Light steel structure which means light steel structure building system is composed of a high performance structural steel and high performance functional material and the decorative connecting material composition. The high performance structural steel and high performance functional material is like H light steel, light steel welding, high frequency welding steel, cold-formed steel, thin steel plate and the thin wall steel tube, etc. Besides, Light steel structure can meet the demand of architecture specific functions and specific space.

《钢结构设计规范》GB50017-2003

轻钢结构即轻型钢结构建筑体系,是以热轧轻型H钢、轻型焊接型钢、高频焊接型钢、冷弯薄壁型钢、薄钢板和薄壁钢管等高效能结构钢材和高效功能材料为主,以各类高效装饰连接材料为辅组装而成,能满足建筑特定使用功能和特定空间需求的轻型全装配钢结构建筑。

In fact, Both heavy steel structure and light steel structure has not unified definition. There are Many experienced designer or project manager who also can"t make it sense, but we can distinguish them by referencing some date.

One, Lifting weight of workshop crane lifting weight: if the weight is greater than or equal to 25 tons, this building can be thought of as heavy steel structure.

Two, The amount of steel per unit area: if the amount is greater than or equal to 50KG/M2, this building can be considered to be heavy steel structure.

Three, the thickness of the main steel component: if the thickness is greater than or equal to 10MM, this building can be considered to be heavy steel structure.

判定结构为重钢与轻钢结构确实没有一个统一的标准,很多有经验的设计师或项目经理也常常不能完全说明白,但我们可以以一些数据综合考虑并加以判断:

1、厂房行车起吊重量:大于等于25吨,可以认为为重钢结构了。

2、每平米用钢量:大于等于50KG/M2,可认为是重钢结构。

3、主要构件钢板厚度:大于等于10MM,轻钢结构用的较少。

网架(Space frame)

In architecture and structural engineering, a space frame or space structure is a truss-like, lightweight rigid structure constructed from interlocking struts in a geometric pattern. Space frames can be used to span large areas with few interior supports. Like the truss, a space frame is strong because of the inherent rigidity of the triangle; flexing loads (bending moments) are transmitted as tension and compression loads along the length of each strut.

The simplest form of space frame is a horizontal slab of interlocking square pyramids and tetrahedra built from aluminium or tubular steel struts. In many ways this looks like the horizontal jib of a tower crane repeated many times to make it wider. A stronger form is composed of interlocking tetrahedra in which all the struts have unit length. More technically this is referred to as an isotropic vector matrix or in a single unit width an octet truss. More complex variations change the lengths of the struts to curve the overall structure or may incorporate other geometrical shapes.

管桁架(Pipe Truss)

Pipe truss refers to one grid type structure connected by round rod. Using round rod makes this structure has good material economic and reduce it’s weight. Besides, using round rod makes the structure easy to form various shapes so as to adapt to different application, such like simply supported girder, arch, framework, tower, etc.

In recent years, with the growing of China"s steel production, pipe truss is widely used and the proportion in the construction gets bigger, such like industrial plant, automobile and other industries production line equipment platform, logistics, warehousing, public buildings gymnasium, business center, high-speed rail station, subway station, high-rise commercial buildings, etc.

管桁架,是指用圆杆件在端部相互连接而组成的格子式结构。圆杆件使桁架结构用料经济、结构自重轻,易于构成各种外形以适应不同的用途,譬如可以做成简支桁架、拱、框架及塔架等。 近年来,随着我国钢铁产量的不断增长,管桁架在被越来越广泛的使用,在建筑中所占的比例越来越大,工业厂房、汽车等行业设备平台生产线、物流仓储、公共建筑体育馆、商务会所、高铁站台、地铁站台、高层商务楼等得到广泛应用。
