Definitions

  • the invention relates to a separating device which consists of lined up, interconnected concrete elements which are arranged in a wall-like manner between opposing carriageways or on the edges of roads or the like, the mutually identical concrete elements having a prism shape and with their perpendicular prism bases in the wall-shaped one Arrangement in the manner of end faces face each other and have a polygonal cross-sectional shape and a correspondingly divided jacket shape, in which one surface is designed as a standing surface (standing surface), while the other surfaces run perpendicularly and / or diagonally ascending or horizontally and as sliding surfaces , Visible surfaces, mounting surfaces or the like are configured.
  • separators Since separators have the task of catching vehicles coming off the road and preventing such vehicles from striking one next to them running on the opposite lane or stray from the road at the side of the road and endanger adjacent areas, the concrete elements sometimes have to withstand quite large forces. In known separation devices, a single element cannot absorb such impact forces without being displaced. For this reason they are mechanically connected to one another in known separation devices with mutually facing end faces by complicated coupling devices.
  • the invention has for its object to provide a separating device of the type mentioned, in which concrete elements are used, which are designed so that, despite the possibility of creating curved wall profiles, they border one another without gaps, one Frontal impact against a sharp corner reliably prevent that they can be easily connected to a partition or the like without great assembly work and can also be used universally.
  • the above-mentioned separating device is characterized according to the invention in that the concrete elements are designed as oblique prisms with mutually parallel end faces, which are inclined at an angle of 45 ° to the prism length, that these end faces in the wall-shaped arrangement of the concrete elements on the the end facing the direction of traffic on the side facing the traffic run at an obtuse angle to the length of the prism and, in the wall-shaped arrangement, are connected to one another in a positive and non-positive manner, at least partially in contact with each other at least in the event of a load.
  • the concrete elements have vertical, but for Length inclined at an angle of 45 °, and they are each arranged so that the corner opposite to the direction of traffic, ie the angle between the end face and the outer surface is obtuse, ie 135 ° in size.
  • the concrete elements are offset so that they touch each other with the end faces at least in some areas.
  • This configuration is independent of the specific cross-sectional shape of the concrete element in each case. Concrete elements in the shape of a truncated pyramid, trapezoidal or the links in cross-section can thus be designed differently, without the cross-sectional shape having an influence on the special configuration of the end faces and thus impairing the advantages which result from this configuration.
  • the inclined end faces make it possible to erect dividing devices in an arc shape, i.e. to provide road or road curves with separating devices, and that even in this case a complete coverage is ensured on the concave side of the arch that is at risk.
  • the described force-transmitting effects become effective, and there is the possibility of reliably avoiding a frontal impact on a corner at a 90 ° angle. Since the concave side is always the endangered side of roadways, which must absorb impacting vehicles and which is subjected to high forces in the event of an impact, the separating device designed according to the invention offers a level of safety not previously achieved.
  • the concrete elements of the device designed according to the invention are always directed at an obtuse angle to the traffic, it is necessary to produce a left and a right version, depending on whether the concrete elements, seen in the direction of travel, to the left of the road or to the right the lane. If the concrete elements are to be used in areas with left-hand traffic, the requirements for left-hand or right-hand execution are reversed.
  • the separating device optimally fulfills its purpose, the requirement mentioned several times must be made that the individual element is able, due to its own properties, to absorb the impact of a vehicle with as little or as little as possible slipping.
  • One way of fulfilling this requirement is to make the concrete elements difficult to make so that they can be moved with difficulty by an impact due to their high weight and thus the mass of the support as well as their high resistance to displacement. But there are limits to this path.
  • the manageability when transporting and setting up the concrete elements limits the weight increase.
  • the concrete elements of the separating device designed according to the invention can only be made as long and thus as difficult as is manageable, etc. in the context of manageability. However, this path can only be followed without disadvantages if the concrete elements are to be used to create separating devices which are straight or only slightly curved.
  • the concrete element is coated with an elastic material on the end faces at least in areas near the edges, on the outer surfaces at least in areas near the end faces. This protects the surfaces. The friction between the parts increases and with it the power transmission from one element to the other, so that the elements stick together like a closed wall.
  • Elastic knobs which are arranged in the surface of the concrete element on the end faces or the standing surface, have the advantage that they offer mutual resistance from the end surface to the end surface, so that a Overlapping end faces touching each other is avoided.
  • the elastic knobs on the base adapt to the surface and increase the resistance to displacement. However, this measure also makes installation work easier and the preparation of the sub-floor no longer needs to be so precise because the knobs compensate for irregularities.
