Definitions

  • the drilling is carried out before drying and stabilization of the wood since it is precisely a means of rapidly obtaining these states of matter.
  • a ready-to-use element offers, at least at one of its ends, a hole which is no longer neither perfectly circular, nor centered, nor even exactly rectilinear on a certain length.
  • the passage internally absorbs the deformations which without it would have carried over to the outside.
  • the present invention fully respects all the qualities of the wooden elements having a central passage and allows them to be used without suffering any of the drawbacks that the presence of holes at the ends of these elements may present.
  • the invention relates to a process for the shaping of wooden elements such as beams, trunks and tree segments having a longitudinal passage over their entire length and thus having two ends each having a hole, characterized in what we report a piece of wood to at least one of the ends of an element by engaging it in the existing hole, piece of wood which has the same section as that of said hole in order to close it, then that said part is shaped to make it suitable for constituting an assembly member.
  • the invention also relates to a wooden element such as cleat, beam, trunk and segment of tree, having a longitudinal passage over its entire length and thus originally having two ends each having a hole, characterized in that 'It has at least one solid end resulting from the addition of material closing off the original hole.
  • Figure 1 is a schematic sectional view of a pierced wooden beam of known type.
  • Figure 2 is a schematic sectional view of the beam of Figure 1, ready to receive parts for its shaping.
  • FIG. 3 is a schematic front view of the beam of FIG. 1.
  • Figure 4 is a schematic front view of a beam prepared according to the invention.
  • Figure 5 is a schematic front view of the beam of Figure 4, after digging a housing.
  • Figures 6 and 7 are two partial schematic perspective views of elements according to the invention and having respectively male and female assembly members.
  • FIGS 8, 9 and 10 are schematic views showing three possible variants for shaping the ends of elements according to the invention.
  • Figures 11, 12 and 13 are schematic views showing the shaping of the ends of elements according to the invention, according to three different angular arrangements.
  • Figure 14 is a schematic view illustrating various possibilities of simple assembly of elements according to the invention.
  • Figure 15 is a schematic view of a building wall made with elements according to the invention.
  • Figure 16 is a partial schematic view of an assembly according to the invention, constituted by assembling segments, which can be prefabricated.
  • Figure 17 is a partial schematic view illustrating an alternative embodiment of the invention.
  • the hole B is made in particular to facilitate the drying of the wood, in order to prevent the beam from twisting or deteriorating by cracking.
  • the wood therefore works after drilling and it is often found, in practice, that the hole B is irregular: it may have the defect be off-center, or the defect to be deformed, or the defect to be irregular or the three defects to that time.
  • the longitudinal drilling has advantages, it has the disadvantage of creating voids at the ends which make it impossible to shape said ends while it is a long tradition to provide recesses such as tenon and mortise, miter cuts and others.
  • full ends are reconstituted over a short distance by comparison with the length of the hole and, to this end, an element A already pierced with its hole B is taken, then one engages, at the two mouths of hole B, parts 1 and 2, the external dimensions of which are coordinated with those of hole B as they appear at the two ends of element A, it being recalled that the irregularities of hole B may be different at the two ends of the same element A It is to illustrate this that two unequal parts 1 and 2 have been shown.
  • the parts 1 and 2 can be simply engaged by force or else be fixed by gluing or by means of attached members such as screws.
  • FIG. 3 shows an eccentric hole B as the dimensions v and w highlight it and FIG. 4 shows the same element after plugging of the existing hole B by a piece 1 put into force, without prior correction of the hole B.
  • the housing 3 can be perfectly centered, as indicated by the line which evokes the center common to the element and to the housing 3. It can also be completely circular and very regular, the accuracy depends mainly on the quality of the material from which parts 1 and 2 are made, as well as the tools used.
  • FIG. 6 shows a male part (or "tongue") 4 cut in part 2, at the nominal diameter of the latter but it is understood that one could have, without difficulty, given the tongue 4 a height equal to that of the beam, as indicated in dotted line, either by cutting the tongue and the part 2 in one piece, or by providing the parts 4 a and 4 b on the beam A itself.
