ASSISTANCE PLOT FOR LAYING FLOOR ELEMENTS SUCH AS SLABS, RAISED FLOOR SYSTEM INCLUDING SAME, AND METHOD OF IMPLEMENTING SAME

The present invention relates to the field of raised floors of the paving type, and relates in particular to a support pad for the installation of floor elements of the slab type, on a raised floor system comprising it and on a method of setting corresponding work.

The term "floor element" means any element intended to form a floor surface, such as a concrete slab.

It is known to form a raised floor using a plurality of modular slabs arranged on a plurality of support means. In particular, each square-shaped slab is supported at each of its four corners by a specific support means which also allows the slab to be adjusted in height. The adjustable support means thus make it possible to ensure good flatness of the immediately adjacent slabs and more generally of all of the slabs forming the floor.

Each of these support means generally comprises a lower sole applied to the ground and a stud of adjustable length between the lower sole applied to the ground and an upper head bearing against the underside of the slabs. Each slab angle rests on a block common to different neighboring slabs.

With such studs currently available and offering a bearing surface only at the angles of the slabs, the method of laying on the stud requires the use of slabs of significantly higher mechanical strength, and therefore of greater thickness, than that of the slabs on uniformly distributed supports (sand, mortar, etc.).

The object of the present invention is to provide a fitting aid pad allowing the use of tiles having a mechanical resistance significantly lower than that currently required to comply with the regulations in force concerning floor coverings formed by tiles laid on studs.

Furthermore, it should be noted that the known support pads are of a different nature from the nature of the tiles and therefore of the raised floor. Indeed, these studs are most often made of plastic or metallic material, for example cast aluminum or galvanized steel, while the slabs are made of concrete. However, particularly with regard to fire safety standards, it could be advantageous to avoid the use of such materials because metallic materials lose their mechanical characteristics at temperatures much lower than concrete. These metallic materials are moreover capable of generating gaseous fumes from a certain temperature level.

Another objective of the present invention is therefore to propose a fitting aid consisting of a material offering better resistance to temperature or fire resistance.

The present invention thus aims to solve the drawbacks of the prior art, by proposing a support pad for laying floor elements, such as slabs, intended to support said floor elements relative to the ground. during their installation and to ensure the flatness of a floor formed by said floor elements, which stud comprises:

- A stabilizing base having a lower surface called the seating surface intended to be applied to the ground, and an opposite upper surface known as the receiving surface, a female receiving part opening onto the receiving surface; and

- a height adjustable pin assembly positioned above the stabilizing base, the pin assembly comprising a male part intended to be received in the female receiving part, extending along a vertical axis substantially perpendicular to the seat surface, such so that the male part is movable relative to the female part in the vertical direction with an upper surface of the male part substantially parallel to the seat surface, the fitting aid pad being characterized in that the Pawn assembly further comprises a temporary part positioned in the vertical alignment of the male part, the temporary part being able to disappear after the laying of the floor elements, so that, as long as the temporary part has not not erased, the male part takes up the forces exerted by the support of said floor elements.

Of preferably the party temporary is a party in biodegradable material, of preference a soluble membrane capable of dissolving in Water. In a such case the temporary part is suitable for disappear, and

will disappear after being brought into contact with water, either by the action of a person pouring water on the floor elements, or naturally as for example by rain water.

According to the present invention, it would be entirely possible to envisage temporary parts of more complex structure, the erasure of which would in fact be a reduction in the height of the temporary part after a certain time, such as for example temporary parts comprising mechanical systems. can be actuated or not remotely (cylinder type, holding in the maximum height position by a movable stop whose retraction allows passage to a position of smaller height, etc.).

It is understood that the temporary part according to the present invention includes such more complex systems, although a temporary part made of biodegradable material is particularly advantageous because of its simplicity of structure and use.

Advantageously, the temporary part is arranged on the male part.

According to a first embodiment of the invention, the female receiving part is formed by a cylindrical recess opening substantially at the center of the receiving surface of the base, the male part comprising a threaded hollow cylindrical barrel engaged in the recess, and a screw-nut system having a screw whose threaded rod is capable of being received with thread in the barrel

and positioned from so that the head of the screw shape the area superior of the male part, sure which East willing the part temporary, and a nut in taken with the

screw thread rod below the screw head.

