Arched type barn roof structure - comprises rectangular cap sections arched in one direction fitting in supporting troughs on walls

摘要

The roof structure is particularly for barns, garages, shelters etc. It is built up of rectangular cap-type sections (1, 2, 3), arched in one direction, and trough sections (21-26). The trough sections which act as guttering are supported on the building walls forming the roof opening, and support the cap sections, which are secured to them. One type of cap section can be arched in one direction, ending in vertical edges extending vertically downwards, while in the other direction it ends in flanges or other suitable devices for fitting against an adjacent one. The second type has edges extending vertically downwards on three sides, with a flange etc. on the fourth side.
