Definitions

• the invention relates to a bandage for the care of built-in earth masts, comprising a carrier film, means for securing the applied to the mast bandage and acting on the mast active ingredient.
• the active ingredients acting on the mast such as insecticides, fungicides, algicides, bactericides, etc.
• the pad at the base of the mast fixing this pad consists of a self-adhesive film and has an additional sealing film substantially for the protruding from the ground part of the bandage.
• a bitumen seal is applied to prevent the ingress of water from above.
• a simpler known form of such a bandage is the "Postsaver" system, in which a simple PE film carries an adhesive layer of bitumen. This sealed the surface of the already impregnated wooden mast in the earth-air area.
• it can not be fully considered to be a wood preservative because its protective effect is due to the sealing of the wood surface by the bitumen forming the fixer.
• attaching in the form of caps is described. However, this essentially restricts this use to factory equipment of poles or piles and precludes the subsequent care in situ if one does not want to fully excavate the object to be treated.
• a mast protection system called Permadur® has been proposed recently, in which a thin, about 0.1 - 0.3 mm thick metal foil is fixed by means of a 1.5 - 3 mm thick tube made of shrink film at the mast base ,
• the metal foil is copper and its alloys, in particular brass, which develop biocidal activity by slow release of metal ions diffusing into the wood, while in the special case of brass its zinc content occurs as an additional active substance and the adaptation of wood-destroying fungi prevented.
• the shrink film is further protected by an overlying PE film, which is about twice as wide as the metal foil.
• both the metal foil and the shrink film tube can be attached only at the factory and the metal foil itself is very expensive and expensive. Especially when masts or piles so protected are placed in the area of curious grazing livestock, the life is limited, and it goes without saying that care in situ can not be done, but the old mast are replaced by a factory-equipped new got to.
• the invention is based on the object, in masts or piles of wood or similar material in particular the regular maintenance, so the fattening and pile care, to improve and to provide a bandage available for this purpose, compared to the known systems described a reduced , manageable cost of materials required and allows easy application to the free only in the earth-air area Mastfuß.
• the first means for fixing at least partially applied to the carrier film, and that the active ingredient or a mixture of active ingredients are at least partially applied to the means for fixing.
• the construction of this bandage is particularly simple and effective, since the first means for fastening, for example adhesive, are used in regions for fixing the active ingredient or the combination of active ingredients. Adhesive is as further explained below - a preferred first means for fixing in the invention.
• the active ingredients can be arranged on a central strip, ie in the middle region of the bandage, based on the height of the carrier film, while the outer regions of the carrier film serve exclusively for fixing the bandage to the mast.
• a bandage it is possible to ensure an absolutely firm fixation in the critical marginal areas and also in each case the appropriate special purpose of the mast or pile-shaped object and the circumstances of the environment appropriate drug agent in sufficient dosage to install where they are required to To protect the wood against any external influences, especially pests of whatever kind.
• Bandages with the active ingredients applied according to the invention are advantageously 100 mm to 600 mm, preferably 200 mm to 500 mm wide. In this way, they are easily handled by a person and cover at the same time with one or more windings around the mast to be obtained from a sufficient protection of the mast circumferential surface.
• a likewise advantageous embodiment of the bandage according to the invention is provided instead of directly with adhesive or in addition to the above-described adhesive with at least two bands carrying adhesive and optionally active ingredient, and which are arranged independently.
• These bands which are preferably mounted parallel to the bandage, the bandage can be securely fixed to the mast.
• the active ingredients are predominantly solids.
• Powdered active substances are preferably used.
• the active ingredients may advantageously be metal dusts. Particularly suitable are metal dusts containing copper and / or zinc.
• compounds containing copper and / or zinc may be used, for example, alloys, salts or organometallic compounds. It is also possible to use mixtures of the abovementioned substances. As a result, their positive properties regarding the protection of wood can be used especially against fungi.
• Powdery active ingredients advantageously have a diameter of 0.1 mm to 3 mm, preferably from 0.2 mm to 1 mm. This diameter helps to ensure the long-term release of active ingredients.
• the active ingredients as granules or gel bodies, which store the active ingredient or the mixture of active ingredients in order to release them over a long period of time, there is the advantage that an economical, slow release of the active ingredients over a long period of time is possible and when handling and processing the bandage no handling with liquids is required that could pollute the groundwater.
• the active ingredients are mixed with other additives, in particular with those additives which ensure the uniform delivery of active substance to the mast over long periods of time.
• Solid substances which are used as additives are preferably used. Typical solids which are suitable here are inert powders or fibers into which the active substances are introduced before being applied to the fastening means.
