Description
La presente invenzione si riferisce ad un procedimento per la fabbricazine di un serramento, quale una finestra o una porta finestra, ed al serramento ottenuto mediante tale procedimento. The present invention relates to a method for manufacturing a window or door, such as a window or a French window, and to the window obtained by means of this method.
Come é ben noto agli esperti in questo particolare ramo della tecnica, esistono in commercio serramenti di legno, di metallo e di materia plastica. As is well known to those skilled in the art in this field, wooden, metal and plastic frames are commercially available.
Il telaio ed il controtelaio di un serramento di legno vengono ottenuti lavorando alla macchina untensile un massello, in modo da ottenre il profilato desiderato. Il profilato può essere unito con altri uguali per formare il telaio o il controtelaio rettangolare del serramento, che verranno poi verniciati, oppure ad esso, prima dell'assemblaggio, può essere applicata una impiallacciatura destinata a conferire al serramento finito un certo pregio. The frame and counterframe of a wooden window frame are obtained by working a solid block on the machine, so as to obtain the desired profile. The profile can be joined with other identical ones to form the frame or the rectangular counterframe of the window frame, which will then be painted, or a veneer designed to give the finished frame a certain value can be applied to it before assembly.
Il telaio ed il controtelaio di un serramento di metallo vengono ottenuti assemblando profilati metallici cavi, i quali possono essere già anodizzati o zincati, oppure anche verniciati dopo il montaggio. The frame and counterframe of a metal frame are obtained by assembling hollow metal profiles, which can already be anodized or galvanized, or even painted after assembly.
Il telaio ed il controtelaio di un serramento di materia plastica vengono ottenuti mediante assemblaggio di profilati estrusi cavi, che sono generalmente irrobustiti dall'introduzione in essi di un profilato metallico di irrigidimento. The frame and the counterframe of a plastic frame are obtained by assembling hollow extruded profiles, which are generally strengthened by the introduction of a stiffening metal profile in them.
Appare quindi evidente come il telaio ed il controtelaio di un serramento debbano soddisfare precise esigenze di robustezza e di finitura esteriore. It therefore appears evident that the frame and the counterframe of a window or door must satisfy specific requirements for strength and external finish.
Lo sforzo di tutti i costruttori di serramenti é evidentemente quello di cercare di soddisfare le esigenze predette al minor prezzo possibile. The effort of all window manufacturers is obviously to try to satisfy the aforementioned needs at the lowest possible price.
Tuttavia, i risultati ottenuti sono stati finora non completamente soddisfacenti per la sempre più alta incidenza della mano d'opera e per il crescente costo della materia prima impiegata. However, the results obtained so far have not been completely satisfactory due to the ever higher incidence of the workforce and the growing cost of the raw material used.
Scopo della presente invenzione é quello di realizzare un procedimento per la fabbricazione di un serramento, quale una finestra o una porta finestra, che sia attuabile con il minimo impiego di mano d'opera, utilizzando materiali estremamente economici, ottenendo nel contempo un prodotto finito molto robusto e esteticamente valido. The object of the present invention is to provide a process for the manufacture of a window or door, such as a window or a French window, which can be implemented with the minimum use of labor, using extremely inexpensive materials, while obtaining at the same time a very finished product robust and aesthetically sound.
A tale scopo, secondo la presente invenzione si é pensato di realizzare un procedimento per la fabbricazione di un serramento, quale una finestra o una porta-finestra, caratterizzato dal fatto di comprendere le seguenti passi: For this purpose, according to the present invention, it has been thought of realizing a method for the manufacture of a window or door, such as a window or a French window, characterized in that it comprises the following steps:
a) realizzare due semigusci, che insieme individuano la sagoma del telaio o controtelaio del serramento, mediante stampaggio di rispettivi pannelli di fibra di legno della lunghezza desiderata, su di una faccia di almeno un primo dei quali é applicato un foglio di un materiale decorativo, il semiguscio con il foglio decorativo comprendendo le pareti in vista del telaio del serramento, mentre l'altro semiguscio comprende le pareti in vista del telaio e pareti destinate a sovrapporsi internamente a pareti corrispondenti del semiguscio; a) creating two half-shells, which together identify the shape of the frame or counterframe of the window frame, by molding respective panels of wood fiber of the desired length, on a face of at least one first of which a sheet of a decorative material is applied, the half-shell with the decorative sheet comprising the exposed walls of the frame of the window frame, while the other half-shell comprises the exposed walls of the frame and walls intended to overlap internally with corresponding walls of the half-shell;
b) bagnare le superfici interne dei due semigusci con un solvente; b) wet the internal surfaces of the two half-shells with a solvent;
c) applicare a dette superfici bagnate di solvente uno strato superficiale di granuli di una materia plastica pre-espansa; c) applying a surface layer of granules of a pre-expanded plastic material to said solvent-wet surfaces;
d) accoppiare i due semigusci così da individuare un profilato avente la sagoma completa del telaio o controtelaio del serramento; d) coupling the two half-shells so as to identify a profile having the complete shape of the frame or counterframe of the window;
e) assemblare quattro profilati ottenuti come sopra descritto nella forma di un telaio o controtelaio di serramento; ed f) iniettare ed espandere all'interno di detto telaio o controtelaio una materia plastica iniettabile ed espandibile. e) assembling four profiles obtained as described above in the form of a frame or window frame; and f) injecting and expanding into said frame or counterframe an injectable and expandable plastic material.
