Description
Erected with different coloured coveringsalong the main routes of the Expo site and in front of the German Pavilion, the canopies create a sense of continuity and identity. The simple construction consists of four double-curved cotton-fabric membranes spanned between steel sections and tensioned after assembly by the main beams. Tension and compression rods stabilize the structure against wind suction and pressure. The main beams also function as gutters that channel rainwater into drainpipes in the central columns. The canopies are 7,5 x 7,5 m on plan and can be linked to form a continous covering. Polycarbonate sheets over the joints prevent the penetration of rainwater. The canopies are demountable and can be reused.
