Description

The invention relates to a transportable barrier for a crowd barrier according to the features in the preamble of claim 1.

Crowds are formed from a series of individual barriers, which are usually coupled together by connectors. Such jostling barriers are also referred to as police grid. These barriers include an upstanding part, hereinafter referred to uniformly as a safety gate, rigidly connected to a floor panel or floor assembly. People stand on the floorboards and at the same time can push or pull on an upper handle of the barrier without the barrier falling over. Due to the very long lever arm of the barrier against the bottom plate, occur in the transition between barrier and floor panel high Bending moments on. To intercept these moments, are located on the side facing away from the bottom plate a plurality of bottom-side boom. The safety gate is then located between the one-side protruding part of the tubular boom and the floor assembly, so that the Gedrängesperre can not fall over. The boom is welded to a spar, in particular to a pipe in the transition region between the base assembly and the barrier. To facilitate welding, the end of the tubular cantilever is compressed so that the tube profile is flattened and thereby can be butt welded to the tube in the transition region between the barrier grid and bottom assembly via a substantially straight weld. These welds are loaded by Biegewechselbeanspruchungen. If a person who stands on the bottom plate and presses against the upper handle rail of Absperrgitters, the boom is supported with its projecting end on the ground. In the opposite direction of force, that is, when people who stand on the base plate pull on the handle bar, there is no such support. By repeatedly bending back and forth, it may be possible that the weld breaks and the safety gate can be pressed flat onto the floor assembly. As a result, dangerous situations may arise for all involved in the area of such a blockage. It will be in the DE 20 2014 105 757 U1 describes a transportable Gedrängesperre which has displaceable, ie extendable boom, which are guided in a hollow profile. The booms are highly resilient. However, there are also applications in which it does not depend on the variability of extendable boom and resilient and almost very light barriers are desired. In the NL 67 750 C a portable barrier is described. This has cantilevers, which consist of a lower and an upper leg, which are connected by a bend.

The invention has for its object to provide such a rigid barrier for a crowd barrier, which withstand higher loads with the same or lower weight and has a higher fatigue strength.
This object is achieved with a transportable barrier with the features of claim 1.
Advantageous developments of the invention are the subject of the dependent claims.

There is proposed a transportable barrier for a ratchet barrier, the barrier having a horizontal floor assembly and a barrier grid disposed on a first longitudinal side of the floor assembly, and wherein the barrier has at least one boom adjoining said longitudinal side around the floor Additionally support the safety gate on the side facing away from the floor assembly. The at least one boom has a lower leg. This lower leg lies wholly or partially on the ground. The barrier has the shape of an upside-down letter T in cross-section, with the lower leg on one side and the bottom assembly on the other side forming the transverse part of the letter T, and the safety gate forming the vertical part.

According to the invention, it is provided that a lower leg of the at least one arm extends beyond the longitudinal side of the bottom subassembly in the same material as one piece into the bottom subassembly. This means that the boom is located not only on one side of the shut-off grid, but on both sides of the shut-off grid. Therefore, the substantially horizontal lower leg does not terminate upon reaching the bottom assembly, but penetrates into this or is continued on the other side of the Absperrgitters. Preferably, this lower leg of the at least one arm extends through a lower frame part, which is arranged alongside in the transition between the floor assembly and the safety gate. The at least one boom passes through this frame part in the same material as one piece. It is essential to the invention that in the transition region of this frame part there are no longitudinal joints of the cantilever itself and, in particular, no welded connections to the longitudinal connection of the at least one cantilever itself. The at least one boom is a continuous component to which the frame part is welded and not vice versa. That is, not the boom is welded to the frame part, but the frame is interrupted, so that the boom can material uniformly one piece, ie without joints, enforce. The lower frame part is thereby divided into several frame sections. These frame sections are preferably only indirectly connected to one another via the arms.

The arrangement according to the invention has decisive advantages in terms of fatigue strength. On the one hand, an improvement in fatigue strength already results from the fact that the at least one continuous boom does not end in a region in which the bending loads are highest. In addition, in this area, no weakening of the at least one boom by compressing the ends are performed in order to better weld the ends with other profiles can. As a result, there is also the weld influence zone, which due to thermal influences regularly leads to a structural change and usually to a weakening of material, outside of the range in which attack the maximum bending moments. The bending stiffness of the transportable barrier is thus almost exclusively determined by the area moment of inertia, i. H. the cross-sectional contour of the at least one cantilever determined. The bending stiffness is no longer dependent on the design and execution of the welds. As a result, in particular human factors that always play a role in welding, turned off. Overall, barriers of higher quality and higher quality standards can be produced.

