Definitions

  • the invention relates to a method for producing hollow bodies and to an apparatus for producing these hollow bodies by this method.
  • the demand for raw materials is growing rapidly in modern industrial society.
  • the stocks of natural resources are constantly becoming scarcer.
  • the result is either the need to search for alternative, artificial materials or to use the resources available more sparingly.
  • the material wood represents a raw material, which is indeed renewable, whose stock is already significantly reduced by the increasing demand today. Therefore, there is an increasing search for ways to make better use of wood stocks.
  • the full utilization of a tree trunk is already realized, until then, that from the chips pressed composite panels are produced, which are used for example in the furniture industry.
  • more and more attempts to process full logs more, but use glued beams or boards of single elements or produce hollow body of Einzelemeneten which also have the advantage of a large design variance and usually also higher strength values than grown logs.
  • the hollow body consists of prefabricated, elongated individual elements whose trapezoidal cross-section each forms a segment of the finished hollow body. At each individual element, two connecting surfaces for attachment of the individual elements to each other are present.
  • the bonding surfaces are successively coated with adhesive and then set together until the adhesive has set.
  • This known method is quite complicated and time consuming.
  • a stage plan of the production of a hollow body is shown by a method according to the invention.
  • a device is used in which the method can be used.
  • a generally pivotable turning frame (6) can be seen, consisting of a straightening frame (7) and an adjustable distance via at least one hinge (8) with the straightening frame (7) connected to the swing frame (9).
  • a plurality of mutually parallel spacers (12) are displaceable in the directional frame (7) transversely to their longitudinal direction, but can be aretted in any position. This is done via a rail guide, which serve to define fittings (21).
  • the spacers (12) are aligned with the center distance of the connecting surfaces (3, 4), so that they engage in an approximately triangular free space formed between two individual elements of the connecting surfaces (3 and 4).
  • the straightening frame (7) has at least two adjusting flanges (10, 11) which are required for setting a fixed distance dimension within the straightening frame (7) and one lateral Form edge boundary for the adjacent individual elements (1).
  • the joint (8) between straightening frame (7) and swing frame (9) is in the present case designed as a hinge joint, the first leg (13) is directly connected to the straightening frame (7) and engages the second leg (14) in an adjusting device (15) , which in turn has a connection to the pivoting frame (9).
  • the adjusting device (15) consists in the present case of a bush (16) with an internal thread (17) into which an insert (18) can be screwed.
  • the insert for its part, has a thread (19) which runs in the opposite direction to the internal thread (17) and into which a limb (14) of the joint (8) can be screwed.
  • An engagement or engagement surface (20) for a tool or a lifting device is also provided on the insert.

Claims (9)

  1. Procédé de fabrication de corps creux, caractérisé par les étapes de procédé consistant à :
    - préfabriquer des éléments trapézoïdaux individuels (1), dont la section transversale forme respectivement un segment du corps creux fini (2), deux surfaces de liaison (3, 4) étant présentes sur chaque élément individuel (1) pour fixer les éléments individuels (1) entre eux,
    - placer les éléments individuels (1) l'un à côté de l'autre dans l'alignement de manière à obtenir une surface fermée approximativement en forme de plaque, formant la face externe de la pièce finie,
    - appliquer au moins une bande de ruban adhésif (5) sur cette surface,
    - retourner la structure, en imprégner les surfaces de liaison (3, 4) d'agents liants ou d'adhésif, et
    - enrouler les éléments individuels (1) jusqu'à obtenir un corps creux fermé (2) et consolider ensuite le corps creux à l'aide d'au moins une bande de ruban adhésif.
  2. Procédé de fabrication de corps creux selon la revendication 1, caractérisé en ce que l'on utilise au moins une extrémité saillante de la au moins une bande de ruban adhésif (5) employée pour fabriquer la structure en forme de plaque pour consolider le corps creux fermé (2).
  3. Procédé de fabrication de corps creux selon la revendication 1 ou 2, caractérisé en ce que l'on retire les bandes de ruban adhésif (5) après séchage de l'agent liant ou de l'adhésif.
  4. Dispositif pour fabriquer un corps creux en mettant en oeuvre un procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que le dispositif présente au moins un cadre réversible (6), pivotant dans son ensemble, qui est quant à lui constitué d'un cadre directionnel (7) et d'un cadre pivotant (9) relié au cadre directionnel (7) à distance réglable par au moins une articulation (8), dans lequel le cadre directionnel (7) présente au moins deux flancs d'ajustage (10, 11), dont au moins l'un est conçu mobile pour le réglage d'une mesure de distance fixe à l'intérieur du cadre directionnel (7).
  5. Dispositif selon la revendication 4, caractérisé en ce que le cadre directionnel (7) présente des écarteurs (12) susceptibles de s'aligner en fonction de la distance entre centres des surfaces de liaison (3, 4).
  6. Dispositif selon la revendication 4 ou 5, caractérisé en ce que le cadre directionnel (7) présente au moins un cadrage pour régler les dimensions relatives à la pièce.
  7. Dispositif selon l'une quelconque des revendications 4 à 6, caractérisé en ce que l'articulation (8) entre le cadre directionnel (7) et le cadre pivotant (9) est une articulation à charnière, dont la première branche (13) est reliée directement au cadre directionnel (7) et dont la seconde branche (14) s'engage dans un dispositif de réglage (15), qui présente, pour sa part, une liaison avec le cadre pivotant (9).
  8. Dispositif selon la revendication 7, caractérisé en ce que le dispositif de réglage (15) présente un dispositif de levage entraîné par voie mécanique, hydraulique, pneumatique ou électromagnétique.
  9. Dispositif selon la revendication 8, caractérisé en ce que le dispositif de réglage (15) présente une douille (16) avec un filet intérieur (17), dans lequel on peut visser une pièce rapportée (18), laquelle pièce rapportée présente un filet d'usage courant (19) opposé au filet intérieur (17) et qui peut être vissé sur une branche (14) de l'articulation (8), et sur laquelle pièce rapportée se trouve, en outre, une surface de prise ou d'attaque (20) pour un outil ou le dispositif de levage.
