Traditional origami structures can be continuously deformed back to a flat sheet of paper, while traditional kirigami requires glue or seams in order to maintain its rigidity. In the former, nontrivial geometry can be created through overfolding paper, while in the latter, the paper topology is modified. Here we propose a hybrid approach that relies on overlapped flaps that create in-plane compression resulting in the formation of polyhedra composed of freely supported plates. Not only are these structures self-locking, but they have colossal load-to-weight ratios of order $10^4$.

传统的折纸结构可以连续变形回平坦的纸张，而传统的折纸需要胶水或接缝以保持其刚性。在前者中，可以通过折叠纸张来创建非平凡的几何图形，而在后者中，可以修改纸张拓扑。在这里，我们提出了一种混合方法，该方法依靠重叠的襟翼产生平面内压缩，从而形成由自由支撑板组成的多面体。这些结构不仅是自锁的，而且具有巨大的载荷重量比$\mathrm{1个}{0}^4$。
