"SISTEMA MODULARE PER LA REALIZZAZIONE DEL SOTTOFONDO O MASSETTO DEL SOLAIO EDILIZIO" "MODULAR SYSTEM FOR THE CREATION OF THE SUBBASE OR SCREED OF THE BUILDING FLOOR"

DESCRIZIONE DESCRIPTION

A) Campo della tecnica a cui fa riferimento l?invenzione: A) Field of the technique to which the invention refers:

La parte del solaio denominata sottofondo o massetto nel settore delle costruzioni edili. The part of the floor called subbase or screed in the building construction sector.

B) Indicazione della tecnica preesistente: B) Indication of the pre-existing technique:

Come ? noto il sottofondo (o massetto) ? quello strato del solaio posato sulla soletta in CLS, cio? sull?estradosso del solaio, che ha come scopo ottenere una superficie orizzontale planale per la successiva posa dell?impianto di climatizzazione a piastra o pavimento radiante, oppure - in assenza di quest?ultimo -atto a ricevere la pavimentazione finita, tale strato include le guaine e tubazioni degli impianti tecnici (2d) e viene realizzato con una malta cio? un inerte e un legante miscelati con l?ausilio di acqua. How ? known the substrate (or screed) ? that layer of the floor laid on the concrete slab, the cio? on the extrados of the attic, which has the purpose of obtaining a flat horizontal surface for the subsequent installation of the plate or radiant floor conditioning system, or - in the absence of the latter - suitable for receiving the finished flooring, this layer includes the sheaths and pipes of the technical systems (2d) and is made with a mortar that is? an inert and a binder mixed with the aid of water.

Come ? noto lo stato della tecnica ? che il sottofondo sia sempre realizzato con questo procedimento, che comporta un conferimento presso il cantiere, e una movimentazione all?interno dello stesso, di importanti e pesanti volumi di materiale e un impiego di particolari attrezzature per la miscelazione, tutto questo ? associato a un gravoso consumo di acqua, e una complessit? di realizzazione per la quale devono intervenire maestranze specializzate che in quanto tali risultano marcatamente costose. How ? Do you know the state of the art? that the substrate is always made with this procedure, which involves a transfer to the construction site, and a handling within the same, of large and heavy volumes of material and the use of special equipment for mixing, all this? associated with heavy water consumption, and a complexity? of construction for which specialized workers must intervene and as such are markedly expensive.

Inoltre lo strato del sottofondo o massetto, per il peso dei materiali utilizzati, impone una maggiore portanza di tutta la struttura del piano del solaio generando indirettamente un ulteriore maggior costo del solaio stesso. Furthermore, the layer of the substrate or screed, due to the weight of the materials used, imposes a greater bearing capacity of the entire structure of the floor slab, indirectly generating a further higher cost of the floor itself.

C) Esposizione dell?invenzione e dei vantaggi apportati rispetto alla tecnica preesistente: C) Exposition of the invention and the advantages it brings compared to the pre-existing technique:

Lo scopo della presente invenzione ? di migliorare questo processo pur ottenendo un sottofondo o massetto con pari caratteristiche di quello realizzato col procedimento convenzionale, in particolare rendendone la posa pi? facile e rapida, meno costosa e con importante minore consumo di acqua cos? come di energia elettrica, sostituendo la maggior parte del volume dello strato, ottenuto solitamente con la malta, attraverso l?uso di due elementi (1a, 1b) prodotti industrialmente per stampaggio di materiale preferibilmente polistirenico o poliuretanico dunque molto leggero, con caratteristica di modularit? e la cui forma ? funzionale a inglobare gli impianti tecnici come tubazioni e guaine (2d) nelle parti vuote o cave e negli incavi (2a), impianti tecnici che risultano quindi compresi nello strato cos? ottenuto, e successivamente protetti da una malta oppure da materiale granulare a secco (2b), oppure da elementi accessori (2e). The purpose of the present invention ? to improve this process while obtaining a substrate or screed with the same characteristics as that created with the conventional procedure, in particular by making the installation more? easy and quick, less expensive and with important lower water consumption cos? as electricity, replacing most of the volume of the layer, usually obtained with mortar, through the use of two elements (1a, 1b) industrially produced by molding of material preferably polystyrene or polyurethane, therefore very light, with a modularity characteristic ? and whose shape? functional to incorporate the technical systems such as pipes and sheaths (2d) in the empty or hollow parts and in the recesses (2a), technical systems which are therefore included in the layer cos? obtained, and subsequently protected by a mortar or by dry granular material (2b), or by accessory elements (2e).

