Guide barrier line

The invention relates to a steel barrier strip for delimiting lanes for motor vehicles.

In the scope of DE 38 27 030 C2, a guide rail line is known from guide rails that are detachably attached to one another in sections, in which each guide rail has a base body with a trapezoidal cross-section and inclined side walls, with a cover plate arranged between the upper longitudinal edges of the side walls and with support plates that are transversely connected to the lower longitudinal edges of the side walls and an upper guide rail with a C-shaped cross-section that is connected to the base body via vertical posts at a parallel distance.

The longitudinally successive guide rails are connected to one another by providing L-shaped lugs with holes at one end of the base body on the inside of the side walls and underside of the support plates, and by providing holes in the side walls and the support plates at the other end, whereby

Commerzbank AG Bochunj, Kcrjto'-No. 3864*782 (&Igr;_&Zgr;&iacgr;4304&thgr;£)36" · PosJbenk E's'V&Ji, Ktjntcj-No..7447-431 (BLZ 360 10043) ·*·*··· · .:·OS^JdNr:&Idigr;3&xgr; 12^1464Ji!.:.* |

after two guide rails have been joined together, they are screwed together. On the other hand, at one end of the guide rails there are C-shaped connecting bodies adapted to the inner contour with holes in the cover surfaces and the side surfaces, via which and holes at the other ends of the web plate and the side walls of the guide rail, the guide rails of successive guide rails are then screwed together.

This type of barrier line has proven itself to be particularly effective for demarcating lanes at construction sites. However, the assembly and disassembly of successive barriers is a hindrance and time-consuming, as this requires not only a large number of bolts, nuts and washers, but also the appropriate tools. In addition, this type of assembly and disassembly requires a lot of personnel.

EP 0 472 847 B1 discloses a guide rail line with guide rails made of base bodies with a trapezoidal cross-section and guide rails with a C-shaped cross-section, in which vertically extending plug pins are used to connect two successive guide rails. For this purpose, housing-like pins adapted to their cross-sections are inserted into one end of a base body or guide rail, which then engage in the free ends of a following guide rail. The plug pins penetrate recesses in the web plates of the guide rails, in the pins and in the cover plate of the base bodies. In addition, holes are provided at the ends of the support plates, via which, as well as adapted tabs, the adjacent support plates are screwed together. With such a connection, the assembly and disassembly of guide rails can be accelerated. However, practice has shown that jamming often occurs when the guide rails are put together and the plug pins are inserted.

This is especially true if the barriers have already been in use.

Finally, DE 199 43 229 A1 also makes it state of the art to be able to place guide rails with trapezoidal base bodies and C-shaped guide rails at an angle to one another by means of a corresponding V-shaped design of the front sides, so that a guide rail line made up of such loop-shaped guide rails can be used primarily to direct traffic flows from one lane to an adjacent lane. However, due to the lack of appropriate front-side support of adjacent guide rails, such a guide rail line is not suitable for safely ensuring the boundary between a lane and an adjacent lane when parallel to it.

The invention is based - based on the state of the art - on the object of creating a steel barrier line for delimiting lanes for motor vehicles, which can be quickly assembled and disassembled, requires only a small amount of personnel and can also be laid in a curve or loop shape if required.

According to the invention, the solution to this problem is seen in the features of claim 1.

A feature of the invention is that the front sides of each guide rail, when laid parallel to a lane, run in a vertical plane perpendicular to the longitudinal extension of the guide rail. It is also important that coupling housings adapted to the clear cross sections of the base body and the guide rail are inserted into the end sections of the base body and the guide rail and are fixed in the end sections by screw connections. The coupling housings at both ends of a guide rail thus form components of a guide rail. Coupling sleeves with vertically extending central receptacles are inserted into the front sides of the coupling housings in semi-cylindrical, vertically extending central receptacles.

cal axes. After the coupling housings have been installed in the guide rails, the axes extend in the vertical planes of the front sides of the guide rails. The 1st and 2nd coupling housings for a base body are designed in such a way that the 1st coupling housing has two coupling sleeves lying one above the other at a distance, while the 2nd coupling housing at the other end has a coupling sleeve located at the middle height, which fits exactly into the height range between the coupling sleeves of the 1st coupling housing. For the 3rd and 4th coupling housings, which are inserted and screwed into place at the end of the guide rail of a guide rail, only one coupling sleeve is provided in each case, in such a way that they lie one above the other when coupled, with the length of a coupling sleeve corresponding to approximately half the height of a 3rd or 4th coupling housing.

Furthermore, it is important within the scope of the invention that the front sides of the coupling housings are V-shaped next to the coupling sleeves and that in the side surfaces of the 1st and 2nd coupling housings assigned to the base body as well as in the side surfaces and in the cover surfaces of the 3rd and 4th coupling housings inserted into the guide rail, configurably adapted fixing holes and elongated holes are provided on fastening holes in the base body and in the guide rail.

