Description

Die Erfindung betrifft ein Hilfsgeschirr zum Lösen einer Klemmverbindung für ineinander liegende Rinnenprofile des untertägigen Grubenausbaus gemäß den Merkmalen im Oberbegriff des Anspruchs 1.The invention relates to an auxiliary harness for releasing a clamping connection for nested channel profiles of the underground mine excavation according to the features in the preamble of claim 1.

Ein solches Hilfsgeschirr zählt im Umfang der DE 23 22 658 C zum der Technik. Es umfasst zwei aus Flacheisen bestehende Bügel, die mit bogenförmigen Haken hinter die Flansche des einliegenden Rinnenprofils greifen. Ferner weist das Hilfsgeschirr ein Widerlager auf, das von den Schenkeln der Bügel durchsetzt wird und sich mit einem Nocken am umfassenden Rinnenprofil abstützt. Der Fixierung des Hilfsgeschirrs an den Rinnenprofilen dient ein Keil, der durch Öffnungen in den Schenkeln der Bügel getrieben wird und auf diese Weise die Haken der Bügel und das Widerlager gegeneinander zieht.Such utensils count within the scope of DE 23 22 658 C to the technique. It comprises two brackets made of flat iron, which engage with curved hooks behind the flanges of the inset gutter profile. Furthermore, the utensils on an abutment, which is penetrated by the legs of the bracket and is supported with a cam on the comprehensive gutter profile. The fixation of the auxiliary harness to the channel profiles is a wedge, which is driven through openings in the legs of the bracket and in this way pulls the hooks of the bracket and the abutment against each other.

Ein weiteres Hilfsgeschirr ist in der DE 19 20 407 beschrieben. Hierbei weist ein Ausbau Ausbauelemente auf, welche sich teilweise überlappend gegeneinander verschieblich geführt sind und gleichzeitig durch Schlösser verspannt sind, wobei das Hilfsgeschirr aus einer die Ausbauelemente mit den Klammerenden vorgesehenen Einrichtungen zum Hinterfassen der Ausbauelemente und einer hydraulischen Zylinderkolbenanordnung im Bereich des Klammerrückens besteht. Hierbei ist vorgesehen, die Spannklammer aus einer Traverrse mit an beiden Enden angelenkten Klammerbügeln besteht.Another accessory is in the DE 19 20 407 described. In this case, an expansion on expansion elements, which are partially overlapping against each other slidably guided and simultaneously braced by locks, wherein the auxiliary harness from a the expansion elements provided with the clip ends means for grasping the expansion elements and a hydraulic Cylinder piston arrangement in the region of the clamp back exists. It is envisaged that the clamp consists of a Traverrse with hinged at both ends clamp brackets.

Darüber hinaus beschreibt die DE 30 19 314 C2 ebenfalls ein Hilfsvorrichtung für den Streckenausbau des Untertagebetriebes aus sich überlappenden mit Spannverbindungen zusammengehaltenen Ausbauprofilsegmenten, bestehend aus einem in der Überlappung ansetzbarem Geschirr und einer Spannvorrichtung, welche die Ausbauprofilsegmente zum Lösen der Spannvorrichtung verspannt und welche zum Lösen des Geschirrs aus der Ferne betätigbar ist. Dabei besteht das Geschirr aus einer Zange, deren einer Schenkel an einem Ende als Haken und am anderen Ende als Sitz für die Spannvorrichtung ausgebildet ist, wobei der andere Zangenschenkel zwischen dem Sitz und dem Haken angelenkt ist, und uf seiner Außenseite eine Kugelpfanne als Widerlager für das freie Ende einer Kolbenstange eines die Spannverbindung bildenden hydraulischen Zylinders aufweist.In addition, the describes DE 30 19 314 C2 also an auxiliary device for the track construction of the underground operation of overlapping with expansion joints held together Ausbauprofilsegmenten consisting of an attachable in the overlap harness and a tensioning device, which braces the Ausbauprofilsegmente to release the tensioning device and which can be operated for releasing the harness from a distance. The harness consists of a pair of pliers, one leg of which is formed as a hook at one end and as a seat for the tensioning device at the other end, wherein the other pliers leg is articulated between the seat and the hook, and uf its outside a ball socket as an abutment for Having the free end of a piston rod of the clamping connection forming hydraulic cylinder.

