Definitions

  • the invention relates to a fastening device for mounting a frame to a wall and a method of mounting with said fastening device according to the independent claims.
  • the support rider with the ears which are formed or attached or attached is attachable to the first fastener with the second fastener.
  • the latter is provided with a second thread to be screwed into the thread of the first fastener.
  • the screwing is done using a driving element coupled to the second fixing element.
  • the ears are designed such that they provide a complementarity of shapes and / or forces with a frame for attachment of the object.
  • the entire ear frame is adjustable relative to the distance between the frame and the wall by screwing or unscrewing the first and / or second fastener.
  • the object of the invention is achieved by a method for mounting an object to a wall with the aid of said fixing device according to the invention.
  • the method according to the invention comprises the steps of attaching the first fastener to the wall with the aid of the first thread; then attach the second attachment element to the support rider with the ears; then attach the second fastener including the support rider with the ears to the first fastener, using the second thread which cooperates with the tapping of the first fastening element, by pivoting one or more fins (4a) of a driving element of the second fastening element; then either clipping the frame to the ears; screw the frame to the ears; and attach the object to the frame.
  • An advantage of the invention lies in the fact that the fastening device allows the use of frames of different materials, thus increasing the flexibility and freedom of assembly of the device. This is reflected in the possibility of attaching frames either by clipping or by screwing. For example metal frames often have a profile for clipping into the ears of the device, therefore resulting in a complementarity of forms, while wood frames are rather able to be screwed between the ears of the device, therefore resulting in a link to forces.
  • Another advantage of the invention lies in the possibility of adjusting the spacing between the frame, already mounted to the ears of the fixing device, and the wall, by actuating the first and / or the second fixing element. This simplifies the assembly process of the frame in accordance with the requirements.
  • the driving element is a free pivot rosette with respect to the first fixing element and / or the support rider with the ears. It has at least one fin for actuating the rotating rosette. This advantageously allows a quick and easy attachment of the support rider with the ears to the structure, simply using the vanes of the rosette to screw the second fastener element in the first.
  • the fins are foldable from a first position, in which the fins essentially form the same plane with the body of the rosette, to a second position in which the fins are folded towards the ears of the device.
  • This advantageously facilitates on one side the screwing or unscrewing of the second fastener (first position) and on the other side to lock the second fastener in a certain position, typically in a screwed position. Locking of this element is important to prevent the second fastener from unscrewing by itself. For example, in the case of use of the device for mounting siding on the walls of a building located near a street, the second fastener could unscrew itself because of vibrations caused by vehicles traveling near the building. Such a situation is avoided with this embodiment of the fins.
  • the fixing device according to the invention is advantageously used for a thermal or acoustic insulation of a building and / or for a coating of a wall of a building.
  • the term “mounting” includes placement and / or final fixation and / or locking of a framework and / or attachment of a facing to the framework. It may also include possible adjustments of the facing with respect to its position relative to the bearing surface.
  • coating refers to insulating plates and / or facings. In the context of this invention this term may also include several coating layers, such as one or more insulating layers, a sealing layer and for example a facing layer. The invention is for example also usable for ceilings or crawling roofs. For the purposes of this document such elements are included in the term "wall”.
  • FIG. 1 shows a perspective view of an embodiment of a fastening device 1 according to the invention in a context of use.
  • a wall 2 is for example a wall or a wall of a building.
  • the wall 2 is coated with an insulating layer 2a.
  • Such an insulating layer may for example be placed on the inside of the wall, and be a panel of wood fibers or glass wool.
  • the invention is also applicable in case of an external insulation of a building.
  • a facing (not shown) is fixed on said layer 2a via the frames 8 attached to the fixing device 1.
  • the frames are typically profiles, for example metal or wood, who wear siding, for example in the form of plasterboard, or in paneling.
  • the fastening device 1 is provided with a bracket 7 serving as a connecting element between the wall 2 and a first fastening element 6.
  • the first fastening element 6 will be described in connection with Fig. 2 and 3 .
  • the bracket comprises a base 7b and a first branch 7a secured to the base 7b.
  • the first branch 7a can also be an independent element attached to the base 7b.
  • the first fastening element 6 is adapted to be attached to said first branch 7a.
  • the fixing device 1 further comprises a second fastening element 5 which will be described in detail in connection with Fig. 4 and 5 .
  • the fixing device 1 is provided with a support rider 3a carrying two lugs 3 and a driving element 4.
  • the support rider 3a is essentially parallel to the wall 2 and its lugs 3 are perpendicular thereto.
  • the base 7b of the bracket 7 is fixed to the wall 2 by means of a third fastening element such as a screw, a concrete anchor, etc.
  • the vertical mounting position of the base 7b is given by the size of the insulation layer 2a.
  • the first branch 7a has a portion substantially perpendicular to the wall 2 and the bracket 7 is provided with several tongues 7c on the side of its free end.
