The 2019 Beijing international horticultural expo is the largest A1 horticultural expo ever, with 110 countries and international organizations, as well as more than 120 non-official participants, including 31 provinces and municipalities in China, Hong Kong, Macao and Taiwan. Shanghai Qin Sen garden co., LTD. (hereinafter referred to as “Qin Sen garden”) as a enterprises exhibitors originality creating Qin Sen pavilion, designed to fully exert industrial chain advantage, the enterprise in the international stage of ecological landscape, Chinese style garden, living state protection of traditional Chinese architecture practice result, make extensive and profound Chinese civilization won the world respect, make Chinese cultural heritage with renewed fresh vitality. Qinsen enterprise pavilion is located in the northwest of the exhibition area, with a total length of 78 meters and a total width of 30 meters. The pavilion covers an area of 2,324 square meters. The main road of the exhibition area is located on the north side of the exhibition area. The west side is adjacent to the belt green axis, and the east side is the rest square, located between the China pavilion and the plant pavilion.

秦森企业展园以独特的设计理念—“木刨花”，在设计上，利用生态纽带从空间维度上把整个展园有机联系起来，深入践行“曲面参数化技术应用+立体绿化”等多种技术手段，设计出国内大型竹木构筑。从前期简单概念，到中期形态空间定形，再到后期赋予“生命”，借木刨花简单纯粹的寓意和舒展优美的形态，用更加丰富而夸张的超前想法表现出来。每个月的活动日，我们在构筑下面举办“木雕木艺”体验活动，让游客与构筑物达到互动。

With the unique design concept of “wood shavings”, Qinsen enterprise exhibition garden organically connects the whole exhibition garden from the spatial dimension by using ecological ties, deeply practices various technical means such as “application of surface parameterization technology + three-dimensional greening”, and designs domestic large-scale bamboo and wood constructions. From the simple concept in the early stage, to the shape space in the middle stage, and then to the later stage to give “life”, the simple and pure implication of wood shavings and the beautiful shape of stretching, expressed with more rich and exaggerated ideas in advance. Every month on the activity day, we hold “wood carving and wood art” experience activity under the building, so that visitors can interact with the building.

为了实现建筑的空间形态的要求，结合工程竹的材料受拉强和抗剪弱的特点，结构设计采用了双层曲面网格的异形双曲面空间工程竹结构。关于内外拱连接部分，由于累计误差造成最后连接处有50MM误差，保证曲面的完整性和流畅感。由于构筑整体为多面异形，单体空间形态向外倾倒，内外拱双层网格受力实现内拱受压，外拱受拉，充分发挥工程竹结构适合轴向受力的特点。内外拱在顶部采用多点连接形式，而非采用传统内外拱结构的内拱与檩条的垂直连接，这样做的最大好处是避免了结构的横纹受拉，而是通过特殊的节点设计将横纹受拉转换为顺纹受拉，更好的利用材料，多点连接增加了结构的连接可靠性。因为构筑为多维空间立体，呈现多面扭曲，所以每一根杆件的尺寸与偏转角度方向都不同，竹木杆件与五金件的槽口衔接要精准无误，给构筑设计增加很大难度，最后采取对每根杆件和五金件独立编号，在杆件加工和搭建上要有百分百的专业和细心。

In order to achieve the requirements of the building’s spatial form, combining the characteristics of strong tensile strength and weak shear strength of the engineering bamboo material, the structure design adopts the special-shaped hyperboloid spatial engineering bamboo structure with double curved mesh. As for the connection part of the inner and outer arch, there is a 50MM error at the final connection due to the accumulated error, ensuring the integrity of the surface and the sense of fluency. As the construction of the whole is multi-faceted and irregular, the monomer spatial form tilts outwards, the internal and external arch is stressed by the double-layer grid, and the external arch is stretched, giving full play to the characteristics of engineering bamboo structure suitable for axial stress. Arch at the top with multipoint connection, both inside and outside rather than inside and outside the traditional arch structure of the arch and purline vertical connection, the biggest advantage is to avoid the structure of the horizontal stripes in tension, but rather through a special node design converts horizontal stripes tension to shun wen tensile, better use of materials, multipoint connection increases the connection reliability of structure. For constructing multi-dimensional three-dimensional, presents the multifaceted distortion, so that every member of different size and direction of the deflection Angle, bamboo bar and hardware notch to connect to accurate, adds great difficulty to build design, finally take of each bar and hardware independent number, on the bar processing and build to have hundred professional and careful.

项目总结：“木刨花”构筑利用竹子生长优势，以竹子为材料，运用螺栓五金件固定，构成整体骨架，并且所有的弧“拱”是独立单体，加上屋顶覆盖垂直绿化（佛甲草），可在不同场地按照不同功能需求，反复拆卸组装，展馆淋漓尽致地体现出秦森公司精明务实的生态、环保、节能理念。
Project summary: “wood shavings” building use bamboo growth advantage, with bamboo as material, using the fixed bolt hardware, constitute the overall frame, and all of the arc arch is independent monomer, vertical greening and roof (Buddha a grass), can be in different area according to the different functional requirements, and remove the assembly, the pavilion incisively and vividly reflects Qin Sen company dynamic pragmatic ecological, environmental protection, energy saving ideas.