  • the elastic knobs allow the concrete elements to be placed very close to one another, so that they are already in contact with one another, so to speak, without causing any disadvantages. Concrete elements are also subject to thermal expansion in strong sunlight. The elastic knobs absorb these thermal expansions by deforming.
  • the concrete elements can be placed against one another with the end faces on pre-pressure, so that they are clamped or clamped in the frame of the separating device. Thermal expansion is absorbed and compensated for in the manner already mentioned within the elastic material. It is of particular advantage in this development that pointed corners are generously rounded as far as the concrete body is concerned and that the addition to the target shape is provided by the elastic material he follows. In this way, safety is increased to a considerable degree, because even in the most adverse circumstances, vehicles hitting in extremely disadvantageous directions encounter resilient material, which reduces the impact and reduces impact damage. But the concrete element itself also benefits from this development, because the corners and edges of a concrete body are in danger of being destroyed, but an elastic material absorbs forces that could damage the corner of a concrete body through elastic deformation.
  • An alternative or additionally applicable development of the separating device is characterized in accordance with claim 7, characterized in that the standing surface of the concrete element is divided into at least two partial surfaces by means of at least one channel which is open at the bottom and runs transverse to the length.
  • the displacement resistance of the individual concrete element increases against displacement forces in the longitudinal direction and against forces acting obliquely to the length, because the gravel-like or sand-like subsoil to a certain extent penetrates into the grooves.
  • a further advantageous embodiment of the separating device according to the invention is that the base surface of the concrete element is divided by offset, for example cross-shaped grooves, which form individual feet.
  • the separating device If it is not possible with the above-mentioned further developments to design the separating device to be sufficiently secure for displacement, for example because the impact forces to be expected are extremely high, or because severely curved dividing or sliding walls are to be erected, in which the concrete elements must be even shorter than the compromise measure allows, then the development according to claim 9 is recommended, which is characterized in that the concrete elements on their end faces, approximately in the longitudinal center plane, on the base surface has open, lower slots of limited height, the cross section of which tapers towards narrow slot openings towards the end face is, and that in the lower slots of two, with their end faces adjoining concrete elements the slits are adapted to the shape, tapered from both ends towards the middle of its length, lower double-conical connecting bar.
  • This training can be used in addition to those already mentioned or alternatively.
  • successive concrete elements are mechanically connected to one another, as is already the case with the known separating device mentioned at the outset, it avoids the disadvantages associated with the known. Since the end walls are at an angle of 45 ° to the length of the concrete elements, there are no gaps and no right-angled corners that would cause a frontal impact. However, the considerable manufacturing and assembly work is also avoided, since the slots open from the base allow the double-conical connecting bolts to be placed on the ground and the concrete element to be placed on the connecting bolt from above. So there is no coupling, connection or assembly work.
  • the double-conical shape of the connecting bar serves to absorb any tensile forces that may have caused the contacting end faces of two concrete elements to be removed from one another. Even if the double-conical connecting bolts are adapted to the shape of the slots, this does not mean that they must fit into the slots without play. If you allow a certain amount of play and if you make the double-conical connecting bolts long in the middle, narrow area, the concrete elements can also be used when setting up a curved separating device.
  • the connecting bolt as a steel-reinforced concrete bolt trained, designed to withstand certain loads up to certain values against longitudinal and transverse forces to the concrete elements and is provided on the middle of the length with a concrete breaking point that yields under permanent load when the steel reinforcement remains under load.
  • This development relates to the design of the connecting bolt in detail. If it is designed as a steel-reinforced concrete bar, it also has a high resistance to shear or compression, so that it is not only able to absorb and transmit pushing forces that act in the direction of pull, but primarily and to a particular extent pushing forces that generate pressure. It is essential, however, that a predetermined breaking point is created in the middle. This predetermined breaking point enables transverse forces to be absorbed up to certain heights. Even if the connecting bar breaks, the steel reinforcement maintains the connection between the two concrete elements. The success of this measure is that, in the event of a severe impact, slight displacements occur, but the mutual connection of the concrete elements within the separating device is not canceled or destroyed.
  • An alternative solution for a mutual connection of the concrete elements within the separating device is characterized in accordance with claim 11, characterized in that the concrete elements on their end faces, arranged symmetrically to the longitudinal median plane, extending from the uppermost surface area to the end and extending in cross section at their ends remote from the end face, have open top slots on the end faces and that in the top slots of two, with their end faces adjacent concrete elements, of above, an upper connecting bar is used, which is cross-sectionally adapted to the shape of two adjoining, upper slots and consist of metal coated on the outside with elastic material.