  • the tabs 7c are substantially parallel to the wall 2. They have a dual function; on one side they temporarily hold in position the insulation layer 2a placed below and / or below the branch 7a of the bracket. On the other side, they serve to attach the other elements of the fastening device 1 to the square. Fig.
  • brackets with different lengths of their perpendicular portions of the first branch 7a are provided, depending on the thickness of the insulating layer 2a. It is preferred that this length be slightly smaller than the thickness of the insulating layer 2a, in other words that the tongues 7c of the first branch 7 slightly compress the respective face of the insulation layer 2a so that the insulation layer 2a is in good contact with the wall 2.
  • the advantage of using brackets 7 with said tabs 7c is even more manifest in the case of coating the inclined walls which are retained at the wall 2 by the tabs 7c ( high and low) without having to support them during the attachment of the other support elements of the fixing device 1.
  • a sealing layer 2b (film, or lé) can be placed over the insulating layers 2a.
  • the first fastening element 6 is attached to said first branch 7c by perforating the sealing film 2b through the hole provided in the tongue 7c.
  • the second fastening element 5 comprising a second thread 5a with the driving element 4 and the support rider 3a with the lugs 3 are attached to the first fastening element 6.
  • the frames 8 are attached to the lugs 3 either by clipping or by screwing.
  • the final facing is attached to the structure consisting of the plurality of frames 8 already attached to the wall 2. It is noted that in practice a slot called “technical gap" is provided between the facing and the insulation layer, allowing the passage of ducts, etc ...
  • Fig. 2 shows a perspective view of an embodiment of the first fastening element 6.
  • the first fastening element 6 has a first thread 6a, preferably a thread for screwing into wood.
  • the choice of such a thread advantageously allows an attachment of the first fastening element 6 directly to the wall 2 when it is a wall 2 of wood or with wooden uprights. In this case a square 7 is not necessary.
  • the end 6c of the first fastener 6 is preferably sharp enough to easily pierce the insulation layer 2a without much damage to the insulation. This same end can also be arranged to ensure direct screwing into solid wood without requiring pre-drilling, such as with the use of a self-drilling head.
  • the first fastening element 6 further comprises a sealing washer 12 concentric with respect to the longitudinal axis of the first fastening element 6.
  • the first fastening element 6 comprises a third thread 6b for the attachment of the first element of fixing 6 to the tongue 7c of the square 7 (see Fig. 1 ).
  • the third thread 6b follows the first thread 6a. It is preferred that the diameter of the third thread 6b is greater than the diameter of the first thread 6a. This makes it possible to insert the first fastening element 6 more easily into the hole in the tongue 7c of the bracket 7.
  • the third thread 6b is a metal thread. It is understood that the third thread 6b is not necessary in the case of direct attachment of the first fastening element 6 to the wall 2. In this case, the third thread is directly drown in the wood material constituting the wall 2.
  • the first fastening element comprises a flange 6d, particularly integral with the body of the first fastening element 6 and concentric with respect to said longitudinal axis.
  • a hole with a tapping 6f (see Fig. 3 ) extending along the longitudinal axis of the first fastening element 6 is provided for screwing the second fastening element 5 to the first fastening element 6.
  • the hole 6e has an impression of the Torx type for screwing the first fastening element 6 into the tongue 7c of the bracket 7 or directly into the wall 2.
  • imprint can also be used.
  • the footprint 6th is a hexagonal short footprint type bolt head.
  • Such an impression can assume the function of external drive to cause the attachment of the first fastening element 6 to the wall 2 or to the square 7.
  • Fig. 3 shows only the head portion of the first fastener 6 for reasons of simplification.
  • the fastening element 6 shown in this figure differs from that shown in FIG. Fig. 2 in that it comprises a free metal washer 11 concentric with respect to said longitudinal axis and arranged between the sealing washer 12 and said collar 6d.
  • the sealing washer 12 and the free washer 11 can be used with first fastening elements 6 with other impressions 6e than that shown in FIG. Fig. 3 .
  • the sealing washer 12 for example rubber, is used to reseal the portion of the sealing layer 2b pierced by the first fastening element 6.
  • the sealing washer 12 and / or the free washer 11 may not be necessary if necessary, if the airtightness is achieved by the wall itself.
  • Any wall 2 may receive a sealing system 2b in air film, for example for application from the inside of a building, operating as a vapor brake, or a waterproof system and / or wind for outdoor application.
  • a film 2b is unwound on the insulating layer.
  • the screwing of the first fastening element 6 can cause a twisting of the film 2b when tightening increases, particularly when using the rubber washer with a high coefficient of friction, resulting in a non-uniform seal and possibly a break in the film.
  • the free washer 11 it is possible to avoid such a twist of the film 2b.
  • Fig. 4 shows an exploded perspective view of other elements of the fastening device 1.
  • said drive element 4 is a free pivoting rosette with respect to the first fastening element 6 and / or said support rider 3a with the ears 3.
  • the rosette 4 has four fins 4a integral with or attached to a body 4b of the rosette 4 for actuating the rosette 4 in rotation.
  • the rosette 4 may have more or less fins.
