With the continuous development of the construction industry, more and more people choose to hoist steel structures. In the past, they chose to manually lift the house. Now, they all use truck cranes. The construction of multi story steel structure is difficult and the lifting requirements are high, which has attracted the attention of many industry insiders. Let's talk about the key points of multi room steel structure construction. Whether you are a novice or a teacher, it will be good for you to see the hoisting of steel structures.


Fabrication and installation of steel structure works


What are the key points and steps of multi-layer steel structure construction?


Factory production and on-site installation.


The construction of steel structure works shall go through two stages of factory production and on-site installation, and can also go through on-site production and on-site installation. The factory production shall do a good job in the investigation and selection of steel structure production units and installation units, which is of great significance to ensure the quality and progress of steel structure works.


The production process and installation construction organization design of the steel structure project shall be prepared according to the factory production and on-site production stages and installation stages, including the production stage, quality standards, technical requirements, assurance of key component processing methods, main component process flow, process level, process measures, processing equipment, process equipment, etc.


Professional production and installation of steel structures


The production and installation of steel structures is a complex process, from the design, materials, setting out, construction to acceptance of steel structures. There are many steps, many, very complex. If you want to know more details, you can consult Chengneng Heavy Steel Structure! Because the dedicated profession must be completed by professionals, because these are still the most clear things for steel structure engineering companies.


Construction and hoisting of multi-layer steel structure


What is the lifting sequence of steel structure?


Prefabricated steel members


First of all, after the processing of various welded H-shaped steel is completed, the steel members shall be prefabricated and assembled on the steel platform according to the hoisting sequence and process requirements to ensure the welding quality.


The distance between the splicing joint of flange plate and web of section steel shall be greater than 200 ㎜. The splicing length of flange plate shall not be less than 2 times of the plate width; The splicing width of web shall not be less than 300 ㎜ and the length shall not be less than 600 ㎜.


In order to facilitate hoisting and ensure safe and orderly hoisting, the welding quality must be guaranteed. According to the size of the construction drawing, the reinforcement plates, connecting plates, base plates and beams (beams) on the columns and beams shall be welded on the ground steel platform.


In addition to the fabrication and assembly of prefabricated steel members on the steel platform according to the requirements of the construction drawings and specifications, the changes in the on-site installation process and installation dimensions should also be considered.


Through the introduction of steel structure above, we have learned about the relevant contents of production and installation of steel structure engineering. The production and installation of general steel structure engineering shall be completed from the steps of material selection, design, on-site construction, etc.
