【摘要】：模块化钢结构建造是指将整体钢结构分成多个模块同时建造最后进行整体组对的钢结构建造技术。目前,国内外模块化钢结构工程建设规模向着大型和巨型发展,其内部设备数量众多,重量重,体积大,很多设备到达施工场地时是散装,需要进行组装、成撬;同时,穿甲板设备多,设备安装、就位、组对等困难。为了对模块化钢结构内部设备的安装施工进行合理的安排、保证设备安装的效率与质量、降低工程总成本和保证工程顺利实施,采用科学的设备安装施工方法和先进的技术手段是非常必要的。为此,本文主要进行了以下研究工作: 首先,详细分析了模块化钢结构工程大型设备组装、安装的特点,以及目前大型设备组装安装过程普遍采用的“定位找正调整法”和“预装整体调整法”安装技术的特点与不足; 其次,针对钢结构工程很多设备到达施工场地时是散装,需要现场进行组装、成撬过程等特点,着重分析了设备组合件装配的特征,并把它抽象为组合件装配信息模型,利用装配模型实现设备组合件快速装配; 模块化钢结构工程设备重量重、数量巨大,设备贯穿多层甲板甚至多个模块,为保证设备吊装安全,特别是贯穿甲板片型设备的安装尺寸精度与连接尺寸精度,提出大地坐标尺寸定位法来定位贯穿型设备,分析了吊装工具及机具的设计校核; 最后,将先进制造技术——虚拟装配技术引入模块化钢结构设备组装、安装过程,构建了大型设备空间模块内虚拟装配体系。通过对两层甲板之间的设备及环境之间的装配进行分析提出了空间模块内虚拟设备装配路径规划及装配过程仿真。
[Abstract]:Modular steel structure construction refers to the steel structure construction technology that divides the whole steel structure into several modules and builds the whole steel structure at the same time. At present, the construction scale of modular steel structure engineering at home and abroad is developing towards large scale and giant. Its internal equipment is numerous in quantity, heavy in weight and large in volume. When many equipments arrive at the construction site, they are in bulk and need to be assembled and pricked; at the same time, More decking equipment, equipment installation, position, group parity difficulties. In order to arrange the installation and construction of the internal equipment of the modular steel structure reasonably, to ensure the efficiency and quality of the installation of the equipment, to reduce the total cost of the project and to ensure the smooth implementation of the project, It is necessary to adopt scientific installation and construction methods and advanced technical means. For this reason, this paper mainly carries out the following research work: firstly, the characteristics of large equipment assembly and installation in modular steel structure engineering are analyzed in detail. As well as the characteristics and shortcomings of the installation technology of "position-seeking adjustment" and "pre-assembly integral adjustment", which are commonly used in the assembly and installation process of large equipment at present; secondly, In view of the fact that many equipments of steel structure engineering arrive in bulk when they arrive at the construction site, they need to be assembled on the spot, and the process of prying, etc., this paper emphatically analyzes the characteristics of assembly of equipment assemblies, and abstracts it into the assembly information model of assembly parts. In order to ensure the safety of equipment hoisting, modular steel structure engineering equipment is heavy in weight and large in quantity, and runs through multiple decks or even multiple modules. Especially, the installation dimension accuracy and connection dimension accuracy of perforating deck plate type equipment are analyzed. The geodetic coordinate dimension positioning method is put forward to locate the penetrating equipment, and the design and check of hoisting tools and machine tools are analyzed. The advanced manufacturing technology, virtual assembly technology, is introduced into the assembly and installation process of modular steel structure equipment, and the virtual assembly system of large equipment space module is constructed. The assembly path planning and assembly process simulation of virtual equipment in space module are proposed by analyzing the assembly of equipment and environment between two decks.