Problematisch an diesem Hilfsgeschirr ist zunächst der Keil, der keine auch sicherheitstechnische Aspekte im untertägigen Grubenbetrieb berücksichtigende einwandfreie Verspannung der beiden ineinander liegenden Rinnenprofile gewährleistet, um ein Wegschleudern der unter Spannung stehenden Klemmschrauben der die Rinnenprofile im Überlappungsbereich zusammen haltenden Klemmverbindungen zu verhindern.The problem with this auxiliary harness is first of all the wedge, which does not ensure any safety aspects in underground mine operation considering proper tension of the two nested channel profiles to prevent throwing away the tensioned clamping screws of the channel profiles in the overlap area together holding clamp connections.

Ferner muss im bekannten Fall hinter dem einliegenden und sich mindestens mittelbar am Gebirge abstützenden Rinnenprofil eine Freimachung an den beiden Flanschen geschaffen werden, damit die Haken der Bügel hinter den Flanschen angesetzt werden können.Furthermore, in the known case behind the inset and at least indirectly on the mountains supporting gutter profile a franking on the two flanges must be created so that the hooks of the bracket can be attached behind the flanges.

Darüberhinaus zählt ein mit hydraulischer Energie betätigbares Hilfsgeschirr zum Stand der Technik ( DE 2 254 993 C ). Abgesehen davon, dass auch bei diesem Hilfsgeschirr hinter den Flanschen des einliegenden Rinnenprofils Freimachungen zum Ansetzen der Haken der Bügel geschaffen werden müssen, besitzt ein solches auf hydraulischer Basis wirksames Hilfsgeschirr ein erhebliches Gewicht. Mit Rücksicht darauf, dass das Hilfsgeschirr von Hand an den Rinnenprofilen festgelegt werden uss, ist somit seine Akzeptanz seitens der Bergleute unter Tage gering, so dass die Verwendung häufig unterbleibt. Allerdings ist dann die Gefahr von Arbeitsunfällen im Hinblick auf brechende und dann weggeschleuderte Spannschrauben beim Lösen der Klemmverbindungen sehr hoch.Moreover, a hydraulically operated auxiliary equipment belongs to the prior art ( DE 2 254 993 C ). Apart from the fact that even with this utensils behind the flanges of the inset channel profile clearances for attaching the hooks of the bracket must be created, has such an effective hydraulic auxiliary equipment a considerable weight. Considering that the utensils are fixed by hand to the gutter profiles Thus, its acceptance by miners underground is low, so use often fails. However, then the risk of accidents at work with regard to breaking and then thrown clamping screws when loosening the clamp connections is very high.

Der Erfindung liegt - ausgehend vom Stand der Technik - die Aufgabe zugrunde, ein Hilfsgeschirr zum Lösen der Klemmverbindungen ineinander liegender Rinnenprofile des untertägigen Grubenausbaus zu schaffen, das vom Gewicht her von den Bergleuten akzeptiert wird und den untertägigen Sicherheitsaspekten in vollem Umfang genügt.The invention is - based on the prior art - the object of the invention to provide an auxiliary harness for releasing the clamping connections of each other lying gutter profiles of the underground mine expansion, which is accepted by the weight of the miners and the underground safety aspects fully complies.

Die Lösung dieser Aufgabe wird erfindungsgemäß in den Merkmalen des Anspruchs 1 gesehen.The solution to this problem is seen in the features of claim 1 according to the invention.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Grundgedankens sind Bestandteil der Ansprüche 2 bis 11.Advantageous developments of the basic concept according to the invention are part of claims 2 to 11.

