Definitions

• the present invention relates to a device " for securing a road channel passage against the frontal impact of a vehicle that has strayed from the higher road surface.
• the invention now aims to provide a safety device which prevents a vehicle from colliding with the front side of the street channel passage.
• the safety device according to the invention is distinguished by the fact that it has a trapezoidal drive-up plate made of a material that absorbs the vehicle load, such as reinforced concrete, plastic, etc., which can be placed on the carriageway slope with a trapezoidal side, with its larger trapezoidal base on the front side of the street channel passage at the height of the carriageway and with its smaller trapezoidal base on the street channel bottom as well as with its other trapezoidal side on the street channel slope opposite the carriageway and / or an area adjacent to the street channel and lower than the carriageway level, the Ramp plate in the area of the smaller trapezoidal base is provided with a water passage opening covered by a grid.
• an inclined ramp surface covering the road channel in front of the end region of the road channel passage becomes a road surface that has strayed from the road Vehicle created on which the vehicle hits the wheels and on which it is braked.
• the impact energy is absorbed to the ground and the road channel bottom by the support of the ramp plate on '.
• the drive-on surface is also connected to the surface adjacent to the road channel via an edge, the stray vehicle may be deflected onto the surface adjacent to the road channel via the drive-on plate.
• the water passage opening in the base plate of the street channel in the drive-up plate ensures that the effect of the street channel is fully maintained even in heavy rainfall.
• the ramp is provided on the trapezoid side facing away from the road with a triangular extension, which can be supported on the one hand on the front side of the street channel passage in alignment with the larger trapezoidal base and on the other hand at the transition between the street channel and the adjacent surface.
• This extension which is preferably releasably connectable to the drive-on plate, merges into the actual drive-on plate at an obtuse angle and ensures a continuous drive-on surface in the area between the transverse lane or the like. and the area adjacent to the street canal.
• the ramp plate forms an angle of approximately 20 ° with the street channel sole.
• receiving members or the like are in the ramp plate and preferably also in its extension. cast in, which is an easy laying of the finished part, e.g. Allow precast concrete, manufactured road component.
• FIG. 1 shows a top view of a safety device according to the invention
• FIG. 2 shows a section through the safety device along the line II-II in FIG. 1
• 3 shows a vertical section through the installed safety device, the reinforcement of the drive-on plate not being shown for the sake of simplicity, and
• FIG. 4 shows a plan view of a further exemplary embodiment of the invention.
• the safety device has a drive-on plate 1, which is produced, for example, as a prefabricated reinforced concrete part and, in plan view, is designed as a trapezoid with equal legs.
• the ramp plate 1 is placed according to FIG. 3 with its one trapezoidal side on the carriageway embankment B and with its smaller trapezoidal base 1 'on the sole S of a road channel K laterally adjacent to the carriageway F via the embankment B and for this purpose is on the underside of the plate in Provide a chamfer in the area of the smaller trape ⁇ base 1 '.
• the drive-on plate 1 also supports itself in the area of its larger trapezoidal base 1 ′′ also via a bevel provided on the underside of the plate on the front side D ′ of the street channel passage D and with its other trapezoidal side on the other bend B ′ of the street channel K or at the transition of one area F "ao adjacent to the road channel K, which is, for example, a field and lies lower than the roadway F.
• the oblique angles of the bevels of the larger and the smaller trapezoidal base 1 "or I 1 are expediently made such that the ramp plate 1 in the installed state forms an angle of approximately 20 ° with the channel base S, as can be seen from FIG. 3.
• a passage opening 4 is formed in the mounting plate 1, ⁇ urcn which rainwater can mn ⁇ urchtr ⁇ ten and which is covered with a grid 5.
• the ramp 1 is also provided in the example shown with four anchoring elements 6 anchored in its steel reinforcement ST, such as hooks or eyelets, via which the ramp plate can be received for transport and laying.
• anchoring elements 6 anchored in its steel reinforcement ST, such as hooks or eyelets, via which the ramp plate can be received for transport and laying.
• the drive-on plate 1 shown forms a drive-on surface for one from the roadway F (direction of travel P) over the boscung B vehicle that arrives on the drive-on plate, which is " braked on the plate or brought to a standstill, the drive-on plate transmitting the impact energy to the ground.
• a ramp plate extension 7 is provided according to FIG. 4, which is a triangle in plan view is formed and with its triangular base on the other, smaller road channel embankment B 'or at the transition to the surface F "and with its two other triangular sides on the ramp 1 and on the end face D' of the road channel passage D in alignment with the larger trapezoidal side 1" supports the drive-on plate 1.
• the drive-on plate extension 6 is preferably releasably connected to the actual drive-on plate 1 and forms an obtuse angle with it, owing to the level difference of the surface F ′′ with respect to the main drive way F.
• the extension 6 is also conveniently manufactured as a finished part and e.g. screwed to the ramp plate 1 by means of threaded bushings and screw-in pins provided in the ramp plate 1 and in the extension 6. This connection is only indicated schematically at 8 in FIG. 4. It goes without saying that the extension 6 is also provided with bevels, at least in the area of its support on the front side of the road channel, which ensures that the extension is properly supported.
• the safety component according to the invention can be made not only from reinforced concrete, but also from other load-bearing materials, e.g. be produced as a plastic plate, provided that the necessary load-bearing capacity for receiving the vehicle weight remains guaranteed.
• the described exemplary embodiments can be modified in various ways within the scope of the general inventive concept in order to be adapted to the particular needs of the streets or the street channel construction. This applies in particular to the bevel angles on the underside of the plate and to the dimensions of the trapezoid and the triangular extension.
• the length of the larger trapezoidal base is approximately 2.5 m and the trapezoidal height can also be about 2.5 m, while, for example, the 'smaller trapezoidal base can have a length of 60 cm.
• the thickness of the ramp plate can be selected with about 15 cm for precast reinforced concrete.
