轻型钢结构的概念

The concept of lightweight steel structures

轻型钢结构通常指由圆钢、小角钢、薄壁型钢或薄钢板焊接而成的结构，这是一个相对的概念，以区别往常的普通钢结构。普通钢结构一般由钢屋架、组合柱（H型钢、钢管、槽钢等）和大吨位吊车梁等组成，适应于荷载或吊车起重量较大的结构，以及有较大振动和有抗震要求的结构。随着国民经济的产业结构调整，普通钢结构逐渐减少，而轻型实腹梁、实腹柱及小吨位吊车梁等逐渐增加。

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.

Structural Characteristics of Jinan Light Steel Structures

用钢量省，节省投资：

Saving steel consumption and investment:

轻型钢屋面系统的用钢量一般为8~15kg/m2，单层轻钢仓库的用钢量为16~30kg/m2.接近甚至可低于在相同条件钢筋混凝土结构的用钢量，且能节约大量木材、水泥及其它建筑材料。因此轻钢结构可大幅度降低结构自重，一般约为普通钢结构的1/2~1/3，钢筋混凝土的1/10~3/10.比传统的钢筋混凝土结构及普通钢结构节省建设资金。

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.

防止渗漏，效果理想：

To prevent leakage and achieve ideal results:

轻型钢结构的屋面及墙面材料主要选用彩色压型板或夹芯板，檩条为自重较轻的薄壁C型或Z型钢檩条。轻型钢结构厂房的屋面坡度设计一般为1/10~1/15，屋面压型钢板可靠连接后，固定于钢檫条上。雨水可顺压型板直接排至内外天沟，通过硬质塑料PVC管迅速排至下水管或室外的水沟，确保厂房防雨水渗漏的要求。

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.

无需打桩，缩短工期：

No need for pile driving, shortened construction period:

轻型钢结构厂房因其自重轻，一般仅需采用柱下混凝土基础即可满足承载要求。由此，缩短了建设周期，节省建设投资。

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.

供货迅捷，安装方便：

Fast supply and easy installation:

轻型钢结构所用材料均为常规用料。其围护系统所用压型板及配件，以及C型和Z型钢檩条的生产厂家也非常多，一般，一座1万m2左右的单层厂房或仓库从设计开始到交付使用仅需3~4个月的时间，可比钢筋混凝土结构的厂房缩短工期一半甚至更多。

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.

轻型钢结构厂房或仓库颜色根据需要选择，任意调整，随意组合。屋面压型板，尤其是墙面彩色压型板，具有轻质、、色彩艳丽、造型美观的特点。它除主要作为墙体用外，也具有装饰面板的作用。您有需求就来我们网站http://www.jnghbxg.com咨询了解吧！

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://www.jnghbxg.com Consult and understand!
