Definitions

  • the invention relates to insulating supports for plaster and finds a particularly important application in the constitution of insulating complexes making it possible to reduce the heat exchanges through the walls of a building.
  • the invention also makes it possible to make constructions, by mounting the insulating supports between load-bearing structures before applying the coating.
  • an insulating panel is bonded to the substrate to be insulated which receives a patching compound in which a mesh is included. Then we spray a finishing plaster.
  • the implementation of this process is simple, but gives a heterogeneous layer modifying the gas exchanges of the substrate.
  • the present invention aims to provide attachment panels applicable to the constitution of thermal insulating complexes, responding better than those previously known to the requirements of practice, in particular in that it allows for high insulation, is implemented easy and of an acceptable cost price, and gives rise to corrosion-resistant complexes with very high adhesion of the coating to the support and to the substrate, thereby rendering the risks of cracking and delamination minimal.
  • the invention provides an insulating support plate for plaster, comprising a trellis core, provided on at least one face with plaster anchoring means, characterized in that in the core are formed at regular intervals through perforations for receiving insulating plaster for bonding the substrate and the support.
  • the perforations advantageously have a convergent-divergent shape from one face to the other to help the penetration of the coating during its projection and to improve the attachment to the support.
  • the volume of material of the insulating support represents at least two thirds of the total volume including the voids.
  • the core advantageously comprises, on the face intended to be fixed against the substrate to be insulated, anchoring means such as grooves around the perforations.
  • a mesh grid can be placed on the support plate to further increase the adhesion of the plaster. This will generally consist of a mixture of hydraulic binder, expanded plastic material and insulating mineral filler, as well as lightening additive.
  • the core will, as a rule, be made of expanded plastic material compatible with the coating.
  • the support plate will generally be delivered in panels of a size compatible with current means of transport and handling: in practice, we can envisage the manufacture of panels whose surface ranges from 0.25 to 4 m 2. To ensure appreciable isolation , the thickness of the core must be at least 50 mm. It is generally unnecessary to exceed a thickness of 200 mm.
  • the perforations will be distributed according to a regular network. We can consider a square mesh network, but it appeared preferable to use a triangular network in most cases.
  • the insulating complex 8 shown in FIG. 1 on a substrate 4 which will be assumed to be a building wall, either in restoration or in new work, comprises a support 1 made of insulating material, constituting a core.
  • perforations 5 which, in the embodiment of FIG. 1, have a bitronconical shape so as to converge from the two faces. This geometry is however not essential and other forms are possible, provided that good penetration of the coating and satisfactory connection of the coating with the substrate 4.
  • the face of the support 1 intended to bear against the substrate comprises means 3 for anchoring to the substrate, represented in the form of grooves.
  • the face of the support 1 intended to receive the plaster has plaster anchoring means adding to the perforations 5.
  • these anchoring means 2 are represented in the form of a cavity.
  • the thickness of the insulating support 1 and the dimension of the perforations may vary, in particular as a function of the insulation to be produced. In the case where the perforations are distributed along a triangular network, a spacing between adjacent perforations of the order of one and a half times the diameter of the hole gives satisfactory results. We will deviate from this value if we use another type of network, for example an octagonal network combined with a square network.
  • the insulating support 1 will generally be made by molding or shaping rigid or flexible, micro or macro-cellular heat-insulating materials, the proportion of closed cells of which is very high.
  • the mechanical resistance of the material must obviously be compatible with the binder used and the fire resistance criteria must meet the standards in force. Expanded polystyrene will generally be a good choice.
  • the support can be manufactured in the form of a rectangular panel, for example 0.50 m wide and 3 m long.
  • the support is coated with a grid 7, for example made of metal wire, intended to further increase the attachment.
  • the insulating mesh formed by the support 1 is then filled and covered, generally by spraying, with an insulating coating 6.
  • the converging shape of the perforations guides the coating and facilitates the filling of the perforations and good adhesion with the substrate. Still in the case indicated in FIG. 1, the amount of coating applied is sufficient to allow a protection thickness which may be from 2 to 6 cm to remain above the support 1 or the grid 7.
  • the mortar 6a may have one of any usual constitutions in construction, for example a poor mortar (at 120-350 kg per m 3 of binder) containing aggregates constituted by expanded polystyrene, insulating mineral fillers (for example stone- crushed pumice, dusted 1.5 to 3.5 mm or crushed raw perlite) and additives such as soluble silicas and air entrainers to lighten the mortar.
  • the finishing plaster 6b will be chosen according to the local conditions of use and to protect the internal part of the complex 8.
  • the manufacture of the insulating complex 8 is very simple: the insulating support panels 1 are first fixed to the substrate, for example by nailing or by gluing, possibly after stripping of the substrate as in the case of the installation of a traditional coating. .
  • a base can be provided to avoid lowering the insulating supports to the ground. The panels can be cut to make corner returns.
  • the mortar 6a is then sprayed, first in filling and then to form a thin layer covering the entire support 1. Locating pins 9 can be provided on the support 1 to allow easy equalization of the mortar 6a. Finishing plaster 6b is finally applied, in the traditional way.
  • FIG. 3 and 4 show more precisely a particularly advantageous shape of the perforations 5.
  • These perforations comprise a substantially cylindrical central zone 10 which is connected by a shoulder to a frustoconical zone 11 on the internal side.
  • the internal side anchoring means consist of annular grooves 3 surrounding the perforations.
  • the perforation comprises a frustoconical part 12 which is connected to a very flared part with flat sides 13. These flat sides 13 appear better in FIG. 5, which also shows the locations 14 for the action of release punches.
  • the support plates according to the invention can also be used to form a filling in load-bearing structures, in particular in prefabricated constructions.
  • the supports and the structural elements receive the heat-insulating coating on the outside and receive on the inside a finishing coating, such as plaster.
  • a coherent assembly is formed, ensuring high thermal and sound insulation, having satisfactory mechanical strength, and which, moreover, simultaneously makes it possible to obtain impermeability to high water projections and good diffusion of water vapor, due to the presence of the mortar in contact with the wall.
  • the multiplicity of plaster fixing points with the wall and the compatibility of the expansion coefficients also avoid the risks of cracking and delamination.
