轻量化是轻钢结构最突出的特点。轻钢结构的承重构件主要采用轻焊h型钢、高频焊型钢、轻热轧型钢、冷弯薄壁型钢等截面形式。在这些截面比普通截面多的情况下,轻钢结构比普通钢结构节省钢材30%以上。单层轻钢结构厂房用钢量一般为20~40kg/m2,冷弯薄壁钢轻钢屋面框架用钢量一般小于15kg/m2。轻钢结构房屋的围护结构采用轻质材料。围护结构与主体承重结构均轻,结构基础形式简单,造价低。
  Lightweight is the most prominent feature of light steel structure. The main load-bearing members of light steel structure are light welded H-beam, high frequency welded beam, light hot rolled beam and cold-formed thin-walled beam. In the case that these sections are more than ordinary sections, the steel of light steel structure is more than 30% less than ordinary steel structure. The steel consumption of single-layer light steel structure workshop is generally 20 ~ 40kg / m2, and that of cold-formed thin-walled steel light steel roof frame is generally less than 15kg / m2. The enclosure structure of light steel structure house adopts light material. The envelope structure and the main bearing structure are light, the structure foundation form is simple, and the cost is low.
  2. 良好的抗震性能
  2. Good seismic performance
  轻钢结构钢具有材料均匀、强度高、弹塑性性能好、动载能力强、可靠性高、构件失效前塑性变形大等特点。此外,轻钢结构自重轻,结构抗震效果明显降低,结构整体抗震性能强。对于单层或低层的轻型钢结构,地震作用通常不受控制。例如,单层门式刚架结构,一般不能做抗震验算。
  Light steel structural steel has the characteristics of uniform material, high strength, good elastic-plastic performance, strong dynamic load capacity, high reliability and large plastic deformation before component failure. In addition, the self weight of the light steel structure is light, the seismic effect of the structure is significantly reduced, and the overall seismic performance of the structure is strong. For single story or low story light steel structure, seismic action is usually not controlled. For example, the single-layer portal frame structure, generally can not do seismic checking calculation.
  3.装配率高,工期短
  3. High assembly rate and short construction period
  轻型钢结构的建筑结构简单,采用常规材料,主要零部件及配件均为工厂工业化生产,零部件加工精度高。组件自重轻,运输安装方便,无需大型机械设备,现场安装方便。除基础施工外,基本无湿工,构件间多采用螺栓连接,现场施工人员较少。与同规模的钢筋混凝土结构相比,轻钢结构的工期可缩短约1/3。
  The building structure of light steel structure is simple, using conventional materials, and the main parts and accessories are industrialized production in the factory with high processing accuracy. The component has light weight, convenient transportation and installation, no need of large mechanical equipment, and convenient on-site installation. In addition to foundation construction, there is basically no wet work, and the members are mostly connected by bolts, with few on-site construction personnel. Compared with the reinforced concrete structure of the same scale, the construction period of light steel structure can be shortened by about 1 / 3.

  4. 综合经济效益好
  4. Good comprehensive economic benefits
  轻钢结构构件截面小,可减少结构本身在施工面积中的比例。同时也可以在一定程度上降低结构的高度,增加建筑的有效利用面积。项目建设周期短,大大降低了投资成本,发挥了效益,使用早,投资回报快。轻钢结构的施工主要是千次作业,有利于文明施工,减少建筑浪费。
  The small section of light steel structure can reduce the proportion of structure in construction area. At the same time, it can also reduce the height of the structure to a certain extent and increase the effective use area of the building. The construction period of the project is short, the investment cost is greatly reduced, the benefit is brought into play, the use is early, and the investment return is fast. The construction of light steel structure mainly involves thousands of operations, which is conducive to civilized construction and reduces construction waste.
  5. 节能环保
  5. Energy conservation and environmental protection
  轻钢结构的墙体重量轻、保温隔热、隔音性能优于传统墙体材料,符合建筑节能环保要求,可达到节能50%的目标,节约人均资源相对不足。轻质墙体材料为不燃阻燃材料,耐火时限可达1h以上。建筑装修、围护采取防火措施(防火板罩或防火涂料)后耐火时限可达2.5h。大部分建筑结构材料都可以回收再利用,节约了大量资源,有利于环境保护。属于“绿色建筑”,符合国家可持续发展政策和环保要求
  The wall of light steel structure is light in weight, superior to traditional wall materials in heat preservation, heat insulation and sound insulation. It meets the requirements of building energy conservation and environmental protection, and can achieve the goal of 50% energy conservation. The per capita resource conservation is relatively insufficient. The light wall material is nonflammable and flame retardant, and the fire resistance time can be more than 1h. The fire resistance time limit of building decoration and enclosure can reach 2.5h after taking fire prevention measures (fire-proof board cover or fire-proof coating). Most of the building structural materials can be recycled, which saves a lot of resources and is conducive to environmental protection. It belongs to "green building" and conforms to the national sustainable development policy and environmental protection requirements
