In the ever-evolving urban landscape, the demand for space is continuously on the rise. Adding floors to existing buildings using lightweight steel structures has become a common solution. This construction method not only expands the usable space of existing steel structure buildings but also optimizes functionality without the need to demolish the original building. 

 

Before embarking on the addition of a floor using steel frame structures, the first task is to assess the load-bearing capacity of the existing steel structure building. This step is crucial as it directly affects the feasibility and safety of the additional floor. Professional steel structural engineers calculate whether the existing structure can withstand the load of the new floor. If not, reinforcement of the structure is required before proceeding with the design and construction of the steel framed structures. This step is fundamental in ensuring the safety of subsequent construction and avoiding future structural safety issues.

 

Once it is confirmed that the existing structure can meet the demands of the additional floor, the next step is to design detailed plans for the lightweight steel structures and begin the fabrication of components. This phase requires precise calculations and design to ensure that the new floor's light steel structures perfectly match the existing structure. After the components are fabricated, they are transported to the construction site, ready for installation.

 

At the construction site, the first task is to align the site with the drawings to identify the position of the axes and pre-embedded components. This step demands high precision to ensure the accurate installation of the prefabricated steel buildings. Subsequently, protective setups are erected around the site to ensure the safety of construction personnel and the smooth progress of the construction.

 

The installation of light prefabricated steel structure building is the core phase of the entire floor addition project. This step includes the sequential lifting and installation of columns, beams, purlins, and other components. During the installation, professional equipment and tools are used to ensure that each component is precisely placed in its designated position. The accuracy of this step directly affects the stability and safety of the entire structure.

 

After the installation of the lightweight steel structures, the next task is paneling, including the installation of roof panels, wall panels, and the processing of the core tube. This step is not only related to the appearance of the building but also affects its functionality and practicality.

 

Since the construction process may damage the original waterproof layer, waterproofing treatment must be carried out after the paneling is completed. This step is crucial in preventing rainwater leakage and protecting the internal structure of the building from water damage.

 

The construction of new walls must be carried out in accordance with the existing structure, and then handed over to the decoration team for subsequent decorative work. This step is the ultimate realization of the building's aesthetics and functionality.

 

Throughout the entire process of adding floors with lightweight steel framed structures, each step requires strict control and precise operation. From the assessment of load-bearing capacity to the final decorative work, every step is vital, not only concerning the safety of the building but also affecting its service life and functionality. With a professional construction team and strict quality control, adding floors with lightweight steel structures can become an effective way to expand urban building space.

The arrival of the rainy season presents a significant challenge for the construction of lightweight steel structures. During this period, it's crucial not only to maintain the pace of construction but also to ensure the quality and safety of the work. This article will introduce key measures to consider when installing lightweight steel structures during the rainy season and how to address the challenges brought by the rain through these measures.

 

When constructing in the rainy season, we adhere to the overarching principle of "adequate drainage, water blocking, and waterproofing." Our goal is to ensure that indoor projects remain unaffected by the rainy season, while outdoor projects continue in light rain, pause during heavy rain, and resume swiftly after a storm. Although the quality of construction on rainy days may be lower than on sunny days, appropriate measures can minimize this impact.

 

It's essential to gather meteorological information to prepare thoroughly for construction during the rainy season. Under the leadership of the technical director, technicians are responsible for compiling technical measures for rainy season construction and providing detailed guidance. Besides, steel structure project managers are in charge of coordinating the human, financial, and material resources needed for rainy season construction to ensure smooth progress.

 

Lightning protection is crucial during rainy season construction. All formwork must be elevated from the ground when stacked to prevent damage from water immersion. Formwork release agents should be covered with plastic sheets after application to prevent the isolation layer from being washed away by rain. For steel structure materials, effective covering is also necessary, ensuring that the storage area has a good drainage system to prevent rusting due to water immersion.

 

Welding work of prefabricated steel structures should not be conducted in the rain, but it can be protected by constructing processing sheds. Welding machines, wires, and gas cylinders should be stored in dedicated sheds to prevent moisture damage. During welding of prefabricated steel structures, it's important to prevent rain from affecting the quality of the welds. As for high-strength bolt installation, during the rainy season, it's essential to ensure that construction personnel have rain gear and to pay special attention to electrical safety during prefabricated steel structures construction.

 

Temporary electricity sites need to be protected during rain. The power should be cut off when not in use to prevent electrical accidents. For scaffolding, it's mandatory to inspect the clamps one by one before and after the rain and ensure that the foundation is solid. During inspections, construction and inspection personnel must ensure their safety measures are in place, paying attention to slip prevention and fall protection.

 

Although the rainy season brings many inconveniences to the construction of portal frame steel structure, by taking the aforementioned measures, we can effectively address the challenges posed by the rain. The key lies in advance preparation, scientific management, and strict implementation of safety measures. In this way, even during the rainy season, we can ensure the quality and safety of portal frame steel structures and complete construction tasks on time.

In August 2024, a groundbreaking achievement on the International Space Station (ISS) revolutionized the field of metal manufacturing—successfully utilizing 3D printing technology to fabricated sheet metal parts in space for the first time. This feat not only marks a significant leap in space manufacturing but also paves new paths for future space exploration and orbital production and maintenance missions.

 

Led by the European Space Agency (ESA), this pioneering mission has proven the feasibility of printing metal parts in a microgravity environment. The metal 3D printer, developed by Airbus and its partners with funding from ESA, arrived at the ISS in January 2024, with its core objective being to explore the possibility of printing metal parts in such a unique environment.

 

Traditional space exploration missions require all parts to be produced on Earth and transported to orbit, a process that is costly and logistically complex. The application of metal 3D printing technology enables astronauts to potentially manufacture tools, parts, and even replacement parts directly in orbit, saving time, reducing costs, and enhancing the self-sufficiency of space missions, especially for long-term missions.

 

Due to the effects of microgravity, space manufacturing is much more complex than manufacturing on Earth. Traditional manufacturing methods rely on gravity to position materials and guide the process flow, and in a microgravity environment, the behavior of processes like molten metal deposition is unpredictable. Engineers had to develop new strategies and technologies to adapt the 3D printing process to these challenging conditions. The ISS provided a unique testing platform for these challenges and the development of viable solutions.

 

After the printer arrived at the ISS, astronaut Andreas Mogensen played a key role in installing the machine. Safety was the top priority for the project, with the printer being sealed to prevent any harmful gases or particles from escaping into the ISS atmosphere. This process also included careful control of the printer's internal environment to minimize risks during operation.

 

The actual process of 3D printing began with the deposition of stainless steel. Unlike traditional desktop 3D printers that use plastic filaments, this printer uses stainless steel wire melted by a high-power laser, which heats the metal wire to over 1200°C and deposits it layer by layer onto a moving platform.

 

By mid-July 2024, the team had successfully printed 55 layers, marking the completion of half of the first sample. This achievement heralds the start of the so-called "cruise phase," where the team was able to accelerate the printing process. These optimizations have made the printer's operation more efficient, increasing the daily printing time from 3.5 hours to 4.5 hours.

 

The successful application of metal 3D printing technology not only provides greater flexibility and self-sufficiency for space missions but also has a profound impact on the field of metalworking and manufacturing. This technology can be used to manufacture everything from spare parts to large structures in space, supporting long-term exploration and colonization of other planets. As technology continues to advance and improve, we can look forward to more innovations and breakthroughs in the field of space manufacturing through metal 3D printing.
