Steel structures are widely used in buildings, large factories, stadiums, super high-rise buildings, etc.. The surface of the steel material is hot-dip galvanized and fluorocarbon spraying, which is durable, bright and beautiful. There are many kinds of steel structures, which can be divided into seven kinds of common steel structure types: adding steel structure, tower steel structure and stair steel structure according to the structure classification. Now Guangzhou steel structure will give you analysis of these seven steel structures.
1, adding layer steel structure
As the main load-bearing beam, the section steel is connected with the main wall or the supporting points at both ends of the beam. The profiled steel plate shall be laid on the main structure, and then the steel bar shall be laid. The steel bar will be connected with the original structure, and finally the concrete will be poured.
2, villa expansion steel structure
The steel structure villa main structure beam, column, layer support is made up of cold-formed thin-walled steel structure or composite beam. The steel structural member is light in weight, convenient for transportation and installation, and easy to assemble, disassemble and extend.
3. Steel structure of tower
The tower belongs to the high-rise steel structure, the main structure is steel tower is widely used, can be used to support large buildings, factory chimneys and water towers supporting tower, monitoring project, communication engineering and other special purposes.
4. Stair steel structure
The supporting system of steel structure is steel beam stairs stairs as the main structural member, staircase to the pedal plate, the rails to form more parallel string diagonal form. Its features are small footprint, convenient construction, random shape and strong practicability.
5, garage entrance steel structure
Factory manufacturing, site installation, high processing precision, short manufacturing cycle, high production efficiency, fast construction speed, clean appearance, modeling arbitrary.
6. The steel structure of the entrance and exit of the shopping mall
Adopting the reasonable structure system, the technology is advanced, the structure is novel, and the perfect unity of architecture and structure is achieved.
7. Steel structure of level (flat to slope)
The original building steel structure layer (need to dismantle part of waterproof insulation layer and parapet) on new concrete horizontal beam, to connect the steel shelf with the original structure, the layout of steel purlin purlin after laying tile or wood or color steel plate, and the slope layer is arranged on the top of the new tiger window in order to achieve, ventilation and decorative effect.
Guangzhou steel structure is characterized by high strength, light weight, good overall stiffness and strong deformation ability, so it is suitable for building large span and ultra high and super heavy buildings.
