z. B. aus vier im Querschnitt trapezförmigen Stützensegmente als Achteck zusammengebaut sind. Andere Ausführungsformen zeichnen sich dadurch aus, dass abgewinkelte Bleche als Stützensegmente Verwendung finden, wobei die freien Enden der Stützensegmente an den Enden des benachbarten Stützensegmenten anliegend mit diesen verbunden sind.In this context are from the DE 18 28 833 U supports known, the z. B. are assembled from four trapezoidal in cross-section support segments as an octagon. Other embodiments are characterized in that angled sheets are used as support segments, wherein the free ends of the support segments are connected to the ends of the adjacent support segments adjacent thereto.

Die US 3,327,870 A zeigt ein Silo gemäβ des Oberbegriffs des Anspruchs 1 mit einer Stütze, die aus vier L-Profilen zusammengesetzt ist, wobei die Profile miteinander verschraubt sind.The US 3,327,870 A shows a silo according to the preamble of claim 1 with a support which is composed of four L-profiles, wherein the profiles are screwed together.

Die DE 14 34 855 A1 zeigt ebenfalls ein Silo gemäβ des Oberbegriffs des Anspruchs 1 mit Konstruktionen von Stützen, die ähnlich zu denen der DE 18 28 833 U sind. Auch hier sind abgewinkelte Bleche als Stützensegmente vorgesehen, deren freie Enden aneinanderliegend miteinander verbunden sind.The DE 14 34 855 A1 Also shows a silo according to the preamble of claim 1 with constructions of supports similar to those of DE 18 28 833 U are. Again, angled plates are provided as a support segments whose free ends are connected to each other adjacent to each other.

Die Erstellung der Hohlstütze eines Silos oder einer Silozelle ist montagetechnisch mit einigen Problemen behaftet. Es wurde in diesem Zusammenhang bereits darauf hingewiesen, dass Silobehälter oder Silozellen eine Höhe von 6 - 8 Metern aufweisen können. Wie bereits ausgeführt, werden die Hohlstützen aus einzelnen Stützensegmenten zusammengebaut. In diesem Zusammenhang ist nun bekannt, die Stützensegmente miteinander zu verschrauben. Zur Herstellung solcher Schraubverbindungen innerhalb der Hohlstütze verbietet es sich allerdings, die Hohlstütze länger als etwa 1,20 Meter zu gestalten, da eine Länge von 1,20 m etwa der Länge entspricht, die der Mensch mit seinem Arm durchgreifen kann, um bei der Verschraubung die Muttern zu halten. Hieraus wird deutlich, dass zur Erstellung einer Hohlstütze mit einer Länge von etwa 8 Metern, diese in eine Mehrzahl von Abschnitten zu unterteilen ist, die jeweils für sich erstellt und untereinander durch entsprechende Horizontalstöße verbunden werden müssen.The preparation of the hollow support of a silo or a silo cell is technically subject to mounting problems. It has already been pointed out in this connection that silo containers or silo cells can have a height of 6 to 8 meters. As already stated, the hollow columns are assembled from individual column segments. In this context, it is now known to screw the support segments together. For the production of such screw within the hollow support, however, it makes it impossible to make the hollow support longer than about 1.20 meters, since a length of 1.20 m corresponds approximately to the length of the man with his arm can pass through to keep the nuts in the screwing. From this it is clear that to create a hollow support with a length of about 8 meters, this is divided into a plurality of sections, each created by itself and must be connected to each other by corresponding horizontal joints.

Als weiterer Stand der Technik ist in diesem Zusammenhang ebenfalls zur Erstellung von Hohlstützen bekannt, die einzelnen Stützensegmente jeweils im Endbereich über ihre Länge nach innen kreisbogenförmig zu umbörteln. Als dann wird über die kreisbogenförmige Umbörtelung zweier benachbarter Stützensegmente eine korrespondierend hierzu ausgebildete Klammer geschoben, die ebenfalls zu beiden Seiten eine kreisbogenförmige Umbörtelung aufweist, sodass sich im Endbereich eines jeden Stützensegmentes ein Auge ergibt, wobei in die beiden kreisförmigen Augen zur Verbindung zweier Stützensegmente zwei Stangen eingeschlagen werden, mit denen die Klammer gegenüber den Enden der beiden Stützensegmente verspannt wird. Problematisch hieran ist, dass sich solche Stangen über eine Länge von mehreren Metern nicht durch das kreisförmige Auge schlagen lassen. Das heißt, auch mit diesem Stand der Technik besteht nicht die Möglichkeit der Herstellung von durchgängigen Hohlstützen in einer Länge von mehreren und hier insbesondere von bis zu 8 Metern.As a further prior art is also known in this context for the preparation of hollow columns, umbörteln the individual support segments in each case in the end over its length inwardly circular arc. As then a corresponding thereto formed clamp is pushed over the arcuate Umbörtelung two adjacent columns segments, which also has a circular arc Umbörtelung on both sides, so that in the end of each column segment results in an eye, in the two circular eyes for connecting two columns segments two rods be hammered, with which the bracket opposite the ends of the two support segments is braced. The problem with this is that such rods over a length of several meters can not be hit by the circular eye. That is, even with this prior art, there is no possibility of producing continuous hollow columns in a length of several and in particular of up to 8 meters.

