Definitions

  • the present invention can be included within the technical field of construction; particularly, in the technical field of cladding of floors, walls and ceilings with rigid plates.
  • the object of the invention relates to a device for levelling rigid cladding plates.
  • cladding plates such as pieces of ceramic, floor tiles and others of appreciably uniform thickness on floors, walls or other surfaces
  • a layer of adhering product is disposed on said surface (such as mortar or adhesive) whereon said cladding pieces are placed.
  • This operation requires a certain accuracy by the person placing the plates, so that the surface clad later remains smooth, aligned and levelled. This process is slow and complicated.
  • Each plate must be placed, levelled and made flush with the adjacent already placed parts, individually and using completely traditional methods.
  • the levelling of cladding plates is performed using the traditional system, i.e. once the mortar or adhesive has been placed on the base surface where the cladding plates will be placed, the first cladding piece is placed and, using a spirit level, its position is controlled with no further aid or tools. If the part is uneven, its position is corrected by tapping it with a rubber mallet. This work is performed repetitively for all the cladding parts to be placed, being difficult and complicated, since the person performing the task must work in unnatural postures during full working days, especially in the case of floor claddings.
  • the levelling member has an inverted T-shape, with a lower section in the form of cylindrical segment and a flat upper section perpendicularly joined to the central area of the concave part of the lower section.
  • the upper section comprises an opening, as well as incorporating, close to the joint with the lower section, a notch in the side ends, which weakens the resistance to shearing stresses.
  • the wedge comprises a settling surface and a working surface, inclined with respect to the settling surface, and equipped with teeth and is adapted to be housed, at least partially, in the opening.
  • the adhering product is applied on the surface to clad and the levelling pieces are disposed with the convex part resting on the surface.
  • the cladding plates are disposed, taking care that for each joint defined by two adjacent plates one of the plates is disposed on each side of the upper section of at least one levelling member.
  • the wedge is introduced in the opening, tapping said wedge so that the working surface produces efforts on the upper part of the opening, tending to separate the levelling member and the surface to clad, which will also cause the separation of the cladding plate, being levelled.
  • the adhering product is dry, an impact is made on the upper section, which thanks to the notches, is separated from the lower side, the upper section being disposable, as well as the lower section being buried beneath the cladding plates, and concealed, once the grouting has been applied to seal the joints.
  • the wedge can be introduced in the opening by means of a hammer or a metal pushing tool.
  • the tool comprises a working head having a support surface that is arranged, in use, next to a face of a portion of the device.
  • the working head has a side opening through which the band member, connected to a portion of the device and protruding from the second portion through two tiles, is arranged according to the working head.
  • the tool comprises, furthermore, tensioning means that is adapted to engage with the band member and to apply on it a tension in order to arrange the device between a first position, in which the distance between the first portion and the second portion is larger than the thickness of the mentioned tiles, and a second position, in which the distance between the first portion and the second portion is equal to the thickness of the tiles. And the second portion pushes the tiles against the first portion in such a way that it brings them to a same level.
  • the application GB2404388 describes a wedging device for securing lead flashing in a slot between two adjacent rows of brickwork.
  • the wedging device comprises two wedges of similar slope arranged such that the thin end of the wedges overlie, each wedge having a retaining means and a non-return means.
  • the retaining means is a dovetail rib and groove and the non-return means a series of ratchet teeth.
  • the retaining means keeps the two wedges together while allowing movement along the line of greatest slope and the rachet teeth prevent movement in a direction which decreases the combined thickness of the wedges.
  • the wedges may be identical or different, in that one is provided with a retaining groove and the other with a retaining rib.
  • the wedges may have longitudinal ribs which in use resist removal of the expanded device from a slot. Also disclosed is a tool for inserting the device into a slot and then increasing the combined thickness of the wedges and a method of using the wedges.
  • the present invention resolves the drawbacks mentioned, by means of a device for levelling rigid plates, such as floor tiles or ceramic tiles, of those used for the cladding of surfaces, such as floors, ceilings or walls.
  • the device of the invention comprises a levelling member, a wedge, and a first actuation member.
  • the levelling member is T-shaped and comprises a preferably flat base, even more preferably rectangular, adapted to be disposed on and adhering product, such as mortar or glue, suitable for fixing the cladding plates to the surface to clad, as well as additionally comprising a second flat member perpendicularly joined to the base defining collinear edges for joining between the base and the second member.
  • a flat base is preferable because it provides a greater contact surface between the base and the cladding plate and, therefore fewer and more uniform stresses on the base due to contact with the cladding plate.
  • the base may additionally incorporate cylindrical stiffeners, preferably in the form of a cylinder sector, such as a semi-cylinder, as well as brackets connecting the cylinders to improve the base's resistance.
  • the ends of the base furthest from the second member may have a more reduced thickness, to facilitate the insertion of said base under the cladding plates, and in the corners of said ends furthest from the second member, there may preferably be bevels to lighten material, considering that the part transmitting greatest efforts is the part closest to the second member.
  • the second member is adapted to transmit towards the base a component of the efforts exerted on said second member; said component is in a direction perpendicular to the surface to clad and towards the outside of said surface to clad. Therefore, the second member is equipped in its lower part with a first opening, wherein the wedge can be inserted.
