Floor or wall covering system with laying units which can be combined in a modular manner
Surface laying unit ( 100 ) for laying with other surface laying units ( 100 ) on an underlying surface ( 300 ), wherein the surface laying unit ( 100 ) has a useful layer ( 102 ) and a connecting structure ( 104 ) which is provided directly on an underside of the useful layer ( 102 ) and which is designed for connecting to the underlying surface ( 300 ).
1. An arrangement for forming a covering on a substrate, wherein the arrangement comprises:
a plurality of substrate laying units, which can be laid together on the substrate to cover the substrate and can be connected to the substrate,
wherein one substrate laying unit comprises:
a stability layer, which is rigid in a board-like manner, for stabilizing a surface laying unit, which can be attached above the stability layer; and
a connecting structure, which is attached directly to an upper side of the substrate laying unit and is configured for connecting to the surface laying unit, wherein the connecting structure does not comprise a portion of a hook-and-loop fastener;
wherein an underside of the substrate laying unit opposite the upper side is configured for connecting to the substrate;
wherein a first side face of the stability layer comprises a first engagement element, and a second side face of the stability layer comprises a second engagement element, complementary to the first engagement element, wherein the first engagement element can be connected to a corresponding second engagement element and the second engagement element can be connected to a corresponding first engagement element of corresponding substrate laying units;
a plurality of surface laying units which are provided separately from the substrate laying units and are configured to cover the laid substrate laying units, wherein one surface laying unit comprises:
a wear layer, wherein the wear layer is produced from solid wood, has a thickness in a range between 0.5 mm and 4 mm, and is formed as a board;
a further connecting structure, which is attached directly to the underside of the wear layer and is configured for detachably connecting the surface laying units to the substrate laying units,
wherein the further connecting structure does not comprise a portion of a hook-and-loop fastener.
2. The arrangement according to claim 1 , wherein a side face of the wear layer is provided at least partially with the connecting structure, so that laterally adjacent surface laying units are connected to each other via the connecting structure when in the laid state.
3. The arrangement according to claim 1 , wherein a main surface of the surface laying unit has an area in a range between 0.001 m 2 and 0.5 m 2 .
4. The arrangement according to claim 1 , consisting exclusively of the wear layer and the connecting structure, or consisting exclusively of the wear layer, the connecting structure and a protective coating.
5. The arrangement according to claim 1 , comprising a further wear layer, which is arranged opposite the wear layer, separated by the connecting structure, so that the surface laying unit is configured as a reversible covering.
6. The arrangement according to claim 1 , wherein the wear layer comprises a hard covering layer and a sound-absorbing structure, which is attached directly to a main surface of the hard covering layer and is configured for damping sound when the hard covering layer is loaded with a sound-generating load; wherein the hard covering layer is formed as a surface layer.
7. The arrangement according to claim 1 , wherein the stability layer directly borders the wear layer.
8. The arrangement according to claim 1 , wherein the stability layer is formed as a fibre layer or as a fibre mat and is selected from a group which consists of a glass fibre mat and a carbon fibre mat.
