Steel Structural engineering is mainly constructed with steel, which is mainly composed of bridges, steel columns, steel pipes and other parts. Their centers are generally connected by welding, bolts, rivets, self tapping screws and other means, which is a major form of construction structure. It has the advantages of light weight and simple construction, and is widely used in large-scale engineering.
The selection of materials for the steel structure project is combined with the cost of investment, and appropriate materials are allocated according to different market demands to maximize the Utility maximization problem of investment. For example, pollution in South China is becoming increasingly severe, and some low-end panels should be relatively allocated for roof maintenance materials to ensure the use time and increase investment costs in the later stage. The remaining materials are consistent with others and can be saved through other methods.
The lifting of steel structures is important, and the construction guidelines should follow the construction sequence of "middle and rear columns", "rear column beams", and "online and offline". A stable frame system needs to be installed in the middle of the house, then pushed towards both ends, and the remaining steel columns and beam components need to be installed.
In order to ensure the integrity of the project construction, it can make the project construction more humanized, facilitate the design scheme and construction of the next stage, and create a steel Structural engineering that combines skills with Plastic arts.
The characteristics are as follows
1. The prefabricated customization rate of the product is high, the construction cost is low, and the construction cycle is short.
In the steel Structural engineering, the system is basically a unified standard, adhering to mass production and manufacturing, and improving the degree of construction industrialization; In the early stage of steel Structural engineering, the production and installation of materials will be integrated, the basic cost will be greatly reduced, the speed of engineering construction will be accelerated, and the construction period will be shortened by about 40%.
2. The steel structure can meet the requirements of super high and large span.
The overall structure of the steel structure is relatively symmetrical, close to the anisotropic homogeneous body, with high compressive strength and high modulus. Compared with glass, concrete, wood, etc., its relative density is much lower. Under the same compression conditions, the weight of steel structure is smaller, and it can produce complex structural types with large spans and widths.
Raw materials can be recycled and reused, which is beneficial for environmental protection and sustainable development.
Steel is a high-strength, ductile, and efficient raw material with good recycling value. It can be recycled even without the use of molds.
