Low tension strip for disconnected slanted roofs, has central region with flexural rigidity and boundary region that is provided as region of low tension strip

摘要

The low tension strip (22,38) has a central region (31,43) with a flexural rigidity (C) and a boundary region (29,30,44,45). The boundary region is a region of the low tension strip. The boundary region has another flexural rigidity (A,B) that deviates opposite to the central region.
