Definitions
- the present invention relates to floor slabs for the circulation of people, and floors comprising such slabs.
- Fire safety regulations particularly those applicable to buildings intended for public use, impose strict requirements.
- fire reaction and fire resistance both coded at national and European level.
- the reaction to fire is the representation of a material as a fire feed (combustibility, flammability), defined by the M classification in France and the Euroclass Ax sx dx classification in Europe.
- Fire resistance is the time during which the building element plays its role of limiting the propagation.
- the present invention aims to provide a slab that resists fire well.
- fire resistance indicates the time during which a building element (wall, floor, ceiling, door, etc.) during a fire retains its physical and mechanical properties.
- This material is classified in three categories:
- fire-resistant SF the building element retains, for the time indicated, its lift and self-lift;
- flamethrower PF the element is fire-resistant and avoids, for the time indicated, the propagation of the flue gas and smoke on the undisturbed side;
- the element is flameproof and avoids, during the indicated time, the propagation of the heat of the not affected side.
- the thermal insulation corresponds to a maximum of 180 ° C at a specific point, and 140 ° C over the entire surface (a door for example).
- SF 2h means fire stable for 2 hours.
- Intumescent materials are known to swell under the action of heat to form an insulative microporous foam called meringue. It protects the supports against fire, limits the propagation of fire and delays the rise of the temperature of materials.
- the present invention aims to overcome this disadvantage.
- the subject of the invention is a slab comprising:
- an upper circulation plate adapted to form a floor element allowing the circulation of persons, the upper plate being adapted to allow the light to pass;
- an intumescent layer adapted to increase volume from a predetermined temperature, disposed between the upper and lower plates, the intumescent layer being adapted to let the light;
- expansion space between the upper and lower plates, the expansion space being adapted to allow expansion of the intumescent layer.
- the lower plate comprises a glass sub-layer and a marble underlay fixed to each other;
- the glass underlayer and the marble underlay each have a thickness of between 4 and 10 mm;
- the expansion space comprises a first expansion zone between the intumescent layer and the upper plate, and a second expansion zone between the intumescent layer and the lower plate;
- each expansion zone has a thickness of at least 3 mm;
- the upper plate comprises at least three glass sub-layers;
- the intumescent layer is made of glass and has a thickness of between 10 and 50 mm;
- the slab has a total thickness of between 50 and 100 mm.
- the invention also relates to a floor comprising a support frame and a plurality of slabs as previously described fixed on the support frame.
- the support frame comprises a mesh of metal sections and a thermal insulation device surrounding the profiles;
- the thermal insulation device comprises at least one insulating block made of fibrosilicate
- the thermal insulation device comprises at least one element selected from an intumescent strip and an intumescent paint.
- FIG. 1 is a transverse vertical sectional view of a portion of a slab according to the invention.
- Figure 2 is a top view of the slab of Figure 1;
- FIG. 3 is a transverse vertical sectional view of a portion of a floor according to the invention.
- Figure 1 illustrates a portion of a slab 10 according to the invention.
- the X axis is the longitudinal axis
- the Y axis is the transverse axis
- the Z axis is the vertical axis.
- the slab 10 comprises an upper plate 12, a lower plate 14, an intermediate layer 16 disposed between the upper and lower plates 12 and 14, and an expansion space 18 between the upper and lower plates 12 and 14.
- the upper plate 12 is a circulation plate adapted to form a floor element allowing the movement of people.
- the upper plate 12 can be adapted to withstand a load of at least 500 kg / m 2 , the maximum load depending on the dimensions of the slab 10.
- the upper plate 12 is adapted to allow the light to pass, that is to say that it can be translucent or transparent.
- the upper plate 12 comprises at least three sub-layers 20 of glass.
- the number of underlayments is determined by the standards for floor slabs.
- the composition of the upper plate 12 can be very variable, ranging for example from a simple laminate of 6 + 6 mm to a tri-laminated as imposed in France.
- the upper plate 12 is a tri-laminated plate and comprises exactly three sublayers 20 stacked on top of each other, including an upper underlayer 20A, an intermediate underlayer 20B and a lower sublayer 20C.
- Each underlayer 20A, 20B, 20C may be tempered extra white glass.
