Description

The present invention relates to a device

  permanent anchoring in a building element, such as wall, chaining, load-bearing masonry, concrete slab, glued laminated beam or the like, for the non-permanent assembly of a console intended to carry a safety device,

  such as work platform, flying scaffolding or similar.

  There are a large number of built-in masonry devices to accommodate different types of security devices, such as gateways, used most often when developing a construction. These anchoring devices can, however, be classified in two families. The first family concerns the devices integrated in the building element by grounding during the construction of the construction of said element. Anchoring devices consisting of an anchorage box which constitutes a permanent reservation for the attachment of various work safety equipment can thus be cited by way of example. This device consists of a semi-circular plastic casing traversed horizontally by a galvanized iron or stainless steel spindle used both for sealing the device and for hooking, by means of a hook, different materials used. The installation of this anchoring box in the building element must however be provided during construction to facilitate its sealing. In addition,

  such a housing has a large footprint.

  The other family of anchoring devices consists of anchor type devices, such as expansion plugs introduced into the construction element such as

  that wall, after the elaboration of the latter.

  The disadvantage of these devices is their great complexity which makes them relatively expensive. In addition, the designs retained, such as a design based on an expansion of an element, generate, during a pose and

  Frequent removal of this element, wear likely in the long run to no longer give satisfaction in terms of anchoring.

  A first object of the invention is to overcome the aforementioned drawbacks by proposing an anchoring device intended to be incorporated in a construction element, possibly completed, this incorporation being done by

  simple perforation of said construction element by means of a conventional tool.

  Another object of the present invention is to propose a

  anchoring device of simple design making it particularly inexpensive, this anchoring device being able to adapt to any building element.

  To this end, the invention relates to an anchoring device intended to be incorporated in a construction element, such as a wall, possibly completed, for receiving a support bracket of a safety device, such as Work platform, flying scaffold or similar suspension, characterized in that the device consists of a sleeve intended to be introduced into a through perforation formed in the construction element, this sleeve comprising, in the vicinity of one of its ends, an anchor plate intended to be applied against the surface of the perforated construction element, the other end of this bushing being provided with a thread on which is engaged, freely moving, a support plate held pressed against the opposite surface of said construction element by means of at least one clamping member, such as a nut, the socket having a tapping bore die for receiving by screwing a threaded rod carried by the console, said console coming to the end position of screwing the threaded rod, in contact

  against the outer face of the anchor plate.

  Thanks to this general architecture of the device

  The anchoring element is inserted between the support and anchoring plates, thus preventing any movement of the anchoring device within the construction element.

  According to a preferred embodiment of the invention, the tapping of the threaded bore of the bushing and the threading of the threaded rod are arranged to reach, at the end of the screwing stroke, a predetermined angular position.

  fixed console, preventing any positioning error when mounting the safety device.

  Due to the very simple attachment of the console to the anchoring device, it is thus possible to adapt a

  large number of consoles on such a device without having to modify this device.

  In addition, thanks to this arrangement, we obtain an easy anchoring device to mount and requiring no

  User reflection to obtain a secure anchoring of the security device.

  The invention will be well understood on reading the

  following description of an exemplary embodiment, in

  reference to the single figure which shows, partially in section, an anchoring device according to the invention and

  a console intended to be fixed to said device.

  The anchoring device, object of the invention, is intended to be incorporated permanently in a building element 1, such as a wall. Such a device thus allows, throughout the construction or later to the latter, the attachment of different security and work equipment. This attachment is effected via a console 2 which is fixed on the anchoring device, the safety device and / or work (not shown) being itself coupled to said

console 2.

  The anchoring device essentially consists of a bushing 3 introduced through a through perforation formed in the construction element 1. Consequently, the introduction of the bushing 3 in the construction element 1 is particularly simple. This bushing 3 comprises, in the vicinity of one of its ends, an anchoring plate 4 intended to be applied against the surface of the perforated construction element 1. In practice, this anchor plate 4 is generally welded to the end of the sleeve 3 for reasons of ease of construction. This anchor plate 4 is furthermore preferably inscribed in a square with fallen corners to form pins 10 of anti-rotation penetration during the clamping of the

  anchoring device in the construction element 1.

  The other end of the sleeve 3 is provided with a thread 5 on which is engaged, free movement, a support plate 6. This support plate 6 is held pressed against the opposite surface of said construction element 1 by means of at least one clamping member 7. Such an assembly is shown in the single figure in which the building element 1 is represented by hatching, the opposite faces of said building element 1 being shown in dashed lines. . It can be seen that the anchor plate 4 and the support plate 6 enclose said construction element 1. The clamping member 7 may, for example, be constituted by a nut / lock nut system. One can also consider the use of a rod called "Diwidag" (registered trademark) and a winged concrete nut. Other embodiments of the clamping member 7 may still be considered. Once the anchoring device thus set up and incorporated in the construction element 1, it is then possible to fix on this anchoring device a console 2. To allow this adaptation of the console 2 on the device of anchoring, the sleeve 3 has, at its end equipped with the anchoring plate 4, a thread 820 which cooperates with a threaded rod 9 carried by the bracket 2. This tapping and threading are arranged to reach, at the end of the race screwing, a fixed predetermined angular position of the console 2, preventing any positioning error when mounting the safety device. In the end position of the screwing stroke, the console 2 comes into contact against the outer face of the anchoring plate 4. Thus, for example, as shown in the single figure, the console 2, once screwed on the anchoring device, is in a position corresponding to that shown in the disassembled position of the console, that is to say in a position in which the

  console is oriented essentially in a vertical plane.

  Although this console 2 can affect a large number of shapes and is particularly adapted to the fasteners of the safety devices and work it will have to support, this console 2 preferably affects the general shape of a crank, whose outer branches are stiffened by an anti-buckling core 11. In this case, the outer branches and / or the anti-buckling core 11 of the console 2 are provided with hooking and / or fastening points 12, 13 for joining with the safety device or devices adapting thereto . In the case where the safety device is a scaffolding structure, this may be in accordance with that described in patent FR-A-2,245,213. In this case, the attachment member of such a safety device is constituted by a concavity hook facing upwards, this hook being adapted to be introduced into a through hole 13 formed on said 2. The scaffolding structure thus coupled to the console 2 is also supported at one point of the construction to prevent the effect of the tilting torque acting on said structure, in particular when it is loaded in persons and / or in charges. Of course, the fixing of other safety devices may also be envisaged. In practice, the installation of such an anchoring member is carried out as follows. Firstly, the perforation of the construction element 1 is carried out at one or more points, depending on the number of anchoring devices to be installed. The anchoring device, in particular the sleeve 3, is then introduced into the perforation so that it protrudes from the opposite face of said construction element 1. Thus, the anchoring plate 4 disposed at one of the ends of this bushing 3 abuts against one of the faces of the construction element while the threaded rod 5 projects from the other face of this construction element. The support plate 6 and then the clamping members 7 are then introduced. Once the clamping has been completed, the portion of the threaded rod still projecting beyond the clamping member 7 can be eliminated by means of a tool. appropriate cutting. This avoids any risk of injury to a user. When the anchoring device is in place, the console 2 can be screwed to the device. This screwing is done by simply rotating the console 2 once its threaded rod 9 inserted into the threaded bore 8. Once the console 2 in place, it is then possible5 to hang the safety device on said console. When we want to prevent the use of such

  anchoring device, it is sufficient to close the bore 8 by means of a suitable closure member such as a plug. The coating, possibly affixed thereafter on the building element 1, permanently masks the anchoring device.
