Definitions

  • the present utility model patent refers to constructive arrangements introduced in panel, which deals with core constituted of a sequence of wood veneer strips, fixed in oblique direction, vertically and in parallel to the length of the inner surface of a rectangular wood veneer, in order to constitute a panel susceptible of industrial application, and that will be used simultaneously as core and back face in the formation of wooden floors and of other materials.
  • core constituted of a sequence of wood veneer strips, fixed in oblique direction, vertically and in parallel to the length of the inner surface of a rectangular wood veneer, in order to constitute a panel susceptible of industrial application, and that will be used simultaneously as core and back face in the formation of wooden floors and of other materials.
  • particleboard core manufactured by using wood chips glued under pressure -
  • the core internationally known as H.D.F. [High Density Fiberboard] - manufactured with wood fibers and glued under high pressure -, or with flat plywood core made of wood veneer, or with core of solid lumber lath of approximately one inch of width.
  • this core presents a deficiency relative to the milling of the tongue in the one end of the panel, this is because the mentioned solid lumber laths are disposed horizontally and in parallel in the construction of this core, where it is noted that after milling the elaborated tongue is treated with a jut of approximately 5 mm of length by approximately 5 mm of thickness, observing that in front of the longitudinal direction of the laths, the longitudinal wood grains become very fragile due to the stress to which they are submitted.
  • the manufacturer is obligated to place in the one end of the panel, instead of solid lumber laths, a strip of plywood of the same thickness and size as a lath.
  • This plywood strip is disposed in the end of the last lumber lath, where it is noted that the plywood strip is formed by longitudinal and transversal sections, which gives sufficient resistance for the integrity of the tongue, however the plywood's density is never equal to the solid lumber's density. Obviously, the demand of such complementary constructive aspects contributes to raise even more the final cost of the product.
  • each strip is formed by the union of fillets of wood veneers with approximately 3 mm of thickness each fillet, which are glued to each other with waterproof phenolic glue, while the strips are fixed by gluing in oblique direction, vertically and in parallel along the inner surface of a rectangular wood back face veneer, where the assembly is dried at more or less eight percent humidity, and in the sequence, it is closed in a plastic packaging.
  • the panel object of this patent upon being unpacked, permits the absorption of up to twice the initial humidity without harming the conventional fitting of the tongue and groove.
  • the panel object of the present patent provides the sufficient resistance for milling or elaboration of the tongue to be done, which has perfect structuring to support the stress to which it will be submitted, where the conventional use of the plywood strip will not be needed, and its density will remain uniform.
  • the panel object of the present patent presents structural and functional advantages and can be elaborated with less wood waste and at lower cost, with relation to the best one in the market, noticing particularly that existing interstices or symmetric crevices between the strips of wood veneer, are responsible for an effect of flexibility, where this does not exist in the tackled material in the report of the state of the technique .
  • Figure 1 which shows in top view the core constituted by sequence of strips of wood veneers fixed in oblique direction, along the inner surface of a rectangular wood veneer.
  • Figure 2. which shows in top view the rectangular wood veneer of the panel intended for formation of floors.
  • Figure 3. which shows in side view the panel intended for formation of floors, evidencing the core constituted by sequence of strips of wood veneer fixed in oblique direction, along the inner surface of the rectangular wood veneer.
  • Figure 4. which shows in perspective the panel intended for the formation of floors, seeing in detail in circle that makes evident the interstice or symmetric crevice of separation between two strips of wood veneers.
  • the arrangements introduced in panel intended for the formation of floors include core constituted by sequence of strips ( 1 ) of wood veneers, where each strip ( 1 ) is formed by the union of fillets ( 1-A ) of wood veneers with approximately 3 mm of thickness each fillet ( 1-A ), which are glued to each other with waterproof phenolic glue, while the strips ( 1 ) are fixed by gluing in oblique direction, vertically and in parallel along the inner surface of the a rectangular wood veneer ( 2 ) or back face, making evident between the strips ( 1 ) interstices or symmetric crevices ( 3 ) responsible for the effect of flexibility.
  • the core constituted by the sequence of strips ( 1 ) of wood veneers, will receive afterwards a conventional top layer of noble wood or of other materials, which may have diverse thicknesses and sizes, occurring then the sanding and the milling of the tongue and groove at the four edges, thus forming the floor itself.

Abstract

L'invention concerne des agencements introduits dans un panneau destiné à la formation de planchers, utilisé simultanément comme face centrale et face arrière dans la formation de parquets et analogues, sur lequel est ensuite déposée une couche supérieure de bois noble classique ou autre matériau pouvant présenter des épaisseurs et des tailles diverses, obtenus par le polissage et l'usinage des langues et rainures sur les quatre bords. Le panneau selon l'invention comprend une séquence de baguettes de bois de placage (1) en pulpe, chaque baguette (1) étant obtenue par la fusion de filets de bois de placage (1-A), chaque filet présentant une épaisseur d'environ 3 mm. Les filets sont collés les uns aux autres au moyen d'un adhésif phénolique résistant à l'eau et les baguettes (1) sont fixées dans le sens oblique, verticalement et en parallèle le long de la surface intérieure d'une feuille de placage (2) ou face arrière rectangulaire. Entre les baguettes (1), apparaissent des interstices ou des sillons de flexibilité symétriques (3).
