Definitions

  • the subject of the present invention is a metal scaffolding of the kind indicated in the preamble of claim 1.
  • Document GB-A-627 989 describes a metal scaffolding comprising metal tubular uprights which support horizontally oriented metal tubular beams to support and retain metal plates, said uprights and beams being provided with reciprocal fixing means constituted by fittings comprising at at least two complementary parts hollowed out with impressions on their faces intended to come into contact, so as to define, after assembly, a cavity of substantially cylindrical shape, suitable for trapping the ends of the side members.
  • the abovementioned interior faces comprise on the one hand other imprints suitable for defining through openings whose longitudinal axis is perpendicular to the longitudinal axis of the cylindrical cavity in order to retain the intermediate or extreme parts of the uprights, on the other hand, through holes cooperate with screws for the assembly of complementary parts of said fittings.
  • the object of the present invention is to produce a metal scaffolding which has remarkable characteristics with regard to the stability and rigidity of the fixing of the beams to the plates, even in the presence of considerable loads, while being capable of being mounted and disassembled very easily.
  • a dependent claim corresponds to a particular embodiment to allow the upper face of these plates to be arranged exactly at the level of the upper part of the assembly fittings, thus avoiding the formation of differences in levels.
  • the dependent claims also relate to a particular configuration of the cavity closed at one end provided in the aforementioned fittings, in connection with that of the ends of tubular beams, in order to prevent any risk of their being released from said cavity.
  • the invention relates to particular embodiments of assembly fittings in order to allow the production of modular structures capable of perfectly adapting to the most varied requirements of the user.
  • the scaffolding according to the invention comprises a series of plates in the manner shown in FIG. 1.
  • the supporting elements are formed by tubes 1 oriented vertically so as to act as uprights. These tubes or uprights 1 are inserted in fittings 2 which trap intermediate parts in the case of the intermediate plates, or end parts in the case of the upper plate.
  • connections further comprise means for their attachment to the tubular elements or side members 3 which act as supports for the plates 4.
  • One of the latter is particularly shown in FIG. 2.
  • said trays are made to have perpendicular extensions 5 which have a fold 6 at the end; the tubular element 3 thus snaps between the extension 5 and the underside of the plate 4, taking advantage of the elasticity of the material and thereby immobilizing the folding 6.
  • This connector is intended to allow the connection between a tubular element 3 forming a support for the horizontal plates, and an upright not shown, suitable for being engaged in a through opening 7.
  • the connector is characterized in that it is produced by two complementary parts 8 which have an imprint 9 on their inner face intended to come into contact with one another. Once the aforementioned faces are brought into contact, the two indentations 9 define a closed cavity at one end with a substantially cylindrical profile in which engages the end of the tubular member or spar 3.
  • Two other cavities 11 are provided on the two parts, capable of defining the above-mentioned through opening 7, the axis of which is oriented perpendicular to that of the cavity 12.
  • the latter are shaped so as to have an intermediate portion 3 'of reduced diameter, at which the indentations 9 have an annular projection 9' established correspondingly.
  • the connector illustrated in fig. 7 and 8 can be considered as a doubling of the previous one. It allows the assembly of two aligned tubes 3 and the fixing of these on the same amount. To this end, two clamping screws 14 are provided, as well as, of course, two closed cavities 12.
  • the angle connection shown in fig. 9 and 10 is made up of three complementary pieces; one of them, referenced 16, has a square profile, while the other two, referenced 15, are absolutely identical to those which form the connector according to FIG. 4.
  • the part 16 with each of the parts 15 defines the cavities 12 for blocking the side members 3; vice versa, the part holes 15 and 16 together define the through opening 7.
  • the two screws 14 fasten two wings of the part 16 on each of the straight parts 15.
  • the fitting which has been illustrated in fig. 11 and 12 includes a part 17 perfectly identical to one of the two which constitute the connection according to fig. 7 and 8, as well as the two angle pieces 16 conforming to the connector according to fig. 9 and 10.
  • the through opening 7 is defined by cavities provided with the same profile on the three constituent parts; the two lateral holes are formed by indentations formed on one of the square pieces and on the elongated piece 17.
  • the cavity closed at one remaining end 12 is defined by the two square pieces 16 once these have been assembled.
  • the previously described fittings give the scaffolding according to the invention a modular character which allows the user to produce assemblies of any shape, in which the load-bearing elements can be oriented in all directions, according to the requirements of structural stability.
  • angles of the plates 4 are shaped so as to have cutouts 18. These allow the upper ends of the fittings to find a place in the spaces delimited by said cutouts when two plates are placed side by side side by side, with the consequence of allowing perfect contact between said plates and avoiding any discontinuity in height between the upper faces of these and the ends of the fittings.
  • underside of the plates may have reinforcing ribs which have not been illustrated.
