The structure of steel production is one of the main types of building structures. Steel is characterized by high strength, light weight, good overall rigidity and strong deformation ability, so it is suitable for building large span and ultra-high and ultra-heavy buildings. The homogeneity and isotropy of materials are the ideal elastomers, which are in accordance with the basic assumption of general engineering mechanics. The material has good plasticity and toughness, which can be greatly deformed and can bear the dynamic load well. Short construction period; Its industrialization degree is high, can undertake the specialized production with high mechanization degree; High machining accuracy, high efficiency, good sealing, so it can be used to build gas tank, oil tank and transformer. The disadvantage is that the fire resistance and corrosion resistance are poor. Is mainly used for heavy-duty workshop bearing frame, the dynamic loads of the building structure, plate and shell structure, tall TV tower and mast structure, Bridges and warehouse and other large span structure, tall and super-tall building, etc. The steel structure should study high-strength steel in the future and greatly improve its yield strength. In addition, the new type of steel, such as h-shaped steel (also known as broad flange shape steel) and t-shaped steel and pressed steel plates, should be rolled out to meet the needs of large-span structures and super-tall buildings. The steel structure is divided into light steel and heavy steel. There is no uniform standard, and many experienced designers or project managers are often unable to fully understand that they can be considered and judged by some data.
In addition, there is a non-thermal bridge light steel structure system, and the building itself is not energy-saving. This technology solves the problem of cold and hot bridge with ingenious special connections. The small truss structure makes the cable and the upper and lower water pipes pass through the wall, the construction decoration is convenient; Incomparable energy saving is the only building system in the world to build a seven-story house with cold curved thin-walled steel.
The light steel structure residential roof system is composed of roof frame, structural OSB panel, waterproof layer, light roof tile (metal or asphalt tile) and related fittings. Matt construction light steel structure roof, appearance can have a variety of combinations. There are many kinds of materials. Under the premise of protecting the waterproof technology, the appearance has many options.
