Definitions

  • the present invention relates to a grating forming the joints between paving elements.
  • this grating is applicable to the constitution of a circulation coating on the decoupling layer in sand for example, of a waterproofing coating of a support structure such as a terrace.
  • a first technique consists in pouring a screed in cement mortar on the decoupling layer, the extent of which is divided by fractioning joints.
  • the disadvantage of this continuous screed is that it is not removable and that it is not possible to avoid demolition by breakage of the screed as a whole when a disaster related to a leak product and a verification of the waterproof coating is required.
  • a second technique consists in placing prefabricated slabs on the decoupling layer.
  • the disadvantage of these slabs is that their handling is painful because of their weight and their bulk; in addition, multiple cutouts are required to cover any surface. Consequently, this circulation coating is not very economical.
  • a third technique consists of placing plastic molds forming lost formwork on the separation layer and filling these molds on site with cement mortar.
  • the disadvantage of these molds is that they are expensive and weigh heavily on the cost of the circulation coating.
  • this technique has the advantage over the previous ones of allowing the disassembly of the slabs thus molded individually during a leakage search; moreover, the work is much less arduous and the adaptation to the shape of the surface to be covered is very easy.
  • the present invention aims to improve the third technique, by remedying its drawbacks, retaining its advantages and revealing others.
  • this grating makes it possible to form the joints in all cases and it is therefore usable, with most of the above advantages, when the paving elements, instead of being mortar slabs poured in place, are prefabricated mortar slabs, briquettes, tiles, pavers or others.
  • the grating comprises hollow rules of extruded plastic material having a section with two perpendicular axes of symmetry, in particular in the shape of a diamond, to avoid favoring a direction of installation, the nodes of crossing of these rules being obtained by interlocking them previously notched at mid-height.
  • the rules protrude, preferably when the paving elements are in mortar poured on site, on each of their longitudinal faces, two anchoring ribs inclined towards the two edges on which the considered face ends.
  • each rule is in the form of an almost flat dihedral and are connected by at least one internal stiffening partition.
  • these joints are constituted by tubular plastic profiles whose height is equal to that of the rules and consequently of paving elements, the longitudinal faces of these profiles being broken in the shape of re-entrant dihedrons.
  • Each longitudinal face of the profiles forming fractioning joints is connected to the edges by beaked edges allowing the anchoring in the mortar and the attachment of the lateral ribs of a possible contiguous rule.
  • tubular profiles forming fractioning joints cooperate, in the corners, with studs whose sides of their square section have a width equal to the thickness (E) of these profiles and whose height is equal to that of the latter.
  • Each stud is made integral, by a sole in particular, with four screeds shaped for the interlocking of the tubular profiles forming fractioning joints.
  • 1 designates a reinforced concrete terrace slab, 2 a low wall surrounding this terrace and 3 a rim with a drop of water protruding inside the low wall.
  • the slab 1 and the wall 2 are covered by a sealing coating 4. on which is deposited a layer of decoupling 5, made of sand for example.
  • the surface to be protected is divided by fractioning joints 6 into several base surfaces 7 (square or rectangular) in each of which are arranged gratings 8. These are constituted by rules 9, 10 identical to each other and crossing at a right angle in order to delimit elementary square spaces 11 having the volume of a slab. Cement mortar is then poured into these spaces in order to form, after setting, slabs 12 perfectly attached to the rules 9, 10 and to the fractioning joints 6.
  • each rule 9, 10 of a grating 8 is constituted by a hollow tubular profile in extruded plastic. Its section is symmetrical along two perpendicular axes of symmetry V and H; in the example shown, this section has the shape of a diamond; as soon as this condition is fulfilled, no precaution should be taken to machine and set a rule, because no differentiation appears between the top and the bottom, between the left side and the right side; it follows that the notching described in the following to be able to cross the rules ( Figure 2) can be performed from any edge 13, 14 of a rule and that to carry out interlocking, it suffices simply to present the rules 9 with their notches 15 open at the bottom and the rules 10, absolutely identical to the previous ones, with their notches -16 open at the top.
  • each rule 9, 10 comprises two edges 13, 14 whose width "e” corresponds to that of the joint to be formed between the slabs 12, and two longitudinal walls 17, 18 shaped as relatively flat dihedrons projecting outwards, the height "h” of this rule being equal to the thickness of the slabs 12.
  • the tubular profile constituting these rules being hollow, it is deformable in a relatively elastic manner, which allows it to compensate for the shrinkage of the mortar when it is taken after pouring the slabs, which also allows it to constitute an effective expansion joint intervening in a leaktight manner both during a rise and a lowering of the ambient temperature.
  • the rules should not be too flexible; on the contrary, they must have a certain stiffness, a certain spring.
  • the longitudinal walls 17, 18 are connected, in the example chosen, by two small internal partitions 19, 20 coming from extrusion.
  • each rule must be well anchored in the mortar to perfectly follow the aforementioned dimensional variations, which are very small, moreover, of the slabs. Consequently, the longitudinal walls 17, 18 of each rule have protruding ribs 21 and 22, 23 and 24 inclined outward and the two edges 19 and 20 respectively.
  • the notches 15, 16 are absolutely identical and machined at mid-height "h / 2" over a width corresponding substantially to the average thickness of the rules. Given the aforementioned symmetry that this tapping also respects, all the rules can be tapped at the same time without any respect for the direction of presentation; to make a crossing node, it suffices, as shown in Figure 2, to present the rules 10 with their notches 16 open at the top and perpendicular to the rules 9 with their notches 15 open at the bottom, putting these notches 15 and 16 facing each other, then bringing said rules together to fit into said entaitles, the solid parts 25 and 26 that these let exist.
  • the aforementioned fractionation joints 6 are also constituted by tubular profiles made of extruded plastic, the height h of which is equal to that of the rules 9, 10 and therefore the thickness of the slabs 12.
  • These tubular joints 6 have edges 27, 28 and longitudinal walls 29, 30 which are shaped as relatively flat dihedrons, returning inside said joints.
  • the edges 27, 28 are connected to the walls 29, 30 by beaked edges 31 provided to ensure, in cooperation with the re-entrant conformation of said walls, effective anchoring in the mortar of the slabs; in addition, these edges are positioned so that the ribs 21 to 24 of the rules 9, 10 can hang there when it is necessary, due to the shape and the particular dimensions of the terrace, to place side by side a split joint and a ruler.
  • Each joint crossing node 6 delimiting the base surfaces 7 makes use of a stud 32 illustrated in FIG. 4.
  • This stud has a square section the sides of which have a width "1" equal to the thickness "E" of the joints so that the faces of the studs rigorously extend those of said joints further, the height h of this stud is equal to that of these joints, so that the top of the studs is flush with the visible face of the paving.
  • Each stud 32 is made integral, by a sole 33 for example, of four orthogonal yokes 34 to 37 extending to limited height and intended to receive, for centering, the ends of the fractionation joints 6 which terminate there.