Preferibilmente, uno dei semigusci viene stampato con un canale adatto a ricevere una guarnizione di tenuta in posizione opposta alla tradizionale battuta presente in un telaio o controtelaio di serramento, in detto canale essendo inoltre prevista una serie di fori per l'iniezione della materia plastica espandibile. Preferably, one of the half-shells is molded with a channel suitable for receiving a sealing gasket in a position opposite to the traditional stop present in a frame or frame counter frame, in said channel a series of holes are also provided for the injection of the expandable plastic material .
Preferibilmente, detti granuli pre-espansi e detta materia plastica iniettata ed espansa all'interno del telaio o controtelaio comprendono polistirolo. Preferably, said pre-expanded granules and said injected and expanded plastic material inside the frame or counterframe comprise polystyrene.
In successive operazioni al telaio può essere applicato un vetro, le cerniere, la chiusura con maniglia, le guarnizioni perimetrali, per cui é ottenuta un'anta di serramento che viene montata su di un controtelaio anch'esso munito di cerniere e guarnizioni perimetrali. In subsequent operations, a glass, the hinges, the handle closure, the perimeter seals can be applied to the frame, for which a door is obtained which is mounted on a counterframe also equipped with hinges and perimeter seals.
Ulteriori vantaggi del procedimento secondo l'invenzione saranno ancora più chiaramente compresi dalla descrizione esemplificativa seguente riferita ai disegni allegati, nei quali: Further advantages of the process according to the invention will be even more clearly understood from the following exemplary description referring to the attached drawings, in which:

Con riferimento alla fig. 1 dei disegni, con 10 e 11 sono rispettivamente indicati due semigusci i quali, assemblati, individuano il profilato 12 di fig. 2 che viene impiegato per la fabbricazione del serramento. With reference to fig. 1 of the drawings, 10 and 11 respectively indicate two half-shells which, assembled, identify the profile 12 of fig. 2 which is used for the manufacture of the window frame.
Il semiguscio 10 viene realizzato a partire da un pannello piano 13 di fibra di legno, ad esempio quella nota in commercio con il nome di FAESITE, che viene prima immerso in acqua calda e poi stampato, sempre a caldo, nella sagoma di fig. 1. Prima dello stampaggio a caldo, su di una faccia del pannello 13 é applicato un foglio 14 di un materiale decorativo impregnato di un adesivo a base di resine termoindurenti, che esplica la sua azione di incollaggio attraverso l'applicazione del calore durante la fase di stampaggio. Il foglio decorativo 14 può ad esempio essere una carta decorativa, oppure una impiallacciatura di legno; l'adesivo può ad esempio essere una resina melami-nica o ureica. The half-shell 10 is made from a flat panel 13 of wood fiber, for example the one known on the market with the name FAESITE, which is first immersed in hot water and then molded, always hot, in the shape of fig. 1. Before hot molding, a sheet 14 of a decorative material impregnated with a thermosetting resin-based adhesive is applied on one face of the panel 13, which performs its gluing action by applying heat during the phase. molding. The decorative sheet 14 can for example be a decorative paper, or a wood veneer; the adhesive may for example be a melamine or urea resin.
Il semiguscio 10 viene stampato nella sagoma comprendente le pareti del telaio del serramento destinate a risultare in vista, cioè in pratica tutte le pareti tranne quelle che verranno coperte dal vetro e dal relativo fermavetro. Inoltre, in una parete del semiguscio 10 é ricavato un canale 15 destinato a ricevere una guarnizione di tenuta, nel quale canale é praticata una serie di fori 16, il cui scopo risulterà evidente in seguito. The half-shell 10 is molded in the shape comprising the walls of the frame of the window frame intended to be visible, i.e. in practice all the walls except those that will be covered by the glass and the relative glass stop. Furthermore, a channel 15 is formed in a wall of the half-shell 10 intended to receive a sealing gasket, in which a series of holes 16 is made in the channel, the purpose of which will become apparent later.
