Description
Es gibt nachgiebige Stempel für den Strebausbau, die mit den verschiedensten Schloßkon"struktionen arbeiten. Die Klemmwirkung wird durch keilartige Elemente erzeugt. Für St're.cken gibt es bisher Bauelemente, deren Nachgiebigkeit - durch Keile oder Verschraubung geregelt wird. Hierbei ist die gleichmäßige Nachgiebigkeit der einzelnen Stempel außerordentlich von der Sorgfalt, die beim Setzen der Baue angewendet werden muß, und von einer dauernden Überwachung abhängig. Ferner gibt es nachgiebige Ausbauformen, die durch Holzeinlagen eine Nachgiebigkeit ermöglichen. Der Umfang der, Nachgiebigkeit findet hier in der Stärke der Holzeinlagen seine Grenze, die meistens nicht ausreicht.There are compliant punches for longwall construction, those with the most varied Lock constructions work. The clamping effect is achieved by wedge-like elements generated. For St're.cken there are so far components whose flexibility - through Wedges or screw connections is regulated. Here is the uniform compliance the individual stamp is extraordinarily affected by the care that has been taken in setting the structures must be applied and dependent on continuous monitoring. Furthermore there there are flexible construction forms that allow flexibility through wooden inlays. The extent of the resilience is found here in the strength of the wooden inlays Limit that is usually not enough.
Der in Abb. i der Zeichnung_ dargestellte erfindungsgemäße Stempel besteht aus zwei Teilen, dem Oberstempel a und dem Unterstempel b: Der Oberstempel ist so bemessen, daß er in den Unterstempel genau hineinpaßt und dadurch eine Führung erhält. Unter dem Oberstempelfuß befindet sich ein weiches Metallstück c, das vorgebohrt ist.- In diese Bohrung schiebt sich ein Gleitkreuz d mit mehreren Schneiden, das am Fuß des Unterstempels befestigt wird und beim zunehmenden Druck durch Zerschneiden des weichen Metallstückes ein Einsinken des Oberstempels bewirkt. Das zerschnittene und unbrauchbar gewordene Metallstück ist maßlich sehr klein gehalten, so daß bei Erneuerung des Stempels kein großer Materialaufwand erforderlich ist. Abb. 2 veranschaulicht einen Streckenausbaurahmen, bestehend aus zwei Stempeln nach der Erfindung an den Streckenstößen und zwei Ausbaueisen e. .The punch according to the invention shown in Fig. I of the drawing consists of two parts, the upper punch a and the lower punch b: The upper punch is dimensioned so that it fits exactly into the lower punch and thereby receives a guide. Under the upper punch foot there is a soft piece of metal c, which is pre-drilled. A sliding cross d with several cutting edges pushes into this hole; The cut and unusable piece of metal is dimensionally very small, so that when the stamp is renewed, no great expenditure of material is required. Fig. 2 illustrates a route support frame, consisting of two stamps according to the invention on the route joints and two support bars e. .
Die Vorteile des Stempels nach der Erfindung für den Streckenausbau sind: i. Es kann eine Nachgiebigkeit bis zu 4o°/o -der Stempellänge erreicht werden.The advantages of the stamp according to the invention for road expansion are: i. A resilience of up to 40% of the punch length can be achieved.
2. Einsatzpunkt und Umfang der Nachgiebigkeit können bei der Herstellung der Stempel den Druckverhältnissen entsprechend beliebig festgelegt werden. Die Nachgiebigkeit tritt damit kurz vor dem Verformen der übrigen Bauelemente ein.2. The point of application and extent of the compliance can be during manufacture the stamp can be set as desired according to the pressure conditions. the Resilience occurs shortly before the other components are deformed.
3. Sämtliche Streckenausbaue besitzen gleiche Nachgiebigkeit und sind nicht von der Sorgfalt beim Setzen der Baue abhängig.3. All route extensions have the same flexibility and are does not depend on the care taken when placing the structures.
4. Die Gebirgslast wird von allen hintereinandergesetzten Bauen gleichmäßig getragen und kann sich entsprechend setzen. Zerrungen und Pressungen im Streckenprofil werden dadurch vermieden.4. The rock load will be the same for all buildings placed one behind the other worn and can sit down accordingly. Strains and pressures in the route profile are thereby avoided.
5. Durch die große Nachgiebigkeit wird das Einbringen eines zweiten Ausbaues vermieden.5. Due to the great flexibility, the introduction of a second Expansion avoided.
6. Nach dem Rauben, der Stempel können dieselben durch Einsatz . eines neuen Metallstückes immer wieder erneut zum Einsatz kommen.6. After stealing, the stamp can be used through the same. one new metal piece can be used again and again.
