Do you understand the application of steel structures in large industrial shed?

With the development of the economy, steel structures have been more and more widely used in industrial and civil public buildings. Compared with the traditional structure, the steel structure has the advantages of large span, large effective area, convenient industrial production line process layout, smooth logistics, small structural component size, and less steel volume.

All structural components of the steel structure industrial shed can be produced in the factory, mass-produced, with a high degree of industrialization, and the on-site installation is connected by high-strength bolts. The installation is fast, the construction period is short, the applicability is wide, the shape is simple and beautiful, and it has a strong reputation in the construction market. Competitiveness. Compared with the traditional single-story steel structure factory building, it has the following characteristics:

1. The panel of the steel structure industrial shed adopts the profiled steel plate light roof. Because the roof is light, the structure supporting it is also very light. The wall is made of color steel plate, and the architectural shape is simple and beautiful.

2. The large-scale industrial shed adopts a portal steel frame, and the single-span steel frame has a maximum span of 72 meters. In terms of area, it ranges from 1,000 square meters to 80,000 square meters. The area of a single factory is 70,000 square meters, and the example of 60,000 square meters, because it can form a spacious column-free space, which is convenient for flexible internal layout.

3. The lateral rigidity of the steel frame of the steel structure factory building is guaranteed by the couple support, which not only saves a lot of longitudinal steel materials. Also, the flange width of steel frame members can be significantly reduced due to the smaller coupler spacing.

4. The steel frame of the prefabricated industrial shed adopts a variable section, which is proportional to the bending moment. In addition to the variation of the web height, the thickness can also use different sections according to the needs, and the edges of the relevant elements can also use different sections to make full use of the material.

5. The steel frame web of the steel structure industrial shed can be designed according to the effective width, allowing instability, and the strength can be used after buckling. In this way, the height-to-thickness ratio of the rubber plate can be larger than that stipulated in the current steel structure design code, that is, the thickness of the web can be thinner than that of ordinary steel parts.

6. The vertical load of the steel structure industrial shed is usually the design control load, but when the wind load is large or the building is high, the wind load is the control load. Because the structure is light, the earthquake effect cannot be controlled, and the earthquake resistance is generally not considered, and the structural design is very Simple.

7. Due to the lighter components of large industrial sheds, the brackets can meet the requirements through tensioned round steel. Since the steel frame web allows for instability, the brackets can be directly connected to the web, saving a lot of gusset plates.

8. The components of the steel structure factory building are simple to manufacture, the structural components are installed quickly, and the degree of industrialization is high. The component units can be divided according to the transportation conditions, and the bolts are connected on site, and the installation is convenient and fast. The foundation is simple and the construction volume is small. Temporary structures are easy to dismantle.

9. Compared with concrete structures, steel structures have the following advantages: The structure is light in weight, which can reduce the seismic force, thereby reducing the interior of the structure design.

In addition, the reduced weight also reduces base costs, which is more pronounced on soft ground. The steel structure construction speed is fast and the cycle is short, which can put the whole building into use as soon as possible, shorten the loan construction repayment time, and thus reduce the loan interest. It is generally put into use at least half a year in advance, and it is roughly estimated that the use of steel structures saves 15% of the investment compared with concrete structures. Steel structural components are generally manufactured and processed in factories with high precision, and the structural quality is easy to guarantee. The on-site installation is in place, saving employment, the steel structure is dry construction, and the site is civilized, reducing the sand, stone, and cement stacking sites, reducing the storage and transportation of formwork, on-site procurement prefabrication, and on-site pouring of reinforced concrete structures. Construction in the city center or dense residential areas, steel structure buildings are easy to transform during use, in order to improve and expand the internal division of the floor, the changes are simpler and more flexible. Steel structures are suitable for industrial and civil buildings with different heights (single storey, high-rise), different loads, and different types of buildings. With the use of steel parts, steel structures will be more widely used.
