Definitions

  • the invention relates to a prefabricated plywood element according to the preamble of claim 1.
  • a prefabricated plywood element which consists of several layers of wood which are connected to one another by dowels.
  • the advantage of such a laminated wood element is that it can be used to produce walls which are made exclusively from a biologically produced material without any chemical binders, nails or the like. These walls are characterized by favorable static properties and good thermal insulation.
  • such laminated wood elements have a very high fire resistance and excellent shielding from high-frequency electrical fields.
  • a wooden wall is known from DE 297 21 848 U, which is composed of several layers of boards, but which are connected to one another by nailing. In order to reduce the manufacturing costs, the boards are rough-cut inside.
  • the object of the present invention is to provide a wall element which is made entirely of biological material and which enables a further improvement in the thermal insulation.
  • the structure according to the invention can be used to achieve an additional improvement in the thermal insulation properties without impairing the strength. Air chambers are created in the interior of the plywood element, which increase the thermal resistance, ie reduce the thermal conductivity.
  • An additional advantage of the design according to the invention is that the dowels are relatively high Contact forces between the individual layers can be generated and maintained permanently, so that the strength of the laminated wood element is not impaired by the smaller contact surfaces between the individual woods, which is caused by the profiling.
  • the additional processing of the individual woods by planing can also have the advantage that the maximum positive tolerance in the thickness range can be precisely limited.
  • wood that has not been reworked after sawing it can happen that several pieces of wood with positive tolerance deviations lie on top of each other at individual points on the wall element, which results in an inadmissible overall thickness locally.
  • This improvement is not only essential for saving energy, but also improves the fire protection properties.
  • a fire resistance class of F150 to F180 can be achieved with known plywood elements.
  • the profiling is designed as an arrangement of adjacent grooves that extend in the longitudinal direction.
  • the grooves are created, for example, by planing the individual woods with correspondingly profiled planing knives.
  • the profiling can also be produced by transverse milling, which, however, is generally more complex.
  • the end faces of the laminated wood element are designed to be closed. This is achieved when the edge area of the laminated wood element is free of grooves, which means that the grooves do not go through to the edge, but run out in front of the edge.
  • a particularly good thermal insulation can be achieved by providing at least two adjacent layers of wood, the mutually adjacent surfaces have grooves which are arranged at an angle to each other. In this way, a grid-like system of cavities is created, with the individual timbers resting only on the crossing points of the webs between the grooves.
  • it is particularly favorable if webs are provided between the grooves, the width of which is smaller than that of the grooves, the width of the webs preferably being between 20% and 80% of the width of the grooves. In this way, the contact areas between the woods are minimized.
  • Cable ducts or lines can be taken into account in the construction of the wall element in a preferred manner if at least one layer has a groove-like recess, the recess preferably being formed by milling or cutting out adjacent woods. In this way, the installation work after completion of a building can be simplified.
  • a particularly favorable connection can be achieved in that the bond between the dowels and the timber is essentially established by the force closure due to volume increase through moisture balance between the timber of the layers and the dowels.
  • the laminated wood element is made of one material and consists only of wood. In this way, disruptive influences from other materials can be excluded.
  • the laminated wood element has at least two layers perpendicular to one another and at least one layer arranged at an acute angle to them.
  • the vertical layers in the installed state absorb the majority of the static loads that act on the wall element.
  • the horizontal timbers are mainly used to connect the vertical timbers, and at least one inclined position serves to avoid possible parallelogram-like deformation within the wall plane.
  • Fig. 1 shows a part of a wall element according to the invention
  • the layer element 1 of FIG. 1 consists of six layers 2a, 2b, 2c, 2d, 2e and 2f of woods 3a, 3b, 3c, 3d, 3e and 3f.
  • the layers 2a, 2c and 2e are arranged so that the longitudinal axis of the woods 3a, 3c and 3e are horizontal, while the layers 2b and 2f are arranged vertically.
  • the layer 2d has diagonally oriented woods 3d.
  • the individual layers 2a, 2b, 2d, 2e and 2f are held together by dowels 4, as is described in WO 00/03850 A.
  • the woods 3b, 3c, 3d, 3e and 3f are profiled by grooves 5 which run in the longitudinal direction, the woods 3a and 3f being smooth on the surface facing outwards.
  • Recesses 6 are provided between individual pieces of wood 3b of the layer 2b, which are used to hold cables or lines.
  • the grooves 5 in the embodiment of FIG. 2 are essentially trapezoidal in shape and have a depth t of 3 mm and a width c of 3 mm.
  • the width b of the webs 7 between the grooves 5 is 2 mm.
  • the depth t can vary between 0.5 and 8 mm or more, the widths b and c can be up to 40 mm, in special cases up to 100 mm.
  • FIG. 3 essentially corresponds to that of FIG. 2, but the grooves 5 are designed in a wave shape.
  • the present invention makes it possible to significantly increase the thermal resistance of a wall element with practically the same strength.

Abstract

L'invention concerne un élément de bois stratifié préfabriqué comprenant au moins trois couches liées entre elles (2a, 2b, 2c, 2d, 2e, 2f) d'éléments en bois du type poteau ou planche directement adjacents (3a, 3b, 3c, 3d, 3e, 3f), dont la jonction s'effectue au moyen de chevilles (4) qui traversent les couches (2a, 2b, 2c, 2d, 2e, 2f) d'éléments en bois (3a, 3b, 3c, 3d, 3e, 3f), les éléments en bois (3a, 3b, 3c, 3d, 3e, 3f) d'au moins deux couches voisines (2a, 2b, 2c, 2d, 2e, 2f) s'étendant dans des directions différentes. Une isolation thermique améliorée est obtenue grâce au fait que les éléments en bois (3a, 3b, 3c, 3d, 3e, 3f) sont au moins partiellement profilés sur les surfaces se trouvant à l'intérieur de l'élément en bois stratifié.
