Description

Leiteinrichtung an Fahrbahnen Die Erfindung betrifft eine Leiteinrichtung an Fahrbahnen.Guide device on roadways The invention relates to a guide device on roadways.

Bekannt sind Leiteinrichtungen en Fahrbahnen mit quer zur Fahrbahn schwenkbaren und federnd abgestützten Pfosten mit daran quer zur Fahrbahn federnd abgestützten Leitplanken, wobei die Federkonstante der den Pfosten stützenden Feder größer ist als die der die Leitplanke stützenden Feder. Diese bekannten Leiteinrichtungen sind jedoch recht verwickelt im Aufbau und daher störanfällig und teuer.Control devices are known in lanes with transverse to the lane pivotable and resiliently supported post with resilient on it transversely to the roadway supported crash barriers, the spring rate of the spring supporting the post is larger than that of the spring supporting the guardrail. These known guiding devices however, they are very complex and therefore prone to failure and expensive.

Die Erfindung vermeidet diese Nachteile und besteht darin, daß bei Leiteinrichtungen der genannten Art die Pfosten gegen das freie Ende einer am Pfostensockel befestigten Blattfeder abgestützt sind. Besonders zu empfehlen ist, daß die Blattfeder, im Längsschnitt betrachtet, in ihrem mittleren Bereich viertelkreisförmig gebogen ist und der Pfosten unter Wirkung der Blattfeder gegen einen fahrbahnseitig des Gelenkbolzens des Pfostens gelegenen Anschlag in der Normalstellung anliegt.The invention avoids these disadvantages and consists in that at Guiding devices of the type mentioned, the posts against the free end of one on the post base attached leaf spring are supported. It is particularly recommended that the leaf spring, viewed in longitudinal section, curved in the middle of a quarter circle is and the post under the action of the leaf spring against a road side of the Joint bolt of the post located stop in the normal position.

Die Zeichnung gibt eine Leiteinrichtung nach der Erfindung beispielsweise wieder, und zwar zeigt Fig.l einen senkrechten Längsschnitt quer zur Fahrbahn, Fig. 2 eine Rückansicht und Fig. 3 die Leiteinrichtung nach der Erfindung in der Draufsicht.The drawing gives a guide device according to the invention, for example again, namely Fig.l shows a vertical longitudinal section transversely to the roadway, Fig. 2 shows a rear view and FIG. 3 shows the guide device according to the invention in plan view.

Haltebänder 1 und 2, die von einer Betonschicht 3 umgeben sind, ragen aus dem Erdboden 4 heraus und sind außen an ein etwa waagerecht liegendes Profileisen 5 von doppel-T-förmigem Querschnitt angeschweißt. Haltebänder 1 und 2 und das Profileisen 5 bilden zusammen den Pfostensockel 6.Retaining straps 1 and 2, which are surrounded by a concrete layer 3, protrude out of the ground 4 and are on the outside of an approximately horizontally lying profile iron 5 welded on by a double-T-shaped cross-section. Retaining straps 1 and 2 and the profile iron 5 together form the post base 6.

Mit dem oberen Ende der Haltebänder 1, 2 ist drehbar ein Pfosten 7 durch einen Bolzen 8 verbunden, dessen Lage durch Sprengstifte 9, 10 gesichert ist. Am einen Ende des Profileisens 5 ist ein Winkelstück 11 angeschweißt, welches zur Abstützung der im mittleren Bereich viertelkreisförmig gebogenen Blattfedern 12,13 dient. Eine Schraube 14 geht durch Bohrungen der Blattfedern 12, 13 hindurch und hat die Aufgabe, die Federn mehr oder weniger stark gegen die Innenseite 15 der Vorderwand des Pfostens 7 zu drücken, bis dieser gegen den Anschlag 16 am Quersteg 17 des Profileisens 5 anliegt.A post 7 is rotatable with the upper end of the retaining straps 1, 2 connected by a bolt 8, the position of which is secured by snap pins 9, 10. At one end of the profile iron 5, an elbow 11 is welded, which for Support of the leaf springs 12, 13, which are bent in a quarter circle in the middle area serves. A screw 14 goes through holes in the leaf springs 12, 13 and has the task of the springs more or less strongly against the inside 15 of the To press the front wall of the post 7 until it hits the stop 16 on the crosspiece 17 of the profile iron 5 is applied.

Am oberen Ende des Pfostens 7 ist ein etwa waagerecht liegendes Rohr 18 vorgesehen, welches eine Stange 19 führt. Die Stange 19 trägt an der Außenseite eine Scheibe 20, die durch eine Maschinenschraube 21 gehalten ist und am äußeren Ende des Rohres 18 anliegt. Am freien Ende der Stange 19 ist ein Bügel 22 angeschweißt, an welchem die Leitplanke 23 mittels Schrauben 24 und 25 befestigt ist.At the upper end of the post 7 is an approximately horizontally lying pipe 18 is provided, which a rod 19 guides. The rod 19 carries on the outside a washer 20 which is held by a machine screw 21 and on the outer End of the tube 18 is applied. A bracket 22 is welded to the free end of the rod 19, to which the guardrail 23 is attached by means of screws 24 and 25.

über die Stange 19 ist eine Schraubenfeder 26 geschoben, die mit ihrem einen Ende an dem Bügel 22, mit ihrem anderen Ende an einer Ansatzfläche 27 einer Hülse 28 anliegt, welche die gleiche Achse hat wie das Rohr 18 und ebenfalls mit dem Pfosten 7 fest verbunden ist.A coil spring 26 is pushed over the rod 19, which with her one end on the bracket 22, with its other end on an attachment surface 27 one Sleeve 28 is applied, which has the same axis as the tube 18 and also with the post 7 is firmly connected.

Für jede Leitplanke 23 sind mindestens zwei Pfosten 7 mit allen den oben beschriebenen Zusatzteilen vorgesehen.For each guardrail 23 are at least two posts 7 with all the Additional parts described above are provided.

Wird die Leitplanke 23 von einem vorbeifahrenden Kraftwagen nur leicht gestreift, so schiebt sich lediglich die Stange 19 entgegen dem Druck der Schraubenfeder 26 nach außen, während die Blattfedern 12, 13 diesen leichten Druck ohne jede Formveränderung aushalten. Bei starkem Anprall aber lindert die Schraubenfeder 26 lediglich den ersten Stoß, während die dem Kraftwagen innewohnende kinetische Energie von den sich zurückbiegenden Blattfedern 12, 13 aufgenommen und zum großen Teil durch die Reibung der Blattfedern gegeneinander oder gegenüber der Innenwandung 15 des Pfostens 7 verbraucht wird.If the guardrail 23 is only slightly from a passing motor vehicle striped, only the rod 19 pushes against the pressure of the helical spring 26 to the outside, while the leaf springs 12, 13 this slight pressure without any change in shape endure. In the event of a severe impact, however, the helical spring 26 only alleviates the first impact, while the kinetic energy inherent in the motor vehicle is derived from the bending back leaf springs 12, 13 added and for the most part by the Friction of the leaf springs against each other or against the inner wall 15 of the post 7 is consumed.