Another advantage is that the barriers as a whole can be made lighter. The flexural rigidity is, as explained above, significantly determined by the cross-sectional contour of the at least one arm. All other components that are connected to the at least one boom, can be correspondingly less rigid and thus made lighter.

The advantages according to the invention always come into play when the lower leg does not terminate at the longitudinal side of the bottom module but extends beyond it. This does not mean that the lower tavern inevitably has to extend completely through the lower frame part in the sense that it completely interrupts this or completely or partially penetrates it. The advantages according to the invention also arise when the lower leg overlaps or engages under a lower frame part alongside the bottom module. By this is meant that the leg is passed over the top of the frame part or passed below it, without that the frame part itself changes its cross-section or its profile shape. The two profiles, ie the leg and the lower frame part are guided to one another, as it were, and connected to one another in the intersection area. In the context of the invention, intermediate forms are also possible in which the cross-sectional geometries of the lower leg and of the frame part do not penetrate completely, but only partially. For example, the lower frame part may have a recess in the form of a notch or dent, through which the lower leg is guided. Such a notch or indentation can be arranged on top or bottom of the lower frame part, depending on which side of the lower leg is to be passed. If the lower frame member is a tubular member, this may preferably be so far compressed in the crossing region with the leg that results in a passage that is inexpensive to produce and relatively large contact surfaces with the lower leg of the boom allows and thus sufficient possibilities connect two components together, in particular to weld.

In the event that it is preferred to make the lower frame part substantially straight and continuous, while the boom is in any case preferably a multiply bent component, it can also be provided in one embodiment of the invention that the lower leg of the Jib in the crossing region with the lower frame member has a bend to avoid the lower frame member. This bending leads, in particular, to the fact that the lower limb does not extend completely parallel to the ground or ground, but at least in the crossing region allows the lower frame component to run below the lower limb. The lower leg can be bent several times for this purpose, so that as much of its length as possible runs parallel to the ground in order to achieve the best possible support. However, it is also sufficient for stability if the jib touches the ground at a point as far as possible from the safety gate, in order to ensure the stability of the barrier.

It is considered advantageous if the lower leg of the at least one arm extends integrally in one piece, ie, without interruption, extending not only through the lower frame part but also as far as a second longitudinal side of the floor assembly. The background is that not only that Frame part is to be penetrated in the transition between floor assembly and safety gate, but that the lower leg should be much longer and is connected with its free end to the other longitudinal side. As a result, there are no interruptions in the area of the lower leg of the boom.

Also, the upper leg of the at least one boom is interruption free, d. H. designed consistently. For this purpose, the upper leg of the at least one arm can enforce the entire safety gate up to an upper handle bolt of Absperrgitters. For the purposes of the invention include the upper leg those longitudinal sections of the boom, which do not belong to the lower, bottom-side leg. If a middle leg is mentioned, this functionally no longer belongs to the lower leg, but to the upwardly rising upper leg.

The lower leg and the upper leg of the at least one arm are integrally formed integrally with each other material. This means that the entire boom is made up of a single component. In particular, it is a bent tube profile.

With regard to the barrier, the lower frame part, which is arranged alongside in the transition between the base assembly and the barrier, belonging to the frame of Absperrgitters. This frame also has at least one horizontally extending central latch and a top handle bar. The handle bar, the at least one horizontally extending middle latch and the lower frame part can be connected to each other at the edge via posts. In the central region of the shut-off grid, the at least one upper leg of the at least one arm fulfills the function of a post. The upper leg of the jib has a vertical section (jamb) which runs in the plane of the shut-off grille and an angled portion projecting out of the plane of the shut-off grille, which is approximately at 45 ° to the ground or ground assembly and at the same time at 45 °. Angle to the barrier extends, so that this part of the upper leg to support the Absperrgitters obliquely downwards and is connected via a bend with the horizontal lower leg of the boom.

Such a barrier may have a width of about two meters, wherein it is sufficient at this width to arrange two identically formed boom in a parallel distance from each other. These parallel spaced beams then extend continuously from the top handle bar of the gate to the second longitudinal side of the tray assembly. For wider barriers, more than two extension arms can be provided if required.

