Gravity-defying staircase by Close to Bone climbs up into the sky

由专筑网Yumi，韩平编译

由Close to Bone建筑事务所设计的这座耐候钢楼梯屹立在Flanders的一座小山上，它也成为俯瞰起伏的农田和Kabouterbos森林美景的瞭望台。

This weathering steel staircase by engineering studio Close to Bone cantilevers off a hill in Flanders, forming an observation tower overlooking rolling farmland and the Kabouterbos forest.

楼梯无支撑地矗立着，几乎有11.5米高，“漂浮”在Tielt-Winge自治市风景如画的基地上。

该建筑被称为Vlooyberg塔，比利时工作室设计它是为了取代基地上现存的木岗楼，该岗楼已经被破坏者烧毁。

Standing unsupported at almost 11.5 metres tall, the staircase "floats" above its picturesque setting in the theTielt-Winge municipality.
The structure known as Vlooyberg Tower was designed by the Belgian studio to replace an existing wooden lookout post on the site, which was burnt by vandals.

为了防止更糟糕的纵火行为，新塔完全使用金属材料。它由几部分镀锌钢材组成，镀锌钢外部包裹着预生锈的金属，也称为耐候钢。

“Tielt阶梯塔的故事可以追溯到很久以前。许多年前，从这座山到Vlooiberg的西边，用一个高约四米的木质瞭望塔装饰，”Close to Bone阐述。

To prevent further acts of arson, the new tower is engineered completely from metal. It comprises several galvanised steel sections that are clad in sheets of pre-rusted metal, known as weathering steel.
"The story of the Tielt stairway tower goes back a long way. For many years, the hill to the west of the Vlooiberg was adorned by a wooden lookout tower about four meters in height," explained Close to Bone.

“早期Tielt塔的设计暂且不提，不幸的是这座塔也吸引了破坏者，他们在塔上放火，彻底地毁坏了它，”Close to Bone继续说道。

“激烈的争论之后，市政府最终决定用新的、不朽的物体取代小木塔，希望能够经得起时间的考验。”

"Aside from the all the youth of Tielt, unfortunately this tower also attracted vandals who irreparably damaged it by setting it on fire," it continued.
"Heated debates followed, and the municipality finally decided to replace the small wooden tower with a new, monumental object that would be able to withstand the ravages of time."

耐候钢已成为地标性建筑广泛采用的材料，因为它锈迹斑斑的外表契合自然环境。在靠近鹿特丹的草原顶端，NEXT事务所设计了一个弯曲的生锈的钢走道，同时RintalaEggertsson事务所用这种材料设计了挪威河流上的通道。Vlooyberg塔生锈的橘红色参照了在该地区发现的红褐色的铁矿石的颜色。

Weathering steel has become a popular material choice for landmark architecture, as its aged appearance fits in well in natural settings. NEXT Architects designed a curling rusting steel walkway for a grassy peak in near Rotterdam, while RintalaEggertsson Architects used the material for ariver crossing in Norway.
The rusty orange colouring of Vlooyberg Tower is a reference to the red-brown ironstone found in the region.

观景台在阶梯的顶端，距地面约10米，高高的栏杆架上有微小的观察孔，田园风光一览无余。

A viewing platform is set 10 metres above the ground at the summit of the staircase, where small peepholes in the tall balustrades frame views over the pastoral landscape.

该塔重达12吨，根据工程师的说法，它是在“与自己的重量对抗”，工程师手动计算了施加在阶梯每一个元素上的力，并定义了它的形式和尺寸。

栏杆作为结构梁架，使楼梯保持直立，同时两个减震器有助于减轻脚下台阶的震动。整个结构是预制的，并在基地上用半天来安装。

Weighing in at 12 tonnes, the tower is at "war against its own weight" according to the engineers, who manually calculated the forces acting in each element of the staircase to define its form and dimensions.
The railings serve as structural beams to keep the staircase upright, while two dampers help to prevent the staircase from vibrating under foot. The whole structure was prefabricated and assembled on site over the course of half a day.

“作为一个具有强烈象征性意义的地标建筑，Vlooyberg塔名副其实，它象征性地提升了Tielt-Winge周围的美丽风景区的形象，”团队说。

"As a landmark with strong iconic value, the Vlooyberg Tower literally and figuratively raises the profile of the beautiful region around Tielt-Winge," said the team.
