Definitions

  • the present invention relates to a sealing anchor.
  • the present invention describes a sealing anchor element for insulating elements, in particular mineral wool elements.
  • connection is subsequently carried out in a conventional manner by mounting the insulating elements using conventional fixing means, such as nails or screws with flat heads, etc ...; these fixing means generally pass through the insulating elements. Therefore, the heads of the fixing means are visible.
  • the layer of insulating elements is often previously coated with a light concrete, for example an acoustic coating. This however requires an additional coating operation. This is why it is often desirable to lay insulating elements on a ceiling which include, for example, beforehand a layer of light concrete finishing, in a secure and permanent manner.
  • the fixing means used do not pass through the insulating elements, so that the visible side is not altered by the view of certain parts of the fixing means.
  • insulating elements are placed on an external formwork and are fixed, as a lost formwork, by means of determined fixing devices, on the finishing concrete or in it.
  • the concrete contains a steel reinforcement which must be located at a minimum distance of 15 mm from the surface of the concrete layer.
  • Conventional supports, opposite the frame are provided for this purpose.
  • U-shaped anchoring elements comprising a pointed tongue, a core and a sealing part, elements connecting solidly, for example, to a ceiling of the insulating elements with several layers based on mineral wool, which may also include a layer of light concrete on their visible side.
  • Such U-shaped anchoring elements are inserted by the pointed wing of the U in the abutment face of a mineral wool plate, so that the other wing of the U is applied parallel to the surface. of the insulating plate.
  • the wing of the anchoring element for sealing of flat shape, applied to the surface of the insulating plate, is brought into a position perpendicular to the surface of the plate. insulating and is then covered with concrete, so that the sealing part, after the concrete has hardened, is integrated into it and an effect of adhesion and retention is thus obtained.
  • the present invention overcomes these drawbacks.
  • the invention relates to sealing anchor elements for insulating elements, in particular mineral wool elements, comprising an engagement part intended to engage in the material of the insulating elements, a guide part in order to ensure a guide on a surface of one of the insulating elements, a core connecting the engagement part to the guide part and a sealing part.
  • the latter has a bearing face for reinforcements, located at a minimum distance from the surface of the concrete layer, distance corresponding to the concrete covering required.
  • the bearing surface thus produced, eliminates the costs caused by additional measures taken for the support of the frame, thus considerably reducing the cost of fixing these insulating elements.
  • the engagement part engaging in the material of the insulating plate makes it possible, by its configuration, to make invisible the anchoring element to be sealed according to the invention, after the assembly of the whole insulating layer.
  • the guide part according to the invention operating at a surface of the insulating plate, guarantees that the bearing face of the sealing part is always at the same distance from the surface of the glass wool. , distance corresponding to the concrete covering required. Indeed, a core connects the guide part to the sealing part.
  • the sealing part together with the guide part, may, for example, have the shape of a transversely coated U, the long wing of the transversely coated U, placed on the surface of the mineral wool insulating plate, forming the part guide and the upper wing, generally shorter, forming part of the sealing part.
  • the sealing part has a bearing face for the reinforcement on its side opposite to the guide part.
  • Such a bearing face is, in the simplest case, a flat face parallel to the surface of the insulating layer, but if necessary, it can also be adapted to the shape of the reinforcing elements.
  • a bearing face is, in the simplest case, a flat face parallel to the surface of the insulating layer, but if necessary, it can also be adapted to the shape of the reinforcing elements.
  • concave surfaces intended to receive the mesh of conventional steel reinforcement, so that, during the fitting of the reinforcement, one can avoid a sliding of this reinforcement on the bearing face .
  • the engagement part extends on both sides of the core. So we are ensured that two insulating plates can be connected to each other, end to end and can be fixed in place. This is made possible by the fact, in particular that an insulating plate is first placed on an external formwork, then a sealing anchoring element according to the invention is applied to the insulating plate by bringing its part into contact guiding with the face opposite to the visible side of the insulating plate; the engagement part is pressed into an end face of a mineral wool insulating plate so that a corresponding engagement part projects from the other side of the core of the anchoring element to sealing.
  • the following insulating plate is then moved on the external formwork towards this projecting engagement part, along the anchoring element with sealing, so that this part engages in the end face of the second insulating plate. and that, therefore, a butt joint barely noticeable by sight is obtained between the two insulating plates.
  • the anchoring element with sealing is a stamped piece of sheet metal, for example, of galvanized sheet steel.
  • a simple, flat manufacturing method is thus obtained, so that the stamping flank can be folded along predefined lines to give the anchoring element for sealing ready for assembly.
  • the guide part protrudes from the engagement part situated on the same side, with respect to the core, as this guide part, in the position of engagement of the part of engagement. This provides secure guidance of the anchoring element to be sealed over the surface of the insulating element.
