Definitions
- the invention relates to a roadway structure according to the Preamble of claim 1.
- Such arrangements can be found, for example, in Transition area from a driveway to a traffic lane or at roundabouts. These are an inner circle often paved. At roundabouts with low Diameters are heavy, large vehicles regularly forced to dodge on the paved circular ring to to be able to drive through the roundabout at all. All in all can be found that driving over such curbs used a high burden of curbs or the roadway structure in the area of curbs causes because the crossing speeds are independent of Vehicle weight are high. As a result of these burdens often after a relatively short time a loosening of curbs and often a shift in the direction of travel detected.
- the object of the invention is to a roadway construction develop at which curb the traffic loads holds better.
- the invention provides for a curb in the roadway integrate which with at least 90% of its height below of the lower road surface is arranged and in to arrange at least one recess in its lower region.
- the invention further provides, the return to the Bottom of the curb as one in a longitudinal direction form running groove.
- a return is production technology easy to implement, causes the desired enlargement of the contact surface to the foundation and relieved by the training of two backs Pushing the curb into the fresh foundation or causes a full-surface contact between the foundation and Curb as the concrete forming the foundation less forced to flow horizontally to the curb too enclose.
- An advantageous embodiment of the invention provides that Recess in the area of the side surface as a chamfer to to realize which in the bottom of the curb expires.
- a shaping is the insertion the curb further facilitated in the fresh foundation as the curb through this chamfer towards the foundation is formed wedge-like.
- the recess in the area of three Forming side surfaces meet. hereby also creates a wedge-like design of the foot area of the curb with the above advantages.
- An expedient embodiment of the subject invention plans to keep the curb in a foundation which is T-shaped or L-shaped and preferably at least two curbs below or into the foundation of the road surfaces.
- Such a thing Foundation serves as a tilt protection for the boron, which in capable of acting on the curb forces and moments spread over a large area on the ground or in the Forward the foundations of the road surface.
- a curb suitable which is trapezoidal in plan view is formed or its side surfaces, which opposite curbs opposite, a miter exhibit.
- FIG. 1 shows a plan view of a detail of a roundabout 1.
- 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 designed as a paving surface 11, which is constructed from individual paving stones, not shown in Figure 1.
- 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.
- Figure 2 shows a plan view of a section of a straight road running traffic area 14. This consists in analogy to the roundabout shown in Figure 1 a first running surface 3, which over a row 15 of Curbs 5 merges into a second running surface 6.
- the second running surface 6 lies in a plane F which is deeper lies as a plane E, which through the first running surface. 3 and flat surfaces 9 of tops 8 of curbs 5 is formed.
- the gentle transition between these levels E, F is by an inclined surface 10 on the tops 8 of Curbs 5 ensures which together in one sloping plane G lie.
- the first running surface 3 act forces from approximately one direction b5 on the curbs 5.
- the direction from which the forces when driving on the curbs 5 act in detail Depending on the angle in which the respective vehicle ascends. Generally, however, at the roundabout and at the straight road from attacking forces in a spike Go out 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 Figures 7, 8) 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 shows a view of the upper side 8 of the curb 5.
- the curb 5 has a width B 5 of about 50 cm and a depth T 5 of about 30 cm.
- the inclined surface 10 of the top 8 has in the vertical projection a width B 10 of about 8 cm.
- FIG. 5 shows a view of the rear side 17 of the curb 5.
- the curb has a total height H 5 of about 35 to 40 cm.
- the chamfer 25 has a width B 25 of about 15 cm and a height H 25 of about 7 cm.
- the wedge surfaces 30 formed in the corner regions of the underside 20 by the recesses 22 have a height H 30 of about 15 cm and to the side surfaces 16, 17 a width B 30 of about 5 cm.
- FIG. 6 shows a view of the right side 18 of the curb 5.
- 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.
- FIG. 7 shows a cross-section through the roundabout 1 shown in FIG. 1, the latter being reproduced in idealized form.
- the running surface 6 passes over the curb 5 in the running surface 3, which is formed from individual paving stones 31.
- the running surfaces 3, 6 are built on foundations 32, 33.
- the curb 5 is held in a foundation 34, on which the curb 5 rests with a bottom 20 and which partially abuts a front side 16 and on a back side 17 of the bristle 5 and engages in recesses 22.
- a groove 23 allows the concrete foundation to dig into the curb 5 and take over shear forces of this.
- Wedge surfaces 30 at all four projecting into the foundation 34 vertical edges of the curb 5 allow the foundation concrete between adjacent curbs penetrate and form wedge-shaped projections in these places, which counteract in particular twisting of the curb 5 about a vertical axis h, as curb in the lower part by a total eight contact surfaces is held.
- the T-shaped foundation 34 engages under the foundations 32, 33 of the running surfaces 3, 6 and is thus better suited to accommodate the curb 5 and the foundation 34 acting torques, which by acting from the direction of the arrow b 1 on the curb 5 forces be generated.
- the curb 5 and the foundation 34 act as a monolithic unit 35, which due to their high weight and shape can absorb forces without being damaged or without being moved.
