What are the common seven types of steel structures?

The steel structure construction engineering is mainly based on steel production. The type of steel structure is divided into seven common steel structure types such as adding steel structure, tower steel structure, and staircase steel structure:

　　(1) Add layer of steel structure

　　As the main load -bearing beam, the support point of the main wall or the two ends of the beam is connected. Poly steel plates should be laid on the main structure, and then the steel bars should be laid, and the gluten connections are connected to the surrounding structure of the original structure. Finally, the concrete is poured.

　　(2) Villa expansion steel structure

　　Steel structure villa main structure beams, columns, and shelves are composed of cold -curved thin -walled steel structures or combined beams. The quality of the steel structure components is relatively light, which is convenient for transportation and installation, and is convenient for installation and expansion.

　　(3) Tower steel structure

　　The tower belongs to the high -rise steel structure. The main structural materials are steel pipes. The tower is widely used. It can be used for other special purposes such as the support of factory chimneys, large buildings support, water tower, monitoring engineering, and communication engineering.

　　(4), staircase steel structure

　　The support system of the steel structure staircase is the steel diagonal beam of the staircase as the main structural component. The staircase section is mainly steel pedal. The railing form is mostly the oblique line of the parallel staircase diagonal beam. Its characteristics occupy a small area, convenient construction, casual shape, and practicality.

　　(5) The steel structure of the garage entry and exit

　　Factory manufacturing, construction site installation, processing accuracy, short manufacturing cycle, high production efficiency, fast construction speed, neat appearance, and casual shape.

　　(6).Shopping mall in -entry portal structure

　　The corresponding and reasonable structural system is adopted to achieve the perfect unity of technology, novel structure, and achieve the perfect unity of architecture and structure. The surface of the steel material is hot -dip galvanized and fluorocarbon spraying process, which is characterized by durability, bright, and beautiful.

　　(7), level (Pingxian slope) steel structure

　　By connecting the steel layer frame with the original structure by the newly poured steel concrete in the original building steel structure layer (need to remove part of the waterproof and insulated layer and the daughter wall), the steel layer frame is connected to the original structure, and the steel bars or wooden strips are arranged on it. Color steel plates and tiger windows on the top of the new slope to achieve ventilation and decoration.
