Definitions
- Wood-based panels especially OSB panels
- the invention relates to a wood-based board, in particular OSB board, with wood chips glued under pressure and heat.
- OSB stands for Oriented Strand Board.
- Such wood-based panels with aligned strands or narrow-long wood chips are known, which can be oriented longitudinally and transversely in layers.
- the top layers regularly have length-oriented narrow-long wood chips, while the middle layer is made up of non-oriented wood chips.
- the classic glue formation of the wood chips takes place with phenolic resin, also by means of melamine-urea resin gluing or with isocyanite and polyurethane foam.
- the thickness of such wood-based panels is usually only up to 30 mm.
- OSB panels do not have sufficient flexural strength and transverse tensile strength to be able to be used as self-supporting wall elements in construction. Rather, the structurally stressed wall elements are regularly formed by two such wood-based panels, which are connected to each other by squared timbers or beams. This results in a relatively complex construction. - The invention seeks to remedy this.
- the invention has for its object to provide a wood-based panel, in particular OSB panel, of the type described above, which can be used as a self-supporting wall panel.
- the invention relates to a wood-based panel, in particular OSB panel, with glued wood shavings, in particular aligned narrow-long wood shavings, in a sandwich construction with cover layers on both sides and one or more middle layers arranged between the cover layers, the two cover layers being formed as at least double layers with an outer layer and an inner layer each with wood chips oriented in different directions are.
- cover layers on both sides and one or more middle layers arranged between the cover layers, the two cover layers being formed as at least double layers with an outer layer and an inner layer each with wood chips oriented in different directions are.
- the invention in the two outer layers of narrow-long wood chips in the longitudinal direction of the board and consequently in the longitudinal direction and in the two inner layers of narrow-long wood chips in the transverse direction of the board and consequently in the transverse orientation.
- Species of wood with a specific weight of 400 kg / m 3 to 500 kg / m 3 are preferably used for the cover layers. These include, for example, aspen, pine, spruce, fir and larch. Glue formation takes place in the classic way with phenolic resins, di-isocyanate in the Middle layer and other types of glue such as melamine-urea resin, polyurethane foam or the like.
- the wood-based panels according to the invention and in particular OSB panels can be produced in a conventional manner, after which after the oriented spreading of the glued narrow-long wood chips by means of a spreading machine for applying pressure and heat, a steam press, an HF-heated press, or else a continuously working one Press can be used. The result is a wood-based panel and in particular OSB panel with a specific weight of 400 to 600 kg / m 3 , which is characterized by high strength properties, insulation values and sound insulation values and is a high-quality component.
- FIG. 1 shows an OSB board according to the invention in a perspective view
- Fig. 2 shows a section A from the subject of Fig. 1 and
- FIG. 3 shows a cross section X-X through the object according to FIG. 1.
- the figures show a wood-based panel, namely OSB board 1, with wood chips glued under pressure and heat, which are aligned narrow-long wood chips 3 or strands in the cover layers 2.
- a sandwich construction with cover layers 2 on both sides and one between the cover layers 2 is arranged Middle layer 4 realized, the two cover layers 2 being formed as at least double layers with an outer layer 2a and an inner layer 2b, each with wood chips 3 oriented in different directions.
- the middle layer 4 is made up of non-oriented wood chips or scatterable wood waste.
- the plate thickness D is 150 mm.
- the cover layers 2 have a specific weight of 400 kg / m 3 .
- the entire wood-based panel 1 has a specific weight of 600 kg / m 3 . It can be used as a self-supporting wall plate.
- a wood-based panel with a specific weight of 600 kg / m 3 can have higher cover layer densities than the average specific weight.
- Very light types of wood in particular produce higher surface layer densities because they can be compressed very easily when pressed. If one starts from spruce / fir, then the specific weight is rather at 500 kg / m 3 ; 400 kg / m 3 is at the lower limit.
