Description
Um das Ausbrechen der Ausbaubögen in einem eisernen Streckenausbau in Richtung der Streckenachse zu verhindern, hat man außer der üblichen Stahlverbolzung mittels Zugbolzen auch bereits eine kombinierte Zug- und Druckverbolzung gegen Schubkräfte angewendet, indem die Stahlbolzen beiderseitig an den Ausbaubögen festgelegt wurden. Hierbei kann man die Befestigungspunkte zweier benachbarter Bögen entweder durch horizontalliegende Bolzen miteinander verbinden, oder man verbindet zwei auf verschiedenen Horizontalen liegende Befestigungspunkte durch Diagonalbolzen, deren Richtung von Feld zu Feld dieselbe sein kann, so daß also alle Diagonalbolzen eines Ausbaufeldes parallel zueinander liegen, oder wechselt. Kombiniert man beide Arten der Bolzenverbindung, so erhält man einen Verband zwischen zwei Ausbaubögen, der allen Bewegungskräften in Richtung der Streckenachse standhält. Die Erfindung macht von diesen Verbänden eiserner Ausbaubögen im Ausbau von Strecken im stark druckhaften Gebirge Gebrauch. Ihr liegt die Erkenntnis zugrunde, daß es für gewisse Streckenabschnitte genügt, nur einen Teil der Ausbaubögen in einem solchen Verband zu vereinigen und die restlichen Bögen der Strecke an diesen Verband miteinander verankerter Streckenbögen durch ihre Zug- und Druckverbolzung anzuhängen. Demnach sind erfindungsgemäß von den eisernen Ausbauten eines Streckenabschnittes etwa ein Viertel oder weniger Ausbaubögen zusätzlich durch eine an sich bekannte Diagonalverbolzung zu einem Ankerverband zusammengefaßt, an den sich die zu beiden Seiten benachbarten Ausbaubögen gegen Schub- und Druck- wirkungen in Streckenrichtung verankern.In order to prevent the extension arches from breaking out in an iron track extension in the direction of the line axis, in addition to the usual steel bolting by means of tension bolts, a combined tension and compression bolting against shear forces has already been used by fixing the steel bolts on both sides of the extension arches. Here you can connect the fastening points of two adjacent arches either with horizontally lying bolts, or you can connect two fastening points lying on different horizontals with diagonal bolts, the direction of which can be the same from field to field, so that all diagonal bolts of an extension field are parallel to each other, or alternate . If you combine both types of bolt connections, you get a bond between two extension arches that can withstand all movement forces in the direction of the line axis. The invention makes use of these associations of iron expansion arches in the expansion of stretches in the heavily pressurized mountains. It is based on the knowledge that for certain sections of the route it is sufficient to combine only a part of the extension arches in such an association and to attach the remaining arches of the route to this association of anchored route arches by means of their tensile and pressure bolting. Accordingly, according to the invention, about a quarter or less of the extension arches of the iron extensions of a route section are additionally combined by a known diagonal bolting to form an anchor bond, on which the extension arches adjacent on both sides are attached to protect against shear and pressure. anchor effects in the direction of the route.
Das Ausbauverfahren gemäß der Erfindung bringt eine wesentliche Ersparnis von Ausbaumaterial und Zeit mit sich. Zur Befestigung der Diagonalbolzen dienen z. B. an ihren Kreuzungsstellen auf die Ausbaubögen aufgeschweißte Knotenbleche, an denen auch die Zugbolzen befestigt sind.The construction method according to the invention brings with it a substantial saving of construction material and time. To attach the diagonal bolts z. B. welded gusset plates at their crossing points on the expansion arches, to which the tie bolts are also attached.
In der Zeichnung ist ein Ankerverband von fünf nebeneinanderliegenden Streckenbögen in der Ansicht dargestellt. Die horizontalliegenden Zug- und Druckbolzen 1 teilen die Fläche zwischen zwei benachbarten Bögen in Felder. Die Diagonalbolzen 2 wechseln ihre Richtung von Feld zu Feld sowohl beim Fortschreiten in Richtung der Streckenachse wie auch senkrecht dazu. Auf diese Weise entstehen rautenförmige Gitter. In den Kreuzungspunkten sind einseitig bzw. beiderseitig an die Ausbaubögen Knotenbleche 3 angeschweißt, an denen außer den Diagonalbolzen auch die horizontalliegenden Zugbolzen befestigt sind.In the drawing, an anchor connection of five adjacent line arcs is shown in the view. The horizontal tension and compression bolts 1 divide the area between two adjacent arches into fields. The diagonal bolts 2 change their direction from field to field both when advancing in the direction of the line axis and perpendicular to it. In this way, diamond-shaped grids are created. At the crossing points, gusset plates 3 are welded on one side or on both sides of the expansion arches, to which, in addition to the diagonal bolts, the horizontally lying tension bolts are also attached.
