Technical field to which the invention relates

The present invention relates generally to the field of fence structures, for example for the partitioning of plots of land.

It relates in particular to a fence structure comprising concrete plates or the like.

Technological background

There are very many types of fencing structures intended to delimit or partition off plots of land.

In particular, fences are known which consist of vertical posts between which are disposed vertical shuttering plates, made of concrete or the like, for example a base plate associated with a higher grid, or even a superposition of several such plates.

In general, the posts include vertical rebates facing each other, intended to receive the lateral edges of the plates for holding them in position.

The corresponding plates have the general shape of a rectangular parallelepiped. They are produced by molding from a mixture of binder (for example cement), aggregates (for example sand or gravel) and water, possibly combined with adjuvants.

However, if they are robust and durable over time, fences of this type are generally not very aesthetic (in particular on the side of the pouring face of the concrete), which limits their attractiveness.

Object of the invention

In order to remedy the aforementioned drawback of the state of the art, the present invention provides a fence structure comprising at least two vertical posts spaced from one another and serving to support at least one concrete plate ( or similar) extending in a vertical plane, which concrete plate is delimited by:

- two front faces parallel to each other,

- an upper border provided with an upper edge,

- a lower border provided with a lower edge and which extends parallel to said upper border, and

- two lateral edges, mutually parallel, each provided with a lateral edge, said vertical posts each being provided with at least one rebate over at least part of their height, and two rebates facing said two posts serving as means for receiving the lateral edges of said concrete plate;

and this fence structure is characterized in that it comprises at least one facing element comprising a plate which covers one of said front faces of said concrete plate, which plate comprises:

- an upper edge provided with a square return wing covering at least partially said upper edge of said concrete plate,

a lower edge provided with a square return wing covering at least partially said lower edge of said concrete plate, and

- Two lateral edges which are situated at or substantially at the level of the lateral edges of said concrete plate, which lateral edges are housed in said rebate of said vertical posts.

Such a combination of characteristics makes it possible to improve the aesthetics of the fence structure by the presence of the facing elements which can be distributed at will, on one side and / or the other of at least some of the concrete plates. . In addition, such a fence structure is very simple to manufacture and assemble, the facing elements being able to be held against the associated concrete plate by their retention in the rebates of the posts, and by the presence of the upper return wing. and the lower return wing.

Other non-limiting and advantageous characteristics of the fence structure according to the invention, taken individually or in any technically possible combination, are the following:

- The facing element is made of cut and folded metal sheet whose thickness is between 0.5 and 1.5 mm, more preferably between 0.75 and 1 mm;

- the facing element is made of painted metal sheet;

- the tray of the facing element has through openings;

- Figure 7 is a partial sectional view illustrating an alternative embodiment of the facing element;

- Figure 8 is a sectional view which further illustrates an alternative embodiment of the facing element and the associated concrete plate.

The fence structure 1 illustrated in FIGS. 1 to 5 comprises vertical posts 2 spaced from one another, which are adapted to serve as support for concrete plates 3, at least some of which are associated with at least one facing element 4 .

The posts 2 are made of concrete or metal.

They comprise two longitudinal rebates 2a in opposition, which extend over at least part of their height, into which the lateral edges of the concrete plates 3 and of the facing element 4 possibly associated, are fitted, for their support. and keeping them in a vertical plane.

Each concrete plate 3 with the facing element 4 possibly associated is supported by the rebates 2a opposite two posts 2 consecutive.

Here, the posts 2 have a generally square horizontal section; but this section can be arbitrary.

As can be seen in FIG. 3, the rebates 2a of the posts 2 have a square or rectangular section delimited by a bottom 2a1 and two parallel lateral sides 2a2 and 2a3.

Each concrete plate 3 is in the general shape of a parallelepiped delimited by:

two front faces 31 parallel to each other, which define a thickness d between them,

an upper edge 32 provided with an upper edge edge 33 at the end,

a lower edge 34 provided with a lower edge 35 at the end, and which extends parallel to said upper edge 32, and

- two side edges 36, mutually parallel, each provided with a side edge 37 at the end.

These concrete plates 3 are obtained in a conventional manner by molding a mixture of cement, sand and / or gravel and water, with the integration of a metal frame or suitable reinforcing fibers.

As an indication, the length of the concrete plates 3 can be between 1 m and 2.5 m; their height can be between 0.15 m and 0.5 m; and their thickness d can be between 1.5 and 5 cm.

The facing element 4 is shown in isolation in Figure 6 and in association with a concrete plate 3 in Figures 1 to 5.

This facing element 4 is made of painted metal sheet, for example of stainless steel sheet, stainless steel sheet or zinc sheet, cut and folded, the thickness of which is between 0.5 and 1.5 mm, preferably still between 0.75 and 1 mm.

The facing element 4 comprises a plate 41 of generally rectangular shape whose length and width dimensions correspond, or correspond approximately, to those of the front faces 31 of the concrete plates 3.

