在意大利撒丁岛Tempio Pausania的主广场上，这件别具一格的装置作品于近日开展，并以此献给意大利著名的歌唱家及作曲家Fabrizio De André。彩帆飘扬在小镇中心的上空。而这一不断变化的轻盈的装置由Alvisi Kirimoto + Partners根据Renzo Piano的最初构想设计而成。

A unique installation in the main square in Tempio Pausania, Sardinia, was inaugurated recently. It is dedicated to Italian singer-songwriter Fabrizio De André. A series of colored sails fluctuate in the sky, in the center of this small town. The light and ever-changing installation is designed by Alvisi Kirimoto + Partners together with Renzo Piano, who conceived the early idea.

建筑师Massimo Alvisi谈论道，这一轻盈而别具野性及生命力的装置，可以重新连接居民与小城的中心；起源于Renzo Piano“捕捉每一束光和它的颜色”的想法，而我们将这一系列装置置于广场上空，使得路人不得不向屋顶上方望去，也由此超越了这个区域本身的边角与限制，将建筑与天空的颜色作为新的背景。

“This intervention, with its lightness and its untamed vitality, allowed us to relate ourselves once again with small urban centers. Starting from Renzo Piano’s idea to ‘capture the rays of light and its colors’, we moved the action up high, above the piazza, thus forcing passers-by to look beyond the roofs, to deal with the gray buildings and the color of the sky, to transcend the angular margins of the area,” says architect Massimo Alvisi.

沿着小径走向这个仅有375平方米的小广场，可以看到由缆绳和帆构成的装置在展开时彩帆呈现出大小不一的三角形，闭合时则消失成为许多悬挂在建筑之间的“彩色铅笔”。

Narrow roads lead to the 375 square-meter piazza. The installation consists in a series of cables and sails. When open, the sails are triangular in shape and have varied dimensions; when closed, they disappear leaving space to a series of “colored pencils” suspended between the buildings.

12片三角形的彩帆各自有着不同的尺寸。最小的帆的三边是1.6米、1.2米和1.3米，面积为2.06平方米；最大的帆的三边是5.9米、4.5米、3.2米，面积为15.6平方米；采用印色的聚酯纤维作为材料。

The sails are 12 fabric triangles of different dimensions. The smallest one measures 1,60 x 1,20 x 1,30 (2,06 square meters), the largest one measures 5,90 x 4,50 x 3,20 (15,60 square meters). The fabric is printed polyster (Serge Ferrarì – Soltis 92).

每一片帆都装有电动滚轴、小棒、滑轮和校准用的弹簧。这些元件与航海船帆的构造也非常相似。被重新排列成独立或成组的彩帆，构成最终实现的这一造型。放置在曾经的市场大楼之中的一块面板控制这些彩帆的运动。控制板包含风力计和湿度计，可以在风力或雨量过大的情况下自动收帆。

Each sail is equipped with a motorized roller, rods, pulleys and a release spring that calibrate movements. The components are very similar to the ones employed for sailing. The sails may be rearranged in groups or individually, according to the final configuration one wishes to achieve. Their movement is controlled from a panel positioned inside the former-market building. Such control panel is provided with a wind gauge and a moisture meter that may trigger the automatic closing of the sails in case of excessive wind or rain.

形成网状的钢缆固定在被扎穿的厚而坚实的花岗岩墙壁上，水泥封堵住这些孔洞，同时也支撑着钢缆以减少视觉影响。

The net of steel cables is anchored to the thick and solid granite walls that were punctured, cement injected into the holes and holding the supports for the cables whose visual impact is hence minimal.

围绕着四栋外围建筑中除市场大楼的三栋的金属杆支撑着照明设备，总共包含根据距离彩帆距离而有着光学设置不同的14盏灯。用来支撑照明灯具的金属杆同时也支撑着用于特别表演或者多媒体装置的音响设备和投影仪器。

Along 3 of the 4 perimeter buildings (all except the market building) are metal bars that support the lighting fixtures. It’s a total of 14 lamps (iGuzzini – Maxi Woody) with different optics depending on their proximity to the sail. The metal bars that support the lighting fixtures are meant to also hold sound speakers and video projectors in case of special performances or multimedia installations.
