What are the standards for residential steel structure, steel structure construction standards?

In accordance with the requirements of the Constitution of the People's Republic of China and the national development plan, the Ministry of Housing and Urban-Rural Development put forward the "Evaluation Standards for Steel Structure Housing". This standard aims to promote the technological innovation and sustainable development of housing construction, improve the quality of housing construction in China, and meet the people's needs for a better life.

The evaluation criteria mainly include the following aspects:

First, security. The safety of steel structure housing is one of the core contents. The standard clarifies the relevant safety specifications and technical requirements that should be followed in the design, construction and use of steel structure housing to ensure the safety of the residential structure in terms of structural stability, fire prevention and control, and seismic resistance.

Second, energy conservation and environmental protection. Steel structure houses have greater potential in terms of energy consumption and environmental protection. The standard will evaluate the energy-saving performance of steel structure housing, including the selection of building materials, thermal performance, thermal insulation, energy utilization and other indicators, so as to ensure that the housing can effectively save energy and reduce pollution emissions.

Third, comfort. The living comfort of steel structure houses is an important issue that people are concerned about. The standard will ensure that the home has a positive impact on the health and comfort of residents by assessing the comfort indicators of the residential interior environment, including aspects such as lighting, ventilation, noise control, etc.

Fourth, durability. The durability evaluation of steel structure housing is an important part of ensuring the long-term use of housing. The standard will verify the service life and quality of residential materials by testing the corrosion resistance, aging resistance, durability and other indicators of residential materials.

The Ministry of Housing and Urban-Rural Development put forward the "Evaluation Standard for Steel Structure Housing", which aims to promote the transformation and upgrading of China's housing construction industry and promote the healthy development of the steel structure housing industry. The implementation of this standard will help improve the quality of housing construction and meet the people's needs for a better life, while also being in line with the country's strategic goals for sustainable development.

Steel structure design standard: GB50017-2017.

The national standard "Steel Structure Design Standard" was approved and issued by the Ministry of Housing and Urban-Rural Development No. 1771 on December 12, 2017, with the number GB50017-2017, and will be implemented from July 1, 2018.

The main technical contents of the standard include: general principles, terms and symbols, basic design regulations, materials, structural analysis and stability design, flexural components, axial stress components, tensile bending, compression-bending components, stiffened steel plate shear walls, plastic and moment amplitude modulation design, connections, nodes, steel pipe connection nodes, steel and concrete composite beams, concrete-filled steel tubular columns and joints, fatigue calculation and anti-brittle fracture design, seismic performance design of steel structures, steel structure protection, and appendices a-k.

Standards are one of the important standards in the field of construction engineering. The standard comprehensively summarizes the research results and engineering practice experience in the field of steel structure in China in recent years, and the technical content is scientific and reasonable, and the operability is strong, and its release and implementation will further promote the sustainable development of steel structure buildings.

Steel structure engineering construction work round car requirements:

1. It is necessary to do a good job in the inspection and selection of steel structure production and installation units.

2. Strictly review the steel structure production process and installation and construction organization design submitted by the contractor.

3. It is necessary to pay full attention to the supervision of the production stage.

4. Supervision of the installation stage.

5. On the test and inspection of steel structure engineering.

6. Several other important quality control points of steel structure engineering.

Among them, several other important quality control points of steel structure engineering are as follows:

1. The pre-embedding of anchor bolts. The embedded quality of anchor bolts directly affects the installation quality of steel structure, and it is of great significance to control the position, verticality, length and elevation of anchor bolts (groups) to reduce reaming and adjust the workload (and even avoid rework), and improve the quality of structural installation. The embedded method of anchor bolts can be directly embedded method, or the lead cavity wax can be used by the reserved hole method.

Before pouring the foundation concrete, the supervision engineer must strictly check the rationality and reliability of the embedded bolt construction method, as well as whether the measured indicators are within the scope of the specification.

2. Quality control of welding engineering. Welding engineering is one of the most important sub-items of steel structure production and installation engineering, and the supervising engineer must be engaged in pre-preparation, welding process and finished product inspection, and effectively do a good job in the quality control of welding engineering.
