Definitions
- Traffic control device usable as a central partition and roadside barrier
- the invention relates to a traffic control device with a profile on both sides for use as a central separation of roads or with a profile on one side for use as a roadside barrier, the profile having an essentially vertical lower side surface, one with a leading edge adjoining it, has an obliquely outward running surface and, above that, a deflecting strip which is offset outwards relative to the running surface and acts on the vehicle below the body.
- a guiding device which is designed differently in principle and only affects wheels and steering, has been developed in Sweden (Tric-Bloc, see eg VDI-News No. 23, June 8, 1979). It uses two concave-curved, prism-shaped surfaces of 0.8 - 1 m in height that use the steering geometry of a running wheel that is again deflected to the direction of the road for slow redirection without contact with the body. Driving tests have actually shown an insurmountability for rolling vehicles with smaller impact angles.
- the object of the invention is to provide a guiding device which only acts on wheels and steering, which fulfills all the requirements set forth and avoids the disadvantages of known such devices.
- the invention achieves the stated object in that the ramp surface from the ramp edge arranged below the height of conventional tires at least to the base of the solder applied to the deflector bar runs increasingly steeply, and that this base point lies in the central region of the vertical distance between the leading edge and the underside of the deflector bar.
- the interaction of the projecting deflecting strip with the underlying contact surface is of crucial importance for the invention. If the deflector protrudes too far, it makes the ramp surface largely ineffective; one does not only dispense with a gentle redirection in cases that are harmless per se, but also with the advantages that result from lifting the vehicle by means of the ramp surface. The main reason for this is that the deflector bar is arranged somewhat higher and the tilting moment on the vehicle can thus be reduced when the vehicle is raised
- Wheels that is also raised body, meets the deflector strip.
- the height of the leading edge above the street level is to be chosen so high that the usual tire thicknesses - just yet - do not cause the vehicle to tip over due to rim contact. In this sense, a height of around 6 cm has proven itself.
- 1 is a longitudinal view of a guide device that can be used as a center separation
- FIG. 3 shows a modification of the device according to FIG. 1 for use on high-speed roads
- Fig. 4 corresponds to Fig. 1, the partially cut, schematic representation of a vehicle being added to explain the mode of operation
- FIG. 5 shows a partially sectioned side view of two articulated, movable individual elements of the guide device
- FIG. 7 shows a side view of an end element
- FIG. 8 shows a longitudinal section along the parting plane indicated in FIG. 7,
- Fig. 9 shows the associated longitudinal section.
- the profile consists of a vertical lower surface 1, which merges into a curved run-up surface 3 in the run-up edge 2, which is followed by the deflector strip 4 at the end of the steep flank.
- the run-up edge 2 lies at 5 - 6 cm high enough that a bumping or throwing wheel can just overcome it; the deflector bar is so wide that it can withstand a striking wheel without damage with a possible sheet profile reinforcement 7; it is set back so far relative to the run-up edge 2 that the run-on or spinning wheel can be raised further by the lower part of the run-up surface; compared to the steep upper flank, however, it is so overhanging that greater frictional forces and thus a tendency of a rolling wheel to climb are avoided.
- Fig. 1 shows an embodiment as a center partition with a profile formed on both sides
- Fig. 2 shows the design as an edge deflector with a profile on one side
- 3 shows a possible modification of the profile for high-speed roads.
- a top wall 6 is attached here as an additional deflector above the deflector strip 4 so that contact with the protruding parts of the front parts in the event of a collision at acute angles further is avoided, possibly climbing wheels but find appropriate resistance.
- the heel 12 between the elevation and the upper part serves as a guide groove for the inclined wheel, which prevents further climbing and thus rolling over from the gang.
- the guide device acts as a rigid, body-active barrier.
- an enlargement of the profile shown can be used e.g. on a scale of 1: 2 or an enlargement of only individual profile parts are used. This carries e.g. the increased tendency to climb and the strong pressures of the rigid rear wheels at high loads. At the speeds that are only low, passenger cars are also rejected by the twice as large tread surface without body contact.
- passages can be arranged in the base of the element or below it in the carriageway.
- control device The function of the control device according to the invention is subsequently described with reference to FIG. 4.
- the guide device is preferably made of hard, unbreakable and pressure-resistant material, for example concrete, with steel reinforcements. But also other materials, such as metal, plastic, asphalt can be used as solid or hollow profiles with concrete pouring in a manner known per se.
- the fender strip 4 can e.g. of 3 mm sheet steel to be covered to make contact with sharp rim parts with low friction and damage.
- the upper surface of the guide device can be provided with a low-friction covering that closes the surface.
- control device Two types of manufacture of the control device are preferably possible:
- Prefabricated elements can be of any length, for practical reasons e.g. Individual elements measuring 4 m with the specified profile, with cast-in lifting hooks or other attachment points at the top.
- They can be placed on the road as a mobile barrier without anchoring, but they can also be glued, anchored, or anchored as a stable barrier or enclosed by the rolled or cast-on road surface with the correspondingly longer base.
- the stability of the element chain is based on the movable elements in the lateral direction on the axial connection of the elements with each other (Fig. 5,6). Thrust and train in the direction of the lane are absorbed by the mass of the adjacent elements, thrust in the transverse direction first by the displacement of the element, then by the articulated element connections, for example in the form of the pin joint 8 shown by stuck.
- the molds for the manufacture of the prefabricated elements consist of the base, which corresponds to the top surface of the element in the production, which is preferably upside down, from the two side profile shapes which are pressed against this base surface and from the two end parts which are plug-like into the Side parts are inserted and thereby give them hold and fit. Cylinders for the bolt recess in the overlying or for the threaded pin fixation in the underlying overlaps are attached to the end molds.
- the hard profiles for the deflecting edge are inserted on the mold base and brackets for characters to be attached later are glued on at points.
- curved curve elements consist of flexible, approximately rubber-like material. They are pressed on both sides of the base area produced in the required radius. Exact adherence to the profile shape in all sections is guaranteed by profile clips attached at appropriate intervals.
- the overlapping end parts are shaped by the inserted plugs, which are also used for the straight elements. As a result, the flexible side part shapes can be used for a wide variety of curves.
- OMPI radii can be used.
- Other manufacturing processes such as extrusion presses etc. are also possible in a known manner
- Start and end parts of the guide device are shaped corresponding to FIGS. 7 to 9. They can be placed at low speeds without anchoring, but they can also be glued or placed with a recessed central groove over steel bolts 10 driven into the street and the cavity filled with concrete 11 from behind
- Continuous guiding devices cast on site by sliding shells - concreting machines are continuously applied to the road surface using pre-fabricated, simple reinforcement using the corresponding sliding joint surfaces. Its base can also be led deep.
- the hard professionals for the deflector bar are inserted in guides on the formwork surface and screwed or hooked together in the longitudinal direction.
- Various brackets can be placed in the still soft concrete. After the concrete has been cemented, the final road surface is applied or rolled on, while maintaining the height of the leading edge.
- the guiding device can also be produced together with the road surface construction in one work step.
- the beginning and end parts serve the corresponding parts of the prefabricated elements, the connection surface allowing a firm connection, for. B. by toothing or v binding reinforcing bars.
