With the continuous development of the construction engineering industry, more and more people choose to hoist steel structure projects. In the past, they opted to lift the house manually. Now, they all use truck cranes. The construction of multi-storey steel structures is difficult and the hoisting requirements are high, which has attracted the attention of many people in the industry. Let’s talk about the main points of multi-house steel structure construction. Whether you are a novice or a teacher, it will be good for you to look at the hoisting of steel structure projects.

Steel structure engineering production and installation
What are the main points and steps of multi-storey steel structure construction?
Factory production and on-site installation.
The construction of the steel structure project should go through two stages of factory production and on-site installation, or on-site production and on-site installation. The factory production should do a good job in the investigation and selection of the steel structure production unit and the installation unit to ensure the quality and progress of the steel structure project. significant.
The steel structure project shall prepare the production process and installation construction organization design according to the factory production and on-site production stages and installation stages, including the production stage, quality standards, technical requirements, guarantee the processing method of key components, main components 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, lofting, construction to acceptance of steel structures. There are still many steps, there are many, very complex. If you want to know more detailed information, you can consult Chengneng Heavy Steel Structure! Because dedicated careers have to be done by professionals, as these are still what steel engineering companies know best.

Multi-layer steel structure construction and hoisting
What is the hoisting sequence of the steel structure?
Prefabricated Steel Components
First of all, after the processing of various welded H-beams is completed, the steel components should 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 flange plate splicing seam and the web splicing seam of the profiled steel should be greater than 200mm. The splicing length of the flange plate shall not be less than twice the width of the plate; the splicing width of the web shall not be less than 300mm and the length shall not be less than 600mm.
In order to facilitate hoisting and ensure safe and orderly hoisting, the welding must ensure the welding quality. According to the size of the construction drawing, the column, the steel plate on the beam, the connecting plate, the backing plate, and the beam (beam) are welded on the ground steel platform.
In addition to fabricating and assembling the prefabricated steel components on the steel platform according to the requirements of the construction drawings and specifications, the process of on-site installation and changes in installation dimensions should also be considered.
Through the introduction of the above steel structure, we understand the relevant content of the production and installation of steel structure engineering. Generally, the production and installation of steel structure engineering should be completed from the steps of material selection, design, and on-site construction.
