The The present invention relates to a parquet element according to the preamble of claim 1.

From the DE 100 45 475 A1 is a parquet element for producing a parquet floor in damp rooms, z. As bathroom, basements and the like., Known in which a surrounding the parquet element projection is formed by a predetermined distance of the edges of a support plate with respect to a utility plate mounted thereon. On the underside of the support plate milled grooves for inserting a Kreuzfugenverbinders are parallel to the outer edges in a formed of four flush juxtaposed parquet elements Nutenviereck available. By the projections of the support plates, a joint bottom is formed, wherein the adjacent edges of adjacent support plates run centrally along the joint bottom or can conclude with an edge of the useful plate.

From the DE 199 41 284 A1 is a parquet floor formed of parquet elements for wet rooms known, the Nutzplatte. Has material recesses along the upper edges, so that in the installed state at the boundaries of the parquet elements results in a pocket-shaped, formed by the utility plate gap. The underlying support plate has on opposite sides of the Parkettelements parallel to the utility plate extending, complementary to each other formed recesses and projections for nesting other parquet elements.

The According to the prior art known parquet elements require one high production costs, are cumbersome to lay or for making a sturdy and durable parquet floor unsuitable for damp areas.

task The invention is to overcome the disadvantages of the prior art. In particular, a parquet element for the production of a parquet floor be specified for wet rooms, the cost-effective, quick and easy to lay and very robust and durable is. Furthermore, a method for producing a parquet floor be specified from the parquet elements.

These The object is solved by the features of claims 1 and 9. Expedient embodiments of the invention result from the features of claims 2 to 8 and 10 to 12th

To According to the invention, the carrier plate along a first side with respect to the Nutzplatte linking recesses and complementary thereto along the opposite second side, with respect to the utility plate outwardly projecting Chaining projections on. The utility plate covered in particular those provided on the first side of the support plate Chaining recesses, but not on the second side to the outside projecting interlinking projections. Through the linking recesses and -vorsprünge the parquet elements are easy and move quickly to a parquet floor. The parquet elements According to the invention along the connecting sides fixed relative to each other, so that the parquet floor is not can warp or break along the connecting lines. By the provision of interlinking recesses and projections on the support plate of the parking element itself, are none other materials and tools for connecting the parquet elements necessary. This allows an uncomplicated and cost-effective production of a robust and durable parquet floor.

To a preferred embodiment of the invention, the carrier plate along a third side with respect to the utility plate linking recesses and complementary thereto along the opposite fourth side, with respect to the utility plate outwardly projecting Chaining projections on. That allows one all-sided concatenation of the parking element according to the invention. A parquet floor produced with it is particularly resistant to deformation.

To A preferred embodiment of the invention is the Nutzplatte connected by epoxy resin to the carrier plate. epoxy resin is impermeable to water. In the case of parquet elements laid parquet floor can therefore no moisture to the support plate penetrate. This prevents the bottom from the bottom swells.

The Support plate is a multi-layer glued multiplex board. The multiplex panel is a veneer plywood panel, which by pressing several veneer layers with adhesive or waterproof glue is made. Advantageously, the plurality Veneer layers of the multiplex board cross-bonded, d. H. the single ones Veneer layers are with their grain by 90 ° or others Angle offset from each other glued. This can, if necessary due to moisture gain or decrease, shape changes be avoided the Parkettelements.

A preferred embodiment of the invention provides that the support plate is glued on its underside opposite the utility plate with a counter-pull. The glue is preferably a water-resistant wood glue of the stress group D4, which is suitable for use in the interior or exterior for the gluing of heavily exposed to moisture wood suitable is. This provides further protection against moisture acting on the parquet. Advantageously, the counter-pull with its grain is mounted substantially perpendicular to the grain of the useful plate on the support plate. This further increases the dimensional stability of the Parkettelements.

To a further particularly preferred embodiment of the invention jumps an edge of the support plate from which the linking projections with respect extend the Nutzplatte, with respect to the Nutzplatte to a predetermined distance to the outside. Later Concatenating the parquet elements, the utility plates are not directly together. The wood of the useful plate can absorb moisture expand and contract without creating tensions. The epoxy resin used to connect the utility and carrier plate is in this respect exposed to little or no shear. This further increases the stability of the Parkettelements.

The complementary linking projections and linking recesses are designed in the manner of a dovetail joint. There are from the support plate with respect to the Nutzplatte after externally projecting interlinking projections outside areas wider than on the inside lying areas. The projections and recesses engage in such a way that a chaining or releasing the connection two parquet elements only by vertical nesting or Lifting is possible. In a through the parquet elements However, in the linked state level are all parquet elements firmly connected.

A Further embodiment of the invention provides that the linking recesses and -vorsprünge in plan view have a rounded contour. This facilitates the production of the linking recesses and -vorsprünge. It also makes their strength elevated.

To Another requirement of the invention is a parquet floor for Moisture dreams of a variety of chained together manufactured parquet elements according to the invention. The parquet elements can only in vertical Direction are moved and are otherwise fixed. In case of Unevenness of the soil can be caused by the useful plates formed levels of individual parquet elements against each other be offset in the vertical direction. The useful plates of the higher standing parquet elements can subsequently be sanded off to get a flat parquet floor.

