Light steel keel structure is a lightweight steel structure with advantages such as light weight, high strength, and easy construction, which is widely used in the field of construction. Below is an analysis of the design and construction techniques for light steel keel structures.

Firstly, the design phase of light steel keel structure needs to consider the following aspects. Firstly, structural load analysis is conducted, including building self weight, rainwater load, wind load, etc., to determine the cross-sectional dimensions and layout of light steel keel according to design requirements. Next is node design, including the connection method between keels, support structure design, etc., to ensure node rigidity and stability. It is the overall structural design, including the arrangement of light steel keel, support structure design, etc., to ensure the overall stability and safety of the structure.

Secondly, the construction technology of light steel keel structure includes the following steps. Firstly, on-site measurement and preparation work, including determining the position, size, and layout of the light steel keel, and preparing for construction. Next is the processing and production of light steel keel, which involves cutting and welding the steel according to design requirements to create a keel structure that meets the requirements. Then there is on-site installation and fixation, transporting the pre made light steel keel to the site for installation, and fixing and connecting it according to the design requirements. It is acceptance and debugging, which involves inspecting the installed light steel keel to ensure the safety and stability of the structure, and conducting debugging to ensure the performance of the structure.
