Definitions

  • a scaffolding system comprising a support of a set of plates and a set of railings, this support comprising two scale assemblies facing each other, each scale assembly comprising at least two uprights and at least two rungs each extending between two uprights to allow access to the deck assembly by climbing on the rungs.
  • a railing assembly includes at least one railing post mounted on a corresponding ladder assembly (eg mounted at one end on one end of a support post, said scale post, corresponding), and at least one rod-type element rigidly secured to a corresponding railing post, and forming with said railing post a railing frame.
  • the system is arranged so that the railing assembly moves from the raised position to the lowered position, and vice versa, by rotating the railing frame post around an axis having a parallel at a time in a plane defined by said railing frame and in a plane defined by the plateau set (said horizontal plane).
  • the corresponding rod-type element and forming with said amount may comprise another amount of railing and one or more elements ( s) spacer extending between said railing posts.
  • the frame can thus have a parallelogram type structure.
  • the rail when the guardrail assembly is in the raised position, can be raised with respect to the plane of the guardrail frame, and in particular extend in a direction normal to this plane.
  • the rail may comprise a hinge, and on either side of this hinge, two portions of the hinge, the hinge allowing one of these hinge portions to be pivoted and folded against the other portion of the hinge. smooth.
  • the scaffolding can be arranged so that whatever the state of the scaffolding system, the folding base remains fixed to the ladder sets and remains in the plane occupied by the folding base at the open state.
  • the scaffolding system may advantageously comprise a first slide element secured to an element of the folding base, and a second slide member, cooperating with the first slide member, and arranged so that when the scaffolding system changes from the folded state to the open state, the first slide member moves from a first position relative to the second slide element, to a second position.
  • the locking device can be arranged to trigger a blockage of the first slide element when said element reaches the second position.
  • the scaffolding device further comprises stabilizing elements 40 and remote wheels 50.
  • the steps 3 can be attached to the uprights 120, 121, 122, 130, 131, 132 by welding. In an embodiment not shown, it may provide a fastening by riveting, or other.
  • the ladder portions 100, 101, 102, and 110, 111, 112 of the same scale assembly 10, 11 are slidable relative to one another in pairs.
  • Locking means here hooks 150 pivotally mounted on the ladder portions intended to be raised, and able to engage with two rungs of two adjacent ladder portions (one rung of the ladder portion on which is mounted hook and a rung of the adjacent ladder portion of the inner side of the scaffold) prevent extended ladder portions from falling back under the effect of gravity.
  • These hooks can thus ensure locking for several scaffold heights, the pitch between these heights being the inter-rung distance.
  • the fixed hinge member 42 is secured for example by welding to the corresponding amount 120, 130 substantially at the level of the highest step 3 of the corresponding scale portion, 100, 110, while the movable hinge member 43 is translatable upward in the y direction when the ladder portions 100, 110 are spaced from each other.
  • Such a system involving a sliding connection and an automatic locking at the end of the race may be more reliable than the prior art in which human intervention was necessary, the operator coming to fix rods by means of pins.
  • the time saving during assembly can be appreciable.
  • a manual unlocking is provided for security reasons.
  • the platform can be placed by means of hooks 71 on the highest steps 3 of the ladder portions 102, 112.
  • each of the uprights defines both a flanged groove 62 and a slide member 65, so that the uprights 120, 121, 122, 130, 131, 132 may be identical to each other.
  • This can make it possible to provide a single scale portion model 100, 101, 102, 110, 122, 112, so that the logistics and supply for manufacturing can be relatively simple.
  • connecting elements 28 connected to the respective uprights 130, 132, defining partial links allowing relative movements between the railing posts 270-273 and the ladder posts 122, 122 ', 132, 132' on which these railing posts are installed.
  • the guardrail assembly 20 can be designed relatively rigidly, because the voltages induced by the height offsets during the vertical deployment will be absorbed by movements of the guardrail relative to the amounts of scale.
  • the assembly element 28 comprises a part 435 intended to be secured to the upright 271 without any particular clearance, for example by means of a rod fixed by riveting 440 to the upright 271, or the like, and a part 433 intended to cooperate with the amount 132.
  • this central portion 438 may be in contact with the lower end of the upright 271.
  • This attachment of the diagonals to the ladder portion may be advantageous compared to a fixation with respect to a pre-assembly on the plate only, Indeed, this telescopic diagonal can be pre-assembled and when the plate is moved, the Fixing between the diagonals and the rest of the scaffolding does not need to be defeated.
  • the installation of diagonals is independent of the set of tray, which can be more reassuring.
  • the folding bases 60 Like the folding bases 60, the folding bases 60 'remain in the vertical plane (yz) when the scale assemblies 10, 11 are spaced from each other along the length z.
  • a support piece 154 On the ring 153 is fixed rigidly a support piece 154, on which the rods 44 are pivotally mounted.
  • each folding base is entirely pre-assembled thanks to the sliding links 43. Thanks to these slide links, each of the rods of the folding base is brought to its position in the automatically deployed state, without particular intervention of the operator.
