Steel structure construction has once again proved to have strong seismic capacity, so the development of steel structure in the international construction industry has become an irresistible trend, so we should also seize the opportunity to develop China's steel structure, in the process of future development. First, we must clarify our development goals.
In order to promote the rapid development of steel structure in China, steel structure or steel mixing mechanism should be limited in the design and construction of high-rise and super high-rise buildings. For large-span buildings, space grid structure and three-dimensional truss conjunction structure are actively adopted, while the promotion of light steel structures, such as light steel residential buildings and light steel villas, is also increased.
Expanding the Application Areas
Steel structure building is already recognized as the representative of “green building” in the construction industry. It is a new type of energy-saving and environmentally-friendly building system, which is in line with the national strategic goal of sustainable development, and China has already built factories, large-span factories and stadiums. Residential houses, bridge projects, high-rise buildings, etc. have been widely used, but there are still some areas that are still blank.
Localization of steel
So far, China's high-rise and super-tall buildings have been co-operated from local to foreign countries and are the products of Sino-foreign cooperation. Because of the rapid development of steel structure construction, many foreign companies have flooded into China, and have already obtained a large amount of sales in China. Although we have reached a certain level, we still need to rely on foreign power. This requires us to upgrade our advanced technology and cultivate professional talents to achieve true domestic technology.
The advantage of the steel structure workshop is that its advantages such as light weight, high strength, large span and short period construction have won the favor of consumers. The construction of steel structure workshop is not a simple project, and the raw materials used cover a wide range:
H section steel
H-section steel is generally used to make steel beams and steel columns. H-section steel is the most common and most commonly used steel structure engineering. H-section steel is named because its section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance, simple construction, cost saving and light weight in all directions, and has been widely used.
C,Z section steel
purlin is generally used in C,Z section steel. C-shaped steel is automatically formed by C-shaped steel forming machine. Z-shaped steel is a common cold-formed thin-walled steel with a thickness of generally 1.6-3.0mm and a high cross-section of 120. -350mm between. A horizontal component of the steel structure distributed along the length of the roof, located on the main raft, supporting the secondary eaves as a purlin.
Bracing tie bar support bracing steel
The braceing, tie rod, support and truss support the role of supporting the steel beam and the steel column, and the angle steel, round steel and steel pipe used are relatively large.
Roof and wall
Roof and wall maintenance systems can be used with single laminate panels and composite panels.
Small accessories can be wrapped with color plates to wrap the corners.
Doors and windows
Aluminum alloy and plastic steel are the first choice.
