Footbridge over the River Segre Ravetllat Ribas Architects

架构师提供的文本描述。这座人行桥只想成为塞格里河两岸之间的一条桥梁,在那里它跨越了利伊达市。这座新的人行桥更多地被理解为一个行程,而不是一个待在其中的地方。这座新的人行桥毫不掩饰被悬挂在河床上一个很高的高度的感觉。这种想法导致了一个调整尺寸,使行人和自行车交通与服务车辆的交通兼容。这样,整个河宽的过河就用两根柱子解决了,没有其他支撑。
Text description provided by the architects. The footbridge seeks only to be a link between the two banks of the river Segre where it crosses the city of Lleida. Understood more as an itinerary than as a place in which to remain, the new footbridge at no time pretends to erase the perception of being suspended at a great height over the riverbed. This thought has led to an adjusted dimensioning that make compatible pedestrian and bicycle traffic with that of service vehicles. In this way, the crossing of the entire width of the river is solved with two single pillars and no other support.
 
在每一个边缘的着陆是非常不同的。在右边,行人天桥支座力求避免环境的任何重大改变,而边幅则上升,以吸收因保存水压段而造成的高度差异。相比之下,在左岸,埃利斯难民营和河岸的新墙之间的空隙使得大桥的登陆范围得以扩大,这座桥可以无缝延伸,成为人行桥。桥的这一部分,扩大成扇子的形状,变成一个地方,邀请用户留下来观看历史城市,由拉苏加冕。同时,它提供了一个阴暗的角落在河公园。这里的目的是消除人行桥和城市之间的界限,在坚实的地面上延伸城市元素-铺路、长凳、长廊-伴随着沿河边缘的树木的出现,通过同样的穿孔,光线可以穿透桥的下部。
The landings are very different on each one of the margins. On the right side, the footbridge support seeks to avoid any substantial alterations in the surroundings, and the margin rises in order to absorb the height difference caused by preserving the hydraulic section. In contrast, on the left bank, the void existing between Avinguda dels Camps Elisis and the new wall of the riverbank allows to develop a wider landing of the bridge, which extends seamlessly and becomes the footbridge. This sector of the bridge, widened in the shape of a fan, is transformed into a place that invites the user to remain and watch the historic city, crowned by La Seu. At the same time it offers a shady corner over the river park. The aim here is to erase the limits between the footbridge and the city, extending the urban elements on firm ground –paving, benches, pergolas– accompanied by the appearance of trees that follow the edge of the river, through the same perforations that allow light to penetrate to the lower part of the bridge.
 
该人行桥的结构力求与这些设计意图相一致,并试图提供一个没有视觉障碍的平台,在那里,城市和河流的轮廓走上舞台。两根钢箱梁布置在不同的水平上,采用由相同材料和混凝土板制成的横梁加劲,允许将表面理解为具有Z截面的结构套件。这有助于减少总边缘的挑战桥接83米的中心跨度。板比下梁高出1,15米,减少了两米边缘的视觉效果。
The structure of the footbridge seeks to be consistent with these design intentions, and is attempted to offer a platform free of visual obstacles, where the profiles of the city and the river take the stage. Two steel box beams arranged on different levels, stiffened by means of transversal beams made from the same material and a concrete slab, permit understanding the surface as a structural suite with a Z-section. This helps to reduce the total edge in the challenge of bridging the eighty-three meters of the central span. The slab overhangs the lower beam by 1,15 metres and reduces the visual effect of the two-meter edge.
 
这个Z段有两种不同的高度和两种连接周围环境的方式.在朝南的一侧,楼板悬垂在较低的梁上,并由玻璃栏杆加冕,支撑着拉苏和这座历史名城的景色。在另一边,顶部梁充当一个不透明的栏杆,构成桥梁的高度。
This Z-section features two different elevations and two ways of linking up with the surroundings. In the south-facing side, the slab overhangs the lower beam and is crowned by a glass balustrade, supporting the vistas over La Seu and the historic city. In the opposite side, the top beam acts as an opaque balustrade and constitutes the elevation of the bridge.
