Definitions

  • the invention relates to an assembly which has an edge of a square hollow body, e.g. forms an ocean freight container and is formed by a steel angle iron arranged at the corner and a component running parallel to it, which hold the edges of lightweight building boards by means of parallel flanges.
  • the lightweight walls made of plywood are fastened with their outer surfaces directly to the flanges of the angle iron made of steel by means of screw bolts.
  • the angle iron can be stiffened in that its flanges are provided with longitudinal beads or in that it has a hollow cross-sectional profile.
  • German patents 2oo 772 and 586 832 from which it is already known to provide a rail-shaped component in parallel with a corner connection for containers in addition to an angle iron arranged at the corner, which is connected to the angle iron is connected by screws and pinches the edges of the walls of the container together with the angle iron between flanges.
  • US Pat. No. 3,261,493 shows an arrangement in which receptacle profiles with a U-shape and a 45 ° angle are provided on the edges of the container walls. Two such holding profiles can thus be complementary to an angle of 0 ° and 9 are to be held together by means of an opening provided at the corner closure bar.
  • the invention has for its object to design the assembly so that it is much lighter with the same strength, or can achieve higher strength with reduced weight.
  • the proportion of the corner assembly weight of an angular hollow body, in particular an ocean freight container, to the total weight is to be reduced, so that the usable filling weight can be increased and the full filling volume of the hollow body or container can be used.
  • this object is achieved in that an edge of an angular hollow body, for example an ocean freight container, forming assembly, in which a corner iron arranged at the corner and a component running parallel thereto, the edges of lightweight boards by means of the edges parallel flanges hold, is characterized in that the angle iron by an enhanced tensile strength fibers - is connected rigidly adjacent the inside reinforcement element made of plastic.
  • the reinforcement of the plastic stiffening element by means of tensile fibers and the rigid connection with the angle iron is of particular importance. 'For this reason, the angle iron in particular can be made much weaker and lighter than was previously possible.
  • the stiffening element can be constructed as a uniform lightweight profile carrier, or it can also be composed of several parts (with an intermediate piece between angle iron and lightweight profile carrier).
  • Parts of the assembly can also be formed by U-shaped profiles and also made of fiber-reinforced plastic, which in turn are assembled with the edges of the lightweight walls. This option is also characterized in the subclaims in various implementation options.
  • the assembly shown in FIG. 1 is used for the edges, which is formed by an angle iron 10o made of steel and lightweight walls 12 and 14, which is fastened to the flanges 16 and 17 of the angle iron by means of bolts. These flanges are stiffened by longitudinal beads to increase their flexural strength heights.
  • the lightweight walls 12 and 14 can be plywood panels that are coated on both sides with plastic or sheet metal. In this embodiment, the required bending strength of the assembly can only be achieved by a relatively large wall thickness and a correspondingly high weight of the angle iron.
  • the plywood walls 12, 14 also contribute significantly to the weight of the container. The result is that a container with a volume of 4o m 3 weighs about 2 t. Since the permissible weight of the loaded container is limited, its volume cannot be fully used if the loaded goods are heavy bulk goods.
  • Fig. 2 now shows an embodiment of the assembly in which the weight of the angle iron 10 can be significantly reduced.
  • the inner walls of the lightweight walls 20 and 22 are in contact with flanges 24, 26 of a lightweight profile carrier 28 which extends along the inside of the angle iron 10 and is rigidly connected to it.
  • This lightweight profile carrier 28 rests on the inside of the angle iron 10. This is provided with surfaces 3o and 32 which extend parallel to the plane 34 which bisects the angle of the angle iron 10.
  • the lightweight profile carrier has the shape of a bar provided with the flanges 24 and 26, which is slidably guided between the surfaces 3o and 32 transversely to the longitudinal direction of the angle iron and the lightweight profile carrier.
