Abstract

The present invention relates to a baseplate for floors. More specifically, it is a baseplate for laying tile floors in outdoor environments.

Description

BASEPLATE FOR FLOORS

Specification

As is well known, the laying of flooring in outdoor areas usually involves the preparation of a rough subfloor on which, subsequently, the tiles are laid, spaced out at the desired distance from each other.

Spacers can be placed between the tiles before they are laid, so that the tiles are always placed at the same distance from each other.

This method does, however, have some drawbacks.

First of all, as illustrated, it requires several steps, resulting in the intervention of specialised operators.

Another problem with the known technique relates to the considerable amount of time it takes to lay a regular floor. Before each tile is laid, measurements of the distance between the tiles must be taken. In addition, great care must be taken when laying the tile on the floor, in order to respect the measured and desired distance between the various tiles.

Another known problem with the technique is the attachment of the tiles to the subfloor, which is not sufficiently stable.

In fact, over time, the tiles may shift and the size of the joints may change; as time passes, the floor becomes uneven.

In order to solve the above-mentioned problems, outdoor flooring pads have been introduced.

These pads are placed on the subfloor in a regular pattern and act as spacers between the tiles. Thanks to these baseplates, it is possible to position the tiles evenly and in a short time.

Such baseplates do, however, have problems.

First of all, different baseplates must be used depending on the desired joint width.

In addition, base plates according to the known technique do not allow the use of levelling devices.

Tiles, then, arranged with the known baseplates may not maintain their original position, as they are not solidly fixed to the baseplates.

It is an object of the present invention to provide a baseplate for floors which overcomes the problems of the known technique.

Another purpose of the invention is to provide a baseplate for floors that is flexible in its use.

A further scope of the invention is to provide a baseplate for floors which improves anchoring of the tiles to the substrate.

Still another purpose of the invention is to provide a baseplate for floors which facilitates the use of levelling devices.

These and other purposes are achieved by a baseplate for floors according to the appended claims.

The baseplate according to the invention is, therefore, dry-laid on a rough subfloor of the stabilised type without cement.

The distribution of the adhesive on the baseplate allows the four tiles to be joined to the baseplate and, consequently, to each other.

In turn, thanks to the attachment to the baseplate, the tiles are joined to each other, creating a kind of latticework. Further features and details can be better understood from the description that follows, given as a non-limiting example, as well as from the attached drawing tables, in which fig. 1 is an axonometric view from above of a baseplate for floors according to the invention; fig. 2 is an axonometric view of a part of figure 1 indicated with B; fig. 3 is an axonometric view from below of the baseplate of figure 1 ;

With reference to the appended figures, in particular figures 1 to 4, a baseplate for floors comprising a flat structure 12 of quadrangular shape with rounded comers is identified with 10.

Protruding upwards from the flat structure 12 is a cross-shaped structure 14 identifying four quadrangular portions 16 at the comers of the same flat structure 12.

In each of the four quadrangular portions 16, in particular on the upper face of the flat structure 12, nine circular relief elements 18 are identified.

Each raised element 18 is connected to the corresponding quadrangular portion 16 by means of four connecting portions 20, interspersed with each other by four openings 22.

In the lower face of the flat structure 12, in particular in each of the four quadrangular portions 16, there are nine cavities 23 in the shape of a four-leaf clover, obtained in correspondence with a corresponding circular element 18, as visible in figure 4.

In the centre of the cross-shaped structure 14, a cross-shaped aperture 24 is cut to accommodate a cross-shaped leveller as will be illustrated later.

Each arm of the cross-shaped structure 14 comprises an inner fin 26 and an outer fin 28 which both extend vertically.

Each inner fin 26 is arranged closer to the cross-shaped opening 24, while each outer fin 28 is arranged more peripherally to the centre of the flat structure 12.

Furthermore, the inner fins 26 are thinner than the outer fins 28.

The outer fins 28 are joined to the flat structure 12 by removable braces.

In each arm of the cross-shaped structure 14, a longitudinal aperture 30 is provided between the inner fin 26 and the outer fin 28 suitable for accommodating the base of a bridge leveller or a screw leveller.

The procedure for the use of the previously illustrated baseplate for floors 10 is described below.

First, a subfloor is created on which the baseplates 10 and, above them, the tiles can be placed. The thickness of the joints to be obtained is decided. In the event that a greater thickness is preferred, all the highs present on the baseplate 10 are left, i.e. both the inner flaps 26 and the outer flaps 28.

If, on the other hand, a reduced joint thickness is desired, all outer flaps 28 are removed from baseplate 10, leaving only inner flaps 26.

Once this choice has been made regarding the size of the joints, proceed by placing the baseplates 10 on the substrate in a regular and homogeneous manner.

Any levelling or spacer devices are then joined.

In fact, on each baseplate 10 can be coupled a central cross leveller 30, inserted in the cross opening 24, as illustrated in figure 6.

Alternatively, four bridge spacers 32 may be attached to each baseplate 10, each of which is inserted into the longitudinal opening 30, as illustrated in figure 8.

Alternatively, screw levelers 34 may be used, each of which is fixed to the baseplate 10 in a corresponding longitudinal opening 30, as illustrated in figure 10.

Once the levelling devices and/or spacers have been fixed, an adhesive C is distributed on the baseplate 10.

The circular relief elements 18, together with the passage openings 22, facilitate the adherence of the glue to the baseplate 10.

In fact, the glue C can pass through the openings 22 and disperse into the cavities 23.

In this way, the glue C is distributed both above and below the baseplate 10, allowing the bonding of the tiles P to the baseplate 10.

The paving operations then provide that, once the adhesive C is arranged on the baseplate 10, the tiles P are arranged.

Finally, we proceed by operating the levelling devices or spacers, in particular, the cross leveller 30 of figure 5, the four bridge spacers 32 of figure 7, or the four screw levellers 34 of figure 9.

In this way, the tiles P are made coplanar.

As can be seen from what has been described, the baseplate 10 according to the invention is therefore advantageous because it allows the tiles P to be joined together and to prevent them from moving against each other.

Thanks to the circular relief elements 18, the openings 22 and the cavities 23, the baseplate 10 allows an optimal distribution of the adhesive with a favourable adhesion of the tiles P to the baseplate 10 itself. Furthermore, the baseplate 10 according to the invention facilitates the regular arrangement and stable connection of any spacer and/or levelling devices to the substrate, by means of the baseplate 10 itself.

Variants and embodiments other than those illustrated above are possible and are to be considered within the scope of protection defined by the appended claims.
