Description
Kreisförmiger oder bogenförmiger eiserner Grubenausbau Bei eisernem Grubenausbau mit gleichsinnig ineinandergelegten Profilen kann es bei der durch die Nachgiebigkeit veränderlichen Spann- und Haftwirkung zwischen den Profilwangen vorkommen, daß die Profile an der Verbindungsstelle bzw. an dem der Strecke zugekehrten Profilende zu scharf ineinander packen, so daß die einzelnen Ausbaurahmen vorzeitig zu steif bzw. überhaupt starr werden. Die Folge ist dann eine vorzeitige und übermäßige Beanspruchung des Profilwerkstoffes, wenn der Gebirgsdruck noch weiter anwächst.Circular or arched iron pit lining Pit lining with profiles laid one inside the other in the same direction can be the case with the through the resilience variable tension and adhesive effect between the profile cheeks it can happen that the profiles at the connection point or at the one facing the route Pack the end of the profile too sharply into one another so that the individual expansion frames are prematurely become too stiff or stiff at all. The consequence is then premature and excessive Stress on the profile material when the rock pressure increases even further.
Um die übermäßige Beanspruchung des Profilwerkstoffes zu verhüten, hat man bereits Einlagen aus Holz zwischen die Böden der ineinanderliegenden Profile, also an deren Überlappungs- oder Verbindungsstelle eingebracht. Diese Einlagen konnten aber unter Umständen vorzeitig zerstört werden oder konnten verloren gehen, so daß dann doch kein Schutz gegen übermäßige Beanspruchung des Profilwerkstoffes vorhanden war. Auch war das Vorhandensein der Schutzeinlagen aus Holz an den Verbindungsstellen bei Kontrollen nicht immer festzustellen, jedenfalls nicht ohne weiteres sichtbar.To prevent excessive stress on the profile material, if you already have wooden inserts between the bottoms of the nested profiles, so introduced at their overlap or connection point. These deposits could but may be destroyed prematurely or could be lost, so that then there is no protection against excessive stress on the profile material was. There was also the presence of protective wooden inserts at the connection points not always detectable during controls, at least not easily visible.
Nach der Erfindung wird die Schutzeinlage durch metallene Gleitstücke in Form von Nasenkeilen gebildet, die an den Überlappungsstellen beiderseits zwischen die Bodengurtungen und über die Spannstellen hinausragend eingelegt sind. Nasenkeile sind als Spannkeile bei Grubenstempeln bekannt. Sie bilden aber hier weniger eine Gleit- und Schutzeinlage als ein Spannelement und dienen, in einem Schloß untergebracht, der Verspannung der beiden Stempelhälften miteinander. Im Gegensatz dazu steht ihre erfindungsgemäße Verwendung und Wirkung. Hier müssen die Nasenkeile die Arbeit der Gleitstücke aufnehmen, durch die das vorzeitige Starrwerden der nachgiebig arbeitenden Verbindung verhütet wird; sie müssen also wie Gleitkufen wirken. Außerdem dienen die Nasen durch Anlage am jeweiligen Profilende der Mitnahme, die Nasenkeile behalten dadurch bei der Wanderung der Profilenden ineinander ihren Einlegeort bei und die sichtbar vorstehenden Nasen bilden gleichzeitig die Markierung der Einlage.According to the invention, the protective insert is made of metal sliders formed in the form of nose wedges, which at the overlap points on both sides between the floor straps and protruding beyond the tie points are inserted. Nose wedges are known as clamping wedges in pit punches. But they are less of one here Sliding and protective insert as a clamping element and, housed in a lock, serve the bracing of the two die halves with one another. In contrast to this is hers Use and effect according to the invention. Here the nose wedges have to do the work of the Record sliders through which the premature rigidification of the flexible working Connection is prevented; so they have to act like skids. Also serve keep the noses by resting on the respective end of the profile of the entrainment, the nasal wedges thereby in the migration of the profile ends into each other their place of insertion and the Visibly protruding noses also mark the insert.
Zweckmäßig ist es, den Aufbau der Nasenkeile in abgesetzter Form zu wählen. Die Unterteilung in einen flachen prismatischen Teil und ein gegen die Nase zu anwachsendes Keilstück schafft zwischen den gebogenen Profilenden Luft und verhindert zwischen den Bögen eine volle Anlage und damit auch das zu feste Ineinanderpacken der Profile. Außerdem wird damit, bei Wahl entsprechenden Werkstoffes, eine gewisse Federung erreicht. Als Verbindung kann die bekannte schellenartige Spannungsverbindung verwendet werden, die das Ende des Nasenkeiles noch mit erfaßt, und durch deren Anspannung die geschilderte Wirkung erzielt wird. In der Zeichnung ist die Erfindung dargestellt. Die Abb. z ist die Längsansicht einer Verbindungsstelle, Abb. z ein Querschnitt dazu.It is useful to set up the nose wedges in a stepped manner Select. The division into a flat prismatic part and one against the nose wedge that is to grow creates air between the curved profile ends and prevents them a full system between the arches and thus the too tight packing into one another the profiles. In addition, if the appropriate material is selected, a certain Suspension achieved. The known clamp-like tension connection can be used as a connection be used, which still includes the end of the nose wedge, and through their Tension the effect described is achieved. In the drawing the invention is shown. Fig.z is a longitudinal view of a joint, Fig. Z is a cross-section.
Die Enden der beiden Rahmenstücke a und b werden in bekannter Weise durch die beispielsweise aus dem Schraubbügel c und der Flacheisenlasche ci! gebildete Spannungsverbindung ineinandergezogen, so daß die beiden Profile ineinandergleiten können. Zur Sicherstellung des Gleitens sind gemäß der Erfindung abgesetzte Nasenkeile zwischen die Böden der beiden Profile eingesetzt, die aus einem flachen prismatischen Teil e und dem Keilteil f bestehen und eine Nase g besitzen. Die Nase g hintergreift stets das zugehörige Pröfilende und sichert das Mitwandern des Nasenkeiles mit diesem. Die Nasenkeile können an nur einem oder an beiden Enden eingelegt sein, je nachdem die Verhältnisse dies erfordern. Am zweckmäßigsten ist bei Einzelanordnung die Einschaltung des Nasenkeiles mit der Nase an dem an der Streckeninnenseite liegenden Profil (a der Zeichnung). Diese Nasenkeile werden so lang ausgeführt, daß sie noch von der Spannungsverbindung erfaßt werden bzw. noch in deren Spannungsbereich liegen. Gleichzeitig mit der Regelung des Abstandes' der beiden Profile wird hier auf die einfachste Weise eine Sicherstellung des Gleitens der Profile erzielt und werden die Haft- und Spannungsverhältnisse in gleichbleibendem Zustande erhalten.The ends of the two frame pieces a and b are in a known manner by the example of the screw bracket c and the flat iron bracket ci! formed tension connection pulled into one another so that the two profiles can slide into one another. To ensure sliding, stepped nose wedges are used according to the invention between the bases of the two profiles, which consist of a flat prismatic part e and the wedge part f and have a nose g. The nose g always engages behind the associated profile end and ensures that the nose wedge moves with it. The nose wedges can be inserted at only one or at both ends, depending on the circumstances. In the case of individual arrangements, it is most useful to use the nose wedge with the nose on the profile on the inside of the track (a of the drawing). These nose wedges are made so long that they are still gripped by the tension connection or are still in its tension range. Simultaneously with the regulation of the distance between the two profiles, a guarantee of the sliding of the profiles is achieved in the simplest way and the adhesion and tension conditions are maintained in a constant state.
