Description

DESCRIPTION

The present invention relates to the field of systems for covering or covering surfaces, floors, terraces or walkways, at least able to be driven by pedestrians, more particularly floor-type or floor-slab systems, and object a support block comprising shims integrated in its structure.

Numerous covering systems, circulable or not, of the slab type, grating type or stud floors are already known, in which cover elements in the form of rectangular or square plates are arranged on individual pads, generally placed on a sealing liner. each stud comprising at least one head with a support surface and a base forming a base (see for example EP 0 259 237, WO 2008/105012, EP 1 678 392).

Each cover element can be based directly on two, three, four or more studs depending on its shape, its location, its size and the nature of the studs.

These cover elements can also be based indirectly on these pads by means of joists or a supporting frame. Conversely, each stud can serve as support for two, three or four rectangular or square slabs depending on its position in the covering system, or a latch in the case of indirect support.

The adjustment of the height position of each pad, that is to say the distance between the support surface of the head and the surface on which the pad considered, is adjustable by action on the adjustable connection between the head and the base, usually of the type threaded connection or notches.

It may happen that the stud rests on a non-planar and / or non-horizontal surface so that the support surface of the head is inclined.

It also happens frequently that the covering elements have different thicknesses and / or have thickening or burrs at the edge areas intended to bear on the heads of the studs, resulting in a shoulder or similar inequality between adjacent elements worn. by the same stud, causing aesthetic defects.

In all these situations, cited only as examples, there is a need to individually adjust the height of each cover element so that it is flush with neighboring elements and abutting with him, carried by the same pad.

To meet this need, the traditional solution and generally implemented on site, is to slip wedges between the pad head and the element or the cover elements (s) below. It is necessary to do this to have a set of wedges adapted and available on site.

However, for reasons of cost, ease and availability, waste and scrap are generally used as wedges, which over time is not a satisfactory solution and does not meet the recommended laying rules. (possible collapse due to compression or breakage of the material of the improvised hold).

Another widespread use, to have wedges on site, is to remove pieces of wall studs with a hammer. However, this practice can lead to additional costs and seriously compromise the structural integrity of the pads because of the removed material, but also cracks possibly generated.

The present invention aims to provide a simple solution, practical and not very tedious, and if possible inexpensive, to meet the aforementioned need. For this purpose, the subject of the invention is a support pad for slab-type covering elements or the like, each pad being constituted by at least two pieces assembled together, directly or indirectly, namely a head providing a support surface and a support surface. base forming support base, the position in the height of the support surface being adjustable by adjusting the connection link, for example by screwing or by notching, between these two component parts, pad characterized in that it comprises at less a breakable portion formed integrally with at least one of the two aforementioned component parts, or with at least a third intermediate piece forming an assembly part and / or adjusting member, where each breakable part is suitable and intended to cooperate, after separation with the pad head to form a raised or prominent local support zone of a given height with respect to the support side. The invention will be better understood, thanks to the following description, which refers to preferred embodiments, given by way of non-limiting example, and explained with reference to the appended diagrammatic drawings, in which:

Figure 1 is a perspective view and in the disassembled state of a support pad in two parts according to a first embodiment of the invention;

FIG. 5 is a partial view in side elevation of a covering system comprising at least one stud of the type shown in FIG.

FIGS. 6 to 8 are perspective views respectively illustrating, with respect to the second and possibly first embodiments illustrated in FIGS. 1 to 5, alternative embodiments of a pad head (FIG. 6), a third piece forming a control member (Figure 7) and a base (Figure 8).

FIGS. 1, 2 and 5 illustrate a support pad 1 for covering elements 2 of slab type or the like, each pad 1 consisting of at least two pieces 3, 4 assembled together, directly or indirectly, namely a head 3 providing a support surface 3 'and a base 4 forming a support base, the position in height of the support surface 3' (on which the elements 2 rest) being adjustable by adjusting the connection connection, for example by screwing or by notch between these two component parts 3 and 4.

According to the invention, said stud 1 comprises at least one breakable part 5, 5 ', 5 ", 5'", formed in one piece with at least one of the two aforementioned components 3 and 4, or with at least one third intermediate piece 6 forming an assembly piece and / or adjusting member, the or each breakable part 5, 5 ', 5 ", 5'" being adapted and intended to cooperate, after separation, with the stud head 3 (by placing on the latter) to form a local support zone 7, elevated or prominent with a height h determined relative to the support surface 3 '

Thanks to the invention, the worker or the operator always has on site at least one structural element 5, 5 ', 5 ", 5' 'integrated in a stud 1 as a breakable part and configured to serve wedge height adjustment in relation to the pad head 3, for a slab 2 or the like.

This or these portion (s) 5, 5 ', 5 ", 5'" is (are) manufactured with the part 3, 4, 6 to which it (they) is (are) integrated (s) structurally, thus linking them captively to the part 3, 4, 6 concerned, while allowing their easy separation and without compromising the function or the cohesion or strength of this piece.

Advantageously, the or each breakable portion 5, 5 ', 5 ", 5'", intended to form a height adjustment shim, is substantially in the form of a wafer and consists of a peripheral or end portion a wall, a wing or a similar structural part of one of the constituent parts 3, 4, 6.

