Universal Studios Beijing applies the domestically pioneered double-L three-fold line precast concrete stand

On September 9, the China Construction First Engineering Division Construction and Development Corporation held the 71st Open Day of China Construction's "Century Building a Century of Concentric Dreams" at the Universal Studios Beijing theme park. Universal Studios Beijing theme park will open on September 20. The two themed scenic spots, "Future Water World" and "Kung Fu Panda's Unrivaled Land", and the Universal Studios Hotel, built by the China Construction First Bureau Construction and Development Company, will be officially opened to the public. The Global Tri-Supply Energy Center will supply energy to all themed facilities within 4 square kilometers of the entire Global Park.

Universal Studios Beijing theme park not only incorporates traditional Chinese cultural elements in the design, but also uses a lot of domestic equipment in the construction, incorporating the wisdom and ingenuity of Chinese builders, showing the world the technology and level of "Made in China" .

The stands of the "Future Water World" theme scenic area are prefabricated concrete components, which have particularly high requirements for appearance and must not be bumped in the slightest. For this reason, 6 hoisting pin holes need to be pre-buried in advance on each grandstand board, and the positions are accurate. In addition, it takes about 40 minutes for the on-site unloading of the truck from the crane in place, the pin fixing, the lifting, the positioning and the removal of the pin, and it takes longer to install a stand. To this end, the project team adopted the self-developed double-L three-fold line shape, which was the first in China, which greatly reduced the number of plates that traditionally used single-L prefabricated stands. At the same time, the L-shaped prefabricated grandstand board is in the form of one piece and one piece from the bottom to the top. The components on site must be consistent with the on-site installation plan, otherwise there will be a secondary reverse transport situation and the overall deployment will be disrupted. The project team communicated and controlled dynamically in real time during installation, so that each grandstand board could be hoisted directly as soon as it entered the site. The time error was reduced within 30 minutes, which reduced the secondary transportation and saved about 1,000 square meters of temporary site. Compared with traditional hoisting, the mechanical time is shortened by about 40%, which greatly improves the installation efficiency. The hoisting of 158 grandstand panels was completed in 10 days.

Universal Studios Hotel is located at the entrance of Universal Studios Beijing and is a must-stop place to enter the park. The overall design of the hotel is Spanish Renaissance style. The dome is located at the highest position of the hotel and the highest point of the entire Universal Studios, with a height of 67.3 meters. In order to meet the requirements of building height limit, fire prevention and non-metallic structure support of the dome, the project team adopted the green high-performance fiber reinforced composite material structure + glass fiber reinforced concrete panel decoration system for the first time in the country to perfectly create the highest point of the park. Precise calculations must be made before the dome is constructed, otherwise the heavy dome will cause cracks in the circular wall that supports it at the bottom. Instead of using a metal structure, the engineers took a different approach and adopted the method of "building blocks", using traditional mortise and tenon structures and modern bolts to splicing and reinforcing the main structural beams of the dome to achieve the balance of the entire structure to support the heavy top. In the early stage, the project team used BIM technology to conduct a 1:1 simulation analysis of the complex joints of the fiber reinforced composite structure, and used 3D printing to accurately adjust the parameters of the entity to ensure that the entire "building block structure" fits perfectly.
