Definitions

  • An Oriented Strand Board in the sense of this invention consists of at least one layer which is constructed with flat wood shavings, so-called strands.
  • the above-described layer forms the lower and upper cover layer and between them is the middle layer (in a 3-layer design), which has no preferred orientation of the stands. This distribution is also called "random" in technical language.
  • the middle layer is the innermost layer of the plate.
  • a 3-layered plate thus consists of an upper and a lower cover layer and a middle layer, a 5 or more layered plate of an upper and lower cover layer, a central layer and layers between the upper and lower cover layer and the middle layer.
  • a preferred embodiment of the invention is a 3-layer plate, 5-layer or multi-layer plates (an odd number of layers being useful). Even numbers of layers are just as conceivable.
  • a wall element, inter alia, for side panels of car trailers or the prefabricated house construction of glued together fiberboard is in the DE 197 46 383 A1 described.
  • the fiberboards also have a multilayer structure, they are not suitable as load-bearing elements.
  • the invention is based on the technical problem of specifying a component made of OSB boards, which is suitable for large-scale use and can be used for the construction of buildings.
  • An OSB plate suitable for this purpose is described in "First Eurostrand-OSB produced” from Holzweb.net from 09.03.2001.
  • the present invention describes a component made of large-sized wood-based panels, with high mechanical properties such as the parameters for bending, tension and pressure, without raising the specific gravity of the plate over the usual level. Furthermore, technological features of an OSB board are described, from which one can derive these increased mechanical properties and possible uses of this OSB board.
  • the properties of the wood-based panels according to the invention are influenced by the beach geometry and the most uniform design of the strands of the cover layer, the ratio of thickness of the cover layers to the total thickness or the basis weight of the cover layer to the total basis weight of the plate and the average specific gravity of the plate (density).
  • the two outer layers should consist in the finished product of at least 30 percent by weight of the total scattered chip quantity, which in sum of upper and lower cover layer corresponds to a proportion of at least 60%.
  • the remaining 40% account for the middle layer in a 3-layer plate.
  • the specific weight of the board should not exceed 700 kg / m 3, a value of less than equal to 650 kg / m 3 is desirable. This information refers to dry plates.
  • the production of the strands is usually made of round wood, which is preferably present in debarked condition.
  • the log logs are fed to a flaker, which produces strands of the desired dimension in a single operation by means of rotating tools.
  • a multi-stage production of the beaches is just as conceivable as z. B. from a rotary veneer, which is crushed into strands in a further step.
  • Fines are strands that are significantly different from the dimensions of the strands described above. Primarily during the production of fines should be avoided such as. B. by a gentle debarking and by regular sharpening of the cutting tools of the flaker. After Strandher ein a separation of the fine material from the beach but also conceivable.
  • the proportion of fines can only be reduced to a still tolerable minimum proportion, but can not be prevented.
  • the proportion of fines can be quite 10 to 15 weight percent based on the weight of the finished plate.
  • the wood of the beach is not relevant. In principle, all types of wood such. As poplar, birch, beech, oak, spruce, pine and the like possible.
  • the pine has proven to be particularly suitable due to its good machining properties and due to its relatively high resin content.
  • paraffins or waxes may be added.
  • the application can take place in the form of a melt at the required elevated temperature (liquid wax application) or for emulsions at about room temperature.
  • urea-formaldehyde glues UF
  • melamine-formaldehyde glues MF
  • phenol-formaldehyde glues PF
  • binders based on isocyanate eg PMDI
  • binders based on acrylates have proven successful.
  • a mixture of at least two of these types of binder is used, but also mixtures of several types of glue is conceivable.
  • the term "mixture” is understood to mean not only a mixture of different types of ready-to-use binders, but also a mixture of various of the cited types, which already results in the course of production as a mixture. So z.
  • melamine-urea-formaldehyde glues (MUF) or melamine-urea-phenol-formaldehyde glues (MUPF) by co-cooking in the same reaction vessel (reactor) are produced.
  • the individual layers of the plate may also contain different types of binders and mixtures thereof, wherein it is advantageous for multi-layer plates for stability reasons, those layers, which are each arranged - in relation to the plate surfaces - in the same position, with the same binder type or to provide the same mixture.
  • PMDI isocyanate-based binder
  • the proportion of binder and the binder type are decisive for the desired mechanical and technological properties.
  • the content of binder depends on the type of binder. binder contents for UF, MF, PF and their mixtures are in the range between 10 and 15 wt.% Calculated (in mixtures as the sum of the components used) as a solid resin based on the dry mass wood strands. When using isocyanates, the binder content can be reduced to 5 to 10 wt.%.
