- Fall protection nets
2.2 Paying Attention to Weather
Erecting steel structures for outdoor constructions like factories and plants requires studying and considering weather factors through weather forecasts to avoid issues that could hinder the construction process.
Heavy rain and humidity can make the construction site slippery, endangering workers at heights, while strong winds can affect the operation of construction equipment like cranes and tower cranes.
By paying attention to weather factors before constructing steel structures, contractors can ensure worker safety, protect assets, improve construction quality, and maintain project schedules. This contributes significantly to building sustainable, safe, and efficient structures.
2.3 Checking Equipment, Materials, Tools, and Transportation
Inspecting equipment, materials, tools, or means of transportation before use, assembly, and construction is an extremely important step. Steel needs to be thoroughly inspected according to quality standards and certificates of origin. In particular, structural bolts and anchor bolts are used to connect important components of the structure in steel-framed buildings.
2.4 Examining the Construction Space
The construction space also needs to be thoroughly inspected, and site preparation should be done carefully. The construction site must be levelled and ensure sufficient stability to bear the weight of the steel structure and construction equipment. The foundation needs to be designed and built to suit the load of the structure.
Cautions During Assembly and Construction of Steel Structures
During the process of assembling and constructing steel structures, many factors need special attention to ensure the quality and safety of the project.
3.1 Steel Structure Design
Steel structure design is the first and the most important step in the construction process. It requires accuracy and careful calculation to ensure the stability and safety of the structure. Design engineers need to consider many factors such as load, environmental conditions, and the intended use of the structure.
During the design process, choosing the appropriate type of steel is crucial. Strength, load-bearing capacity, and cost need to be balanced. Additionally, the design must consider future expansion possibilities and the flexibility of the structure.
Using modern design software such as AutoCAD can help create detailed 3D models, helping to detect and resolve potential issues before construction begins. This not only saves time and cost but also ensures high accuracy during the installation process.
Cautions During Assembly and Construction of Steel Structures
3.2 Supervision of Steel Structure Installation
Supervising the installation of steel structures is an essential part of ensuring that the project is carried out according to design and meets safety standards. Supervisors need experience and in-depth knowledge of steel structures to detect and promptly address any arising issues.
Effective supervision requires diligent adherence to proper installation protocols, which include precise placement of components and meticulous execution of joints and connections. Equally critical is the routine inspection of lifting equipment and verification of its proper usage as a fundamental aspect of supervisory responsibilities.
3.3 Notes on Moving Up and Down the Steel Structure Construction Site
Safety when moving around a steel structure construction site is extremely important. Construction sites often have many dangerous areas, and improper movement can lead to serious accidents.
First, all staff and workers must be fully equipped with personal protective equipment such as helmets, safety shoes, and safety harnesses when working at heights. Safe and clear pathways need to be established on site, avoiding areas with risks of falling materials or equipment.
When moving to high places, safe means such as construction elevators or securely installed temporary stairs should be used. Climbing directly on steel structures is absolutely prohibited. For high-work areas, protective railings and safety nets need to be installed.
In addition, regular safety training and reminders should be organised for all staff on site. This helps raise awareness and emergency handling skills for everyone.
3.4 Checking Scaffolding Locks, Column Systems, Beams and Trusses
For scaffolding, the stability and firmness of the connectors need to be checked. Ensure that scaffolding is installed on a solid foundation and can bear the necessary load.
Check the support bars and braces for any bending or damage.
For the column system, which is an important foundation, careful inspection is needed. Use accurate measuring devices to ensure columns are installed in the correct position according to the design.
For beams and trusses, carefully check the joints, especially welds and bolt connections. Ensure they are executed with proper technique and meet strength requirements. These checks should be performed periodically and after each important installation phase.
If any issues are detected, they should be addressed immediately to ensure the safety and progress of the project.
3.5 Checking Bolt Tightening Force in the Structure
Checking bolt tightening force is an important step in the steel structure installation process, ensuring the stability and safety of the structure. Bolts that are not tightened enough can lead to looseness in the structure, while overtightening can cause unwanted stress or even damage the bolts.
Bolt tightening force checks need to be performed with specialised tools. Strict adherence to standards and regulations on tightening force for each type and size of bolt is necessary.
The checking process should follow a standard procedure, starting with marking the initial position of the nut, then tightening and checking the force. Note that the tightening force may change over time due to material expansion and contraction, so periodic checks are necessary.
Additionally, attention should be paid to environmental conditions such as temperature and humidity, as they can affect the tightening force. In case bolts are found not meeting the tightening force requirements, immediate adjustment or replacement is necessary.
3.6 Checking the Alignment of Main Structures in Steel Frame Workshops
Checking the alignment of main structures in steel frame workshops is a crucial step to ensure the accuracy and stability of the entire structure. Inaccurate alignment can lead to imbalance, affecting the load-bearing capacity and lifespan of the structure.
