<P>PROBLEM TO BE SOLVED: To provide a structure of an external drainage slope face 1 with a slope plate 9 made of a synthetic resin foam as a substrate 5, the external drainage slope face 1 enhancing heat resistance with a minimum cost increase and reliably suppresses deformation due to heat, even adjacent to a window 12 with a double-glazed glass 13 which reflects the sunlight to cause temperature rise. <P>SOLUTION: A parallel plate 10 with parallel top and bottom faces made from a synthetic resin foam having a higher thermal deformation temperature than other lower layer components of the substrate 5 is overlapped on the uppermost part of the substrate 5 along a slope face 11 of the slope plate 9 at a slant. Heat resistance is thereby imparted to the substrate 5 without using a synthetic resin foam having a high thermal deformation temperature to constitute the slope plate 9 itself. <P>COPYRIGHT: (C)2012,JPO&INPIT |
