Definitions

  • the present invention relates to a structural element in the form of a beam or a panel comprising an assembly of longitudinal walls and spacers, intended for the erection of a residential or office wall.
  • the document FR 3,022,569 discloses a beam comprising two longitudinal and parallel side walls and an inner wall, defining internal spaces in which are located a series of spacers and insulation elements. These spacers are arranged perpendicularly to the longitudinal walls. The spacers of a first space between a side wall and the inner wall are offset from those located in the second space between the other side wall and the inner wall. These spacers are regularly distributed, while a spacer of the first space is located at half the spacing of two spacers arranged in the second space.
  • These beams are manufactured by pressing the longitudinal walls, glued in contact with the spacers and insulating elements.
  • This regular structure of the spacers generates a longitudinal wave effect of the resulting beam, during assembly in press.
  • This disadvantage is overcome in part by the use of insulation elements having a low compression ratio.
  • the presence of these compact insulation elements attenuates the longitudinal deformations due to the pressing, contributing to transmit the pressing forces.
  • this beam structure is limited to insulators having a low compression ratio.
  • beams formed of wood veneer are assembled under a pressure of 8 bar / cm 2 .
  • the previously described beams are commonly assembled under a pressure between 2 and 2.5 bar / cm 2 . Pressing these beams to a higher pressure, even in the presence of insulation with a low compression ratio, causes permanent longitudinal deformation.
  • fibrous insulation elements which are in general extremely compressible. Many materials having a high compression ratio, have excellent performance, in particular in terms of thermal conductivity, it would be wise to integrate them in a beam structure with multiple compartments.
  • the present invention provides a beam or a panel, to overcome the aforementioned drawbacks.