Danach sind jetzt die Bügel des Hilfsgeschirrs U-förmig ausgebildet und liegen mit ihren Stegen zumindest mittelbar an einer das einliegende Rinnenprofil hintergreifenden Oberlasche einer Klemmverbindung. Das Widerlager ist von einer von den Schenkeln der Bügel relativ verlagerbar durchsetzten und an den Schenkeln fixierbaren Grundplatte sowie von einer sich an der das umfassende Rinnenprofil übergreifenden Unterlasche der Klemmverbindung abstützenden und in der Grundplatte drehbar gelagerten Spindel gebildet.Thereafter, now the stirrups of the utensils are U-shaped and lie with their webs at least indirectly on an engaging the gutter profile behind the upper flap of a clamping connection. The abutment is formed by one of the legs of the bracket relatively displaceable interspersed and fixable on the legs base plate as well as on the the comprehensive gutter profile cross tab of the clamping connection supporting and rotatably mounted in the base plate spindle formed.

Wichtig an der erfindungsgemäßen Gestaltung ist der Sachverhalt, dass nunmehr eine gesamte Klemmverbindung, bestehend aus Oberlasche, Unterlasche und Spannschrauben einschließlich Muttern in die Funktion des Hilfsgeschirrs einbezogen wird. Mit den Stegen hintergreifen die Bügel die über die Flansche des einliegenden Rinnenprofils seitlich vorstehenden hakenförmigen Abschnitte der Oberlasche, an denen sich auch die Köpfe der Spannschrauben abstützen. In diesem Zusammenhang ist es von besonderem Vorteil, dass die Stege auch die Köpfe der Spannschrauben übergreifen. Aufgrund der U-förmigen Gestaltung erstrecken sich die Schenkel der Bügel seitlich neben der Klemmverbindung und durchfassen Bohrungen in einer Grundplatte. Diese ist gegen ein Abgleiten von den Schenkeln mittels zwischen der Grundplatte und den freien Enden der Schenkel auf Gewindeabschnitte der Schenkel drehbaren Muttern sowie die Muttern und die Schenkel durchsetzende Splinte gesichert. Mittig der Grundplatte ist ein Spindel drehbar gelagert, die unter Abstützung an der Grundplatte bis zur Anlage an der das umfassende Rinnenprofil übergreifenden Unterlasche verdrehbar ist. Die Unterlasche fasst mit Wulsten in Hinterschneidungen der Flansche des umfassenden Rinnenprofils und besitzt Durchbrechungen für die Spannschrauben.Important to the design of the invention is the fact that now an entire clamping connection, consisting of top flap, bottom flap and clamping screws including nuts is included in the function of the auxiliary harness. With the webs, the brackets engage behind the hook-shaped portions of the upper flap laterally projecting beyond the flanges of the inset channel profile, against which the heads of the clamping screws are also supported. In this context, it is of particular advantage that the webs also overlap the heads of the clamping screws. Due to the U-shaped configuration, the legs of the bracket extend laterally next to the clamp connection and pass through holes in a base plate. This is against slipping from the Legs secured by means of between the base plate and the free ends of the legs on threaded portions of the legs rotatable nuts and the nuts and thighs passing through splints. In the middle of the base plate, a spindle is rotatably mounted, which is rotatable under support on the base plate until it abuts against the comprehensive bottom profile cross-bottom flap. The bottom flap holds with beads in undercuts of the flanges of the comprehensive gutter profile and has openings for the clamping screws.

