Problems solved by technology

[0007] The aforementioned problems lead to the fact that for the commercial manufacture (in particular according to the teachings of patent document CA02296554C) of biocomposite-building material panels, a certain product can currently only be achieved by a high reject rate and / or by adding a higher amount of adhesive properties, such as solidity targets
However, both of these will increase manufacturing overhead and production costs

Embodiment Construction

[0058] figure 1 Shown is an OSRB-building material slab 1 (the upper surface structure of which is not shown) having a thickness ranging from at least 3 mm, preferably 8 mm up to 40 mm or even beyond this range.

[0059] The load-bearing OSRB construction material slab 1 has a minimum density of, for example, from 500 kg / m 3 to more than 900 kg / m 3 at a slab thickness of 15 mm. Non-load-bearing OSRB-building material slabs 1 generally have a lower density, but at least 400 kg / m3 or 500 kg / m3.

[0060] One example of a 100% reed stalk-building material slab can achieve a density in excess of 800 kg / m3. A particularly high robustness can thus be achieved. There is likewise a higher compatibility for allergy sufferers compared to building material slabs based on, for example, straw.

[0061] An embodiment of a reed-stalk-hybrid building material slab in the form of a floor panel based on straw with added reed straw is particularly suitable for use in wet areas (eg bathrooms) c...

Abstract

Sheet, board or panel, in particular an OSRB (1) - Oriented Structural Reed Board - comprising a layer of material (2) made up of pressed reeds having a multiplicity of stems which are split predominantly longitudinally, so that it is also the case that the insides of the stems, at least in part, are accessible to a binder, wherein the binder is able to hold together the reeds for forming a solid sheet, board or panel. It is thus possible to provide a biocomposite sheet, board or panel based on sustainable raw materials which has improved properties and strength and requires only a particularly low level of production outlay. A further aspect of the invention relates to a method for producing an OSRB (1).

Description

technical field [0001] The present invention relates to a flat board, a wooden board or a panel, especially an oriented structural reed board (Oriented Structural Reed Board, OSRB)-flat board, and a manufacturing method. Background technique [0002] During the past few years there has been an increasing effort to produce slabs, boards or panels as building materials from sustainable, renewable raw materials, preferably from agricultural waste such as straw. In this context, wood, roughly in the form of chips or chips, is considered a non-durable raw material due to the global decline in tree stocks. Depending on the achieved mechanical properties, slabs, boards or panels based on this sustainable, renewable raw material can be used in the construction industry as non-load-bearing or even load-bearing building material slabs or biocomposite-building materials flat. [0003] Patent document CA02296554C discloses a method for manufacturing Oriented Structural Strand Board (O...
