Description
Die Erfindung betrifft ein Ausbauprofil für den Gruben- und Tunnelausbau, bestehend aus zwei I-Profilen, deren gestoßene Innenflansche unter Bildung eines Kastenprofils miteinander verbunden sind.The invention relates to an expansion profile for mining and tunneling, consisting of two I-profiles, the butted inner flanges of which are connected to form a box profile.
Für den Grubenausbau, insbesondere für den Streb- und Strekkenausbau, kennt man verschiedene Ausbauprofile, welche die Funktion von Kappen und Unterzügen erfüllen können. Dazu gehören bevorzugt Stegprofile, wobei Rinnenprofile jedoch regelmäßig als Streckenbögen eingesetzt werden. Im Zuge Ihres Einbaus müssen die Ausbauprofile entweder von Stempeln unterstützt oder unter Verwendung von Gebirgsankern mittels die Ausbauprofile untergreifenden Laschen gleichsam am Hangenden abgehängt werden. Die Verbindung der Ausbauprofile erfolgt im allgemeinen mittels ihre Stoßenden übergreifender und aussenliegender Laschen. Die zu setzenden Stempel stören ebenso wie die zu montierenden Laschen aus verschiedenen Gründen. Abgesehen vom Materialaufwand behindern die Stempel beispielsweise bei der Einrichtung von Auf- und Abhauen. Das Gleiche gilt für eine hinreichende Stempelunterstützung im Übergangsbereich vom Streb zur Strecke, insbesondere im Bereich des Maschinenteils, weil dort durch die Stempel der Raum für die Einrichtung der Antriebe von Förderer und Gewinnungsmaschine beengt wird. Endlich ist auch im Bereich des Streckenbegleitdammes das fortlaufende Setzen und Rauben von Stempeln zum Unterstützen von unterzugbildenden Ausbauprofilen aufwendig und umständlich. - Das Unterfangen von Ausbauprofilen und deren Verbindung mittels außenseitig anzuordnender Laschen stört, weil sich dann die Ausbauprofile nicht als Laufschienen für Geräte- und ggf. Maschinentransport heranziehen lassen.Various expansion profiles are known for mine construction, especially for longwall and longwall construction, which can fulfill the function of caps and beams. This preferably includes web profiles, but channel profiles are regularly used as route arches. In the course of your installation, the expansion profiles must either be supported by stamps or, using rock anchors, be hung from the hangers under the expansion profiles. The connection of the expansion profiles is generally carried out by means of overlapping and external tabs. The stamps to be placed, as well as the tabs to be mounted, are disruptive for various reasons. Apart from the cost of materials, the stamps hinder, for example, the establishment of stripping and stripping. The same applies to adequate stamp support in the transition area from the strut to the route, particularly in the area of the machine part, because there the space for setting up the drives of the conveyor and extraction machine is restricted by the stamp. Finally is in the area of the route accompanying dam, the continuous setting and robbing of stamps to support expansion profiles that form the girders complex and cumbersome. - The undertaking of removal profiles and their connection by means of brackets to be arranged on the outside is disruptive, because the removal profiles cannot then be used as running tracks for device and, if necessary, machine transport.
Ferner ist ein Ausbauprofil für den Gruben- und Tunnelausbau bekannt, welches einen I-förmigen, H-förmigen oder V-förmigen Querschnitt aufweist. Dieses Ausbauprofil besitzt endseitig Kupplungsplatten, die Kupplungsplatten weisen Bohrungen zum Anschluß benachbarter Ausbauprofile mit Hilfe von Schraubverbindungen auf. Ferner ist im mittleren Bereich ein zusätzlicher Führungskanal vorgesehen, der durch eine im Mittelsteg angeordnete zylindrische Wandung gebilde-t wird und zum Hindurchführen einer Ankerstange dient. Die Ankerstange muß auf der Profilunterseite mittels Tragplatte und Mutter festgelegt werden (vgl. FR 23 22 259). - Durch diese bekannten Maßnahmen sind die eingangs behandelten Probleme nicht maßgebend beeinflußt worden.Furthermore, an expansion profile for pit and tunnel expansion is known, which has an I-shaped, H-shaped or V-shaped cross section. This expansion profile has coupling plates at the end, the coupling plates have bores for connecting adjacent expansion profiles with the aid of screw connections. Furthermore, an additional guide channel is provided in the central area, which is formed by a cylindrical wall arranged in the central web and is used to pass an anchor rod. The anchor rod must be fixed on the underside of the profile using the support plate and nut (see FR 23 22 259). - The known problems have not been significantly influenced by these known measures.