Analogamente al semiguscio 10, il semiguscio 11 viene realizzato mediante stampaggio a caldo di un pannello 17 di fibra di legno anch'esso precedentemente bagnato in acqua calda, ma che però può non essere nobilitato dall'applicazione di un foglio di rivestimento. La sagoma del semiguscio 11, infatti, comprende le pareti non in vista del serramento e pareti destinate a sovrapporsi internamente alle pareti corrispondenti del semiguscio 10. Nella realizzazione di un controtelaio, invece, anche il semiguscio 11 viene nobilitato. Similarly to the half-shell 10, the half-shell 11 is made by hot molding a panel 17 of wood fiber also previously bathed in hot water, but which however may not be ennobled by the application of a coating sheet. The shape of the half-shell 11, in fact, includes the walls that are not in view of the window and walls intended to overlap internally with the corresponding walls of the half-shell 10. In the construction of a counterframe, on the other hand, also the half-shell 11 is ennobled.
I semigusci 10 e 11, stampati separatamente, vengono prima spruzzati sulle superfici interne con un solvente, e sulle stesse superfici viene poi deposto uno strato 19 di granuli pre-espansi. Per conseguenza, uno strato superficiale 19 di granuli di polistirolo pre-espanso (fig. 3) rimane intimamente attaccato alle superfici interne del profilato 12 per via dell'azione del solvente che li scioglie parzialmente così da incollarli al profilato medesimo. The half-shells 10 and 11, molded separately, are first sprayed on the internal surfaces with a solvent, and a layer 19 of pre-expanded granules is then deposited on the same surfaces. Consequently, a surface layer 19 of pre-expanded polystyrene granules (fig. 3) remains intimately attached to the internal surfaces of the profile 12 due to the action of the solvent which dissolves them partially so as to glue them to the profile itself.
I semigusci 10 e 11 stampati separatamente nella lunghezza desiderata vengono assemblati come mostrato nella fig. 2 dei disegni, così da individuare un profilato 12 avente una sagoma completa di un telaio (o controtelaio) di un serramento. L'assemblaggio viene realizzato per infilamento reciproco dei semigusci che può essere assiale o laterale; in quest'ultimo caso l'accoppiamento é reso possibile sfruttando la relativa elasticità dei semigusci, per cui il semiguscio 11 può essere introdotto attraverso la zona aperta del semiguscio 10. Prima dell'acoppiamen-to le superfici dei due semigusci destinate a venire in reciproco contatto sono spalmate di adesivo. The half-shells 10 and 11 molded separately in the desired length are assembled as shown in fig. 2 of the drawings, so as to identify a section 12 having a complete shape of a frame (or counterframe) of a frame. The assembly is carried out by mutual insertion of the half-shells which can be axial or lateral; in the latter case, the coupling is made possible by exploiting the relative elasticity of the half-shells, so that the half-shell 11 can be introduced through the open area of the half-shell 10. Before coupling, the surfaces of the two half-shells destined to come to each other contact are coated with adhesive.
II profilato 12 si presenta quindi già esternamente finito nelle pareti che risulteranno in vista e richiede solo una eventuale operazione di stuccatura in corrispondenza dei bordi liberi sovrapposti dei due semigusci. The profile 12 is therefore already externally finished in the walls which will be visible and requires only a possible grouting operation at the overlapping free edges of the two half-shells.

A questo proposito é da notare che il solvente, potendo evaporare, per via degli interstizi fra un granulo e l'altro e della relativamente grande camera d'aria all'interno del profilato scioglie solo parzialmente i granuli medesimi, che possono così individuare lo strato 19 predetto adatto per ricevere un riempitivo di polistirolo espanso iniettato direttamente, come verrà successivamente spiegato. In this regard it should be noted that the solvent, being able to evaporate, due to the interstices between one granule and the other and the relatively large air chamber inside the profile, only partially dissolves the granules themselves, which can thus identify the layer 19 predicted suitable for receiving a directly injected expanded polystyrene filler, as will be explained later.
