Abstract

Slab (1) for tracks (8) of road traffic, said slab (1) forming a ramp between the upper surface of a platform (5) raised for the reduction of the speed of the vehicles and the upper surface of the track (8) circulation, characterized by the fact that the height of the slab (1) in its closest part (3) to the platform (5) is greater than the height of the slab (1) in its furthest part (2) of it.

Description

Slab.

The present invention relates to a slab applicable to elevated platforms for speed reduction of vehicles.

Background of the invention

The use of raised platforms is known on roads for the transit of vehicles with the objective of reducing their speed.

These platforms are usually built on roads residential areas, at the entrance of urban centers, or on roads peripherals in which circulation at speeds is not allowed high. These platforms force the driver to reduce the speed to overcome them without problems.

The platforms described consist of an area central whose surface is elevated about 10 or 15 centimeters above the road surface. On both sides of the area There are both up and down ramps that facilitate that vehicles can overcome the platform without having to Stop the vehicle completely.

These ramps are constituted by a slab or flat tile. This forces that before placing the slab you have that form an earth slope or other support material on the The slab is placed inclined.

On other occasions, the ramps are the own asphalt of the road, resulting in the asphalting of the area more next to the most complicated platform and having to build previously the slope.

Description of the invention

The objective of the present invention is to solve the disadvantages of known devices in the technique, providing a slab for roadways, said slab forming a ramp between the upper surface of a elevated platform for reducing the speed of the vehicles and the upper surface of the road, characterized by the fact that the height of the slab in its part closest to the platform is greater than the height of the slab in its  furthest part of it.

Preferably, the height difference between the part of the slab closest to the platform and the most part remote is substantially equal to the difference in height between the upper surface of the road and surface top of the platform.

Thanks to these characteristics, the slab of the invention allows to form the ramps of the platforms so much faster and easier. The ramp is configured by the same slab, and it is not necessary to prepare a slope before the placement of it.

Advantageously, the slab comprises a surface upper which includes a first substantially curved convex section tangent to the upper surface of the platform attached to a second curvoconcave section substantially tangent to the surface top of the track.

Thus, the transition between the surface of the track and the platform is more progressive, and the vehicles They can overcome it more safely.

According to an embodiment of the present invention, the base of the slab comprises a plurality of grooves transversal.

These grooves favor the fixation of the base of the slab on the surface on which it rests, increasing the stability of the piece at the time of placement and in its functioning.

Brief description of the drawings

In order to facilitate the description of how much It has been exposed above are attached some drawings in which, schematically and only by way of non-limiting example, represents a practical case of realization of the invention, in the which:

Figure 1 is a perspective view of a slab of the invention;

Figure 2 is another perspective view of a ramp formed by slabs according to the present invention;

Figure 3 is a sectional view showing the arrangement of the slabs of the invention when they form a ramp.

Description of a preferred embodiment

As can be seen in Figure 1, the slab 1 of the invention comprises a body, preferably of concrete, with two ends 2, 3, the height of end 3 being with respect to the base 9 of the slab 1 greater than the height of the end 2 Regarding it.

In figures 2 and 3 the arrangement of slabs 1 to form an access ramp to a platform 5. Slabs 1 comprise an upper surface 4 that it comprises a first section 6 curved convex substantially tangent to the upper surface of the platform 5 attached to a second section 7 curvoconcave substantially tangent to the upper surface of track 8.

Thanks to the height of the adjacent end 3 to platform 5 is greater than the height of end 2 adjacent to the track 8, slab 1 can be placed directly on a floor 10 plane without having to previously form a slope inclined.

The upper surface 4 of the slab 1 allows, thanks to its sinuous profile, that the vehicles that cross the platform 5 reduce speed gradually and eliminate sudden reactions that cause the slabs used in the present. The fact that there are no sudden changes of trajectory on surface 4 also lengthens the duration of slabs 1, especially if the track is frequently used by Heavy vehicles.

Slab 1 is provided in its base 9 of about 11 transverse grooves that help fix more stable the piece.

As can be seen, the ramp represented in the present embodiment is formed by several slabs 1 of different coloration arranged alternately, which helps identify more efficiently the presence of the platform 5.

Although in the embodiment described the ramp is formed by a plurality of slabs 1, you could also provide a single slab of greater width that forms the entire ramp.
