　　四、 輕鋼住宅體系七大優(yōu)勢1.安全

　　4、 Seven advantages of light steel residential system: 1. Safety

　　與木結(jié)構(gòu)建筑相比，鋼結(jié)構(gòu)建筑防火性能和防白蟻性能大大優(yōu)于木結(jié)構(gòu)建筑。超輕鋼結(jié)構(gòu)形式建筑在北美的出現(xiàn)和發(fā)展很大原因是因?yàn)槟窘Y(jié)構(gòu)自身的防火性能和防白蟻性能較差，因此在輕型木結(jié)構(gòu)基礎(chǔ)上發(fā)展了超輕鋼結(jié)構(gòu)體系。

　　Compared with wooden structures, steel structures have significantly better fire and termite resistance. The emergence and development of ultra light steel structure buildings in North America are largely due to the poor fire and termite resistance of wooden structures. Therefore, ultra light steel structure systems have been developed on the basis of lightweight wooden structures.

　　與傳統(tǒng)磚混結(jié)構(gòu)相比，鋼結(jié)構(gòu)體系本身較磚混結(jié)構(gòu)更具延展性和彈性。超輕鋼結(jié)構(gòu)屬于板肋結(jié)構(gòu)體系，它由輕鋼龍骨和歐松板形成的墻體、樓板作為承重結(jié)構(gòu)，屬于超靜定結(jié)構(gòu)體系，單根輕鋼龍骨或歐松板的破壞不會立即導(dǎo)致整體結(jié)構(gòu)的破壞，有利于建筑物內(nèi)人員逃生。同時自重輕的鋼結(jié)構(gòu)建筑更有利于抵抗地震時的水平荷載（水平荷載為建筑物自重和水平加速度的乘積，質(zhì)量越小的建筑物承受的水平荷載越小）。所以在地震多發(fā)區(qū)域的日本和臺灣，低層建筑多為自重較輕的輕型木結(jié)構(gòu)和鋼結(jié)構(gòu)建筑。

　　Compared with traditional brick and concrete structures, steel structure systems themselves have more ductility and elasticity than brick and concrete structures. Ultra light steel structure belongs to the plate rib structure system, which is composed of walls and floors formed by light steel keel and European pine board as load-bearing structures. It belongs to the ultra static structural system, and the damage of a single light steel keel or European pine board will not immediately cause the overall structure to be destroyed, which is conducive to the escape of personnel inside the building. Steel structure buildings with light self weight are more conducive to resisting horizontal loads during earthquakes (horizontal loads are the product of the building's self weight and horizontal acceleration, with smaller buildings bearing smaller horizontal loads). So in earthquake prone areas such as Japan and Taiwan, low rise buildings are mostly lightweight wooden and steel structures.

　　2.方便與傳統(tǒng)磚混結(jié)構(gòu)相比，自重輕的鋼結(jié)構(gòu)建筑的運(yùn)輸量小于磚混結(jié)構(gòu)。利于在運(yùn)輸不便的區(qū)域如島嶼、山區(qū)建造。超輕鋼建筑還可以根據(jù)項(xiàng)目需要在工廠完成部分拼裝任務(wù)，形成整片墻體和樓板，減少現(xiàn)場作業(yè)量，加快現(xiàn)場安裝速度，適用于當(dāng)?shù)厥┕l件惡劣，施工周期較短的項(xiàng)目。

　　2. Compared with traditional brick and concrete structures, the transportation volume of lightweight steel structure buildings is smaller than that of brick and concrete structures. Beneficial for construction in areas with inconvenient transportation, such as islands and mountainous regions. Ultra light steel buildings can also complete partial assembly tasks in the factory according to project needs, forming whole walls and floors, reducing on-site workload, accelerating on-site installation speed, and suitable for projects with harsh local construction conditions and short construction periods.

