Definitions

  • the invention relates to a wooden panel with a number of wooden beams arranged side by side with parallel to each other extending longitudinal axes, of which at least two are above a tongue and groove connection are interconnected.
  • Such wooden panels are used, for example, for production of solid wood ceilings used in buildings.
  • the wood panels are usually layer glued Wooden beams used. Given yours to get the one you want The load-bearing capacity of the solid wood ceiling has the required thickness primarily used in prefabricated wooden panels considerable weight. This makes handling more conventional Wooden panels of the type specified at the beginning are made significantly more difficult.
  • it has been used with conventional wooden panels proven to be disadvantageous that the tongue and groove connections especially when the wooden beams swell or shrink exposed to great stress and therefore particularly must be stable.
  • the Invention based on the object, under warranty a high load-bearing capacity especially light wooden panel Provide initially specified type, which is a special simple execution of the tongue and groove connections between allowed the individual wooden beams.
  • a wooden panel according to the invention with this task is solved, is essentially characterized in that at least one of the wooden beams from a plurality of in Longitudinal direction of the bar and parallel to each other a recess passing through the beam in the axial direction enclosing components.
  • the weight can the wooden panel is reduced without impairing its load-bearing capacity be because at the center of weight loss Recess provided wooden beams only a very slight influence on the load-bearing capacity of those formed from these beams Has wooden panel. Therefore, wooden panels according to the invention can given load capacity with approximately the same thickness are like conventional wood panels, so that a total weight reduction through the central recess in the wooden beams is achieved.
  • the swelling and shrinking behavior the wooden beams are influenced so that any changes in shape mainly in the area of the central recess of the beams occur.
  • the stress on the tongue and groove connection by swelling and shrinking of the individual Wooden beams can be significantly reduced, which is ultimately a special one simple execution of the tongue and groove connection between allowed the individual wooden beams.
  • a wooden board with a particularly high strength can be realized when at least one of the wooden beams is on one of its outer surfaces preferably two in number Longitudinal direction of the bar running parallel to each other, respectively grooves separated from each other by a spring and on the a corresponding number on the opposite outer surface complementary to each other separated by a groove Has feathers.
  • Wooden plate have about the same shape.
  • the wooden beams in the Area of the tongue and groove connection glued together to to form such a viable unit. If the wooden beams such a wooden plate, for example, by Exposure to drying caused shrinkage, arise between individual wooden panels of a solid wooden ceiling wide joints that give the visual appearance of the solid wood ceiling affect. This deficiency can be remedied if at least two of the wooden beams are paralleled by at least one to the main surface of the wooden board and preferably perpendicular extending to the longitudinal axes of the beams, preferably connecting element formed in the form of a screw are connected.
  • connection of the individual wooden panels allowed to the cohesive connection of the wooden beams more conventional Wood panels the formation of joints between each Wooden beams of a wooden panel according to the invention.
  • connection of the individual wooden panels allowed to the cohesive connection of the wooden beams more conventional Wood panels the formation of joints between each Wooden beams of a wooden panel according to the invention.
  • the connecting elements preferably formed in the form of screws are expediently in a groove of one of the inserted wooden beams to be connected, penetrate this wooden beam and then penetrate into the neighboring one Wooden beams.
  • the use is comparatively shorter Allows screwing if the wooden beams with a preferred in the recess extending in the axial direction end bore, and the screws the wooden beam Only push through starting from the central recess.
  • the screws can be inserted into the hole with one Tools are screwed in.
  • connection means in the form of a screw for Joining adjacent wooden beams is used proven to be particularly useful from a manufacturing point of view if only one of the wooden beams one threaded Section of the screw picks up while in the other wooden beam a thread-free section of the screw is added is.
  • the grooves of wooden panels made of such wooden beams are the grooves and springs of the well-known wooden beams with one over their bevelled across the entire width. It means that the groove walls of the known wooden beams starting from the groove floor an obtuse angle with the groove bottom over its entire width include or the side surfaces of the springs starting from their end faces an obtuse angle with the end faces lock in.
  • Wooden panels influence the swelling and shrinking behavior so that no change in the external shape of the wooden beams occurs and swelling or shrinking only the shape affect the central recess. Therefore, to manufacture the wooden panels according to the invention used wooden beams in which at least one spring has at least one Side surface area running parallel to the main surface of the wooden panel has, which preferably over a blunt Angle including the chamfer area in a vertical to the main surface. On this way, a reliable positive connection between the spring and a groove are also ensured groove wall area running parallel to the main surface of the wooden panel having.
  • the tongues and grooves formed in this way are special preferably mirror-symmetrical with respect to a parallel to the main plane.
  • Tongues and grooves are made use of the knowledge that the change in shape of wooden elements tangential to the tree rings is approximately twice as large as radial to the tree rings. Therefore, when using crossbars, there are no significant changes Modification of the outer surfaces, what the use of grooves and Springs with parallel to the main surface of the wooden plate Side surfaces or groove wall areas allowed.
  • the parallel to the main surface of the wooden panel side surface area the chamfer area connecting the spring to the end face serves to facilitate the introduction of the spring into the Groove of the adjacent wooden beam.
  • the wood panel 10 shown in Fig. 1 has a thickness B from 120 mm and consists of three arranged side by side Cross bars 20, 40 and 60 with parallel to each other Longitudinal axes, each of which has a width A of approximately 206 mm. Taking into account the joints between the individual wooden beams is a wooden plate with a total width of about 625 mm.
  • the wooden beams 20, 40 and 60 of the wooden plate 10 shown in Fig. 1 point about the same shape. This form is used in the following of the cross beam 20 explained.
  • the crossbar 20 consists of four a central, itself Recess 30 extending in the axial direction of the beam enclosing wooden elements 22, 24, 26 and 28, each of which two roughly a right angle and each forming part of the outer surface of the beam Has boundary surfaces on which the annual rings 22a, 24a, 26a and 28a of the wooden elements run approximately vertically.
