What are the focus of the light steel frame steel structure fabrication?

1. There are many large -scale steel structure engineering construction systems, complex node structures, many welding joint forms, and welding techniques in on -site installation and component production are becoming more difficult. For example, the national stadium “Bird’s Nest” steel structure project has a lot of complex truss pillar, main truss, and sub -structure welding nodes.

2. The construction of large light steel frame steel structure is high, the structure span is large, and the seismic function planning requires high welding quality of the primary steel structure engineering. Such as: the connection weld between the structural column and the beam, the connection welding of the shear pillar and the plate, the stitching welds of the connection weld and column of the beam abdomen column and the plate, etc., are the most important parts of the structure, basically all are all, basically all are all, basically all are all, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts of the structure, basically all are all parts, basically all are all parts, basically all are all parts of the structure, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts, basically all are all parts of the structure. The welded seams of welding are performed on the welding quality.

3. Light steel frame steel structure engineering has many types of steel varieties, and more and more tend to use large thickness steel and low alloy high -strength structural steel. With the increasingly progressive level of steel production technology, cast steel, composite steel plates, and Austenite stainless steel have also been used. Therefore, before the site construction is required, the delivery of steel used in steel structure engineering must conduct welding tests for new steel species in real time, explore scientific and rigorous welding process parameters, and formulate appropriate corresponding welding process methods.

4. On -site installation and factory production links are many, and different types of work of different types of work are large. The installation of steel structure engineering on -site is more difficult.
