Pfilastersteine and surface coverings made therefrom, preferably composite of concrete blocks or natural stones are well known.

Also is already out of the document DE 31 44 559 A1 a wood paving stone is known, which has a smooth-ground surface serving as a running surface, wherein the edges bounding the surface side are broken and on the smooth surface side, a layer of a sealing agent is applied. The wooden paving stones are made of end-grain wood. The smooth bottom surface opposite pad bottom has cut longitudinal and transverse slots.

From the GB 422005 Furthermore, an integrally formed Holzpfilasterstein from forehead wood can be seen, which has lateral spacers or for laying in composite provided frontal recesses.

Based on this, it is an object of the present invention to provide a Holzpfilasterstein and a Holzfilächenbelag, which is flexible in addition to a long service life for a variety of applications. The object is achieved on the basis of the features of the preamble of claim 1 and 15 respectively by its characterizing features.

The essential aspect of Holzpfilastersteins invention is the fact that the base body is constructed multi-layered, wherein the base body has an upper plate-shaped or block-like wood layer and at least one further, the underside of the body forming the lower support layer, which are directly or indirectly connected to each other. Particularly advantageous allows the multi-layer structure of the body comprising an upper plate-shaped or block-like wood layer and a base layer allows the production of individually adapted to the different conditions of use Holzpfilastersteinen. Under Holzpfilasterstein in the context of the invention, a laying paving stone is understood here, the composite can be laid, which is constructed in several parts or multi-layered and the tread-forming plate-shaped or block-like wood layer of a solid piece of wood is preferably formed integrally or in one piece. Furthermore, the wood paving stone according to the invention is characterized by a long service life and can be laid quickly and easily on a variety of substrates. The laying in conjunction with joints also enables optimal drainage of a wood surface covering produced from the wood paving stones according to the invention. Particularly advantageously, the layers mentioned can be produced independently of one another and can then be joined together to produce the wooden paving stone. The upper layer of wood and the lower base layer can either be arranged congruently one above the other or offset from one another, so that a ready-to-lay wooden paving stone is formed. Such a wooden pavement is particularly suitable for heavy traffic.

The upper plate-like or block-like layer of wood is particularly advantageously made of an impregnated wood, preferably permafrost, robinia or acacia, wherein the upper layer of wood is made of longitudinal wood, preferably in one piece or in one piece.
