[0041] According to an embodiment, the system for connecting the terrace boards to each other and to the base on which the terrace is placed, where the upper surface of the terrace boards 1 forms the usable surface of the terrace, wherein the terrace boards 1 are arranged at a preset distance s from each other, comprises a support board 2, a connector 4 and a fastening element 5. Said support board 2, preferably openwork, has open recesses formed between the converging side walls 2a, transverse to their common edge 2a. In one version of the invention, the recesses 3a are formed on the upper surface of the support board 2 at its corners as shown in FIG. 1 to FIG. 7, FIG. 15, and in the second version of the invention, the recesses 3b are formed in the side walls of the support board 2, between the upper and lower surfaces of the support board 2 as shown in FIG. 8 to FIG. 14, FIG. 16, FIG. 17. The connector 4 is in the form of a mushroom which contains a head 4a, a leg 4b and a through hole 4c passing through said head 4a and leg 4b, as shown in FIG. 18, 19. On the wall of the aforementioned opening 4c of the leg 4b, a support shelf 4c is formed for the fastening element 5, as shown in FIG. 19 to FIG. 23.

[0042] The supporting boards 2 are fixed to the lower surface of the terrace boards 1, for example with adhesive. The support boards 2 with the terrace boards 1 attached to them are laid on the terrace base at a pre-determined distance from each other and so that the recesses 3a, 3b of the adjacent sub-framework boards 2 form a socket 3 as shown in FIG. 1, FIG. 5, FIG. 5B, FIG. 12, FIG. 12B, in which the head 4a of the connector 4 is positioned and the leg 4b of the connector 4 is positioned between adjacent support boards 2. The fastening element 5, for example a screw, is positioned in the hole 4c of the connector 4 and with one end rests against the support shelf 4c in the hole 4c and with the other end is detachably fixed to the base on which the terrace is placed, for example screwed to the base, as shown in FIG. 2, FIG. 3, FIG. 9, FIG. 10. The recesses 3a, 3b are shaped in such a way that the connector 4 can be moved in the socket 3 along the gap s between the side walls of the adjacent support boards 2 to a position in which the head 4a of the fastening element 4 leaves the recess 3a, 3b of the socket 3 of the respective adjacent boards 2, as shown in FIG. 5, FIG. 5B, FIG. 12, FIG. 12B.

[0043] The fastening element 5, for example a screw, has a length n not greater than the height h of the fastening element 4, as shown in FIG. 6, FIG. 7, FIG. 11, FIG. 13, FIG. 14, FIG. 20, FIG. 21, which allows it to be left free in hole 4c during installation and removal of terrace boards 1.

[0044] The base on which the terrace is placed can be, for example, adjustable supports, stands, etc.

[0045] An example of terrace installation is as follows.

[0046] Support boards 2 are attached to the underside of the terrace boards 1 using adhesive, for example, so that the support board 2 does not project beyond the terrace board 1. Subsequently, on the prepared base of, for example, brackets, which are positioned at the corners of the support boards 2 and adjusted in height according to the design, the first support board 2 is laid with the terrace board 1 attached to it and connectors 4 with fastening elements 5, for example, with screws, are inserted in the recesses 3a/3b, and then further support boards 2 with attached terrace boards 1 are laid in the corners of the first support board 1 by moving the connector 4 in the gaps s between the adjacent support boards 2. Once the support boards 2 have been laid with the terrace boards 1 attached, the leg 4b of the connector 4 is inserted into the gap formed between the corners of the adjacent support boards 2, the head 4a of the connector 4 rests in the socket 3 formed by the 3a/3b recesses of the adjacent support boards 2, and the fastening elements 5 are then screwed to the base, for example to the brackets. The screwed-on fastening element 5 rests with its upper end against the supporting shelf 4c in the hole 4c of the connector 4.

[0047] Removal and replacement of terrace board 1 is done in reverse order of installation. First, the fastening elements 5 are unscrewed and left in the holes 4c, and then the connectors 4 are slid into the gaps s between the side walls of the adjacent support boards 2 so that the heads 4a of the connectors 4 leave the recesses 3a/3b of the dismantled terrace board 1. In place of the terrace board 1 that has been removed, a new terrace board 1 is inserted with the support board 2 attached to it, and then the connectors 4 are moved along the aforementioned gaps s to the sockets 3 and the fastening elements 5 are screwed to the substrate, for example to the brackets.