The plate 41 of the facing element 4 has an internal face 41a and an external face 41b; and it is delimited:

- by an upper border 411 provided with an upper edge 411 a,

- by a lower edge 412 provided with a lower edge 412a, and

- by two lateral edges 413 and 414 each provided with a lateral edge 413a and 414a.

The upper edge 411a of the upper edge 411 is provided with a wing returning to the square 42 which extends over a length 11, here less than half the thickness d of the concrete plate 3; and the lower edge 412a of the lower edge 412 is provided with a return wing at the square 43 which extends over a length I2, here also less than half the thickness d of the concrete plate 3.

For their part, the lateral edges 413a and 414a are free, devoid of return or extension.

The two wings return to the square 42 and 43 extend from the edges 411a and 412a, on the side of the internal face 41a of the plate 41.

The association between the concrete plate 3 and the facing element 4 is effected by pressing the internal face 41a of the facing element 4 against one of the end faces 31 of the concrete plate 3, with:

the return wings 42 and 43 partially covering, respectively, the upper edges 33 and lower 35 of said concrete plate 3, and

- The two side edges 413a and 414a being located at, or substantially at, the side edges 37 of said concrete plate 3 (Figures 3 and 5).

The concrete plate 3 and its facing element 4 are then mounted on the vertical posts 2 in a conventional manner, by integration of their lateral edges 36-413a and 36-414a in the reception rabbets 2a; the parallel lateral sides 2a2 and 2a3 of these receiving rabbets 2a then serve as lateral blocking members which ensure that the facing element 4 pressed against the facing front face 31 of the concrete plate 3 is maintained, without requiring other means of assembly.

The width of the rebate 2a, that is to say the distance between the two lateral sides 2a2 and 2a3, is adapted accordingly.

Only one of the two end faces 31 of the concrete plate 3 can be provided with a facing element 3; but the two end faces 31 of the same concrete plate 3 can also be equipped, because of the lengths 11 and I2 of the flanges 42 and 43 less than half the thickness of the concrete plates 3.

The external face 41b of the plate 41 can receive any desired decoration or surface coating, depending on the desired aesthetic appearance; in the same vein, the plate 41 of the facing element 4 may include perforations, openings or through holes, in order to obtain any desired decorative or aesthetic effect.

As illustrated in FIGS. 1 and 4 in particular, the vertical posts of the fence structure 1 can accommodate several superimposed concrete plates 3, held in the rebates 2a.

Then, at least some of these concrete plates 3 may have a facing element 4 on one of their front faces 31, or both. The wings return to the square 42 and 43 then form spacer members between two superimposed concrete plates 3.

FIG. 7 illustrates an alternative embodiment in which the wing returns to the square 42 'which extends the upper edge 411a of the plate 41 of the facing element 4' extends over the entire width of the upper edge 33 of the concrete plate 3 (that is to say over the entire thickness of the concrete plate 3), this return 42 'being itself extended by an end wing 44 extending parallel to said plate 41. This end wing 44 then covers the upper edge 32 of the front face 31 of said concrete plate 3 which is opposite to that covered by said plate 41.

Such a facing element 4 ′ can for example be used for a concrete plate 3 located the highest between two vertical posts 2, in order to obtain an optimal finish for its upper edge 32. Such a structure also makes it possible to improve the assembly between the facing element 4 'and the associated concrete plate 3.

One can also consider equipping all the 4 ’facing elements in this way with the same fence structure, and also equipping the lower edge 412 in the same way of the 4’ facing elements.

FIG. 8 illustrates another variant embodiment in which:

the return wing 42 ′ which extends the upper edge 411a of the plate 41 of the facing element 4 ″ is extended by an end wing 44, in a manner identical to the embodiment of FIG. 7, and

- The return wing 43 ′ which extends the lower edge 412a of said plate 41 has a crushed fold 45 (that is to say a 180 ° fold).

This crushed fold 45 is oriented on the side of the internal face 41a of the plate 41, and its length is less than that of the associated return wing 43 ’; it gives a double thickness at the end of the return wing 43 ’, in particular to improve the rigidity of the 4” facing element.

Yet in another alternative embodiment, the return wing 42 which extends the upper edge 411a of the plate 41 of the facing element has a crushed fold 45 identical or similar (as illustrated in the lower part of FIG. 8 on the facing element 4 ”').

In the presence of such a crushed fold 45 on the upper return wing 42 and / or on the lower return wing 43 ', the upper edge 33 and / or the lower edge 35 of the concrete plate 3' comprises ( nt) advantageously a rebate 38 which extends over their entire length, formed on the side of the front face 31 of said concrete plate 3 ′ opposite to that covered by the plate 41 of the facing element 4 ”, 4 ′ ”(Figure 8).

In FIG. 8, the upper edge 33 and the lower edge 35 of the concrete plate 3 ′ have such a rebate 38.

This rebate 38 is arranged to receive and accommodate the crushed fold 45 in correspondence of the lower and / or upper return wings of the associated facing element. It allows this associated facing element 4 ”, 4” to be locked in position; and it also avoids excess thickness when overlapping concrete slabs.