  • each lightweight panel 20 or 22 can be penetrated by bolts which connect the two flanges 16 and 24 or 17 and 26. Thanks to this rigid attachment of the lightweight panels 20 and 22 both with the angle iron 10 and with the lightweight profile support 28, the two lightweight walls contribute significantly to the bending strength of the assembly.
  • the lightweight profile carrier 328 has, in addition to the two flanges 324 and 326, flanges 336 and 338 which run parallel to these and which abut against the flanges 316 and 317 of the angle iron 310. 2 differs from that of FIG. 3 in that the two lightweight walls 32o and 322 do not rest with their outer surfaces on the angle iron, but on the flanges of the lightweight profile carrier 328.
  • the individual parts are rigidly connected to one another by means of bolts, just as has been described with reference to FIG. 2.
  • the assembly shown in FIG. 4 differs from that of FIG. 3 mainly in that the lightweight profile carrier 428 is hollow.
  • the outer edges of the two flanges 424 and 426 are also connected to one another by a web 44o.
  • those parts which correspond to the assembly of FIG. 3 are provided with reference numbers increased by a hundred, so that these parts need not be described in particular.
  • further bolts are provided in a plane 442 running transversely thereto.
  • the lightweight walls are omitted in Fig.4. One reaches between the flanges 424 and 436 and the other extends between flanges 426 and 438.
  • the assembly shown in FIG. 5 essentially corresponds to that of FIG. 2; however, the lightweight structural support 528 is hollow and the guide surfaces 30 and 32 on the angle iron 510 are missing. In this case too, the reference numbers correspond to those of FIG. 2, but are increased by five hundred.
  • the subassembly shown in FIG. 6 differs from that of FIG. 5 mainly in that the corner of the angle iron and the side of the light-weight profile carrier which is in contact with it are rounded.
  • reference numerals are used which differ from that of FIG. 5 in that they are increased by one hundred.
  • the lightweight profile carrier 728 is held at a distance from the angle iron 710 by an intermediate piece 746 lying against the inside of the angle iron 71o and is rigidly connected to this and the intermediate piece 746 by the screw bolts arranged in the plane 734.
  • the lightweight walls (not shown) rest with their outer surfaces on flanges of the intermediate piece 746, which has a hollow profile.
  • the lightweight profile carrier 728 is designed as an angle piece, the apex of which lies in a bead of the intermediate piece 746.
  • FIG. 8 The embodiment of the assembly shown in FIG. 8 essentially corresponds to that of FIG. 6. While there, however, the opposing ones Walls of the hollow lightweight profile carrier 628 run parallel to the bisecting plane 634, they extend at right angles to the flanges 816, 824 and 817, 826 in the assembly of FIG. 8, so that they can lie snugly against the end faces of the lightweight walls.
  • FIG. 9 The embodiment of the assembly shown in FIG. 9 largely corresponds to that of FIG. 7; however, the lightweight profile bracket 928 is hollow and its corner is rounded.
  • the embodiment of the assembly illustrated in FIG. 1o essentially corresponds to that of FIG. 2; however, the lightweight profile support lo28 is hollow and the corner of the angle iron 1010 is rounded.
  • the flanges 1016 and 1017 also adjoin the inner edges of the guide surfaces 1030 and 1032.
  • the embodiment of the assembly shown in FIG. 11 differs from that of FIG. 10 mainly in that the angle iron 1110 has a different profile. Because its flanges are provided with beads 1118, according to which the angle iron creates contact surfaces 1148 for the end faces of the lightweight building boards, which extend at right angles to the flanges.
  • a double-walled angle iron 1210 is used, the walls of which are connected by intermediate walls 125o which are transverse to them and enclose a cavity with these.
  • a hollow lightweight profile carrier 1228 is located in this cavity. It can be connected to the angle iron 1210 by means of screw bolts which pass through the angle iron in the planes 1234 and 1252.
  • the lightweight profile carrier is made of plastic and is reinforced by tensile fibers, such as carbon fibers, glass fibers or the like.
