中国目前高空施工中使用的基本上是钢管脚手架,它是中国解放前替代了传统竹子制作的移动脚手架的替代品,发展到今天已经经历了八十多年的历史.中国现在使用钢管材料制作的移动脚手架有扣件式钢管脚手架、碗扣式钢管脚手架、承插式钢管移动脚手架、门式脚手架,还有各式各样的里移动脚手架、挂挑门式脚手架以及其它钢管材料门式脚手架。从其材料和构造情况来着手,并可将其大致划分如下:
At present, steel pipe scaffolding is basically used in high-altitude construction in China. It is a substitute for traditional bamboo mobile scaffolding before liberation. It has been developed for more than eighty years. The mobile scaffolding made of steel pipe materials in China now includes fastener-type steel pipe scaffolding and bowl-buckle steel pipe scaffolding. Scaffolding, socket steel pipe scaffolding, portal scaffolding, as well as a variety of inside scaffolding, hanging scaffolding and other steel pipe material scaffolding. Starting from its material and structure, it can be roughly divided into the following: 按杆件的材料划分
Material division according to bar member
1)单一规格钢管的梯形脚手架。它只使用一种规格的钢管,如扣件式钢管梯形脚手架,只使用Ф48×3.5的电焊钢管。
1) single standard steel pipe scaffold. It only uses one kind of steel pipe, such as fastener type steel pipe scaffold, and only uses 48 x 3.5 welded steel pipe.
2)多种规格钢管组合的脚手架。它由两种以上的不同规格的钢管构成,如门式脚手架。
2) scaffolds with various specifications of steel pipes. It consists of two or more kinds of steel pipes, such as portal scaffolds.
3)以钢管为主的脚手架。即以钢管为主,并辅以其它型钢杆件所构成的脚手架,如设有槽钢顶托或底座的里脚手架,有连接钢板的挑脚手架等。架子管,建筑管材,通常用来制作建筑工地上的支架,是由热轧带钢经过工艺处理后,卷成的产品。在现代的建筑工地上,架子管已被普遍使用,随处都可以看到它的身影。 近几年,随着城市化建设的迅速发展,架子管的需求量也就越来越大。同时国家也出台了一些措施来鼓励架子管行业的发展。其中,重点强调了建筑工程专业的架子管的发展。而用于建房建筑的架子管,则所需品种多样,可供选择的范围也比较广。 因此,架子管厂家更是加快了重组步伐,以确立架子管企业在市场的主导地位。
3) steel pipe scaffold. That is to say, scaffolding consisting mainly of steel pipes and supplemented by other steel members, such as inner scaffolding with channel steel top bracket or base, and lifting scaffolding with connecting steel plates, etc. Shelf pipes, building pipes, are usually used to make support on construction sites. They are coiled products of hot rolled strip steel after processing. On modern construction sites, rack tubes have been widely used and can be seen everywhere. In recent years, with the rapid development of urbanization, the demand for rack tubes is increasing. At the same time, the government has also introduced some measures to encourage the development of the shelf management industry. Among them, the emphasis is placed on the development of shelf management of building engineering. The shelf pipes used for building buildings need variety and wide range of choices. Therefore, the shelf tube manufacturers are accelerating the pace of restructuring to establish the dominant position of shelf tube enterprises in the market.
架子管行业的发展趋势会随着市场的变化而发展。企业的经营和管理已经从过去的单一目标式发展开始向科学化、统化的管理进行转变。而商品混凝土泵送现浇钢筋混凝土结构体系的形成,更是促进了空间高、跨度大的模板支架的应用,在工程的施工中编制模板支架和高层脚手架的组织设计的已变得越来越明显。又因其具有结构简单合理、设计巧妙、使用方便、安全、快捷、易于运输、储存、维护简单等特性。因此在当时架子管的发展史上实现了三个第一:
The development trend of the rack and tube industry will develop along with the market changes. The operation and management of enterprises have changed from the single objective development in the past to the scientific and unified management. The formation of commercial concrete pumping cast-in-place reinforced concrete structure system promotes the application of formwork bracket with high space and large span. The organization design of formwork bracket and high-rise scaffold has become more and more obvious in engineering construction. Because of its simple and reasonable structure, ingenious design, easy to use, safe, fast, easy to transport, storage, simple maintenance and other characteristics. Therefore, in the development history of shelf management at that time, there were three first points:
第一个”实现了在架子管上无任何活动零件;
The first one realizes that there are no movable parts on the rack tube.
第一个”实现了我国对整体新型架子管的自主知识产权
The first is to realize our own intellectual property rights to the new type of rack pipe.
第一个”实现了架子管在结构上无任何专门的锁紧零件等。至今为止该产品已深受国内外用户的欢迎,被国内的路桥、市政、房建等单位所青睐。 脚手架碗方管协会这样的报道扣式钢管脚手架当采用钢管横杆时,为“单一钢管的脚手架”;当采用型钢搭边横杆时,为“以钢管为主的脚手架”。
The first one realizes that there are no special locking parts in the structure of the rack tube. Up to now, this product has been welcomed by domestic and foreign users, and is favored by domestic road and bridge, municipal, housing and other units. Scaffolding Bowl Square Pipe Association reports that buckled steel pipe scaffolding is "single steel pipe scaffolding" when steel pipe crossbar is used, and "steel pipe-based scaffolding" when steel profile is used to build side crossbar.
目前世界上一些发达国家以及我国的港澳地区对建筑施工的安全越来越重视,并且由于传统钢管脚手架太笨重,工人安装效率底,造成建筑成本大幅度上涨。这些地区已经开始逐步使用铝合金脚手架替代传统的钢管脚手架,铝合金脚手架的自身设计科学,搭建和拆卸快速,轻质,稳固,安全性比传统钢管脚手架有了很大的提升。所以脚手架行业将有我国解放前由竹子被钢管脚手架替代,到目前的钢管脚手架被铝合金脚手架替代,是未来发展的历史趋势。
At present, some developed countries in the world and Hong Kong and Macao regions in China pay more and more attention to the safety of construction. Because the traditional steel pipe scaffolding is too bulky and the installation efficiency of workers is low, the construction cost has risen substantially. Aluminum alloy scaffolding has been gradually used to replace the traditional steel tube scaffolding in these areas. Its own design is scientific. Its construction and disassembly are fast, light, stable, and its safety has been greatly improved compared with the traditional steel tube scaffolding. Therefore, the scaffolding industry will be replaced by bamboo scaffolding by steel tube scaffolding before liberation, and by aluminium alloy scaffolding by steel tube scaffolding at present, which is the historical trend of future development.