- the upper sub-layer 20A may have a thickness along the vertical axis Z of between 5 and 7 mm, for example substantially equal to 6 mm.
- the intermediate sublayer 20B and lower 20C may have a thickness of between 7 and 9 mm, for example substantially equal to 8 mm. As described above with respect to the number of underlays of the top plate 12, the thickness of the underlays as well as their treatment (quenching, annealing, etc.) are dictated by the national standards for floor slabs.
- Sub-layers 20A, 20B, 20C may, for example, be fixed to each other by two colorless films 22 of PVB (PolyVinyl of Butyral).
- PVB PolyVinyl of Butyral

- the grooves 26 may have any profile, for example U or W.
- the slab 10 may comprise any decorative pattern. She may also not understand a pattern at all.
- the upper surface 28 of the slab 10 can receive a sanded or etched treatment, etching, screen printing, etc.
- the upper plate 12 may be monolayer or bilayer.
- the lower plate 14 is a translucent plate forming a thermal barrier.
- the lower plate 14 may comprise a first sub-layer 32 of glass and a second sub-layer 34 of marble fixed to each other, in particular by welding-bonding.
- the fixation by welding-bonding has the advantage of not introducing interlayer material such as a PVB film which has a tendency to turn yellow with time and especially which provides a heat input because it is combustible.
- the welding-bonding is a fixing process in which there is a supply of energy in the form of photons which allows a molecular connection between the materials with very little contribution of organic matter.
- the finished product is very resistant to UV, temperature differences, humidity and pollution and ages very well over time.
- the first underlayer 32 is extra-white glass and makes it possible to stiffen the lower plate 14.
- the marble used for the second underlayer 34 is for example Thassos marble.
- the glass sub-layer 32 and the marble sub-layer 34 each have a thickness of between 4 and 10 mm, for example substantially equal to 6 mm.
- the glass underlayer 32 is disposed above the marble underlayer 34.
- the marble underlayer 34 may be disposed above the glass underlayer 32.
- the marble sub-layer 34 may be replaced by a granite sub-layer.
- the granite sub-layer has a thickness of less than 2 mm, for example substantially equal to 1 mm.
- the thickness of the second sub-layer 34 of marble or granite is chosen sufficiently thin so as to ensure a translucent appearance, but not too fine so as to ensure sufficient rigidity and good fire resistance.
- the intermediate layer 16 is an intumescent layer adapted to increase volume from a predetermined temperature.
- the intumescent layer 16 is adapted to allow the light to pass, that is to say that it can be translucent or transparent.
- the intermediate layer 16, hereinafter intumescent layer 16, is made of glass and has a thickness of between 10 and 50 mm, for example substantially equal to 18 mm.
- the glass used for the intumescent layer 16 is a fireproof glass 30 minutes (called "CF l / 2h” according to the French classification), for example the glass marketed under the trademark Pyrostop®.
- the intumescent layer 16 begins to foam and swells.
- the glass used for the intumescent layer 16 may be a higher degree fireproof glass, for example CF 2h, CF 3h, CF 4h or more.
- the expansion space 18 is adapted to allow the expansion of the intumescent layer 16.
- the expansion space 18 includes a first expansion zone 36 between the intumescent layer 16 and the upper plate 12, and a second expansion zone 38 between the intumescent layer 16 and the lower plate 14.
- Each expansion zone 36, 38 has a thickness at least equal to 3 mm, for example substantially equal to 4 mm.

- Each spacer 40 comprises a shim 42 of extra-white glass and a thickness of at least 3 mm, for example substantially equal to 4 mm.
- the shims 42 are fixed respectively on the lower sublayer 20C and the underlayer of glass 32, in particular by bonding.
- Each spacer 40 further comprises a seal 44 transparent or translucent and of thickness substantially equal to 1 mm, disposed between the intumescent layer 16 and the shim 42 respectively.
- the seal 44 is a flexible seal having vibration-absorbing properties, thus sealing the expansion zones 36, 38, particularly against water and dust, but also to take up the loads. operating the slab.
- the spacers 40 have a width L1 between 25 and 50 mm, for example substantially equal to 30 mm.
- the width L1 can be decreased or increased depending on the loads to be resumed and / or the size and shape of the slab 10.
