BACKFLOW PREVENTION CAP FOR PANELS HAVING INTERLOCKING FOLDS

摘要

A backflow prevention cap for panels having interlocking folds, which prevents a backflow of water into seamed panels through fine gaps between the interlocking folds of the seamed panels by wind action. Each of panels has a tetragonal panel body (7), outer interlocking folds (9) provided by folding outwardly two neighboring sides of the panel body, and inner interlocking folds (11) provided by folding inwardly two remaining sides of the panel body. The backflow prevention cap includes a water shielding part (3) having a sheet-shaped wedge structure to be installed in the top ends of the outer interlocking folds (9) of each panel and supported in the top ends of the outer interlocking folds by a locking means when the panels are continuously seamed together through a fold-interlocking method.