According to a second embodiment of the invention, the female receiving part is formed by an internally threaded annular recess opening out substantially at the center of the receiving surface of the base, the male part comprising an externally threaded cylinder engaged with the internal wall. threaded from the recess, the number of threads of the cylinder being greater than the number of threads of the recess and the temporary part being arranged on the end face of said cylinder.

The temporary part can alternatively be placed under the male part. This positioning prevents the temporary part from being deformed by the pressure exerted by a floor element, in particular when laying heavy slabs, and therefore avoids the risk of this part being punched.

According to a third embodiment of the invention, the female receiving part is formed by a non-through annular recess opening substantially at the center of the receiving surface of the base, the male part comprising a screw-nut system having a dimensioned external nut. and configured to be received in the recess, and an inner screw cooperating with the nut and positioned so that the head of the screw forms the upper surface of the male part, the temporary part being disposed on said upper surface of the part male or between the outer nut and the bottom of the female receiving part.

The stud may further comprise a reinforcing part formed on the base, around the female part.

The present invention also relates to a method of implementing a support pad for laying floor elements as defined above, characterized in that the method comprises:

the laying of the stud on the ground at a given position, in particular at a position intended to be opposite each corner region of the floor element, with the seat surface of the base in contact with the ground;

- adjusting the height of the stud relative to the ground by means of the pin assembly;

- the production of a predetermined number of load-bearing elements, in particular at positions intended to be below the corner regions of the floor element; and

the laying of at least one floor element on the stud, the floor element resting both on the upper surface of the stud assembly and on the load-bearing elements, so that after the temporary part s 'is deleted, a space is created between the floor element and the stud, the floor element then resting only on the load-bearing elements and the stud no longer taking up the forces exerted by the support of the floor element.

According to a particular embodiment, the step of producing a predetermined number of load-bearing elements comprises pouring at least one mortar pad on the receiving surface of the base, preferably four mortar pads placed at the four corners of the base in the case of a square base, so that the or each mortar pad extends between the receiving surface of the base and the plane to which the upper surface of the peg assembly belongs.

According to another particular embodiment, the step of making a predetermined number of load-bearing elements comprises making a cylindrical hole in the ground, in particular in a stable incompressible ground, inserting a retaining structure deformable, in the form of a hollow cylinder, in the hole, so that the deformable retaining structure protrudes above the ground to a height at least equal to the height of the adjusted stud, and the pouring of concrete in the deformable retaining structure so as to fill it.

The use of deformable retaining structures inserted into the ground, rather than load-bearing elements produced on the base of the fitting aid pad, makes it possible to dispense with the steps for laying frost-free. Indeed, with such load-bearing elements, it suffices to have a stable incompressible soil.

In addition, such deformable retaining structures allow the concrete to be poured easily and cleanly.

Preferably, the method according to the present invention can also comprise the additional step consisting in placing at the top of at least certain support elements, preferably all the support elements, a capillary rupture means, such as a film, a membrane, a strip, made of waterproof material. This makes it possible to avoid capillary risings liable to lead to degradation of the floor elements.

The present invention also relates to a floor system of the paving type or heated floor comprising a plurality of mounting aid pads as defined above, and a plurality of floor elements of the slab or plate type, the installation aid pads being implemented according to the method as defined above, so that the slabs / plates are joined to each other in a horizontal plane and that, when laying the slabs / plates , the slabs / plates rest on the stud sets of the studs and on the load-bearing elements, and after the temporary parts have been erased, the slabs / plates rest only on the load-bearing elements.

Thanks to the positioning aid pads and the load-bearing elements of the present invention, large-sized floor elements can be used. In particular, the greater the number of mounting aid pads and carrier elements used, the greater the dimension of the floor elements.

To better illustrate the object of the present invention, there will be described below, by way of illustration and not limitation, preferred embodiments, with reference to the accompanying drawings.

If one refers to Figures IA to 3B, it can be seen that there is shown a fitting aid pad 1, 1 ′, Y ′ of floor elements 2 according to the present invention, which is intended to support floor elements 2 relative to the ground during their installation.

