LightPRO贝壳馆是一种轻质结构,它将由天然纤维生物复合材料型材制成的主动弯曲格子壳与拉伸膜相结合。由此产生的系统是两个双曲面的组合,共享一个连续的梁的轮廓。该轮廓由两个连接的型材组成,作为一个梁,将两个系统的力转移到连接到表层基础的三个锚点。

The LightPRO Shell Pavilion is a lightweight structure that combines an active-bending gridshell made of natural fibre biocomposite profiles with a tensile membrane. The resulting system is a combination of two doubly curved surfaces that share a continuous beam outline. The outline is composed of two connected profiles that act as a beam, transferring forces from both systems to three anchor points attached to a superficial foundation.

开发的 “竹子一样 “的天然纤维基生物复合材料型材是通过拉挤技术新生产的。拉挤技术是一种制造具有恒定截面的纤维增强聚合物的连续工艺。在这个项目中,使用了天然亚麻和大麻纤维。生产的型材是空心的,直径为25毫米,厚度为4毫米,长度从6.5米到12.5米不等,以适应所需的跨度。亭子的覆盖跨度为10米,周边的最大高度为4.8米。

The developed ‘bamboo-like’ natural fibre-based biocomposite profiles are newly produced through the pultrusion technique. Pultrusion is a continuous process for manufacturing fibre reinforced polymers with a constant cross-section. In this project, natural flax and hemp fibres were used. The produced profiles are hollow, with a diameter of 25mm and 4mm thickness and lengths ranging from 6.5m to 12.5m to fit the required span. The pavilion has a covering span of 10m and maximum height of 4.8m at the perimeter.

用钢缆的传统对角线绑扎方法来连接网格中的型材。网格通过一个定制的连接系统连接到梁的轮廓上。卷材被连接到三个基础上,并使用绳索系带沿周边张紧。

Traditional diagonal lashing methods with steel cables are used to join the profiles in a grid. The grid is connected to the beam outline via a customized joint system. The membrane is attached to the three foundations and tensioned along the perimeter using rope lacing.

这个创新的结构展示了对未来建筑的可持续性方法。该成果是基于几年来在生物基材料应用领域的研究。
材料的开发和生产是由DITF、CG-TEC和BAM的合作伙伴进行的。Zenvision GmbH参与了技术设计和开发阶段的工作。Steinhuder公司协助评估了该结构的另一种生物基连接系统。Bieri公司生产并赞助了该薄膜。

This innovative structure is demonstrating a sustainability approach towards future architecture. The outcome is based on several years of research in the field of biobased materials application.
Material development and production were carried out by the partners from DITF, CG-TEC, and BAM. Zenvision GmbH was involved in the technical design and development phases. Steinhuder assisted in assessing an alternative bio-based connection system of the structure. Bieri produced and sponsored the membrane.
