Definitions

  • the invention relates to a slab for flooring and to a floor formed from slabs of this type.
  • Some floor tiles are made of a polymer-based material. These slabs are generally square or rectangular and have a relatively small thickness relative to their surface. In general, they have a thickness of between 4 mm and 12 mm for an area of about 0.25 m 2 . These slabs are relatively flexible and easy to install on a rigid support, for example a concrete screed.
  • connection members male and female type, allowing their assembly to achieve a floor covering, without the need to stick each slab on the rigid support.
  • US-2005/0166513 discloses slabs, polymer, provided on their edges of triangular reliefs, alternated with housing of complementary shape. The housing and the reliefs are arranged so as not to change the nominal thickness of the slabs. For this, the edges equipped reliefs and housing have a thickness less than the central part of the slabs.
  • DE-A-1 9640 128 describes floor tiles with a thinner area on their sides.
  • One side includes a raised area provided with housing, regularly spaced and arranged parallel to a groove.
  • An opposite side comprises a relief, of shape corresponding to the groove, and a groove, of shape corresponding to the relief located on the other side.
  • This groove is provided with regularly arranged housing and complementary shape to that of the recesses in the relief located on the other side.
  • slabs provided with connecting members, generally configured T, extending outwardly. These organs are adapted to fit into housing of complementary shape defined between two neighboring reliefs equipping another identical slab.
  • Such slabs are, for example, those marketed under the name "TRAFICLINE” (registered trademark) by the company TLM.
  • the invention more particularly intends to remedy by proposing a slab enabling a floor covering to prevent infiltration of liquid.
  • the invention also relates to a floor covering made from slabs conforming to one of the preceding characteristics.
  • Slab 1 shown in figure 1 is made of a polymer-based material, for example from a polyvinyl chloride (PVC) compound.
  • this slab is in the form of a parallelogram, preferably a square, with dimensions of between 30 and 60 cm. for a thickness of between 7 mm and 10 mm.
  • the visible face 2 of the slab 1, once it is in place on a support, is designated as the upper face of the slab.
  • this face 2 is smooth and united. In other embodiments not shown, it is granular or rough, for example to imitate the appearance of the stone or the grain of the leather. It can also have reliefs of suitable shapes to improve the anti-slip properties of the slab.
  • Each tab 5, 6 has a thickness e less than the nominal thickness E of the slab 1, that is to say the thickness of the slab 1 in its central part. In this case, for a slab 1 of thickness E, in its central part, between 7 mm and 8 mm, each tab 5 or 6 has a thickness e of between 3 mm and 4 mm.
  • Connecting members of the same type are provided on each of these tabs 5, 6 and oriented towards the upper face 2 of the slab when the latter is in place on a support.
  • the legs 5, 6 are equipped with female type connecting members.
  • tabs 5, 6 are joined at a common corner 7 to the edges 3 and 4, formed by the ends 8, 9 of the legs 5, 6.
  • the common corner 7 of the legs 5, 6 is provided, generally in a central position , of a well 17 with a circular section.
  • the female-type connecting members comprise, in the part of each tab 5, 6 farthest from the main body 100 of the slab 1, a groove 12.
  • This groove 12 extends over almost the entire length L 5 , L 6 of the leg 5, 6.
  • the groove 12 is open upwards and with a rounded bottom.
  • each tab 5, 6 is equipped with a row 13 of housing 14. This row 13 is parallel to the groove 12.
  • the housing 14 are regularly spaced. They are elongated, with rounded and bulging ends with respect to the central portion 16 of the housing 14. In other words, these housings 14 have generally a shape approximating that of a bean.
  • Each lug 5, 6 is equipped, in the middle, with an area 18 without groove 12 and with housings 14. This zone 18 without a connecting member extends, centrally, over the entire width of lug 5, 6. Area 18 is generally rectangular in shape. The thickness of the tab 5, 6 at this zone 18 corresponds to a minimum thickness of the tab 5, 6.
