Definitions
- the invention relates to a roadway structure according to the preamble of claim 1.
- the curb serves to limit a road surface and has the function of making it difficult or impossible to drive on an area adjacent to the roadway for vehicles.
- the curbs are subject to only occasional loads and are usually run over at low speed.
- the curbs have the function of delimiting two lanes from each other and to bridge a small difference in level between the lanes. This level difference is desired to make it clear to the driver of a vehicle that a driving surface is leaving.
- the object of the invention is to develop a roadway structure in which the curb keeps better the traffic loads.
- the invention provides to integrate in the roadway a curb, which is arranged at least 90% of its height below the lower road surface and in to arrange at least one recess in its lower region.
- the invention further provides to form the recess on the underside of the curb as a groove extending in a longitudinal direction.
- a return is easy to implement manufacturing technology, causes the desired enlargement of the contact surface to the foundation and facilitates the formation of two ridges pressing the curb into the fresh foundation or causes a full-surface contact between the foundation and curb, since the foundation forming concrete less is forced to flow horizontally to enclose the curb.
- An advantageous embodiment of the invention provides to realize the recess in the region of the side surface as a chamfer, which terminates in the underside of the curb.
- the recesses are formed at least partially mirror-symmetrically to the longitudinal direction of the curb. As a result, a uniform Einink the curb is achieved in the fresh foundation.
- An expedient embodiment of the subject invention provides to keep the curb in a foundation which is T-shaped or L-shaped and preferably extends at least two curbs below or in the foundation of the road surface.
- a foundation serves as a tilt protection for the boron stone, which is able to distribute forces and torques acting on the curb over a large area onto the ground or to pass them on to the foundations of the road surface.
- a curb which is trapezoidal in plan view and whose side surfaces, which are opposite curbs, have a miter.
- a wedge-like design in plan view makes it possible to realize narrow gaps between the contact surfaces of the curbs in curb-laid curb rows.
- a polygon-like curb line stabilizes itself against acting on the wider front or the top loads by wedging itself. Due to the small gap dimensions is sufficient for the mutual wedging a minimal shift.
- FIG. 1 is a plan view of a section of a roundabout 1 shown.
- the roundabout 1 consists of an island 2, which is not intended for driving on vehicles.
- the island 2 is surrounded by a first running surface 3 annular.
- the first running surface 3 is enclosed by a ring 4 of curbs 5, which merges into an annular second running surface 6.
- the curb 5 has in a head region 7 on an upper side 8, which is formed by a flat surface 9 and an inclined surface 10.
- the flat surface 9 lies with the first running surface 3 in a common plane E.
- the inclined surface 10 drops to a plane F, which is formed by the second running surface 6.
- the first running surface 3 is formed as a paving surface 11, which consists of individual in FIG. 1 Not constructed paving stones is constructed.
- the first running surface 3, the ring 4 of curbs 5 and the second running surface 6 together form a lane 12 intended for traffic.
- the first running surface 3 and the ring 4 of curbs 5 are preferred by vehicles which due to their speed by the Ride 6 predetermined turning radius can not comply, and of large vehicles for which the second running surface 6 is too narrow, drove over or over.
- This act when driving on a formed from the first driving surface 6 and the ring 4 curbs 5 special driving surface 13 forces from arrow directions b 1 , b 2 , b 3 , b 4 on the curbs. These forces are introduced by the vehicle tires mainly in the area of the inclined surface 10 of the upper side 8 of the curb 5.
- FIG. 2 shows a plan view of a section of running as a straight road traffic area 14.
- This consists in analogy to in FIG. 1 illustrated roundabout from a first running surface 3, which passes over a row 15 of curbs 5 in a second driving surface 6.
- the second running surface 6 lies in a plane F, which is lower than a plane E, which is formed by the first running surface 3 and flat surfaces 9 of tops 8 of the curbs 5.
- the smooth transition between these planes E, F is ensured by an inclined surface 10 on the tops 8 of the curbs 5, which lie together in an inclined plane G.
- forces from approximately one direction b5 act on the curbs 5.
- the direction from which the forces act on the curbs 5 when approaching is in detail dependent on the angle at which the respective vehicle ascends. In general, however, at the roundabout and at the straight road, the attacking forces should be assumed at a point angle.
- FIG. 3 shows a perspective view of a curb 5.
- the curb 5 has an upper surface 8, which is formed by a flat surface 9 and an inclined surface 10.
- the curb 5 is laterally delimited by a front side 16, a rear side 17, a right side 18 and a left side 19.
- the top 8 is opposite an underside 20.
- With a head portion 7 of the curb 5 is oriented to the road and with a foot portion 21 of the curb 5 in the staggered state in a foundation (see FIGS. 7 . 8th ) embedded.
