Definitions

  • the present invention relates to an element for protection against avalanche departures or for securing slopes according to the preamble of claim 1.
  • the invention relates in particular to those elements which are towering up in the mountains on avalanche-prone slopes to break or catch snow avalanches or scree avalanches.
  • the invention also relates to such elements which are used for slope protection on steep slopes in the mountains, for example in road construction, when relatively steep cuts are dug into mountains and the adjacent soil or debris is to be retained by the road.
  • Such avalanche protection elements are known in the art in various forms and shapes.
  • an avalanche barrier element with a screen-like structure in which a cross-clamped diagonal supports a network is clamped, which is to provide a protective wall for the retention of particular snow avalanches.
  • This avalanche protection element has proven to be useful for lighter snow avalanches.
  • the relatively fragile net is not adequate to provide sufficient support.
  • this known avalanche protection element has the disadvantage that the network has only relatively small passage openings or meshes. As a result, even plants and animals are significantly disturbed by the avalanche protection elements, which are often installed in several rows and across the whole area.
  • avalanche crosses of four cross-shaped, interconnected in the middle steel girders are known, in the endangered terrain in the mountains are made. Due to their size and three-dimensionality, these avalanche protection elements, which consist of four supports, are relatively bulky and spoil nature. In addition, these avalanche protection elements are only suitable for breaking avalanches. Safe retention of, for example, scree avalanches or securing steep slopes is difficult with them.
  • the avalanche protection and anti-theft protection device as defined in claim 1 comprises a front bulkhead and a framework therebehind, on which the bulkhead forming the front is mounted. Furthermore, at least one rigid strut is provided, which is mounted on the back of the scaffold and serves to support or anchor the avalanche protection element on the ground or in the ground.
  • the element according to the invention is characterized in that the protective wall consists of horizontally and parallel to each other mounted on the frame logs and that the framework of only horizontally and vertically extending supports is constructed in the form of a frame. Due to the frame-like shape of the framework on the back of the element, a high inherent rigidity and torsional rigidity of the framework is generated.
  • the framework in the form of a frame, d. H. with at least two vertical and at least one horizontal beam or two vertical and two horizontal beams, is inherently so stable and rigid that it has a high strength, regardless of the round wall mounted thereon itself, evenly over almost the entire protective surface. This has the advantage that, for example, in case of damage to individual elements of the front bulkhead they can be easily replaced without causing damage to the underlying scaffolding.
  • the framework of the element is smaller in area than the front bulkhead.
  • the protective wall which forms the visible side, has a relatively large area and yet there is a secure hold due to the underlying frame-like framework.
  • the protective wall By forming a protective wall of horizontal, mounted on the frame logs, the protective wall itself has a relatively high strength and can, for example Safely hold large boulders or pieces of ice away without damaging the element.
  • the round timbers also have the advantage that they can be produced, for example, from tree trunks and thus from a renewable material.
  • the protective wall of the element is formed from round timbers which are detachably mounted on the vertical supports of the frame-like framework.
  • a detachable assembly of round timbers a single round wood of the protective wall can be easily replaced if necessary. This is even possible under load, if, for example, the element for slope protection from the back with soil and debris is piled up, as the other elements or round logs of the protective wall continue to provide a relatively large-scale, good grip and the elements taken individually solvable and thus interchangeable are provided.
  • loops of cables or bands are provided for the assembly of round logs of the protective wall to the vertical supports of the frame-like framework.
  • metal cables made of a non-oxidizing metal material or metal strips made of a material of this kind can be used as loop-forming cables or bands.
  • plastic cables or cables or ropes made of a natural material such as hemp or the like can be used.
  • the holder of Round logs on the supporting framework can thus be realized with relatively simple means. It is no longer necessary to provide the spacers respective spacers or slide stops, as was partially required for example in the prior art.
  • the attachment of round logs with loops on the scaffold also has the advantage that the round logs themselves do not need to be pierced and thus it does not lead to a reduction in the natural strength of, for example, logs or specially made round logs.
  • loops are provided on the vertical supports of the framework, which have means for opening and re-closing the loops and / or changing the loop diameter.
  • the loops can be easily adjusted if necessary to suitably large round logs. It is also possible to loosely insert the round logs into the loops or to fix them by tightening the closure means by clamping in the loops.
  • the means for opening the loops also have the advantage that the individual round logs can be easily replaced without much effort.
  • such an element to protect against avalanches can be assembled only in place in the high mountains, so that only the skeleton with the strut, for example, has to be transported by helicopter in the high mountains and the logs from tree trunks in place and site can be cut and then mounted by the technicians on the scaffold.
  • the framework of the element has a substantially H-shape with at least one central horizontal support and at least two vertical supports fixedly connected thereto.
  • the H-shape of the scaffold has the advantage that with relatively high strength and torsional stability with as little material and as few carriers as possible a scaffold is provided, which provides a sufficient attachment for the horizontally arranged round timbers of the protective wall.
  • such an H-shape of the framework can also be considered as an H-shape be used, in which instead of only one horizontal center carrier, two spaced apart horizontal center supports are present.
  • the vertical supports of the framework are preferably set back slightly from the outer ends of the protective wall or their round timbers, so that the largest possible element is provided, which consists essentially and in the visible region of the round timbers and their high intrinsic strength.
  • the framework of double-T-beams is formed.
  • the use of double T-beams has the advantage that a very high strength of the scaffold is offered against hitting snow and scree avalanches.
  • T-bars have a higher buckling resistance.
  • the use of T-beams has the advantage that they have no hard to reach cavities, so that an anti-oxidation treatment, for example by a hot-dip galvanizing or painting with a rust-proofing paint, is much easier. The maximum possible service life of the elements is thereby higher.
  • the element at the back of the frame at least one rigid strut in itself, which is connected via flexible cables with the corners or sides of the framework.
  • the rigid strut on the back has the advantage that the avalanche protection element can be placed with a slight slope on a slope or a surface.
  • the strut serves as a kind of rear support.
  • the strut may also serve for anchoring in a back soil, which is poured behind the element, for example, in the case of a slope protection in road construction.
  • the rigid strut has such a strength that it ensures the substantially upright standing of the protective wall.
  • the cables connected to the framework between the free end of the strut and the corners or sides of the framework have the advantage that, depending on the form of use, one or the other of the cables or cables is subjected to tension and a secure stability of the element is ensured. without the need for rigid, inflexible and expensive three-dimensional support structures.
  • the strut is hinged to the back of the frame and can be changed to adjust, for example, the angle of inclination of the element in the erected form.
  • a desired slope can be easily adjusted or the element can be easily adapted to the existing inclination of the terrain at the installation, for example by adjusting the length of the flexible cables or cables that are connected to the free end of the strut.
  • the rear strut is provided at its free end with anchoring means.
  • anchoring means for example, a flange with holes or an eyelet can be provided, via which a screw or a tether can be attached for anchoring.
  • anchoring means on the strut may also be provided an anchor plate with a certain weight, which is mounted on the end of the strut.
  • the anchoring plate may for example also be hingedly connected to the free end of the strut.
  • closed loops for mounting the round timber are provided on the supports of the frame of the element, which have a slightly larger inner diameter, preferably by about 5% to 10% larger inner diameter than the outer diameter of the round logs of the protective wall ,
  • the round logs can be mounted by simply inserting them sideways.
  • the loops in the form of rigid, ie non-detachable loops can be realized with high strength, so that they offer an even greater holding power against avalanche impact or the backward pressing of, for example, rain-softened soil in the case of slope protection.
