Definitions

  • the present invention relates to a construction element intended in particular for the manufacture of load-bearing walls or separation of a building, said building element having an increased thermal insulation capacity.
  • a wooden house has the disadvantage compared to a stone house to be less thermally insulated from the outside due to the high thermal conductivity of the wood panels used to form the load-bearing or separating walls of the house .
  • it is often necessary to add an additional insulating layer between the wooden panels and the interior of the house. This operation therefore increases the manufacturing cost and the manufacturing time of the house.
  • this operation is poorly executed, the thermal insulation of the house is still unsatisfactory compared to that of a stone house.
  • the present invention therefore aims to provide a construction element used in the manufacture of a wooden house and to solve the aforementioned problems.
  • the construction element thus configured advantageously has a reduced thermal conductivity compared to a simple wooden panel. Furthermore, it is no longer necessary to add an additional layer of thermal insulation between the building element and the building interior. In addition, because the insulation material fills all the empty space contained within the building element, the building element has increased rigidity. This increased rigidity considerably lighten the framework based on the building components constituting the low frame of the building, thereby reducing the cost and time of manufacture of the building.
  • This building element 10 comprises a wooden front panel 11 and a wooden back panel 12, said panels being arranged parallel to one another.
  • the separation space between said front panel 11 and said rear panel 12 is segmented into a series of contiguous housings 14 by means of a plurality of transverse panels 13 orthogonally disposed to said front and rear panels.
  • Said transverse panels 13 are advantageously connected at their side edges to the front and rear panels by means of a dovetail connection.
  • the lateral edges of each of the transverse panels 13 are provided with projecting shapes 16 intended to be inserted inside corresponding cavities 15 formed inside the front and rear panels.
  • the internal space of the housing 14 is also completely filled with an insulating material (not shown) so as to give the building element increased thermal insulation and increased rigidity.
  • This insulation material may in particular be chosen from expanded polyurethane foams, expanded foam castor resin and expanded foams based on soybean oil.
  • the insulation material will be injected under pressure into the housings 14 through one or more openings in the front or rear panel.
  • the vacuum it will also be possible to use the vacuum as an insulation material.
  • the front, rear and transverse panels may be impregnated with a liquid resin formed of an aqueous dispersion of a styrene-butadiene copolymer which will prevent gaseous transfer occurring between the interior of the housings 14 and outside.
  • transverse panels 13 may advantageously be provided with through holes 17, each of the through holes communicating the internal space of two adjoining housing. As discussed in detail in the following paragraphs, these holes-provided panels 13 will have less thermal conductivity than a solid wood panel, which will, as a result, increase the thermal insulation power of the building element. 10 as a whole.
  • the transverse panels 13a are wood panels without holes having a width of 26 mm, a height of 515 mm and a thickness of 27 mm, said transverse panels being regularly spaced along the front and rear panels, the space between two adjacent transverse panels being equal to 60 cm.
  • the front and back panels are also unpainted wood panels with a height of 515 mm and a thickness of 27 mm.
  • a polyurethane foam having a thermal conductivity ⁇ i of 0.021 W / (mK).
  • the variant of the figure 2b differs from that of the figure 2a by the use of transverse panels 13b provided with five through holes 17b having a diameter of 60 mm, the width of the panels 13b being equal to 96 mm.
  • the thermal conductivity ⁇ pt of each of the transverse panels and the heat transfer coefficient U ec1 of the construction element are then successively calculated.
  • the heat transfer coefficient U ec0 of a component identical to that shown in FIG. figure 2b apart from the fact that all of its transverse panels are full instead of having holes. The results obtained are listed in Table 1 below.
  • the variant of the Figure 2c differs from that of the figure 2a by the use of transverse panels 13c provided with three through holes 17c having a diameter of 100 mm, the width of the panels 13c being equal to 146 mm and the variant of the figure 2d differs from that of the figure 2a by the use of transverse panels 13d provided with 11 through holes 17d having a diameter of 60 mm, the width of the panels 13d being equal to 196 mm.
  • Table 1 also indicates for each of the variants the surface ratio Rs between the total surface of the holes of each of the transverse panels and the total surface of each of the transverse panels.
  • Table 1 ⁇ / u> ⁇ pt (in W / (mK) U ec0 (in W / (m2K) U ec1 (in W / (m2K) RS (in%)

  • Variant Figure 2c 0069 0155 0143
  • Variant Fig.2d 0077 0115 0106 31
  • transverse panels with holes (variant of Fig. 2b, 2c and 2d ) have a significantly lower thermal conductivity than the transverse panels without holes of the variant of the Fig. 2a .
  • the use of transverse panels provided with holes improves the thermal insulating power of the building elements as a whole.