  • the lightweight walls consist of two outer skins, an intermediate body made of solid foam and tensile fibers such as carbon fibers, glass fibers or the like to reinforce the lightweight wall. These walls have a wall thickness which is sufficient for thermal insulation, in particular if very low temperatures are to be maintained inside the body enclosed by the walls.
  • the intermediate piece preferably consist of a polyester or epoxy plastic of high strength, which is reinforced by tensile fibers such as carbon fibers, glass fibers or fibers known under the trade name "Kevlar". Thanks to the stiffening of the angle iron by the lightweight profile carrier or the intermediate piece, the wall thickness of the angle iron generally does not need to exceed three millimeters if the length of the assembly is a few meters. This results in a very low weight.
  • the cavities of the lightweight profile carrier and of the intermediate piece can be filled with a solid foam.
  • FIG. 7 Such an assembly is illustrated in FIG. 7, for example.
  • the legs 1220a of the U-shaped strips 1218a are directed away from the edge 1212a of the hollow beam.
  • the legs 1222a of a U-shaped bar 1224a face the edge 1212a of the hollow body.
  • the two flanges 1222a like the flanges 1220a, are also adhesive on the one hand to the flanges 1210a of the angle iron and on the other hand to the legs of the angularly profiled rod 1216a, e.g. by gluing, connected. While at the in
  • the two U-shaped strips 1218a and 1224a are arranged between each flange 1210a of the angle iron and the rod 1216a, either the strip 1218a or the strip 1224a can be omitted.
  • This cavity is covered by the walls of the two strips 1224a, which can optionally be made in one piece.
  • This lining thus forms part of the lightweight profile carrier, which consists of the elements 1216a, 1218a and 1224a and very significantly reinforces the angle iron-1212a, as a result of which the assembly is given a high resistance to bending and buckling.
  • the lightweight walls 1214a can consist of two parallel light metal sheets, the space between which is filled with a foam and which can be connected to one another by holders which are distributed over the surface of the lightweight walls and extend through the filling of foam.
  • FIG. 13 The embodiment of the assembly shown in FIG. 13 largely corresponds to that of FIG. 12a. This applies to the lightweight walls 1334 and to the strips 1338 with U-shaped profiles on their edges, which correspond to the strips 1318.
  • the U-shaped profiles 1224a of FIG. 12a are, however, replaced by angular profiles 1344, each of which has only one flange 1342, which abuts the angle iron flange 1330.
  • the other flange is thereby on the angularly profiled rod 1336 attached that it has two ribs 1345 and 1347 on the outside, which surround the wall of the strip 1344 and are adhesively attached to it.
  • the cavity 1346 is created. Like the cavity 1226a, this can be filled with foam.
  • the edge of the angularly profiled rod 1336 is chamfered in this case.
  • the embodiment of the assembly shown in FIG. 14 differs from that of FIG. 13 mainly in that the two strips 1454, which consist of fiber-reinforced plastic and are provided on the edges of the lightweight walls and correspond to the strips 1344, are connected to one another by a profile section 1455 , which is adhesively attached to the beveled edge of the bar 1456.
  • the cavity 1466 can be filled with foam.
  • the subassembly illustrated in FIG. 15 differs from that of FIG. 12a mainly in that the legs of the angularly profiled rod 1576 are stiffened by thickenings 1577. For the sake of simplicity, the lightweight walls and the angle iron are not shown in FIG. 15.
  • FIGS. 12a-15 A particular advantage of the assemblies shown in FIGS. 12a-15 is that they can be assembled very easily and quickly.
  • the steel angle iron at the corner with a plastic reinforcement reinforced by tensile fibers letting the element work together can be realized in different ways.
  • the stiffening element can take different forms and can also be constructed from different parts.
  • the stiffening element can in particular also appear in the form of the described lightweight profile supports (for example 28, 728), intermediate pieces (for example 746), U-shaped profiled strips (for example 1218a) etc.
