Temporary structure, e.g. for hall, circus tent or hangar - has frame made from aluminium sections in buttressed arches and masts to take weight of upper section

摘要

The structure consists of a frame of aluminium sections forming arches (5) set at regular intervals and joined by horizontal beams to form a polygonal shape which rests on end buttresses (13) made from vertical (14) and angled (15) posts.A supporting cable (22) extends beneath the upper section (21) of the frame and has vertical stays (23,24,25) to distribute the load of the upper section between masts (34,35) situated in line with the arches and outside the zones enclosed by the vertical posts (14). The masts can form extensions of the vertical posts and can be made in one piece with them, equipped with couplings for the angled posts and the upper sections of the arches.The masts have guy lines (40) which can be connected to the ground adjacent to the feet of the angled posts (15). ADVANTAGE - More convenient to erect and dismantle, using frame components of reasonable size.
