ROUND ROOFING MATERIAL FOR DESCENDING CORNER RIDGE
Document Type and Number:
Japanese Patent JP3164226
Kind Code:
B2
Abstract:
PURPOSE: To deal with variation of roof slope by means of one kind of round roofing material for a descending corner ridge.
CONSTITUTION: A nearly half pyramid-like round roofing material A for mutually connecting roof materials of step roofing form on a descending corner ridge, is formed so that the vertical section of a decorative plane may correspond to the butt end form of the decorative plane of the roof material. A folding back piece 5 bent on the decorative face side and a locking tongue piece 2 formed by projecting the center part of the folding back piece are formed on the upper part, and a step difference decorative plane 4 bent on the back side and an engaging tongue piece 6 bending the extreme end of the step difference decorative plane 4 on the back side in nearly parallel with the decorative face are formed on the lower part. Further, fitting tongue pieces 7 formed by bending the right and left end edges of the decorative plane on the back side are formed, and hence the round roofing material A for the descending corner ridge is formed. Consequently, it can deal with variation of roof slope only by changing the length of the locking tongue piece 2.
