Beads are born in shellfish, and shellfish are born in the sea. The sun and the moon set each other off, and the mountains and seas support each other. Riyuebei is sprinting to the highest hall of China Architectural Quality Award. When I got closer, I found that from the first pile, the Sun and Moon Shell "grew" a steel skeleton piece by piece, inlaid with 1.6 million identical curtain walls-every detail is perfect.
Standing at the foot of Riyuewan, I really appreciate the shock of the word tall. No wonder it always attracts everyone's attention. From the outside, the facade curtain wall project of Zhuhai Opera House is 65,438+10,000 square meters, which is equivalent to a super-large curtain wall project. It is divided into two shell-like buildings, with a small shell of 25,000 square meters and a large shell of 75,000 square meters. Large and small shells are double-layer curtain walls.
It is reported that in order to ensure that the color of the audience hall conforms to the architectural modeling of the Grand Theatre, the color master of Lehua Company of France was specially invited to personally design the facade skin of the theater and personally guide the painting operation. It can be said that the attention to this technology and effect has reached the level of meticulous carving.
As a new landmark of Zhuhai, this project is a building handicraft, which is adjacent to Zhuhai fisherman. It will become a new business card for urban tourism. Although the shape is complex, it requires precision and reflects the aesthetic feeling of the building. "The relevant person in charge of the construction unit Zhuhai Urban Construction Group said.

The facade we see is a perforated aluminum veneer with a glass curtain wall inside. The facades of large and small shells are assembled and installed by 65,438+06,000 perforated aluminum veneers with different sizes and shapes. "The person in charge of Zhuhai Xingye Project, the construction unit, said that each plate has a unique number and needs to be processed and manufactured by a specific manufacturer. The curtain wall skeleton of fixed aluminum plate is made up of 5000 steel squares that have been stretched and bent.
The big shell is 90 meters high and the small shell is 60 meters high. Steel structure is the biggest highlight of the whole main structure. As a bionic building, the components are characterized by arc, complex bending and torsion joints, load-bearing support, and special-shaped components account for 80%. All hoop bars are bent and twisted, similar to the bird's nest, but the cross-sectional size is small and the plate is thin, so it is difficult to control the machining accuracy.
In order to set up artillery shells, at the peak of the construction of the Grand Theatre, 1200 workers fought on the island. Zhejiang Seiko, one of the top 500 Chinese manufacturing enterprises, builds steel structures, which are characterized by "height", "difference", "twist", "welding" and "precision" that are more difficult than the Bird's Nest.
At present, the construction of the main structure and external curtain wall of the whole grand theater has been completed, and the most critical fine decoration construction is underway inside. The Grand Theatre has extremely high professional requirements for sound, light and electricity, and first-class professional teams from Britain, Germany, Australia and Japan have gathered on the island.
The exterior modeling of Zhuhai Grand Theatre has the artistic conception of "pearls are born in shells and shells are born in the sea". In the middle of the shell, a round "pearl" has been formed, which is the core audience hall of the Grand Theatre.

Then, theater architecture is recognized as "the most difficult building" by the world architecture community. Why is it so difficult? Let's go in and have a look again!
In the interior decoration of Zhuhai Grand Theatre, the acoustic requirements are also extremely elegant. The auditorium of Zhuhai Grand Theatre is designed and constructed in strict accordance with the principles of architectural acoustics, so as to ensure that the audience in the last row of the 1550-seat Grand Theatre can hear clearly without using sound reinforcement equipment and achieve perfect audio-visual effects.
At the same time, a large number of new acoustic materials GRG (glass fiber reinforced gypsum board) and perforated sound absorption boards are used in the ceiling and wall of the Grand Theatre, and all of them adopt special-shaped GRG boards. GRG with a thickness of 40 mm weighs as much as 72kg/ m2. It is very difficult to hoist, carry, pay-off and locate this material on site, and the quality requirements are particularly high.
Due to the special shape of GRG, the diffuser shapes of the wall and ceiling of Zhuhai Grand Theatre have been turned over many times, which has brought difficulties to painting construction. The painting of the auditorium of the Grand Theatre needs as many as 14 procedures, such as rough surface treatment of the base, joint patching and leveling, adhesive tape sticking and gypsum powder leveling-twice putty, three times grinding and two times painting, so as to perfectly present the design effect.
Generally, the conventional painting project with the same area only needs more than 300 working days, while the painting of the "pearl" of the Grand Theatre needs more than 1000 working days, which shows the highest level of painting project.