- the curb 5 recesses 22, which are formed as recesses against an imaginary cuboid foot area.
- One of the recesses 22 is formed on the underside 20 as a groove 23 and extends in a longitudinal direction x.
- the groove 23 causes a positive connection between the curb 5 and the foundation, not shown, so that in particular about a side wall 24 of the groove 23 about a direction y on the curb 5 acting forces can be transmitted to the foundation. For example, from a direction b 5 forces acting on the curb 5 can be transmitted via the side wall 24 at least partially on the foundation.
- the recesses 22 are realized, which are formed as chamfers 25. These run in the direction of the groove 23 and make the curb in the foot 21 slender.
- the chamfers 25 are in other words formed by chamfers on edges 26, 27 between the front 16 and the bottom 20 and between the back 17 and the bottom 20.
- the slender and wedge-like design of the side of the groove 23 formed webs 28, 29 is also effected by recesses 22, resulting from the breaking of imaginary corners of the bottom 20. This makes it possible that in the area of the broken corners concrete of the foundation between strung curbs 5 penetrates and embeds the curbs 5 tooth-like in the foundation. This type of embedding allows a stronger load of curbs.
- FIG. 4 is a view of the top 8 of the curb 5 shown.
- the curb 5 has a width B 5 of about 50 cm and a depth T 5 of about 30 cm.

- FIG. 6 is a view of the right side 18 of the curb 5 shown.
- the groove 23 has a height H 23 of about 1.5 cm and a width B 23 of about 10 cm.
- the sloping surface 10 of the upper side 8 of the curb 5 bridges a height H 10 of about 3.5 cm.
- the edge between the top 8 and the back 17 is provided with a chamfer.
- the curb 5 has at the height H 5 of about 35 to 40 cm an embedding depth H E of about 31.5 to 36 cm. According to an embodiment variant, not shown, it is provided to produce the curb with a depth T 5 of about 20cm and to reduce the width of the groove B 23 to about 5 cm.

Description
Die Erfindung betrifft einen Fahrbahnaufbau gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a roadway structure according to the preamble of
Aus dem Stand der Technik sind eine Vielzahl von Fahrbahnaufbauten mit Bordsteinen bekannt, siehe zum Beispiel

Aus der
Aufgabe der Erfindung ist es, einen Fahrbahnaufbau zu entwickeln, bei welchem der Bordstein den Verkehrsbelastungen besser Stand hält.The object of the invention is to develop a roadway structure in which the curb keeps better the traffic loads.
Diese Aufgabe wird ausgehend von den Merkmalen des Oberbegriffs des Anspruchs 1 durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Durch die in den Unteransprüchen genannten Merkmale sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich.This object is achieved on the basis of the features of the preamble of
Die Erfindung sieht vor, in die Fahrbahn einen Bordstein zu integrieren, welcher mit wenigstens 90% seiner Höhe unterhalb des tiefer liegenden Fahrbahnbelags angeordnet ist und in seinem unteren Bereich wenigstens eine Ausnehmung anzuordnen. Durch eine solche vorhältnismäßig tiefe Einbettung des Bordsteins in die Fahrbahn können insbesondere die beim Überfahren auf den Bordsteins erzeugten Momente gut in das Fundament eingeleitet werden, da bei einem in einem der Fahrfläche nahen Bereich liegenden Drehpunkt im Fußbereich des Bordsteins auf grund des großen Hebels nur relativ geringe Gegenkräfte zwischen Fundament und Bordstein übertragen werden müssen. Die Möglichkeit Kräfte und Momente aufzunehmen wird durch die Ausnehmungen noch vergrößert, da durch diese zusätzliche Anlageflächen geschaffen werden, über welche die einwirkenden Kräfte und Momente in das Fundament weitergeleitet werden können. Insgesamt bewirken diese Maßnahmen eine Herabsetzung der Belastungsspitzen zwischen Bordstein und Fundament, da sich die Kräfte auf größere Flächen verteilen und erhöhen somit die Lebensdauer des Bordsteins.The invention provides to integrate in the roadway a curb, which is arranged at least 90% of its height below the lower road surface and in to arrange at least one recess in its lower region. By such a disproportionately deep embedding of the curb in the roadway, in particular the moments generated when driving over the curb can be well introduced into the foundation, since at a near in the driving area near the pivot point in the foot of the curb due to the large lever only relatively low opposing forces between foundation and curb must be transmitted. The ability to absorb forces and moments is further increased by the recesses, as are created by this additional contact surfaces over which the acting forces and moments can be passed in the foundation. Overall, these cause Measures a reduction of the load peaks between curb and foundation, as the forces spread over larger areas and thus increase the life of the curb.
