冷弯型钢做SPA池的案例
关于SPA一词起源的探讨中有一个词始终贯穿其中,那就是“水疗”,它反映了水在古时的治疗领域和早期欧洲SPA文化中的重要作用。多数人认为SPA一词是一些拉丁短语的首字母组合,如“sanitas per aquam”,“solus per aquam ”,“sanus per aquam”。这些短语都有“用水治疗”的意思。另一种说法是SPA源于在罗马浴室中发现的涂鸦“salut per aquam”。
SPA也可能源于瓦龙语的“espa”,意思是喷泉,或源于拉丁语“spagere”,意思是泼水。有些专家认为该词源于比利时一个以温泉著称的叫spa的小镇。后来,spa一词就被用于温泉和提供水疗的疗养胜地。在19、20世纪,饮用矿泉水或在矿泉中洗浴成为时尚的休闲方式。
在欧洲的许多地区,spa一词仍保持着其强烈的历史联系,并严格地被用于与水疗有关的机构。在欧洲的英语地区和世界上一些其他地区,spa一词的意义变得更加广泛,包括身心的健康和放松。
水是spa疗法中的关键因素,除此之外,还因侧重自然健康疗法、运动、健身、饮食营养和保持身心的协调。
早在公元前1500年,印度人就以这种“神水”疗伤镇痛,古希腊人也将其作为一剂治病强身的灵丹妙药,而在奢华的古罗马,人们更是利用水温的天然不同,将公共浴室分为很热、微热、冷池。这里成为勇士们洗净身体污垢的公共交流场所。
增补案例 天台增加小型SPA池
在上面的案例中,SPA池可以买到成品,或者叫按摩浴缸。一般采用亚克力材质。
亚克力游泳池的正式名称是玻璃纤维增强塑料泳池(亚克力是英语ACRYLIC的谐音)。其表层材料是甲基丙甲酯,反面覆上玻璃纤维,涂上专用树脂增强。整个泳池应色泽均匀,表面光滑,无分层、气泡等。表层厚度一般在3毫米以上,且和玻璃纤维结合牢固,无剥离。
亚克力泳池传热慢,因此保温性好,接触体表无“冰冷”感觉。与铸铁或钢板泳池相比,更有一种“温暖、柔软”感,不会碰痛躯体。由于亚克力的再加工性能较好,所以制造豪华的按摩泳池非它莫属。
亚克力泳池在安装时底部应满铺黄沙水泥糊,不能腾空或仅靠几个支撑点,以免断裂。使用中应防止尖硬物体磕碰摩擦,清洁时应用软布和清洁剂轻揩,忌用百洁布。一旦发现有擦毛,用软布加上牙膏擦拭,可恢复光泽。
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。
