Definitions

  • the present invention relates to a method for applying a coating to a substrate, such as sheets or steel walls.
  • the invention also relates to a device used in the implementation of this method. Finally, it relates to a reinforced coating obtained from this process.
  • This reinforcement usually consists of a wire mesh which consolidates the coating and thus prevents it from leaving the substrate.
  • the reinforcement is located approximately half the thickness of the coating to consolidate it most effectively.
  • the object of the present invention is to provide a method for applying a coating to a substrate which overcomes the above drawbacks to obtain a robust coating which is fixed securely to the substrate.
  • this method is characterized in that the attachment devices comprise hooks formed by a rod, for example metallic, curved substantially in the shape of a U and in that these hooks are fixed to the substrate by one branches of the U, for example by welding or gluing or screwing.
  • the hanging devices are preferably uniformly distributed thereon, but if the substrate has fold lines or strong curvatures, the density of the hanging devices may be higher in the vicinity of these. parts.
  • the attachment devices are substantially flat hooks which are fixed on the substrate with variable orientations and / or inclinations (for example upright or lying).
  • the hooks are fixed to the substrate at a point on a branch of their substantially U-shaped shape chosen as a function of the desired spacing between the substrate and the frame. Thanks to this arrangement of hooks, it is possible to control the spacing between the substrate and the frame and therefore use identical hooks to deposit coatings reinforced with different thicknesses.
  • the reinforcement has a corrugated arrangement which keeps it firmly on the substrate and also provides maximum reinforcement for coatings of significant thickness.
  • Another aspect of the invention relates to a device which can be fixed on a substrate to maintain an armature therein in accordance with the above method.
  • this device comprises a hook formed by a curved rod substantially in the form of a U, one of the branches of which has a curvature opposite to the curvature of the base of the substantially U-shaped.
  • the invention also relates to a coating applied to a substrate in accordance with the above method.
  • This coating thus comprises an armature embedded in the coating, the armature being inserted in attachment devices fixed to the substrate in preferably variable positions relative to the substrate.
  • a coating 10 on a substrate 1 for example a steel wall
  • the coating 10 in question having to be reinforced, that is to say reinforced by a reinforcement 2 in the form of a wire mesh or the like.
  • a reinforcement 2 in the form of a wire mesh or the like.
  • Several types of coating thus fall within the scope of the invention, for example fire-resistant, anti-humidity, thermal insulating, ornamental or other coatings.
  • a fire-resistant coating 10 applied to a metallic substrate 1 forming part of a construction work we choose the particular example of a fire-resistant coating 10 applied to a metallic substrate 1 forming part of a construction work.
  • the substance constituting an example of such a fire-resistant coating is described in patent FR-A-2,458,519 to the applicant. This substance is designed to offer a certain resistance to heating, especially in the event of fire.
  • FIG. 1 a metal substrate 1 is shown on which the framework 2 has been placed in the form of a wire mesh before the application of the coating 10.
  • Strands of the frame 2 are inserted, if necessary after deformation, in hooks 3 fixed on the substrate 1 to hold the frame 2 on the substrate 1.
  • These hooks 3 have an identical determined structure and each constitute individual attachment means. They are fixed spaced apart on the substrate 1 in different positions relative to the substrate 1.
  • the structure of the hooks 3 used is illustrated in FIG. 3.
  • the hook 3 comprises a curved metal rod in the shape of a U with a rounded base, the two branches 5 and 4 of which have a curvature of the same direction and of opposite direction to the curvature of the base of the U.
  • the hooks 3 can also be coated in a plastic sheathing, in particular if they are intended to be in contact with a very acidic coating. These hooks can also be made of rigid synthetic material, or even of ceramic. In these two cases, their attachment to the substrate is advantageously carried out by gluing or screwing in preformed tapped holes.
  • FIGS. 1 and 2 It can be seen in FIGS. 1 and 2 that the supposed metal hooks 3 are welded to the substrate 1 at a point on the branch 5 of their U shape having a curvature in the same direction as the base of the U.
  • the position of this fixing point along the branch 5 is chosen as a function of the desired spacing between the substrate 1 and the frame 2 inserted in the hook 3.
  • certain hooks 3 can be welded by a welding point 6 situated in the vicinity of the end of the branch 5, which gives rise to a relatively large spacing e between the substrate 1 and the armature 2 inserted , favorable to the application of a thick coating 10 while other hooks 3 can be welded at a point closer to the base of the U (FIG. 5), resulting in a smaller spacing e ′ between the substrate 1 and the reinforcement 2 inserted, preferred for the application of a thinner coating 10.
  • hooks 3 can advantageously be used to apply coatings of different thicknesses, typically from 5 mm to several centimeters.
  • the dimensions of the hooks 3 can be chosen as a function of the desired spacing between the substrate 1 and the frame 2.
  • FIG. 1 it can also be seen that certain hooks 3 have different orientations when they are fixed to the substrate 1. More precisely, the plane defined by the substantially U-shaped structure of the hooks 3 has a variable orientation relative to the defined plane by the substrate 1.
  • the variable orientation can be a variable tilt or a variable azimuth. This random orientation of the hooks 3 prevents any skidding of the frame 2 parallel to the substrate 1 during the application of the coating.
  • the frame 2 may come off the hooks 3 by passing under their free branches 4. This is prevented by the arrangement of the hooks 3 with variable orientation, preferably random.
  • the coating 10 is applied to the substrate 1 carrying the frame 2 held by the hook devices 3.
  • FIG. 2 there is symbolically shown a pipe 8 for distributing under pressure the material forming the coating 10.
  • the method of applying the material constituting the fire-resistant coating 10 is described in detail in patent FR-A-2 458 519 to the plaintiff, cited here for reference. It can be seen, in FIG. 2, that the coating 10 formed can have different thicknesses depending on the distance e, e ′ between the substrate 1 and the frame 2 thanks to the variable positions that the hooks 3 can take.
  • the frame 2 is placed about half the thickness of the covering 10.
  • the hooks 3 are arranged alternately on the substrate 1 so as to produce an undulation of the frame 2.
  • This undulation strengthens the retention of the frame on the substrate and is suitable for consolidating a thick coating, which is generally not possible with conventional reinforced coating techniques.
  • the alternate arrangement of the hooks is not the only one allowing this variable spacing between the substrate 1 and the frame 2, the main thing being to mount certain hooks 3 so as to achieve a relatively small spacing e ′ (FIG. 5) and others so as to achieve a relatively large spacing e (FIG. 4).
  • the frame 2 can be inserted into the hooks 3 before or after their attachment to the substrate 1 according to the preferences of the technician.
  • a frame 2 in the form of a wire mesh is only a non-limiting example of a frame usable in the context of the invention. It is naturally possible to use any known frame allowing insertion into the attachment devices, for example an openwork sheet or the like, or even a frame made of synthetic material.
