There are more and more modern steel structure buildings. The quality of the project is the top priority that affects the service life, safety and stability of the building, and is related to the century-old foundation. The quality of the steel structure project is mainly in the design, production, installation, and inspection of the entire project. In the process of waiting, the entire construction process from the beginning of the purchase of materials, to the processing of parts and components to the installation, requires four passes to form a complete set of quality control procedures. As long as all departments strictly follow them, control the quality of the steel structure project. Not difficult, such as underbridge support of viaduct.
(1) Design quality
The design stage is the key to the formation of steel structure engineering quality. Without high-quality design, there will be no high-quality steel structure products. And high-quality design is closely related to the professional quality of designers. A good steel structure project first requires a complete and high-quality design plan. The steel structure building design includes two aspects: one is the steel structure design general drawing, which is a comprehensive general design based on the geology, approval documents, and later use requirements provided by the construction unit, and the basis is determined according to the report provided by the geological survey The type and structure of the steel; calculate and determine the cross-sectional dimensions of steel columns, steel beams, crane beams and other components; the grade and thickness of the steel used; how to match the colors of wall panels and roof panels; and the size of welds. And provide various welding parameters, quality targets, and higher-stage construction design drawings compiled through construction design plans and calculations. These contents will determine the function and quality of the construction project; the second is the compilation of detailed construction drawings, which are decomposed by the steel structure production company according to the design drawings, and the purpose is to directly provide for manufacturing, processing and installation during construction.
(2) Construction quality
The construction quality is not the continuation of the steel structure project, but also a very important guarantee for the project quality of the entire project. The production quality of steel components directly affects the quality of the steel structure project. Because this stage is the implementation stage of physical manufacturing and installation of the structure according to the detailed construction drawings designed. This stage is the main stage of quality formation, so it is necessary to adopt advanced and efficient machinery and equipment, and strictly follow certain construction techniques and procedures to make steel structural components. After construction and installation of qualified components, an overall structure is formed, and a new structural quality is formed. The key to determining the quality of steel structural components production and installation.
(3) Quality acceptance
In addition to the quality inspection and acceptance of each inspection batch, the acceptance of the quality of each component of the steel structure project must also carry out the acceptance of the foundation trench, the acceptance of the main structure, and the completion acceptance of the unit project after the completion of the project. These three parts of acceptance are the quality acceptance jointly carried out by the project contracting unit, project contracting unit, supervision unit, and design unit. Through these quality acceptance activities, to see whether its production quality, construction and installation quality meet the national acceptance evaluation standards or contractual requirements. Therefore, it can be said that quality acceptance is an important activity to check the quality of steel structure projects, and it is a concrete manifestation of being responsible for construction projects. It is the main technical means to prevent unqualified structural parts from flowing into the next process or entering the construction site.
(4) Warranty and maintenance
Every steel structure project can only be delivered to use after the completion of the inspection and acceptance. During the use process, the user needs daily maintenance, and the steel structure production company needs to provide long-term professional inspection and repair, so that the steel structure engineering quantity can be effectively obtained. Continuous maintenance.
