Description

Il presente modello di utilità riguarda i tubi flessibili in materiale plastico aventi una parete intermedia uniformemente corrugata o ondulata, una parete o camicia interna liscia ed una parete o camicia esterna The present utility model relates to flexible pipes in plastic material having a uniformly corrugated or corrugated intermediate wall, a smooth internal wall or jacket and an external wall or jacket.

Da precedenti domande di brevetto della stessa richiedente sono noti tubi flessìbili in materiale plastico con una parete ondulata aventi una camicia interna continua liscia ed una camicia esterna costituita da una pellicola protettiva riportata in materiale plastico Tale pellicola può essere posta o avvolta attorno alla parete ondulata per proteggere il tubo dai raggi ultravioletti e per impedire il deposito di sporcizia o la penetrazione di calcestruzzo o altro materiale nelle gole della parete ondulata aperte verso l’ esterno. From previous patent applications of the same applicant, flexible pipes in plastic material with a corrugated wall are known having a smooth continuous internal jacket and an external jacket consisting of a protective film inserted in plastic material. This film can be placed or wrapped around the corrugated wall to protect the pipe from ultraviolet rays and to prevent the deposit of dirt or the penetration of concrete or other material in the grooves of the corrugated wall open to the outside.

D’altra parte, è pure noto, ad esempio dalla pubblicazione di brevetto n° DE 297 06 044, un tubo in materiale plastico a tre pareti avente una parete interna liscia, una parete intermedia ondulata ed una parete esterna anch’essa liscia, dove le tre pareti vengono coestruse e si trovano collegate intimamente l’una con l’altra In altri termini, in un tale tubo, dove tutte le pareti sono sostanzialmente saldate tra loro, la parete più esterna non è rimovibile laddove occorra accedere alla parete ondulata del tubo, né la succitata pubblicazione insegna o suggerisce la possibilità di asportare la parete esterna On the other hand, it is also known, for example from patent publication no. the three walls are coextruded and are intimately connected to each other.In other words, in such a tube, where all the walls are substantially welded together, the outermost wall is not removable where it is necessary to access the corrugated wall of the tube, nor does the aforementioned publication teach or suggest the possibility of removing the external wall

Scopo del presente trovato è di fornire un tubo ondulato a tre pareti dove la parete esterna è estrusa insieme alla camicia interna e alla parete ondulata senza però esservi intimamente combinata per una sua agevole rimozione dove e quando necessario. The object of the present invention is to provide a three-walled corrugated tube where the external wall is extruded together with the internal jacket and the corrugated wall without however being intimately combined with it for its easy removal where and when necessary.

Lo scopo è raggiunto con un tubo a tre pareti del tipo succitato, dove la camicia esterna è in un materiale plastico non compatibile con quello della parete ondulata e quindi non saldabile con questo nel corso dell’estrusione Un esempio di realizzazione del trovato è qui di seguito descritto con riferimento all’allegato disegno, indicativo e non limitativo, che mostra una vista prospettica di una parte di tubo ondulato a tre strati The object is achieved with a three-walled tube of the aforementioned type, where the outer jacket is made of a plastic material that is not compatible with that of the corrugated wall and therefore cannot be welded therewith during the extrusion. described below with reference to the attached drawing, indicative and not limiting, which shows a perspective view of a part of three-layer corrugated pipe

Il tubo qui proposto comprende una parete o camicia interna liscia 11 , una parete intermedia uniformemente ondulata 12, recante cioè una successione di anse o gole 13 che si alternano con creste 13 ’, ed una parete o camicia esterna liscia 14 che ostruisce le gole della parete ondulata 12 rendendone quindi la superficie esterna continua. The tube proposed here comprises a smooth inner wall or jacket 11, a uniformly undulated intermediate wall 12, that is, bearing a succession of loops or grooves 13 which alternate with ridges 13 ', and a smooth outer wall or jacket 14 which obstructs the grooves of the corrugated wall 12 thus making its external surface continuous.

La camicia esterna 14 può essere coestrusa con la parete ondulata 12 e la camicia interna 1 1 In ogni caso, la camicia esterna è in un materiale plastico diverso dal, e non compatibile con il, materiale plastico formante la parete ondulata, cosi da non saldarsi con questa ma da aderirvi separabilmente. Il tubo risultante è quindi protetto dalla camicia esterna, ma può allora essere agevolmente spellato anche a tratti dove necessario per poter accedere ad ogni sua parte dall’esterno per vincolarvi componenti complementari o ausiliari, così come previsto in alcuni sistemi di assemblaggio, anche dopo che il tubo è stato posato in opera The external jacket 14 can be coextruded with the corrugated wall 12 and the internal jacket 11 In any case, the external jacket is made of a plastic material different from, and not compatible with, the plastic material forming the corrugated wall, so as not to weld. with this but to adhere to it separably. The resulting tube is therefore protected by the external jacket, but can then be easily stripped even in sections where necessary in order to access each of its parts from the outside to bind complementary or auxiliary components to it, as required in some assembly systems, even after the pipe has been laid on site