Im übrigen kennt man eine Kastenprofilkappe aus zwei I-Profilen, deren den Kappenhohlraum oben und unten abschließende Flanschteile an der Stoßstelle miteinander verschweißt sind. Die den Rappenhohlraum abschließenden Flanschteile sind an ihrer Außenseite zur Stoßstelle hin einwärts geneigt. Dadurch will man erreichen, daß die leicht gewölbte Kopfplatte eines die Kappe stützenden Stempels die einander zugewandten Flanschenden der neiden I-Profile nicht berührt, sondern nur unterhalb der beiden Stege an den Flanschen anliegt. Dadurch wird die Last von der Kopfplatte mittig auf die Stege übertragen, so daß die Stege nur auf Druck beansprucht werden und folglich ein Schutz gegen Ausknicken oder Ausbeulen erreicht wird (vgl. GB 786 538).For the rest, a box profile cap is known from two I-profiles, the flange parts of which seal the cap cavity at the top and bottom are welded together at the joint. The flange parts closing off the Rappen cavity are inclined inwards on the outside towards the joint. The aim of this is to ensure that the slightly curved head plate of a stamp supporting the cap does not touch the facing flange ends of the jealous I-profiles, but only abuts the flanges below the two webs. As a result, the load is transferred from the top plate to the center of the webs, so that the webs are only subjected to pressure and consequently protection against buckling or bulging is achieved (cf. GB 786 538).
Der Erfindung liegt die Aufgabe zugrunde, ein Ausbauprofil für den Gruben- und Tunnelausbau der eingangs beschriebenen Art zu schaffen, welches unterstützungsfrei eingebaut werden kann, den endseitigen Anschluß weiterer Ausbauprofile ohne Außenflanschen ermöglicht und folglich als Laufschiene Verwendung finden kann.The invention has for its object to provide an expansion profile for the pit and tunnel expansion of the type described above, which can be installed without support, the end connection of other expansion profiles without external flanges and thus can be used as a track.
Diese Aufgabe löst die Erfindung bei einem gattungsgemäßen Ausbauprofil dadurch, daß das Kastenprofil in seinem oberen I-Flansch und in seinem unteren I-Flansch Montageausnehmungen aufweist, daß die Montageausnehmungen in vorgegebenen Abständen auf der Mittellängsachse der I-Flansche angeordnet sind, daß die oberen und unteren Montageausnehmungen sich in vertikaler Projektion zumindest überschneiden, daß die Montageausnehmungen als Langlöcher ausgebildet und in vertikaler Projektion symmetrisch zwischen den I-Stegen angeordnet sind, und daß die Außenflansche der I-Flansche als Lauffläche für Lastlaufwerke ausgebildet sind. - Nach Lehre der Erfindung wird ein Kastenprofil als Ausbauprofil verwirklicht, welches sich mittels Gebirgsanker, z. B. Spreizhülsenanker, Zementmörtelanker oder Klebeanker, am Gebirge und insbesondere am Hangenden einwandfrei befestigen läßt. Dazu können die eingebrachten Gebirgsanker durch die Montageausnehmungen hindurchgeführt werden. Folglich ist ein unterstützungsfreier bzw. stempelfreier Einbau des erfindungsgemäßen Ausbauprofils möglich, und zwar sowohl in Strecken- und Streblängsrichtung als auch -querrichtung. Hinzu kommt, daß ein außenlaschenfreier Anschluß mit einem benachbarten Ausbauprofil im Bereich der Stoßenden ermöglicht wird, weil sich die Anschlußmittel einerseits in den Hohlräumen der zu verbindenden Kastenprofile unterbringen lassen, andererseits nach dem Einsetzen in die Hohlräume über die Montageausnehmungen arretieren lassen. Soweit stempel- bzw. unterstützungsfreier Einbau des erfindungsgemäßen Ausbauprofiles erfolgt, steht nunmehr hinreichender Raum für den ungestörten Einbau von Förderund Gewinnungseinrichtungen beim Herstellen von Auf- und behauen sowie beim Einrichten von Maschinenställen zur Verfügung, während beim Herstellen von Streckenbegleitdämmen das Setzen und Rauben von Stempeln entfällt. Darüber hinaus können erfindungsgemäße Ausbauprofile übereinander angeordnet und im Bereich der Montageausnehmungen arretiert werden, gleichgültig ob es sich um kreuzende Ausbauprofile oder gleichgerichtete Ausbauprofile handelt. Auch der Einsatz von Aufhängevorrichtungen in die unteren Montageausnehmungen des zentrisch geankerten Au:bauprofils ist möglich. Weiter bereitet der Anschluß an Streckenausbauprofile und insbesondere Streckenbögen - bevorzugt im Übergangsbereich vom Streb zur Strecke - keine Probleme. Stets ist ein einwandfreies Sichern der Ausbauräume durch stempelfreien bzw. unterstützungsfreien Einbau des erfindungsgemäßen Ausbauprofils als Kappe oder Unterzug mittels Gebirgsanker gewährleistet. Die Langlöcher gewährleisten das erforderliche Bewegungsspiel für das Hindurchführen der Ankerstäbe der bereits gesetzten Anker im Zuge des Einbaus des Ausbauprofils. Dabei kann der Abstand