Description
Bei der Herstellung eines nachgiebigen stählernen Streckenbogenausbaues aus Einzelstücken eines gleichflanschigen oder ungleichflanschigen I-Profils, aus Schienen od. dgl. ist es bekannt, als Verbindungslaschen Laschen zu verwenden, die aus zwei durch Schrauben miteinander verbundenen Hälften bestehen, deren Form der Segmentform angepaßt ist, und die als Seitenstützen für die Ausbausegmente dienen. In diese muffenartigen Gebilde werden die Segmentenden durch den Gebirgsdruck eingeschoben, wobei der Reibungsdruck zwischen der Lasche und den Segmentprofilen durch die die Laschenhälften miteinander verbindenden Schrauben reguliert werden kann.In the production of a flexible steel section arch extension from individual pieces of an I-profile with equal or unequal flanges Rails od. The like. It is known to use tabs as connecting tabs that consist of two halves connected to one another by screws, the shape of which is the Segment shape is adapted, and which serve as side supports for the expansion segments. The segment ends are pushed into these sleeve-like structures by the rock pressure, wherein the frictional pressure between the tab and the segment profiles through the The bolts connecting the bracket halves can be regulated.
Bei der Verwendung derartiger Verbindungslaschen als Stoßlasche des Bogenausbaues schlägt nun die vorliegende Erfindung vor, im unteren Teil der Lasche ein Füllstück fest :einzubringen, und zwar in Form eines Profilstückes, dessen Profil dein Profil der Ausbausegmente entspricht. Auf dieses Füllstück stützt sich das im oberen Teil der Lasche gleitende Ausbauprofilsegmentstück ab, sobald die gewollte Nachgiebigkeit des Ausbaurahmens erreicht ist. Dieses Füllstück, das gleichzeitig als, Fußstück dient Und mittels einer Schraube in der Lasche gehalten wird, kann zweckmäßig etwas über die Seitenstützen hinausragen rund: zur Erhöhung der Standsicherheit His Ausbaues beitragen.When using such connecting straps as the butt joint of the Arch expansion now proposes the present invention in the lower part of the flap a filler piece fixed: to be introduced, in the form of a profile piece, its profile your profile corresponds to the expansion segments. This is based on this filler piece in the upper part of the flap sliding expansion profile segment piece from as soon as the wanted one Resilience of the extension frame is achieved. This filler piece that at the same time serves as a foot piece and can be held in the bracket by means of a screw appropriately protrude slightly over the side supports: to increase stability Contribute to its expansion.
In. der Zeichnung ist der Erfindungsvorschlag in einem Ausführungsbeispiel in Verbindung mit einer an sich bekannten Lasche veranschaulicht, und zwar zeigt Abb. i einen offenen Streckenausbau finit starrer Seginentverbindung, Abb.2 einen solchen mit gelenkiger Segmentverbindung; Abb.3 zeigt die Seitenansicht der aus zweiteiligen zusammengeschraubten Laschen gebildeten Seitenstücken und Abb. q. eine Draufsicht hierauf; Abb. 5 zeigt die Queransicht in Pfeilrichtung B der Abb. 3, worin die Einspannung des I-förmigen Streckenprofils ersichtlich ist, und Abb.6 endlich zeigt einen Schnitt nach der Linie A- A der Abb. q. mit der Draufsicht auf das erfindungsgemäße Abstandfüllfußstück.In. the drawing illustrates the inventive proposal in an exemplary embodiment in connection with a bracket known per se, namely Fig. 1 shows an open stretch of finite rigid segment connection, Fig. 2 shows one with an articulated segment connection; Fig.3 shows the side view of the side pieces formed from two-part screwed tabs and Fig. Q. a plan view thereon; Fig. 5 shows the transverse view in the direction of arrow B of Fig. 3, in which the restraint of the I-shaped route profile can be seen, and finally Fig. 6 shows a section along the line A-A of Fig. Q. with the top view of the spacer filler foot according to the invention.
In den Abbildungen ist mit i das Seitensegment des offenen Streckenausbaues bezeichnet, und sind die aus, zwei Laschenhälften gebildeten Seitenstützen. Mit 3 ist die starre Segmentverbindung bezeichnet; q. ist die gelenkige Segmentverbindung, und 5 sind die Verbindungsschrauben der Seitenstützen. Das erfindungsgemäße Füllabstandfußstück am Ende der Seitenstütze ist mit 7 bezeichnet, und 6 sind kümpelförmige Aufpressungen im mittleren Stegteil der Laschen 2. Mit 8 ist der Bolzen bezeichnet, mittels dessen das Füllstück 7 mit der aus zwei Laschenhälften bestehenden Seitenstütze befestigt ist.In the figures, i is the side segment of the open route extension and are the side supports formed from two flap halves. With 3 denotes the rigid segment connection; q. is the articulated segment connection, and 5 are the connecting screws of the side supports. The filling spacer according to the invention at the end of the side support is indicated by 7, and 6 are dome-shaped pressings in the middle web part of the tabs 2. With 8 the bolt is referred to, by means of which the filler piece 7 is attached to the side support consisting of two flap halves is.
