Definitions

  • the present invention relates to a pneumatic carrier according to the preamble of claim 1.
  • Pneumatic carriers of the type mentioned are known and are based on a cylindrical basic shape according to WO 01/73245. This basic form has been further developed into a spindle-shaped carrier according to WO 2005/007991.
  • An advantage of such pneumatic carriers is their low weight and the extremely small transport volume, since the inflatable body is too collapsible and the tension members can be formed as ropes.
  • a disadvantage of such pneumatic carriers is that although they can carry high surface loads (loads distributed over the length of the carrier), they are only limitedly suitable for asymmetric loads in comparison to the possible surface load, in particular with regard to concentrated axle loads, which is particularly the use as a bridge decisively hinders, as a rolling over a bridge axis, such as a truck, in this respect represents a particularly unfavorable case.
  • Figure 1 shows schematically a pneumatic, here spindle-shaped carrier 1 according to the prior art, with the clarity because of exaggerated thickness.
  • An inflatable consisting of a flexible material body 2 holds under operating pressure a pressure member 3 of a tension member 4 in an operable distance, again for the sake of clarity on the pressure member 3, a planking 5 is indicated, which allow driving on the bridge formed by the carrier 1 should.
  • the following thought model can explain how the wearer works:
  • the compression member In the case of an asymmetric load, however, the compression member increasingly sinks into the body 2 at the location of the load, and bulges upwards therefor, with a tendency to buckle over the working surface on the body 2, and thus from this lift, which has an increased risk of buckling and thus relevant reduced load capacity of the carrier 1 result.
  • FIG. 2 a shows an improved spindle-shaped carrier 10 according to WO 2005/042880, which is provided with connecting elements arranged vertically (i.e., in the loading direction and perpendicular to the longitudinal axis of the carrier 10), designed as pure tension members 11.
  • the distance a of the tension members 11 is to be optimized by the skilled person with regard to the specific case.
  • the tension members 11 are suitable for preventing an asymmetrical load to a certain extent that the pressure member 3 lifts off at a non-loaded location of the body 2 and thus kinks.
  • the vertical tension members 11 only cause the pressure member and the tension member to deform approximately equally (similar bending line), they are not capable of reducing the amount of maximum deflection. However, it arises locally Fixing point 12 for a tension member 11 a considerable stress (for example, additional bending moments) in the pressure member 3, which in turn is undesirable.
  • FIG. 2b shows a possible arrangement of the tension members 11 in a carrier 10 'according to WO 2005/042880, wherein a plurality of tension members 11 are arranged in the manner of a bifurcation in the distance to be determined by the person skilled in the art and in a symmetrical arrangement relative to each other, starting from a common attachment point 13 ,
  • This arrangement appears suitable to reduce the above-mentioned undesired stress in the pressure member 3, since the attack of the tension members 11 is distributed to a small, the attachment point 13 opposite distance. The reduction is only local.
  • a disadvantage of the arrangement according to WO 2005/042880 is that the pneumatic system is still severely deformed under load.
  • a trained as a rope tension member (but also designed as a long, thin rod tension member) and the pneumatic body 2 allow movements that lead in case of load despite sufficient carrying capacity to a large deformation of the carrier, be it at a researchernlast and, reinforced, at an asymmetrically attacking load, such as in the case of a busy bridge.
  • the tension members 11 according to WO 2005/042880 damp strongly the tendency to buckling of the pressure member 3, 4 ', but again lead locally to lifting the tension member 4, which in turn makes a deformation of the entire carrier 10' feed and ultimately the desired Success regarding buckling of the pressure member 3 again reduced.
  • the connecting element between the pressure member and the tension member zigzag extends over a plurality of connection points
  • pressure from the pressure member in the tension member can be derived (although the connecting elements are designed as tension members), so that recorded between the pressure member and the tension member shear stresses can be analogous to the shear stresses in the web of a double - T carrier.
  • the arrangement according to the invention correspondingly stiffens a pneumatic support, for example by five times, or, in the case of the relevant asymmetrical load, by a factor of ten, as will be shown below on the basis of a simulation calculation.