  • tabs 5 and 6 are set back from the adjacent edge of the slab.
  • the legs 5 and 6 have lengths L 5 and L 6 less than the length L 1 overall on one side of the slab 1.
  • the ends 10, 11 of the legs 5, 6 define, with reference to the figure 1 , with respectively the edge 19 represented in the upper and right part, and the edge 20, shown in the upper and left part of the figure 1
  • This cutout 21, created by the difference between the lengths L 5 and L 6 , on the one hand, and the length L 1 , on the other hand, is generally of square shape, of dimensions corresponding to those of the corner 7.
  • edges 19, 20, visible from the upper face 2 of the slab 1, are in fact legs 19, 20 of dimensions similar to the legs 5, 6. At the figure 1 only the upper face of these tabs 19, 20 is visible. This face is coplanar with the face 2 of the slab 1. Thus, there is a continuity of appearance and material between the main body 100 of the slab 1 and the tabs 19, 20.
  • These tabs 19, 20 are equipped, on their lower faces intended to be turned towards the ground, connecting members of the same type, different from the type of connecting members of the legs 5, 6.
  • These male-type connecting members are not visible from the upper face of the slab 1.
  • the tabs 19, 20 are particularly visible at the figure 3 where the lower face 22 of the slab 1 is shown.
  • a row 23 of reliefs 24 elongated and regularly spaced.
  • the ends 240 of the reliefs 24 are rounded and swollen with respect to their central part.
  • the shape and distribution of these reliefs 24 correspond to the shape and distribution of the housing 14 located on the legs 5, 6 of the slab 1.
  • rows 23 of reliefs 24 are arranged on the tabs 19, 20 in the part which is farthest from the body 100 of the slab 1.
  • the ring 25 is disposed parallel to the row 23 of reliefs 24.
  • the male-type connecting members of a slab 1, namely the reliefs 24 and the rod 25, are adapted to be inserted into housing 14 and corresponding groove 12 which form the female type connecting members of another slab 1 identical.
  • each square slab 1 is provided, on two adjacent sides with lugs 5, 6 equipped with connecting members 12, 14 of female type on their upper faces and, on the other two sides, lugs 19, 20 equipped with connecting members 24, 25 of male type on their lower faces.
  • the female-type members are oriented in the direction of the upper face 2 of the slab 1, the male-type members are oriented towards the lower face 22 of the slab 1. In a variant not shown, the orientation of these reliefs can be reversed.
  • the arrangement of the male and female type members is adapted so that there is overlap between the tabs 5, 6, 19 and 20 during the connection between slabs 1, without changing the nominal thickness E of each slab 1.
  • the wedge 26 formed by the junction of the ends 27 and 28 of the legs 19 and 20 is provided with a male-type connecting member, namely a pin 29.
  • This pin 29 is cylindrical, circular section and is located on the same face of the legs 19, 20 that the reliefs 24 and the rod 25.
  • the pin 29 is adapted to fit into a well 17 of complementary shape, as described above, which is on a corner 7 of another slab 1.
  • the pin 29 and the well 17 makes it possible to precisely position two slabs 1 during their assembly, serving as a keying and guide.
  • the pin 29 and the well 17 guarantee a good pairing of the complementary connecting members between two slabs to be joined, by orienting the latter.
  • each slab 1 is equipped at the periphery with zones 30 of extra thickness, regularly arranged. These zones 30 are advantageously of rectangular shape, with rounded corners. On the sides of the slab 1 provided with the tabs 19, 20 these zones 30 are formed so that one of their sides is adjacent to the edge 31 of junction between the body 100 of the slab 1 and the tabs 19, 20. This edge 31 being parallel to the rod 25.
  • a zone 32 devoid of connecting members, is made in excess thickness over the width of the tabs 19, 20, in the central portion.
