Definitions

  • the present invention relates to modular metal structures which are used in the construction of lattice structures such as shelving for warehouses, raised floors or the like.
  • the invention relates to modular metal structures comprising vertical sides connected together by horizontal stringers which support, at predetermined heights, a plurality of supporting elements such as, for example, shelves, flooring or the like.
  • stringers which support, at predetermined heights, a plurality of supporting elements such as, for example, shelves, flooring or the like.
  • suitable removable fastening systems arranged along the vertical sides and at the ends of the stringers, it is possible to provide, with great ease, structures which satisfy the various requirements in terms of both longitudinal and tranverse extension, and also freely arrange the supporting elements at the desired heights.
  • Structures of this type are used not only for constructing small shelving for storing merchandise, or simple raised floors inside depositories or the like, but are also used in the construction of spacious self-supporting warehouses in which the lattice structure also supports the side walls and the overhead covering of the warehouse itself.
  • the distance which separates two sides defines, in the case of the shelving, the maximum width of the spaces for the merchandise. This width coincides with the length of the stringers used to connect the sides.
  • sectional height of the stringers is also important since said height may limit the possibility of vertical access to the spaces for the merchandise.
  • the stringers are greatly stressed since, in addition to connecting together the sides and also partially supporting the weights arranged on the support elements, they must also withstand the knocks to which they are subject as a result of the - often rough - handling of the forklift trucks used to move the merchandise.
  • the load, the distance between the sides and the maximum sectional height define the shape used for the cross-section of the stringer.
  • the most economical shapes for the cross-sections of the stringers are those for which a maximum value of the modulus of resistance is obtained with the minimum use of material. Functional shapes of the section are therefore obtained by distributing the material of the section as far as possible from the neutral axis.
  • the stringers constructed in accordance with the known art are obtained mainly by shaping and folding flat metal sheets so that the rigidity and the maximum length of the stringers are obtained by modifying, where possible, the geometry of the section without varying, however, the thickness used; in this way, as has already been seen, the costs of supplying and storing the material used for producing the elements of the structure are reduced.
  • the section of the stringers is, in the technical sector concerned, mainly substantially rectangular and its dimensions vary in accordance with the variation in length of the stringer or the variation in the load to be supported.
  • the costs of supplying the material which is qualitatively identical for all the various stringers, are minimized, the number of the sections and/or thicknesses of the profiles necessary for constructing any structure is therefore increased considerably.
  • a partial solution to this problem is provided by the use of improved sections in which the thickness of the material distributed at a distance from the neutral axis is increased by folding over the sheet metal onto itself several times so as to create a plurality of superimposed folds.
  • the long sides of the cross-section of the stringers have the basic thickness of the sheet metal, while the short sides, which are further removed from the neutral axis, have a multiple thickness compared to the basic thickness.
  • a further disadvantage of the stringers provided in accordance with the known art consists in their limited transverse rigidity.
  • An object of the present invention is therefore that of eliminating the drawbacks of the known art mentioned above.
  • the invention solves the problem of providing a modular structure for metal shelving which is extremely robust and stable and can be manufactured in an efficient and economical manner.
  • a further object of the present invention is that of enabling the construction of structures which have stringers with extremely compact and strong sections allowing the construction of spacious raised floors or spacious loading surfaces.
  • an object of the invention is that of reducing the costs of the modular structures by means of the use of stringers obtained using a single basic profile for all the lengths and the loads required.
  • a further object is that of allowing the use of extremely low-cost materials for constructing modular structures which are also very complex and robust.
  • a further object of the present invention is that of increasing the rigidity of the modular structure by increasing the transverse rigidity of its stringers.
  • an object is that of allowing the arrangement of the sides at a great distance from one another without thereby negatively affecting the overall rigidity of the structure.
  • the modular structure for metal shelving or the like, forming the subject of the present invention is characterized by the use of stringers obtained by engagement of a basic profile with two solid bars, i.e. an upper one and a lower one, arranged parallel to the longitudinal axis of the profile, within suitable longitudinal engagement zones, so as to adapt the strength thereof to the actual requirements in each case.
  • the solid bar arranged at the top of the basic profile is able to project upwards, from the shape of the latter, and may have a substantially rectangular section.
  • the solid bar arranged at the bottom of the basic profile may have a circular section and may consist of low-cost round iron bars used for the construction of reinforced-concrete structures.
  • this solution limits the number of basic elements necessary for obtaining the maximum modularity of the modular structure and allows one to exploit fully the strength characteristics of very low-cost materials which can be easily found on the market.
  • the modular structure 1 comprises a plurality of vertical sides 10 connected together by horizontal stringers 14.
  • the sides 10 have, along their height, a plurality of slits 11 arranged at a distance from each other.
