Definitions

  • the invention relates to a parquet board according to the features in the preamble of claim 1.
  • Under two-layer parquet is understood to be a parquet, which as the first upper layer has a visible top layer of solid wood, also referred to as the wear layer, and as a second layer has a support plate. These two layers are interconnected.
  • the advantage of this type of parquet is that it is usually laid with a finished surface, for example varnished or oiled, and the on-site surface treatment is spared. Also from an ecological point of view, a two-layer parquet is advantageous because the raw material wood is spared. High quality, noble wood is used only for the top layer, whereas the support plate is made of cheaper, but possibly also more stable materials.
  • a parquet board in which the top layer consists of hardwood and with a support plate made of wood or Wood material is glued or glued.
  • the support plate should be provided on one or both sides with slots that can be arranged longitudinally or transversely, which should benefit an increase in thermal insulation.
  • the side edges of the parquet planks are provided with a profile that allows a glue-free connecting two parquet planks together in the plane of the parquet planks and perpendicular to this plane.
  • Two-layer parquet is often referred to as a glued parquet. Due to the two-layer structure, there is no stability for a floating installation. The laying takes place in the two-layer parquet by gluing, namely full-surface gluing. A full-surface bonding requires a ready-to-use surface. The substrate must be sufficiently level, compressive and tensile, free of cracks, clean and dry. The processing instructions of the adhesive manufacturer must be strictly adhered to. By means of a notched trowel, the adhesive is applied over the entire surface in accordance with the manufacturer's instructions, applying only as much adhesive as can be laid within the open time. The amount of adhesive depends on the absorbency of the subfloor. If the parquet planks are not fully glued and properly bonded, the parquet planks are warped and joints between the individual parquet planks can be created.
  • the invention is based on the prior art based on the object to provide an application technology improved parquet board, which allows a more stable bonding.
  • the carrier plate of a parquet board is provided at the bottom with slots, each slot having two depth sections.
  • the slot width in the slot-inside depth section is constant, preferably rectangular configured with parallel side walls, whereas the slot width increases in the mouth-side depth section towards the mouth, so it expands.
  • This funnel-like configuration leads to a significant improvement of the bond.
  • the adhesive penetrates better into the parquet board or the slots and interlocks with the parquet board. It comes to a highly stable and durable adhesive bond.
  • the slot geometry is used for adhesive absorption and ensures in particular a targeted bending softness or flexibility of the parquet planks in the longitudinal direction.
  • the ratio of the thickness of the support plate to the total depth of a slot between 1.2: 1 and 3: 1 dimensioned.
  • the ratio of the thickness of the carrier plate to the total depth of a slot is 1.4: 1.
  • the depth of a slot is 4 mm to 5 mm.
  • the width of a slot at the mouth is preferably at least twice as large as the width of the slot in the slot inside the depth section. With a width of the slot in the slot inner depth section of 2 mm, the width of the slot at the mouth of 4 mm, preferably 5 mm, large.
  • the spacing of the slots in the longitudinal direction of the carrier plate is chosen to be smaller in a parquet board according to the invention.
  • the distance was previously at 40 mm to 60 mm, it is in a parquet board according to the invention between 25 mm and 45 mm, preferably 30 mm.
  • the depth of the slots, their geometry and the spacing of the slots to each other ensure the desired bending softness of the parquet plank.
  • the adhesive parquet or the parquet planks should be as flexible as possible in order to be able to follow any unevenness of the substrate. This can be avoided voids that could otherwise be avoided only by very large adhesive orders.
  • the distance of the last slot to the head side is at least 45 mm.
  • the mouth-side depth portion of a slot has in cross section a trapezoidal configuration with oblique side walls, each side wall to the bottom at an angle of preferably 60 °.
  • the coupling of the parquet boards to one another can be improved in a known manner by providing locking means on the longitudinal sides and on the head sides of the support plate, which locking devices engage with each other in a floor covering adjacent parquet plank.
  • the slots also extend over the locking means, such as locking tongues or tabs.
  • the carrier plate may be a compressed fiberboard, in particular a high-density fiberboard (HDF).
  • HDF carrier plate is very rigid or stiff in terms of material and structure. Therefore, the particular shape of the slots according to the invention was chosen.
  • the inherently very rigid HDF carrier plate is given a bending softness. This allows the use of the HDF carrier plate with adhesive parquet.
  • the carrier plate forms the core of the parquet board. It is characterized by its high density, resilience and stability.
  • the slots provided in the carrier plate are provided over the entire width of the carrier plate. Due to the slots, the carrier plate is more flexible. tensions are avoided.
  • the slits help to ensure that the laid parquet floor boards do not warp.
