【摘要】：现如今随着科技不断进步和社会经济的快速发展,我国复杂钢结构的应用越来越广,钢结构的大跨、超高层建筑愈来愈多,它们在施工过程中的力学问题也越来越受到广泛的关注。此种类型构造别致但受力繁杂,以及安装时的技术难度比较大,导致施工时出现很多不利影响因素,所以其安装技术受到越来越多的关注。于是为保证工程建造安全、经济、顺利,要求在安装过程当中根据客观条件确定经济合理的安装次序。非常有必要针对其进行安装过程模拟分析以解析结构在施工阶段的力学分析和钢结构安装技术的分析。本文以目前我国钢结构施工技术发展近况为背景,在查阅相关文献的基础上,对该项目进行了复杂钢结构安装技术分析。本文的主要研究内容有:在已有的国内外钢结构现状研究基础上,对复杂钢结构施工阶段进行剖析,结合具体项目,对其安装技术进一步研究。首先介绍了基本的工程概况,钢结构概况主要分布于台塔、观众厅、前厅。本工程重难点分析包括前厅重难点分析及应对措施、观众厅重难点分析及应对措施、台塔重难点分析及应对措施;其次对吊装方案、施工技术进行分析,钢结构进行了吊装模拟仿真分析等;最后对钢结构加工制作方案分析包括焊接H型钢加工制作方案、箱型构件加工制作方案、焊接方案和工艺、焊接缺陷及对策进行了分析。本文通过对复杂钢结构安装技术的分析,强调要重视钢结构施工的仿真模拟分析,以避免事故的发生,进一步提高施工技术水平。
[Abstract]:Nowadays, with the continuous progress of science and technology and the rapid development of social economy, the application of complex steel structure in our country is more and more extensive, the long span of steel structure is more and more, and there are more and more super high-rise buildings. Their mechanical problems in the construction process have been paid more and more attention. This type of structure is chic but complicated, as well as the technical difficulty of installation, resulting in a lot of adverse factors in construction, so more and more attention has been paid to its installation technology. Therefore, in order to ensure the safety, economy and smooth construction of the project, it is necessary to determine the economic and reasonable installation order according to the objective conditions in the installation process. It is necessary to carry out the simulation analysis of the installation process to analyze the mechanical analysis of the structure in the construction stage and the analysis of the installation technology of the steel structure. Based on the recent development of steel structure construction technology in China, this paper analyzes the installation technology of complex steel structure on the basis of consulting the relevant literature. The main research contents of this paper are as follows: on the basis of the existing research on the present situation of steel structure at home and abroad, the construction stage of complex steel structure is analyzed, and the installation technology is further studied in combination with specific projects. First of all, the basic engineering situation is introduced. The steel structure is mainly distributed in the tower, audience hall and front hall. The analysis of the major and difficult points of the project includes the analysis of the difficulties and the countermeasures of the front hall, the analysis of the difficulties and the countermeasures of the audience hall, the analysis of the difficulties of the tower and the measures to deal with them. Secondly, the hoisting scheme and construction technology are analyzed, and the hoisting simulation analysis of steel structure is carried out. Finally, the analysis of steel structure machining scheme includes welding H-beam processing scheme, box component processing scheme, welding scheme and process, welding defects and countermeasures. Based on the analysis of the installation technology of complex steel structure, this paper emphasizes that attention should be paid to the simulation analysis of steel structure construction in order to avoid the occurrence of accidents and further improve the construction technology level.