- the edges of these spacers are preferably rounded to avoid creating glass break primers.
- the spacers 40 thus allow not only the expansion of the intumescent layer 16 without the bridle, but also allows to resume the operating costs of the slab.
- the slab 10 thus has a total thickness E of between 50 and 100 mm, in the example described here substantially equal to 65 mm.
- the slab 10 has a square shape of side between 350 and 500 mm, in the example described here substantially equal to 430 mm.
- the slab 10 may have any shape, for example rectangular, triangular, octagonal, etc.

- T irons 54A, 54B are fixed to each other so as to form between them housing 57 each adapted to receive a slab 10.
- the thermal insulation device 56 comprises a hood 58, at least one insulating block 60 and an intumescent strip 62.
- the cover 58 has a U-shape and is made, in the example described here, Aluzinc ® , which ensures a good resistance to corrosion and to have a role of fire retardant.
- the cover 58 has a width L2 between 60 and 80 mm, for example substantially equal to 70 mm.
- a central insulating block 60A is fixed, in particular by gluing, in the bottom of the cover 58 and two lateral insulating blocks 60B are fixed, in particular by gluing, against the inside of the wings 64 of the U-shaped cover 58.
- the adhesive to use for these collages is an adhesive having properties of resistance and reaction to fire and guaranteeing the cold use, for example the glue "LUX-2008-1" provided by Luxinov.
- the side blocks 60B are spaced from the central block 60A so as to be able to insert angles metal 66, in particular Aluzinc ® , used for fixing the thermal insulation device 56 on irons T 54A, 54B.
- cover 58 and the side blocks 60B are screwed onto the brackets 66 which are themselves glued to the wings 68 of the irons T 54A, 54B.
- a glue that can be used for this purpose is the "LUX-2010-MM" glue supplied by Luxinov.
- the intumescent strip 62 is fixed, in particular glued, on the angles 66.
- the intumescent strip 62 is of the Flexilodice type.
- the thermal insulation device 56 of the irons T 54A, 54B may comprise an intumescent paint applied in particular on the outer face of the cover 58.
- the slabs 10 are centered in the housings 57 and arranged on the intumescent strips 62.
- the gap I between each slab is between 8 and 15 mm, for example substantially equal to 9 mm.
- the interval I is chosen according to the section of the iron T used, the loads applied and the desired aesthetic appearance.
- This gap is filled by a molecular sieve 70 also serving as a seal, for example silica powder, to absorb moisture and ensure smoke tightness in case of fire.
- a molecular sieve 70 also serving as a seal, for example silica powder, to absorb moisture and ensure smoke tightness in case of fire.
- a neutral silicone seal and seal 72 covers the molecular sieve and is processed to mimic the groove 26, thereby ensuring the seal between the slabs and the homogeneity of the decorative slab pattern ( Figure 2).
- seal 72 may be replaced by sealed stainless steel metal inserts, LED strips, other materials such as copper, brass wood, etc.
- the invention thus proposes a thin CF lhl / 2 multilayer glass roof slab and a CF lhl / 2 multilayer glass floor which are light and inexpensive.
- the marble / glass plate acts as a heat barrier, the marble accumulates heat and gradually restores it to the intumescent layer, thereby delaying the onset of swelling and thus the cutting action. fire intumescent layer CF l / 2h.
- the marble / glass plate gives the slab an unprecedented aesthetic appearance and contributes to a subdued diffusion of light through the translucent slab.
- the assembly of the various glass elements of the slab by welding-bonding makes it possible not to introduce additional elements and therefore to have monolithic glass elements and a monoblock slab, ready for installation, thus allowing a gain in installation time thanks to easy handling and easy storage, thereby helping to reduce the cost of the floor.
- the thermal insulation device makes it possible to protect the support frame of the floor from the fire and thus contributes to guaranteeing the degree CF lhl / 2 of the floor.
- the glasses used for the different layers of the slab may be arbitrary, for example, glasses with variable opacity, glasses with metallic layers, various special glasses, etc.
- the thickness and the treatment of the various glass layers can be arbitrary (float glasses, colored glasses, tempered glasses, semi-tempered glasses, screen-printed glasses, etc.).