Des Weiteren wäre die Verwendung von sogenannten Anschweißmuttern auf der Innenseite der Stützensegmente denkbar. Derartige Anschweißmuttern weisen aufgrund der erforderlichen Schweißeignung nicht die Festigkeitswerte auf, die für eine Schraubverbindung im Silobehälter erforderlich sind.Furthermore, the use of so-called weld-on nuts on the inside of the support segments would be conceivable. Due to the required weldability, such weld-on nuts do not have the strength values required for a screw connection in the silo container.

Denkbar wäre ebenfalls die Verwendung von sogenannten Käfigmuttern; eine Käfigmutter zeichnet sich dadurch aus, dass eine solche Mutter als Vierkantmutter in einem Metallkäfig gelagert ist, wobei der Metallkäfig nach Außen abgewinkelte Füße aufweist, die das eine der beiden Bleche, die durch die Schraubverbindung miteinander verbunden werden sollen, im Bereich der Bohrung zur Aufnahme der entsprechenden Schraube hintergreift. Das bedeutet, dass die beiden zu verbindenden Bleche im Bereich der Füße des Metallkäfigs nicht plan aufeinander liegen, sondern durch die klauenförmigen Füße im Bereich der Bohrung einen Abstand zueinander aufweisen. Insofern lässt sich eine solche Verbindung statisch nicht nachweisen.Also conceivable would be the use of so-called cage nuts; a cage nut is characterized in that such a nut is mounted as a square nut in a metal cage, wherein the metal cage has outwardly angled feet, which are the one of the two sheets to be connected by the screw, in the region of the bore for receiving behind the corresponding screw. This means that the two sheets to be joined in the region of the feet of the metal cage are not flat on each other, but by the claw-shaped feet in the bore have a distance from each other. In this respect, such a connection can not be statically proven.

Die der Erfindung zugrunde liegende Aufgabe besteht demzufolge darin, durchgehende Hohlstützen in nahezu beliebiger Länge herzustellen, ohne dass die Hohlstützen und damit die einzelnen Stützensegmente aus Montagegründen in der Länge unterteilt werden müssen.The object underlying the invention is therefore to produce continuous hollow columns in almost any length, without the hollow columns and thus the individual columns segments for assembly reasons in length must be divided.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass jedes Stützensegment eine frei in Richtung des Innenraums der Hohlstütze ragende abgewinkelte Lasche aufweist, wobei an der Lasche eine Halterung zur Aufnahme einer Mehrzahl von Schrauben oder Muttern als Teil einer Schraubverbindung zur Erstellung der Hohlstütze aus mehreren Stützensegmenten angeordnet ist. Im Einzelnen ist in diesem Zusammenhang vorgesehen, dass die Hohlstütze als sechseckige oder achteckige Hohlstütze ausgebildet ist, wobei die sechseckige Hohlstütze durch drei und die achteckige durch vier Stützensegmente gebildet ist. Ein jedes Stützensegment umfasst einen Wandanschlusssteg und zwei Verbindungsschenkel zur Verbindung mit dem jeweils benachbarten Stützensegment, wobei jeweils ein Verbindungsschenkel eines Stützensegments die frei in Richtung auf den Innenraum der Hohlstütze ragende abgewinkelte Lasche zur Aufnahme der Halterung aufweist. Mit der Erfindung ist nunmehr eine sogenannte verdeckte Verschraubung der einzelnen Stützensegmente zur Bildung einer Hohlstütze möglich, und zwar über eine beliebige Länge, da die Halterung zur Fixierung beispielsweise der Muttern auf der Innenseite der Hohlstütze sich als eine verlorene Halterung darstellt. Insbesondere liegen bei dieser Konstruktion die zu verbindenden Stützensegmente im Bereich ihrer Schraubverbindung plan aufeinander auf.To achieve the object, the invention proposes that each support segment has a projecting freely in the direction of the interior of the hollow support angled tab, wherein arranged on the tab a holder for receiving a plurality of screws or nuts as part of a screw to create the hollow support of a plurality of columns segments is. Specifically, it is provided in this context that the hollow support is formed as a hexagonal or octagonal hollow support, wherein the hexagonal hollow support is formed by three and the octagonal by four column segments. Each support segment comprises a wall connection web and two connecting legs for connection to the respectively adjacent support segment, wherein in each case a connecting leg of a support segment has the freely projecting in the direction of the interior of the hollow support angled tab for receiving the holder. With the invention, a so-called concealed screwing the individual support segments to form a hollow support is now possible over an arbitrary length, since the holder for fixing, for example, the nuts on the inside of the hollow support is a lost holder. In particular, in this construction, the support segments to be connected in the region of their screw flat on each other.

