How to distinguish light steel and heavy steel structures? -wellcamp light steel villa manufacturers

In construction enterprises, everyone has always known steel structure engineering, and steel structure engineering has the distinction of light steel structure and heavy steel structure. How to define them? Many people don't understand this very well. Today, let's talk about the topic of light steel and heavy steel, and teach you how to distinguish between light steel and heavy steel. What is light steel? 'Technical Specifications for Steel Structure of Portal Rigid Frame Lightweight House' specifically refers to the single-layer solid-web portal rigid frame structure type of light roof and light outer wall (masonry outer wall can also be used conditionally). The point is that the enclosure is made of lightweight raw materials. The raw materials used in the light steel structure engineering building system are usually hot-rolled light-weight H-steel, light-weight welded steel, high-frequency welded steel, cold-formed thin-walled steel, thin steel plate and thin-walled steel pipe and other efficient structural types of steel and efficient new types of steel. It is a light-duty fully-assembled steel structure project that takes functional materials as the leading role and is assisted by various efficient decorative designs and connected raw materials. Differences in the design and application of heavy steel When the design of light steel structure is used, the strength of the web after buckling is considered, which can reduce the setting of stiffeners and promote the reduction of the amount of steel used. This is light steel structure. Otherwise, the amount of steel will be more and more, that is, the heavy steel structure. For example, when the tonnage of the crane exceeds 25 tons, the heavy steel structure needs to be used, and the safety and reliability of the light steel structure is far from enough. Light steel and heavy steel can comprehensively refer to many data information:·Plant crane lifting weight:≥25 tons, is a heavy steel structure.·Steel consumption per square meter:≥50kg/㎡, it can be considered as a heavy steel structure.·Key prefabricated steel plate thickness:≥10mm, light steel structure is used less. In addition, there are also reference dimensions such as the project cost per square meter, the weight of the larger prefabricated components, the larger span, the structural form, and the eaves, etc. The above types can give empirical data information when distinguishing whether it is heavy steel or light steel. Technical specifications for structural types of light buildings, only for their“light”features and expressly stipulates many more practical contents. In order to distinguish light steel structure villas, it may be called ordinary steel structure projects as“plain steel”more suitable. Because the scope of ordinary steel structure engineering is very wide, it can include all kinds of steel structure engineering. Light steel and heavy steel, the design attention First, the confirmation of the roof beam section height. Usually take 1/8-1/10 of the span of the beam, and the stirrup encryption area is one third of the two ends. Usually, the stirrup encryption is the encryption of the two ends of the beam. Start from the support, and control the length of the encryption area. Secondly, compared with the steel frame beam, the two ends are small and the middle is large. The actual project needs should be used as a reference. Usually, what you see are beams of equal section. In rigid frame analysis, under static load, the positive bending moment in the beam will be larger than the negative bending moment at the end of the beam, unless the dynamic load is only arranged It is only possible in specific cases where adjacent spans are not arranged in this span. To this end, it is required to make the roof slope 1:10, taking into account the specific circumstances of wind load and single-slope plus vertical load, and the actual quantitative steel usage based on the specific conditions of the project site. Finally, the beam and column specifications for the design of steel structure engineering, first confirm the form of steel prefabricated components, such as I-shaped, groove, mouth, etc., and then confirm the specifications according to floor height, slenderness ratio, aspect ratio, etc., Finally, according to the feasibility of software re-examination, according to this method, the amount of steel used is confirmed. Application of heavy steel structure and light steel structure: light steel structure is widely used in general industrial and agricultural, commercial and service buildings, such as office buildings, villas, warehouses, stadiums, entertainment, tourism buildings and low and multi-storey residential buildings. , It can also be used for adding layers, renovation, reinforcement and building materials of old houses, areas with inconvenient transportation, tight construction periods, movable demolition buildings, etc. Heavy steel structures are widely seen in petrochemical plant facilities, power plant plants, large-span stadiums, exhibition centers, and high-rise or super-high-rise steel structures.