Preferably, the support stud 1 comprises several breakable parts 5, 5 ', 5 ", 5'", possibly formed on several of the constituent parts 3, 4, 6 of the stud 1. These different parts 5, 5 ', 5 ", 5 "" may constitute, after separation from the part (s) 3, 4, 6 concerned (s) and establishment on the pad head 3, shims providing local support areas 7 of different heights h or not, preferentially calibrated and with upper bearing surfaces 7 'parallel to the support surface 3' of the corresponding head 3 receiving them.

The different wedges 5, 5 ', 5 ", 5'" in the form of platelets may all have the same thickness and / or provide, after placement on the pad head 3, the same elevation height h (FIGS. 6 to 8), or not (Figures 2, 3 and 5).

Similarly, the thickness of the same wedge 5, 5 ', 5 ", 5"' may be uniform or may vary, for example gradually to present in section a wedge shape.

Of course, it is possible to stack several shims to achieve a significant elevation.

As shown in FIGS. 2A, 2B, 3A and 3B, each breakable part intended to form a wedge 5, 5 ', 5 ", 5"' may bear a marking or numerical indication 8, for example in relief and molded in the mass, corresponding to the height of elevation h provided by the wedge it forms after its introduction on the head 3.

The pad head 3 may have a support surface 3 'continuous and flat over its entire extent (upper wall full).

However, for reasons of manufacture, optimization of the ratio [mechanical resistance / quantity of material], optimization of the ratio [surface area of 3 '/ weight of the head 3], or of construction (material connection with the or the threaded sleeve 16, 17), the pad head 3 often has a surface configuration and a discontinuous surface structure, with for example recessed sites 10 and projections 10 'protruding.

In this case, it can be advantageously provided, as shown in particular in FIGS. 2A, 2C, 3C and 4, that each breakable portion 5, 5 ', 5 ", 5"', preferably in the form of a wafer of uniform thickness or no, comprises formations 9 and / or sites 9 ', male or female, suitable and intended (e) s to cooperate and to engage with sites 10 and / or formations 10' complementary present at the level of the surface of the stud head 3 concerned, this engagement being preferentially self-locking in the plane of the support surface 3 '.

The pad head 3 may, for example and as shown in FIGS. 2, have a central portion 14 with a substantially continuous wall, this central portion being surrounded by a hollow peripheral ring 14 'whose outer peripheral edge 14 "is connected to the central portion 14 by reinforcing fins 10 'The upper edges of said fins and the peripheral edge contribute to the definition of the support surface 3' with the central portion 14.

These reinforcing fins thus constitute protruding formations 10 '(with respect to the bottom wall of the crown 14'), separated by hollow regions constituting recessed sites 10, alternating with said fins.

The wedges 5 "'of FIGS. 2, 3 and 4 have a constitution, in particular on the underside, capable of cooperating by conjugation of shapes with the particular upper structure of the pad head 3, mentioned above, to provide a support zone 7 raised locally, with an upper bearing surface 7 'parallel to the support surface 3' (see Figure 5).

Thus, the fins 10 'of the head 3 engage in complementary sites 9' of the wedge 5 "', in the form of grooves, and the prominent material formations 9 of the wedge 5'" extend partially in the hollow regions 10 of the head 3, separated by the fins 10 '.

The remaining portion in the form of a thinner plate of the shim 5 "'then rests on the central portion 14 of the head 3.

The fins 10 'being divergent towards the outside, it leads to a blocking in position of the shim 5 "' on the head 3.

To take into account the random side of the need for the implementation of shims 5, 5 ', 5 ", 5"', it is advantageously provided by the invention in connection with the design and configuration of the part or parts (s) concerned 3, 4, 6 that each breakable part 5, 5 ', 5 ", 5"' is in the form of an extension or an outgrowth of one of the constituent parts 3, 4, 6 of the stud 1, this extension or this protrusion being preferably devoid of (e) functional and structural finality for the implementation of said stud 1, and being non-interfering (e) with the use of said support stud 1.

Thus, the support stud 1 can be used in an absolutely similar manner, that none, one or more of the breakable parts 5, 5 ', 5 ", 5"', or even all, are implemented (s) as hold (s).

According to a feature of the invention, given by way of practical examples of FIGS. 1, 2, 3A, 3B, 4 and 6 to 8, each breakable portion 5, 5 ', 5 ", 5"' is connected to the component part 3, 4, 6 which carries it by a weakened connection zone 11 constituting a preferred break line 11 ', being preferably formed in one piece with a positioning fin 12 of the stud head 3, a stiffening wing 13 of the base 4, a stabilizing wing of the base 4 (not shown) or a maneuvering formation 15 of an adjusting member 6.

Zone 11 may for example consist of a line of thinning of the material or, as shown in the above figures, two material bridges separated by a cut.

The separation of the wedges from parts 3, 4 or 6 is advantageously achievable manually or possibly at least with the aid of a hammer.

According to a first embodiment of the invention, the stud consists of two parts only, namely a head 3 and a base 4, joined together by a threaded connection with interlocking between two cylindrical barrels or sleeves 16 and 16 ' forming respectively part of the head 3 and the base 4, at least one breakable portion 5, 5 ', 5 "in the form of a wafer being formed integrally with the base 4 or the head 3.
