CONTINUOUS DOUBLE OR QUADRUPLE GLAZED LIGHTING DEVICE

摘要

1. Continuous double or quadruple skin weathertight glazing in which the sheets (1) are in honeycomb-structure extruded plastic material, in which the integration of part of the structure of the glazing sheets is achieved by means of the notching of the two opposite edges of each sheet over the whole length of a skin wall parallel to the lines of the structure and over a limited width approximately equal for each sheet in such a way as to form longitudinal toothings (38 and 39), followed by the interlocking of these toothings (38 and 39), characterized by the fact that the glazing sheets (1) are cold-formed, their solid junction being ensured by a fixing comprising at least one upper or lower stiffening rib, these sheets in addition bearing on an inclined plane of the trimmer plates (11) located on the structural roof opening, a commercial L-shaped member (20) covering the edges of the sheets over the whole of the two parallel lengths of the glazing and being fixed to the trimmers (11) in such a way that the edge of the said sheets is joined solidly to the said L-shaped member (20) and the said inclined plane of the trimmers (11).
