Definitions

  • the invention relates to a plate-shaped wooden component made of at least three layers glued together, at least the middle layer of which forms a corrugated profile, on the back of which the subsequent layers are glued.
  • wood Due to its fiber structure, wood has different mechanical properties in different directions. In order to obtain plate-shaped wooden building elements with strength properties that are largely independent of the direction of loading, in spite of this anisotopy, various wood layers with intersecting fiber orientations are glued into plywood panels that have high strength and are versatile in use. Due to the comparatively low specific mass of the wood usually used for this purpose, multilayer glued wooden panels made from it have a low weight despite the achievable strength, so that the use of such panel-shaped wooden components for a variety of purposes is also recommended with regard to environmental compatibility and the circumstances that wood is a natural, renewable material. The use of plate-shaped Wooden construction elements could be strengthened and expanded to other areas of application if, on the one hand, the thermal insulation was improved and, on the other hand, the weight of the wood construction elements could be further reduced without having to accept corresponding losses in strength.
  • the bending strength of the corrugated profiles is significantly reduced due to the incised grooves, which is further compounded by the fact that the thickness of the corrugated profiles must be comparatively large due to the machining, which has a disadvantageous effect on the total weight of the wooden components.
  • the invention is therefore based on the object of designing a plate-shaped wooden component of the type described at the beginning with simple constructive means such that a high component strength can be combined with high thermal insulation at a comparatively low weight.
  • the invention solves this problem in that the corrugated profile consists of a wood layer formed by steaming and pressing and that the cavities resulting from the corrugated profile of the middle layer between the layers have a heat-insulating filling.
  • the higher flexural rigidity of the corrugated wood layer transverse to the corrugation can advantageously be exploited, taking advantage of the inherent strength that is not impaired by a machining profile, which increases the flexural strength of a wooden construction element made from it, the top layers of which act as tension and compression straps of the composite body obtained by gluing the individual layers.
  • the cavities resulting between the corrugated middle layer and the subsequent cover layers are provided with a heat-insulating filling, there is a plate-shaped component of comparatively low weight, which not only can meet high strength requirements, but also has advantageous thermal insulation properties that match the thermal insulation properties of a wood-based material noticeably outperform.
  • the thermal insulation filling can be constructed differently and can consist, for example, of a granular insulation material, ders advantageous constructional relationships when the heat-insulating filling is made up of natural fibers loosely blown into the cavities between the layers. Since the thermal insulation filling cannot be applied before the individual layers are glued together, because otherwise the gluing would be hindered by the filling, the thermal insulation filling must subsequently be introduced into the cavities, which can be achieved in a simple manner by blowing in loose natural fibers. The subdivision of the space between the top layers by the corrugated middle layer into separate cavities is a favorable prerequisite for a permanent, loose fiber cohesion of the blown-in fibers without having to fear a subsequent shifting or setting of the blown-in fibers. The thermal insulation properties of such a wooden building element are therefore preserved over its lifetime.
  • FIG. 1 shows a section of a panel-shaped wooden component according to the invention in a schematic cross section
  • Fig. 2 shows a further, differently constructed wooden component according to the invention in a spatial representation.
  • the plate-shaped wooden component 1 according to the exemplary embodiment according to FIG. 1 has a middle layer 2 made of a corrugated wood layer 3 which has been corrugated by steaming and pressing. In contrast to machining, this measure does not adversely affect the fiber structure of the wood layer 3, so that the advantages of such a fiber structure can also be exploited in the area of the wood layer 3 that has been turned.
  • layers 5 of wood panels are glued, so that through the layers 5 interconnected via the corrugated wood layer 5, a composite body is obtained which brings with it special strength properties, on the one hand on the corrugation of the wood layer 3 and on the other hand based on the inclusion of the top layers 5 as tension or compression belts.
  • the layers 2 and 5 consist of only one layer, these layers 2 and 5 can also be constructed in multiple layers in order to meet certain strength requirements in certain directions by special orientation of the fiber layer.
  • the cavities resulting between the corrugated wood layer 3 and the top layers 5 are provided with a heat-insulating filling 6, which consist of natural fibers, for example made of hemp or tow, which are loosely blown into the cavities. Due to the limited volume of the cavities, these fibers do not need any additional binding in order to secure the confusion achieved by the blowing. However, it is advisable to impregnate the fibers accordingly, on the one hand to achieve a fire-retardant effect and on the other hand to prevent decomposition by microorganisms.
  • two corrugated wood layers 3 are provided, which are each made from a peeled veneer wood.
  • the two corrugated layers of wood 3 are arranged so that their corrugations cross each other. Since an intermediate layer 7 is provided between the two corrugated wood layers 3, there are cavities between the corrugated wood layers 3 and the adjoining cover layers 5 or the intermediate layer 7, which are filled with a filling 6 made of natural fibers in order to ensure appropriate thermal insulation.
  • the plate-shaped wooden component 1 obtained in this way represents a composite body which, in terms of bending stiffness, can meet significantly higher requirements than a wooden component 1 according to FIG.
  • Wood layer 3 can be used with different bending behavior in different directions. Needless to say, the invention is not limited to the illustrated embodiments. The only thing that matters is the combination of at least one middle layer 2 of a corrugated wood layer 3 with top layers 5, the cavities formed being filled with a heat-insulating filling.
  • plate-shaped wooden structural elements 1 can be realized which can meet very different load requirements, with the filling 6 of the cavities made of a heat-insulating material making them otherwise external thermal insulation to be attached to plate-shaped components can be dispensed with.

Abstract

L'invention concerne un élément de construction en bois (1) sous forme de panneau, constitué d'au moins trois couches (2, 5) collées ensemble, dont au moins la couche centrale (2) forme un profilé à ondulations, les couches (5) adjacentes étant collées sur les sommets de ces ondulations. Pour que ce panneau non seulement puisse satisfaire aux exigences élevées en matière de résistance mais qu'il offre également un bon amortissement des bruits, il est proposé que le profilé à ondulations soit constitué d'une couche de bois (3) formée par exposition à la vapeur et pressage, et que les espaces vides formés par le profilé à ondulations de la couche centrale (2), entre les couches (2, 5, 7), comprennent une matière de remplissage (6) amortissant le bruit.
