Definitions

  • the invention relates to a method for manufacturing a beam for a storage rack, in which method a profiled beam of suitable cross-section is pressed together or pressed flat at both ends and hooks are provided there for engagement with holes in uprights in the storage rack which are provided with rows of holes.
  • the invention also relates to an arrangement for beams for storage racks, which beams are designed to be fastened to uprights provided with rows of holes, each beam consisting of a section of suitable cross-section, the two ends of which are pressed together to form a plane surface in each case, which extends in the longitudinal direction of the beam, which plane surface is connected to a, preferably angle, section with hooks, bent out from the side connected to the plane surface, for engagement with holes in said rows of holes.
  • a supporting beam which, together with a corresponding, parallel supporting beam, constitutes a horizontal "shelf on which the pallets can rest.
  • a supporting beam usually consists of three parts, namely a beam section of a given length and a fitting (end attachment/locking piece) at each end of the beam.
  • Said fittings are equipped with a form of hook/lip for fixing into corresponding holes in vertical frames/uprights.
  • the fittings are normally joined to the beam sections by welding.
  • a disadvantage of this is that the weld has to be lacquered or painted afterwards, which involves a considerable production cost.
  • it particularly advantageous to use galvanized sections and end attachments because the welding destroys the thin zinc layer, so that the weld is susceptible to corrosion. The weld thus needs to be lacquered or painted afterwards, which increases the production costs of supporting beams.
  • Another embodiment of supporting beams in pallet racks is one where the supporting beam is made in one piece and the section itself of the supporting beams is flattened at each end and hooks are formed directly in the flattened section material.
  • a disadvantage of such an embodiment is that it is then necessary to have the same material thickness and quality in both the beam section itself and the end attachments, with the result that, by optimizing the material in the beam section itself, that is, to use the minimum amount of material to give the desired load bearing capacity, too little strength is obtained in the end attachments, or that, by optimizing with regard to the end attachments, the material consumption in the beam section is excessive and uneconomical.
  • the present invention relates to pallet racks in which the supporting beams consist of a number of parts, that is to say the beam section itself and the associated fittings.
  • the advantage of this is that it is possible to select different thickness and qualities for the fittings or end attachments in relation to the beam section itself.
  • each of the pressed-flat ends is brought into contact with an end section, which end section is provided with hooks for engagement with the holes in the uprights, and in that the pressed-flat beam end and said end section are interconnected by discrete material portions, which form rivets, being pressed through the pressed-flat beam end from the angle side.
  • an arrangement as mentioned in the introduction is also proposed, which arrangement is characterized in that the plane surface and said «nd section are in mutual contact and are interconnected by discrete material portions, which form rivets, pressed through the plane surface from the angle side.
  • the pressed-together or pressed-flat beam portions are located at the two beam ends, but it is also possible to imagine beam embodiments in which one or more pressed-flat or pressed-together beam portion(s) is or are present between the two beam ends, which beam portion or beam portions is or are provided with one or two end sections as mentioned, if appropriate a U section with hooks bent out in the U bottom.
  • the joining technique employed is a "riveting" technique which can be performed by a pressing tool being introduced partly into the two plates which have been placed together and pressing out a discrete material portion in such a manner that a type of rivet connection is formed.
  • the invention results in the production costs of pallet racks being reduced considerably, especially when compared with welded and lacquered solutions.
  • Fig. 1 shows a front view of a supporting beam according to the invention
  • Fig. 2 shows a section through the supporting beam in Fig. 1 along section line II;
  • Fig. 3 shows an example of a pallet rack with supporting beams according to the invention;
  • Fig. 4 shows a pressed-flat beam section end and an angle section before joining together;
  • Fig. 5 shows the two components shown in Fig. 4 joined together;
  • Fig. 6 shows an end view of the supporting beam in Figs 1 and 5;
  • Fig. 7 shows a top view of the end detail in Fig. 5;
  • Fig. 8 shows a front view of a possible beam embodiment according to the invention
  • Fig. 9 shows a section through a typical "rivet" connection.
  • the supporting beam 1 shown in Fig. 1 consists of three components, namely a beam section 2 and an end section for each end, the end sections being in the form of angle sections 3 and 4 having in cross-section two arms substantially at right angles to each other.
  • the beam section 2 has a cross-sectional shape known per se as shown in Fig. 2, and the beam section is shaped like this by bending a plate into the shape shown in Fig.
  • Reference number 5 indicates suitable connections made by a joining technique as described hereinafter with reference to Fig. 9.
  • the beam section 2 is pressed flat at each end, that is to say it is designed with a pressed-together portion 6, 7 in such a manner that, at each end of the supporting beam 1 , a plane surface is formed, which extends in the longitudinal direction of the beam.
  • the rows of holes in the uprights 10 are not shown in greater detail, however, as this technique is well known to the person skilled in the art.
  • the angle side 8 provided with the hooks or the claws 9 is placed against the pressed-together beam end portion 7 and is connected thereto by discrete material portions 11, which will go into and through the plane surface 7 and each form a rivet connection, being pressed out from the angle side 8, more specifically from that side thereof where the hooks 9 are pressed out.
  • FIG. 9 shows a section through a typical "rivet" connection known per se which can be used.
  • the angle side 8 bears against the pressed- together beam end portion 7.
  • a pressing tool 20 presses the material of the angle 8 and of the end portion 7 against a female reaction member 21, by means of which a rivet connection as shown is formed.
  • the individual beams 1 will be made as shown in Fig. 1, but it is also possible to imagine supporting beam embodiments in which pressed-flat portions are designed between the ends provided with fastening fittings, at which portions fittings are mounted, so that therefore, as shown in Fig. 8 for example, a supporting beam 1' can extend over and past an upright 14 arranged between two uprights 12, 13. Angle sections 16, 17 are then, like at the beam ends, fixed into the intermediate pressed-flat portion 15. If appropriate, the two angle sections 16, 17 can be designed as an integrated unit, and also as a U section. Beam embodiments such as that shown in Fig. 8 can suitably be used to produce a storage rack which is better held together and more stable, so that, for example, the storage rack shown in Fig. 3 then has longitudinal beams which thus extend from the upright 12 to the upright 18 in Fig. 3.
  • the advantages mentioned in the introduction are achieved by means of the invention.
  • the individual elements can be treated in advance, for example galvanized or lacquered.
  • the use of angle sections in the end fittings also provides increased stability in the storage rack.
