Definitions

  • the invention relates to a device for securing a construction accessory to reinforcements.
  • the invention also relates to a construction element comprising such a device and in particular a construction element comprising a concrete body and at least two reinforcements extending in the concrete body.
  • the invention also relates to a method for fixing such a fastening device to the associated fittings.
  • One object of the invention is to obviate, at least in part, the aforementioned drawback.
  • An object of the invention is also to propose a construction element comprising such a securing device.
  • An object of the invention is also to provide a method for fixing such a device to the frames.
  • the invention makes it possible to be well implanted by being fixed to two separate frames, the arrangement in opposite directions of the legs favoring this good implantation. In particular, this ensures pinching of the invention between the two reinforcements. This makes it possible in particular to avoid a detachment of one of the legs or a tilting of the invention.
  • the invention is simple in construction and inexpensive to produce.
  • the invention is very simple to install on site.
  • the legs of the first and second legs are secured to the receiving means so as to be immobile vis-à-vis said receiving means.
  • the receiving means comprise a sheath serving in service as an anchoring stud for the construction accessory.
  • the reception means comprise at least one plug to plug one of the ends of the reception means.
  • the cap is shaped so that it can be removed from the receiving means.
  • At least the first leg is arranged so that its first leg is at a given distance from a lower end of the device identical to the distance separating the second leg from said first leg at an upper end of the device.
  • at least one zone of at least one of the legs is textured.
  • the two legs of the same leg extend parallel to each other.
  • At least one of the legs of the first leg extends parallel to at least one of the legs of the second leg.
  • the attachment means comprise a third leg associated with the first leg and a fourth leg associated with the second leg so that the attachment means comprise a first pair of legs and a second pair of legs.
  • the third leg extends in the same direction as the first leg so as to frame the same frame and wherein the fourth leg extends in the same direction as the second leg so as to frame the same frame.
  • At least two lugs extend along a first flank of the receiving means and at least two lugs extend along a second flank of the receiving means opposite the first flank.
  • the invention also relates to a construction element comprising a concrete body and at least two reinforcements embedded in the concrete body, the construction element comprising a device as mentioned above arranged in the construction element so that the legs frame each one of the reinforcements and so that the receiving means extend at least partly outside the concrete body.

  • the device will be secured to the concrete body of the construction element so that the construction element delivered on site will already be equipped with the device of the invention. This will allow operators to more easily attach a construction accessory.
  • the invention can be installed at multiple locations on a site, which is very advantageous.
  • the device can be arranged close to free edges of the site (free edge of the floor type, hopper in particular stairway hopper, etc.) in order to that a safety accessory such as a guardrail can be attached to it.
  • locking means (forming part of the device or not) could be used to fix at least one of the legs to at least one of the frames that it frames (such as for example a link made of metallic material).
  • these means are optional, the invention being able to be advantageously implemented by simple insertion of the legs around the frames without additional locking means.
  • the device can be used indifferently in one direction or the other, the device can be asymmetrical.
  • the first end of the first leg of at least one of the legs may be at a given distance from the upper end of the device (along the first axis X) different from the distance separating the first end of the second leg of the same leg at the lower end of the device.
  • the device may include one or more indications of use (for example a particular color, an alphanumeric code, etc.), such as for example at least one indication of its direction of use.
  • at least one indication may be inscribed at the level of the lower end and/or at the level of the upper end of the device and for example on the plug or plugs of the receiving means.
