National Stadium Prefabricated Stand Slab Quality Control And Installation Of Scheme

The prefabricated concrete industry in China in the fifties and sixties of thetwentieth century, began in the1970s the rise of the1980s peaked in the nineties beganto gradually decline. Today, the large overall construction of prefabricated concretestructures in China is rare, only in a few industries partial use of prefabricated concrete.In contrast, foreign prefabricated concrete industry has been considerable development,is still in the construction industry occupy a certain proportion.This study willinvestigate a large number of domestic and foreign literatures, recombine andsummarize relevant theoretical knowledge, and learn from the development andapplication of foreign prefabricated elements. Then, we will recognize the status anddevelopment direction of our country’s prefabricated elements, and further proposereasonable suggestions.During this study, we will specific analysis the engineering of national stadiumstand slab construction of prefabricated fair-faced concrete. According to theengineering with non prestressed, thin arm plate, the changes of number and type, theprecise position of embedded parts, high quality requirements about appearance andstructure, and rush deadlines, strengthening quality management, and improve the totalsub-unit quality management system to define the quality management objectives,refine the process of quality management in accordance with the principle of"pre-management control, process monitoring, the goal of total control, finished thefinal control", and strictly implement the "responsibilitysystem Jiaodi system, a modelsystem "ten systems. To strengthen the unity, and supervision of co-ordination andintegration of monitoring resources. Process control to achieve "basis, procedures, andrecord the results." Held on a regular basis the quality of training, analysis will be thetopic will be the system, regular meeting."Man, machine, material, method,environmental" factors, according to plan, implement, check processing (PDCA)management model of continuous improvement, the quality of the construction processis always under control, successful realization of grandstand project quality Shimizueffect.On the basis of detailed analysis stand slab installation features and installationconditions, This study will reasonably choose installation equipment, scientific arrange lifting sequence, carefully study installation technology, research and innovateinstallation method, strictly control quality standard and refine the management process,which endure integrated water quality target of precast stand structure.In recent years, the domestic in the prefabricated concrete component constructiontechnology research and application has made rapid development, the technology andconstruction level has been improved.But the overseas fair-faced concrete compared,China in the establishment of acceptance standard system still has inadequacy, still needfurther research and perfection.In this paper the application and construction practice,completed a number of construction technology, technical and management aspects ofthe improvement and innovation, formed a complete set of quality acceptance standard,made the prefabricated concrete bleachers quality acceptance criteria (Beijing cityrecord No. JQB-080-2006), for the construction of similar engineering in the future andmanagement provides the first reference, has a certain value of popularization andapplication.