The positioning aid stud 1, 1 ′, Y ′ according to the present invention comprises a stabilizing base 3, 3 ′, intended to be placed on the ground, and a pin assembly 4,

4 ', Y' intended to allow the height of the stud to be adjusted

1, 1 ', Y' and take up the forces exerted by the support of the floor elements 2 (shown in Figures 4 to

7) during their installation. The stabilizing base 3, 3 ', 3 comprendο includes a female receiving part 30, 30', 30 intended to receive the pin assembly 4, 4 ', 4 and a reinforcing part 31, 31', 31 intended to reinforce the stud 1, 1 ',

1. The pin assembly 4, 4 ′, 4 comprises a male part 40,

40 ′, 40 dimensioned and configured to cooperate with the female part 30, 30 ′, 30, and a temporary part 41,

41 ', 41 intended to disappear after the laying of the floor elements 2.

The base 3, 3 ', 3 is preferably made of concrete.

The base 3, 3 ', 3 has a polygonal shape, preferably square. In the preferred embodiments shown in the Figures, the base 3, 3 ', 3 is in the form of a straight block having four rectangular lateral faces and two square faces 3a, 3b. The side faces may be slightly inclined towards the inside of the base 3, 3 ′, 3, so that the surface of the lower square face 3a is slightly greater than the surface of the upper square face 3b. The lower square face 3a is called the seating surface and is intended to be applied to the ground. The upper square face 3b is called the receiving surface.

A female receiving part 30, 30 ', 30 in the form of a recess is formed in the center of the base 3, 3', 3. This female part 30, 30 ', 30 opens at least on the upper face 3b of the base 3, 3 ', 3, in particular also at the height of the reinforcement part 31, 31', 31, and extends perpendicular to the seat surface 3a.

If we refer more specifically to

Figures IA to IC, it can be seen that there is shown a fitting aid pad 1 according to a first embodiment of the invention.

The part female 3 0 is trained by a obviously cylindrical which spans all the height of base 3, that is to say that he also leads to the area seat 3a. This part female 30 receives and support

the pawn set 4.

The pin assembly 4 comprises a male part 40 and a temporary part 41 disposed on the male part 40.

The male part 40 comprises a hollow cylindrical barrel 40a threaded engaged in the female part 30, and a screw-nut system. The threaded hollow cylindrical barrel 40a is received in the recess 30 in the center of the base 3, so that it extends perpendicular to the seat surface 3a.

The diameter of the barrel 40a is substantially equal to that of the recess 30 in the base 3, and the barrel 40a is made integral with the base 3 by any suitable means. The length of the barrel 40a is greater than the length of the recess 30, so that the barrel 40a protrudes above the receiving surface 3b of the base 3.

The screw-nut system is partly received in the barrel 40a and protrudes above it.

The screw-nut system comprises a screw 40b and a nut 40c. The screw 40b is formed by a threaded rod carrying a flat head at one of its ends. The threaded rod has a diameter substantially equal to the internal diameter of the barrel 40a, so that the external thread of the rod and the internal thread of the barrel 40a are engaged with each other. Thus, by rotation of the screw 40b relative to the barrel 40a, the threaded rod is able to perform a translational and rotational movement relative to the barrel 40a. The flat head is disc-shaped and is located at the upper end of the threaded rod. The flat head has circular upper and lower faces extending in planes substantially parallel to the seat surface 3a of the base 3. The upper face constitutes the so-called bearing surface of the pad 1.

The displacement of the screw 40b relative to the barrel 40a, and therefore the height of the stud 1, is adjustable by means of the nut 40c.

The nut 40c is integral with the threaded rod, under the flat head. Thus, a simple rotation of the nut 40c in one direction or the other makes it possible to vertically move the male part 40 and therefore to increase or decrease the height of the stud 1.

The barrel 40a and the screw-nut system 40b, 40c are preferably made of a metallic or plastic material.

