Definitions

  • the invention relates to an air cargo pallet in which a square, quadratic or rectangular shaped light metal plate is bordered on the outer edges by a light metal hollow profi le and is connected to this hollow profi le by means of iete, the light metal hollow profi le next to one lower, closed cavity at the top a cross-sectionally T-shaped, at the end of the T-web open upward longitudinal slot for about pi lz- or ram-shaped longitudinally displaceable and with their pi lz or pusher heads at circular g expanded locations of the upper, open area of the slot insertable and removable holding members of tensioning nets, by means of which the goods to be transported can be lashed onto the pallet, and the miter-cut light metal hollow profiles at the pallet corners are connected to one another at the walking joints against the influence of shear forces.
  • Air f rac htpa Lithuanians of the type mentioned at the outset are said to be particularly light, but on the other hand to be particularly load-bearing.
  • the light metal plate alone cannot guarantee the load-bearing capacity. Under certain circumstances, it would bend depending on the load. That is why the light-alloy hollow profiles initially exert a load-bearing capacity.
  • the light-alloy hollow profiles have another function thanks to their flat outer edges.
  • Airplanes sometimes also ground transport devices and storage facilities, are in fact with holding systems in the form of holding claws or the like. equipped, and the Heilf ra c htpa Lithuanians can be pushed under these holding claws with the flat outer edges. This will prevent them from tipping over at an angle, Accelerations etc. officiated.
  • the upper, open T-shaped longitudinal slots of the light-metal hollow profiles are used to fix the loose transport goods stacked on the pallet to the air freight pa with the help of tensioning nets.
  • Pi lz or plunger heads - similar to window curtains - are inserted and locked in the longitudinal slots at extended locations.
  • the Lei chtmeta l L-Hoh Iprof le have a step-like heel on the underside along the inner edge, in which the Lei chtmeta L Lp Latte is flush with the Lei chtmeta l L hollow profi le and with its edges pushing against the heel and with riveted to the light metal hollow profiles. This results in the highest level of strength and security in relation to loads that act in the plane of the light metal bar and whose tendency is to change the miter angle.
  • the light metal L-Hoh Lprofi Le are welded in known air freight pa lettes of the type mentioned at their miter joints, which requires the use of trained welders. This work is time consuming and expensive. In the area of the weld, the hollow profiles are de-anodized so that a flawless weld is possible. This process also makes the pallets with welded corners more expensive.
  • the disadvantage of this known arrangement is, in particular, that the pins are not exactly in the shear zone, so that they are stressed by the shear forces via lever arms. As a result, very high moment forces act on the plug pins resulting from the shear forces. In view of the fact that the pins have relatively small cross sections and that they are also exposed to strong notch forces, they can therefore easily break off. With such gene designs, the strength of the corner connection is therefore seriously jeopardized.
  • the invention is therefore based on the object to provide a Luf fra chtpa Lette of the type mentioned, in which de miter joints of the light metal hollow profiles are connected without welding and nevertheless withstand high shear stresses.
  • the above-mentioned Gutf rachtpa Lette is characterized according to the invention in that, symmetrically to the miter joint, a lance-shaped or fish-shaped insertion element, which is flat in side view, is inserted at least free of play, preferably clamping, into the abutting lower cavities of the light metal hollow profile, that the insert l has a right-angled tip and a right-angled recess at the fishtail end, that both right angles are arranged symmetrically to the line approximately that the distance between their apexes the length of the opening of the lower cavity of the lei chtmeta L L- Hoh Iprofi L s along the miter line, and that the insert part l is rounded off at its edges.
  • the insert part engages in the miter region in both abutting light metal hollow profi les, or their lower hollow space, so far that loads on a light metal L-Hoh Iprofi L can also be transferred to the other light metal adjacent to the miter without a lever action and without a tilting action by exposing the insert part in the miter plane to shear stress.
  • Appropriate material strength of the insert ensures high resilience and durability.
  • the connection withstands shear forces without damage using the insert.
  • the outer surfaces of the light metal L-Hoh Iprofi Les on both sides of the pedestrian line remain aligned, even with high loads and are only interrupted by the fine cutting line of the miter.
