树叶教育步道

下载所需积分: 2

Gerecse 山丘的树冠步道融入了环境中，几乎在森林中消失了，只有在近距离检查时才能看到其圆形轮廓。在树木周围和之间，在大自然的中心，通过工程和工业结构连接两个村庄并跨越一条溪流，一个完美的几何构件出现了。几乎水平的环形系统内径为 44 米，倾斜度为 9%，由高 1-11 米的 30 厘米直径的钢柱支撑，这些柱略微倾斜，但垂直于路面。支撑结构的每个部分都是裸露的：柱子上有环绕横梁，横梁上有圆环片段，进而支撑着步道本身的金属结构，步道由橡木铺板和栏杆网格组成。步道几乎悬浮在空中的稳定性是由拉紧的钢丝提供的，这些钢丝在中间相遇于一个钢环，而其侧向运动则由支柱减震。实际上，这条步道也向我们展示了静力学的一课：它几乎完全屏蔽了物理力量的隐藏相互作用，同时展示了如何在空中建造一条树冠步道，尽管其钢结构的尺寸很大，但显得轻盈。

The canopy trail of the Gerecse Hills nestles into its environment, almost disappearing in the forest, and its circle-shape is only outlined on closer inspection. Around and among the trees, in the heart of nature, a perfect geometrical component appears by means of engineering and industrial structures linking two villages together and bridging a stream. Almost horizontal, the ring system with an inner diameter of 44 metres and an inclination of 9% is supported by 1-11 metre high steel pillars of 30-centimetre diametres that are slightly tilted, but perpendicular to the pavement. Each part of the struts is exposed: the pillars hold wrap-around beams with circle segments that in turn support the metal structure holding the trail itself which is made up of oak pavement planks and a lattice of handrails. The stability of the avenue seemingly floating is provided by the straining wires that meet in the middle in a steel ring, whilst its sideway movements are dampened by poles. This trail actually gives us a lesson of statics too: it almost entirely screens the hidden inter- play of physical forces, whilst showing how to build a foliage trail in the air which appears light-weight in spite of the dimensions of its steel structure.
