Steel structure construction projects are mainly made of steel. The types of building steel structures are divided according to the structural form, and can be divided into seven common types of steel structures such as layered steel structures, tower steel structures, and staircase steel structures:
1. Layered steel structure
The profiled steel is used as the main load-bearing beam to connect the main wall or the support points at both ends of the beam. The profiled steel plate should be laid on the main structure, and then the steel bar should be laid to connect with the surrounding of the original structure, and finally pour concrete.
2. The villa extension steel structure
The main structural beam, column and shelf support of the steel structure villa are composed of cold-formed thin-walled steel structure or composite beam. The steel structure components are light in weight, easy to transport, install, assemble and disassemble, and expand.
3. Tower steel structure
The tower is a high-rise steel structure, the main structural material is steel pipe, the tower is widely used, and can be used for factory chimney support, large building support, water tower tower, monitoring engineering, communication engineering and other special purposes.
4. Steel structure of stairs
The support system of the steel structure staircase is that the steel inclined beams of the stairs are the main structural components, the stair sections are mainly steel plate treads, and the railings are mostly in the form of parallel stair inclined beams. Its characteristics are small footprint, convenient construction, random shape and strong practicability.
5. Garage entrance and exit steel structure
Factory manufacturing, site installation, high processing precision, short manufacturing cycle, high production efficiency, fast construction, neat appearance, and random shape.
6. Shopping mall entrance and exit steel structure
A corresponding and reasonable structural system is adopted to achieve advanced technology, novel structure, and perfect unity of architecture and structure. The surface of the steel material adopts hot-dip galvanizing and fluorocarbon spraying technology, which is characterized by durability, brightness and beauty.
7. Level (level to slope) steel structure
By newly pouring reinforced concrete horizontal beams on the steel structure layer of the original building (part of the waterproof insulation layer and parapet need to be removed), the steel layer frame is connected to the original structure, and after arranging steel purlins or wooden purlins, laying floor tiles or Color steel plates, and dormer windows are set on the top of the newly built slope to achieve ventilation and decoration.
Steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of section steel and steel plates, and adopts silanization, pure manganese phosphating, washing and drying, galvanizing and other rust and rust prevention processes. The components are usually connected by welding, bolts or rivets. Because of its self-weight and easy construction, it is widely used in large factories, venues, super high-rises and other fields.
