With the rapid development of today's engineering construction field, more and more people choose to hoist steel structure projects. Previously, at the building level, manpower was selected for hoisting. At present, all cranes are used. The double-layer steel structure is difficult to install and has high hoisting regulations, which has attracted the attention of many professionals. Below, Chengneng Steel Structure will talk about the key points of multi-house steel structure installation. Whether it is a newbie or a teacher, take a look at the hoisting of steel structure projects. All are beneficial to themselves.

Steel structure engineering production and installation

The engineering construction of the steel structure project must go through two stages of factory fabrication and on-site installation. At the same time, it can also be fabricated and installed on-site, and the factory fabrication should do a good job in the investigation and selection of steel frame structure manufacturing enterprises and installation units. Among them, it has key practical significance for ensuring the quality and progress of steel structure engineering.

For the steel structure project, the production process and installation construction design plan should be customized for the factory production and on-site production links and installation stages. The production and processing technology content should include the production process of each process, the testing standards and technologies of each sub-item. Standards, and various specific measures formulated to ensure product quality, such as the production method of important parts, the production process of key components, the technical level, the processing technology countermeasures, the production equipment adopted, the processing technology weapons and equipment, etc.

What is the hoisting sequence of the steel frame structure?

Prefabricated components of steel structures

At first, after the production and processing of various electric welding H-beams are completed, the prefabricated components and assembly of steel structural parts are carried out on the steel structure platform according to the hoisting sequence and technical regulations, so as to ensure the quality of electric welding and welding.

The distance between the spliced ​​web splicing joint of the channel steel and the splicing joint of the beam end should exceed 200mm. The length of web splicing shall not be less than 2 times the plate width; the total width of beam end splicing shall not be less than 300mm, and the length shall not be less than 600mm.

In order to make hoisting more convenient and ensure the safety of hoisting in an orderly manner, the welding quality of electric welding must be ensured. (Beam) etc. on the pavement steel structure platform to carry out group butt welding according to the specifications of the construction drawings.

In addition to making and assembling the steel components of the prefabricated components on the steel structure platform according to the construction drawings and standards, the process performance and the change of the installation specifications should also be considered on the spot.

According to the detailed introduction of the above steel structure, you have understood the relevant content of the production and installation of the steel structure project. Generally, the production and installation of the steel structure project should be carried out from the process of material assembly, design scheme and construction site construction.
