輕型鋼結構的應用日益廣泛，其數量也日漸增多，各方面的原因也給了輕型鋼結構的發展注人了活力，其結構技術也得到了較好的完善。下面就來講講濟南輕型鋼結構的概念以及結構特點內容吧。

The application of light steel structure is increasingly widespread, and its number is also increasing. Various reasons have also given vitality to the development of light steel structure, and its structural technology has also been better improved. Now let's talk about the concept and structural characteristics of Jinan light steel structure.

輕型鋼結構的概念

Concept of light steel structure

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 structure usually refers to the structure welded by round steel, small angle steel, thin-walled section steel or thin steel plate, which is a relative concept to distinguish the ordinary steel structure. 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, which are suitable for structures with large load or crane lifting capacity, as well as structures with large vibration and seismic requirements. With the adjustment of the industrial structure of the national economy, ordinary steel structures are gradually reduced, while light solid web beams, solid web columns and small tonnage crane beams are gradually increased.

用鋼量省，節省投資：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。

Save steel consumption and investment: the steel consumption of light steel roof system is generally 8~15kg/m2, and the steel consumption of single-layer light steel warehouse is 16~30kg/m2. It is close to or even lower than the steel consumption of reinforced concrete structure under the same conditions, and can save a lot of wood, cement and other building materials. Therefore, the light steel structure can greatly reduce the dead weight of the structure, which is generally about 1/2~1/3 of the ordinary steel structure, and 1/10~3/10 of the reinforced concrete. Compared with the traditional reinforced concrete structure and ordinary steel structure, the light steel structure can save construction funds.

防止滲漏，效果理想：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 effect of preventing leakage is ideal: the roof and wall materials of light steel structure mainly use color profiled plates or sandwich panels, and purlins are thin-walled C or Z steel purlins with light weight. The roof slope design of light steel structure workshop is generally 1/10~1/15, and the roof profiled steel plate is fixed on the steel sash after reliable connection. The rainwater can be directly drained to the internal and external gutter along the profiled plate, and quickly drained to the sewer pipe or the outdoor gutter through rigid plastic PVC pipe to ensure the requirements of the plant to prevent rainwater leakage.

無需打樁，縮短工期：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。

There is no need to drive piles and shorten the construction period: because of its light weight, the light steel structure plant can generally meet the bearing requirements only by using the concrete foundation under the column. Thus, the construction period is shortened and the construction investment is saved.

供貨迅捷，安裝方便：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。

Fast supply and convenient installation: all materials used for light steel structure are conventional materials. There are also many manufacturers of profiled plates and accessories used in its enclosure system, as well as C-type and Z-type steel purlins. Generally, a single-storey factory building or warehouse with an area of about 10000 m2 only takes 3 to 4 months from design to delivery, which can shorten the construction period by half or more than that of a factory building with reinforced concrete structure.

此外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。您有需求就來我們網站http://m.gitli.cn咨詢吧！

In addition, the color of light steel structure workshop or warehouse can be selected, adjusted and combined as required. The roof profiled panel, especially the wall color profiled panel, has the characteristics of light weight, bright color and beautiful shape. Come to our website if you need http://m.gitli.cn Ask!
