Definitions

  • the present invention relates to a support device for a raised floor, particularly for outdoors.
  • Raised outdoor floors are known, often used in the building sector to create a floor with different types of finish and an underlying cavity used for the outflow of rainwater and also for the passage of pipes of various kinds.
  • These known raised floors are made by arranging a plurality of support devices on the upper surface of a support surface, possibly waterproofed, flat or suitably inclined of a surface to be paved. Tiles or floor plank support profiles can then be laid on these support devices.
  • the known support devices generally comprise a support base for the surface, on which the raised floor must be formed, an externally threaded tubular sleeve, which can be screwed into a corresponding internally threaded cylindrical cavity provided in the support base, and a head which can be removably connected to the upper end of the threaded sleeve and intended to receive in support or constraint, depending on the type of raised floor to be created, the floor tiles or the sections of a joist substructure supporting the slats of a floor.
  • the head and the threaded sleeve of each support device in two distinct parts, to be removably coupled together when making the raised floor according to the type of this .
  • a known support device of this type is described for example in EP 3425134 .
  • the current technique first provides for coupling, by means of the threaded sleeve, the head of each device support to the relative base during the formation of the raised floor, and then to rotate the threaded sleeve with respect to the head, which remains fixed as it is linked to the tiles already laid or to the support profiles of the staves, to adjust the distance between the head and the base of the support device and therefore the flatness of the floor being formed.
  • this rotation can be carried out by introducing a special key through the joints between the tiles, at their vertices, which engages a corresponding cavity, provided at the upper end of the threaded sleeve, and then making the sleeve itself rotate to thus vary the height of the head with respect to the base.
  • the aim of the invention is to eliminate these drawbacks and to propose a support device for raised floors, which allows to adjust the flatness of the floor, which does not require the use of a key and which therefore does not involve the limitations highlighted by this.
  • Another object of the invention is to eliminate these drawbacks while keeping the head of the support device separate from the threaded sleeve in order to be able to use the same threaded sleeve and base assembly with different heads interchangeably constrainable to it, and therefore to contain the number of the different support devices to keep in stock for use with different types of raised floors.
  • Another object of the invention is to create a support device which can also be used to create raised floors in the event of imperfect flatness of the underlying support surface.
  • Another object of the invention is to propose a support device which allows to obtain all these advantages without substantially increasing the costs for its production.
  • Figures 1 - 5 show a support device according to the invention in a first embodiment, which can be defined as having a "fixed" head and which is configured for the constraint of tiles.
  • a base 2 a threaded sleeve 4 and a head 6, all preferably made of thermoplastic material, in particular polypropylene.
  • the base 2 comprises a flat circular plate 8, intended to rest on a support surface of the raised floor to be created, which in this case is formed by quadrangular tiles, for example made of ceramic material.
  • a cylindrical collar 10 rises upwards, which is monolithic with the flat circular plate, is stabilized in its position by a plurality of stiffening radial baffles 12 and is internally threaded.
  • the threaded sleeve 4 consists of a cylindrical tubular element presenting on its external surface a thread configured to interact with the internal thread of the collar 10.
  • the threaded sleeve 4 is closed at the top by a disc 14, located in a slightly recessed position downwards with respect to the edge of the sleeve itself and presents a cylindrical relief 16 centrally positioned.
  • Equiangular radial appendages 22 branch outwards from the lateral surface of this cylindrical relief 16, which in the example illustrated are four ( fig. 7 ), even if their number could be different but preferably not less than three. They have a limited thickness which allows them to have a certain flexibility on the vertical plane.
  • the head 6 of the device according to the invention consists of a disc with a generally annular shape, whose upper surface presents elements interacting with the components of the floor placed above it and constituted, in the embodiment illustrated, by tiles 24 ( fig. 4 ). More particularly, these elements consist of small flat vertical appendages 26, arranged radially on two mutually perpendicular vertical planes, and have the function of defining the correct position of four tiles 24, which rest with their corner portion on the head 6 and more particularly, with two of their orthogonal edges, they rest on two spacers 26, also disposed to each other on two orthogonal vertical planes.
  • the spacers 26 define with their position the correct reciprocal position of the tiles 24 and with their thickness the correct width of the joints, which must be created between the tiles 24.
  • the illustrated embodiment is intended for the creation of a raised floor formed by rectangular or square tiles.
