【摘要】：随着经济的持续发展,超高层建筑日益显现出它的社会及经济效益,众多开发商在分享建筑行业发展所带来的巨大利益的同时,不断建设更高的建筑。在建设更高建筑的过程中,开发商要求缩短工期、尽早进行销售,以加快资金周转,保证资金回笼速度;施工单位则必须具备加快施工进度、提高施工质量的能力,才能满足这一需要,进而提高市场竞争力。对超高层而言,爬模技术的出现及应用,为极大缩小工程建设周期提供可能,从目前行业的技术水平看,针对超高层建筑的爬模技术的研究及探讨非常必要且及时。爬升模板施工是机械化程度较高的施工方法,在高层及超高层建筑中出现了极大的发展势头。整体爬模模板最大的特点是爬升速度快、操作方便、结构简单、整体稳定性高、高空作业的安全系数高,工程安全与质量得到保证。一般情况下,爬模架一次组装后,一直到顶不落地,既节省了施工场地,又能减少了模板的碰伤损毁,提高模板面板周转次数。但国内涉及爬模的核心技术并不全面,尤其是相关节点设计考虑不细致,涉及爬模节点设计因素考虑不全面,相关爬模方面的风险管理不到位,并且普遍存在竖向疏散通道与爬模的快速施工存在不匹配的现象。本文主要采用了实际案例分析及证明的研究方法,提出了超高层建筑施工中爬模体系在设计过程中的选型原则,通过对不同爬模系统的优缺点对比分析,结合深圳平安大厦的结构特点,确定采用爬升模板系统,并以深圳平安大厦建设为例,进行了相关方面的核心筒爬模节点设计,以工程实际操作为基础,归纳出超高层爬模在施工过程中遇到难点时的解决方案,为类似超高层建筑爬模的系统设计与过程施工提供可靠案例。论文还对爬模在实际操作过程中遇到的相关风险关键因素进行了分析,并提出了具体的解决方案;结合超高层建筑结构特点及爬模设计情况,研究和讨论了爬模体系垂直运输系统的设计问题。提出在爬模实施过程中,技术条件一定时,管理必须放在最重要的位置。
[Abstract]:With the sustainable development of economy, super-high-rise buildings increasingly show its social and economic benefits, many developers share the huge benefits brought by the development of the construction industry at the same time. In the process of building higher buildings, developers demand to shorten the construction period and sell as early as possible in order to speed up the turnover of funds and ensure the speed of the return of funds; The construction unit must have the ability to speed up the construction progress and improve the construction quality in order to meet this need, and then improve the market competitiveness. For the super high level, the appearance and application of climbing formwork technology. In order to greatly reduce the construction cycle of the project to provide the possibility, from the current technical level of the industry. It is necessary and timely to study and discuss the climbing formwork technology of super high-rise building. Climbing formwork construction is a construction method with high degree of mechanization. There is a great development momentum in high-rise and super-tall buildings. The biggest characteristics of integral climbing formwork are fast climbing speed, easy operation, simple structure, high overall stability and high safety factor of aerial work. The safety and quality of the project are guaranteed. In general, after once assembling the climbing mould frame, it can not only save the construction site, but also reduce the damage of the formwork. However, the core technology involved in climbing die is not comprehensive, especially the design of related nodes is not detailed, and the design factors of climbing die joints are not comprehensive. The risk management of the related climbing formwork is not in place and the phenomenon of mismatch between the vertical evacuation passage and the rapid construction of the climbing formwork is common. This paper mainly adopts the research method of actual case analysis and proof. This paper puts forward the selection principles of climbing formwork system in the design process of super high-rise building construction. Through the comparative analysis of the advantages and disadvantages of different climbing formwork systems and combining with the structural characteristics of Shenzhen Ping an Mansion, the climbing formwork system is adopted. Taking the construction of Shenzhen Ping an Mansion as an example, the paper designs the core tube climbing formwork node in related aspects. Based on the practical operation of the project, the solutions to the difficulties encountered in the construction process of the super high-rise climbing formwork are summarized. This paper provides a reliable case for the system design and process construction of the climbing formwork similar to the super high-rise building. The paper also analyzes the key risk factors encountered in the actual operation of climbing formwork and puts forward concrete solutions. According to the structural characteristics of super high-rise building and the design of climbing die, the design problem of vertical transportation system of climbing die system is studied and discussed. It is proposed that when the technical conditions are fixed in the process of implementing climbing die, the design problem of vertical transportation system of climbing die system is studied and discussed. Management must be at the top of the list.
