FR2790021A1 - Massive wooden beams for construction of walls of house are laid horizontally one on top of the other, and have vertical splits filled with insulating material - Google Patents

Abstract

The beams (1) may be cut from logs to a square or rectangular section. They also may have interdigitating tongue-and-groove shapes in their top (4) and bottom (5) surfaces. The vertical splits (3) in each beam have tapered ends and are filled with thermal insulating material (2), and open up onto the top and bottom surfaces. There may be two splits end-to-end in each beam. More elaborate arrangements may be used, with several slits filed with insulation, side-by-side.

Description

The present invention relates to the field of the realization of

  buildings and more particularly buildings with exterior and / or interior wooden beam walls. Reference will be made below to chalets, but it should be understood that the invention relates to all wooden houses with exterior walls and / or

  interiors with wooden beams.

  The walls of the chalets are traditionally made by superimposing 0o wooden beams with a round, rectangular or square section depending on their

longitudinal direction.

  The present invention relates to a construction beam for the preparation of a vertical chalet wall by superimposing beams according to their

  longitudinal direction, of the type comprising one or more insulating elements.

  Since solid wood has poor insulation capacities, it is known to

  provide structural beams with insulating elements.

  The prior art knows for example the international patent application N WO 81 I 00585 which presents a construction beam formed by two parallel wooden beams assembled by an insulating spacer in foam of

polyurethane.

  According to this document, the insulation also has the function of ensuring the connection

between the two wooden faces.

  The prior art also knows the French patent application N 2 524 523 which relates to a building element constituted by two longitudinal wooden blades joined together by a series of metal transverse bars intended to reinforce the mechanical qualities of the beams, the volume rectangular between the two blades being filled with a cellular insulating material. In these documents, the thickness of the insulating layer is very large compared to the thickness of the wooden faces, in an attempt to have the best possible insulation, but in use, there is a problem on the one hand of cohesion between the insulating materials and the exterior materials and on the other hand of mechanical strength because the mechanical qualities of the assembly obtained are much lower than those of

solid wood beams.

  To overcome these drawbacks, the present invention proposes to make the solid wood construction beams and to provide them with one or more vertical reservations made in a longitudinal direction in order to allow

  the insertion of one or more insulating elements.

  An important object of the invention is to allow the construction of solid wood construction beams in which are inserted insulating elements, so as to improve the insulation of the walls produced by the superimposition of beams so that these insulating elements form optimal insulation over the entire

  height and all along the wall.

  Advantageously, the beams according to the invention are provided with reservations made in several parallel longitudinal directions so that at i0 at least one reservation appears when a cross section of a beam is made. Another object of the invention is to allow the insertion of insulating elements

  either during the manufacture of the beams, or during the construction of the walls in beams.

  To do this, the invention recommends arranging the reservations so that they open onto the upper and lower horizontal surfaces of the beam and so that the locations of the reservations coincide as best as possible from beam to beam so as to be able to introduce the or said insulating elements on

  the entire height of said wall, after construction of said wall.

  The present invention has been developed using insulating elements of the aluminum foil type, but its implementation can be extended to all types of insulators, for example but not limited to: rock wool, glass wool,

synthetic material, etc ...

  The invention will be better understood with the aid of the description given below.

  the invention for purely explanatory purposes with reference to the appended figures in which: - Figure 1 illustrates the block diagram of the invention - Figures 2, 3, 4, and 5 illustrate different possible arrangements of reservations in the beams according to l 'invention; and,

  - Figures 6, 7 and 8 illustrate different beam profiles according to the invention.

  The present invention, illustrated in FIG. 1, consists of a construction beam (1) for the construction of a vertical wall by superposition of beams (1) in their longitudinal direction, of the type comprising one or more elements

insulators (2).

  It is characterized in that said beam (1) is made of solid wood and in that it comprises one or more vertical reservations (3) made according to a

  longitudinal direction for the insertion of said insulating element (s) (2).

  The reservations are in the form of slots, the width of which varies for example between 5 to 10 mm or more. These reservations can run all along the beam, as illustrated

  Figure 2 or intermittently, as shown in Figure 3.

  Preferably, said vertical reservations (3) are made in several parallel longitudinal directions, as illustrated in FIG. 4, so that at least one reservation (3) appears when a cut is made.

transverse of said beam (1).

  The best insulation is obtained by arranging the reservations in staggered rows, as illustrated in FIG. 5. In this version of the invention, when a cross section of the beam (1) is made, at least two are observed.

  reservations (3) into which insulating elements (2) are inserted.

  To insert the insulating elements (2) in the beam during manufacture, it is of course necessary to arrange the reservations (3) so that they open onto the upper horizontal surface (4) or onto the horizontal surface

lower (5) of the beam (1).

  According to a version of the invention, said reservations (3) lead both to the upper horizontal surface (4) and to the lower horizontal surface (5) of the beam (1), so as to be able to introduce the said insulating element (s) (2) over the entire height of said wall, after construction of said wall, that is to say

  on the site of the construction of the building.

  According to a preferred version of the invention, the construction beams (1) have a square section, as illustrated in fig 6, round, as illustrated in fig 7 or rectangular, as illustrated in fig 8 and they comprise one or more longitudinal rails (6) on their upper face (4) and one or more longitudinal recesses (7) on their lower face (5) in which or in which the rail (s) (6) of the beam (1) can be accommodated positioned just below for the

construction of said wall.

  Thus, during the elaboration of the wall by superposition of beams (1), the

  beams are easier to position.

  On these beams, the reservations can be positioned for example at

  level of rails (6) and recesses (7).

  In a preferred version of the invention, the said insulating element (s) (2) are of the aluminum foil type, but they can be replaced for any type

  insulation. Such an adaptation is within the reach of those skilled in the art.
