建筑腳手架的安全問題一直是建筑施工中的難題,每年都會發生幾起腳手架倒塌安全事故。如何提高腳手架的安全度,確保移動腳手架的施工安全,下面借鑒日本移動腳手架的管理經驗談幾點看法:目前全國門式腳手架鋼管約有1000萬噸以上,其中劣質的、超期使用的和不合格的鋼管占90%以上,扣件總量約有10—12億個,合格品率為零.如此量大面廣的不合格鋼管和扣件,已成為建筑施工安全的隱患,要在短期內完成整治工作是不可能的。近年來,由于建筑和租賃市場混亂,生產和銷售劣質鋼管、扣件的違法行為突出,大量不合格的鋼管、扣件流入施工現場,加上施工單位不規范使用,嚴重危及建筑施工安全。最近,建設部,國家質檢總局、國家工商總局聯合發布了“關于開展建筑施工用鋼管、扣件專項整治的通知”,要求通過此次專項整治,使生產、銷售、租賃和使用的劣質建筑施工用鋼管、扣件的狀況得到明顯扭轉.

The safety of scaffolding has always been a difficult problem in construction. Several safety accidents of scaffolding collapse occur every year. How to improve the safety of scaffolding and ensure the construction safety of scaffolding? Here are some opinions based on the management experience of Japanese scaffolding. At present, there are more than 10 million tons of scaffolding steel pipes in China, of which 90% are inferior, overdue and unqualified. The total number of fasteners is about 1.0-1.2 billion, and the qualified rate is zero. Components have become hidden dangers of construction safety. It is impossible to complete the renovation work in a short time. In recent years, due to the chaotic construction and leasing market, the illegal activities of producing and selling inferior steel pipes and fasteners have become prominent. A large number of unqualified steel pipes and fasteners have flowed into the construction site, together with the irregular use of construction units, which seriously endangers the safety of construction. Recently, the Ministry of Construction, the State Administration of Quality Supervision and Inspection, and the State Administration of Industry and Commerce jointly issued the Notice on the Special Regulation of Steel Pipes and Fasteners for Construction, requesting that the situation of inferior construction steel pipes and fasteners for production, sale, leasing and use be significantly reversed through this special regulation. 一、大力開發新型門式腳手架是解決施工安全的重要保證

1. Vigorously developing new scaffolding is an important guarantee for solving construction safety

日本在50年代已開始大量應用扣件式鋼管梯形腳手架,到50年代中期,扣件式鋼管梯形腳手架的應用量已占主導地位,由于不斷發生傷亡事故,據介紹曾在一年內傷亡人數達到2856人,因此,腳手架的安全問題引起政府有關部門的高度重視.

In Japan, fastener-type steel tube scaffolding has been widely used in the 1950s. By the mid-1950s, the application of fastener-type steel tube scaffolding has dominated. As casualties continue to occur, it is reported that the number of casualties in one year has reached 2856. Therefore, the safety of scaffolding has attracted great attention from relevant government departments.

60年代初,由于門式腳手架裝拆方便、承載性能好、安全可靠,尤其是勞動省對腳手架的安全使用作出了規定,門式腳手架在工程中開始大量應用。70年代初,隨著日本超高層建筑日益增多,腳手架租賃業務的廣泛開展,門式腳手架的應用量迅速增長,并已成為主導腳手架.

In the early 1960s, because the portal scaffolding was easy to assemble and disassemble, good load-bearing performance, safe and reliable, especially the Ministry of Labor made provisions for the safe use of scaffolding, portal scaffolding began to be widely used in engineering. In the early 1970s, with the increasing number of super high-rise buildings in Japan and the widespread development of scaffolding leasing business, the application of portal scaffolding increased rapidly and has become the leading scaffolding.

