【摘要】：近年来,大型复杂空间钢结构形式在我国的建筑中发展迅速,应用范围越来越广。原因是其受力合理、刚度大,适合用于大空间、大跨度的建筑,其制作安装的方便也适合各种形状、类型的设计。同时,随着空间钢结构的表现形式变得复杂多样,曲面造型的大量出现,使建造的难度随之增大,对建筑施工的要求也提高了。建造过程中的流程部署、测量定位、结构受力和卸载变形等,对安装的质量都有很大的影响,因而对大型空间多曲面结构整个安装过程进行技术模拟分析及对其安装质量控制的关键点进行研究是十分有现实意义的,它可以为此后复杂曲面钢结构吊拼装的技术质量管理提供经验支持。本文对大型多曲面复杂空间钢结构施工中的安装技术质量管理的策划、过程控制措施等进行探讨,说明了现阶段此类复杂工程技术质量管理的进展和关键控制点。首先,对大型杂空间钢结构常见安装方法进行分析类比,结合广州亚运体操馆的多曲面钢结构安装工程设计特点对结构施工的全过程安装设定思路,其安装质量方法可以按原有的高空散拼法和单元安装法两者的质量管理方式结合使用。依据工程的质量控制目标与安装的过程特点,从管理体系、人员架构、各阶段的过程控制等方面进行钢结构工程安装质量技术管理策划,分解为各分项工程的质量管理和对支撑和卸载等临时工程的管理。最后,结合亚运体操馆的施工实际效果,得出质量控制的关键技术措施,主要控制点是在于是加工、预拼装等阶段的测量定位,双曲空间桁架的吊运、组拼装过程控制,以及组合支撑架的设计使用对安装精度的支持以及利用架支撑进行整体卸载、结构变形控制等。综上所述,结合大型多曲面空间钢结构安装过程模拟及相关安装控制技术,对此类安装工程的施工组织、质量监控策划有着关键的作用。本文所记录的空间桁架安装、曲面结构测量定位、组合支撑胎架的使用等对今后大跨度多曲面空间结构的技术质量控制工作有着重要的参考价值。
[Abstract]:In recent years, large and complex spatial steel structures have developed rapidly in our country, and have been used more and more widely. The reason is that its force is reasonable, stiffness is large, suitable for large space, long span buildings, its easy to make and install also suitable for various shapes and types of design. At the same time, with the complexity and diversity of spatial steel structure and the appearance of curved surface, the difficulty of construction is increased, and the requirement of construction is raised. The process deployment, measurement and positioning, structural stress and unloading deformation during the construction process have a great impact on the quality of the installation. Therefore, it is of great practical significance to simulate and analyze the whole installation process of the large space multi-curved structure and to study the key points of its installation quality control. It can provide experience support for the technical quality management of steel structure crane assembly with complex curved surface. This paper discusses the planning of installation technology quality management and process control measures in the construction of large multi-curved complex spatial steel structure, and explains the progress and key control points of this kind of complex engineering technology quality management at present. First of all, the common installation methods of large miscellaneous space steel structure are analyzed and compared, and the whole process of installation of the structure is set according to the design features of the multi-curved steel structure installation engineering of Guangzhou Asian Games gymnasium. The method of installation quality can be used according to the quality management mode of the original aerial scattering spelling method and the unit installation method. According to the quality control objectives and installation process characteristics of the project, the management system, personnel structure, process control of each stage of steel structure engineering installation quality and technical management planning are carried out. Decomposed into sub-project quality management and support and unloading of temporary works management. Finally, combined with the actual construction effect of the Asian Games gymnasium, the key technical measures of quality control are obtained. The main control points are the measurement and positioning in the processing, pre-assembly and other stages, the lifting of hyperbolic space truss, and the control of assembly process. The design of the combined support frame uses the support of the installation precision, the overall unloading of the frame support, the deformation control of the structure, and so on. To sum up, combined with the simulation of the installation process of large multi-curved space steel structure and the related installation control technology, it plays a key role in the construction organization and quality control planning of this kind of installation project. The installation of space truss, the measurement and positioning of curved surface structure, and the use of combined support tread are of great reference value for the technical quality control of large span multi-curved space structures in the future.
