二、轻钢建筑基本情况说明
澳大利亚早在20世纪60年代就提出了“快速安装预制住宅”的概念，但由于市场尚未成熟，并未得到很好发展。到了1987年，高强度冷弯薄壁钢结构出现，澳大利亚与新西兰的联合规范AS/NZS4600冷弯成型结构钢规范于1996年发布实施。这种钢材承载力高，与相同承载力的木材相比，只是木材的1/3重，表面经镀锌处理，在免大修的情况下，耐久性可达75年。
在中国建房市场近年刮出了一阵“轻钢别墅风”，这一新鲜事物引起了很多人得关注，但是由于轻钢别墅房屋的信息缺失，大多数人都在观望当中，其实轻钢房在90年代已经出现在中国，只是因为当时技术问题受制于国外发达国家，直至今日，钢结构房屋的技术成熟，由国家推动，正式进入大众的视野。那么国外发达国家都是怎样建房的呢？由于环保意识的加强和木材短缺等因素，许多国家如美国、日本、英国、澳大利亚等，正积极地推动中低层轻钢别墅的应用与发展。
轻钢别墅在美国发展最快，1965年轻钢别墅在美国仅占建筑市场15%;1990年就上升到53%，而1993年则已上升到68%，到2000年已经上升到75%。住宅用构件和部晶的标准化、系列化，及其专业化、商品化、社会化程度很高，几乎达到100%，各种施工机械、设备、仪器等租赁化非常发达，商品化程度达到40%。
近年来，全部构件均采用冷成型钢的轻钢龙骨体系建筑作为一种新兴的建筑方法正在欧美迅速发展，日益成为一种可订购的特殊商品，广泛应用于别墅、住宅、景区配套、办公会所、学校、医院、商业建筑等。在澳大利亚，每年约建造6亿美元的轻钢龙骨独立式住宅120000栋，约占澳大利亚所有建筑业务产值的24%;在美国，采用该体系建造的房屋从20世纪90年代中期的55000栋剧增为2000年的325000栋。目前这种轻钢别墅己成为发达国家的主要建筑结构形式。
包括单层和多层的住宅和公寓在内的轻钢别墅体系之所以如此迅猛发展、方兴未艾，有其深刻的原因:与其他形式钢结构住宅相比较，朗驰轻钢集成房屋体系尤其是冷弯薄壁型轻钢龙骨住宅具有一些独特的综合优势:
(1)轻钢别墅轻质高强，抗震性能好，安全性高。建筑自重轻，仅相当于混凝土结构的一半左右。
(2)轻钢龙骨体系构配件制作工厂化和机械化、商品化程度高，易于实现产业化、工业化，可以缩短施工周期。
(3)构件截面小，与混凝土结构相比可增加建筑有效面积8%左右。屋面采用钢桁架结构，可建造出丰富多姿的屋顶形式，外形美观，满足建筑个性化要求。
(4)室内水电气管线可全部暗埋在墙体中，布置灵活、修改方便。适于采用科技含量高的环保节能墙板、楼板及屋面板，节能效果好。
(5)轻钢别墅施工噪音小，建筑垃圾少，所用材料主要是可以回收或易降解的材料，有利于生态环境保护，符合绿色建筑和可持续发展的要求，属于绿色环保型建筑。
(6)轻钢别墅节能环保，相较于普通砖混结构，轻钢结构总能耗节约30%，二氧化碳排放量减少67%。
根据实践应用的结果，在地震区、软土地基建造住宅，采用轻钢别墅体系可比钢筋混凝土结构体系造价略低或持平，具有较强的竞争力。
考虑到长远的使用、发展趋势和环保要求，轻钢别墅发展前景好，市场需求量大，将逐渐成为房屋市场新的“卖点”。虽然现在轻钢别墅在国内还未得到大规模推广应用，但是我们相信在不久的将来，轻钢别墅就能在中国这片热土上遍地开花。

Brief Introduction of Sihe Construction Engineering Development Company and Basic Information of Light Steel Construction
1. Company profile
Sihe Construction Development Co., Ltd. is a comprehensive national development company incorporated in Nepal that integrates traditional buildings and modern light steel buildings.
The company adheres to the business and service philosophy of "international vision, customer first, quality first, and comprehensive development", with Nepal as the center, tracing the South Asian market, taking light steel construction as a breakthrough, and comprehensively expanding the light steel construction market to provide services to South Asian countries Light steel construction services with market development potential allow you to realize your dream of low-cost ultra-luxury villas.