目前,日本還開發和研究了H型、折疊式、碗扣式、圓盤式,插孔式、插槽式等多種類型腳手架。由于扣件式鋼管腳手架的安全性較差,在施工工程中已很少使用了。

At present, Japan has also developed and studied H-type, folding type, bowl-button type, disc type, Jack type, slot type and other types of scaffolding. Because of the poor safety of fastener-type steel pipe scaffolding, it has been rarely used in construction projects.

我國在60年代初開始應用扣件式鋼管腳手架,由于這種腳手架具有裝拆靈活、搬運方便、通用性強、價格便宜等特點,所以在我國應用十分廣泛,其使用量占60%以上,是當前使用量最多的一種腳手架。但是,這種腳手架的最大弱點是安全性較差,施工工效低。隨著我國大量現代化大型建筑體系的出現,這種腳手架已不能適應建筑施工發展的需要,因此,大力開發和推廣應用新型腳手架是當務之急。實踐證明,采用新型腳手架不僅施工安全可靠、裝拆速度快、而且腳手架用鋼量可減少33%左右,裝拆工效提高8-10倍以上,施工成本可明顯下降,施工現場文明、整潔。80年代初,我國先后從國外引進門式腳手架,碗扣式腳手架等多種型式腳手架.門式腳手架在國內許多工程中也曾大量應用過,取得較好的效果,但是,門式腳手架沒有得到大量推廣應用,不少門式腳手架生產廠紛紛關閉或轉產。現在國內還有少量門式腳手架生產廠,其產品大部分都是按外商來圖加工,出口國外。碗扣式腳手架是新型腳手架中,推廣應用最多的一種腳手架,但是使用面還不廣.只有國內部分地區和部分工程中大量應用,可是最近幾年我們國內市場上的碗扣式腳手架大都是河北一帶生產的非標產品,施工事故也接而連三,深是讓人擔憂。現在我國內市場上有一種最新開發的直插式雙自鎖型多功能鋼管腳手架就非常先進,能適應各種多樣化腳手架的拼裝和支護體系的應用。因此,大力開發和推廣應用新型直插式雙自鎖腳手架,逐步替代安全度較差的扣件式、門式、碗扣式腳手架,是解決腳手架施工安全的重要保證.

In the early 1960s, fastener-type steel tubular scaffolding was applied in China. Because of its flexible assembly and disassembly, convenient handling, strong versatility and low price, it is widely used in China. Its usage accounts for more than 60%, and it is the most widely used scaffolding at present. However, the biggest weakness of this scaffold is its poor safety and low construction efficiency. With the emergence of a large number of modern large-scale building systems in China, such scaffolding can not meet the needs of construction development. Therefore, it is urgent to vigorously develop and promote the application of new scaffolding. Practice has proved that the new scaffolding is not only safe and reliable in construction, fast in installation and disassembly, but also can reduce the amount of steel used in scaffolding by about 33%, increase the efficiency of installation and disassembly by more than 8-10 times, reduce the construction cost significantly, and make the construction site civilized and clean. In the early 1980s, China introduced many types of scaffolds, such as portal scaffolding, bowl-buckled scaffolding and so on. Portal scaffolding has been widely used in many domestic projects and achieved good results. However, portal scaffolding has not been widely promoted and applied, and many production plants of portal scaffolding have closed or changed their production. At present, there are a small number of domestic gantry scaffolding manufacturers, most of their products are processed according to foreign maps and exported to foreign countries. Bowl-buckle scaffolding is a new type of scaffolding, which is the most widely used scaffolding, but it is not widely used. It is only widely used in some areas and some projects in China. However, in recent years, most of the bowl-buckle scaffolding in our domestic market are non-standard products produced in Hebei area, and construction accidents are successive, which is deeply worrying. Now there is a newly developed straight insertion double self-locking multi-functional steel tube scaffolding on the domestic market, which is very advanced and can adapt to the application of various kinds of scaffolding assembly and support system. Therefore, vigorously developing and popularizing the application of new straight inserting double self-locking scaffolding, gradually replacing the less safe fastener-type, door-type and bowl-type scaffolding, is an important guarantee to solve the construction safety of scaffolding.