According to the figure, they are so large in the embodiment shown that their height corresponds to the height of the subsequent pneumatic Druckgropers 23. Essential and independent of their respective geometric design is that they connect the pressure member 24 with the tension member 25 such that they can initiate the pressure or train exerted by them in the other member (tension member 25 and pressure member 24).
  • the end nodes as shown in the figures described below or also as shown in FIG. 1, may be made smaller or, for example, such that the tension member engages directly at the end of the pressure member.
  • an end node is present when the pressure member and the tension member are connected directly or via a geometrically arbitrarily formed end member with each other such that the pressure acting in the pressure member in the tension member and acting in the tension member train are introduced into the pressure member, said This creates pressure in the tension member and in the pressure member.
  • the pressure member 24 transmits substantially axial pressure and is accordingly designed as a pressure rod, while the tension member 25 transmits axial tension and thus has a flexible design. It can be det, for example as a rope. Of course, it is also possible to form the tension member 25 as a rod, but then so that it can bear the resulting tensile stress during operation. Thus, preferably, the tension member 25 may be pressure-resistant, so that the carrier 20 can also absorb load from below, as both sides of the top (load P) and also from below, in the opposite direction of the load P, can be loaded.
  • Adjacent pressure bodies 23 encounter each other under operating pressure with their right and left end faces 30,31, so that there is the effect of a single, continuously extending from end node 21 to end node 22 over a length pneumatic pressure hull, which is also according to the invention as such.

  • Diagram 120 shows the deformation of the pressure members 110,120 of the carrier 105.115 under the load P m, where concise, the pressure member 110 of the carrier is shifted 105 according to the prior art at the location of the applied load P m by 107 mm down the pressing member 120 of the present invention Carrier 115, however, only by 21 mm. It is also evident as the pressure member 110 of the carrier 105 according to the prior art ⁇ bulges laterally, the pressure member 115 but not.
  • Diagram 121 shows for the deformation of the tension members 111,121 for the centrally acting load P m , the deformation of which is very similar to that of the pressure members 110,120 according to diagram 120, which is likely to be due to the effect of arranged at a distance of tension members 107.
  • Concise is on the respectively very similar deformation of the compression and tension members of the two carriers (prior art - invention) beyond the massively reduced deflection at all, which accounts for about 20% of the carrier 105 according to the prior art in the inventive carrier 115 - Which is a consequence of the inventive arrangement of the connecting elements.
  • the diagrams 122 and 123 show the deformation of the pressure members 110, 120 and the tension members 111, 121 of the carriers 105 (prior art) and 115 (according to the invention) due to the laterally acting load P s . According to the advent of the pressure member 110 and the tension member 111 of the carrier 105 are strongly deformed, with a depression at the location of the load P s and a bulge in the other half of the carrier 105th
  • the deflection of the pressure member III and tension member 121 of the carrier 115 according to the invention is even more reduced than in the case of the centrally acting load P m : the deformation of the carrier 115 according to the invention is from 181 mm (carrier 105 according to the prior art) to mere 20 mm, ie reduced to about 10%, again as a result of the inventive arrangement of the connecting elements.
  • the carrier 115 solves the problem posed and, in particular for asymmetric loads, is considerably more rigid than the pneumatic carriers according to the prior art.
  • This stiffening results over the distance in which the connecting links are continuously guided through the carrier in a zig-zag.
  • this also leads to the fact that the risk of buckling for the pressure member 120 is significantly reduced, which significantly increases the carrying capacity (or its safety factor for a given load) of the carrier 115 relative to the carrier 105 of the prior art.
  • the pressure member is located on the side of the load engagement on the pneumatic pressure body, and the tension member on the side facing away from the load attack.

Abstract

L'invention concerne un élément porteur pneumatique comportant des corps pneumatiques (61 à 63) qui peuvent être mis sous pression et qui maintiennent espacés et en ordre de marche un élément de pression (51) et un élément de traction (52), ce qui produit un élément porteur pneumatique ayant une capacité de charge élevée mais qui présente l'inconvénient d'une déformation élevée en fonctionnement. Les éléments de liaison (57, 58) qui s'étendent en dents de scie entre l'élément de pression (51) et l'élément de traction (52) sur la longueur de l'élément porteur (50) sont de préférence des contrefiches de poussée réalisées sous la forme de tirants flexibles et ils renforcent l'élément porteur (50), par rapport aux éléments porteurs selon l'état de la technique, de sorte que sa déformation dans le cas d'une charge asymétrique, comme c'est le cas avec un pont franchi par des véhicules, n'est plus que de 10 %, par exemple.