To A particularly preferred embodiment of the invention are between the useful plates of the parquet elements up to the carrier plate reaching joints formed. A width of the joints is determined by the predetermined distance determined with which the edge of the support plate projects. The height of the adjoining utility plates of the linked parquet elements defines the height of the Joint flanks. The joint floor has a closed, to the adjacent Joint flank reaching surface. Unlike for example adjoining half-joints are not exposed Scratches, due to the moisture between the support plates can penetrate. The given distance of the edge can be arbitrary be elected. It can be 0 to 10 mm, preferably 4 to 6 mm, amount. Joints allow the wood of the slab to change with changing To expand and contract and reduce room humidity thus tensions in the utility plate. The joints are expediently filled with an elastic grout. In which Grout agent is preferably a water-resistant polymer MS-based (modified silane). The MS polymer is a water-resistant Sealant, without the application of another bonding agent is universally applicable as an elastic grout.

A parquet floor can be made of parquet elements by a process using the following steps:
Laying the parquet elements according to the invention by intermeshing the concatenation recesses and protrusions complementary to each other along the support plates along respective opposite sides,
Filling of joints formed between the boundaries of the useful plates of the parquet elements with a grouting agent,
Sanding the parquet floor after curing the grout, and
Sealing the parquet floor with an oil.

The Method can be used with the parquet elements of the invention very fast, easy and cost-saving be and allows in particular the production of a waterproof parquet floor.

One Embodiment of the invention will be described below explained in more detail by drawings. Show it:

1 Parquet elements according to the invention in a section-wise perspective view

2 according to the parquet elements 1 after nesting in a sectionwise perspective view,

3 a section of a parquet floor according to the invention in a perspective view,

4 the nested parquet elements 2 in a sectional perspective view from below,

5 a section of the parquet floor according to 3 in a perspective view from below and

6 a cross section of two inventive parquet elements in the vertical nesting.

1 shows the front of three parquet elements in a perspective view from above before their concatenation. Each parquet element has a z. B. 4 to 10 mm, preferably 5 to 7 mm, strong Nutzplatte 1 , a 6 to 12 mm thick support plate 2 and a 0.5 to 1 mm countermovement formed from a veneer 3 out. At the foreseen front and long sides of the three parquet elements are on the support plate 2 concatenation projections 4 and with respect to the utility plate 1 by a predetermined distance 5 formed outwardly projecting edges.

A grain of the usually made of hardwood from deciduous trees 1 of the Parkettelements runs substantially parallel to its long side. The utility plate 1 has a thickness of typically 4 to 10 mm, preferably 6 mm. The utility plate 1 is with the carrier plate 2 connected by means of a waterproof Epoxidharzschicht. The epoxy layer serves as a barrier to moisture penetration. The multi-layered cross-bonded multiplex carrier plate preferably has a thickness of 6.5 mm and is provided with a preferably 0.6 mm thick counter-pull 3 glued with a wood glue of stress group D4. Also, the wood glue prevents moisture from entering, so that swelling of the parquet floor from the underside is prevented. The z. B. made of real wood veneer counter-pull 3 is mounted so that its grain is substantially perpendicular to the grain of the useful plate 1 runs. The transversely aligned grains of the useful plates 1 , Carrier plates 2 and the counterpart 3 reduce the tensions that arise as a result of moisture absorption or loss in the parquet element and thus increase their robustness and dimensional stability.

2 shows three nested parquet elements in a perspective view. Between the parquet elements is a joint 6 educated. On the front side, the parquet elements can be a straight joint 6 form. But you can also, as in 3 shown to be linked to each other offset. A width of the joints 6 arises when nesting the parquet elements from the specified distance 5 , with which the edge of the carrier plate 2 with respect to the overlying utility plate 1 projects.

In 4 You can see three nested parquet elements from the bottom. The carrier plate 2 points next to the under the utility plate 1 projecting interlinking projections 4 also complementary to the Verkettungsvorsprüngen 4 trained linking recesses 7 on. The carrier plate 2 closes on the sides of the linking recesses 7 regarding the utility plate 1 at the same height.

5 shows a part of a laid parquet floor from the bottom. The rounded contour of the linking projections visible on the underside of the parquet floor 4 and recesses 7 in the longitudinal direction and at the butt sides in the transverse direction is always below the useful plate 1 educated. The joint 6 thus always have one with the carrier plate 2 formed closed joint floor.

6 shows a cross section of two inventive parquet elements in the vertical nesting. The in a second carrier plate 2 formed linking recesses 7 be in the chaining tabs 4 a first carrier plate 2 put a first Parkettelements. The predetermined distance 5 the first carrier plate 2 forms together with the height of the two adjacent Nutzplatten 1 the joint 6 out.

For the production of parquet floor is a variety of parquet elements by vertical nesting of the support plates 2 at the complementary formed Verkettungsvorsprüngen 4 and recesses 7 laid. By the manner of a dovetail connection formed Verkettungsvorsprünge 4 and recesses 7 the parquet elements are fixed relative to each other in the horizontal direction and can only lift vertically. Unevenness of the floor on which the parquet is laid, cause a vertical offset of the parquet elements. To compensate for this offset the Nutzplatten 1 sanded down to the same height after installation. The multi-layer glued Nutzplatten 1 , Carrier plates 2 and retreats 3 Prevent moisture ingress. The at the joints 6 the closed joint floor forming support plates 2 Prevent moisture from entering the underside of the parquet floor. The joint 6 are 0 to 10 mm, preferably 3 mm wide, but depending on the choice of the predetermined distance 5 , with the edge of the carrier plate 2 regarding the utility plate 1 outwardly projecting be wider or narrower.

After laying the parquet elements, the joints become 6 filled with a waterproof grout, a MS based polymer (modified silane). After the grout has hardened, the parquet floor will just get smudged fen. Finally, the parquet floor is sealed. For this purpose, an oil is used.