The ends of the at least one arm preferably have end-side infillings, which are adapted to the cross-section of the handle bolt and / or a longitudinal frame part. Although it is possible to flatten straight ends of a cantilever and weld the flattened ends over longitudinal seams that extend in the axial direction of the frame part or handle bar, but these are weak points. Infills allow in addition to the cohesive connection (welding) in addition a positive connection between the ends of the boom and the adjacent components. The contact area between the ends of a boom and the handle bars or other frame parts is no longer straight, but runs three-dimensional curved, with such contours can be welded relatively easily. Even with a failure of the weld, it is still possible to transfer loads as long as the fit between the infill and the adjacent components exists.

The base assembly and the barrier are preferably welded structures, wherein the base assembly and the barrier are each welded to the material uniformly from its one end to its other ends continuous boom. Again, it is important that not the least boom is interrupted, but that there may be interruptions in the area of the floor assembly and the Absperrgitters. Therefore, the frame parts of the base assembly or the Absperrgitters are where the jib run, at least interrupted when the boom passes through these frame parts. In the context of the invention is of course also possible to attach the boom so that z. B. the bars need not be interrupted, but that there are crossing areas where bars and jibs are passed to each other, but still connected to each other in these areas.

Since the main load of a horizontally acting force is carried by the at least one cantilever, it is possible to make frame members, latches and posts correspondingly weaker. Therefore, the wall thickness of the frame members, bars and / or posts may be smaller than the wall thickness of the at least one cantilever. Preferably, it is tube profiles that have the same outer diameter and differ only in the wall thickness.

The shut-off grid is preferably surrounded by a circulating safety gate frame, which is preferably pierced only by the at least one boom. If a material unitary one-piece production of a revolving fence frame is not possible, it is of course within the scope of the invention also possible to individually produce the posts of Absperrgitterrahmens and then add to the handle bar, in particular to weld.

Preferably, the bottom assembly has a bottom assembly frame that holds a bottom plate. The term "base plate" is to be understood as representative of all plate-shaped components on which people can stand. It may therefore also be grates, grids or an arrangement of struts. Checker plates with individual water drainage openings are also possible, as are plastic planking or composite materials suitable for the intended use.

It is considered advantageous if the bottom plate does not project upwardly above the bottom assembly frame. This is particularly possible with flat floor panels when fitted to a floor assembly frame formed from tubular profiles. So that the floorboards do not fall through the floor assembly frame, the floorboards are slightly larger than the shelves bounded by the frame, but not so large as to protrude above the top of the pipes. They are attached to a certain extent in the region of the obliquely upwardly facing surfaces of the tubes. In the case of a metallic floor grid, the fastening can be done, for example, by spot welding.

In the context of the invention, the term "base assembly frame" refers to that region which delimits the base assembly with respect to the outer edge. Functionally considered, the lower legs of the arms contribute to the stiffening of the whole floor assembly, and in particular also to support the floor assembly frame. In particular, together with the horizontal leg of the boom, several floor areas of the floor assembly are limited. An average of these floor areas may be larger than a marginal floor area. In such a middle floor area, which is bounded by two lower legs, a support strut can be arranged below the floor panel. This preferably runs from the first longitudinal side to the second longitudinal side of the bottom module. On this support strut, the bottom plate can be supported. This relieves the connection of the bottom plate with the bottom assembly frame or with the at least one boom to which the bottom plate can be attached as well as to the frame. Preferably, a lower leg of the at least one cantilever is level with the upper edge of the floor assembly frame with respect to its upper edge so that there are no tripping hazards.

The base assembly is preferably formed trapezoidal so that adjacent barriers can be angled to each other in order to train corners in a Gedrängesperrefront or to curves, z. B. to follow from roads.

To connect adjacent Gedrängesperren are on lateral posts of Absperrgitterrahmens on the one hand upper and lower tabs and on the other hand matching, downwardly facing upper and lower hooks arranged for connection with hooks and tabs other barriers. The hooks are different lengths. Preferably, the lower hook is 10-30 mm longer than the upper hook, so when connecting adjacent barriers, first the longer lower hook must be inserted into a tab. Only then can the other hook be inserted into the tab. This simplifies assembly compared to the same length hooks.