The temporary part 41 is mounted at the top of the stud 1. In particular, the temporary part 41 rests on the bearing surface of the male part 40. The temporary part 41 is preferably made up of a seal or a material membrane biodegradable. The seal or the membrane is in the form of a disc whose diameter is equal to the diameter of said bearing surface of the male part 40. The material of the temporary part 41 is preferably a material soluble in l 'water.

For example, the biodegradable material will be starch, or a water-soluble polymer.

The pad 1 finally comprises reinforcing elements 31, made of concrete, and formed integrally with the base 3 of concrete.

In the embodiment shown in the

Figures IA to IC, the stud 1 comprises four reinforcing elements 31 in the form of radial ribs positioned on the receiving surface 3b of the base 3. Each of the reinforcing elements 31 extends radially from the center of the base 3, around the female part 30, and up to a region close to the edge of the base 3. Each reinforcing element 31 forms a right angle with the reinforcing elements 31 adjacent thereto. Thus, the reinforcing elements 31 define a cross which cuts the base 3 into four zones of the same dimensions. Each reinforcing element 31 has a substantially rectangular trapezoidal shape in longitudinal section. The height of each reinforcing element 31 is substantially equal to the height of the barrel 40a.

For example, for a pad 1 having a base 3 of square section whose sides have a length of 250 mm, the height of the base 3 is 35 mm, the width of the reinforcing elements 31 is 25 mm, the distance between the outer edge of the reinforcing elements 31 and the edge of the base 3 is 20 mm, the barrel 40a protrudes above the receiving surface 3b of the base 3 over a length of 28 mm, and the temporary part 41 and the flat head of the screw 40b have a diameter of 40 mm.

A stud 1 with such dimensions allows a laying of floor elements 2 at least about 8 cm above the ground on which the stud 1 is placed.

The installation aid stud 1 as described above makes it possible to support floor elements 2 relative to the ground during their installation and to ensure the flatness of a floor formed by these floor elements 2 by the adjustment of the height of the stud 1.

If reference is now made to FIGS. 2A and 2B, it can be seen that there is shown a fitting aid pad 1 'according to a second embodiment of the invention.

As in the first embodiment, the female receiving part 30 'is formed by a through recess made substantially in the center of the receiving surface 3b of the base 3'. Unlike the first embodiment, the recess 30 'is internally threaded.

The pin assembly 4 'includes a male part 40' in engagement with the female part 30 'and a temporary part 41'. The temporary part 41 ', similar to that described in the first embodiment, is shown arranged above the male part 40'.

The male part 40 ′ is of simple structure and comprises a single piece, namely a cylinder externally threaded at least on its lower portion. The external threads of the cylinder 40 'come into engagement with the internal threaded wall of the annular recess 30'. The number of threads of the cylinder 40 'is greater than the number of threads of the recess 30', so that the length of the cylinder 40 'is greater than that of the recess 30'. At least one vertical notch 40'c, in the example shown four notches 40'c, is provided on the lateral face of the male part 40 ', in its upper unthreaded part. The or each notch 40'c allows the user to introduce a tool, such as a flat iron or a screwdriver tip, to allow him to rotate the male part 40 'and therefore to move the assembly in height. pawn 4 '.

In this second embodiment, the reinforcing part 31 ′ is in the form of a halo formed around the female part 30 ′ and protruding above the receiving surface 3b of the base 3 ′.

As can best be seen in Figure 2B, the temporary part 41 'has in its center a small cylindrical projection 41'a extending downward and received in a corresponding hole 40'a provided on the upper face of the part male 40 ', so that the temporary part 41' is held in position on the male part 40 'during use.

If we also refer to Figure 2C, we can see that the projection 41'a on the temporary part 41 / hole 40'a in the male part 40 'can be replaced by a cooperation of four projections 40'b s 'extending upwards from the upper face of the male part 40' and four slots 41'b provided in the temporary part 41 ', dimensioned and positioned so that each projection 40'b extends through a slot 41 'b corresponding when the temporary part 41' is applied to the male part 40 '.

