【摘要】：近年来,随着中国建筑业的迅猛发展,国内多个城市超高层犹如春笋拔地而起,随之也出现了多种比较新的模板系统,比如深圳京基和广州东塔项目的顶升模板系统、东莞国际金融中心项目的爬升模板系统等。模板工程虽然造价只占钢筋混凝土结构的四分之一,但劳动量与工期却远远大于这个数值。传统模板材料有木模板.、钢模板.、竹胶合模板,新型的模板材料有铝合金模板和塑料模板等。在对比了各种指标之后,铝合金模板以其质量轻、拆装方便、承载能力高,构件耐久性好、周转次数高,现场无施工垃圾,通用性强,回收价值高等优点脱颖而出,越来越多地运用于沿海地区超高层建筑中。本文以深圳下沙社区改造项目为依托,详细论证了项目铝合金模板体系设计方案、得出优化后的铝合金模板设计方案。优化设计方案是从各部位铝合金模板的设计到铝合金模板的安装、特殊部位的处理进行阐述,并通过有限元MIDASGen对铝合金模板设计方案进行模拟验算。在模拟过程中,重点考虑了铝合金模板节点连接方式、支撑体系设计方案等等,这为优化后的铝合金模板提供理论依据。采用类似年度等值法将铝合金模板与其他两种模板进行技术经济对比分析,计算得出三种模板周转均摊费,结果显示相同条件下使用铝合金模板更为经济。通过几种超高层常用模板体系关键施工方案及经济效益的对比分析,进行有限元模拟验算,得出铝合金模板体系较木塑模板、钢模板具有更多的优势。该研究具有在超高层建筑的施工中广泛的应用价值。
[Abstract]:In recent years, with the rapid development of China construction industry, a number of domestic city high-rise built like the bamboo shoots, but also the emergence of a variety of new template system, such as Shenzhen and Guangzhou East Tower Project of the Beijing based lifting formwork system, Dongguan international financial center project template climbing system.
Although the cost of formwork engineering only reinforced concrete structure 1/4, but the amount of labor and time is far greater than this value. The traditional template material with wood template., steel template, bamboo plywood form, new materials Aluminum Alloy template template and plastic template. After comparing the various indicators, Aluminum Alloy template with its light weight, easy disassembly, high bearing capacity, good durability, high turnover frequency, no construction waste, strong versatility, high recovery value talent shows itself, more and more widely used in high-rise buildings in the coastal area.
This paper takes Shenzhen Xiasha community transformation project, a detailed demonstration of the design Aluminum Alloy formwork system project, optimized the Aluminum Alloy template design. Optimization design is from various parts of Aluminum Alloy template design to Aluminum Alloy template installation, processing of special parts is expounded, and through the finite element simulation MIDASGen to check the design scheme of Aluminum Alloy template. In the simulation process, we focus on Aluminum Alloy template node connection, support system design and so on, which provides the theoretical basis for Aluminum Alloy template after optimization.
A similar annual equivalent economic and technical analysis will be compared with the other two Aluminum Alloy template template template, calculated three turnover capitation fee, the results showed that the use of Aluminum Alloy template under the same conditions is more economical.
Through the comparison of several commonly used super high formwork system key construction scheme and economic benefit analysis, finite element simulation, the Aluminum Alloy formwork system is wood formwork, steel formwork has more advantages. The research is in the construction of super high-rise building in the widely used value.