Zum Ansetzen des Hilfsgeschirrs wird die Spindel zunächst so weit in der Grundplatte verdreht, bis dass die Stege der beiden Bügel problemlos über die seitlichen hakenförmigen Abschnitte der Oberlasche, bevorzugt auch hinter die Köpfe der Spannschrauben, verlagert werden können. Hierfür sind keine Freimachungen hinter den Flanschen des einliegenden Rinnenprofils notwendig, da die Abschnitte im Dickenbereich der Rinnenprofile liegen. Anschließend wird die Spindel gegen die Unterlasche bewegt. Nach ihrem Kontakt mit dem Steg der Unterlasche werden über die Spindel und die Grundplatte die Bügel fest gegen die Oberlasche gezogen, so dass dann eine sichere Verspannung der beiden ineinander liegenden Rinnenprofile gewährleistet ist. Der Einschubwiderstand der Rinnenprofile soll hierbei mindestens 150 kN betragen. Hierdurch wird sichergestellt, dass die Rinnenprofile nach dem Lösen der zwischen den Schenkeln der Bügel gut zugänglichen Muttern der Spannschrauben nicht relativ zueinander gleiten können.To attach the auxiliary harness, the spindle is first rotated so far in the base plate until the webs of the two straps can be easily moved over the side hook-shaped portions of the upper flap, preferably behind the heads of the clamping screws. For this purpose, no clearances are required behind the flanges of the incoming channel profile, since the sections are in the thickness range of the channel profiles. Subsequently, the spindle is moved against the lower flap. After their contact with the web of the lower flap over the spindle and the base plate, the straps are pulled firmly against the upper flap, so that then a secure clamping of the two nested channel profiles is guaranteed. The insertion resistance of the channel profiles should be at least 150 kN. This ensures that the channel profiles can not slide relative to each other after loosening the easily accessible between the legs of the bracket nuts of the clamping screws.

Das erfindungsgemäße Hilfsgeschirr kann vergleichsweise leicht gebaut werden, so dass seine Akzeptanz seitens der Bergleute hoch anzusetzen ist. Ferner ist seine Handhabung einfach. Es kann ohne weiteres von einem einzigen Bergmann angesetzt und auch wieder gelöst werden. Insbesondere diese beiden Sachverhalte dürften unter Einbeziehung der einwandfreien sicherheitstechnischen Funktion dazu beitragen, dass die Unfallgefahr deutlich reduziert werden kann.The auxiliary utensils according to the invention can be constructed comparatively easily, so that its acceptance by the miners is to be set high. Furthermore, its handling is easy. It can easily be started by a single miner and released again. In particular, these two circumstances, together with the impeccable safety-related function, should help to significantly reduce the risk of accidents.

Das Gewicht des Hilfsgeschirrs kann dadurch noch weiter reduziert werden, dass die Bügel aus Rundmaterial gebildet sind. Ihre Fertigung kann mit einfachen Biegeoperationen erfolgen.The weight of the auxiliary harness can be reduced even further, that the brackets are formed of round material. Their production can be done with simple bending operations.

Mittig der der Unterlasche gegenüberliegenden Stirnseite der Spindel ist vorteilhafter Weise ein Dorn vorgesehen. Dieser Dorn dringt beim Anlegen des Hilfsgeschirrs in das Material der Unterlasche ein und bewirkt eine Fixierung der Spindel an der Unterlasche. Hierdurch wird nicht nur ein Abrutschen der Spindel und damit des Hilfsgeschirrs von der Klemmverbindung verhindert, sondern darüber hinaus auch eine Markierung geschaffen, die es einer bergbehördlichen Kontrollinstanz erlaubt, einwandfrei nachzuvollziehen, ob beim Lösen der Klemmverbindungen der Rinnenprofile das erfindungsgemäße Hilfsgeschirr auch vorschriftsmäßig benutzt worden ist.In the middle of the bottom flap opposite end face of the spindle, a mandrel is advantageously provided. This mandrel penetrates when creating the auxiliary harness in the material of the lower flap and causes a fixation of the spindle on the lower flap. As a result, not only slipping of the spindle and thus of the auxiliary harness is prevented by the clamp connection, but also created a marker that allows a bergbehördlichen control instance to properly understand if the invention, the utensils according to the invention has also been used properly when loosening the clamp connections of the channel profiles ,

