Definitions
- the invention relates to a concrete wall element for a restraint system on streets.
- the known wall elements can separate the oncoming traffic areas from a certain lane width, they can no longer be used because they take up too much effective installation range. In such cases there are many Forced road operators to rely on traditional methods such as double guidelines fall back to separate different lanes. But how has shown, these security measures are far from sufficient to Avoid road traffic accidents.
- Known metal wall elements can be made relatively narrow, but they are much more resilient than concrete wall elements.
- the object of the invention is therefore to provide a wall element of the type mentioned at the outset, which enables a sufficiently stable installation with a relatively small effective width.
- the increased stability of the wall elements caused by the lateral support elements tipping over allows the wall element to be made of concrete and thus an elevated one to ensure mechanical strength of the same with a relatively small width.
- the wall element In order to can a cross-sectional widening in the otherwise common with New Jersey concrete wall profiles lower area, which is the field of application of the invention Wall element increased accordingly.
- a structurally and technically favorable embodiment of the invention can consist in making the cross section of the wall element trapezoidal.
- a high resistance with a relatively low weight of the wall element can then be achieved if the support elements are formed from metal.
- On top of the Support elements can be a floor marking in the form of a film or a coat of paint be provided.
- the Support elements are formed by steel profiles and are anchored in the wall element.
- the steel profiles are L-shaped Have cross-section, with the shorter L-leg springing back on each bevelled surface of the wall element and the longer L-leg from Wall element protrudes at an acute angle to the floor, so that - in cross section seen - the profile ends of the L-shaped steel profiles support the wall element on the floor.
- the steel profiles connected in this way to the wall element result in a stable Support in the lower area of the wall element, so that the wall element tilts over can be effectively avoided.
- the profiled design brings on the one hand Material savings and is also suitable to provide additional elastic bearings.
- the bearing elements can be positively inserted into the the support elements formed can be inserted and parallel to the bottom of the Form the wall elements of the stand areas.
- the wall elements are elastic on the bearing elements, which are compressed as far as possible in a collision be that the support elements come into contact with the ground and against one Upset the wall element.
- bearing elements can then withstand the pressure acting on them withstand if according to a further embodiment of the invention bearing elements as Elastomer bearing elements are formed.
- the standing surfaces of the bearing elements can be a profile, preferably with a triangular cross section, which the friction of the Bearing elements increased on the underground.
- Adequate elastic support can be created if according to another Embodiment of the invention, the bearing elements on opposite sides and in Area of the ends of the wall element are arranged.
- the invention relates to a guide wall for traffic routes, with concrete wall elements, which have drawstrings running inside, the ends of which end with Engagement elements are provided, in which coupling tension members for non-positive Connection of adjacent wall elements can be used, especially under Use of a wall element according to the invention.
- the wall elements that are connected to each other on the end face are in a side Start-up deflected by a motor vehicle depending on the force of the impact, the largest deflection is naturally given at the accident site itself.
- the clutch pressure members set the clutch tension members under preload, whereby an optimal frictional connection between the wall elements of the Guide wall according to the invention can be achieved without play, with a lateral Impact of a motor vehicle results in less displacement or deflection. By the lower postponement in accidents can result in oncoming traffic accidents can be reduced.
- the clutch pressure members are formed by threaded screws with a shaft part and a head part, and a threaded sleeve is inserted in each end face of each wall element, in which the threaded screws can be screwed in, so that the head part of the threaded screws on the opposite end face of the adjacent wall element can be supported.
- a suitable one can be turned by turning the threaded screw in the threaded sleeve Preload of the coupling tension members reached and thus the train connection free of play being held.
- the coupling pressure members are formed by threaded screws with a shaft part and a head part, the Head part is connected to a support plate, and the clutch pressure members in recesses are used on opposite end faces of the wall elements, one in each Deepening a sleeve for receiving the shaft end of the threaded screw and Support a threaded nut screwed onto the shaft part is provided and the Support plate is supported on the inner wall of the opposite recess.
