Glazed structures

A glazed structure comprising semi-rigid glazing panels of plastic material arranged within the structure with longitudinal edges of pairs of adjacent panels in side-by-side relation and each longitudinal edge including an integral upstanding lip, each pair of adjacent panels within the structure being supported at their adjacent longitudinal edges by an outwardly facing surface of a longitudinally-extending support bar whereby the two adjacent edges of the two panels are supported by that bar along their entire length, the bar including a retaining flange parallel to the said surface of the bar but spaced outwardly therefrom with the two lips being located between the retaining flange and said surface, and a connector channel applied over the retaining flange and the outer sides of the two lips to retain the lips between the retaining flange and the said surface of the bar and thereby to secure the edges of the two adjacent panels to the bar.

A glazed structure comprising bars which provide structural support arranged in parallel relation, semi-rigid glazing panels arranged within the structure with longitudinal edges of pairs of adjacent panels being supported by a said bar which is common to both panels and which extends lengthwise of the two panels, each of the adjacent panel edges having an upstanding lip and the bar including an integral T-section extension from a panel-support surface of the bar, with the upstanding lips of the two panels lying between the support surface and the transverse flange of the T-section extension at respective sides of the central flange of the T-section extension, and a connector applied over the projecting lips to hold the lips captive within the T-section extension and thereby to secure the longitudinal edges of the panels to the bar.

A glazed structure having semi-rigid glazing panels of plastic material carried by support bars which extend longitudinally of the panels such that respective said bars support adjacent longitudinal edges of adjacent panels, each bar being of hollow cross-section with an integral T-section extension, and the extension reinforcing the bar against bending and also co-operating with a system for coupling the adjacent longitudinal edges of the adjacent panels to the bar in a weathertight manner.