Herstellungstechnisch ist es günstig, wenn die Spindel in einer in der Grundplatte festgelegten Hülse drehbar gelagert ist. Zweckmäßig ist die Hülse mit einem umlaufenden Kragen versehen und in der Grundplatte ist eine entsprechende Stufenbohrung vorgesehen. Der Kragen ist den Rinnenprofilen zugewandt. Auf diese Weise wird ein Formschluss zwischen der Hülse und der Grundplatte erreicht, über welche die beim Verspannen des Hilfsgeschirrs auftretenden Kräfte einwandfrei abgefangen werden können. Auch erlaubt diese Gestaltung, dass die Hülse in die Grundplatte eingelötet werden kann und nicht eingeschweißt zu werden braucht.Manufacturing technology, it is advantageous if the spindle is rotatably mounted in a fixed in the base plate sleeve. Suitably, the sleeve is provided with a circumferential collar and in the base plate a corresponding stepped bore is provided. The collar faces the gutter profiles. In this way, a positive connection between the sleeve and the base plate is achieved, via which the forces occurring during bracing of the auxiliary harness can be properly intercepted. Also allows this design that the sleeve can be soldered into the base plate and does not need to be welded.

Um die Spindel einwandfrei drehen zu können, beispielsweise mittels eines Schlagschraubers, kann am freien Ende der Spindel ein Mehrkant vorgesehen sein.In order to rotate the spindle properly, for example by means of a striking screwdriver, a polygon can be provided at the free end of the spindle.

Zur Lagesicherung der Grundplatte an den Schenkeln der Bügel ist es vorteilhaft, dass die Grundplatte mittels Feststellmuttern an Gewindeabschnitten der Schenkel fixierbar ist. Diese befinden sich dann auf der den Splintmuttern gegenüber liegenden Seite der Grundplatte. Nach dem Anlegen des Hilfsgeschirrs an die Rinnenprofile kann auf diese Weise die Grundplatte an den Schenkeln der Bügel lagestabilisiert festgelegt werden.To secure the position of the base plate on the legs of the bracket, it is advantageous that the base plate can be fixed by means of locking nuts on threaded portions of the legs. These are then located on the side of the base plate opposite the split nuts. After applying the auxiliary harness to the channel profiles, the base plate can be fixed in position stabilized on the legs of the bracket in this way.

Zwecks Materialverringerung und damit einhergehender Gewichtsreduzierung sowie auch zum erleichterten Zugang, beispielsweise eines Schlagschraubers an die Muttern der Spannschrauben, ist die Grundplatte kreuzförmig konfiguriert, wobei von den Schenkeln der Bügel durchsetzte Bohrungen endseitig der sich strahlenförmig erstreckenden Plattenschenkel vorgesehen sind.For the purpose of material reduction and concomitant weight reduction as well as easier access, such as a wrench to the nuts of the clamping screws, the base plate is configured in a cross shape, which is provided by the legs of the bracket penetrated holes end of the radially extending plate legs.

Darüber hinaus ist es im Rahmen der Erfindung von Vorteil, dass die Schenkel der Bügel gekröpft sind. Die Kröpfung erfolgt in Richtung zur Spindel. Hierdurch werden die wirksamen Hebelarme von der Spindel zu den Ansatzbereichen der Stege der Bügel verringert, was dazu führt, dass weniger Momente eingeleitet werden. Ferner wird die Stabilisierung der Bügel bei der Montage verbessert. Die Abkröpfung dient auch dazu, dass Platz für einen Schlagschrauber geschaffen wird, um problemlos an die Muttern der Spannschrauben zu gelangen.Moreover, it is within the scope of the invention of advantage that the legs of the bracket are cranked. The cranking is done towards the spindle. As a result, the effective lever arms are reduced from the spindle to the neck portions of the webs of the bracket, resulting in that fewer moments are initiated. Furthermore, the stabilization of the bracket is improved during assembly. The bend also serves to make room for an impact wrench to easily access the nuts of the clamping screws.

