Steel structure is one of the popular construction solutions today thanks to its outstanding advantages such as:
✔ High load-bearing capacity, suitable for large-scale projects.
✔ Outstanding durability, helping the project maintain quality over time.
✔ Easy to transport and install, shortening construction time.
However, to ensure safety, longevity of the project as well as meet technical standards, the steel structure erection process must be strictly implemented according to standards. General contractors must strictly comply with the production, processing and installation stages to ensure the project achieves the highest quality and meets strict technical requirements.
Compliance with standards not only helps the project to be sustainable but also ensures the safety of workers during construction.
1. Steel structure erection standards
Steel structure erection standards is a set of regulations and quality control procedures to ensure the safety, durability and load-bearing capacity of steel structures. Strict compliance with these standards helps the project achieve high quality, optimizes its lifespan and ensures construction efficiency.
1.1 Standards specified in steel structure erection
The Franchising Process steel structure erection must comply with the following standards:
- Steel quality:
✔ Regulations on chemical composition, strength, ductility, and corrosion resistance of steel materials.
✔ Ensure the steel used meets technical standards according to design requirements. - Structural Design:
✔ Methods for calculating loads and bearing capacity of steel structures.
✔ Ensure safety when subjected to impacts such as wind, earthquakes, and construction vibrations. - Installation regulations:
✔ The size and shape of the components must comply with the design drawings.
✔ Installation and fixing methods must ensure stability and safety during construction. - Inspection and acceptance:
✔ Perform structural quality checks according to technical criteria.
✔ Prepare minutes of project acceptance before putting into use. - Maintenance and upkeep:
✔ Maintenance process to maintain structural durability over time.
✔ Detect and handle corrosion and thermal expansion problems to ensure safe use.
5.2 Standards for steel structure erection in Vietnam
In Vietnam, the standards steel structure erection Mainly applied according to:
✔ TCVN (Vietnam Standards) – National standards system on steel structure engineering.
✔ TCXDVN (Vietnam Construction Industry Standards) – Specialized regulations in construction and installation of steel works.
These standards play an important role in ensuring the quality of large projects such as:
✔ Factory, factory.
✔ High-rise buildings, industrial parks.
✔ Traffic works, roads and bridges.
Compliance with standards steel structure erection Not only ensuring safety and sustainability but also optimizing economic efficiency, helping the project operate stably for a long time.
2. Requirements for steel and welding materials
Requirements for steel and welding materials in the process of manufacturing, constructing and assembling steel structures play an important role, determining the quality of the project. Therefore, the steel structure design and construction unit must ensure strict compliance with the following standards:
– All steel before processing must be checked for technical specifications according to design requirements.
– Steel must be classified, labeled, marked and arranged according to cross-section to avoid confusion between steel types. Different types of steel must be marked with different colored paint.
– Steel must be straightened, cleaned of rust, grease and impurities before use. The allowable bending radius and deflection when bending must comply with standards.
– Steel must be stacked securely in a covered house. If stored outdoors, it must be painted with a protective coating. When stacked, it must be placed on a cushion and tilted to allow for easy drainage.
– When transporting steel, a rack is needed to prevent the steel from being deformed.
– Before use, the quality of welding rods, welding wire and welding flux must be checked to comply with the regulations in current standards or technical conditions.
– Welding rods, welding wires and welding fluxes must be dried in the appropriate mode for each type.
– The amount of dried welding rod and flux taken out of the drying oven can only be used for one production shift (if welding low carbon steel) or enough for two hours (if welding low alloy steel).
– The selection of appropriate welding rods, welding wires and fluxes must take into account the strength of the parts to be welded and their weldability. Any welding rods that are peeling or dirty and damaged welding rods must not be used.
– Paint materials to protect steel bridge structures must comply with the regulations of TCVN 8789:2011.
In addition, during the production process of steel structures, the following standards must be followed:
– TCVN 170:2007 – Steel structures – General technical requirements
– TCVN 5574:2012 – Steel structures – Design and calculation
– TCXDVN 314:2005 – Metal welding
– TCVN 3223:1994 – Electric welding rods for carbon steel and low alloy steel
– TCVN 2737:2020 – Steel structures – Requirements for fabrication and installation
3. Standards for steel structure installation in construction works
In the construction industry, the steel structure erection must comply with strict technical standards to ensure the quality, safety and durability of the project. Below are the commonly applied standards:
3.1 European Standard (EN)
EN standards regulate the design of steel structures, including requirements for calculation, material selection, installation and product quality inspection. This standard is widely applied in Europe and has become an important reference for many countries around the world.
3.2 American Standard (AISC)
The AISC standard, developed by the American Institute of Steel Structures, is used in the design and calculation of steel structures in the United States and many other countries. This is a highly popular standard, recognized by major construction organizations around the world.
3.3 Vietnamese Standards (TCVN)
In Viet Nam, steel structure erection follow the standard system TCVN, including provisions on:
- Size and shape of structural members.
- Methods of calculation and design of steel structures.
- Construction installation and quality control process.
Compliance TCVN help ensure high quality construction, suitable for domestic construction conditions.
3.4 Japanese Standards (JIS)
JIS standards are issued by the Japan Standards and Quality Agency and are widely used in the industrial and construction sectors in Japan. These standards are highly stringent, ensuring accuracy in the design and fabrication of steel structures.
3.5 Chinese Standard (GB)
GB standards specify the requirements for materials, design and installation of steel structures in China. This is a set of standards widely applied in the construction industry in this country.
3.6 German Standard (DIN)
DIN standards, developed by the German Standards Institute, are used in many industrial and technical fields, including design and steel structure erectionDIN is highly regarded for its accuracy and safety in practical application.
3.7 International standards (ISO)
ISO is an international standard system, developed by the International Organization for Standardization, widely applied in many industries, trade and services. Compliance with ISO standards helps projects steel structure erection ensure consistency and quality according to global standards.
The application of these standards in steel structure erection Not only does it help the project achieve high quality, it also ensures safety, optimizes costs and increases the life of the project.