The seven South Asian countries are Nepal, India, Pakistan, Sri Lanka, Bangladesh, Bhutan, and Maldives, with a total population of more than 1.5 billion people, which is a market with huge potential for development.
After the establishment of Sihe Construction Company, according to the decision of the Chinese head office, it plans to start the promotion and sales of light steel construction in seven countries in South Asia with Nepal as the center, and establish a complete and efficient marketing management team, which will be comprehensive after the epidemic. Promote.
2. Description of the basic situation of light steel construction
Australia put forward the concept of "quick installation of prefabricated houses" as early as the 1960s, but because the market is not yet mature, it has not been well developed. In 1987, high-strength cold-formed thin-walled steel structures appeared, and the Australian and New Zealand joint specification AS/NZS4600 for cold-formed structural steel was issued and implemented in 1996. This kind of steel has a high bearing capacity. Compared with wood of the same bearing capacity, it is only 1/3 heavier than the wood. The surface is galvanized, and the durability can reach 75 years without major repairs.
There has been a “light steel villa wind” in the Chinese housing market in recent years. This new thing has attracted a lot of attention. However, due to the lack of information about light steel villa houses, most people are waiting and watching. In fact, light steel houses It has appeared in China in the 1990s, only because the technical problems at that time were constrained by foreign developed countries. Until today, the technology of steel structure houses is mature, promoted by the state, and formally entered the public's field of vision. So how do foreign developed countries build houses? Due to factors such as the strengthening of environmental awareness and the shortage of wood, many countries such as the United States, Japan, the United Kingdom, Australia, etc. are actively promoting the application and development of low- and medium-rise light steel villas.
Light steel villas have developed the fastest in the United States. In 1965, young steel villas accounted for only 15% of the construction market in the United States; it rose to 53% in 1990, 68% in 1993, and 75% in 2000. The standardization and serialization of residential components and parts, and their specialization, commercialization, and socialization are very high, reaching almost 100%. The leasing of various construction machinery, equipment, instruments, etc. is very developed, with a commercialization degree of 40 %.
In recent years, light-steel keel system buildings made of cold-formed steel for all components are rapidly developing in Europe and America as a new construction method. It has increasingly become a special orderable commodity, which is widely used in villas, residences, scenic spots, and office clubs , Schools, hospitals, commercial buildings, etc. In Australia, 120,000 light-steel keel detached houses worth about $600 million are built each year, accounting for about 24% of the output value of all construction businesses in Australia; in the United States, the number of houses built using this system has increased sharply from 55,000 in the mid-1990s. There were 325,000 buildings in 2000. At present, this kind of light steel villa has become the main architectural structure in developed countries.
The light steel villa system, including single-story and multi-storey houses and apartments, is developing so rapidly and in the ascendant. There are profound reasons: Compared with other forms of steel-structured houses, the Langchi light steel integrated house system is particularly cold. The curved thin-walled light steel keel residence has some unique comprehensive advantages:
(1) Lightweight steel villas are lightweight and high-strength, with good seismic performance and high safety. The weight of the building is light, only about half of the concrete structure.
(2) The production of light steel keel system components is factoryized, mechanized, and commercialized, which is easy to realize industrialization and industrialization, and can shorten the construction period.
(3) The component section is small, which can increase the effective area of the building by about 8% compared with the concrete structure. The roof adopts a steel truss structure, which can build a rich and colorful roof form with a beautiful appearance and meet the individual requirements of the building.
(4) The indoor water and electricity pipelines can all be buried in the wall, with flexible layout and convenient modification. It is suitable for the use of environmentally-friendly and energy-saving wall panels, floor panels and roof panels with high technological content, with good energy saving effects.
(5) Light steel villas have low construction noise and low construction waste. The materials used are mainly recyclable or easily degradable materials, which are conducive to ecological environment protection, meet the requirements of green buildings and sustainable development, and belong to green buildings.
(6) Light steel villas are energy-saving and environmentally friendly. Compared with ordinary brick-concrete structures, light steel structures can save 30% in total energy consumption and reduce carbon dioxide emissions by 67%.
According to the results of practical application, in the earthquake zone and soft soil foundation, the light steel villa system can be slightly lower or the same as the construction cost of the reinforced concrete structure system, and it has strong competitiveness.
Taking into account the long-term use, development trend and environmental protection requirements, light steel villas have good development prospects and large market demand, which will gradually become a new "selling point" in the housing market. Although light steel villas have not yet been widely promoted and applied in China, we believe that in the near future, light steel villas will bloom everywhere in this hot land of China.
