Definitions

  • the present invention concerns a wood floor element for the production of a wood or parquet floor.
  • the invention further concerns a wood or parquet floor which is made up of a plurality of wood floor elements.
  • Wood floor elements are generally known which are usually provided with a tongue and a groove in order to be fitted together to form a wood floor or a parquet floor.
  • tongue-and-groove connection either gluing is effected or the configuration of the tongue and the groove is already of a shape which affords a fixed connection by means of positively locking engagement.
  • floating laying is effected in that case so that the individual wood floor elements are only fixed to each other but are not fixed to the floor.
  • Conventional wood floor elements in accordance with EN 13489 are of a triple-layer structure.
  • Such a wood floor element accordingly comprises an upper layer of hard wood, a central layer of solid wood which is arranged therebeneath in relation to the laid condition and has therebeneath a lower layer comprising a wood veneer.
  • the fibre directions of respectively adjacent wood layers are in that case usually oriented in mutually transverse relationship.
  • an underlay of a thickness of about 2 — 5 mm is required. That underlay is usually laid under the wood or parquet floor.
  • Such an underlay can for example comprise cork and can be provided in rolls or panels.
  • the object of the present invention is to propose a floor element or a wood or parquet floor which has the best possible foot step impact sound damping effect at the lowest possible cost.
  • a wood floor element for the production of a wood or parquet floor, comprising an upper layer of hard wood with a surface for providing a walking surface of the wood or parquet floor, a central layer of solid wood, and a lower layer of an insulating material, in particular cork, wherein the lower layer of insulating material is fixed directly to the central layer.
  • insulating material is used to denote a material which has a substantially increased level of foot impact sound insulation in comparison with a known wood veneer layer as the lower layer.
  • a lower layer of insulating material is fixed directly to the central layer.
  • direct fixing to the central layer is used to mean that no further wood layer or the like is arranged between the lower layer of insulating material and the central Layer of solid wood.
  • directly arranging the lower layer of insulating material such as cork at the central layer includes the arrangement of an adhesive layer or the like between the lower layer of insulating material and the central layer insofar as same is at any event provided merely for fixing those two layers together.
  • the known lower layer of wood is replaced by the lower layer of insulating material.
  • the lower layer of wood was hitherto deemed to be necessary for the structure of a wood floor element.
  • hitherto insulating layers such as cork layers for step impact sound insulation have been used, if at all, in the form of an additional layer, more specifically either as a layer which had to be additionally laid beforehand or in the form of at least a fourth layer on the wood floor element under the known lower layer of wood. It was realised in accordance with the invention however that, when using a lower layer of insulating material such as cork, it is possible to dispense with a lower layer of wood.
  • Such a wood floor element also satisfies the requirement for using an odd number of layers.
  • the wood floor element is characterised in that there is no further layer and in particular there is not a third wood Layer.
  • the wood floor element is thus constructed in the form of a triple-layer element, with the top layer of hard wood, the central layer of soft wood and the lower layer of insulating material such as cork.
  • the wood floor element overall can be produced in that case in the form of a stable element.
  • the wood floor element is characterised in that the central layer is made up substantially of a plurality of pieces of wood, in particular elongate wood pieces such as finger strips which are arranged in mutuality parallel relationship and which are stacked in a longitudinal direction of the wood element.
  • the wood floor element is in the form of an elongate fiat element.
  • the element which is substantially rectangular in plan view is for example at least double and preferably 5 — 10 times as long in one orientation as in another one.
  • the central layer which is usually thicker than the upper layer and is also thicker than the lower layer is in that case formed from a plurality of generally approximately identical pieces of wood. That means that the central layer can be advantageously manufactured as there is no need for a continuous piece of wood.
  • the fibre direction of the upper layer is usually in the longitudinal direction and the fibre direction in the central layer is usually in transverse relationship with the longitudinal direction.
  • the pieces of wood which are often also referred to as finger pieces or finger strips are stacked in the longitudinal direction and loosely joined together by means of an adhesive strip or a cut- in thread or wire.
  • the stability of such a wood floor element is achieved in particular by virtue of the fact that that central layer is arranged between the upper layer and the lower layer and in particular is glued fast thereto.
  • the wood floor element of a further embodiment is provided with anti-scratch protection and/or a protective lacquer or a floor oil.
  • a protective lacquer can provide for sealing the wood floor element.
  • the upper layer which forms an essential part of the wood floor element comprises, a material from the group spruce, deal, pine, poplar and hevea.
