This device comprises glue traps (16) for fixing a covering element (18) of a riser of the terrace and these glue traps (16) are shaped so that, when the element covering (18) is positioned in contact with the glue traps (16) and that the glue traps are filled with glue, the glue, on solidifying, forms fixing members which are glued, on the one hand, to the covering element (18) and mechanically anchored, on the other hand, inside the glue traps (16), thus making it possible to fix the covering element against the device.

Description

Device for a terrace block, block comprising such a device and installation of a terrace on blocks comprising floor elements supported by such blocks

The present invention relates to a device for a terrace pad. A terrace is an element of the architecture of a building (house, building ...) that is located outside of it. It is an external surface located on the ground floor or on one floor of the building.

Plot terrace installations are widely used because they allow rainwater to be drained easily. The principle is as follows: studs are installed, which are better known under the name of "terrace studs", to support floor elements, such as slabs, gratings, grids, artificial grass patches, or even wooden planks. In certain installations, the studs support joists on which the constituent boards of the floor are fixed. We then speak of studs for joists.

Generally, a terrace stud includes a flange connecting to the ground, a nut, a threaded head and a support plate for a floor element, such as a slab, a grate, a grating or a joist. In the case of slabs, the term "slab plate" is used more specifically. The threaded head is engaged inside the nut, and allows height adjustment by screwing or unscrewing.

In principle, it is customary to dress the risers of the terrace, that is to say the contours of the terrace, to hide the studs. Also, we use trim elements. One way of doing this is to fix the covering elements to what is called a lateral covering support, which is an accessory which is fixed by fitting onto the flange of the stud. The trim supports include a kind of rail allowing the vertical installation of a slab or a joist for the dressing of the riser.

The side trim panels are also fixed, at the top, to the floor elements by means of an added angle and screw-type fasteners.

Although this solution is generally satisfactory, the fact remains that the rails and angles used for fixing the side panels remain visible from the outside, which can annoy some owners of terraces. Until now, it has been proposed to hide the visible part of the rails with pebbles, plants or other decorative elements. However, this solution is not satisfactory in all configurations. Typically, when the terrace is built on a concrete slab, the aforementioned solutions for masking the visible part of the studs give a somewhat artificial, and therefore unsightly, appearance.

It is to these drawbacks that the invention intends to remedy more particularly, by proposing terrace studs, specifically designed to be able to bond the trim elements of the riser.

The problem of bonding is that we must glue two pieces of different materials here: The covering elements are most often made of ceramic (slabs) or wood (joists), while the studs are made of plastic, especially in polypropylene. Also, the bonding is not durable over time, in particular due to the external climatic conditions and the difficulty of finding an adhesive suitable for these two types of material.

To this end, the invention provides a device for a terrace stud, which is specific in that it includes glue traps for fixing a covering element for a riser of the terrace and in that the glue traps are shaped so that, when the covering element is positioned in contact with the glue traps and the glue traps are filled with glue, the glue, on solidifying, forms fixing members which are glued, on the one hand, to the covering element and mechanically anchored, on the other hand, inside the glue traps, thus making it possible to fix the covering element against the device.

Thus, the selected glue is specifically chosen to adhere to the material constituting the covering element (ceramic glue or wood glue). In practice, a strip of glue is affixed to the rear face of the covering element and the covering element is positioned against the glue traps. The glue is then removed by the contact pressure inside the glue traps. The glue will, on the one hand, adhere to the covering element and, on the other hand, fill the glue traps of the device. Once the glue has dried and solidified, there is a kind of glue pin inside each glue trap and this pin is mechanically anchored in the glue trap by the specific shape of the glue trap .

According to advantageous, but not mandatory, aspects of the invention, the device can include one or more of the following characteristics, taken in any technically admissible combination:

The device is a lateral covering support, which is an accessory designed to be removably attached to a flange of the stud.

Alternatively, the device is a flange connecting to the ground.

- According to another variant, the device is a support plate for a floor element.

The glue traps are T-shaped.

- At least one of the glue traps, preferably each glue trap, includes a bottom wall, to prevent the glue from escaping by gravity.

