轻型钢结构的应用日益广泛，其数量也日渐增多，各方面的原因也给了轻型钢结构的发展注人了活力，其结构技术也得到了较好的完善。下面就来讲讲济南轻型钢结构的概念以及结构特点内容吧。

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.

轻型钢结构的概念

Concept of light steel structure

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 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.

用钢量省，节省投资：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。

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.

防止渗漏，效果理想：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内外天沟，通过硬质塑料PVC管迅速排下水管或室外的水沟，确保厂房防雨水渗漏的要求。

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.

无需打桩，缩短工期：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。

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.

供货迅捷，安装方便：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。您有需求就来我们网站http://www.jnghbxg.com咨询吧！

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.