  • the laying or assembly work may be even easier than with the aforementioned solution.
  • mutual connections of concrete elements can be produced even with a strong curvilinear course, because the slits extending downwards from the upper lateral surface allow the upper connecting bolts to be made of sheet metal, which is elastically and plastically coated, in accordance with the Situation pre-bent and inserted into the slots.
  • Such upper connecting bolts can be dimensioned almost arbitrarily. This is because it can be realized that such bars break due to their material properties and dimensions before the concrete element is damaged. It is much easier to replace a damaged top tie after an impact than to replace one or two concrete elements that have broken due to an overload.
  • the fact that the top connecting bolts are coated with an elastic-plastic coating means that they are also protected against corrosion from the weather.
  • the upper slots extend up to the transport threads of the concrete element and that the upper connecting bolts can be brought into engagement with the transport threads.
  • Concrete elements usually have transport threads, with the help of which the handling during transport and Laying work is made easier.
  • This transport thread can advantageously also be used for fastening upper connecting bolts if the slots extend as far as the transport thread.
  • the separating device designed according to the invention can be used universally. It can be created both as a temporarily usable separating device and as a permanent device.
  • the development according to claim 13 is suitable, which is characterized in that the adjoining end faces of two adjacent concrete elements are glued together.
  • the mutual bonding of adjacent end faces means that the mutual connection is absolutely tight and permanent. It can be done by gluing concrete to concrete surface or also by gluing the elastic materials applied to the concrete surfaces. Where separating devices are curved and consequently wedge-shaped gaps are formed on the convex side between two end faces, suitable masses can be poured out.
  • the separating device designed according to the invention can also be used in a permanent version for other applications, for example as a supporting or embankment wall.
  • the further development according to claim 14 is advantageous, which is characterized in that the concrete elements in or in one of the jacket surfaces facing away from the traffic have a recess which is undercut in cross section, for example, dovetail-like and which each extends a distance from the end face Longitudinal direction of the concrete element extends and that in the two recesses of two, adjacent to each other with the end faces, adjacent concrete elements, a bridging bar with at least part of its cross section is inserted into the recess.
  • the bridging bars which positively engage the concrete elements on the back, transfer local embankment pressures from concrete element to concrete element.
  • the separating device designed according to the invention is extremely versatile. Thus, it is provided according to claim 15 that exposed and visible lateral surfaces of the concrete element are provided with colored and / or retroreflective markings.
  • At least the uppermost surface of the concrete elements has receiving openings for posts or the like.
  • the extended ends of these slots can possibly already be used as receiving openings for posts or the like.
  • Such openings can also be in the top Shell surface can be used. This makes it possible to build on the top surface of a partition or sliding wall, windbreaks, noise barriers, fences, but also posts for traffic signs, lighting equipment and much more.
  • the profile of the concrete elements of the separating device designed according to the invention is not mandatory for achieving the inventive advantages, but on the contrary, any profile shape suitable for the respective application can be used.
  • any profile shape suitable for the respective application can be used.
  • the prismatic cross section of the lying concrete element consists of a bottom is composed of the standing surface, laterally of a flat rectangle delimited at right angles to the standing surface and a trapezoid delimited by inclined running surfaces and an uppermost lateral surface running parallel to the standing surface.
  • Another already successfully used shape is characterized according to claim 18 in that the prismatic cross-section of the lying concrete element above the trapezoid has a further high trapezoid delimited by steeply inclined lateral surfaces and the uppermost lateral surface and corresponds essentially to that of the "New Jersey" profile.
  • the further development according to claim 19 is particularly advantageous, which is characterized in that that the prism cross-section of the lying concrete element is asymmetrical to the solder center line on the standing surface and is delimited in a straight line on the side facing away from the traffic by a lateral or steeply inclined lateral surface.
  • the separating device can be varied as required.
  • the concrete elements can be made small or comparatively short or large and comparatively heavy, depending on which task the separating device has to fulfill and which loads it is exposed to.
  • the lower slot with the double-conical connecting bar is generally the form which is advantageous for heavy and large configurations
  • the upper slot with the upper connecting bar is generally advantageous for light versions, although this rule does not rule out exceptions, that require conflicting solutions.
