Hainan Haihua Island 1 # Island E Museum Museum curtain wall installation project (technical experience, the world's best, children's experience), is a project undertaken by Shanghai Meite Curtain Wall Co., Ltd. to build the Haihua Island of China Evergrande Group.

The museum group is located in Haihua Island 1 # Island E area, with a total of 8 halls. The curtain wall installation of 3 individual halls of our company's technology experience, the world's best, and children's experience. The main curtain wall forms are clear frame glass curtain wall, photovoltaic Glass curtain wall, aluminum veneer curtain wall, honeycomb aluminum plate curtain wall, upright seam roofing system, etc., the total area of the curtain wall is about 23,000 square meters.

Due to the high technological content of this project, the tight schedule of each section, and the high quality requirements, the general idea of the project department's construction arrangements is: careful preparation, go hand in hand; strict organization and strict plan management to ensure material supply; improve construction efficiency; strengthen Quality management to ensure quality engineering. The entire project from the deepening of design, material procurement, material processing, material supply, and installation and construction has fully guaranteed the connotation of the architectural culture and can be displayed, meet the architect's requirements for the actual function of the building, and reflect the uniqueness of high-quality buildings And the sense of refinement, to ensure the effective guarantee of curtain wall structure and performance.

The construction difficulty of this project is the steel keel measurement and positioning of four sail towers in the world's most pavilion and five shells of the science and technology experience hall. These two museums have complex curved shapes, variable axis forms, complex axis relationships, and large spans. The curtain wall system requires high planar positioning during construction. During the component processing and overall construction of the curtain wall system, accurate three-dimensional space is required. Model and corresponding key point coordinates to determine the size, shape, and installation position and accuracy of curtain wall components. Therefore, the project design team specially produced a BIM system to meet the mutual constraints of the control points of the curtain wall and automatically generate a three-dimensional model, which plays a key role in the precision control of design, component production and construction. Control measurement and positioning of construction accuracy is the key. We established a control network based on the control points provided by the general contractor to the construction site, and based on the steel structure model of the BIM system, we used 2 total stations for each individual building for measurement and positioning. The project designer, construction manager, and release team of the construction team checked all the control points multiple times to effectively close each other until the measurement accuracy meets the requirements.

The design focus of this project is the design of processing drawings of the four sail-shaped single- and double-curved honeycomb aluminum plates in the world's most pavilion, the science and technology experience hall glass plate and aluminum veneer. Due to the unique shape of the facades of the two museums, the four sail-shaped panels in the world's most museums are mostly shaped double-curved, single-shaped honeycomb aluminum plates. The five shells of the Science and Technology Experience Museum are complex shaped aluminum veneers and glass plates. Difficult, there are many types of glass and aluminum plates (the size of each glass and aluminum veneer are different), and each plate has a large area. The largest piece of hyperbolic honeycomb aluminum plate is 1700 * 2300, which is composed of 7 plates. The design of the honeycomb aluminum plate, aluminum veneer, and glass plate processing drawings of the two museums is difficult and the workload of drawing is huge. It is also necessary to consider the long distances, the difficulty of long-distance transportation, and easy damage during transportation. . The design team of the project department embarked on difficult tasks. In addition to daily on-site technical guidance and handling of technical issues, they worked hard to draw day and night, often worked overtime until late at night, and finally successfully completed all honeycomb panels, aluminum in less than 3 months. The veneer and glass processing drawings are designed with a total of 4,550 drawings, ensuring the progress of factory processing and field installation.

One of the highlights of this project is the photovoltaic curtain wall. Of the entire eight museum clusters, only three of our museums have photovoltaic curtain walls, including monocrystalline silicon (the world's most), polysilicon (children's experience), and thin film photovoltaic (technology experience) And other types. In particular, the science and technology experience hall and children's experience hall are unique in shape, resulting in each polycrystalline silicon and thin-film photovoltaic module being shaped, and each photovoltaic module has a different size. Through the project designer's communication with the owner's designer and photovoltaic supplier for many times, the technical parameters and construction plans of various types of photovoltaic modules were determined, and photovoltaic samples were installed on the physical project. Finally, the installation of the photovoltaic curtain wall was successfully completed. It is worth mentioning that the photovoltaic curtain walls of our three museums are all photovoltaic curtain walls of the entire Haihua Island project. The only company that independently completed the design, procurement, and construction of our company was praised by all departments of Evergrande Group. It was determined as a model project of Haihua Island's photovoltaic curtain wall and won the honor of "Excellent Partner" of Evergrande Group.

At present, the curtain wall installation of the three museums on Haihua Island has been basically completed and is pending acceptance. During the design, procurement, and construction of the entire project, there are also some issues that need us to think about or improve and improve in future projects. For example, in terms of design, is it possible to use a small unit glass plate for the glass plate of the Science and Technology Experience Hall, which reduces the measurement and pay-off workload during the construction process, improves the installation accuracy of the glass plate, and reduces the work load for processing drawings? In terms of construction, when installing the steel framework of the four sail-shaped towers in the world ’s most pavilion, the quality of the installation team ’s installation personnel is higher, the construction experience is richer, the installation accuracy is higher, and the project department ’s quality control management is stricter, so as to avoid In the later period, there was a warping phenomenon during the installation of single- and double-curved honeycomb aluminum plates. In terms of material procurement, during the processing of the single-hyperbolic honeycomb aluminum plate in the world's most museum, can a full-time quality inspector be sent to the factory to supervise the production process? The source strictly controls the quality to avoid the phenomenon that the arc accuracy of the single- and double-curved honeycomb panel is insufficient, and the site is cut, which affects the quality of the installation. There are still some problems, which are no longer explained one by one. The Haihua Island Project Department has discussed and summarized some problems that occurred during the entire project process. It will be improved and enhanced in future projects to create more Quality engineering.