- At least one of the glue traps, preferably each glue trap, comprises an opening, through which the glue applied to the covering element can penetrate by gravity inside the glue trap.

Said opening is arranged opposite to the bottom wall.

The glue traps extend over all or part of the circumference of the device.

The glue traps are organized in one or more rows.

The glue traps are organized in two rows that extend in non-parallel directions.

The device comprises a tongue forming with the glue traps a rail for positioning the covering element.

The tongue is divisible.

The invention also relates to a patio block, comprising a device as defined above.

The invention finally relates to a terrace installation on studs, comprising floor elements supported by studs according to the definition above.

Advantageously, each covering element is kept fixed between two pieces of a stud at least, respectively between a flange connecting to the ground or a lateral covering support fixed to the flange and a support plate for a floor element.

The invention and other advantages thereof will appear more clearly in the light of the following description of four embodiments of a device (or accessory) for a patio block, in accordance with its principle, given only by way of example and with reference to the appended drawings in which:

Figure 1 is a perspective view of a terrace installation on studs, comprising floor elements supported by studs according to the invention;

Figure 2 is an enlarged view of Box II in Figure 1;

Figure 3 is a sectional diagram illustrating the attachment of a side covering element on a stud;

FIG. 5 is a perspective view of a support plate for a floor element, in particular of a slab plate, for a stud according to a second embodiment of the invention;

Figure 6 is a sectional diagram, similar to that of Figure 3, to illustrate the attachment of a side trim element on the slab plate of a stud;

Figure 7 is a perspective view of a pad according to a third embodiment of the invention;

Figure 8 is a perspective view of a pad according to a fourth embodiment of the invention;

Figures 9 and 10 respectively represent two embodiments of a lateral covering support, which is an accessory designed to be removably attached to a flange of the stud.

In FIG. 1 is shown a terrace installation on studs 2, comprising floor elements 4 supported by studs 6. In the example, the terrace is bordered by a corner wall M. Within the meaning of this document, the expression “terrace” implies an exterior structure and also includes roof terraces. In other words, raised floor systems, or raised floors, intended for the interior of buildings are not concerned with the invention.

Also, in the example, the floor elements 4 are rectangular tiles. Obviously, any other type of element could be used, and in particular gratings, grates, artificial turf plates, etc. The studs 6 used to directly support the floor elements 4 are called "terrace studs".

In a variant not shown, the studs 6 support joists on which boards are fixed, for example of wood or of composite material. We then speak of studs for joists. However, a stud for a joist remains a patio stud.

A pad 6 of the installation 2 is shown in more detail in Figures 2 and 4, the other pads being identical. Each stud 6 defines an axis Z6, which is vertical when the stud is placed upright on a flat surface, such as a concrete slab for example. Also, the directions "up" and "down" must be interpreted in this configuration, that is to say in a configuration of normal use of the pad.

As visible in FIG. 4, the stud 6 comprises, from bottom to top, a flange 8 for connection to the ground, a nut 10, a threaded head 12 and a support plate 14 for a floor element 4. Here, the plate 14 is described as a "slab plate" because it is designed to support slabs.

The constituent parts of the stud 6 are for example made of plastic, in particular polypropylene, according to a manufacturing technique of the injection molding type.

Here, the flange 8 and the nut 10 are advantageously in one piece. Obviously, the nut 10 could also be manufactured independently of the flange 8. The flange 8 constitutes the part of the stud 6 which is intended to be in direct contact with the ground.

The threaded head 12 is designed to be screwed inside the nut 10, to allow height adjustment. This height adjustment is however optional for the implementation of the invention. The slab plate 14 is positioned in abutment above the threaded head.

Preferably, the threaded head 12 comprises gripping members 12a, which here take the form of radial protrusions, oriented towards the outside, and which allow an operator to pivot the head 12 around the axis Z6, so as to increase or decrease the height of pad 6 (measured along axis Z6). Specifically, the threaded head 12 comprises four pairs of radial protrusions 12a, distributed evenly over the periphery of the head 12.

The threaded head 12 also includes a threaded sleeve 12b, designed to be screwed inside the nut 10.

