Definitions

  • This invention refers to improvements made in modular bearing structures such as scaffoldings (e.g. for supermarkets and the like) and, in detail, in bearing elements or uprights for said modular structures. More specifically, the invention concerns a cold-rolled element, particularly suitable for forming the vertical bearing columns and having modular structures and, according to the invention, forming also a guide means or limit end for the support and connection elements and further for supporting load elements (brackets).
  • a cold-rolled element particularly suitable for forming the vertical bearing columns and having modular structures and, according to the invention, forming also a guide means or limit end for the support and connection elements and further for supporting load elements (brackets).
  • the main characteristic of the section element is that it is made-up of bearing cold-rolled or extruded steel section, for forming modular structures such as scaffoldings and the like, having near the external edges two projections formed by bending and forming with side end surfaces two hollow spaces for the insertion and for the bearing of linings for connecting the structure, and the two end faces having at least a plurality of central through holes foreseen for the insertion and the bearing of supports or brackets holding the load.
  • the main novelty of this invention is the fulfilment of a section made up of two symmetrical pieces, that are welded in its ends without requiring to make a bearing edge bended for directing the welding, as happened in preceding solutions used for making similar products.
  • the section is made up of two support elements substantially squared o rectangular in form, that are welded with one another in the head side.
  • the cold- rolled section is made-up of a sole homogeneous section in continuous form, that allows to use at the maximum extent the characteristics of the used material, holding two stiffening ribs made by bending and using a proper bending machine, then they are made completely by cold machining and without welding in this work phase.
  • the section owing to its form with external projections or ribs, can be combined with metal linings, or with linings of any other material that is applied also in said hollow spaces made in the same section.
  • the column o upright being made of a sole welded body joining two symmetrical parts, assures the maximum stiffness and lightness.
  • profiling machine can make profiles having different width so that they can satisfy well-established exigencies, as it is also possible to join specularly the two sections with evident material economy and reduction of stocking dimensions.
  • the steel cold-rolled or extruded section shown with the general reference 1 has an opened squared or rectangular form with wings 2 and 3 and a central element obtained by bending for forming two projections 4, 5 and two free plane faces 7, 8 for resting the panels supported by said element.
  • the two projections 4, 5 are obtained by bending/extrusion applying a suitable mechanical cold machining.
  • the two projections limit one or more rows of rectangular through equidistant slots 6, foreseen for cooperating with hanging teeth of support brackets, that are well-known, or with teeth of metallic panels used as covering 9, these last ones having in plan view a section CO ( Figure 3) conjugated to said projections 4, 5 and locking said projections.
  • the two projections 4, 5, as a first aspect supply a great stiffness to the upright, while as a second aspect, they allow to make hollow spaces for limit end 7, 8 of the covering panels 9.
  • Making the head welding K it is avoided the drawback of the preceding constructions that were required to have a support edge between the two sections in the contact ends, while this new solution allows to spare a fair material quantity (ab. 5-10%) and further a bending machining, therefore it is obtained, when working a great material quantity, a big money spare both for the manufacturer and for the user.
  • the weight of the uprights having a length of 2-3 metres is highly lower than the ones of traditional solutions.