zwischen den Montageausnehmungen doppelt so groß wie ihre Länge sein. Ferner erfüllt das erfindungsgemäße Ausbauprofil die Funktion einer Laufschiene. Das ist deshalb möglich, weil sich das erfindungsgemäße Ausbauprofil unter Verzicht auf Außenlaschen im Bereich seiner Stoßenden mit weiteren Ausbauprofilen verbinden läßt, also zu einer ununterbrochenen Laufschiene ohne störende Verbindungselemente zusammenbauen läßt. Daraus resultiert zugleich die Möglichkeit, an dem erfindungsgemäßen Ausbauprofil bzw. der entstehenden Laufschiene eine Bohrvorrichtung mit einer Ankersetzvorrichtung zu verfahren, die dadurch stets an Ort und Stelle für das Setzen von Gebirgsankern zur Verfügung stehen. Ebenso lassen sich beispielsweise Dammbaubegrenzungselemente zum Errichten einer Blasversatzwand od. dgl. Einrichtungen an der fortlaufend verlegten Laufschiene mittels der Lastlaufwerke verfahren, so daß sich das erfindungsgemäße Ausbauprofil zugleich für Streckenauffahrung verwenden läßt.This object is achieved by the invention in a generic expansion profile in that the box profile has mounting recesses in its upper I-flange and in its lower I-flange, that the mounting recesses are arranged at predetermined intervals on the central longitudinal axis of the I-flanges, that the upper and lower mounting recesses at least overlap in vertical projection, that the mounting recesses are formed as elongated holes and are arranged symmetrically in vertical projection between the I-bars, and that the outer flanges of the I-flanges are designed as a tread for load drives. - According to the teaching of the invention, a box profile is realized as an expansion profile, which is by means of rock anchors, for. B. expansion sleeve anchors, cement mortar anchors or adhesive anchors, can be properly attached to the mountains and especially on slopes. For this purpose, the rock anchors introduced can be passed through the mounting recesses. Consequently, a support-free or Stamp-free installation of the expansion profile according to the invention is possible, both in the longitudinal and longitudinal direction as well as in the transverse direction. In addition, an outer bracket-free connection with an adjacent expansion profile in the area of the butt ends is made possible because the connection means can be accommodated in the cavities of the box profiles to be connected on the one hand, and can be locked in place via the mounting recesses after insertion into the cavities. Insofar as the expansion profile according to the invention is installed without stamps or support, there is now sufficient space for the undisturbed installation of production and extraction facilities for the manufacture of construction and trenching as well as for the installation of machine stables, while the setting and stealing of stamps is no longer required when producing line accompanying dams . In addition, expansion profiles according to the invention can be arranged one above the other and locked in the area of the mounting recesses, irrespective of whether they are crossing expansion profiles or rectified expansion profiles. It is also possible to use suspension devices in the lower mounting recesses of the centrally anchored construction profile. Furthermore, the connection to route expansion profiles and in particular route arches - preferably in the transition area from the strut to the route - poses no problems. Flawless securing of the expansion spaces is always ensured by stamp-free or support-free installation of the expansion profile according to the invention as a cap or beam using rock anchors. The elongated holes ensure the necessary play for the passage of the anchor rods of the anchors that have already been placed in the course of installing the expansion profile. The The distance between the mounting recesses must be twice as long as their length. Furthermore, the expansion profile according to the invention fulfills the function of a running rail. This is possible because the expansion profile according to the invention can be connected to other expansion profiles in the region of its butt ends without the use of external brackets, that is to say it can be assembled to form an uninterrupted running rail without disruptive connecting elements. This also results in the possibility of moving a drilling device with an anchor-setting device on the expansion profile according to the invention or the resulting running rail, which are thus always available on site for setting rock anchors. Likewise, dam construction limiting elements for erecting a blower offset wall or the like. Devices on the continuously installed running rail can be moved by means of the load drives, so that the expansion profile according to the invention can also be used for driving on a route.
