Definitions

  • the present invention relates to an anchor device on rafters for roofing works.
  • Devices of this type are known, such as, for example, that described in document FR-A-2,544,367, intended for anchoring scaffolding or the like during roof repair work.
  • This device comprises elements which are fixed on the rafter by enclosing it laterally.
  • This kind of device is relatively complex to set up and, once in place it cannot be moved.
  • Another device of this kind is described in document FR-A-2,566,820; it consists of several foldable and adjustable elements, anchored on a stirrup placed around the rafter.
  • the structure of the device is more like a heavy structure, that is to say adapted to long-term work, without being able to be easily moved, depending on the progress of said work.
  • a device according to the preamble of claim 1 is proposed in patent BE-A 632,278.
  • the scaffolding presented consists of a plurality of devices gripping the rafters and intended to support a plank floor.
  • Each of these devices consists of an arrow comprising an end piece in the form of a fork or stirrup which is intended to embrace the rafter.
  • This stirrup has two lateral branches constituted by flat bars and is provided with a movable plate forming a stop intended to bear on the upper surface of the rafter.
  • the two lateral branches also have at their free ends a number of openings through which a rod associated with a plate is introduced in order to be placed under the rafter after introduction of the fork-shaped end piece. In this way the blocking of the device against the rafter is ensured by the two support plates and the lateral branches complete the closure.
  • This element in the form of a locking tab can only be but in place once the device is positioned on the rafter and such a system does not provide complete security. It is also necessary to constantly support it when positioning or adjusting it.
  • the invention aims to eliminate these drawbacks by making a light device that is easy to install on a rafter and to move on the same rafter to, for example, follow the progress of the site.
  • Another object of the invention is to provide a device offering multiple possibilities to users, in terms of site construction, and especially in terms of security.
  • the suspended part comprises means for receiving gangways and candles or the like, adjustable, so as to adapt, as a function of the inclination of the rafters, the angle and in particular the squareness of these means with respect to horizontally.
  • the device comprises an articulation disposed substantially in the center, between the suspended part and the part enclosed on the rafter.
  • Locking means for these two parts, one part relative to the other, adjustable, make it possible to adapt the squareness of the suspended part according to the inclination of the part enclosing the rafter.
  • the removable lateral side consists of a latch articulated on the axis of the central blocking pad, which latch comprises at its end anchoring means at the level of the end pad.
  • This latch forming one side of the frame of the part enclosed on the rafter, may include a hinge to allow its positioning between the battens.
  • This latch may also include an adjustable stop, disposed inside the frame to allow automatic adjustment of said frame to the width of the enclosed rafter.
  • the removable lateral side of the anchoring device consists of the curved part of a cane-shaped element, the rod of which is slidably mounted and lockable in a sheath secured to the suspended part.
  • This curved part cooperates, in the closed position, with means for closing the frame.
  • the anchoring device also comprises means making it possible to immobilize it in a positive manner on the rafter to avoid any untimely sliding movement relative to the latter, due to tremors or shocks for example, during the positioning of the gangways , candles or others.
  • the device comprises, integral with the frame, an elastic complementary member, intended to bear on the rafter in particular on its upper surface, to enclose it between said complementary member and the shoe located at the end of the frame, under the rafter.
  • this elastic complementary member consists of a sheath secured to the lateral wing of the frame enclosing the rafter, inside which slides a rod supporting a hook intended to grip on the rafter; a spring is disposed between the lower end of the sheath and a base secured to the lower end of the rod.
  • this complementary member consists of a lateral arm articulated on the central axis and permanently subjected to the action of a leaf-shaped spring trapped at the end of the arm and resting on a eccentric stop towards the rear of the central axis, on the side of the suspended part.
  • the system can also be fitted with a tightening strap, fixed at one of its ends at the end of an axis passing through an articulation socket, the other end being fixed at the other end of this axis. after surrounding the rafter to ensure a reliable connection between the frame and said rafter.
  • This strap can be provided, between its two ends, with rapid tightening means.
  • the device comprises, at the free end of the suspended part, at least one foot for receiving candles or railings, the inclination of which can be adjustable according to the slope of the frame to give said candles or railing a substantially vertical appearance.
