Under-roof drainage device

摘要

An under-roof drainage device for draining moisture condensation on the undersurface of a roof or ceiling. The device comprises a plurality of elongated unit panels each having a longitudinal central portion dividing the unit panel into a pair of panel sections with opposite free edges, the panel sections each being sloped downwardly from the central portion toward the free edge. A male half member extends downwardly from the free edge of the panel section. There are also provided a plurality of gutter means each having the same length as the unit panel and including a female member formed centrally on and extending along the gutter means. The adjacent unit panels provide mated male half members detachably interfitting with the female member on the gutter means. The assembled device is mounted beneath a roof, or used as a ceiling with the gutter means inclined relative to the horizontal for the drainage.
