A MOLDED RIDGE TILE MADE OF BITUMEN IMPREGNATED CELLULOSE, AND AN APPLICATION THEROF

摘要

PURPOSE: A molded ridge tile made of bitumen impregnated cellulose and an application thereof are provided to use members which are arranged between flanges with predetermined closed internal angles for various angle ranges of ridges. CONSTITUTION: A molded ridge tile (1) made of bitumen impregnated cellulose includes a linear and flat embossing strip (10) at the central concave part of a ridge tile to be extended along each flange (3). Pairs of ribs (11) are laterally arranged on the central part (2) of the ridge tile. The internal angles of the flanges are between 96° and 116° and a flange angle is between 32° and 42° about the horizontal line when no strain stress exists.
