折板屋顶候车亭：钢板折叠出的结构

Design a bus shelter whose structure comes entirely from folding a flat plane. Show a roof formed as a series of deep zigzag folds running the shelter's length — a folded plate that needs no beams because the geometry itself carries the span — its creases sharp and its valleys draining naturally to one end. Detail the fold depth as generous, perhaps 300 millimetres, so the profile reads dramatically from the side as a row of triangles. Show the same folding logic continuing down one end wall, the plane turning through ninety degrees without a joint. Detail the material as a single thickness of steel plate, powder-coated in a deep colour — a bottle green or an oxide red — with the crease lines catching light along their length. Show the supports as two slim columns only, since the folding does the structural work. Detail a simple bench of timber slats beneath. Show hard sunlight so the folds throw a strong sawtooth shadow pattern. Photorealistic, geometric, saturated colour, low three-quarter view.
