Nanjing Shimao “Binjiang New City”, a large-scale super high-rise residential building developed by Nanjing Shimao Real Estate Development Co., Ltd. and designed by Shanghai East China Architectural Design Institute and is about to be completed, is promoting the application of building energy-saving exterior wall insulation. On the road of system technology, facts have proved the feasibility of applying this new technology of exterior wall insulation system in super high-rise buildings. The exterior wall insulation system technology of this project uses the "ZL rubber powder polystyrene particle exterior wall exterior insulation complete system technology" product developed by Beijing Zhenli High-tech Co., Ltd.
Nanjing is located in an area with hot summers and cold winters. When selecting a thermal insulation system, not only the thermal insulation performance of the system must be taken into consideration, but also whether it has excellent thermal insulation effect. The main structural wall of the "Binjiang New City" project is a pure shear wall, with a construction area of ??more than 70,000 square meters above ground and more than 3,000 square meters underground. The building structure is relatively complex. Unit 5-1 has a 47-story height of 141.5 meters; 5-2 The 50th floor of unit 150.5 meters high; the 53rd floor of unit 5-3 is 159.5 meters high. This project is by far the largest external wall insulation construction area, highest height and most difficult among domestic single building projects. Since the project is located on the bank of the Yangtze River, where the wind pressure is high, the system must be a seamless and cavity-free system to improve the ability to withstand wind pressure. The project floor is extremely high, so safety protection measures are particularly strict, and its outer eaves and walls vary. , the total deviation is large, the insulation solution must be required to have strong positive ability to structural deviation; at the same time, when using exterior wall insulation system products in high-rise buildings, especially super high-rise buildings, the fire protection capability of the system must also be considered. From the beginning of the insulation construction, Party A required that the entire external insulation construction period be completed within 60 days. Due to the long vertical transportation distance of the project, climbing frame construction could only be used. The difficulty of applying external wall insulation in such a super high-rise building can be imagined.
On November 30, 2005, Beijing Zhenli High-tech Co., Ltd. and Nanjing Shimao Real Estate Development Company held a technical demonstration meeting, inviting well-known experts in the fields of domestic building materials research and development, production and application. , and together with relevant departments and technical experts from Jiangsu Province and Nanjing City, comprehensively analyzed and discussed the technical and construction feasibility of using "ZL rubber powder polystyrene particle exterior wall insulation system" for the WTO "Binjiang New City" super high-rise residential project, experts We conduct technical comparative analysis and conduct detailed review of possible problems. Experts agree that the "ZL Rubber Powder Polystyrene Particle Exterior Wall Exterior Insulation System" developed and produced by Beijing Zhenli High-tech Co., Ltd. has no seams and cavities, excellent fire protection performance, good air permeability, flexible gradients, and stress relief layer by layer. and other characteristics, in line with the material selection requirements of the project.
Experts said that the ZL rubber powder polystyrene particle exterior wall insulation system has undergone nearly 10 years of actual engineering application testing and has undergone the most stringent large-scale weather resistance tests in different regions of the country several times. Obtained such patents as crack-resistant insulation wall and construction technology (Patent No.: ZL98103325.3), plastic composite fiberglass mesh cloth (Patent No.: ZL98207104.3), external insulation and post-anchoring and pasting brick wall (Patent No.: ZL03264433). 7) A number of patented technologies such as rubber powder polystyrene particle external insulation and pasting brick wall and its construction method (Patent No.: ZL02153345.8). This type of complete technical system has no cavities and has good thermal insulation and wind resistance. pressure, fire protection, crack resistance, moisture resistance, sound absorption, sound insulation and vibration reduction. Especially after conducting large-scale weather resistance tests on this type of system, there was no hollowing or falling off in the system, no blistering or cracking in the anti-cracking protective layer materials and facing layer materials, and no cracking or peeling in the entire thermal insulation system. Among the specimens with pasted tiles, there was no deformation of the tiles, no cracking at the joints of the tiles, and no falling off of the tiles. All indicators met the corresponding standard requirements.
In order to ensure responsibility for project quality, Beijing Zhenli High-tech Co., Ltd. is the first in the industry to fulfill its promise to users across the country: for a complete set of projects constructed using ZL products and process requirements, the quality guarantee period is 25 years. . It is worth mentioning that in 2004, the corporate standards and procedures compiled by ZL Technology System were used by the national competent authorities as the basis for national industry technical standards. In August of that year, the industry standard JG158-2004 for rubber powder polystyrene particle exterior wall insulation systems, which was based on ZL enterprise standards, officially came into effect and was widely promoted and used.
By the end of 2005, the total number of projects using ZL's complete set of technical systems for external insulation reached 20 million square meters across the country. Zhenli Company has developed into a real "giant" in the domestic building energy-saving external insulation industry.
The application of new exterior wall external insulation system technology products in Nanjing Shimao's "Binjiang New City" super high-rise building has completely changed the long-term misunderstandings among industry insiders about the application of external wall external insulation system technology in super high-rise buildings. , which proves that only continuous technological innovation is the best and only way to implement the development and application of building energy-saving technology.
