Definitions

  • the present invention relates to a method for producing a safety net, to a safety net, and to the use of such a safety net for protection from avalanches, falling rock or timber, mudslides, earth flows, or for slope stabilization.
  • Safety nets of the abovementioned type are installed for this purpose on a slope, for example, in order that falling rocks, wood, snow avalanches or similar are securely captured.
  • Such safety nets are known, for example, from EP-B-0 979 329.
  • a coherent mesh netting is woven out of individual wire strands, wire ropes or wire bundles. These wire nets are produced such that they are ready for installation and are then rolled up for storage and transport. A relatively large amount of space is therefore required for this.
  • a further drawback consists of the fact that the prefabricated nets in the rolled-up state are under tension, so that they uncurl explosively when the net roll is opened. If such a net roll accidentally becomes undone and opens during transport, particularly by helicopter, this presents a serious hazard. Yet even at the site of installation itself, the opening of the net roll, for the above-stated reason, poses high risk of injury for the installers.
  • One object of the present invention is therefore to provide a method for producing a flexible, hard-wearing and weatherproof safety net of the type mentioned in the introduction, which allows simple, rapid and unproblematic production, storage, transportability and installation of the safety net.
  • the inventive method for producing a safety net comprises the following steps:
  • the inventive method enables the production of a safety net for protection from avalanches, falling rock or timber, mudslides, earth flows, or for slope stabilization, in a simple manner.
  • inventive method is in particular advantageous since the individual net elements can be produced, stored and transported individually. Thus there is no need to transport a large, heavy and bulky net, but rather it is possible to transport individual net elements and to complete the safety net at the site of installation, or at least in the vicinity thereof.
  • the inventive method is not, of course, limited to the production of a net consisting merely of two net elements connected by a connecting net element, but rather, within the meaning of the invention, any number of net elements can be connected by respectively a connecting net element arranged between two net elements.
  • the inventive method thus allows simple adaptation of the size of the safety net according to requirement:
  • the length of the safety net can be varied, on the one hand, via the length of the individually produced net elements and/or of the connecting net element and, on the other hand, via the number of net elements which are connected to one another by connecting net elements.
  • an already prefabricated net can be retrofitted with additional net elements.
  • the individual net and/or connecting net elements do not necessarily have to have the same height.
  • the height of the net or connecting net elements is here regarded the direction transverse to the longitudinal direction of the safety net.
  • a further advantage of a safety net produced according to the method of the present invention lies in the fact that damaged net elements can be replaced by new ones, by an individual damaged net element being removed in its entirety and by a new replacement net element being arranged parallel to and at a distance from the existing safety net, so that the replacement net element according to the inventive method can be connected to the existing safety net.
  • pre-existing safety nets can be retrofitted with additional net elements.
  • holding and fastening ropes can be threaded directly into the net without further connecting means, which in turn allows a material and weight reduction.
  • such safety nets are fastened at their upper and lower edge to supporting ropes.
  • the net elements and, according to the embodiment of the safety net, possibly also the connecting net elements can be folded in a zigzag pattern and placed one upon the other, and it is possible to introduce supporting ropes directly into the folded net. Installation in the terrain, and particularly under confined spatial conditions, is thereby made considerably easier, since the net does not have to be extended in length for the fitting of fastening ropes.
  • the inventive net production is also possible as a line production and allows both a manual production of the safety net and a partially automatic or fully automatic production.
  • At least the first and second net element are produced respectively from just a single rope.
  • the connection of the two ends of the rope, or connecting rope, is preferably realized such that the two oppositely directed rope ends are connected in an overlap region, preferably by means of press-clamping, welding or potting.
  • the fact that the two rope ends are oppositely connected means that they can also absorb large tensile forces and the net elements are particularly stable.
  • just a single connecting rope is guided between the first and the second net element.
  • at least a part of the respective first rope edge portions of the first net element is here connected to at least a part of the second rope edge portions, lying opposite the first rope edge portions, of the second net element.
  • connection of the respective rope edge portions of the first and of the second net element to the connecting rope is realized at connection points located respectively between the respective rope junctions of the connected rope edge portions.
  • connection of the respective rope portions of the first and of the second net element to the connecting rope is preferably realized by looping and/or welding and/or with the aid of guide means and/or with the aid of clamping means.
  • the ropes are not clamped in guide means, but merely guided. That is to say that the guide means is displaceable along the two respective connected rope portions.
  • the guide means it is also possible, of course, for the guide means to be configured such that it is fixed to a rope portion and is merely displaceable along the other rope portion which is to be connected.
  • sleeves or rings for example, can be used.
  • clamps in particular cross clamps, stirrup clamps or ferrules, can be used in a known manner.
  • a connection of the respective rope edge portions of the first and of the second net element to the connecting rope by looping or by means of guide means is particularly preferred, for it enables an articulated connection of the net elements to the connecting net element in the region of the connection points.
