Definitions
- the invention relates to a concrete guide wall for traffic routes made of interconnectable individual elements, each individual element being provided on its two narrow end faces with a coupling rail with at least approximately C- or T-shaped cross section, each coupling rail directly or indirectly via an intermediate link with a coupling rail adjacent individual element is connectable, and wherein the two mutually opposite coupling rails of each individual element are connected to one another by a longitudinal element consisting of longitudinal bars and narrow sides.
- Such a concrete baffle has become known from the published patent application DE 39 42 838. It can be seen from this that a longitudinal element is fastened with its two narrow sides to the rear sides of the coupling rails of a single element. The narrow sides are formed by vertical round bars.
- This known concrete baffle can only have longitudinal tensile forces take up to a limited extent, when lateral forces occur, the coupling rails are deformed and the concrete guide wall in the area of the couplings is destroyed. This can also lead to the failure of the drawstring effect.
- the object of the invention is now to provide a concrete baffle which is more stable, is able to absorb higher longitudinal and transverse forces, and in which destruction in the coupling area can only occur under significantly higher loads.
- this object is achieved in that the narrow sides of the longitudinal element of a concrete guide wall consist of profile rails or the like with at least one longitudinal web and transverse flanges, i.e. I, C or T-shaped profile rails or the like, the profile rails or the like being used as reinforcing elements connected to the rear of the coupling rails or integrated into them and firmly connected to them.
- the coupling rails are reinforced in the longitudinal and transverse directions and it is particularly advantageously possible to force the longitudinal rods into the coupling rails via the longitudinally oriented webs of the profiled rails or the like.
- the profiled rails or the like of the narrow sides of the longitudinal elements have flanges which protrude laterally beyond the associated coupling rail, then an even higher stiffening and, in addition, a substantially improved anchoring of the coupling rail is achieved.
- the longitudinal bars of the longitudinal element are welded to the upper and lower end faces of the webs of the profile rails, the ends of the longitudinal bars being at a safety distance from the rear wall of the associated coupling rail and the profile rails and the associated coupling rails each without Longitudinal bars - are galvanized in one piece.
- the coupling rails can be galvanized cheaply and efficiently with the profile rails as relatively compact units without bulky longitudinal bars.
- the galvanized units can also be easily installed in the formwork of the concrete guide wall components. Now it is also easy to weld the longitudinal bars to the webs of the profile rails, whereby length tolerances of different formwork can be compensated for.
- the safety distance prevents the galvanizing of the rear wall of the coupling rail from being damaged as a result of the welding work, and at the same time causes the end of the (non-galvanized) longitudinal rod to have a concrete cover.
- the rails of the narrow sides of a longitudinal element are divided into two or more sections, with further longitudinal rods being arranged between the upper and lower longitudinal rods, the ends of which are integrated between the webs of the profiled rails which are spaced apart by approximately one longitudinal rod diameter and with the upper and lower sections are welded.
- coupling rails and intermediate members can be advantageously achieved if, in the case of coupling rails with an at least approximately C-shaped cross section and approximately trapezoidal supporting legs, an intermediate member with an approximately I-shaped cross-section can be inserted into the coupling rail, the transversely extending flanges of which on the supporting legs facing side are substantially adapted to the shape of the support leg, the contact between flanges and support leg is given near the flange ends or near the support leg approaches.
- the coupling rails lie on the narrow end faces of the individual elements in vertical slots which are open at the bottom but closed at the top are, the intermediate member can be inserted from below, or the individual elements can be pushed onto the intermediate member from above.
- This embodiment ensures that the coupling area is largely protected from the weather and de-icing salts from above. In addition, it is not possible for unauthorized persons to remove intermediate links.
- the invention also includes an embodiment in which to support the fulfillment of its task it can be provided that two interconnected adjacent individual elements are spaced apart by wedges, spacers or the like arranged in the joint between the two facing narrow end faces.
- the intermediate links or the connection of the two adjacent individual elements are brought into tension or in a force-locking manner Status.
- the wedges, spacers or the like are under pressure at the same time, so that the concrete guide wall consisting of the two individual elements - in the broader sense of many individual elements - is formed into a relatively rigid structure.
- the interaction of the individual elements and the behavior of the concrete guide wall composed of these individual elements is thus significantly improved with regard to the side impact of motor vehicles.
- the feared buckling or breaking through of a concrete baffle is largely prevented.
- wedges, spacers or the like are now stored in vertical, approximately groove-shaped recesses of the narrow end faces, they also act as a bolt against transverse forces, transverse blows or transverse movement of the individual elements against one another.
- the wedges or the like are designed as tubular pieces and are stored in vertical recesses which are conical and narrower towards the bottom, then advantageous handling and effect are predetermined.
