牌楼也叫牌坊,最早见于周朝,最初用于旌表节孝的纪念物,后来在园林、寺观、宫苑、陵墓和街道均有建造,北京是中国牌楼最多的城市。牌楼是中国文化的独特景观,是由文化诞生的建筑,如文化迎宾门。又是中国特有的建筑艺术和文化载体。
牌坊在周朝的时候就已经存在了,《诗·陈风·衡门》:“衡门之下,可以栖迟。”《诗经》编成于春秋时代,大抵是周初至春秋中叶的作品,由此可以推断, “衡门”至迟在春秋中叶即已出现。衡门是什么呢?当时是以两根柱子架一根横梁的结构存在的,旧称“衡门”也就是我们现在所说的牌坊的老祖宗。
凯旋门是欧洲一种纪念战争胜利的建筑。始见于古罗马时期,当时统治者以此炫耀自己的功绩。后为欧洲其他国家所沿用。常建在城市主要街道中或广场上。用石块砌筑,形似门楼,有一个或三个拱券门洞,上刻宣扬统治者战绩的浮雕。
巴黎凯旋门,即雄狮凯旋门(法语:l’Arc de triomphe de l’Étoile),位于法国巴黎的戴高乐广场中央,香榭丽舍大街的西端。凯旋门正如其名,是一座迎接外出征战的军队凯旋的大门。它是现今世界上最大的一座圆拱门,位于巴黎市中心戴高乐广场中央的环岛上面。这座广场也是配合雄狮凯旋门而修建的,因为凯旋门建成后,给交通带来了不便,于是就在19世纪中叶,环绕凯旋门一周修建了一个圆形广场及12条道路,每条道路都有40~80米宽,呈放射状,就像明星发出的灿烂光芒,因此这个广场又叫明星广场。凯旋门也称为“星门”。凯旋门就位于著名的香榭丽舍大街的尽头。
方尖塔,是古埃及特有的一种建筑物,四方柱形,用整块花岗岩制成,通常是对地耸立在巨大的庙殿门前,作为崇拜太阳神的象征之一。现存埃及本土的方尖塔中总数已不超过10根,而且多为单根。可是,在罗马帝国时代到欧洲和美洲都市广场上的方尖塔却有50根之多。
作为一个万能的建筑体系,轻钢怎么能不在这类建筑中插一脚呢!
有没有想给母校捐个校门的想法?
我看行!
下面这个项目位于东南亚,谁能告诉我这个塔是什么作用?
轻钢方尖塔
以上案例,拿出任何一个项目,和其它建造方式进行造价比较,都有绝对优势。

Cold-formed steel is widely used in buildings, automobiles, equipment, home and office furniture, utility poles, storage racks, grain bins, highway products, drainage facilities, and bridges. Its popularity can be attributed to ease of mass production and prefabrication, uniform quality, lightweight designs, economy in transportation and handling, and quick and simple erection or installation.
冷弯型钢广泛应用于建筑、汽车、设备、家庭办公家具、电线杆、仓储货架、粮仓、公路产品、排水设施、桥梁等。它的普及可以归因于易于大规模生产和预制,统一的质量,轻量化的设计,运输和装卸的经济,快速和简单的组合或安装。
In building construction, cold-formed steel products can be classified into three categories: members, panels, and prefabricated assemblies. Typical cold-formed steel members such as studs, track, purlins, girts and angles are mainly used for carrying loads while panels and decks constitute useful surfaces such as floors, roofs and walls, in addition to resisting in-plane and out-of-plane surface loads. Prefabricated cold-formed steel assemblies include roof trusses, panelized walls or floors, and other prefabricated structural assemblies. Cold-formed steel possesses a significant market share because of its advantages over other construction materials and the industry-wide support provided by various organizations that promote cold-formed steel research and products, including codes and standards development that is spearheaded by the American Iron and Steel Institute (AISI).
在建筑施工中,冷弯型钢产品可以分为三类:构件、面板和预制组件。典型的冷弯型钢构件,如螺柱、轨道、檩条、梁和角钢主要用于承载荷载,而面板和甲板构成有用的表面,如地板、屋顶和墙壁,除了抵抗平面内和平面外的表面荷载。预制冷弯型钢组件包括屋顶桁架、镶板墙或地板,以及其他预制结构组件。由于冷弯型钢相对于其他建筑材料的优势,以及由促进冷弯型钢研究和产品的各种组织提供的全行业支持,包括由美国钢铁协会(AISI)牵头的规范和标准开发,冷弯型钢占有重要的市场份额。
Cold-formed steel applications can be traced back as early as the 1850s in both the United States and Great Britain. In the late 1920s and early 1930s, cold formed steel entered the building construction arena with products manufactured by a handful of fabricators. Although these products were successful in performance, they faced difficulties with acceptance for two reasons: (1) there was no standard design methodology available, and (2) cold-formed steel was not included in the building codes at that time. Many of the cold-formed steel applications were unable to be used due to the lack of design methodology and product recognition.
在美国和英国,冷弯型钢的应用可以追溯到19世纪50年代。在20世纪20年代末和30年代初,冷弯型钢进入了建筑建筑领域,其产品由少数制造商生产。尽管这些产品在性能上是成功的,但由于两个原因,它们面临着难以接受的困难:(1)没有可用的标准设计方法,(2)当时冷弯型钢没有包括在建筑规范中。由于缺乏设计方法和产品认可,许多冷弯型钢应用程序无法使用。
Cold-formed steel products are shaped at ambient temperatures from steel sheet, strip plate or flat bars by roll-forming machines, press brakes or bending brake operations. They can be produced in large quantity and at high speed with consistent quality. A typical automated rolling machine can run at a speed range of 75-400 feet per minute, and the products can be as small as a three-quarter inch wide cold-rolled channel section to as big as a thirty-six inch wide roof deck section.
冷弯型钢产品是在环境温度下由钢板、带材或扁钢通过滚压成型机、压闸机或弯闸机操作成型的。它们可以大批量、高速度、高质量地生产。一台典型的自动卷板机可以以每分钟75-400英尺的速度运行,产品可以小到3 / 4英寸宽的冷轧槽段,大到36英寸宽的屋顶甲板段。