  • the spacing of the slots with each other and the slot geometry ensures the desired flexibility or flexural softness of the parquet planks.
  • the highly stable, durable bonding which also allows mechanical surface treatment without problems, is achieved by contouring the slots according to the invention.
  • a counter-pull can be provided, in particular a counter-pull of paper.
  • This paper return accomplishes an additional stabilization of the parquet board transversely to the longitudinal direction.
  • a parquet board according to the invention may compared to the usual dimensions of parquet planks - often 45 mm x 600 mm - have larger dimensions, for example, a width of 100 mm or 140 mm with a length of 1,100 mm.
  • the use of parquet flooring with such large dimensions reduces the laying work and time.
  • the flexibility of the parquet boards in the longitudinal direction allows for the large dimensions, without increasing the requirements on the subfloor or its flatness.
  • the slots are sawn after the application of the counter-pull in the bottom of the carrier plate.
  • the slots can be sawn in the parquet flooring during the slicing process of the large format boards. But it is also possible to bring the slots only in the profiling process in the parquet planks, in which the long sides and the head sides get their profile.
  • a parquet plank can be delivered untreated, ie raw, on the upper side.
  • the processor then applies a top finish himself, for example, a natural oil or a varnish.
  • a Parquet floor according to the invention already at the factory with a coating, in particular a paint, preferably a topcoat, be provided.
  • the coating can be transparent and / or contain effect particles.
  • the coating may have impregnating properties.
  • the cover layer may be provided with a seal, for example an oil or a wax.
  • FIG. 1 1 schematically shows a schematically illustrated parquet plank 1 on one longitudinal side 2 and on one end face 3 a spring 4, 5 and on the other longitudinal side 6 on the other end face 7 adapted to the cross section of the springs 4, 5 groove 8, 9.
  • locking means 10 (see FIG. 4 ) are formed, which in engaging in a floor covering parquet planks 1 engage each other in latching engagement.
  • the locking means 10 comprise, as shown in FIG. 4 becomes clear, the grooves 8, 9 upstream limited resilient locking tongues 11, which can be joined with locking grooves 12 below the springs 4, 5.
  • About the springs 4, 5 and grooves 8, 9 parquet boards 1 both over their long sides 2, 6 as well as on their front sides 3, 7 gap-free and glueless tensile and pressure resistant be added.
  • the parquet board 1 is composed of a cover layer 13 of hard or solid wood and a support plate 14 of a high-density fiberboard (HDF) together.
  • the cover layer 13 and the support plate 14 are glued together.
  • the cover layer 13 is preferably made of a one-piece layer of hardwood and has a thickness d D between 2.5 mm and 8 mm. A two- or multi-bar design of the cover layer 13 is possible.
  • the support plate 14 is provided with slots 15.
  • the slots 15 extend from the bottom 16 and extend over a total depth t, which corresponds to half the thickness d T of the support plate 14.
  • the slots 15 extend at right angles to the longitudinal axis LA of the support plate 14 over its entire width b T and are arranged in the longitudinal direction of the support plate 14 at a distance a between 25 mm and 45 mm from each other.
  • the distance a between the slots 15 is 30 mm.
  • the distance a e of each last slot 15 at the head ends is greater than the distance a, and preferably by 50%. At a distance a of 30 mm, the distance a e of the last slot 15 at the head sides 7 is 45 mm.
  • each slot 15 has two depth sections 17, 18.
  • the slot-inside depth section 17 is configured rectangular and has a constant slot width b1.
  • the side walls 19, 20 of the depth portion 17 are parallel to each other.
  • the mouth-side depth section 18 has obliquely extending side walls 21, 22, which widen conically or funnel-shaped toward the mouth 23, so that the slot width b 2 in the mouth-side depth section 18 increases towards the mouth 23.
  • the side walls 21, 22 are slanted to the bottom 16 at an angle ⁇ of 60 °.
  • the width b2 of a slot 15 at the mouth 23 is twice as large as the width b1 of the slot 15 in the slot-inside depth section 17. In practice, it is planned that the width b1 is 2 mm and the slot 15 at the mouth 23 has a width b2 of 4 mm.
  • the contour of the slots 15 with the two depth sections 17, 18, wherein the depth section 18 widens funnel-shaped, causes the adhesive when installing the parquet board 1 penetrates deeply into the slots 15 and clawed to the parquet 1.
  • the contoured geometry of the slots 15, their depth t and the distance a of the slots 15 to each other ensure a high flexibility or flexural softness of the parquet planks 1 in the longitudinal direction.
  • the parquet planks 1 nestle or level themselves so suitable for installation to the ground.
  • the bottom 16 of the support plate 14 may be provided with a counter-pull 24 made of paper. This is in the FIG. 4 indicated schematically.