　　3.環(huán)保

　　3. Environmental Protection

　　輕鋼住宅體系產(chǎn)品所采用的建筑材料均為符合國家標(biāo)準(zhǔn)的綠色環(huán)保材料，所用輕鋼龍骨70年后仍可回收利用，現(xiàn)場建造過程中大量使用成品構(gòu)件安裝，建造用水需求量小，整個建造過程比磚混結(jié)構(gòu)大大減少廢水、廢塵和固體廢棄物的排放，有利于當(dāng)?shù)丨h(huán)境的保護(hù)。輕鋼住宅體系建造過程中材料損耗減少60%，現(xiàn)場垃圾減少80%，可回收材料占80%，建筑節(jié)能提高50%。

　　The building materials used in the light steel residential system products are all green and environmentally friendly materials that meet national standards. The light steel keel used can still be recycled after 70 years. During the on-site construction process, a large number of finished components are used for installation, and the construction water demand is small. The entire construction process greatly reduces the discharge of wastewater, dust, and solid waste compared to brick and concrete structures, which is conducive to the protection of the local environment. During the construction process of the light steel residential system, material loss is reduced by 60%, on-site waste is reduced by 80%, recyclable materials account for 80%, and building energy efficiency is increased by 50%.

　　4.節(jié)能輕鋼住宅體系外墻采用雙層保溫結(jié)構(gòu)，由內(nèi)向外分別為：石膏板、輕鋼龍骨、R19離心玻璃纖維棉、OSB（歐松板）、呼吸紙、擠塑板和外墻飾面層。由于墻體采用R19離心玻璃纖維棉和25mm厚擠塑板雙層保溫材料，墻體系統(tǒng)的熱阻值可達(dá)到為4.24K?㎡/W，其保溫隔熱性能是490mm厚多孔砌塊磚墻體的2倍。建筑屋蓋由內(nèi)向外分別為：石膏板、R30離心玻璃纖維棉、輕鋼龍骨、OSB（歐松板）、防水卷材和屋面裝飾層。封檐板為多孔構(gòu)造，使整個屋架通風(fēng)透氣，流通的空氣既可防霉也可起到保溫隔熱的作用，整個屋蓋系統(tǒng)熱阻值為5.284K?㎡/W，是普通120mm厚混凝土屋頂（熱阻值為0.07K?㎡/W ）的75倍。

　　4. The exterior wall of the energy-saving light steel residential system adopts a double-layer insulation structure, which consists of gypsum board, light steel keel, R19 centrifugal glass fiber cotton, OSB (European pine board), breathing paper, extruded board, and exterior wall decorative layer from inside to outside. Due to the use of R19 centrifugal glass fiber cotton and 25mm thick extruded polystyrene board double-layer insulation material in the wall system, the thermal resistance value of the wall system can reach 4.24K? ㎡/W, and its insulation performance is twice that of 490mm thick porous brick walls. The building roof is composed of gypsum board, R30 centrifugal glass fiber cotton, light steel keel, OSB (European pine board), waterproofing membrane, and roof decoration layer from inside to outside. The eaves panel is a porous structure that allows the entire roof truss to be ventilated and breathable. The circulating air can not only prevent mold but also provide insulation. The thermal resistance value of the entire roof system is 5.284K? ㎡/W, which is 75 times that of a regular 120mm thick concrete roof (with a thermal resistance value of 0.07K? ㎡/W).

　　5.實(shí)用

　　5. Practical

　　輕鋼住宅體系雙層保溫裝飾外墻厚度僅為180mm，比一般不含保溫裝飾的磚混結(jié)構(gòu)墻體（一般為240mm）還要小60mm.

　　The thickness of the double-layer insulation decoration exterior wall of the light steel residential system is only 180mm, which is 60mm smaller than the general brick and concrete structure wall without insulation decoration (usually 240mm)

　　根據(jù)所做項(xiàng)目測算，輕鋼住宅體系的得房率比普通磚混結(jié)構(gòu)要提高5%-10%。同時由于輕鋼結(jié)構(gòu)體系采用墻板和樓板受力而非傳統(tǒng)的梁柱受力，所以輕鋼建筑室內(nèi)幾乎無梁無柱，空間利用更高。

　　According to the project calculations, the yield of light steel residential systems is 5% -10% higher than that of ordinary brick and concrete structures. At the same time, due to the use of wall panels and floor slabs instead of traditional beam column loads in the light steel structure system, there are almost no beams or columns in the interior of light steel buildings, resulting in higher space utilization.

