Definitions

  • the invention relates to a profile of round or sawn timber and a method for its production.
  • the method enables the cost-effective production of technical profiles, such as box and pipe profiles made of wood.
  • Wood is a material with a high pore volume fraction and consists essentially of cellulose and lignin. While the cellulose forms the skeleton, the lignin has a firming and sticking function. At temperatures above 100 ° C., lignin softening occurs and thus plastification of the wood, especially transversely to the fiber direction. This makes it possible to compact wood across the grain at relatively low pressure. Methods for plasticizing wood by heating are known.
  • the softening of the wood is usually achieved by contact heating or by Hochfrequenzplastization in the range of 100 0 C to 160 0 C. Also a treatment with chemicals improves the malleability of the wood. Methods for compacting wood are already known. The aim of these processes is an improvement of certain wood properties, such as increasing the E-modulus, increasing the hardness, increasing the strength, but also improving the wood protection.
  • the method is therefore very time-consuming and energy-consuming to assess, since both the compaction, as well as the bending much energy for the plasticization of the wood is needed.
  • the two-time wood drying is very time and energy consuming.
  • Another significant disadvantage is that a large part of the compaction and thus also a part of the obtained wood coating, such as increasing the E-module, increasing the strength and the hardness of the wood must be sacrificed during the process due to the bending.
  • the present method overcomes all of these disadvantages.
  • the object of the invention is to produce high-quality profiles by an economical method of inferior wood. It is juice-fresh or undried wood to process. A complex sorting is not required. Wood drying, shaping, compaction and joining of the wood are carried out in parallel in a single operation, so that this is a very time and energy-saving process. The compaction and wood coating produced, such as increased modulus of elasticity, increased strength and hardness, are retained in the profile due to the process.
  • the profile can be round or
  • Sawn timber (thin wood from NH or LH) are produced, which is obtained inexpensively in the domestic forestry in large quantities.
  • the woods are arranged in a mold such that they form a closed and inherently stable circular ring (FIG. 1).
  • the contacting side surfaces of adjacent woods are previously provided with a binder as needed.
  • the woods are pressed together, in the plasticized state, by a press die through the mold.
  • the mold has a tapered round or oval cross-section. (eg bottle-shaped, Fig.2) This way, the woods are compressed perpendicular to the grain direction.
  • the woods are joined together under the influence of pressure and heat.
  • special press-in dowels between the individual woods. These are pressed by the resulting pressure between the individual woods in the wood surfaces.
  • the length of the compacted profile is variably executable and on the one hand on the individual length of round or lumber, on the other hand to realize an arrangement of staggered longitudinal joints between the individual round or cut lumber in the mold.
  • the woods may be treated with fungicides, fire retardants, resins or binders before or after shaping.
  • fungicides fungicides, fire retardants, resins or binders
  • After the production of the compacted profile it is possible to coat the lateral surface with a technical textile, e.g. Laminate glass fiber fabric.
  • Laminate glass fiber fabric e.g. Laminate glass fiber fabric.
  • Fig. 2 longitudinal section through the mold and the ram
  • Open profiles according to FIG. 4a) are produced by dispensing with the application of glue and / or press-in dowels between defined woods before compacting. After leaving the mold, the compacted profile disintegrates into the open profiles.
  • the closed profiles according to FIG. 4 c) and the open profiles according to FIG. 4 d) are produced by connecting open, compressed profiles according to FIG. 4 a) with profiles according to FIG. 4 b).

Abstract

La présente invention concerne un profilé en bois et un procédé de fabrication correspondant. Selon cette invention, les profilés peuvent être fabriqués à partir de bois en grume ou débité de tous les types de conifères et de feuillus. Des sections transversales de bois individuelles sont comprimées à l'état plastifié par une matrice de compression et sont reliées les unes aux autres. Le procédé selon cette invention permet d'améliorer des caractéristiques importantes du bois, telles que la résistance et le module d'élasticité. Les profilés selon cette invention présentent une plus grande charge admissible que des sections transversales en bois massif, avec le même volume de bois.