The fastening and fixing holes allow the coupling housings to be precisely fixed in the base bodies and guide rails so that the coupling sleeves are perfectly aligned vertically one above the other.

If two guide rails are pushed together with their front sides touching, all coupling sleeves lie on top of each other with their longitudinal axes in the vertical plane of the guide rails' front sides. The V-shaped front sides of the coupling housings lie behind these vertical planes. All that is needed is to push a pin through the coupling sleeves from above to connect two guide rails together in a perfectly tension- and pressure-resistant manner. Since the coupling housings are thus inserted into the base bodies

or can be inserted into the guide rails and screwed to them so that the front sides of two consecutive guide rails lie exactly in front of each other, a secure flat support is guaranteed.

If it is necessary to transfer the flow of traffic from one lane to a parallel lane, only the number of guide rails that are required for a loop-shaped installation of the guide rail line needs to be removed from the guide rail line. To do this, the screw connections are loosened and after pulling the plug pins out of the coupling sleeves, the coupling housings are pushed into the base bodies or guide rails so that the guide rails can now be easily removed transversely from the guide rail line. Then, for loop-shaped installation, guide rails are inserted, which are also V-shaped on the front side. The coupling housings are then pulled out of the base bodies or guide rails so far that, depending on their position in the loop, they are now directly in front of each other together with the front sides of the guide rails and the plug pins can be easily inserted into the coupling sleeves. Thanks to the elongated holes in the coupling housings, these can then be firmly screwed back onto the base bodies and the guide rails.

In this case, it is also ensured that the front ends of the guide rails abut perfectly against each other even when laid in a loop. The testing requirements of the Federal Highway Research Institute are thus perfectly met. There are no unacceptable gaps.

The design of the guide rails and the coupling housing according to the invention therefore allows for easy, simple and quick assembly of a guide rail line and equally simple disassembly. In addition, a problem-free and also quick conversion of sections

a straight-line guide rail line can be converted into a loop-shaped guide rail line.

A further advantage of the design according to the invention is that even older guide rails with base bodies with a trapezoidal cross-section and with upper C-shaped guide rails connected by vertical posts at a parallel distance can be easily converted. Since hand holes are already provided at the end of the cover and web plates of the base bodies or guide rails in the state-of-the-art guide rails for handling the screw connections, all that is needed to convert the known guide rails is to make semicircular recesses extending from the front sides in order to bring them into a vertical alignment with the coupling sleeves.

According to claim 2, it is advantageous if the coupling housings are closed on the circumference and on the V-shaped front sides. The coupling housings are conveniently manufactured by bending a sheet of metal and punching and welding. The base bodies and guide rails of the guide rails are also produced by simple bending, if necessary in a continuous process on appropriate forming machines.

According to the features of claim 3, the plug pins are made of pipe sections with head-side discs that carry assembly handles. The discs have a larger diameter than the pipe sections, so that when the plug pins are inserted into the coupling sleeves, they lie on the web surfaces of the guide rails.

The invention is explained in more detail below with reference to embodiments shown in the drawings.

Figure 6 is a plan view of the joint area of two guide rails angled towards each other.

In Figure 1, reference numeral 1 designates a steel guide rail line consisting of guide rails 2 which are detachably attached to one another in sections.

Each guide rail 2 has, as can be seen when looking at Figures 1, 2 and 5 together, a base body 3 with a trapezoidal cross-section and inclined side walls 4, a cover plate 6 arranged between the upper longitudinal edges 5 of the side walls 4 and support plates 8 transversely connected to the lower longitudinal edges 7 of the side walls 4 and an upper guide rail 10 with a C-shaped cross-section connected to the base body 3 via vertical posts 9 at a parallel distance. The base body 3 and the guide rail 10 are formed from steel sheets by forming. The vertical posts 9 have a sigma-shaped cross-section.

The end faces 11, 12 of the base body 3 and of the guide rail 10 extend at each end of a guide rail 2 in a vertical plane VE which extends perpendicular to the longitudinal direction of the guide rail 2 (Figure 2).

Five fastening holes 13 are provided at the end of the side walls 4 of the base body 3 (Figures 1 to 3). Furthermore, Figures 1 to 3 show that fastening holes 16, 17 are also provided in the side plates 14 and in the web plate 15 of each guide beam 10.

The connection of two guide rails 2 is made via coupling housings 18-21 and plug pins 22 provided at the ends of the base body 3 and the guide rails 10 (Figures 1 to 4).

The 1st and 2nd coupling housings 18 and 19 for the base bodies 3 are adapted to their clear cross-section (see in particular Figure 4). In the side surfaces 23 of the 1st and 2nd coupling housings 18, 19 there are five fixing holes 24, which are configured to match the fastening holes 13 in the side walls 4 of the base bodies 3. It can also be seen that elongated holes 25 are provided in the side surfaces 23 of the 1st and 2nd coupling housings 18, 19, each offset in the longitudinal direction to the fixing holes 24.