• a preferred design of the bandage as unrollable endless belt means that only one product needs to be processed and thus less errors arise when mounting the bandage.
• the means for fastening are preferably provided as an adhesive layer, which can be applied in a continuous process continuously and thus manufacturing technology cost.
• the adhesive layer may contain as an essential ingredient bitumen or butyl rubber.
• an adhesive layer, even the portion of an adhesive layer may be covered with a removable release agent, such as a release liner.
• the release agent, for. B. siliconized paper can then be withdrawn immediately prior to use of the bandage.
• the outer surface of the bandage can be configured as a release agent, for. B. be siliconized. For both embodiments, it is ensured that the bandage can roll off well and stick on.
• the carrier film may be fiber-reinforced, preferably formed with a fabric scaffold.
• the film may be elastic.
• the elasticity can be provided in one or in two directions and, if necessary, a rapid adaptation to form can be achieved by heating. It is convenient for the processing of the bandage when it is elastic in the circumferential direction of the mast to be bandaged, for example, to be adapted to a tapered mast.
• the bandage in the case of strongly conical masts, can advantageously be additionally fixed and, if necessary, sealed after being attached to the mast, by e.g. at the upper edge of the bandage, a second means for securing, e.g. an adhesive or sealant such as bitumen, a Velcro strip or an adhesive strip, but possibly also a shrink film or welding film is used.
• a second means for securing e.g. an adhesive or sealant such as bitumen, a Velcro strip or an adhesive strip, but possibly also a shrink film or welding film.
• mechanical means for fastening in particular brackets or nails can be used as a second means for fastening.
• a release agent is applied for the simplified handling of the bandage after the application of the first means for fixing and of the active ingredients.
• the release agent for example, siliconized paper, allows an uncomplicated winding and unwinding of the bandage.
• bandage a cost-effective and easy-to-handle item for the care of poles, pile work and the like in the boundary region between soil and air.
• Typical uses of the bandage are the use for the protection of round or squared lumber, poles, fruit or vine piles, palisades, hop rods or lumber used in the soil.
• This object can be used straight in the earth-air area, in the desired manner and according to the requirements of different applications such as termites contaminated soils, heavily soiled with fungus soils, already contaminated soils and the like.
• the cost-benefit effect is increased by the simple processing of a single carrier film, which needs to be available due to their easy windability only in relatively narrow, about 30-40 cm making up widths.
• a 35 cm wide, fiber-reinforced polyethylene film is fully coated on one side with a layer of butyl rubber.
• a center-aligned strip of 25 cm width granules in a particle size of 0.5-1.5 mm of copper particles and zinc particles in the ratio 50:50 in an amount of 200 g / m 2 is applied.
• siliconized release paper is applied on the thus prepared bandage.
• the bandage is then either divided into about 1 m long individual bandages and wound up and packaged for later use. Alternatively, longer bandage sections are rolled up and packaged. The longer bandage sections are then measured as multiple benefits on site and processed as a single bandage.
• a fiber-reinforced plastic film of 45 cm width is applied on one side in a width of 35 cm bitumen.
• 70% of the bituminised surface is sprinkled with a mixture of one part of copper granules with a diameter of 1 mm and one part of fiber particles with a diameter of 2.5 mm with a quantity of 150 g / m 2 .
• the fiber particles are fungicidal-impregnated cellulose fibers. The particles adhere to themselves on the bitumen without further action. However, in order to ensure that the relatively light fiber particles adhere securely, the coated bandage is again unrolled with a roller under slight pressure. As a result, even light particles adhere securely to the adhesive surface.
• the thus coated bandage is covered by siliconized paper and divided individual bandages or left as described above as multiple uses and rolled up and ready to use packed.
• the bandage according to Section 2 is additionally wrapped with shrink film at the protruding ends during installation, heated and thereby sealed at the upper and lower end in the utility model Since the thermal action required for shrinking the bitumen would undesirably liquefy, here is the edge region of the bandage not provided with adhesive for the second fastener.
• the bandage according to the invention is rolled up when inserting the mast, the siliconized release paper is removed in sections in each case to the extent that the coated film can be safely and easily aligned and fixed by a person on the mast.
• the film can be pulled around the mast in a user-friendly and error-free manner, providing effective protection.
• the one-sided applied on the film first fastener for fixing the bandage is sufficient.
• other fasteners such as shrink film, staples, safeties in the manner of a hook and loop fasteners or other aids can be used in addition, for example. To prevent cattle bite or to counter other mechanical impairments.
• the construction of the bandage according to the invention makes it possible to fix the bandage first on the mast and align and then to place and apply more fasteners. As a result, the assembly and processing of the bandage according to the invention of only one person without effort and error-free possible.