  • the materials of the upper and lower layers can basically be the same. In that respect high-grade materials are used for the upper layer whereas materials of lower quality can be used for the central layer.
  • the material for the central layer may have defects or the like such as for example knotholes.
  • the lower layer preferably comprises cork, in particular pressed cork, rubber cork, rubber granular material or a wood soft fibre panel. That provides a lower layer which is stable but sufficiently flexible.
  • Pressed cork is produced by comminuting cork to form cork grain, mixing the cork grain with binding agent, pressing the material obtained to form blocks or cylinders and cutting panels or webs from the cylinders.
  • the density of pressed cork is at least 250 — 550 kg/m 3 , in particular 250 — 350 kg/m 3 .
  • rubber cork a rubber granular material is additionally also added.
  • rubber granular material is mixed with binding agent and then produced in substance like pressed cork.
  • wood fibre panels wood is comminuted, provided with binding agent and formed into panels, in particular by pressing, in which case the finished panels contain a proportion of air.
  • the wood floor element is of such a nature that the upper layer is of a thickness in the range of 2.5 — 4 mm, the central Layer is of a thickness in the range of 7 — 9 mm and/or the lower layer is of a thickness in the range of 2 — 4 mm. Accordingly the central layer forms the thickest strongest region of the wood floor element.
  • the wood floor element is provided at at least one edge with a groove and/or at at least one edge with a tongue for connection to at least one further wood floor element. That makes it possible to connect a plurality of wood floor elements to constitute a wood or parquet floor, in the manner of a tongue-and-groove connection. It is desirable for both the groove and the tongue to be provided on the central layer. That means that the lower layer of cork and also the upper layer can be in the form of a simple straightforward element without particular configurations at the edge, in particular they can be in the form of a rectangular element.
  • the upper layer, the central layer and the lower layer are firstly produced separately and then the three layers are glued fast together to form the wood floor panel.
  • a wood or parquet floor which is composed of a plurality of wood floor elements in accordance with one of the preceding claims. That makes it possible to provide in a simple and inexpensive fashion a wood or parquet floor which at the same time has an advantageous step impact sound insulating effect.
  • a wood or parquet floor can be laid without further underlays directly on a floor such as for example a concrete floor or a stone or hard plaster floor.
  • Figure 1 diagrammatically shows a portion of a wood floor element in accordance with the state of the art, which is to be laid together with an additional, floating cork underlay,
  • Figure 2 shows a portion of a four-layer wood floor element in accordance with the state of the art
  • Figure 3 shows a portion of a triple-layer wood floor element in accordance with the claimed invention.
  • a triple-Layer wood floor element is made up of an upper layer of hard wood A, a central layer of soft wood or lower-grade hard wood B and a Lower layer of wood veneer C. Those three layers are glued fast to each other.
  • an underlay Dl is additionally laid loose on a floor such as for example a concrete floor E, in order to compensate in particular for unevenness and irregularities in the floor E.
  • Such an underlay Dl can be composed of panels or provided from a roll, as shown in Figure 1.
  • a four-layer wood floor element as shown in Figure 2 is known from the state of the art for improved step impact sound insulation.
  • the upper layer A, the central layer B and the lower layer of wood veneer C correspond to the structure of the wood floor element of Figure 1.
  • a layer of cork D2 is provided as step impact sound insulation under the lower layer of wood veneer C.
  • Those four layers are glued firmly together and substantially form the four-layer wood floor element.
  • That wood floor element 1 comprises an upper layer 2 of high-grade hard wood, a central layer 4 of solid wood and a lower layer 6 of cork.
  • the upper layer 2 and the central layer 4 can correspond to the upper layer A and the central layer B respectively of Figure 1 or Figure 2.
  • the lower layer 6 is made from cork and can correspond to the additional layer D2 for step impact sound insulation as shown in Figure 2.
  • the upper layer 2, the central layer 4 and the lower layer 6 are glued firmly together and thus form the stable wood floor element 1.
  • the illustrated wood floor element 1 can be laid directly on a floor such as for example a concrete floor.
  • the illustrated wood floor element 1 has a groove 8 and a tongue 10 at the central layer 4 in each case.
  • the upper layer 2 of hard wood is composed of a plurality of elongate partial wood elements 12 which are fixedly glued together or can comprise a piece of wood of large area of dimensions in respect of width and length which are identical to the wood floor element 1.