Weitere erfindungswesentliche Merkmale sind im folgenden aufgeführt. So sieht die Erfindung vor, daß die Innenflansche des oberen und unteren I-Flansches schmaler als die Außenflansche, z. B. halb so breit ausgebildet sind. Dadurch läßt sich ein Ausbauprofil verwirklichen, welches verhältnismäßig schmal baut, obwohl es sich um ein Kastenprofil handelt. Außerdem kann das erfindungsgemäße Ausbauprofil auch in herkömmlicher Weise als Kappe oder Unterzug eingesetzt werden, also mit Unterstützung durch Stempel, falls das unbedingt erforderlich sein sollte. Bevorzugt ist jedoch ein Abhängen mittels Gebirgsanker vorgesehen. Aus diesem Grund lehrt die Erfindung, daß die oberen und unteren Montageausnehmungen als deckungsgleiche Ausnehmungen fluchten, wodurch das Durchführen der Ankerstäbe durch Montageausnehmungen erleichtert wird. Die Sicherung des Ausbauprofils erfolgt mittels einer Ankerplatte und Ankermutter. Um auch eine Unterstützung mittels herkömmlicher Stempel zu ermöglichen, sind in an sich bekannter Weise die äußeren Längskanten der Außenflansche in vorgegebenen beständen unter Bildung von Nocken mit Ausnehmungen versehen, in welche also die kronenartigen Stempelköpfe eingreifen können. Endlich lehrt die Erfindung, daß endseitig in das Rastenprofil des erfindungsgemäßgen Ausbauprofils um horizontale und/oder vertikale Achsen abwinkelbare Kupplungsstücke einsetzbar sind und im Bereich der Montageausnehmungen sowie abwinkelbaren Getriebe arretierbar sind. Dadurch läßt sich das erfindungsgemäße Ausbauprofil auch als starr kuppelbare und vorpfändbare Gelenkkappe einsetzen.Further features essential to the invention are listed below. So the invention provides that the inner flanges of the upper and lower I-flange narrower than the outer flanges, for. B. are formed half as wide. This makes it possible to realize an expansion profile that is relatively narrow, even though it is a box profile. In addition, the expansion profile according to the invention can also be used in a conventional manner as a cap or beam, ie with the support of a stamp, if this should be absolutely necessary. However, a suspension by means of rock anchors is preferably provided. For this reason, the invention teaches that the upper and lower mounting recesses are aligned as congruent recesses, which facilitates the passage of the anchor rods through mounting recesses becomes. The expansion profile is secured using an anchor plate and anchor nut. In order to enable support by means of conventional stamps, the outer longitudinal edges of the outer flanges are provided in a known manner with recesses to form cams, in which the crown-like stamp heads can engage. Finally, the invention teaches that coupling parts which can be angled about horizontal and / or vertical axes can be inserted at the end into the detent profile of the expansion profile according to the invention and can be locked in the region of the mounting recesses and angled transmission. As a result, the expansion profile according to the invention can also be used as a rigidly connectable and attachable joint cap.
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, daß ein Ausbauprofil für Gruben- und Tunnelausbau verwirklicht wird, welches unterstützungsfrei, also unter Verzicht auf Stempel, Außenlaschen od. dgl. Unterfangungsmittel, eingebaut werden kann. Dieser unterstützungsfreie Einbau gelingt mittels Gebirgsanker, so daß das erfindungsgemäße Ausbauprofil praktisch an dem Hangenden abgehängt wird. Selbstverständlich ist ein Einbau auf dem Liegenden ebenfalls möglich. Aus dem unterstütztungsfreien und dennoch sicheren Einbau des erfindungsgemäßen Ausbauprofils als Kappe oder Unterzug resultiert Raumfreiheit bzw. Bewegungsfreiheit beim Erstellen sowie Einrichten von Aufhauen und Abhauen ebenso wie imThe advantages achieved by the invention are essentially to be seen in the fact that an expansion profile for pit and tunnel expansion is realized, which can be installed without support, ie without the use of punches, outer plates or the like. This support-free installation is achieved by means of rock anchors, so that the expansion profile according to the invention is practically suspended from the slope. Of course, installation on the bed is also possible. The support-free and yet safe installation of the expansion profile according to the invention as a cap or beam results in freedom of space or freedom of movement when creating and setting up hewing and dismantling as well as in

It is also possible to create stamp-free route accompanying dams. Furthermore, the expansion profile according to the invention ensures an external link-free connection with expansion profiles to be connected at the end, so that a continuous running rail for load drives and consequently equipment and load transport is available. - This succeeds with relatively simple and functional means.
