【摘要】：近些年,随着经济迅猛发展,建筑业蓬勃发展欣欣向荣,国内外超高层建筑层出不穷,随之也出现了很多种比较新型的脚手架系统。比如长沙运达中央广场DS型附着式整体升降脚手架系统,佛山保利商贸中心智能导轨式爬架体系等等。脚手架工程虽然只是建筑物外的临时结构,但是它在建筑物施工过程起着至关重要的作用。尤其对工程进度工期的影响和经济效益的控制等方面。传统脚手架材料有木、竹、钢管等,新型的脚手架材料有铝合金板和钢板等。在对比各项指标之后,附着式升降脚手架以其安装拆卸方便、维护保养简便、防火耐用、架体外形美观、显著节约成本、爬架平台作业环境更具人性化、避免高空散装散拆的坠物隐患等优点优势脱颖而出,越来越广泛的运用于国内外地区超高层建筑中。本文以深圳君临海域名园二期工程项目为依托,详细阐述了项目附着式升降脚手架体系设计方案、得出优化后附着式升降脚手架的设计方案。优化设计方案是从各部位附着式升降脚手架的设计到附着式升降脚手架的安装、特殊关键部位的处理进行阐述,并通过设计规范对附着式升降脚手架方案进行计算验算校核。在验算过程中,重点考虑了附着式升降脚手架节点连接方式、支撑体系受力分析、各个构件挠度承载力验算等等,这为优化后的附着式升降脚手架提供可靠的理论依据。采用总价对比分析法将附着式升降脚手架与悬挑脚手架进行经济对比分析,结果显示相同条件下使用附着式升降脚手架体系更为经济。除此之外又考虑工期因素,根据项目进度奖惩机制产生不同经济效益,综上所述,附着式升降脚手架更为经济适用。通过几种超高层常用脚手架体系施工技术方案及经济的对比分析,进行计算验算校核,得出附着式升降脚手架体系较悬挑脚手架以及传统脚手架具有更多的优势。该研究成果在超高层建筑的施工中具有广泛的应用价值。
[Abstract]:In recent years, with the rapid development of the economy, the construction industry is booming, and the super-tall buildings at home and abroad are emerging in endlessly. There are also many new scaffolding systems, such as Changsha Yunda Central Plaza DS attached integral lifting scaffolding system, Foshan Poly Trade Center intelligent rail climbing system and so on. Scaffolding works are only temporary structures outside buildings, but they play an important role in the construction process of buildings, especially in the control of construction schedule and economic benefits. Traditional scaffolding materials include wood, bamboo, bamboo, etc. Steel tubes, new scaffolding materials such as aluminum alloy plate and steel plate. After comparing the various indicators, the attached lifting scaffolding is easy to install and disassemble, easy to maintain, fire-resistant and durable, and its shape is beautiful, and the cost is significantly reduced. The working environment of the climbing platform is more humanized, and the advantages of avoiding the hidden danger of falling objects in bulk are more and more widely used in the super high-rise buildings at home and abroad. Based on the second phase project of Shenzhen Junlinhai Domain Park, this paper expounds the design scheme of the attached lifting scaffold system in detail. The optimum design scheme is from the design of the attached lifting scaffold to the installation of the attached lifting scaffold, and the treatment of the special key parts is described. In the process of checking calculation, the joint connection mode of attached lifting scaffold, the force analysis of support system, the deflection bearing capacity of each member and so on are considered. This provides a reliable theoretical basis for the optimized attached lifting scaffold. The economic comparison analysis between attached lifting scaffold and cantilever scaffold is carried out by means of total price contrast analysis. The results show that it is more economical to use attached lifting scaffold system under the same conditions. According to the project schedule reward and punishment mechanism produces different economic benefits, in summary, the attached lifting scaffold is more economical and applicable. Through the comparison and analysis of construction technology and economy of several kinds of scaffolding systems commonly used in super high buildings, the calculation, checking and checking are carried out. It is concluded that the attached lifting scaffold system has more advantages than the cantilever scaffold and the traditional scaffold. The research results have wide application value in the construction of super high-rise building.
