Description
Ausbauelement für den Streb-und Streckenausbau aus Stahl oder Leichtmetall für den Bergbau Die Erfindung bezieht sich auf ein Ausbauelement für den Streb- und Streckenausbau aus Stahl oder Leichtmetall mit einer offenen Ouerschnittsform. Sie bezweckt die Aufnahme der Verdrehungsbeanspruchuncr n ge bei Ausbauelementen für den Streb- und Streckenausbau.Extension element for longwall and route extension made of steel or light metal for mining The invention relates to an expansion element for the longwall and track extension made of steel or light metal with an open cross-sectional shape. Its purpose is to absorb the torsional stresses in extension elements for longwall and route expansion.
Die Ausbauelemente bei modernem Streb- und Streckenausbau in Stahl oder Leichtmetall werden sowohl als Ausbaukappen als auch als Streckenbögen außer auf Biegung auch auf Verdrehung beansprucht. Um diese Verdrehungsbeanspruchungen aufzunehmen, ist bereits der Vorschlag gemacht worden, bei einem Ausbauelernent mit I-förmigem Querschnitt am Steg oder an den Flanschen Verstärkungen anzubringen. Außerdem wurden bei Hohlprofilen, d. h. Ausbauelementen mit geschlossener Ouerschnittsform, Innenverstärkungen in Form von zusätzlichen Stegen vorgesehen. Diese Hohlprofile weisen jedoch ein erhebliches Mehrgewicht auf, was besonders als Nachteil für Untertagebetriebe im Bergbau zu werten ist.The extension elements in modern longwall and line support in steel or light metal are stressed both as extension caps and as line arches, apart from bending and twisting. In order to absorb these torsional stresses, the proposal has already been made to attach reinforcements to the web or to the flanges of an expansion element with an I-shaped cross-section. In addition, in the case of hollow profiles, i.e. H. Expansion elements with a closed cross-section, internal reinforcements in the form of additional webs provided. However, these hollow profiles have a considerable additional weight, which is to be assessed as a particular disadvantage for underground operations in mining.
Es sind ferner an dem Steg von I-Profilen Warzen oder Sicken angebracht worden mit dem Zweck, die Abstandsbolzen zwischen den Ausbauten zu halten. Eine durchlaufende Verstärkung wird mit diesen Warzen oder Sicken nicht erzielt. Aus dem Hochbauwesen sind auch I-Träger bekannt, deren Steg ausgehaucht ist. Durch diese Verformung des Steges verliert der Träger an Widerstandsmoment, so daß eine solche Ausbauchung des Steges für die Zwecke unter Tage ungeeignet ist. Auf dem gleichen Gebiet sind Stahlleichtbauträger bekannt, die aus verformten Curten und in wechselnder Richtung geführtem Steg aus mehreren U-förmig gebogenen Blechen zusammengesetzt sind. Das Zusammensetzen erfolgt einseitig unter dem Gesichtswinkel der Verbesserung des Widerstandes gegen Durchbiegen dieser Leichtbauträger. Ähnliche Leichtträger sind aus dem Flugzeugbau bekannt. Für einen Einsatz unter Tage sind alle diese Leichtbanträger gänzlich ungeeignet.There are also lugs or beads attached to the web of I-profiles with the purpose of holding the spacer bolts between the extensions. One continuous reinforcement is not achieved with these warts or beads. the end I-beams are also known in building construction, the web of which is breathed out. Through this Deformation of the web loses the carrier's moment of resistance, so that such Bulging of the bridge is unsuitable for underground purposes. On the same In the area, lightweight steel construction girders are known, which are made from deformed Curten and in alternating Direction of led web composed of several U-shaped bent sheets are. The assembly is carried out on one side from the point of view of improvement the resistance to bending of these lightweight beams. Similar light beams are known from aircraft construction. All of these light beam carriers are suitable for use underground totally unsuitable.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Ausbauelernent für den Streb- und Streckenausbau in Stahl oder Leichtmetall mit offener Querschnittsform zu schaffen, das durch besonders ausgebildete und angebrachte Verstärkungen sowohl die Biegungsals auch besonders die Verdrehungsbeanspruchungen aufnehmen kann.The invention is therefore based on the object of an expansion element for longwall and line support in steel or light metal with an open cross-sectional shape to create that through specially trained and attached reinforcements both the bending as well as especially the torsional stresses can absorb.
