Definitions

  • the present invention concerns a prefab concrete tile having drainage holes, in particular a concrete tile including a plurality of inserts defining the drainage holes extending from an upper surface of the tile to a lower surface of the tile.
  • Concrete pads are very durable and used in a variety of applications such as walkways, driveways, parking's and the like.
  • concrete surfaces are formed by preparing a surface on which concrete is to be poured and subsequently constructing a casing about the periphery of the concrete slab to be laid. It is known to provide such concrete pads with means to allow water drainage.
  • a grid of cones is provided in the casing prior of pouring the concrete.
  • concrete pads can also be realized by laying concrete tiles. This offers the advantage that the concrete can be poured in a controlled environment of a production site and that the concrete surfaces can be finished (or smoothened) to a higher extend than is possible with in-situ poured concrete. Moreover, such tiles can easy be removed and re-used.
  • the present invention is defined in the appended independent claims. Preferred embodiments are defined in the dependent claims.
  • the present invention concerns a prefab concrete tile comprising:
  • the inserts protrude from the lower surface of the concrete slab, wherein the section of the inserts protruding from the lower surface of the concrete slab may be perforated or comprise a water discharge opening in their wall part.
  • Said grid may partially protrude from the bottom surface to the concrete slab.
  • each height adjustment means comprises an actuation point to allow adjusting the height of the particular height adjustment means, which actuation point is accessible by inserting a tool in the concerned hole.
  • the present invention relates to a concrete tile, poured and dried prior to laying the tile on a desired place to form a concrete access surface.
  • Fig. 1 schematically illustrates a prefab concrete tile according to a first aspect of the present invention, the tile comprising a concrete slab having an upper surface configured to form an access surface for pedestrians and/or traffic, and a lower surface opposed to the upper surface.
  • Embedded in the concrete slab and as shown in Fig. 2 is a plurality of inserts defining holes, in particular cones extending from the upper surface to the lower surface of the slab.
  • the cones are oriented such that their cross-sectional area increases from the upper surface of the tile towards the bottom lower surface of the tile. This however does not exclude that the upper surface of the tile can be chamfered at the interface of the concrete and an upper edge of each insert, thereby creating a through hole through the tile with a double conical structure, in particular a small cone with diminishing cross sectional area extending from the upper surface of the tile to several millimeters (1 to 10 mm) below the upper surface and a larger cone defined by the inserts.
  • the inserts can also be made as double conical structures with a sidewall defining a small cone with diminishing cross sectional area on top of a larger cone with increasing cross sectional area such that the inserts extend from the upper surface of the tile to below the lower surface of the tile.
  • the inserts preferably protrude from the lower surface of the concrete slab to form a support for the tile.
  • the protruding part of the inserts may be embedded in a surface whereon the tiles are laid or can actually support the tile, leaving a space between the lower surface of the concrete slab of each tile and the ground there below, which space can function as a water buffer.
  • the protruding insert part preferably has a perforated wall or a wall part with a non-continuous lower rim such as to allow a waterflow out of the insert under the concrete slab into the water buffer.
  • the inserts are preferably arranged and connected to one another in a grid structure, with grid members extending between neighboring inserts.
  • Such grid structure is beneficial in immobilizing the inserts in a casing when pouring concrete to produce the concrete tile and may act as a concrete reinforcing.
  • the grid members can be configured as battens and may protrude from the lower surface of the concrete slab in a finished concrete tile of the present invention.
  • the inserts may comprise longitudinally oriented slits, such that the inserts can be slid over the grid structure, preferably at an intersection of the grid such as to fix the inserts in place on the grid.
  • the inserts are preferably manufactured in a polymeric material selected from the group comprising: preferably polyethylene, polyester or polyethylene terephthalate or polyethylene naphthalene, polyoxymethylene and or admixtures thereof.