- Another embodiment of the invention may consist in that in the area of At least one joint between the end faces of adjacent wall elements flat, elastic pressure compensation element is arranged positively.
- the wall is deflected in the event of a collision and the individual wall elements shifted, the resulting compressive stresses on the Edge areas of the wall elements can, however, be evened out to such an extent that none Part of the guide wall elements flake off. Furthermore, the uniform Forwarding of the resulting pressure from the outside into the wall elements also one The tensile strength of the entire wall bracing in the longitudinal direction is increased.
- the pressure compensation element is wedge-shaped because it thereby better adapted to the shape of the gap occurring between the wall elements is.
- FIG. 1 shows a concrete wall element 1 for a restraint system on roads with trapezoidal cross-section, which is arranged by means of the end face Engagement elements 15, 16 are connected to other similar wall elements can to build a restraint system.
- Support elements 10, 11 formed at least partially along the length thereof are provided, which are non-positively connected to the wall element 1.
- the wall element 1 is prevented from tipping over, but nevertheless one allows small width of the wall element cross section.
- the support elements are over the entire length of the wall element 1 extending steel profiles 10, 11 with an L-shaped cross section formed and anchored in the wall element 1 by anchor bolts 8, which also with the reinforcement of the wall element 1 can be connected. Any are within the scope of the invention Changes in the shape of the support elements possible.
- the shorter L-leg 81 borders on a recessed beveled surface of the Wall element 1 and the longer L-leg 80 is from wall element 1 in one acute angle to the floor, so that - seen in cross-section - the profile ends the L-shaped steel profiles support the wall element 1 on the floor as soon as this one Is exposed to load during a start-up event.
- elastic bearing elements 4, 5 are preferred made of an elastomer, inserted into the support elements 10, 11, whereby the profile ends at a load, such as when moving sideways on the wall element 1, touch the floor and prevent the wall element 1 from tipping.
- Other elastic materials can also be used be used to form the bearing elements.
- the bearing elements 4, 5 are positively in the by the support elements 10, 11th formed cavity used and form parallel to the underside of the wall element 1 flat Stand space.
- the bearing elements cause elastic storage of the Wall element, whereby an impression of the same in the floor or underground, e.g. in the asphalt surface, if it becomes warm and soft in summer, is prevented.
- Another advantage is the increased friction caused by the bearing elements, which causes displacement of the wall element 1 in the event of a side impact of a motor vehicle Opposed resistance.
- the elastic bearing elements 4, 5 are preferably on opposite sides and in the region of the ends of the wall element 1.
- the elastic bearing elements 4, 5 are dimensioned as a function of Dead weight of the wall element 1 and depending on the desired Friction values. A vote can e.g. due to different shore hardness and / or Lengths of the bearing elements happen.
- Fig. 9 shows a section of a guide wall for traffic routes for which the support elements 10, 11 according to the invention can be used.
- the wall elements 1, 1 ' have tension bands 34, 35 and 34' running inside them, 35 ', the ends of which are provided with end-side engagement elements 15 and 15', in which Coupling tension members 21 for the frictional connection of each adjacent Wall elements 1, 1 'are used.
- the invention provides that the each adjacent wall elements 1, 1 'additionally by coupling pressure members 55, 57 are connected in or on opposite end faces of the wall elements 1, 1 ' are supported.
- the coupling pressure members are by threaded screws with a shaft part 55 and a head part 57 and one in each end face of each wall element 1, 1 ' Threaded sleeve 56 inserted.
- 9 shows the corresponding end face of the wall element 1 shown, in the threaded sleeve 56, the threaded screw 55, 57 is screwed.
- the head part 57 of the threaded screws is on the opposite one End face of the adjacent wall element 1 'supported.
- the coupling pressure elements can also be used for baffles with wall elements without side Support elements may be provided.
- the clutch pressure members are the Guide wall according to the invention by threaded screws with a shaft part 65 and a Head portion 67 formed, which is connected to a support plate 69 which is connected to one by a Steel insert reinforced inner wall 70 of two opposite recesses is supported.