Advantageously, the slab plate 14 is in two parts 14a and 14b, which are superimposed. However, the two parts 14a and 14b could, as a variant, be replaced by a single piece.

Here, the part 14a is arranged below the part 14b. The part 14b comprises, on its upper surface, separating members 15b, which project radially upward relative to the upper surface of the plate 14b, so that they form partitions making it possible to assist in positioning the slabs above the slab plate 14. Typically, the separation members 15b are arranged in a cross (Greek cross). There are eight in the example, but four of them are actually optional.

The separation members 15b are advantageously each removable or breakable. The members 15b make it possible to divide the surface of the slab plate 14 into four portions, respectively to receive four corners of (four) slabs. Consequently, and in a manner known per se, each slab of the terrace rests on four studs 6, which are positioned at the four corners of the slab.

In the embodiment of Figures 1 to 4, the flange 8 comprises glue traps 16 for fixing an element 18 covering a riser of the terrace. As its name suggests, the element 18 is intended to be positioned vertically on an edge of the terrace to hide the space below the floor elements 4. The main function of these trim elements 18 is therefore aesthetic.

For understanding, a covering element 18 is shown schematically in center lines in FIG. 2.

The covering elements 18 are most often of the same nature as the floor elements 4, which makes it possible to obtain a certain uniformity, and therefore a better aesthetic rendering.

As can be seen in FIG. 3, the glue traps 16 are shaped so that, when the covering element 18 is positioned in contact with the glue traps 16 and the glue traps 16 are filled, at least partially, with glue, the glue, on solidifying, forms fastening members 20 which are glued, on the one hand, to the covering element 18 and mechanically anchored, on the other hand, inside the glue traps 16 , which therefore makes it possible to fix the covering element 18 against the flange 8.

In Figure 3, the glue is shown schematically by a cross filling.

In practice, a strip of glue is affixed to the rear face of the covering element 18 and the covering element 18 is positioned against the glue traps 16. The glue is then removed, by contact pressure, inside the glue traps 16. In fact, the glue used is a liquid or pasty glue, which naturally penetrates inside the glue traps 16 when the covering element 18 is placed against the parts 16.

Advantageously, the glue traps 16 each comprise a bottom wall for retaining the glue, and therefore preventing the glue from escaping from the glue traps 16 under the effect of gravity.

Also, the glue traps 16 each comprise, on the side opposite to the bottom wall, that is to say in the upper part, an opening through which the glue applied to the covering element 18 can flow by gravity. These openings facilitate the filling of the glue traps 16.

Preferably, the glue traps 16 are T-shaped, that is to say that they define a receiving cavity for T-shaped glue. The fixing members 20 formed by the curing of the glue are also T-shaped. This complementary shape means that the fixing members 20, made of hardened glue, are mechanically anchored inside the glue traps 16.

In the embodiment of the figures, the glue traps 16 are organized in a row, that is to say that the glue traps 16 are aligned along an axis X16 which is horizontal when the stud 6 is placed at the place on a flat surface, such as a concrete slab for example.

In the example, the flange 8 comprises at least two rows of glue traps 16, which extend in non-parallel directions X16 and Y16, for example perpendicular. These two rows of glue traps 16 make it possible to assemble two covering elements 18 in a corner, and therefore to dress a corner of the terrace. However, for terrace studs arranged on the edges, and not in the corners, we will actually use only one of the two rows of glue traps 16.

In a variant not shown, glue traps 16 are provided around the entire periphery of the device, that is to say of the flange 8.

According to another variant, the flange 8 may comprise two rows of glue traps which do not form a right angle, but for example an angle less than or greater than 90 °. Thanks to this feature, you can dress all types of corners, including terraces whose angles are not all right.

Figure 3 is a schematic section in a plane parallel to the axes X16 and Y16.

In practice, each covering element 18 is kept fixed between two pieces of at least one stud 6, respectively between the flange 8 for connection to the ground and the support plate 14 of the stud. In the example, each covering element 18 is fixed to two consecutive studs 6.