Das aus Stahl oder Leichtmetall bestehende Ausbauelernent mit offener Querschnittsform wird erfindungsgemäß so ausgebildet, daß ein in Längsrichtung des Elementes verlaufendes, wellen- bis zickzackförmig oder ähnlich gebogenes Band lotrecht oder ,vaa-erecht zwischen zwei Gurten befestigt ist, wobei dessen '\#'ellenhöhe bzw. Breite et-wa der Gurtbreite entspricht. Das Band wird an seinen Höchst- und Tiefpunkten mit den Flanschen oder Gurten des Ausbauprofils verbunden, so daß eine Art Fachwerkträger gebildet ist.The expansion element made of steel or light metal with an open Cross-sectional shape is designed according to the invention so that a in the longitudinal direction of the Element running, wavy to zigzag or similarly curved band perpendicular or, vaa-right between two straps, where the '\ #' is ellenhöhe or width roughly corresponds to the belt width. The tape is at its peak and Low points connected to the flanges or belts of the extension profile, so that a Type of truss is formed.
Durch diese erfindungsgenläße Ausbildung des Ausbauelementes erhält man eine auf Biegung und Verdrehung tragfähige, steife und leichte Ausführung, die insbesondere für Untertagebetriebe vorteilhafte Eigenschaften aufweist. Die Wellenform des Steges kann bei gepreßten Aluminiumkappen ohne Verteuerung der Herstellung erreicht werden. Der weitere Vorschlag der Erfindung, welcher sich auf die Ausbildung des Ausbauelementes als Fachwerkträger bezieht, beruht auf dem Prinzip der Zellenbauweise. Hierbei kann man außer dem wellenförmig ausgebildeten, zwischen die Flansche eingeschalteten Band auch einen zusätzlichen mittleren Steg anordnen.By this erfindungsgenläße training of the expansion element is obtained one has a rigid and light design that can bend and twist has advantageous properties in particular for underground operations. The waveform of the web can be achieved with pressed aluminum caps without making the production more expensive will. The further proposal of the invention, which relates to the training of the Expansion element as a truss, is based on the principle of cell construction. Here you can switch between the flanges in addition to the wave-shaped Also arrange an additional middle bar on the tape.
In der Zeichnung sind zwei Ausführungsbeispiele nach der Erfindung dargestellt.In the drawing are two embodiments according to the invention shown.
In den Abb. 1 bis 3 ist als Ausbauelement ein verdrehungssteifer Träger dargestellt. Die obere Gurtung bzw. der Oberflansch des Trägers ist in diesen Ab- bildungen mit 1 und der Unterflansch bzw. die untere Gurtung mit 3 bezeichnet. Das zwischen Oberfianschl und Unterflansch 3 eingeschaltete Band 2 wird erfindungsgemäß, wie aus den Abb. 2 und 3 ersichtlich ist, in Längsachsenrichtung des Ausbauelernentes wellen-oder zickzackförmig verformt ausgebildet, wobei in den Abb. 1 und 2 die über die Längsachse vorspringenden Teile des Bandes mit 2' bezeichnet sind. Die Verformung des Bandes 2 kann, wie in Abb. 2 dargestellt, gleichmäßig gewellt oder - wie aus Abb. 3 zu ersehen ist - in Zickzackform mit abgeflachten Zacken erfolgen.In Figs. 1 to 3 , a torsion-resistant carrier is shown as an extension element. The upper taping or the top flange of the carrier is formations in these waste designated by 1 and the bottom flange and the lower taping by 3. The belt 2 inserted between the upper flange and the lower flange 3 is, according to the invention, as can be seen from Figs. 2 and 3 , formed in a wave or zigzag shape in the direction of the longitudinal axis of the expansion element, with the parts of the belt projecting over the longitudinal axis in Figs. 1 and 2 are denoted by 2 '. The deformation of the band 2 can, as shown in Fig. 2, be uniformly corrugated or - as can be seen from Fig. 3 - take place in a zigzag shape with flattened prongs.
In Abb. 4 ist ein Träger dargestellt, bei dem das zwischen Oberflansch 1 und Unterflansch 3 eingeschaltete Band gleichlaufend und in keinem Winkel zu den Flanschen 1 und 3 stehend angeordnet ist. Bei dieser hier gegebenen Zellenbauweise ist das einge-ZD schaltete Band 4 an seinen Höchst- und Tiefpunkten 5 und 6 mit der oberen und unteren Gurtung 1 und 3 des Ausbauelementes verbunden.In Fig. 4 a carrier is shown in which the belt inserted between the upper flange 1 and the lower flange 3 is arranged in the same direction and not at any angle to the flanges 1 and 3 . In this cell construction given here, the on-ZD switched band 4 is connected at its highest and lowest points 5 and 6 with the upper and lower chords 1 and 3 of the extension element.