　　6.快捷

　　6. Quick and efficient

　　輕鋼住宅體系采用工廠加工構(gòu)件，現(xiàn)場拼裝，無需養(yǎng)護(hù)，所以施工速度比普通磚混結(jié)構(gòu)要提高30%-50%。整個施工流程分：基礎(chǔ)施工、墻體安裝、屋頂安裝、結(jié)構(gòu)封板、外墻保溫、室內(nèi)裝飾、室外裝飾和完工交房八大步驟。不含基礎(chǔ)施工的毛坯房施工周期為1-2個月，精裝修房施工周期為2-3個月。一套100平方米的超輕鋼主體結(jié)構(gòu)安裝時間只需4-5天，整體施工周期比傳統(tǒng)建筑至少縮減1/2的時間。

　　The light steel residential system adopts factory processed components, on-site assembly, and does not require maintenance, so the construction speed is 30% -50% faster than ordinary brick and concrete structures. The entire construction process is divided into eight steps: foundation construction, wall installation, roof installation, structural sealing, external wall insulation, indoor decoration, outdoor decoration, and completion and handover. The construction period for rough houses without foundation construction is 1-2 months, and the construction period for fine decoration houses is 2-3 months. A 100 square meter ultra light steel main structure can be installed in just 4-5 days, reducing the overall construction period by at least half compared to traditional buildings.

　　7.綜合經(jīng)濟(jì)效益好

　　7. Good comprehensive economic benefits

　　A.施工周期短，早投產(chǎn)早得益；B.有效使用面積增加；C.投資使用分配合理，價符其值；地上與地下工程費(fèi)分配90:10；D.材料與人工費(fèi)分配?60:40；因此輕鋼住宅體系綜合經(jīng)濟(jì)效益優(yōu)于鋼筋混凝土結(jié)構(gòu)。

　　A. Short construction period, early production and benefits; B. Increase in effective usage area; C. Reasonable allocation of investment use and value matching; Distribution of above ground and underground engineering costs 90:10; D. What is the allocation of material and labor costs? 60:40； Therefore, the comprehensive economic benefits of light steel residential systems are superior to those of reinforced concrete structures.

　　六、超輕鋼主體結(jié)構(gòu)性能1.鋼材的選用用于低層冷彎薄壁型鋼房屋承重結(jié)構(gòu)的冷彎薄壁型鋼, 應(yīng)采用現(xiàn)行國家標(biāo)準(zhǔn)《碳素結(jié)構(gòu)鋼》GB/T700、《低合金高強(qiáng)度結(jié)構(gòu)鋼》GB/T1591 規(guī)定的Q235、Q345 ，以及滿足現(xiàn)行國家標(biāo)準(zhǔn)《連續(xù)熱鍍鋅鋼板及鋼帶》GB/T 2518、《連續(xù)熱鍍鋁鋅合金鍍層鋼板及鋼帶》GB/T14978 要求的Q550 級鋼材。

　　6、 Performance of Ultra Light Steel Main Structure 1. Selection of Steel: Cold formed thin-walled steel used for load-bearing structures of low rise cold-formed thin-walled steel buildings should use Q235 and Q345 specified in the current national standards "Carbon Structural Steel" GB/T700 and "Low alloy High strength Structural Steel" GB/T1591, as well as Q550 grade steel that meets the requirements of the current national standards "Continuous Hot dip Galvanized Steel Plate and Strip" GB/T 2518 and "Continuous Hot dip Aluminum Zinc Alloy Coated Steel Plate and Strip" GB/T14978.

