【摘要】：在我国，建筑结构形式正朝着大型化和复杂化方向持续发展，超限、超重、高净空、大跨度模板支撑系统不断涌现，特别是在商业综合体、公共建筑、高层建筑施工中，高大支模体系已十分普遍，由于扣件式钢管支模架取材容易(钢管、扣件同普通外架)、搭设方便、成本较低,因此扣件式钢管支模架应用十分普遍。 现阶段国内高支模架项目事故频发，，已成为工程建设项目整体中高风险重要因素之一，其重要性及特殊性日益的到关注，必须通过单独、严谨、科学和可靠的分析，才能得到最终满意的效果。 本文根据嘉兴经投商务大厦工程中高支模架的实际情况，本文对高支模架进行了实用简化计算。在计算过程中，针对高支模架各重要因素进行分析，其中包括整体强度、变形、整体与局部失稳等。在此基础上，变化部分模架布置进行了计算分析比较，以期获得更合理的模架布置与更好的经济效果，计算结果表明，原计算结果仍有可以优化的余地。最后，本文对高支模架施工质量保证体系进行了分析，通过实际工程顺利实施，说明良好的施工保障措施是使设计的模架得以顺利实施的重要因素。 本文论述的高支模架计算与方案比较及相应施工质量保证体系使高支模架本工程中顺利实施，对其它相似工程有一定的借鉴作用。
[Abstract]:In our country, the form of building structure is developing continuously towards the direction of large scale and complication, which is over limit, overweight, high clearance and large span formwork support system, especially in the construction of commercial complex, public building and high-rise building. It is very common to use fastener steel tube support die frame because of its easy material (steel tube, fastener and common outer frame), convenient installation and low cost. Therefore, the application of fastener type steel tube support die frame is very common. At the present stage, the frequent accidents of high support mould frame project in China have become one of the important factors of high risk in the whole project of engineering construction. Its importance and particularity are paid more and more attention to, which must be analyzed separately, rigorously, scientifically and reliably. In order to get the final satisfactory results. According to the actual situation of high support mould frame in Jiaxing Jingtuan Commercial Building, this paper makes a practical and simplified calculation of high support die frame. In the course of calculation, various important factors of high support die frame are analyzed, including overall strength, deformation, whole and local instability, etc. On this basis, the calculation and comparison of the changing part of the die frame arrangement are carried out in order to obtain more reasonable die frame arrangement and better economic effect. The calculation results show that the original calculation results still have room for optimization. Finally, this paper analyzes the construction quality assurance system of the high support formwork frame. Through the successful implementation of the actual project, it is shown that good construction guarantee measures are the important factors for the successful implementation of the design die frame. The calculation and comparison of the high support die frame and the corresponding construction quality assurance system in this paper make the high support mould frame carry out smoothly in this project, which has certain reference function to other similar projects.
