Industrial Steel Buildings Technical Performance

Smartweigh Instrument Co.,Ltd | Updated: Sep 18, 2017

Industrial steel structure is composed of steel material structure, is one of the main building structure type. The structure is mainly composed of steel and steel plate, steel column, steel truss and other components, the components or components are usually used between the weld, bolt or rivet connection. Because of its relatively light weight, and the construction is simple, widely used in large factories, venues, high-level areas.


1, the material strength is high, its own light weight

Steel strength is high, elastic modulus is also high. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so under the same stress conditions, the steel structure of the small cross-section, light weight, easy to transport and installation, suitable for large span, high height, Structure.

2, steel toughness, good plasticity, uniform material, high structural reliability

Suitable for impact and dynamic load, with good seismic performance. The internal structure of the steel is uniform and is close to the isotropic homogeneous body. The actual working performance of steel structure is more consistent with the calculation theory. So the steel structure is highly reliable.

3, steel construction and installation of a high degree of mechanization

The steel structure is easy to manufacture in the factory, site assembly. Factory mechanized steel structure components of high precision, high production efficiency, site assembly fast, short duration. Steel structure is the highest degree of industrialization of a structure.

4, steel structure sealing performance

As the welding structure can be completely sealed, can be made airtight, watertight are good high-pressure containers, large oil pools, pressure pipes and so on.

5, steel heat is not refractory

When the temperature below 150 ℃, the steel properties change is very small. So the steel structure for the hot workshop, but the structural surface of about 150 ℃ by the heat radiation, to be used to protect the insulation board. The temperature of 300 ℃ -400 ℃. Steel strength and elastic modulus were significantly decreased, the temperature at about 600 ℃, the strength of steel tends to zero. In buildings with special fire protection requirements, the steel structure must be protected with refractory material to improve the fire rating.

6, steel corrosion resistance is poor

Especially in wet and corrosive media environment, easy to rust. General steel structure to rust, galvanized or paint, and to regular maintenance. On the seawater in the offshore platform structure, the use of "zinc block anode protection" and other special measures to be anti-corrosion.

7, low carbon, energy saving, green, reusable

Steel construction demolition almost no construction waste, steel can be recycled.

Technical performance

Thermal insulation technology Light steel structure In order to ensure the effect of insulation, insulation and insulation materials used in the external walls and roofs of buildings can be used for a long time and can be insulated. Building light steel structure in general, in addition to the wall of the wall filled with glass fiber mesh, the wall and then paste a layer of insulation material, effectively cut off through the wall to the outer wall of the bridge; Filled with glass fiber, to reduce the heat transfer through the floor; all walls of the wall between the wall are filled with glass fiber, reducing the heat transfer between the wall.

Fire protection technology Light steel structure One of the most critical issues is the application of fire protection technology, light steel structure residential fire rating of four. Construction of light steel structure on both sides of the wall and the floor of the ceiling of the fire paste plaster board, for the ordinary firewall and wall with 25.4 mm thick (1 inch) gypsum board protection to achieve 1 hour fire protection requirements, the other Fiberglass filled between wall studs and floor grills also has a positive protection against fire and heat transfer.

Sound insulation technology Light steel structure Inside the outer wall and floor joists Fill glass wool, effectively prevent the air through the audio part of the transmission, and for the impact of solid transmission through the sound, the following structure: for the wall with two The pillars form a two-walled wall with an intermediate gap; and for the small keel of the fixed gypsum board for the ceiling, the elastic structure with a small chute is used to effectively reduce the solid sound propagation between the floors.