  • the main body 100 of the slab 1 is also equipped on its lower face 22 with zones of increased thickness. These zones comprise two rows 34 of elongate reliefs 35, generally rectangular and with rounded corners, arranged in a cross around a central relief 36, generally square with rounded corners. Each quarter of the slab 1, delimited by the rows 34 of reliefs 35 and the zones 30, is equipped with several parallel rows 37 of studs 38 of support to the ground, regularly spaced. These studs 38 are cylindrical with circular section.
  • the contact surface between the ground and the slab 1 is therefore relatively small since the slab 1 rests on the ground only by the zones 30, the elongated reliefs 35, the central relief 36 and the studs 38.
  • the contact with the ground takes place only about 42% of this area.
  • flow channels 39 are defined allowing the free circulation, under the slab, of a liquid, for example water. These channels 39 are located between the peripheral channels 33.
  • the channels 33 and 39 avoid or, at the very least, limit the stagnation of liquid between the slabs and the ground.
  • each slab 1' is equipped with pads 40, of different shape of the pads 38.
  • the pads 40 are cruciform.
  • the elongate reliefs 35 are replaced by reliefs 41, generally of rectangular shape. These rectangular reliefs 41 on their short side have lugs 42.
  • the central relief 43 is, in this case, a square whose corners are cut.
  • the zones 44 in overthickness are rectangular with square corners.
  • the distribution of reliefs 40, 41, 43 and zones 44 is similar to that previously described. In other words, these reliefs 40, 41, 43 and these zones 44 also define between them flow channels 47, 48.
  • male-type connecting members namely pins 50
  • pins 50 are arranged between some of the reliefs 24.
  • three pins 50 are regularly distributed on each side of a slab 1 ".
  • the space between a relief 24 and a pin 50 is greater than the space between two adjacent reliefs 24.
  • These pins 50 are of generally frustoconical shape with a free end 500 equipped with an annular relief or bead 501.
  • the pins 50 are intended to be inserted into housing 51, of complementary shape, arranged between housings 14 adapted to receive the reliefs 24.
  • the housings 51 are formed by through orifices, one end of which is provided with an annular groove 510 adapted to to receive the bead 501.
  • the presence of these pins 50 and of these housings 51 makes it possible to improve the connection between two slabs 1 "terraces, thus making the pins 50 in the housings 51 fit, the sealing being ensured by the throat 510 and the bead 500.
  • a countersink 52 is formed on two adjacent sides 53, on the visible face 54 of the slabs 1 "when the latter are assembled.
  • This countersink 52 with a depth of approximately 1 mm and a width of approximately 3 mm, extends along the entire length of two adjacent sides 53 of the slab 1 ".
  • a regular grid formed by countersinks 52 of slabs 1" joined, appears.
  • the ring 25 of the first embodiment is here replaced by a bar 45 of rectangular cross section.
  • the reliefs 24 are replaced by small bars 46.
  • the constituent housings of the female connecting members have shapes adapted to receive these bars 45 and 46.
  • the pin 29 of circular section and the corresponding well 17 arranged in the corners, 26 respectively 7, connecting the edges of the legs 5, 6, 19, 20 provided with connecting means of the same type may be of another form, for example triangular. We can also consider the presence of two pions circular section.
  • Such a connection system between the slabs is not visible from the upper face 2 of the slabs 1, 1 ', 1 "when they are joined, because of the overlap of the tabs 5, 6 and 19, 20. Only a line of joint, frank, between two slabs 1, 1 'is visible by the user.Therefore, the slabs 1, 1', 1 "can receive a weld bead, known per se and not shown. Such a weld bead, for example PVC, forms a thermoplastic seal between the slabs 1, 1 ', 1 "and improves the sealing of the floor covering, as well as its finish.
  • An impression, unitary, of the upper face 2 of each slab 1, 1 ', 1 "makes it possible to produce a predetermined pattern, once the slabs have been assembled.
  • This impression may represent a decorative pattern or imitate a material such as stone, marble or wood.
  • edge of the floor covering may be provided with an inclined threshold or ramp.
  • a chamfer is made on the free edges of certain slabs when they are in position.