Ein weiteres Merkmal der Erfindung besteht darin, dass mindestens zwei Schenkel der Bügel über eine Zugfeder verbunden sind. Die Zugfeder soll das Parallelhalten der beiden Bügel bei der Montage unterstützen. Sie sorgt mithin insbesondere dafür, dass bei der Montage des Hilfsgeschirrs die Stege der Bügel nicht von den hakenförmigen Abschnitten der Oberlasche beziehungsweise von den Köpfen der Spannschrauben abrutschen können. Sie liegt zweckmäßig im Längenbereich zwischen der Grundplatte und der den Dorn tragenden Stirnseite der Spindel.Another feature of the invention is that at least two legs of the bracket are connected via a tension spring. The tension spring is to support the parallel holding of the two brackets during assembly. In particular, it ensures that during the assembly of the auxiliary harness, the webs of the brackets can not slip off the hook-shaped portions of the upper flap or of the heads of the clamping screws. It is appropriate in the length range between the base plate and the end face of the mandrel carrying the mandrel.

Schließlich ist es noch von Vorteil, dass innenseitig der Stege der Bügel, und zwar neben den Schenkeln, Distanzstücke vorgesehen sind. Hierdurch wird der Kontur der Köpfe der Spannschrauben in Verbindung mit den seitlichen hakenförmigen Abschnitten der Oberlasche Rechnung getragen, so dass die Stege einwandfrei an den Köpfen der Spannschrauben sowie den hakenförmigen Abschnitten lageorientiert werden können.Finally, it is also advantageous that inside the webs of the bracket, in addition to the legs, spacers are provided. As a result, the contour of the heads of the clamping screws in conjunction with the lateral hook-shaped sections of the upper flap is taken into account, so that the webs can be properly positioned on the heads of the clamping screws and the hook-shaped sections.

Mit 1 ist in der Figur 1 der von zwei ineinander liegenden Rinnenprofilen 2,3 eines ansonsten nicht näher dargestellten untertägigen Grubenausbaus bezeichnet. Diese Rinnenprofile 2,3 setzen sich - wie auch die Figur 3 zeigt - jeweils aus einem Steg 4, an den Steg 4 sich anschließende, bogenförmig gekrümmte Schenkel 5 und endseitig der Schenkel 5 vorgesehenen Flanschen 6 zusammen. Die Flansche 6 sind hinterschnitten, so die Flansche 6 des umfassenden Rinnenprofils 2 sich den Hinterschneidungen 7 des einliegenden Rinnenprofils 3 formschlüssig können.With 1 is in the FIG. 1 of two intertwined gutter profiles 2.3 an otherwise not shown underground mining construction referred to. These channel profiles 2,3 sit down - as well as the FIG. 3 shows - each consisting of a web 4, the web 4 adjoining, arcuately curved legs 5 and the ends of the legs 5 provided flanges 6 together. The flanges 6 are undercut, so the flanges 6 of the comprehensive channel profile 2, the undercuts 7 of the inset channel profile 3 can form fit.

Im eingebauten Zustand werden die Rinnenprofile 2,3 im Überlappungsbereich 1 mittels mindestens zwei Klemmverbindungen 8 zusammengehalten, die sich (siehe Figuren 1, 3 und 4) jeweils aus einer das einliegende Rinnenprofil 3 hintergreifenden Oberlasche 9 mit seitlichen hakenförmigen Abschnitten 10, mit die Flansche 6 des einliegenden Rinnenprofils 3 übergreifenden Wulsten 11 und mit einem zwischen den Wulsten 11 vorgesehenen eingezogenen Längenabschnitt 12, einer das umfassende Rinnenprofil 2 übergreifenden Unterlasche 13 mit seitlich quer abstehenden Schenkeln 14 sowie mit in die Hinterschneidungen 7 der Flansche 6 des umfassenden Rinnenprofils 2 eingreifenden Wulsten 15 und aus Spannschrauben 16 mit Muttern 17 zusammensetzen. Die Spannschrauben 16 liegen mit ihren Köpfen 18 in den hakenförmigen Abschnitten 10 der Oberlasche 9, während die Muttern 17 sich an den seitlichen Schenkeln 14 der Unterlasche 13 abstützen.When installed, the channel profiles 2, 3 are held together in the overlapping area 1 by means of at least two clamping connections 8, which (see FIG FIGS. 1 . 3 and 4 ) in each case from one of the inset channel profile 3 engages behind upper flap 9 with lateral hook-shaped sections 10, with the flanges 6 of the incoming channel profile 3 cross beads 11 and provided between the beads 11 retracted length portion 12, a comprehensive gutter profile 2 cross-bottom flap 13 with laterally transversely projecting legs 14 and with engaging in the undercuts 7 of the flanges 6 of the comprehensive channel profile 2 beads 15 and clamping screws 16 with nuts 17 together. The clamping screws 16 are with their heads 18 in the hook-shaped portions 10 of the upper flap 9, while the nuts 17 are supported on the lateral legs 14 of the lower flap 13.

