Definitions

  • the disadvantage is that in the described construction of a pneumatic carrier load can basically be taken only in a predetermined direction; Moreover, depending on the training of the blowable base body restrictions in the guidance of the tension member or in the combination of the beams to a composite such as a roof, a wall, a bridge, etc.
  • Carriers become known, which possess different properties.
  • such a pneumatic support is well suited not only for receiving uniformly distributed symmetrical but also asymmetrical loads.
  • Fig. Ib is a longitudinal section through the carrier of Fig. Ia
  • Fig. Ic the carrier of Fig. Ia and b, half folded
  • Fig. 3b shows a cross section through the carrier of Fig. 3a
  • the web 12 is also operatively connected to the base body 2, here on the one hand via the pressure member 3 and on the other hand via the tension member 4, which both rest on the base body.
  • Rule in the rootstock 2 is also operatively connected to the base body 2, here on the one hand via the pressure member 3 and on the other hand via the tension member 4, which both rest on the base body.
  • the train caused by the internal pressure in the web 12 focuses on the side of the pressure member 3 in the joints 10, since the web 12 is connected only to these and thus initiates the corresponding forces only in this.
  • the joints 10 are thus fixed by the web in its operative position on the base body, so that a collapse of the carrier 1 is prevented by buckling of the pressure member 3 at the location of the joints 10.
  • the carrier 1 can, on the one hand, be readily folded without it having to be disassembled, since the flexible web 12, and also the flexible tension member 4, can adapt to the folded pressure member 3.
  • this configuration is self-operational, which keeps the assembly effort small.
  • Joints 10 on the web 12 is also asymmetric load of the carrier 1 possible without a constructive overhead must be driven.
  • the web 12 is now arranged and designed such that it fixes all hinges 10 of both members 22, 23 in an operable position in the inflated state of the main body.
  • the tension / compression member 23 only absorbs tension. But since it is also pressure-resistant, it has compression rod sections connected by the joints 10, which are stiff; Thus, it is sufficient here if the web 12 initiates the forces transmitted through it only in the region of the joints 10; the load capacity of the carrier 1 is not reduced, as would be the case if instead of the tension / compression member 23 a flexible tension member 4 (FIG. 1b) would occur. Conversely, this also applies to a load acting according to arrow 9 from below.
  • the main body 31 is formed as a spindle, which is constricted longitudinally under operating pressure through the web. It is also possible to form the main body 31 as a cylinder, which is constricted longitudinally through the web. The constriction forms half chambers 32, 33 in the main body 31.
  • Fig. 3b show the carrier 30 of Fig. 3a in cross section along the line BB of Fig. 3a, with the pressure member 3, the tension member 4 and the web 12.
  • the Halbkammem 32, 33 are penetrated longitudinally from the web 12.
  • the pressure member 3 is located on the base body 2 at the location of the web 12 caused constriction.
  • the tension member 4 which is here protected by a sewn bag, for example 35 against lateral slipping or against external influences (weather, dirt, etc).
  • a bag although not shown in the figure, of course, be provided for the pressure member 3.
  • Fig. 3c shows the carrier 30 in a view from the side, wherein the base body 31 along the section line 11 is partially cut.
  • the web 12 is arranged and formed such that it initiates the forces transmitted by it on the side of the pressure member 3 in the area of the joints 10, and distributed as uniformly as possible on the side of the tension member 4.
  • the hidden part of the web 12 is indicated by the dashed line 14.
  • the pressure member 3 is formed bent upward, but may also be straight (Fig. 1) or bent towards the bottom, as long as it is opposite to the neutral fiber of the loaded carrier 30 in the pressure zone and the tension member corresponding in the tension zone.
  • the support 30 may be readily formed analogous to that of FIG. 2, i. two tension / compression members connected by the web 12, so that it can be loaded from above as well as from below.
  • the described pneumatic support 1, 20 and 30 can be to a Composite, such as a roof, a wall or a bridge.