Quattro profilati 12 stampati e preparati come sopra descritto, nelle misure desiderate, vengono assemblati come mostrato in Fig. 4 in modo da individuare un telaio (o controtelaio) 20 di serramento. L'assemblaggio può ad esempio essere realizzato mediante squadrette 21 inserite ed incollate entro le estremità dei profilati. Le squadrette 21 possono essere composte di legno massiccio, oppure comprendere un'anima metallica rivestita di materiale espanso ad alta densità, od essere di qualsiasi tipo adatto. Four profiles 12 molded and prepared as described above, in the desired sizes, are assembled as shown in Fig. 4 so as to identify a window frame (or counterframe) 20. For example, the assembly can be carried out by means of brackets 21 inserted and glued within the ends of the profiles. The brackets 21 can be made of solid wood, or comprise a metal core covered with high density foam material, or be of any suitable type.
Il telaio così ottenuto viene riempito di polistirolo espanso 22 (fig. 5) iniettato mediante ugelli schematizzati in 23 (fig. 4) che vengono introdotti attraverso i fori 16 predisposti nel semiguscio 10. Il polistirolo iniettato si espande e si vincola intimamente allo strato superficiale 19, chimicamente compatibile, in precedenza preparato per riceverlo. The frame thus obtained is filled with expanded polystyrene 22 (fig. 5) injected through nozzles schematized in 23 (fig. 4) which are introduced through the holes 16 arranged in the half-shell 10. The injected polystyrene expands and binds intimately to the surface layer 19, chemically compatible, previously prepared to receive it.
È inoltre da notare che il polistirolo iniettato in pressione comprime le pareti del semiguscio 11 contro quelle del semiguscio 10, le quali pareti si incollano fortemente fra loro, per cui il profilato 12 si comporta come una struttura monolitica. It should also be noted that the polystyrene injected under pressure compresses the walls of the half-shell 11 against those of the half-shell 10, which walls stick together strongly, so that the profile 12 behaves like a monolithic structure.
È in aggiunta ottenuto un vincolo stabile e duraturo fra il polistirolo e la fibra di legno, non ottenibile iniettando il polistirolo direttamente sulle superfici interne di profilato cosparse di solvente. Infatti, l'iniezione diretta del polistirolo sul solvente non permetterebbe a questo di evaporare abbastanza rapidamente, per cui il solvente stesso ha tempo di intaccare irreparabilmente specialmente gli strati superficiali del polistirolo impedendogli così di attaccarsi alle superfici interne del profilato di fibre di legno e di esplicare la sua funzione di elemento di irrigidimento delle pareti del profilato stesso. In addition, a stable and long-lasting bond between polystyrene and wood fiber is obtained, which cannot be obtained by injecting polystyrene directly onto the internal surfaces of the profile sprinkled with solvent. In fact, the direct injection of polystyrene onto the solvent would not allow it to evaporate quickly enough, so the solvent itself has time to irreparably affect especially the surface layers of the polystyrene thus preventing it from sticking to the internal surfaces of the wood fiber profile and perform its function as a stiffening element on the walls of the profile itself.
Nella Fig. 6, che mostra, a titolo di esempio un serramento finito realizzato secondo il procedimento dell'invenzione, il telaio é indicato con 24 ed il controtelaio con 25. Al telaio un vetro 26 é applicato tramite un usuale fermavetro 27 e guarnizioni di tenuta elasticamente cedevoli 28 sono incollate entro i canali 15, così da ottenere una anta di serramento. In Fig. 6, which shows, by way of example, a finished frame made according to the process of the invention, the frame is indicated with 24 and the counterframe with 25. To the frame a glass 26 is applied by means of a usual glass stop 27 and gaskets of elastically yielding seals 28 are glued within the channels 15, so as to obtain a window shutter.
Le cerniere 29 del serramento e la chiusura (non mostrata per semplicità di disegno) vengono vantaggiosamente applicate in corrispondenza delle pareti sovrapposte dei semigusci 10, 11, opportunamente predisposte anche per quello scopo, le quali hanno uno spessore adeguato. The hinges 29 of the window frame and the closure (not shown for simplicity of drawing) are advantageously applied in correspondence with the overlapping walls of the half-shells 10, 11, suitably arranged also for that purpose, which have an adequate thickness.
È in questo modo conseguito lo scopo menzionato di realizzare un procedimento mediante il quale sia possibile construire un serramento con un minimo impiego di mano d'opera ed utilizzando materiali estremamente economici, come fibra di legno e polistirolo espanso, rispetto a quelli tradizionalmente impiegati. È nel contempo ottenuto un serramento con adeguate caratteristiche fisicomeccaniche. In this way, the aforementioned aim of achieving a method by which it is possible to construct a window and door with a minimum use of labor and using extremely inexpensive materials, such as wood fiber and expanded polystyrene, with respect to those traditionally used is achieved. At the same time, a window with adequate physical and mechanical characteristics is obtained.