- the pipe sections can be inserted from above into the recesses opposite one another and forming a vertical hole and driven in until the connection is force-locked. In the event of a collision with vehicles, kinetic energy can be dissipated through the deformation of the pipe sections without the individual elements being damaged or destroyed.
- the individual element 1 of a concrete guide wall according to the invention is shown in FIG. 1 as a transparent body with dashed outlines.
- Coupling rails 3 are arranged on the two narrow end faces 2, which have an at least approximately C-shaped cross section.
- a longitudinal element 5 is provided which connects the two coupling rails to one another.
- the longitudinal element consists of two longitudinal bars 5 'and its two narrow sides 6 are formed by profiled rails 7. These rails have a T-profile, the web 7 'of which is longitudinal and the two flanges 7''are transverse.
- the two coupling rails 3 lie in slots 9 and are drawn up to the apex of the individual element 1.
- Fig. 2 shows the left half of a longitudinal element 5 which is welded to a coupling rail 3.
- This longitudinal element has three longitudinal bars 5 '.
- the profile rails 7 are again T-shaped in this embodiment, the profile rail being divided into two sections.
- the upper and lower section are spaced from each other in the extent of the diameter of the longitudinal bars 5 '. This makes it possible to insert the middle longitudinal bar between the webs 7 'of the section rail sections and to weld them in at the top and bottom. So the force is applied absolutely centric.
- the upper and lower longitudinal bars are welded to the end faces of the webs 7 ', as a result of which the introduction of force also takes place in the main plane of the overall construction.
- a safety distance a is maintained between the ends of the longitudinal bars and the rear wall so as not to damage the galvanizing of the coupling rail during welding.
- the flanges 7 ′′ of the profile rails 7 project laterally over the coupling rail 3 and thus form a particularly secure stiffening in the transverse direction and, moreover, they ensure a solid anchoring of the built-in parts in the concrete.
- the profiled rails 7 are formed from approximately C-shaped pieces.
- the longitudinally aligned webs 7 ' lie horizontally, the transversely projecting flanges 7' 'encompassing the coupling rails 3 laterally, approximately like pliers.
- the profile rails 7 are welded to the coupling rail 3 and thus firmly connected to it.
- the longitudinal bars 5 ' are welded to the webs 7' of the profile rails 7.
- the coupling rail 3 shown in FIG. 4 with the profiled rail 7 welded to it as the narrow side of a longitudinal element together form a unit for the galvanizing. Since the longitudinal bars are not yet welded on, such units can be handled well and galvanized without any problems.
- the coupling rail is at least approximately C-shaped, whereas the profile rail has an I-shape.
- the web 7 ' is aligned longitudinally and lies in the Main level of the overall construction, the flanges 7 '' protrude laterally beyond the coupling rail.
- Fig. 5 shows an oblique view of a coupling rail 3, on the back of which a profile rail 7 is connected.
- the profile rail is integrated into the coupling rail.
- the flanges 7 '' of the profile rail form a unit with the rear wall of the coupling rail.
- the coupling rail and the profile rail forming a narrow side of a longitudinal element 5 can be made in one piece, e.g. extruded.
- Fig. 6 the right half of a longitudinal element 5 can be seen, the longitudinal rods 5 'are welded to the upper and lower end faces of a T-shaped profile rail 7.
- the welded-on coupling rail 3 has an I-shape and is suitable for being connected directly (without any further intermediate link) to the approximately C-shaped coupling rail of an adjacent individual element.
- the ends of the longitudinal bars 5 ' have a safety distance a from the rear of the coupling rail.
- Fig. 7 shows schematically in plan another way to design the narrow side of a longitudinal element.
- the profile rail 7 is given by two C-profiles, the webs of which are aligned longitudinally.
- a longitudinal bar 5 ' is welded between the webs.
- the profile rails are welded to the coupling rail 3.
- Fig. 8 shows a partial floor plan, in which a coupling rail 3 with an intermediate member inserted therein 4 is shown.
- the coupling rail has an approximately C-shaped cross section with approximately trapezoidal support legs 8, as are found in conventional anchor rails (for example, Halfen rails).
- the I-shaped intermediate member has flanges 4 'which are essentially adapted to the shape of the support legs on the side facing the support legs. Experience has shown that the points of contact are close to the flange ends or close to the support leg attachments.
- Fig. 9 the head of a single element 1 can be seen with the visible narrow end face 2.
- An approximately C-shaped coupling rail 3 lies in a vertical slot 9. The slot is open at the bottom, closed at the top.
- An approximately I-shaped intermediate member 4 can be inserted from below into the coupling rail or the individual element can be pushed onto a pre-assembled intermediate member from above.
- vertical, approximately trough-shaped recesses 11 can be seen in the end face, which are designed for the reception or storage of wedges 10 or the like.
- a wedge is a piece of pipe that is chamfered on the underside.
- the recesses can be conical in shape, being too narrow at the bottom.