Vorteilhafte Merkmale und Ausbildungen zu der Erfindung ergeben sich aus den Unteransprüchen.Advantageous features and embodiments of the invention will become apparent from the dependent claims.

So ist insbesondere vorgesehen, dass sich die Halterung im Wesentlichen über die gesamte Länge des Stützensegmentes erstreckt, das heißt, dass über die Länge der Stütze eine beliebige Anzahl von Schraubverbindungen vorgesehen sein kann. Im Einzelnen ist nach einem besonders vorteilhaften Merkmal vorgesehen, dass die Halterung als Winkelschiene ausgebildet ist, wobei die Winkelschiene mit einem Schenkel an der Lasche durch beispielsweise eine Verschraubung befestigt ist, und der andere Schenkel der Aufnahme der Muttern der Mehrzahl an Schraubverbindungen dient.Thus, it is provided in particular that the holder extends substantially over the entire length of the support segment, that is, over the length of the support, an arbitrary number of screw connections can be provided. In particular, it is provided according to a particularly advantageous feature that the holder is designed as an angle rail, wherein the angle rail with a leg on the tab through For example, a screw is attached, and the other leg of receiving the nuts of the plurality of screw is used.

Der Schenkel der Winkelschiene, der der Aufnahme der Muttern dient, verläuft parallel zu den einander überlappenden Verbindungsschenkeln zweier Stützensegmente, wobei dieser Schenkel eine Mehrzahl von Öffnungen zur Aufnahme von Muttern aufweist. Hierbei ist insbesondere vorgesehen, dass die Öffnungen in dem Schenkel der Winkelschiene vieleckig und insbesondere die jeweilige Mutter klemmend aufnehmend ausgebildet sind, um zum einen zu gewährleisten, dass sich beim Eindrehen der Schraube die Mutter nicht mit dreht, und zum anderen die Mutter zum Zwecke der Montage in der Öffnung der Winkelschiene fixiert ist.The leg of the angle rail, which serves to receive the nuts, runs parallel to the overlapping connecting legs of two support segments, said leg having a plurality of openings for receiving nuts. In this case, it is particularly provided that the openings in the leg of the angle rail polygonal and in particular the respective mother are formed clampingly receiving to ensure on the one hand that the nut does not rotate when screwing the screw, and on the other hand, the mother for the purpose of Mounting is fixed in the opening of the angle rail.

In diesem Zusammenhang weisen nach einem besonders vorteilhaften Merkmal der Erfindung die Muttern zur Aufnahme durch die vieleckig ausgebildeten Öffnungen jeweils einen Flansch auf, wobei die jeweilige Mutter mit dem Flansch an der entsprechenden Wandung des Stützensegmentes und hier insbesondere des Verbindungsschenkels anliegt. In diesem Zusammenhang bietet sich insbesondere die Verwendung sogenannter Rippmuttern an, wobei durch den Flansch die Mutter gegen Herausfallen gesichert ist. Gegebenenfalls ist auch denkbar, die Mutter in der vieleckigen Öffnung durch Verkleben gegen Herausfallen zu sichern.In this context, according to a particularly advantageous feature of the invention, the nuts for receiving through the polygonal openings each have a flange, wherein the respective nut rests with the flange on the corresponding wall of the support segment and in particular of the connecting leg. In this context, in particular, the use of so-called rib nuts, which is secured by the flange, the mother against falling out. Optionally, it is also conceivable to secure the nut in the polygonal opening by gluing against falling out.

Gemäß Figur 2 weist der mit 1 bezeichnete Silo mehrere sechseckige Zellen 2 auf, wobei eine solche Zelle 2 mehrere Hohlstützen 10 aufweist, die als Knoten zur Verbindung der einzelnen Wandelemente 5 dienen.According to FIG. 2 For example, the silo denoted by 1 has a plurality of hexagonal cells 2, such a cell 2 having a plurality of hollow columns 10 which serve as nodes for connecting the individual wall elements 5.

Gegenstand der Erfindung ist nunmehr die Ausbildung der Hohlstützen 10 und zwar als sechseckige (Figur 3) und als achteckige Hohlstütze (Figur 4). In Bezug auf die Erfindung sind beide Stützen gleich ausgebildet. Insofern sind auch die Bezugszeichen gleich.The invention is now the formation of the hollow columns 10 as a hexagonal ( FIG. 3 ) and as an octagonal hollow support ( FIG. 4 ). With regard to the invention, both supports are identical. In this respect, the reference numerals are the same.