  • the invention also provides support devices for tiles of other shapes, to which spacers 26 obviously correspond in different number and arrangement. For example, if the floor is to be formed with hexagonal tiles, each head will be provided with three spacers arranged at 120° to each other.
  • An annular flange 30 extends inwards from the internal circular edge of the head 6 ( fig. 6 ), slightly depressed with respect to the surface of the head itself and presenting four radial openings 32, arranged at 90° to each other and having slightly larger dimensions to the plan dimensions of the appendages 22 of the cylindrical relief 16.
  • Two teeth 34 are provided on the sides of each opening 32, which on the side of the opening 32 show an inclined side, while on the opposite side they show a vertical side, i.e. perpendicular to the surface of the annular flange 30.
  • the various support devices can advantageously be prepared beforehand for laying, in the sense that a head 6 is applied to each threaded sleeve 4 having the spacers 26 corresponding to the width of the joints to be created between adjacent tiles 24.
  • the assembly provides that the relief 16 of the closing disc 14 of a threaded sleeve 4 is introduced into the central opening of each head 6 so that the appendages 22 of the cylindrical relief 16 of the sleeve pass through the openings 32 of the annular flange 30 of the head 6.
  • the head 6 is made to rotate in one direction in the other with respect to the threaded sleeve 4 to an extent sufficient to allow the appendages 22 to be made to slide along the inclined plane of the respective teeth 34 and yield elastically to bending to then snap into place between two adjacent teeth, which in this way prevent the rotation of the head 6 with respect to the threaded sleeve 4, when this is screwed to the base 2.
  • the devices thus arranged are then positioned with the base 2 in the correct position on the support surface of the raised floor and on the head 6 of all these the individual tiles 24 are then placed so that each of these rests with the corners on the head 6 of four devices and that each head 6 rests on the corners of four tiles 24, spaced apart to the extent defined by the spacers 26.
  • the installer acts on the base 2 and rotates it in one or the other direction, depending on whether the head 6, which is locked in rotation with respect to the threaded sleeve 4 and holds it locked in rotation when the base 2 rotates, is lowered or raised to the desired amount.
  • the radial stiffening baffles 12 also advantageously perform the function of gripping elements of the base 2 for its rotations.
  • the invention provides for having different heads 6 provided with spacers 26 of different thicknesses, so as to be able to choose and use for the particular floor to be made the heads with spacers thickness corresponding to the width of the joints to be obtained.
  • a different head 6' is applied to the threaded sleeve 4 of each device, presenting protrusions 36 for engaging a profile 38 forming with other sections called joist substructure.
  • the head 6' presents four pairs of protrusions 36 arranged so as to allow two by two to snap into engagement according to two arrangements rotated 90° to each other a profile 38 at two different intermediate points of its two lateral edges, as illustrated in fig. 9 , or two aligned sections which rest against it with one of their ends.
  • the head 6" is provided with a single protrusion 39 which develops linearly and presents holes for the passage of screws 40 intended to constrain a profile 38' for engagement at one of its edges, as illustrated in fig. 11 .
  • the fundamental difference between the traditional support devices and the support device according to the invention is that while in the former, the adjustment of the flatness of the floor requires the rotation of the threaded sleeve 4, i.e. an operation which is performed with different methods depending on the type of raised floor to be created and in some cases it is not even possible during the laying of the floor, in the second case the adjustment of the flatness of the floor always takes place with the same methods and that is by rotating the base 2, regardless of the type of raised floor to be created, and it is always possible during the laying of the floor.
  • the embodiment illustrated in figures 12,13 instead of being definable with a "fixed” head, can be defined as a "self-leveling" head, as it allows the head 6 to be able to obtain perfect flatness of the raised floor even in the case of the underlying slab, to which the raised floor rests by means of the support devices according to the invention, which have slopes or irregularities.
  • the lower flat surface of the head 6 does not rest rigidly on the upper edge of the threaded sleeve 4, but is provided with an annular relief 42 with a concave (or convex) profile shaped like a spherical segment, cooperating with a counter-shaped profile present in an annular relief 44 provided on the closing disc 14 of the threaded sleeve 4.
  • the self-leveling head can also be configured to create raised floors with tiles, i.e. be provided with spacers 26, or to create floors with a joist substructure and finish with staves, i.e. be provided with protrusions 36, 39 for the constraint of profiles 38, 38' to support the slats.