Um beim Rauben eines Grubenausbaus die Klemmverbindungen 8 sicher lösen zu können, wird ein aus den Figuren 2 bis 6 erkennbares Hilfsgeschirr 19 eingesetzt.To be able to solve the robbery of a pit removal, the clamp connections 8 safely, one of the FIGS. 2 to 6 recognizable auxiliary harness 19 used.

Das Hilfsgeschirr 19 weist zwei aus Rundstahl bestehende U-förmige Bügel 20 mit Stegen 21 und gekröpften Schenkeln 22 auf. Die Schenkel 22 besitzen endseitig Gewindeabschnitte 23, welche Bohrungen in sich strahlenförmig erstreckenden Schenkeln 24 einer kreuzförmig gestalteten Grundplatte 25 durchsetzen. Aufgrund der kreuzförmigen Ausbildung der Grundplatte 25 ergeben sich große umfangsseitige Aussparungen 26 und 27 (siehe insbesondere Figur 5), die zur Gewichtsreduzierung des Hilfsgeschirrs 19 beitragen. Außerdem dienen die Aussparungen 27 dem problemlosen Ansetzen zum Beispiel eines Schlagschraubers an die Muttern 17 der Spannschrauben 16.The auxiliary harness 19 has two round steel U-shaped bracket 20 with webs 21 and cranked legs 22. The legs 22 have end threaded portions 23 which pass through holes in radially extending legs 24 of a cross-shaped base plate 25. by virtue of the cross-shaped formation of the base plate 25 result in large circumferential recesses 26 and 27 (see in particular FIG. 5 ), which contribute to the weight reduction of the auxiliary harness 19. In addition, the recesses 27 are used for trouble-free attachment, for example, an impact wrench to the nuts 17 of the clamping screws sixteenth

Zur Lagesicherung der Grundplatte 25 an den 22 dienen Muttern 28, welche auf die Gewindeabschnitte 23 gedreht und mittels Splinte 29 gesichert werden.To secure the position of the base plate 25 to the nut 22 serve 28, which are rotated on the threaded portions 23 and secured by pins 29.

Innenseitig der Stege 21 der Bügel 20 befinden sich neben den Schenkeln 22 Distanzstücke 30, welche, wie insbesondere die Figur 4 erkennen lässt, den Konturen der Köpfe 18 der Spannschrauben 16 sowie der hakenförmigen Abschnitte 10 der Oberlasche 9 sind.On the inside of the webs 21 of the bracket 20 are located next to the legs 22 spacers 30, which, in particular the FIG. 4 can recognize the contours of the heads 18 of the clamping screws 16 and the hook-shaped portions 10 of the upper flap 9 are.