The hooks can be straight. Preferably, at least one hook is bent on the end side, so that only in an angle deviating from 180 ° angle can be connected to each other. As a result, unlocking in aligned arrangements of the barrier is no longer possible. The transportable barriers are interlocked with each other and form a closed impeding barrier. To improve the attachment of the hooks, especially in posts with thin wall thicknesses, the hooks may have a mounting base that passes through openings in the posts and is welded to the edges of said openings.

The transportable barrier according to the invention is preferably a welded construction consisting of galvanized steel tubes. All pipes have drainage holes for the purpose of hot dip galvanizing to allow perfect internal and external galvanizing. Such a transportable barrier is significantly lighter than barriers of comparable designs but at the same time more stable and durable.

The barrier 1 in FIG. 1 shows a substantially L-shaped configuration with a horizontal floor assembly 2 and with a perpendicular thereto arranged shut-off grid 3 and a boom 4 of the double exists, as shown in FIGS FIGS. 2 and 3 can be seen. Such a transportable barrier 1 can be connected to other, identical barriers to a longer crowd barrier with each other.

The barrier 3 has a height of 1100 mm in this embodiment. It is without edge hooks 5, 6 and corresponding tabs 7, 8 on the other side of the Absperrgitters 3 2000 mm wide. Based on FIGS. 1 to 3 It can be seen that the transportable barrier has a load-bearing, frame-like structure. There are several frame components for this purpose. The safety gate 9 is composed of an upper-side handle bar 10 and a below the handle bolt 10 parallel spaced, horizontally arranged bolt 11 and posts 13, 14 together, which the horizontal frame member 12, the horizontally extending latch 11 and the horizontally extending handle latch 10 together connect. While the upper-side handle bolt 10 is a one-piece component and is formed by bending a pipe profile of the same material and integral with the post 13, 14 and the lower frame member 12, the horizontally extending middle bar 11 is broken by the arms 4, 15. The arms 4, 15 are arranged at a horizontal distance of about 900 mm from each other. At least one area above the central bolt 11 may be closed with a flat filling element, in particular a sheet 42, preferably a perforated sheet or a grid. A region below the middle bar 11 can also be closed with a flat filling element, wherein openings for the arms 4, 15 can remain in the lower area in order to be able to maintain the stacking density.

The booms 4, 15 extend not only uniform material through the vertical part of the Absperrgitters 3 above the central bolt 11, but are below the bolt 11 in the further course in each case by 45 ° with respect to the bottom assembly 2 and the blocking grid 3 angled, as based on the middle Thigh 16 in FIG. 1 can be seen. The middle leg 16 is deflected by 135 ° over a further bend 37, which integrally connects the same material in the lower Leg 18 which continues through the lower frame member 12 ( FIG. 3 ). As a result, the arms 4, 15 extend with their lower legs 17, 18 through the first longitudinal side 19 of the base assembly 2 through to a second, parallel longitudinal side 20 of the trapezoidal base assembly 2.

Based on FIGS. 2 and 3 it can be seen that the arms 4, 15 are not interrupted at any point. Only the latch 11 and the lower frame part 12 are interrupted and laterally welded to the boom 4, 15. FIG. 2 shows that the lower frame part 12 is divided into three frame sections. The two outer frame portions 32, 33 are made by bending against the posts 13, 14. The middle frame section 34 extends in alignment with the two outer frame sections 32, 33. The middle frame section 34 is welded laterally to the respective arms 4, 15 and connected indirectly to the further frame sections 33, 34 via the arms 4, 15. The ends 21, 22 of the arms 4, 15 have infills 30, 31, which can be seen from the course of the ends 21, 22 ( Fig. 4 ). To a certain extent, the ends 21, 22 embrace a longitudinal frame part 23 of the floor assembly or the handle bolt 10.

The almost completely encircling fencing frame 9 may have a smaller wall thickness for the same outer diameter than the arms 4, 15. The same applies to a floor assembly frame 24, as it is in FIG. 3 can be seen. This bottom assembly frame 24 is configured substantially trapezoidal, wherein the trapezoidal part is limited in its broader base by the lower frame part 12 of the Absperrgitters 3. In between there are bottom plates 25, 26, 27. The bottom assembly 2 is therefore closed. A horizontal support strut 28 is located below the middle floor plate 27 to support it against deflection. FIG. 1 FIG. 5 shows that the floor panels 25, 26, 27 are secured so that they do not project upwardly above the floor assembly frame 24.