For example, for a stud 1 ′ having a base 3 ′ of square section whose sides have a length of 500 mm, the height of the base 3 ′ is 60 mm in the part not including the reinforcement part 31 ', and 100 mm between the seat surface 3a and the upper face of the reinforcement part 31', the width of the reinforcement part 31 'is 80 mm, the distance between the outer edge of the reinforcement part 31 'and the edge of the base 3' is 90 mm, the temporary part 41 'and the cylinder 40' of the male part and the recess 30 'of the female part have a diameter of about 160 mm.

If we now refer to FIGS. 3A and 3B, it can be seen that there is shown a fitting aid pad Y 'according to a third embodiment of the invention.

As in the second embodiment, the female receiving part 30 is formed by an annular recess produced substantially in the center of the receiving surface 3b of the base 3 and in particular defined by the ends of four reinforcing parts 31 which are part of the base 3. Unlike the second embodiment, the recess 30 extends only over part of the height of the base 3 and it is not internally threaded. A through hole 30a extends between the bottom of the recess 30 and the seat surface 3a.

The pin assembly 4 comprises a male part 40 in engagement with the female part 30 and a temporary part 41.

The part temporary 41, similar s i that described in the first mode of achievement, is of preferably willing below of the male part 4 0, to know between the bottom of the female part 30 and the face

lower part of the male part 40.

The male part 40 comprises a screw-nut system having an external nut 40a sized and configured to be received and fixed in the recess 30, and an internal screw 40b cooperating with the nut 40a and positioned so that the head of the screw 40b forms the upper surface of the male part 40.

In this third embodiment, the reinforcing part 31 comprises four radial reinforcing elements at 90 degrees from each other, here each defining a part of the receiving surface 3b and thus delimiting the female part 30.

Three embodiments have been shown for the male and female parts. However, other embodiments in which a male part is dimensioned and configured to be received and supported in a female part, so that the male part is movable vertically relative to the female part, can be envisaged.

Likewise, three embodiments have been shown for the reinforcing part of the base, however other embodiments can be envisaged and adapted in the case of bases not having a square cross section.

If we now refer to Figures 4 to 7, we can see that the pad 1, 1 ', Y' allows the installation of floor elements 2 such as slabs, especially for the realization of a terrace.

As can be seen, the production of a slab floor 2 comprises at least four steps, namely a first step of laying the mounting aid pads 1, 1 ', Y', a second step of adjusting the height

studs 1 1 '- ^L r - ^L r -i ^{Z /} 1 _r a third stage of achievements elements carriers 6 and a fourth step of pose of slabs 2. The stud 1 1 ' U r 1 owns a pedestal 3, 3 ', 3 in concrete such so that it is appropriate for a

use on turf, gravel and other non-hard soil surfaces. Thus, the step of fitting the pad 1, 1 ′, Y ′ consists in applying the seat surface 3a of the base 3, 3 ′, 3 to a desired floor surface.

Indeed, the implementation of the pad 1, 1 ′, Y ′ according to the present invention does not necessarily imply disbursing the ground, laying a bed of gravel, compacting it then pouring a concrete slab.

For the production of a square slab floor 2, the installation of the pads 1, 1 ′, Y ′ also includes their installation in defined positions. As shown in Figures 4 and 5, the positioning of the pads 1, 1 ', Y' can be achieved as follows: a square paving is made, each square of the paving having an area equal to the surface of the slabs 2 to be supported , and the positioning aid pads 1, 1 ', Y' are placed in the paving so that the distance between the center of two neighboring pads 1, 1 ', Y' located along adjacent squares in the paving corresponding to the width of a slab 2. Depending on the type of soil on which the studs 1, 1 ', Y' are laid, the stud 1, 1 ', Y' is either simply laid, or keyed or sealed to the ground .

Once the studs 1, 1 ', Y' positioned and if necessary fixed on the ground, in the appropriate positions, the height of each stud 1, 1 ', Y' is adjusted to compensate for any irregularities in the ground.

Conventional tools are used for the

setting the height, such as a line, a ruler, etc. , to modify the height of a stud 1, 1 ', 1 by displacement of the male part 40, 40 ', 40 compared to the female part 30, 30 ', 30. A times the aid pads pose 1, 1 , _η // r - ¹ -

adjusted, a given number of load-bearing elements 6 are produced.

