輕型鋼結構的概念

The concept of lightweight steel structures

輕型鋼結構通常指由圓鋼、小角鋼、薄壁型鋼或薄鋼板焊接而成的結構，這是一個相對的概念，以區別往常的普通鋼結構。普通鋼結構一般由鋼屋架、組合柱（H型鋼、鋼管、槽鋼等）和大噸位吊車梁等組成，適應于荷載或吊車起重量較大的結構，以及有較大振動和有抗震要求的結構。隨著國民經濟的產業結構調整，普通鋼結構逐漸減少，而輕型實腹梁、實腹柱及小噸位吊車梁等逐漸增加。

Light steel structures usually refer to structures welded from round steel, small angle steel, thin-walled steel or thin steel plates, which is a relative concept to distinguish from ordinary steel structures. Ordinary steel structures are generally composed of steel roof trusses, composite columns (H-shaped steel, steel pipes, channel steel, etc.), and large-tonnage crane beams. They are suitable for structures with large loads or crane lifting capacity, as well as structures with significant vibration and seismic requirements. With the adjustment of the industrial structure of the national economy, ordinary steel structures are gradually decreasing, while lightweight solid web beams, solid web columns, and small tonnage crane beams are gradually increasing.

用鋼量省，節省投資：

Saving steel consumption and investment:

輕型鋼屋面系統的用鋼量一般為8~15kg/m2，單層輕鋼倉庫的用鋼量為16~30kg/m2.接近甚可低于在相同條件鋼筋混凝土結構的用鋼量，且能節約大量木材、水泥及其它建筑材料。因此輕鋼結構可大幅度降低結構自重，一般約為普通鋼結構的1/2~1/3，鋼筋混凝土的1/10~3/10.比傳統的鋼筋混凝土結構及普通鋼結構節省建設資金。

The steel consumption of light steel roof systems is generally 8-15kg/m2, while the steel consumption of single-layer light steel warehouses is 16-30kg/m2. It is close to or even lower than the steel consumption of reinforced concrete structures under the same conditions, and can save a lot of wood, cement, and other building materials. Therefore, lightweight steel structures can significantly reduce the self weight of the structure, which is generally about 1/2-1/3 of that of ordinary steel structures and 1/10-3/10 of that of reinforced concrete. This saves construction funds compared to traditional reinforced concrete structures and ordinary steel structures.

防止滲漏，效果理想：

To prevent leakage and achieve ideal results:

輕型鋼結構的屋面及墻面材料主要選用彩色壓型板或夾芯板，檁條為自重較輕的薄壁C型或Z型鋼檁條。輕型鋼結構廠房的屋面坡度設計一般為1/10~1/15，屋面壓型鋼板可靠連接后，固定于鋼檫條上。雨水可順壓型板直接排內外天溝，通過硬質塑料PVC管迅速排下水管或室外的水溝，確保廠房防雨水滲漏的要求。

The roof and wall materials of lightweight steel structures mainly use colored profiled panels or sandwich panels, and the purlins are thin-walled C-shaped or Z-shaped steel purlins with relatively light self weight. The roof slope design of light steel structure factories is generally 1/10-1/15, and the roof profiled steel plates are reliably connected and fixed on steel strips. Rainwater can be directly discharged into the internal and external gutters along the pressure plate, and quickly discharged into the sewer pipe or outdoor ditch through hard plastic PVC pipes to ensure the requirements for preventing rainwater leakage in the factory.

無需打樁，縮短工期：

No need for pile driving, shortened construction period:

輕型鋼結構廠房因其自重輕，一般僅需采用柱下混凝土基礎即可滿足承載要求。由此，縮短了建設周期，節省建設投資。

Light steel structure factory buildings, due to their light weight, generally only require the use of concrete foundations under columns to meet the bearing requirements. As a result, the construction cycle is shortened and construction investment is saved.

供貨迅捷，安裝方便：

Fast supply and easy installation:

輕型鋼結構所用材料均為常規用料。其圍護系統所用壓型板及配件，以及C型和Z型鋼檁條的生產廠家也非常多，一般，一座1萬m2左右的單層廠房或倉庫從設計開始到交付使用僅需3~4個月的時間，可比鋼筋混凝土結構的廠房縮短工期一半甚更多。

The materials used for lightweight steel structures are all conventional materials. There are also many manufacturers of profiled plates and accessories used in its enclosure system, as well as C-shaped and Z-shaped steel purlins. Generally, a single-story factory or warehouse with an area of about 10000 square meters only takes 3-4 months from design to delivery, which can shorten the construction period by half or even more than a reinforced concrete structure factory.

輕型鋼結構廠房或倉庫顏色根據需要選擇，任意調整，隨意組合。屋面壓型板，尤其是墻面彩色壓型板，具有輕質、、色彩艷麗、造型美觀的特點。它除主要作為墻體用外，也具有裝飾面板的作用。您有需求就來我們網站http://m.gitli.cn咨詢了解吧！

The color of light steel structure factories or warehouses can be selected according to needs, adjusted and combined at will. Roof profiled panels, especially wall colored profiled panels, have the characteristics of lightweight, efficient, colorful, and aesthetically pleasing appearance. It not only serves as a wall, but also serves as a decorative panel. Come to our website if you have any needs http://m.gitli.cn Consult and understand!