  • a size which, according to at least previous knowledge, is the most suitable for the use of partitions and sliding walls is characterized in that concrete elements with a "New Jersey" profile have a footprint of approximately 0.6 m and a height of approximately 8 .0 m and a length of approx. 3.0 m.
  • Fig. 1 shows a concrete element 2 in front view.
  • the concrete element 2 shown is adapted approximately to the "New Jersey" profile. It has the shape of a prism, which is arranged lying in the separating device 1 (see FIG. 20).
  • the cross section of the lying concrete element 2 consists of a lower flat rectangle 3 and an overlying trapezium 4, which is followed by a relatively slim trapezoid 5.
  • the concrete element can consist of high-density concrete and internal steel reinforcements, not shown.
  • the concrete element 2 as the lower surface of the prism, has a standing surface 6 and an uppermost boundary surface 7.
  • the concrete elements 2 have end faces 8 which run in the wine cell from 45 ° to a longitudinal median plane 9. With these end faces 8, the concrete elements 2 can be arranged close together to the separating device 1. They have surfaces or pressure contact at least in some areas and overlap one another at the ends in such a way that no gaps or gaps arise between two concrete elements 2.
  • FIG. 2 shows an embodiment of a separating device in the median of directional lanes.
  • the direction of traffic is shown in FIG. 2 by the arrow V.
  • This arrangement and configuration has the effect that that corner, of the concrete element 2, which opposes the traffic direction V on the side exposed to traffic has an angle of 135 °.
  • This has the advantage that even if two concrete elements 2 have been displaced in relation to one another and the front corner exposed to traffic is exposed, an obtuse angle is created, the legs of which serve as sliding and sliding surfaces. In this way, an impacting vehicle cannot be subject to the effects of a frontal impact, but is gliding away over the obtuse-angled surfaces.
  • the separating device 1 can be made from concrete elements 2 without the need for an additional mutual mechanical connection for normal cases, because a tendency toward impact caused by impact force Displacement of an individual concrete element communicates itself after overcoming the security against displacement by the friction of the standing surface 6 with the subsurface of the adjacent end surface 8, so that the adjacent concrete element 2 absorbs the rest of the impact force not absorbed by the affected concrete element 2. Under normal conditions, therefore, only negligibly small shifts are possible. Even vehicles hitting at right angles to the length of the concrete elements do not lead to displacements of the concrete elements 2; because in this case too, the inclined end faces 8 transmit those residues of the impact force which they cannot absorb through their own security against displacement to the neighboring concrete element or elements.
  • wedge-shaped gaps 10 can be filled with removable casting compounds in temporarily created separating devices 1, and permanent casting compounds can be inserted in the case of permanent designs.
  • the end face 8 and optionally or also exclusively the standing area 6 according to FIG. 3 can be equipped with mushroom-shaped knobs 11 made of elastic material anchored in the concrete element.
  • the knobs press into the ground and increase the security against displacement.
  • the knobs can be in a gap with respect to one another, so that they interlock to a certain extent and counteract relative displacements on mutually bordering end walls 8.
  • the surface of the concrete element 2 is recessed in the area of the end face 8 and is generously rounded at the corners and that the concrete element is supplemented by elastic material 12 to the original shape.
  • This material can be firmly adhered to the concrete element by appropriate measures and can also be seen in the lower area of FIG. 3 also have knobs 13 on its surface.
  • End faces, adjacent jacket surfaces and the base 6 can be equipped in this way. Resiliently flexible materials press into rough surfaces or adapt to them, thus increasing the resistance to displacement against impact forces.
  • the generous rounding on the end faces protects the concrete elements from unfavorable loads.
  • the resilient material is able to absorb thermal expansion.
  • the partially reproduced concrete element 2 shown in FIG. 4 has a base 6 which is either equipped with elastic material 12 or mushroom-shaped knobs 11, but is otherwise smooth and even.
  • 5 are channel-shaped grooves 14, which are open at the bottom and are, for example, U-shaped in cross section at right angles to the longitudinal center plane 9, are incorporated into the base 6.
  • these grooves which are expediently placed so that there are uniform distances between the grooves 14 within the separating device 1, the displacement resistance of the concrete element increases with respect to the substrate, because the more or less flexible base material at least partially bulges into the grooves. With hard ground, however, the opposite is the case.
  • these grooves 14 have the considerable advantage that they enable cross-drainage through a separating device.
  • FIG. 6 shows the bottom view of the concrete element 2 according to FIG. 5.
