| Both domestic and abroad the development process of the city is quickly more and more more. The developers in order to make full use of construction land area, the basement based on the scope of construction land as far as possible is built.The underground outdoor enclosure structure of concrete formwork can only use unilateral formwork system.Wangfujing international brand Center project is located in the Wangfujing pedestrian street on the west side,.The underground have four floors, building area is 79012 square meters, based on depth of 22.65 meters, only 2 meters from outside of underground outdoor enclosure structure to property line, and between that spaces,there are cast-in-place concrete piles diameter of 1.2 meters, and the peripheral wall thickness of the main structure is 800 mm, and waterproofing of the underground the outdoor enclosure wall is the anti stick waterproof material.Based on Wangfujing international brand Center project underground outdoor enclosure structure, unilateral formwork supporting system is studied(1) Summarized the one-side formwork construction technology application and development in China.(2) With the engineering example, the research studied the construction technology of single-sided formwork for concrete formwork system, described its templates, bracket, and step by step construction technology of concreting process issues.(3) According to the construction process of concrete formwork support system, the study checked its strength, stiffness and stability checking.(4) Combining with engineering examples, the research studied the unilateral formwork system construction management problems from the template engineering quality standard, quality assurance and safety assurance measures, civilized construction etc. and the construction effect are summarized.Through the research, summarizes the construction method and control measures of concrete unilateral formwork formwork system, and provide a reference for similar engineering construction. |
