濟(jì)南輕型鋼結(jié)構(gòu)具有良好的力學(xué)性能和綜合經(jīng)濟(jì)效益,其特點(diǎn)主要表現(xiàn)在
Light steel structure has good mechanical properties and comprehensive economic benefits
1.自重輕
1. Light weight
自重輕是輕型鋼結(jié)構(gòu)顯著的特點(diǎn)。輕型鋼結(jié)構(gòu)的承重構(gòu)件主要采用輕型焊接H型鋼、高頻焊接型鋼、輕型熱軋型鋼、冷彎薄壁型鋼等截面形式,這些型鋼截面比普通的工的情況下,輕型鋼結(jié)構(gòu)比普通鋼結(jié)構(gòu)節(jié)約鋼材30%以上。一般單層輕型鋼結(jié)構(gòu)廠房用鋼量為20~40kg/m2,采用冷彎薄壁型鋼的輕鋼屋架用鋼量為15kg/m2以下,輕型鋼結(jié)構(gòu)房屋的圍護(hù)結(jié)構(gòu)采用輕質(zhì)材料,圍護(hù)結(jié)構(gòu)和主體承重結(jié)構(gòu)自重均較輕,結(jié)構(gòu)基礎(chǔ)形式簡單且費(fèi)用低。
Light weight is a significant feature of light steel structure. The load-bearing members of light steel structure mainly adopt light welded H-section steel, high-frequency welding section steel, light hot-rolled section steel, cold-formed thin-walled steel and other cross-section forms. Under the condition of these steel sections, the light-weight steel structure can save more than 30% steel than the ordinary steel structure. Generally, the steel consumption of single storey light steel structure workshop is 20 ~ 40kg / m2, and the steel consumption of light steel roof truss using cold-formed thin-walled steel is less than 15kg / m2. The enclosure structure of light-weight steel structure building adopts light material, the weight of enclosure structure and main bearing structure is light, and the structure foundation form is simple and low-cost.

2.抗震性能好
2. Good seismic performance
輕型鋼結(jié)構(gòu)的鋼材具有材質(zhì)均勻、強(qiáng)度高、彈塑性性能好,承受動(dòng)載能力強(qiáng),可靠性高,構(gòu)件破壞前有較大的塑性變形。此外,輕型鋼結(jié)構(gòu)自重輕,結(jié)構(gòu)的地震作用顯著減小,結(jié)構(gòu)整體抗震性能強(qiáng)。對(duì)于單層或低層輕型鋼結(jié)構(gòu),地震作用通常不起控制作用。比如單層門式剛架結(jié)構(gòu),一般情況下可以不做抗震驗(yàn)算。
The steel of light steel structure has uniform material, high strength, good elastic-plastic performance, strong bearing capacity of dynamic load, high reliability, and large plastic deformation before failure. In addition, the light steel structure has light weight, the seismic action of the structure is significantly reduced, and the overall seismic performance of the structure is strong. For single-layer or low-rise light-weight steel structures, seismic action usually does not play a controlling role. For example, the single-layer portal frame structure, generally can not do seismic checking calculation.
3.裝配率高,施工周期短
3. High assembly rate and short construction period
輕型鋼結(jié)構(gòu)的建筑構(gòu)造簡單,所用材料為常規(guī)材料,主要構(gòu)件和配件均為工廠工業(yè)化制作,構(gòu)件加工精度高。構(gòu)件自重輕,運(yùn)輸安裝便利,無須大型機(jī)械設(shè)備,工地現(xiàn)場安裝方便。除基礎(chǔ)施工外,基本沒有濕作業(yè),構(gòu)件之間多采用螺栓連接,現(xiàn)場施工人員少,與同規(guī)模的鋼筋混凝土結(jié)構(gòu)相比,輕型鋼結(jié)構(gòu)施工工期可縮短1/3左右。
The light-weight steel structure is simple in construction, the materials used are conventional materials, the main components and accessories are factory industrialized production, and the component processing accuracy is high. It has the advantages of light weight, convenient transportation and installation, no need of large-scale mechanical equipment, and convenient installation on site. In addition to the foundation construction, there is basically no wet operation, the components are mostly connected by bolts, and the site construction personnel are less. 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.綜合經(jīng)濟(jì)效益好
4. Good comprehensive economic benefits
輕型鋼結(jié)構(gòu)構(gòu)件斷面小,可減小結(jié)構(gòu)本身在建筑面積上的占比。同時(shí),也可在一定程度上降低結(jié)構(gòu)層高,增加建筑有效使用面積。項(xiàng)目施工周期短,極大地減少投資成本,發(fā)揮提前使用的效益,率快。輕型鋼結(jié)構(gòu)施工主要為千法作業(yè),有利于文明施工,建筑廢料少。
The light steel structure component section is small, which can reduce the proportion of the structure itself in the building 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 of using in advance is brought into play, and the rate of return on investment is fast. Light steel structure construction is mainly a thousand methods of operation, conducive to civilized construction, less construction waste.
