Definitions

  • the invention relates to a lightweight board according to the preamble of claim 1, to the use of lightweight panels for creating a house body according to the preamble of claim 10 and to a method for producing a lightweight board according to the preamble of claim 11.
  • the present invention is in the field of new lightweight building boards based on wood, which are formed with a plurality of flatly bonded layers, which are aligned with flocks of laterally juxtaposed with each other in a same layer, but in different layers with different angles to each other , bounded on their side edges and provided with a plurality of grooves boards are formed and which for furniture, but especially for the establishment of simple and inexpensive, especially further sound and / or noise insulation, in a simple way with low tool and personnel costs quickly Buildable buildings of various kinds, such as houses, cottages, stables, exhibition halls and the like. Can be used.
  • WO 2011/060468 A1 Wood construction elements with bonded layers are known, wherein the layers are constructed of boards, which each have a grooving on surfaces facing each other. The grooves and at WO 2011/060468 A1 Also, the boards of two directly adjacent layers are aligned transversely and diagonally to each other. It has now been shown that large internal stresses can build up in the finished timber components, which cause deviations from the desired planar shape in the timber construction elements. In addition, these wood components are insufficiently elastic and also have no high flexural strength so that with one-sided clamping the load capacity until breaking is only small.
  • the object of the invention is now to find a simple solution with which tension-free as possible lightweight panels with sufficiently high elasticity and high residual strength can be provided with strong deflection.
  • the lightweight panels in buildings to earthquake vulnerable places should be used.
  • the object is achieved by a lightweight board with the features of claim 1, or the use of this lightweight board for creating a house body according to claim 10 and by a method for producing a lightweight board according to claim 11.
  • the dependent claims describe alternative or advantageous embodiments, which solve further tasks.

This ensures that no long webs in the fiber direction of the boards can be formed on the outsides of these layers. Of the short repeatedly interrupted web areas do not stress, even in large moisture differences in the lightweight panel.
  • the adhesive joints are narrow areas in which abut the short webs of the two connected layers projecting between the grooves .
  • There is no large area glue layer which could undesirably restrict moisture permeability perpendicular to the large outer surface of the lightweight board.
  • the boards of at least one layer are laterally bonded to one another by tongue and groove on their side flanks.
  • These connections between the adjoining boards of a layer ensure that the layer does not break along the connections between the boards at a high bending load, but that the introduced bending energy is absorbed by the above-described deformations in the webs.
  • the different orientation of the boards of different layers also contributes to the strength.
  • the tongue-and-groove connections between the boards of a layer have the additional advantage that the layers can be loaded more quickly after the side flanks of the boards have been glued and the boards of the layer run flush along a plane.
  • the present invention is a multi-layered, in its basic form - preferably elongated - rectangular lightweight board based on wood with flat bonded together layers of flocks of mutually parallel, grooves having laterally bonded boards.

Cork exists, are bound together.
  • lightweight construction panels are particularly preferred according to claim 2, whose layers are formed with skewed arranged boards, each having a family of grooves, but specifically targeted in the direction of Wood fiber, ie parallel to the side edges of the boards are aligned and which are each crossed by a family of other parallel grooves.
  • a building board basically as described above is carried out so that on the at least one layer of the central layer mentioned in claim 1 on both sides in each case at least one further layer is bound surface, - the further layers, the laterally bound, elongated boards at a second acute angle (- ⁇ , + ⁇ ) are aligned to the longitudinal side edges of the lightweight board and the second acute angle (- ⁇ ) of the boards bound to the adjacent layer of the middle layer Layer has a size negative to the size of the first angle ( ⁇ ) of the boards of this layer and has a different or equal angular amount.
  • the new lightweight panel comprises a central layer with three layers.
  • the bond between the layers is preferably achieved with adhesive bonds between the adjoining faces of the paralellogrammflambaigen islands. With the above-mentioned relationships between the areas claimed by the grooves and the sum of the areas of the islands, it is ensured that the adjoining faces are sufficiently large for the required bond. Because the adhesive bonds are limited to the adjoining faces, a good moisture exchange can be ensured by the lightweight board. Nowhere is there a coherent adhesive layer acting as a moisture barrier.
  • the lightweight panels according to the invention in which a family of grooves on each major surfaces of each of the laterally bonded boards of individual or all layers of the lightweight board is formed with mutually parallel grooves, which is a substantially consistent with the course of the wood fibers of the boards longitudinal extent have, and which "fiber conforming" arranged grooves are crossed by the grooves of each other Nutenschar at an angle.

  • milled edge areas or chamfers run as small channels diagonally downwards and can thus deduce the rainwater striking the respective board controlled to the side, which a different wetting and thus a different growth or a different discoloration of the upper and lower portions of a wall prevented.
  • a substantial further object of the present invention is a plate-like lightweight construction element, in particular a lightweight wall or ceiling element and in particular a house body formed with a plurality of these elements, which is characterized in that it or with a A plurality of - as described above - on their side edges by means of connection grooves and springs positively bonded together lightweight panels is formed, said Anaptitati means of at least one, but preferably more, for example arranged spaced apart, and optionally intersecting, forming the body of the building lightweight components of side walls, partitions, bottom wall and / or ceiling or roof surfaces connecting and exciting, adjustable in their clamping force to a few, preferably up to 8, centimeters stretchable strap or Tensioning bands is accomplished.
  • clamping elements themselves are concerned, it is provided in one embodiment that they are formed with a strong spring interconnecting the two band ends which, in particular in the event of fluctuations, e.g. As a result of earthquake events, cause the house body is not damaged, since a certain flexibility and mutual displacement of the wall elements is given due to the targeted limited elasticity of the straps.
  • a very significant advantage of the present invention is that all tools necessary for the preparation of the boards and thus the components, such as machines and the work steps to be performed are so simple that they can be performed by just trained workers and the mechanical effort on a Minimum is reduced.
  • the manufacture can be carried out directly on site, e.g. in each case in a disaster or earthquake area, without much effort with only briefly trained forces without the need of skilled workers to be carried out, which is particularly beneficial for use in countries with low resources and in particular with increased or high risk of natural events.