　　2.結(jié)構(gòu)性能冷彎薄壁型鋼鋼材強(qiáng)度設(shè)計(jì)值應(yīng)按下表采用。冷彎薄壁型鋼材強(qiáng)度設(shè)計(jì)值（N/mm?）鋼材牌號鋼材厚度t（mm）屈服強(qiáng)度fy抗拉、抗壓和抗彎f抗剪fv端面承壓（磨平頂緊）feQ235鋼t≤6.0235205120310Q345鋼t≤6.0345300175400Q550鋼t≤0.6585500285—0.6＜t≤0.95504702700.9＜t≤1.25154402501.2＜t≤1.54654002303.鍍鋅量要求最小鍍層要求是保護(hù)鋼材不被腐蝕，對鍍鋅層厚度的使用按設(shè)計(jì)的要求進(jìn)行。常用鍍鋅量要求如表下表所示。最小鍍鋅量要求（g/㎡）地區(qū)類別鍍鋅量最低要求一般地區(qū)180沿海地區(qū)、高腐蝕性地區(qū)275

　　2. The strength design values of cold-formed thin-walled steel for structural performance should be adopted according to the following table. Design value of strength for cold-formed thin-walled steel (N/mm?) Steel grade Steel thickness t (mm) Yield strength fy Tensile, compressive, and bending strength f Shear strength fv End face compression (ground flat and tightened) feQ235 steel t ≤ 6.0235205120310Q345 steel t ≤ 6.0345300175400Q550 steel t≤0.6585500285—0.6＜t≤0.95504702700.9＜t≤1.25154402501.2＜t≤1.54654002303. The minimum requirement for galvanized coating is to protect the steel from corrosion, and the thickness of the galvanized layer should be used according to the design requirements. The commonly used galvanizing requirements are shown in the table below. Minimum requirement for galvanizing amount (g/㎡) Regional category Minimum requirement for galvanizing amount General area 180 Coastal area, high corrosive area 275

　　4.鋼材的耐腐蝕性能根據(jù)建筑物建造地點(diǎn)環(huán)境不同，型鋼鍍鋅量要求也不同。鋅層多少決定房屋構(gòu)造使用壽命。目前，各國標(biāo)準(zhǔn)基本分三擋：1）構(gòu)件地處潮濕環(huán)境且裸露狀態(tài)時，鍍鋅量要求275克/m? (相當(dāng)鍍鋅厚度為20微米);2 ）承重及外墻構(gòu)件，鍍鋅量要求180克/m? (相當(dāng)鍍鋅厚度為13微米);3 ）非承重構(gòu)件, 鍍鋅量要求120克/m?(相當(dāng)鍍鋅厚度為8微米);

　　4. The corrosion resistance of steel varies depending on the environment of the building construction site, and the requirements for the amount of galvanizing on the steel section also differ. The amount of zinc layer determines the service life of the building structure. At present, the standards of various countries are basically divided into three levels: 1) When the component is located in a humid environment and exposed, the required amount of galvanizing is 275 grams/m ? (equivalent to a galvanizing thickness of 20 microns); 2) The load-bearing and exterior wall components require a galvanizing amount of 180 grams/m ? (equivalent to a galvanizing thickness of 13 microns); 3) Non load bearing components require a galvanizing amount of 120 grams/m ? (equivalent to a galvanizing thickness of 8 microns);

　　根據(jù)英國鋼鐵公司對不同地區(qū)、環(huán)境的15棟輕鋼住宅跟蹤取樣測試結(jié)果是：輕鋼鍍鋅構(gòu)件銹蝕率為三年平均不到0.1微米，也就是說，8微米厚鍍鋅冷彎薄壁型鋼構(gòu)件，正常使用條件下，使用壽命可達(dá)240年。而一般住宅設(shè)計(jì)壽命僅60年；

　　According to the tracking sampling test results of 15 light steel residential buildings in different regions and environments by British Steel Company, the corrosion rate of galvanized components of light steel is less than 0.1 microns on average over three years. In other words, the 8-micron thick galvanized cold-formed thin-walled steel components can have a service life of 240 years under normal use conditions. However, the design lifespan of general residential buildings is only 60 years;

　　美國國家住宅研究中心NAHB對4棟地處環(huán)境較差寒冷或炎熱近海地域輕鋼住宅跟蹤取樣測試結(jié)果表明：目前采用的輕鋼鍍鋅構(gòu)件住宅使用壽命可達(dá)100年以上；

　　The National Center for Housing Research (NAHB) in the United States conducted tracking sampling tests on four light steel residential buildings located in cold or hot coastal areas with poor environmental conditions. The results showed that the current use of light steel galvanized components in residential buildings can have a service life of over 100 years;
