Basic regulations for the construction of steel structure villas in Chongqing

The practical experience at home and abroad shows that the light steel structure house is a promising new technology and new product. However, due to the short application time in our country and the lack of management of design standards, the processing quality is reflected in the main use. The problems are: water leakage on the roof, poor quality of steel components such as steel columns, beams and trusses, rusting of steel components, and low fire efficiency. These problems are closely related to the irregular design and processing of light steel structure houses. Basic rules of steel structure villa: 1. The construction unit of steel structure villas shall have corresponding steel structure engineering construction qualifications and have safety, quality and environmental management systems. 2. Before the implementation of a steel structure construction project, technical documents such as the design of the construction unit approved by the technical director of the construction unit and the special construction plan suitable for the construction unit must be submitted. According to relevant regulations, the supervision engineer or the owner's representative should organize experts as important construction plans and emergency safety plans for steel structure engineering technology. 3. Steel structure construction technical documents and technical contract documents, the construction quality requirements shall not be lower than the relevant provisions of this specification and the current national standard 'Steel Structure Engineering Construction Quality Acceptance Standards' GB50205 4. The production and engineering installation of steel structures must comply with the design and The construction plan requires the construction unit to conduct a technical review of the design documents. When the design needs to be modified, it must be approved by the original design unit, and the corresponding design change documents must be processed. 5. When measuring the structure and quality of steel structures, effective measuring instruments must be used. All professional construction units and supervision units must have unified measurement standards. The above are the basic regulations for the construction of steel structure villas. If in doubt,