Based on FIG. 2 it can be seen that the hooks 5, 6 have different lengths. The upper hook 5 is also bent and protrudes from the central longitudinal plane of the Absperrgitters 3 ( FIGS. 1 and 3 ). If a tab 7 of an adjacent transportable barrier 1 is oriented as the hook 5 is bent, can the barriers 1 are hooked into each other and then locked by aligning in a direction that does not correspond to the orientation of the bent end of the hook, against each other so that the hook 5 can not be pulled up out of the tab 5. The different length tabs 5, 6 have the advantage that when mounting first the lower hook 6 engages in the tab 8 and only then after the engagement of the lower hook 6 of the upper hook 5 with the tab 7 of the adjacent barrier 1 engages , This facilitates the assembly.

FIG. 4 shows the boom 4 of FIGS. 1 to 3 , The boom 4 is a material unitarily manufactured in one piece continuous pipe without cross-connection points. The lower leg 17 extends parallel to the background, not shown. The middle leg 16 is bent by 135 ° relative to the lower leg 17 (bend 37). At the top adjoins the middle leg 16 a perpendicular to the lower leg 17 standing upper leg 29, which is in the installed position in the plane of the Absperrgitters 3, such as FIG. 1 shows. It can be seen that concave infills 30, 31 are formed both at the upper end 22 and at the lower end 21 of the cantilever 4. The contour of the infills 30, 31 is adapted to the outer cross-sectional contour of the adjacent components, that is with respect to the upper infill 30 to the underside of the handle 10 ( FIG. 2 ) and with respect to the other infill 31 at the lower end 21 to the longitudinal frame part 23. As a result, the contact area between the components is increased in each case and also reaches a form fit respectively transverse to the longitudinal axis of the boom 4.

While in the embodiment of the FIGS. 1 to 3 the lower frame part 12 has been penetrated by the two arms 4, 15 and thereby completely interrupted, the variants shown below show arms 4, which are deviatingly configured, wherein the already introduced reference numbers have been retained for substantially the same components. The boom 4 of FIG. 5 is different from the one of FIGS. 1 to 3 in that it does not penetrate the lower frame part 12. Its lower leg 17 is guided over the lower frame part 12. From the sectional view of FIG. 6 It can be seen that the lower frame part 12 does not have to be interrupted thereby, as well as the lower leg 17 does not have to be interrupted. The lower leg 17 has been angled only twice for the implementation of the lower frame part 12. A first bend 35 is located above the lower frame part 12. In the direction of the rear end 21, another, opposite bend 36 follows, so that a large part of the lower leg 17 extends within the floor assembly 2, not shown. The region of the lower leg 17, which is arranged on the side facing away from the bottom assembly, is continued by the first bend 25 straight to a bend 37, which forms the most protruding part of the boom 4. The bend 37 is made at an angle of about 135 °, so that the middle leg 16 at an angle of 45 ° to a horizontal plane has rising upward and merges into the vertical, upper leg 29. As a result, a front leg portion 38 between the bend 37 and the lower frame member 12 is arranged slightly obliquely with respect to the ground plane extending.

In a manner not shown may be similar to the bend 36, a second such angled portion may be provided in the leg portion 38, so that the lower leg 17 extends parallel to the ground.

FIG. 7 shows an embodiment in which also an angled portion 35 in the region of a lower frame part 12 is arranged, which is passed below the lower leg 17. From the sectional view of FIG. 8 It is clear that the lower frame part, which is designed as a tube profile, is compressed in the region of the intersection with the lower leg 17 and forms a trough for receiving the lower leg 17. For this purpose, the lower leg is angled several times. In addition to the bend 35, on both sides of the lower frame part 12, there are further opposing bends 36, 39, so that the lower leg 17 runs horizontally over almost its entire length and thus runs parallel to the background, which is not shown in detail. The middle leg 16 and the upper leg 29 extend in the same way as in all other embodiments of arms 4 explained above.