Die Erfindung sieht weiterhin vor, den Rücksprung an der Unterseite des Bordsteins als eine in eine Längsrichtung verlaufende Nut auszubilden. Ein solcher Rücksprung ist fertigungstechnisch einfach zu realisieren, bewirkt die gewünschte Vergrößerung der Anlagefläche zum Fundament und erleichtert durch die Ausbildung von zwei Rücken das Eindrücken des Bordsteins in das frische Fundament bzw. bewirkt einen vollflächigen Kontakt zwischen Fundament und Bordstein, da der das Fundament bildende Beton weniger gezwungen ist waagrecht zu fließen, um den Bordstein zu umschließen.The invention further provides to form the recess on the underside of the curb as a groove extending in a longitudinal direction. Such a return is easy to implement manufacturing technology, causes the desired enlargement of the contact surface to the foundation and facilitates the formation of two ridges pressing the curb into the fresh foundation or causes a full-surface contact between the foundation and curb, since the foundation forming concrete less is forced to flow horizontally to enclose the curb.
Eine vorteilhafte Ausbildung der Erfindung sieht vor, die Ausnehmung im Bereich der Seitenfläche als Abschrägung zu verwirklichen, welche in der Unterseite des Bordsteins ausläuft. Durch eine derartige Formgebung ist das Einsetzen des Bordsteins in das frische Fundament weiter erleichtert, da der Bordstein durch diese Fase zum Fundament hin keilähnlich ausgebildet ist.An advantageous embodiment of the invention provides to realize the recess in the region of the side surface as a chamfer, which terminates in the underside of the curb. By such a shape, the insertion of the curb in the fresh foundation is further facilitated, since the curb is formed wedge-like by this chamfer to the foundation.
Weiterhin ist es vorgesehen, die Ausnehmung im Bereich dreier aufeinandertreffender Seitenflächen auszubilden. Hierdurch entsteht ebenfalls eine keilartige Ausbildung des Fußbereichs des Bordsteins mit den oben genannten Vorteilen.Furthermore, it is provided to form the recess in the region of three juxtaposed side surfaces. This also creates a wedge-like design of the foot of the curb with the advantages mentioned above.
Es ist von besonderem Vorteil, wenn die Ausnehmungen wenigstens teilweise spiegelsymmetrisch zur Längsrichtung des Bordsteins ausgebildet sind. Hierdurch wird ein gleichmäßiges Einsinkverhalten des Bordsteins in das frische Fundament erreicht.It is of particular advantage if the recesses are formed at least partially mirror-symmetrically to the longitudinal direction of the curb. As a result, a uniform Eininkverhalten the curb is achieved in the fresh foundation.
Eine zweckmäßige Ausgestaltung des Erfindungsgegenstandes sieht vor, den Bordstein in einem Fundament zu halten, welches T-förmig oder L-förmig ausgebildet ist und vorzugsweise um wenigstens zwei Bordsteinbreiten unter oder in das Fundament der Fahrbahnbeläge reicht. Ein derartiges Fundament dient als Kippsicherung für den Borstein, welche in der Lage ist auf den Bordstein wirkende Kräfte und Momente großflächig auf den Untergrund zu verteilen bzw. in die Fundamente der Fahrbahnbeläge weiterzuleiten.An expedient embodiment of the subject invention provides to keep the curb in a foundation which is T-shaped or L-shaped and preferably extends at least two curbs below or in the foundation of the road surface. Such a foundation serves as a tilt protection for the boron stone, which is able to distribute forces and torques acting on the curb over a large area onto the ground or to pass them on to the foundations of the road surface.
Insbesondere für den Fahrbahnaufbau eines Kreisverkehrs ist ein Bordstein geeignet, welcher in Draufsicht trapezförmig ausgebildet ist bzw. dessen Seitenflächen, welche benachbarten Bordsteinen gegenüberliegen, eine Gehrung aufweisen. Durch eine derartige in Draufsicht keilartige Ausbildung ist es möglich bei bogenförmig verlegten Bordsteinreihen enge Spalte zwischen den Kontaktflächen der Bordsteine zu verwirklichen. Weiterhin stabilisiert sich eine polygonartig verlegte Bordsteinreihe gegen auf die breitere Vorderseite bzw. die Oberseite wirkende Belastungen durch Verkeilen selbst. Durch die geringen Spaltmaße reicht für das gegenseitige Verkeilen eine minimale Verschiebung aus.In particular, for the roadway construction of a roundabout a curb is suitable, which is trapezoidal in plan view and whose side surfaces, which are opposite curbs, have a miter. Such a wedge-like design in plan view makes it possible to realize narrow gaps between the contact surfaces of the curbs in curb-laid curb rows. Furthermore, a polygon-like curb line stabilizes itself against acting on the wider front or the top loads by wedging itself. Due to the small gap dimensions is sufficient for the mutual wedging a minimal shift.