  • tongue or "tongue”
  • FIG. 7 shows a female part (or "mortise”) 5 cut both in the beam A and in the part 1 since it must open at least into the upper part of the beam A.
  • the parts 1 and 2 each have a housing 3 with an axis parallel to the longitudinal axis of the element A since, in this case, these two axes are the same.
  • These housings are intended for the assembly of elements either with other similar elements, or with a frame or other part of construction.
  • parts 1 and 2 makes it possible to work these ends 11 and 12 at leisure: planing, sanding, etc., all things impossible on ends pierced with a free hole.
  • FIG 9 there is shown an element A whose ends 13 and 14 are cut at a 45 ° miter and it is noted that the housings 3 have axes not parallel to the longitudinal axis of element A and not parallel to each other since each is normal to the plane of the corresponding face.
  • these housings are intended for the assembly of the element and must therefore be present perpendicular to the plane of the corresponding end.
  • an element A has an end 13 with a mitered end and an end 12 perpendicular to the longitudinal axis of the element A.
  • Figures 11, 12 and 13 show elements A whose ends are mitered at different common angles: 60 °, 45 ° and 30 °, which allows you to choose the most appropriate element A to join two virtual planes ⁇ and ⁇ which could be amounts of a frame for example.
  • the housings 3 have their axis perpendicular to the plane of the corresponding end.
  • FIG. 14 illustrates several assembly possibilities for producing an assembly from drilled wooden elements.
  • the housings 3 can be simple blind holes or consist of plastic bowls fixed by any known means such as glue in blind holes.
  • junction piece 6 of the cylindrical tenon type is placed at this location, and it is fixed there.
  • the fixing can be obtained by means of glue, screws, lag bolts or, as shown, nails 7.
  • the fixing of the element A can be done by gluing the connecting piece 6 in the housing 3 or by means of traditional dowels 8 which pass through both the element A and the connecting piece 6, provided that the nails 7 do not oppose it, in particular because they are absent and replaced by a bonding.
  • FIG. 15 illustrates a wall produced with elements A constituting half-timberings which determine spaces for bricks, according to a traditional construction method in many countries.
  • FIG. 16 represents an embodiment of the invention according to which elements A are assembled in the workshop to constitute assemblies having their own characteristics.
  • such an assembly can consist of two parallel main beams 21 and 22, braced by oblique elements of smaller section 23 and 24.
  • This structure is similar to that of lattice beams and can, of course, be produced according to many variants, in particular according to a triangulation conducive to a high strength / weight ratio.
  • the ends of the oblique elements 23 and 24 must be able to be joined to the main beams 21 and 22. To this end, it is possible to provide housings 3 at each of these ends and at the desired locations of the main beams 21 and 22. In the housing 3 of oblique elements 23 and 24 or in that of the main beams 23 and 24, a tenon 9 is placed, forcibly engaged and / or glued.
  • This set can be prefabricated in the workshop or made on site.
  • the invention also makes it possible to constitute assemblies to assemble oneself, or "kits”, comprising a certain number of elements of drilled wood, cut and cut in a precise manner, so that a buyer can achieve a structure with the minimum of work, which presupposes, for example, that the assembly sold includes all the desired assembly members (connecting pieces 6, nails 7, dowels 8, glue, etc.).
  • Junction pieces 6 can be solid, hollow (like sockets and fixed by their bottom), with a grooved wall to facilitate bonding, in wood, synthetic material, metal, etc.
  • FIG. 17 illustrates a feature of the invention according to which a part 1 can be placed in the axis of the hole B to close it and reconstitute a solid wood end, but according to which one can also provide parts 10 whose diameter corresponds to that of hole B and which are engaged in radial holes which pass through the wood of the element A up to and beyond hole B over a certain thickness.
  • the part 10 closes the hole B as well as a part 1 axially engaged and allows, in addition, lateral assemblies.