  • the anchoring element with sealing can advantageously be manufactured from a stamping flank when, according to a preferred form of the invention, it comprises tongues arranged in an alternating manner; these tabs can thus be folded alternately to the left and to the right with respect to the core between the engagement part and the guide part.
  • the tongues of the engagement part are advantageously of a flat shape, in order to guarantee a force of sufficient retention, in particular in materials such as mineral wool, without significantly damaging the insulating plate.
  • the bearing surface is adapted to the elementary geometry of the frame, in such a way that it corresponds at least to the distance separating two neighboring elements from the frame.
  • the longitudinal extension of the bearing face is chosen such that it corresponds at least to the length from the edge of the elementary square.
  • the reference 1 designates a stamping flank having the shape of a sheet metal part.
  • the stamping flank 1 has tongues 2 on the right side in FIG. 1.
  • the stamping flank 1 is folded down at the level of the line indicated in a, perpendicular to the surface of stamping flank 1 delimited by lines a and b, then it is folded along line b, in the same direction, and along line c, perpendicularly upwards with respect to the surface of stamping flank 1 delimited by lines b and c.
  • the tongues 2 are folded along the line alternately to the left and to the right so that they occupy a position parallel to the surface delimited by the lines b and c.
  • a sealing anchor element 3 thus produced is shown in perspective in FIG. 2.
  • Such a sealing anchor element 3 comprises, in its lower part 4, an engagement part 5 which extends on both sides of a core 6 in the form of tongues of flat shape 2.
  • the core 6 connects the engaging part 5, on the upper side 7 of the core 6 opposite the engaging part 5, to a flat guide part 8, this guide part 8 being disposed at approximately 90 ° relative to the core 6.
  • the anchoring element with sealing 3 has a sealing part 10.
  • the sealing part 10 has a bearing face 11 which is arranged parallel to the guide part 8 and which is connected thereto by a spacer 12.
  • the distance s separating the bearing face 11 from the guide part 8 is, in this example, 15 mm and thus corresponds to the minimum distance necessary between a reinforcement and the concrete surface for the construction of a reinforced concrete ceiling.
  • a sealing anchor element 3 is illustrated in the mounting position for concreting the insulating elements 13.
  • the insulating elements 13 comprise a plate 14 of mineral wool made coherent by a binder.
  • On their lower face 15 is disposed a layer of light concrete 16 which is covered with a removable protective film 17 of polyethylene, intended to offer protection against soiling, for example with concrete milk.
  • the guide portion 8 protrudes, in the engagement position of the engagement portion 5, from the area of the engagement portion 5 which is provided on the same side of the core 6 as the guide part 8, because, thanks to this configuration, easy and safe guiding of the anchoring element with seal 3 on the surface 20 of the insulating element 13 is guaranteed.
  • a second insulating element 13 placed on the right in FIG. 3 is then brought by its end face 23 towards the tongues 2 of the engagement part 5 directed towards the end face 23, the two insulating elements 13 thus enclosing the anchoring element with sealing 3 in their joint, so that the anchoring element with sealing 3 is thereafter no longer visible from the side of a ceiling thus insulated, offered to view.
  • a steel mesh reinforcement 24 for reinforced concrete is placed on the bearing faces 11 of the anchoring elements with sealing 3, such so that it is maintained at a predefined distance s, in the case of this embodiment, of 15 mm, from the surface 20 of the insulating element 13, which corresponds to the building regulations.
  • the insulating elements 13 are covered with concrete. This state is illustrated in FIG. 4.
  • the concrete infiltrates in this case in particular, between the bearing face 11 and the guide part 8, so that after the concrete 25 has hardened, the sealing part 10 of the anchoring element with sealing 3 is firmly integrated in the concrete slab 26.
  • the insulating elements 13, after removal of the external formwork 19 remain in the ceiling of the building, as lost formwork, and are solidly anchored there. .
  • the protective film 17 is removed, so that an insulating layer having a visible face satisfactory to the view is available.
  • Figure 5 is a fragmentary perspective view of a formwork ceiling tile 26. This figure also shows that it is preferable for the transverse bars 27 of the steel mesh reinforcement 24 to bear on the bearing faces 11 sealing anchor elements 3, so that the bearing faces 11 sealing anchor elements 3 are arranged, in the mounting position, substantially perpendicular to the transverse bars 27 of the steel mesh frame 24.
  • the anchoring element with sealing 3 opens a possibility of concreting insulated elements 13 in a safe manner, and serves, at the same time, as a support for a frame 24, so that it is possible to dispense with auxiliaries additional support for the steel mesh frame 24.
