The Burj Khalifa in Dubai is located in Dubai, United Arab Emirates. China State Construction Industrial, a subsidiary of China Construction Group, undertook the curtain wall project, mainly including the design, production and installation of unitized glass curtain wall and aluminum panel system. Recently, during his visit to Saudi Arabia and the UAE, the Chief Executive of the Hong Kong Special Administrative Region, Lee Ka-chao, took this project as an example to show the design, management and construction capabilities of Hong Kong's construction industry to the UAE.

China State Construction and Construction has always attached importance to and made good use of innovation, the primary driving force for development, and continued to increase technological innovation to lead the global curtain wall industry into the digital age. Guided by national strategic needs and industrial upgrading needs, technology empowers high-tech Quality development helps China Construction Group to accelerate its progress towards a world-class enterprise.

Over the years, Far East Curtain Wall Co., Ltd., a subsidiary of China State Construction and Development Co., Ltd., as the flagship brand of a state-owned enterprise that has been deeply involved in the field of high-end curtain walls for more than 50 years, has refined its unique design and development, manufacturing and engineering management advantages in the full international market competition, and has accumulated A large amount of experience in curtain wall engineering construction, covering various types of buildings, has undertaken curtain wall projects for world-renowned landmarks such as the Burj Khalifa, the tallest building in the world, the tallest Costanella Center Building in South America, and the Murray Road Curtain Wall Project in Central Hong Kong. It shines all over the world, decorating the city skyline, and with its unique charm and transparent texture, it builds the beauty of curtain walls and releases architectural value.

Burj Khalifa

As a landmark building in Dubai, the design of the Y-shaped floor of the Burj Khalifa is inspired by the desert flower spider orchid, which maximizes the integrity of the structure and allows people to enjoy the fascinating landscape of the Arabian Gulf. For the builders, behind the spectacular and beautiful Burj Khalifa are the huge challenges brought about by super wind pressure, extreme high temperature weather and deformation of super high-rise buildings.

The technical team optimized the glass configuration through innovative curtain wall system design and repeated thermal simulation calculations. In the cable-net double-layer curtain wall system, the vertical stainless steel shape design, intelligent control of metal sun visors, and research on hot aisle airflow were used to meet the thermal limit of the curtain wall. Requirements, to form a high-temperature-resistant solution for super-high-rise building curtain walls in hot environments; conduct research on wind pressure distribution, wind environment, and wind climate according to the 50-year wind force standard, and carry out more than 40 wind tunnel tests in succession. Design the corresponding curtain wall unit plate to enhance the stability of the unit plate, and use the aircraft head to simulate the wind force in the wind pressure test, adopt the shape of the curtain wall that meets the aerodynamic calculation standard, and avoid the formation of strong wind vortex at high altitude; the original research and development has a large-scale three-dimensional Adjust the curtain wall connectors to achieve a wide range of adjustments in three directions to ensure that the curtain wall panels can adapt to structural deformation and ensure that the curtain wall panels still meet the watertight and airtight requirements in the case of deformation or displacement.

Costanella Center Building

The Costanella Center Building stands at the northwest corner of the Mapocho River. Looking from a high altitude, it is particularly eye-catching in the entire San Diego building complex. The body wrapped in glass emits a strange light in the sun. The ingenious design makes it It is the tallest landmark building in South America.

Chile, where the building is located, is the intersection of the Pacific plate and the American plate, and is one of the most earthquake-prone areas in the world. Therefore, in the design, dealing with the earthquake problem is an important factor considered in the project design.

The project adopts a unit design with strong earthquake resistance. When designing the horizontal and vertical joints of the unit, the influence of the main structure on the live load and self-weight is considered; On the basis of the structure, screws are used to lock the unit to the yard piece, which can effectively prevent the unit plate from loosening or jumping out during an earthquake. After completion, it can withstand a magnitude 9 earthquake.

Murray Road Curtain Wall Project in Central Hong Kong

The appearance of the Murray Road curtain wall in Central Hong Kong is inspired by the buds of the Bauhinia flower, which interprets the shape and layering of the Bauhinia buds that are about to bloom, and has extremely high requirements for the craftsmanship and precision of the curved glass curtain wall. The external wall design of the project adopts unitized glass curtain wall, with an installation area of 25,000 square meters, including nearly 3,000 flat, single-curved, hyperbolic and tapered glass curtain wall units, and complex curved surfaces accounted for 60%.

In view of the uniqueness and complexity of the exterior design, the project makes full use of BIM technology and digital 3D models to solve technical problems in terms of drawing design, production application, quality control, and construction simulation. Editor/He Yuting
