Definitions

• the present invention relates to a parquet with floating support.
• It relates more particularly to a parquet composed of a set of contiguous parallel slats, which is supported by a set of load distribution plates parallel to each other, laid on the ground by means of a resilient underlay on which they rest. .
• the slats are assembled edge-to-edge with each other by a tongue and groove interlocking system, possibly with bonding of the tongue in the groove.
• a tongue and groove interlocking system possibly with bonding of the tongue in the groove.
• parquet there are two main categories of parquet thus formed.
• a first category, called “solid parquet”, includes slats, or slats, individual, of small width, in solid wood.
• the other category is made up of wider slats, with a multilayer structure. More specifically, such a slat is composed on top of a noble wood facing, glued to a central core of plywood or ordinary wood, itself glued to a base plate of ordinary wood.
• the solid parquet floors are laid on joists arranged transversely to the direction of the slats.
• a laminated parquet is sometimes laid on plates, the width of which is significantly greater than that of the joists, these plates being oriented at 45 °, or substantially 45 °, relative to the longitudinal direction of the slats.
• the role of these plates is to absorb, by distributing them, the loads to which the parquet is subjected during use, so as to avoid ruptures at the level of the tabs ensuring the connection between two adjacent slats.
• the parquet floors thus formed are laid on the load distribution plates, without gluing (floating laying).
• the plates are placed on the floor, not directly, but with the interposition of a resilient underlay, for example made of foam or synthetic felt. This provides a flexible and elastic parquet, particularly suitable for the practice of certain sports such as handball and basketball for example.
• the invention relates to a laminated parquet, floating laying.
• An object of the invention is to propose a solution to the above-mentioned problem, this thanks to an extremely simple arrangement, which does not, or hardly, strike the cost price of the parquet, and which can be implemented easily at the time of his pose.
• grooves have a substantially rectangular section, dimensioned so that after crushing and hardening of the adhesive bead, it partially occupies the interior space of the groove in which it is lo ed;
• the plate is provided with a single central groove
• This angle has a value of the order of 45 °; - the slats are assembled to each other by a tongue and groove interlocking system, possibly with bonding.
• FIG. 1 is a schematic perspective view, with parts broken away, of a first embodiment of the invention, with laminated parquet;
• FIGS. 2 and 3 are partial sections of the parquet, according to the section plane II-II of Figure 4, these two views representing the parquet, respectively, before and after the installation of a slat on a distribution plate of charge ;
• FIG. 5 is a sectional view along the plane referenced N-N in FIG. 4.
• parquet slats are shown in broken dashed lines.
• the parquet illustrated in Figures 1 to 5 is a horizontal parquet called
• each slat consists of three layers, namely a facing 11, a core 12, and a sub-plate 13.
• such a slat has a length of 2.40 m, a width of 180 mm and a thickness of 15 mm.
• the upper face of the facing reproduces a frieze, which is a design of individual slats, which gives it the appearance of a classic parquet.
• two adjacent slats 10 are assembled by a conventional interlocking system, with tongue 100 and groove 101, advantageously with bonding of the tongue in the groove.
• This parquet 1 is placed on a set of load distribution plates 2.
• the plates are placed in staggered rows, as can be seen particularly in FIG. 4, to form rows, the orientation of which is such that they form an acute angle ⁇ with the longitudinal direction of the slats 10.
• this angle is equal to 45 °, or close to this value.
• the plates 2 are placed indirectly on the ground 7, in this case on a horizontal concrete slab.
• a resilient sub-layer 5 such as a synthetic foam, which itself rests on a vapor barrier film 6, for example made of polyethylene.
• each plate 2 In the upper face of each plate 2 is hollowed a longitudinal central groove 3. It is a groove of rectangular section, of shallow depth; as an indication, this depth is of the order of a millimeter.
• a bead of adhesive 4 made of elastic material, for example one-component polyurethane, is placed in the groove 3.
• This type of adhesive can be put in place easily and quickly with using a pistol.
• Figure 1 shows a bead 4 being deposited in its groove.
• the bead of glue initially has the shape of an approximately cylindrical rod, the cross section of which is chosen so that it is less than the space available in the groove.
• FIG. 4 This phenomenon is illustrated in FIG. 4, in which the double arrow F symbolizes the surface dilations and retractions of the parquet, in its own plane, transversely with respect to the slats.
• the objective in this known embodiment, is to obtain an essentially monolithic surface, by overcoming any curling forces.
• the purpose of the glue, applied with a trowel, is to ensure purely “altimetric" (anti-warping) stability of the parquet.
• the adhesive can be initially deposited in the form of a grooved layer, the grooves are crushed at the time of installation, and the adhesive layer has a uniform thickness (cf. page 7, last paragraph).
• the beads of glue allow micro-displacements of the parquet with respect to the base, avoiding the accumulation of shrinkages between the adjacent slats;