  • the gluing of the beaches takes place before the beach mat is formed.
  • Beleimtrommeln are provided for this, which allow a continuous gluing in the run.
  • the drums rotate around their own longitudinal axis and thus keep the introduced beach material constantly in motion.
  • a fine glue mist is created by means of nozzles, which is reflected evenly on the beach.
  • the drums have built-in components, in order to be able to constantly pick up the beach material and to transport the beach material from the inlet into the drum to the outlet.
  • An oblique inclination of the drum in the longitudinal direction can assist the forward movement of the strands.
  • the achievement of the desired mechanical and technological properties is influenced by the targeted orientation of the strands.
  • The% set of chips, which may deviate more than +/- 15 ° from the selected direction of orientation is small. Nevertheless, in the "transverse" direction of the plate, there are still sufficient strengths and stiffnesses, since the scattering process always gives a deviation from the desired orientation.
  • the target orientation of the strands will depend on the position of the beach ply within the panel.
  • the two outermost layers, the cover layers, should be aligned parallel to the plate length as previously described for a single-layer plate.
  • the strands of the single center layer are oriented without a preferred direction (random).
  • a plate structure of more than 3 layers is also conceivable.
  • the number of layers will be odd
  • the beach orientation of the cover layers and the middle layer as described above and the orientation of the other layers may be arbitrary.
  • the preferred beach orientation of these other layers is crosswise to the beach orientation of each outer adjacent location.
  • a random orientation of individual layers is also possible.
  • the shaping of the beach mat from the various superimposed layers is accomplished by a spreader. For each layer is usually a scattering head available. Its task is to orient the glued strands in the desired direction or randomly arrange them. After spreading the mat, the pressing takes place to a stable plate-shaped product under the action of pressure and temperature. This can be done either in cycle presses (single or multi-day presses) or in continuous presses. The latter make it possible to produce an endless plate belt which can be cut into the desired formats.
  • the plates can be ground after production. This achieves a homogeneous plate thickness with small thickness tolerances and improved conditions for gluing two or more plates to components as described below. However, with sufficient board surface quality and sufficient thickness tolerance of the boards, gluing without prior sanding is also possible.
  • FIG. 1 shows a wooden material plate 1 as described above, which is composed of three beach layers.
  • the upper strand layer 2 shows a preferred orientation of the strands 5 in the longitudinal direction of the plate. It can be seen that the strands 5 of the cover layer 2 are not aligned strictly parallel to the plate length, but nevertheless given a high degree of orientation.
  • the middle layer 3 consists of strands 6, which are somewhat smaller in size than the strands of the cover layers 2 and 4. The orientation of the strands 6 of the middle layer 3 is random.
  • the lower cover layer 4 is constructed in mirror image to the upper cover layer 2.
  • FIG. 1 shown plate 1 are selected as reference only as an example of a section of a large-sized plate and do not match the real dimensions plate length and plate width.
  • FIG. 1 also shows that the thickness s1 of the two cover layers (both the lower cover layer 4 and the upper cover layer 2 constructed in mirror image) is each about 30% of the total thickness s of the plate and the thickness s2 of the middle layer 3 is about 40%.
  • individual plates 1 may have a thickness s to about 50 mm and formats of 2.8 x 15 m and can be used in a variety of construction.
  • the plate length of 15 m should not be understood as an upper limit. However, it has been shown that both for the production and subsequent plate manipulation in the course of further processing here is a reasonable order of magnitude at 10 to 15 m.
  • FIG. 2 schematically shows such a component 10 which is made of 3 individual plates 1.
  • the individual plates 1 with an adhesive such. B. isocyanate at least partially bonded over a large area.
  • This component can, for. B. be used in house construction for exterior and interior walls, with the advantages that elements corresponding to the wall length without joints over a full storey height (up to 2.8 m) can be produced.
  • the common house-building practice eg single-family house, multi-family house shows that wall elements with a length between 10 and 15 m are quite sufficient to be able to produce entire wall, ceiling and roof elements.
  • the 3-layer OSB board of the following example was manufactured on an industrial plant.
  • Stranded logs are made from decorticated pine logs with a length of approx. 150 mm, a width of between 10 and 25 mm and a thickness of between 0.5 and 0.8 mm. Fines are, as far as possible, already separated. Subsequent drying reduces the moisture content of the strands of both layers to between 3 and 5%. Before gluing, the proportion of fines is minimized by means of screening devices.
