Definitions

  • the present invention relates to the technical field of scaffolding.
  • a conventional scaffold comprises two ladders with stiles and tubular steps and of round section, the ladders being connected to each other vertically by at least two diagonal bars fixed in cross and on each side of the scaffolding , the bars being fixed at their ends to ladder steps.
  • a collar section slightly greater than the section of a post slides along this amount, which amount has a plurality of holes distributed along its longitudinal axis through which is engaged a pin which limits to the less in a sense the translation of the collar.
  • a fixing device which comprises two complementary flanges forming a collar.
  • the operating means consists of a plurality of bolts which pass right through the flanges. This type of device allows to fix the insert at any point of the amount but has a major drawback which is the time required to tighten and loosen the flanges. Also, it is not uncommon for the individual responsible for tightening these flanges to accidentally forget to tighten at least some of the bolts.
  • “Semi auto” type joints are also known. These joints are composed of stays whose flattened ends are provided with a crimped axis of rubber serving as an axis of rotation to a sheet steel jaw, the rotation of this jaw encompassing the profiles of the scaffold plane.
  • the present invention aims to provide a device for fixing a scaffolding element, in particular a smooth, a sub-smooth or a diagonal, this device, while maintaining a simple configuration and economical manufacturing, eliminating the aforementioned drawbacks by providing blocking safety, with possibility of viewing a bad lock.
  • the invention relates, in a first aspect, to a scaffold assembly comprising a first part, in particular a diagonal, provided with a through hole, and a second part, in particular a ladder, provided with a reservation, and a device for fixing the first part on the second part, the fastening device comprising a first end portion adapted and shaped to pass into the through hole of the first part to go to lodge in the reservation of the second part and thus forming a support shaft for the first part, this fixing device comprising a rear portion adapted and shaped to clamp the second part, during pivoting of the device around said support axis, the clamping force obtained increasing during this pivoting .
  • the fixing device advantageously comprises a gripping zone provided with an elastomer sleeve, allowing a more pleasant handling, even in cold weather, or when the device has received fat.
  • the scaffolding 1 shown in FIG. 1 comprises vertical uprights in ladders 2, ground-biased on flanges 3, these ladders 2 being spaced in the direction of the length of the scaffold by ramps or rails 4.
  • the scaffold is stiffened by sub straights, stays, and diagonals 5.
  • This device is obtained for example by folding a steel wire or other metal alloy.
  • the second end portion 12 of the device 6 is an ergonomic grip area.
  • this second end portion of steel wire is coated with a rubber sleeve forming annular projections of the type of those seen in FIG.
  • the three sections 9, 10,11 give the device 6 a stirrup shape adapted to come marry an amount 13 of the scaffolding.
  • the first and third sections 9, 11 are not exactly parallel to each other.
  • these three sections define a U whose base is the second section 10 and whose wings are reentrant, the base of the U being wider than its opening.
  • the device secured or not to the diagonal 14 (or a smooth, a sub-smooth, a ramp) is first introduced by its first end portion 8 into a hole of the upright 13.
  • the fitter then grasps the handle 12 of the device 6 to rotate it about the axis defined by the first end portion 7.
  • the device exerts a progressive tightening of the amount 13 from locking the scaffolding element 14 against this amount 13.