Semi-cylindrical receptacles 27 are provided in the middle of the V-shaped front sides 26 of the coupling housings 18, 19, which face each other (Figure 4). The front sides 26 next to the receptacles 27 are closed. The receptacles 27 serve to secure coupling sleeves 28-30. While the first coupling housing 18 has two coupling sleeves 28, 29 spaced apart from one another, only one coupling sleeve 30 is inserted into the receptacle 27 of the second coupling housing 19. This coupling sleeve 30 is located in the height range between the two coupling sleeves 28, 29 of the first coupling housing 18.

Corresponding to the receptacles 27, semicircular recesses 44 are provided in the web plates 15 of the guide rails 10 and in the cover plates 6 of the base body, starting from the end faces 12, 11 (Figure 3).

The 3rd and 4th coupling housings 20, 21 are adapted to the clear cross-section of the C-shaped guide rails 10 (Figure 4). They have fixing holes 33, 34 in the side surfaces 31 and in the cover surfaces 32, which are configured to the fastening holes 16, 17 at the end of the guide rails 10. It can also be seen that corresponding elongated holes 35, 36 are provided in the side surfaces 31 and in the cover surfaces 32, offset from the fixing holes 33, 34.

The V-shaped end faces 37 of the 3rd and 4th coupling housings 20, 21 also have central semi-cylindrical receptacles 27 in which coupling sleeves 38, 39 are fixed. It can be seen that in the 3rd coupling housing 20 the coupling sleeve 38 is offset upwards towards the cover surface 32, while in the 4th coupling housing 21 the coupling sleeve 39 is offset downwards. The V-shaped end faces 37 next to the receptacles 27 are closed.

The coupling housings 18-21 are inserted into the base bodies 3 or the guide rails 10 during the manufacture of the guide rails 2 and are firmly screwed to them via the fastening holes 13, 16, 17 and fixing holes 24, 33, 34 (Figure 2). The assignment is such that the axes running through the coupling sleeves 28-30, 38, 39 run in the vertical planes VE of the end faces 11, 12 of the base bodies 3 and the guide rails 10.

When installing a guide rail line 1 (Figure 2), it is only necessary to push a new guide rail 2 in the longitudinal direction towards a previously installed guide rail 2 until the end faces 11, 12 touch. After this, a plug pin 22 only needs to be pushed from above through all the coupling sleeves 38, 39, 29, 30, 28 aligned vertically one above the other in order to connect two guide rails 2 together perfectly.

Such a plug pin 22 consists of a tube section 40 and a head-side disk 41 of larger diameter, which carries a handle 42 (Figure 4).

After assembly, the configuration is as shown in Figure 1.

In addition to Figures 1 and 2, it should be noted that 2 water passage channels 43 are formed in the lower height area of the guide sills.

In order to redesign the guide rail line 1 of Figure 1 in a loop-like manner in certain areas so that a flow of traffic can be transferred from one lane to a parallel lane, the plug pins 22 of, for example, four consecutive guide rails 2 are first pulled out of the coupling sleeves 28-30, 38, 39. Then only the screw connections of the coupling housings 18-21 with the base bodies 3 and the guide rails 10 need to be loosened in order to then push the coupling housings 18-21 into the base bodies 3 and the guide rails 10 so that nothing protrudes beyond the front sides 11, 12. Now, to create the loop-like configuration of a guide rail line 1, two guide rails 2 can be removed transversely to the side or upwards from the guide rail line 1.

In place of these guide rails 2 with end faces 11, 12 running perpendicular to their longitudinal extension, guide rails 2a are now inserted between two longitudinal sections of the guide rail line 1 that are parallel to one another, as shown in Figure 6, which have V-shaped end faces 11a, 12a.

The newly inserted guide rails 2a with V-shaped front sides 11a, 12a also contain coupling housings 18-21, particularly as shown in Figures 3 and 4.

Then it is only necessary to move these coupling housings 18-21 in the longitudinal direction of the base body 3a and the guide rails 10a of the guide rails 2a until their front sides 11a, 12a abut one another in the miter area and thus the coupling sleeves 28-30, 38, 39 are vertically aligned one above the other. Then plug pins 22 are inserted into the coupling areas with the coupling sleeves 28-30, 38, 39 and then the coupling housings 18-21 are screwed to the base bodies 3a and the guide rails 10a via the elongated holes 25, 35, 36.

In this way, as indicated in Figure 6, even when a guide rail line 1 is laid in a loop-like manner in some areas, two guide rails 2a can be supported on one another perfectly via one of the end faces 11a, 12a and via one of the end faces 26, 37 of the coupling housings 18-21.
