Tunnel lining panel.n n n With a modular character that determines an assemblynfast, safe and efficient, the panel configures a kind ofnprismatic-rectangular bowl (1) based on sheet metalnmade of enameled and vitrified steel, in which it is establishednfirst a core (7) high, resistant to temperatures ofnup to 1260 ° C, then a series of ceramic separators (8),nbased on high density calcium silicate, and finally a corenlow (9) calcium silicate treated to minimize itsnhydrophilic and temperature resistant behavior of the order ofn1000ºC, fixing these elements to the bowl (1) bynorganic adhesives and by mechanical fixings (10). Thenside walls of the bowl are equipped with recesses (4)nfor coupling to cross bolts fixing thenpanels. In this way a highly resistant panel is achievednFire charges, easy to clean, resistant to both aggressionsnphysical as chemical, and with a high light reflection index,nwhich makes it especially suitable for tunnels. |
