The on-site observation and technical exchange meeting of Jiangsu Grand Theater roofing project was a complete success< /p>

    On November 19, 2015, the on-site observation technology exchange meeting for the roofing project of Jiangsu Grand Theater hosted by the Construction Steel Structure Branch of China Construction Metal Structure Association and undertaken by Shandong Yabaite Technology Co., Ltd. was held at Held in Nanjing, Jiangsu Province. More than forty experts, scholars, and business representatives from all over the country walked into the construction site of the Jiangsu Grand Theater to observe and observe. The meeting was presided over by Dong Chun, vice chairman of the Construction Steel Structure Branch. Dang Baowei, deputy secretary-general of the China Construction Metal Structure Association and chairman of the Construction Steel Structure Branch, said that the organization of this event is an important part of the implementation of the two-year action of the Ministry of Housing and Urban-Rural Development of the project quality management. Learn and communicate with each other to effectively promote the improvement of the quality of metal roofing projects in the construction industry. It is reported that the project will be completed in 2016 and will be officially opened to the public in 2017.

    The Jiangsu Grand Theater on the banks of the Yangtze River is the largest cultural project in Jiangsu Province. It has been constructed for nearly three years. The construction area is 19.66 hectares, the total construction area is 271,400 square meters, and the investment is about 2 billion. Yuan. According to the designer of the project, the overall design of the Jiangsu Grand Theater takes water as the theme, in the shape of "lotus leaf droplets". The 4 "droplets" are 4 halls, namely a concert hall, a theater hall, an opera hall and a variety hall. There is also a public hall in the center. In addition, a 12-meter-high "lotus leaf" elevated platform will be built to hold the "water droplets". 4 "water droplets" are evenly distributed around the 70mX60m oval outdoor central square, forming a semi-enclosed enclosure. The shape of the space is in the shape of a lotus leaf and water drops, which fully reflects the characteristics of "Water Rhyme Jiangsu".

    At the meeting, Zhou Zhigang, manager of the design department of Shandong Yabaite Technology Co., Ltd., introduced the difficulties in the design and construction technology of the metal roof of the Jiangsu Grand Theater. The hyperbolic water drop shape, the daylighting skylight is in the shape of a streamer, and the partial arc is curved. This requires high precision in the installation of the keel. At the same time, in order to express the characteristics of the building's "Water Rhyme Jiangsu", combined with the cultural connotation of Nanjing, the titanium composite panel was finally selected as the main The decorative surface and the decorative plate keel are supported by aluminum round pipes to meet the needs of the architectural effect. This not only increases the difficulty of processing, but also brings challenges to assembly; in addition, due to the large number of gutters in the project, and each gutter from It is hyperbolic from top to bottom, and the gutter design is also a difficult point in this project, which directly affects the waterproof performance of the roof. Therefore, the project adopted BIM technology from the design stage for simulation analysis and lofting, and demonstrated the simulated construction through the animation model. This is the first time it has been used in the construction of the National Theater Series.

    As the organizer of this technical exchange activity, Yabaite chairman Lu Yong introduced the company's development history, company profile and future development direction of the company at the meeting. Yabaite is a young, energetic and hardworking enterprise. The company was established in 2009 in Zaozhuang, Shandong. Under the leadership of Chairman Lu Yong, the company spent 6 years on the Shenzhen Stock Exchange in August 2015. The small and medium board successfully completed the backdoor listing and became the first listed company in the domestic metal enclosure with stock code 002323. After the company is listed, Yabaite will continue to adhere to the corporate philosophy of "green, environmental protection, energy saving, and innovation", use the capital market to promote technological innovation, lead the development and progress of the industry, and strive to build Asia's first-class metal roof enclosure system integration service supplier.

    Gu Yanqing, President of Jiangsu Steel Structure Association, said at the meeting that the steel structure industry in Jiangsu Province is a relatively large industry in Jiangsu. There are more than 2,700 steel structure qualification enterprises, and the main qualification steel structure enterprise There are more than 700, and the development of metal roofs has played a very good role in promoting the structural adjustment of steel structures in Jiangsu Province. With the rapid development of metal roofing and enclosure systems in recent years, engineering quality problems such as wind exposure and rain leakage have occurred from time to time. The Construction Steel Structure Branch of China Construction Metal Structure Association has been paying attention to the problems of metal roofing and wall construction. Help companies find problems and find solutions. The party guard emphasized that the quality of metal roofing projects has always been an important task of the association. The association will continue to hold such activities to enhance the awareness of construction enterprises to create excellence and strengthen the governance of project quality is the need for the transformation and upgrading of the steel structure industry.
