Steel frame construction is a modern construction technology, which is mainly composed of steel columns and steel beams made of section steel or steel plates, which together form the load-bearing frame of the building. This type of structure is very common in industrial and commercial buildings, especially when large spans of space or high-rise buildings are required.

Steel frame building features

Material selection: Welded H-shaped steel and hot-rolled H-shaped steel are usually used as the main load-bearing skeleton, because these two kinds of steel have good mechanical properties and economy. C-shaped steel and Z-shaped steel are often used as auxiliary structural components such as purlins (beams supporting roof panels) and wall beams.

Connection method: The steel column and steel beam can be bolted or directly welded to fix, in most cases in order to ensure the overall stability and choose a rigid connection. For portal frame, the single-span design tends to use full rigid joints; In a multi-span arrangement, a combination of rigidity and articulation may be used to facilitate construction and improve flexibility.

Roofing and wall materials: Corrugated metal sheet has become one of the preferred materials because of its lightweight and high-strength characteristics, which can not only provide sufficient protection, but also enhance the appearance of beauty. In addition, products of different thicknesses or colors can be selected according to specific needs to achieve the best results.

Thermal insulation measures: In order to improve the indoor environmental quality and save energy consumption, the interior of the wall is usually filled with polystyrene foam, rigid polyurethane foam, rock wool or glass wool and other efficient insulation materials. These substances can not only effectively prevent heat transfer, but also have good fire retardant properties.

Foundation treatment: The bottom of the column can take a rigid connection or can be hinged to connect with the foundation, depending on the project requirements. If it is the former, it means that the whole structure will be more stable and not easy to deform; The latter allows a certain degree of displacement adjustment, which is conducive to responding to the impact of changes in geological conditions.

Steel frame structure with its superior physical properties, flexible design possibilities and relatively low cost input, in today's society has been widely used and developed. With the progress of science and technology, more innovative technologies and new materials will be introduced into this field in the future, further promoting the construction industry to a higher level.