  • Such an articulated connection allows a zigzag-like folding together and/or rolling up of the safety net transversely to the longitudinal direction of the safety net, which makes the storage and transport of the safety net considerably easier.
  • all first rope edge portions of the first net element are connected to all second rope edge portions of the second net element with the aid of the at least one connecting rope.
  • first net edge portions of the first net element and/or the second net edge portions of the second net element are movable relative to the connecting rope of the connecting net element. This means that the respective rope edge portions are displaceable along the connecting rope between the two respective rope junctions, or at least articulately connected.
  • This mobility of the net edge portions relative to the connecting rope allows stresses generated, in particular, in the absorption of heavy dynamic loads in the safety net to be ideally distributed.
  • the local force effect of the impacting loads can thereby be distributed evenly in all directions, which ensures a particularly high energy or force absorption capacity.
  • the described mobility of the net edge portions also lends the safety net a particularly high flexibility, which means that the safety net, in the absorption of loads, can plastically deform in the direction of pull of the weight and can thus dissipate the high kinetic energy which is generated upon the impact of loads.
  • the mobility of the net edge portions relative to the connecting rope allows greater adaptability of the net to the nature of the terrain.
  • connection of the rope edge portions to the connecting rope by looping is particularly preferred, since it allows, on the one hand, the mobility of the net edge portions relative to the connecting rope and, on the other hand, a reduction in weight.
  • the net elements can thereby be folded in a zigzag pattern and placed one upon the other. Apart from the advantage of easier transportability of the safety net which has been folded in this way, supporting or fastening ropes can be introduced directly into the folded net. This yields considerable space savings, since, both in production and installation, the net does not have to be spread out in length and hence much smaller distances must be covered.
  • the ends of the ropes of the first and of the second net element and the ends of the connecting rope of the connecting net element are arranged respectively oppositely to each other and are self-contained by means of a permanent connection.
  • the permanent connection is realized preferably by means of stirrup clamps or ferrules.
  • the connection can also be realized in a known manner by knotting, welding, potting, or by means of ferrules.
  • An enhanced stability of the safety net can be achieved by the intersecting rope portions of the ropes and/or of the connecting ropes being stabilized at the junctions.
  • the intersecting rope portions of the ropes and/or connecting ropes, at the junctions are therefore connected by means of clamps, ferrules, guide means and/or by welding or potting.
  • a connection by means of stirrup clamps or cross clamps is particularly preferred in this regard.
  • steel wire ropes are preferably used for the production of the net elements and/or of the connecting net element.
  • plastics ropes is also conceivable. If wire ropes are used, regard should be given to their flexibility, and the rigidity associated therewith, as well as their corrosion resistance, so that galvanized steel ropes, in particular having a preferred thickness of 6 to 12 mm, are preferably used. Wire or steel ropes consisting of a plurality of twisted rope strands are generally used, though the use of one individual steel wire of appropriate thickness is also conceivable. Similarly, the wire ropes can be provided, for protection, with a protective casing, for example of plastic.
  • ropes made of synthetic or natural fibers can also be used for the production of the net.
  • the first and the second net element are produced in identical construction in terms of their height and shape.
  • the two net elements have in the longitudinal direction of the safety net an equal number of rows of junctions.
  • the number of columns of junctions of the first net element does not in this embodiment have to be the same as that of the second net element.
  • the two net elements can thus have a different length. This is particularly of advantage if an existing safety net has to be extended by a specific length.
  • the second net element can be produced in terms of its length such that it expands the existing safety net by exactly the desired lengthening.
  • the first and the second net element are produced in identical construction in terms of their size and shape.
  • the size of the net elements, or of the safety net is fixed by the respective length in the longitudinal direction of the safety net and by the respective height in a transverse direction, running at right angles to the longitudinal direction, of the safety net.
  • the first and the second net element should in the longitudinal direction have an equal number of rows and in the transverse direction of the safety net have an equal number of columns of junctions. It is thereby ensured that the first and the second net element are mutually matched in terms of structure and their respective rope edge portions can be stably connected with the aid of the connecting rope.
  • the first and the second net element are also produced from the same material and by a same production method.
  • the production process can thereby be simplified and, if need be, can also be realized semi-automatically or fully automatically.
  • the connecting net element is also produced in identical construction in terms of shape.
  • a safety net has a regular shape and consists of repeating, structurally identical units of net and connecting net elements.
  • the safety net can be produced from fine-meshed and/or wide-meshed net elements, or connecting net elements, according to requirement.
  • the ropes of the first and of the second net element are guided such that each of the net elements thus produced has in the longitudinal direction of the safety net a plurality of rows of rope junctions and in a transverse direction running at right angles to the longitudinal direction of the safety net a plurality of columns of rope junctions, and the at least one connecting rope is guided between the first and the second net element such that a self-contained connecting net element having just a single column of connecting rope junctions, which column is arranged in the transverse direction of the safety net, is obtained.
