Definitions

  • the present invention relates to a support pad for floor covering tiles.
  • Prefabricated slabs in particular concrete, used for floor coverings subject to pedestrian and / or vehicle traffic can be placed on pedestals.
  • each slab angle rests on a pad common to different neighboring slabs.
  • this installation method requires the use of slabs of mechanical resistance markedly higher than those of slabs on uniformly distributed supports (sand, mortar, etc.).
  • the present invention aims to provide a pad allowing the use of slabs having a mechanical resistance significantly lower than that currently required to meet the regulations in force concerning floor coverings formed by slabs placed on studs.
  • a stud comprising, in accordance with the invention: a central patch, an outer ring surrounding the central patch and spaced from it, and connecting elements connecting the central patch to the crown, the outer crown and the central pellet having substantially coplanar upper support surfaces, and the crown having an apparent modulus greater than that of the pellet.
  • the resistance P STA is for example determined during a rupture test carried out by applying a static load to the center of the supported slab along two opposite edges.
  • the resistance P DYN is for example determined during a rupture test carried out by application of a load dynamic (vehicle wheel arch, for example) on the slab on studs under normal installation conditions.
  • the studs according to the invention make it possible to very clearly increase the ratio P DYN / P STA 'increase of up to 100%. It is therefore understandable that, in order to maintain the same dynamic resistance, a static resistance which is much lower than that hitherto necessary is sufficient, hence an appreciable saving in material.
  • This increase in the PDYN / P STA ratio is due to the presence of the crown which makes it possible, for each slab, to reduce the free distance between rigid supports.
  • the central patch which is less rigid than that of the crown, it certainly helps to support the slab, but also has the particular function of ensuring stability at angles and making up for any dimensional irregularities, the probability of existence of the latter being stronger in the peripheral part of the slab and in particular at the corners.
  • the distance d between the center of the stud and the outer edge of the crown, measured along the location on the side of a slab is between L / 4 and L / 2, L being the length of said side of slab.
  • the crown has a symmetrical shape with respect to the vertical axis of the patch, for example a circular or polygonal shape.
  • the distance d defined above may take different values when it is measured along two different sides of the slab.
  • the crown can then have the shape of an ellipse or an irregular polygon.
  • the pad 10 illustrated in FIG. 1 is constituted by a central patch 11, an outer ring 12 and radial link arms 13 connecting the patch 11 to the outer ring 12.
  • the central patch is cylindrical in shape, with a diameter of between 40 and 60 mm approximately. It has on its upper face two cross ribs 14 forming slab dividers.
  • the outer ring 12 is circular in shape with the same vertical axis of symmetry as the patch 11.
  • the thickness of the ring 12, measured radially is a few mm, for example approximately 6 to 15 mm. This thickness increases slightly, for example from 1 to 3 mm, from the upper face to the lower face of the crown.
  • Several notches 15 are formed in the crown 12 from its underside to allow the circulation of water on the ground when the stud is placed.
  • other notches 16, four in number are formed in the crown 12, from its upper face, in alignment with the separators 14.
  • the notches 16 form incipient fractures for cutting the stud when it must be placed along one side or at an angle to the floor covering to support only one, two or three tiles.
  • the notches 15 are located at the notches 16 to also facilitate cutting of the stud.
  • the connecting arms 13 are for example four in number, making between them angles of 90 ° and spaced both from the upper plane of the stud in which the slab support surfaces are located and from the lower plane in which the ground support surfaces.
  • Each link arm 13 extends radially from the patch 11 and is connected to the crown 12 substantially halfway between two notches 16.
  • the crown 12 has an apparent modulus greater than that of the patch 11.
  • the stud is molded in one piece from a rigid plastic material such as polyethylene or polypropylene and the least hardness of the pellet 11 is obtained by forming therein a central recess 11a from its underside.
  • the crown 12, the arms 13 and the lower part of the pellet 11 are molded in one piece from a rigid plastic material while the upper part 11b of the pellet 11 is an insert glued in a different flexible material such as an elastomer.
  • each slab 30 rests on four studs and each of these supports the slab on the one hand, by means of the pad 11, at an angle 31 of the slab and, on the other hand, by means of the crown 12, along an area 32 spaced from the angle 31.
  • the crowns 12 have an outside radius d relatively large compared to the radius r of the pellets 11. In this way, as shown in FIG.
  • the rings 12 of the four studs supporting the same slab provide the latter with rigid supports in zones 32 spaced apart from one another by a distance considerably less than that separating the zones d 'support 31 on the pellets 11.
  • the outside radius d of the rings 12 is between L / 3 and L / 2, L being the length of the side of the slab assumed here to be square.
  • the tiles are generally square in shape and 30, 40 or 50 cm side, although the support function of the tiles is mainly provided by the crowns 12, the pads 11 are essential to ensure the stability of the tiles at the corners and to make up, thanks to their less rigidity, for any peripheral irregularities in the slabs.
  • the crown 12 can have the shape of a polygon symmetrical with respect to the axis of the stud.
  • the distance d is measured between the center of the stud and the outer edge of the crown 12 in alignment with the separators of slabs 14.
  • the crowns 12 can have different distances along two neighboring separators, this distance preferably always remaining between L / 2 and L / 4, L being the length of the side corresponding slab.
  • the regulations impose studs with different bearing surfaces on the ground depending on the nature of the support and different heights depending on the surface of the ground to be covered. This can be obtained either by using studs 10 of different sizes, or by completing the stud 10 by means of a complementary piece 20 as shown in FIG. 5.
  • the piece 20 molded in one piece from a rigid plastic material has a shape similar to that of the stud 10 with a central pad 21, an outer ring 22 provided with notches 25, 26 and link arms 23.
  • the face upper part of the pad 21 is flat while the upper face of the crown 22 has a central annular rib 27.
  • a corresponding groove 17 is formed in the lower face of the pad 10.
  • the thickness of the slab may require the use of height adjustment shims interposed between the stud and the slab.
  • shim construction Several examples of shim construction are shown in Figure 7.
  • a first wedge 40 is intended to be disposed only between the patch 11 and a slab angle.
  • This wedge has the shape of a sector of 90 ° with the same external radius as the pad 11 and fitting between two separators 14.
  • lugs 41 can be provided along the radial edges of the shim 40, these lugs penetrating into corresponding housings 18 provided in the vertical edges of the separators 14.
  • a second wedge 50 is intended to be interposed between the crown 12 and the slab.
  • the wedge 50 is a 90 ° annular sector with a U-shaped section so that it can be placed astride the upper edge of the crown.
  • One of the radial edges of the wedge 50 is closed by a wall 51 penetrating into a notch 16. Thus, the wedge 50 is blocked radially and in rotation about the axis of the stud.
  • This shim 60 also has a 90 ° sector shape and includes lateral pins 61 similar to the pins 41 of the wedge 40 and, at the end of one of the radial edges, a part 62 projecting laterally and below to engage in a notch 16 of the same way as the wall 51 of the wedge 50.
  • the wedge 60 is thus effectively blocked in the radial direction and in rotation about the axis of the stud.