FIG. 9 shows a further variant of a boom 4. Similar to the embodiment of FIG. 5 the lower frame part 12 is below the lower one Leg 17 passed. The leg portion 38 lying to the bend 37 is provided adjacent the lower frame part 12 with an angled portion 39, so that this leg portion 38 extends predominantly parallel to the background, not shown, ie horizontally. In contrast to the embodiment of FIG. 5 Although the other leg portion 40 of the lower leg 17 also extends horizontally, but at a distance from the ground, because its rear end 21 ends above the longitudinal side frame part 23. There is therefore a parallel offset between the leg portion 37 leading to the bend and the bottom group side leg portion 40. The lower end 21 of the lower leg 17 is also provided with a chamfer 41 which is intended to avoid sharp-edged stumbling traps. FIG. 10 points in the direction of arrow X in FIG. 9 the crossing region between the lower frame part 12 and the lower leg 17. The lower leg 17 extends as in all embodiments above the lower frame part 12. As in the embodiments of Figures 5 and 7 is also according to the variant FIG. 9 an angled portion 35 in the lower leg 17 is arranged. This bend 35 is located above the lower frame part 12 in each case. The modifications according to FIGS Figures 5 . 7 and 9 show that each of the adjacent leg portions 38, 40 may have other bends, but need not necessarily.

The above statements with regard to the angled portions are each based on angling of the lower leg 17, because the lower frame part 12 is guided under the lower leg. It is, so to speak, within the reach of a person skilled in the art to allow the lower frame part 12 to extend above the lower leg 17, for which purpose the lower frame part 12 can be bent in the same way one or more times while the lower leg of the arm 4 is substantially straight ,

Barrier according to any of claims 1 to 6, characterised in that the lower frame part (12) is constituent of a protective grating frame (24), wherein the frame (11) has at least one horizontally extending middle bar (11) and an upper sided handle bar (10), wherein an upper leg of the at least one cantilever beam (4, 15) extends materially uniformly in one piece past the at least one middle bar (11) and is connected with it or penetrates through it and extends up to the handle bar (10).
8. Barrier according to any of claims 1 to 7, characterised in that at least two identically formed cantilever beams (4,15) extend in parallel spacing from the upper sided handle bar (10) up to the second longitudinal side (20) of the floor assembly (2).
9. Barrier according to any of claims 6 to 8, characterised in that ends (21, 22) of the at least one cantilever beam (4, 15) have cut-outs (30, 31) which are customised to the cross-section of the handle bar (10) and/or of a longitudinal side frame part (23).
10. Barrier according to any of claims 6 to 9, characterised in that the floor assembly (2) and the protective grating (3) are welded respectively to the at least one cantilever beam (4, 15) which is materially uniformly continuous from its one end (21) to its other end (22).
11. Barrier according to any of claims 1 to 10, characterised in that frame parts (12, 23), bar (11) and the at least one cantilever beam (4, 15) are profiled pipes with the same outer diameters, wherein the wall thickness of the frame sections (14, 23) and bar (11) is smaller than the wall thickness of the at least one cantilever beam (4, 15).
12. Barrier according to claim 2, characterised in that the protective grating (3) is surrounded by a circumferential protective grating frame (9), which is breached only by the at least one cantilever beam (4, 15).
13. Barrier according to any of claims 1 to 12, characterised in that the floor assembly (2) has a floor assembly frame (24), which holds at least one floor plate (25, 26, 27), which is fastened to the floor assembly frame (24) and which does not protrude upwards above the floor assembly frame (24).
14. Barrier according to claim 13, characterised in that the floor assembly frame (24) together with the horizontal, lower legs (17, 18) of two cantilever beams (4, 15) delimits floor areas, wherein in a floor area delimited by two legs (17, 18) a support strut (28) extends from the first longitudinal side (19) to the second longitudinal side (20).
15. Barrier according to any of claims 1 to 14, characterised in that at lateral posts (13, 14) of the protective grating frame (9) are disposed on the one hand upper and lower tabs (7, 8) and on the other hand upper and lower hooks (5, 6), pointing down and matching said tabs, for the connection with hooks (5, 6) and tabs (7, 8) of further barriers (1), wherein the hooks (7, 8) are different in length.
16. Barrier according to claim 15, characterised in that at least one hook (5) is at its end side bent so that only barriers (1) disposed in an angle different from 180° can be connected with one another and wherein the barriers (1) in alignment are locked against one another.
17. Barrier according to claim 15 or 16, characterised in that the hooks (5, 6) have a fastening base which passes through openings in the posts (13, 14) and is welded with the edges of the opening.