  • the prefabricated net elements have a certain longitudinal extent. It is thus possible to produce a longer net within a short time. If the net is intended to be transported already prefabricated, in a preferred manner, then, particularly if the respective rope edge portions of the net elements are articulately connected to the connecting rope (for example by looping), it is also possible to fold together the prefabricated net transversely to the longitudinal direction of the net in a zigzag pattern, like a type of “concertina”, for transport. In this way, a stack in which the individual net elements bear substantially stresslessly one upon the other or one against the other can be formed. During installation, supporting ropes are introduced directly into the folded net, which makes installation in the terrain, and particularly under confined spatial conditions, considerably easier, since the net does not have to be extended in length for the fitting of fastening ropes.
  • the above embodiment allows, on the one hand, easy transportation of the individual net elements and, on the other hand, rapid on-site production, since the connecting net element can be comfortably produced on-site only once the net elements are connected, and thus a longer net can be rapidly produced with the aid of the prefabricated wider net elements.
  • the ropes of the first and of the second net element are guided such that each of the net elements thus produced has just a single column of rope junctions, which column is arranged in a transverse direction of the safety net running at right angles to the longitudinal direction of the safety net, and the at least one connecting rope is guided between the first and the second net element such that a self-contained connecting net element having just a single column of connecting rope junctions, which column is arranged in the transverse direction of the safety net, is obtained.
  • inventive method is not, of course, limited to the production of a net consisting of just two net elements connected by a connecting net element, but rather, within the meaning of the invention, any number of net elements can be connected by respectively a connecting net element arranged between two net elements.
  • the individual net elements have just one column of rope junctions, their size and their weight, in comparison to net elements having a plurality of rows and columns of rope junctions, are significantly smaller.
  • an articulated connection of the respective rope edge portions of the net elements to the connecting rope (for example by looping of the connecting rope with the respective rope edge portions of the net elements) is particularly preferred, since this enables the factory prefabricated net to be tightly rolled up, or the individual net and connecting net elements to be folded together in a zigzag pattern and stacked one on top of the other, for transport.
  • the above embodiment has the advantage that the net and connecting net elements can be particularly well stacked, stored and transported.
  • the length of the net can be exactly adapted at the site of installation.
  • the ropes of the first and of the second net element are guided such that each of the net elements thus produced has in the longitudinal direction of the safety net a plurality of rows of rope junctions and in a transverse direction running at right angles to the longitudinal direction of the safety net a plurality of columns of rope junctions, and the at least one connecting rope is guided between the first and the second net element such that a self-contained connecting net element having a plurality of rows, arranged in the longitudinal direction of the safety net, and a plurality of columns, arranged in the transverse direction of the safety net, of connecting rope junctions is obtained.
  • both the net elements and the connecting net element have a certain length. Whether completion is made at the factory or, possibly, at the site of installation, it is thus possible to produce a longer net within a very short time.
  • an articulated connection of the respective rope edge portions of the net elements to the connecting rope (for example by looping of the connecting rope with the respective rope edge portions of the net elements) is particularly preferred, since this enables the individual net and connecting net elements to be folded together in a zigzag pattern and stacked for transport.

  • the connecting net element 203 also has just a single column S of connecting rope junctions 209 , which column is arranged in the transverse direction Q of the safety net 200 .
  • the respective ends of the ropes ( 204 , 204 ′) and the respective ends of the connecting rope 108 are arranged such that they oppositely overlap each other and are permanently connected in their overlap region 211 by means of a ferrule 212 .
  • both the first net element 301 and second net element 302 and the third connecting net element 303 are once again produced in identical construction in terms of their size and shape and are preferably produced respectively from a single rope.
  • the shown shape of the first net element 301 , of the second net element 302 , and of the connecting net element 303 is known to the person skilled in the art as a diagonal grid or Curry grid.
  • the first net element 301 and the second net element 302 have respectively in the longitudinal direction L nine rows R, and in the transverse direction Q of the safety net 300 , five columns S of rope junctions 305 , 305 ′.
  • the connecting net element 303 also has in the longitudinal direction L nine rows R, and in the transverse direction Q of the safety net 300 , five columns S of connecting rope junctions 309 .
  • the respective ends of the ropes 304 , 304 ′ and the respective ends of the connecting rope 308 are respectively permanently connected.
  • first net element and/or the second net element and/or the connecting net element can also respectively be produced individually from a plurality of ropes, or connecting ropes (not shown).
  • the first and/or the second net element and/or the connecting net element can have a different height. This means that the net elements and/or the connecting net element can have in the longitudinal direction of the safety net a different number of rows of junctions. A particularly good adaptation of the safety net to the local conditions is thereby enabled.
  • the first and the second net element can be produced in identical construction in terms of their height and shape, yet can have a different length. This means that the two net elements, in the longitudinal direction of the safety net, have an equal number of rows of junctions. In the transverse direction of the safety net, the number of columns of junctions of the first net element does not have to be the same as that of the second net element.