In der Grundplatte 25 ist mittig in Stufenbohrung 42 eine Hülse 31 festgelegt, beispielsweise eingelötet (Figur 6). Diese Hülse 31 besitzt ein Innengewinde 32 sowie einen Kragen 33, der dem umfassenden Rinnenprofil 2 zugewandt ist. Die Hülse 31 wird von einer Spindel 34 durchsetzt, die am freien Ende einen Mehrkant 35 zum Ansetzen eines Schlagschraubers und am gegenüberliegenden Ende einen Teller 36 aufweist. Mittig der Stirnseite 41 des Tellers 36 ist ein spitz auslaufender Dorn 37 vorgesehen,In the base plate 25, a sleeve 31 is centrally defined in stepped bore 42, for example, soldered ( FIG. 6 ). This sleeve 31 has an internal thread 32 and a collar 33 which faces the comprehensive channel profile 2. The sleeve 31 is penetrated by a spindle 34 having a polygon 35 at the free end for attaching a impact wrench and at the opposite end a plate 36. In the middle of the front side 41 of the plate 36, a pointed spout 37 is provided,

Außerdem lassen die Figuren 2 und 5 noch erkennen, dass zwei Schenkel 22 der Bügel 20 mittels einer Zugfeder 38 verbunden sind. Dadurch existiert eine Kraft, welche bestrebt ist, die Bügel 20 gegeneinander zu ziehen. Die Zugfeder 38 liegt zweckmäßig im Höhenbereich zwischen der Grundplatte 25 und der Unterlasche 13. Die Montage des Hilfsgeschirrs 19 wird auf diese Weise erheblich erleichtert.In addition, let the Figures 2 and 5 still recognize that two legs 22 of the bracket 20 are connected by a tension spring 38. As a result, there is a force which tends to pull the bracket 20 against each other. The tension spring 38 is appropriate in the height range between the base plate 25 and the bottom flap 13. The assembly of the auxiliary harness 19 is greatly facilitated in this way.

Zum Lösen der Klemmverbindungen 8 wird das Hilfsgeschirr 19 bei aus der Grundplatte 25 herausgedrehter Spindel 34 so im Bereich einer Klemmverbindung 8 angesetzt, dass die Bügel 20 mit den Stegen 21 einwandfrei über die hakenförmigen Abschnitte 10 der Oberlasche 9 und die Köpfe 18 der Spannschrauben 16 fassen. Das Hilfsgeschirr 19 hat dann die Konfiguration der Figuren 3 und 4. Danach werden Muttern 39 auf den Gewindeabschnitten 23, die auf der den vorausgehend erwähnten und mittels Sptinte 29 Muttern 28 gegenüberliegenden Seite der Grundplatte 25 liegen, in Richtung auf die Grundplatte 25 gedreht, so dass eine Lagefixierung der Grundplatte 25 an den Bügeln 20 gewährleistet ist. Danach wird die Spindel 34 gegen den Steg 40 der Unterlasche 13 verlagert (Figur 3), und zwar so weit, dass das Hilfsgeschirr 19 mit einer Kraft anliegt, die einen Einschubwiderstand der beiden Rinnenprofile 2,3 von mindestens 150 kN gewährleistet.To release the clamping connections 8, the auxiliary harness 19 is recognized in the screwed out of the base plate 25 spindle 34 in the region of a clamping connection 8 that the bracket 20 with the webs 21 perfectly on the hook-shaped portions 10 of the upper flap 9 and the heads 18 of the clamping screws 16 grasp , The auxiliary harness 19 then has the configuration of FIGS. 3 and 4 , After that will be Nuts 39 on the threaded portions 23, which are on the above-mentioned and by means of female 29 nuts 28 opposite side of the base plate 25, rotated in the direction of the base plate 25, so that a positional fixation of the base plate 25 is ensured on the brackets 20. Thereafter, the spindle 34 is displaced against the web 40 of the bottom flap 13 ( FIG. 3 ), and in fact so far that the auxiliary harness 19 is applied with a force that ensures a push-in resistance of the two channel profiles 2,3 of at least 150 kN.

Nach dem Anlegen des Hilfsgeschirrs 19 können die Klemmverbindungen 8 gefahrlos gelöst werden, so dass nach dem Entlasten des Hilfsgeschirrs 19 die Rinnenprofile 2,3 problemlos geraubt werden können.After the application of the auxiliary harness 19, the clamping connections 8 can be released safely, so that after relieving the auxiliary harness 19, the channel profiles 2.3 can be robbed easily.
