项目位于上海民生码头“八万吨筒仓艺术中心”一层空间，八万吨筒仓作为码头沿岸最具震撼力的工业遗产，前身是号称“亚洲最大容量”的散粮筒仓，当其原本的生产功能在城市发展中逐渐退去，留下的是因时代工业背景建造逻辑所呈现的宏伟构筑 – 倒锥形米漏+环形圈梁+环形对称柱网体系。米漏表皮呈斑驳的锈迹，述说着老上海的历史，锥体直径约10.6米，底部距地约5米。

aerial view to the “80,000-ton Silo Warehouse Art Center” of Shanghai Minsheng Wharf
The project is located on the 1st floor of the “80,000-ton Silo Warehouse Art Center” of Shanghai Minsheng Wharf. Once recognized as the largest bulk grain silo in Asia, the 80,000-ton Silo today has become the most stunning industrial heritage on Minsheng Wharf. As its original production functions gradually fade away, the grand construction marked by the features of the industrial era stands out. One of the most notable features is the combination of inverted cone-shaped funnel, ring-shaped beams and column grids. The old rusty funnel tells us a lot about the history of Shanghai. The diameter of the cone is 10.6 meters, while the distance from the cone’s bottom to the floor is about 5 meters.
The job of this project is to design the temporary exhibition stands for the “Good Life” – Yangtze River Delta Public Cultural Space Innovation Design Competition. The temporary exhibition stand will be set at 5 meters above the ground and below the funnels.

the combination of old and new construction systems creates a certain historic significance
Converse with Time
The industrial features presented by the inverted-cone-shaped funnels are quite dramatic to the eye. Besides, set against the ring-shaped beams, the many funnels arranged in particular patterns become a historic artifact to honor the past. Such a combination of geometric shapes, rustic looks and concrete beams creates a certain historic significance, where we find the soul behind this project, namely to converse with time.

To present it in visual form, a cone is designed to grow upward from the floor to respond to the inverted-cone of the funnel. We aim to connect the two with symmetrical relation of a geometric shape. In terms of structure, the symmetric orderliness created by the 14 circular steel tubes delivers a sharp contrast to the funnel structures in concrete, where a special spatial language is expressed through the differences between the present and past architectural systems – a great power from the universe to facilitate connection.

In construction we can see the art of connecting and merging. In this project of JPIII, the construction features are showed through the methods of hinging and installing, specifically using steel joints to realize modular assembly. As the exhibition industry usually requires fast set-up and easy dismantling and low cost, all the components are prefabricated and produced in the factory and pre-assembled, so that the only thing we need to do on the worksite is to set-up. The ways of joining components include high-strength bolt hinging and jointed board mortising. In this way, after we send the components to the worksite, only a few people were needed to get the set-up done. Such an arrangement demonstrates the concept applied by the Joints Pavilion Series: the product is a semi-manufactured product, while the design drawing can also be the installation instructions.

The cone structures are elevated by 15 centimeters, supported by 16# i steals scattering around a central point evenly. Rectangle square tube were laid between the beam grillages, and triangle enclosure structure helps steadying the layout. An opening is left at the entrance of the architectural installation for installing slopes later. 14 seamless circular steel tubes are braced to the sides of the cones, which is 4.5 meters tall. Prefabricated hinge components are used on the upper and lower positions to join with each other. Through these arrangements, the designer intends to create a triangle, the most stable geometric shape, as its main structure.

▼展陈主题：“美好生活”一词定义了内容的基调，Theme: “Good Life” defines the tone of the exhibition © Freeman
The theme of the exhibition is to showcase “Good Life” – the winning designs of Yangtze River Delta Public Cultural Space Innovation Design Competition. The term “Good Life” defines the tone of the exhibition. In that spirit, Roarc Renew wants to provide visitors with a relaxing place where the hustle and bustle is blocked out as much as possible, and dried flowers are used as a carrier for interpreting the “Good Life”. Roarc Renew connects 750 dried flowers of 36 kinds end to end with steel wires and arranges them in a symmetrical array on the outside of the supportive wall made from diagonal steel pipes. The flower bouquets are put in transparent acrylic pipes that are 30 cm in diameter and 4 meters in length and fixed by customized hardware hinges, forming 14 giant test tubes that seal the beauty of these dried flowers.

Due to the short duration of the exhibition, material recycling and sustainability have also become a focus of Roarc Renew. After selecting and comparing a variety of materials, flame-retardant corrugated cardboard is chosen as the content display board and floor paving. Corrugated cardboard has high strength – a 15mm thickness can withstand an average load of 6 tons per square meter. The cardboard is designed to be double-layered, which meets the ground bearing capacity demand on the one hand, and, on the other hand, solves the flatness issue of the 3.6-meter non-conventional display board. After many rounds of tests, the cardboard is the only material that can meet the three criteria: a thickness of only 3 cm, light weight in hanging, and non-bending. Furthermore, through CNC cutting, the accuracy tolerance of cardboard can be limited to within a millimeter. The corrugated cardboard has a unique cross-section that does not require any edge sealing treatment; plus, the exposed corrugated cardboard texture can better reflect a sense of spontaneous structure and the architecture style of JPIII.
After the event, JPIII will be moved to Kangqiao Town in Shanghai, as a shared space for the local citizens to use and enjoy. The use of joints for connection will be fully utilized to make it most convenient for quick dissemble and construction.

The steel structural components presented in JPIII have a stable order, to which the lighting design should be aligned to follow the overall structure, remaining hidden in the structure while highlighting the steel components. The core of illumination is to use light to create shadows, and the light and shadow are the key elements in this space. The illumination lighting is composed of three parts: 1, functional lighting, where the light source is hidden in the components for better exhibition display; 2, creative lighting, where a beam of downward light is hidden in the middle of an eight-hanging-panel display and the beam angle is controlled so that the light can pass through the layers of components and projects a shadow in the shape of a word 米 (rice), echoing the rice bin on the top as a stinger; 3, atmospheric lighting, where narrow-angle spotlights are used to project lights upwards to illuminate the dried flowers and form an overall atmosphere with ambient light.
