## Abstract

The present disclosure refers to a construction set for covering a substrate, in particular a floor substrate, comprising plate structural elements for covering the substrate, and connecting elements for joining together the neighbouring plate elements, optionally while preserving a fixed distance between them to form a dilatation gap, characterized in that the connecting elements (4) comprise at least two, located on a base (5), assembly protrusions (6) seated in the neighbouring, connected plate elements (1) equipped on their substrate side with identical assembly sections (2) comprising at least one drilled assembly hole (3), and in the holes (3) there are seated, by means of the assembly protrusions (6), the connecting elements (4) joining the neighbouring plate elements (1).

## Claims

### Claim 1

A construction set for covering a substrate, in particular a floor substrate, comprising plate structural elements for covering the substrate, and connecting elements for joining together the neighbouring plate elements, optionally while maintaining a fixed distance between them to form a dilatation gap, characterized in that the connecting elements comprise at least two, located on a base, assembly protrusions seated in the neighbouring, connected plate elements equipped on their substrate side with identical assembly sections comprising at least one drilled assembly hole, and in the assembly holes there are seated, by means of the assembly protrusions, the connecting elements joining the neighbouring plate elements, that preferably are cuboidal, having the identical thickness, wherein the length and/or width of the plate elements is a function of a value which is—upon subtracting the width of the dilatation gap—a distance between the two neighbouring assembly sections located along the same flank of the plate element, and optionally also of the width of the dilatation gap, so that the length and/or width of the plate elements is determined by the relationship A+n(A+C), where n is equal to 0 or is a positive integer, and moreover along the flank of the plate element, a position of the assembly sections is determined according to the relationship ½ A+n(A+C), so that each assembly section is within a constant distance from the nearest edge of the plate element, in which it is located and in a fixed position in relation to the nearest assembly section of the neighbouring plate element, wherein the construction set comprises the plate elements having dimensions determined for at least some values of the parameter n and comprises also the assembly sections with positions determined for at least some values of the parameter n.

### Claim 2 (depends on 1)

The construction set according to claim 1, wherein each assembly section comprises one assembly hole or it is composed of two or three or four assembly holes.

### Claim 3 (depends on 1)

The construction set according to claim 1, wherein the assembly holes are drilled in a shape of hollow cylinders that are perpendicular to the operational surface of the plate element, and the assembly protrusions are in a shape of cylinders or in a shape of polyhedrons inscribed into cylinders having a diameter corresponding to a diameter of the assembly holes.

### Claim 4 (depends on 1)

The construction set according to claim 1, wherein each assembly section comprises one assembly hole, and the connecting element is equipped with two assembly protrusions.
