Support system for raised flooring and flooring obtained by this support system

Abstract

The present invention refers to a support system for raised flooring made with wooden boards and to the relative flooring obtained by this system. The supporting system is used for obtaining a floor with boards made of wood or similar material wherein the floor is elevated with respect to the reference ground. The supporting system includes a trampling plate and at least three supporting feet fixed to the plate in order to support the plate with respect to the reference ground.

5. Supporting system according to claim 2, wherein the at least one recessed seat comprises four recessed seats, said strip being fitted within one of said four recessed seats and additional strips being fitted within the other three of said four recessed seats.

6. Supporting system according to claim 5, wherein each of the four recessed seats is formed along each side of the at least one grid.

7. Supporting system according to claim 6, wherein the boards are fixed to the at least one grid by means of nails.

8. Supporting system according to claim 1, wherein the at least one grid (16) comprises corners which are sunken.

Description

(1) Further features and details of the invention will be better understood from the following specification that is provided by way of a non-limiting example, as well as from the annexed drawings, wherein:

(2) FIGS. 1, 2 and 3 are axonometric views of a flooring portion that takes advantage of a support system according to the invention formed by a set of plates resting on support feet;

(3) FIG. 4 is an exploded axonometric view of a plate with wooden boards, utilized to implement the support system in FIG. 1;

(4) FIGS. 5 and 6 are axonometric views of the plate in FIG. 4;

(5) FIG. 7 is a top view of the plate in FIG. 4;

(6) FIGS. 8 and 9 are side views of the plate in FIG. 7;

(7) FIG. 10 is a side view of the plate in FIG. 7, sectioned according to a transverse plane denoted by A in FIG. 7;

(8) FIG. 11 is a view of a detail of the plate in FIG. 7, denoted by B in FIG. 10.

(9) With reference to the annexed drawings, in particular FIGS. 1, 2 and 3, number 10 denotes a portion of flooring that takes advantage of a support system according to the invention for raised flooring and comprises supporting feet 12 and treading plates 14, exactly four, supported by said supporting feet 12.

(10) As shown in the FIGS. 4 to 11, each treading plate 14 comprises a grid 16 having a reticular structure and a substantially square shape with sunken corners 17, a seat being formed at each sunken corner for a stable connection with a supporting foot 12.

(11) Besides, a central hole 20 and four holes 18 are formed in the grid 16, each hole being formed at a corner of the grid 16.

(12) Each of the five holes 18, 20 is provided with suitable seats for the connection with a supporting foot 12.

(13) The conformation of the supporting feet 12 and the seats formed in the grid 16, as well as the mode of connection of the feet 12 to the grid 16 are already known and described in the following patent document: patent application No. 102015902350751, to which reference may be made for a better comprehension.

(14) Four longitudinal seats 22 are formed at the four sides of the grid 16, one seat for each side, in which strips 24 may be received, one strip for each seat 22.

(15) The strips 24 are made of wood; the function of the strips is the strengthening of the entire grid 16 and the avoidance of unwanted bending of the upper treading plane.

(16) Obviously, the strips 24 may be made also of steel or another rigid material.

(17) Six wooden boards 26 are fixed on the upper surface of the grid 16 and are fixed by nails 28 to the grid.

(18) In particular, the length of the boards 26 is equal to the length of the grid 16; likewise, also the whole width of the set of boards 26 covers the grid 16 entirely, without protruding.

(19) In this way, the six boards 16 cover the entire surface of the grid and even the angular empty portion corresponding to the sunken corners 17. Thus, the plate 14 has an upper surface which is perfectly square.

(20) As shown, in particular in FIGS. 10 and 11, the nails are hammered upwards in the bottom of the grid 16 and have a height less than the thickness of the wooden boards 26.

(21) In this way, the treading surface of the plates 14, namely the visible surface of the boards 26, is clean and free of bodies or elements.

(22) Pre-formed holes 30 are formed in the grid 16 to facilitate a correct positioning of the nails 28.

(23) The so-obtained elevated flooring 10 may be easily made through the support system according to the invention, which is a modular support system.

(24) The operator who has to assemble the flooring is not forced to fix wooden boards one after the other, but it is sufficient for him to fix the plates 14 to the respective feet since the boards 26 are already fixed to the grid 16.

(25) Also in the case of breakages in portions of the flooring, it is sufficient to lift the one or more plates 14 of the sector in question without having to first lift the wooden boards.

(26) According to a variant of the invention, a treading plate may comprise two or more grids on which wooden boards are fixed which cover, as a whole, the entire surface of the two or more grids.

(27) For example, the wooden boards may have a length greater than a single grid and cover in length the two or more grids which are covered in width by the set of the boards.

(28) In this way, the realization of the flooring may take place even more quickly by using larger plates.

(29) Other variants and embodiments are still possible which are to be considered as included in the scope of protection defined by the claims.

(30) For example, the conformation of the plates may be different from the square shape and may be rectangular or may have another shape provided that an optimum modularity is ensured.

(31) In addition, the number of wooden boards arranged on the grid can be different from six; despite the different number, but with different width, the wooden boards can still cover the entire surface of the grid.
