Description

[0017] The invention and other advantageous embodiments and developments of the same are described and explained in more detail below using the examples depicted in the drawings. The features to be inferred from the description and the drawings can be applied individually or in any combination in accordance with the invention. They show:

[0018] FIG. 1 a schematic sectional depiction of the carrier plate in an installation position for decoupling a surface covering from a supporting surface, and

[0019] FIG. 2 a schematic view of the carrier plate according to FIG. 1.

[0020] FIG. 1 shows a schematic sectional view of a carrier plate 11, which is depicted in a top view in FIG. 2. This carrier plate 11 consists of a film-like plate 12 made of plastic, which has a plurality of protrusions 14. These protrusions 14 are formed on both sides relative to a central plane 16, wherein the central plane 16 corresponds to the plane of the film-like plate 12 in the unfinished state. The protrusions 14 are thus formed alternately to form a first plate side 17 and a second plate side 18 of the film-like plate 12. The protrusions 14 and recesses 19 are arranged alternately in rows and columns. This emerges from the top view in FIG. 2. Along a first diagonal line 21, recesses 19 are provided. Between two recesses 19, a crosspiece 25 extends, which is preferably located in the central plane 16. In a further diagonal 22, offset by 90 to diagonal 21, protrusions 14 are lined up. Between two protrusions 14, a crosspiece 25 extends, which is preferably located in the central plane 16.

[0021] Due to the formation of protrusions 14 from the central plane 16 on both sides, horizontally formed support sections 23 arise in the central plane 16 seen in the section view. These support sections 23 surround the protrusions 14 annularly when changing from one plate side 17 to the other plate side 18. Seen in the top view, a star-shaped section 24 arises due to the protrusions 14 on both sides of the central plane 16 and the alternately arranged protrusions 14 and recesses 19 through the crosspieces 25. This preferably also merges with the crosspieces 23.

[0022] On a first plate side 17, an adhesion-enhancing layer 26 is provided. This layer 26 follows the contour of the first plate side 17 and preferably covers it completely. This layer 26 can be glued or laminated or welded on. Preferably, the adhesion-enhancing layer 26 consists of a fleece, in particular made of polypropylene or polyethylene. Alternatively, a preferably fine-meshed woven fabric, a knitted fabric, a textile material or a perforated fleece or a perforated felt can be provided as the adhesion-enhancing layer 26.

[0023] A further layer 29 is provided on the second plate side 18 on the front sides 28 of the protrusions 14. This layer 29 spans over the recesses 19 formed between the protrusions 14. This further layer 29 can be a net-like fabric, a fine-meshed fabric, a perforated fleece or similar. This further layer 29 is glued or welded to the front sides 28 of the protrusions 14.

[0024] The carrier plate 11 is used, for example, to decouple a surface covering 31 on a supporting surface 32. This is depicted in FIG. 1, for example. The carrier plate 11 is placed on the second side of the plate 18 on the supporting surface 32. Alternatively, this further layer 29 can be adhered to the supporting surface 32. Only a small amount of adhesive is applied, such that the recesses 19 remain free of adhesive or mortar.

[0025] Adhesive or mortar 34 is applied on the opposite first plate side 17 in order to fix the surface covering 31 to the carrier plate 11. The surface covering 31 can be formed from individual tiles or slabs, but also as a laminate made of resin or similar.

[0026] The carrier plate 11 has an increased load capacity or payload due to the plurality of protrusions 14 formed out of the central plane 16. Preferably, 9,000 protrusions per square metre or more than 20,000 protrusions per square metre are provided. The gradient of the conical wall sections of the protrusions 14 runs to a vertical of the central plane 16, preferably in a range between 10 and 20. The protrusions 14 extending on both sides opposite the central plane 16 have a height of less than 5 mm. Preferably, the height of the protrusions on both sides of the central plane 16 is the same.