  • the shape of the insert part - right angle at the front, right angle at the back - works on the one hand fixing the position of the insert part and on the other hand fixing on the angle between the two light metal hollow profiles, insofar as this is due to the high rigidity the construction itself is required at all.
  • the corners can be rounded during the individual professional machining. This also reduces the manufacturing costs of the pallet according to the invention.
  • the insert l adapts without play to the correspondingly equipped cross section of the receiving cavity of the light metal hollow profile, whereby the shear force-absorbing connection of the miter joints of the Lucasf rachtpa Lette is further improved.
  • the insert part l is made of light metal and is curved in the longitudinal direction. This makes it possible to compensate for tolerances in the hollow profile L when inserting the insertion part into the abutting cavities of the light metal-hollow profile, which facilitates the installation of the insertion part Les.
  • the curvature is only slight. When installing the slide-in part, this is lifted so that the same is held without play in the hollow profile under clamping action.
  • FIG. 1 shows a reduced plan view of the air formed according to the invention for racette lette
  • FIG. 2 an enlarged plan view of a corner of the Lucasfra chtpa Lette according to FIG. 1, partially broken away, which shows the position of the insertion part within the light metal hollow section Les, 3 - a partial section through the light metal hollow profile of the air cargo range according to the invention with a view of the inserted part according to line AA in FIG. 1,
  • Fig. 6 - a side view of a longitudinally curved embodiment of a slide-in les, exaggerated.
  • FIG. 1 An air freight pallet 1 is shown in FIG. 1. It consists of a square, i.e. depending on the requirements, square or rectangular light metal Lp Latte 2. Usually the light metal Lp Latte 2 is e.g. approx. 2 mm thick light metal sheet with possibly an elo ured surface.
  • the light metal L Lp Latte is connected to light metal hollow profi le 3 anodized by means of rivets 4.
  • cross section of these light metal hollow profiles 3 can, if necessary, be adapted to special requirements and, unlike shown in FIG. 3, can be designed. Basically, however, the cross section always has a lower, at least partially flat, rectangular cavity 5 and above it a slot 6 with a T-shaped cross section, which is open at the T-web end and has some circular extensions 7.
  • the outer edge 8 is rounded or chamfered or the like depends on the application. However, it is important on the inner edge 9 of the light metal hollow profiles 3 that on the underside a stepped recess 10, into which the edge of the light metal plate 2 fits flush and bluntly butt against the step, this space shape together with the rivet ensures maximum rigidity in the plane.
  • the light metal hollow profiles 3 have miter section 11, which runs at an angle of 45 ° to their length.
  • a fish or lance-shaped insert part 12 which is flat rectangular in side view is clamping and symmetrical to the miter plane in the open, lower cavity 5, with each other at the miter joint free of play and pressed together without any contact and pressed in this state with the light metal riveted riveted light metal l-hollow profiles 3.
  • the insert part 12 sits without tilting or levering moment and absorbs all shear forces.
  • the slide-in part consists of Al Mg Si 0.5 F 22 and therefore has high shear strength.
  • the fish shape of the slide-in part is stress-free. At the apex 15 of the tail end 14 there is an additional radius 16. The bulges lie well in the cavity 5, and the fork of the fish bug end 14 is also clamped from above by web areas 17 of the light metal L-Hoh Lp rof i Les 3, whereby high strength is achieved in a material-saving manner.
  • edges of the insert part 12 have a rounding or bevel 18 which on the one hand corresponds to the rounding of the cross section of the cavity 5 and on the other hand facilitates the indentation.
  • a rounding 19 can be ground to every corner of the air fraupta Lette 1.
  • the air fracka Lette according to the invention is highly resilient and corrosion-resistant, has a pleasing appearance and is repairable and easy.
  • corner connection according to the invention can be used in a advantageous manner also in the construction of container floors. These floors have the same design as the Luftfracht pa Lithuanians. As a rule, the skirting board professionals then wear fastening flanges that serve to fasten the wall surfaces.
