Research Of Project Quality Control For Main-Contract In Steel Structure Buildings

With the sustainable development of social economy in our country, the steel structure buildings are used in a large amount. It's heavy difficult and high quality acquiring on the steel construction project, specially the technology of connection and hanging on the senior level or long-span steel structure engineer, leading to an especial subcontracting relationship——main-construction relationship. As the steel construction project with main-construction relationship, its quality controlling also has clearing characteristic. It is very difficult and complex, so how to make a completed quality controlling system and using in a efficient way is a very important part in the steel structure main-construction building. The essays is based on the analysis the speciality of the steel structure main-construction and the general theories of the project quality controlling, and research in it, in order to build a basis of the quality controlling in a systematic way. It's including the following content: 1. Summarize the development and application of the steel structure, and the conception or the characteristics in the steel structure main-construction method; 2. Summarize the general controlling theory and method of the project quality; 3. Analysis and build the quality controlling system on steel structure main-construction project in a very important way; It's including the controlling system and relative code of the steel structure main-construction project, the building of the controlling system (the quality planning building, production factor controlling, working procedure quality controlling, quality accident analysis and dealt, acceptance of construction quality, etc.) The procedure quality concluding the following content: materials quality control, steel element manufacture quality control, meld quality control, high-strength bolt joint quality control, test assembling quality control, erection quality control, painting work quality control and fire prevention work quality control, etc. 4. Program the aided quality control procedure of steel structure main-construction project. Using the programming tool –VB in the Windows operating system, the software named is made in this essay. It base on the steel structure quality control system, and combine many kind of knowledge on steel structure quality control into an expert system. It's convenient and ocular to consult and make into a file of steel structure quality controlling. According to the implementing course of steel structure the program divided into four basic quality control modules, there are contract sign, construction preparation, construct actualization and completion acceptance. 5. Engineering application. Through the application of Procedure to Industrial Factory, Procedure Is Checked up and Perfect。The essay uses the general applicable theories and methods into the steel structure main-construction project, and according to its characteristics to build a complete and systematic steel structure main-construction quality control system, and programming the auxiliary project of it. It has greater guidance and help to the steel structure enterprises on the part of steel structure project quality controlling.
