RIQUALIFICAZIONE DI CONDOTTA DI VENTILAZIONE EI120 ORIZZONTALE E

VERTICALE CON FLEXBIFIRE sp.40mm

Riqualificazione antincendio con grado di protezione EI120 di condotta di ventilazione metallica

orizzontale e verticale con feltro a base di fibre minerali ed alcaline non biopersistenti rivestito da

speciale tessuto di vetro denominato FLEXBIFIRE avente spessore nominale di sp.40mm.

PRODOTTO: FLEXBIFIRE sp.40mm singolo strato

CONDOTTA: Condotta metallica di classe A o superiore (EN 1507), in posizione verticale o

orizzontale, con o senza diramazioni laterali, superiori o inferiori

POSA:

- tratti rettilinei: Avvolgere il condotto con singolo strato di FLEXBIFIRE 40mm,

sovrapposizione trasversale di 200mm, sovrapposizione longitudinale di 200mm per tutto

lo spessore del FLEXBIFIRE. Occorrerà aiutarsi con il nastro Bifire per far aderire bene il

FLEXBIFIRE al condotto metallico, e poi fissare il tutto con il filo d’acciaio;

- tratti curvilinei: Avvolgere il condotto con singolo strato di FLEXBIFIRE 40mm partendo

dal raggio esterno della curva procedendo verso l’interno. Nella parte interna della curva

occorrerà concentrare e compattare il FLEXBIFIRE per i raggi più piccoli; se necessario, si

dovrà posare un secondo materassino al fine di non lasciare nessuna parte del condotto

metallico scoperta; si dovrà comunque garantire una sovrapposizione trasversale e

longitudinale di 200mm; Occorrerà aiutarsi con il nastro Bifire per far aderire bene il

FLEXBIFIRE al condotto metallico, e poi fissare il tutto con il filo d’acciaio.

FISSAGGIO PRODOTTO: 1 giro di filo d’acciaio, diametro 1.2mm, passo 333mm

SOSTEGNO CONDOTTA: il sostegno in orizzontale deve essere opportunamente dimensionato in

funzione del peso al metro lineare del condotto e del carico sui pendini di sospensione (EN 1366-1

punto 13.6.1). Indicativamente, per una condotta avente sezione 1000x500x1,0 utilizzare pendini

in acciaio φ10mm, barra orizzontale a “C” 40x30x2 preforata, passo 1.6mt.

In verticale vincolare il condotto nella zona dell’attraversamento a soletta con sostegno in profili

ad L 75x50x5 e barre filettate di serraggio.
