Description
VERBOLZUNG FÜR AUSBAURAHMEN AUS RINNENPROFIL Die Erfindung betrifft eine Verbolzung für Ausbaurahmen aus Rinnenprofil, welche Abstandbolzen aus Winkeleisen aufweist, die mit Ausnehmungen zum Vbergreifen der Flansche der Rinnenprofile versehen sind und welche mittels Spanngliedern an den Rinnenprofilen befestigbar sind.BOLTING FOR SUPPORTING FRAMES FROM GUTTER PROFILE The invention relates to a bolting for extension frame made of channel profile, which spacer bolts made of angle iron has, which are provided with recesses for engaging the flanges of the channel profiles and which can be attached to the channel profiles by means of tendons.
Es ist eine Stoßverbolzung für Rinnenprofile bekannt geworden, bei welchen die Abstandbolzen über benachbarte Baue gelegt sind und für jeden Flansch in einem Schenkel der aus Winkeleisen bestehenden Abstandbolzen Ausnehmungen vorgesehen sind.A butt bolting for channel profiles has become known at which the spacer bolts are placed over adjacent structures and for each flange Recesses provided in one leg of the spacer bolts made of angle iron are.
Die Verspannung mit den Ausbaurahmen geschieht mit Hilfe von Haltebügeln, welche mit Abbiegungen in Bohrungen des senkrechten Schenkels des Abstandbolzens befestigt sind und das ganze Profil unterfassen, wobei die eigentliche Verspannwirkung mittels sich an den Profilen abstützenden Keilen bewirkt wird.The bracing with the extension frame is done with the help of retaining brackets, which with bends in holes of the vertical Leg of Spacer bolts are attached and grasp the whole profile, with the actual Bracing effect is effected by means of wedges supported on the profiles.
Diese bekannte Verbolzung weist den Nachteil auf, daß die Abstandbolzen durchgehend angeordnet sind, d.h. jedes Profil zweimal überbaut werden muß, was einen vergleichsweise großen Aufwand darstellt.This known bolting has the disadvantage that the spacer bolts are arranged continuously, i.e. each profile has to be built over twice, which represents a comparatively large effort.
Von diesem Stand der technik ausgehend liegt der Erfindung die Aufgabe zugrunde, unter Vermeidung vorerwähnter Nachteile eine Verbolzung der eingangs genannten Art zu schaffen, welche in einfacher Weise herzustellen und zu montieren ist und im übrigen den von den Bergbehörden vorgeschriebenen Anforderungen in vollem Umfange gerecht wird.Based on this prior art, the invention is based on the task based on, while avoiding the disadvantages mentioned above, a bolting of the aforementioned Type of creation which is easy to manufacture and assemble and otherwise fully complies with the requirements stipulated by the mining authorities is fair.
Gemäß der Erfindung wird dies dadurch erreicht, daß als Spannglieder Winkelstücke dienen, die in ihren senkrechten Schenkeln stirnseitig Ausnehmungen besitzen und in ihren waagerechten Schenkeln mit Durchtrittsbohrungen für Schraubbolzen ausgerüstet sind, welche mit Durchtrittsbohrungen in den waagerechten Schenkeln der Abstandbolzen fluchten, wobei die Winkelstücke mit den Enden der Abstandbolzen kastenförmig zusammengefügt sind.According to the invention this is achieved in that as tendons Elbows are used, the front side recesses in their vertical legs own and in their horizontal legs with through-holes for screw bolts are equipped with through-holes in the horizontal legs the spacer bolts are aligned, the angle pieces with the ends of the spacer bolts are joined together in a box shape.
Die Abstandbolzen verlaufen nicht mehr über die Awbaurahmen hinweg, sondern überragen die Flanschen nur geringfügig, so daß eine insgesamt fluchtende Anordnung der Verbolzung möglich ist.The spacer bolts no longer run over the building frame, but protrude only slightly beyond the flanges, so that a total of aligned Arrangement of the bolting is possible.
Außerdem sind die Befestigungsmittel einfache Stanzteile, die sehr leicht hergestellt und insbesondere auch montiert werden können.In addition, the fasteners are simple stampings that are very can be easily manufactured and, in particular, also assembled.
Ein Ausführungsbeispiel der Erfindung ist an Hand der Zeichnung näher erläutert, und zwar zeigt: Fig. 1 die teilweise geschnittene Ansicht eines Ausbaurahmens mit den beiden Enden der an diesem befestigten Abstandbolzen und Fig. 2 eine geschnittene Seitenansicht gemäß dr Linie II - II der Fig. 1.An embodiment of the invention is shown in more detail with reference to the drawing explained, namely shows: Fig. 1 is a partially sectioned view of a support frame with the two ends of the spacer bolts attached to this and FIG. 2 is a section Side view according to line II - II of FIG. 1.
Mit 1 ist der. Ausbaurahmen aus Rinnenprofil bezeichnet, welcher mittels der Abstandbolzen 2,3 aus Winkeleisen an die benachbarten, nicht weiter dargestellten Ausbaurahmen angeschlossen ist, d.h. mit diesen verbolzt ist. Die senkrechten Schenkel 4 der Abstandbolzen 2,3 sind mit Ausnehmungen 5 versehen, welche die Flansche 6 der Ausbaurahmen 1 übergreifen.With 1 is the. Extension frame from channel profile referred to, which by means of the spacer bolts 2.3 made of angle iron to the neighboring, not shown Extension frame is connected, i.e. is bolted to it. The vertical legs 4 of the spacer bolts 2, 3 are provided with recesses 5, which the flanges 6 the expansion frame 1 overlap.
An den Enden der Bolzen 2,3 sind die Winkelstücke 7 befestigt, und zwar mittels der Schraubbolzen 8, die miteinander fluchtende Durchtrittsbohrungen 9, 10 in den waagerechten Schenkeln 11, 12 der Abstandbolzen 2,3 und der Winkelstücke 7 durchsetzen.At the ends of the bolts 2,3 the angle pieces 7 are attached, and although by means of the screw bolts 8, the aligned through holes 9, 10 in the horizontal legs 11, 12 of the spacer bolts 2,3 and the angle pieces 7 enforce.
Wie insbesondere Fig. 2 erkennen läßt, sind die Enden der Abstandbolsen 2,3 und die diesen zugeordneten Winkelstücke 7 kastenförmig zusammengefügt, so daß sich ein außerordentlich steifer Verbund ergibt.As can be seen in particular from FIG. 2, the ends of the spacer bolts are 2, 3 and the elbows 7 assigned to them are box-shaped put together, so that an extremely stiff composite results.
Fig. 1 läßt erkennen, daß die Winkelstücke 7 an den Stirnseiten ihrer senkrechten Schenkel 13 Ausnehmungen 14 besitzen, welche die Flansche 6 der Ausbaurahmen 1 untergreifen, so daß diese im Zusammenwirken mit den Ausnehmungen 5 der Abstandbolzen 2,3 sicher eingespannt sind.Fig. 1 shows that the elbows 7 on the end faces of their vertical legs 13 have recesses 14, which the flanges 6 of the support frame 1 reach under, so that this interacts with the recesses 5 of the spacer bolts 2.3 are securely clamped.