Con quanto descritto si ottiene una operativit? molto rapida, semplice e sistemica che non esige specializzazione ma invece maestranza generica con un abbattimento del costo della manodopera per la sua realizzazione, oltre a non necessitare di macchinari appositi o attrezzature dedicate. With what is described you get an operation? very rapid, simple and systemic that does not require specialization but instead generic workers with a reduction in the cost of labor for its realization, as well as not requiring special machinery or dedicated equipment.

Questo sistema si traduce in un miglioramento del processo di realizzazione del sottofondo o massetto caratterizzato da un considerevole risparmio di risorse e di tempo, e con conseguente abbattimento del costo per realizzarlo. This system translates into an improvement in the process of making the substrate or screed characterized by a considerable saving of resources and time, and with a consequent reduction in the cost of making it.

Claims

Patent application for Industrial Invention under the title: "MODULAR SYSTEM FOR THE CREATION OF THE SUBBASE OR SCREED OF THE BUILDING FLOOR" CLAIMS

1. Modular system for the creation of the substrate or screed suitable for being laid on the extrados layer of the building floor, and composed of a first element (1a) and a second element (1b) industrially made, preferably but not exclusively in polystyrene material or polyurethane characterized by:

- The elements (1a, 1b) be made with an industrial molding process or with an additive manufacturing process such as 3D printing or with any industrial serial process.

- Have overall form preferable almost? parallelepiped composed of having a preferably square or rectangular base and a first lower thickness (1c) and a second upper thickness (1d) perimetrically recessed with respect to the first lower thickness (1c) or instead not presenting this recess, and having in the second upper thickness (1d) recesses (2a) with a suitable shape suitable for containing pipes and sheaths of the technical systems (2d) or not presenting these recesses.

- Have an overall shape obtainable for single molding or for more? moldings of the first lower thickness (1c) and of the second upper thickness (1d) and in the second case present on the surfaces in contact with a mechanical joining system preferably by interlocking or instead having smooth surfaces suitable for joining with a gluing agent or by thermal fusion to lead back to the functional contextual form of the two elements (1a, 1b).

- Present both elements (1a, 1b) characteristic of modularity? therefore combining a multiplicity? of elements (1a, 1b) placed on the extrados of the floor or joined to it with a gluing agent, a flat horizontal surface of unlimited dimensions is created, while the horizontal juxtaposition of the elements (1a, 1b) can provide on the first lower thickness (1c) a mechanical or interlocking joint or instead not provide it.

2. According to claim 1, once the flat horizontal surface has been obtained by placing the elements (1a, 1b) together, the resulting empty or hollow parts and the recesses (2a) suitable for housing the sheaths and pipes of the technical systems (2d) will be filled with a mortar what? a mixture of inert and binder or with granular material then laid dry (2b), or closed with the accessory elements (2e) preferably made of polystyrene or polyurethane material or polymeric plastic, thus obtaining? a finished flat horizontal surface ready for the subsequent layers to be superimposed.

3. According to claims 1 and 2, the upper surface of the elements (1a, 1b) and of the accessory elements (2c) can present a special shape (2f) suitable for accommodating the flexible pipes of any radiant plate heating to be superimposed on the finished flat surface corresponding to the substrate or screed, or instead not present them.

4. According to claim 1, the elements (1a, 1b) have dimensions: if they have a square base shape, they vary from 30 to 100 cm in length and width, while if they have a rectangular base, they vary from 30 to 100 cm in width while the length will be ? twice the corresponding width, while the? total height sar? from 6 cm to 60 cm and specifically with the height of the first lower thickness (1c) varying from 2 cm to 20 cm and the height of the second upper thickness (1d) varying from 4 cm to 58 cm.

5. Process for making the finished flat horizontal surface of the substrate or screed according to the preceding claims:

- In phase 1 the elements (1a, 1b) are laid close to each other against the wall (4) chosen for the beginning of the installation and until they completely occupy the extrados of the floor, thus shaping the final elements (1a, 1b) when it reaches the wall opposite to that of the beginning of installation, both in length and in width.

- In phase 2, any pipes and sheaths of the technical systems (2d) are laid inside the empty or hollow parts between the elements (1a, 1b) and in the recesses (2a) of the second upper thickness (1d).

- In phase 3 the empty or hollow parts and recesses (2a) are filled or occluded as already? previously described bringing the upper level to the same share (at par) of the upper level of the elements (1a, 1b), there? both where the pipes and sheaths of the technical systems (2d) have been housed and where they are not foreseen.
