Abstract: Panel systems and installations thereof are provided wherein laterally opposite flanges of panel and flange means in the system form a gap with one another, and those flanges are adapted to be anchored to sub-structure, such as of a building, with the anchor means used for that purpose leading within the gap between the flanges and into grooves in the flanges which widen the gap locally between the flanges. Outer lateral ends of the anchored flanges are covered by cover means which engages engagable means of the panel and flange means.

Abstract: A conjoint facia, hood and water dam is provided having dam and first engagable means affording dam means with ridge structure, and first engagable means. Sheet roofing leading onto the dam means is clamped to the ridge structure by clamp means subsequently to be covered by a facia and hood member, the latter having hood structure and facia means with second engagable means extending from the facia means. The first and second engagable means together form restraining means to be engaged for maintaining the facia means horizontally laterally restrained and the first engagable means includes detaining means for detaining the facia and hood member against upward movement relatively to the dam and first engagable means with the restraining means being engaged.

Abstract: A coping structure is provided wherein a splice joint between a pair of normally inverted channel-like coping members is had through use of a splice member which cooperates inside the channels of the pair of coping members for covering a transverse seam between adjacent longitudinal ends of the coping members, the splice member .[.web furthermore being biased to seam covering position by resilient means interposed between the splice member web and the web of a saddle, the saddle having legs engaging legs of the pair of coping members and.]. being .Iadd.supported and biased upwardly to cover the seam, and front and rear legs of the coping members being engaged, against upward movement, with means .Iaddend.secured to a wall supporting the coping structure.