In the embodiment of FIGS. 1 to 4, a metal angle (not shown) is used, in a manner known per se, to fix the covering element 18 against the support plate 14. The angle is screwed onto the plate support 14 and maintains the covering element 18 in a vertical position thanks to its L shape.

According to another embodiment, shown in Figures 5 and 6, the support plate 14 also includes glue traps 16. As for the flange 8, these glue traps 16 are shaped so that, when the element covering 18 is positioned in contact with the glue traps 16 and that the glue traps 16 are filled with glue, the glue, on solidifying, forms fastening members 20 which are glued, on the one hand, to the element d covering 18 and mechanically anchored, on the other hand, inside the glue traps 16, which therefore makes it possible to fix the covering element 18 against the support plate 14.

In Figure 6, the glue is shown schematically by a cross filling.

Here, the glue traps 16 are also T-shaped.

Also, the glue traps 16 are organized in a row, that is to say that the glue traps 16 are aligned along an axis X16 which is horizontal when the stud 6 is placed upright on a flat surface, such than a concrete slab for example.

In the example, the support plate 14 comprises two rows of glue traps 16, which extend in non-parallel directions X16 and Y16, for example perpendicular. These two rows of glue traps 16 make it possible to assemble two covering elements 18 in a corner, and therefore to dress a corner of the terrace. However, for terrace studs arranged on the edges, and not in the corners, we will actually use only one of the two rows of glue traps 16.

In a variant not shown, glue traps 16 are provided around the entire periphery of the device, that is to say of the support plate 14.

According to another variant, the support plate 14 may comprise two rows of glue traps which do not form a right angle, but for example an angle less than or greater than 90 °. Thanks to this feature, you can dress all types of corners, including terraces whose angles are not all right.

Figure 6 is a schematic section in a plane parallel to the axes X16 and Y16.

In FIG. 7 is shown a slight variant of the embodiment of FIGS. 1 to 4. In the following, only the differences compared to the previous embodiments are mentioned for the sake of brevity. Also, the same reference numerals are used to reference elements common to two embodiments.

In this variant, the flange 8 of the stud 6 further comprises a tongue 22 forming with the glue traps 16 a rail for positioning the covering element

18. This tongue 22 allows here to fix the covering element 18 to the flange 8 without the need to use glue: the covering element 18 is wedged between the glue traps 16 and the tongue 22.

Advantageously, the tongue 22 is breakable. Insofar as this tab 22 is visible from the outside, it can be sectioned, by hand or with a tool, for applications where the studs 6 must be completely invisible from the outside. In this case, the covering elements 18 will be fixed by gluing.

Preferably, the mechanical connection between the tongue 22 and the rest of the flange 8 comprises a zone of weakness, which allows an easy and quick section by hand.

According to another embodiment, shown in Figures 8 and 9, the glue traps 16 are part of a lateral covering support 24, which is an accessory designed to be removably attached to the flange 8 of the stud 6 In particular, the flange 8 comprises several vertical sides 26 and the lateral covering support 24 comprises a slot 28. The slot 28 has a width comparable to that of the sides 26, or even less, so that the lateral covering support 24 can be fixed to the flange 8 simply by inserting, optionally by force, one of the sides 26 inside the slot 28. Thus, the mounting of the covering support 24 does not require any particular tool.

In the embodiment of FIGS. 8 and 9, the lateral covering support 24 also includes a tongue 22, comparable to that of the stud shown in FIG.

7. This tongue 22 can be used to keep the covering element 18 without glue, especially if its visibility is not obstructing from an aesthetic point of view. As for the previous embodiment, the tongue 22 is preferably breakable.

In this regard, FIG. 10 shows an example of a lateral covering support 24 in which the tongue 22 has been cut. In this example, the lateral covering support 24 is completely invisible once the covering elements 18 have been installed, which provides an aesthetic appearance and a quality finish.

In summary, the glue traps 16 belong to at least one device from the flange 8, the support plate 14 and the lateral covering support 24 designed to be removably attached to the flange 8 of the stud 6. Obviously, the different embodiments can be combined, so that glue traps 16 can be found in the upper part and / or in the lower part of the stud 6, respectively at the level of the support plate 14 and / or of the flange 8.