Die Hohlstütze 10 gemäß Figur 3 und Figur 4 besitzt drei bzw. vier Stützensegmente 11. Ein jedes Stützensegment 11 umfasst einen Wandanschlusssteg 12, wobei sich an den Wandanschlusssteg zu beiden Seiten im Winkel α von ca. 135 Grad für die Achteckstütze (Sechseckstütze ca. 120 Grad) Verbindungsschenkel 13 erstrecken, wobei die Verbindungsschenkel 13 der Verbindung mit dem jeweils benachbarten Verbindungsschenkel des Stützensegmentes dienen. Zur Verbindung ist die insgesamt mit 15 bezeichnete Schraubverbindung vorgesehen. Im Bereich der Schraubverbindung 15 überlappen sich die Verbindungsschenkel zweier benachbarter Stützensegmente, wie sich dies unmittelbar in Anschauung von Figur 5 ergibt. Darüber hinaus besitzt der innenliegende Verbindungsschenkel der beiden einander überlappenden Verbindungsschenkel, die im Winkel von 90 Grad frei in das Innere der Hohlstütze ragende abgewinkelte Lasche 17. Die Lasche 17 dient der Aufnahme der Halterung 20, die als Winkelschiene ausgebildet ist (Figur 6). Die Winkelschiene ist mit ihrem Schenkel mit der Lasche 17 vorteilhaft verschraubt und erstreckt sich über die Länge der Lasche 17, mithin auch über die gesamte Länge der Hohlstütze. Die Winkelschiene 20 zeigt in ihrem Schenkel 21 mehrere hintereinander angeordnete vieleckige Öffnungen 24, die jeweils der Aufnahme der Mutter 15a der Schraubverbindung 15 mit der Inbusschraube 16 dienen. Die Mutter 15a ist als sogenannte Rippmutter ausgebildet, und besitzt einen Flansch 15b, mit welchem die Mutter an der Innenwandung des Verbindungsschenkels anliegt, wie sich dies ebenfalls in Anschauung von Figur 5 ergibt. Wesentlich hierbei ist, dass in der Höhe des Flansches 15b der Schenkel 21 der Winkelschiene 20 beabstandet zur Innenseite des Verbindungsschenkels 13 verläuft.The hollow support 10 according to FIG. 3 and FIG. 4 has three or four support segments 11. Each support segment 11 comprises a wall connection web 12, wherein extending to the wall connection web on both sides at an angle α of about 135 degrees for the octagonal support (hexagonal support about 120 degrees) connecting legs 13, wherein the connecting leg Serve 13 of the connection with the respective adjacent connecting leg of the support segment. To connect the designated total of 15 screw is provided. In the area of the screw connection 15, the connecting legs of two adjacent column segments overlap, as can be seen directly from the perspective of FIG FIG. 5 results. In addition, the inner connecting leg of the two overlapping connecting legs, which projects at an angle of 90 degrees freely into the interior of the hollow support projecting angled tab 17. The tab 17 serves to receive the holder 20, which is designed as an angle rail ( FIG. 6 ). The angle rail is advantageously screwed with its leg with the tab 17 and extends over the length of the tab 17, thus also over the entire length of the hollow support. The angle rail 20 shows in its leg 21 a plurality of polygonal openings 24 arranged one behind the other, each of which serves to receive the nut 15a of the screw connection 15 with the Allen screw 16. The nut 15a is formed as a so-called Rippmutter, and has a flange 15b, with which the nut rests against the inner wall of the connecting leg, as is also in the view of FIG. 5 results. It is essential here that, in the height of the flange 15b, the leg 21 of the angle rail 20 extends at a distance from the inside of the connecting leg 13.

Für die Montage der Hohlstütze wird als Halterung für die Muttern 15a der Schraubverbindung nun so vorgegangen, dass die jeweilige Winkelschiene 20 mit dem Schenkel 22 an der Lasche 17 angeschraubt wird. Als dann werden in die vieleckigen Öffnungen 24 die Muttern 15a klemmend eingesetzt, wobei dann die einzelnen Stützensegmente 11 zusammengesetzt werden und dann mittels der Schrauben 16 die Verbindungsschenkel 13 der Stützensegmente 11 zur Bildung der Hohlstütze verbunden werden. Hiernach kann die Hohlstütze mit Beton ausgegossen werden.For the assembly of the hollow support is now carried out as a holder for the nuts 15a of the screw, that the respective angle rail 20 is screwed to the leg 22 on the tab 17. As then the nuts 15a are inserted by clamping into the polygonal openings 24, in which case the individual support segments 11 are assembled and then, by means of the screws 16, the connecting legs 13 of the support segments 11 are connected to form the hollow support. Thereafter, the hollow support can be poured with concrete.
