Definitions

  • the invention relates to a flexible Schutzverbauung supporting energy absorbing structure for flexible protective structures against stone chipping, felling, avalanches or the like.
  • a Schutzverbauung is from the US-A-5,299,781 known. From the document DE 203 00 821 U, there is known another antislip, logging, avalanche, or the like, which includes an assisting energy absorbing structure, a trapping structure, a supporting structure connected to the trapping structure by a connecting structure, and energy absorbing elements.
  • the energy absorbing elements in this case support the connecting element structure in the region of their attachment in the ground in that the fastening of the connecting element structure in the ground is effected by rock anchors or the like via the energy absorbing elements.
  • the invention relates to a flexible protection against stone chipping, felling, avalanches or the like, which is integrated directly into the interception structure of the protective structure, so that a large part of the energy input, introduced by a falling, rolling or jumping rock body or the like already by the combination interception structure and supporting energy absorbing structure can be reduced.
  • connection elements such as steel cables or the like
  • the connection elements structure is either directly connected to the interception structure used (for example. Ring network, Omega network or the like) and / or with their braid overlay.
  • This connection can be made by means of conventional connecting elements, such as: clamping shackles or the like, or the connecting element structure can be sewn or looped with the interception structure (for example: ring net, omega net or the like) and / or its braiding support.
  • the number of fasteners used, called in a further consequence middle ropes, and their distance from the support cables is the Schutzverbauung used, or adapt their energy intake class.
  • Fig. 1 shows the side view of a first embodiment of a protective barrier against stone chipping, felling, avalanches or the like.
  • the Schutzverbauung has a interception structure 1, which is shown schematically by a dashed line. It is connected in the example case by an upper support cable 2 and a lower support cable 3 with the elements of a support structure 10.
  • the modular structure of such protection systems is divided into an interception structure, a connection structure, a support structure, its anchoring and, if necessary, a foundation.
  • the interception structure 1 preferably has coarse-meshed network elements 1 (for example: ring network, omega network, etc.), which are supported in part by the application of small-mesh braids, in order to prevent penetrating small impact bodies.
  • the task of the interception structure 1 consists, as the name suggests, in the interception of the impact body. By plastic deformation of the network elements, a part of the introduced by the impact body kinetic energy is reduced.
  • the interception structure 1 is connected to the support structure by means of a connection structure.
  • the connection structure comprises one (or more) upper support cable (s) 2 and one (or more) lower support cable (s) 3, also called edge cables, which are stretched from column head to column head (or from column to column foot) over all system fields.
  • the support cables 2, 3 are fastened either to elements of the support structure or through rock anchors 9 on the ground. They span the interception structure with the support structure.
  • retaining ropes 6 which connect the head sides of the support structure elements (z.B .: in one embodiment as pendulum supports) on the mountain side with the ground by means of an anchorage (eg rock anchor) 9 and keep it in a statically determined position. If the main elements of the support structure are not connected directly to the ground with rock anchors or the like (for example: in the case of floating mounting), retaining ropes are additionally attached in the foot region of the support elements.
  • connection structure supporting cables 2, 3 and retaining cables 6
  • energy absorbing elements 8 By means of said energy absorbing elements, a large part of the energy input is dissipated via plastic and / or elastic deformation.
  • the support structure has carriers 10 whose length (installation height) and their horizontal spacing (field lengths) are determined by the expected energy input. In general, field lengths of about 10 m are common.
  • the support 10 is preferably carried by way of floor panels 5.
  • the connection of the supports 10 to the floor panels 5 takes place either via a pendulum joint (pendulum support) or it is produced as a fixed connection (welded, bolted or the like).
  • the bottom plate 5 is connected to the ground directly connected by rock anchors or the like or is stored floating and retained with retaining ropes on the mountain side.
  • a pendulum support of the head portion of the carrier 10 is retained with retaining ropes 6 mountain side and kept in a statically determined position.
  • energy absorbing elements 8 of the most varied design and mode of operation.
  • the energy absorbing elements 8 are used in close association with the connection structure. They are installed in combination with the retaining ropes 6, 2.3 supporting cables and / or their guide in the region of the support structure. Further, it is possible to provide energy absorbing members which are selectively connected to the intercepting structure through a connection structure (e.g., steel cables). As a result, the interception structure is directly supported by energy absorption elements.
  • the supports 10 of the support structure are mounted on the said floor panels 5, preferably via a pendulum joint.
  • the bottom plates 5 are fixed with rock anchors 9 on the ground.
  • the carrier 10 are biased back with retaining ropes 6 at the head end and held in position.
  • the retaining ropes 6 are supported in the region of their anchoring 9 by energy absorbing elements 8.
  • the Verbausystem shown is equipped in the illustrated embodiment with two middle ropes 7 at different heights. These cables 7 are connected in the illustrated case with the interception structure 1 over its entire length (except in the region of the carrier 10). In the area of the support or the support structure 10, the cables are guided by cable guides (here shackles), laterally they are supported by energy absorbing elements 8 and fastened with rock anchors 9 to the ground.
  • cable guides here shackles
  • Fig. 2 a second embodiment of the protective barrier according to the invention is shown, in which all parts of the embodiment according to the Fig. 1 are identified with the same reference numerals. Accordingly, reference may be made to the foregoing.
  • central cables 7 ', 7'',7''' are provided. As Fig. 2 illustrates, these are preferably parallel to each other and also parallel to the upper support cable 2 and lower support cable. 3
  • Fig. 1 makes this embodiment during the assembly of the overall arrangement, a curtain-like mounting of the interception structure 1 between the carriers 10 possible, wherein the interception structure 1 can be arranged folded on one or more of the carrier 10 prior to assembly.