  • all inserts are oriented in the same way, meaning that all inserts define an conical through hole through the tile whereby the cone is oriented such that the cross-sectional area increases from the upper surface of the tile towards the bottom lower surface of the tile.
  • the wall of the inserts at the upper surface of the concrete slab (or in case of a chamfer at the interface of the concrete and an upper edge of each insert) hereby defines the smallest cross-section of the cones and is preferably comprised between 0,10 and 3,5 cm 2 , whereas the cross-section at the bottom of the insert, which is the largest cross-section of the cone is comprised between 1,5 and 55 cm 2 .
  • the inserts can be filled with a water impermeable filler material such as a mixture of stones of different dimensions to create a kind of water filter, without the risk that the filler material or stones, sand, earth, or accumulated litter splashes from the holes to the upper surface of the concrete tile under influence of impinging water droplets.
  • a concrete tile according to the present invention preferably comprises between 20 and 400 inserts per m 2 .
  • the openings by perforation of the wall of the inserts or the openings created therein by the non-continuous lower rim are preferably dimensioned small enough to prevent the filler material from migrating through these openings, yet these openings are dimensioned large enough to prevent easy clogging.
  • the openings may be designed with a non-circular edge, eg. a square, oval or irregular shape.
  • the present invention also concerns a prefab concrete tile comprising:
  • the inserts can have any kind of cross-sectional design, and can be configured as for example a conical shape or a straight tube.
  • the wall of the inserts at the upper surface of the concrete slab is preferably comprised between 0,10 and 3,5 cm 2 .
  • a concrete tile according to this aspect of the invention preferably comprises between 20 and 400 inserts per m 2 .
  • height adjustment means are provided in at least three inserts of a tile, each positioned such as to form a triangle enclosing a maximal surface area of the tile.
  • more height adjustment means per tile can be provided.
  • the adjustment means preferably comprise on the one hand a first piece that is fixed to the grid and on the other hand, a base piece that engages with the first piece and is movable in view of that first piece.
  • the first piece can for example be configured as a hollow ring or circular tube comprising an inner thread, whereas the base piece is in that case configured as a rod with an outer thread engaging the inner thread of the hollow ring or tube, such that by rotating the base piece, this base piece shifts in a longitudinal direction of the holes (normal to the surface of the concrete tile).
  • the first piece is preferably fixed to the inserts or to the grid structure connecting a plurality of inserts. The connection can be achieved by providing the first piece at one or more intersections of the grid as shown in Fig. 6 whereafter the inserts as shown in Fig. 5a or 5b can be slid over the grid such that the first piece is located inside the insert.
  • the first piece and the base piece are preferably positioned along the central axis of the holes, whereby the base piece comprises an actuation point such as a screwhead allowing rotating the base piece in the first piece of the height adjustment means by inserting a screwdriver in the concerned hole and thereby allowing adjusting the position of the base piece versus the first piece and hence the concrete slab of the tile.
  • an actuation point such as a screwhead
  • the base piece in this case comprises an end portion that defines the actual support of the tile.
  • the height adjustment means may comprise a first piece that is connected to the inserts by and intermediate bush ring, such that the first piece is locked in position versus the insert but can freely rotate in view of the insert.
  • actuation of the height adjustment means can be performed by rotating on the first piece to obtain a vertical movement of the base piece in view of the inserts.
  • the end portion of the base piece defining the actual support of the concrete tile may comprise a roughened surface or a kind of protruding pins preventing the base piece from rotating in view of the underfloor.
  • the first piece may be configured as a tube with a closed upper end that where the actuation point can be provided. The screw thread of the first piece is as such protected from direct impact from optional stones, sand, or litter present in the insert.
  • the first piece of the height adjustment means can be provided on the grid structure outside of the inserts, whereby the first piece is formed integrally with the battens or provided on the battens by welding, an adhesive or by a mechanical coupling such as a clip connection.
  • the base piece can be a foot structure provided on a threaded bolt with a screw thread configured to cooperate with the screw thread in the first piece.