  • the stringers 14 have, at their ends, brackets 12 provided with fastening tongues 13 designed to engage into the slits 11 for removable joining of the brackets 12 to the sides 10.
  • the stringers 14 each consist, as can be clearly seen in Fig. 7, of a support profile 2 provided with two longitudinal engagement zones, an upper one 4 and a lower one 3, inside which an upper auxiliary bar 6 and a lower auxiliary bar 5 are respectively inserted in a fixed manner.
  • the support profile 2 has laterally two sides 18 along which longitudinal ribs 15 are formed, said ribs having the function of strengthening the profile.
  • the longitudinal engagement zones 3,4 are formed in the zones of the support profile 2 furthest from the neutral axis of the support profile 2 so as to obtain the maximum rigidity.
  • the support profile may also be formed by bringing together two or more support profiles 2 and connecting them firmly together.
  • This constructional variant (not shown) allows the use of a single support profile 2 for the construction of stringers 14 with multiple heights or widths compared to the basic transverse dimensions of the support profile 2 itself. In this way it is possible to obtain a further increase in the rigidity of the stringers.
  • the cross-section of the profile 2 is preferably hollow, but the solution illustrated herein is also applicable in an entirely similar manner to profiles with a solid cross-section.
  • the upper engagement zone 4 has a cross-section shaped in the manner of a "U”.
  • This engagement zone 4 houses inside it the upper auxiliary bar shaped in the manner of a flat strip 6.
  • the depth d of the upper engagement zone 4 is chosen so as to be slightly less than the thickness S of the flat strip so that the flat strip projects, with respect to an upper edge 16 of the support profile 2, by the amount S-d.
  • the cross-section of the lower longitudinal engagement zone 3 is shaped substantially in the form of an upturned "V" and receives a lower auxiliary round-shaped bar 5.
  • the upturned V-shape is particularly suitable for receiving round bars 5 of varying diameters, chosen, in each case, depending on the stresses to which the stringer will be exposed during use. Fixing of the round bars is performed by means of continuous welding or spot-welding 7.
  • Both the auxiliary bars i.e. the upper bar 6 and the lower bar 5 have a solid section for making full use of the modulus of resistance which can be obtained, while leaving the distance from the neutral axis unchanged. In this way, it is possible to reduce the height of the section so as to provide stringers which are extremely low and compact.
  • the length of the stringers may be increased for the same height of the section.
  • the "V" shape of the longitudinal engagement zone 3 is also able to receive bars with a cross-section which is not circular, for example square, flat, rhomboid, hexagonal, etc. and is extremely suited for this purpose. In the case where no round bars are available it is possible to continue production of the stringers by simply fitting them with the bars which are available on the market at that particular moment.
  • auxiliary bars have a solid section and since they are arranged in zones of the support profile 2 furthest removed from its neutral axis, extremely compact and particularly rigid stringers are obtained.
  • the U-shaped configuration of the upper longitudinal zone 4 has the advantage that it simplifies mounting of the flat strip 6 since the latter, once inserted inside this groove, does not require the use of special devices for fixing it during the subsequent welding operations.
  • the same considerations also apply to the lower longitudinal zone shaped in the manner of an upturned "V" where a further advantage is that it is self-centering for round bars 5 of any diameter. Owing to the choice of these particular geometrical shapes it is therefore possible to automate assembly of the auxiliary bars with the support profile so as to limit further the costs for production and storage of the pre-finished stringers.
  • Figure 3 illustrates a constructional variant of the stringer 14'.
  • the sections of the two, respectively upper and lower longitudinal zones 4', 3' which are similar to one another, are shaped so as to be able to each receive, both flat strips 6,5' and round bars 5, as required.
  • This type of profile 14' while being slightly more costly as regards its manufacture, has the advantage that it may be used with auxiliary bars having both a round and a rectangular section depending on the requirement or the availability of the material.
  • Figure 4 shows a further variant of the stringer 14''. Its lower longitudinal engagement zone 3'' has a section which is slightly modified and shaped in the manner of an upturned "V", the two free ends of which terminate parallel with one another.
  • the cross-section of the support profile 2'' is closed by a curled portion 19 obtained by folding over onto one another two adjacent free edges 20, 21 of the profile 2''.
  • the modular structure thus provided therefore achieves the objects indicated. With said structure it is possible to limit the number of basic elements necessary for obtaining the maximum modularity and moreover reduce the dimensions of the stringers, as well as limit the cost of manufacture since it involves the use of extremely cheap materials, assembly of which may be partially automated.
  • All the stringers necessary for constructing both smaller structures and larger structures may in fact be realized by combining with a single support profile low-cost auxiliary bars for obtaining the required rigidity.