According to a first embodiment of the method for implementing the positioning aid pads 1, 1 ′, Y ′, the production of the load-bearing elements 6 comprises the pouring of mortar onto the receiving surface 3b of the base 3, 3 ', 3, preferably four blocks of mortar 6 in the four zones delimited by the reinforcement elements 31, 31, or in the four corner regions of the block in the case of reinforcement parts 31' in the shape of a halo, so as to form four bearing mortar studs 6, the upper face of which, after the mortar has collapsed, at the same height as the upper face of the peg assembly 4, 4 ′, Y ′ of the stud 1, 1 ′, 1.

According to a second embodiment of the method for implementing the positioning aid pads 1, 1 ′, Y ′, as shown in FIG. 7, the production of the carrying elements 6 includes the production of a cylindrical hole in the ground, preferably in a stable incompressible soil, the insertion of a deformable retaining structure 60, in the form of a hollow cylinder, into the hole, so that the deformable retaining structure 60 protrudes above the ground to a height at least equal to the height of the stud 1, 1 ′, Y ′ set, and the pouring of concrete into the deformable retaining structure 60 so as to fill it.

The holes in the ground can be made using an auger or any suitable tool.

The holes are made in positions allowing optimal support for the floor elements 2, in particular in positions intended to come opposite the corner regions of the floor elements 2 placed.

The deformable retaining structure 60 is made in particular of plastic and makes it possible to contain and retain the concrete poured into it, and to collapse at the same time as the subsidence of the concrete that it contains.

After the carrying elements 6 have been produced, it is advantageous to place capillary breaking means, also called antihumidity, at the top of each of them, for example in the form of pieces 7 of film made of waterproof material, such as for example plastics. These pieces of film 7 will prevent capillary rise which otherwise could lead, for example, to the appearance of water spots on the floor elements 2.

Finally, the slabs 2 are placed on the pads 1, 1 ′, 1, so that each of the corners or corner regions of the slab 2 rests on the peg assembly 4, 4 ′, 4 of the assistance pads. laying 1, 1 ', Y' positioned below the slab 2. The installation of the slabs 2 allows the load-bearing elements 6 which were produced in the previous step to harden to the desired height.

With such an arrangement, each fitting aid pad 1, 1 ′, Y ′ supports the corner or the corner region of several adjacent tiles 2 at the time of their installation and takes up the forces exerted by the support of these tiles 2.

After some time, the temporary part 41, 41 ′, 41 disappears, in particular by dissolution in water. A space is then created between the lower face of each slab 2 and the upper face of the pin assembly 4, 4 ', 4 of each stud 1, 1', Y '. The weight of the slabs 2 is then taken up by the load-bearing elements 6 which support the corner regions of each slab 2. The peg assembly 4, 4 ', 4' 'of the pads 1, 1', Y 'then becomes non-load-bearing.

As can be seen in FIG. 6, the positioning aid pads 1, 1 ′, Y ′ can also be used for the installation of floor plates 2, such as heated floor plates. The installation process comprises the same steps as for the installation of tiles 2, only the positioning of the installation assistance pads 1, 1 ′, Y ′ being adapted to the dimensions of the plate 2. In fact, in this case, the studs 1, 1 ', Y' are positioned so that each plate 2 is supported by a stud 1, 1 ', Y' at each of its corners and by a central stud 1, 1 ', in the center of this one.

The mounting aid pads 1, 1 ', 1 and the floor elements 2 supported by these pads 1, 1', 1 form a floor system. In such a floor system, the studs 1, 1 ', 1 comprise a concrete base 3, 3', so that the studs 1, 1 ', 1 no longer have to be placed on a slab made of concrete, allowing faster construction of the floor system. In addition, the forces due to the support of the floor elements 2 are distributed and taken up by load-bearing mortar / concrete elements 6 positioned below the corner regions and possibly central of the floor elements 2, and not only at the level angles. Thus, the floor system can comprise floor elements 2 of less thickness compared to a support on studs positioned only at the angles of the floor elements 2.

It is emphasized here that the presence of a recess or hole also opening into the seat surface 3b of the base 3 makes it possible to prevent water from remaining trapped in a stud, which could pose difficulties in the case where it would freeze.