  • the first opening is also limited in its upper part by a flange designed to make contact with the wedge.
  • the height dimension of the first opening is related to the maximum height allowed for a cladding plate.
  • the second member may comprise protuberances to provide the original thickness of said second member with an additional thickness, suitable for joining cladding plates according to joints of greater width than the original thickness of the second member.
  • the protuberances may be disposed on the front part and/or the rear part, and they may have varied thicknesses, enabling the production of levelling parts which allow making joints of various thicknesses between cladding plates.
  • the second member may incorporate ribs disposed from side to side to provide greater resistance.
  • the second member incorporates at its ends, close to the joining edges, notches designed to produce a weakening against shearing stresses.
  • the dimensions of said notches shall not be so large as to produce an appreciable weakening against tractive efforts.
  • the levelling member is manufactured in injected plastic, due to the simplicity of preparation that said technology provides, as well as due to its convenience in terms of cost.
  • the cladding plates are disposed on the surface to clad, so that each of the sides of two adjacent plates which define a joint is disposed on at least one base, with each of the two plates disposed on one side of said base with respect to the second member, where the edges for joining are disposed in substantially the same direction as the joint.
  • the wedge comprises a flat settling surface designed to be inserted in the first opening and resting on the cladding plate, as well as comprising a working surface, which is inclined with respect to the settling surface; said working surface is preferably equipped with a series of grooves which define saw teeth, to block the backward movement of the wedge, where the working surface is adapted to transmit the component of the efforts exerted by the user on the levelling member through the base's flange, causing efforts tending to separate the base and, therefore, the cladding plates, from the cladding surface, for levelling the cladding plates.
  • the wedge is a body in the form of straight triangular prism, where the settling surface is one of the side faces of the prism and the working surface is another of the side faces of said prism.
  • the number of teeth is defined by a compromise bearing in mind that a high number means greater accuracy in the levelling, but less resistance of the teeth.
  • the first actuation member is a manual tool comprising a support, a third support member and a pusher.
  • the support is a longitudinal part comprising at a first end a handle adapted to be gripped by a user, as well as comprising at a second end, opposite the first end, a scale graduated in correspondence with the height of the cladding plate, where the scale has a first frame corresponding to the smallest plate height allowed, a second frame corresponding to the greatest plate height allowed and third frames corresponding to intermediate plate heights.
  • the scale makes it possible to apply a suitable pressure for the thickness of the cladding plate. Without the regulation with respect to plate height, the device would apply insufficient pressure for the case of reduced height, whilst it would apply an excessive pressure to plates of large height, causing them to break.
  • the third support member comprises a guide adapted to allow the displacement of the third member along the support, between the positions corresponding to the first frame and the second frame.
  • the third member can further preferably comprise fixing means for fixing said third member in a desired position in the support.
  • the fixing means comprise a screw that can be screwed in a threaded bore that connects with the guide, so that the screw, when screwed / unscrewed, can press / stop pressing the support against the guide, avoiding / allowing the relative movement between the third member and the support.
  • the third member comprises first legs disposed in the lower part, separated by a second opening which allows the passage of the wedge, and adapted to provide a distancing between the support and the cladding plate.
  • the first legs further comprise feet to rest on the cladding plate, the dimensions whereof are preferably sufficiently large to avoid said feet from being introduced in the joints between cladding plates.
  • the pusher is articulated with the support according to an articulation and comprises a first gripping portion to, in cooperation with the handle of the support, actuate the pusher between a first position and a second position, and a second pushing portion adapted to remain out of contact with the wedge in the first position and push the wedge against the flange of the levelling member, transmitting towards the levelling member the efforts that tend to separate the plate and the surface.
  • the first opening can be closed or, also, open in its lower part, defining two side legs in the second member.
  • the cladding plates and the levelling parts are disposed on the surface to clad, as explained above, said plates can be set on the adhering product using slight taps with a mallet and the wedge is inserted in the first opening until the working surface makes contact with the flange, lightly pressing with the hand or, if desired, with a tapping instrument, such as a hammer or mallet.
  • a tapping instrument such as a hammer or mallet.
  • the third member is disposed in the scale frame of the support corresponding with the height of the cladding plate.
  • the first member is placed so that the feet rest on the cladding plate, with the wedge inserted between the first legs and with the third member and the second pushing portion disposed on opposite sides with respect to the second flat member of the base.
  • the handle and the first gripping portion pivot the first portion with respect to the support, so that the second portion pushes the wedge against the flange, producing efforts tending to separate the second member and the surface to clad, which also causes the separation of the flat base and the cladding plate, which remains in levelled position.
  • the second member is tapped (for example with the foot) which, thanks to the notches, separates from the base, it being possible to discard the second member and the base being lost under the cladding plate, concealed once grout is applied to cover the joints. Shearing stress in the direction of the joint.
  • the parts of the device of the invention which, in service conditions, are designed to make contact with the cladding plates, are preferably manufactured in plastic materials, with less density and hardness than metal materials, so as not to damage the plates.
  • the device of the invention has a simple, light construction. It additionally allows, thanks to the combination of the pusher and the scale, an application of efforts which is repetitive, as well as adapted to the height of each cladding plate and does not depend on the uncontrollable application of force with the hand or a hammer.
