The Study On Designe And Construction Technology For The Overhanging Arch Steel Scaffold With Door Style

With the rapid development of economic and the innovation of technology, construction industry is facing unprecedented opportunities and challenges. The key part of the enterprise competition is benefits. How to save costs and create benefits under the premise of safety first is the most significant task to the company. Overhanging arch steel scaffold with door style is not only security but also could create considerable profits. But at present, the study of it has just started in our country. The overhanging one is even fewer and mainly concentrated on the simple operations like the decoration.The first chapter of the paper concludes the problems existing in scaffolds and introduced the strengths in safety, economics and social benefits, giving application of overhanging one in the high-rise buildings at the same time. The importance and the purpose are proposed. Some literatures related to the scaffold are introduced in the second chapter. Urgent needs for research of scaffold are thrown by comparing with developed countries especially Japanese application and promotion. The third to fifth chapters are the key parts of the paper. Basic theory of overhanging arch steel scaffold with door style is introduced. First is the construction technology including preparation, arrangement of cantilever beam, base layout, vertical erection, horizontal erection, connecting tube installation and safety net layout. Operation requirement is also proposed in this part. The second part is the mechanics calculation. The last part is about the special construction program. It gives the illustration in the application of scaffold, including project summary, compilation foundations, construction organization, design and calculation of scaffold, quality requirement, site layout management, safety technical measures and the picture of scaffold arrangement, which used to specifically indicate the application of overhanging arch steel scaffold with door style. It also introduces mechanics calculation and material check, descripts the arrangement of manpower, material and finance for economic benefit, followed with the main points to achieve safe and civilized construction.This paper gives the answers to why to use the overhanging arch steel scaffold with door style, what is the basis of construction, how to organize the construction. All these answers constitute the foundation of scaffold application, giving a great significance to the application and promotion of it.