  • a separating device 1 which is extremely resistant to impact forces can be created for normal cases, the safety of which consists in that the individual concrete elements themselves rest largely on their surface on the one hand and are securely displaceable on the other hand and on the other, they run at an angle of 45 ° End faces are in contact with each other and thus transfer unresorbed impact forces to neighboring elements.
  • FIGS. 7 to 9 For extreme cases, where these measures are not sufficient to ensure the security against displacement, the further developments according to FIGS. 7 to 9 are provided.
  • an upright, trapezoidal, lower slot 15 is worked into the standing area 6 of the concrete elements 2 symmetrically with respect to the longitudinal median plane 9, said slot being limited Height.
  • This slot opens into the end face 8 in the form of a comparatively narrow gap, while the broad trapezoid lies at a distance from the end face.
  • two adjoining concrete elements with lower slots 15 jointly delimit an approximately double-conical gap.
  • a lower connecting bar 16 is inserted into this gap.
  • the insertion is relatively simple in that the connecting bar 16, which is double-conical, is placed on the floor and the concrete element is placed over it when laying.
  • the lower connecting bolt 16 is advantageously designed as a reinforced concrete bolt, which has an inner steel reinforcement 17, but has a very narrow cross section 18 in the middle, which is designed to a certain extent as a predetermined breaking point.
  • a lower connecting bolt 16 can transmit tensile forces from concrete element 2 to concrete element 2 to a limited extent. It transmits thrust forces in the same way, in relation to transverse forces which are not transmitted via the end faces 8, but which tend to remove the end faces 8 from one another. If the concrete breaks under stress, the predetermined breaking point 18 takes effect. The concrete breaks and the steel reinforcement 17 maintains its strength. As a result, the concrete elements are only negligibly displaced relative to one another.
  • Another possibility of additionally mechanically connecting the concrete elements 2 to one another is to in turn guide the upper slots 19 in the uppermost lateral surface 7 near the end faces symmetrically to the longitudinal median plane 9, and to limit the upper slots 19 downward in the perpendicular direction.
  • These slots are expediently undercut, however, that is to say at their ends remote from the end faces spherical or angular in Cross section expanded. You can also bring the slots 19 to any existing transport thread 20. See Fig. 12.
  • upper connecting bolts 21 are inserted, which consist essentially of sheet metal, which is thickened at the ends by flanging or similar measures and which is covered on all sides by elastic material.
  • the lower connecting bar 16 as well as the upper connecting bar 21 can also be adapted to the situation of an arcuate separating device 1.
  • the lower connecting bars 16 can then already be prefabricated in the desired angular shape, the upper connecting bars 21 can be pre-bent or adapted in a suitable form on the laying point.
  • the upper connecting bolts 21 can also have devices which can be brought into engagement with the transport threads 20.
  • the separating device 15 shows a further application of the separating device 1, in which the concrete elements 2 are produced with a different profile, in such a way that they have a steeply inclined, flat boundary surface 22 facing away from the traffic.
  • This boundary surface 22 can also run perpendicular.
  • the concrete elements 2 produced in this way with an asymmetrical prism cross section are suitable as supporting and embankment walls. In this case too, they are at an angle End faces inclined from 45 ° to the longitudinal plumb plane not only transmit power but also cover effectively.
  • the end faces 8 can advantageously be glued to one another both in the case of the aforementioned designs and in this case in order to tightly close the gap between the adjoining end faces 8 and thus ensure additional power transmission.
  • dovetail-shaped conical recesses 23 at the height or in the area of the standing area 6,, the latter being open at the bottom. These recesses each run a certain length from the end face 8 in the direction of the concrete element and have an opening with a reduced cross section to the flat surface 22. Bridging bars 24 can be inserted into them, which are made of any material, concrete or the like, which can be angularly curved even when cornering, and which have the task of transmitting embankment pressures which are exerted locally on a concrete element 2 to the neighboring element.
  • the concrete element 2 of the separating device 1 designed according to the invention can not only be produced in different cross-sectional shapes according to FIG. 17 or 18, but it can also be advantageously equipped on its end face 8 or on other faces with retroreflective foils or plates or other security surfaces 25 , which contrast in color, reflect light, etc.
  • receiving holes can be provided in which posts 27, for example for traffic signs 28, warning bars 28 or, for example, posts (not shown) for noise protection or windbreak walls can be attached.
  • the concrete elements 2 shown can be manufactured in almost any dimensions, as far as the handling and the load capacity allow. You can have any profile, such as Figures 15, 17 and 18 show. In most applications, they can be set up without mechanical interlocking to the separating device.
