Definitions

  • the present invention relates to a method for protecting laminated timber and glulam made of lamellas from decay according to the preamble of patent claim 1.
  • the lamellae generally have a thickness of 20 to 40 mm and are therefore not or only insufficiently penetrated by the active ingredients emanating from the glue joint.
  • Wood protection is particularly problematic for glued wood, which is exposed to the weather in whole or in part and is particularly at risk of decay due to the appropriate water absorption.
  • Wood components that are particularly at risk of decay include windows and external doors in the border area between indoor and outdoor climate.
  • the decay-inhibiting, water-soluble, diffusible substance is a pasty boron and / or fluorine compound with the property of decaying under the influence of moisture penetration of less than 20% wood moisture before the penetrating moisture develops decay effect, a glue binder and glulam is produced , which is largely protected from rotting when moisture is attacked by diffusion of the substance into the surrounding wood, with boron compounds in particular being particularly environmentally friendly.
  • the boron and / or fluorine compound advantageously contains one or more of the substances boric acid, borates, soluble fluorides, silicon fluorides, fluoroborates.
  • this advantageously contains a pigment or dye.
  • a groove expediently runs in the middle of the longitudinal axis of the lamella, but it can also run asymmetrically, or there can be several grooves spaced apart in parallel.
  • the putrefactive, water-soluble and diffusible substance is expediently used in the form of a paste which is applied shortly before or at the same time as the gluing.
  • the paste solidifies in the wood after a short time and can also be processed at a higher temperature, so that it solidifies when it cools down.
  • the pastes are produced in a vacuum kneader.
  • compositions of putrefactive, water-soluble, diffusible substances have been found to be suitable:
  • three lamellae 1 are glued to one another, the two upper lamellae 1 in each case on a side 11 pointing downward in FIG have a central groove 2 which is filled with the putrefactive, water-soluble and diffusible substance.
  • FIG. 2 shows this structure with three lamellae 1, a substance being produced according to example 6 and filled into the lamellae 1.
  • a field test showed that with a wood moisture content of 80%, the substance had already been distributed after two months in such a way that it had reached the boundary line marked with G.
