Definitions

  • the invention relates to building structures, and more specifically, to layered building panels of wooden parts.
  • prefabricated wooden elements are widely used, made in the form of wall and / or ceiling elements mounted directly on the construction site.
  • Glued multilayer wood panels consisting of several layers of wood parts glued together, in particular plywood, joinery and (AU 80770/82 B, USSR copyright certificate N ° 1377352, European patent N ° 0194238). These panels are mainly used as finishing materials and for the manufacture of unloaded or lightly loaded parts of furniture products.
  • Multilayer wood panels with intersecting wood are known.
  • glued laminated wood panels comprising layers of wooden boards joined side ends and superimposed by the layers on top of each other, in which the directions of the wood fibers in adjacent layers are crossed, longitudinal grooves for glue are made in the layers.
  • adhesives form a diffusion barrier that impedes normal moisture exchange.
  • multilayer wood panels are known with crossed wood fibers in adjacent layers, in which the board layers are interconnected by non-wood pins (metal, aluminum, plastic, fiberglass reinforced elements), and their ends are joined to the tongue and groove tongue.
  • Multilayer wood panels with non-wooden dowels are characterized by their high cost and are difficult to dispose of.
  • a disadvantage of the known panel that impedes the achievement of the following technical result is that under the action of bending forces and forces oriented in the same direction with the pins, the lateral joints of the parts in the layers diverge and delaminate due to the tangential displacement of the layers relative to each other and plane-parallel sliding wooden parts along the pins.
  • board means lumber up to 100 mm thick and more than double the width.
  • face means any of two opposite wider longitudinal surfaces of the lumber, as well as any longitudinal surface of the lumber with a square cross section.
  • end face means the front or rear end of a wooden product.
  • lateral end or “edge” means any of the two ends of the wooden products forming the layer, located between the surfaces of the layer.
  • stud means a rod fastener that is installed with an interference fit for fastening layers of wooden parts.

  • the panel parts are interconnected with wooden dowels, pins and / or dowels (fasteners) with interference.
  • Preload is provided by increasing the volume of fasteners as a result of equalization of moisture between them and wooden parts.
  • Fasteners with reduced moisture content are used relative to the parts, for which the elements are usually dried to a greater extent than the parts, the dry elements are placed in the holes inside the parts, and the sizes of the cross-sections of the elements and holes are selected so that an extension arises when the elements expand.
  • the strength of the joint is affected by the initial moisture of the parts and fasteners, as well as the coefficients of their volume expansion upon absorption of moisture.
  • the location of the dowels at an angle to the main plane of the panel and the orientation of the dowels in several non-parallel directions, that is, the crossing of the dowels, eliminates the delamination of the panel under the action of forces directed at any angle to the normal of the panel.
  • the pins can be located at an angle of 45 degrees to the plane of the panel and can be oriented in two different directions so that the pins having the same orientation are located in mutually parallel planes, and between them also in mutually parallel planes there are pins in a different orientation , while the pins in adjacent planes are crossed at an angle of 90 degrees.

  • the panel comprises at least one layer of wooden parts with a cross-sectional height less than the thickness, joined together by narrow ends.
  • Such layers are most suitable for connecting power layers made of parts with a large cross-sectional area and for creating outer layers.

  • the panel comprises at least one layer of wooden parts with substantially the same height and width
  • Preferred parts with substantially the same height and width of the cross section are bars with a coefficient of uneven cross section from 0.7 to 1.3.
  • the wood fibers in said at least two layers of wooden parts with substantially the same height and width of the cross section are oriented in substantially the same direction. This makes it possible to form panels containing several power layers interconnected by layers with intersecting fibers.
  • At least one of said layers of parts with crossed wood fibers is arranged.
  • said wood parts of at least two adjacent layers are staggered. This arrangement of the layers is most preferable, since during bending, the panel does not diverge over the entire thickness, but only over the thickness of the individual layers, which makes it possible to increase its moisture and noise impermeability.
