项目背景

The project’s context

深创投广场于 2013 年启动，于 2022 年竣工，其总建筑面积为 167640 平方米，建筑高度为262米，位于深圳后海的核心区，与华润总部春笋比邻而立。

项目基地有三个特征：

1.边界——背靠办公商务区，面向深圳湾；

2.枢纽——地铁线、街道及二层步行系统穿越基地；

3.连接器——这是一个综合众多要素的联系体。

Shenzhen Capital Plaza was launched in 2013 and completed in 2022. The total construction area of the project is 167640 square meters and the building height is 262 meters. It is located in the core area of Houhai, Shenzhen, and stands next to the China Resources Headquarters. The project base has three characteristics. First of all, the project backs to the office and business district and faces Shenzhen Bay. Second, subway lines, streets, and two-story pedestrian systems across the base. Third, it is a link that integrates many elements. The location, scale, and transportation resources of the project determine that it is a "hub park" integrating commercial, hub, coastal activities, and other elements.

项目的区位、规模和交通资源决定了它是一个集商业、枢纽、滨海活动等要素于一体的“枢纽园区”。裙房联系了周边，漩涡般开放的体量将地铁、商业、步行系统、滨海活动、屋顶花园等要素组合在一起，成为一个“枢纽公园”。

The podium connects the surrounding, and the swirling open volume integrates the subway, Elements such as commerce, pedestrian system, waterfront activities, and roof gardens are combined to become a "Central Park".

设计理念

Design ideas

设计采用独特的折叠表皮形式体现了滨海建筑（波浪）和金融大厦（钻石），给大众以稳定、轻盈、优雅的形象。

通过研究形体，我们得到一个立面控制线，在这个基础上寻找到一个三角形基本单元，这个单元可以组合成钻石的形状，通过立体化的处理形成折叠的表皮。办公塔楼遵循高效实用的原则，在结构和空间的结合上采用一体化的创新设计，并全方位关注人的感受和体验，适度向城市开放。

The design uses a unique folded skin form to embody the coastal architecture (wave) and financial tower (diamond), giving the public an image of stability, lightness, and elegance. By studying the shape, we get a facade control line, and based on this line, we find a triangular basic unit, which can be combined into the shape of a diamond, and form a folded skin through three-dimensional processing. The tower follows the principle of high efficiency and practicality and adopts integrated innovative design on the combination of structure and space. At the same time, the project pays full attention to people's feelings and experiences and is moderately open to the city.

Shape generation

我们在方形塔楼的原规划体量上，首先将塔楼东西向延展到最大面宽，使得东侧的观海景观面最大化，为塔楼办公空间创造价值。在近地空间退让出南北向集散广场，塔冠南北方向变宽，东西向缩短，使得顶部的总部办公获得南侧的最佳景观与朝向。

On the originally planned volume of the square tower, we first extended the tower from east to west to the maximum width, maximizing the sea view on the east side and creating value for the office space of the tower. In the near ground space, retreat to the north-south distribution square, widen the tower crown in the north-south direction, and shorten it in the east-west direction, allowing the headquarters office at the top to obtain the best landscape and orientation on the south side.

结构体系

Structural system

外部结构框架采用钢结构菱形斜交网格，使得立面形式、结构体系和内部空间一体化；但斜交网格的节点受力以及施工复杂，因此，深入研究斜交网格的节点受力性能，实现斜交外框架结构的安全经济合理，以此达到完美的立面效果，才是整个项目的关键点。

The external structural frame adopts the steel structure rhombus oblique grid, which integrates the facade form, structural system, and internal space; however, the stress situation and construction method of the nodes of the oblique grid are very complicated. Therefore, it is the key point of the whole project to deeply study the node force performance of the oblique grid, to realize the safety, economic, and reasonableness of the oblique outer frame structure, and to achieve the perfect facade effect.

可呼吸式建筑表皮

Breathable epidermis

幕墙表皮采用隐藏式的开启扇，巧妙的解决了自然通风与自然排烟，降低过渡季节的能耗，实现了可呼吸式的建筑表皮。利用 800 毫米宽的装饰线条实现隐藏式开启，也排除了台风天的安全隐患，提高了整个项目的幕墙抗风安全级别。

The curtain wall skin adopts a concealed opening fan, which ingeniously solves the problem of natural ventilation and natural smoke exhaust, reduces energy consumption in the transition season, and realizes the breathable building skin. The 800mm wide decorative line is used to realize the concealed opening. It also eliminates the safety hazard in typhoon days and improves the wind resistance safety level of the curtain wall.

装饰线条遮挡玻璃

同时 800mm 的装饰线条遮挡玻璃，玻璃实际为梯形（最窄处满足三银夹胶 Low-E 中空玻璃大于 300mm 的最小加工尺寸），露出的完成面由三角形尖角玻璃交接，解决了尖角玻璃难以加工安装的难题，保证了原有塔楼折叠表皮的立面效果。

At the same time, 800mm decorative lines block the glass, which is actually trapezoidal (the narrowest part meets the minimum processing size of three silver adhesive Low-E hollow glass greater than 300mm). The exposed finished surface is connected by triangular pointed glass, solving the problem of difficult processing and installation of pointed glass, and ensuring the facade effect of the original tower folding skin.
