Definitions

  • Timber components which are established in the soil, are usually impregnated with a chemical wood preservative and in this way the service life is considerably extended.
  • This protective measure is supported in the earth by the permanently high wood moisture and above the soil by the low moisture content and rapid drying after rain events.
  • a particularly critical area is the transition zone (earth / air zone) in which all wood moisture occurs and is
  • wood-destroying mushrooms an area for optimal growth finds. Since the chemical protection treatment is limited only to the impregnable areas of the sapwood, wood-destroying fungi can migrate through dry cracks that extend through the protected area into the unprotected heartwood and cause massive internal or nuclear fouling there.
  • This transition zone in the area of the ground / air boundary is dynamic; it depends on the seasonal differences in the amount of precipitation, which essentially influence the water content in the soil and thus the moisture supply to the underground area of the timber component.
  • near-surface soil areas may cause premature capillary moisture removal from the wood into the dry soil, and the transition area shifts below the soil surface.
  • rainy periods the high soil moisture, supported by the moistening of the above-ground area, shifts the transition area over the soil surface. This dynamic is also reflected in the harmful images of the inner rot; they sometimes extend over more than one meter inside the component and can expand up to one meter below the ground / air limit - in dry locations.
  • the present invention is the prevention of wood moisture gradient in the transition region between the sub-surface and above-ground area of wood components, which are founded in the ground, or in the transition region above the water surface in wooden components, which are installed in water.
  • This object is achieved in that in the transition region a comprehensive wood cross-section barrier which prevents the capillary water transport in the wood and the diffusion in the wood.
  • a hydraulic decoupling of the air-contacted and the moisture-contaminated area is achieved in the timber member and prevents the formation of a wood moisture gradient in the transition zone.
  • a sheath which complements the barrier layer of the subterranean area with an oxygen- and / or water-impermeable material (sleeve), so that in dry periods no premature, capillary moisture removal and no diffusion of water from the wood into the near-surface, dry floor areas can take place.
  • This casing begins above the ground in the region of the barrier layer according to the invention and encloses the underground area of the timber component completely or only in parts.
  • the soil-contacting side of the brain remains open in any case, so that the soil moisture here has unhindered access and the desired high wood moisture is ensured in the subterranean component area.
  • a gastight version of the sleeve material also prevents the ingress of oxygen into the damp wood.
  • the oxygen supply is minimized in the wet component area and the activity of the ubiquitous microorganisms then leads relatively quickly to anaerobic conditions.
  • Such anaerobic conditions additionally protect the wood, since under these conditions wood-destroying Basidiomycetes can not grow at all and mildew rotors can only grow to a limited extent or greatly delayed.
  • the cuff technology itself is well known and is used with noticeable success in many variants to support the chemical wood preservation measures in the area of the mast base and / or in the area of the earth / air zone.
  • EP 2 019 891 B1 describes a sleeve made of a metal foil which surrounds the underground base of the mast and is fixed on it via an overlying shrinking tube.
  • the effect of the metal foil is described as “oligodynamic” and thus utilizes the biocidal properties of metal ions released from the foil.
  • EP 2 574 435 A2 describes an almost identical sleeve system, only the effect of the metal foil is no longer described as “oligodynamic” but as "oxygen-consuming”.
  • a sleeve system which may consist of several layers, which are composed of different materials with different functions (Termitenschutz, reduction of drug losses in the soil, etc.).
  • All cuff systems are aimed either at a complementary chemical protective effect and / or at a physical reduction of the infestation pressure by wood-destroying organisms in the area of the earth / air zone.
  • Fig. 1 shows a wooden component (mast) with a central bore in the heartwood for
  • Fig. 2 shows a wooden component (support pile) with a circumferential, open towards the wood, self-sealing sleeve for the compression of the agent from the outside.
  • Fig. 3 shows a wood component (mast) with four holes which are perpendicular to the longitudinal axis by the distance V t from the center line of the timber member and the distance V h horizontally offset from each other to the core.
  • Fig. 4 shows a wood component (mast) with a bore which is offset at an angle W v to the longitudinal axis and by the distance V t from the center line of the wood component to the core was led.

  • V t offset from the center line of the wood component was guided into the core.
  • the inventive decoupling of the above and below ground water balance by a water and water vapor impermeable barrier layer prevents the occurrence of optimal growth conditions.
  • the use of the cuff technology according to the invention as supportive measure also lends itself to several reasons.
  • the water absorbed on the underground side of the brain is kept in the area below the barrier layer during seasonal drying periods and ensures permanently high levels of wood moisture.

Abstract

L'invention concerne un procédé de découplage physique de l'humidité en surface et souterraine d'éléments de construction en bois en contact avec la terre ou l'eau, un moyen de blocage destiné au découplage physique de l'humidité en surface et souterraine, ainsi qu'un dispositif de protection permanente contre une humidité accrue dans l'élément de construction en bois situé sous la couche de blocage. Selon procédé, au niveau de la zone terre/air ou de la zone eau/air il est prévu une zone de blocage, imperméable à la vapeur d'eau et/ou à l'eau, qui englobe toute la section transversale et sépare le bilan en eau de la partie de l'élément de construction en bois qui est en contact avec l'air de celui de la partie de l'élément de construction en bois qui est en contact avec l'humidité. Le dispositif est conçu pour réaliser une protection durable contre une humidité accrue dans l'élément de construction en bois situé sous la couche de blocage de manière à ce qu'une surface d'élément de construction souterraine soit entourée d'une couche imperméable aux gaz et à l'eau. Cette couche commence au niveau de la couche de blocage et se termine juste avant le côté inférieur de la région d'élément de construction souterraine.
